Abbey National
Millington to take early retirement from Abbey National
Mac Millington (52), customer operations director at Abbey National is to take early retirement after a 28-year career at the UK bank.
Millington will step down later this year and will remain with Abbey until a suitable successor is appointed.
His departure comes at an awkward time for the UK bank, which has restructured its business to focus on customer relationship management in the personal finance area after a disastrous expansion into corporate and investment banking.
A former group IT director, Millington oversaw the launch of stand-alone Internet bank cahoot in 2000 and was appointed to the board of Abbey National in January 1999. He took on his present role after a one-year stint as managing director of wealth management and long-term savings.
Luqman Arnold, chief executive of Abbey National, says: "Mac first discussed his intention to take early retirement with the chairman at the end of last summer, so I'm very grateful to him for agreeing to put the business before his personal plans and help us to lay the foundations for the successful delivery of our new strategy."
As part of the new strategic direction, Abbey National recently hired Dr Angus Porter as customer propositions director, with overarching responsibility for the company's three customer-facing divisions. A former managing director of BT's consumer division, Porter takes over his new job next week.

Hollywood royalty and elder statesman of the silver screen, Bahamian-American actor Sidney Poitier, whose trailblazing work in the 1950s and '60s helped break colour barriers, shifting the lens through which Black people were perceived and paving the way for other Black actors to make their mark, died on January 7 at the age of 94. BREAKING: Beloved Bahamian actor and former ambassador Sir Sidney Poitier has …


The 2016 Audi A3 is a compact, luxury sedan that carries the entry-level banner for the Audi brand. Unlike some previous attempts by the company to create an affordably-priced compact sedan for premium buyers, the A3 actually feels like an uncompromised Audi.
Honestly, the Audi A3 is so well done that many premium buyers who normally look to larger vehicles in the VW Group's premium lineup, but who could be better served by a more compact offering, will be drawn in by this car. The 2016 A3 is upscale, drives like a premium sedan should, all while retaining the sportiness that we've come to expect from the Audi brand.
There's both a sports sedan and convertible option for the Audi A3, seating five and four people respectively. The design of the 2016 A3 carries over from its introduction last year with just a few tweaks to improve the trim option lineup.
On the outside, the A3 is a well-designed car with minimal flair and maximum presence. A short, well-curved hood and rather tallish windshield mark it as being maneuverable and roomy and the heavy, thickened cut for the running board line makes the only eye-catching adornment along the sides. The upper beltline fold is long, running from the point of the headlight to the top of the tail lamp, but it's that lower running line that creates the stylized movement of the Audi A3's design. A coupe-style roof and clipped deck lid finish the job in signature Audi style. This look, which is contemporary to the Audi car lineup, fits well in the dealer lot while standing out for its sharp simplicity on the street.
Inside, a host of well-chosen materials and top notch craftsmanship set the tone for the interior. The round steering wheel is flanked by rounded (and very useful) vents that sit atop a curved dashboard. The round shift knob and deeply rounded edges of the front seats create an overall theme of soft curvature within the cabin. This is only broken by the large, square infotainment screen when it rises from the dash upon vehicle startup. It stows when not in use or upon command, though, to restore the smooth feel of the dashboard.
Instruments inside the 2016 Audi A3 are very visible and quick to read. Their throwback round dial nature is a nice touch, keeping the car's sportiness always at the fore. The infotainment is simple, but effective and the linear menu system is easy to follow and use, though it can be tedious at times.
The rear seating is cramped for taller adults, but comfortable and of a good size for the class. Those who tote children around or rarely have more than a front passenger won't mind the compact size of that rear seat bench. Grown adults can sit there if required and anyone of average size will find it good enough for short trips. Trunk space is a mere 10 cubic feet, though, making the car less versatile than some might expect. The rear seats fold down to expand that, however, and if the all-wheel drive is not opted for, the trunk expands to about 12 cubes with the driveshaft and differential delete.
A 1.8-liter turbocharged four-cylinder brings 170 horsepower and 200 pound-feet of torque to the game.
A turbocharged 2.0-liter four-cylinder ups that to 220HP and 258 lb-ft.
Finally, a diesel option (TDI) is offered with a 2.0-liter four-cylinder that elicits 150HP and 236 lb-ft.
We drove the 2.0L gasoline version and loved its pep. This engine comes standard with AWD (aka "quattro"). Acceleration to sixty mph is easily doable in under six seconds with the 2.0L gas and the signature Audi suspension trim and handling adding in to make this a very fun little car to drive. Fuel economy is rated at 27 mpg combined in this sedan, with the 33 mpg highway rating being entirely doable by most drivers who aren't too hard on the throttle.
On the road, the A3's ride quality is excellent no matter the situation. It's a quiet sedan on the highway and a fast mover around town. Its size makes it nimble by nature and easy to park. This is a great compact offering from Audi, for sure, and one of the few on the market that truly carries the brand's core with it.
Great Scott, The DeLorean Is Going Back Into Production!

Q: Why does getaddrinfo return ipv6 address instead of cname in ai_cannonname? My code has:
hints.ai_flags = AI_CANONNAME;
hints.ai_family = AF_INET6;
ret_ga = getaddrinfo(hostname, NULL, &hints, &res);

When hostname is ipv6.google.com,
res->ai_canonname is returning 2607:f8b0:4005:802::1006.
I expected/want the cname
ipv6.l.google.com.
When I try this on ipv4.google.com, I get the cname nuq05s02-in-f9.1e100.net.
Do I need to set some other ai_flags in order to get the cname for ipv6.google.com?

Updated April. 20, 2017 07:14
Xi Jinping says Korea was a part of China. April. 20, 2017 07:07. by In-Chan Hwang hic@donga.com. It has been reported that during a two-day summit between U.S. President Donald Trump and his Chinese counterpart Xi Jinping on April 6 and 7, Xi said Korea had been a part of China and Trump showed a gesture of consent. After the news was delivered, it has provoked a controversy in South Korea.
In an interview with the Wall Street Journal on April 12, Trump reportedly said, "(Xi) then went into the history of China and Korea. Not North Korea, Korea. And you know, you're talking about thousands of years …and many wars. And Korea actually used to be a part of China."
"After listening for 10 minutes, I realized it's not so easy," said Trump. Trump's comments had not been published by the Wall Street Journal right after the interview and instead a full transcript of the interview was uploaded later on its website.
In regard to the conversation between two leaders, U.S. online news publisher "Quartz" said on Tuesday, "Trump weirdly says Korea was "part of China," which is totally wrong and could enrage South Korea." Korea was temporarily occupied by China for a few years when the Han Chinese set up its military bases in the Northern part of Korea before the birth of Christ or during the expansion of the Yuan Dynasty in the 13th century. However, Korea was hardly a part of China at every angle.
Trump has also been criticized for his confusion of differentiating former North Korean leader Kim Jong Il from his son and current leader Kim Jong Un. His fundamental awareness of issues related to North Korea has been questioned. In an interview with Fox News on Tuesday, Trump said former Presidents Bill Clinton and Barack Obama had been talking with this gentleman, referring to Kim Jong Un. However, it was Kim Jong Il whom Clinton met.

Micropileadmin2021-11-28T00:31:34+03:30
What is micropile?
Generally, in the face of problematic soils such as loose soils with low bearing capacity, high settling capacity, liquefaction, manual soils, etc., there are two ways for geotechnical engineers:
A) Using the load-bearing elements in the soil
B) Improvement and modification of physical-mechanical properties of soil mass.
Each of the above solutions has its methods and specifications that have been developed over the years. Some innovative techniques also have the nature of a combination of the above two categories and have the advantages of both categories to some extent. Among them, we can mention the use of micropiles with the injection of cement slurry.
Piles are generally divided into two main groups: displacement piles and replacement piles. Micropiles are small replacement piles (usually less than 300 mm in diameter) that are often associated with light steel reinforcement and cement slurry injection. Micropiles can be designed and implemented from any angle and can be used for a variety of purposes, including bearing axial and lateral loads, replacing conventional piles, or as part of a combined soil-pile system, depending on the design goal.
Micropile in addition to acting as a load-bearing element and resistant to settlement, due to the injection of cement slurry, also improves the strength characteristics of the surrounding soil.
Micropile is a small diameter pile with a light steel reinforcement in which the cement slurry injection technique is used. According to the FHWA regulations, micropiles are less than 30 cm in diameter, while in Iran they are typically about 8 to 15 cm in diameter.
The components of the micropile system in Iran include casing, reinforcement, and flange connecting to the foundation and cement slurry. The casing has holes at appropriate intervals that allow injection under pressure into the soil.
The construction of the micropile system also includes the steps of drilling a borehole, placing a casing in the soil, injection of cement slurry, installation of reinforcement, and installation of a connecting flange, which are described in the following sections.
History of micropiles
Micropiles were invented in Italy in the early 1950s to reinforce the foundations of historic buildings that had been damaged over time, especially during World War II. An Italian contractor named Fondil first introduced root piles. These small in-situ piles were small in diameter, often reinforced with light steel reinforcement and cement slurry injection.
Initially, most applications of micropiles were limited to reinforcing existing infrastructure in urban environments, but in 1957 new engineering needs leading to the introduction of new systems called micropiles called reticulate micropiles. It is a three-dimensional network of vertical and oblique micropiles that form a composite structure of soil and pile and is laterally bounded.
Foundil (1962), used this method to strengthen historic buildings in England. Also in 1965, this method was used in the German underground transport system, after which the term micropile replaced the name of the root pile. These micropiles are used to stabilize slopes, reinforce coastal walls, protect buried structures, reinforce soil, and other soil and structure reinforcement methods.
Micropile implementation steps
The method of micropile implementation includes four stages of drilling, Pile driving, injection, and reinforcement, the steps of which are described below.
In general, micropile pipes are placed either by percussion or drilling. Placement through percussion significantly improves the bearing performance of micropiles due to the friction between the pipes and the surrounding soil wall and its effect on increasing the injection pressure of cement slurry. Placement through drilling causes corrosion in different layers of soil and practice, a larger diameter should be drilled than the outer diameter of the pipes. For this reason, drilling operations are used only in situations where pipe drilling is not possible (mainly at great depths). Drilling operations are carried out in different methods such as rotary drilling or down the hole drilling (D.T.H).
After drilling, micropile pipes are hammered in the specified places by pile driving machines. The pipe of the first piece is bayonet and the next pieces are completely connected by socket and welding, respectively. The pile driving operation will continue as long as it is possible to knock the pipes, and if the pipe does not sink more than 10 cm for 30 consecutive blows, the pile driving operation will be stopped.
In this case, drilling is done until the depth of the design is realized and then the pipes related to micropile are installed inside the borehole.
Micropile pipes have an outer diameter of 76 mm and an inner diameter of 68 mm in two-meter pieces. These pipes are connected by socket and welding. Each micropile has 80 holes with a diameter of 8 mm per meter. The internal environment of the pipes should be برقوزده so as not to have negative effects on grout injection.
Injection devices consist of three parts: primary mixer, secondary mixer, and injection pump. Mixing in the primary mixer is of the rapid water circulation system type and the secondary mixer is of the vane type. The injection slurry is made in the primary mixer by first pouring the desired amount of water into the mixer and then adding cement to the required ratio of water to cement. The minimum mixing time of cement slurry is 30 seconds. The ratio of water to cement used is between 0.5 and 1.5 depending on soil conditions. After preparing the slurry, for maintenance, the slurry is poured into the secondary mixer and then injected by special injection pumps. To inject the slurry into the micropile pipes, special hoses called a packer are used, which when injected, the packer sticks to the wall of the pipe and prevents the slurry from leaving.
For example, the first step of closing the packer for the 8-10 m micropile is at a depth of 6 meters. After the injection operation at a depth of 6 meters, the packer is closed at a depth of 4 meters, and after the injection is completed at this stage, the packer is closed at a depth of 2 meters, and finally, after injection at this stage, the wellhead packer is closed and the injection operation is completed.
Injection specifications
Injection pressure: Injection pressure can vary at different injection stages and depths, under the influence of soil type and geotechnical conditions. The maximum injection pressure is limited to 10 atmospheres
Amount of cement used: Depending on the geotechnical conditions and the load-bearing capacity of the micropile design, the estimated amount of cement can be equal to each micropile length up to 100 kg. However, since the injection should be continued up to a pressure of 10 atmospheres, so the amount of cement may be higher than the initial estimate.
Water to cement ratio: The water to cement ratio in the injection slurry used can be between 0.5 and 1.5 under normal conditions and the water to cement ratio of the slurry in other conditions can vary from 0.67 to 1. It should be noted that the slurry ratio in each section is determined at the suggestion of the contractor and the approval of the monitoring device.
Type of cement used: The type of cement used in cement injection mortar is Portland cement type I, type II or type V cement, which is determined according to the chemical conditions of the desired location.
Water used: The water used in the preparation of slurry should be clean and smooth and has all the necessary conditions for water consumption in concrete construction. Water used must be free of any substances such as acids, alkalis, sugars, salts, and organic matter that can damage the concrete. The water used in the manufacture of injection slurry should have suspended solids less than 0.2%, soluble substances less than 3.5%, chlorine content less than 1%, sulfate content less than 0.3%, and alkali content less than 0.06%. In general, drinking water is suitable for making a slurry.
Arming and installing flanges
In the case of bearing micropiles, it is necessary to place the reinforcement inside the micropile tube and install the flange. The reinforcement must be installed inside the borehole before the cement setting.
The flange, which is used to create a complete connection between the micropile and the foundation concrete, as well as to prevent cone shear of the micropile head inside the foundation concrete, must be welded to the micropile reinforcement in the last step.
Optimal conditions in the implementation of micropiles
Various factors are effective in selecting micropiles for the foundation and slope stability. These factors include:
Access restrictions in remote areas
Proximity to existing buildings
Underground conditions
Difficult geological conditions;
Lands prone to liquefaction during pile installation
– Vibration and noise-sensitive areas;
– Dangerous or contaminated soils
Compatibility with existing structures
Limitations of micropiles
Physical conditions
The drilling and injection equipment used to install the micropile is relatively small and can be installed in confined areas where it is not possible to pass the pile installation equipment. Micropiles can be installed inside walls and foundations with dimensions of several millimeters. their installation is not affected by their upper force or other obstacles in the installation of piles.
Installation equipment can move in areas with steep slopes as well as remote areas. Also, drilling and injection operations related to the installation of micropiles will not cause damage to adjacent buildings if performed properly.
Subsurface conditions
Micropiles can be installed in areas with harsh, variable, and unpredictable geological conditions, such as lands with cobble and boulder and underground facilities, or the presence of various debris and irregular lenses of weak materials and components.
Soft clays, sand dunes, and high groundwater levels, which are considered unfavorable conditions in the traditional installation method, have the least impact on micropile installation. Micropiles are used worldwide in karstic calcareous formations.
Micropiles can be installed in hazardous and contaminated soils. Their small diameter reduces the amount of losses during installation compared to traditional replacement piles. The slurry mixture can be designed to be resistant to the chemical activity of water and soil. In the slurry mixing scheme, additives can be used to prevent the deterioration of concrete in acidic and corrosive environments.
Micropiles can be installed in sensitive areas, such as areas of fragile nature. Their installation equipment is not as large or heavy as ordinary drilling and pile installation equipment and can be used in sludge fields or other areas with soft and moist surface soil, with minimal impact on the environment. Portable drilling equipment is commonly used in restricted areas.
Installing micropiles creates less noise and vibration than conventional traditional pile installation techniques such as pile driving. Vibrations generated during drilling are transmitted first to the soil and then from the soil to adjacent buildings. The use of micropiles in old and industrial urban areas can prevent this destructive effect on sensitive equipment and adjacent structures.
Micropiles can be installed in areas where a contaminated aqueous layer is located on a load-bearing layer. Unlike driven piles, which may create a vertical conduit for contamination, micropiles can be installed in such a way as to prevent contamination of the underlying aquifers.
Micropiles can be added to existing pile caps. Therefore, the need to increase the dimensions of the foundation is eliminated. This action provides additional compressive, tensile, and flexural strength requirements when increasing the load on the structure. Sometimes the limitations of adjacent structures do not allow us to increase the dimensions of the existing pile cap. Therefore, the need for conventional candle installation systems is eliminated.
In some cases, vertical micropiles may be limited in terms of lateral bearing capacity and cost reduction. They are also assumed to have limited axial bearing capacity due to their small relative diameters. Although in the experiment, the micropiles have withstood an axial load of 4,500 kN in dense sand, so it is expected that further lateral load capacity will be increased with further research and testing. The ability to install micropiles obliquely helps designers to achieve the required lateral bearing capacity. The cost of implementing micropiles is usually higher than traditional pile installation systems, especially driven piles. But in some special cases, micropiles are an economical option and at the same time the only possible solution for building and executing a project. The use of micropiles in stabilizing slopes at limited altitudes has been based on past limited experiences. Due to the limited number of implemented projects, it is recommended that slopes be instrumented and monitored in stabilization applications.
The economics of micropiles depends on many factors. It is very important to evaluate the cost of implementing micropiles with respect to the physical, environmental, and subsurface conditions described above. For example, for a site with soft, clean, uniform soil and easy access, micropile However, for sensitive foundations under bridge piers in old residential or industrial areas with heavy traffic, micropiles can be considered as an economical solution.
The slurry mixture can be designed to withstand the chemical activity of water and soil. Special compounds can be used in the design of the slurry mixture to increase its resistance to acidic and corrosive environments.
Cost analysis should be done taking into account all costs related to the project and not just the costs associated with the installation of piles.
These costs may include the following:
Drilling, pile driving, and embankment requirements;
Execution of foundation;
Carrying hazardous materials;
Lowering the groundwater level;
Erosion control;
Access restrictions;
Land improvement and…
According to the explanations provided in the previous section, the use of micropiles can be generally expressed in the following two sections:
Use of micropiles as a load-bearing element
Use of micropiles with the aim of soil improvement
The primary use of micropiles is as a load-bearing element. Many studies have been done in this field and its design methods are also available in various sources. But unlike the first part, the use of micropiles with the aim of soil improvement is a new issue that has been raised in recent years and limited studies have been conducted on it. Currently, in Iran, micropiles are used in the following four areas:
– Used as a load-bearing element under the foundations of buildings
– Used as a load-bearing element to repair the foundations of old buildings
– Used as a load-bearing element under the foundation of other superstructures (bridge abutment, oil and gas tanks, etc.)
– Used to improve the soil and increase its resistance and behavioral parameters
– Used to improve the soil and deal with the phenomenon of liquefaction
Micropile classification system
The classification of micropiles is based on two criteria:
-How to design
-Procedure
Classification by design type
The design of a single micropile or group of micropiles is very different from the design of reticulated micropiles. This has led to the definition of two design categories for micropiles. In the first category, micropiles are loaded directly and the reinforcements bear most of the applied load. In the second category, micropiles are placed in the soil as a network and create a reinforced soil composite system that can withstand the applied loads. This hybrid system is the same network of reticulated micropiles.
In the first category, micropiles are used as an alternative to traditional piles to transfer the load of the structure to the underlying resistant layers. These micropiles are designed to perform individually, even if run in groups. In the second group, micropiles have lighter reinforcement because the reinforcers, like the first group, are not directly loaded and it is the mass of soil and piles that bears the applied loads. In addition to these two categories, another type of micropile is used in Iran, which is known as consolidation micropile. Consolidation micropiles are similar to network micropiles in terms of behavioral philosophy, except that it does not use reinforcement. Cement slurry injection is the main part of consolidation micropile, which increases soil resistance and behavioral parameters.
Classification based on the implementation method
The injection method is the most important factor affecting the bond resistance between the ground and the slurry. In such a way that the resistance of the band changes directly by changing the injection method. In this classification, the criterion is the injection method and its pressure, and the use of sheaths and reinforcements determines the sub-sections of this classification. In this classification, micropiles are divided into 4 categories.
Type A: In this method, the slurry is placed under its weight.
Type B: In this method, the cement slurry is injected into the borehole under pressure after the steel sheath comes out of the borehole. The injection pressure usually varies between 0.5 and 1 MPa and should be such as to prevent hydraulic failure.
Type C: Type C represents a two-step process in which the cement slurry is first placed under its weight inside the cavity (as in type A). Then, before the initial slurry hardens (after about 15 to 25 minutes), the same type of slurry is injected, at the point of contact of the slurry with the ground and at a pressure of at least 1 MPa through the lattice injection pipes without the use of a packer. This type of micropile is used only in France.
Type D: Type D is a two-step injection process similar to type C, but with changes in the second step. First, the cement slurry is uniformly placed under its weight, such as type A and C, or under pressure, such as type B, in the cavity. After the initial slurry hardens, the next slurry is injected through lattice injection pipes at a pressure of 2 to 8 MPa. In this method, the packer is used so that special surfaces can be modified several times if necessary.
The construction of micropile system has special advantages in comparison with other methods of foundation construction and soil improvement, which can be considered as follows:
It requires less equipment than prefabricated or in-site pile construction equipment.
It can be used in lands that have limited working space (for example, in the basement of old structures or under the decks of bridges, etc.).
It has high execution speeds.
It is easy to work with its equipment.
It can be used to increase the bearing capacity of existing foundations because of its high flexibility.
It can be used in urban environments due to less noise and vibration caused by the installation.
It is easy to perform various tests on it, such as compressive, tensile, and lateral loading tests.
Principles of micropile design
The principles of micropile engineering calculations depend on the micropile usage type and its behavior. In the case where micropiles are used to consolidate and improve the foundation of structures, the technical calculations of micropiles are similar to the calculations of conventional piles. These calculations are based on three parts: structural design, geotechnical design, and cone shear control.
In the structural design, the bearing capacity of micropile elements including steel wall, reinforcement, and cement slurry is calculated. This capacity should be higher than the load applied on the micropile.
In the geotechnical design, the frictional resistance of the micropile wall with the surrounding soil is calculated. This friction resistance should be higher than the applied load to prevent the micropile from separating from the soil before the surrender of the reinforcing agents.
In the final step of the design, since the micropiles have a high concentrated load and small diameter and the cone shear is possible due to the applied overheads, control of the resistance against cone shear is performed, which leads to a suitable flange design.
Design methods
Service load design (SLD) or allowable stress method
In this design method, which is often used by geotechnical engineers, the design is such that the allowable load is always greater than the design load.
Load factor design (LFD) method
In this method, using factors of load increase and decreasing resistance, the design is done in such a way that the design resistance is always greater than the required resistance.
Both design methods try to compensate for the uncertainties in the load and the properties of soil and materials that arise from their inherent random nature by applying a coefficient of reliability.
Performance quality control
To ensure that the micropiles are capable of withstanding the intended design load without additional displacement and with sufficient reliability during their service life, a field load test is performed on the micropiles.
In addition, using these tests, it will be possible to control the performance of the contractor during execution and after drilling, installation, and injection operations.
The following purposes are considered in all loading tests:
Achieve a predetermined maximum load;
Achieve a predetermined axial displacement;
Achieve a predetermined creep threshold;
Loading tests are divided into four general categories:
Final test: In this test, the load continues to the point of rupture between the soil and the slurry (without increasing the load, the displacement increases).
Verification test: This test is performed to check whether the execution method is capable of supplying the intended band resistance. The magnitude of the test load is determined according to the considered reliability coefficient. For example, if a reliability coefficient of 2.5 is considered, the test load is 250 times the design load. In the validation test, the micropile does not necessarily reach the rapture point. This test is usually performed on the Ghorbani's micropile before construction begins. It is also performed during implementation to determine capacities in different soil conditions and different methods.
Proof test: This test is usually performed on a percentage of micropiles (about 5%). This test is performed by increasing the step load to a percentage of the design load (recommended by Regulation 167). The micropile ability to withstand service loads without large displacement is controlled using this test.
Creep test: This test is usually performed in addition to the previous three tests (final, verification, and proof). The creep test involves measuring the amount of displacement, at a constant load, and specified intervals. A maximum displacement of about 2 mm at each time point is the acceptance criterion. The purpose of this test is to evaluate the safety of the system against design loads during operation.

Q: Why System.Windows.Interactivity doesn't want to work? I just added this line to my XAML file:
xmlns:interactivity="clr-namespace:System.Windows.Interactivity"

First I get an Undefined CLR namespace error but after a build it was fixed. Now when I try to add an interactivity tag in mt XAML file I get an complete error on this namespace.

To finish I would like to let you know I installed Blend but never opened it or used it.

A: This is  the correct namespace for interactivity within XAML:
xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"

A: You need to provide assembly name for namespaces which resides in different assemblies. Declare namespace like this:
xmlns:interactivity="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

A: First, add the MVVM Light NuGet package, which will add a reference to System.Windows.Interactivity.dll
However, sometimes, when you add a new NuGet package, in might introduce a clashing version of System.Windows.Interactivity.dll.
This prevents the project from working.
To fix, add an Assembly Binding Redirect by editing your app.config to look something like this:
<?xml version="1.0"?>
<configuration>
<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly>
      <assemblyIdentity name="System.Windows.Interactivity"
                        publicKeyToken="31bf3856ad364e35"
                        culture="neutral"/>
      <bindingRedirect oldVersion="4.0.0.0"
                       newVersion="4.5.0.0" />
    </dependentAssembly>
  </assemblyBinding>
</runtime>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/></startup>
<appSettings>
  <add key="TestKey" value="true"/>
</appSettings>

Don't worry about changing the PublicKeyToken, that's constant across all versions, as it depends on the name of the .dll, not the version.
Ensure that you match the newVersion in your appConfig to the actual version that you end up pointing at:

A: There is also an option to use Blend for Visual Studio itself to add all necessary references where needed. You simply open up your solution in Blend, then you navigate to the view file you want Blend behavior to add to. After opening the view, you have to switch from Solution Explorer to Assets tab, select Behaviors and double-click wanted action, e.g. CallMethodAction.
Blend will automatically add references to System.Windows.Interactivity and Microsoft.Expression.Interactions, XML namespaces and also generate XAML code. You have to save changed file in Blend, switch to Visual Studio and reload solution to apply changes.


A single row of 36 male pin headers, these male pin headers are 0.1" (2.54mm) pitch and can be cut to any size. They are mainly used to connect the ArduPilot Mega and the Oilpan Shield together, if you have bought the "Oilpan with pins" you will not need to buy these. The Conn Male Headers can also be used with any custom PCBs, Air speed sensor kits or as general custom headers for electronic projects.

Meningococcal - Meningitis
Vaccination against meningococci
Vaccination against meningococcal group B
Monovalent vaccination against group C meningococci
Vaccination against meningococci of group A, C, W135 and Y (MEC-4)
Video: Meningococcal - Meningitis
Video: Meningococcal meningitis: Doctor discusses causes, symptoms, treatment, prevention 2023, January
Meningococci are bacteria that settle in the nasopharynx and cause meningitis (meningococcal meningitis) and blood poisoning (meningococcal sepsis). Meningococci are transmitted via droplet infection. The incubation period for meningococcal disease is one to ten days, usually less than four days. The disease can lead to death within a few hours in full health.
Meningococci occur worldwide, groups A, B, C, W135 and Y have the greatest importance for the occurrence of invasive diseases. In Austria there are around 20 to 100 cases of disease annually (approx. 50 to 74 percent due to meningococci of group B and ten up to 30 percent due to meningococci of group C). The disease occurs most often in the first year of life and in adolescents.
Only a few individual cases of infections with groups A, Y and W135 are currently observed in Austria. Classic high-risk areas for meningococci A or W135 are Africa and the Middle East: in Africa the Sahel zone, but also the East African lake district (e.g. Tanzania) and North Africa are affected. This disease is also native to the Middle East and Saudi Arabia.
Meningococcal epidemics are favored due to the transmission as droplet infection when many people come together in a confined space.
The death rate from blood poisoning (sepsis) from meningococci is around 30 percent. Bacterial meningitis (meningitis) or sepsis and meningitis can also occur together. The overall mortality rate for meningococcal diseases in Austria in the years 2003–2017 was between five and 25 percent. During this period, 95 people (mostly children and adolescents) died of this disease. The survivors often suffer from severe damage to their health, such as neurological and developmental disorders, hearing loss, loss of body parts, extensive scarring or chronic pain.
For more information, see Meningococcal Meningitis and Bacterial Meningitis.
Child vaccinations: The vaccination against meningococcal B is not included in the free vaccination program. Due to the epidemiological situation, vaccination is recommended for all children and adolescents as early as possible from the age of 2 months in order to achieve protection against invasive meningococcal B diseases
Note If the vaccination is given together with other child vaccinations (six-fold, pneumococcal and measles, mumps and rubella vaccination), a fever can often occur. Therefore, when given with other childhood vaccines, preventive fever-lowering measures can be considered.
Adult vaccination: Vaccination can be recommended to all adults who want to protect themselves. Vaccination is indicated if there is an increased risk of the disease: in people with certain immunodeficiencies (such as a missing spleen), people who have close contact with meningococcal B patients (e.g. household contacts) and laboratory staff who have come into contact with meningococcal isolates
Vaccination is recommended for staff in pediatric wards, infection departments and intensive care units due to the severity of the disease, even if the risk of the disease is low. You can find detailed information in the current vaccination schedule.
Note For epidemiological reasons, it makes sense to administer the meningococcal B vaccination as early as possible. The age-dependent vaccination schedules for meningococci B must be taken into account. (For more information on the vaccination schedule, see current vaccination schedule).
Child vaccination: The vaccination against meningococcal group C is not included in the free vaccination program. For small children and children from the age of 1 to the age of 10, a single administration of a vaccine against meningococci of group C (MEC-C) is recommended due to the epidemiological situation
Child vaccinations: The one-time vaccination with a quadruple meningococcal vaccine is included in the free vaccination program for schoolchildren between the ages of 10 and 13. MEC-4 for primary immunization in small children is not recommended due to the current epidemiological situation in Austria.
- For children who have not been pre-vaccinated with MEC-C and who have received a tetravalent vaccination (MEC-4) between the ages of 10 and 13 as recommended, a booster vaccination can be considered five years after the initial vaccination with MEC-4 (in appropriate risk situations - e.g. B. at mass events).
- For children who were vaccinated against MenC when they were young, a single vaccination with MEC-4 is recommended from the age of 10 to the age of 19.
- If a vaccination against meningococci C has already been carried out in schoolchildren / adolescent age, an additional vaccination with MEC-4 can be carried out, whereby the usual minimum interval of one month for booster / partial vaccinations should be observed.
Adult vaccination: Adults (people at risk, travel vaccinations) are recommended to receive the conjugated quadruple vaccination once
You can find detailed information in the current vaccination schedule.

\section{Introduction}

The system under consideration comprises of polymers, with uniform monomeric structure, permanently attached to points ${r_\bot= (x_\bot, y_\bot)}$ on a flat 2-dimensional surface. In the literature this system is commonly referred to as a \textit{'tethered polymer layer'} or simply a \textit{'polymer brush'}, however as we shall see a brush is only formed when a certain condition is met.

Polymer layers instil interest in scientists from fields ranging from engineering, chemistry and biology. It is possible to modify the properties of interfaces using polymers, say, by reducing the surface energy of a polymer melt by blending in a polymer of lower surface energy that segregates to the surface \cite{Jones1999}. The FG Nups (long chained proteins) inside the nuclear pore complex, a biogical machine which acts as a selective transport barrier to the nucleus of a cell, can be considered as polymers grafted to the inside of the cylindrical pore. The problem of understanding how this transport barrier arises is then reduced to a problem of how the polymer layer dynamically interacts with transport molecules \cite{Osmanovic2013}.

The field of tethered polymer layers is over 2 decades old and initial scaling theories were provided by \cite{Alexander1977} \cite{DeGennes1980}. Alexander and De Gennes found that the density of the polymer layer, $\rho$, to the normal of the plane was found to have a step-function form. An analytical Self consistent field theory (SCFT) study by Milner, Witten and Cates \cite{Milner1988} consisted of formulating the  partition function $Z_{sc}$ for a single chain in the presence of a mean field $w(r)$ due to the other polymers. The form of this field is not known a priori and as such must be found self-consistently. The partition function $Z_{sc}$ is:

\begin{equation}
Z_{sc} = \Sigma_{{\textbf{r}(s)}} exp(-S_{k})
\end{equation}

where $\textbf{r}(s)$ is the position along the chain at contour label $s$. $S_{k}$ for a configuration $k$ is given by:

\begin{equation}
\label{eq_action}
S_k = \int [ \frac{1}{2} (\frac{d \textbf{r}_{k}(s)}{ds})^2  - w(\textbf{r}(s))]
\end{equation}

which is analogous to the action in quantum mechanics. The partition function, under conditions of strong stretching, is then dominated by configuration(s) which minimize the action. The first term in the integrand of equation \ref{eq_action} is the stretching energy which is analogous to the kinetic energy of a particle. So a strongly stretched configuration can be thought of as a particle with a large momentum and therefore can be handled within the classical limit of quantum mechanics.

Within this regime MWC computed segment density profiles (figure \ref{fig_MWC} ) which had a parabolic form, conflicting the step function prediction given by Alexander and De Gennes.

\begin{figure}[h]

\end{center}
}
\end{figure}
\newpage

The aim here is to outline the implementation of a classical density functional theory (cDFT) scheme to investigate the behaviour of a tethered polymer layer. The theory, computational scheme and results are presented.

\section{Polymer theory}
\subsection{Polymer chains in external fields}

Let the potential energy contribution $U$ due an external field $w$ be given by:

\begin{equation}
U(\lbrace \textbf{r} \rbrace) = k_{B} T \sum_{i=0}^{N} w(\textbf{r}_i)
\label{eq_PE}
\end{equation}

where $\lbrace \textbf{r} \rbrace$ means the set of all positions of $N+1$ monomers, $k_B$ is Boltzmann's constant and $T$ is the temperature. The sum $\sum_{i=0}^{N}$ runs from the first monomer to the last.

In the continuous case where the polymer chain is comprised of infinitely small segments the sum $\sum_{i=0}^{N}$ becomes $\int_0^N ds$. The equilibrium distribution of an ideal chain is given by:

\begin{equation}
\Psi [\textbf{r(s)}] = A \cdot exp(-\frac{3}{2b^2} \int_0^N (\frac{\partial \textbf{r(s)}}{\partial s})^2 ds)
\label{eq_weiner}
\end{equation}

where $A$ is a constant and $b$ is the statistical segment length defined by $\frac{R_e}{\sqrt{N}}$ where $R_e$ is the end-to-end distance of the polymer \cite{Doi1986}. Equation \ref{eq_weiner} is also known as the Weiner distribution. Under an external field it is modified by a Boltzmann factor such that the new conformational distribution function is:

\begin{equation}
\Phi [\textbf{r(s)}] = A \cdot exp(-\frac{3}{2b^2} \int_0^N (\frac{\partial \textbf{r(s)}}{\partial s})^2 ds - \beta \int_0^N w(\textbf{r(s)}) ds)
\label{eq_conf}
\end{equation}

Let $G(\textbf{r}, \textbf{r}^\prime, N)$ be a green's function which represents the likelihood (propagator) that a chain of $N$ steps which started at position \textbf{r} ends at position $\textbf{r}^\prime$. This green's function is defined as:

\begin{equation}
G(\textbf{r},\textbf{r}^\prime,N) = \frac{\int_{\textbf{r}_0 = \textbf{r}}^{\textbf{r}_{N} = \textbf{r}^\prime} \Phi [\textbf{r(s)}] \mathcal{D}[\textbf{r}]}{\int d\textbf{r}^\prime \int_{\textbf{r}_0 = \textbf{r}}^{\textbf{r}_{N} = \textbf{r}^\prime} \Psi [\textbf{r(s)}] \mathcal{D}[\textbf{r}]}
\label{eq_G}
\end{equation}

note the functional measures which denote functional integration since \textbf{r} are explicit functions of the contour label $s$. Therefore the sum over all possible configurations is given by $Z$, the partition function, which is computed by summing over all starting and ending positions for $N+1$ steps as shown in equation \ref{eq_ZG}.

\begin{equation}
Z = \int d\textbf{r} \int d\textbf{r}^\prime G(\textbf{r}, \textbf{r}^\prime, N)
\label{eq_ZG}
\end{equation}

One of the properties of equation \ref{eq_G} is that any statistical weight can be 'built' from a convolution of two statistical weights:

\begin{equation}
G(\textbf{r},\textbf{r}^\prime,N) = \int d\textbf{r}^{\prime \prime} G(\textbf{r},\textbf{r}^{\prime \prime},s) \cdot G(\textbf{r}^{\prime},\textbf{r}^{\prime \prime},N-s)
\end{equation}

where one propagator 'picks' up from where the other left off. This property, which is visualised in figure \ref{fig_propa}, becomes useful when we start computing observables later.

\begin{figure}[h]
\begin{center}
\includegraphics[scale=0.35]{propa}
\caption{ The propagator $G(\textbf{r},\textbf{r}^{\prime \prime},s)$ starts at \textbf{r} for s=0 and ends up at    $\textbf{r}^{\prime \prime}$. The same logic applies to $G(\textbf{r}^{\prime},\textbf{r}^{\prime \prime},N-s)$ but it comes in from the end of the chain. \label{fig_propa}}
\end{center}
\end{figure}
\newpage

Modifying the notation for clarity: $G(\textbf{r}, N)$ is the propagator for a chain of $N+1$ beads to have its end bead at position \textbf{r}. The propagators can be built up recursively via:

\begin{equation}
G(\textbf{r}, s + \Delta s) = \int d\textbf{r}^\prime \Phi[\textbf{r} - \textbf{r}^\prime] G(\textbf{r}^\prime, s)
\label{eq_CK}
\end{equation}

where $\Phi[ \cdots ]$ is given by equation \ref{eq_conf}. Equation \ref{eq_CK} is a Chapman- Kolmogorov equation \cite{Fredrickson2007}  which gives the transitional densities of a Markov sequence, since building the chain as a random walk in the presence of an external disturbance is assumed Markovian.

Taylor expanding the LHS for small $\Delta s$ to $1^{st}$ order and the RHS for small $\Delta \textbf{r} = \textbf{r} - \textbf{r}^\prime$ to $2^{nd}$ order leads to the \textit{forward-Chapman-Kolmogorov} equation:

\begin{equation}
\boxed{\partial_s G(\textbf{r},s) = \frac{b^2}{6} \Laplace G(\textbf{r},s) - w(\textbf{r})G(\textbf{r},s) }
\label{eq_FP}
\end{equation}

where $\Laplace = (\partial_x^2, \partial_y^2, \partial_z^2)$ and $w(\textbf{r})$ is in units of $\frac{1}{k_B T}$. This is analogous to the 'Feynman- Kac' formula in QM and the modified diffusion equation. The only conceptual difference is that time here is in terms of the contour label $s$. The initial condition is $G(\textbf{r}, s=0) = 1$ which means that the probability to go from e.g. \textbf{r} to $\textbf{r}^\prime$ in 0 steps is 1, since trivially $\textbf{r} = \textbf{r}^\prime$.

When there is no external field present the polymer chain is just a random walk whose green's function obeys the diffusion equation:

\begin{equation}
\boxed{\partial_s G(\textbf{r},s) = \frac{b^2}{6} \Laplace G(\textbf{r},s) }
\label{eq_FPideal}
\end{equation}
\newpage
\section{Tethered Polymer System}

For the system under investigation it is assumed polymers are grafted to a square plane with side length $L_{\bot}$ (figure \ref{fig_system}). The length of the system perpendicular to the plane is $L_{z}$ which gives a system volume $V= L_z L_{\bot}^2$. It is forbidden for polymers to penetrate the surface and the former are assumed to be surrounded by implicit solvent, the polymers have no interaction with the surface apart from the impenetrability condition. Polymers have a segment length $b$ of unity and the grafting density of polymers $\sigma$ is defined as the ratio:

\begin{equation}
\sigma= \frac{N_p b^2}{L_\bot^2}
\end{equation}

which assumes uniform grafting within the system. The chains are mono-disperse with $N$ monomers per polymer.

\begin{figure}[h]
\begin{center}
\includegraphics[scale=0.4]{brush_system}
\caption{ Illustration of polymers grafted on plane for $z=0$.\label{fig_system}}
\end{center}
\end{figure}

An important distance in the problem is the distance between grafting points $D=\frac{1}{\sqrt{\sigma}}$. If this distance is less than the Flory radius $R_{F} \approx N^{(\frac{3}{5})}$ it will lead to interactions between the polymers and hence a polymer brush will form. If $D> R_{F}$ the polymers will form small mushroom like configurations (figure \ref{fig_mush} \cite{Jones1999}.

\begin{figure}[h]
\begin{center}
\includegraphics[scale=0.4]{mush}
\caption{ The individual polymers behave as if no other polymers were present for $D>R_{F}$. \label{fig_mush}}
\end{center}
\end{figure}
\newpage

The normalized partition function for a chain grafted at $\textbf{r}_{\bot}$ can be computed by means of

\begin{equation}
Q(\textbf{r}_{\bot}) = \int G({\textbf{r}_{\bot}},\textbf{r},N) d\textbf{r}
\end{equation}

where $G({\textbf{r}_{\bot}},\textbf{r},N)$ is a propagator for a chain of length N that started at $\textbf{r}_\bot$ in the grafting plane and ends at \textbf{r}. This $G_{\textbf{r}_\bot}$ satisfies equation \ref{eq_FP} but with initial condition (IC):

\begin{equation}
G({\textbf{r}_{\bot}},\textbf{r},s=0) = \delta(x - x_\bot) \delta(y - y_\bot) \delta(z - 0)
\end{equation}

 and since the units of a Dirac-delta function are the units of inverse its argument it is easy to see that $G_{\textbf{r}_\bot}$ has units $V^{-1}$. The impenetrability of the grafting surface is imposed as Dirichlet boundary conditions on equation \ref{eq_FP} i.e. $G({\textbf{r}_{\bot}},\textbf{r=r}_{\bot},s)=0$. There seems to be a direct contradiction between our initial condition and our boundary condition, to avoid this the polymers are attached a small distance above the plane at $z=0$ so that $z_{\bot} > 0$. So our conditions on the modified diffusion equation are thus:

\begin{description}
\item[IC:] $G({\textbf{r}_{\bot}},\textbf{r},s=0) = \delta(x - x_\bot) \delta(y - y_\bot) \delta(z - z_\bot)$

\item[BC:] $G({\textbf{r}_{\bot}},(x=x_\bot,y=y_\bot, z=0),s)=0$
\end{description}

The segment density $\rho$ is obtained by functional differentiation of $ln[Q]$ w.r.t the external field $w$ \footnote{It is useful to note that $Q$, $G$ and $\rho$ are all functionals of the external field $w$. Normally this is written as $G(\textbf{r}_\bot, \textbf{r}, N; [w])$ for example but the underlying field dependence isn't explicitly stated here for clarity.}:

\begin{equation}
\rho(\textbf{r}) = - \sigma \int d\textbf{r}_\bot \frac{\delta ln [Q(\textbf{r}_\bot)]}{\delta w(\textbf{r})}
= \int d\textbf{r}_\bot \frac{\sigma}{Q(\textbf{r}_\bot)} \int_0^N ds G({\textbf{r}_{\bot}},\textbf{r},s) G({\textbf{r}^{\prime}},\textbf{r},N-s)
\label{eq_density1}
\end{equation}

where it is clear that the segment density and external field are thermodynamically conjugate variables. $G({\textbf{r}^{\prime}},\textbf{r},s)$ is a complementary propagator that starts from the free end of the chain at $\textbf{r}^\prime$ as illustrated in figure \ref{fig_propa} and is found by solving equation \ref{eq_FP} with \textbf{IC :} $G( \cdots, s=0) =1$.

A more elegant and computationally efficient way to compute the segment density was proposed by Muller \cite{Muller2002}:

\begin{equation}
\rho(\textbf{r}) = \int_0^N ds G_{C}(\textbf{r},s) G(\textbf{r}, N-s)
\label{eq_density_muller}
\end{equation}

where $G_C$ is a propagator with \textbf{IC :}
\begin{equation}
G_C(\textbf{r},s=0)=\frac{\sigma \delta(z-z_\bot)}{G((x,y,z_\bot),N)}
\label{eq_i2}
\end{equation}

which implies that $G(\textbf{r},s)$ is solved first with unity initial conditions and the value of this green's function in the tethering plane is inserted into equation \ref{eq_i2}.

To simplify matters further, the system is laterally symmetric and therefore $\rho(\textbf{r}) \rightarrow \rho(z)$ and $w(\textbf{r}) \rightarrow w(z)$ which means the greens functions themselves are essentially one dimensional. This is made explicit within the machinery since the function $ G((x,y,z_\bot),N)$ is really just a fixed value $G(z_\bot,N)$.
\newpage
\section{Numerical Solution of The Diffusion Equation}

To numerically solve equation \ref{eq_FP}, which is a parabolic partial differential equation, we employ an implicit method of the Crank Nicholson variety which is well known in the literature \cite{Ames1992}.

Taking into account that the system has translational symmetry, i.e. \textbf{r} $\rightarrow$ z, the propagator is then only a function of $z$ and $s$. We denote $\partial_z^2 G$ as $G_{zz}$ and also $\partial_s \rightarrow G_s$ so that, upon discretizing:

\begin{subequations}
\begin{equation}
G_{zz}(s_{k+1},z_j) = \frac{G_{j+1}^{k+1}- 2G_{j}^{k+1} + G_{j-1}^{k+1}}{\Delta z^2}
\label{eq_sub_gzz}
\end{equation}
\begin{equation}
G_s (s_{k+1},z_j)= \frac{G_j^{k+1} - G_j^k}{\Delta s}
\label{eq_sub_gs}
\end{equation}
\end{subequations}

where $k$ and $j$ are discrete time and space labels respectively. Equation \ref{eq_FP} now becomes the discrete Fokker-Plank equation:

\begin{equation}
\frac{G_j^{k+1} - G_j^k}{\Delta s} = \frac{1}{6}(\frac{G_{j+1}^{k+1}- 2G_{j}^{k+1} + G_{j-1}^{k+1}}{\Delta z^2}) - w_j^{k+1} G_j^{k+1}
\label{eq_FPdis}
\end{equation}

which upon rearranging for $G_j^k$ we find:

\begin{equation}
G_j^k = (1 + 2H + \Delta s w_j^{k+1})G_j^{k+1} - H(G_{j+1}^{k+1} + G_{j-1}^{k+1})
\label{eq_gjk}
\end{equation}

for which we have defined $H = \frac{\Delta s}{\Delta z^2 6}$ for simplicity. We need to solve this for $G$ at a later time $k+1$ given that $G^k_j$ is known, this entails solving a tridiagonal linear system of equations. For this process we use the following:

\begin{enumerate}
\item[$\bullet$] $G^k_j = G(z_j, s_k)$ where $z_j = j \Delta z$ for $(j=0, \cdots, n+1)$.
\item[$\bullet$] $\Delta z = \frac{L_z}{n+1}$, $s_k = k \Delta s$ for $(k=0,....,m)$ and $\Delta s =\frac{N}{m}$.
\item[$\bullet$] $N$ is the polymerisation of the chain.
\end{enumerate}

We can show this as a matrix equation (shown here for $j=0,1,2,3,4$):

\begin{equation}
\begin{bmatrix}
(1 + 2H + \Delta s w_1^{k+1}) & -s & 0 \\
-s & (1 + 2H + \Delta s w_2^{k+1}) & -s \\
0 & -s &(1 + 2H + \Delta s w_3^{k+1})
\end{bmatrix} \times
\left(
\begin{array}{c}
G_1^{k+1} \\
G_2^{k+1} \\
G_3^{k+1}
\end{array}
\right) =
\left(
\begin{array}{c}
G_1^{k} \\
G_2^{k} \\
G_3^{k}
\end{array}
\right) +
H
\left(
\begin{array}{c}
G_0^{k+1} = 0 \\
0 \\
G_4^{k+1} = 0
\end{array}
\right)
\label{eq_matrixnum}
\end{equation}

here the vector on the far RHS embodies the boundary conditions which in this case are of Dirichlet type. So finally solving for $G_j^{k+1}$ requires inverting the matrix on the LHS:

\begin{equation}
\boxed{\overline{G}^{k+1}_{j} = [C]^{-1}( \overline{G}^k_j + H \overline{bc})}
\end{equation}

where $[C]$ is the matrix as shown in equation \ref{eq_matrixnum} and bc embodies the boundary conditions. This equation is solved within a loop iterating time, so for each $s$ all the propagators are found which continues until the end of the chain.

The initial conditions are imposed at the first iteration of the time loop. So for the Dirac delta initial condition \ref{eq_i2} we have

\begin{lstlisting}[frame=single]
for( ... ) // loop over all space
{
	if(j*dz == dz)
		{G2 = 1*(N/A)*(1/G1);}
	else;

....
}
\end{lstlisting}

\newpage

The propagator with the unity initial condition is compared to the analytical solution (for the ideal case) in figure \ref{fig_g1compare} to check that the numerical scheme works.

\begin{figure}[h]
\begin{center}
\includegraphics[scale=0.5]{greens_ana_num}
\caption{ The greens function for an ideal chain of length 100 where $L_z = 100$ is compared to the analytical solution. The analytical function sums an infinitie series and here we computed 200 terms hence the spikes towards the boundary conditions. They otherwise match very well. One can now see the relation between this problem and finding the temperature distribution in a rod of length $L_z$.\label{fig_g1compare}}
\end{center}
\end{figure}

Note that the propagators are found for a particular form of the external field $w(z)$. If the whole system is to be solved self- consistently and equilibrium density profiles are to be found, we must employ another scheme which continually updates the mean-field with the segment density and vice versa. We use classical density functional theory to do this which will be outlined in the next section.

\section{Classical Density Functional Theory}

Density functional theory was originally formulated to describe the electronic structure of systems thermodynamically \cite{Kohn1996}. It was later reformulated to apply to classical systems of inhomogeneous fluids \cite{Evans1979}. The essence of a DFT is that the Hamiltonian  $\mathcal{H}$ of a system can be written as an explicit \textit{functional} of the density $\rho(\textbf{r})$. We know that a system is considered to be in thermodynamic equilibrium when the free energy $\mathcal{F}$ is minimized, so the general procedure of a DFT is to carefully 'design' a free energy functional and minimize this w.r.t to the classical density i.e. $\frac{\delta \mathcal{F}[\rho]}{\delta \rho} = 0$. A pedagogical introduction to cDFT is presented here \cite{Jeanmairet2014} as a computational experiment.

The word 'design' is used here because in general the form of $\mathcal{F}$ is not known a priori. Physical assumptions and considerations about the constituents of the system and how they interact with each other and the system boundaries are, essentially, plugged into the free energy. This is done through an excess term $\mathcal{F}_{ex}$ in addition to an ideal term $\mathcal{F}_{id}$ such that $\mathcal{F} = \mathcal{F}_{id} + \mathcal{F}_{ex}$. We now begin to 'design' a free energy functional for our polymeric system. In general the Hamiltonian is of the form:

\begin{equation}
\mathcal{H} = T + \frac{1}{2}  \sum_{j=1}^{N} \sum_{i \neq j}^N \phi( \textbf{r}_i - \textbf{r}_j)
\end{equation}

where $T$ is the kinetic term and $\phi$ is a pair potential, the factor of $\frac{1}{2}$ avoids double counting.

We split the Hamiltonian into two parts $\mathcal{H} = \mathcal{H}_0 + \mathcal{H}_1$ where each term is defined by

\begin{subequations}
\begin{equation}
\mathcal{H}_0 = \sum_{i=1}^N \frac{\textbf{P}_i^2}{2 m_i} + \sum_{i=1}^N w(\textbf{r})
\end{equation}
\begin{equation}
\mathcal{H}_1 = \frac{1}{2} \sum_{j=1}^N \sum_{i \neq j}^N \phi(\textbf{r}_i - \textbf{r}_j) - \sum_{i=1}^N w(\textbf{r})
\end{equation}
\end{subequations}

where the mean field $w$ has units $\frac{1}{k_{B} T}$. We employ the Bogoliubov inequality $\mathcal{F} \leqslant \mathcal{F}_0 + <\mathcal{H}_1>_0$. Where the angular brackets means taking the ensemble average w.r.t to the ensemble of the ideal system. $\mathcal{F}_0 = -k_{B} T ln[Z_0]$ is the free energy of the ideal reference system. Putting things together using the preceding formulas we have

\begin{equation}
\mathcal{F} \leqslant -k_{B} T ln[Z_0] - <\sum_{i=1}^N w(\textbf{r}_i)>_0 + <\frac{1}{2} \sum_{j=1}^N \sum_{i \neq j}^N \phi(\textbf{r}_i - \textbf{r}_j)>_0
\label{eq_FEbra}
\end{equation}

where the $2^{nd}$ and $3^{rd}$ terms are replaced with $\int \rho(\textbf{r}) w(\textbf{r}) d\textbf{r}$ and $\int \rho(\textbf{r}) \rho(\textbf{r}^\prime) \phi(\textbf{r} - \textbf{r}^\prime) d\textbf{r} d\textbf{r}^\prime$ respectively.

We split the pair potential $\phi$ into an attractive and repulsive part. The repulsive part is embodied in an equation of state term known as the Carnahan - Starling equation \cite{Osmanovic2013} which imposes that the beads are hard spheres (HS) and are connected in a chain-like (CC) manner:

\begin{equation}
\begin{matrix}
\mathcal{F}^{CS} = & \int \rho(\textbf{r}) [ \frac{4 \eta (\textbf{r})  - 3\eta (\textbf{r})^2}{[1 - \eta(\textbf{r})]^2} - & (1 -\frac{1}{N}) ln (\frac{2 - \eta(\textbf{r})}{2[1-\eta(\textbf{r})]^3})] d \textbf{r} \\
& \downarrow & \downarrow \\
 & HS & CC
\end{matrix}
\label{eq_CS}
\end{equation}

here $\eta (\textbf{r}) = \frac{\pi d^3}{6} \rho(\textbf{r})$ (d $=$ 1nm) is the packing fraction of spheres in three dimensions. The attractive part of the potential between the beads is modelled as a simple exponential decay of the form:

\begin{equation}
u (\textbf{r}^\prime - \textbf{r}) = - \epsilon \times exp(-\frac{|\textbf{r}^\prime - \textbf{r}| - d}{\lambda})
\label{eq_att}
\end{equation}

for $|\textbf{r}^\prime - \textbf{r}| \geqslant d$ and where $\epsilon= $  the strength and $\lambda= $ the range of the interaction.

We are now ready to explicitly state the mean field free energy of our system for $N_p$ polymers:

\begin{equation}
\boxed{\mathcal{F}_{mf} = - N_p ln[Z_0] + \mathcal{F}^{CS}[\rho(\textbf{r})] - \int \rho(\textbf{r}) w(\textbf{r}) d\textbf{r} + \frac{1}{2} \int \rho(\textbf{r}) \rho(\textbf{r}^\prime) u(\textbf{r} - \textbf{r}^\prime) d\textbf{r} d\textbf{r}^\prime}
\label{eq_Fmf}
\end{equation}

where the density is interpreted as a superposition of bead density profiles of $N_p$ polymers. This is because the problem, tackled in (SCFT), has essentially been reduced to a problem for one polymer in the presence of a mean field. In order to minimize the free energy and ascertain the equilibrium density profile one must continually update the mean field so it is no longer changing meaningfully. This means that the configuration of our system has essentially 'settled down', they are no longer rearranging themselves because they are comfortable in an equilibrium state. Precisely this means that:

\begin{equation}
\partial_t w(\textbf{r}, t) = \delta_\rho \mathcal{F}_{mf} = 0
\label{eq_std}
\end{equation}

where $t$ is a self invoked time variable which has no physical meaning, it represents a stage in an iterative scheme to continually update the mean field. Equation \ref{eq_std} is known as the steepest descent method. Discretizing this we can generate the next mean field by:

\begin{equation}
w^{k+1}(\textbf{r}) = w^{k} + \Delta t[-w^k (\textbf{r}) + (\frac{\delta \mathcal{F}^{CS}[\rho]}{\delta \rho(\textbf{r})})^k + \sum_j \rho^{k}(\textbf{r}^\prime) u(\textbf{r}^\prime - \textbf{r}) \Delta \textbf{r}]
\label{eq_stddis}
\end{equation}
\newpage

where the sum in the last term is over all space. The functional derivative of the HS and CC contributions in equation \ref{eq_stddis} should become larger for increasing density which would decrease the probability to go there. It is useful to check that this term implemented in code behaves and that the derivatives have been performed correctly, one could do this in Mathematica e.g. see figure \ref{fig_mathcomp}.

\begin{figure}[h]
\begin{center}
\includegraphics[scale=0.4]{CS}
\caption{How $\frac{\delta \mathcal{F}^{CS}[\rho]}{\delta \rho(\textbf{r})}$ behaves with increased density for $N=100$ monomers and for $d=1$. \label{fig_mathcomp}}

\begin{center}
\textbf{The Iterative Scheme}
\end{center}

\begin{enumerate}
\item Initially guess $w^0(z)$ is random in space.
\item Numerically solve for the propagator $G$ (unity IC) and then for $G_C$ (see equation \ref{eq_i2}).
\item Compute the density $\rho (z)$ using equation \ref{eq_density_muller}.
\item Update the mean field via equation \ref{eq_stddis} with $\Delta t$ such that the system converges (0.05 here).
\item Check \textbf{IF} $( w^{k+1} - w^k) \leq \gamma$ \footnote{$\gamma << 1$ but should be tailored for each simulation.}\textbf{DO} Finish simulation. \newline
\textbf{ELSE} Go to step 2.
\item Plot results.
\end{enumerate}

\section{Results}

\subsection{Testing the Mean Field}
To check that the mean field scheme is working it is recommended that one tests that the mean fields behaviour makes physical sense. A potential well with increasing depth was tested (figure \ref{fig_well}) to ensure that the monomers become attracted to it, which increases the density in that area.

\begin{figure}[h]
\begin{center}
\includegraphics[scale=0.4]{wells}
\end{center}
\caption{ A square negative potential between $z=10 and z=20$ for increasing well depth. The well starts shallow (red) where there is some attraction, which is increased slightly (green) and at the greatest well depth (blue) the distribution becomes Gaussian. \label{fig_well}}
\end{figure}

We also check that a positive 'hill' mean field leads to the density moving away from that region, which would correspond to an excluded volume interaction. This was tested by increasing the region for a constant mean field towards the grafting plane $z_\bot$ as shown in figure \ref{fig_poswell}.

\begin{figure}[h]
\begin{center}
\includegraphics[scale=0.4]{poswell}
\end{center}
\caption{ A positive mean field encroaches towards the grafting plane which leads to monomers squishing towards the impenetrable surface. \label{fig_poswell}}
\end{figure}

\newpage
\subsection{Investigating Excluded Volume Effects}

The iterative numerical cDFT scheme was used to investigate how the segment density behaves for different diameters ,$d$, of beads. The number of polymers used was 70 for $N=100$ monomers per polymer and the area, $L_\bot$, was chosen such that grafting density is high enough that polymers interact with one another. For the numerical solution of the propagators $\Delta s = 1$ and the spatial grid spacing was tuned as to gain sufficient resolution to keep the code as fast as possible. Figure \ref{fig_results_d} shows plots for increased bead diameter and figure \ref{fig_results_dcon} shows the convergence of the mean field for each simulation run.

\begin{figure}[h]
\begin{center}
\includegraphics[scale=0.5]{density_sigma}
\end{center}
\caption{ The diameter was decreased from the kuhn length in steps of 0.1. The greatest diameter (dark red) and the smallest diameter (dark green). \label{fig_results_d}}
\end{figure}

\begin{figure}[h]
\begin{center}
\includegraphics[scale=0.4]{convergence_sigma}
\end{center}
\caption{ All simulations converged beyond the convergence criterion $\gamma = 0.0001$. \label{fig_results_dcon}}
\end{figure}

The polymerisation $N$ was changed to investigate how it would effect the formation of polymer layers shown in figure \ref{fig_results_N}, the grafting density was shifted for each $N$ to satisfy $D < R_F$.

\begin{figure}[h]
\begin{center}
\includegraphics[scale=0.45]{density_increasingN}
\end{center}
\caption{ Plots for $N$ is 200 (brown), 100 (light blue), 70 (purple), 60 (blue), 40 (green) and 30 (red). For all plots $d = 1$.  \label{fig_results_N}}
\end{figure}

The brush height $h$, which is defined as the maximum $z$ value of the system of polymers, was plotted against polymerisation $N$ which is shown in figure \ref{fig_results_height}.

\newpage
\begin{figure}[h]
\begin{center}
\includegraphics[scale=0.45]{heights_Nm}
\end{center}
\caption{ Heights computed for polymerisation $N$ and a straight line fitted using the Gnuplot software. \label{fig_results_height}}
\end{figure}

\subsection{Discussion}

By either increasing the diameter of the beads or the number of beads per chain one reduces the amount of available space for the beads to move around in. In the presence of excluded volume interactions the polymer chains prefer to extend outwards from the grafting plane which is thermodynamically preferable.

This extending outwards of the chain produces a polymer brush and reducing the excluded volume interactions either by decreasing $d$, increasing $D$ or reducing $N$ leads to the mushroom layer as first shown in figure \ref{fig_mush}. Where the monomers are more densely packed towards the grafting plane.

The brush height $h$ scales linearly with $N$, for $N \geq 60$, which agrees with the scaling argument of Alexander \cite{Jones1999} where $h \approx (\sigma)^{1/3} N $.

Another interesting point of discussion is how the parabolic profile of Milner (figure \ref{fig_MWC}) differs to the results shown here. Already taking into account that the boundary conditions at the surface are implemented differently one must also keep in mind that the SCFT of MWC is for very long chain lengths. Hence at $h_{max}$ the profiles should differ slightly, in fact they should be less abrupt than that of MWC.

I recently purchased a asus k8n mobo and amd 64 3400. After installing win xp, my comp is not able to detect any USB ports. I've looked in the device manager and it says my USB ports are working properly. I looked into my bios setup and my USB is enabled. Also i've tried updating my bios from 1009 to the 1010, but then it gives me error "USB device over current status detected" so then i had to go back to the 1009 version. Another problem that may be related is my sound drivers. Nieither does the onboard nor my Sound blaster live card produce any sound. please help thank you!. if you need any more info just ask.
the last option would to RMA the board.
Try reinstalling the USB drivers that came on the cd with the motherboard.
Life is too short, make the best of it!
You will probabaly have to use Windows Update service to upgrade the USB.
Do unto others exactly what you expect them to do to you.
Yes i have tried uninstalling and reinstalling the USB wit win xp. When i try installin the USB drivers wit the mobo cd it just says win sp1 should install it for you. And my win xp has been upgraded to sp 2. i really hope i dont have to RMA it.
Did you try reseating your mobo? Maybe it's not sitting in the case properly.
Did you move any jumpers when you installed the board.Maybe your missing some jumper's.Or they arent in the right place.Its worth a check. Its also possible that your sound card is dead or bad i had a a-open sound card once that was bad. And make sure the onboard audio is off in the bios when your try to install the sound card.Also you have nvidia audio drivers and realtech.Use the nvidia if you have to use the onboard sound i think they sound better. Also what ports are you using the one's in the front of the case?If so are you sure you hooked them up right?I have a web cam that will only work in 2 or my 6 usb ports.But my Zip drive works in all my USB ports.
Try uninstalling the USB controllers in device manager and reboot. XP should find new hardware and you can run with it from there.
Have you been to Windows Update site yet? What happened?
1) Your USB ports did work before you installed WinXP?
2) You did not make ANY other changes besides installing WinXP before the problem appeared?
4) Have you verified whether +5V is available on the USB outputs?
Have you tried any USB port detection programs like "usbview.exe"? If so, what was the result?
-i tried manually installing usin the file usbochi.sys but for some reason when i click "have disk" in device manager it cannot find it even though i kno i have it.
I do have win xp sp 2 installed and My USB ports have not been working ever since i bought it. Alll the jumpers are correctly placed. Im afraid i mite have to RMA it.
i recommend disconnecting un-nessecary usb devices, if you have external usb ports on your case disconnect the ones you dont use. i had the overcurrent problem and found it was due to the fact i had to many external on exclosure usb sockets connected to the motherboard.
check the resource setting for usb and sound, they might use the same irq and theirfore have a collision.
you can also try the usb drivers that came with the mobo setup cd instead of the win xp drivers.

After a spate in smartphone pickpocketing in Lincoln pubs and clubs, Lincolnshire Police have made a number of successful enquiries.
As previously reported, Lincolnshire Police had reports of around 25 phones being stolen from social venues in the city since February 1.
Since then, an arrest has been made in Manchester regarding the thefts, and a number of phones seized.
Two of the phones were identified as phones stolen from a premises in Lincoln on April 1 and 3.
Lincolnshire Police believe a number of the phones recovered also belong to people in the Lincoln area who did not report their phones as lost of stolen from a venue.
PC Steve Parker is appealing for anyone who has lost or had stolen a phone whilst in a Lincolnpub or club recently contact him if they have not already reported it to the police by email or by phoning/texting 07939 896147.
PC Parker is trying to identify more victims so phones can be returned and the offender further prosecuted.

'The Goldbergs': Wendi McLendon-Covey channels Jennifer Beals in 'Flashdance' homage
Tue, Apr 10th 2018 10:30 pm
'Flashdance' celebrates 35th anniversary
Director Jerry Bruckheimer & Grammy Award-winning singer/songwriter Irene Cara weigh in on film's long-lasting inspiration
Wendi McLendon-Covey, who stars as loving/smothering Beverly Goldberg on ABC's hit comedy, "The Goldbergs," will showcase her dancing skills when she channels Jennifer Beals' role as Alex Owens from the 1980s hit motion picture, "Flashdance," in an all-new episode. The "Flashy Little Flash Dancer" will air Wednesday, April 11 (8 p.m.).
Released on April 15, 1983, "Flashdance" is an American romantic drama directed by Adrian Lyne. It marked the first collaboration between producers Don Simpson and Jerry Bruckheimer. It was a surprise box office success, becoming the third-highest-grossing film of 1983 in the U.S., netting more than $100 million. The soundtrack featured several hit songs, including "Maniac" (performed by Michael Sembello), and the Academy Award-winning "Flashdance ... What A Feeling" (performed by Irene Cara).
"The Goldbergs" is a real-life recreation of executive producer Adam F. Goldberg's experiences of growing up in a suburban family in the 1980s. Like all episodes of "The Goldbergs," the story is inspired by an incredibly real-life experience.
"When my mom was a little girl, she dreamed of being a dancer," Goldberg said. "I even have old 8mm footage of her in dance class. Unfortunately, she never made it as a professional dancer - but it didn't stop her from cutting a rug whenever the opportunity presented itself or watching the classic '80s dance movies like 'Flashdance' over and over. Whenever my mom would dance, we would all laugh hysterically, because she is all skill and little talent. I just had to have Wendi try and do a "Flashdance" number in this episode like my mother would do. It was such a blast when we shot it, especially because Wendi is a gifted dancer in real life."
"I'm a huge fan of the show," said Cara, who won a Grammy Award for Best Female Pop Vocal Performance for "What A Feeling." "I'm really looking forward to seeing this 'Flashdance' moment recreated on 'The Goldbergs.' I'm sure it will be hilariously funny."
"Fun 'Flashdance' tribute on 'The Goldbergs' episode," Bruckheimer said. "Good to know the film still inspires 35 years later!"

Growing up as a Phillies fan in the late 70's was full of heartbreak, and most of it was at the hands of the Los Angeles Dodgers. My very first game that I went to at the ripe old age of five was the NLCS at Veterans Stadium against those same hated Dodgers. That very game helped prepare me for a lifetime of mostly heartbreak brought to me by my beloved Phillies. Today's book takes a look at two of the Dodgers powerhouse teams from that era and in particular the 77 and 78 versions that really stuck it to my Phillies.
Both of these Dodgers teams contained a plethora of homegrown stars. Ron Cey, Bill Russell, Steve Garvey, Davey Lopes are just a few of the players who came up through the Dodger farm system playing for their now Major League manager Tommy Lasorda. It helped foster the environment that the Dodgers always outwardly portrayed, that of being one great big happy family. It created unity and allowed them to play at a level on the field that was matched by very few teams in the league. Its surprising that it took them until 1981 to finally win a World Championship.
The downside of this book for me was being from the other side of the continent I had trouble finding a reason to care about the social activities and politics of Los Angeles. It was a lot of names that someone outside of California would be able to recognize or even care about, but for local readers it still gave a vision of life outside of baseball in L.A. My other gripe about this book is that the author at times puts an autobiographical spin on it. Stories about Dad's hardware store and things like that really just felt out of place with what it seemed the book was trying to accomplish. It almost seemed as if the book had a split personality and the two of them did not work well together. My final gripe is that there were some minor baseball factual errors. This seems to be a recurring problem in baseball books and I wish the publishers would hire a freelancer or someone like that just to fact check some of these things. But that really is more of a pet peeve I guess.
Overall its a good baseball book, just be prepared for it to veer off in other directions every so often. If you can live with that aspect of the book, and you have an interest in the Los Angeles Dodgers, then you will enjoy this book.
As I sit here and recover from surgery, I remember this is the week that my wife and I were going to be crisscrossing the country catching our baseball games at various stadiums. It is somewhat depressing thinking about what could have been, but it is on the back burner for next year and hopefully without any unforeseen issues. The time off recovering has forced me to read more and allowed me to catch up on some of my posts. I have been able to look at some varying topics as of late and found a very interesting, off the beaten path topic for today's book.
Inventing Baseball Heroes takes a look at how the media picks a certain player and uses their skills to fulfill a certain agenda. That agenda is creating hero worship for certain players within the game. This book centers on the early twentieth century and shows how the media helped make certain baseball players household names.
The book is looking at a different time in the world of media. The two main forms at that time were Newspapers and Radio. Through the use if these mediums the writers were able to promote their agendas in making certain players seem larger than life. Their exploits on the field were magnetized to an audience that was looking for new heroes.
The down side to the public looking for heroes was the fact that it allowed journalists of that period to blur the line between fact and fiction. Call it creative license if you want, but it leads me back to the old saying of never let the truth stand in the way of a good story. With reporting being what it was during that time period, you really have to wonder how much of what we accept as truth now is actually accurate.
Amber Roessner does a very nice job of looking at the actions of the media during the formative years of baseball as we all know it. It makes you wonder how much of what we accept as historical fact in the game is actually generated from the imagination of the media. It is something that one can clearly see continuing throughout the history of the game as the generations have passed on.
If you have any interest in the early media coverage of the game you should check this book out. It shows how our game was shaped in the eyes of our society. It also shows to some extent how we as an American society look to our heroes for guidance on how to act in our world.


a cosmopolitan religious and political current. Bahaism spread in the countries of the Near East and Western Europe, the USA, and, to some extent, in tsarist Russia.
It received its name from the nickname of its founder Mirza Husayn Ali Baha'u'llah (literally, "the glory of God"). Bahaism originated in Iraq in the middle of the 19th century as a sect among the Babists who fled from Iran to escape the persecution of the shah's government after the Babist uprisings of 1848–52 were suppressed. The tenets of Baha'u'llah as set forth in his epistles (lawh) and Kitab-i-Aqdas (The Most Holy Book) were intended to replace the Koran and Bayan of the Bab. Baha'u'llah removed the revolutionary and democratic elements from Babism and came out against the revolutionary methods of combating Iranian reaction, while defending private property and social inequality. Bahaism reflected mainly the interests of the Iranian comprador bourgeoisie. It preaches the idea so useful to imperialism of denying national sovereignty, combining science and religion, and so forth. The main centers of Bahaism are in the USA (Illinois) and the Federal Republic of Germany (Stuttgart).
Klimovich, L. I. Islam. Moscow, 1965. Pages 206–11.
In an ironic twist, the only non-Muslims may end up being Shia Iranians themselves who have either re-embraced the pre-Islamic Zoroastrianism, converted to evangelical Christianity or Bahaism.

This author gained some insight into Baha'i views from these particular volumes, as one attentive Baha'i reader had written in his own commentary alongside that offered by missionary Samuel Graham Wilson in his book Bahaism and its Claims (1915).
Wilson hints at these Scripturalists in Bahaism and its Claims, stating that "[s]ome adherents regard Bahaism as Christianity continued.
To a secular Westerner, Iranian Bahaism seems very much a half-way house: a rhetoric containing many progressive ideas, but one designed for traditional folk who cannot do without prophets, hierarchical authority, dreams, signs, and wonders.
However, nowadays there are also among them embraced Islam, Christianity, Buddhism and Bahaism.
The court said that while the Egyptian constitution secures the rights of belief for its citizens, Bahaism was not recognized as an official religion in the country and therefore could not be recorded on official documents.
In Kermanshah, a 70-year-old man was sentenced to 70 lashes and a year in prison for "propagating and spreading Bahaism and the defamation of the pure Imams.
He was tried on 23 April 2007 and charged with "propagating and spreading Bahaism and the defamation of the pure Imams.
Although Bahaism [sic] is not recognized as an official religion but by law Baha'is are entitled to equal rights," wrote Mr.

Sex Education star Emma Mackey has joined the cast of the forthcoming new Barbie movie, and fans could not be more stoked – not least because she'll get to share a billing with her Hollywood doppelgänger.
The movie already has Margot Robbie attached to play the widely-loved doll, with Ryan Gosling serving as her Ken.

Even Will Ferrell is rumoured to be on board as the CEO of a toy company that 'may or may not be Mattel', according to The Hollywood Reporter.
But many fans are even more excited to hear that Mackey will feature in the same world as her lookalike, joking that when she arrives on set with Robbie it'll be exactly like the Spider-Man Pointing at Spider-Man meme.
THR reports that Mackey's specific role has not yet been confirmed, but some people are praying her character will be related to Robbie's, purely to ensure we're capitalising on their uncanny resemblance.
One person tweeted: "I'm obsessed with the fact that we've had like 4 years of 'are Emma Mackey and Margot Robbie the same person' takes that they're going to be in a movie together."
Someone else said: "Emma Mackey and Margot Robbie in a live action barbie movie together THIS IS NOT A DRILL."
A third suggested: "Need Emma Mackey and Margot Robbie to be siblings in Barbie, only fitting."
A fourth added: "Margot Robbie and Emma Mackey definitely playing sisters."

Details of the plot are fairly thin on the ground at this stage, but we do know that Robbie will also be co-producing under her LuckyChap Entertainment production banner, alongside the company's Tom Ackerley, and Robbie Brenner and David Heyman from Mattel.
LuckyChap's Josey McNamara and Mattel's Ynon Kreiz are also on board as executive producers, while the cast also features the likes of Simu Liu, Kate McKinnon, Alexandra Shipp and America Ferrera.
The Warner Bros flick is also being directed by Greta Gerwig, who co-wrote the script with partner Noah Boambach – the duo also being behind such previous films as Greenberg, Frances Ha and Mistress America.
When Robbie was confirmed for the project back in 2019, she said she felt 'honoured' to take on such a well-loved character.
She told Variety: "Playing with Barbie promotes confidence, curiosity and communication throughout a child's journey to self-discovery.
"Over the brand's almost 60 years, Barbie has empowered kids to imagine themselves in aspirational roles from a princess to president.
"I'm so honoured to take on this role and produce a film that I believe will have a tremendously positive impact on children and audiences worldwide.
"I can't imagine better partners than Warner Bros and Mattel to bring this film to the big screen."
She also told British Vogue last year that she was aware of the 'baggage' attached with the role, as it has 'a lot of nostalgic connections.
Robbie added: "But with that come a lot of exciting ways to attack it.
"People generally hear Barbie and think, 'I know what that movie is going to be,' and then they hear that Greta Gerwig is writing and directing it, and they're like, 'Oh, well, maybe I don't...'"
The film is expected to shoot this year, before being released in 2023.
