Blue Lake Rhino
One of the most unusual fossils ever found in the Columbia Plateau is a mold and a few bones of a small rhinoceros. In 1935, a group of hikers found it in a cavity in the vicinity of Blue Lake a few miles south of Dry Falls. This fossil is commonly known as the "Blue Lake Rhino". The mold is preserved in pillow basalt overlying a thin sand bed. Probably the rhino, which was dead at the time, was lying in a small pond and as molten lava flowed into the lake and became chilled somewhat so that the lava did not burn the rhino up. A mold was formed around the dead body. Professional paleontologists have made a coast from the mold and have reconstructed the rhino. Above see a model showing how the animal may have appeared prior to burial. The actual rhinoceros measured about eight feet from snout to tail.

Fingerprint image enhancement is an essential preprocessing step in fingerprint recognition application. There are many authors proposed the different fingerprint enhancement methods. Most present well-known methods are base on Gabor filters. However, the present proposed Gabor filters almost can not be efficient in some cases such as: the local orientation changes rapidly and the fingerprint image is heavily noisy. This paper proposes a novel filter design technique based on the orientation consistency to improve the Gabor filter with the aim that achieves higher efficiency in clarifying the high curvature ridges of the noisy fingerprint images. It is called adaptive orientation consistency-based Gabor filter (AOC-BGF). Actually, this is the technique which tunes adaptively the Gabor filter window size based on analyzing the orientation consistency. The orientation consistency describes how well the orientations over a neighborhood are consistent with the dominant orientation. The performance of the minutiae detection process on the database FVC2004 DB4 shows the effectiveness and superiority of the proposed method.

second per port (0.05% of the traffic). You ask how you can get useful results when you are missing 99.95% of the traffic. In this case, the only number that matters is the number of samples being generated - 11 per second. If your sFlow analyzer is reporting per port traffic information every minute, then the results will be based on a sample size of 660. If you are rolling up traffic for the whole switch, then you have a sample size of 31,600 and if you are monitoring all the switches in your data center you would have a considerably larger sample size. Now consider the types of question you might want to ask, for example how much storage traffic (NFS, iSCSI, FCoE) is being carried on the network. Typically storage traffic will constitute a significant portion of data center traffic, so let's assume that the actual number is 60%. On a per-port basis the sFlow analyzer would produce a result in the range 54-66%. On a per switch basis, the range would be 59.63-60.37%, and finally if you want a data center wide number you would be extremely close to the correct answer. The per-minute answers are usefully more than accurate enough for troubleshooting, congestions management, DDoS analysis etc. For accounting and capacity planning purposes you typically consider longer time period. For example, if you wanted to generate a monthly report based on the single link's data, you would have a sample size of over 28 million, giving an extremely accurate measurement of the traffic.
 The goal with sFlow is to sample as little of the traffic as possible, while still generating acceptable accuracy since this increases the scalability of the overall monitoring system.
 While it's useful to understand the underlying sampling technology, the calculations don't need to be performed manually. A good sFlow analyzer will automatically perform the calculations and present results; sFlowTrend is free, properly scales sFlow, and is a good way to familiarize yourself with sFlow.
 Not all sampling schemes produce accurate results. The sFlow standard specifies a particular scheme that is proven to work. NetFlow and IPFIX allow many types of sampling, many of which produce questionable results and give sampling a bad name.


Quick Answer: What Time Should A 14 Year Old Be Home?
Why do teens sleep late?
This nightly 'sleep debt' leads to chronic sleep deprivation..
How late should a 15 year old stay out?
11pm seems quite late for a 15-year-old, even at weekends. I would set her curfew time a little earlier than that, and then you can reward her for sticking to it by extending it a bit in a few months.
Can a minor be out past curfew?
It is unlawful for any minor under the age of 18 years to remain in any public place, or any private business open to the public, between the hours of 10:00 p.m. on any day and sunrise of the immediately following day; provided, however, that the provisions of this section shall not apply when: A.

Why do teens lie?
When should a 13 year old go to bed?
They typically go to bed between 7 p.m. and 9 p.m. and wake up between 6 a.m. and 8 a.m. Children at this age typically go to bed between 7 p.m. and 9 p.m. and wake up around 6 a.m. and 8 a.m., just as they did when they were younger.
How late should a teenager stay out?
Some parents prefer a set curfew, while others prefer to vary curfew decisions by the circumstances: One night 10:30 makes sense; another night, midnight is acceptable. Flexibility encourages a teen to demonstrate responsibility in exchange for expanded privileges.

For details of the survey refer to:
Wilkes Station on Clark Peninsula was built by the United States in 1957 and Australia took custody of the station in 1959.
Wilkes Station is now almost permanently frozen in ice and is only occasionally revealed during a big thaw every four or five years. Many objects remain embedded in the ice.
The condition of the buildings has deteriorated since the site was abandoned in 1969 and repairs are necessary for the survival of the structures. What remains at Wilkes are a number of barracks buildings known as 'Clements' huts, and the remnants of the semi-cylindrical canvas store buildings known as 'Jamesway' huts.
More heritage/archaeological surveys are required for a more complete understanding.

Generally, possession of an illegal substance with the intent to distribute is a serious crime and often results in more serious consequences than drug possession for personal use. However, in Pennsylvania, you can also be charged with drug delivery resulting in death, which is perhaps the most serious drug charge of all. Drug delivery resulting in death can result in a sentence of up to 40 years in prison and is classified as a felony.
Two Pennsylvania men were recently charged with possession with intent to deliver drugs and criminal use of a communication device, and are also facing a pending charge of drug delivery resulting in death. These charges apparently stemmed from a drug overdose that occurred over the July 4th weekend.
If you have been charged with drug delivery resulting in death, prosecutors will have to establish that you intentionally gave someone and drug and that they died as a result of using the drug. However, this crime can often be difficult for prosecutors to prove as it is hard to establish that the drugs given to them in fact contributed to the person's death. This law was implemented to reduce the number of overdoses and drug crimes, but some argue that it has not served that purpose.
Pennsylvania courts often impose strict penalties for drug distribution, particularly if someone is killed because of that distribution. A criminal defense attorney can help defend you against these serious charges and minimize the penalties you face if you are convicted. Remember that the burden of proof is on the prosecutor, meaning that it is their job to prove your guilt beyond a reasonable doubt to get a conviction.

JTU Institute for Education and Culture
09 July 2009
The Japan Teachers' Union (JTU) is the oldest and largest union for teachers in Japan. NFER was commissioned by the JTU to undertake a comparative study of England, Scotland and Finland's working teachers practice. The JTU compared the workload conditions of teachers in England and Scotland to those in Japan, in order to advocate for change to policies on Japanese teachers' working conditions. The aim was to see how good working conditions affected academic performance.
The NFER approached a sample of headteachers, deputy headteachers, assistant headteachers and class teachers across England and Scotland, who were asked various questions about their working life. Finland was of interest because of its high pupil academic attainment, and England due to its compulsory national curriculum testing. Schools in Scotland were approached because of their similarity to English schools but without compulsory national testing. Representatives from the JTU also visited four schools in England and Scotland to observe working conditions and practices for themselves.
The report contains comparisons of the following:
- hours worked
- time preparing for class
- perceptions of teacher tasks
- pressures associated with changes to education policy
- attitudes of student\families
- difficulties with taking breaks and days-off.
This summary report is a fascinating insight into the differences in teachers' working conditions across four countries.

President Dr. Arif Alvi has called for adopting modern farming techniques to increase the agricultural productivity so to meet the country's food requirements. He also underlined the need to promote latest technological and IT tools to ensure the availability of agricultural inputs to farmers and reduce the cost of production. The President expressed these views during a meeting with a delegation of farmers at Governor house. Federal Minister for National Food Security and Research, Syed Fakhar Imam, Punjab Food Minister, Hamid Yar Hiraj, and agriculturalists from Punjab, Khyber Pakhtunkhwa and Sindh attended the meeting.
The farmers apprised the president about the issues related to input costs, subsidies and support price of different crops. Addressing the meeting, the president stated that the government was focusing on uplifting farmers as the prosperity of agriculture sector was directly linked with the socioeconomic development of the country. He added that incentives had been offered to support farmers and reduce their cost of production which had given a major boost to agricultural yield of major crops during the last year.

Here are two striking and (I think) attractive Blechnum hard ferns.
Nigrum is Latin for black. Colenso's hard fern is named after William Colenso – printer, missionary, politician, and naturalist – altogether a very extraordinary person. Biography of William Colenso. The "hard" part of the name comes, I presume, from the texture of the frond; most species are fairly rough and almost leathery.
Both Colenso's hard fern and the black hard fern are found in wet, shaded, and usually cold habitats. The above photographs were taken along the Mangahao Makahike Track near Levin. Although at a relatively low altitude, it nevertheless provides good conditions for these species.
Blechnum is one of the biggest fern genera in New Zealand, with 18 indigenous species. They are easily recognised because almost all have dimorphic (different looking) fertile and sterile fronds. The fertile fronds, which make the spores, have much thinner segments and are black or nearly so. They are also often held up above the sterile fronds.
The following are some of the more common species in New Zealand.

Weather data for nautical information system
In Lemwerder, Germany at the Weser River, wind direction and speed are measured and transferred in 60 second intervals via the OTT netDL 1000. The data is transmitted, wireless, over a distance of 600 meters to the radar tower in Ritzenbuettel, where it is integrated into the ship traffic network - the Authority for Water and Navigation (WSA), Bremen. The WSA is also responsible for monitoring the traffic network for safety conditions.
Each hour, a status report including the current water levels, weather reports, visibility range and important incidents in the area is sent out to assist navigating the waters. Since 2013, the system has been providing valid data, without any gaps for over two years.
Data loggers for remote data collection & long term monitoring
The versatile OTT netDL 500 and 1000 data loggers were developed specifically for use in hydrology and meteorology stations. In addition to recording data, the loggers are extremely low power and offer flexible data transfer options via the internet and mobile networks, providing a logging and telemetry solution for every project.

Unique Acoustic System Protects Manatees From Injuries And Death [ScienceDaily 2008-06-11]
[Photo] Manatees live in shallow, calm rivers, estuaries, saltwater bays, canals, and coastal areas. They move from fresh to salt water easily and the Florida manatee frequents most areas of Florida. It is estimated that there are approximately 3,000 Florida manatees in existence today. (Credit: Image courtesy of Florida Atlantic University)
ScienceDaily (Jun. 11, 2008) — Researchers at Harbor Branch Oceanographic Institute at Florida Atlantic University have developed and improved upon a unique acoustic system designed to keep manatees from being injured or killed by flood gates and boat locks. Locks are used on sections of a canal or river that may be closed off by gates to control the water level to enable the raising and lowering of boats passing through.
The "Manatee Acoustic Detection Sensor Protection System" is composed of an array of unique acoustic transmitters and receivers that provide non-contact detection of manatees as they pass through the gates of the lock. When a manatee blocks the acoustic beams, which they cannot hear, the gates stop and remain open long enough to allow them to pass through safely. Harbor Branch recently received a $5.8 million federal contract from the U.S. Army Corps of Engineers to install the system in southern Florida on the six navigation locks around Lake Okeechobee. Among these are Moore Haven lock at Clewiston and the Port Mayaca lock where the St. Lucie River meets Lake Okeechobee, a waterway that links the Atlantic Ocean to the Gulf of Mexico.
Engineers at Harbor Branch designed manatee protective pressure systems more than a decade ago for canal lift gates used by the South Florida Water Management District. Last summer, the Harbor Branch manatee protection team installed the system on the Ortona Lock on the Caloosahatchee River which is part of the Okeechobee Waterway System operated by the U.S. Army Corps of Engineers. The Corps wanted a new system for lock gates that swing open too fast and sent out a public request for bids for replacement—Harbor Branch's high frequency sound system won.
"This summer we'll be entering into phase 2 of the second year of this important project and we will begin assisting with the installation of the devices at six locks in Lake Okeechobee," said Larry Taylor, project manager for manatee protection systems at Harbor Branch. "We installed the prototype acoustic system about ten years ago in the St. Lucie lock. Since then, we have redesigned the system with underwater sensor cartridges. The device is now smaller, cheaper, faster and easier to operate."
Aside from watercraft collisions, the highest incidence of human-caused mortality to manatees is due to entrapment in floodgates and canal locks. According to the Florida Fish and Wildlife Conservation Commission, locks or gates caused at least 191 manatee deaths statewide since 1974. Manatees live in shallow, calm rivers, estuaries, saltwater bays, canals, and coastal areas. They move from fresh to salt water easily and the Florida manatee frequents most areas of Florida. It is estimated that there are approximately 3,000 Florida manatees in existence today.


Let $f(x)$ and $g(x)$ be irreducible polynomials over rationals. I know that to find the density of the primes $p$ such that (say) $f(x)$ has a root mod $p$ can be found using Chebotarev density theorem, looking at the density of elements with fixed points in the Galois group of $f(x)$. (Thinking of the Galois group embedded in $S_d$, where d is the degree of $f$) I was wondering what is the general way of doing this when we're given two polynomials $f$ and $g$, and if we try to find the density of primes such that both $f$ and $g$ have roots mod $p$. Should we somehow look at the compositum of the splitting fields of $f$ and $g$? That's my feeling, but I don't know how to do that. Thanks.
 - $\begingroup$ @ R. van Dobben de Bruyn : That's slightly different. There, it finds density of primes which are split in the Galois closure, but prime doesn't necessarily have to split for these polynomials to have root mod $p$, so that answer only gives lower bound for the density. $\endgroup$ – vgmath Jul 12 '17 at 20:56
 - $\begingroup$ Aren't the two events independent? $\endgroup$ – Igor Rivin Jul 13 '17 at 0:42
 - $\begingroup$ _USER_: you're right, it's not the same question. I retracted my close vote. (For the record, the other question.) $\endgroup$ – R. van Dobben de Bruyn Jul 13 '17 at 16:24
Let $P(h)$ be the proportion of primes $p$ such that the monic polynomial $h(t)$ has a root mod $p.$ You say that you can compute this when $h$ is irreducible. Your question is equivalent to asking if you can do it when $h$ is a product of two irreducibles:
You ask about finding $x,$ the proportion of primes where $f$ and $g$ both have roots. But $P(f)+P(g)=P(fg)+x.$
 - 1
 $\begingroup$ I am not sure I understand why this answers the question, since Chebotarev only applies to irreducibles, I believe )(and _USER_ says as much). $\endgroup$ – Igor Rivin Jul 13 '17 at 4:09
 - $\begingroup$ It doesn't answer the question. But it does show it equivalent to a presumably hard problem: generalize Chebatorev to non-irreducibles (or at least those with two factors.) So something like computing two splitting fields $F,G$ and their composite $FG$ is not going to solve the given problem unless it solves the harder one. $\endgroup$ – Aaron Meyerowitz Jul 13 '17 at 4:58
 - $\begingroup$ _USER_ Meyerowitz, @ Igor Rivin : Sorry for my ignorance if I'm wrong, but I couldn't see why Chebatorev requires irreduciblity? Doesn't it work for splitting field of any polynomial? Is there any quick counter example when it doesn't work? $\endgroup$ – vgmath Jul 19 '17 at 1:26

In Ubuntu (and any other Ubuntu-based distro), when you use a "sudo" command, the system will prompt you for your password. After the first "sudo" command, the system will remember your password for the next 15 minutes so you don't have to enter any more password for subsequent "sudo" command. If, however, you feel that the 15 minutes is a bit too long/short, here is how you can change it.
1. Open a terminal and type:
2. In the file that open, scroll down till you see the line:
Change it to
Defaults env_reset, timestamp_timeout=X
where X is the time (in minutes) that the sudo password will timeout. You can set X to the value you want.
- If you set X to "-1", it will revoke the password prompt, which is not advisable.
- If you set X to "0", the system will prompt you for password everytime you use the "sudo" command
3. Press "Ctrl + x" to exit. Don't forget to press "y" to save the changes.


Binocular Rivalry
Binocular rivalry is a visual phenomenon that occurs when the eyes (or visual perception) alternately switch between two different images that are being presented to the eyes - particularly images that are being presented together in the form of optical illusions. All of us have probably seen these, most commonly as black and white images that can appear to be different pictures depending on how you look at them. For instance, the Rubin vase image is an example of binocular rivalry. Your visual perception switches from seeing a vase to seeing two people looking at one another.

The long-held theory that early human ancestors in East Asia crafted their tools from bamboo and wood is much more complicated than originally conceived, according to a new study.
Research until now has failed to address a fundamental question: Is it even possible to make complex bamboo tools with simple stone tools?
Now an experimental archaeological study — in which a modern-day flint knapper replicated the crafting of bamboo knives — confirms that it is possible to make a variety of bamboo tools with the simplest stone tools.
However, rather than confirming the long-held "bamboo hypothesis," the new research shows there's more to the theory, says archaeologist Metin I. Eren, the expert knapper who crafted the tools for the study.

Big Bumblebees Memorize Locations of the Most Rewarding Flowers
They perform learning flights to study their surroundings.

Sometimes size matters. Bigger bumblebees spend time learning the locations of the most nectar-rich flowers, so they can easily find them again, new research finds. In contrast, smaller bees aren't quite as picky.
After drinking from a flower, bumblebees decide if it's worth visiting again. Then they perform what are known as learning flights to study the location around the flowers.
"If the flower is rich in nectar, a bee will be very keen to return and therefore invest in learning its location," study co-author Natalie Hempel de Ibarra, associate professor at the University of Exeter's Centre for Research in Animal Behaviour, tells Treehugger.
Bumblebees will slowly fly around the flower, then fly away from it, looking back at its location. It will memorize the flower and the views all around it. On its next trip, the bee matches what it sees with the views it already memorized. This takes it back to the flower's location.
"We have found that larger-sized bumblebee foragers are not only more likely to perform a learning flight when they find a rich flower as compared to a low-rewarding flower, but also to hover around the flower for longer. This in turn allows them to look back more at the flower and to memorise it better," Hempel de Ibarra says.
"This investment in the learning flight pays off during subsequent foraging flights where the bee can shorten its travel time and go directly to the locations of the best-rewarding flowers."
Smaller bumblebees do the same thing but aren't as choosy in their flower selection.
"They also conduct learning flights when departing from a flower on which they obtained a nectar reward," Hempel de Ibarra says.
"We find that in contrast to the large bees they readily accept lower and higher rewards and are less selective when investing in the learning flight. They spread their efforts more evenly."
Watching Bees at Work
For the study, researchers set up an experiment in a greenhouse where they could watch captive bees visit artificial flowers containing varying concentrations of sugar solutions. A downward-facing camera captured the bees' learning flights. The recordings included the bees, the flowers, and cylinders that marked the flowers' positions.
The flowers had sugar solutions ranging from 10% to 50% sucrose. When the concentration was greater, the larger bees spent more time circling the flowers and making learning flights. When the concentration was smaller, the length of time the bees spent looking at the flower and flying around it tended to drop.
Smaller bees spent the same amount of effort learning where the flowers were, no matter whether the concentration of sucrose was low or high.
The contrast likely reflects the different roles of the bees in their colonies, the researchers said.
"Large bumblebees are able to carry larger loads and explore further from the nest than smaller ones. Small ones with a smaller flight range and carrying capacity cannot afford to be as selective and so accept a wider range of flowers," the researchers concluded in the study, published in the journal Current Biology.
Small bees are often involved with more tasks inside the nest, only going out to forage if necessary when food supplies are running low, says Hempel de Ibarra.
Benefits of Bees of All Sizes
Having both large and small bees foraging means they cover more ground and serve different purposes.
"Big bees can cover a larger area and find higher-rewarding flowers further away. Investing in flower learning and using its navigational capabilities a bee can identify the most effective travel route for its foraging trips," says Hempel de Ibarra.
"Smaller bees, however, do not travel far away, and they should focus on the area closer to the nest. They can return to the nest more easily without having to invest as much in navigation. Discriminating less between flower rewards, allows smaller bees to fill up the crop more quickly."
Bumblebees aren't the only insects that perform these learning trips. Honeybees and wasps also make learning flights and ants are known to perform learning walks.
"Learning flights are an important behaviour that is displayed by each individual forager bee," says Hempel de Ibarra. "Understanding them can tell us a little more about which flowers bees like to visit."

In ABAP OVERLAY statement is used for overlaying the characters of string on another string. Overlayed string characters will be replaced by the other string characters according to the position.
Dont be confused, you will get more idea after seeing one examples.
- Take two strings,
- Command for OVERLAY is "OVERLAY string1 WITH string2."
- After this, string1 will becomes 12345F.
- The first 5 characters of string1 have replaced by the string2.
- string1=A B C D E F
- string2=12 3 4 5
- After the command OVERLAY string1 WITH string2.
- string1 will becomes 12B3C4D5
- Each character is replaced with the characters of string2 as per the position.
- In this example blank spaces of string1 also replaced.
If we need to replace only characters ( not blank spaces ),we need to used an additional parameter "ONLY str" with OVERLAY statement.
The complete syntax will be :
OVERLAY string1 WITH string2 [ONLY str].


MM Blog: Footstep Generated Power
Here's a look at a flooring system installation that can create sustainable energy.
Mnet 173082 Hero 0
We've seen people discuss harnessing the power of the wind, the ocean and the sun – but what about something as simple as walking? A company called Pavegen decided to test this theory by creating floor tiles that generate electricity through footsteps. It's based on the concept of kinetic energy – you expel energy as each foot hits the ground, and rather than disappearing or becoming useless, it is translated into usable, storable energy.
The newest generation of the company's tiles, named the V3, is triangular, allowing more productivity by providing a generator in each corner. The V3 generates five watts of power while someone walks across it. Although that doesn't sound like much, it's more than 200 times more efficient than the company's first prototype. Since its beginning in 2009, Pavegen has delivered more than 100 installations for a variety of sectors, including public transportation stations, malls, airports and other various public spaces.
How could this form of energy be utilized in a manufacturing setting? How could this technology be expanded into other uses?

World Health: the intellectual history of a twentieth century idea
World health is currently understood in a commonsense way as an objective pursued by the World Health Organization. Yet world health is also an idea with a complicated and unexpected twentieth century history.
- How and why did the idea of world health arise? How did nineteenth century public health framed nationally become twentieth century population health, framed globally?
- What were the intellectual traditions formulating 'world health' and 'global population' as problems, projects and possibilities in the twentieth century?
These are the research questions driving this intellectual history of the contested and changing concept of world health. The project focuses on the period between the establishment of the League of Nations Health Organization in 1923 and the Bucharest World Population Conference in 1974, which was designated World Population Year.
The overarching aim is to establish and explore the biopolitical nature of world health as a crucial aspect of twentieth century globalisation.

Why does NT Factor® help reduce fatigue when other means do not?
The reason NT Factor® helps when no other nutritional or drug regimen does on a reproducible basis is as follows: All nutrients have cellular antioxidant capability. The principal action of antioxidants is to protect cell and mitochondrial membrane from free radical attack. However, in the already compromised individual typical nutrients have limited capacity to work effectively. NT Factor® introduces the ability to restore cell membrane health and nourish healthy cell membrane and mitochondria membrane thereby setting the stage for better utilization of moderately dosed nutrients while at the same time inhibiting cancer cells. NT Factor® does not contain any amount of any one or combination of nutrients that would interfere with treatments. Nutrients that support rapidly dividing cells (the type of cell that chemotherapy targets) are held to an absolute minimum such as vitamin C and folic acid.

virtualspecies is a freely available package for R designed to generate virtual species distributions, a procedure increasingly used in ecology to improve species distribution models. This package combines the existing methodological approaches with the objective of generating virtual species distributions with increased ecological realism. The package includes 1) generating the probability of occurrence of a virtual species from a spatial set of environmental conditions (i.e. environmental suitability), with two different approaches; 2) converting the environmental suitability into presence-absence with a probabilistic approach; 3) introducing dispersal limitations in the realised virtual species distributions and 4) sampling occurrences with different biases in the sampling procedure. The package was designed to be extremely flexible, to allow users to simulate their own defined species-environment relationships, as well as to provide a fine control over every simulation parameter. The package also includes a function to generate random virtual species distributions. We provide a simple example in this paper showing how increasing ecological realism of the virtual species impacts the predictive performance of species distribution models. We expect that this new package will be valuable to researchers willing to test techniques and protocols of species distribution models as well as various biogeographical hypotheses.

Women in the Iranian city of Khorramabad are dressed for the ceremony of Chehel Manbar. The commemoration of the battle of Karbala, when Hussein, a grandson of the Prophet Muhammad, was killed, is one of the most important ceremonies of the year for Shia Muslims.
On the ninth day of the Muslim month of Muharram—on the eve of the climactic Day of Ashura—women in some regions participate in Chehel Manbar. In an act of mourning for Hussein they go veiled and barefoot to light candles at forty different locations.
Ceremonies differ from city to city, according to regional traditions. In Khorramabad, women light candles in the doorways of houses and offer cookies to the occupants. They may also cover their head and shoulders with clay in an act of mourning.

Penang State Museum and Art Gallery Officially open in 1962, the Museum houses a fine collection of old photographs, maps, charts and other historical relics. There are also Malay daggers (keris), Chinese furniture, embroidery and paintings of old Penang. At the Penang State Museum there are also interesting sections which recounts the bloody nine days of rioting between Chinese secret societies in 1867, attributed by bewildered British authorities to a rambutan-throwing incident. Georgetown suffered a near civil war before the administrators took a firm hand. The societies were heavily fined and the proceeds used to build police stations which subsequently kept the peace. The Penang State Art Gallery on the other hand is situated at a different premise which is at Dewan Sri Pinang, Light Street, a stone thrown away from the Museum premise. There are two Art Galleries which is situated in Dewan Sri Pinang. The Art Gallery on the Ground floor displays the works of local artists and is the venue for special exhibitions meanwhile the exhibition hall at the 3rd Floor housed the Permanent Collection which comprises of paintings donated or bought from the artists.

Accounting Information Gathering System for Grid Environment
Grid computing represents the fundamental computing shift from a localized resource computing model to a fully-distributed virtual organization with shared resources. Accounting is one of the main obstacles to widespread adoption of the grid. Accounting has until recently, been a sparsely-addressed problem, particularly in practice. In this paper, we design and implement the accounting information gathering system. Implemented system is based on OGSA, following GSAX framework of RUS-WG in GGF. And the schema of gathered and serviced accounting information is following Usage Record Fields of UR-WG in GGF. Also, the accounting information integrating and monitoring tool for system management in the grid environment are implemented.

How should an employer calculate a term-time worker's paid holiday?
There is no specific legislation setting out how to calculate holiday pay for term-time workers. Employers must ensure that the paid holiday of term-time workers is not less favourable than that of full-time workers (as this would be unlawful under the Part-time Workers (Prevention of Less Favourable Treatment) Regulations 2000 (SI 2000/1551)). Employers must also ensure that term-time workers receive at least the statutory minimum entitlement of 5.6 weeks' paid annual leave a year. The employer can designate periods during the school holidays to be the term-time worker's annual leave and pay holiday pay in instalments over the year.
Where a term-time worker has regular hours during term time and their salary is paid in equal instalments over the year, to ensure that they are receiving the minimum statutory paid holiday, the employer can add 5.6 weeks on to the number of weeks the employee is contracted to work during the year, before averaging their pay out into equal instalments. For example, for an employee who is contracted to work 39 weeks a year, the pay that is averaged over the year must be based on at least 44.6 weeks of work.
For term-time workers without regular hours, the employer can still pay holiday pay in instalments over the year (for example, monthly or at the end of each term) ensuring that it amounts to at least 5.6 weeks' pay. In Harpur Trust v Brazel IRLR 1012 CA, the Court of Appeal held that the holiday entitlement of term-time workers should not be pro rated to that of full-year workers. The calculation of a week's pay for term-time workers with irregular hours should be based on the average hours worked during the 12 weeks before the calculation date, not counting weeks in which no pay was due (s.224 of the Employment Rights Act 1996).
Term-time workers are entitled to 5.6 weeks' paid holiday, even if this works out more favourably than comparable full-time workers when calculated as a proportion of the actual number of days worked during the year.
In Harpur Trust, the employer had based its holiday pay calculation on 12.07% of the employee's hours each term, following Acas guidance relating to casual workers. This was found to result in the employee receiving less than 5.6 weeks' holiday per year.

The data that's analyzed by seismologists following a large earthquake is usually the record of a catastrophe — it typically means something really bad has just happened. But what if you could take this data and turn it into something beautiful instead? That's the thinking of designer James Boock who has rigged together an elaborate paint-globbing mechanism that uses seismic wave data to generate colorful abstract images. The end result is one-half geology, one-half art.
It's called the Quakescape 3D Fabricator and its construction was inspired after a major quake hit Christchurch, New Zealand last year. It works by taking earthquake data from the site GeoNet and converts it into a series of visual patterns.
The canvas is a moulded, topographical landscape that's shaped like a real section from Christchurch. The colors, which are ejected from a series of hanging cartridges, represent the magnitude of the seismic waves.
Boock put this together with the help of Josh Newsome-White, Brooke Bowers, Hannah Warren, George Redmond, Richie Stewart and Philippa Shipley.

- Print factsheet
Montane reed frog description
Like many frogs within its genus, Hyperolius castaneus displays remarkable variation in appearance (3) (4). The smooth skin of this species is consistently yellow to red underneath, but the colouration and patterning on the back varies considerably. Some have green backs with numerous diffuse dark spots, while others have brown backs, occasionally flecked with black spots. In addition, some forms have an irregular lateral line, running along the side of the body and varying from light to dark (2). Equipped with fairly long limbs and large toe pads, many Hyperolius species are adept climbers (4) (5).Top
Montane reed frog biology
Along with many other species in the genus, Hyperolius castaneus is yet to be the subject of a comprehensive study. However, this nocturnal species is particularly noted for its gliding ability (7). In the wet season the reed frogs tend to gather near water, preferably smaller temporary water bodies, where they breed. However, very little is known of their whereabouts outside the breeding season (8). Most, if not all, Hyperolius species from forest habitats deposit eggs in a gelatinous mass on vegetation above water, while some savanna-living species lay their eggs aquatically (5) (8).Top
Montane reed frog range
Hyperolius castaneus is found in the Albertine Rift, one of the richest sites for biodiversity in Africa. Its range stretches through eastern Democratic Republic of Congo, western Rwanda, western Burundi, and south-western Uganda (1) (6).Top
Montane reed frog habitat
Inhabits swamps in grassland and forest, between 1,600 and 2,850 metres above sea level (1).Top
Montane reed frog status
Classified as Vulnerable (VU) on the IUCN Red List (1).Top
Montane reed frog threats
Although a relatively abundant species, the distribution of Hyperolius castaneus is severely fragmented and its population is probably declining because of a decrease in the quality and extent of swamp habitat. Habitat conversion for agriculture and encroaching human settlement are thought to be principally responsible for habitat degradation in the Albertine Rift (1)Top
Montane reed frog conservation
There are no known conservation measures for Hyperolius castaneus but it is known to be present in at least two protected areas, Bwindi National Park in Uganda and the Virungas National Park in the Democratic Republic of Congo (1).Top

New Mexico State Flag
The State Flag of New Mexico has a modern interpretation of an ancient symbol of a sun design as seen on a late 19th century water jar from Zia Pueblo. This pueblo is thought to have been one of the Seven Golden Cities of Cibola, which explorer Vasquez de Coronado sought. The red sun symbol was then called a "Zia" and is shown on a field of gold. The red and gold are the colors of Queen Isabela of Castile that the Spanish Conquistadors brought to the New World.
The flags of Spain, the Republic of Mexico, the Confederate States of America, and the United States of America have all flown over the "Land of Enchantment" during the long history of the state.

Unseen Tears: A Documentary on Boarding School Survivors
Native American families in Western New York continue to feel the impact of Thomas Indian School and Mohawk Institute, also known as the Mush Hole, — Native American boarding schools where "savage-born" children were, in the words of Richard Henry Pratt, trained in "civilized language and habit".
"Unseen Tears", a documentary produced by Native American Community Services, features boarding school survivors, who talk openly about the tragic separation from their families, abuse, and a systematic assault on their language and culture:
"We had all our hair cut off, we were made bald," - says Sally General, a Mohawk Institute survivor. "Kids on the reservation used to call us Mush Hole baldies."
"When we used our language, they would wash our mouths with soap. They would throw us into a cold shower and beat us along the way," notes Elliot Tallchief, who was sent to Thomas Indian School when he was five years old.
The documentary also highlights the efforts made in local communities to heal the wounds and break the cycle of intergenerational trauma resulting from the boarding school experience.

I just blogged that beet seeds are actually seed pods so when you plant what you think is one beet seed you actually plant a cluster of seeds. If more than one seed germinates from the cluster, you get two or more plants with very tangled seeds. Dividing them is difficult from cell packs. It can be done. Beets are very hardy and if the weather is cool, a damaged plant can survive. A damaged plant is typically a plant with like a single strand of root.

|Beet Root Cluster - The Rusted Garden: Gary Pilarchik|
Even the roots of beets are red. This cluster is several beets. Tear from the bottom until you reach the leave and plant cluster. Make a wish a break the best you can.

This is Part 1 of a multi-part entry into the process and pains of the creation of JPL's map of Isla Sorna. Eventually these entries will be merged into one article and made part of the Encyclopedia.
Jurassic Park Legacy's map of Isla Sorna (aka Site B) has been a many-years long endeavor. Numerous maps of Isla Sorna exist, both in-film props and real world publicity items. One would therefore think that it would be a simple thing to create a map corresponding to the films' events.
However, none of the maps work together, and topography varies from one map to another. It seems the production team for the films did not have any sort of concrete map or topography from which they were working from.
This leaves JPL's Map Team with a dilemma. Which of these many maps should be used as the de facto topography for our map? Should we rule out every other map or attempt to merge all the maps together? Should one map be considered more likely to be "accurate" than all the others?
After a lot of deliberation it was agreed that the map seen in The Lost World: Jurassic Park during Kelly's wandering of the trailers (below) was the most accurate for our purposes. The topography is clear, the map is given a central focus in the film (even if only for a few seconds), and within the film universe itself it appears to be a detailed map of the variety you would find pinned in a government building.
So our topography was established; now we had to determine the size of the island. This was done fairly easily. Costa Rica appears on this map as well, and sizing it appropriately allowed us to determine the size of Sorna. The result; approximately 21 x 20 miles.
The island was now complete. We created a large topographical map of the entire Las Cinco Muertes island chain and created a map scale from there (at our scale; 116 pixels per mile). Work on actual locations could now finally begin.
Continued in Part 2…

SAO/NASA ADS -> Help -> The ADS Data
|SAO/NASA ADS Help Pages||Prev | Next|
1.2 - About the Data in the ADS
The main body of data in the ADS consists of bibliographic records, which are searchable through our Abstract Service query forms, and full-text scans of much of the astronomical literature which can be browsed though our Browse Service
1.2.1 - Origin
The abstracts database contains data from many different sources. The initial dataset was from NASA's Scientific and Technical Information group (STI) and covered the years _PHONE_. After that, we began collecting data directly from the journals as agreements were reached with them individually. In addition, we have collected references from SIMBAD, NED, conference editors, and individual authors. We have created electronic records from table of contents of most journals and conference series back to volume 1 as we have scanned them in order to provide complete bibliographic coverage.
All bibliographic records include an Origin field which details where a given abstract came from. In cases where we have the same paper from multiple sources, we currently list them in the order above, but will soon merge the information into one complete record. It should be noted that we no longer receive data from STI, but that those abstracts in the system from STI are rewritten versions of the original author abstract. Our list of origins includes information on where some of our data come from.
Click on our Journal Abbreviation List to see a full list of journals and their abbreviations.
The full-text scans available in the ADS can be browsed through the ADS Browse Service. The scans were created by digitizing printed issues of astronomical publications. For more information on the full-text archive, please see the Scanned Literature help page.
Many articles that are not scanned in the ADS may be ordered from the Center for Aerospace Information (CASI).
Many of the dissertation citations contained in the ADS are published with the permission of ProQuest LLC. Further reproduction is prohibited without permission. Copies of dissertations may be obtained by Telephone (800) _PHONE_ Web page: _URL_
The abstract databases contain records from hundreds of publications, colloquia, symposia, proceedings, and internal NASA reports. These sources cover diverse loosely astronomy-related subjects, ranging from Electrical Engineering through Optics to Particle Physics. They include the larger American astronomical journals: Astronomical Journal, Astrophysical Journal, Icarus, Publications of the Astronomical Society of the Pacific, etc, as well as many Non-American journals: Astronomy & Astrophysics, Monthly Notices of the Royal Astronomical Society, Publications of the Astronomical Societ of Japan / Australia / India, Astrophysical Journal of the Soviet Union / Australia / Ireland, etc., as well as more general interest journals such as Science, New Scientist, Nature, Mercury, Sky and Telescope, etc.. Complete coverage is only guaranteed for those journals we have scanned and placed online. That information is listed on our article service page.
1.2.3 - Bibliographic Identifiers
Creating unique Bibliographic codes (bibcodes from here on) allows us to identify literature in our database. Using a standard bibliographic format, as explained below, we can easily identify different bibliographic records and users can efficiently search for them.
The bibliographic code is a 19 digit identifier which describes the journal article. The format was originally adopted by the SIMBAD and NED projects, and follows the syntax:
A list of journal abbreviations already in use is available on-line. Here are some abbreviations for the most popular Journals:
ApJ: Astrophysical Journal ApJS: Astrophysical Journal Supplements ApJ: Astrophysical Journal Letters (with an L in the Qualifier position). AJ: Astronomical Journal A&A: Astronomy & Astrophysics A&AS: Astronomy & Astrophysics Supplements MNRAS: Monthly Notices of the Royal Astronomical Society PASP: Publications of the Astronomical Society of the Pacific PASA: Publications of the Astronomical Society of Australia PASAu: Proceedings of the Astronomical Society of Australia PASJ: Publications of the Astronomical Society of JapanIn order to accommodate conference proceedings and technical reports, the ADS has modified the original bibliographic code definition in order to present identifiers which are easily recognizable to the user. Conference proceedings, books, colloquia, workshops, and reports in the ADS typically contain a four letter word in the volume field such as conf, book, coll, work, or rept; all other type of proceedings use the identifier proc. For these bibliographic codes, the journal field typically consists of the first letter from important words in the title (e.g. ioda.book for ''Information and On-Line Data in Astronomy'').
Several oddities exist for bibcodes which do not fit into this paradigm. PhD theses, for example, contain a counter in lieu of a page number to distinguish between those written during the same year by authors whose surnames start with the same letter.
Physical Review bibcodes began using an 6-digit id number in the late 1990's instead of a page number. For these articles, we have converted the first 2-digits of the id (which correspond to the issue number) into a lower-case letter in the 14th column. We then use the remaining 4 digits in the page number field.
For conference abstracts submitted by the editors of a proceedings prior to publication, we often do not have page numbers. In this case, we use a counter in lieu of a page number and use an "E" (for Electronic) in the fourteenth column, the qualifier for publication. If these conference abstracts are then published, their bibliographic codes are replaced by a bibliographic code complete with page number. If the conference abstracts are published only on-line, they retain their electronic bibliographic code with its "E" and counter number.
We have created two separate interfaces to assist our users and collaborators in searching and verifying the existence of records in our databases:
Updates to our databases are performed approximately every week, then mirrored to all of our mirror sites. Therefore, any new information added or change made to the databases does not become available immediately; rather it may take up to a week to become active. Corrections are always welcome, for example misspellings, missing pages/scans, broken links, etc. We also encourage you to submit original author abstracts to us through our _URL_ Abstract Submission Form.

Scale factor is the ratio of the length of the scale drawing to the corresponding length of the original object.
We are told to find the scale factor when we are given the original and new dimension of an object. The formula for questions like these are : Original dimension(x) = New dimension. X is equal to the unknown scale factor. In this first example, we are told to find the scale factor and the original dimension is 2", while the new dimension is 1/8". Using the formula we just learned, we can find the unknown scale factor by plugging in the numbers into the formula. The equation becomes 2x = 1/8. To get 'x' by itself, also known as isolating the variable, we divide 2 by 2 and 1/8 ÷ 2, which is 1/16. We discover that x = 1/16. This isn't our final answer. Scale factors are written as ratios, so the final answer could be written as 1/16 : 1 or 1:16.
In this final example, we are told to find the new dimension when we are given the original dimension and scale factor. The formula used to solve this question is : Original dimension • First number in scale factor = New dimension. The original dimension is 1/8" and the scale factor is 2:1. We multiply 1/8 · 2, which equals 2/8 and when simplified, 1/4. The answer is 1/4"

Direct oceanic emissions unlikely to account for the missing source of atmospheric carbonyl sulfide
Abstract. The climate active trace-gas carbonyl sulfide (OCS) is the most abundant sulfur gas in the atmosphere. A missing source in its atmospheric budget is currently suggested, resulting from an upward revision of the vegetation sink. Tropical oceanic emissions have been proposed to close the resulting gap in the atmospheric budget. We present a bottom-up approach including (i) new observations of OCS in surface waters of the tropical Atlantic, Pacific and Indian oceans and (ii) a further improved global box model to show that direct OCS emissions are unlikely to account for the missing source. The box model suggests an undersaturation of the surface water with respect to OCS integrated over the entire tropical ocean area and, further, global annual direct emissions of OCS well below that suggested by top-down estimates. In addition, we discuss the potential of indirect emission from CS2 and dimethylsulfide (DMS) to account for the gap in the atmospheric budget. This bottom-up estimate of oceanic emissions has implications for using OCS as a proxy for global terrestrial CO2 uptake, which is currently impeded by the inadequate quantification of atmospheric OCS sources and sinks.

The story of the capture of the British ship Margaretta by a group of Patriots in Machias on June 12, 1755 has taken on legendary proportions, some of them deserved, some exaggerated to improve the story and to move Machias more toward the center of the Revolutionary War narrative.
Lt. William Burrows and Commander Samuel Blyth, commanders of the USS Enterprise and the HMS Boxer, led their ships and crews in Battle in Muscongus Bay on Sept. 5, 1813. The American ship was victorious, but both captains were killed. Portland staged a large and regal joint burial.
Britain was especially interested in occupying Maine during the Colonial era to take advantage of the timber resources. The tall, straight, old growth white pines were perfect for ships' masts to help supply the growing Royal Navy.

The evidence-adjustment factor
With our prior beliefs represented as probability equations, let's get back to computing that evidence adjustment.
(evidence adjustment) = P(H|S∧K) / P(H|K)
The numerator on the right-hand side we already know: P(H|S∧K) = 1.
The denominator, P(H|K), we do not. We must find some way to break it into terms that we do know.
The nice thing about propositions, like H, is that we can use Boolean logic to manipulate them. So, let's break H into pieces that are more likely to be useful:
H = H∧(S ∨ ¬S) = (H∧S) ∨ (H∧¬S).
What I did was split the proposition that the coin comes up heads into a disjunction of two mutually exclusive propositions: that the coin comes up heads and is special, or that the coin comes up heads and is not special. That first term of the disjunction, however, is redundant: if a coin is special, our prior knowledge already tells us that it must come up heads; therefore, we can simplify H∧S to S. Now we have,
H = S ∨ (H∧¬S), given K,
P(H|K) = P((S ∨ (H∧¬S))|K).
We can break up the disjunction on the right-hand side using the sum rule for probabilities, which is given as:
P(A∨B) = P(A) + P(B) – P(A∧B).
Since our disjunction is of mutually exclusive propositions, the final term of the sum-rule expansion drops out; therefore,
P(H|K) = P(S|K) + P(H∧¬S|K).
Now let's crack that new final term, P(H∧¬S|K). To do so, we'll use the product rule for probabilities:
P(A∧B) = P(A|B) P(B) = P(B|A) P(A).
P(H∧¬S|K) = P(H|¬S∧K) P(¬S|K).
And, already knowing that P(H|¬S∧K) = 1/2, we can simplify the right-hand side:
P(H∧¬S|K) = P(¬S|K)/2.
And substituting this reduction back into the equation for P(H|K) gives,
P(H|K) = P(S|K) + P(¬S|K)/2.
We can further simplify the equation by noting that P(S|K) + P(¬S|K) must equal 1 and, therefore, that the ¬S term can be rewritten in terms of S to give,
P(H|K) = P(S|K) + (1 - P(S|K))/2 = (1 + P(S|K)) / 2.
Now, to bring it all home, let's plug these values into our evidence-adjustment formula:
= P(H|S∧K) / P(H|K)
= 1 / P(H|K)
= 1 / [(1 + P(S|K)) / 2]
= 2 / (1 + P(S|K)).
And that's our evidence-adjustment factor. Now, what does it do?
Adjusting our beliefs in light of the new evidence
To better understand what the evidence adjustment does, let's recall the original belief-adjustment equation:
(new plausibility) = (old plausibility) × (evidence adjustment)
So the adjustment factor nudges our initial degree of belief, whatever it may be, one way or the other, depending on the evidence. To see the effect of this nudge for various initial degrees of belief, consider the following plot:
Looking at the plot, let's see if the nudge agrees with our intuition. First, if we were absolutely convinced that the coin is (or is not) special, no amount of evidence should sway our beliefs. Looking at the plot, we see that when our prior probability is 0 or 1, so is our adjusted (posterior) probability, exactly what we expected.
But what if our initial knowledge is complete ignorance about the coin being special? In that case, upon seeing the coin toss, our prior probability of 1/2 gets nudged to the posterior probability of 2/3 – toward the belief that the coin is indeed special. Again, it's what we would expect.
In fact, the evidence adjustment is always going to push us toward confirming the belief that the coin is special because the evidence supports that belief. The force of that push, however, depends on how surprising we find the evidence, that is, how much it challenges our prior beliefs. The following plot shows this relationship:
Note that the evidence provides the strongest push – a factor of 2 – when our prior knowledge makes us doubt most strongly that the coin is special. On the other extreme, when we are already convinced that the coin is special, observing that the coin comes up heads when tossed isn't surprising at all, and correspondingly the evidential push of that observation is nothing: an adjustment factor of unity.
Answering the original question
Finally, with our evidence adjustment well in hand, we can answer the original question: After seeing the outcome of this single coin toss, how much more should you believe my claim that the coin always comes up heads, compared to what you believed before the coin toss?
The answer, we reasoned earlier, is the evidence adjustment less one:
(relative plausibility increase)
= [evidence adjustment] – 1
= [2 / (1 + P(S|K))] – 1
= [2 / (1 + (prior plausibility))] – 1
= (1 – (prior plausibility)) / (1 + (prior plausibility))).
So, if we let p represent our prior degree of belief that the coin is a special, heads-always coin, we should be
100% × (1 – p) / (1 + p)
more confident in our belief after seeing the coin come up heads when tossed.
And that's the answer.
But there are other ways of arriving at it. One of the more convenient is to use odds instead of probabilities. But let's save that discussion for next time.
Update: Here's the promised discussion: Odds and the evidence of a single coin toss.

Biological distances calculated between archeologically recovered human skeletal collections are often used to assess the effects of temporal and spatial distance on subpopulation divergence. Although there are many previous empirical studies that examine skeletal material arrayed across time and/or space, the theoretical expectations for temporally or spatially related variation in biological characteristics have not been formally developed. In this paper I present the infinite island model, the unidimensional stepping-stone model, and the migration matrix method in forms that allow prediction of the genetic distance between groups separated by a given spatial and temporal lag. These models demonstrate that, if there is isolation by geographic distance, then the correlation between genetic and spatial distance (controlling for temporal distance) should be positive and the correlation between genetic and temporal distance (controlling for spatial distance) should be negative. I use observations of nonmetric traits in a sample of prehistoric crania from west-central Illinois to demonstrate the expected relationships among biological, temporal, and spatial distance. The results indicate that, once the effects of temporal trend are removed, biological and spatial distance are positively correlated and biological and temporal distance negatively correlated within this sample.

An innovative process that converts low-energy longwave photons (light particles) into higher-energy shortwave photons has been developed by a team of researchers at the Max Planck Institute for Polymer Research in Mainz and at the Sony Materials Science Laboratory in Stuttgart. With the skillful combination of two light-active substances, the scientists have, for the first time, manipulated normal light, such as sunlight, to combine the energy in photons with particular wavelengths (Physical Review Letters, October 4, 2006). This has previously only been achieved with a similar process using high-energy density laser light. The successful outcome of this process could lay the foundation for a new generation of more efficient solar cells.
