Letter: Proctor responds on Sauls' column

Published Thursday, March 18, 2004
Editor: This is in regard to Mr. Walter Sauls' recent letter. In his enthusiasm for the proposed legislation, Mr. Sauls neglects to mention that the legislation does not remedy a significant problem addressed in the audit - the fact that the school was required to pay prices in excess of appraised values for properties in the Genoply-Alfred Streets block. These costs were approximately $819,127 above the original estimate and approximately $384,288 above the appraised values, which appear to have increased as the properties were acquired. These expenditures represent the only documented waste of state funds.
In his opposition to granting the school eminent domain power, Mr. Sauls fails to explain why FSDB, an institution that serves some of the state's students with the most severe disabilities, is to be denied the same authority granted school districts, community colleges, and state universities. Initially, one might conclude that the restriction on the future expansion of the school was no more than the appeasement of several of the nearby neighbors. Such a conclusion, however, does not explain with the staff director of the Joint Legislative Auditing Committee, when explaining why the school did not have eminent domain power, presented the rationale that district school boards were elected. The implication of this statement is that, because FSDB's trustees were appointed, the school did not have eminent domain authority. The explanation, however, is flawed in that both community college and state university boards are appointed.
Thus one is compelled to consider the possibility that there may be those who once again entertain the notion of dividing, moving, or duplicating FSDB elsewhere in the state. To impose the requirement of an inter-local agreement upon the school, while denying it eminent domain powers, is essentially the same as capping its enrollment and restricting its expansion. It is difficult to comprehend why such an action would be taken at a time when we are told that advances in medical science virtually ensure the survival of more children with multiple disabilities.
Now, as to Mr. Sauls' "warning:" He is correct in that I have no administrative authority as regards the school; however, as a member of the state Board of Education, I have a responsibility to the school, which I shall exercise with or without Mr. Sauls' approval.
As to my past leadership on the board of trustees of FSDB, Rep. Wiles is quoted as having said that the school is a "leader in educating students with special needs" and as having also said, "In many ways the school is a model for other similar schools across the nation." I am grateful for and concur with the representative's assessment.

For a transaction to take place between a client and a server, a conversation must be established. A conversation is established when a client makes a request by broadcasting a service name and topic name, and a server responds. Transactions can then take place across the conversation. When no more transactions are to be made, the conversation is terminated.
The following list identifies the elements involved with client/server activity:
A conversation is established when a server responds to a client.
A service name is a string broadcast by a client hoping to establish a conversation with a server that recognizes the service name. The service name is usually clearly related to the server application name.
The topic name identifies what the conversation between client and server is to be about. For example, it could be the name of a file that is open in the server application. Each topic is attached to one particular server. A server can have many topics.
The item usually identifies an element of the file identified by the topic which should be read (in the case of a request) or written to (in the case of a poke). For example, it might refer to a cell in a spreadsheet document.

Spouse: Victor Egan
Father: Umrao Singh Sher-Gil Majithia
Mother: Marie Antoniette Gottesmann
Sibling: Indira Sundaram
Often referred to as India's Frida Kahlo for aesthetically blending traditional and Western art forms, Amrita Sher-Gil was one of the most famous painters of India. She is also considered as a revolutionary woman artist and the originator of modern art in India. Though her artworks mainly depicted Western style and culture during the initial stages of her career, the painter gradually began to rediscover herself by depicting Indian subjects using traditional methods. Apart from painting, she was also well-versed in playing piano and fond of reading. She even travelled to different parts of India, France and Turkey and managed to incorporate ideas gained from different techniques into her own works. Throughout her career, she painted her friends, lovers and also made quite a few self-portraits, for which she is often considered as a narcissistic by many.
Amrita Sher-Gil was born on 30th January, 1913 in Budapest, Hungary. Her father, Umrao Singh Sher-Gil Majithia, was a Persian and Sanskrit scholar, while her mother, Marie Antoniette Gottesmann, was a Hungarian singer. Amrita grew up with her younger sister Indira Sundaram and was very fond of her. She spent her initial childhood in the Dunaharaszti town of Hungary and developed an interest towards painting at a very young age. By the time she was five, Amrita had started painting. In the year 1921, her family shifted from Hungary to the beautiful hill station of Shimla, due to financial crisis. After landing in Shimla, the nine year old Amrita started learning piano and also acted in plays along with her sister at the famous Gaiety Theatre. As a young girl, she had rebellious thoughts and was once expelled from her school for embracing atheism.
Amrita started to learn the nuances of painting at the tender of eight. Initially, she trained under Major Whitmarsh and later under Beven Pateman. In 1923, when she was 10 years old, her mother Marie came across an Italian sculptor living in Shimla. When the sculptor moved back to Italy in 1924, Amrita and her mother followed suit. After reaching Italy, she joined Santa Annunziata, a famous art school in Florence. While at Santa Annunziata, Amrita was exposed to the works of Italian artists, which furthered her interest in painting. After a few months of learning, she returned to India.
In 1926, Amrita's nephew and Indologist Ervin Baktay visited Shimla and played a crucial role in constraining her to take up painting seriously. Aware of her amazing potential, Ervin was probably her first critic and pushed her to do better. Amrita started off by painting her servants and maids and they became her initial subjects. When she was 16 years old, her mother took her to Paris, which was considered as the hub of modern art. In Paris, Amrita started to train under Pierre Vaillent and Lucien Simon at Grande Chaumiere and also received formal training at the École des Beaux-Arts. During her stay in Paris, she was greatly influenced by European painters like Paul Cézanne and Paul Gauguin. She also started working under Lucien Simon, with whom she had trained earlier, and he was highly appreciated for her works.
During the initial stages of her career, Amrita's works deeply reflected her Western influence and her technique was similar to the paintings that were practiced in the Bohemian circles. While in Paris, she came up with a number of paintings depicting her own life in Paris. She often used her friends as her subjects and also ended up with a series of self-portraits. Around this time, she created 'Young Girls', which gained wide recognition and appreciation. Judging by the rich colors that she often used in her paintings, one of her professors predicted that her works would make more sense in the East rather than the West. Her professor's wish soon came true as she returned to India after experiencing a sudden longing to head back to India.
Amrita Sher-Gil returned to India in the year 1934 and began her never-ending journey of trying to decode the traditions of Indian art. She was influenced by the Mughal as well as the Ajanta paintings. In 1937, she began her journey to the southern parts India and was deeply moved by the plight of many villagers and unprivileged people. This started reflecting in her works and eventually gave rise to paintings such as 'Brahmacharis', 'Bride's Toilet' and 'South Indian Villagers Going to Market'. Her technique and style was now nowhere similar to the paintings that she came up with in Paris. Amrita had learnt to incorporate Indian traditions in her works and thus had rediscovered her purpose and style of painting. She even wrote to one of her friends, saying that Europe belonged to the likes of Picasso and Matisse while India belongs to her.
Works in India
Her works in India, post her wedding, had a tremendous impact on Indian art in the following years. Many of her works were influenced by the works of Rabindranath Tagore and Abanindranath Tagore. Among her works during this phase of her life, the best ones were 'Siesta', 'Village Scene' and 'In the Ladies' Enclosure', all of which represented the poor state of the unprivileged and women in the country. Though her works were celebrated by critics, they seldom found buyers. In 1941, she moved to Lahore (undivided India), where art was being appreciated at that time. There she came up with marvelous paintings such as 'The Bride', 'Tahitian', 'Red Brick House' and 'Hill Scene'.
Achievements and Recognition
Amrita Sher-Gil was one of the most impressive as well as the most gifted Indian artists of the pre-colonial era. She was also the youngest as well as the only Asian artist to be elected as an Associate of the Grand Salon in Paris. For her work 'Young Girls', she was awarded with a gold medal in Paris, which was considered as a prestigious award there. The works of Amrita Sher-Gil have been declared as National Art Treasures by the Government of India. Most of her paintings adorn the National Gallery of Modern Art in New Delhi. Though her paintings were largely unsold while she was alive, they fetched impressive amount of money later on, making her one of the priciest Indian women painters of all-time. In 2006, 'Village Scene' sold for a whopping 6.9 crore rupees in New Delhi. Back then, it was the highest amount paid for any Indian painting in India.
AmritaSher-Gil was a free spirit and led a pretty carefree life. She had numerous relationships and was bisexual. She portrayed many of her boyfriends and girlfriends throughout her career. She was a good friend of Jawaharlal Nehru, but never painted him, terming him as "too good looking" to be painted. She, however, exchanged multiple letters with Nehru. She went through at least two abortions prior to her wedding. The abortions were performed by Dr. Victor Egan, her Hungarian first cousin, who later married her in 1938. Thereafter, she moved with her husband to her paternal family's home in Gorakhpur city of Uttar Pradesh.
Amrita left this world in the year 1941, aged 28 after a serious illness which made her to slip into coma. Though the real reason for her death was never ascertained, it was said that a failed abortion could have caused her demise. Her mother accused her husband Dr. Victor Egan, saying that he murdered her. She was laid to rest at Lahore on December 7, 1941.
Amrita Sher-Gil is often considered as the pioneer of modern art in the country as her works influenced and inspired a number of modern day greats. India Post released a stamp of her painting 'Hill Women' in the year 1978. There is a road named after the painter in Lutyen's Delhi, known as the Amrita Shergil Marg. Budapest's Indian cultural center has been named after her. In 2013, the 100th anniversary of her birth was declared as the international year of Amrita Sher-Gil by UNESCO. Many plays and novels including Salman Rushdie's 'The Moor's Last Sigh' were inspired by her.

Howard Goodall's Story of Music
Don't miss the first episode of Howard Goodall's landmark series
Howard Goodall presents a personal view of the history of music, from the beginning of human existence to the present day.
In the first episode of a six-part series Goodall explores mankind's earliest steps in music-making, suggesting that it is an integral part of human existence.
Archeological evidence shows that music could have been as much a part of everyday life in the Upper Paleolithic Age as it is today.
The episode goes on to look at Gregorian Chant and developments in medieval music that provided a foundation for the rules of harmony and notation that we still use today. Find out more on the BBC website.

Building ontology is one of key issues for knowledge sharing which is important technology to realize largescale knowledge-base systems. In this paper, we propose a computational framework for constructive ontologies called aspect. We first formalize aspect in a logical framework and then define it as a programming language. Aspect is representation of conceptualization which consists of a vocabulary and a theory, and ontologies are built as composition of aspects. Two types of composition of aspects are provided, one is combination of aspects which is just union of aspects, and the other is category of aspects which links different but domainsharing aspects. Using them, we can represent not only relations among different aspects but also a set of aspects which either of them can be used if needed. We show a logical formalization of aspect by using modal logic. Category aspect is modeled using modal operator O. We also formalize characteristics for aspects like compatible and rigid which can be used as criteria for ontology. We also provide ASPECTO1, a programming language for aspect by extending Ontolingua. We then show translation of messages as a way of interpreting multiple aspects. A translation agent can translate a message with some aspect to one with another aspect by analyzing dependency of aspects. Mediation and translation of messages are important to build agents easily and naturally because less knowledge on other agents is requested for each agent.

Industry associations and social media in wind energy
In the modern era, social media is one of the most useful tools for businesses to share their message, build brand identity, and reach completely new target groups. Industry associations can complement this by representing the goals and concerns of a sector. This also applies to wind energy and could be a key driver of future expansion.
Social media use is growing year on year. In fact, it is estimated that over 45% of the global population is active on social media. Enterprises now realize that if they are not present on these channels, they could be missing out priceless exposure and opportunities for business growth. There is plenty of potential for the wind energy sector. By increasing its online presence, wind energy can strengthen its position as a leading and viable source of green electricity, combat the rise in "fake news," and promote the latest technologies.
Providing exposure to the things that matter
The power of social media doesn't lie in the fact that it offers people information, more that it engages people and brings them into a discussion. There is no doubt that a widespread shift away from conventional power sources, which have been in use for decades, requires action from the population. Without a way to reach the general public and not only specialists or professionals already involved in the sector, it is harder to set the wheels in motion for this change.
Giving the wind energy sector a collective voice
Industry associations, such as WindEurope, the Chinese Wind Energy Association, the Global Wind Energy Council, the American Wind Energy Association (AWEA) and many more represent the interests of the wind energy sector in different regions. These associations are usually comprised of members from different states or countries that assist the sector in various ways. Their activities include hosting events, lobbying, influencing legal policy, and acting as a united voice for businesses. Combating fake news and providing credible and accessible information is a key aim for associations.
A potential obstacle for wind energy?
Even though social media has the potential to highlight wind energy as a viable source of green electricity, it can also create new challenges. In the same way that individuals can promote wind energy, people can also put common negative myths in the spotlight – such as wind turbine noise causing cancer or power shutdowns occurring when there is no wind. Additionally, to stay competitive on social media, wind energy companies will need to be very active online. This means investing time and money into creating interesting and engaging social media content.
Nonetheless, despite possible obstacles, the benefits of social media outweigh the drawbacks. Online channels enable companies and personalities in the wind energy sector to connect with the public like never before. Enhanced by the important work of industry associations, the wind energy industry can make its mark as a collective and promote the cause of economical, sustainable electricity.

Chickens as big as horses
The British novelist H.G. Wells did not like to have his science fiction novels likened to those of the French writer Jules Verne, but there are some similarities. And even more than Verne's pieces, the work of Wells more than a century ago often contains weird echoes of much more recent events.
One of his stories is about a machine of war that startlingly resembles the tank that was developed during World War I, though Wells wrote about it more than a decade before the start of that conflict.
A novel entitled "The Food of the Gods" has some things that sound even more recent. A chemist named Bensington teams up with a professor named Redwood whose specialty is growth of animals and plants. Redwood has determined that growth comes in spurts, with periods of inaction coming in between while the individual accumulates a new supply of whatever it is that causes growth. Bensington finds that he may have hit upon a substance that would obviate those periods of inaction.
Bensington, though rather fussy and absent-minded, has the task of locating a farm where chicks can be fed the special food, which they call Herakleophorbia, after Herakles, the Greek legendary strong man.
Several combinations of the food have no effect on the chicks, and the scientists aren't aware that the couple hired to manage the farm have been very careless in the manner in which they handle the food, spilling it and leaving containers open to invasion by animals such as wasps.
Finally a substance is developed that seems to have the desired effect. Bensington finds chicks that are extra large and has one killed to take back to show to Redwood. There it is — still covered with the fuzzy yellow down common to baby chicks, but as large as a grown hen.
Redwood becomes thoughtful as he looks at the animal because he has fed some of the food to his baby son. The way the two scientists talk about what's likely to happen carries the same tone as that used by the scientists who had just watched the first atomic bomb test explosion in the New Mexico desert.
The first unusual event comes with the wasps. They emerge from a nest near the farm where the food is located and are as big as hawks. One disrupts a picnic, and another causes a panic when it flies through a skylight into the British Museum. Their stingers are three or four inches long.
An even more startling turn of events is when giant rats, as big as tigers, make their appearance in the countryside. By this time the food has become known to the public and has been nicknamed Boomfood. Bensington is interviewed by journalists who quote him as saying anything they want him to say. The doctor who has been tending Redwood's growing son tries to ascertain the chemistry of the food and in the process spills even more of it.
The chicks, meanwhile, grow into hens and escape from their farm pen. Each is as big as a horse, and they bring consternation to a nearby village when they come clucking down the main street. Then there's a swamp where some of the food has been washed. Water bugs, which usually are less than a half-inch in length as adults, turn up as big as lobsters, to the detriment of a naturalist who has reached into the water after some giant algae.
One of the careless doctor's patients is a princess who is related to the royal family. She is kept isolated as she grows, but as the years go by, young Redwood happens upon the field where she is concealed. He is 35 feet tall, and she is 20 feet tall. In his eyes she is a mere wisp of a girl, and in her eyes he cuts a manly figure. So it is love at first sight.
The thing about Boomfood is that it has an effect only upon things in their growth stage. If an adult who has stopped growing takes some of it, there is no effect and the growing things stop growing when they reach normal adulthood.
As is customary with human nature, a movement arises that opposes giantism. "Bigness" they call it, and they make a point of praising that which is small. But there are some who promote "bigness," and the language Wells gives his characters in the debate on that subject has an eerie resemblance to the debate over the Vermont Yankee nuclear power plant and the proposals for wind farms on mountaintops.
Yet Wells wrote the novel in 1905 and 1906, decades before those controversies arose. The mark on his genius as a science fiction writer was to display his characters with a sense of reality.

Question 1. Let $R$ be a polynomial ring over a field $k$. Assume that $R$ is graded in the usual way (i.e., each variable has degree $1$). Let $I$ and $J$ be two ideals of $R$ such that $I$ is generated in degree $\leq a$ (that is, there is a set of generators of $I$ that have degrees $\leq a$) and $J$ is generated in degree $\leq b$. Is it true that the ideal $I \cap J$ is generated in degree $\leq a+b$?
When $R$ is a univariate polynomial ring, this is simply claiming that the lcm of two polynomials of degrees $\leq a$ and $\leq b$ is a polynomial of degree $\leq a+b$; of course this is correct. But this kind of logic does not generalize to more variables. (It is easy to see that Question 1 has a positive answer when $I$ and $J$ are monomial ideals.)
If true, Question 1 would give a new (inductive) proof for the following theorem (part of the Subspace arrangement theorem of Derksen and Sidman -- see Theorem 2.1 in their A sharp bound for the Castelnuovo-Mumford regularity of subspace arrangements, arXiv:math/0109035v1):
Theorem 2. Let $R$ be a polynomial ring over a field $k$. Assume that $R$ is graded in the usual way (i.e., each variable has degree $1$). Let $I_1, I_2, \ldots, I_t$ be $t$ homogeneous ideals of $R$ that are all generated in degree $1$ (that is, each $I_i$ has the form $I_i = V_i R$ for some $k$-vector subspace $V_i$ of the degree-$1$ homogeneous component of $R$). Then, the ideal $I_1 \cap I_2 \cap \cdots \cap I_t$ is generated in degree $\leq t$.
Some more questions suggest themselves:
Question 3. (If the answer to Question 1 is negative:) Does the answer to Question 1 become positive if we replace "ideal" by "homogeneous ideal"?
(This would still be enough to reprove Theorem 2.)
Truth be told, I'm less interested in the polynomial case than I am in the exterior algebra case:
Question 4. What if we replace the polynomial ring by an exterior algebra?
(You can assume $k$ has characteristic $0$ for simplicity.)
Finally, if all these questions have negative answers, here is what I am really looking for:
Question 5. Is there an elementary proof of the analogue of Theorem 2 for exterior algebras (which is part of Theorem 9 in Francesca Gandini, Degree bounds for invariant skew polynomials, arXiv:2108.01767v1)?
"Elementary" means no use of nontrivial commutative algebra for me (I'm actually fine with Schur functors, although I have a hunch that they too can be avoided).
I'm putting the invariant theory tag on this question because the ultimate use of Question 5 is in Francesca Gandini's proof of the analogue of the Noether bound for the exterior algebra, which I have asked about in Noether's bound for anticommutative invariant theory (diff. forms instead of polynomials)? and am now trying to understand...

Report by Brookings Institution's Geoff Gertz '07 Shows Rapid Reduction in Global Poverty
May 28, 2011
May 28, 2011, Greencastle, Ind. — "Most people haven't noticed yet, but according to a recent study by the Brookings Institution in Washington, we have just lived through the most dramatic decrease in global poverty in history," notes a story published today in Canada's National Post. "And the transformation has almost nothing to do with debt relief or higher aid flows. According to the Brookings report, 'Poverty in Numbers: The Changing State of Global Poverty from 2005 to 2015,' we are living in a period of rapid global poverty reduction that is driven by high, sustained economic growth across the developing world. Nearly half a billion people escaped living at or below the poverty threshold of U.S. $1.25-a-day between 2005 and 2010, say the study's authors Laurence Chandy and Geoffrey Gertz. 'Never before in history have so many people been lifted out of poverty in such a short period,' they said."
Geoff Gertz, a 2007 graduate of DePauw University, is a research analyst, global economy and development, at Brookings Institution.
In 2007, Gertz is received a Junior Fellowship from the Carnegie Endowment for International Peace. Details are available in this previous story.Back


Strigo's labs allow attendees to access resources using full internet access, as well as access other labs for cross-lab interactions.
Network Access
Strigo's labs have all ports opened by default (both inbound and outbound). This is true for both internet access and cross-lab access.
Each lab has both dedicated public and private IP addresses (as well as resolvable DNS addresses).
Limiting network access
Note: Strigo does not currently allow limiting network access out of the box. We've aware of the need, and will provide a solution for this in the future.
To limit network access to your labs, you can use the firewall software provided with your lab resources' operating systems (most Linux and Windows distributions have them pre-installed).
Communicating between Labs
Strigo's lab resources can access one another via private and public networks. As mentioned above, all ports between all lab resources are open, and so you can configure access between the resources in whichever way suits your needs.
Note: If a static configuration is required to access other lab resources, is it highly recommended not to use public IP's or DNS, as these may change.
Creating virtual networks between lab resources
You may require a more complex network configuration between lab resources (for example, to create a network where IP's are static).
Note: Strigo does not currently allow creating a virtual network between lab resources out of the box.
However, you may use SDN solutions (such as OpenVPN or Wireguard), and configure those using userdata (LINK) or our post-launch scripting layer (LINK) to configure more complex networks.
Retrieving Network Information
Within the classroom
You may need to retrieve information like the private or public IP address of a lab (or its DNS host name). This can be useful for communicating between lab resources or for accessing them outside of Strigo for different purposes.
To retrieve network information for a lab resource, click the cogwheel to right of the lab's name and then click "Machine Info". You can then copy any relevant information about the lab.
Using our REST API
You may use our REST API to retrieve lab network information.
When are lab IP's changed?
If you rely on having static IP's in your lab configuration, consider the following limitations:
 - A lab resource's public IP and public DNS can change when either replacing the lab resource or returning to an on-demand environment.
 - Private IP's and public DNS should remain the same unless replacing the lab resource.
Differences between different operating systems
There's practically no difference in network access between operating systems. Whether you work with Windows, Linux, or a custom distribution, and as long as your software allows it, network access is configured similarly.

Hormones in Metamorphosis of Amphibia
In amphibians, the changes that take place during metamorphosis are brought about by hormonal secretions of the thyroid gland. The first sign of this was obtained in 1912 when Gudematsch reported that frog tadpoles while fed dried and powdered sheep thyroid underwent precocious or early metamorphosis. Identical results however were not observed when tadpoles were fed along with preparation of other glands. These experiments made it feasible to postulate that thyroid hormones bring about metamorphosis.
In 1918 B.M. Allen observed that elimination of thyroid rudiment from early frog tadpoles, prevented them from going through metamorphosis, and caused them to become giant tadpoles instead. Conversely, if they were fed with thyroid or immersed in water containing soluble extracts from thyroid glands they then proceeded immediately to metamorphosis. Identical experiments in urodele amphibians, in particular in axolotl, Ambystoma mexicanum, also indicated the significance of the thyroid gland in urodele metamorphosis.

The Zanclean flood (also known as "Zanclean Deluge") is a flood theorized to have refilled the Mediterranean Sea 5.33 million years ago, at the beginning of the Zanclean age, between the Miocene and Pliocene, which ended the Messinian salinity crisis. The term was coined by Maria Bianca Cita in 1972 during the Deep Sea Drilling Project study which investigated specifically the transition between the Messinian and Zanclean ages in the Mediterranean.
According to this model, when water from the Atlantic Ocean refilled the cut-off inland seas in the Mediterranean basin that had become desiccated (see Messinian salinity crisis), flooding occurred through the basin. A channel opened from the Atlantic Ocean, through the modern-day Gibraltar Strait, and carried ocean water over a distance of over 200 km. The Mediterranean Sea was filled over a period estimated between several months and two years. Sea level rise in the basin may have reached rates at times greater than ten metres per day.
Water rushed down a drop of more than a kilometer with a discharge of up to 108 m3/s, about 1000 times the present day Amazon River, but studies of the underground structures at the Gibraltar Strait show that the flooding channel descended in a rather gradual way toward the bottom of the basin, rather than forming a steep waterfall.

Since the Prophets are the role models for the people, Allah beautified them with the praised attributes. He also protected them and purified them from having disgraceful attributes. It is impossible for the Prophets to be attributed with lying, dishonesty, vileness, foolishness, and dullness. They are also protected from ever committing blasphemy, enormous sins (kaba'ir), and the small, abject, and despicable sins before and after Prophethood. However, they may commit, non-despicable small sins, and if they do commit such sins, they are immediately guided to repent before others imitate them.

British Scientists Invent Hydrogen Based and Cheaper Artificial Gasoline
British scientists are refining the recipe for a hydrogen-based fuel that will run in existing cars and engines which could cost just around $1.50 a gallon and is more energy effiicient than the nowadays petrol. The hydrogen-based fuel instead of carbon-based (as it is heavily used in nowadays petrol) doesn't emit any harmful greenhouse gases […]


text: In this paper, we analyze a game called the lowest unique bid auction (LUBA). It is known that there is no closed form solution for the symmetric mixed strategy equilibria in LUBA. We propose two alternative approaches. We use weak dominance to identify upper bounds for players' bids. Under symmetry, we provide a method to compute a mixed strategy equilibrium by utilizing the recursive structure of the winning chances of the bids under one assumption.

Causes two expressions to be executed sequentially.
The, operator causes the expressions to be executed in left-to-right order. A common use for the, operator is in the increment expression of a for loop. For example:
The for statement allows only a single expression to be executed at the end of every pass through a loop. The, operator allows multiple expressions to be treated as a single expression, so both variables can be incremented.

15th Biennial Workshop of Joint Numerical Sea Modelling Group (JONSMOD)
B. Viikmäe from the Tallinn team presented a paper aiming at creating a technology that would provide a substantial decrease of remote environmental risks (e.g. ship-caused pollution that frequently affects vulnerable areas far from the accident site) by minimizing the consequences of potential accidents. The central idea is smart use of the existence of statistically heterogeneous
semi-persistent current patterns, which considerably affect pollution propagation as well as drift of various items such as vessels without propulsion, rescue boats or lost containers.

2 Answers
 1. you are talking about converting to a buffer of bytes
 2. You are using UDP and performance is a concern
Try to avoid wasting space in your packet for defining structure. I.E. send, at minimum, a byte to denote the type of packet, then just assume each packet received follows the predefined structure for that type of packet
 - Yes, read the whole struct IF you NEED the whole struct
 - No, make the packet structure yourself, This will surely be smaller than serialization using these methods; you should know exactly what data the packet should include
How should I represent arrays of data?
 - As arrays of data. When receiving continue reading the buffer until end of data to avoid sending a Count of the array's elements
What should the interface look like for packing/unpacking data?
 - You could easily setup a bunch of methods to convert basic types to bytes, from there build on these methods to convert custom types as well. The specifics on how to do this could be found almost anywhere I'm sure (I use C# personally)
One last thing, packet size is a concern, especially for a snapshot: size = packetSize x entities x connectedPlayers; So you might have 60 x 10 x 16 = 9,600 bytes per packet Then sending this 20 times a second: = 192,000 bps = 187 KBps. This is obviously a high bandwith upload speed. Thus the need to minimize each of the factors contributing to packet size where possible.

Another article that I discovered while reading various object serialisation and networking questions here a few weeks ago was this one which describes how the Unreal engine does it. A good point of comparison for the Valve source. – Martin Foot Aug 31 '11 at 8:42
Your array method is not going to work in the general case - where is the 'end of data'? Even if your messages are delimited, it would mean you can't have more than 1 array per struct. To fix this, the original poster could either stick to fixed length arrays, or ensure there's only 1 array per struct (at the end of the struct), or send a count value at the start of the array. – Kylotan Aug 31 '11 at 10:48
Just one more tip: Remember to treat endianess, this can be very anoying if you don't know that such thing exist. – user9471 Aug 31 '11 at 13:03
Good point _USER_, agree that in certain cases this extra data can't be avoided; but if I find myself adding multiple arrays to a single packet, I would consider sending multiple packets instead – indeed005 Sep 1 '11 at 0:47

This problem has been solved by Google and Facebook:
 1. Google's Protocol Buffers — Google is a big user of C++:
 2. Apache Thrift (formerly by Facebook):
share|improve this answer
Google's Protocol buffers are too slow for larger scale, real time games. I did find them quite nice for prototyping and smaller player numbers because of the versioning, however. As usual, your profiler will tell the real story. – Patrick Hughes Sep 2 '11 at 17:48
Well, they're good enough for Google, and Google scales pretty well, and they worked well when I used them. That's why I recommended them. – a paid nerd Sep 2 '11 at 20:57
Google doesn't require real time performance. Google does require reliability and up-time, both of which are well served by Protocol Buffers. The complexity of all that fallback versioning and boilerplate code generation adds overhead and when you're sending and receiving 1000 updates at 50-100msec intervals it adds up. Profile a Protocol buffer several versions old against a coded serializer specific to the data at hand. _USER_ has the gist of it. – Patrick Hughes Sep 2 '11 at 21:22
+1, because although these formats are a bit too large and slow for most real-time or high-bandwidth games (due to containing extra information that allows you to reconstruct arbitrarily complex packets), that's not to say they aren't useful in some games, eg. turn-based ones. If optimising every resource isn't necessary then these formats can save you a lot of time, and they're certainly more efficient than JSON. – Kylotan Sep 4 '11 at 12:27

The COVID-19 pandemic has negatively affected the mental health of older adults. They have been encouraged to stay at home, and restrictions have limited social interactions and increased social isolation. Social isolation is associated with increased emotional distress and depressive symptoms in older adults. Despite the increase in isolation during the pandemic, there have been limited studies that examine differences in mental well-being between household compositions. The purpose of this study is to investigate whether religious belief, networks, and technology usage influence the mental well-being of older adults in coupleand single-households during COVID-19. It is important to understand how various factors impact mental health for older adults living in different household types during the pandemic as this may guide future interventions.
This study used Health and Retirement Survey COVID Project data. The sample was comprised of respondents aged 60 or older (N=1,249). The independent variables consisted of age, gender, education, race, ethnicity (Hispanic), perceived health, household income, digital technology usage, religious belief, and network with a spouse, children, other family members, and friends. This study adopted scales of mental health, digital technology usage, religious belief, and networks from HRS. Simple regression analyses were conducted with coupleand single-households to examine what factors affected older adults' mental health during COVID-19.
The study found that perceived health, religious belief, network with other family members, and digital technology usage have different impacts on the mental health of older adults. In couple households (n=795), health [b=1.7], digital technology usage [b=0.3], and network with spouse [b=0.2], children [b=0.2], and friends [b=0.2] had significant positive effects on mental health [p<.05]. Regarding the single older adults (n=448), their mental health had positive relationships with perceived physical health [b=1.9], religious belief [b=0.1], and network with children [b=0.2], other family members [b=0.2], and friends [b=0.3, p<.05].
Conclusion and Implications
This study contributes to a more complete understanding of what factors positively impact mental health outcomes in older adults during the pandemic and how perceived health, networks, religious belief, and digital technology usage impact individuals in different household types. The study results indicate that perceived good health status had a positive impact on older adults' mental health in both household types. The findings suggest that technology use and closer relationships with a spouse, children, and friends are associated with better mental health outcomes in couple households. On the other hand, closer relationships with children, friends, and other family members and religious belief were important for the mental well-being in single households. Using technology had no significant relationship to mental health in single households. However, since the pandemic began, research has revealed that technology use has a significantly positive capacity to promote mental health in couple households. Further research is needed to understand factors related to technology use in single older adults. Increasing technology use may help prevent isolation and improve mental well-being in single households.

The Healthy Diver: Drink Up
drinking water
Hydration can be a major problem to your health even when you are completely surrounded by water. In fact, all the delights of a dive vacation — a hot sun, rum punches, long hours spent on the water — can leave you as dry as desert sand. How can you avoid becoming dehydrated, which could put an early end to an amazing diving adventure, and learn to recognise the symptoms?
A few common symptoms like headache, fatigue, or feeling dizzy can be overlooked or attributed to other causes. But when these symptoms accompany others, such as a dry mouth or being excessively thirsty, dehydration is likely the cause. Some of the most common effects from mild dehydration is cramping because not enough water is taken to your muscles and overall exhaustion and weakness. While that may not sound very severe, the more dehydrated you are, the more difficult it is for you to remain focused and self aware of your surroundings. You are also at a higher risk of having decompression sickness. On a dive vacation, some of the factors leading to dehydration are:
1) Sweating. Perspiring is the body's internal a/c, a cooling mechanism that releases a significant amount of water. It's common to sweat in hot, exotic locations — and that's without the extra stresses and workload a diver has. Divers sweat while loading and offloading gear from a boat, finning against a current, and wearing a wetsuit for a prolonged period of time.
2) Sunburn. Soaking up the sun's rays can be dangerous. Relaxing on the beach can lead to sunburn and as your body struggles to repair the damage, water seeps into the damaged skin and the body loses fluids.
3) Immersion diuresis. This is the correct term for peeing in your wetsuit. Immersion in water, especially in water that is colder than the air, causes narrowing of the blood vessels in your arms and legs, sending more blood back to your body.
9 Tips for Travelling Divers
health check
Health News:
Nobody plans to get ill on a dive trip, but the fact is it can happen. It will be less likely and less traumatic if you are careful and prepared.
The first step is, of course, don't get sick, so here are some effective preventative measures you can take:
1. Stay as far away as possible from others who appear sick (e.g., folks who are coughing, sneezing).
2. Wash your hands frequently while travelling and keep them away from your nose, mouth and eyes.
3. In the developing world, be prudent about drinking water from the tap. Stick to bottled drinks, especially water, and make that ice you use also comes from distilled or bottled water.
4. Avoid unshelled fruits and vegetables. Stick to fruits with hard shells and avoid berries. If you chance it with leafy greens, they should be very well washed with clean water.
5. If you are in an area with insects, wear long sleeves and pants, avoiding dark or bright colors, especially at dawn and dusk. Try to stay indoors at dawn and dusk when many flying insects are most active.
6. Wear a proven insect repellent or a picaridin-based repellant containing at least a 15% concentration.
7. Avoid scented toiletries and perfumes, which attract insects.
8. Get necessary vaccines before departure. You can check with your primary care physician but it's very unlikely he will be travel-medicine savvy. Alternatively, locate a travel medicine specialist through ASTMH/ACCTMTH directory or my favorite, little-known gem, Passport Health to find out what's currently being recommended for a specific destination.
9. Verify that your health insurance provider covers medical expenses abroad as many do not. Familiarize yourself with the details of your medical coverage, and especially with the process for documenting a claim (even DAN can be a problem if you don't carefully follow the rules). In addition, it's prudent to secure an IAMAT (International Association for Medical Assistance to Travelers) membership. It's free and the organization maintains a network of approved health professionals throughout the world who offer services to travellers at a fixed rate.
If your carrier doesn't cover you overseas, consider purchasing traveller's insurance.
Thirteen Things You Didn't Know About Scuba Diving Gear - But Should

Thirteen Things You Didn't Know About Scuba Diving Gear - But Should
Divers have an intimate connection to their equipment. But the history, evolution and hidden inner workings of many integral pieces of our collective kit might be a mystery to many of us. Knowing more about your scuba diving gear is essential.Check out these 13 curious details, historical head-scratchers and surprising facts, including why dive watches glow and what the heck is the "Bends-O-Matic?". In Turtle Bay Dive Resort, we not only serve you, but we give you more information about the diving world.
1. One of the earliest "dive computers", the SOS Decompression Meter, was completely mechanical and simulated the process of gas absorption in the body. Its sketchy performance earned it the nickname "Bends-O-Matic."
2. The first decompression tables, and the basis for modern dive computer algorithms, were published in 1908 by John Haldane. They were based on simulated dives using a hyperbaric chamber. The test divers were English goats.
3. Depth ratings for extreme deep dive watches have exceeded the known depth of the oceans. The Sinn UX is rated to 12,000 meters, more than 1000 meters deeper than the Marianas Trench.
4. Tritium, a radioactive material safely used in tiny quantities to make illuminated markings in many dive watches, is also used as a "booster" in multi-stage hydrogen bombs.
5. The rhythmic, mechanical breathing of Star Wars' Darth Vader is iconic. It's the amplified sound of a scuba regulator.
6. Jacques-Yves Cousteau and Emile Gagnan invented the Self-Contained Underwater Breathing Apparatus in 1943. It was based on a diaphragm regulator design first developed more than a hundred years before.
7. Last year, Allen Sherrod, a dive instructor from Florida, spent 48 hours and 13 minutes breathing from a regulator while submerged off Lauderdale-by-the-Sea, Florida. It was a world record time for a saltwater dive.
8. Many warm-water divers use their octopus as a defense against stinging jellyfish. A brief purge beneath an oncoming assailant will gently lift it out of the diver's way.
9. An ancient bas-relief dating back to 900 B.C. shows Assyrian divers using animal skins filled with air, which they carried with them to increase the length of their dives.
10. Before the standard power inflator came along, horse collar BCs incorporated small CO2 canisters to provide emergency inflation when needed, just like many personal floatation devices do today.
11.The popular backplate-and-wing BC design came as a cave diving innovation and improvement over "belly bags," which uncomfortably sandwiched divers between an air bladder and a pair of heavy steel tanks.
12. No welding is used in making a typical aluminum scuba tank. Instead, a 32-lb. aluminum slug, 7-inches across, is pressed into shape by 2,500 lbs. of pressure in just 20 seconds.
13. Everyone knows LED lights are more efficient than incandescent models. But how efficient is it? Tests have shown that burn times may average 30 times longer using identical battery power.
Are Split Fins Right For You, Or Maybe another type of fins? - Turtle Bay Dive Resort
describe the image
 Are Split Fins Right for You?
When cruising the depths, do you find yourself nagged by ankle strain when kicking through the water? Does the most minimal fin stroke get your knees and leg muscles barking like a pack of dogs? Do you like the ability to kick into a current or chase a bat ray without getting overly fatigued or cramping up? Are you a big fan of the flutter kick? If so, you might be a candidate for split fins.
Split fins slice through the water with far less resistance than traditional paddle fins. That's because rather than pushing against the water with brute force, the flexible blades of a split fin, when engaged in an up-tempo flutter kick, actually generate lift along with a jet propulsion effect, similar to a boat's propeller. The faster the propeller turns, the more propulsion is generated. In other words, with split fins power comes from the speed of a diver's kick rather than the force of the kick. The result: excellent acceleration and the ability to sustain speeds and cover a lot of ground with minimal effort or leg strain.
Of course, like anything else, there are good split fins and not-so-good split fins, so performance results will vary. Also, due to the principles of the design, the best kick for a split fin is a narrow (inside the body's slipstream), rapid flutter kick. If that type of kick is not your cup of tea — if you prefer sculling or the

If you have blepharospasm, at first, you may notice increased and uncontrolled blinking when you are tired, anxious, physically or emotionally stressed, or when you are exposed to bright light or sunlight. Over time, the uncontrollable blinking becomes worse. It may feel like you have no control over your eyelids and that it takes a lot of effort to open them. Blepharospasm can be severe enough that it may force the eyelids closed for several hours at a time.

text: By 1953, the United Nations, Korean Reconstruction Agency (UNKRA) had allocated nearly $8,500,000 to rebuild South Korea's educational system. This year, if enough funds are forthcoming, the Agency plans to spend another $2,875,000 for the same purpose. Some 300,000 textbooks have been bought for the drive against illiteracy. More than 3,000 tons of paper have been imported to print another 38,000,000 textbooks. The Government of Korea and the United Nations Educational, Scientific and Cultural Organization (UNESCO) worked with UNKRA on a textbook printing plant near Seoul. This plant, which opened on 16 September, is expected to have produced about 15,000,000 textbooks by the end of the year. This picture shows the distribution of new books to a class of young Korean schoolchildren.

The cortical collecting duct
is where all of the distal tubules
of the nephrons
in the kidneys
feed. It is fed by many nephrons, and is the last chance
for the kidney to reabsorb
any of the filtrate
before it enters the renal pelvis
and is later excreted
Angiotensin II causes sodium and chloride reabsorption in the collecting duct, as well as in the distal tubule. Its permeability to water is controlled by antidiuretic hormone (or vasopressin, as it is also known). Water reabsorption is aided by the duct's positioning within the renal medulla, where the interstitial side of the membrane has a very high osmolality (hyperosmolality). This draws water back in when the membrane is permeable to it, via osmotic pressure. This increased permeability is due to the insertion of more aquaporin proteins in the membrane upon binding of vasopressin.
The collecting duct also reabsorbs urea, and excretes around 30 percent of the absorbed potassium. The potassium absorption in the collecting duct is due to potassium-specific ion channels, and is passive. Regulation in the duct is active, and is done via sodium-potassium ATPase.
These are my interpretation of my lecture notes, but I may have used some references from Hole's Anatomy and Physiology (Shier, Butler, Lewis) and Human Physiology (Vander, Sherman, Luciano)

The trivial solution of xy=xy is for x=y=2, and xy=xy=4.
4 is also the only x for which there exists a k such that hy(k, n, k) for all n (where hy(a, b, c) is the generalised hyper function).
For information about superstitions related to this number, see tetraphobia.
The cube of the golden ratio phi, and the value of these three expressions all involving Φ and its square:
Φ2 × Φ = (Φ2}2 - (Φ)2 = (Φ2}3 / (Φ)3
Thus, Φ2 and Φ are the answer to an old algebra problem (from 78):
What two numbers are those whose product, difference of their squares, and the ratio or quotient of their cubes, are all equal to each other?
It is also equal to 1+2Φ. See also 2.618033...
The (first) Feigenbaum constant, commonly designated by the Greek letter delta.
It appears as the limit of the ratio of successive intervals between period-doubling domains in the iteration of a quadratic mapping, when varying the parameter continuously from the stable (single-attractor) domain towards the chaotic domain.
x <- l x (1-x)
where l is the parameter.
In the Mandelbrot set, it shows up as the ratio between each "circle" and the next smaller one in the series of "circles" on the real axis connected to the large cardioid. (Only the first of these, the one centred at -0.75, is actually a perfect circle.) For more information, click here.
The value is approximated to 7 digits by the formula π+arctan(eπ) (which is 4._PHONE_...)
The second Feigenbaum constant is 2._PHONE_....
Because 6 is in A1109 (see 204 for details about that) and because its square 36 is triangular, this makes 6 a triangular number whose square is also triangular, the only such case apart from 0 and 1.
There has been a grass-roots movement (beginning roughly at the time of Palais' 2001 opinion article in The Mathematical Intelligencer ) to replace the use of π with this constant. Palais called it "tau", but used a new "three-legged pi" symbol instead of the Greek letter τ, and described a "blight of factors of 2" throughout mathematics and physics that might be eliminated by replacing π with.
Indeed, using this constant, some formulas become a little more elegant: we have cos(x+)=cos(x) in place of the normal cos(x+2π)=cos(x); Euler's identity becomes ei=1 rather than eπ=-1 or eπ+1=0; and so on. However, "tau" is a fringe culture phenomenon, and not accepted for use in e.g. high school or university mathematics education.
According to Randall Munroe's What-If Numbers stream on Twitter, 6.5 is the "mass, in grams, of a kilometer-long strand of human hair". You'll find many similar numbers, most of them have units and/or are variable in value (example: "ounces of gold it would take to buy one ounce of 64GB MicroSD cards").
The smallest positive integer whose reciprocal has a pattern of more than one repeating digit: 1/7 = 0.142857142857... It is also the smallest number for which the digit sequence of 1/n is of length n-1 (the longest such a sequence can be). The next such numbers are 17, 19, 23, 29, 47, 59, 61, 97, 109, 113,... (Sloane's integer sequence A6883). See 17 for more on this; see also my separate article, Fractions with Special Digit Sequences.
Tests for divisibility by 7 are difficult. About the best one I've found is as follows (demonstrated by testing _PHONE_):
- Remove the last digit and subtract twice this digit from the remaining number: 415672 - 2×6 = 415660 (You are subtracting 21×d and dividing by 10, where d is that last digit.)
- Repeat this process: 41566 - 0×2 = 41566, 4156 - 6×2 = 4144, 414 - 4×2 = 406, 40 - 6×2 = 28
- The result is a multiple of 7 if and only if the original number is.
There is another divisibility test that works as follows:
- Alternately add and subtract groups of 3 digits starting from the right: 726-156+004=574. (If the result is negative, drop the sign) (This is done because 7 is a factor of 1001.)
- If greater than 999, repeat the previous step.
- Add the 1's digit, 3 times the 10's digit and twice the 100's digit: 4+3×7+2×5=35. (The reason for the multipliers: 1 = 1 mod 7, 10 = 3 mod 7, and 100 = 2 mod 7)
- If desired, repeat previous step until result is small enough to tell at a glance if it's a multiple of 7: 5+3×3=14.
- The result is a multiple of 7 if and only if the original number is.
7 is considered "lucky" by many people and given much spiritual significance. The early religious and cultural use of the 7-day week almost certainly arose from the fact that the moon goes through its 4 phases in a bit over 28 days, which divides nicely into 7 days per phase. Another, different connection between moon phases and 7 is that there are 7 easily distinguishable, visible phases of the moon: waxing crescent, first-quarter, waxing gibbous, full, waning gibbous, third-quarter, waning crescent. The new moon doesn't count because you can never see it (the sun is too bright). And there is also the well-known count of the 7 moving objects in the sky: sun, moon, Mercury, Venus, Mars, Jupiter, Saturn.
The square root of 62 has a remarkable digit pattern:
√62 = 7.874 007874 011811 019685 034448...
The "7874" repeats 6 digits later, then we get "11811" (which is 7874×3/2) and then "19685" (which is 7874×5/2).
A similar pattern with an amazing similarity is seen in the square root of 2:
√2 = 1.4 14 21 35 62...
Again we have "14" repeated twice, then 14×3/2 = 21, then 14×5/2 = 35.
These patterns of digits, and the recurrence of the ratios 2:2:3:5, is not a coincidence. They result from the fact that 62 times 127 squared equals 999998, which is a power of 10 minus 2; and similarly, 2 times 7 squared is 98. Note also that 62×127 = 7874, which are the first 4 digits of √62, and 2×7 = 14, the first 2 digits of √2.
For a full understanding, we start with
1/999998 = 0.000001000002000004000008000016000032000064...
a digit pattern featuring powers of 2 which is described in the 998 entry. Now it happens that 0.001000001 squared is 0.000001000002000001 (see 10201), and 0.001000001000001 squared is 0.000001000002000003...
Since 1/999998 = 0.000001000002000004... is a little bigger than this, it makes sense that its square root should be a little bigger than 0.000001000001000001:
√1/999998 = 0.001000001000001500002500004375007875...
The sequence (1, 2, 4, 8, 16,...) has become (1, 1, 1.5, 2.5, 4.375,...) Those two 1's make the repeated digits possible.
Now instead of the square root of 1/999998, we want the square root of an integer. Since the factors of 999998 are 2×31×1272, we can multiply √1/999998 by 2×31×127, which is 7874. The 7874 goes inside the radical and becomes 78742, then most everything cancels out:
7874 √1/999998 = √7874×7874/999998 = √62×999998/999998 = √62
√62 = 7874 √1/999998 = 7874 × 0.001000001000001500002500004375007875... = 7.874007874011811019685034448812007863...
So we started with 999998, which is 2 fewer than a power of

With spring blooming all around us here in the United States, it's natural that our thoughts go to, well, last spring, specifically the "Arab Spring" that saw the rise of people's revolutions and the fall of tyrannical governments. Unfortunately, the average American recalls that tumult as an excited blur, mainly because of the general ignorance not only of the history of that region, but also of our country's significant role in that history. For anyone wanting to sharpen that blur into a clearer view, the graphic novel Best of Enemies: A History of US and Middle East Relations, Part 1: _PHONE_, written by Jean-Pierre Filiu and illustrated by David B., is a good start. Be prepared to discover that the clearer picture isn't a pretty one for Americans, but one that we need to see to have any hope of ever breaking free of the relentless cycle of history.
Graphic novels and comics in general still suffer from the misperception in some circles of being child's play. Best of Enemies is nothing but a serious, adult matter. French historian Jean-Pierre Filiu is an internationally recognized expert on the Middle East. Few writers could bring a more comprehensive, incisive mind to untangle the baroque turns of American—Arab relations since the late 18th century. Fellow Frenchman, Pierre-François "David" Beauchard, better known by his comic artist pen name David B., takes Filiu's words and gives them form with his characteristic overflowing and highly symbolic style. American readers remember David B. best for his autobiographical graphic novel Epileptic, in which the artist recounts his childhood centered around his brother's epilepsy, which became the greatest fear and symbol of his youth. Similarly, David B. takes aspects of the history of the U.S. in the Middle East and turns fears into symbols and, in turn, into understanding.
Best of Enemies begins at the beginning of storytelling, with a brief recitation of the Epic of Gilgamesh. Just when you think you've oriented yourself in that ancient epic, the characters begin to sound like modern warmongers, as the authors insert the words of contemporary war architects into the mouths of Gilgamesh and Enkidu. Filiu and B. follow up that surreal set-up with a troubling parallel between the pile of bodies in the ancient Stele of the Vultures and the "dogpile" of the infamous Abu Ghraib photos. These opening episodes set the tone of telling parallels and tragic repetitions that mark the whole history.
Filiu and B. excel in breaking down the complexities of the history into intelligible parts. The first part uses the natural appeal of piracy to draw the reader in. What most Americans only know vaguely as "the shores of Tripoli" from the "Marines' Hymn" becomes the full story of the American battle in the 1780s with the Barbary States of Tripoli and Algiers. "And so America was no sooner born than it found itself at war with countries thousands of miles away," Filiu writes, drawing immediately to mind more recent parallels such as Vietnam, Afghanistan, and Iraq. Not much later, President Thomas Jefferson approves an American-engineered overthrow of a Middle Eastern government, starting the sad precedent repeated far too often. The war on water quickly transitions to the war for oil that we know so well today. The final chapter focuses on Jefferson's legacy of the coup d'etat as it played out in 20th century Iran when America forced the Shah on the Iranian people.
David B.'s art matches the clarity and memorable quality of Filiu's writing. For example, the familiar turban of the stereotypical American idea of the Middle East becomes a powerful motif in B.'s visual scheme. The swirling lines of the turban symbolize the swirling lines of conflict between powers, but B. finds great versatility in that single symbol. In one image, the lines of the rounded turban become the waves upon which naval battles are fought under different flags (image shown above). An incensed Jefferson stomps away from failed treaty negotiations across a similar turban globe as John Adams beseeches him to reconsider. Even later, a turban becomes a merry-go-round of political intrigue punctuated by murderous succession to the throne.
I came away from Best of Enemies with a feeling of loss paired to the feeling of understanding gained. I knew America's involvement in the Middle East was a long, dark one, but seeing personal heroes such as Jefferson and Franklin Delano Roosevelt with blood on their hands opened my eyes to the immensity and pervasiveness of the problem. No single volume can hope to explain the tortured relationship of the U.S. and the Middle East, but Best of Enemies sheds light on this dark "friendship" that might enlighten and, hopefully, inspire change.

- "Splice"-like hybrids have been banned in Ohio, Arizona and elsewhere.
- Scientists say the research could cure cancer, HIV, diabetes, other deadly diseases.
- Opponents worry about the moral issues of combining animal and human cells.
Dren, the half-human, half-animal hybrid set to terrorize Adrien Brody and Sarah Polley in the new movie "Splice," is pure science fiction, but politicians across the country aren't taking any chances.
In the last month Ohio and Arizona have both passed laws forbidding research of animal human hybrids.
Proponents of the laws fear Dren-like creations and object morally to the combining human and animal cells. But scientists say the research could lead to cure for AIDS, immunize people against cancer, or grow replacement organs.
The potential for medical cures or advances is huge, said Esmail Zanjani, a scientist at the University of Nevada Reno who has created sheep that produce livers that are up to 20 percent human.
"But just because we can do something doesn't mean we should," said Zanjani. "We need to have a full discussion with the public," about this kind of research.
In a recent interview, "Splice" director Vincenzo Natali said that his inspiration for "Splice" was the earmouse, a 1995 experiment where scientists grew a large, human-shaped ear from cow cells grown on the back of a hairless mouse.
Despite the fact that no human cells were used in the ear mouse (the scientists placed cow cells on a polymer shaped like the human ear), the research sparked controversy and raised hopes that replacement organs would soon be available.
Since then research into animal human hybrids, or chimeras (after the lion, goat, and snake creature from Greek mythology) has exploded. Over the last 15 years scientists have created sheep with human livers and pancreas cells, mice with human immune systems, and many other combinations of human and animal cells.
None of the modern chimeras look like something out of Dr. Moreau's menagerie. They look like normal animals. The difference is on the inside.
The blood flowing through their veins could be human. The liver or kidneys could contain discrete human liver or kidney cells. These are not transgenic animals, said Zanjani. They are discrete cells, either animal or human. The DNA is not mixed.
If a human had, say, hepatitis, and their liver was dying, scientists could extract liver cells from that person, insert them into a developing sheep, and then harvest a human liver, made from a person's own cells (to reduce the chance of organ rejection), and replace the old liver.
Infected cells can't fight off an infection, whether it is HIV or some other disease. But if uninfected human stem cells were placed in an animal's body, scientists could train those cells to recognize and fight off the infection.
Once they are ready, the cells would be harvested from the animal and introduced back into the original human's body. There the retrained immune cells would fight off the infection.
The same technique could work for cancer, said Jeffery Platt, a scientist at the University of Michigan exploring this very scenario.
Millions of lives could be saved using human-animal hybrids, say scientists, but some people have strong moral objections to mixing human and animal cells. Earlier this week the Ohio Senate passed Senate Bill 243, which prohibits "the creation, transportation, or receipt of a human-animal hybrid, the transfer of a nonhuman embryo into a human womb, and the transfer of a human embryo into a nonhuman womb."
Anyone who violates the new law could spend five years in prison and face up to a quarter million dollars in fines. Other states, including Louisiana, Oklahoma, and Arizona have also banned research into chimeras.
National governments have also stepped in. The United Kingdom approved chimera research in 2008, when it granted a Newcastle University stem cell scientist Lyle Armstrong a permit to use cow eggs filled with human DNA to develop therapies for Parkinson's disease and stroke victims. (All cow DNA would be removed before the human DNA would be inserted.)
Canada bans all chimera research, but the Human-Animal Hybrid Prohibition Act of 2009 failed to pass the U.S. Congress.
Fears about new technology are nothing new, said Platt; the advent of railroads sparked controversy about how fast the human body was meant to travel. Nor are they unnatural; people fear what they don't know. But the potential of chimera research to save millions of lives should also be added to the equation.
"Where it becomes a problem is if government responses with undue constraints that are not justified," said Platt.

CAON®-KORWI® Silicone Covers have been developed as a protective measure against bird electrocution on overhead electric distribution and transport lines with a maximum voltage Um between 15kV and up to 66kV (depending on the model), offering a Phase-Earth dielectric rigidity value of Um/√3.
These devices are designed to be installed on existing lines and on those in which our Bird Protection Insulators models C3670EBAV_AR, _PHONE_ and _PHONE_ cannot be installed.
The aim of these devices is to protect birds from electrocution caused by the bird contacting a conductor and support at the same time, and by the bird contacting two conductors at the same time. These devices are equally effective at protecting overhead lines against other causes of short circuits, such as those caused by tree branches, vandalism, etcetera, avoiding the risk of a fire and electrical service interruptions.
MANUFACTURED WITH >> SPECIFIC ADVANCED FORMULATION SILICONE (Pg. 75) WITH A HYDROPHOBICITY LEVEL of Hc2. Due to their composition and nature they repel the build-up of moisture and are permeable to Oxygen. These devices have a minimum silicone thickness of 3 to 3.5mm (depending on the model), ensuring excellent performance under exposure to UV radiation, with no colour degradation or crystallisation, and they are effective even in areas with extremely high saline pollution. Thanks to their advanced technology, our covers show Lower Leakage Currents, thanks to the hydrophobic properties they transmit to the contaminant layer.
- GUARANTEE: Our Silicone is Ozone Resistant (UNE EN 60811-403) and thanks to its advanced formulation it can improve its dielectric strength (Pg. 75) after passing the 1000h Weathering Test – UNE EN 60243-1. In addition, the 5 000h Weathering Tests, -IEC 6119 Annex C-, performed at the STRI (Sweden) Laboratory – which include the harmful effects of Saline Fog – allow us to estimate the service life of our covers at a minimum of 20 years.
- ENVIRONMENT FRIENDLY AND SUSTAINABLE: The material used to manufacture the covers is a safe inert material, containing no microbial agents and giving off no contaminants to the surrounding environment. It can be easily recycled at the nearest waste collection point. The packaging is made with recycled carton sealed with organic paper adhesive tape.

Spanish researchers have developed on a nanometric scale a new drug that combines photothermia and chemotherapy to help fight cancer.
Until now, researchers have applied this new drug on human glioma cell cultures in the laboratory. The results are particularly interesting for the treatment of skin cancer (melanoma) and solid tumors of the nervous system such as gliomas. The work was coordinated by Professor Eduardo Fernández Jover (Miguel Hernández University of Elche) and Pablo Botella, researcher at the Institute of Chemical Technology of Valencia.
The new drug comprises hybrid particles containing clusters of gold nanoparticles protected by a covering of porous silica which incorporates molecules of an antitumor drug (camptothecin).
The gold nanoclusters have photothermal activity, absorbing the light generated by a biomedical laser. Pablo Botella explains that while organic tissues are virtually transparent to this radiation, its absorption by the gold nanoclusters causes a large local temperature increase. "When this occurs within a cancer cell, the high internal stress leads to its destruction".
The accumulation of these nanoparticles in cancer cells is greatly favoured by the increase of vascular permeability that occurs at a tumor level. Furthermore the release of chemotherapeutic agents transported inside the porous cover of the particles, eliminates those malignant cells that have not been reached by the laser. "This ensures much greater effectiveness than traditional therapy, and the absence of side effects from the antitumor drug in other tissues," says Professor Eduardo Fernández.
"The study has completed its initial phase conducted on cell cultures and, currently, there are plans to develop the next preclinical stage on animal models of skin cancer and gliomas. However, it is still early days to start on humans," the researchers conclude.

Aerospace and Defense
Aerospace and Defense assets travel over land, through the air, in the sea, and up into space. Normal transport and operating conditions can be pretty extreme compared to other industries. Mission-critical assets must undergo rigorous testing to verify they are rugged enough to maintain functionality and integrity, both during transport, as well as during operation.
Lansmont is helping the development of new vehicle designs that improve survivability of blast events. Specialized impact testing systems can replicate horizontal and vertical blast effects, making it easier to research seats and crew compartments that mitigate as much of this shock energy as possible. SAVER Field Instruments are routinely used to measure and monitor these shipments to ensure safe and secure transport.
