The 10-day tour of Europe was not your typical itinerary — Garching, Karlsruhe, Villigen, Hamburg and Oxford. In January. But David Brown and Craig Tull of the Computational Research Division and Alex Hexemer of the Advanced Light Source weren’t touring to see the sights — they more interested in seeing the lights — powerful scientific instruments known as light sources that use intense X-rays to study materials

People who appreciate the beauty of mathematics activate the same part of their brain when they look at aesthetically pleasing formula as others do when appreciating art or music, suggesting that there is a neurobiological basis to beauty. There are many different sources of beauty — a beautiful face and a great symphony are examples of beauty derived from sensory experiences. But there are other, highly intellectual sources of beauty.
A Lawrence Livermore National Laboratory physicist and his colleagues have found a new application for the tools and mathematics typically used in physics to help solve problems in biology. Specifically, the team used statistical mechanics and mathematical modeling to shed light on something known as epigenetic memory — how an organism can create a biological memory of some variable condition, such as quality of nutrition or temperature.
Alan Turing: His Work and Impact, was selected for the top honor, R.R. Hawkins Award, at the 38th annual PROSE Awards. Celebrating the centenary of his birth, the bookwas praised as a fitting tribute to the life of the legendary mathematical and scientific genius, considered to be the father of theoretical computer science and artificial intelligence.
NAG Library for Java Release 2 enables the calling of precisely 1,784 mathematical and statistical routines to aid complex computation, and enhanced error reporting enables increased precision from computation results. It provides abstract classes for callback functions.
Computational scientists now have the opportunity to apply for the upcoming Argonne Training Program on Extreme-Scale Computing (ATPESC), to take place from August 3-15, 2014. The program provides intensive hands-on training on the key skills, approaches and tools to design, implement, and execute computational science and engineering applications on current supercomputers and the HPC systems of the future.
Each audio file has its own history. Editing processes such as cutting and compressing leave their own marks, and this is what researchers use to detect manipulated recordings or plagiarized passages of music with the help of special software.
An enthusiastic group of non-experts, working through an online interface and receiving feedback from lab experiments, has produced designs for RNA molecules that are consistently more successful than those generated by the best computerized design algorithms, researchers at Carnegie Mellon University and Stanford University report.
Ab initio: "From the beginning." It is a term that's used in science to describe calculations that rely on established mathematical laws of nature, or "first principles," without additional assumptions or special models. But when it comes to the phenomena that Milos Milosavljevic is interested in calculating, we're talking really ab initio, as in: from the beginning of time onward.
Computer scientists at Trinity College Dublin and IBM Dublin have made a significant advance that will allow companies to reduce associated greenhouse gas emissions, drive down costs, and minimize network delays depending on their wishes.
Are you a B.Sc. or M.Sc. student in computer science, mathematics, engineering or physics, interested in working on advanced IT projects at CERN for two full months during the summer? CERN openlab has R&D activities on multithreaded programming, data acquisition systems, large scale databases, data analytics, and cloud computing that are open to students who will have completed at least three years of full-time studies.
Raytheon Company will recognize middle and high school math teachers across the country for their commitment to science, technology, engineering and math (STEM) education through grants to support their work in the classroom. The company’s MathMovesU program invites all members of the community to recognize inspirational math teachers and coaches for their dedication to improving math education with a MathMovesU Math Hero Award.
MathWorks announced that The Nobel Foundation has adopted MATLAB to support the asset-liability management strategies of its $500 million (3.3 billion kronor) portfolio and meet its long-term goal of providing monetary awards to future Laureates.
It is one the oldest mathematical problems in the world. Several centuries ago, the twin primes conjecture was formulated. As its name indicates, this hypothesis deals with prime numbers, those divisible only by themselves and by one. Under this assumption, there exists an infinite number of pairs of prime numbers whose difference is two, called twin primes, but nobody has been able to confirm this so far.
Metamaterials are artificial materials engineered to have properties that are not normally found in nature. Typical examples include cloaking materials that can render a person or an aircraft completely invisible to detection. In addition, metamaterials are being explored in a number of cutting-edge technologies including perfect lenses, antennas and terahertz devices.
Finding the most efficient way to transport items across a network like the U.S. highway system or the Internet is a problem that has taxed mathematicians and computer scientists for decades. Researchers describe a new theoretical algorithm that can dramatically reduce the number of operations needed to solve the max-flow problem, making it possible to tackle even huge networks like the Internet or the human genome.
The new HITS research group “Data Mining and Uncertainty Quantification” analyzes large amounts of data and calculates uncertainties in technical systems. With Prof. Vincent Heuveline as their group leader, the group of mathematicians and computer scientists especially focuses on increasing the security of technology in operating rooms.
During particularly intense solar storms the magnetosphere can “crack,” allowing charged particles to seep in and wreak havoc on the Earth’s technological infrastructure — an event called space weather. Scientists currently do not have the ability to accurately predict the severity of a space weather event or where it will have the most impact. But researchers are hoping to change that.
Would you believe that a broad range of human struggles can be understood by using a mathematical formula? From child-parent struggles to cyber-attacks and civil unrest, they can all be explained with a simple mathematical expression called a "power-law." In a sort of unified theory of human conflict, scientists have found a way to mathematically describe the severity and timing of human...
Among the most common tools in electrical engineering and computer science are rectangular grids of numbers known as matrices. The numbers in a matrix can represent data, and they can also represent mathematical equations.
Massive X-ray superbursts near the surface of neutron stars are providing a unique window into the operation of fundamental forces of nature under extreme conditions. The importance of discovering an unknown energy source of titanic magnitude in the outermost layers of accreting neutron star surfaces is heightened by the unresolved issue of neutrino masses, the recent discovery of the Higgs boson ...
The popular math contest Who Wants to Be a Mathematician underwent a makeover this year — the contest that was administered on pen-and-paper moved to a digital format. The number of students in the contest doubled in 2013, with over 2000 students from over 150 schools participating. Maplesoft’s testing and assessment tool, Maple T.A. was used to administer the tests online, saving significant time and money for the organizers.
Researchers at Los Alamos National Laboratory are investigating the complex relationships between the spread of the HIV virus in a population (epidemiology) and the actual, rapid evolution of the virus (phylogenetics) within each patient’s body.
A new algorithm designed at the University of Toronto has the power to profoundly change the way we find photos among the billions on social media sites such as Facebook and Flickr. This month, the United States Patent and Trademark Office will issue a patent on this technology. The search tool uses tag locations to quantify relationships between individuals, even those not tagged in any given photo.
A force that intricately links the rotation of the Earth with the direction of weather patterns in the atmosphere has been shown to play a crucial role in the creation of the hypnotic patterns created by the skirts of the Whirling Dervishes.
The science-fiction writer Isaac Asimov died more than two decades ago, but that did not stop him from writing about a trip to the World’s Fair of 2014. Fifty years ago, Asimov walked into the GE exhibition at the New York World’s Fair of 1964 and declared that “the direction in which man is traveling is viewed with buoyant hope, nowhere more so than at the General Electric pavilion.”
