With over 700 new functions — the single biggest jump in new functionality in the software's history — Mathematica 10 is the first version of Mathematica based on the complete Wolfram Language. Integration with the Wolfram Cloud and access to the expanded Wolfram Knowledgebase open up new possibilities for intelligent computation and deployment.
Discovering a brain tumor is a very serious issue, but it is not the end of the story. There are many different types of brain tumor with different survival rates and different methods for treatment. However, today, many brain tumors are difficult to clearly diagnose, leading to poor prognoses for patients.
Fully automated “deep learning” by computers greatly improves the odds of discovering particles such as the Higgs boson, beating even veteran physicists’ abilities.
A new type of steel-reinforced concrete protects buildings better from bomb attacks. Researchers have developed a formula to quickly calculate the concrete’s required thickness. The material will be used in the One World Trade Center at Ground Zero.
To be able to use huge amounts of data, we have to understand them and before that we need to categorize them in an effective, fast and automatic manner. Two researchers have devised a type of Cluster Analysis, the ability to group data sets according to their "similarity," based on simple and powerful principles, which proved to be very efficient and capable of solving some of the most typical problems encountered in this type of analysis.
Mechanical engineers at the Babol University of Technology in Mazandaran, Iran, have turned to nature to devise an algorithm based on the survival trials faced by salmon swimming upstream to the spawning grounds to help them fish out the optimal solution to a given problem.
Inspired by anomalies that arise in certain mathematical equations, researchers have demonstrated a laser system that paradoxically turns off when more power is added rather than becoming continuously brighter. The finding could lead to new ways to manipulate the interaction of electronics and light, an important tool in modern communications networks and high-speed information processing.
Dinosaurs and mathematics do not seem like an obvious pair, but for Robert Sinclair and his Mathematical Biology Unit, they are a logical match. Sinclair was part of a team that recently published a paper reexamining the classification of a dinosaur bone found. Using his expertise in mathematics, Sinclair was able to help reclassify a single arm bone as belonging to a dinosaur family previously believed not to have existed ...
There are some 100 million other places in the Milky Way galaxy that could support complex life, report a group of university astronomers in the journal Challenges. They have developed a new computation method to examine data from planets orbiting other stars in the universe. Their study provides the first quantitative estimate of the number of worlds in our galaxy that could harbor life above the microbial level.
An historic milestone in artificial intelligence set by Alan Turing — the father of modern computer science — has been achieved. The 65 year-old iconic Turing Test was passed for the very first time by supercomputer Eugene Goostman during Turing Test 2014 held at the Royal Society in London on June 7, 2014, and organized by the University of Reading.
All men are mortal. Socrates is a man. Therefore, Socrates is mortal. Logical arguments like this one have been studied since antiquity. In the last few decades, however, logic research has changed considerably: the computer sciences were born. The success of informatics would have been impossible without the groundwork provided by logicians — and, in turn, computer sciences keep posing new interesting questions
If a bulky electrical box has to be placed at the edge of a public park, what’s the best way to conceal it so that it won’t detract from its surroundings? How about an air-conditioning condenser beside a historical building, or a portable toilet along a scenic trail?
Now at Mark 24, the NAG C Library is a collection of hundreds of user-callable mathematical and statistical functions for C and C++ programmers. It contains over 1,500 powerful algorithms that are designed to be reliable, flexible and ready-for-use from a wide range of operating systems, languages, environments and packages
Researchers have solved one aspect of the discrete logarithm problem. This is considered to be one of the 'holy grails' of algorithmic number theory, on which the security of many cryptographic systems used today is based. The team has devised a new algorithm that calls into question the security of one variant of this problem. The result discredits several cryptographic systems ...
Mathematicians have found a framework for the celebrated Rogers-Ramanujan identities and their arithmetic properties, solving another long-standing mystery stemming from the work of Indian math genius Srinivasa Ramanujan. The findings, by mathematicians at Emory University and the University of Queensland, yield a treasure trove of algebraic numbers and formulas to access them.
Scientists studying graphene’s properties are using a new mathematical framework to make extremely accurate characterizations of the two-dimensional material’s shape. Graphene, discovered in 2004, is a one-atom-thick sheet of graphite. The mathematical framework being used is known as discrete differential geometry, which is the geometry of two-dimensional interlaced structures called meshes.
As modern computer systems become more powerful, utilizing as many as millions of processor cores in parallel, Intel is looking for new ways to efficiently use these high performance computing (HPC) systems to accelerate scientific discovery. As part of this effort, Intel has selected Georgia Tech as the site of one of its Parallel Computing Centers.
