Explorations of Mathematical Models in Biology with Maple

February 10, 2015 9:29 am | by John A. Wass, Ph.D. | Articles | Comments

The author of this wonderful text delivers a brief, easy-to-absorb, yet very comprehensive text on modeling real-world data with Maple. Maple is software for performing mathematics, with a none-too-steep learning curve. In the introduction, the author is quick to point out that this is neither a detailed textbook of mathematical modeling, nor Maple. It is, however, a very well-written manual of introductory modeling and use of Maple.

Similar Statistics Play Role in Decision Making and World War II Code Breaking

Statistical decision making resembles a process Alan Turning's team did in Bletchley Park to work out the settings of German enigma machines. In order to make use of the large clicking machine, Turing's team analyzed pairs of randomly intercepted German messages, aligned them one above the other to accumulate evidence from letter pairs until they reach a threshold level of certainty that the messages were sent on identical enigma machine.

Supercomputing Reveals Genetic Code of Cancer

February 2, 2015 12:46 pm | by Yngve Vogt, University of Oslo | News | Comments

Cancer researchers must use one of the world's fastest computers to detect which versions of genes are only found in cancer cells. Every form of cancer, even every tumor, has its own distinct variants. A research group is working to identify the genes that cause bowel and prostate cancer, which are both common diseases. There are 4,000 new cases of bowel cancer in Norway every year. Only six out of 10 patients survive the first five years.

Scientists using supercomputers found genes sensitive to cold and drought in a plant help it survive climate change. The computational challenges were daunting, involving thousands of individual strains of the plant with hundreds of thousands of markers across the genome and testing for a dozen environmental variables. Their findings increase basic understanding of plant adaptation and can be applied to improve crops.

We're Two Minutes Closer to Doomsday

January 23, 2015 2:49 pm | by Seth Borenstein, AP Science Writer | News | Comments

The Bulletin of the Atomic Scientists says Earth is now closer to human-caused doomsday than it has been in more than 30 years because of global warming and nuclear weaponry. But other experts say that's way too gloomy. The advocacy group, founded by the creators of the atomic bomb, moved their famed "Doomsday Clock" ahead two minutes on January 22, 2015. It said the world is now three minutes from a catastrophic midnight.

Optimizing Optimization Algorithms: How to Get the Best Results

January 23, 2015 2:36 pm | by Larry Hardesty, MIT | News | Comments

Optimization algorithms, which try to find the minimum values of mathematical functions, are everywhere in engineering. Among other things, they’re used to evaluate design tradeoffs, to assess control systems, and to find patterns in data. One way to solve a difficult optimization problem is to first reduce it to a related but much simpler problem, then gradually add complexity back in ...

The Power of Regular Expressions

January 22, 2015 10:49 am | by Mark A. Anawis | Blogs | Comments

A.J. Jacobs wrote: “I think there's something to the idea that the divine dwells more easily in text than in images.” Since there has been an explosion in the amount of text, sacred and secular, available to anyone with an Internet connection, the need for processing tools has grown. Regular expressions can be used to extract specific text from documents due to their ability to replace many lines of code with as little as one line.

Book Review: Applied Bayesian Modelling, 2nd Edition

January 13, 2015 8:59 am | by John A. Wass, Ph.D. | Articles | Comments

This is not a text for the novice. However, for those math/statistics aficionados, there is much to be had. The book’s great strength lies in two areas: the first is Peter Congdon’s generation of an excellent bibliography of the most modern techniques available, and the other is his (slightly) more straightforward explanations of the strengths and weaknesses of these techniques and suggestions for optimizing the results.

By analyzing the light of hundreds of thousands of celestial objects, astronomers have created a unique map of enigmatic molecules in our galaxy that are responsible for puzzling features in the light from stars, called diffuse interstellar bands. DIBs have been a mystery ever since they were discovered in 1922 — exactly which of the many thousands of possible molecules are responsible for these features?

2015 Promises Major Milestones and Demands for Change

Despite the fact that industries won’t change working processes unless there is a mandatory need to do so, major milestones are expected in 2015 in the battle to adopt data and standardization in our scientific community. The need for deployment of these integration standards to enable efficient sharing of knowledge across our internal and external partners is re-enforced by regulatory bodies.

Big Data Analysis Reveals Shared Genetic Code between Species

December 18, 2014 11:32 am | by Mike Williams, Rice University | News | Comments

Researchers have detected at least three instances of cross-species mating that likely influenced the evolutionary paths of “old world” mice, two in recent times and one in the distant past. They think these instances of introgressive hybridization are only the first of many needles waiting to be found in a very large genetic haystack. The finding suggests that hybridization in mammals may not be an evolutionary dead end.

Although there are a diverse range of applications for predictive analytics in R&D, two common basic requirements are data and insight. Data may be generated by running experiments/analyses, or re-applied from previous work when available. Insights come from application of knowledge — both explicitand tacit. There are a variety of roles for informatics in predictive analytics...

Sophisticated New Statistical Technique helps Map Species' Genetic Heritage

December 12, 2014 5:50 pm | by Liz Ahlberg, University of Illinois | News | Comments

Where did the songbird get its song? What branch of the bird family tree is closer to the flamingo — the heron or the sparrow? These questions seem simple, but are actually difficult for geneticists to answer. A new, sophisticated statistical technique can help researchers construct more accurate species trees detailing the lineage of genes and the relationships between species.

New Theory could Yield More Reliable Communication Protocols

December 12, 2014 5:23 pm | by Larry Hardesty, MIT | News | Comments

Communication protocols for digital devices are very efficient but also very brittle: They require information to be specified in a precise order with a precise number of bits. If sender and receiver — say, a computer and a printer — are off by even a single bit relative to each other, communication between them breaks down entirely.

Applications for Randomness

November 17, 2014 8:49 am | by Mark A. Anawis | Blogs | Comments

The mathematician, Robert R. Coveyou, said: “The generation of random numbers is too important to be left to chance.” Random numbers are used in sampling, simulations, modeling, data encryption, gambling and even musical composition. A random number is one selected from a set of equally possible values. Any sequence of random numbers must be statistically independent of the others.
