According to a new study in Europe there are just five types of social network user. Indeed, the types apply equally as well to any social networking site, these are: Sporadics, Lurkers, Socializers, Debaters, and Actives. As social networking sites become more and more prevalent and more and more a part of our daily lives (viz 600 million Facebook users [...]Post from: David Bradley's Sciencetext Tech TalkDoes it matter what kind of online networker you are?

While robots aren’t yet conquering the world and won’t be anytime soon, they’re finally learning to walk, and in the near future, the kind of bipedal locomotion that’s a major part of what makes humanoid robots such an enormous engineering and maintenance challenge, may get a lot easier. And not only are they learning how [...]... Read more »

I am a coauthor on a new paper in PLoS Computational Biology I thought I would promote here. The full citation for the paper is:
PhylOTU: A High-Throughput Procedure Quantifies Microbial Community Diversity and Resolves Novel Taxa from Metagenomic Data (doi:10.1371/journal.pcbi.1001061).
The paper discusses a new software program "phylOTU" which is for phylogenetic-based identification of "operational taxonomic units", which are also known as OTUs. What are OTUs? ........ Read more »

In a recent study the conclusion about social networking sites and teens was that 93% of teens and young adults go online, compared to only 38% of adults over 65 years of age. It is surprising that 7% of 12-29 year olds still don’t use social networking sites. Twitter is the exception because it’s the [...]

I used to laugh at those TV series and movies where crime investigators could take a surveillance camera photo, however fuzzy and blurred, and enhance its resolution beyond belief to the point where every possible (and impossible) detail becomes visible.

Glasses are very useful structural materials, because they are strong. You can stand on a glass table without it breaking. But once you put too much stress on a glass it breaks. Steels on the other hand are much tougher — which means that they show a much stronger resistance to fracture: rather than suddenly [...]... Read more »

Video games might cause aggressive behavior,1 and they may contribute to childhood obesity,2 but recent research by Daphne Bavelier and her colleagues at the University of Rochester suggests that playing video games can have at least one benefit: they enhance visual attention.

Oscar uses a Maximum Entropy Markov Model (MEMM) based on n-grams. Peter Corbett has written this up (doi:10.1186/1471-2105-9-S11-S4). So, it basically is statistics once more. If you really want a proper bioinformatics education, so do your PhD at a (proteo)chemometrics department.
N-grams are word parts of n characters. For example, the trigrams of acetic acid include ace, cid, tic, eti, and aci. N-grams of length four include acid, etic, and acet. The MEMM assigns weights to these n-grams, a........ Read more »
