How computers push on the molecules they simulate
Because modern computers have to depict the real world with digital representations of numbers instead of physical analogues, to simulate the continuous passage of time they have to digitize time into small ...
New study examines record of football teams after coaching changes
Fire the coach? Not so fast says a new study of elite college football teams.
New statistical method offers automatic mitotic cell detection for cancer diagnosis
(Phys.org)—Scientists have developed a statistical image analysis method which can assist in the grading of breast cancer by automatically segmenting tumour regions and detecting dividing cells in tissue samples.
Researcher develops computational text analysis method made possible regardless of language or domain
The Internet is awash with text. Databases swell larger and larger by the minute. How can the vast amount of textual data be systematically analysed and managed, as the number of languages, domains, styles ...
Scientists launch international study of open-fire cooking and air quality
Expanding its focus on the link between the atmosphere and human health, the National Center for Atmospheric Research (NCAR) is launching a three-year, international study into the impact of open-fire cooking ...
Researchers explore elections and voting behaviour with physics
Statistical physics has began to inch itself into the territory of social and human sciences in the past decade. Vast and complex social networks have particularly gained popularity among physicists. Now ...
Techniques used to infer pathways of protein evolution found unreliable
A key assumption that biologists have relied on widely over the past quarter-century in studying the evolution of protein molecules is "highly questionable," according to an article published in the November issue of BioScience.
Mathematics and fine art: Digitizing paintings through image processing
The current trend to digitize everything is not lost on fine art. Documenting, distributing, conserving, storing and restoring paintings require that digital copies be made. The Google Art Project, which brings art from galleries ...
Researchers use new statistical method to show fraudulent voting in Russian election
New research could help winemakers with 'stuck' batches
(Phys.org)—Batches of wine that get "stuck" or slowed during the fermentation process pose a big problem for winemakers, costing them time, money and a lot of ruined batches.
Researchers devise more accurate method for predicting hurricane activity
Researchers from North Carolina State University have developed a new method for forecasting seasonal hurricane activity that is 15 percent more accurate than previous techniques.
New model shows dramatic global decline in ratio of workers to retired people
A new statistical model predicts that by 2100 the number of people older than 85 worldwide will increase more than previously estimated, and there will be fewer working-age adults to support them than previously expected.
In search of the key word: Bursts of certain words within a text are what make them keywords
Human beings have the ability to convert complex phenomena into a one-dimensional sequence of letters and put it down in writing. In this process, keywords serve to convey the content of the text. How letters ...
Maths experts question key ecological theory
Mathematicians at the University of York in the UK and the University of Canterbury in New Zealand say they have disproved a widely accepted theory underpinning the operation of complex networks of interactions in the natural ...
