Mathematicians at the University of Kent, with input from the University of Sheffield, have established that current restrictions on academics applying for research grants are causing major problems, harming smaller institutions and minorities in the process. To reduce the time and money spent evaluating applications, many funding bodies responded by restricting the number they receive.
An international team of researchers, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has discovered that folding is an efficient strategy to incorporate large-area monolayer graphene films on polymer composites and that doing so improves mechanical reinforcement. Their work has been published in the prestigious journal, Advances Materials.
Anyone who shops online is familiar with those 'top-rated' products or services that rise to the top of their search on e-commerce intermediary sites like Amazon or Expedia. So, do those rankings really help those products or services get sold? According to a new study, the answer is, 'yes' and 'no.'
A new study, published in the Journal of Wind Engineering & Industrial Aerodynamics, based on wind tunnel research on a peloton of 121 cyclists may explain why so few 'breakaways' in professional cycling races, like this year's Tour de France, are successful.
Global fossil fuel emissions would have to be reduced by as much as 20 percent more than previous estimates to achieve the Paris Agreement targets, because of natural greenhouse gas emissions from wetlands and permafrost, new research has found. The additional reductions are equivalent to five to six years of carbon emissions from human activities, according to a paper led by the UK's Centre for Ecology & Hydrology.
As of 2013, there were 7.8 million researchers globally, according to UNESCO. This means that 0.1 percent of the people in the world professionally do science. Their work is largely financed by governments, yet public officials are not themselves researchers. To help governments make sense of the scientific community, Russian mathematicians have devised a researcher typology. The authors initially identified three clusters, which they tentatively labeled as "leaders," "successors," and "toilers."
By 2015, e-book sales had grown to comprise 20 percent of all book sales. To ensure e-book sales did not undermine print sales, publishers frequently delayed the digital publication date for several weeks after the print edition has been released. However, new research in the INFORMS journal Management Science found that delaying e-book sales does not lead to increased print sales, and can result in significantly fewer e-book sales once the digital version is made available.
Engineers work in quantifiable realism -- an object exists and can be measured. Sometimes, though, the certainty of the object and how it will behave wavers. Researchers from the Automatic Control and System Dynamics Laboratory at the Technische Universität Chemnitz in Germany are starting to close the gap between reality and mathematical uncertainty. They published an analysis of the discrepancy between mathematical proofs, algorithms, and their implementations in control systems with real, measurable outcomes.
Researchers from Zhejiang University in China have developed a new way to boost the performance of automated systems such as energy plants, airplanes and electronics. Prof. Su and his team have designed an algorithm that computes the feasible set using constraints represented by geometric shapes. The program can quickly determine the angle of the inner connections within each shape, resulting in the feasible set or all possible actions with ease.
Unlike humans, crops in a field can't move to air conditioning to endure a heat wave. Scientists in Australia are working to understand how heat waves impact wheat.
