Antarctica's ice sheet spans close to twice the area of the contiguous United States. Its land boundary is buttressed by massive, floating ice shelves extending hundreds of miles out over the frigid w...
Tropical rainforests are often described as the “lungs of the earth,” able to essentially inhale carbon dioxide from the atmosphere and exhale oxygen in return. The faster they grow, the more they mit...
Ecologists have long observed predators pursue disproportionately more of a plentiful prey species, and less of scarce prey, but change to the latter if it becomes relatively more abundant. Known as “...
Raising further questions about privacy on the internet, researchers from Princeton and Stanford universities have released a study showing that a specific person's online behavior can be identified b...
An international team of researchers, including Carnegie Mellon University’s Rachel Mandelbaum, has shown that the relationship between galaxy clusters and their surrounding dark matter halo is more c...
The references [9, 3, 1] treat timing attacks on RSA with CRT and Montgomery’s multiplication algorithm in unprotected implementations. It has been widely believed that exponent blinding would prev...
Using a new technique to analyze 52 years of international conflict, researchers suggest that there may be no such thing as a “democratic peace.” In addition, a model developed with this new techniqu...
We provide evidence that breaking low-exponent RSA cannot be equivalent to factoring integers. We show that an algebraic reduction from factoring to breaking low-exponent RSA can be converted into an ...
Simultaneous voluntary contractions of antagonistic pairs (co- contraction) produce resistive forces that act against each other (Maeo et al., 2013c). It has been reported that a training program in w...
The aim of the present study was to verify the applicability of anaerobic work capacity (AWC) determined from the critical power model in elite table tennis players. Eight male international level tab...
We explored multiyear linear trends in nutrient concentrations, nitrogen (N) : phosphorus (P) ratio, and phytoplankton biomass within the 37-yr, whole-ecosystem nutrient enrichment experiment in Lake ...
A new comprehensive analysis of global market and policies aimed at stemming climate change says that even if all current or proposed major policies take maximum effect, they will be insufficient to a...
Second language writing textbooks for teachers are typically full of advice concerning techniques and activities to use in class, but they rarely tell teachers what things not to do. The purpose of th...
