A Northwestern University study of how jet lag affects Major League Baseball players traveling across just a few time zones found that when players travel in a way that misaligns their internal 24-hour clock with the natural environment and its cycle of sunlight, they suffer negative consequences. The researchers found that jet lag negatively affects the base running of home teams but not away teams and that home and away pitchers both give up more home runs when jet-lagged.
New research by ASU scientists reveals that the prehistoric Pueblo people of the American Southwest, despite not having a written language or number system, created architectural complexes using advanced geometry -- with incredible mathematical accuracy.
When should women start getting heart screenings? A new national survey by Orlando Health shows most women wait way too late.
Xiang-Gen Xia, the Charles Black Evans Professor in UD's Department of Electrical and Computer Engineering, shares his thoughts on big data in a 'Perspectives' paper published in the January 2017 issue of IEEE Signal Processing Magazine.
A team of researchers from the Polytechnic University of Bari, in Italy, are working to improve how industrial electric drives operate. They propose a new control scheme that will improve not only how the motor operates, but also how to improve how the motor interacts with other systems. The scheme is detailed in a paper published in IEEE/CAA Journal of Automatica Sinica.
The transport of heat in amorphous materials is largely determined by the behavior of phonons -- quasiparticles associated with the collective vibrations of atoms. Researchers from Georgia Tech developed a new way to calculate the heat contribution of phonons using computer simulations. Using the Stampede supercomputer at the Texas Advanced Computing Center, they modeled amorphous silicon -- glass -- providing new insights into a material that is critical for energy efficiency.
Standby upgrade programs are an innovative way for hotels to increase annual revenue by as much as 35 percent. However, new research in an upcoming edition of the INFORMS journal Manufacturing & Service Operations Management finds that the success of a standby upgrade program is directly tied to the type of guests who frequent the hotel, and the types and quantity of rooms available.
Pioneering new research has provided a fascinating new insight in the quest to determine whether temperature or water availability is the most influential factor in determining the success of global, land-based carbon sinks. The research, carried out by an international team of climate scientists including Professors Pierre Friedlingstein and Stephen Sitch from the University of Exeter, has revealed new clues on how land carbon sinks are regulated on both local and global scales.
The team have shown that 'determining whether antibiotic cycling or mixing selects best against drug resistant pathogens is not possible, even in standardized questions using mathematical models, let alone in the clinic,' according to lead author Robert Beardmore. Their work may help explain why recent clinical trials like the Saturn project -- explicitly designed to resolved the ongoing issue of high controversy (antibiotic cycling vs. mixing) -- may not work.
A new study from Vanderbilt University presents an unorthodox approach to protect the privacy of genomic data, showing how optimal trade-offs between privacy risk and scientific utility can be struck as genomic data are released for research. The framework can be used to suppress just enough genomic data to persuade would-be snoops that their best privacy attacks will be unprofitable.
