The electron is one of the fundamental particles in nature we read about in school. Its behavior holds clues to new ways to store digital data. A new study explores alternative materials to improve capacity and shrink the size of digital data storage technologies. Specifically, the Michigan Tech team found that chromium-doped nanowires with a germanium core and silicon shell can be an antiferromagnetic semiconductor.
The first known study to explore optimal outpatient exam scheduling given the flexibility of inpatient exams has resulted in shorter wait times for magnetic resonance imaging (MRI) patients at Lahey Hospital & Medical Center in Burlington, Mass.
A new study, published today in Proceedings of the Royal Society B, shows in detail how life recovered from "The Great Dying" in comparison to two smaller extinction events. The international study team showed for the first time that this mass extinction was harsher than other events due to a major collapse in diversity. Ultimately, characterizing communities--especially those that recovered successfully--provides valuable insights into how modern species might fare as humans push the planet to the brink.
Many facets of city growth follow universal scaling laws. While this fact is well established, researchers are still searching for the why. Carlos Molinero and Stefan Thurner, researchers at the Complexity Science Hub Vienna, now offer a simple and elegant explanation: They derive urban scaling laws from 3D city geometry.
Mathematical analysis of COVID mortality rates in the US and Europe shows that second-wave mortality was often greatly reduced - particularly in wealthier European countries and the northeast of the US.
As Europe experienced its enormous second wave of the COVID-19 disease, researchers noticed the mortality rate was much lower than during the first wave. This inspired some to study and quantify the mortality rate on a country-by-country basis to determine how much the rate decreased. In Chaos, they introduce methods to study the progression of COVID-19 cases to deaths during the different waves; their methods involve applied mathematics, specifically nonlinear dynamics, and time series analysis.
A study by a research team from Nanyang Technological University, Singapore (NTU Singapore) and China's first digital-only bank WeBank has found that security, service quality and system quality are the most important factors for customers who use mobile banking.
University at Buffalo computer scientists have developed a tool that automatically identifies deepfake photos by analyzing light reflections in the eyes. The tool proved 94% effective in experiments described in a paper accepted at the IEEE International Conference on Acoustics, Speech and Signal Processing to be held in June in Toronto, Canada.
A collaboration at Harvard's Wyss Institute for Biologically Inspired Engineering and Harvard Medical School (HMS), and the CIC bioGUNE, a member of the Basque Research and Technology Alliance, in Spain, and the Luxembourg Centre for Systems Biomedicine (LCSB, University of Luxembourg) has developed a computer-guided design tool called IRENE, which significantly helps increase the efficiency of cell conversions by predicting highly effective combinations of cell type-specific TFs.
Toshiba announced a scale-out technology that minimizes hardware limitations, an evolution of its optimization computer, the Simulation Bifurcation Machine (SBM), that supports continued increases in computing speed and scale. Toshiba expects the new SBM to be a game changer for real-world problems that require large-scale, high-speed and low-latency, such as simultaneous financial transactions involving large numbers of stock, and complex control of multiple robots. The research results were published in Nature Electronics on March 1, 2021.
