Indoors, outdoors, 6 feet apart? Transmission risk of airborne viruses can be quantified

E-Mail

In the 1995 movie Outbreak, Dustin Hoffman s character realizes, with appropriately dramatic horror, that an infectious virus is airborne because it s found to be spreading through hospital vents.
The issue of whether our real-life pandemic virus, SARS-CoV-2, is airborne is predictably more complex. The current body of evidence suggests that COVID-19 primarily spreads through respiratory droplets - the small, liquid particles you sneeze or cough, that travel some distance, and fall to the floor. But consensus is mounting that, under the right circumstances, smaller floating particles called aerosols can carry the virus over longer distances and remain suspended in air for longer periods. Scientists are still determining SARS-CoV-2 s favorite way to travel. ....

The Association for Computing Machinery Special Interest Group on Information Retrieval (ACM SIGIR) today announced the inception of the SIGIR Academy to honor and recognize individuals who have made significant, cumulative contributions to the development of the field of information retrieval (IR). Inductees to the Academy are the principal leaders in IR, whose efforts have shaped the discipline or industry through significant research, innovation, and/or service. Each year, a small cohort of three to five new members will be elected to the Academy. Induction is an official ACM award. ....

Argonne scientists help explain phenomenon in hardware that could revolutionize AI | US Department of Energy Science News

DOE/Argonne National Laboratory
Artificial intelligence, or AI, requires a huge amount of computing power, and versatile hardware to support that power. But most AI-supportive hardware is built around the same decades-old technology, and still a long way from emulating the neural activity in the human brain.
In an effort to solve this problem, a group of scientists from around the country, led by Prof. Shriram Ramanathan of Purdue University, has discovered a way to make the hardware more efficient and sustainable.
We re creating hardware that is smart enough to keep up (with advancements in AI) and also doesn t use too much energy. In fact, the energy demand will be cut significantly using this technology. Argonne physicist Hua Zhou ....

Dethroning electrocatalysts for hydrogen production with inexpensive alternative material

Scientists at Tokyo Institute of Technology (Tokyo Tech) discover a new electrocatalyst for the oxygen evolution reaction (OER) in electrochemical water splitting: CaFe2O4. This inexpensive, non-toxic, and easy-to-synthesize material outperforms other bimetallic OER electrocatalysts and even surpasses the benchmark set by iridium oxide, paving the way to accessible hydrogen generation for upcoming hydrogen societies. ....

Overview:
A research team at the Department of Electrical and Electronic Information Engineering, Department of Computer Science and Engineering, Department of Applied Chemistry and Life Science, and the Electronics-Inspired Interdisciplinary Research Institute (EIIRIS) at Toyohashi University of Technology has developed a lightweight, compact, Bluetooth-low-energy-based wireless neuronal recording system for use in mice. The wireless system weighs 3 with the battery, having advantages of high signal quality, good versatility, and low cost, compared to wired recording with a commercial neurophysiology system. The study was published online in ....
