We published a post on work at the University of California, San Francisco, to identify existing drugs that looked like they had the potential to treat Covid, as in at a minimum reduce the severity of disease (We Found and Tested 47 Old Drugs That Might Treat the Coronavirus: Results Show Promising Leads and a Whole New Way to Fight COVID-19). But that was before the vaccine effort was far enough along to look like it was likely to bear fruit. As we’ve pointed out, the West has gone all in with the vaccine magic bullet approach, when that’s not a great public health idea, unless the goal...

 E-Mail Alexandria, Va., USA -- Carbon dioxide (CO2) is a byproduct of human metabolism and exists in high levels in exhaled air, and is therefore often used as a proxy for indoor air quality. The study "Ventilation Assessment by Carbon Dioxide Levels in Dental Treatment Rooms," published in the Journal of Dental Research (JDR), evaluated CO2 levels in dental operatories and determined the accuracy of using CO2 levels to assess ventilation rate in dental clinics. Researchers at the University of Rochester, Eastman Institute for Oral Health, N.Y., USA, conducted CO2 concentration and ventila...

For instance, "multiagent problems," a category characterized by multi-stage decision-making by multiple decision makers or "agents," has relevant applications in search-and-rescue missions, firefighting, and emergency response. Multiagent problems are often solved using a machine learning technique known as "reinforcement learning" (RL)...

200031, Researchers led by Professor Baohua Jia at Swinburne University of Technology, Victoria, Australia, Professor Cheng-Wei Qiu at National University of Singapore, Singapore and Professor Tian Lan at Beijing Institute of Technology, Beijing, China considered the generation of super-resolved optical needle and multifocal array using graphene oxide metalenses. Ultrathin and lightweight, metalenses are becoming increasingly significant for their use in photonic chips, biosensors and micro imaging systems such as smart phone cameras. Compared to conventional lenses, metalenses can improve t...

 E-Mail From power grids and telecommunications to water supply and financial systems, digital data controls the infrastructure systems on which society relies. These complex, multi-tier systems depend on layered communications to accomplish their tasks - yet every point of contact becomes a potential target, every path of information a potential weak spot for malicious actors to attack. A team of researchers from the University of Calabria in Italy has developed the first predictive control scheme that can help distributed networks with multiple agents not only identify these attacks but a...
