Manufacturers Unite Online Amid Global Medical Supply Shortage

In addition to wreaking havoc on economies and livelihoods worldwide, the COVID-19 pandemic has also led to a global shortage of personal protective equipment (PPE). The World Health Organization has called for an 40% increase of manufacturing of PPE, such as face masks, face shields, respirators and body suits, since healthcare workers rely on these products to protect themselves as they treat the infected. In a press conference on March 23, California Governor Gavin Newsom estimated his state alone would…

Caring for seniors during COVID-19 pandemic — ScienceDaily

Older adults are at elevated risk for complications from COVID-19 and are dying at a higher rate than younger patients. In light of these concerns, Regenstrief Institute and Indiana University School of Medicine scientist Kathleen Unroe, M.D., MHA, and colleagues lay out guidelines and best practices for healthcare providers and family caregivers who are providing care for seniors during the COVID-19 pandemic. Their recommendations are published in the Journal of Geriatric Emergency Medicine. “Our senior patients need additional measures of…

Computer science alumnus finalist for Mark Twain Fellowship

Mizzou Engineering alumni Luke Guerdan is a finalist for the 2020 Mark Twain Fellowship. The MU-sponsored fellowship supports Mizzou alumni pursuing graduate study abroad. The recipient is granted significant financial support for his or her studies. Guerdan, who earned degrees in computer science and psychology at MU, plans to pursue a master’s degree at Cambridge University in England this fall. He is one of five finalists and the only finalist from the College of Engineering. The virtual award ceremony, hosted…

Deploys at Slack – Several People Are Coding

By Michael Deng and Jonathan Chang Deploys require a careful balance of speed and reliability. At Slack, we value quick iteration, fast feedback loops, and responsiveness to customer feedback. We also have hundreds of engineers who are trying to be as productive as possible. Keeping to these values while growing as a company means continual refinement of our deployment system. We had to invest in greater visibility and reliability in order to accommodate the amount of work being done. This…

Migrating from VPN to Access

With so many people at Cloudflare now working remotely, it’s worth stepping back and looking at the systems we use to get work done and how we protect them. Over the years we’ve migrated from a traditional “put it behind the VPN!” company to a modern zero-trust architecture. Cloudflare hasn’t completed its journey yet, but we’re pretty darn close. Our general strategy: protect every internal app we can with Access (our zero-trust access proxy), and simultaneously beef up our VPN’s…

Double-walled nanotubes have electro-optical advantages — ScienceDaily

One nanotube could be great for electronics applications, but there’s new evidence that two could be tops. Rice University engineers already knew that size matters when using single-walled carbon nanotubes for their electrical properties. But until now, nobody had studied how electrons act when confronted with the Russian doll-like structure of multiwalled tubes. The Rice lab of materials theorist Boris Yakobson has now calculated the impact of curvature of semiconducting double-wall carbon nanotubes on their flexoelectric voltage, a measure of…

On-Call Reliability from Electric Test Device

The widespread introduction of affordable, energy-efficient electrified vehicles (including electric and hybrid cars) is essential for meeting ambitious government CO2 emissions targets. And, ultimately, it will create a pathway to a transportation system not based on carbon fuels. The maximum driving range of an electric vehicle is determined by the amount of energy that’s contained in the individual lithium-ion battery cells of the car’s battery pack. These cells are connected in series and parallel arrangements to provide the high currents and high voltage needed to power the electric engine.  While the energy density of the Li-ion battery cell has more than…

Using Cloudflare to secure your cardholder data environment

As part of our ongoing compliance efforts Cloudflare’s PCI scope is periodically reviewed (including after any significant changes) to ensure all in-scope systems are operating in accordance with the PCI DSS. This review also allows us to periodically review each product we offer as a PCI validated service provider and identify where there might be opportunities to provide greater value to our customers. Building trust in our products is one critical component that allows Cloudflare’s mission of “Helping to build…

On the Road to Le Mans

The Le Mans 24-hour race is legendary. The aim of the race is to cover as many laps as possible within the 24 hours, with three drivers alternating. Thanks to a pneumatic operated controls system on the car using Festo technology, disabled and able-bodied drivers can now compete in the race using exactly the same car. Throttle, gear, changing, clutch and braking: During a car race the arms and legs of the drivers are usually in continuous use. Not so…

Worldwide scientific collaboration unveils genetic architecture of gray matter — ScienceDaily

The cerebral cortex is the relatively thin, folded, outer “gray matter” layer of the brain crucial for thinking, information processing, memory, and attention. Not much has been revealed about the genetic underpinnings that influence the size of the cortex’s surface area and its thickness, both of which have previously been linked to various psychiatric traits, including schizophrenia, bipolar disorder, depression, attention deficit hyperactivity disorder (ADHD), and autism. Now, for the first time, more 360 scientists from 184 different institutions —…
