A Viral Infection Risk Indoor Simulator (VIRIS) has been developed to quickly assess and compare mitigations for airborne disease spread. This agent-based simulator combines people movement in an indoor space, viral transmission modelling and detailed architectural design, and it is powered by topologicpy, an open-source Python library. VIRIS generates very fast predictions of the viral concentration and the spatiotemporal infection risk for individuals as they move through a given space. The simulator is validated with data from a courtroom superspreader event. A sensitivity study for unknown parameter values is also performed. We compare several non-pharmaceutical interventions (NPIs) issued in UK government guidance, for two indoor settings: a care home and a supermarket. Additionally, we have developed the user-friendly VIRIS web app that allows quick exploration of diverse scenarios of interest and visualisation, allowing policymakers, architects and space managers to easily design or assess infection risk in an indoor space.

Apple's Face ID does not recognize users wearing a surgical mask, forcing them to type in their passcode or remove the protective gear to unlock the smartphone. Researchers have now shared a hack that trains the technology to accept your face with or without a mask. The video tutorial shows a user folding a brand-new mask in half, laying it on one side of their face and going through the process of setting up the biometric system. Users can either'Reset Face ID' or choose to make their masked face an'Alternate Appearance.' Researchers have now shared a trick that train the technology, which involves snapping pictures of your face with just half of it covered by a mask. The Centers for Disease Control (CDC) has recommended that Americans consider wearing masks to limit the spread of the coronavirus that is sweeping the nation.

Americans are increasingly being spotted wearing face masks in public amid the coronavirus pandemic, as are people are around the globe. Soon, the Centers for Disease Control and Prevention (CDC) may advise all Americans to cover their faces when they leave the house, the Washington Post reported. The agency is weighing that recommendation after initially telling Americans that they didn't need to wear masks and that anything other than a high-grade N95 medical mask would do little to prevent infection any way. Research on how well various types of masks and face coverings varies but, recently, and in light of the pandemic of COVID-19, experts are increasingly leaning toward the notion that something is better than nothing. A University of Oxford study published on March 30 concluded that surgical masks are just as effective at preventing respiratory infections as N95 masks for doctors, nurses and other health care workers.
