Cover Story: In the current respiratory COVID-19 pandemic, airborne virus-laden aerosols are considered as the primary route of transmission of SARS-CoV-2 pathogen. Staying in the air for a long enough time (minutes or hours), aerosol particles can be transferred over a long distance in an indoor environment to be inhaled by a susceptible host. Face cover masks are currently treated as the best accepted personal protective equipment (PPE) in mitigating aerosol dispersal. The material barrier of masks makes it uncomfortable to wear them in certain situations. The individually portable air curtain is a non-material barrier based, highly effective, PPE dynamically displacing the trajectories of infected particles that would otherwise be inhaled by an uninfected individual from reaching the surface and the openings of the host’s protected face.

The application of the CPT (charge-conjugation, parity, and time reversal) theorem to an apple falling on Earth leads to the description of an anti-apple falling on anti–Earth (not on Earth). On the microscopic level, the Dirac equation in curv...

In this paper, we give new formulas for calculating the self-inductance for circular coils of the rectangular cross-sections with the radial and the azimuthal current densities. These formulas are given by the single integration of the elementary fun...
