We study the polarization and dispersion properties of gluons moving within a weakly magnetized background at one-loop order. To this end, we show two alternative derivations charged fermion propagator in weak field expansion use expression to compute lowest order magnetic correction gluon tensor. explicitly that, spite its cumbersome appearance, tensor is transverse as required by gauge invari...

This paper is devoted to the analysis of existing eVTOL flying vehicles and consideration capabilities flight controller based on STM32F722 microcontroller, as well evaluation characteristics various sensors devices study their using BetaFlight firmware. The main result this work development a prototype (prototype) transportation platform future, for which both hardware software parts vehicle s...

Withstanding 3.5 billion years of genetic drift, the canonical genetic code remains such a fundamental foundation for the complexity of life that it is highly conserved across all three phylogenetic domains. Genome engineering technologies are now making it possible to rationally change the genetic code, offering resistance to viruses, genetic isolation from horizontal gene transfer, and preven...

We present some insights on the use and interpretation of resilience ideas that arose in a conference on “Society’s Resilience in Withstanding Disaster.” Three points in particular have relevance for those interested in resilience in social-ecological systems: (1) Time as a threshold vs. avoiding quick fixes; (2) Trading risks: specified vs. general resilience; (3) Response origination: buildin...

Traditional radiation hardened or “rad hard” parts are generally considered to be capable of withstanding the most severe space environments. In fact, these devices are designed and fabricated with the specific goal of enduring the harshest space radiation environments. And while they have tremendous radiation capabilities, these parts are more expensive and less advanced that today’s commercia...

We study memory devices consisting of single-walled carbon nanotube transistors with charge storage at the SiO(2)/nanotube interface. We show that this type of memory device is robust, withstanding over 10(5) operating cycles, with a current drive capability up to 10(-6) A at 20 mV drain bias, thus competing with state-of-the-art Si-devices. We find that the device performance depends on temper...
