The electrons found in Dirac materials are notorious for being difficult to manipulate due to the Klein phenomenon and absence of backscattering. Here we investigate how spatial modulations of the Fermi velocity in two-dimensional Dirac materials can give rise to locali...

The use of impact attenuators (IA) is important for vehicles as they absorb the kinetic energy exerted from the car crashes to protect the drivers from any possible injuries. Under the framework of the Formula Student (FS) competition, we investigate various designs of ...

Fat fraction quantification and assessment of its distribution in the hepatic tissue become more important with the growing epidemic of obesity, and the increasing prevalence of diabetes mellitus type 2 and non-alcoholic fatty liver disease. At 3Tesla, the multi-echo, c...

In this paper we introduce a notion of spectral approximation for directed graphs. While there are many potential ways one might define approximation for directed graphs, most of them are too strong to allow sparse approximations in general. In contrast, we prove that f...

Founding and determination of thermodynamic functions related to solid often geologic materials is traced showing interactions between Czech Professor F. Wald and Russian R.S. Kurnakov and D.S. Korzhinski? in the early definition of phases and characterization of partly...

This paper is based on real application whose task was to recognize characters printed on metal ingots. The problem is that the surface of ingots is very uneven - ingots are either hot, or cut by rough instrument, the printing machine can be worn down, etc. Therefore, t...

This work introduces a novel method of low-temperature (70 °C) ambient-air plasma treatment for the rapid fabrication of mesoporous titania/polysiloxane thin films in perovskite solar cells. The me...

The paper presents experimental results concerning the variation of microplastic limit (MPL) during fatigue as determined by the measurement of changes in inductanceLof specimens made from normalized low-C steel CSN 411375. Some indications have been obtained that MPL v...

The endogenous cannabinoid system (ECS) works as pro-homeostatic and pleiotropic signaling system activated in a time- and tissue-specific way during physiological conditions, which include cognitive, emotional and motivational processes. It is composed of two G protein...
