Oxygen and sulfide in ocean sediments can be consumed biologically over long spatial distances by way of filamentous bacteria in electron-conducting sheaths. To analyse observations, a mathematical model of these filamentous sulfur-oxidising bacteria was developed, including electrical conduction between reactive zones. Mechanisms include Nernst–Planck diffusion and migration of ions coupled with...
In the article on hand, two types of a non-actuated assistive device which should assist persons suffering tremor disease are presented. The device should help patients in the everyday life situation of drinking and replace devices currently used, such as feeding cups.
With prolonged intense exposure of an optical beam on the ZnTe crystal, the problem of crystal photodamage becomes increasingly relevant. In reducing the risk of damage, practically this has meant a decrease in applied optical power density. The heating effects with a reduced power density are investigated.
Scattering is a major problem in precise measurement of quasi-optical parameters of material samples. In this paper, we review some popular scattering mitigating techniques and propose a novel method that allows calculating true absorption spectra for samples with unknown thickness and granularity.
We investigated dual-color mid-infrared quantum cascade lasers. We found that due to gain competition mid-infrared modes tend to start lasing in higher order lateral modes. The mid-infrared mode with the lower threshold current reduces population inversion for the second laser with the higher threshold current due to stimulated emission. A theoretical model describing this effect was developed, which...
