Taking into account the functional and design features of optoelectronic devices, this paper proposes to divide the process of developing their thermal macromodels into several stages related to the idealization of the design and the purpose of isothermal volumes. The authors also considered the principle of transition to topological thermal models of structural elements of an optoelectronic device. The paper studies the features of replacing the calculations of heat transfer processes in an optoelectronic device with calculations of electrical processes in the corresponding circuits based on the electrothermal analogy. The material of this work is presented as a method of hierarchical computer modeling of thermal processes in optoelectronic devices

The paper overviews the results of computational studies of the molecular mechanisms underlying
the adaptation of model cell membranes taking place during their interaction with proteins and peptides. We
discuss changes in the structural and dynamic parameters of the water–lipid environment, the hydrophobic/
hydrophilic organization of the lipid bilayer surface (the so-called “mosaicity”), etc. Taken together,
these effects are ...

The rapid development of new microscopy techniques for cell biology has exposed the
need for genetically encoded fluorescent tags with special properties. Fluorescent biomarkers of the
same color and spectral range and different fluorescent lifetimes (FLs) became useful for fluorescent
lifetime image microscopy (FLIM). One such tag, the green fluorescent protein BrUSLEE (Bright
Ultimately Short Lifetime Enhanced Emitter), having ...

Abstract. The energy efficiency concept incorporates energy conservation and durability components involved in the operation of buildings and cost considerations pertaining to the manufacturing and installation of materials. Ceramic brickwork offers the highest reliability and durability category, is not combustible and in terms of these parameters has advantages over other insulated facade cladding systems. Improving ...

A series of small (7- to 12-mer) amphipathic cationic peptides were designed and synthesized with the ultimate goal of creating a set of short helical peptides with broad-range bactericidal activity and good selectivity toward the bacterial cells. Activity analysis identified a lead 12-mer peptide 8b with broad spectrum activity against Gram-positive (MIC=3.1-6.2 µg/mL) and Gram-negative ...

S-acylation is a post-translational linkage of long chain fatty acids to cysteines, playing a key role in normal physiology and disease. In human cells, the reaction is catalyzed by a family of 23 membrane DHHC-acyltransferases (carrying an Asp-His-His-Cys catalytic motif) in two stages: (1) acyl-CoA-mediated autoacylation of the enzyme; and (2) further transfer of the ...

The electrons of the cosmic plasma act on spacecraft, causing the electrification of their dielectric materials. The result of the accumulation of charge is the occurrence of electrostatic discharges leading to failures in the operation of on-board radio electronics, and this phenomenon significantly reduces the duration of the active existence of spacecraft. One of the ...

Array DBMSs operate on big N-d arrays. Cellular automata (CA) work on a discrete lattice of cells, essentially on N-d arrays. CA facilitate decision support as they realistically simulate complex phenomena including road traffic, fire spread, and urban growth. Array DBMSs can bring numerous benefits to the CA domain via a ``database approach'': powerful parallelization, ...

The authors propose a new method for increasing the reliability of radio-electronic equipment, which involves obtaining deterministic reserves for thermal and associated electrical and mechanical loads of electrical components. These reserves should be used as additional indicators for calculating probabilistic reliability indicators at enterprises. The currently used method of calculating using only probabilistic laws of ...

Phenazepam (bromdihydrochlorphenylbenzodiazepine) is the original Russian benzodiazepine tranquilizer belonging to 1,4-benzodiazepines. There is still limited knowledge about phenazepam's metabolic liver pathways and other pharmacokinetic features. To determine phenazepam's metabolic pathways, the study was divided into three stages: In silico modeling, in vitro experiment (cell culture study), and in vivo confirmation. In silico modeling was performed ...
