The flexible compound materials of test objects (type test patterns) to adjust the aviation optical equipment for the Earth remote sensing obtained by the method of ink-jet printing on the banner fabric have been studied. The quantitative regularities of changes in the optical and mechanical properties have been determined, which allow predicting the maintenance of the operational characteristics of the type test pattern.

We study the asymptotic behavior of the number of paths of length N on several classes of infinite graphs with a single special vertex. This vertex can work as an ‘entropic trap’ for the path, i.e. under certain conditions the dominant part of long paths becomes localized in the vicinity of the special point instead ...

Based on the random phase approximation, we develop a molecular theory of self-coacervation in zwitterionic polymer solutions. We show that the interplay between the volume interactions of the monomeric units and electrostatic correlations of charged groups on a polymer backbone can result in liquid-liquid phase separation (self-coacervation). We analyse the behavior of the coacervate phase ...

Многие проблемы создания отрасли беспилотной авиации связаны с принципиальной новизной нарождающейся индустрии беспилотных полетов и именно поэтому не могут быть решены силами отдельных компаний, тем более небольших, составляющих основу этой сферы бизнеса. По сути, задача состоит в формировании новой отрасли и нахождении субъектов и механизмов организации взаимодействия участников новой отрасли между собой и с государственными органами. ...

Synthetic cationic polymers represent a promising class of delivery vectors for gene therapy. Here, we employ atomistic molecular dynamics simulations to gain insight into the structure and properties of complexes of DNA with four linear polycations: polyethylenimine (PEI), poly-l-lysine (PLL), polyvinylamine (PVA), and polyallylamine (PAA). These polycations differ in their polymer geometries, protonation states, and ...

Abstract: Polymer dielectrics subjected to intense radiation fluxes exhibit a radiation-induced
conductivity (RIC). Polyimide is a good dielectric with excellent mechanical and thermal properties
featuring high radiation resistance currently widely used in the spacecraft industry. Its RIC has
been extensively studied in several laboratories. The purpose of the present study is to make a
direct measurement of the RIC ...

In this paper we investigate the eigenvalue statistics of exponentially weighted ensembles of full binary trees and p-branching star graphs. We show that spectral densities of corresponding adjacency matrices demonstrate peculiar ultrametric structure inherent to sparse systems. In particular, the tails of the distribution for binary trees share the 'Lifshitz singularity' emerging in the one-dimensional localization, ...

We have investigated the radiation-induced conductivity (RIC) in Kapton-like polymers in which it increases with an accumulating dose at large dose rates and long irradiation times. Such a behavior is very useful for spacecraft applications as it allows mitigating the spacecraft charging problems. Also, we studied ordinary polymers whose RIC steadily falls after reaching an ...
