The motion of a semi-infinite cylindrical net with a mass at one end is examined. The cylindrical net, with a mass at one end, is initially stretched. Addressing the problem of wave propagation in deformable filament systems, accounting for significant deviations from their original rectilinear shape, presents considerable mathematical complexity, as the equations of motion constitute a system of nonlinear partial differential equations. The solution, derived using characteristic equations, reveals the occurrence of traveling waves. This solution is constructed by satisfying conditions at the point of contact between the net and the load. The results are presented in the form of graphs and tables. [ABSTRACT FROM AUTHOR]

A new class of active organic crosslinking agents for the vulcanization of NBR based on halogenmethyl-containing compounds has been found, allowing improvement significantly in the rheological and structural parameters of NBR. Gel content and Mooney viscosity in binary systems after plastification on rollers were studied. The sol fraction of cross-linked NBR (SKN-40+TCMCC) was found to be characterized by a bimodal MWD. Abnormally high value of W/ns of sol fractions is associated with the bimodal nature of their MWD and indicates the presence of gel in the elastomer. The value of η of the sol fractions in cross-linked NBR was found to be insignificant. The sol fraction of cross-linked HCPX elastomer was shown to have lower values of the specified parameters and lower content of highmolecular-weight fractions. The branching density ρ of macromolecules of sol fraction of cross-linked NBR was 1.90-2.3·10-3, i.e. on average corresponded to one monomer unit and two hundred branching nodes per molecule.

This article discusses a case study involving a patient who presented with abnormal findings during a scan at 26 weeks of pregnancy, including an affected periventricular zone and cataract. The patient's previous child had died due to brain hemorrhage. Fetal MRI confirmed the presence of brain hemorrhage and affected periventricular zone. Whole exome sequencing (WES) revealed a mutation in the JAM 3 gene, which is involved in the formation and maintenance of tight junctions in the brain's blood vessels. Mutations in this gene have been linked to various neurological disorders, including brain hemorrhage. Further research is needed to fully understand the relationship between JAM 3 gene mutations and brain hemorrhage. [Extracted from the article]

This work presents the results of a study of the photoelectric properties of single crystals of the TlGa x In 1 − x Se2 system of solid solutions based on TlInSe2 with high photo and tensile sensitivity and switching properties with memory and TlGaSe2 with high photosensitivity in the visible and infrared regions of the spectrum. Single crystals of the above alloys were grown by the Bridgman–Stockbarger methods. Investigated alloys correspond in x = 0 , 0.1, 0.2, 0.3, 0.4, 0.7, 0.8, 0.9, 1 compounds. It was revealed that these alloys are photosensitive materials, and with a decrease in x from 1 to 0, a shift of the spectral characteristic maxima from 0.57 μ m to 1.35 μ m is observed. The specific resistance at 77–300 K and the bandgap of the investigated phases have been determined. It was found that with an increase in the content of Ga in the composition of solid solutions, the bandgap increases from 1.23 eV to 2.15 eV. [ABSTRACT FROM AUTHOR]
