Problem statement. The compensation problem of the amplitude error occurring when modeling radar targets using matrix simulators is considered. The relations that reveal the concept of this error are given. The example shows that the amplitude of the simulated echo signal differs from the amplitude of the real one.Objective. Justification of a method for correcting the amplitude error observed when simulating echo signals from radar targets using emitter matrices.Results. It is shown that when the scanning radiation pattern is oriented normal to the matrix base, the amplitude of the simulated echo signal does not depend on the angular target position. Based on this, a method was proposed to eliminate the error through pre-distortion of the echo signal amplitude. The ratio for calculating the predistortion multiplier coefficient is obtained. In the framework of a numerical experiment, the amplitude of the simulated echo signal was estimated for various angular positions of the scanning radiation pattern without taking into account predistortion and with predistortion. The experimental results confirmed the correction effectiveness.Practical implications. The results obtained allow increasing the adequacy of modeling radar objects by matrix simulators by ensuring that the amplitude of the simulated echo signal corresponds to the amplitude of the real one.

In this studies, Mg(Al)-50 vol.% SiC particle composites were fabricated by pressure infiltration with the two different matrix base materials of Mg and Mg-6Al alloy. Thermal conductivities of the two composites were compared and the effect of addition was studied using X-ray diffraction and scanning electron microscopy (SEM). The analysis of the X-ray diffraction shows that the Al-addition to the Mg causes a contraction of the Mg lattice parameters, which brings a better matching between the matrix and SiC particle. The microstructure and the fracture surface of the composite were characterized by using SEM. The alloying element Al exists mainly in the form of α solid solution, which has a uniform distribution in matrix. From calculation, the interfacial thermal barrier resistance of the Mg-6Al/SiCp composite is about one order of magnitude lower than that of the Mg/SiCp composite.

This paper challenges the concept of matrix, base or basic language used in many descriptions and models of insertional code-switching. It proposes an account based on Construction Grammar and usage-based principles. At the heart of the paper is a discussion of four problematic issues of matrix-language approaches: the unitary conception of the notion of language, the generalization that syntactic frames mirror languages, the missing independent evidence for a matrix language and the narrow scope of the models that employ this term. The proposed approach of Bilingual Construction Grammar instead operates with a more complex, usage-based concept of language affiliation and places constructions in the centre of speech production. It thus avoids too coarse global predictions in favour of construction-specific predictions. This way, the matrix-language effect can be reinterpreted as by-product of constructional processing. Instead of using the term matrix language it is thus more appropriate to speak of matrix constructions.

The authors of the paper suggested a recently developed technology of creating oil-filled composites based on aromatic polyamide Phenylone C-2. The depicted approach originates in the functional modification of the matrix base with nanomodified fillers and nanodimensional additives. The paper formulated the principles of absorption modification of mineral nanofiller for creating universal inhibitors of tribosystem or oleaginous polymer, more known as «maslyanit». It was demonstrated that the efficiency of polymer filling is enhanced by the joint application of the methods of preliminary solvent cleaning and dispersion of mineral particles to the nanodispersed state. The increase of the sorption capacity of natural and synthetic minerals was carried out by acid modification of minerals. A set of comparative tribological tests on a friction machine of Amsler II 5018 type according by a «finger-roller» scheme without external lubrication was carried out to evaluate the resistance of composite materials to abrasion at a constant specific pressure. It was found that the introduction of PFPE oil led to a significant decrease of the coefficient of friction practically in the entire loading range only in composites containing Aerosil. While the introduction of PMPS oil, in contrast, strengthened the antifriction effect of the samples, containing spinel and serpentine, in the load range of 209-720 N. The study of physical and mechanical properties of composites was carried out by NanoTest 600 complex. It was established that the samples with the addition of Arimid are characterized with the highest physical and mechanical properties. Besides, it as noted that the addition of PFPE and PMPS oils when creating oil-filled composites results in 20-25% decrease the microhardness and modulus of elasticity values. The carried out researches allowed concluding that the composite with that composition is most suitable for use in non-lubricated friction units.

Mitochondrial alterations were studied in 25 liver biopsies from patients with alcoholic liver disease. Of special interest were the morphologic resemblance of certain fine structural variations in mitochondria and crystalloid inclusions. Four types of alterations within mitochondria were found that seemed to relate to cytoplasmic crystalloids.Type 1 alteration consisted of localized groups of cristae, usually oriented in the long direction of the organelle (Fig. 1A). In this plane they appeared serrated at the periphery with blind endings in the matrix. Other sections revealed a system of equally-spaced diagonal lines lengthwise in the mitochondrion with cristae protruding from both ends (Fig. 1B). Profiles of this inclusion were not unlike tangential cuts of a crystalloid structure frequently seen in enlarged mitochondria described below.
