A Dipole Vortex Model of Obscuring Tori in Active Galaxy Nuclei
The torus concept as an essential structural component of active galactic
nuclei (AGN) is generally accepted. Here, the situation is discussed when the
torus "twisting" by the radiation or wind transforms it into a dipole toroidal
vortex which in turn can be a source of matter replenishing the accretion disk.
Thus emerging instability which can be responsible for quasar radiation flares
accompanied by matter outbursts is also discussed. The "Matreshka" scheme for
an obscuring vortex torus structure capable of explaining the AGN variability
and evolution is proposed. The model parameters estimated numerically for the
luminosity close to the Eddington limit agree well with the observations.Comment: 17 pages, 11 figures, version of this paper is published in Astronomy
Report
KiDS-SQuaD: The KiDS Strongly lensed Quasar Detection project
New methods have been recently developed to search for strong gravitational
lenses, in particular lensed quasars, in wide-field imaging surveys. Here, we
compare the performance of three different, morphology- and photometry- based
methods to find lens candidates over the Kilo-Degree Survey (KiDS) DR3
footprint (440 deg). The three methods are: i) a multiplet detection in
KiDS-DR3 and/or Gaia-DR1, ii) direct modeling of KiDS cutouts and iii)
positional offsets between different surveys (KiDS-vs-Gaia, Gaia-vs-2MASS),
with purpose-built astrometric recalibrations. The first benchmark for the
methods has been set by the recovery of known lenses. We are able to recover
seven out of ten known lenses and pairs of quasars observed in the KiDS DR3
footprint, or eight out of ten with improved selection criteria and looser
colour pre-selection. This success rate reflects the combination of all methods
together, which, taken individually, performed significantly worse (four lenses
each). One movelty of our analysis is that the comparison of the performances
of the different methods has revealed the pros and cons of the approaches and,
most of all, the complementarities. We finally provide a list of high-grade
candidates found by one or more methods, awaiting spectroscopic follow-up for
confirmation. Of these, KiDS 1042+0023 is to our knowledge the first confirmed
lensed quasar from KiDS, exhibiting two quasar spectra at the same source
redshift at either sides of a red galaxy, with uniform flux-ratio
over the wavelength range

Who are you, Griselda? A replacement name for a new genus of the Asiatic short-tailed shrews (Mammalia, Eulipotyphla, Soricidae): molecular and morphological analyses with the discussion of tribal affinities
The first genetic study of the holotype of the Gansu short-tailed shrew, Blarinella griselda Thomas, 1912, is presented. The mitochondrial analysis demonstrated that the type specimen of B. griselda is close to several recently collected specimens from southern Gansu, northern Sichuan and Shaanxi, which are highly distinct from the two species of Asiatic short-tailed shrews of southern Sichuan, Yunnan, and Vietnam, >B. quadraticauda and B. wardi. Our analysis of four nuclear genes supported the placement of B. griselda as sister to B. quadraticauda / B. wardi, with the level of divergence between these two clades corresponding to that among genera of Soricinae. A new generic name, Parablarinella, is proposed for the Gansu short-tailed shrew. Karyotypes of Parablarinella griselda(2n = 49, NFa = 50) and B. quadraticauda (2n = 49, NFa = 62) from southern Gansu are described. The tribal affinities of Blarinellini and Blarinini are discussed.Copyright Anna A. Bannikova et al.

Physical Rehabilitation of Patients with Cerebral Blood Flow Acute Disorders in the Late Recovery Period
The purpose of this article is to substantiate, develop and evaluate the effectiveness of a physical rehabilitation
comprehensive program using functional training method for patients with cerebral blood flow acute disorders in
the late recovery period. The rehabilitation program focuses on improving the quality of life indicators according to
the International Classification of Functioning, treating movement disorders and returning patients to their previous
functional level. The ascertaining experiment involved 73 patients. The primary diagnosis was the consequences
of cerebral blood flow acute disorders lasting for at least 6 months and not more than 9 months after a stroke. The
physical rehabilitation comprehensive program was implemented amongst the patients of the experimental group
(n=35) and the control group (n=38), the latter attending a standard physical rehabilitation course in a medical institution.
The statistical analysis revealed a great number of correlations at a significant level, which is explained by the
connection between body structures and functions, activity and participation. The study proves the effectiveness
of the proposed program as compared to the traditional approaches. It ascertains that using specialized methods
based on functional training in post-stroke rehabilitation programs is the way to increase functional capacity and
improve the adaptation of stroke patients
Microstructure and magnetoresistance of Co90Fe10/Cu and Co65Fe26Ni9/Cu multilayers
Investigations of the microstructure, magnetic and magnetotransport properties of the optimized [Co90Fe10/Cu]n and [Co65Fe26Ni9/Cu] n multilayers with n = 32 prepared by magnetron sputtering are performed. These nanostructures exhibit the magnetoresistance values 83 % and 36 % at room temperature, respectively. The article presents the results of the influence of Co65Fe26Ni9 alloy on the magnetoresistance values and crystal structure of multilayers. In the periodic part of the nanostructure [Co65Fe26Ni9/Cu] n based on CoFeNi ternary alloy, besides fcc the formation of a bcc phase in the continuous boundaries around crystallites is found.

Localized shear as a quasi-plastic mechanism of momentum transfer in liquids
Two types of dispersion relations (DRs) in condensed media and associated momentum transfer mechanisms are discussed:
gapless DRs corresponding to acoustic modes and DRs with energy (or frequency) gap. Studying the viscoelastic effects in
condensed media based on the generalization of the Maxwell-Frenkel approach, the emphasis was placed on the gap states in
the momentum transfer mechanisms (GMS), when the k-gap was accompanied by qualitative changes in the DRs type. In this
paper, the gap states in the mechanisms of momentum transfer in liquids are associated with the effects of shear elasticity and
the formation of collective modes of quasi-plastic shears under conditions of the established type of critical phenomena in the
ensembles of shear defectsΒ β structural-scaling transitions. It has been found that the formation of collective shear modes,
having the character of self-similar solutions of the autosoliton type, accounts for the qualitative change in the dispersion
properties corresponding to the quasi-plastic momentum transfer mechanisms operating in the characteristic range of loading
times. The results of comparison with the data of original experiments confirm the initiation of quasi-plastic mechanisms
of momentum transfer in liquids during the formation of collective shear modes and corresponding change in dissipative
properties
Structure and magnetic properties of the Co2FeAl and Co2NiSi Heusler alloy films
The structural and magnetic properties (field dependences of the magnetization in magnetic fields of up to 6 kOe) of thin-film Co2FeAl, and Co2NiSi Heusler alloys grown by pulsed laser deposition on glass and a single-crystalline Al2O3 R-plane substrate at different growth temperatures (20, 280 and 420 Β°C) were studied. It was found that the stoichiometric composition of the films depends on the substrate temperature during growth and repeats the composition of the target for films grown at low temperatures. The films deposited on a single crystalline Al2O3 substrate have uniaxial magnetic anisotropy in the plane.
