Rehabilitation of Patients after Ischemic Stroke Using Transcranial Direct Current Stimulation

45 patients in the acute period of ischemic stroke, aged 39–71 years were examined. All patients underwent: a study of neurological and somatic status, with verification of neurological deficit according to the NIHSS scale , to assess impairment of consciousness and coma, the Glasgow scale, to assess the degree of motor and daily activity using the Rankin and Barthel scale , to assess the recovery of motor deficit after a stroke, the APAT test was used . The use of TES in patients with stroke, regardless of the electrode application area, improves cognitive functions in naming objects, performing speech functions, which is accompanied by an increase in patients' motivation for rehabilitation and treatment and is reflected in an improvement in their quality of life

Superhyperfine interactions in Ce3+ doped LiYF4 crystal: ENDOR measurements

The first observation of the resolved Mims electron-nuclear double resonance (ENDOR) spectra from the nearby and remote nuclei of 19F and 7Li nuclei on impurity Ce3+ ions in LiYF4 crystal is reported. It shows that LiYF4:Ce3+ system can be exploited as a convenient matrix for performing spin manipulations and adjusting quantum computation protocols while ENDOR technique could be used for the investigation of electron-nuclear interaction with all the nuclei of the system and exploited for the electron-nuclear spin manipulations.Comment: 4 pages, 2 figures, 1 Table.

Inhomogeneity of the intrinsic magnetic field in superconducting YBa2Cu3OX compounds as revealed by rare-earth EPR-probe

X-band electron paramagnetic resonance on doped Er3+ and Yb3+ ions in Y0.99(Yb,Er)0.01Ba2Cu3OX compounds with different oxygen contents in the wide temperature range (4-120)K have been made. In the superconducting species, the strong dependencies of the linewidth and resonance line position from the sweep direction of the applied magnetic field are revealed at the temperatures significantly below TC. The possible origins of the observed hysteresis are analyzed. Applicability of the presented EPR approach to extract information about the dynamics of the flux-line lattice and critical state parameters (critical current density, magnetic penetration depth, and characteristic spatial scale of the inhomogeneity) is discussedComment: 17 pages, 5 Figures.

Evaluation of Erosion Intensity and Dynamics Using Terrestrial Laser Scanning

© 2018, Pleiades Publishing, Ltd. A new method of instrumental measurement of the intensity of rill and linear erosion on slopes by the method of terrestrial laser scanning is proposed. This method was tested on four plots in 2012–2016 with the use of Trimble™ GX, Trimble™ VX, and Trimble™ TX8 laser scanners. The terrestrial laser scanning is characterized by a high precision and rapidity, which could not be previously achieved by other devices. It has a number of advantages: registration of various types of erosion of temporary water streams; measurements from a distance without the disturbance of the studied surface and providing the safety of works; and calculations of morphometric parameters of slope using a high-precision digital model of topography. The given examples show that this approach may be applied to assess the denudation-accumulative balance of the moved soil material on slopes, to determine the dynamics of amount of deposits on different parts of a slope as a result of different kinds of surface runoff, and to identify spatial regularities of the formation of the network of rills and gullies. In addition, laser scanning makes it possible to perform an integral assessment of the combined impact of the entire combination of exogenous processes developed on slopes and affecting the soil cover. The observations on test plots showed a rather great role of autumn rains in the total soil loss from erosion. The data obtained were used as the basis for the elaboration of practical recommendations concerning the survey organization and monitoring of erosion with the use of laser scanning

Estimates of slope erosion intensity utilizing terrestrial laser scanning

Copyright © 2014 IAHS Press. Despite the large variety of methods for estimating slope erosion intensity, it is still difficult to obtain accurate erosion rates. Therefore, our goal was to develop a method to provide accurate estimates of sheet and rill erosion intensities, and evaluate denudation quantities due to abrasion, landslides and talus processes using a high-precision laser scanning system (Trimble® GX). Differential maps between all stages of surveying and TIN-models were built directly on point clouds in "Trimble® RealWorks" software. Inspection and cross-section tools were used for detailed study of ground movements on the slope surface and the development of linear erosion forms. A new method for accurate estimates of the erosion has been developed using terrestrial laser scanning techniques. It makes it possible to assess the denudation-accumulation balance on erosive slopes, determine the dynamics of the volume of material moved on different parts of the slope in various surface runoff events, and identify spatial regularities forming rill washouts

Assessment of the intensity of slope erosion using terrestrial laser scanning

© 2016,International Journal of Pharmacy and Technology. All rights reserved.Assesment of the intensity of soil erosion is a crucial challenge of modern geomorphology. Despite the fact that there are a number of methods of studying exogenous processes,such as assessment of intensity by rill wash,pins method,radioactive tracer method,the problem of quantitative assessment of erosion intensity in various sections of a temporary hydrographic net remains still unsettled. Terrestrial laser scanning (TLS) allows overcoming the difficulties associated with low productivity and accuracy of traditional methods. Operations on erosion intensity assessment were carried out on two key sites within the city of Kazan in 2013-2015,and on two sites in Vysokogorsky district of Kazan in 2015. The results of the measurements show the predominance of erosion (-37.69 m3/ha on the first and -86.53 m3/ha on the second key site) on the slope in Kazan and the predominance of accumulation (53.45 m3/ha on the first and 71.66 m3/ha on the second key area) in Vysokogorsky district of Kazan. The results obtained suggest the possibility of applying the TLS for a quantitative and qualitative assesment of the intensity of denudation,and determination of the process flow patterns. The method allows evaluating integrally the cumulative effect of the entire complex of exogenous processes,flowing on the slopes

Coherent manipulation of dipolar coupled spins in an anisotropic environment

We study coherent dynamics in a system of dipolar coupled spin qubits diluted in solid and subjected to a driving microwave field. In the case of rare earth ions, anisotropic crystal background results in anisotropic g tensor and thus modifies the dipolar coupling. We develop a microscopic theory of spin relaxation in transient regime for the frequently encountered case of axially symmetric crystal field. The calculated decoherence rate is nonlinear in Rabi frequency. We show that the direction of static magnetic field that corresponds to the highest spin g-factor is preferable in order to obtain higher number of coherent qubit operations. The results of calculations are in excellent agreement with our experimental data on Rabi oscillations recorded for a series of CaWO4 crystals with different concentrations of Nd3+ ions.Comment: 16 pages, 9 figure
