Spectra of persistent photoconductivity (PPC) in HgTe/CdHgTe quantum well (QW) heterostructures of both n- and p-types have been investigated at T = 4.2 K. PPC is shown to be either positive (increase of carrier concentration in QW) or negative depending on a wavelength of the illumination. As a general trend, PPC maxima in n-type sample correspond to PPC minima in p-type samples and vice versa. It is discovered that in p-type samples the illumination with certain wavelengths results in the freezing out of free carriers in QWs but not in the conversion of the conductivity type. The latter indicates a significant role in the PPC mechanism of the built-in electric field that is switching off at the QW neutralization.

AbstractThe solution to the problem of calculating the magnetostatic interaction energy of domain walls in uniaxial magnetics with a uniform magnetization distribution inside the domains is given. In carrying out the calculations, the principle of equivalent currents is used, assuming a uniform distribution of magnetization and its representation by equivalent currents flowing along the domain walls and along the surface. Analytical expressions for the mutual induction of two rectangular conductors with an arbitrary aspect ratio have been obtained. Results may be helpful in determining equilibrium configurations of domain structures in magnetic elements of spintronic devices, magnetic sensors and magnetic memory.

AbstractThe magnetic properties (field range H = 0–50 kOe, temperature range T = 3–300 K), and structural features of a sodium-doped carbon composite material based on fullerene C_60 and thermally exfoliated graphite (TEG) are studied. The material is obtained with different ratios of the components by sintering at a pressure of 7 GPa and T = 600°C, at which it is found that significant amorphization of the crystal lattice of the initial C_60 occurs. The dia-, para-, and ferromagnetic components ( M _D, M _PM, and M _FM) were separated from the total magnetic moment of the samples under study. It is found that a sodium dopant has no effect on the magnetic properties of the composite. Analysis of the M _PM( H ) field dependences by using the Brillouin function for the fullerene-containing sample (i.e., without TEG) makes it possible to determine the quantum number of the total angular momentum of paramagnetic (PM) centers. Its value is found to be J = 1, which corresponds to elementary magnetic moment μ_PM = 2μ_B of a PM center. The concentration of PM centers is estimated at the level of N _PM ≈ (2–5) × 10^18 g^–1 for most samples, including the material without TEG. The introduction of TEG into the initial composition and an increase in its proportion in the composite leads to a strong increase in the magnetic moment, which is explained by an increase in both the J value and the concentration of PM centers.
Механизм упрочнения ультрамелкозернистого алюминия после отжига

Published: September 2019

A theoretical model is proposed that describes the mechanism of hardening of ultrafine-grained aluminum, obtained by severe plastic torsion deformation, after low-temperature annealing. In the framework of the model, hardening is realized due to the sequential transformation of the grain-boundary dislocation structure. In particular, plastic deformation occurs through the emission of lattice dislocations from triple junctions of grain boundaries containing pile-ups of grain-boundary dislocations, the subsequent sliding of lattice dislocations in the bulk of the grain, and the formation of walls of grain-boundary dislocations climbing along opposite grain boundaries. The energy characteristics and critical stresses for the emission of lattice dislocations are calculated. The theoretical dependences of the flow stress on the plastic deformation are plotted, which show good qualitative and quantitative agreement with experimental data.

AbstractA simple method of pyrolysis of an aerosol solution of yttrium, aluminum, and cerium nitrates with the addition of urea or citric acid, followed by brief annealing, is developed to obtain a highly dispersed aluminum–yttrium garnet powder that demonstrates intense photoluminescence in the visible light region. Characterization of the synthesized samples (photoluminescence spectra, X-ray diffraction analysis, Raman spectra) showed that intense photoluminescence is achieved only in a narrow window of process conditions, namely, the concentration of nitrate solution and the concentration of citric acid or urea. The photoluminescence intensity increases upon annealing synchronously with an increase in the crystallite size, which, along with the optimal cerium concentration (~0.5 at %), is a determining factor for obtaining high-quality samples. The synthesized powders had intense photoluminescence and high optical perfection, as evidenced by the observation of whispering gallery modes.

Modeling of the structure formation of hexagonal diamond from graphite and cubic diamond was performed using the density functional theory method. The transformation of orthorhombic AB graphite into hexagonal diamond can occur as a result of uniaxial compression at pressures above 61 GPa. For the formation of hexagonal diamond from AA graphite, the pressure must exceed 57 GPa. Another possible way to obtain hexagonal diamond is uniaxial compression of cubic diamond at pressures from 300 to 380 GPa. The data of theoretical calculations were used to interpret the diffraction data obtained as a result of X-ray diffraction and electron microscopic analysis of natural and synthetic diamond-like materials. It was found that crystals with the ideal cubic and hexagonal structure are not contained in diamond-like carbon materials, and their structure is characterized by random packing of molecular layers.

A variety of types for formal determination of one of the main parameters of field emission systems - the emission area was investigated. Using hemisphere on a cylindrical post model built using the COMSOL Multiphysics software package the relationship between known types of emission area estimation was shown. The corresponding values of emission currents were calculated. It was shown that the formal emission area (the ratio of the total current to the current density at the top) provides only ~ 75% of the emission current value. The effect of the anomalous behavior of the effective emission area (intercept of the trend line of current-voltage characteristics) is obtained when the voltage level changes in standard Fowler-Nordheim coordinates. A method for an experimental estimate of the field emission area using the modified Fowler-Nordheim coordinates ln (I/U^(2-η/6)) vs 1/U is proposed. The method is applied to the analysis of field emission data of a multi-tip nanocomposite emitter with carbon nanotubes.

Abstract: Films of amorphous silicon reinforced with crystalline copper silicide inclusions were tested as anode material in liquid lithium-ion cells. The films were made by the method of layer-by-layer magnetron deposition of amorphous silicon and copper, followed by low-temperature (100 ÷ 200 ° C) annealing of the structure. During the tests, the anodes revealed the effect of long-term intensive growth of their reversible capacity. To describe the effect, a phenomenological model is proposed, based on the counter-migration of silicon and copper atoms in a non-uniform field of elastic mechanical stresses arising during the cycling of a lithium-ion cell.

The possibility of selective detection of NO2 in the air starting with a concentration of 1 ppm by means of sensors based on thin films of Au/WO3:Au when replacing the heating by the irradiation of the diode with the wavelength of 400 nm of maximum intensity of radiation is shown. Activation of photodesorption by irradiation reduces the response times of sensors under the influence of NO2 by an order of magnitude. It was found that the effect of high humidity in the conditions of irradiation of sensors at room temperature leads to an increase in response to NO2, due to the appearance of additional adsorption centers. The lack of sensor response to reducing gases and the change in the oxygen concentration in the gas mixture is caused by photodesorption of chemisorbed O2- when interacting with holes that generated under exposure of irradiation in the near-surface area of WO3.

Pyelonephritis in Pregnancy: modern draining tactics
Authors: Levchenko V. V. , Morgun Р. P.
Published: September 2019

Many publications in foreign and domestic papers are devoted to pyelonephritis in pregnancy. At the same time, aspects of the upper urinary tract (UUT) drainage, indications / lack of indications, and the duration of UUT drainage during kidney infections in pregnant women are bypassed. Etiological treatment of this pathology is well described in the European Association of Urology guidelines and American Urological Associations guidelines in accordance with the recommendations of the Food and Drug Administration (FDA). However, there are no references to the management of patients with UUT dilatation, associated with pyelonephritis in pregnant women. The Russian Clinical Guidelines for Urology (2018) also contains very brief information on this issue. Thus, each urological clinic of the Russian Federation has formed its own views on the draining tactics for pyelonephritis in pregnant women, which our colleagues have been following for years and decades. This publication presents an analysis of the literature sources focusing on the current state of the problem of pyelonephritis in pregnancy and the «neсessity» of the UUP drainage. It is intended to initiate a review of the established «tradition» and avoid a significant number of catheter and stent-related complications.

Authors: Flors-Sidro José Javier , Househ Mowafa , Abd-Alrazaq Alaa , Vidal-Alaball Josep , Fernandez-Luque Luis , Sanchez-Bocanegra Carlos Luis
Published: September 2019

BACKGROUND

Mobile health has become a major vehicle of support for people living with diabetes. Accordingly, the availability of mobile apps for diabetes has been steadily increasing. Most of the previous reviews of diabetes apps have focused on the apps’ features and their alignment with clinical guidelines. However, there is a lack of knowledge on the actual compliance of diabetes apps with privacy and data security guidelines.

OBJECTIVE

The aim of this study was to assess the levels of privacy of mobile apps for diabetes to contribute to the raising of awareness of privacy issues for app users, developers, and governmental data protection regulators.

METHODS

We developed a semiautomatic app search module capable of retrieving Android apps’ privacy-related information, particularly the dangerous permissions required by apps, with the aim of analyzing privacy aspects related to diabetes apps. Following the research selection criteria, the original 882 apps were narrowed down to 497 apps that were included in the analysis.

RESULTS

Approximately 60% of the analyzed diabetes apps requested potentially dangerous permissions, which pose a significant risk to users’ data privacy. In addition, 28.4% (141/497) of the apps did not provide a website for their privacy policy. Moreover, it was found that 40.0% (199/497) of the apps contained advertising, and some apps that claimed not to contain advertisements actually did. Ninety-five percent of the apps were free, and those belonging to the “medical” and “health and fitness” categories were the most popular. However, app users do not always realize that the free apps’ business model is largely based on advertising and, consequently, on sharing or selling their private data, either directly or indirectly, to unknown third parties.

CONCLUSIONS

The aforementioned findings confirm the necessity of educating patients and health care providers and raising their awareness regarding the privacy aspects of diabetes apps. Therefore, this research recommends properly and comprehensively training users, ensuring that governments and regulatory bodies enforce strict data protection laws, devising much tougher security policies and protocols in Android and in the Google Play Store, and implicating and supervising all stakeholders in the apps’ development process.
Social media and peer-to-peer support for individuals with health care needs and their caregivers: a scoping review (Preprint)
Authors: Kelly Katherine , Doucet Shelley , Luke Alison , Azar Rima , Montelpare William
Published: September 2019

BACKGROUND

Individuals with health care needs and their caregivers require substantial informational and emotional support. Providing this support is a major challenge for care providers, who are often not able to adequately address barriers and may not be aware of available services and programs. Online P2P support offers an accessible and inexpensive source of support; however, the breadth of these supports on social media has not been previously documented.

OBJECTIVE

This study was a scoping review of research examining the use of peer-to-peer support on social media by individuals with health care needs and their caregivers.

METHODS

This review used the PRISMA-SR method to search for articles from 1997 to 2019.

RESULTS

A total of 94 articles were included. Patients and caregivers use many social media websites for P2P interaction, including: Facebook (n = 19), Twitter (n = 7), and YouTube (n = 6). Providing and receiving informational and emotional support were important uses of social media for P2P support; however, the specific needs and experiences of patients and caregivers appeared to change as knowledge regarding the condition(s) improved. Despite the many benefits associated with participating in online P2P groups, concerns related to ethics, privacy, and the potential to spread misinformation are outlined as risks associated with its use.

CONCLUSIONS

This study revealed that patients and caregivers engage in P2P support on social media to receive informational and emotional support from peers, despite known risks and limitations. Social networking websites were revealed to be particularly suited for P2P support communication.

El mundo se encuentra en una transición energética, lo que trae como consecuencia el surgimiento de tecnologías para contrarrestar la dependencia de los derivados de petróleo en la movilidad vehicular. En respuesta a esto, se presentan los vehículos eléctricos como una alternativa ecológica para el desplazamiento cotidiano de los seres humanos. Se estableció como objetivo determinar el impacto de conectar y cargar vehículos eléctricos en la redde distribución, para ello se utilizó la herramienta de simulación Power System Simulator (PSS/ADEPT) y hojas de cálculos, en donde se realizaron corridas de flujos de carga a diferentes escenarios de penetración vehicular, evaluando en cada caso parámetros eléctricos como cargabilidad y caída de tensión en los conductores troncales y transformadores de los circuitos seleccionados. Los resultados arrojados en las simulaciones permiten afirmar que la infraestructura actual de los circuitos seleccionados no está apta para soportar una penetración considerable de vehículos eléctricos, donde en circuitos como el EMBA-105 a un 10 % de penetración vehicular eléctrica las pérdidas permisibles fueron superadas. Con estos resultados se pudo detectar cuáles circuitos de la red de distribución eléctrica seleccionados pudieran colapsar con la entrada masiva de la movilidad eléctrica.

On the classification of revolutions
Authors: Shults E. E.
Published: September 2019

The article considers one of the fundamental challenges in the theory of revolution - classification of revolutions. The author analyzes the four most popular features of revolutions that are used to define their types: “revolution from above”, “revolution from below”, “popular revolution” (the marker of the real revolution “from below”), “passive revolution” and “conservative revolution”. All these concepts have a common methodological basis, are closely interrelated in definitions and have the same problems of being used for classifying revolutions. The author examines the principles of introducing these terms and the possibility of their application for classifying revolution by asking two questions: 1) does the classification (and the definition) cover all known social-political revolutions; 2) does the classification (and the definition) allow to consider as revolutions quite different phenomena just similar to revolutions in a number of external features. The main problem of the contemporary discourse is systematization of revolutions according to the above ‘names’ that are accepted as classifying definitions. Moreover, these “new types of revolutions” are added to the existing classifications, which creates confusion, blurs the boundaries of the “revolution”, and allows other social-political phenomena - radical and mass protests, reforms and coups d'état - to be named “revolutions”. The concepts “revolution from above”, “revolution from below”, “popular revolution”, “passive revolution” and “conservative revolution” are socially significant and can be used in everyday discourse, perhaps also in the social-political space (which, however, causes difficulties), but are not scientific terms and cannot be grounds for the scientific classification of revolutions.
The dynamics of the value orientations of the Kuban youth
Authors: Khagurov T. A. , Ostapenko A. A.
Published: September 2019

The article presents the results of a three-year sociological study of the causes of social tension among the youth in Kuban as a polyethnic region. Based on the results of the survey of high school students, university students and young workers, the authors consider the youth’s attitudes to the current government, priorities of state policy, events in Ukraine and Syria, assess the state of interethnic relations in the North Caucasus and the role of Cossacks in Kuban. The article emphasizes that the inconsistency of worldviews and attitudes of the Kuban youth to these issues increased in 2017, i.e. the potential for conflicts on national and political grounds increased, which lead to the growth of social activity of participants in both patriotic actions and social protests. Today, the rejuvenation of social protests is obvious for more and more schoolchildren and teenagers take part in them. There is a growth of both the youth support for state patriotism and radical anti-state protests, and in general the number of the youth indifferent and detached from social processes declines. There is a danger of polarization and radicalization of the youth and accumulation of latent conflict potential. The state patriotic education aiming to ensure the traditional value of sacrifice for the country is eroded by the propaganda of liberal individualism and consumerism which deny such a value; the promotion of volunteerism and mutual aid comes into conflict with the ideas of leadership and competitiveness, and the values of interethnic and inter-religious friendship and respect - with the ideas of interethnic and interfaith tolerance. The return to traditional values proclaimed by the state faces the westernization trends, which determines the youth’s worldview inconsistency.

OS LIMITES DA REPRESENTAÇÃO E DO POLÍTICO: um diálogo entre os debates da judicialização da política no Brasil e o pensamento de Carl Schmitt
Authors: Anjos Isabele Sales dos
Published: September 2019

Os debates acerca da relação entre a esfera política e a jurídica tem ocupado grande parte da agenda de pesquisa nos campos das Ciências Sociais e do Direito. Isto se deve às proporções em que as dinâmicas imbricadas nesta relação alcançaram no modus operandi dos processos democráticos dos Estados modernos de direito, que ficaram conhecidas e popularizadas pelo fenômeno denominado “Judicialização da Política”. No Brasil a discussão ganhou destaque nas décadas subsequentes ao estabelecimento da Constituição de 1988, quando as decisões do trabalho do Judiciário ao interpretar a Constituição passam a exercer um papel central no processo de democratização. Este trabalho visa apresentar um diálogo entre os debates sobre judicialização da política produzidos no Brasil e as contribuições teóricas de Carl Schmitt presentes em sua crítica ao liberalismo.

The impact of the larger number of non-linear consumers on the quality of electricity
Authors: Agic Enver , Sljivac Damir , Agic Bakir
Published: September 2019

Theoretically this paper will explain the formation of higher harmonic
components in the electricity network, their causes, consequences on
consumers and the ways of their elimination. Transformer role in the Dyg
connection will be explained on the concrete example. For a specific example
the waveform of primary (R) phase at 10 kV voltage level, the current of the
secondary (r) phase and the neutral conductor at the 0.4 kV voltage level
will be determined as shown in the concrete example in the work. Harmonic
content will be determined up to 15 harmonics and the effective value of all
these currents (phases R and r). THD for current of primary (R) phase and
secondary (r) fase will be calculated. In this paper, the dimensional
three-phase filter is set to eliminate the maximum harmonic component of
current of the primary (R) phase on the 10 kV side of the transformer. The
waveform, the corresponding harmonic content for the current and THD of
primary (R) phase will be determined. Additional measures have been proposed
to reduce the THD. Another parallel filter has been realized to eliminate
the second by size harmonic components of primary (R) phase current. It will
also compare THD for primary (R) phase as in the previous cases. For the
total duration of the simulation, the used time is Tstop = 0.1 sec. All of
the above simulations will be realized in the MATLAB/PSB program package
and simulation models will be displayed.
External validation of prostate health index-based nomogram for predicting prostate cancer at extended biopsy
Authors: Stojadinovic Milorad , Pantic Damnjan , Stojadinovic Miroslav
Published: September 2019

Introduction/Objective. Prostate Health Index (PHI)-based nomograms were created by Lughezzani et al. (2012) and Zhu et al. (2015) for predicting prostate cancer (PCa) at extended biopsy. The aim of the study was to externally validate two nomograms in the Serbian population. Methods. This retrospective study comprised 71 patients irrespective of digital rectal examination (DRE) findings, with prostate-specific antigen level < 10 ng/ml, who had undergone prostate biopsies, and PHI testing. Data were collected in accordance with previous nomograms predictors. Independent predictors were identified by using logistic regression. The predictive accuracy was measured by the area under the receiver operating characteristic curve (AUC). The calibration belt was used to assess model calibration. The clinical utility was measured by using decision curve analysis (DCA). Results. There were numerous differences in underlying risk factors between validation dataset and previously available data. Analysis demonstrated that the DRE and PHI were independent predictors. AUCs for both nomograms, in patients with normal DRE had shown to have a good discriminatory ability (77.2?86.2%). In the entire population AUC of nomogram had exceptional discrimination (92.9%). Zhu et al. nomogram is associated with lower false positive predictions. The calibration belt for Zhu et al. nomogram was acceptable. Our DCA suggested that both nomograms are likely to be clinically useful. Conclusion. We performed external validation of two PHI-based nomograms predicting the presence of PCa in both the initial and the repeat biopsy setting. The PHI-based nomograms displayed adequate accuracy and justifies its use in Serbian patients.
Problems of European values in media policy
Authors: Milutinovic Irina
Published: September 2019

Using critical and analytical method, this article explores the status and
challenges of the fundamental values in the single European approach to
media policy. The aim of the research is to discuss the functionality of
defined values: freedom of expression, media pluralism and public interest
30 years after the adoption of the first common regulations in a media
field. In the first part of the paper the European values are perceived as
(1) conceptual heritage and (2) postulated norms of public policy. The
second part of the research focuses on the problems of implementing defined
values in (1) commercial media and (2) public media service sector. We
conclude that normative values that have been rooted in the contemporary
European media policy lose their authority facing the challenges of economic
and political interests. Two main causes of this process are: institutional
deficit of European media policy and divergent goals of its actors, at
European institutions as well as in national arenas.
Do Gender Diversity Recommendations in Corporate Governance Codes Matter? Evidence from Audit Committees
Authors: Sultana Nigar , Cahan Steven F. , Rahman Asheq
Published: September 2019

Motivated by two opposing views, the limited supply view and the discrimination view, we examine the impact of gender diversity guidelines on the strength of the association between the presence of female audit committee members and audit quality. The limited supply view predicts that the effect of female audit committee members on audit quality would decrease after the guidelines were issued because they increased the demand for women directors without a commensurate increase in the supply of qualified women directors. The discrimination view predicts this relation would increase after the guidelines were issued since some firms would have abandoned their suboptimal hiring practices that favored men over better qualified women, resulting in higher quality firm-director matches as opportunities for women increase. Consistent with the limited supply view, we find that the positive association between audit committee gender diversity and audit quality weakened after gender diversity guidelines were introduced in Australia.
