Anisotropy and delayed relaxation of the anomalous Hall effect in GdFeCo/Ir/GdFeCo synthetic ferrimagnets
Authors: Bakhmetiev M. V.  , Talantsev A. D.  , Koplak O. V.  , Morgunov R. B.
Published: March 2023

In synthetic ferrimagnets with perpendicular anisotropy GdFeCo/Ir/GdFeCo, the dependence of the hysteresis loops of the anomalous Hall resistance and the characteristics of the loops on the angle between the magnetic field and the plane of the sample are analyzed. The part of the anomalous Hall resistance corresponding to the spin-orbit torque has been identified. The field dependences of the resistance are sensitive to switching between the magnetic states of the two-layer ferrimagnet and they reproduce the shapes of the magnetization hysteresis loops, calculated with the interlayer exchange interaction, crystal anisotropy, and Zeeman energies at different angles between the field and sample. A slow (~30 min) magnetic relaxation of resistivity hysteresis after reorientation of the sample in magnetic field was found. Specific domain dynamics inherent in two-layer samples was revealed by Kerr microscopy. It was found that slow restoration of the resistivity hysteresis loop is due to domain propagation. Keywords: spin Hall effect, spin-orbit torque, magnetic relaxation, domain wall dynamics.

Elastic Properties of B2-NiAl with W addition: A first-principles study
Authors: Ponomareva A. V.
Published: March 2023

The effect of tungsten alloying on the elastic properties of B2-NiAl at low-temperature and high-temperature distribution of W atoms on sublattices. By means of the exact muffin-tin orbitals method in conjunction with the coherent potential approximation, the constants C11,C12,C44, Young's modulus E, shear modulus G, Cauchy pressure values, G/B ratios are calculated. Using phenomenological criteria of the correlation between ductility and elastic properties of solution phases, it has been shown that the addition of tungsten could yield improved ductility for B2-NiAl in both types of alloys. It is established that with the high-temperature distribution of W atoms on the Al sublattice, there is a loss of mechanical stability and a decrease in mechanical properties with increasing W concentration. In alloys with a low-temperature distribution of tungsten atoms between Al and Ni sites a unique combination of properties occurs: in addition to the ductility enhancement, a simultaneous increase of the elastic constants C44 and C11 and C11, shear modulus G, Young's modulus E with increasing W content is observed. The differences in the behavior of elastic constants in alloys with different types of tungsten distribution on NiAl sublattices are analyzed by calculating the density of electronic states. Keywords: NiAl, alloying elements, tungsten, elastic properties, ductility, first-principles calculations.

Authors: Eremeev I. A.  , Vorobev V.G.  , Grashchenko A. S.  , Semencha A.V.  , Osipov A. V.  , Kukushkin S. A.
Published: March 2023

Sequential stages of synthesis of SiC epitaxial films on n- and p-type Si(111) substrates in a mixture of carbon monoxide and silane are studied by X-ray diffraction (XRD) and Raman scattering methods. It was found that the elastic strain in SiC films grown on n-type Si(111) is absent in contrast to SiC films grown on p-type Si(111), where the deformations are formed and completely relaxed by the 40 min of synthesis. A dramatic change in the SiC film structure is observed on the third minute of the growth, which is associated with the formation and growth of pores in the SiC layer. Differences in the lattice constants of SiC films grown on p- and n-type Si substrates are determined and verified via analysis of the change in the curvature of SiC/Si wafers. Keywords: Silicon carbide on silicon, elastic strain, nanostructures, microstructure evolution.

The impedance spectroscopy in the temperature range 302-779 K was used to study the ionic conductivity of the Pr0.9Pb0.1F2.9 nanoceramics, obtained by cold pressing of the powder, mechanically synthesized from components of PbF2 and PrF3. The studied material is the solid solution with tysonite-type structure (sp. gr. P3c1, Z=6) and lattice parameters a=7.0906(4) and c=7.2538(4) Angstrem. With increasing temperature, the conductivity of the ceramic increases from 1.9·10-5 to 6.7·10-2 S/cm, and the activation enthalpy of ion transport Delta Hsigma=0.407±0.005 and 0.345±0.005 eV at 302-502 and 502-779 K, respectively. The electrical conductivity mechanism is due to the migration of fluorine vacancies along the boundaries of nanocrystalline grains. The intragranular conductivity of ceramics is close to the electrical conductivity of a single crystal of the same composition. Cold pressed ceramics Pr0.9Pb0.1F2.9 can be used as a promising solid electrolyte in "room" fluorine-ion current sources.

Authors:  Bochkareva N. I.  ,  Shreter Y. G.
Published: March 2023

The mechanism for the influence of defects in theGaN on the efficiency of localization of electrically-injected charge carriers in the InGaN|GaN quantum well is studied using tunnel spectroscopy of deep centers. It is found that the curves of the quantum efficiency and the spectral efficiency of radiative recombination dependencies on forward bias have the shape with maximum and humps at the biases corresponding to the impurity bands of color centers in GaN. The quantum efficiency droop with increasing bias is accompanied by a blue shift of the emission spectrum. We explain these effects based on the model of carrier localization in the quantum well, which takes into account the significant contribution to the tunneling transparency of the potential walls of the quantum well from ionized deep centers and their recharging with increasing forward bias. Keywords: gallium nitride, quantum well, charge carrier localization, tunneling, quantum effeciency, color centers.

Polydiphenylenephthalide (PDP) belongs to the class of organic dielectrics, which exhibit electric conductive properties when an external electrostatic field and/or mechanical stress are applied. In this work, the transport properties of thin-film layered lead-PDP-lead structures were experimental-ly studied in a wide temperature range. At sufficiently high temperatures, the volt-ampere depend-ences are satisfactorily described in terms of the injection model of currents limited by the space charge. At temperatures below ~7.5 K, a number of samples exhibit features that can be explained by the effect of induced superconductivity in a thin film of a conducting polymer enclosed between two massive superconductors (lead). Keywords: thin films, conducting polymer, superconductivity.

A pharmacological perspective on the use of Benzylpenicillin-G in the production of veterinary medicine in Latin America
Authors: Gutiérrez Lilia , Sumano Héctor , Ocampo Luis , Nieto Agustín , Aquino Itzcoatl
Published: March 2023

Benzylpenicillin-G (BP-G) is one of human and veterinary medicine’s most widely used antibacterial drugs. It represents a large market for the Phar­maceutical Industry, and various combinations with frail pharmacological support have been made available to veterinarians. The crystalline sodium and potassium salts of BP-G and the benzathine salt of BP-G have been incorporated into many existing preparations, arguing that higher and more prolonged concentrations are obtained. However, there are not evidence published. Notwithstanding the above, these preparations are presented as sustained-release ones and capable of achieving therapeutic concentrations. There are no pharmacokinetic bases for such combinations of BP-G deriva­tives. It is unlikely that such combinations provide better serum profiles than those offered by an adequate dose of only procaine BP-G. The incorporation of the BP-G benzathine is prohibited in many countries. In Latin America, such combinations limit the amount of procaine BP-G that should be in­jected, ideally ≥ 20 000 IU/kg of body weight every 12-24 h. Within the framework of the rational use of antimicrobial drugs in veterinary medicine advanced by the World Health Organization (WHO) and based on pharma­cological considerations, it is proposed that combinations of BP-G derivatives be restricted, allowing only BP-G procaine preparations. Also, formulations of BP-G incorporating other active principles should offer solid pharmacological support. To date, combined preparations of BP-G have shown no formal pharmacological support. Based on the information presented in this review, it is feasible to conclude that the only BP-G derivative that should be available for veterinary medicine is procaine BP-G.
Tendencias contemporáneas sobre la opinio juris y la prueba material del derecho internacional consuetudinario
Authors: Casella Paulo Borba
Published: March 2023

El presente artículo tiene por objeto discutir cómo puede tener sentido el derecho internacional, a partir del estado actual de la técnica, frente a los desarrollos futuros, y qué características debe tener el mismo para hacer frente a los desafíos que plantea el surgimiento del actual contexto mundial posmoderno, interdependiente, multipolar y cada vez más complejo. La novedad en el contexto internacional actual es que, además del nivel individual de acción de los Estados, ya sea unilateral, bilateral y multilateral, existe un área creciente para la formación y el desarrollo del consenso común. En ese contexto, la opinio juris ya no debe entenderse en la actualidad como una opinión individual de uno o de ciertos Estados, sino como declaraciones colectivas, emitidas por la comunidad internacional, en su conjunto o de una parte sustancial de las mismas.

El trabajo decente desde las condiciones salariales de los docentes universitarios del sector público en Venezuela
Authors: Alvarado Diony , Bencomo Tania
Published: March 2023

El presente artículo tiene como objetivo principal analizar la figura del trabajo decente impulsada por la Organización Internacional del Trabajo, que implica tutela jurídica efectiva para el ejercicio de los derechos laborales, protección social y diálogo social, desde las condiciones salariales que poseen los docentes universitarios en Venezuela, que representan cifras que los colocan como los trabajadores peor remunerados del continente americano, por debajo del umbral de la pobreza extrema, conforme a los indicadores por ingreso registrados por la Organización de las Naciones Unidas y el Banco Mundial, condiciones que promueven el retiro y la emigración masiva de los profesores universitarios, o la asunción de la labor docente universitaria como un trabajo voluntario o no remunerado cuyos gastos operativos deben ser subsidiados con los recursos del propio trabajador. Se utilizó el diseño de investigación documental con un nivel descriptivo; se concluye que las condiciones salariales y laborales en general del personal docente universitario del sector público están totalmente alejadas de las que se podrían considerar como decentes por la OIT, y que la lucha gremial por enfrentar dicha precariedad debe asumir la conciencia gremial colectiva nacional e internacional.
NLP-Based Conversion of Telugu Scientific Terms in Telugu Medium Textbooks into English
Authors: Sowjanya G. Mohana , Bhaskari D. Lalitha
Published: March 2023

Abstract: Telugu is the native language of those who reside in the Indian states of Telangana and Andhra Pradesh. While many students in Andhra Pradesh and Telangana study in the English medium, some students study in the Telugu medium because of budgetary and other issues. Despite having many skills, Telugu medium students cannot compete with English medium students since they only learn everything in Telugu. As a result, Telugu medium students encounter some challenges when they need to study for competitive examinations, show up for interviews, and continue their education in the English language. If they learn the meaning of important and repeated Telugu scientific terms in English while studying in the Telugu medium, then they can overcome this situation. This project extracts Telugu scientific terms from Telugu textbooks and translates them into English using a frequency-based approach. An attempt was made to help them with learning English terminology in this project
A Research on Modeling of High Impedance Fault Detection for Protection of Dc Distribution System
Authors: Khan Prof. Saniya
Published: March 2023

Abstract: High ohmic resistance faults area unit troublesome to find by standard overcurrent relays principally thanks to their low current magnitudes. This paper describes a model for representing high ohmic resistance faults in electrical distribution systems. The model is predicated in a very non-linear resistance representing the high ohmic resistance path throughout this sort of faults. Supported this model, the performance of many electrical variables associated to high ohmic resistance faults is analyzed and an algorithmic rule for top ohmic resistance fault detection in electrical distribution systems is given. Field activity and pc simulations validate the high ohmic resistance fault model and therefore the projected fault detection algorithmic rule. A high ohmic resistance fault (HIF) is generated once an energized conductor (of a primary feeder) makes contact with the bottom or with neighboring objects like branch trees, overgrown vegetation, building walls, asphalt, any object to ground. Such faults area unit undetectable by standard overcurrent devices like overcurrent relays and fuses as a result of their low current magnitude. What is more, arcing accompanies high ohmic resistance faults (hifs) and represents a risk of security to folks and injury to physical infrastructure. Thus, so as to get a trustworthy detection algorithmic rule, it's necessary to possess a reliable high ohmic resistance fault model. This paper presents an analysis of the HIF trial run results and a technique for modeling hifs by considering one nonlinear resistance to represent the fault.

Este artigo objetiva responder à seguinte questão investigativa: como a criança, na aurora de sua vida, instancia, via movimentos linguístico-enunciativos, formas embrionárias e como, em sua história na linguagem, insere formas complexas do discurso, caso das narrativas, nas relações enunciativas com o outro? Para tanto, ancorado na Teoria da Linguagem de Émile Benveniste, o presente estudo investiga fatos de linguagem de uma criança acompanhada em coletas naturalísticas e longitudinais nas seguintes faixas etárias: 2 meses e 12 dias; 7 meses e 29 dias; 3 anos e 8 meses. Os resultados da análise apontam que, na constituição da história de enunciações da criança, os sentidos produzidos, na relação com outros, promovem o deslocamento da criança de formas embrionárias para formas complexas do discurso. Nesse deslocamento, enredam-se aspectos de ordem social e de ordem individual, reveladores da instauração da criança nos dois modos de ser língua:  como sistema e como discurso.

Published: March 2023

Objetivamos investigar a fluência de leitura em pessoas com síndrome de Down (sD), utilizando, para isso, o teste Cloze (TAYLOR, 1953; KLEIMAN, 1989). Nossa hipótese é a de que as especificidades da síndrome, como atraso cognitivo e de linguagem e o comprometimento de memória, fatores importantes no processamento do texto, prejudicarão a fluência de leitura e, consequentemente, a compreensão dos textos. Três pessoas com SD participaram deste estudo e foram submetidas a três testes Cloze: rígido (TAYLOR, 1953), Racional lexicais maiores e Racional lexicais menores (KLEIMAN, 1989). O teste consiste no lacunamento de um texto a ser recuperado pelo leitor. Nossos resultados mostraram que os três participantes alcançaram baixas pontuações nos três testes realizados, principalmente no Racional lexicais menores, o que evidencia baixa fluência de leitura e, portanto, comprometimento da compreensão do texto.

Published: March 2023

O objetivo do artigo é defender a existência de um conceito de ideologia em O Capital de  Marx. A hipótese é que, como ideologia em Marx e Engels é uma forma de conhecimento (ou forma de consciência) socialmente difundida que estabelece uma hierarquia de valores e orienta a ação dos indivíduos, pode-se defender a existência de um conceito de ideologia também na crítica da economia política realizada por Marx. Isso porque, como a realidade social gera um conjunto de necessidades entre as quais estão incluídas as ideias, qualquer conjunto de crenças afirmativo de determinada realidade pode ser considerado uma ideologia.
Industry classifications and environmental, social, and governance disclosure: The moderating role of CEO power
Authors: Purwantini Cornelio , Faisal Faisal , Joseph Corina , Januarti Indira
Published: March 2023

This study aims to investigate the moderating effect of chief executive officer (CEO) power on the relationship between industry classifications and environmental, social, and governance (ESG) disclosure using the legitimacy theory. Forty-eight public companies listed on the Indonesia Stock Exchange during the period 2012–2016 were analyzed via partial least squares. The results show that industry classifications have a significant effect on ESG disclosure. Specifically, companies in sensitive industries and companies for which the majority of the shares are owned by the government are likely to disclose more ESG information. Furthermore, our study also provides empirical evidence that CEO power plays a significant role in strengthening the relationship between industry classification and ESG disclosure. Surprisingly, CEOs of companies whose majority shares are owned by the government fail to demonstrate their role in encouraging higher disclosure of ESG. The managerial implication of this finding suggested that CEO power may be an effective mechanism in increasing companies’ commitments to disclose ESG activities. This study has practical implications by providing new insights into the role of CEO characteristics in the relationship between industry types and ESG disclosure for Indonesian companies.

Human activities have been a key driver of hydraulic erosion changes in northeastern China over the past 37 years
Authors: Hua Li , Tang Qi , Cai Chongfa , Jiang Long , Cai Chongfa
Published: March 2023

Northeast China is experiencing severe soil erosion, resulting in land
degradation and nutrient loss. Among them, hydraulic erosion poses the
greatest threat to food security. Combining various multi-source data,
we applied the modified soil erosion equation (RUSLE) to evaluate
hydraulic erosion modulus in Northeast China’s black soil
region(1985–2021). We used the threshold segmentation and residual
analysis method to quantify the relative roles of climate change and
human activities on hydraulic erosion. The outcomes were presented
below: (1) The yearly mean hydraulic erosion modulus was 804.78 t·km
·a and decreases significantly
with a slope of -11.114 t·km ·a
. The area with significant growth in erosion
modulus covered 23.77% of the overall area and was mainly spread in
grassland and farmland. The areas with a significant decrease in erosion
modulus covered 19.82% and were mainly spread in natural forests. (2)
In areas with significant increases in erosion, 20.39% of the total
area was attributed to anthropogenic factors and 3.38% of the total
area was attributed to natural factors. In areas where soil erosion was
significantly reduced, 17.67% and 2.15% were attributed to ecological

The creation of new genes is a major force of evolution. Despite as an
important mechanism that generated new genes, segmental duplication (SD)
has yet to be accurately identified and fully characterized in birds
because the repetitive complexity leads to misassignment and misassembly
of sequence. In addition, SD may lead to new gene copies, which makes it
possible to test the “out of testis” hypothesis which suggests genes
are frequently born with testis-specific expression. Using a
high-quality chromosome-level assembly, we performed a systematic
analysis and presented a comprehensive landscape of SDs in tree sparrow
(Passer montanus). We detected co-localization of newly expanded
genes and long terminal repeat retrotransposons (LTR-RTs), both of which
are derived from SDs and enriched in microchromosomes. The newly
expanded genes are mostly found in eight families including
C2H2ZNF, OR, PIM, PAK, MROH,
HYDIN, HSF and ITPRIPL. The large majority of new
members of these eight families have evolved to pseudogenes, whereas
there still some new copies preserved transcriptional activity. Among
the transcriptionally active new members, new genes from different
families with diverse structures and functions shared a similar
testis-biased expression pattern, which is consistent with the “out of
testis” hypothesis. Through a case analysis of the high-quality genome
assembly of tree sparrow, we reveal that the SDs contribute to the
formation of new genes. Our study provides a comprehensive understanding
of the emergence, expression and fate of duplicated genes and how the
SDs might participate in these processes and shape genome evolution.
Highly Performance Supercapacitors Based on N‑Doped Activated Carbon Derived from Shrimp Shell
Authors: ALABADI AKRAM , jumaah husam
Published: March 2023

Herein, activated porous carbon with highly surface area has been
successfully synthesized from shrimp shell (SSAC) and the graphitic
structure is slightly maintained via adjusted KOH activation conditions.
The textual structural and morphological properties of prepared-SSAC was
characterized using X-ray diffraction (XRD), X-ray photoelectron
spectroscopy (XPS), Raman spectroscopy, scanning electron microscopy
(SEM) and energy-dispersive X-ray spectroscopy (EDS). The maximum
specific capacitance 262 F g−1 at current density of 1 A g-1 and 198F
g−1 at 10 A g−1 calculated in a 6 M KOH electrolyte. Moreover, high
energy and power densities of the supercapacitor are 28.266 Wh kg-1 and
4460 W kg-1, respectively, whereas the cycle-life performance is 85.5%
after 10,000 charging−discharging cycles at 1 A g−1 measured by
galvanostatic charge–discharge (GCD) studies is not firstly attributed
to high surface area, but due to the inveterate electron-rich nitrogen
Risk of Appropriate Implantable Cardioverter-Defibrillator Therapies and Sudden Cardiac Death in Patients With Heart Failure With Improved Left Ventricular Ejection Fraction

Published: March 2023

Background The benefit of implantable cardioverter
defibrillator (ICD) therapy in patients who have heart failure with
improved left ventricular ejection fraction (LVEF) to >35%
after implantation (HFimpEF) is controversial. Methods
Databases (Ovid MEDLINE, EMBASE, Web of Science, and Google Scholar)
were queried for studies of ICD patients that reported the association
between HFimpEF and arrhythmic events (AEs), defined as the combined
incidence of ventricular arrhythmias, appropriate ICD intervention and
sudden cardiac death (primary composite endpoint). Results A
total of 41 studies and 38,572 patients (11,135 with HFimpEF, 27,437
with persistent EF <35%) were included; mean follow up was 43
months. HFimpEF was associated with decreased AEs (OR 0.39, 95% CI
0.32-0.47; annual rate (AR) 4.1% vs. 8%; P<0.01).
Super-responders (EF >50%) had a lower risk of AEs than
patients with more modest reverse remodeling (EF>35% and
<50%, OR 0.25, 95% CI 0.14-0.46; AR 2.7% vs. 6.2%;
P<0.01). HFimpEF patients who had an initial primary
prevention indication had a lower risk of AEs (OR 0.43, 95% CI
0.3-0.61; AR 5.1% vs. 10.3%; P<0.01). Among primary
prevention patients who had never received appropriate ICD therapy at
the time of generator change, HFimpEF was associated with decreased
subsequent AEs (OR 0.26, 95% CI 0.12-0.59; AR 1.6% vs. 4.8%;
P<0.01). Conclusion HFimpEF is associated with
reduced, but not eliminated, risk for AEs in patients with ICDs. The
decision for replacing an ICD in lower risk subgroups should incorporate
shared decision making based on risks for subsequent AEs and procedural
complications.
On a class of super-recurrent operators
Authors: Amouch Mohamed , Benchiheb Otmane
Published: March 2023

In this paper, we introduce and study the notion of super-recurrence of
operators. We investigate some properties of this class of operators and
show that it shares some characteristics with supercyclic and recurrent
operators. In particular, we show that if T is super-recurrent, then ?(T)
and ?p(T*), the spectrum of T and the point spectrum of T* respectively,
have some noteworthy properties.

A new constraint qualification for optimality of nonconvex nonsmooth optimization problems
Authors: Bazargan Fatemeh , Mohebi Hossein
Published: March 2023

In this paper, we study the nonconvex nonsmooth optimization problem (P) of
minimizing a tangentially convex function with inequality constraints where
the constraint functions are tangentially convex. This is done by using the
cone of tangential subdifferentials together with a new constraint
qualification. Indeed, we present a new constraint qualification to
guarantee that Karush-Kuhn-Tucker conditions are necessary and sufficient
for optimality of the problem (P). Moreover, various nonsmooth (generalized)
constraint qualifications that are a modification of the well known
constraint qualifications are investigated. Several illustrative examples
are presented to clarify the connection between nonsmooth constraint
qualifications and new constraint qualification.

Higher dimensional [m,C]-isometric commuting d-tuple of operators
Authors: Ahmed Ahmed
Published: March 2023

In this paper we recover an [m,C]-isometric operators and (m,C)-isometric
commuting tuples of operators on a Hilbert space studied respectively in
[11] and [16], we introduce the class of [m,C]-isometries for tuple of
commuting operators. This is a generalization of the class of
[m,C]-isometric commuting operators on a Hilbert spaces. A commuting tuples
of operators S = (S1,..., Sp) ? B(H)p is said to be [m,C]-isometric
p-tuple of commuting operators if ?m (S,C):= ?m j=0 (?1)m?j (m j) (?
|?|=j j!/?! CS?CS?)=0 for some positive integer m and some conjugation C.
We consider a multi-variable generalization of these single variable
[m,C]-isometric operators and explore some of their basic properties.
Some variants of normality in relative topological spaces
Authors: Raina Sehar , Das A.K.
Published: March 2023

With each topological property P one can associate a relative version of it
formulated in terms of the location of Y in X in such a natural way that
when Y coincides with X, then this relative property coincides with P.
Arhangel?skii and Genedi introduced this concept of relative topological
properties in 1989. The concept of mild normality or ?-normality was
introduced independently by Singal and Singal in 1973 and Scepin in 1972.
A few years earlier in 1969, Singal and Arya studied the concept of almost
normality. V. Za?cev in 1968 introduced the concept of quasi normal spaces
while ?-normality was studied by Kalantan in 2008. In this paper we study
these variants of normality in a relative sense.
