Magnetotransport measurements were carried out for YBa2Cu3O7-x (YBCO) thin films in external perpendicular magnetic fields of H. The studies were performed both for the virgin samples and for the irradiated ones. Xenon ions were used as an external irradiation. Thus we studied features of the broadening of superconducting transition in YBCO films (virgin and irradiated). The broadening of superconducting drop was analyzed depending on an external magnetic field H, as well as on an irradiation dose nD. When processing the experimental data R(H,T), we studied a criterion for determination of temperature dependence of the upper critical field Hc2(T). The criterion was analyzed depending on the defect concentration in the film corresponding to a certain value of nD. It was found out that for a virgin sample, Hc2 should be determined by the resistance level R=0.4RN inside the superconducting transition, where RN=R(T=100 K). With a gradual increase in nD, this resistance level decreases. At sufficiently high radiation doses nD>7·1012 cm-2, the Hc2(T) phase transition line should be determined by the level R~0. Keywords: thin films, HTSC, xenon ion irradiation, magnetotransport studies, broadening of the superconducting transition, upper critical field, phase transition line, Tinkham's formula, Abrikosov vortices.

Magnetic nanoparticles of magnetite with a size of ~8 nm synthesized with a different type of coating were studied by ferromagnetic resonance in the temperature range from 7 to 300 K. The features of the experimental temperature dependences of the parameters of the ferromagnetic resonance curve (the magnitude of the resonant field, line width and intensity) and their approximation allowed us to estimate the values of characteristic temperatures. Firstly, the value of the Vervey temperature and the dependence of its value on the type of coating were determined. Secondly, the temperature of transition of nanoparticles to the superparamagnetic state (blocking temperature) and the temperature range within which the magnetic structure of the outer shell of the magnetic nanoparticle is in the spin glass state are established Keywords: iron oxide nanoparticles, ferromagnetic resonance, superparamagnetism, blocking temperature.

The magnetic properties and micromagnetic structure of [Co/Pt]10 multilayer magnetic films formed by independent variation of the Co and Pt layer thicknesses have been studied. The possibility of the film magnetization parameters manipulation was shown. It is found that the micromagnetic structure of the layers is significantly modified with a change in the thickness of the layers which correlates with the magnetization data. In particular, magnetic force microscopy revealed a system of magnetic skyrmions for a number of structures. The skyrmion density was found to be dependent on the growth conditions which in turn correlates with the shape of the magnetic hysteresis loop. Changing the thickness of the Co and Pt layers makes it possible to control the density of skyrmions in the range from 0.2 to 10.5 mkm-2. Keywords: micromagnetic structure, skyrmions, CoPt films, electron beam evaporation.

Authors: Semkin S. V.  , Smagin V. P.  , Lavrushina E. G.
Published: August 2023

A method of approximate calculation of the magnetization of an Ising magnet located in an external magnetic field is proposed. This method is based on using an exact or approximate expression for the spontaneous magnetization of an Ising magnet on the same lattice. The method uses the ratio of effective fields for clusters of one and two lattice nodes. Using the proposed method for a magnet located in an external field, the dependence of magnetization on temperature and the magnitude of the external field is calculated. The proposed method is applied in the work to the solution in the mean field approximation, to the solution in the Beta approximation and to the exact solution on a square lattice; for all these solutions, critical indices characterizing the behavior of a magnet in an external field are calculated. Keywords: the Ising model, phase transitions, the influence of an external field.
SOT-MRAM Elements Based on Spin Hall Effect : Macrospin Model of Two-Step Switching Control
Authors: Ostrovskaya N.V.  , Skidanov V. A.  , Iusipova Iu. A.
Published: August 2023

The article presents the results of a qualitative study of the model of a modern magnetic memory cell, in which the spin Hall effect is used for recording. Cells of square cross-section with longitudinal anisotropy of the active layer are considered. Based on the Landau-Lifshitz-Gilbert vector equation, a mathematical model for controlling the process of writing zero and one into a cell is constructed. In the approximation of a uniform distribution of magnetization, a system of equations is derived that describes the dynamics of magnetization under the action of a magnetic field and spin current. The parameters of the qualitatively equivalent dynamics of the model are determined. It has been established that at zero currents and fields in both cases there are two main stable equilibrium positions. These equilibria, depending on the mutual orientation of the magnetization vector of the active and reference layers, correspond to zero and one, written in the cell. The transition from one cell state to another is described by solving a system of differential equations. A bifurcation diagram of a dynamical system in the variables "field-current" is constructed. It is shown that with a given configuration of the memory element, external influences transfer the magnetization to an intermediate state in the plane of the free layer, which, when the current and field are turned off, leads to writing zero or one to the memory cell. The critical switching current is estimated as a function of the applied external magnetic field. Keywords: spintronics, orbitronics, magnetization, Landau-Lifshitz-Gilbert equation, spin Hall effect, spin current, charge current, spin torque, longitudinal anisotropy, planar anisotropy.

Authors: Mittmann Gloria , Zehetner Vanessa , Hoehl Stefanie , Schrank Beate , Barnard Adam , Woodcock Kate
Published: August 2023

Background

Augmented reality (AR) has emerged as a promising technology in educational settings owing to its engaging nature. However, apart from applications aimed at the autism spectrum disorder population, the potential of AR in social-emotional learning has received less attention.

Objective

This scoping review aims to map the range of AR applications that improve social skills and map the characteristics of such applications.

Methods

In total, 2 independent researchers screened 2748 records derived from 3 databases in December 2021—PubMed, IEEE Xplore, and ACM Guide to Computing Literature. In addition, the reference lists of all the included records and existing reviews were screened. Records that had developed a prototype with the main outcome of improving social skills were included in the scoping review. Included records were narratively described for their content regarding AR and social skills, their target populations, and their outcomes. Evaluation studies were assessed for methodological quality.

Results

A total of 17 records met the inclusion criteria for this study. Overall, 10 records describe applications for children with autism, primarily teaching about reading emotions in facial expressions; 7 records describe applications for a general population, targeting both children and adults, with a diverse range of outcome goals. The methodological quality of evaluation studies was found to be weak.

Conclusions

Most applications are designed to be used alone, although AR is well suited to facilitating real-world interactions during a digital experience, including interactions with other people. Therefore, future AR applications could endorse social skills in a general population in more complex group settings.

Authors: Green James B , Rodriguez Joey , Keshavan Matcheri , Lizano Paulo , Torous John
Published: August 2023

Background

Coordinated specialty care (CSC) has demonstrated efficacy in improving outcomes in individuals at clinical high risk for psychosis and individuals with first-episode psychosis. Given the limitations of scalability and staffing needs, the augmentation of services using digital mental health interventions (DMHIs) may be explored to help support CSC service delivery.

Objective

In this study, we aimed to understand the methods to implement and support technology in routine CSC and offered insights from a quality improvement study assessing the implementation outcomes of DMHIs in CSC.

Methods

Patients and clinicians including psychiatrists, therapists, and supported education and employment specialists from a clinical-high-risk-for-psychosis clinic (Center for Early Detection Assessment and Response to Risk [CEDAR]) and a first-episode–psychosis clinic (Advancing Services for Psychosis Integration and Recovery [ASPIRE]) participated in a quality improvement project exploring the feasibility of DMHIs following the Access, Alignment, Connection, Care, and Scalability framework to implement mindLAMP, a flexible and evidenced-based DMHI. Digital navigators were used at each site to assist clinicians and patients in implementing mindLAMP. To explore the differences in implementation outcomes associated with the app format, a menu-style format was delivered at CEDAR, and a modular approach was used at ASPIRE. Qualitative baseline and follow-up data were collected to assess the specific implementation outcomes.

Results

In total, 5 patients (ASPIRE: n=3, 60%; CEDAR: n=2, 40%) were included: 3 (60%) White individuals, 2 (40%) male and 2 (40%) female patients, and 1 (20%) transgender man, with a mean age of 19.6 (SD 2.05) years. Implementation outcome data revealed that patients and clinicians demonstrated high accessibility, acceptability, interest, and belief in the sustainability of DMHIs. Clinicians and patients presented a wide range of interest in unique use cases of DMHI in CSC and expressed variable feasibility and appropriateness associated with nuanced barriers and needs. In addition, the results suggest that adoption, penetration, feasibility, and appropriateness outcomes were moderate and might continue to be explored and targeted.

Conclusions

Implementation outcomes from this project suggest the need for a patient- and clinician-centered approach that is guided by digital navigators and provides versatility, autonomy, and structure. Leveraging these insights has the potential to build on growing research regarding the need for versatility, autonomy, digital navigator support, and structured applications. We anticipate that by continuing to research and improve implementation barriers impeding the adoption and penetration of DMHIs in CSC, accessibility and uptake of DMHIs will improve, therefore connecting patients to the demonstrated benefits of technology-augmented care.
Frameworks, Dimensions, Definitions of Aspects, and Assessment Methods for the Appraisal of Quality of Health Data for Secondary Use: Comprehensive Overview of Reviews (Preprint)
Authors: Declerck Jens , Kalra Dipak , Vander Stichele Robert , Coorevits Pascal
Published: August 2023

BACKGROUND

Health care has not reached the full potential of the secondary use of health data because of—among other issues—concerns about the quality of the data being used. The shift toward digital health has led to an increase in the volume of health data. However, this increase in quantity has not been matched by a proportional improvement in the quality of health data.

OBJECTIVE

This review aims to offer a comprehensive overview of the existing frameworks for data quality dimensions and assessment methods for the secondary use of health data. In addition, it aims to consolidate the results into a unified framework.

METHODS

A review of reviews was conducted including reviews describing frameworks of data quality dimensions and their assessment methods, specifically from a secondary use perspective. Reviews were excluded if they were not related to the health care ecosystem, lacked relevant information related to our research objective, and were published in languages other than English.

RESULTS

A total of 22 reviews were included, comprising 22 frameworks, with 23 different terms for dimensions, and 62 definitions of dimensions. All dimensions were mapped toward the data quality framework of the European Institute for Innovation through Health Data. In total, 8 reviews mentioned 38 different assessment methods, pertaining to 31 definitions of the dimensions.

CONCLUSIONS

The findings in this review revealed a lack of consensus in the literature regarding the terminology, definitions, and assessment methods for data quality dimensions. This creates ambiguity and difficulties in developing specific assessment methods. This study goes a step further by assigning all observed definitions to a consolidated framework of 9 data quality dimensions.

The conflict between the Kurds and the Iraqi government in Kirkuk is not just a political conflict. This article describes how oil resources in Kirkuk can trigger conflict between the Kurds and the Iraqi government. The clash of interests between the two parties is crucial to overcome. The Kurdish referendum support group is determined to depart. Meanwhile, the government defends the Kirkuk region due to its rich natural resources. As a tool for analyzing events, the approach used is the theory of natural resources and violent conflict proposed by Ian Bannon and Paul Collier. The results indicated that Iraq's dependency and weak management of oil export commodities caused the conflict between the Kurds and the Iraqi government.  This article, compiled by applying the literature review method, aims to explain the conflict in the Kirkuk region, with natural resources as the object also the Kurds and the Iraqi government as subjects facing each other.
A Study of Overseas Construction of China National Image in Architecture Writing of Lin Yutang
Authors: Sisi Yang , Cui Dan
Published: August 2023

Lin Yutang’s writing of Chinese architecture in My Country and My People is a short chapter, but it reflects his unique studies into Chinese personality and national spirit. Through the study of Lin Yutang’s architectural writing, we can see the Chinese national spirit and image overseas. Many scholars have studied My Country and My People from different dimensions. However, literary writing of Chinese architrave hasn’t been conducted so much since the popularity of Fan Zhongyan’s Notes of Yueyang Tower. And therefore Lin’s writing is conceived to be of high significance through which the Chinese personality has been analyzed thorougly. By conparison and contrast, based on the thoughts of Chinese sages, this paper aims to (1) analyze the marrow of Chinese national spirit through Lin Yutang’s architectural writing and (2) argue how Lin Yutang through his particular English expression of architecture has successfully delivered the image of China overseas, which has thus exerted a far-reaching impact on its overseas transmission. Through exploration and interpretation of Lin Yutan’s writing, the authors aim to excavate Lin’s appropriate in-depth interpretation of Chinese spirit embedded in Chinese architecture abroad in order to modify certain misunderstandings and mistaken cognition with the expectation to gain deeper comprehension of Chinese spirit internationally.

ABSTRACT

Vocabulary is an important factor in learning a language. People cannot hear, speak, read, and write without knowing vocabulary. Likewise in learning a foreign language such as English, vocabulary plays a very important role. However, not all junior high school students learn vocabulary in English easily. This is caused by several factors including learning media that are less attractive so that children get bored quickly, teaching methods or techniques of teachers who are not creative and monotonous, and teaching and learning activities that are more dominated by teachers without involving or involving students to participate. Rumah Belajar application is one of application used in learning and found a new understanding of the new media used by the teacher in media online learning. In this research, the researcher used Classroom Action Research as the design method. The data was collected from the seventh grade which has been learned using Rumah Belajar. The sample was 24 students selected by purposive sampling. The research found that the majority of students had a positive perception of Rumah Belajar in learning based on the results of their interviews. They improved their vocabulary learning through the Rumah Belajar application in learning and found a new understanding of the new media used by the teacher in media online learning. On the other hand, some students gave the perception that online learning has obstacles affected by a poor network, the quality of the student's mobile phone, and the capacity of the online learning application.

A situação problemática que incentivou o desenrolar do tema, deu lugar à definição do subsequente problema científico: Que concepção tem sido aplicada no sistema da educação angolana: realidade e prática efetiva nas escolas primárias de Cabinda, de 2002 a 2021? Com a finalidade de contribuir na resolução do problema científico definido, foi formulada a hipótese à continuação: Capacitação de professores na concepção escolanovista de educação é possível fortalecer a realidade da prática efetiva nas escolas primárias de Cabinda. Com propósito de que constatasse-se a hipótese formulada, foi preconizado como objectivo geral: Analisar a concepção escolanovista de educação na realidade da prática efetiva nas escolas primárias de Cabinda, de 2002 a 2021. Foram aplicados os métodos do nível teórico, empírico e estatístico-matemático. A técnica utilizada foi o questionário que serviu de instrumento da recolha de dados; estes foram analisados, discutidos e interpretados tendo alcançado como resultados, os professores desconhecem a metodologia de ensino para escolas primárias, fora dos movimentos da reforma educativa; o método expositivo é a via principal porque faz-se a transmissão e avaliação somente dos conhecimentos. Entretanto, Angola precisa assumir uma metodologia que coloca o aluno como sujeito da sua aprendizagem e que o professor de ensino primário no mínimo deve ser licenciado.

Background Immunoglobulin E (IgE) is highly related to a
variety of atopic diseases, and several genome-wide correlation studies
(GWASs) have demonstrated the association between genes and IgE. In this
study, we conducted the largest genome-wide association study of IgE in
a Taiwanese Han population and aimed to elucidate the genetic
architecture of IgE. Methods Genome-wide association study was
used to discover the association between variants and IgE. Through HLA
imputation, we explored the association between HLA alleles and IgE. In
order to explore the pleiotropy relationship between IgE and atopic
diseases, we performed both global and local genetic correlation
analysis. Moreover, we divided our cohort into a training group and a
validation group to construct the polygenic risk score (PRS) of IgE and
applied it to test the risk of asthma and atopic dermatitis.
Results A total of 8 independent variants showed genome-wide
significance, and rs147642819 at 6p21.32 was the most significant signal
(p= 1.8×10 ). Seven of the loci were replicated
successfully after a meta-analysis of the Japanese population. Among all
the HLA alleles, HLA-DQB1*03:03 is the most significant allele.
The global genetic correlation showed significance between IgE and
asthma. The IgE PRS significantly correlated with the total IgE level.
Furthermore, the top 10 quantile IgE PRS group had a potentially higher
risk for asthma, which was replicated in the Japanese population as
well. Conclusions Our study provided a more comprehensive
understanding of the impact of genomic variants including complex HLA
alleles on serum IgE.

This article investigates the effects of bone marrow-derived mesenchymal
stem cells (BM-MSCs) and dental pulp-derived mesenchymal stem cells
(DP-MSCs) on motor functional recovery and morphological parameters of
the sciatic nerve in rats with crushing injuries. The results showed
that the BM-MSCs, DP-MSCs, and BM +DP-MSCs groups exhibited increased
SFI values compared to the sham group, indicating improved motor
function. Histomorphological analysis revealed preserved perineurium
structure and fascicular organization in all groups, with minimal
irregularities in the sham and BM-MSCs groups. Vascular density was
normal in all groups, and edema and inflammatory cell density were
reduced in the BM +DP-MSCs group. Immunohistochemical staining showed
S100 expression in all treated groups. The study concludes that BM-MSCs,
DP-MSCs, and their combination can effectively promote motor functional
recovery and morphological improvements.

Este artigo teve o objetivo de analisar se existe correlação entre os indicadores operacionais de qualidade da Agência Nacional de Energia Elétrica (ANEEL), e os indicadores financeiros de 4 distribuidoras de energia presente na Bolsa de Valores do Brasil [B]³, compreendendo o período de 2018 a 2021. Os resultados revelaram que os indicadores operacionais de qualidade poderiam estar correlacionados com o desempenho financeiros das distribuidoras de energia, mas, é essencial maior envolvimento entre ambos os indicadores para encontrar evidências de que um indicador afeta o outro.  Logo, a contribuição dessa pesquisa é possibilitar uma visão sobre o setor e verificar a conexão dos indicadores, motivando uma possível otimização do processo de fiscalização e definição dos indicadores de qualidade.
INFLUENCE OF THE PROBABILISTIC METHOD TO SUMMARIZE LOADS ON THE RELIABILITY AND MATERIAL CONSUMPTION OF BUILDING STRUCTURES

Introduction. Load rates are one of the main factors affecting the assessment of the reliability of building structures. All loads are probabilistic in nature, but short-term loads are the most representative in terms of this study since they have the most stochastic nature compared to other types of loads. According to regulatory documents, the short-term loads on a building should be summarized based on their base return period — 50 years. Due to variety of design situations, it is impossible to optimally standardize calculation methods for all types of buildings, therefore, the return period of 50 years is taken for all types of buildings regardless of their required useful life, which in some cases may lead to an excessive safety margin. Methods. To summarize loads on the structural schemes of buildings, two methods are used: deterministic, which is based only on data from regulatory documents, and probabilistic, which takes into account the probabilistic nature of the origin of loads. Reliability is assessed by the limit state method and Rzhanitsyn method. Results. In a number of cases, the use of the probabilistic method when summarizing loads makes it possible to reduce the stiffness properties of sections by equating the period of return of probabilistic loads to the required useful life of the building. Thus, reliability is guaranteed not for 50 years (as in the deterministic method) but for the useful life of a building, and, as a result, the reliability of building structures is not reduced during the entire set period of their operation. This method made it possible to reduce the total weight of the frame of an industrial building by 3 %, and that of a small-sized building — by 27 %, which indicates a more rational application of the proposed method to small-sized building schemes, since in large schemes the gains from the reduced material consumption in structures will be neutralized by the consequences of their failure and the cost of equipment inside the building.

Introduction. The shear strength of concrete, while not being an independently standardized indicator of concrete quality, plays an important role in the analysis of reinforced concrete structures. The concepts related to the dependence of the shear strength of concrete on the standardized compressive and axial tensile strength are quite ambiguous. Self-compacting concrete (SCC), which has been widely used recently, is somewhat different from ordinary concrete (OC) compacted by vibration in terms of structure and properties, and data on the shear strength of SCC are sparse. Purpose of the study: We aimed to clarify the dependence of the shear strength of concrete on the standardized compressive and axial tensile strength, and assess the shear strength of SCC in comparison with that of OC. Methods: We compared the shear strength of SCC with that of OC experimentally, by applying the common methodology with the use of a Mörsch specimen and performing modeling in MATLAB with the use of six strength theories. Results: No significant differences were found in the dependence of the shear strength of SCC in comparison with that of OC at the design age of 28 days. In terms of quantity, the excess of the shear strength of SCC relative to OC is less than 12%. The best agreement with the experimental data among those analyzed is provided by the Geniev theory. The shear strength of concretes is most likely described by the equation Rsh=k*(R*Rt)^(1/2) at k = 0.5–0.6.

Arabic is one of the subjects studied at the State Aliyah Madrasah. However, Arabic is only taught in a limited number of hours, as a result, problems arise in learning Arabic where students find it difficult to understand learning Arabic. So, it is necessary to do a study to identify these problems. This research aims to identify the problems of learning Arabic in the Three Cities of Padang Madrasah Aliyah Negeri (MAN) of West Sumatra. This study used a qualitative method with the type of case study, data sources were taken from ten informants through direct interviews using a set of interview protocols. All data were analyzed thematically using NVivo 12 software. The research findings found six themes regarding students' problems in learning Arabic. The six themes are i) differences in educational background, ii) low vocabulary mastery, iii) lack of teacher initiative to develop an Arabic-language environment, iv) lack of language labs, v) less varied learning methods, and vi) unsupportive environment. The results of this study can be used as initial data for future researchers in studying this problem in different contexts.
