Authors: Bardach Shoshana H , Perry Amanda N , Eccles Elizabeth , Carpenter-Song Elizabeth A , Fowler Ryan , Miers Erin M , Ovalle Anais , de Gijsel David
Published: September 2023

Background

People who inject drugs are experiencing syndemic conditions with increasing risk of infection with hepatitis C (HCV) and HIV. However, rates of accessing HCV and HIV testing and treatment among people who inject drugs are low for various reasons, including the criminalization of drug use, which leads to a focus on treating drug use rather than caring for drug users. For many people who inject drugs, health care becomes a form of structural violence, resulting in traumatic experiences, fear of police violence, unmet needs, and avoidance of medical care. There is a clear need for novel approaches to health care delivery for people who inject drugs.

Objective

This study aimed to analyze the process of a multidisciplinary team—encompassing health care professionals, community representatives, researchers, and people with lived experience using drugs—that was formed to develop a deep understanding of the experiences of people who inject drugs and local ecosystem opportunities and constraints to inform the cocreation of low-barrier, innovative HCV or HIV care in a rural community. Given the need for innovative approaches to redesigning health care, we sought to identify challenges and tensions encountered in this process and strategies for overcoming these challenges.

Methods

Analysis was based on an in-depth review of meeting notes from the project year, followed by member-checking with the project team to revise and expand upon the challenges encountered and strategies identified to navigate these challenges.

Results

Challenges and tensions included: scoping the project, setting the pace and urgency of the work, adapting to web-based work, navigating ethics and practice of payment, defining success, and situating the project for sustainability. Strategies to navigate these challenges included: dedicated effort to building personal and meaningful connections, fostering mutual respect, identifying common ground to make shared decisions, and redefining successes.

Conclusions

While cocreated care presents challenges, the resulting program is strengthened by challenging assumptions and carefully considering various perspectives to think creatively and productively about solutions.

Authors: Zhang Zeyu , Fang Meng , Wu Rebecca , Zong Hui , Huang Honglian , Tong Yuantao , Xie Yujia , Cheng Shiyang , Wei Ziyi , Crabbe M James C , Zhang Xiaoyan , Wang Ying
Published: September 2023

BACKGROUND

Biomedical relation extraction (RE) is of great importance for researchers to conduct systematic biomedical studies. It not only helps knowledge mining, such as knowledge graphs and novel knowledge discovery, but also promotes translational applications, such as clinical diagnosis, decision-making, and precision medicine. However, the relations between biomedical entities are complex and diverse, and comprehensive biomedical RE is not yet well established.

OBJECTIVE

We aimed to investigate and improve large-scale RE with diverse relation types and conduct usability studies with application scenarios to optimize biomedical text mining.

METHODS

Data sets containing 125 relation types with different entity semantic levels were constructed to evaluate the impact of entity semantic information on RE, and performance analysis was conducted on different model architectures and domain models. This study also proposed a continued pretraining strategy and integrated models with scripts into a tool. Furthermore, this study applied RE to the COVID-19 corpus with article topics and application scenarios of clinical interest to assess and demonstrate its biological interpretability and usability.

RESULTS

The performance analysis revealed that RE achieves the best performance when the detailed semantic type is provided. For a single model, PubMedBERT with continued pretraining performed the best, with an F1-score of 0.8998. Usability studies on COVID-19 demonstrated the interpretability and usability of RE, and a relation graph database was constructed, which was used to reveal existing and novel drug paths with edge explanations. The models (including pretrained and fine-tuned models), integrated tool (Docker), and generated data (including the COVID-19 relation graph database and drug paths) have been made publicly available to the biomedical text mining community and clinical researchers.

CONCLUSIONS

This study provided a comprehensive analysis of RE with diverse relation types. Optimized RE models and tools for diverse relation types were developed, which can be widely used in biomedical text mining. Our usability studies provided a proof-of-concept demonstration of how large-scale RE can be leveraged to facilitate novel research.
Health Care and Social Work Students’ Experiences With a Virtual Reality Simulation Learning Activity: Qualitative Study (Preprint)
Authors: Helle Nikolina , Vikman Miriam Dubland , Dahl-Michelsen Tone , Lie Silje Stangeland
Published: September 2023

BACKGROUND

Virtual reality is used to an increasing extent in various fields and is now making inroads into health and social education. Virtual reality simulation can provide a safe and controlled environment for students to practice and master skills that are transferable to real-world situations without putting patients, clients, or themselves at risk of any harm. Virtual reality simulation using 360° videos represents a novel approach to simulation in health care and social work education, and this inspired our interest in exploring students’ experiences with such a learning activity.

OBJECTIVE

The aim of this study was to explore occupational therapy, social education, nursing, and social work students’ experiences with virtual reality simulation as a learning activity in an interdisciplinary subject.

METHODS

The data were collected through 6 semistructured focus groups with 28 students. We conducted the focus groups after the students from the 4 education programs had participated in the virtual reality simulation at 3 campuses at a specialized university in Norway. Each focus group interview was facilitated by 1 moderator and 1 facilitator, a combination of experienced researchers and novices. We followed a qualitative design using the 6-step thematic analysis described by Braun and Clarke.

RESULTS

The analysis revealed 3 overall themes for students’ experiences with the virtual reality simulation. The first theme, 360° videos provide observations for individual learning, illustrates how learning can take place through the students’ experiences with sensory inputs and observations from the 360° videos. Students experienced that the video enabled them to individually reflect and achieve learning from what was considered a clinically relevant video. The second theme, 360° videos activate emotional learning, demonstrates how the students experienced emotional engagement when watching the 360° videos. The degree of realism provided in the video was considered as important for the students’ learning. The last theme, Debrief sessions enhance comprehensive learning, pinpoints how the students experienced learning through reflective discussions with other students after watching the 360° videos. Students claimed this process to be a vital part of the learning activity.

CONCLUSIONS

Virtual reality simulation represents a promising learning activity to enhance the professional learning of health care and social work students. It offers opportunities for individualized learning through observations, and it also engages students emotionally in the learning process. The combination of 360° videos and group discussions in virtual reality appears promising to enhance professional learning outcomes and competence, which may contribute to improved health care and social work services.

BACKGROUND

With the increasing application of Large Language Models (LLMs) like ChatGPT in various industries, its potential in the medical domain, especially in standardized examinations, has become a focal point of research.

OBJECTIVE

To assess the clinical performance of ChatGPT, focusing on its accuracy and reliability in the Chinese National Medical Licensing Examination (CNMLE).

METHODS

The CNMLE 2022 question set, consisting of 500 single-answer multiple choices questions, were reclassified into 15 medical sub-specialties. Each question was tested 8 to 12 times in Chinese on the OpenAI platform from April 24 to May 15, 2023. Three key factors were considered: the version of GPT-3.5 and 4.0, the prompts designation of system roles tailored to medical sub-specialties, and repetition for coherence. A passing accuracy threshold was established as 60%. The χ2 tests and Kappa values were employed to evaluate the model's accuracy and consistency.

RESULTS

GPT-4.0 achieved passing accuracy of (71.0% - 74.7%), significantly higher than that of GPT-3.5 (50.3% - 54.8%, P < 0.001). Both models showed relatively high coherence between initial and 2nd response, with Kappa values of 0.778 and 0.610. System roles boosted accuracy for both GPT-4.0 (0.3% - 3.7%) and GPT-3.5 (1.3% - 4.5%), and increased the Kappa by 0.023 and 0.035 respectively. In multi-specialty analysis, GPT-4.0 passed the threshold in 14 of 15 sub-specialties, while GPT-3.5 did so in 7 of 15 on the first response.

CONCLUSIONS

GPT-4.0 passed the CNMLE and outperformed GPT-3.5 in key areas such as accuracy, consistency, and medical sub-specialty expertise. Adding a system role enhanced the model's reliability and answer coherence. GPT-4.0 showed promising potential in medical education and clinical practice, meriting further study.

Integrating Cultural-Historical Activity Theory and Authentic Learning with Technology in Teaching and Learning: A Case Study Analysis
Authors: Hamaluba Tommie , Hamaluba Moono
Published: September 2023

This research work presents a comprehensive framework that merges Cultural-Historical Activity Theory (C), Authentic Learning (A), and six distinct roles of Technology (T) in the context of teaching and learning. The study reviews five individual case studies that explore the utilization of technology in educational settings, examining their alignment with the CAT framework. The research highlights the significance of adventure games as an effective medium for knowledge construction, wherein embedded puzzles and core content serve as extrinsic mediators, while discussions between players intrinsically mediate knowledge construction. Additionally, artifacts of mass media, such as games, software, and other media, facilitate knowledge production when they function as tools rather than objects of the activity. Drawing on Vygotskian concepts of social tool-mediated dialogical knowledge construction, the research concludes that games and media play an integral role in enhancing teaching and learning experiences. This study aims to contribute to the broader understanding of technology integration in education, encouraging educators to adopt transformative approaches to optimize the benefits of technology in the learning process.
Contact Linguistics of Interlanguage
Authors: Wei Longxing
Published: September 2023

Different from traditional definitions of “interlanguage” and descriptions of interlanguage production, this study defines interlanguage in terms of its outstanding linguistic characteristics at the level of abstract lexical structure, including its three sublevels: lexical-conceptual structure, predicate-argument structure, and surface morphological realization patterns (Myers-Scotton and Jake 1995). Also different from most previous studies of interlanguage, this study views interlanguage or any interlanguage system as an outcome of a language-contact phenomenon. Adopting the Matrix Language Frame model (Myers-Scotton 1993[1997]) of bilingual intrasentential codeswitching in particular and contact linguistics in general, this study identifies the “matrix language” or the grammatical frame which structures interlanguage and reviews such a matrix language as a composite (Jake 1998; Wei 2009c). By adopting the Bilingual Lemma Activation model (Wei 2002, 2015, 2020), this study explores the nature and activity of the bilingual mental lexicon during interlanguage development. Accordingly, it proposes a particular approach to the nature and sources of second language learner errors or first language transfer in second language learning. It concludes that any interlanguage system must be driven by an incompletely acquired target language system in general and by an incompletely acquired target language abstract lexical structure in particular.

Authors: Fuentes Alcalá Mario Luis , Arellano Almanza Saúl
Published: September 2023

México es un país en el que existen condiciones generalizadas de incumplimiento de los derechos de las niñas, niños y adolescentes. Con base en la información oficial disponible, puede sostenerse que no existe un solo ámbito de derechos en el que el país haya tenido un buen desempeño. Lo más preocupante de esta situación, exponen los autores, se encuentra en que se trata de una cuestión histórica, estructural y sistémica. Los hallazgos que se tienen en la investigación que da origen a este texto, se muestra cómo, al menos desde el 2008, cuando se llevó a cabo la primera medición multidimensional de la pobreza y hasta el año 2020, de forma constante, 50% o más de la población menor de 18 años en el país ha sido identificada en esa condición. En este nuevo cálculo del Índice de los derechos de la niñez mexicana, se construye una estimación que permite mostrar el estancamiento que se registra en todas las dimensiones para las que existe información desagregada a nivel estatal, construyendo un comparativo para los últimos cinco años completos para los que se dispone de datos: 2016-2020. Este Índice muestra claramente las dramáticas condiciones en que vivía la niñez mexicana, justo al inicio de la pandemia de la COVID19 y del confinamiento obligado; por lo que en posteriores mediciones, podrá compararse con toda precisión cuál fue el impacto que tuvo la pandemia en el grado de cumplimiento de sus derechos.

Authors: Tripathi Anurag , Kumari Uma
Published: September 2023

Abstract: Kidney cancer, particularly renal cell carcinoma (RCC), is a significant global health concern characterized by its high morbidity and mortality rates. In this study, we employ a multifaceted approach to gain insights into the molecular mechanisms underlying kidney cancer and to identify potential drug targets for therapeutic intervention. To achieve this, we conducted a comprehensive comparative analysis of gene expression profiles in normal and cancerous kidney tissues, utilizing tools such as BLAST and gene analysis from the COSMIC database. This analysis allowed us to identify key genetic alterations and pathways associated with kidney cancer progression. Furthermore, molecular docking simulations were performed to predict potential drug candidates that could target specific proteins implicated in kidney cancer development. The aim was to prioritize molecules with high binding affinity and therapeutic potential. Additionally, cobalt analysis was utilized to investigate the metalloprotein content within kidney cancer cells, shedding light on potential metalloprotein targets for drug development.The results of this study provide valuable insights into the molecular basis of kidney cancer, offering a foundation for the identification of novel drug targets and the development of targeted therapies for this life-threatening disease. These findings contribute to our understanding of kidney cancer pathogenesis and may ultimately improve patient outcomes and the overall management of this challenging malignancy.

Published: September 2023

Currently, precision gardening necessitates the use of robotic universal platforms featuring modular multi-fan sprayers, typically equipped with 4-6 fans. As new technologies emerge, the demands placed on spraying ventilation systems are also evolving. (Research purpose) The objective of this research is to establish the design and technological speciﬁcations of the multi-fan sprayer module. (Materials and methods) The research is grounded on fundamental equations of energy and mass conservation in the ﬁeld of applied gas dynamics, speciﬁcally the Bernoulli equation and the ﬂow continuity equation. To analyze the pressure distribution within the fan duct and calculate the gas jet, a speciﬁc methodology was employed in this research. Additionally, the research utilizes analytical expressions and industry standards to determine universal parameters and dimensions of fans and liquid atomizers. (Results and discussion) Theoretical calculations were performed to determine the main parameters. The results are as follows: the air consumption required to cover a given crown volume is 11.28 cubic meters per second; the air consumption by one fan is 1.88 cubic meters per second; the air ﬂow rate at the fan outlet reaches 17.9 meters per second; pressure generated by the fan is 192.25 pascals; power required to drive one fan is 0.170 kilowatts; the installed power of the fan motor is 0.204 kilowatts; the jet initial section length is 1.53 meters; the axial jet velocity is 13.6 meters per second; the air consumption is 12.84 cubic meters per second; the round jet diameter is 1.58 meters. (Conclusions) The technological scheme of a multi-fan sprayer has been developed and justiﬁed. Calculation equations have been proposed to determine the distribution of static, dynamic, and total pressure in diﬀerent sections of the sprayer fan.  An algorithm for calculating the parameters of the sprayer module has been presented. The numerical values of the parameters for the multi-fan sprayer module have been determined for speciﬁc operating conditions.

Authors: Abdulmazhidov K. A. , Balabanov B. I. , Karpov M. V.
Published: September 2023

The paper substantiates the necessity of developing new replaceable working bodies for the OKN-0.5 reclamation canal cleaner. The study emphasizes the signiﬁcance and application features of bucket working bodies, considering the prevalent conditions of reclamation drainage canals, which often contain sediment, silting, and various types of vegetation. (Research purpose) The research objective is to investigate the process of cleaning the channel bottom and slopes using the proposed replaceable bucket. (Materials and methods) The paper proposes an enhanced design of a replaceable bucket with an additional gripper. (Results and discussion) The paper outlines the calculations conducted to determine the appropriate bucket width, dimensions of the additional gripper, the forces involved in clearing sediments and silting, and the machine's working capacity. A comprehensive three-dimensional model of the proposed working body with the additional gripper was created using Inventor Pro graphics package. Additionally, the bucket's structural strength was evaluated through ﬁnite element method calculations.  The canal cleaner’s stability was assessed with the inclusion of a separate hydraulic drive for the additional gripper, utilizing a mini-program generated in the Mathcad system. (Conclusions) The conclusions drawn from the study recommend a bucket width of 2000 millimeters and the development of an additional gripper with a hydraulic drive. The proposed design proves essential for securing sediments, grassy, and shrubby vegetation in the bucket until they can be eﬃciently unloaded onto the berm. Based on technical and operational data, the canal cleaner belongs to machines of positional periodic action, with a working capacity of 180-330 meters per hour. The research also identiﬁes criteria for achieving high-quality cleaning of reclamation drainage canals up to 2.5 meters deep.

Authors: Kornyushin Yu. P. , Lavrov A. V. , Sidorova A. V.
Published: September 2023

The research article demonstrates that agricultural transport and technological systems are susceptible to external random inﬂuences during their operation. By accurately describing and modeling these eﬀects, the performance of the tool can be enhanced during the research and design stages. (Research purpose) The objective of this research is to generate random processes with predeﬁned correlation functions that simulate the proﬁle of the supporting surface under the wheels of agricultural transport and technological systems during operations. Additionally, the study aims to visually represent the resulting random implementations of the support surface proﬁle height. (Materials and methods) The proposed approach considers the variation in support surface proﬁle height along the trajectory of agricultural transport and technological systems, while maintaining a constant speed, as a stationary random process. The selection of the correlation function type and its parameters is dependent on the speciﬁc characteristics of the support surface. Subsequently, using the Matlab environment, the model for the support surface proﬁle height under the wheels is developed. (Results and discussion) Successful implementations of support surface proﬁle height have been achieved for two distinct scenarios: asphalt and wheat stubble. A comparative analysis is conducted between the correlation function of the simulated implementation of the random process and the original correlation function. (Conclusions) The proposed algorithm has demonstrated its capability to generate a random process with speciﬁed correlation function properties, accurately describing the height ﬂuctuations of the support surface proﬁle under the wheels of agricultural transport and technological systems. The adequacy of the algorithm has been conﬁrmed through a comprehensive analysis of at least 50 implementations, highlighting its eﬀectiveness and reliability.

Authors: Khamuev V. G. , Gerasimenko S. A.
Published: September 2023

The paper highlights that the study of the soybean seed separation processes in a vertical deep aspirating channel contributes to the improvement of technical and economic indicators in grain cleaning equipment. (Research purpose) The research aims to substantiate the thickness of narrowing partitions in the vertical deep aspirating channel. (Materials and methods) A prototype of a vertical deep aspirating channel with three sections of varying height, was used for cleaning soybean seeds. The optimal thickness of the narrowing partitions in the channel has been justiﬁed. Impurity extraction completeness and seed separation eﬃciency within a vertical aspirating channel were assessed for soybean seed cleaning under maximum speciﬁc grain load conditions. (Results and discussion) The following parameters have been determined: the optimal thickness for the narrowing partitions is 70 millimeters under a maximum speciﬁc grain load of 5 kilograms per square centimeter per hour. Seed losses do not exceed 3 percent in the aspirating channel with narrowing partitions, with impurity extraction completeness of 74 percent for the «Waste» fraction. The eﬃciency of the separation process stands at 71 percent, and the purity level of the «Seeds» fraction reaches 81 percent in a single pass during the preliminary cleaning stage. (Conclusions) It has been established that the use of narrowing partitions in a vertical aspirating channel during soybean seed cleaning leads to an increase in the speciﬁc grain load up to 5 kilograms per square centimeter per hour, compared to 2 kilograms per square centimeter per hour achieved by traditional pneumatic separation channels. The proposed technical solution reduces soybean seed losses to 3 percent (compared to the initial requirements of no more than 10 percent) in a single pass and reduces machine power consumption from 4.5 to 2.25 kilowatt-hours.
PERCEPÇÕES DE ESTUDANTES DE FÍSICA SOBRE TRÊS ESTUDOS DE CASO: UMA ANÁLISE ORIENTADA PELO MODELO DE TOMADA DE DECISÃO DE KORTLAND
Authors: Junior Edmundo Rodrigues , Hygino Machado Cassiana Barreto
Published: September 2023

Os conceitos relacionados ao ensino de ciências muitas vezes são transmitidos de forma descontextualizada da realidade discente, levando-o a memorizar os conteúdos. Buscando melhorar esse cenário aplicamos a estudantes em formação continuada três estudos de caso com potencial sociocientífico. Os casos envolviam um planejamento de uma aula de física, a interferência entre os sinais de televisão e celular e o desenvolvimento de máquina térmica. A análise das percepções dos estudantes em relação aos casos foi orientada pelo modelo de tomada de decisão proposto por Kortland (1996). O modelo mostrou-se eficaz, pois permitiu que os estudantes destacassem aspectos ambientais e sociais tais como: preocupações com problema da emissão de gás carbônico pelas máquinas térmicas; possíveis efeitos biológicos das radiações emitidas pela radiação microonda advinda do celular; substituição do trabalho humano pelas máquinas e a necessidade de um envolvimento da família num planejamento de uma aula de física. Espera-se que este trabalho possa oferecer subsídios aos estudantes de pós-graduação para a criação e aplicação de seus próprios casos em sua prática em sala de aula.
Central and Peripheral Physiological Responses to Decision Making in Hoarding Disorder
Authors: Levy Hannah , Naples Adam , Collett Sarah , McPartland James , Tolin David
Published: September 2023

Individuals with hoarding disorder (HD) have difficulty parting with
personal possessions, which leads to the accumulation of excessive
clutter. According to a proposed biphasic neurobiological model, HD is
characterized by blunted central and peripheral nervous system activity
at rest and during neutral (non-discarding) decisions, and exaggerated
activity during decision-making about discarding personal possessions.
Here, we compared the error-related negativity (ERN) and
psychophysiological responses (skin conductance, heart rate and heart
rate variability, and end tidal CO2) during neutral and
discarding-related decisions in 26 individuals with HD, 37 control
participants with anxiety disorders, and 28 healthy control participants
without psychiatric diagnoses. We also compared alpha asymmetry between
the HD and control groups during a baseline resting phase. Participants
completed a series of Go/No Go decision-making tasks, one involving
choosing certain shapes (neutral task) and the other involving choosing
images of newspapers to imaginally “discard” (discarding task).
Contrary to hypotheses, there were no group differences in the ERN or
any psychophysiological measures. Alpha asymmetry at rest did not differ
between groups. The findings suggest that the ERN and
psychophysiological responses may not differ in individuals with HD
during simulated discarding decisions relative to control participants,
although the null results may be explained by methodological challenges
in using Go/No Go tasks as discarding tasks. Future replication and
extension of these results will be needed using ecologically valid
discarding tasks.
Achieving A Competitive Advantage Supply Chain Management Practices and Responsiveness
Authors: Muhammad Rosliniwati , Saad Shatina
Published: September 2023

Today's business environment is highly competitive and globalized, characterized by shorter product life cycles and demanding customers. As a result, supply chains must be responsive to changes in the marketplace to maintain and create a competitive advantage. While previous studies have acknowledged the advantages of effective supply chain management (SCM) in gaining a competitive edge, there remains a limited understanding of the implications of adopting various SCM practices. To address this gap, this conceptual study focuses on examining the relationship between SCM practices (strategic supplier partnership, customer relationship, information sharing, and postponement) and both supply chain responsiveness and competitive advantage within the Malaysian timber industry. The study integrates the Resources Based View (RBV), Dynamic Capabilities theory, and Natural Resource-Based View (NRBV) theory.

Authors: Sukri Norellani Binti , Mohamad Arshad Afiza Azura , Cheng Chuah Soo , Mohd Aminuddin Zaidi , Arshad Azlin Shafinaz
Published: September 2023

Philanthropy is the desire to promote the well-being of others. It is about looking for and helping the welfare of others, particularly by giving them money for good reasons. Philanthropy is not only confined to the contribution of money, but it involves making efforts for religious purposes and self-satisfaction towards others. The level of charity among Malaysian citizens is alarming in 2015, Malaysia ranked 10th in the World Giving Index but in 2021 the ranking has dropped tremendously to 29th place. This has shown that Malaysians are getting less interested in participating in charitable activities and doing general good deeds. Therefore, there is an urgent need to look broadly at the philanthropic behavior of Malaysians. This research aims to determine the factors influencing philanthropic behavior among youth in Malaysia. For this study, a survey was conducted to the target population which is youth. Data was collected by distributing questionnaires via emails and WhatsApp groups and data was analyzed using SPSS and PLS-SEM. Findings show that religion and altruism are significant to the philanthropic behavior of Malaysian youth. This study has provided valuable insights into youth philanthropy by identifying solutions to further create awareness of philanthropy.

Structural and spectroscopic characterization (SXRD, IR, liq. N2 temperature Raman, UV) of hexaamminecobalt(III) dibromide permanganate, [Co(NH3)6]Br2(MnO4) (compound 1), are described. There is a 3D hydrogen bond network including N?H???O?Mn and N?H???Br interactions, which could serve as potential reaction centres for solid-phase redox reactions between the ammonia ligands and/or bromide ions as reductants and permanganate ions as oxidant agents. The effect of the nature of halogen ions on the structural and spectroscopic properties of [Co(NH3)6]Br2(MnO4) and the analogous chloride compound, [Co(NH3)6]Cl2(MnO4) (compound 2), are discussed in detail.

Apatites, being one of the most numerous mineral-like families of compounds, are considered as a matrix for binding lead ions, which is dangerous for the biosphere. The crystal-chemical (composition, structure) and thermophysical aspects (thermal expansion) are considered as the basis for analysing the properties of this kind of material. It is suggested that substances of the composition Pb5(AIVO4)2(BVIO4), Pb5(AIVO4)(CVO4)2 can be a perspective form of lead binding materials based on compounds with the structure of apatite (AIV = Si, Ge; BVI = S, Cr; CV = P). Such compounds, as it was shown by DTA and HTXRD experiments, are distinguished by the absence of polymerphism and the abnormal ordering of structure. Also, they have relatively low values of thermophysical indicators (the rate of change of linear thermal expansion coefficients is 0.02?0.03?106 K-1; values of the volume thermal expansion coefficients are 40?70?106 K-1). Compounds Pb5(SiO4)(PO4)2 (a = 9.78782(16) ?, c = 7.31084(16) ?, V = 606.555(23) ?3, R-bragg = 4.694 %) and Pb5(GeO4)(PO4)2 (a = 9.87697(12) ?, c = 7.33136(11) ?, V = 619.388(17) ?3, R-bragg = 1.730 %) were obtained, identified and crystallographically characterised for the first time.
Artificial Intelligence and Diabetic Retinopathy: AI Framework, Prospective Studies, Head-to-head Validation, and Cost-effectiveness

Current guidelines recommend that individuals with diabetes receive yearly eye exams for detection of referable diabetic retinopathy (DR), one of the leading causes of new-onset blindness. For addressing the immense screening burden, artificial intelligence (AI) algorithms have been developed to autonomously screen for DR from fundus photography without human input. Over the last 10 years, many AI algorithms have achieved good sensitivity and specificity (>85%) for detection of referable DR compared with human graders; however, many questions still remain. In this narrative review on AI in DR screening, we discuss key concepts in AI algorithm development as a background for understanding the algorithms. We present the AI algorithms that have been prospectively validated against human graders and demonstrate the variability of reference standards and cohort demographics. We review the limited head-to-head validation studies where investigators attempt to directly compare the available algorithms. Next, we discuss the literature regarding cost-effectiveness, equity and bias, and medicolegal considerations, all of which play a role in the implementation of these AI algorithms in clinical practice. Lastly, we highlight ongoing efforts to bridge gaps in AI model data sets to pursue equitable development and delivery.

Anniversary Collection of Research Articles in Honor of Professor Andrei Nikolaev
Authors: Егоров А.Н.
Published: September 2023

Анализируется сборник научных трудов к 60-летию доктора исторических наук, профессора, заведующего кафедрой русской истории (ХIХ–ХХI вв.) РГПУ им. А.И. Герцена А.Б. Николаева. В статьях сборника показан его вклад в изучение роли Государственной думы в Февральской революции и конструировании новой власти. Отмечается научно-организаторская роль А.Б. Николаева, прежде всего в организации ежегодных научных конференций по истории российского парламентаризма «Таврические чтения». Подчеркивается значение рецензируемого сборника с историографической и источниковедческой точки зрения. Показано, что в сборнике, с одной стороны, отражено развитие историографической мысли по одной из важнейших проблем Великой российской революции 1917 г. – роли Государственной думы в революционных событиях, с другой – в целом ряде статей вводятся в научный оборот новые материалы по политической истории России начала ХХ в.

The review analyzes the collection of papers dedicated to the 60th anniversary of Andrei B. Nikolaev, Doctor of Historical Sciences, Professor, Head of the Department of Russian History (19th – 21st Centuries) of Herzen State Pedagogical University of Russia. The articles in the collection highlight A. Nikolaev’s contribution to the study of the State Duma’s role in the February Revolution and in the construction of new authority. Scientific and organizational role of A. Nikolaev, primarily, in the Tauride Readings, an annual scientific conference on the history of Russian parliamentarism, is pointed out. The importance of the collection under review is emphasized from the point of view of historiography and source study. It has been shown that, on the one hand, the collection reflects the development of historiographical thought concerning the role of the State Duma in revolutionary events, one of the most important issues of the Great Russian Revolution of 1917. On the other hand, new materials on political history of Russia in the early 20th century are introduced into scientific circulation in a number of articles of the collection under review.

The “Violet” Spectrum of Russian Emigration
Authors: Иванов А.А.
Published: September 2023

В публикации рассматривается монография П.Н. Базанова, посвященная политической и издательской деятельности «просоветских» организаций русской эмиграции первой волны: сменовеховцев, младороссов, национал-максималистов и других представителей пореволюционного движения, отвергавших идею «активизма» – террористической и вооруженной борьбы с Советской Россией. Анализируются взгляды и деятельность эмигрантских движений, вышедших за пределы дореволюционных партийных рамок и политических концепций, сумевших творчески подойти к осмыслению большевистской революции и новой эпохи в жизни нашей страны. Особое внимание в рецензии уделено возникновению терминов «фиолетовые» и «ультрафиолетовые», проблеме появления лозунга «Царь и Советы», фактам биографии видных деятелей пореволюционного движения.

The review examines the monograph by P. Bazanov devoted to the political and publishing activities of the “pro-Soviet” organizations of Russian emigration of the first wave: the Smenovekhovtsy, the Mladorossi, the National Maximalists, and other representatives of the post-revolutionary movement who rejected the idea of “activism,” i.e. terrorist and armed struggle against Soviet Russia. The analysis focuses on the views and activities of the emigrant movements that went beyond the pre-revolutionary party framework and political concepts and managed to creatively approach the understanding of the Bolshevik revolution and the new era in the life of our country. Special attention in the review is paid to the emergence of the terms “violet” and “ultraviolet,” the problem of the appearance of the slogan “The Tsar and the Soviets,” and biographical facts of the prominent figures of the post-revolutionary movement.
