Authors: Cho Heeyoun , Amarasinghe Ananda , Takashima Yoshihiro
Published: January 2024

Problem: Novel vaccines were developed in an unprecedentedly short time in response to the global coronavirus disease (COVID-19) pandemic, which triggered concerns about the safety profiles of the new vaccines. This paper describes the actions and outcomes of three major adverse events of special interest (AESIs) reported in the World Health Organization’s (WHO’s) Western Pacific Region: anaphylaxis, thrombosis with thrombocytopenia syndrome (TTS) and post-vaccination death. Context: During the large-scale introduction of various novel COVID-19 vaccines, robust monitoring of and response to COVID-19 vaccine safety events were critical. Action: We developed and disseminated information sheets about anaphylaxis and TTS; provided tailor-made training for anaphylaxis monitoring and response, webinars about TTS and AESIs, and an algorithm to support decision-making about AESIs following immunization; as well as provided country-specific technical support for causality assessments, including for possible vaccination-related deaths. Outcome: Each major vaccine event and situation of high concern was responded to appropriately and in a timely manner with comprehensive technical support from WHO. Our support activities have not only strengthened countries’ capacities for vaccine safety surveillance and response, but also enabled countries to decrease the negative impact of these events on their immunization programmes and maintain the confidence of health-care professionals and the general population through proactive delivery of risk communications. Discussion: This paper summarizes selected, major AESIs following COVID-19 vaccination and responses made by WHO’s Regional Office for the Western Pacific to support countries. The examples of responses to vaccine safety events during the pandemic and unprecedented mass vaccination campaigns could be useful for countries to adopt, where applicable, to enhance their preparation for activities related to monitoring vaccine safety.

Authors: Mansour Jad , Nassar Joseph E , Estephan Michel , Boulos Karl , Daher Mohammad
Published: January 2024

Acromioclavicular (AC) joint dislocations frequently co-occur with intra-articular glenohumeral pathologies. Few comprehensive studies have focused on labral tears specifically associated with AC joint trauma. This systematic review will address this gap. A comprehensive electronic search was conducted across PubMed, Cochrane Library, and Google Scholar (pages 1–20) spanning from 1976 to May 19, 2023. Seven studies met the inclusion criteria for this systematic review, consisting of three retrospective studies and four case series. These studies collectively involved 1,044 patients, of whom 282 had concomitant labral lesions. The pooled prevalence of intra-articular labral injuries associated with acute AC joint dislocation was 27%. The prevalence of these labral lesions varied significantly between studies, ranging from 13.9% to 84.0% of patients, depending on the study and the grade of AC joint dislocation. Various types of labral tears were reported, with superior labrum anterior to posterior (SLAP) lesions being the most common. The prevalence of SLAP lesions ranged from 7.2% to 77.4%, with higher grades of AC joint dislocations often associated with a higher prevalence of SLAP tears. Moreover, grade V dislocations exhibited a complete correlation with SLAP tears. The studies yielded contradictory findings regarding older age and higher grades of AC joint dislocation as risk factors for concurrent labral lesions. This review underscores the frequent association between labral lesions and AC joint dislocations, particularly in cases of lower-grade injuries. Notably, SLAP lesions emerged as the predominant type of labral tear.

Published: January 2024

Introdução: Idosos com alta longevidade (>80 years) possuem particularidades, enfrentando riscos distintos da população em geral. A depressão maior é preocupante nesse grupo, desencadeando perda funcional e impactando a qualidade de vida. Portanto, compreender os fatores de risco específicos relacionados à depressão maior em octogenários e nonagenários é essencial para mitigar o seu impacto. Métodos: Avaliamos 710 pacientes com 80 anos ou mais do estudo PROCAD, preenchendo a Escala de Depressão Geriátrica. Utilizamos análises de regressão logística/stepwise para identificar preditores relevantes de depressão. Resultados: Identificamos 194 (27,3%) idosos com depressão, sem diferenças significativas em idade, renda e escolaridade. Nas comorbidades, não observamos variações relevantes. Os principais preditores foram sexo feminino (OR=2,44), uso de ≥4 medicamentos (OR=3,07) e suporte social percebido (OR=0,91). Conclusão: Há uma ligação entre depressão em idosos longevos e sexo feminino, polifarmácia e apoio social. Políticas de saúde para mitigar o risco de depressão maior devem priorizar intervenções que melhorem o suporte social e previnam doenças crônicas que levam à polifarmácia nessa população.

Authors: Da Cunha Aldeci Fernandes , Mendes Victor Rafael do Nascimento , Dias Eliane Maria
Published: January 2024

Neste estudo, apresentamos uma discussão teórica e epistemológica acerca da construção da escrita em língua portuguesa como segunda língua para os estudantes surdos. A pesquisa ocorreu por meio de reflexões teóricas, tendo como objetivo dialogar no campo teórico, metodológico e epistemológico em relação ao desenvolvimento do português escrito como segunda linga (L2) para estudantes surdos. Para a análise, vinculamo-nos aos estudos desenvolvidos por Halliday (1994), no campo da linguística sistêmico-funcional; González Rey (1997), com a contribuição da teoria da subjetividade, sobre os sentidos subjetivos que influenciam na aprendizagem; Guarinello (2007), Ribeiro; Silva (2015), Caricari; Muniz (2022), Andrade; Perin (2020), que discutem acerca do trabalho pedagógico para o ensino e a aprendizagem do português escrito como L2. Identificamos que o trabalho pedagógico (ensino e a aprendizagem) com o português escrito, voltado para o estudante com surdez, não pode ocorrer de forma desarticulada do ensino e da aprendizagem da Libras, e que, ao mesmo tempo, não deve ser um ensino baseado em regras e padrões gramaticais previamente estabelecidos, mas de uma prática que valorize os contextos de usos dos falantes. Além disso, o estudo revela a necessidade pensar e de redimensionar o ensino do português escrito para o estudante, de modo que este seja feito a partir do ensino da Libras e das experiências individuais, sociais, culturais e históricas de cada um dos estudantes surdos.

Authors: Chen Tianzhu , Wang Xu , Yuan Yake
Published: January 2024

This study presents a comprehensive methodology for the three-dimensional visualization of electron clouds in Landau energy levels using Monte Carlo simulation techniques. Initially, this research deduces the wave function of electrons in Landau energy levels from the Schrödinger equation, solving it to obtain the eigenvalue equation for a one-dimensional harmonic oscillator containing Hermite polynomials, and then utilizes Mathematica for computational execution, resulting in the generation of intricate three-dimensional visual representations of electron clouds within these Landau levels. By integrating this approach into quantum mechanics education and research, we surpass the constraints inherent in traditional educational resources. This facilitates a visual insight, allowing students to gain a more tangible understanding of electron spatial behavior and a profound comprehension of the electron cloud's genuine physical significance. Concurrently, this study presents a comprehensive technique for rendering the three-dimensional representation of the electron cloud for generic atomic systems, employing the Monte Carlo simulation method and computational programming.

Authors: Xu Haotian , Xing Jiezheng , Gao Yongyong
Published: January 2024

The multi-beam bathymetric system enables the simultaneous collection of multiple seabed depth values within a swath, facilitating a transition from point measurements to line and area measurements. In this study, this article selected a sloped maritime area as our survey target and proposed a hybrid survey line model that incorporates both east-west and north-south orientations. The goal was to design an optimal survey line layout with the shortest total length. To achieve this, this article established a mathematical model for a nonlinear programming problem by considering geometric relationships and aggregating overlap widths, with the objective of minimizing the total length of survey lines. Employing nonlinear regression methods, in this article, the optimal number of survey lines and their respective lengths were determined to meet coverage requirements, and optimal survey line planning was conducted. This article successfully addressed the challenge of optimal path planning for vessels conducting explorations in unknown maritime areas, ultimately concluding that the hybrid model required shorter total survey line lengths. Through analysis, this article discovered that substituting the last survey line with north-south-oriented lines yielded a superior solution, significantly enhancing vessel detection efficiency.

In addition, the limitations as well as the prospects for the devices are discussed accordingly. Overall, these results shed light on guiding further exploration of artificial heart valve development.
Classical model of two electrons interacting in a saddle-shaped electric potential, and a constant perpendicular magnetic field
Authors: Bhargav Ruhaan
Published: January 2024

Electron collisions are fundamental phenomena in modern physics with diverse applications ranging from collision ionization to quantum computing and high-energy plasma studies. This paper focuses on the intricate dynamics of electron collisions within a saddle-shaped electric potential and a constant magnetic field, mimicking the conditions found in beam splitters (and particle accelerators). While existing studies often employ a quantum framework to model these interactions and actually perform the experiment, we adopt a classical approach to provide a more intuitive understanding of the phenomena involved. The transition from quantum to classical representation eliminates probabilistic elements, allowing for precise and deterministic simulations. We utilized a self-programmed python script based on mathematical expressions for the situation, which are also self-derived in the paper. We have managed to replicate 2/4 results simply by altering the starting positions of the electrons and have added further functionality within the python simulations for further research and development i.e., a softening factor controlling the relative screening effect of the material of the constriction, and a time delay feature to be able to offset the starting time of one of the particles relative to the other. Our hope with this paper is for people to be able to take our results, and the model used to derive them, and use it for the purposes of further research and exploration.

This study explores how shallow water conditions influence the behavior of floods and tsunamis through recent advancements, numerical modeling, and observational techniques. The framework of the study involves an examination of the fundamental concept of shallow water, its characteristics, and its influence on wave behavior, sediment transport, and coastal interactions. The study subsequently analyzes the interplay between shallow water and floods, emphasizing the rapid increase in water levels as floodwaters approach shallower areas, contributing to coastal inundation. Similarly, the investigation explores how shallow water dynamics amplify tsunami wave heights and impact, particularly in coastal settings with complex features. By employing advanced simulations and real-world data, the study substantiates the crucial role of shallow water in shaping flood and tsunami risks. While acknowledging limitations, the research concludes by underscoring the implications of these relationships for disaster preparedness, environmental protection, and community resilience. The study contributes to a comprehensive understanding of the profound effects of shallow water dynamics on catastrophic events and highlights the importance of factoring these dynamics into effective disaster management strategies.

Operational amplifiers in integrated circuits come in many varieties and numbers and are an essential part of electronic systems. Its performance directly affects the accuracy and effectiveness of the whole system. As the market demand for operational amplifiers in different fields is growing day by day, according to different kinds of demand, people have designed a variety of operational amplifier structure. This paper describes the basic characteristics of operational amplifiers and analyzes three basic structures that are extremely relevant for modification circuits. The common-source, common-gate circuit structure op-amp has the advantages of high gain, high input common-mode range, high output swing, and high overall gain bandwidth, so it has been adopted as the most commonly used architecture today and in the future. The current improvements in operational amplifier design are mainly focused on two-stage operational amplifiers, and less on multi-stage operational amplifiers. The folded common source and common gate operational amplifier circuits are characterized by good frequency characteristics, comparatively low power consumption and high bandwidth per unit gain. The demands on the performance of operational amplifiers will become higher and more varied, and more excellent improved circuits are needed.

In the educational field, although machine which attempts to learn AI is still in their early stages, the approach has yet to show remarkable results when facing complex challenges without obvious cut-off points, such as grading students’ papers or exploring enormous and complicated data collections. AI can also be used to create virtual learning environments, intelligent testing systems, and automated grading systems. AI in educational fields refers to the application of AI technology to enhance and support the studying processes, such as tracking students’ behavior and constructing models that can accurately hypothesize students’ achievements. It can include the use of AI-powered tutoring systems, personalized learning platforms, and data analysis tools that can help teachers and administrators better understand student needs and progress. This paper mainly concentrates on the field of artificial intelligence tutoring and summarizes the methods by which intelligent tutors assess student performance by comparing some student models and the input, output, and model forms of methods for evaluating fine-grained interactions of intelligent tutors. This article also provides basic information and new perspectives for studying which methods to use to model and evaluate tutorial learning.

Türkiye, Türkistan mücadelesinin önde gelen isimlerinin göç etmesiyle beraber hariçteki Türkler için önemli bir merkez haline gelmiştir. Göçmen Türk liderler kısa zamanda siyasi faaliyetlere girişmiş ve birtakım teşkilatlar kurmaya başlamışlardır. Türkistan Milli Birliği gizli bir teşkilat olduğundan kamuoyuna karşı açık faaliyet gösterebilecek yeni bir kuruluşa ihtiyaç duyulmuştur. Bu ihtiyaç doğrultusunda 1927 yılında Türkistan Türk Gençler Birliği kurulmuştur. Böylece Türkistan Milli Birliği’nin açık faaliyet gösteremediği bütün siyasal ve sosyal faaliyetler bu teşkilat üzerinden yapılmaya başlanmıştır. İstanbul’daki Türkistanlıların bu isimde bir teşkilat kurdukları Yeni Türkistan dergisi vasıtasıyla öğrenilmiştir. TTGB, kanuna uygun şekilde tüm yerel kültür teşkilatlarıyla ilmi ve sosyal münasebet tesis etmek istemiştir. Diğer taraftan birliğin kesinlikle siyasetle uğraşmayacağı açıklanmıştır. Türkistan’ın istiklali doğrultusunda çalışmalar yapan teşkilat, muhacir Türklerin her türden maddi ve manevi sıkıntılarına çözüm üretmeye çalışmıştır. TTGB toplumsal hareketin canlanması, Türkistan milli ruhunun yerleşmesi ve bu ruh doğrultusunda milli kadroların yetişmesi noktasında çok büyük hizmetler vermiştir. Birliğin çok sayıda göçmen Türkistanlının yaşamını şekillendirdiği ve Türkiye’nin ilim hayatının gelişimine değerli bir katkı sağladığı çok açıktır. Birliğin faaliyetleri Türkiye Cumhuriyeti Hükümeti tarafından her zaman desteklenmiş ve dikkatli şekilde takip edilmiştir. Literatürde Türkistan Türk Gençler Birliği ve faaliyetlerini başlı başına ele alan bir çalışma bulunmadığından çalışmamızda bu hususa ilişkin özgün bir katkı yapmak amaçlanmıştır.
