Authors: Tlili Sabrine , Zoudji Bachir , Ben Mahfoudh Hatem 
Published: February 2025

Abstract

Objectives
Intending to facilitate learning from narrated tactical diagrams, this study investigates how drawing influences the memorization of soccer scenes given individuals’ visuospatial abilities (VSA).

Methods
Fifty-four male university students, all novices in soccer domain were randomly assigned to two groups. First group, without-drawing, viewed a pre-drawn diagram while listening to a concurrent oral explanation. Second group, with-drawing, listened to the same description while observing the coach simultaneously drawing the diagram. All participants conducted a control test to assess their VSA level and completed the main test, which included rating their overall mental effort and recalling/reconstructing the tactical scene.

Results
The principal results indicate an interaction between VSA and drawing: individuals with high-VSA particularly benefited better from the with-drawing condition, while those with low-VSA did not, thereby confirming the ability-as-enhancer hypothesis.

Conclusions
Overall, this study underscores the importance of aligning the choice of drawing formats with individual characteristics, especially VSA, to enhance memorization from narrated tactical diagrams.
Library Leadership in Minority Serving Institutions: Investigating the Backgrounds of MSI Library Directors
Authors: Lund Brady D. 
Published: February 2025

Abstract
This article reports the findings of a study of the educational backgrounds of library directors at Minority-Serving Institutions (MSIs) in the United States. Using a content analysis of MSI library websites and director/dean profiles, the leadership of 746 minority-serving institutions was identified including whether they have earned an American Library Association-accredited Master of Library and Information Science (MLIS) degree and from which library and information science (LIS) program it was earned. The study found that 83.8 % of MSI library directors held a MLIS degree though the percentage can vary dramatically based on MSI type, with only 50 % of Tribal College and University directors possessing this degree compared to 92.6 % of Historically Black College and University library directors. The LIS programs with the greatest number of MSI library director alumni are San Jose State University, the University of North Texas, and the University of Illinois, though the top programs for educating these MSI library directors also varies based on the MSI type. The findings of this study have implications for better understanding MSI libraries and the role of LIS programs in preparing future MSI library directors.

Abstract
This work investigates the quadratic and quartic nonlinear diffusion–reaction equations with nonlinear convective flux terms, which are investigated analytically. Diffusion–reaction equations have a wide range of applications in several scientific areas, such as chemistry, biology, and population dynamics of the species. The new extended direct algebraic method is applied to obtain abundant families of solitary wave solutions. Different types of solitary wave solutions are obtained by applying this analytical method. This approach provides the solutions in the form of single and combined wave structures, which are observed in shock, complex solitary-shock, shock-singular, and periodic-singular forms. Some of the solutions are depicted graphically to illustrate the fact that they are, indeed, wave solutions of the mathematical model.
ПАРАЛЛЕЛЬНЫЙ АЛГОРИТМ ДЛЯ ПОЛУНЕЯВНОГО МЕТОДА ЧАСТИЦ В ЯЧЕЙКАХ С СОХРАНЕНИЕМ ЭНЕРГИИ И ЗАРЯДА
Authors: БЕРЕНДЕЕВ Е.А. , ТИМОФЕЕВ И.В. 
Published: February 2025

Статья посвящена вопросам построения параллельного алгоритма для расчёта динамики плазмы методом частиц в ячейках с использованием полунеявной схемы, сохраняющей энергию и заряд. Данная схема представляет собой двухстадийный предиктор-корректор, где на этапе предсказания используется полунеявный метод Лапенты, в котором сохраняющий энергию линейный ток не удовлетворяет локальному закону Гаусса, а на этапе коррекции токи, электромагнитные поля и скорости частиц подправляются так, чтобы разностные законы сохранения энергии и заряда выполнялись точно. Этот подход оказывается эффективным для моделирования разномасштабных явлений с достаточно большим временным шагом, однако является ресурсоёмким, поскольку требует не только решения двух систем линейных уравнений за шаг, но и перестроения всей матрицы системы. Авторами разработан матрично-операторный алгоритм для программной реализации этой схемы, позволяющий эффективно распараллелить вычисления, а также использовать различные библиотеки для работы с матрицами и решателями систем линейных уравнений. Для построения матрицы использован алгоритм построчного хранения с поиском элементов через хэш-таблицу, что уменьшает объём используемой памяти, число синхронизаций потоков и позволяет существенно ускорить вычисления. Рассматриваемый алгоритм успешно применён в коде Beren3D.
Parallel algorithm for semi-implicit particle-in-cell method with energy and charge conservation The article is devoted to the construction of a parallel algorithm for calculating plasma dynamics by the particle-in-cell method using a semi-implicit scheme that conserves energy and charge. This scheme is a two-stage predictor-corrector, where at the prediction stage the semi-implicit Lapenta method is used, in which the energy-conserving linear current does not satisfy the local Gaussian law, and at the correction stage the currents, electromagnetic fields and particle velocities are corrected so that the difference laws of conservation of energy and charges were carried out accurately. This approach turns out to be effective for modeling multi-scale phenomena with a sufficiently large time step, however, it is resource-intensive, since it requires not only solving two systems of linear equations per step, but also rebuilding the entire matrix of the system. The authors have developed a matrix-operator algorithm for the software implementation of this scheme, which makes it possible to effectively parallelize calculations, as well as use various libraries for working with matrices and solvers for systems of linear equations. To construct the matrix, a row-by-row storage algorithm is used with searching for elements through a hash table, which reduces the amount of memory used, the number of thread synchronizations and can significantly speed up calculations. The algorithm in question has been successfully applied in the Beren3D code.

В данной работе предлагается линейная конечно-разностная схема второго порядка для уравнения Аллена-Кана с общей положительной мобильностью. Для временной дискретизации используется схема Кранка-Николсона (КН) и формула Тейлора, а для пространственной аппроксимации - метод центральных конечных разностей. Обсуждаются дискретный принцип максимума (ПМ), дискретная энергетическая устойчивость и оценка ошибки в L∞-норме. Представлены некоторые численные примеры для проверки теоретических результатов.
In this paper, a linear second-order finite difference scheme is proposed for the Allen-Cahn equation with a general positive mobility. The Crank-Nicolson scheme and Taylor's formula are used for temporal discretization, and the central finite difference method is used for spatial approximation. The discrete maximum bound principle (MBP), the discrete energy stability and L∞-norm error estimation are discussed, respectively. Finally, some numerical examples are presented to verify our theoretical results.

Мы представляем анализ сходимости метода конечных разностей для решения на четырехугольных сетках задач двумерных течений в однородных пористых средах с полным тензором проницаемости. Мы начинаем с вывода дискретной задачи, используя нашу конечно-разностную формулу для смешанной производной второго порядка. Результат существования и единственности решения этой задачи получается благодаря положительной определенности соответствующей матрицы. Исследуются их теоретические свойства, а именно, устойчивость (с соответствующей дискретной энергетической нормой) и оценки ошибки (с L2-нормой, относительной L2-нормой и L∞-нормой). Представлены численные расчеты.
We present in this work a convergence analysis of a Finite Difference method for solving on quadrilateral meshes 2D-flow problems in homogeneous porous media with a full permeability tensor. We start with the derivation of the discrete problem by using our finite difference formula for a mixed derivative of second order. A result of existence and uniqueness of the solution for that problem is given via the positive definiteness of its associated matrix. Their theoretical properties, namely, stability on the one hand (with the associated discrete energy norm) and error estimates (with L2-norm, relative L2-norm and L∞-norm ) are investigated. Numerical simulations are shown.

Published: February 2025

Представлены результаты применения численного метода для решения одномерных гиперболических уравнений. Эти уравнения моделируют динамику жидкости в трубе с меняющимся поперечным сечением. Уравнения записаны в терминах напора и расхода. Для численного моделирования используются радиальные базисные функции и оптимизация методом наименьших квадратов. Этот численный метод предназначен для работы с произвольным распределением узлов в области задачи. Основы применения численного метода были изложены в нашей предыдущей работе. В данной работе мы скорректировали применявшиеся ранее методы, отказались от использования временно-маршевого подхода и использовали метод адаптивного уточнения. Описаны три случая моделирования системы резервуар-труба-клапан, показывающие, что модель воспроизводит четкий градиент времени.
The manuscript presents the results of an application of a numerical method to solve one-dimensional hyperbolic equations. These equations simulate the dynamics of a liquid in a pipe with varying cross-sections. The equations are written in terms of pressure-head and discharge. Radial-basis functions and least-squares optimization are used for the numerical simulation. This numerical method is specialized for working with arbitrary nodal distribution in the problem domain. The basics of the application of the numerical method were introduced in our previous work. In the current work, we updated previously applied methods by means of getting rid of the time-marching approach and applying another adaptive refinement technique. Three cases of the simulations of the reservoir-pipe-valve system are described, indicating that the sharp time-gradient phenomenon is reproduced by the model.

В данной работе выполняется анализ высокой точности метода приведенного элемента Адини-Стокса, разработанного в [7], для модели Бринкмана. Мы показываем, что этот метод равномерно сходится с точностью порядка O(h2) для скорости в норме, зависящей от сетки и параметров, на общих квазиоднородных прямоугольных сетках. Также предлагается соответствующий метод постобработки для повышения точности для давления. Численные примеры подтверждают нашу теорию.
This work provides a high accuracy analysis of the reduced Adini Stokes element method developed in [7] for the Brinkman model. We show that this method is uniformly convergent for the velocity with convergence order O(h2) in a mesh- and parameter-dependent norm over general quasi-uniform rectangular meshes. A proper postprocessing technique is also proposed to improve the precision of the pressure. Numerical examples confirm our theory.
Factors influencing Prevention and Early Intervention within the Disability Claims Management Process in South Africa
Authors: Howell Kerri-Lee , Govender Pragashnie , Naidoo Deshini 
Published: February 2025

Introduction: The disability claims management process may be broken up into four stages: prevention, early intervention, rehabilitation and return to work. There are various stakeholders involved in the process and various factors that influence the process. Currently, there is a lack of literature that creates insight into the prevention and early intervention stages.Method: An explorative qualitative study was conducted with 26 purposively sampled stakeholders from the disability insurance sector. Qualitative data from virtual individual semi-structured interviews were inductively thematically analysed, using NVIVO Pro 12, to establish emergent themes.Results: Four inhibiting and four facilitating factors emerged from the data analysis. Inhibitors included: psycho-social-economic hardship, group insurer inhibitors, disability stigma and deconditioning and poor health and disability understanding. Facilitators included: group insurer facilitators, a remain-at-work (RAW) approach, medical and vocational management, and social and occupational support. The overarching theme emphasised disability as a complex phenomenon influenced by various medical and non-medical factors.Conclusions: The complexity of a disability contributes to the disability claims management process lacking focus on prevention and early intervention. Despite this complexity, retaining an employee at work while receiving early intervention emerged as a meaningful approach to decreasing the likelihood of the employee's ill health progressing to long-term disability.Â Key words: disability management, vocational management, disability income replacement insurance
Properties of Tungsten Carbide Rings When Compressed to Failure or Cut with a Diamond Grinding Bit
Authors: Quinto Ernesto S. , Reyes Nathan P. , Steimel Joshua P. , Lee JuEun , Dowbak John M. 
Published: February 2025

Background:
Tungsten carbide rings are increasingly popular modern jewelry items. Tungsten carbide is an extremely dense, hard metal. Previously described methods to remove tungsten carbide rings include using locking pliers to compress the ring or cutting the ring with a high-speed dental drill.

Methods:
A universal mechanical testing system (MTS) machine was used to diametrically compress tungsten carbide rings 9 mm in length and 2.4 mm in thickness with a 23.4-mm outer diameter and a 21.0-mm inner diameter while measuring the force required to fracture the rings. A computer numerical control (CNC) machine was used to cut tungsten carbide rings with a diamond grinding bit with and without a flow of normal saline solution. An infrared thermal camera was used to record the temperature at the site of contact between the ring and the grinding bit and at a site one-quarter of the circumference along the ring.

Results:
A mean force with 95% confidence interval of 3.7 ± 1.2 kN was required to fracture the tungsten carbide rings via diametral compression (p = 0.05). The rings failed at a mean displacement with 95% confidence interval of 0.32 ± 0.13 mm (p = 0.05). The maximum temperature observed at the site of contact between the ring and grinding bit averaged 160.2°C including cases with and without coolant. The time to reach maximum temperature and the duration of maximum temperature differed significantly between the cases with and without coolant (p = 0.0007 and p = 0.0108, respectively).

Conclusions:
Tungsten carbide rings fractured with minimal displacement using a small amount of force via diametral compression. The brittle fracture pattern of the rings produced minimal comminution. Tungsten carbide rings reached extreme temperatures when cut with a high-speed diamond grinding bit despite cooling with normal saline solution.

Clinical Relevance:
Previously documented methods to remove a tungsten carbide ring include breaking the ring by compressing it with pliers or cutting it off with a high-speed dental drill. Clinicians should be aware of potential complications of current methods to remove tungsten carbide rings.

Abstract

Cutaneous allergen sensitization (CAS) underlies atopic dermatitis (AD) and leads to various allergic symptoms, including food allergy and anaphylaxis. IL-13 expression by T follicular helper T (TFH) has been reported to be involved in generating high-affinity IgE antibodies and causing systemic anaphylaxis.1, 2 However, the mechanisms by which IL-13 triggers IgE-mediated allergic responses remain poorly defined. In the present study, we elucidate the role of IL-13 in the CAS-mediated mechanism by which high-affinity IgE antibodies are produced when the same allergen is introduced at a distal site in the secondary sensitization. The CAS model system using mice lacking the cell lineage-specific IL-13 receptor (IL-13R) demonstrated that dendritic cells (DCs), but not T or B cells, are critical in the high-affinity IgE-mediated anaphylactic response. The IL-13 signal in type 2 conventional DCs (cDC2s) enhanced the expression of MHC class II and CD301b, which was essential for the recall of type 2 responses, inducing the production of high-affinity IgE antibodies. Similar IL-13R-expressing DCs were identified in allergic rhinitis and food allergy patients with a history of AD. These findings strongly suggest the importance of DC-specific IL-13 signaling in CAS-induced allergic reactions associated with the atopic march, which is common in human AD patients.
The impact of simulation with debriefing on developing clinical competence and performance in paramedicine students
Authors: Veronese Jean-Paul , Crowther Grace , Lee Patricia , Boyle Malcolm 
Published: February 2025

Abstract

Introduction
Paramedics handle diverse medical and trauma cases, where any lapse in competency can compromise patient safety. Student paramedics must meet high standards set by oversight bodies to protect both the profession and the public. Growing evidence indicates that simulation facilitates attainment and reinforcement of clinical competencies. However, limited evidence explores the impact of simulation and debriefing on developing clinical competence in undergraduate paramedicine students.
Aim
This study aimed to evaluate the association between weekly practice session performance and summative practical exam outcomes, assessing how simulation-based practice supports the development of clinical competence among paramedicine students.
Methods
A retrospective analysis of performance-based assessment data (2019–2024) in a university paramedicine program evaluated the role of high-frequency simulation. Second-year students participated in weekly three hour simulated practice sessions and a summative practical exam, with performance assessed using the Clinical Competence Assessment Tool (CCAT). Practice session data were grouped into tertiles to assess trends. Pearson’s correlation measured the association between practice frequency and exam outcomes, paired samples t-tests evaluated performance progression, and hierarchical regression identified significant predictors of exam outcomes.
Results
Data from 305 students and 1,251 practice scenarios revealed a significant positive correlation between practice frequency and exam performance (rs = 0.257, p < 0.001). Clinical competence scores improved progressively across the trimester, with the strongest correlation observed in the final tertile (rs = 0.229, p < 0.001). Earlier tertiles showed weaker but statistically significant correlations (p < 0.05). A performance dip in 2020 due to reduced simulation exposure during COVID-19 further highlighted the critical role of consistent, high-frequency practice in fostering competence and exam success.
Conclusion
This study demonstrates the value of structured, high-frequency simulation and debriefing in enhancing clinical competence and exam performance. The findings underscore the importance of consistent practice, particularly in the final trimester weeks, supporting its integration into paramedicine curricula to ensure readiness for real-world practice and sustained competence.

Abstract

Current evidence of comparative clinical outcomes between translucent monolithic zirconia and lithium disilicate remains to be obtained to conclusively determine the superior material for fixed single-crown restorations.
Objectives: To comprehensively compare the three-year clinical outcomes of translucent monolithic zirconia and lithium disilicate in fixed dental prostheses.
Materials and Methods: We searched PubMed, EMBASE, Cochrane CENTRAL, CINAHL, and EBSCO Open Dissertations from inception to November 2023. Randomized controlled trials (RCTs) that compared the clinical outcomes of translucent monolithic zirconia and lithium disilicate in patients requiring fixed prostheses with a minimum follow-up of 6 months were included in this study. This systematic review and meta-analysis were developed and performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and with the guidance of the Cochrane Handbook for Systematic Reviews of Interventions (v.6.2). The risk of bias was assessed by the Cochrane Risk of Bias Tool 2 (RoB-2). This meta-analysis assessed the risk ratio (RR) for the effect size. Statistical analyses were performed via the RevMan5 software program. The protocol was registered with PROSPERO (CRD42023491978).
Results Of the 188 articles identified, four trials were included (n=4). The RRs [95% CIs] for all the outcomes were not significantly different between Tran Zr and LDS: survival rate (1.00 [0.98, 1.02], I2=0%), marginal integrity (0.98 [0.94, 1.02], I2=2%), absence of anatomical change (1.04 [0.98, 1.10], I2=0%), absence of dental caries (1.00 [0.99, 1.01], I2=0%), surface integrity (1.00 [0.92, 1.10], I2=0%), absence of crown fracture (1.00 [0.99, 1.02], I2=0%), absence of abutment fracture (0.99 [0.97, 1.01], I2=0%), and retention (0.98 [0.93, 1.03], I2=30%). The analysis demonstrated that translucent zirconia and lithium disilicate performed similarly across the evaluated outcomes over the 3-year follow-up period, with no significant differences detected.
Conclusions: Translucent zirconia and lithium disilicate have similar three-year survival rates without clinical significance, with either single posterior restorations or heavy bite forces on the multiunit restorations. This review also highlights the knowledge gap in the materials currently used for clinical trials. It requires more supporting evidence from other subjective parameters, such as color match, dentist or laboratory experience, material prices, and patient preferences.
