Authors: Tan Jing , Zhang Jianqin , Ma Mao , Sheng Binwu
Published: September 2024

The goal of this study was to investigate if there is an independent linear relationship between body mass index and gallbladder stone disease in obese people. In the years 2013–2019, 870 patients were recruited with new-onset asymptomatic gallbladder stone disease, and 870 healthy individuals at our university’s affiliated hospital for annual medical examinations were also included. We examined weight, height, blood pressure, fasting blood glucose, and serum lipid indices, and used logistic multivariate regression analysis to assess their relationships. Multivariate analysis revealed that body mass index, waist-to-height ratio, and hypercholesterolemia were all significant risk variables for gallbladder stone disease (P < 0.01, all) in pre-initial overweight subjects. In both overweight and obese subjects, waist-to-height ratio had a significantly positive relationship with gallbladder stone disease (P < 0.01, both); hypercholesterolemia had a similar effect on overweight participants (P < 0.01). After stratification by gender, serum total cholesterol and low-density lipoprotein cholesterol were significant risk factors in male overweight-obese participants (P < 0.05, both), but waist-to-height ratio and low-density lipoprotein cholesterol were equivalent in female overweight-obese subjects (P < 0.05, both). In conclusion, body mass index may be the best predictor for new-diagnosed asymptomatic gallbladder stone disease risk in the pre-initial overweight population without diagnosed diabetes, whereas abdominal adiposity may be during each phase.
Investigation of the Impact of a Chemical Reaction on the Magnetohydrodynamic Boundary Layer Flow of a Radiative Maxwell Fluid over a Stretching Sheet Containing Nanoparticles Employing the Variational Iteration Method
Authors: El Harfouf Amine , Wakif Abderrahim , Mounir Sanaa Hayani
Published: September 2024

The heat and mass transmission properties of a 2-D electrically conducting incompressible Maxwell fluid past a stretched sheet were studied under thermal radiation, heat generation/absorption, and chemical reactions. This issue has a variety of real-world applications, most notably polymer extrusion and metal thinning. The transport equations account for both Brownian motion and thermophoresis during chemical reactions. Using similarity variables allows for non-dimensionalization of the stream's PDEs and associated boundary conditions. The resulting modified ODEs are solved with the variational iteration approach. The impact of embedded thermo-physical variables on velocity, temperature, and concentration was studied quantitatively. When compared to the RK-Fehlberg approach, the findings are very similar. Raising the chemical reaction parameter narrows the concentration distribution, whereas increasing the temperature increases thermal radiation's impact. As the amount of N_t increases, the thickness of the boundary layer develops, causing the surface temperature to rise, resulting in a temperature increase.

Authors: Anusas-Amornkul Tanapat , Bussabong Naphat
Published: September 2024

A keystroke dynamics authentication uses keystroke rhythm for each user on a keyboard to verify a real user. The idea is that each user has a unique keystroke rhythm such that it can be determined the identity of a user. To verify a user, a keystroke vector dissimilarity technique was proposed to use keystroke features as a vector and calculate a weight using SoftMax+1 to overcome the Euclidean distance problem. However, the weight has yet to be analyzed in detail. Therefore, this paper aims to find a normalization technique and a weight adjustment to enhance the accuracy of the keystroke vector dissimilarity technique. The normalization techniques and activation functions analyzed in this study are Euclidean norm, Mean normalization, Min-max normalization, Z-score normalization, SoftMax function, and ReLU function. The weight adjustment varies from w+1000 to 1000-w. The results show that the Mean and Min-max normalizations with 10-w as a weight gave the same results at 96.97% accuracy and 3.03% error, which are better than the previous work.
Simulation Modeling of the Operation of the Toll Plaza with Reversible Lanes
Authors: Talavirya Alexander , Laskin Michael
Published: September 2024

The construction of toll roads depends on the available territory. The limited area often does not allow the construction of a full-fledged toll plaza (hereinafter referred to as TP) with high capacity and many lanes. In such cases, the configuration of TP is linked with the configuration of reversible lanes. Reversible lanes carry traffic and help optimize traffic flow. The challenge is to choose the optimal configuration of a TP that provides the highest capacity (traffic flow increases in both directions) and helps control operators’ errors resulting in traffic congestion problems. The present study estimates TP with reversible lanes throughput capacity in different configurations and traffic flow parameters. The study employs discrete-event simulation modeling in the AnyLogic software environment. Our results show the optimal configuration of the reversible lanes and explain what traffic flow parameters affect their capacity. The paper concludes with practical recommendations on how to effectively apply simulation modeling to a TP operation and optimize it.

A hierarchical reinforcement learning model explains individual differences in attentional set shifting
Authors: Talwar Anahita , Cormack Francesca , Huys Quentin J. M. , Roiser Jonathan P.
Published: September 2024

Attentional set shifting refers to the ease with which the focus of attention is directed and switched. Cognitive tasks, such as the widely used CANTAB IED, reveal great variation in set shifting ability in the general population, with notable impairments in those with psychiatric diagnoses. The attentional and learning processes underlying this cognitive ability and how they lead to the observed variation remain unknown. To directly test this, we used a modelling approach on two independent large-scale online general-population samples performing CANTAB IED, with one including additional psychiatric symptom assessment. We found a hierarchical model that learnt both feature values and dimension attention best explained the data and that compulsive symptoms were associated with slower learning and higher attentional bias to the first relevant stimulus dimension. These data showcase a new methodology to analyse data from the CANTAB IED task, as well as suggest a possible mechanistic explanation for the variation in set shifting performance, and its relationship to compulsive symptoms.

Published: September 2024

Este artículo de revisión tiene como objetivo analizar el impacto del Diseño Universal de Aprendizaje (DUA) en la inclusión educativa, abordando tres áreas clave: accesibilidad, rendimiento académico y participación estudiantil. A través de una revisión sistemática de estudios publicados en los últimos cinco años en bases de datos como Scopus, Web of Science y ERIC, se siguió la metodología PRISMA para garantizar un proceso riguroso y replicable. Se identificaron y analizaron 35 estudios que cumplieron con los criterios de inclusión, proporcionando una visión integral sobre los efectos del DUA en diferentes contextos educativos. Los principales hallazgos revelan que el DUA mejora significativamente la accesibilidad al contenido educativo, especialmente mediante el uso de tecnologías asistivas. Asimismo, se evidenció un aumento en la participación y el compromiso de los estudiantes, gracias a la flexibilidad pedagógica que ofrece el DUA. Sin embargo, los resultados relacionados con el rendimiento académico son más variados, dependiendo en gran medida de la calidad de la implementación y los recursos disponibles. Se concluye que, aunque el DUA es una herramienta poderosa para promover la inclusión, su efectividad depende de la formación docente, los recursos tecnológicos y la planificación pedagógica.

En este estudio se pretendió analizar el rezago escolar postpandemia COVID 19, como elemento inhibidor del rendimiento académico, con el objetivo dediseñar un programa de estrategias para mitigar el rezago escolar postpandemia COVID- 19, que actúa como elemento inhibidor del rendimiento académico, tomando en cuenta las causas, influencia e incidencia social y emocional en los estudiantes de la Unidad Educativa Prócer Manuel Quiroga durante el año lectivo 2022- 2023. Por medio de encuestas aplicadas a los estudiantes y docentes analizadas por medio del programa SPSS, se logró comprender cuales fueron las causas, influencia e incidencia social que acrecentaron el RE y cuáles son las estrategias con mejores resultados a aplicadas para superar están: la dificultad de aprendizaje, la falta de aparatos tecnológicos, la inserción laboral a temprana edad y la falta de motivación al estudiante. Respecto a la influencia e incidencia social y emocional, se evidenció que la situación económica, la edad que no estaba acorde al nivel académico y el aislamiento social fueron determinantes y de mayor afectación entre los estudiantes. Por último, se pudo apreciar que la mejor estrategia para terminar con el rezago escolar es la aplicación de refuerzos académicos según las falencias que cada estudiante y según su nivel académico, la entrega del bono de desarrollo humano. En la correlacional de Pearson se determinó que las dos variables son inversamente proporcionales, es decir a mayor rezago escolar menor rendimiento académico.

The Onega Peninsula in the White Sea, north-western Russia, is a habitat for ecologically and economically significant salmonid species, i.e. Atlantic salmon Salmo salar Linnaeus, 1758 and brown trout S. trutta Linnaeus, 1758 (Salmoninae). However, these populations are currently understudied in terms of molecular approach. In this work, we assessed the genetic diversity and differentiation of S. salar and S. trutta from the eastern part of the Onega Peninsula based on mitochondrial (COI and cytb) and nuclear (RAG1) markers. We also traced a phylogeographic pattern of these species. Populations of brown trout in the studied watercourses mainly share low haplotype and nucleotide diversity, with the exception of the moderate values in the Gosdarea River. In turn, Atlantic salmon in the Ust’-Yaren’ga River has higher genetic diversity than brown trout. Our study reveals great importance of conservation measures and monitoring, as well as parasite pressure control, especially for brown trout, in the eastern part of the Onega Peninsula.

Authors: Afandy Moh , Mubarak Abdul Haris , Rianto Muhammad Ikbal
Published: September 2024

The Electric Arc Furnace (EAF) transformer is a key component in the steel melting system using a furnace. The transformer functions to convert the electrical voltage from the main electrical network into the electrical voltage needed to form an electric arc in the melting furnace. In this research, the EAF transformer configuration uses a delta-wye configuration with a furnace melting capacity of 10 kg nickel ore. In its working system, this transformer will produce a very high current when the melting system is running. So this process will produce excessive heat on the EAF transformer side. As a result of the significant heat generated in the melting process, this transformer is equipped with a cooling system in the form of transformer oil which is a heat release medium and maintains the correct operating temperature. An appropriate temperature monitoring system will increase the work efficiency of the transformer and prevent excessive damage to the system. The sensor used in the design is the RTD PT 100 sensor which is installed at 7 measurement points. The main controller for data collecting and data processing used is a Siemens PLC. Data that has been processed on the main control device is transmitted to the IoT cloud server using a V-box device. As a human machine interface (HMI) web SCADA is used to read data in real time. From the results of the tests that have been carried out, the highest error presentation value obtained in measurements on the T phase is 0.05%. Meanwhile, when measuring the transformer oil sensor, an error value of 0% was obtained.

Equipment includes; Weighing balance of 0.1g accuracy, sieve no 2020 (75pm) stirring rod, brushes and spray. In this phase soluble rubber was tried differently with the materials in various oxide composition applied on the existing CSEB walling unit, from observation some performed well while others performed moderately. The second and the third phase of the trial employed limestone and hydrated lime (Ca (OH)2 as the main stabilizer to activate reaction between the combination of any of the samples that contained high silica and a certain percentage of aluminium oxide (Al2CO3) x H2O(c) to produce an effective result as the Ca (H2O(s)) react in the presence of air to give Ca2SiO3(s) a solid that is stable in water, and applied on CSEB wall surfaces for observation across wet and dry Season.

Since midgut volvulus is a rare but serious condition featuring twisted intestines, this presents significant problems with diagnosis and treatment- especially for adults. Early diagnosis and swift action are important in preventing such complications as juxtaposition of the bowel loops with volvulus, necrosis, etc. This study is based on recent developments of a case documented in then Jordanian American Physicians Academy Journal, and makes clear the difficulties involved in diagnosing midgut volvulus in a patient with cavernous transformation of the portal vein. Entering oublic health and reaching out to each discipline, means T.The fact that this study involved adult and pediatric cases demonstrates the need for advanced imaging technology and individualized treatment plans in order to improve patient outcomes.

Times of minima of eclipsing binary KIC 7023917 show quasiperiodic anti-symmetric deviations from the calculated one with an amplitude of up to 10 minutes and a period of 200–300 days. These changes correlate with the observed variations of the light-curve maxima (amplitude and phase separation). We used photometric data obtained by Kepler and TESS missions to analyze the times of minima and determine system parameters. The phases and amplitudes of the maxima were measured to study the O’Connell effect. As an additional source of information, we performed ground-based multicolor photometric observation and determined the radial velocities of the system from our spectroscopic measurements. We could explain long-term variations of the light-curve shape and times of the eclipses using the cold star spot located on the secondary component and the modification of its size. Based on our modelling, the system consists of a primary main-sequence star of spectral type A7 and an evolved, oversized secondary component with a mass ratio of only 0.1 due to past mass transfer. Calculation of absolute parameters gives us the mass of the primary component about 1.8 M
☉ and 0.2 M
☉ for the secondary one, and radii of 2.2 R
☉ of the primary star and 0.9 R
☉ of secondary one, respectively. The studied low-mass ratio eclipsing binary is probably a progenitor of the variable star of EL CVn type. A multiple-period photometric variability was disclosed in the TESS data ranging from half to two hours due to δ Scuti-type pulsations of the primary component.
Accurate Measurement of the Lensing Magnification by BOSS CMASS Galaxies and Its Implications for Cosmology and Dark Matter

Magnification serves as an independent and complementary gravitational lensing measurement to shear. We develop a novel method to achieve an accurate and robust magnification measurement around BOSS CMASS galaxies across physical scales of 0.016h
−1 Mpc < r
p < 10h
−1 Mpc. We first measure the excess total flux density δ
M of the source galaxies in the deep DECaLS photometric catalog that are lensed by CMASS galaxies. We convert δ
M to magnification μ by establishing the δ
μ–δ
M relation using a deeper photometric sample. By comparing magnification measurements in three optical bands (grz), we constrain the dust attenuation curve and its radial distribution, discovering a steep attenuation curve in the circumgalactic medium of CMASS galaxies. We further compare dust-corrected magnification measurements to model predictions from high-resolution dark matter-only (DMO) simulations in Wilkinson Microwave Anisotropy Probe (WMAP) and Planck cosmologies, as well as the hydrodynamic simulation TNG300-1, using precise galaxy–halo connections from the Photometric objects Around Cosmic webs method and the accurate ray-tracing algorithm P3MLens. For r
p > 70h
−1 kpc, our magnification measurements are in good agreement with both WMAP and Planck cosmologies, resulting in an estimation of the matter fluctuation amplitude of S
8 = 0.816 ± 0.024. However, at r
p < 70h
−1 kpc, we observe an excess magnification signal, which is higher than the DMO model in Planck cosmology at 2.8σ and would be exacerbated if significant baryon feedback is included. Implications of the potential small scale discrepancy for the nature of dark matter and for the processes governing galaxy formation are discussed.

The properties of warm-hot gas around ∼L
* galaxies can be studied with absorption lines from highly ionized metals. We predict Ne viii column densities from cosmological zoom-in simulations of halos with masses in ∼1012 and ∼1013
M

M
☉ halos. In ∼1013
M
☉ halos the Ne viii gas is clumpier, and biased toward the cooler part of the warm-hot phase. We compare the simulations to observations from the COS Absorption Survey of Baryon Harbors (or CASBaH) and COS Ultraviolet Baryon Survey (or CUBS). We show that when inferring halo masses from stellar masses to compare simulated and observed halos, it is important to account for the scatter in the stellar-mass–halo-mass relation, especially at M

M
☉. Median Ne viii columns in the fiducial FIRE-2 model are about as high as observed upper limits allow, while the simulations analyzed do not reproduce the highest observed columns. This suggests that the median Ne viii profiles predicted by the simulations are consistent with observations, but that the simulations may underpredict the scatter. We find similar agreement with analytical models that assume a product of the halo gas fraction and metallicity (relative to solar) ∼0.1, indicating that observations are consistent with plausible circumgalactic medium temperatures, metallicities, and gas masses. Variants of the FIRE simulations with a modified supernova feedback model and/or active galactic nuclei feedback included (as well as some other cosmological simulations from the literature) more systematically underpredict Ne viii columns. The circumgalactic Ne viii observations therefore provide valuable constraints on simulations that otherwise predict realistic galaxy properties.

This paper demonstrates the impact of state-of-the-art instrumental calibration techniques on the precision of arrival times obtained from 9.6 yr of observations of millisecond pulsars using the Murriyang 64 m CSIRO Parkes Radio Telescope. Our study focuses on 21 cm observations of 25 high-priority pulsars that are regularly observed as part of the Parkes Pulsar Timing Array project, including those predicted to be the most susceptible to calibration errors. We employ measurement equation template matching (METM) for instrumental calibration and matrix template matching (MTM) for arrival time estimation, resulting in significantly improved timing residuals with up to a sixfold reduction in white noise compared to arrival times estimated using scalar template matching and conventional calibration based on the ideal feed assumption. The median relative reduction in white noise is 33%, and the maximum absolute reduction is 4.5 μs. For PSR J0437−4715, METM and MTM reduce the best-fit power-law amplitude (2.7σ) and spectral index (1.7σ) of the red noise in the arrival time residuals, which can be tentatively interpreted as mitigation of 1/f noise due to otherwise unmodeled steps in polarimetric response. These findings demonstrate the potential to directly enhance the sensitivity of pulsar timing array experiments through more accurate methods of instrumental calibration and arrival time estimation.
Le patrimoine photographique de l’ancienne famille royale de Pudukkottai (Tamil Nadu) : un outil de légitimité
Authors: Dumas Valentine
Published: September 2024

L’utilisation de la photographie par les Tondaiman, ancienne famille royale de Pudukkottai (Tamil Nadu, Inde du Sud), s’est développée dès 1858 et répondit à des usages sociaux variés. La position sociale de cette famille fut redéfinie après l’indépendance de 1947. Son appropriation de la photographie, l’amélioration de sa conservation ainsi que sa mise en circulation progressive entraînèrent des évolutions dans la mise en valeur du patrimoine photographique familial et permirent aux Tondaiman de renforcer leur statut au sein de la société locale.

Dans les années 1960, en Lettonie soviétique, des urbanistes arpentent les marges urbaines dont ils doivent imaginer l’aménagement, appareil photographique en bandoulière. En s’appuyant sur un corpus de 300 clichés, cet article documente ces enquêtes de terrain et les conditions de production et d’utilisation des images. Il montre les possibilités qu’offre la photographie, dans un régime autoritaire, pour limiter l’emprise de l’État technocratique et bureaucratique sur des pratiques professionnelles.
