Authors: Rastogi Devarshi , Shantanu Kumar 
Published: November 2024

Abstract
Hemophilic arthropathy is a common complication of hemophilia A and can lead to chronic synovitis, joint damage, and eventually ankylosis. We present a case report of a 39-year-old male patient with a history of recurrent hemorrhages into the joints. He had a history of traumatic injury to both upper limbs and lower limbs. The patient was on bed rest for 6 months. Subsequently, he developed ankylosis of both elbows in 30° of flexion and ankylosis of the right (Right) knee in 40° of flexion with tricompartmental arthritis of the left knee joint. Radiologically, the left knee joint showed reduced joint space with tricompartmental arthritis. The patient was managed by the tumor prosthesis for the Rt knee. He was advised for management of the elbow joints for which he was not willing. Postoperatively, he was allowed knee range of motion exercises and walking with a walker for 4 weeks followed by a stick for 1 month. At 6-month follow-up, he was able to walk effortlessly without support. The Knee Society Score improved from 47 preoperatively to 75 at 6-month follow-up.

Published: November 2024

Due to its flexibility, the skew distributions (univariate and multivariate) have received widespread attention over the last two decades because they're become widely used in the modelling and analysis of skewed data sets. The main goal of this paper is to introduce asymptotic expressions for entropy of multivariate skew Laplace normal distribution to deal with the issue by providing a flexible model for modeling skewness and heavy tiredness simultaneously. Thus, we extend this study to the class of mixture model of these distributions. In addition, upper and lower bounds of Rényi entropy of mixture model are found, by using generalized HӦlder’s inequality and some properties of multinomial theorem.. Finally, we give a real data examples to illustrate the behavior of information. A simulation study and a real data example, are also provided to illustrate the information behavior of MSLN and MMSLN distributions for modeling data sets in multivariate settings

Published: November 2024

Abstract
In this article, we use the Sinc approximation to solve the single Poisson problem (where the first derivative or higher order does not have an exact answer on the border of the boundary). We have examined the Sinc Galerkin approximation to solve the single Poisson problem, and finally, to solve the Poisson problem, we will use the sinc collocation method and in this method, we will reach a linear system. By carefully choosing the length of the steps and the number of nodal points, we will solve this system with two methods, with the orthogonalization technique, a numerical approximation will be obtained. Its accuracy can be exponential and of order where is a transaction parameter and c are a constant independent of N. In the final part, we will give some numerical examples of single Poisson problems.

Authors: Nikolaenko Viktor A. , Sokolov Sviatoslav S. 
Published: November 2024

Known in nanoelectronics a solid-state quantum size systems motivate creating like systems using the surface electrons on liquid helium. The quantum carry of quasi-one-dimensional surface electrons (Q1D-SEs) over superfluid helium is considered here. Research is conducted based on an electron phase diagram in the gas phase under conditions far from electron quantum melting. A substrate is dense row of the light guide segments where the SEs channels are formed over helium in the fiber gaps between. The electrostatic model of substrate profile demonstrates modulation of potential in the electric field leading to possibility of the fiber top charge thereby improving the Q1D-SEs channels' quality. The experiments carried out by a low-frequency electron transport method at the temperature from 1.5 K to 0.5 K and the concentrations of electrons were up to 109cm−2. The SE movement transverse to the channel satisfies quantization conditions in terms of both temperature and electron relaxation time in the system. According to the experiment, below a certain temperature, the SE conductivity is ladder-like. The differential of SE conductivity is peak-like corresponding qualitatively to an electron states density. The distance between peaks accords to the 1D energy spectrum in some approach. Possibility of applying the 1D-SEs quantized energy levels (vibration levels) as quantum bits for a quantum computer is considered.

Высокие темпы социально-экономического развития регионов Казахстана невозможны без высокого уровня эффективности управления в вузах. Обучение инженеров в региональных вузах должно соответствовать отраслевой специфике конкретных областей и фокусироваться на разработке компетенций, необходимых для решения конкретных проблем и внедрения технологий, актуальных для производств. Анализ показал, что регионы имеют разную специализацию своих экономик. Такие различия в региональном развитии являются ключевым фактором, который необходимо учитывать при организации инженерной подготовки. Высокий спрос на конкретные инженерные навыки из-за особенностей отраслевой структуры экономики региона ведет к необходимости уделять внимание развитию специализированных навыков при подготовке инженерных кадров. В случае, если у региональных различий есть экологический или социальный аспект, обучение инженеров должно поддерживать принципы устойчивого развития, специфичные для конкретного региона. Тем самым, учет региональных особенностей в инженерной подготовке позволит обеспечить более эффективное соответствие компетенций выпускников вузов требованиям местного рынка труда, что, несомненно, будет способствовать устойчивому и сбалансированному развитию экономики регионов Казахстана. В целом можно сказать, что качественная подготовка инженерных кадров, ориентированная на соблюдение принципов и целей устойчивого развития, будет способствовать достижению более сбалансированного и эффективного развития экономики регионов и страны. Ключевые слова: инженерные кадры, устойчивость экономики региона, сбалансированность регионального развития, региональные вузы, экономика промышленности, экологическая политика.

Published: November 2024

IntroductionThe objective of this cross-sectional study was to evaluate the monocyte to albumin ratio (MAR), neutrophil to albumin ratio (NAR), platelet to albumin ratio (PAR), and C-reactive protein to albumin ratio (CAR) as potential biomarkers for disease activity in patients with Behçet’s disease (BD).Material and methodsBoth BD cases and healthy controls were enrolled in this study. Demographic characteristics, disease duration, and current medications were recorded for all participants. The BD Current Activity Form (BDCAF) was utilized to assess the activity of BD. Additionally, ery­throcyte sedi­mentation rate, CRP, and serum albumin levels were measured. The MAR, NAR, PAR, and CAR were compared between the two groups. Correlation analysis and receiver operating characteristic curves (ROC) were employed to establish cut-off points for these biomarkers.ResultsIn the study, both BD cases and 45 controls were included, totaling 90 participants. Significant differences were observed in the mean ±SD values of ESR, MAR, PAR, CAR, and albumin between the BD cases and controls (<i>p</i> = 0.008, <i>p</i> = 0.009, <i>p</i> = 0.029, <i>p</i> = 0.034, <i>p</i> = 0.006, respectively). However, despite these differences, no significant correlation was detected between BDCAF and the parameters under investigation. The cutoff point was determined as 150.59 (sensitivity 46.67%, specificity 82.22%, <i>p</i> = 0.008, AUC = 0.655) for MAR; as 62,013.73 (sensitivity 60.00%, specificity 66.67%, <i>p</i> = 0.03, AUC = 0.629) for PAR; and as 1.16 (sensitivity 35.56%, specificity of 95.567%, <i>p</i> = 0.03, AUC = 0.629) for CAR. The results were not able to define any cut-off points for active-inactive BD.ConclusionsSignificantly higher levels of MAR, PAR, and CAR were observed in patients with BD than controls. Monocyte to albumin ratio, PAR, and CAR were notably elevated in patients with active BD. This finding suggests that these parameters possess discriminative ability and could potentially serve as biomarkers to aid in the clinical evaluation of BD.

Introducción. El potencial dendrocronológico de una especie revela su capacidad para desarrollar anillos de crecimiento anuales con una fuerte señal climática.
Objetivo. Evaluar el potencial dendrocronológico de Pinus pinceana Gordon para registrar la variabilidad climática en sus anillos de crecimiento.
Materiales y métodos. Se extrajeron núcleos de crecimiento de P. pinceana en un matorral submontano en Tamaulipas, México. Se usaron programas dendrocronológicos para la medición del ancho anual de los anillos, su fechado y su transformación a índices de crecimiento. Estos índices se relacionaron con datos de precipitación y de temperatura.
Resultados y discusión. La correlación entre series fue r = 0.54 (p < 0.001) y la sensibilidad media de 0.31. Estos valores son más bajos que lo documentado para la especie; sin embargo, indican que esta es sensible a los factores climáticos y capaz de registrar su variabilidad a través del grosor de los anillos de crecimiento. Se generó una cronología de 153 años (1867-2019) con potencial para detectar la variabilidad de la precipitación promedio acumulada septiembre-mayo (r = 0.71; p < 0.001) y de temperatura máxima promedio septiembre-junio (r = -0.64; p < 0.001). El piñonero llorón en Tamaulipas supera la sensibilidad a la precipitación que la especie presenta en otras poblaciones del centro y norte de México.
Conclusiones. P. pinceana en Tamaulipas tiene un buen potencial dendrocronológico por la capacidad de registrar, en sus anillos de crecimiento, la variabilidad climática de la región, particularmente la precipitación.

Particulate emissions from cooking: emission factors, emission dynamics, and mass spectrometric analysis for different cooking methods

Published: November 2024

Abstract. Since most people, especially in developed countries, spend most of their time indoors, they are heavily exposed to indoor aerosols, which can potentially lead to adverse health effects. A major source of indoor aerosols are cooking activities, which release large quantities of particulate emissions (in terms of both number and mass), often with complex compositions. To investigate the characteristics of cooking emissions and what influences these emissions, we conducted a comprehensive study by cooking 19 dishes with different ingredients and cooking methods. The emissions were monitored in real time with several online instruments that measured both physical and chemical particle properties as well as trace gas concentrations. The same instrumentation was used to study the influence of cooking emissions on the ambient aerosol load at two German Christmas markets. In contrast to previous studies, which often focus on individual aspects or emission variables, this broad and coherent approach allows a comparison of the influence of different parameters (e.g., ingredients, cooking method, cooking temperature, cooking activities) on the emissions. We found an influence of cooking emissions on six variables: number concentration of smaller (particle diameter dp > 5 nm) and larger (dp > 250 nm) particles, particulate matter (PM: PM1, PM2.5, PM10), black carbon (BC), PAHs (polycyclic aromatic hydrocarbons), and organic aerosol mass concentration. In general, similar emission characteristics were observed for dishes with the same cooking method, mainly due to similar cooking temperature and use of oil. The temporal dynamics in the emissions of the aforementioned variables, as well as the sizes of the emitted particles, were mainly influenced by the cooking temperature and the activities during cooking. Emissions were quantified using emission factors, with the highest values for grilled dishes, 1 to 2 orders of magnitude lower for oil-based cooking (baking, stir-frying, deep-frying), and the lowest for boiled dishes. For the identification of cooking emissions with the Aerodyne aerosol mass spectrometer (AMS), and more generally for the identification of new AMS markers for individual organic aerosol types, we propose a new plot type that takes into account the mass spectral variability for individual aerosol types. Combining our results and those of previous studies for the quantification of cooking-related organic aerosols with the AMS, we recommend the use of relative ionization efficiency values higher than the default value for organics (RIEOrg = 1.4): 2.17 ± 0.48 for rapeseed-oil-based cooking and 5.16 ± 0.77 for soybean-oil-based cooking.
