Evaluating Simultaneous Multi-threading and Affinity Performance for Reproducible Parallel Stochastic Simulation

This paper investigates whether simultaneous multi-threading (SMT) can improve performance on modern computing clusters with reproducible results on four types of applications, focused on stochastic simulations with different memory bound and compute bound constraints. We manually set the affinity of processes to compare its efficiency with the computing time obtained by the automatic assignment of the operating system. To measure SMT and affinity impact on a modern multicore processor, we parallelize up to 128 processes of the four types of applications. We expect repeatable numerical results between the sequential and parallel versions of simulations. For the three applications that are not memory bound, SMT is more effective by up to 30%. This represents an interesting increase up to 10% more performance for compute bound applications when compared to the initial papers discussing the efficiency of SMT. However, for the memory-bound application, SMT is less effective and can even decrease performance. The manual setting of core affinity does not show an increase in performance compared to the automatic assignment. All code and data used in the study are available to help reproducible research.
Biomechanical Motion of the Tennis Forehand Stroke: Analyzing the Impact on the Ball Speed Using Biofor Analysis Software

Background. The inefficiency of the forehand stroke technique often stems from suboptimal execution of an athlete’s biomechanical movements. For a forehand stroke to be effective, each biomechanical component – the ankles, knees, hips, shoulders, and elbows – must function in an optimal manner. Disconnection of any of these elements can lead to ineffective technique. High speed, influenced by the racket speed at the point of impact, is a key indicator of a perfect forehand stroke. However, the challenge lies in the fact that an athlete’s movement and ball impact cannot be accurately observed with the naked eye, necessitating specialized tools for analysis. Study purpose. The study aims to develop software that assists in predicting ball speed outcomes based on an athlete’s biomechanical movement during a forehand stroke execution. Materials and methods. The research method employed R&D. Data collection techniques consisted of video recordings of athletes’ forehand strokes, which were later analyzed using software that examines movement angles of 10 national athletes. Results. The results indicated the average angles of elbows = 106.23, shoulders = 153.62, hips = 165.33, knees = 167.63, ankles = 164.54; and ball speed = 199.41 cm/s. Conclusions. The conclusion drawn is that to execute an effective forehand stroke with good ball speed, a moment of inertia must occur at the point of impact. The athletes should bend their elbow slightly, thereby reducing rotational resistance and increasing the speed of the racket head. The ankles, hips, and shoulders must move in synchronization within a continuous coordination chain, thereby allowing the athlete to fully leverage kinetic chain. The flexion movement of the elbow during the forward swing step is more effective than the extension movement where the elbow is slightly bent, resulting in a perfect shot.
Chattering-Free Second Order Robustness Sliding Mode Controller for Complex Interconnected Systems: A Moore-Penrose Inverse Technique

In this paper, a novel second order sliding mode control approach is extended toa class of complex interconnected systems with mismatched interconnections and unknown perturbations. The key contribution of this paper is to cancel two common restrictions clogging the application of the variable structure control to complex interconnected systems: 1) all of state variables must be accessible; 2) the control input is affected by chattering problems. First, a novel reduced-order sliding mode estimator (ROSME) is proposed to estimate the unmeasurable variables. Second, based on Moore-Penrose inverse technique and ROSME tool, a new decentralized chattering-free second order robustness sliding mode controller (CSORSMC) is developed to force the system states to stay in a sliding surface from the initial period instance and attenuate the chattering phenomenon in the control signal. Besides, a novel appropriate linear matrix inequality (LMI) requirement is proved such that the plant in sliding mode is asymptotically stable. Lastly, a mathematical model including two subsystems is simulated which confirms the usefulness and advantages of proposed technique.
Describing Self-Reported Penicillin Allergy Using a Penicillin Allergy Risk Tool (PEN-FAST) in an Outpatient Setting at a Tertiary Hospital in Saudi Arabia

Introduction Penicillin is a widely used antibiotic and is frequently reported as a cause of allergic reactions. However, many individuals reporting penicillin allergies are later found to be tolerant. This study, conducted in an outpatient setting at King Abdulaziz University Hospital (KAUH) in Jeddah, Saudi Arabia, aimed to assess the prevalence of self-reported penicillin allergy and to evaluate further the risk of a positive penicillin allergy test using the PEN-FAST tool. Methods A cross-sectional study was conducted via in-person questionnaires with patients in the waiting area at the outpatient clinics of KAUH in Jeddah, Saudi Arabia. Results Among 140 participants, 4% reported a penicillin allergy, with most identifying their allergies based on symptoms. None of these allergies resulted in severe reactions. Notably, 50% reported nausea and itching as symptoms. The PEN-FAST tool categorized 33.3% as moderate risk and 50% as low to very low risk for a positive penicillin skin test. One participant was confirmed to be allergic via a skin prick test. Discussion and conclusion The prevalence of reported penicillin allergy was lower in our study than that previously reported. Evaluation of the PEN-FAST score demonstrated that this prevalence is even lower at 2%. While this single-center study offers valuable insights, further research in diverse healthcare settings is required to validate these findings and refine our understanding of penicillin allergies.
Chemical characteristics and influential factors of fluorine ions in shallow groundwater of Huaibei Plain

After analyzing the topography and geomorphology,the hydrogeological conditions,the chemical components(total hardness,salinity,and fluorine ion),and the hydro-chemical characteristics of the shallow groundwater in the Huaibei Plain,this study analyzed the F-content variation with pH,the total content of K+and Na+,the Ca2+ content,the(K++Na+)/Ca2+ ratio, and the Mg2+ content using statistical methods.It was found that that the F-content increases along with the pH value and is linearly related to the (K++Na+)/Ca2+ ratio,but no apparent correlation has been found between the F-content and the total K+and Na+content,the Ca2+ content,or the Mg2+ content.This paper also discusses the factors affecting F-and gives suggestions for reasonable utilization of groundwater resources.
Varved sediment responses to early Holocene climate and environmental changes in Lake Meerfelder Maar (Germany) obtained from multivariate analyses of micro X‐ray fluorescence core scanning data

We present an early Holocene record from Lake Meerfelder Maar in Germany for in‐depth interpretation of depositional changes in annually laminated lake sediments as proxies for climatic and local environmental changes. We characterized the compositional changes in the sediment record using Ward's clustering analyses of the micro X‐ray fluorescence core scanning data and linked these to microfacies descriptions. The down‐core distribution of the clusters allowed us to define boundaries that represent variations of a comprehensive element assemblage occurring at 11 555, 11 230, 10 650, 10 515 and 9670 varve a BP. Our main results show that during the Early Holocene the long‐term vegetation reorganization and evolution of the lake's catchment played a predominant role for sediment deposition. Abrupt shifts occurred at the Younger Dryas/Holocene and the Preboreal/Boreal biostratigraphical boundaries. We do not observe clear signals corresponding to known short‐term climatic oscillations described in the North Atlantic region such as the Preboreal Oscillation. A unique and intriguing episode in the history of the lake of predominantly organic deposition and very low amounts of allochthonous sediments occurred between 10 515 and 9670 varve a BP and is related to hydrological thresholds.
Why the Psychosomatic View on Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Is Inconsistent with Current Evidence and Harmful to Patients

Since 1969, Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) has been classified as a neurological disease in the International Classification of Diseases by the World Health Organization. Although numerous studies over time have uncovered organic abnormalities in patients with ME/CFS, and the majority of researchers to date classify the disease as organic, many physicians still believe that ME/CFS is a psychosomatic illness. In this article, we show how detrimental this belief is to the care and well-being of affected patients and, as a consequence, how important the education of physicians and the public is to stop misdiagnosis, mistreatment, and stigmatization on the grounds of incorrect psychosomatic attributions about the etiology and clinical course of ME/CFS.
Writing English Thesis in The Habitus New Normal Post Covid-19: Obstacles and Challenges from The Students’ Perspective

The majority of learning and teaching activities during the COVID-19 era were distributed to remote learners. The ineffectiveness of face-to-face instruction was subsequently put aside as students felt comfortable learning online. Policymakers in the education system had to adjust to a new normal or habit once the COVID-19 cases started to decline. The aim of this research is to identify the challenges faced by final year students in completing thesis during the Post-Covid-19 New Normal Habitus period and to find out how final year students can complete their thesis guidance during the Post-Covid-19 New Normal Habitus period. There were 15 English students joining the interview and the research was conducted within the State Islamic campus in Jambi City. Coding system was implemented to get credible data. The result shows that Completing studies in the New Normal Era has several obstacles. One of the most significant problems is the communication problem between students and supervisors which involves internal and external factors. Internal factors focus on difficulties caused by students' lack of understanding of thesis components, references and citation styles. Meanwhile, external factors focus on students' difficulties in the thesis writing process which depends on the direction of the supervisor, where some lecturers still provide online thesis guidance, where students agree that online counseling is not effective.
Tabata protocol-based high-intensity interval training in freestyle wrestlers

Background and Study Aim. The physical attributes of muscular strength and endurance are essential for wrestlers to perform successfully. For the development of these physical qualities, high intensity interval training (HIIT) using kettlebell strength exercises is appropriate. The purpose of this study was to develop a kettlebell HIIT program for wrestlers and evaluate the results on strength and endurance. Material and Methods. Eight freestyle wrestlers who participated in the Bulgarian Wrestling Championships (age: 22.0±2.17 years, wrestling experience: 9.9±2.80 years) were included in the study. Measurements included height, weight, 8 circumferences, 8 skinfolds, and BMI, body fat percentage (%BF), and skeletal muscle mass percentage (%SMM). The wrestlers engaged in an HIIT circuit that involved four rounds of 16 kg kettlebells and eight exercises, each lasting 20 seconds to complete and 10 seconds to recover between. Polar H7 was used to continually record heart rate (HR). At rest, before, immediately after, and 15 minutes after the HIIT, blood lactate concentration (La) was assessed. Each exercise's number of repetitions was noted. Results. The wrestlers' average height was 175.2±7.45 cm, their average weight was 85.1±13.38 kg, and their average BMI was 27.6 kg/m2. The SMM was 42.1±2.39%, and the BF was 10.3±3.98%. Heart rate (HR) exhibited a pattern of elevation from rest to warm-up and during circle 1 to 4, followed by a decrease 10 minutes after HIIT. Lactate levels (La) displayed an upward trend from rest to before HIIT, a significant increase after HIIT, and a decrease 15 minutes after HIIT. Conclusions. As shown by the fact that each wrestler's HR during the kettlebell HIIT was above 75% of HRmax and that La was above the anaerobic threshold (>4 mmol/L), the created kettlebell HIIT, when used 5 times per week for eight weeks as part of the wrestlers' training, can improve their endurance.
Factors Affecting the Likelihood of Dogs and Cats Returning to Their Owners at a Municipal Animal Shelter in the United States

Introduction: Animal shelters consider return-to-owner (RTO) as an ideal outcome for animals, owners, and shelters. Methods to increase RTO likelihood are frequently discussed by shelter professionals nationwide. Some of these methods are evidence-based, while others are anecdotally successful. This retrospective study aimed to provide evidence for commonly suggested methods, as well as identify additional factors influencing RTO likelihood. Methods: Data from 5,960 dog and 3,489 cat impounds were obtained from a large municipal animal shelter in Utah, USA. Directed acyclic graphs were developed to visualize causal assumptions, which were used to identify confounders for adjustment in the logistic regression while modeling the associations between study variables and RTO outcomes for both dogs and cats. Results: Dogs and cats with microchips, older animals, healthy animals, neutered animals, and animals brought to the shelter via another public agency were more likely to return to their owners. Animal sex and season of impound did not affect either dogs’ or cats’ RTO likelihood. Conclusion: The characteristics influencing RTO likelihood were similar for both dogs and cats. These influences provide support for existing shelter practices, such as facilitating widespread microchipping and waiving reclamation fees, while also encouraging implementation of new practices, such as modifying stray hold periods based on source type or health status. Limitations of the study included the presence of incomplete information in the database and concerns with the generalizability of results to other shelters.
Vitamin D Supplementation and Cardiovascular Disease Risks in More Than 134000 Individuals in 29 Randomized Clinical Trials and 157000 Individuals in 30 Prospective Cohort Studies: An Updated Systematic Review and Meta-analysis

Background: According to the findings from observational studies and clinical trials assessing the effect of vitamin D supplements on cardiovascular diseases (CVDs), there are still contradictory results. This systematic review aimed to assess the effect of vitamin D supplements on CVDs considering cohort studies and clinical trials. Study Design: A systematic review. Methods: MEDLINE/PubMed, Science Direct, Embase, and Cochrane Library databases were reviewed by two reviewers independently until 2022. The study effect is risk ratio (RR) and 95% confidence interval (CI) according to Mantel Haenszel’s random-effects model. Then, Stata version 14 was used for statistical analysis. Results: In clinical trial studies, the incidence of CVDs among the vitamin D-consuming group was not significantly different from that in the placebo group (RR: 0.99, 95% CI: 0.95-1.03; P=0.77; I 2=0%). CVD mortality was also not significantly different between the two groups (RR: 0.97, 95% CI: 0.90-1.05; P=0.72; I2=0%). In cohort studies, circulating 25 (OH) D increased the risk of CVD incidence by 31% (RR: 1.31, 95% CI: 1.19-1.45) and CVD mortality by 37% (RR: 1.37, 95% CI: 1.17-1.61). Conclusion: According to current evidence from clinical trials, vitamin D supplementation should not be recommended for CVD prevention. However, there is a direct association between vitamin D deficiency and the incidence of CVDs as well as its mortality. According to the results of clinical trial studies carrying higher levels of scientific evidence, it can be concluded that vitamin D supplementation does not exert a significant effect on the incidence, mortality, and reduction of CVDs.

Rheological Characteristics of Wheat Dough Containing Powdered Hazelnuts or Walnuts Oil Cakes

This study assessed edible oil industry byproducts, oil cakes (OC) based on hazelnuts and walnuts (HOC, WOC), to replace wheat flour dough (WD) based on farinograph and extensograph parameters and rheological measurements. The research hypothesis of this work is that replacing part of wheat flour with ground nut oil cakes modifies the rheological characteristics of the dough. WF was replaced at the level of 5%, 10% and 15%. It was shown that use of OC in flour mixtures at various levels significantly influenced the rheological properties of the dough. The water absorption of wheat flour and oil cake mixtures was higher than that of the control sample, and the average value of this indicator was 53.4%. The control sample had the lowest dough development time (DDT), and the presence of HOC or WOC in the system resulted in a significant increase in this parameter (p < 0.05). The average DDT of WDHOC cakes was 4.7 min and was lower compared to WDWOC which was 5.9 min. The WDWOC10% and WDWOC15% samples were characterized by the highest dough stability value and the lowest degree of softening (p < 0.05). The presence of OC in the flour mixtures increased the values of the storage and loss moduli, which was reflected in the K′ and K″ values. The values of these parameters also increased as the level of OC addition increased. WDHOC doughs were characterized by higher values of the K′ and K″ parameters compared to WDWOC. The results of the creep and recovery test showed that the dough with the addition of nut OC was less susceptible to deformation compared to the control dough (p < 0.05). The resistance to deformation increased with the increasing share of HOC or WOC in the mixtures. The average value of viscoelastic compliance (J1) of this parameter for WDHOC dough was on average 1.8 × 10−4 Pa−1, and for WDWOC 2.0 × 10−4 Pa−1. Nut oil cakes are an interesting technological addition to the dough. Their use may have a positive impact on the characteristics of the finished product and expand their application possibilities in the food industry. This is because the dough with the addition of nut cakes was more stiff and less flexible and susceptible to deformation.
