Compressible turbulence in space and astrophysical plasmas : Analytical approach and in-situ data analysis for the solar wind

My thesis work is principally dedicated in understanding the role of compressibility in lowfrequency turbulence of space plasmas (the solar wind, magnetospheric plasma etc.) and astrophysical plasmas (interstellar molecular cloud, the core of a star etc.). Three new exact relations have been derived analytically in the framework of isothermal and polytropic hydrodynamic turbulence and also for an isothermal MHD plasma. By using these relations, various universal scalingproperties of compressible turbulence have been investigated. In addition, plausible phenomenologieshave been proposed in order to theoretically reproduce different power laws for energy power spectra which had been obtained in previous numerical simulations of compressible turbulence. A semi-qualitativedistinction between sub-sonic and supersonic regime of turbulence is hence concluded. In the second part, an analysis using THEMIS spacecraft data is also performed in a view to explainingthe effect of the compressibility in the turbulence of the fast solar wind. A remarkable smooth scalingin comparison with incompressible law is obtained for several intervals of fast solar wind. The corresponding turbulent energy flux is also found to be sufficient to explain the anomalous heating of fast solar wind.
International Journal of Speleology digital 3D models of Algar do Penico Chamber: limitations, challenges, and potential

: The study of karst and its geomorphological structures is important for understanding the relationships between hydrology and climate over geological time. In that context, we conducted a terrestrial laser-scan survey to map geomorphological structures in the karst cave of Algar do Penico in southern Portugal. The point cloud data set obtained was used to generate 3D meshes with different levels of detail, allowing the limitations of mapping capabilities to be explored. In addition to cave mapping, the study focuses on 3D-mesh analysis, including the development of two algorithms for determination of stalactite extremities and contour lines, and on the interactive visualization of 3D meshes on the Web. Data processing and analysis were performed using freely available open-source software. For interactive visualization, we adopted a framework based on Web standards X3D, WebGL, and X3DOM. This solution gives both the general public and researchers access to 3D models and to additional data produced from map tools analyses through a web browser, without the need for plug-ins.

Leaving the Lectures Behind: Using Community-Engaged Learning in Research Methods Classes to Teach about Sustainability

This article explores the outcomes of using community-engaged learning in a sustainability-focused social sciences research course titled Methods of Social Research. The integrated components of the course were designed to teach students about the research process while addressing sustainability issues at Utah State University. Throughout the course, students learned how to collect, analyze, and interpret data; work in research teams; write a grant; and write and present a final research paper. Student sustainability surveys and the final course evaluation were used to analyze student learning outcomes. We found that students demonstrated increased confidence in collecting, analyzing, and interpreting data and an improved effectiveness and enjoyment in working in teams toward a final product. Students also exhibited their knowledge of small- and large-scale sustainability challenges as well as a decisiveness in answering questions related to sustainability. These outcomes resulted in heightened student self-efficacy and critical thinking skills when performing research and engaging with issues related to sustainability.
High resolution solar flare x-ray spectra: the temporal behavior of electron density, temperature, and emission measure for two class m flares. Technical report

High resolution soft X-ray flare spectra recorded by Naval Research Laboratory (NRL) and Aerospace Corporation Bragg crystal spectrometers flown on an orbiting spacecraft (P78-1) are combined and analyzed. THe instruments were launched on 1979 February 24 by the U.S. Air Force, and the data discussed in this paper cover the wavelength ranges, 1.82--1.97 A, 3.14--3.24 A, and 18.4--23.0 A. The NRL experiment (SOLFLEX) covers the two short wavelength ranges (highly ionized Fe and Ca lines) and the Aerospace experiment (SOLEX) covers the 18.4--23.0 A range, which includes the Ly.cap alpha. O VIII line and the resonance, intercombination, and forbidden lines of O VII. We analyze the spectra of two flares which occurred on 1980 April 8 and May 9. Temporal coverage is fairly complete for both flares, including the rise and decay phases. Measurements of electron density N/sub e/ with rather high time resolution (about 1 minute) have been obtained throughout most of the lifetime of the two flares. These measurements were obtained from the O VII lines and pertain to flare plasma at temperatures near 2 x 10/sup 6/ K. Peak density seems to occur slightly before the times of peak X-ray flux in the resonance lines of Femore » XXV, Ca XIX, and O VII, and for both flares the peak density is about 10/sup 12/ cm/sup -3/. Electron temperature T/sub e/ as a function of time is determined from the Fe and Ca spectra. Peak temperature for both flares is about 18 x 10/sup 6/ K. Differential emission measures and volume emission measures are determined from the resonance lines of O VII, Ca XIX, and Fe XXV. The number of electrons N/sub e/. delta.V and the volume . delta.V over which the O VII lines are formed are determined from the O VII volume emission measure N/sub e//sup 2/. delta.V and the density N/sub e/. These quantities are determined as a function of time. The relationship of the low and high temperature regions is discussed. « less
Design of Health Detection System for Elderly Smart Watch Based on Biosignal Acquisition

The health monitoring of the elderly has attracted increasing attention of researchers. Based on the biosignal acquisition method, this paper proposes a design structure of the health detection system for smart watches for the elderly and realizes the effective detection of health signals by analyzing the Lipschitz exponent of the maximum value column of the transform. The multiphysiological parameter acquisition and monitoring system of the wearable smart watch designed in this paper can continuously monitor the physiological parameters of the elderly such as body temperature, pulse, and respiration for a long time and solve the problem of the accuracy of the health detection of the elderly. In the simulation process, based on the performance of the synchronization source and the difference of the network path, the model applies the multivariate and multiscale biological signals to collect the human gait acceleration. The experimental results show that, compared with the international recognition rate obtained for this data set, the highest recognition rate obtained by the method in this paper reaches 96.5%, which can provide a calibration accuracy of 1 ~ 50 ms, and the synchronized system time and the national time service center network are given. The error obtained by comparing the published time is within 50 ms, which meets the accuracy requirements of the time protocol. The results fully prove that the algorithm in this paper can effectively extract the biosignal features of the elderly’s health detection and has good statistical features and classification accuracy.
Prevalence and Molecular Characterization of Dral 1 gene of Schistosoma haematobium Associated with Pathogenesis of Human Urinary Schistosomiasis among School Pupils in Cross River State, Nigeria

Urinary schistosomiasis which is transmitted by schistosome species is the major cause of liver and bladder pathologies and still remains a serious threat in the underdeveloped and developing world. This study evaluates the prevalence of Schistosoma haematobiuminfection among school aged children in Biase, Obubra and Ogoja Local Government Areas of Cross River State. Five hundred (500) pupils were examined and selected randomly from a public primary and secondary schools in the study area. Freshly passed mid-day urine samples were collected and transferred to the laboratory where there were examined for the presence of Schistosoma haematobium eggs. Study participants were grouped into three age groups,8-10 years. 11-13 years, and 14-16 years old. Overall prevalence of S. heamatobium was (13.6%). Infection was more prevalent among the age group of 14-16years, the percentage of prevalence and intensity of infection were higher in males (14.1%) than in females (6.9%). Inter simple sequence repeats of PCR test performed for the collected urine samples using ISSR test of the Dral-1 gene reveals 73% study subjects had a polymorphism for UPA02 and UPA13 primers, while primer UPA13 showed 24% polymorphism. Total number of polymorphic bands were 2 each for primers UPA02 and UPA13 primers while UPA12 showed only one polymorphic band. Major allele frequencies (MAF) were 0.53 for each of UPA02 and UPA 13 primers but showed 0.71 frequency with UPA12 primer. Allele frequencies (AF) also varied slightly among the primers used. UPA02 and UPA 13 had allele frequencies of 8 each while UPA12 had 4 allele frequencies (Table 13). Nei’s genetic diversity indices for the primers revealed variations among the different primers. UPA02 and UPA13 Nei’s gene diversity of 0.64 each while primer UPA12 showed gene diversity of 0.28. Results of polymorphic information content showed that primers UPA02 and UPA13 discriminately revealed a PIC of 0.68 while UPA12 discriminated 0.28 PIC. This study therefore, revealed a critical need for targeting health campaign towards school age children and heads of households in order to empower them with the basic knowledge to recognize, treat and manage their health challenges.Applications of one to two doses of praziquantel considerably reduced the severity of urinary Schistosomiasis in the study area.
The Effect of Fasting Ramadan on Diabetic Patients with High Risk of Cardiovascular Disease

One of the common questions for patients with a history of cardiovascular disease is whether it is safe for them to fast during Ramadan. Yet, studies on the effects of Ramadan fasting on blood lipids, blood pressure, anthropometric parameters and other cardiovascular risk factors are scarce, and have given inconclusive results. The aim of this study is to investigate the effect of Ramadan fasting on cardiovascular risk factors including biochemical indices, blood pressure and main anthropometric parameters. This Prospective observational study was conducted at the CCU (Coronary care unit) and medical wards of Madinat Zayed hospital one of Al Dhafra hospitals, under Seha Abu Dhabi. Fifty-Six diabetic patients admitted with cardiovascular events including 48 males and 8 females with a previous history of cardiovascular event completed the study. Their age ranged between 32 and 91 years with a mean of 54.0 ± 10 years. A non-significant slight biochemical modification with regard to the metabolic profile pre, during and post-Ramadan period was reported: eGFR, total cholesterol, LDL, and HDL were increased yet, triglycerides and creatinine were non-significantly lower during Ramadan. Findings also showed a non-significant decrease in the post Ramadan blood pressure values which could be attributed to the metabolic switch.
Development of MolBEST (STEM-Based Mobile Learning) on Elasticity Materials

Several researchers have researched mobile learning development, but it is different from MolBEST (STEM-Based Mobile Learning). This is because MolBEST developed has features that can train scientific literacy and 21st-century skills that integrate science, technology, engineering, and mathematics. This research aims to develop a mobile learning form of MolBEST and to describe the feasibility (validity, effectiveness, and practicality) of mobile learning. This study uses a developmental design of the Hannafin & Peck model using material and media validation instruments, pretest posttest, and assisted learning implementation observation sheets MolBEST. Based on the analysis of research data, the percentage of MolBEST on the elasticity material from two expert lecturers is classified as very valid with a percentage of 95%. As for the effectiveness, there was an increase in students' scientific literacy skills with an N-gain of 0.64 having moderate criteria and 91% of student responses having very good criteria. The level of practicality in learning is 84% and is categorized as very good. Referring to the results of the validity, effectiveness, and practicality of using MolBEST in learning, it can be concluded that MolBEST is suitable for physics learning. Mobile learning helps increase motivation to learn, understand the material and learn independently easily anywhere and anytime.

Causality Tests and Their Applications to China’s Stock and Housing Markets

The link between the stock market and the housing market is well known to be sensitive. At present, the possibility of a connection between them remains intriguing. Therefore, China works as a case study for the research inquiry into the causal relationship between the stock market and the housing market. Using the monthly data from January 2000 to January 2021 and employing the cross-correlation function approach to perform empirical analysis, the results indicate that the bidirectional causal relationship between the stock market and the housing market has been recognized as one of the most interesting findings, which constitutes a significant departure from previous research. Moreover, the other interesting result is that, from the housing market to the stock market, a causality-in-mean and a causality-in-variance are discovered. Only a tiny number of previous studies have addressed this achievement in the context of China. Meanwhile, this article’s findings have both theoretical and practical implications for China’s proposition.
On the convergence of arithmetic orbifolds

We discuss the geometry of some arithmetic orbifolds locally isometric to a product of real hyperbolic spaces of dimension two and three, and prove that certain sequences of non-uniform orbifolds are convergent to this space in a geometric ("Benjamini--Schramm") sense for hyperbolic three--space and a product of hyperbolic planes. We also deal with arbitrary sequences of maximal arithmetic three--dimensional hyperbolic lattices defined over a quadratic or cubic field. A motivating application is the study of Betti numbers of Bianchi groups.
Matching next-to-leading-order QCD calculations with shower Monte Carlo Simulations: single vector boson and higgs boson productions in powheg

Negli scorsi anni, i calcoli next-to-leading order (NLO) in QCD sono diventati strumenti usuali per studi fenomenologici, sia nell’ambito di collisori leptonici che adronici. Dal punto di vista sperimentale, invece, i programmi Shower Monte Carlo (SMC) sono stati lo strumento principale utilizzato nelle analisi. Questi programmi operano una risommazione dei contributi logaritmicamente dominanti a tutti gli ordini, nell’approssimazione soffice o collineare. L’intero processo e’ quindi da essi rappresentato come una “parton shower”, cioe’ una sequenza di successive emissioni, fortemente ordinate. Fornendo essi risultati pienamente esclusivi, e’ facile interfacciarli con modelli fenomenologici di adronizzazione, permettendo il confronto tra le predizioni teoriche e i dati sperimentali. Tuttavia, questi programmi non raggiungono l’accuratezza dei calcoli NLO.

Fisetin Modulates Toll-Like Receptor-Mediated Innate Antiviral Response in Chikungunya Virus-Infected Hepatocellular Carcinoma Huh7 Cells

In the chronic phase of chikungunya virus (CHIKV) infection, excessive inflammation manifests as incapacitating joint pain and prolonged arthritis. Arthritis resulted from a large influx of infiltrating immune cells driven by pro-inflammatory cytokines and chemokines originating from the toll-like receptor (TLR)-mediated innate antiviral response. This study investigated fisetin’s ability to modulate TLR-mediated antiviral responses against CHIKV in Huh7 cells. The CHIKV inhibitory potential of fisetin was assessed by plaque-forming unit assay, virus yield reduction assay, and bright-field microscopy (cytopathic effect, immunofluorescence). Fisetin’s modulatory potential on TLR-mediated antiviral response was evaluated by immunofluorescence assay (expression of TLR proteins), qRT-PCR (mRNA level of antiviral genes), human cytokine array, and the immunoblotting of key transcription factors. The present study showed fisetin induced the expression of the antiviral genes at an early time-point by promoting the phosphorylation of IRF3 and IRF7. Fisetin reduced excessive inflammatory cytokine responses in CHIKV-infected Huh7 cells by impeding the over-phosphorylation of NF-κB. Fisetin also reduced CHIKV-induced cytopathic effects in CHIKV-infected Huh7 cells. Altogether, our study suggests that fisetin modulates TLR-mediated antiviral responses by affecting the CHIKV-induced inflammatory responses.
