PC index as a proxy of the solar wind energy that entered into the magnetosphere: Development of magnetic substorms

The Polar Cap (PC) index has been approved by the International Association of Geomagnetism and Aeronomy (IAGA XXII Assembly, Merida, Меxico, 2013) as a new index of magnetic activity. The PC index can be considered to be a proxy of the solar wind energy that enters the magnetosphere. This distinguishes PC from AL and Dst indices that are more related to the dissipation of energy through auroral currents or storage of energy in the ring current during magnetic substorms or storms. The association of the PC index with the direct coupling of the solar wind energy into the magnetosphere is based upon analysis of the relationship of PC with parameters in the solar wind, on the one hand, and correlation between the time series of PC and the AL index (substorm development), on the other hand. This paper (the first of a series) provides the results of statistical investigations that demonstrate a strong correlation between the behavior of PC and the development of magnetic substorms. Substorms are classified as isolated and expanded. We found that (1) substorms are preceded by growth in the РС index, (2) sudden substorm expansion onsets are related to “leap” or “reverse” signatures in the PC index which are indicative of a sharp increase in the PC growth rate, (3) substorms start to develop when PC exceeds a threshold level 1.5 ± 0.5 mV/m irrespective of the length of the substorm growth phase, and (4) there is a linear relation between the intensity of substorms and PC for all substorm events.
Factors Related to Nurses’ Professional Autonomy When Caring for Patients with COVID-19 in a University Hospital: A Cross-Sectional Study

Although individual factors play a vital role in determining professional autonomy, their specific impact during the coronavirus disease 2019 (COVID-19) pandemic has not been studied. This study aimed to compare nurses’ professional autonomy when caring for patients with COVID-19 and for other patients and explore factors related to autonomy when caring for these patients. A paper-based questionnaire survey was conducted from June to August 2022 among nurses working at a university hospital in Japan. The survey included demographic factors (10 items, including, age, section, years of nursing experience, position, educational background, ladder level, and having certified nurse specialists or certified nurse qualifications) and individual experience factors (4 items: number of COVID-19 patients experienced, frequency and contents of searching for the latest information about COVID-19, frequency of using scientific sources, and frequency of training/study sessions on COVID-19 attended at the hospital). Additionally, basic knowledge of COVID-19 was evaluated. The scale for nurses’ professional autonomy was developed based on a previous study. A paired t-test and stepwise multiple linear regression were used for the analyses. Overall, 241 nurses participated in the survey. The average length of nursing experience was 10.3 ± 9.2 years. The total scores for nurses’ professional autonomy in all 5 factors 27 items were significantly lower (t = −12.1, p < 0.001 ) when caring for COVID-19 patients than when caring for other patients. Specifically, Factor 1 (Cognition) exhibited the most decreased scores when caring for COVID-19 patients than when caring for other patients. Factor 4 (Abstract judgment) differed the least between caring for COVID-19 and for other patients, but the average score was the lowest. More years of nursing experience (β = 0.208, p = 0.001 ) and a higher number of patients with COVID-19 cared for (β = 0.140, p = 0.026 ) were associated with higher autonomy scores. In conclusion, to enhance professional autonomy during an unprecedented pandemic, nurses must enhance cognition and abstract judgment. In the event of a future pandemic, nurses need to create an environment in which they routinely access and utilize the latest information and scientific evidence to provide high-quality nursing care based on their professional judgment and competence.

A Novel Double Stator Hybrid-Excited Flux Reversal Permanent Magnet Machine With Halbach Arrays for Electric Vehicle Traction Applications

This research paper introduces a novel double-stator (DS) hybrid-excited (HE) flux reversal permanent magnet (FRPM) machine with Halbach PM arrays, specifically designed for electric vehicle (EV) traction applications. The study commences with a detailed description of the operating principle of the proposed machine. The machine design incorporates a comprehensive sensitivity analysis of its structural design variables, followed by a multi-objective optimization utilizing the NSGA-II algorithm. The results clearly show that the proposed DS-HE-FRPM machine outperforms the benchmark in several key aspects while adhering to the same PM volume constraint. It exhibits significantly improved back electromotive force, and substantially lower cogging torque. Notably, when compared to the benchmark, the optimized structure of the DS-HE-FRPM machine highlights a notable 22.4% enhancement in electromagnetic torque, while effectively keeping torque ripple at a low level. The underlying reasons behind these notable improvements of the proposed machine structure are explained in detail, providing a comprehensive understanding of their rationales. These findings suggest that the innovative DS-HE-FRPM machine holds significant torque potential, which could greatly enhance the performance and efficiency of EVs. This represents a highly promising development in the field of traction applications.
Matrix Gla protein polymorphism rs1800802 is associated with atheroma plaque progression and with cardiovascular events in a chronic kidney disease cohort

ABSTRACT Background Chronic kidney disease (CKD) is associated with increased atherosclerotic burden and higher risk for cardiovascular events (CVE). Atherosclerosis has a significant genetic component and, in CKD, it is influenced by mineral metabolism alterations. Therefore, genetic modifications of mineral metabolism–related proteins could affect atherosclerosis in CKD patients. In the present study we investigated the role of single nucleotide polymorphisms (SNPs) of the matrix gamma-carboxy glutamic acid protein (MGP) on atherosclerosis progression and CVE in a CKD cohort. Methods A total of 2187 CKD patients from the Observatorio Nacional de Aterosclerosis en Nefrologia (NEFRONA) study were genotyped for SNPs present in the matrix gamma-carboxy glutamic acid (Gla) protein (MGP) gene. Atheromatosis was detected by vascular ultrasound. Progression of atheromatosis, defined as an increase in territories with plaque, was assessed after 24 months. Patients were followed for 48 months for CVE. Association of SNPs with plaque progression was assessed by logistic regression and their capacity to predict CVE by Cox regression. Results Three SNPs of the MGP gene were analyzed. No association of the rs4236 or the rs1800801 SNPs was detected with any of the outcomes. However, patients homozygotes for the minor allele of the rs1800802 SNP showed higher adjusted risk for plaque progression [odds ratio 2.3 (95% confidence interval 1.06–4.9)] and higher risk of suffering a CVE [hazard ratio 2.16 (95% confidence interval 1.13–4.12)] compared with the rest of genotypes. No association of the SNP with total or dp-ucMGP levels was found in a subsample. Conclusions The rs1800802 polymorphism of MGP is associated with plaque progression and CVE in CKD patients.
The Value Relevance of Accounting and Financial Information in Stock Returns: The Case of Jordanian Commercial Banks

The primary aim of this research is to examine the value relevance of accounting and financial information in explaining stock returns by using panel data for a sample of 13 commercial banks listed in Amman Stock Exchange (ASE), through the period from 2010 to 2018. It uses dividends payout ratio, book value per share and earnings per share as proxies of accounting and financial information. The findings indicate that earnings per share, book value per share, dividends payout ratio and bank size do not influence stock returns. These results are consistent with Black and Scholes (1974) and Fama and French (1992), among others.
Recent advances in primary cilia in bone metabolism

Primary cilia are microtubule-based organelles that are widespread on the cell surface and play a key role in tissue development and homeostasis by sensing and transducing various signaling pathways. The process of intraflagellar transport (IFT), which is propelled by kinesin and dynein motors, plays a crucial role in the formation and functionality of cilia. Abnormalities in the cilia or ciliary transport system often cause a range of clinical conditions collectively known as ciliopathies, which include polydactyly, short ribs, scoliosis, thoracic stenosis and many abnormalities in the bones and cartilage. In this review, we summarize recent findings on the role of primary cilia and ciliary transport systems in bone development, we describe the role of cilia in bone formation, cartilage development and bone resorption, and we summarize advances in the study of primary cilia in fracture healing. In addition, the recent discovery of crosstalk between integrins and primary cilia provides new insights into how primary cilia affect bone.
Eruption of the Eyjafjallajökull Volcano in spring 2010: Multiwavelength Raman lidar measurements of sulphate particles in the lower troposphere

A fraction of the volcanic plume that originated from the Eyjafjallajökull volcanic eruption on Iceland in 2010 reached the southern Iberian Peninsula in May 2010. The plume was monitored and characterized in terms of optical and microphysical properties with a combination of Raman lidar and star‐ and Sun‐photometers. Our observations showed that the plume arriving at the Iberian Peninsula was mainly composed of sulphate and sulphuric‐acid particles. To our knowledge, this is the first study of optical properties and inverted microphysical properties of volcanic sulphate particles in the lower troposphere/boundary layer based on multiwavelength Raman lidar measurements. A remarkable increase in the particle number concentration in the accumulation mode was determined from the inversion of the aerosol optical properties. The large Ångström exponents and low linear particle depolarization ratios (4–7%) indicated the presence of small and spherical particles. The particle effective radii ranged between 0.30 and 0.55 µm. In situ instrumentation confirmed an increase of sulphate particles at ground level during this period.
How self-regulation influences academic achievement and positive youth development: the mediating role of internalizing and externalizing symptoms

ABSTRACT Youths’ development can be positively or negatively impacted by various factors in their internal and external environment. This study investigated the interactive effects of self-regulation and internalizing and externalizing problems on academic achievement (reading and maths) and positive youth development (PYD) across one year. Data were obtained from 390 Icelandic youths (44.75% male) at two time points, in grades 6 (Mage = 11.71) and 7 (Mage = 12.70). Structural equation modelling indicated that self-regulation positively predicted all outcome measures one year later, whereas internalizing and externalizing symptoms negatively predicted PYD and maths. The findings further revealed that internalizing symptoms mediated the effects of self-regulation on maths performance, while externalizing symptoms mediated the effects of self-regulation on PYD. These results suggest that self-regulation not only predicts academic achievement and PYD directly, but may also influence these outcomes indirectly by decreasing internalizing and externalizing symptoms.
Channel network growth and river basin morphology

This work examines the influence of the dynamics of basin evolution on the resulting basin form. To achieve this aim, a numerical modeling approach has been adopted which allows the comparison of various evolutionary dynamics in a controlled environment. Resulting basins are compared with one another and with well-known characteristics of natural basins. First, a relatively broad numerical model is developed which describes erosion as the culmination of discrete events. In this context, the impact of four different descriptions of erosion on the basin form is considered. These variants are shown to have great similarity with other models of erosion and network growth proposed in the literature. Each of these variants is also found to develop differing basin structures. One model variant called Greatest Excess Growth always erodes the point with greatest excess shear stress. Among the variants considered, this one develops the most distinctive and realistic basins. Second, the roles of uplift and critical shear stress are investigated under varying initial conditions. For flat initial conditions, basins with lower uplift rates and larger critical shear stresses are found to exhibit slightly larger exponents in Hack's Law and less variability in their normalized drainage directions. With initial conditions that slope either toward or away from a line of specified outlets, both the network growth and resulting topography depend on whether there is uplift or critical shear. In addition, the basin evolution model has difficulty developing scale invariant networks when the initial slope is oriented away from the outlets. Third, the effect of two different storm durations on basin scaling is investigated. The two cases considered are: instantaneous pulses and prolonged storms. When storms are instantaneous, the duration of the related discharge is controlled by the basin structure, but when storms are prolonged, the duration becomes independent of the basin form. These two cases result in different slope-area relationships if the erosion rate depends nonlinearly on contributing area. Thesis Supervisor: Rafael L. Bras Title: Professor
Environmental changes at the Frasnian–Famennian boundary in Central Morocco (Northern Gondwana): integrated rock-magnetic and geochemical studies

Abstract Rock magnetic (magnetic susceptibility and hysteresis parameters) and geochemical analyses (major and trace elements) were carried out on whole rock samples of two Frasnian–Famennian boundary sections, Anajdam and Bou-Ounebdou in the Central Morocco (Western Meseta). During the Frasnian, the decreasing trend of the magnetic susceptibility signal, mainly carried by low-coercivity magnetite grains, indicates a gradual reduction of detrital influx. This decrease in detrital input parallels a Frasnian long-term sea-level rise. In the Late Frasnian Kellwasser Horizons, that are classically considered to represent highstand deposits, the magnetic signal exhibits the lowest intensities in connection with maximum diamagnetic contribution of the carbonate fraction. With respect to geochemical data, the two black carbonate-rich Kellwasser Horizons are characterized by noticeable positive anomalies of bottom-water dysoxic proxies and of marine primary productivity markers. Our data thus suggest that in Central Morocco, the Late Frasnian marine environments were marked by a relatively important biogenic productivity favouring the onset of oxygen-depleted conditions during periods of maximum transgression on the continental platforms.
A Nutrigenetic Strategy for Reducing Blood Lipids and Low-Grade Inflammation in Adults with Obesity and Overweight

The pathogenesis of obesity and dyslipidemia involves genetic factors, such as polymorphisms related to lipid metabolism alterations predisposing their development. This study aimed to evaluate the effect of a nutrigenetic intervention on the blood lipid levels, body composition, and inflammation markers of adults with obesity and overweight. Eleven genetic variants associated with dyslipidemias in Mexicans were selected, and specific nutrigenetic recommendations for these polymorphisms were found. One hundred and one adults were recruited and assigned to follow either a standard or nutrigenetic diet for eight weeks. Anthropometric, biochemical, body composition, and inflammation markers were evaluated through standardized methods. Weighted genetic risk scores (wGRSs) were computed using the study polymorphisms. After intervention, both diets significantly decreased the anthropometric parameters and body composition (p < 0.05). Only the nutrigenetic diet group showed significant reductions in VLDL-c (p = 0.001), triglycerides (p = 0.002), TG:HDL (p = 0.002), IL-6 (p = 0.002), and TNF-α (p = 0.04). wGRSs had a high impact on the ΔTGs and ΔVLDL-c of both groups (standard diet: ΔTGs: Adj R2 = 0.69, p = 0.03; ΔVLDL-c: Adj R2 = 0.71, p = 0.02; nutrigenetic diet: ΔTGs: Adj R2 = 0.49, p = 0.03 and ΔVLDL-c: R2 = 0.29, p = 0.04). This nutrigenetic intervention improved lipid abnormalities in patients with excessive body weight. Hence, nutrigenetic strategies could be coadjuvant tools and enhance the standard dietary treatment for cardiometabolic diseases.
Experiments on near-field radiative heat transfer: A review

Near-field radiative heat transfer (NFRHT) has been demonstrated to exceed the blackbody limit due to the coupling effect of evanescent waves in the near-field regime, opening the door to application in active thermal control, thermophotovoltaics, and nanoscale imaging. Although the theoretical studies on NFRHT have been investigated exhaustively, the experimental measurement of NFRHT has been stagnant due to the challenges in controlling gap distance at the nanoscale. Remarkable progress has been greatly boosted until the 21st century to overcome the nanoscale controlling and measurement of NFRHT, benefiting from the advances of micro-nanofabrication techniques and materials science. This review examines an in-depth discussion of the experimental development of NFRHT. According to the structure of the emitter and receiver, the experimental devices are divided into three different categories: plate-to-plate structure, tip-to-plate structure, and sphere-to-plate structure. Existing experimental setups and methodology of NFRHT between metals, semiconductors, two-dimensional materials, and hyperbolic metamaterials are thoroughly explored and analyzed in detail. Finally, the remarks on outstanding challenges at the nanoscale and promising advances in applications are briefly concluded in the measurements of NFRHT.
Regional geology and geophysics of the eastern Gulf of Guinea (Niger Delta to Rio Muni)

There are many key aspects to the geology and geophysics of the petroliferous basin systems of the eastern Gulf of Guinea, which extends from the Niger Delta to North Gabon. This article provides a background to the regional geology and focuses on the structural geology and the structural styles associated with the key tectonic episodes responsible for hydrocarbon trapping. This work results from several regional studies carried out by Exploration Consultants, based on public domain seismic and well data combined with the results of new analytical work. The region has been divided into six geotectonic provinces (Figure 1):
Environmentally-Induced Displacement: Theoretical Frameworks and Current Challenges

The aim of the presented paper is to demonstrate environmentally-induced displacement as an increasingly important category of population movement that represents a new set of challenges to the international community and to public international law as well. There are three basic objectives that this work intends to achieve: 1) to argue in favour of distinguishing environmentally-induced displacement from the broader category of migratory movements and thereby making it a fully autonomous concept within the existing taxonomies, 2) to illustrate the diversity and inconsistency of environmentally displaced people (EDPs) theoretical concept, 3) to provide references to earlier theoretical achievements in this particular field of study. For these purposes, the paper tries to capture both the phenomenon of environmental displacement itself, and the problems of people affected by its consequences. Apart from theoretical considerations, it also examines which main factors force people to abandon their homes. Both long-term environmental hazards and short-lived natural disasters are investigated here, and it is shown how they entail significant implications for the dynamics of population mobility.
Modelling electromagnetic properties of saturated sand and clay

Dielectric spectra of sand–water and clay–water mixtures differ in that the real permittivity of sand–water mixtures is almost constant over the 1 MHz to 1 GHz frequency range while the real permittivity of clay–water mixtures decreases with increasing frequency, a phenomenon termed the dielectric dispersion. A theoretical model is established for clay minerals so that the mechanisms controlling dielectric dispersion can be analysed and the dielectric dispersion magnitude can be quantified. Interfacial polarisation is the most important mechanism accounting for dielectric dispersion. Bound water polarisation also contributes to dielectric dispersion but its influence is small. The magnitudes of the contributions of these two polarisation mechanisms to the total dielectric dispersion magnitude are primarily determined by the total specific surface area. The model is successfully applied for dielectric spectrum analyses of saturated Ca-bentonite, Na-bentonite and kaolinite.
International Student Profiling Framework

The current conventional way of screening international students, solely based on prior admission and self-reported documents, is inadequate. Given the drastic increase in the number of incoming students, this inadequacy calls for better security surveillance. Therefore, this study investigates how personality traits can influence one’s online prosocial behavior, as an alternative screening mechanism for international students. To assess the association between Big Five and Dark Triad personality traits and online prosocial behavior via the mediation of self-esteem, cross-sectional survey data was collected from 218 international postgraduate students and analyzed using partial least squares structural equation modeling. The significant outcome of this study is the establishment of the International Student Profiling Framework, which serves as the basis for understanding the influence of personality traits and self-esteem on international students’ online prosocial behavior.
