Coronal extension of flaring region magnetic fields inferred from high-resolution microwave and type III burst observations

Observations of three solar radio bursts, obtained with the Very Large Array of the National Radio Astronomy Observatory at 6 cm wavelength, have been combined with meter observations from the Mark III Nancay Radioheliograph. There is a good correlation between solar activity observed at the two wavelength domains. A small change by about 10 sec in the centimetric burst location corresponds to a large change, by about 0.5 solar radius, in the related metric type III burst location. This indicates discrete injection/acceleration regions and the presence of very divergent magnetic fields. The bursts come from two distinct active regions. With two-dimensional spatial resolution, it is shown that, in this sample, each active region possesses a coronal extension that is separated from that of the neighboring active region.
Paracoccidioides restrepiensis has undergone a severe population bottleneck

Genus Paracoccidioides now encompasses five species, P. lutzii, P. brasiliensis sensu stricto, P. americana, P. venezuelensis, and P. restrepiensis. All the paracoccidioidomycosis (PCM) cases reported in Colombia have been classified as P. restrepiensis, which was named in honor of Angela Restrepo, a leading researcher in the field of the biology of the fungus. Previous assessments of genetic diversity have suggested that Paracoccidioides species have differences in their level of polymorphism. To infer changes in effective population size, we used the Pairwise sequentially Markovian coalescent (PSMC) by generating two pseudodiploids for P. restrepiensis and one for P. brasiliensis sensu stricto. We found that P. restrepiensis diverged from its sister species recently, the divergence time from P. venezuelensis being 125,000 (± 42,000) years. The analyses using PSMC show a systematic reduction in the effective population size of P. restrepiensis with a rapid decrease in genetic variability compared to P. brasiliensis sensu stricto, which indicates that P. restrepiensis has undergone a systematic population bottleneck. None of the other two species show the dramatic effective population size reduction observed in P. restrepiensis. These comparisons suggest that the trajectory of P. restrepiensis is somehow different from the other Paracoccidioides species and poses the question regarding the biogeographic events that have led to such a dramatic population pattern.
Exploring the triadic parent–child–sibling relationship: How do mothers’ view of their children impact sibling relationships?

The functioning of the sibling subsystem is often overlooked in research on attachment relationships, despite its both threatening and protective potential. Taking a multi-case approach, this study sought to build theory regarding how the mother–child relationship and the mother’s view of each of her children impact the sibling relationship. Three families were assessed using the Meaning of the Child Interview, a method of analysing parental discourse in a semi-structured interview to understand the parent–child relationship, and a sibling free-play procedure. The study illustrated how in more struggling relationships, the child represented a particular threat or challenge to the mother, and how the child’s accommodation to this influenced the dynamics of the sibling relationship. The sibling may be recruited to care for their sibling to ease demands on their mother, serve as an ally with their mother against their sibling, or siblings may support each other to compensate for what is lacking in the child–parent relationship. This was further influenced by wider systemic challenges to both children and mother, such as parental conflict or settling in a new country.
Optimal Drop Height in Prepubertal Boys Is Revealed by the Performance in Squat Jump

Drop jump (DJ) performance gain with increasing drop height is well documented in adults, but there is still no clear evidence of such gain in children. This study aimed to examine the differences in DJ performance gain in male adults and prepubescent boys by comparing drop heights tailored to each individual’s performance and expressed as a percentage of their squat jump (SJ) performance. Fifteen boys (9–11 y) and 15 men (19–27 y) executed DJs from drop heights that were set at 75%, 100%, 125%, and 150% of their best performance in SJ (DJ75, DJ100, DJ125, and DJ150, respectively). Vertical ground reaction force (vGRF), contact time and kinematics of the lower extremities were captured. The results showed that boys jumped significantly lower than adults in DJs, and both age groups presented jumping gain with increasing drop height, up to DJ125. Boys demonstrated longer total contact time, lower angular velocity and vGRF during the propulsive phase, as well as smaller knee flexion at touchdown and lower reactive strength index. vGRF in DJ75 and DJ100 was lower than in DJ125 and DJ150. The highest value for maximum knee flexion was also presented at DJ150. It is concluded that in prepubescent boys, the appropriate drop height for an effective DJ is linked to their performance in SJ and might be between 75% and 125% of their maximum SJ performance.
The effect of different doses of vitamin D on the prognosis of patients undergoing carpal tunnel syndrome surgery

ABSTRACT Background and Objective: Vitamin D accelerates myelin repair and recovery after nerve damage. This study aimed to evaluate the effect of vitamin D on the prognosis of patients with carpal tunnel syndrome (CTS). Methods: A randomized clinical trial was conducted in the orthopedic ward of Golestan and Imam Khomeini hospitals in Ahvaz for 2 years (from October 2018 to October 2020). Patients were divided into three groups: the first group received 1,000 units of vitamin D daily, the second group received 4,000 units of vitamin D per week for the first 4–6 weeks and then 2,000 units per month, and the third group received no vitamin D supplementation. The results were compared before and after 6 months between the study groups. Results: A total of 105 patients were included in the study, who were divided into three groups. The mean age of the patients was 39.24 ± 7.01 years (25–52 years). The mean level of the vitamin D in the control group was 25.40 ± 8.37 ng/mL, the group receiving 1,000 units/day was 26.71 ± 8.70 ng/mL, and the group receiving 50,000 units per week was 26.17 ± 8.63 ng/mL. The mean values of preoperative pain intensity, symptom severity, and functional status were almost the same in the three groups. These values were reduced after surgery in the two groups receiving the drug compared to the control group. Conclusions: The findings of the study showed that the administration of vitamin D supplementation in patients with CTS can significantly improve the postoperative symptoms of patients who underwent tendon release surgery and further improve the severity of symptoms and dysfunction of patients.
Intuitive risk perception, anxiety and worry during the COVID-19 outbreak in Mexico

Preventive behavior and decision-making processes depend greatly on risk perception. Incorporating the affective component in risk assessment provides valuable information for understanding COVID-19-related risk. The study aimed to adapt and validate the COVID-19 Risk Belief Scale and evaluating Intuitive Risk Perception and its association with anxiety and worry. A cross-sectional study was conducted analyzing data from 694 Mexican adults, which was collected through on-line platforms during 2020. The final CFA including 18 items showed adequate goodness-of-fit indices (RMSEA = 0.059, 90% CI [0.053, 0.065]; CFI = 0.95; TLI = 0.94; SRMR = 0.044) supporting a five-factor structure. Moderate levels of intuitive risk perception were found, as well as moderate to low levels of worry and somatic anxiety. Significant correlations between both measures and risk perception were observed. This study confirms the importance of the affective component within risk assessment and findings become highly significant considering the current worldwide pandemic conditions.
Experiences of Caring for Adolescents Living with HIV (ALHIV): A Qualitative Interview with Caregivers

Purpose This study aims at exploring experiences of people caring for adolescents living with HIV, also known as caregivers. By 2021, 150,000 adolescents were living with HIV and 32,000 adolescents were dying of AIDS related causes. HIV/AIDS remains one of the most serious public health problems, especially among the adolescents. This has placed a heavy burden on many caregivers, yet they are essential in caring for ALHIV. However, focus of all interventions has excluded caregivers of ALHIV. Thus, this is the reason why this study is being conducted to find out caregivers’ experience in caring for ALHIV. Participants and Methods A phenomenological study was carried out. Purposive sampling was used to select a total of 15 caregivers to participate in the study. These participants were subjected to in-depth semi-structured interviews. Their responses were recorded, transcribed and translated for thematic analysis. Results While analyzing the results, six themes emerged. They include: diagnosis and reaction to diagnosis, experiences on adolescent’s HIV serostatus disclosure, stigma and discrimination, care disengagement, and lastly, challenges during care and coping strategies. Caregivers experienced feelings of fear, Guilt, suicidal thoughts after diagnosis. Stigma and discrimination of adolescents living with HIV which was common at school and from the neighbors and the adolescent stage were some of the challenges experienced by the caregivers and it makes it hard to retain ALHIV in care. Conclusion Families are the main source of caregiving to the adolescents living with HIV (ALHIV). The study’s findings indicate that caregivers in the families experience challenges related to family needs, and psychological challenges resulting from the adolescence stage. So, families should not be left to shoulder the burden of caring for ALHIV. As a way forward, social network and financial support should also be strengthened for most caregivers as a coping strategy.
Molecular dynamics studies of CED‐4/CED‐9/EGL‐1 ternary complex reveal CED‐4 release mechanism in the linear apoptotic pathway of Caenorhabditis elegans

Many steps in programmed cell death are evolutionarily conserved across different species. The Caenorhabditis elegans proteins CED‐9, CED‐4 and EGL‐1 involved in apoptosis are respectively homologous to anti‐apoptotic Bcl‐2 proteins, Apaf‐1 and the “BH3‐only” pro‐apototic proteins in mammals. In the linear apoptotic pathway of C. elegans, EGL‐1 binding to CED‐9 leads to the release of CED‐4 from CED‐9/CED‐4 complex. The molecular events leading to this process are not clearly elucidated. While the structures of CED‐9 apo, CED‐9/EGL‐1 and CED‐9/CED‐4 complexes are known, the CED‐9/CED‐4/EGL‐1 ternary complex structure is not yet determined. In this work, we modeled this ternary complex and performed molecular dynamics simulations of six different systems involving CED‐9. CED‐9 displays differential dynamics depending upon whether it is bound to CED‐4 and/or EGL‐1. CED‐4 exists as an asymmetric dimer (CED4a and CED4b) in CED‐9/CED‐4 complex. CED‐4a exhibits higher conformational flexibility when simulated without CED‐4b. Principal Component Analysis revealed that the direction of CED‐4a's winged‐helix domain motion differs in the ternary complex. Upon EGL‐1 binding, majority of non‐covalent interactions involving CARD domain in the CED‐4a‐CED‐9 interface have weakened and only half of the contacts found in the crystal structure between α/β domain of CED4a and CED‐9 are found to be stable. Additional stable contacts in the ternary complex and differential dynamics indicate that winged‐helix domain may play a key role in CED‐4a's dissociation from CED‐9. This study has provided a molecular level understanding of potential intermediate states that are likely to occur when CED‐4a is released from CED‐9.
Recent Progress on MILES for High Reynolds Number Flows

A promising large-eddy simulation (LES) approach is monotonically integrated LES (MILES) which involves solving the Navier-Stokes equations using high-resolution monotone algorithms. In MILES, the subgrid scale (SGS) flow physics is provided by intrinsic, nonlinear, high-frequency filters built into the discretization and implicit SGS models. Mathematical and physical aspects of implicit SGS modeling using nonlinear flux-limiters are addressed using a formalism based on the modified LES equations approach. Detailed properties of the implicit subgrid model are related to the flux limiter, which in turn depends on the specifics of the numerical scheme; we illustrate how the latter properties can directly affect their potential in the MILES framework. Major unresolved issues relevant to LES of complex practical turbulent flows are discussed in this context, including some aspects of boundary condition modeling and overall computational model validation

Basics on growth orders of polymonogenic functions

In this paper, we introduce generalizations of the classical growth order and the growth type of analytic functions in the context of polymonogenic functions. Polymonogenic functions are null-solutions of higher integer order iterates of a generalized higher dimensional Cauchy–Riemann operator. One of the main goals is to prove generalizations of the famous Lindelöf–Pringsheim theorem linking explicitly these growth orders and growth types with the Taylor series coefficients in the context of this function class.
Three‐dimensional Hall MHD simulation of lunar minimagnetosphere: General characteristics and comparison with Chang'E‐2 observations

Lunar minimagnetosphere formed by the interaction between the solar wind and a local crustal field often has a scale size comparable to the ion inertia length, in which the Hall effect is very important. In this paper, the general characteristics of lunar minimagnetosphere are investigated by three‐dimensional Hall MHD simulations. It is found that the solar wind ions can penetrate across the magnetopause to reduce the density depletion and cause the merging of the shock and magnetopause, but the electrons are still blocked at the boundary. Besides, asymmetric convection occurs, resulting in the magnetic field piles up on one side while the plasma gathers on the other side. The size of the minimagnetosphere is determined by both the solar zenith angle and the magnetosonic Mach number, while the Hall effect is determined by the ratio of the pressure balance distance to the ion inertia length. When the ratio gets small, the shock may disappear. Finally, we present a global Hall MHD simulation for comparison with the observation from Chang'E‐2 satellite on 11 October 2010 and confirm that Chang'E‐2 flew across compression regions of two separate minimagnetospheres.
Theoretical modelling of dipole photoconductive antenna for continuous-wave terahertz emission

Photoconductive antenna as continuous-wave terahertz photomixer has attracted much attention in these years. Its main restriction is the limited terahertz radiant power. In this paper, terahertz emission from dipole photoconductive antenna structures based on the photomixing mechanism has been studied. The terahertz output power is proportional to the radiation resistance of the antenna, the square of dc conductance and that of bias voltage. The photoconductive antenna radiation impedance as a function of frequency has been calculated numerically. And results reveal that the dipole photoconductive antenna design dominates the properties of the radiated output at resonant frequencies below 1THz, while the efficiency at higher frequencies is additionally dependent on the design of the interdigitated fingers, the effect of which is modeled by a lumped capacitance in parallel with the photoconductive area.
Non-circular baroclinic beta-plane modons: constructing stationary solutions

Conditions determining the existence of localized steadily translating two-layer vortices (modons) of arbitrary symmetric form on the $\beta$-plane are considered. A numerical method for direct construction of modon solutions is suggested and its accuracy is analysed in relation to the parameters of the computational procedure and the geometrical and physical parameters of the modon sought. Using this method, several non-circular baroclinic solutions are constructed marked by nonlinearity of the dependence of the potential vorticity (PV) on the streamfunction in the trapped-fluid area of the modon, i.e. where the streamlines are closed. The linearity of this dependence and the circularity of the trapped-fluid area are shown to be equivalent properties of a modon. Special attention is given to elliptical modons – extended both in the direction of the modon propagation and in the orthogonal direction, the baroclinic PV component being assumed continuous. The differences between the two types of elliptical modons are discussed. The simplest vortical couples and shielded modons are considered. In the context of the continuity of the baroclinic PV field, the stability of modons is discussed based on numerical simulations.
Biochemical, histological and ultrastructural studies on the ameliorative effects of chrysin on the hepatotoxicity of clonazepam in developing male albino rats

Chrysin is bioactive flavonoids that has numerous pharmacological activities and known to have hepatoprotective effect. The present study aimed to study the potential ameliorative effects of Chrysin (50 mg/kg b.wt./day) on Clonazepam (2 mg/kg b.wt./day) induced liver toxicity. Animals were divided into 4 groups, ten rats in each. Group 1 (Control group received a vehicle 1% w/v Tween 80), group 2 (received 2 mg/kg b.wt./day Clonazepam (CZP) suspended in 1% w/v Tween 80, group 3, (received 50 mg/kg b.wt./day Chrysin suspended in 1% w/v Tween 80, group 4 (received 2 mg/kg b.wt./day CZP, and Chrysin, 50 mg/kg b.wt./day). All animal groups were treated by oral gavage daily for 6 weeks starting at the first day of the experiment. The results indicated that in contrast to the control group, liver transaminases (ALT and AST), malondialdehide (MDA) and cytochrome P450 (Cyp3A4) were increased after the Clonazepam treatment, while the liver protein and the total antioxidant activity (TAA), glutathione reduced (GSH) contents and glutathione S-transferase (GSTs) activity were decreased. Also, the histological examination demonstrated that liver sections of CZP treated developing rats showed cytoplasmic vacuolation and fatty degeneration of some hepatocytes and their nuclei exhibited pyknosis and karyolysis. In addition to conspicuous distortions in the vasculatures, Kupffer cells proliferation and infiltration of lymphocyte were observed. Electron microscopic investigation of hepatocytes of CZP treated animals' revealed clear changes as mitochondrial dysfunction with loss of their cristae and compressed matrices. Also, dilatation and fragmentation of the rough endoplasmic reticulum into smaller stacks have been observed. On the other hand, marked improvement in the liver tissue against the damage displayed by CZP was recorded in biochemical, histological and ultrastructural screening of the hepatic animal sections treated with CZP+ Chrysin.
