AbstractStatins are cholesterol-lowering drugs commonly used among people with HIV, associated with an increased risk of myopathies. Considering that cardiovascular disease, statin therapy, and sarcopenia are independently prevalent in people with HIV, clarity on the potential benefits or harms of statin therapy on muscle health is useful to provide insight into ways to maximize skeletal muscle health and minimize CVD risk in this population. We aimed to study the effects of statin therapy on strength, muscle mass, and physical function parameters in people with HIV. This was a pilot cross-sectional study. People with HIV on continuous statin therapy (n = 52) were paired 1:1 according to age (people with HIV 53.9 ± 8.2 and people with HIV on statins 53.9 ± 8.4 years), sex, body mass index (Body mass index, people with HIV 28.6 ± 5.3 and people with HIV on statins 28.8 ± 6.3 kg/m2), and race with people with HIV not using statin (n = 52). Participants were evaluated for muscle strength (i.e. handgrip strength), lean and fat body mass (using bioelectric impedance analysis), and physical function (i.e. Short Physical Performance Battery—SPPB). Isokinetic strength and appendicular lean mass (using dual-energy X-ray absorptiometry), more accurate strength and body composition measures, were determined in 38% of the participants. Overall, statin usage does not exacerbated loss of muscle strength (32.2 ± 11.5 vs. 30.3 ± 9.6 kg, p > 0.05) muscle mass (7.6 ± 1.8 vs. 7.7 ± 1.1 kg/m2, p > 0.05), and impaired physical performance (10.1 ± 1.8 vs. 9.7 ± 2.1 points, p > 0.05) of PLWH. When analyzed by sex, men living with HIV on statins usage presented higher appendicular muscle mass (28.4 ± 3.1 vs. 26.2 ± 4.9 kg, p < 0.05) handgrip strength (42.1 ± 8.8 vs. 37.1 ± 8.3 kg, p < 0.05) and physical function through SPPB score (10.9 ± 1.3 vs. 9.5 ± 2.1, p < 0.05) than men living with HIV not on statins treatment. The same protection was not observed in women. This data was demonstrated when muscle mass and strength were determined clinically (i.e. handgrip strength and electrical impedance) and when more precise laboratory measurements of muscle mass and strength were conducted (i.e. isokinetic strength and DXA scans). Statin does not exacerbate muscle wasting, strength loss, or muscle dysfunction among people with HIV. Indeed, statins may protect men, but not woman with HIV against HIV and antiretroviral therapy-induced loss of muscle mass and strength.

AbstractIn this study, an experimental study based on the target visibility criteria is carried out for dark and foggy environments, where only vehicle headlights are active. More specifically, the performances of the headlights containing halogen, xenon, and LED light sources in dark and foggy weather conditions are examined and the performance of each headlight is evaluated separately. According to the general result of the visibility experiments, the participants perceived the target object in a shorter time when halogen headlights are used. It is also observed that the average target perceived times of the participant under foggy conditions are at different levels depending on the type of headlights with different correlated color temperature (CCT) and color rendering (CRI) indexes. According to the experimental results performed under foggy conditions, the target detection times of the participants are the shortest at the halogen headlight, the second at the xenon headlight, and the third under the LED lights. It has also been observed that this sequencing is gender-independent. However, the ratio of the detection time of female participants to that of male participants varies between 1.72 and 3.65 times. In other words, female participants perceive the targets in a much longer period than male participants.
Inequality in time to first antenatal care visits and its predictors among pregnant women in India: an evidence from national family health survey
Authors: Tripathy Abhipsa , Mishra Prem Shankar 
Published: March 2023

AbstractFor countries with high maternal mortality and morbidity, on-time initiation of antenatal care (ANC) is indispensable. Therefore this paper aims for studying the median survival time (MST) of first ANC among pregnant women as well as understanding the contextual factors that influence a mother’s decision to access ANC services in India. The study used cross-sectional survey data obtained from the NFHS-4 conducted in 2015–2016. The MST of the timing of the first ANC visit was estimated using the Kaplan-Meir estimate. A multivariate Cox-proportional hazard regression model was used to identify the factors related to the timing of the first ANC visit with a 95% confidence interval (CI). Overall at least one ANC checkup was assessed by 60.15% of women and the median survival time for the first ANC checkup was found to be 4 months. Early initiation of ANC in pregnant women increased by 37% (AHR: 1.37, CI:1.34–1.39) for primary education, and 88% (AHR:1.88, CI:1.86–1.90) for secondary education compared to women having no formal education. Results of the current study revealed that the median survival time of the first ANC visit was 4 months in India which is delayed compared to recommendations of WHO. Therefore boosting the access and utilization of antenatal care coverage among pregnant women can ensure the best health outcomes for their pregnancy.

AbstractThe physicochemical properties of groundwater, geochemical characteristics and subsurface formation of the Oke-Tage waste dumpsite soil material were assessed to determine the impact of the leachate generated from the waste dumpsite on the quality of the groundwater within the study area. Water samples collected from hand-dug wells were analyzed to determine groundwater quality, while soil samples were examined for their geochemical characteristics. Ten Vertical Electrical Sounding (VES) surveys were carried out with an electrode spacing (AB/2) increasing from 1 to 200 m. Also, four 2D electrical resistivity profilings were done using the dipole–dipole configuration. The hydro-chemical analysis showed an elevated Cadmium (Cd) and Lead (Pb) concentration above the maximum permissible limits. The physicochemical results indicated that the Electrical Conductivity (EC) ranged from 1900 to 3670 µS/m, while Total Dissolved Solid (TDS) ranged from 585 to 620 mg/L. The health risk assessment showed no significant health risks associated with exposure to the metals due to HI values less than 1. Based on the VES result, four geoelectric layers comprising topsoil, weathered layer, fractured basement, and fresh basement were identified. The 2D resistivity structures revealed that the topsoil and weathered layers practically merged and are characterized by relatively low resistivity (< 30 Ωm) beneath the dump site. The study concluded that the groundwater and soil in the vicinity of the investigated Oke-Tage waste dumpsite had been negatively impacted to levels that called for caution especially using the water for regular potability purposes.

Published: March 2023

AbstractSperm competition is a powerful force driving the evolution of ejaculate and sperm traits. However, the outcome of sperm competition depends on many traits that extend beyond ejaculate quality. Here, we study male North African houbara bustards (Chlamydotis undulata undulata) competing for egg fertilization, after artificial insemination, with the aim to rank the importance of 14 parameters as drivers of siring success. Using a machine learning approach, we show that traits independent of male quality (i.e., insemination order, delay between insemination and egg laying) are the most important predictors of siring success. Traits describing intrinsic male quality (i.e., number of sperm in the ejaculate, mass motility index) are also positively associated with siring success, but their contribution to explaining the outcome of sperm competition is much lower than for insemination order. Overall, this analysis shows that males mating at the last position in the mating sequence have the best chance to win the competition for egg fertilization. This raises the question of the importance of female behavior as determinant of mating order.
Gathering Perspectives on Video- and App-Based Language Instruction: A Technology-Based Coaching Intervention to Increase Spanish-Speaking Latino Caregivers' Use of Naturalistic Language Intervention Strategies
Authors: Larson Anne L. , Caballero Rosario , Snyder Patricia , Griebel Sonja , Valentin Rachelle , Bourret Camille 
Published: March 2023

Purpose:
Few caregiver-implemented naturalistic language interventions (NLIs) are available for Spanish-speaking Latinos who have young children under 3 years with language delays, and there is a scarcity of studies that provide information about intervention development or social validity of interventions for this group. This study introduces Video- and App-Based Language Instruction (VALI) as a technology-based caregiver-coaching intervention being developed to increase caregivers' use of Spanish language-promoting strategies in everyday activities with their infants and toddlers.

Method:
Fifteen participants including caregivers, speech-language pathologists, and researchers completed an online survey and participated in focus groups to share their perspectives on the feasibility, acceptability, and usefulness of the first iteration of VALI. Data were summarized with descriptive statistics and thematic analysis.

Results:
Participants generally provided support for VALI and thought caregivers could use the technology-based intervention within naturalistic interactions. VALI materials received positive ratings for appearance, inclusivity, and understandability. Specific suggestions were provided for semantic and syntactic adjustments. Participants shared comments to improve individual VALI strategies and help ensure the asynchronous coaching procedures and targeted outcomes were culturally acceptable.

Conclusions:
The first iteration of VALI appears to be a promising NLI for use by Spanish-speaking Latino caregivers with their young children. After initial adaptations are made based on findings from this study, additional feasibility and efficacy evaluations should be conducted. Recommendations for further development of VALI have implications for application in similar interventions for Spanish-speaking Latino caregivers.

VT‐NeRF: Neural radiance field with a vertex‐texture latent code for high‐fidelity dynamic human‐body rendering
Authors: Hao Fengyu , Shang Xinna , Li Wenfa , Zhang Liping , Lu Baoli 
Published: March 2023

AbstractThe fusion of a human prior with neural rendering techniques has recently emerged as one of the most promising approaches to processing dynamic human‐body scenes with sparse inputs. However, learning geometric details and appearance in dynamic human‐body scenes based solely on a human prior model represents a severely under‐constrained problem. A new human‐body representation method to solve this problem: a neural radiance field with vertex‐texture latent codes (VT‐NeRF) is proposed. VT‐NeRF uses joint latent code to improve access to detailed information, combining vertex latent codes with 2D texture latent codes for the body surface. Referencing a 3D human skeleton for accurate guidance, the human model can quickly match poses and learn information about the body in different frames. VT‐NeRF can integrate body information from different frames and different poses quickly because it uses an information‐rich human prior: a 3D human skeleton and parametric models. A 3D human scene is then presented as an implied field of density and colour. Experiments with the ZJU‐MoCap dataset show that our method outperforms previous methods in terms of both novel‐view synthesis and 3D human reconstruction quality. It is twice as fast as Neural Body, and its average accuracy reaches 95.9%.
An improved time‐domain analytical method for LLC resonant converters and dead time designs for zero‐voltage switching
Authors: Jiao Jian , Guo Xizheng , Wang Chenchen , You Xiaojie , Li Kai 
Published: March 2023

AbstractIn this paper, an improved time‐domain analytical method for LLC resonant converters is proposed. Unlike traditional time‐domain analytical methods, the resonant current in the dead time is derived by considering the equivalent capacitances of the switching devices and the transformer. The equivalent output capacitance of the primary‐side switch is calculated by using a two‐segment fitting approach. The equivalent capacitance of the transformer is calculated by using the six‐capacitor model. The current increment method is used to calculate the initial value of the magnetizing current and to determine the numerical calculation conditions for the proposed time‐domain expressions. Finally, the dead time ranges for zero‐voltage switching of the converter are derived based on the improved time‐domain method. Experiments were carried out with a 10 kW LLC resonant converter. The lower limit of the dead time calculated with the proposed method is closer to the experimental results than the values of two conventional methods.

Context.GaiaData Release 3 (GaiaDR3) time series data may contain spurious signals related to the time-dependent scan angle.Aims.We aim to explain the origin of scan-angle-dependent signals and how they can lead to spurious periods, provide statistics to identify them in the data, and suggest how to deal with them inGaiaDR3 data and in future releases.Methods.Using realGaia(DR3) data alongside numerical and analytical models, we visualise and explain the features observed in the data.Results.We demonstrated withGaia(DR3) data that source structure (multiplicity or extendedness) or pollution from close-by bright objects can cause biases in the image parameter determination from which photometric, astrometric, and (indirectly) radial velocity time series are derived. These biases are a function of the time-dependent scan direction of the instrument and thus can introduce scan-angle-dependent signals, which due to the scanning-law-induced sampling ofGaiacan result in specific spurious periodic signals. Numerical simulations in which a period search is performed onGaiatime series with a scan-angle-dependent signal qualitatively reproduce the general structure observed in the spurious period distribution of photometry and astrometry, and the associated spatial distributions on the sky. A variety of statistics allows for the deeper understanding and identification of affected sources.Conclusions.The origin of the scan-angle-dependent signals and subsequent spurious periods is well understood and is mostly caused by fixed-orientation optical pairs with a separation < 0.5″ (including binaries withP ≫ 5 y) and (cores of) distant galaxies. Although most of the sources with affected derived parameters have been filtered out from theGaiaarchivenss_two_body_orbitand severalvari-tables,GaiaDR3 data remain that should be treated with care (no sources were filtered fromgaia_source). Finally, the various statistics discussed in the paper can be used to identify and filter affected sources and also reveal new information about them that is not available through other means, especially in terms of binarity on sub-arcsecond scale.

AbstractTransition-metal-nanoparticles-catalyzed C–H activation/functionalization is a prominent topic in contemporary research, enabling the functionalization of privileged heterocyclic scaffolds that hold a significant space in the scientific community due to their immense applications in materials science and in medicinal, natural product, and agricultural chemistry. Among transition-metal-based nanoparticles, Pd nanoparticle catalysis has emerged as the most attractive tool for promoting a wide array of practical synthetic transformations of heterocycles. In the last few years, the catalytic application of Pd nanoparticles in C–H functionalization has gained popularity in generating relatively inaccessible bonds with a high degree of selectivity and efficiency via the activation of surface metal atoms at the nanoscale level. The quantum size effect of nanoparticles offers a large surface area, with typically many easily accessible active sites/unit areas. These unique characteristics of nanoparticles are considered primary factors of enhanced catalytic activity compared to bulk materials. The nanoparticle catalysts anchored on solid-supports plus unsupported types (e.g., magnetic nanoparticles) allow easy separation from the reaction mixture, enabling recycling multiple times, which contributes notably to sustainable management and cost efficiency of a production process. In the current review, we discuss Pd-nanoparticles-catalyzed C(sp2)–H arylation for the synthesis of functionalized heterocycles, covering literature reports from 2010 to 2021. The preparation of Pd nanoparticles and the mechanistic realizations in their corresponding reactions are also explained briefly.1	Introduction2	Arylation of Heterocyclic Scaffolds2.1	Synthesis of Functionalized Indole Derivatives2.2	Synthesis of Functionalized (Benzo)thiazole/Benzoxazole Derivatives2.3	Synthesis of Functionalized Triazoles2.4	Synthesis of Functionalized Pyridines and Related Scaffolds2.5	Synthesis of Functionalized Furan, Thiophene and N-Methylpyrrole Scaffolds2.6	Synthesis of Functionalized Multiple Heterocycles via Single-Step Strategies3	Conclusions

Strategies for multiple-level parallelizations of quantum-mechanical calculations are discussed, with an emphasis on using groups of workers for performing parallel tasks. These parallel programming models can be used for a variety ab initio quantum chemistry approaches, including the fragment molecular orbital method and replica-exchange molecular dynamics. Strategies for efficient load balancing on problems of increasing granularity are introduced and discussed. A four-level parallelization is developed based on a multi-level hierarchical grouping, and a high parallel efficiency is achieved on the Theta supercomputer using 131 072 OpenMP threads.
Under-threshold RABBITT in argon
Authors: Kheifets Anatoli S 
Published: March 2023

Abstract
The process of reconstruction of attosecond bursts by beating of two-photon transitions (RABBITT) can involve a transition from under the ionization threshold. Such an under-threshold RABBITT (or uRABBITT) was demonstrated experimentally and analyzed theoretically in He and Ne. In the present work, we explore an analogous process in the argon atom. The uRABBITT in Ar reveals the familiar physical effects: a phase transition across the threshold and the symmetry modification of the photoelectron momentum distribution. It can also be used for mapping the electronic structure of the target atom bound states.

AbstractVarious aspects of phonon spectrum changes in nanostructured phonon-mediated superconductors are considered. It is shown how, with the development of experimental techniques and, accordingly, obtaining new results, the understanding of the influence of the surface and nanoscale on the magnitude of the electron–phonon interaction and the critical temperatureTcchanged and deepened. The review is organized as follows. After theIntroduction, in thesecondpart we give the quick theoretical background for the description of superconductivity within the framework of various formalisms. In thethirdpart we describe the properties of nanostructured (granular) thin films paying attention to the impact of grain sizes and methods of deposition on theTcvalue. The role of material parameters is underlined and different aspects of the behavior of granular thin films are discussed. In thefourthsection the impact of external sources of modification of the phonon spectra like noble gases and organic molecules are considered. Problems and progress in this area are discussed. Thefifthpart is dedicated to the phonon modification and related quantum size effects in nanostructured superconductors. In thesixthpart we review the results of direct evidence of phonon softening in nanostructured superconductors and in theseventhsection we discuss a possible alternative description of the superconducting properties of nanostructured superconductors related to the concept of metamaterials. In theeighthandninthparts we review the impact of substrates with lattice mismatched parameters and graphene sheets, respectively, on the modification of the phonon spectrum and enhancement of superconductivity in various superconducting thin films. Finally, in the lasttenthsection we consider the nonequilibrium superconductivity driven by femtosecond pulses of light, which leads to generation of coherent phonons and to a significant increase in the critical temperature in a number of superconducting materials.

Abstract
Plasma equilibrium is critical for experimental operation and data analysis in tokamaks. The number and location of magnetic diagnostics provide the magnetic field and flux information that influences the accuracy of the plasma equilibrium reconstruction. In this research, the truncated singular value decomposition method is applied to minimize the number of magnetic diagnostics for plasma equilibrium reconstruction based on Experimental Advanced Superconducting Tokamak existing magnetic diagnostics system. The reconstructed results with a reduced number of magnetic diagnostics are consistent with results obtained using full magnetic diagnostics by EFIT code. This implies that the approach of minimizing the number of magnetic diagnostics in reconstruction can reduce the demand for magnetic diagnostics while ensuring the accuracy of plasma equilibrium reconstruction with feasibility and reliability. Reduced magnetic diagnostics can increase tolerance for the absence of certain existing magnetic diagnostics and could be a reference for the redundancy design of magnetic diagnostics system in future fusion devices.
