The ERA‐Interim reanalysis: configuration and performance of the data assimilation system

ERA‐Interim is the latest global atmospheric reanalysis produced by the European Centre for Medium‐Range Weather Forecasts (ECMWF). The ERA‐Interim project was conducted in part to prepare for a new atmospheric reanalysis to replace ERA‐40, which will extend back to the early part of the twentieth century. This article describes the forecast model, data assimilation method, and input datasets used to produce ERA‐Interim, and discusses the performance of the system. Special emphasis is placed on various difficulties encountered in the production of ERA‐40, including the representation of the hydrological cycle, the quality of the stratospheric circulation, and the consistency in time of the reanalysed fields. We provide evidence for substantial improvements in each of these aspects. We also identify areas where further work is needed and describe opportunities and objectives for future reanalysis projects at ECMWF. Copyright © 2011 Royal Meteorological Society
Asymptotically perfect wideband focusing of multiring circular arrays

The concept of coherent focusing of sensor arrays, introduced by Wang and Kaveh, led to the development of high-performance and computationally efficient algorithms for wideband direction finding and beamforming. Nonetheless, the quality of focusing depends on the understanding and the proper exploitation of specific array manifold properties. Circular arrays exhibit uniform (isotropic) performance over the entire azimuthal range and allow the use of fast algorithms, originally developed for uniform linear arrays, by decomposing the manifold into circular harmonics. Coherent wideband focusing of circular arrays suffers from ambiguities, noise warping, and numerical ill conditioning. In this work, it is shown that a fast orthonormal beamspace transformation combining the responses of two concentric rings can perfectly focus wideband sources at all azimuth angles in the circular harmonic domain in the limit of infinite number of sensors. The information loss after focusing is minimized through an analytical approach. The proposed focusing scheme is computationally very efficient and can be directly extended to multiring circular arrays that are arranged into a set of nested two-ring subarrays to cover very large bandwidths.
Chronic cold-stress induced histopathological changes, oxidative stress, and alterations in liver functions and nutrient composition of hybrid red tilapia and the potential protection of unsaturated fatty acids

The hybrid red tilapia (♂Oreochromis niloticus × ♀O. mossambicus) is a promising tilapia fish with high growth rate, market acceptability, and the ability to live in a wide range of salinities, but it is sensitive to low water temperature. Therefore, the objective of this experiment was to improve hybrid red tilapia resistance to chronic cold stress by increasing unsaturated fatty acids and evaluating their effects on fish body weight, hepatosomatic index (HSI), body nutrient composition, liver function enzymes, histopathological alterations, and biomarkers of oxidative stress in the gills and liver. For 98 days, fish were fed four diets based on two dietary fat sources: corn oil (a traditional source) and Aquafat-O® (a commercial product rich in high polyunsaturated fatty acids), in different ratios of 3:0 (T0), 2:1 (T1), 1:2 (T2), and 0:3 (T3), respectively. Subsequently, all groups (T0+, T1, T2, and T3) were subjected to water cold stress at 13 °C for 15 days, with half of the control group serving as a negative control (T0-; at a rearing water temperature of 25-26 °C). Chronic old stress caused significant reductions in fish body weight, HSI, aspartate transaminase and alanine transaminase activities, fat and energy contents, and oxidative stress biomarkers in the liver and gills. Red tilapia subjected to low temperatures showed severely altered histopathological conditions in the liver and gills. However, by gradually increasing the Aquafat-O® ratio in the diet, the negative effects of cold stress were mitigated. Thus, it could be concluded that the beneficial use of Aquafat-O® (as a promising fat source) at a percentage of up to 69.60 g kg-1 is necessary to cope with the cold-water stress for sensitive hybrid red tilapia.
Factors associated with women diagnosed with syphilis who received prenatal care in a primary healthcare unit

ABSTRACT Objective To estimate the prevalence of syphilis and its associated factors in women who were treated at public maternity hospitals and received prenatal care in a primary healthcare unit. Methods This cross-sectional study included 399 postpartum women. Interviews were conducted, and additional data were extracted from the pregnant woman’s booklet, medical records, and printed tests. The dependent variable was a gestational syphilis diagnosis. The independent variables were grouped into socioeconomic and demographic, behavioral, reproductive, and prenatal blocks. The prevalence, prevalence ratios, and 95% confidence intervals (95%CI) were calculated. The χ 2 test was also performed (p≤0.05). Multivariate analysis was performed using Poisson regression models. Results The prevalence of gestational syphilis was 9.61% (95%CI: 7.14-12.83). We identified the following determining factors (adjusted prevalence ratios): history of sexually transmitted infections (2.3), first sexual intercourse by the age of 15 (2.42), partner having a history of syphilis (5.98), partner using crack/cocaine (6.42) and marijuana and others (3.02), not having a partner (3.07), low income (2.85), history of stillbirth (5.21), beginning prenatal care in the third trimester (3.15), and prenatal care received in a primary healthcare unit (without a Family Health Strategy team) (0.35). Conclusion Individual and prenatal factors were associated with gestational syphilis. To control congenital syphilis, targeted interventions are needed to control syphilis in the adult population including expansion of access to quality prenatal care with identification of risks for syphilis and connection between prevention and treatment actions, implementation of strategies focused on early sexual education, effective establish prenatal care involving both partners, and effective implementation of the National Men’s Health Policy (PNAISH - Política Nacional de Atenção Integral à Saúde dos Homens ).
Prevalence of Attention Deficit Hyperactivity Disorder Among Children in Makkah Region, Saudi Arabia

Introduction Attention-deficit/hyperactivity disorder (ADHD) is the most common behavioral disorder in children and is described as a disease involving loss of self-control. The core symptoms of ADHD are inattentiveness, impulsivity, and motor unrest. Furthermore, poor concentration, distraction, hyperactivity, and poor academic achievement at school or at home are other symptoms. ADHD, like other prevalent medical disorders such as asthma and schizophrenia, may be impacted by several genes and has multiple contributing causes that are not all related to each other. The management of ADHD contains multimodal treatments, starting with psycho-education for parents and the child or adolescent patient in an age-appropriate manner called cognitive behavioral therapy. The worldwide prevalence rate of ADHD among children is 7.2% and, in some countries, can be higher and reach 15.5%; studies show the average prevalence of ADHD in the Kingdom of Saudi Arabia (KSA) is 9.2%. Method A descriptive cross-sectional study was conducted from December 2022 to January 2023 among children who live in Makkah between the ages of 4 and 14 years old via an online survey that contained the ADHD Rating Scale-IV for parents/teachers, and caregivers based on Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV criteria. The scale was translated into Arabic and contains 18 questions about ADHD symptoms. Result The overall prevalence of combined ADHD among children in Makkah is 52.5% (n=203 out of 387); most of them were males (30.8%) and 21.7% were females (P=0.09), and most of the combined ADHD prevalence was between the ages of 11 and 14 (20.4%), then the age of 4-7 (16.8%), and 15.3% of them were between 8 and 10 years old. Additionally, the results show a higher prevalence of combined ADHD in Makkah city (33.1%) (n=121) in comparison to rural areas 19.4% (n=82) (P=0.132). Conclusion The aim of the study was to measure the prevalence rate of ADHD in the Makkah region. The study showed a high prevalence rate of ADHD (52.5%) among children in Makkah; the study was carried out online using an ADHD scale, and more accurate results could be found by using face-to-face interviews and including both parents and teachers.
Factors Associated with Medication Adherence in Elderly Individuals with Tuberculosis: A Qualitative Study

Methods This qualitative study was conducted in two phases, using an integrative literature review and individual interviews. Studies were gathered without time restriction from MEDLINE databases, Institute for Scientific Information (ISI), Google Scholar, Scopus, and EMBASE, as well as national databases, including Scientific Information Database and Magiran. The findings of 38 studies that met the inclusion criteria were analyzed through the conventional content analysis method based on the ecological approach. After reviewing and forming the data matrix, purposive sampling was performed among healthcare professionals, elderly tuberculosis patients aged 60 and over, and family caregivers of elderly patients to conduct individual interviews. Data obtained from 20 interviews were analyzed using the directed content analysis method. After coding, the data from individual interviews were entered based on similarity and difference in the categories of data matrix obtained from the literature review. Results In general, the aforementioned codes were placed in four main categories, including individual factors (i.e., biological factors, affective-emotional factors, behavioral factors, cognitive factors, tuberculosis-related factors, and economic factors), interpersonal factors (i.e., patient's relationship with treatment team and family-related factors), factors related to healthcare service provider centers (i.e., medical centers' facilities and capacity building in healthcare service provider), and extraorganizational factors (i.e., social factors and health policymaking). Conclusion The results of this study showed that medication adherence in elderly patients with tuberculosis was a complex and multidimensional phenomenon. Therefore, society, policymakers, and healthcare providers should scrutinize the factors affecting medication adherence in this group of patients to plan and implement more effective interventions.
Using Lidar Digital Elevation Models for Reflectometry Land Applications

Lidar elevation maps are utilized in a bistatic electromagnetic scattering model of the Cyclone Global Navigation Satellite System over San Luis Valley in Colorado, USA. The results are compared with the results generated using the Shuttle Radar Topography Mission (SRTM) 1-arcsecond global digital elevation model (DEM). The high-resolution lidar maps are also used to generate maps of surface roughness at length scales finer than the horizontal resolution of SRTM. Model results using these maps illustrate the importance of the spatial variation of surface roughness on reflectometry signals. Results also highlight the shortcomings of using SRTM in scattering models and show improvements when a lidar DEM is used.
The Impact of Altruistic Teaching on English as a Foreign Language (EFL) Learners’ Emotion Regulation: An Intervention Study

The second language acquisition (SLA) field has recently seen heightened interest in the study and application of positive psychology (PP). Emotion regulation is one of the concepts that has been stressed in PP. Several studies in PP have delved into how controlling one’s emotions improves second language learning/teaching. One of the concepts that has slipped the minds of researchers in the field is altruistic teaching. Unlike egocentric acts, altruistic teaching acts are performed to improve others’ well-being. Despite their importance in causing positive emotional effects, no study has investigated the impact of altruistic teaching acts on learners’ emotion regulation. To bridge this gap, the present study sought to investigate the effect of learners’ altruistic teaching on their emotion regulation. The study followed a sequential explanatory comparison group pre-test–post-test design. One hundred forty-one English as a Foreign Language (EFL) learners were recruited for this intervention study and were divided into experimental and control groups. Learners in the experimental group performed altruistic teaching by teaching their peers how to write essays in English, whereas learners in the control group did group work tasks on English essay writing. The results of independent-sample t-tests and repeated-measures ANOVA showed that altruistic teaching significantly impacts EFL learners’ emotion regulation. The results of qualitative data pointed to five themes, including enjoyment, self-esteem, bonding, devotion, and progress. Overall, the results suggested that altruistic teaching impacts learners’ emotion regulation by enhancing their enjoyment, self-esteem, bonding, devotion, and progress. The paper has theoretical and pedagogical implications for SLA research and practice.
Extraordinary Diffuse Light in Hickson Compact Group 90

A two-color photometric study is presented for the interacting compact system of galaxies Hickson Compact Group 90 (HCG 90). Currently, HCG 90's galaxies are experiencing a strong tidal interaction, and as a result, a significant luminous diffuse light component has formed. Through isophotal definition of the distinction between the galaxy light and diffuse intracluster light, approximately 38%-48% of the total light belongs to the diffuse light component. Moreover, the surface brightness of the "tidal debris" is much higher than seen in other interacting systems. The intracluster light has a narrow color distribution centered around a mean color of V-R = 0.67 ± 0.03 mag, which is consistent with an old stellar population. Although a spiral galaxy is heavily involved in an interaction, an associated blue component to the diffuse light is not clearly seen. An interaction of this magnitude would also remove much of the cold gas in the interacting galaxies, which would then be heated by the group potential; however, Chandra observations reveal only a very faint intracluster medium at energy of kT ~ 0.7 keV. The X-ray-emitting gas shows a narrow bridge that connects two of the interacting galaxies. This morphology is similar to that exhibited by the diffuse optical emission. This morphology might be an indicator of a young dynamical age for this system. However, the overall luminosity ratio of X-ray gas emission to the diffuse light emission is less than 10-3, and this might indicate a dynamical old system (e.g., the gas has cooled). Therefore, HCG 90 is a dynamical paradox in that it has a very large amount of diffuse intracluster light and a very small amount of related hot intracluster gas and has overall features that give conflicting inferences concerning its dynamical age.
Anti-Inflammatory, Antimicrobial, Antioxidant and Photoprotective Investigation of Red Propolis Extract as Sunscreen Formulation in Polawax Cream

Many activities have been described for propolis, including, antiviral, antibacterial, antifungal, anti-inflammatory, immunoregulatory, antioxidant and wound healing properties. Recently, propolis has been highlighted due to its potential application in the pharmaceutical and cosmetic industries, motivating a better understanding of its antioxidant and anti-inflammatory activities. Propolis and its main polyphenolic compounds presented high antioxidant activity, and effectiveness as broad spectrum UVB and UVA photoprotection sunscreens. Through a qualitative phytochemical screening, the ethanolic red propolis extracts (EEPV) (70% at room temperature and 70% at a hot temperature) presented a positive result for flavonoids and terpenoids. It presented an antioxidant activity for reducing 50% of DPPH of 17 and 12 μg/mL for extraction at room temperature and at a hot temperature, respectively. The UPLC-QTOF-MS/MS analysis allowed the annotation of 40 substances for EEPV-Heated and 42 substances for EEPV-Room Temperature. The IC50 results of the ABTS scavenging activity was 4.7 μg/mL for both extractions, at room temperature and at a hot temperature. Additionally, we also evaluated the cytotoxic profile of propolis extracts against macrophage (RAW 264.7 cells) and keratinocytes (HaCaT cells), which showed non-cytotoxic doses in cell viability assays even after a long period of exposure. In addition, propolis extracts showed antibacterial activity for Gram-positive bacteria (Staphylococcus aureus and Staphylococcus epidermidis), demonstrating potential biological activity for the creation of formulations aimed at disease control and prevention.
Influences of arbuscular mycorrhizal fungi on crop growth and potentially toxic element accumulation in contaminated soils: A meta-analysis

Abstract Soil pollution from potentially toxic elements (PTEs) is a serious environmental issue worldwide that affects agricultural safety and human health. Arbuscular mycorrhizal fungi (AMF), as ecosystem engineers, can alleviate PTE toxicity in crop plants. However, the comprehensive effects of AMF on crop performance in PTE-contaminated soils have not yet been recognized globally. Here, a meta-analysis of 153 studies with 3213 individual observations was conducted to evaluate the effects of AMF on the growth and PTE accumulation of five staple crops (wheat, rice, maize, soybean, and sorghum) in contaminated soils. Our results demonstrated that AMF had strong positive effects on the shoot and root biomass. This is because AMF can effectively alleviate oxidative damage induced by PTEs by stimulating photosynthesis, promoting nutrition, and activating non-enzymatic and enzymatic defense systems in crop plants. AMF also decreased shoot PTE accumulation by 23.6% and increased root PTE accumulation by 0.8%, demonstrating that AMF effectively inhibited the PTE transfer and uptake by crop shoot. Meanwhile, AMF-mediated effects on shoot PTE accumulation were weaker in soils with pH > 7.5. Overall, this global survey has essential implications on the ability of AMF to enhance crop performance in PTE-contaminated soils and provides insights into the guidelines for safe agricultural production worldwide.

HUNTING FOR YOUNG DISPERSING STAR CLUSTERS IN IC 2574

Dissolving stellar groups are very difficult to detect using traditional surface photometry techniques. We have developed a method to find and characterize non-compact stellar systems in galaxies where the young stellar population can be spatially resolved. By carrying out photometry on individual stars, we are able to separate the luminous blue stellar population from the star field background. The locations of these stars are used to identify groups by applying the HOP algorithm, which are then characterized using color–magnitude and stellar density radial profiles to estimate age, size, density, and shape. We test the method on Hubble Space Telescope Advanced Camera for Surveys archival images of IC 2574 and find 75 dispersed stellar groups. Of these, 20 highly dispersed groups are good candidates for dissolving systems. We find few compact systems with evidence of dissolution, potentially indicating that star formation in this galaxy occurs mostly in unbound clusters or groups. These systems indicate that the dispersion rate of groups and clusters in IC 2574 is at most 0.45 pc Myr−1. The location of the groups found with HOP correlate well with H i contour map features. However, they do not coincide with H i holes, suggesting that those holes were not created by star-forming regions.
Contexts shaping the development and success of elite sport systems: a scoping review

ABSTRACT The importance of contexts in analysing elite sport systems and policies, as reflected in substantial research over the past couple of decades, is considered to nurture or constrain the development and outcome of elite sport systems toward international sporting success. Theorising elite sport systems as institutions operating and embedded in an open system may provide insight into the “hows” (throughput processes) and the “whys” (conditions) of the effectiveness of sport systems and policies to determine what may work (or not work) for each country’s specific context. This scoping review aims to examine and map determinants of elite sport development in nations. Specifically, the review analysed how studies: (1) theorised the determinants, (2) used terms to denote contextual determinants for elite sport development and success and (3) described or conceptualised context. Further, the review identified context dimensions derived from the elite sport development determinants. The scoping review identified 19 studies that contain relevant contextual determinants. Findings present seven context dimensions derived from a neo-institutional organisation framework that pertain to different institutional contexts that may influence the development of elite sport policy systems. An improved conceptualisation of context may enhance our understanding of the relationship between processes (i.e., sport policy mechanisms) and contexts. HIGHLIGHTS The scoping review analysed how studies: (1) theorised the elite sport determinants; (2) used terms to denote contextual determinants for elite sport development and success; and (3) described or conceptualised context. The scoping review identified 19 studies describing determinants of the development of elite athletes and sport systems in relation to success. Findings present seven context dimensions derived from a neo-institutional organisation framework that pertains to different institutional contexts that may influence the development of elite sport policy systems. Contextual determinants in the 19 studies can be categorised into seven different context dimensions, namely: (1) belief system; (2) historical development; (3) culture; (4) dominant interest groups; (5) legal rules and structures; (6) development standards of conduct and conventions; and (7) transnational influence. Further improved conceptual clarity on contextual dimensions of elite sport systems may enhance our understanding of the interdependent relationship between mechanisms (i.e., sport policy processes) and the contexts.
Prognostic Value of Monocarboxylate Transporter 1 Overexpression in Cancer: A Systematic Review

Energy production by cancer is driven by accelerated glycolysis, independently of oxygen levels, which results in increased lactate production. Lactate is shuttled to and from cancer cells via monocarboxylate transporters (MCTs). MCT1 works both as an importer and an extruder of lactate, being widely studied in recent years and generally associated with a cancer aggressiveness phenotype. The aim of this systematic review was to assess the prognostic value of MCT1 immunoexpression in different malignancies. Study collection was performed by searching nine different databases (PubMed, EMBASE, ScienceDirect, Scopus, Cochrane Library, Web of Science, OVID, TRIP and PsycINFO), using the keywords “cancer”, “Monocarboxylate transporter 1”, “SLC16A1” and “prognosis”. Results showed that MCT1 is an indicator of poor prognosis and decreased survival for cancer patients in sixteen types of malignancies; associations between the transporter’s overexpression and larger tumour sizes, higher disease stage/grade and metastasis occurrence were also frequently observed. Yet, MCT1 overexpression correlated with better outcomes in colorectal cancer, pancreatic ductal adenocarcinoma and non-small cell lung cancer patients. These results support the applicability of MCT1 as a biomarker of prognosis, although larger cohorts would be necessary to validate the overall role of MCT1 as an outcome predictor.
