Novel Statistical Modelling and Optimization Techniques of Fading Channel Coefficients for 5G Network Performance
Authors: Sabuncu Özlem , Bilgehan Bülent 
Published: February 2025

Abstract
The channel estimation process (CE) is a pivotal element in wireless communication employing orthogonal frequency division multiplexing (OFDM) modulation. The derived coefficient can represent the channel characterization. A newly proposed model derived for fifth-generation (5G) network and future communication systems two encounter the fading effects of the channel. The proposed model improves the channel estimation accuracy by incorporating precise measurements of channel coefficients, enhancing the overall performance. The model uses least square (LS) and minimum mean squared error (MMSE) optimization algorithms for the channel coefficient extraction process. The effectiveness of the proposed model has been experimentally confirmed using different fading channel scenarios in the literature. The mean square error (MSE) and bit error rate (BER) test criteria are used for performance measures. The test was generalized using a 64, 256 and 1024 quadrature amplitude modulation (QAM) scheme, demonstrating the model’s applicability to various communication scenarios. The proposed model was evaluated alongside several state-of-the-art statistical channel estimation methods to demonstrate its performance across various tests. When compared to pilot-based estimation, the model consistently exhibits superior accuracy and adaptability, ensuring dependable performance in a wide range of communication scenarios. Additionally, the proposed model is better suited to handle the complexity of non-line-of-sight (NLOS) and multipath environments, offering a more nuanced approach compared to pilot signals, which often rely on idealized assumptions of channel linearity.

Abstract
Nanofluids have found widespread application across various systems to enhance heat transfer, albeit with the simultaneous occurrence of fouling on heat exchange surfaces. In examining the impact of particulate fouling from nanoparticles on the heat transfer behavior of heat exchangers, this study conducted an experimental exploration utilizing green functionalized clove-treated graphene nanoplatelets (CGNP) nanofluid within a double-pipe heat exchanger (DPHE). Previous studies on nanofluids as heat transfer fluid have largely ignored the impact of particulate fouling on heat transfer performance over time. Various concentrations (0.025, 0.075, and 0.1 mass%) and flow rates (8 and 12 L min−1) were systematically examined over an extended operational time, with distilled water (DW) employed as a reference liquid for comparison. The experimental data were compared with simulation results at five different flow rates. The findings reveal that DW exhibited the highest overall heat transfer coefficient (OHTC) among all tested fluids with an OHTC of approximately 1660 W m2 K−1. Conversely, deposition occurred in the CGNP nanofluid at all concentrations over an extended operational period. Specifically, the 0.025 mass% concentration demonstrated the lowest fouling resistance in the developing stage. The fouling resistance reached constant for all the tested concentrations with estimated values of 0.15–0.16 m2K kW−1. Furthermore, a flow rate of 12 L min−1 was shown to reduce the fouling resistance by 50% when decreasing the flow rate to 8 L min−1. Overall, applying CGNP nanofluid in the DPHE over a prolonged testing duration was deemed ineffective. Exploring optimized techniques to mitigate the deposition of CGNP particles on the heat exchange pipe surfaces is necessary.

Gender gap in reported childcare preferences among parents
Authors: Pertold Filip , Sinani Sofiana , Šoltés Michal 
Published: February 2025

Abstract
The child penalty explains the majority of gender employment and wage gaps. However, less is known about the factors driving the child penalty itself. In this paper, we explore the gender gap in childcare preferences, a potential contributor to the child penalty. We surveyed parents of young children and elicited the minimal compensation they would require to stay home to care for a child. Mothers require less compensation for childcare than fathers; the estimated gender gap in childcare preferences is CZK 2500 monthly (EUR 100), 7.6% of the median female wage, and cannot be explained by gender differences in labor market opportunities or prosocial motives to care for a family member. We further document a widespread misperception of fathers’ preferences, as respondents incorrectly expect fathers to require less compensation to care for a child than to care for an elderly parent.

Published: February 2025

Abstract
The objective of this study is to examine the impact of the gender of editors and authors, as well as their interaction, on acceptance delays (ACCDEL) of articles. We focus on genders of the corresponding author and the editor overseeing the manuscript. Using data from three top accounting journals from 2015 to 2020, we conduct a regression analysis to test the hypotheses regarding longer ACCDEL for articles under female editorship or authors, those with gender-opposite editor-author pairs, and those with coincident genders editor-author pairs. We find that when the genders of editors and corresponding authors differ, there is a significant increase in ACCDEL compared to submissions where the genders of editors and corresponding authors match. Our results suggest the existence of a prevalent gender homophily effect.
Who Cares? Stereotypes of and Support for Men Working in Childcare
Authors: Haines Serena , Sczesny Sabine , Graf Sylvie 
Published: February 2025

Abstract
Men are vastly underrepresented in early childhood education and care, particularly in childcare work. To uncover stereotypes that motivate or hinder support for men in childcare in society, we employed a representative sample (N = 280) from Czechia, which has one of the lowest percentages of men working in childcare in the EU. We identified and contrasted descriptive, prescriptive, and proscriptive stereotypes about men, women, or childcare workers without a specified gender. Next, we examined the link between convergence of descriptive and prescriptive stereotypes about men in childcare and support for men working in childcare. In both open responses and trait ratings, men working in childcare were less often perceived or expected to be warm than women working in childcare. In the trait ratings, men working in childcare were less often expected to be moral and competent than women working in childcare. Yet, the overall stereotypical profiles of men converged with childcare workers with no gender information. Greater convergence between descriptive and prescriptive stereotypes about men working in childcare was associated with higher support for them. These findings highlight the specific role that normative beliefs play in support for men in childcare in the larger social environment.
A tale of two worlds: spatial arrangement of avian communities in a Neotropical city

Published: February 2025

Abstract
Urbanization is considered one of the most critical processes related to biodiversity loss worldwide. Birds are one of the most commonly studied groups in urban ecosystems due to their quick response to environmental changes. Despite the current knowledge related to urban bird communities, information associated with the specific factors shaping avian communities in cities is still scarce, especially in the Neotropics. In this study, we performed a citywide survey for birds in the city of Xalapa (Mexico), to compare the species composition of urban communities with those of two reference sites adjacent to the urban area. We hypothesized that the compositional similarity would either be defined by their spatial proximity to their respective reference site or that it would be shaped by resources intrinsic to the city. Considering the nature of our data, we performed a subgroup analysis using randomly selected groups for the urban and reference sites to compare similar samples. We used Sørensen (incidence-based) and Bray-Curtis (abundance-based) cluster analyses and found that the urban bird community composition is better explained by the vegetation cover than by the proximity to the reference sites. We confirmed this association with the results of the GLM, showing a statistically significant association with the vegetation cover. Our results are relevant in terms of urban design, considering that promoting the improvement of vegetation in cities could potentially help avian communities in these changing environments.

Published: February 2025

Abstract
Mechanical processes impact (conventional mixing, high-speed shear mixing, and ultrasonication) on the physicochemical, mechanical, and thermal properties of starch gels combined with plant protein concentrates (pea, fava-bean, pumpkin, rice) and κ-carrageenan were evaluated. Conventional and high-speed shear mixing reduced values of strain (γl), yield stress (τf) storage modulus (G’), complex viscosity (η*), and increased tanδ magnitudes, being more prominent in fava-bean (G’PSF C= 11416 ± 48, G’PSF HS = 5421 ± 37), pea (G’PSP C= 6188 ± 39 G’ PSF HS = 2984 ± 30), and pumpkin protein-starch gels (G’PSPU C= 14840 ± 107, G’PSF HS = 7066 ± 42), (p < 0.05).While no significant rheological alterations were observed for rice-protein gels (G’PSR C= 10802 ± 98, G’PSR HS = 10044 ± 76). Ultrasonication process had a smaller effect on viscoelastic properties compared to other shear methods (e.g. G’PSP C= 6188 ± 39, G’PSP US = 5775 ± 72). Firmness increased with high shear processing, ∼ 3 times for fava bean and ∼ 2 times for pea and pumpkin protein-starch gels. In contrast, shearing of rice protein-starch complex resulted in softer gels, particularly with ultrasound treatment. The thermomechanical properties displayed shear-induced changes in onset, peak, and conclusion temperatures of gelatinization, and decreased enthalpy values, with varying sensitivity to each protein concentrate. Research findings have important implications for optimizing food product development by customizing processing techniques and hydrocolloids interactions to achieve desired texture and functionality in various food applications such as extrusion-based three-dimensional food-printing.

Abstract
The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) is increasing globally, posing a major public health issue. This study analyzes the global, regional, and national burden of MASLD and its risk factors from 1990 to 2021, with projections to 2030. We obtained data on MASLD prevalence, deaths, and disability-adjusted life years (DALYs) from the Global Burden of Disease 2021 for 204 countries. Counts and rates per 100,000 population were calculated, and trends to 2030 were predicted using the Bayesian Age-Period-Cohort model. In 2021, there were 1,267.9 million MASLD cases globally, with 138.3 thousand deaths and 3667.3 thousand DALYs. The global age-standardized prevalence, death, and DALY rates were 15,018.1, 1.6, and 42.4 per 100,000 population, increasing by 24.3%, 5.5%, and 5.5% since 1990. North Africa and the Middle East had the highest prevalence, while Andean and Central Latin America had the highest death and DALY rates. Men aged 15–69 and 90–94 had higher DALY rates, while women aged 70–89 and 95+ had higher rates. A reversed V-shaped association was found between the sociodemographic index and DALY rate. High fasting plasma glucose (5.9%) and smoking (2.4%) were major risk factors. Public health efforts should prioritize early detection and management of MASLD in younger populations and develop targeted strategies for older adults, especially women, to reduce the disease burden. Effective policies to address high fasting plasma glucose and smoking can mitigate MASLD’s impact.
Hypertension, Obesity, and Target Organ Injury in Children: An Emerging Health Care Crisis
Authors: Tran Andrew H. , Walsh Aaron , Urbina Elaine M. 
Published: February 2025

Abstract

Purpose of Review
To review data regarding the association between hypertension and childhood obesity on target organ damage. We will also review data regarding the impact of intervening on hypertension and childhood obesity on target organ damage.

Recent Findings
The prevalence of hypertension and obesity are rising in children despite efforts to address these risk factors. Health disparities play a role in contributing to the rise in prevalence. Hypertension and obesity promote pro-inflammatory cytokines that activate the renin-angiotensin-aldosterone system and sympathetic nervous system which result in adverse effects on blood pressure regulation and renal function. Adverse cardiac, vascular, renal, neurocognitive, and retinal changes can be seen with elevated blood pressure. Recent intervention studies are few, but adequate treatment of hypertension and obesity can result in improvement in target organ damage.

Summary
Hypertension and obesity have significant impacts upon target organs. Interventions to decrease blood pressure and treat obesity are associated with reductions in left ventricular hypertrophy, improvement in measures of systolic and diastolic function, and improvement in renal outcomes. Appropriate screening and management of these conditions can lessen potential future cardiovascular impact.
Responses of Non-Target Arthropods to the dsRNA Bioinsecticide Calantha™ and Conventional Insecticides Targeting Colorado Potato Beetle, Leptinotarsa Decemlineata (Say)

Published: February 2025

Abstract
Management of the Colorado potato beetle (Leptinotarsa decemlineata) is reliant on conventional insecticides that can negatively affect non-target arthropods. Calantha™ (active ingredient: ledprona) is a sprayable double-stranded RNA biopesticide specific for L decemlineata proteasome subunit beta 5 gene that triggers the RNA-interference pathway and is designed to have limited non-target effects. To test this hypothesis, we conducted two years of field trials in Idaho, Wisconsin, and Maine comparing arthropod responses to different insecticide regimes, with and without Calantha, targeting the Colorado potato beetle. Comparisons of arthropod abundance among treatments showed no evidence of effects of Calantha on non-target arthropods, including beneficials (predators, parasitoids), “neutrals” (i.e., non-pests), and other beetle species. Conventional insecticides generally showed more non-target effects, and responses were always stronger for arthropods from vacuum samples than pitfall samples. Insecticide programs featuring Calantha, especially in rotation with other biorational products, may reduce pests while preserving beneficial arthropods and contribute to biological control of arthropod pests in potato fields.

Published: February 2025

Abstract
In 2016, Dematophora necatrix, the causal agent of white root rot (WRR), was identified in an avocado orchard in South Africa. Since then, this pathogen has spread to all avocado-growing regions in the country. This study aimed to evaluate the in-field efficacy of the biological control product EXTRASOL (Bacillus subtilis and Bacillus amyloquefaciens subsp. plantarum) and the fungicide fluazinam against WRR in two commercial avocado orchards in Tzaneen, Limpopo, South Africa. Over two growing seasons (2022 and 2023), disease severity, the number of D. necatrix-positive baits, and leaf area index (LAI) were monitored. Results showed that fluazinam significantly improved the health of WRR-symptomatic trees. At the start of the trial, symptomatic trees exhibited an average disease severity score of 4, which significantly declined to near 0 after two years, with symptoms largely absent. LAI of symptomatic trees treated with Fluazinam was significantly higher (> 4) in both orchards after two years. The combination of fluazinam and EXTRASOL performed similarly to fluazinam alone, while EXTRASOL alone provided minor benefits. Fluazinam residues also fell below detectable limits in the fruit of treated trees as soon as 2 weeks following treatment. These findings support fluazinam as a safe and effective treatment for WRR in South African avocado orchards.

Published: February 2025

Abstract
This study presents the synthesis and characterization of a novel electrocatalyst based on cobalt (II)-tetra aminophenyl porphyrin (CoTAPor) conjugated non-covalently with an iron (III) oxide-reduced graphene oxide (Fe2O3rGO). The synthesized materials were then used to modify a glassy carbon electrode (GCE), with CoTAPor-Fe2O3rGO identified as the superior electrocatalyst. The electrochemical detection of 4-hydroxybenzoic acid (pHBA) was performed on the CoTAPor- Fe2O3rGO-modified GCE using cyclic voltammetry (CV) and chronoamperometry (CA). The CoTAPor-Fe2O3rGO composite exhibited the best catalytic performance, showing a significantly higher current response compared to bare GCE, CoTAPor, and Fe2O3rGO individually under CV and CA. This enhanced performance is attributed to the synergistic interactions between CoTAPor and Fe2O3rGO, resulting in increased sensitivity and a lower limit of detection (LoD). For CoTAPor-Fe2O3rGO, the sensitivity was 0.761 µA µM−1, with a LoD of 1.18 µM (S/N = 3). In addition, the electrocatalyst demonstrated good selectivity for pHBA in the presence of potentially interfering substances under controlled experimental conditions.

Published: February 2025

Abstract
Economic sectors that drive nature decline are heavily subsidized and produce large environmental externalities. Calls are increasing to reform or eliminate subsidies and internalize the environmental costs of these sectors. We compile data on subsidies and externalities across six sectors driving biodiversity loss—agriculture, fossil fuels, forestry, infrastructure, fisheries and aquaculture, and mining. The most updated estimates suggest that subsidies to these sectors total between US$1.7 and US$3.2 trillion annually, while environmental externalities range between US$10.5 and US$22.6 trillion annually. Moreover, data gaps suggest that these figures underestimate the global magnitude of subsidies and externalities. We discuss the need and opportunities of building a baseline to account for the costs of subsidies and externalities of economic activities driving nature decline. A better understanding of the complexity, size, design, and effects of subsidies and externalities of such economic sectors could facilitate and expedite discussions to strengthen multilateral rules for their reform.

Published: February 2025

Abstract
The protracted complex emergencies in Somalia, exacerbated by natural disasters and civil conflicts, have precipitated a humanitarian crisis with profound implications for displacement and mental health, disproportionately affecting the most vulnerable Somalis. This study investigates the specific impacts of exposure to natural disasters and polytrauma on the social functioning of Somali youth in urban Kenya. A cross-sectional survey was conducted with 336 Somali youth in Eastleigh, Nairobi, utilizing snowball sampling. The survey measured demographics, trauma exposure, psychosocial factors, and social functioning, with advanced statistical analysis identifying significant predictors. The results underscore the profound effects of natural disaster exposure on social functioning within the context of polytrauma. Findings also emphasize gender, documentation status, help-seeking behaviors, and substance use as significant factors shaping social functioning. The analysis emphasizes the complex interplay between socio-environmental factors and trauma exposure, advocating for holistic interventions tailored to the unique challenges of complex emergencies. Additionally, findings suggest incorporating strategies to enhance resilience, social support, and coping mechanisms for populations experiencing hostile socio-legal environments.
