Published: February 2025

IntroductionRainfall patterns are expected to become increasingly erratic as a result of global climate change, with more intense but less frequent rainfall events leading to an increased occurrence of drought events. This process may lead to significant declines in vegetation cover and subsequent increases in soil erosion, consequently accelerating the bury of detached litter by soil deposition and the mixture of residues from different plant species. Responses of litter decomposition to increasing rainfall variability in distribution and subsequent litter mixing or soil cover have scarcely received attention.MethodsTo fill this gap in our knowledge, we analyzed the influence of rainfall variability, soil cover, and litter mixing on shrub-species litter decomposition in a semi-arid shrubland. We explored the effects of redistributing the frequency and amount of precipitation on surface and belowground decomposition of litter from two separate or mixed predominant shrubs.ResultsDecomposition of belowground litter was consistently higher than that of surface litter over the entire field-incubation process. Mass loss significantly decreased in surface litter but not in belowground litter due to the lower frequency and larger amount of precipitation compared to the control treatment. Furthermore, exclusion of 30% precipitation had no significant effects on decomposition of either surface or belowground litter. We observed stronger synergistic effect for belowground litter mixture relative to surface litter mixture of the two shrubs, especially in the hotter months over the 5-month incubation.DiscussionThese findings support that rainfall variability in terms of distribution pattern rather than in the amount controls the litter decomposition on the soil surface in the semi-arid shrubland. Meanwhile, soil burial or litter mixing have greater effects on litter decomposition, individually or jointly. Together, our results highlight the need to consider rainfall distribution variability and incorporate soil-covering and litter-mixing as driving factors of organic matter turnover in drylands.

IntroductionThe quantitative modeling of dynamic branch growth in Korean pine (Pinus koraiensis) and the analysis of the factors influencing branch growth are essential prerequisites for making scientifically sound management decisions in Korean pine plantations. To date, the effects of competition, climate and their interactions on branch growth have been insufficiently investigated. Additionally, limited knowledge exists regarding whether these impacts vary depending on the social status of trees. In the face of the current challenges posed by climate change, accurate information to inform forest management and policy-making is urgently needed.MethodsWe collected 745 branches from 54 sampled trees of Korean pine and, we employed a mixed-effects model to assess the effects of tree variables, competition, climate, and their interactions on branch growth. Furthermore, we simulated branch growth under different combinations of competition and climatic conditions to provide practical and targeted recommendations for Korean pine plantation management.ResultsOur results demonstrate that (1) in addition to branch age, size, and tree height growth, competition, climate, and their interactions significantly improved the branch growth model, with the effects of interactions surpassing the individual effects of climate, which highlights the importance of considering interactive effects; (2) the effects of climate and competition varied depending on the social status of the trees, with dominant and intermediate individuals showing greater sensitivity to competition and climate than suppressed individuals, suggesting that, for future research in this direction, prioritizing sampling of dominant and intermediate individuals would be a cost-effective approach; and (3) owing to the presence of interactions, the influence of climate on branch growth was modulated by competition, suggesting that adjusting competition levels in response to climate stress could lead to desirable branch growth outcomes.DiscussionOur study underscores the importance of understanding the different sources of variation in branch growth is crucial for advancing our understanding of tree growth and crown dynamics, as well as for formulating sustainable management policies amidst the uncertainties of climate change.

Published: February 2025

IntroductionWomen of reproductive age (18–44 years) are at an increased risk of developing obesity due to pregnancy, life-transitions, and marginalization. Obesity in women negatively affects women’s health and pregnancy outcomes and can increase risk their children will develop obesity. Less is known about obesity risk at the interpersonal and environmental levels for women of reproductive age. This study uses the socioecological model to explore women’s obesity risk across ecological levels.Materials and methodsA secondary cross-sectional analysis was conducted using baseline data (March 2019–June 2022) from the cluster-randomized Healthy Eating and Active Living Taught at Home (HEALTH) Dissemination and Implementation study. Descriptive statistics and multivariate logistic regression models were used to determine associations between individual, interpersonal, and environmental level factors with weight status (overweight vs. obesity).ResultsAmong 221 participants (43% Hispanic/Latino, 51% High school or less), 37% were overweight and 63% had obesity. Interpersonal and environmental factors were not statistically significantly associated with obesity relative to overweight in bivariate analyses. In multivariate models, individual level factors of high/moderate physical activity (OR = 0.47, 95% CI: 0.26,0.84, p = 0.01) and food insecurity (OR = 2.51, 95% CI: 1.33,4.71, p = 0.00) were statistically significantly related to risk of having obesity compared to being overweight.DiscussionPhysical activity and food insecurity were associated with obesity in this study. Associations with interpersonal and environmental level factors were not statistically significant, which may be due to limited sample size or measures available to assess these levels. Future studies should investigate structural determinants (e.g., economic, neighborhood and physical environment), which may drive physical activity and food insecurity.

BackgroundComputer vision syndrome refers to a range of eye and vision-related problems which may result from extended use of digital devices such as computers. It is a public health problem, affecting more than 70% of all computer users. In developing countries like Ethiopia, there is scarcity of studies on computer vision syndrome, particularly in the telecom industry making evidence-based interventions difficult. Hence, the study aims to identify the determinants and the prevalence of computer vision syndrome among Ethio telecom workers in Addis Ababa, Ethiopia.ObjectivesThis study aimed to determine the prevalence of CVS and identify its factors among Ethio telecom workers in Addis Ababa, Ethiopia.MethodsInstitution-based cross-sectional study was conducted among Ethio telecom employees in Addis Ababa, Ethiopia from March to June 2023. A total of 497 individuals participated in the study. Data were collected using an interviewer- administered questionnaire through Kobo Toolbox, observational checklist and an illuminance measuring instrument. The data were transferred to Statistical Package for the Social Sciences (SPSS) version 26 for analysis. Multivariable logistic regression was performed to assess the association and control for potential confounders.ResultsThe prevalence of CVS among Ethio telecom workers was 68.8% (95% CI: 64.5–72.9). Significant associations were observed with viewing distance &lt;50 cm (AOR: 2.32, 95% CI: 1.24–4.33), improper task illumination (AOR: 1.78, 95% CI: 1.09–2.91), habit of taking breaks (AOR: 0.439, 95% CI: 0.281–0.686), and adjustment of brightness and contrast (AOR: 0.39, 95% CI: 0.22–0.68).ConclusionMore than two-thirds of Ethio telecom workers in Addis Ababa suffer from CVS, with significant influences from viewing distance, task illumination, breaks, and monitor settings. These findings underscore the need for interventions to enhance working conditions and reduce CVS prevalence among computer users.

IntroductionSleep app use has become widespread in recent years. Still, understanding of characteristics of users and the impact of sleep app usage remains limited.MethodsA sample of 940 young adults (18–30 years) living in the UK were recruited from Prolific (online research platform offering researchers access to survey panels) and invited to participate in a survey on the use and experience with sleep apps. Both sleep app users and non-users were invited. The survey included questions about demographics, morningness (Horne–Östberg Morningness–Eveningness Questionnaire-reduced scale), insomnia symptoms (Bergen Insomnia Scale), personality (HEXACO: Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness, and Openness to Experience), in addition to sleep app usage and how such use is experienced. A logistic regression analysis was conducted to identify characteristics of sleep app users. Factor analysis was used to elucidate dimensions of sleep app use experiences. Scores on the items making up each factor were then regressed on demographic variables, morningness, insomnia symptoms and personality.ResultsIn all, 36.8% of the participants reported using or having used sleep apps. Use was positively associated with age, insomnia symptoms, and conscientiousness. The factor analysis revealed three factors coined: trust/objectification (trust in sleep app results), negative (e.g., becoming stressed) and positive (e.g., prioritize sleep more) perceived effects. Trust/objectification was positively associated with age and agreeableness, and inversely related to high education and openness to experience. Insomnia symptoms and emotionality were associated with perceived negative effects. Morningness and male gender were associated with perceived positive effects whereas high education had an inverse relationship with perceived positive effects.DiscussionThe use of sleep apps was widespread. Different responses to sleep app usage were observed and linked to various individual variables. The findings suggest that perceived effects of sleep apps usage should be considered in light of individual differences. Research on sleep apps is still in its early stages, and several suggestions (recommendations) for future studies are outlined.
The impact of digital payments on the financial vulnerability of rural households: empirical evidence from China
Authors: Xu Fan , Zhang Lezhu 
Published: February 2025

IntroductionPoverty eradication is the primary goal of the United Nations 2030 Agenda for Sustainable Development (SDGs). Despite China’s significant achievements in poverty alleviation, many rural households still struggle to maintain a sustainable livelihood may even slip back into poverty due to ineffective risk responses when facing risks and challenges.MethodsThis study employs data from the 2017–2019 China Household Finance Survey to theoretically and empirically examine the impact and mechanisms of digital payments on the financial vulnerability of rural households.ResultsThe study’s results indicate that digital payments significantly reduce the financial vulnerability of rural households, a finding that remains robust even after accounting for endogeneity, employing alternative variable measurement approaches, and conducting propensity score matching tests. Mechanism analysis suggest that encouraging rural households to hold commercial insurance, engage in non-farm employment and expand their family social networks are key pathways by which digital payments impact the financial vulnerability of rural households. Further heterogeneity analyses reveal that digital payment plays a more substantial role in mitigating the financial vulnerability of rural households in the western region, which have low financial assets and high health risks, compared to those in the central and eastern regions, which have high financial assets and low health risks.DiscussionTherefore, this paper suggests that the government should continue to promote the in-depth integration of digital technology and financial services, strengthen the construction of rural digital infrastructure in areas lagging behind in traditional finance, enhance the comprehensive service function of digital payments, and enrich the coping strategies of farmers to mitigate financial vulnerability, while remaining vigilant about the potential consequences of digital payment.

Justificativa: A sífilis continua sendo um grave problema de saúde pública, principalmente em países em desenvolvimento, como o Brasil. Conhecer e divulgar os riscos de infecção por esta patologia é essencial para auxiliar nas medidas de prevenção e alertar os profissionais de saúde sobre a necessidade de investigação diagnóstica. A Profilaxia Pré-Exposição (PrEP) ao HIV é realizada com o uso de uma droga de forma programada, para evitar uma infecção por este vírus e está disponível no Brasil desde 2018. Objetivos: Descrever o perfil de tendência da sífilis adquirida no estado do Rio de Janeiro num período de 12 anos e especular se o uso da PrEP poderia influenciar no aumento de casos de sífilis no estado do Rio de Janeiro. Metodologia: Este é um estudo ecológico sobre Sífilis Adquirida nos últimos 12 anos (2012 a 2023) no estado do Rio de Janeiro. Os dados foram coletados no Sistema de Informação de Agravos de Notificação (SINAN). Resultados: As notificações de Sífilis Adquirida foram computadas em dois períodos distintos: 6 anos que antecedem a PrEP (2012 a 2017) e 6 anos Pós-PrEP (2018 a 2023). No período Pré-PrEP foram notificados 31.145 casos (60% masculino) e no período Pós-PrEP as notificações contabilizaram 114.053 casos (60% masculino). Os casos de Sífilis adquirida triplicaram (3,6 mais casos) após a insitutição da PrEP no estado do Rio de Janeiro. Conclusões: Nossa pesquisa confirmou uma estreita relação entre o aumento dos casos de sífilis em pessoas que utiliazaram a PrEP. Para o Rio de Janeiro são necessárias intervenções integradas de testagem e prevenção de IST, para mitigar a aquisição e transmissão de sifilis entre os usuários de PrEP.

Published: February 2025

Abstract
We demonstrate the fabrication and performance evaluation of physical reservoir computing (PRC) using a random network of gold nanoparticles (GNPs). We fabricated two random arrays of GNPs with six electrodes on one sample. Electrical measurements for each array and two parallelized arrays were conducted at temperatures of 4.2 K, 77 K, and 294 K. The random connections of GNPs brought varied tunneling resistances, resulting in various output voltages. The computational performance was assessed using the second-order nonlinear autoregression moving average task. The parallelized reservoir configuration achieved the normalized mean square error as small as 0.03 at 294 K. This higher performance was evaluated through information processing capability and was attributed to the increased second-order capacity at 294 K. Although PRC with GNPs was traditionally regarded to rely on the Coulomb-blockade-induced nonlinearity, nonlinear dynamics possibly due to thermal noise and non-uniform tunnel barriers were effective in reservoir calculations even at room temperature.
