We construct wavelets and derive a density condition of MRA in a higher-dimensional Sobolev space. We give necessary and sufficient conditions for orthonormality of wavelets in . We construct nonseparable orthonormal wavelets in a higher-dimensional Sobolev space by using multivariate box spline.

Background: Mental health problems are common in the working-age population. More knowledge is needed on how to support work participation and reduce sickness absence. The objective of the study was to estimate the distribution of mental well-being and work capacity in women and men in a working population and assess the association between mental well-being and work capacity, while adjusting for sociodemographic characteristics, health status, and working positions.

Yerba mate, a key crop in South America, is prized for its pleasant taste and high organoleptic quality, often linked to lower branch content. To quantify branch content and authenticate high-quality samples (less than 30 % m/m branch content), a Chemometrics-assisted Color Histogram-based Analytical System (CACHAS) was employed. Using Hue-Saturation-Value (HSV) histograms, Partial Least Squares (PLS) demonstrated excellent predictive performance, achieving a root mean square error (RMSEP) of 4.

Background: Physical activity during pregnancy is thought to influence birth outcomes, but its association with it is not fully understood. We aimed to examine the association of sedentary behavior during pregnancy with preterm birth and infant adiposity measured at birth, 14 weeks, and one year of age.
Methods: In this cohort study, physical activity during pregnancy was assessed using the physical activity questionnaire.

Objective: Experiencing intimate partner violence (IPV) can negatively impact young people's reproductive autonomy, including making it more challenging to get contraception. This study examined the association between IPV and delays in obtaining contraception in a sample of young women from California and Texas.
Study Design: The data are from a supplementary study to a cluster randomized controlled trial conducted with young people sexually-active within the past year recruited at 29 community colleges during the COVID-19 pandemic (May 2020-May 2023).

Despite rising concerns about alcohol use in artisanal mining, a focused investigation into its psychosocial drivers and mental health implications within sub-Saharan Africa's informal mining sector remains scarce. This study investigates the prevalence, motivations, and the association between alcohol use and mental health outcomes (depression, anxiety, and stress) among artisanal miners in Ghana. Using community based cross-sectional survey data from 664 miners, alcohol use was assessed using the Alcohol Use Disorders Identification Test, while symptoms of anxiety, stress, and depression were measured via the GAD-7, PSS, and PHQ-9 instruments.
