Random composites with nickel networks hosted randomly in porous alumina are proposed to realize double negative materials. The random composite for DNMs (RC-DNMs) can be prepared by typical processing of material, which makes it possible to explore new DNMs and potential applications, and to feasibly tune their electromagnetic parameters by controlling their composition and microstructure. Hopefully, various new RC-DNMs with improved performance will be proposed in the future.

Objective: This study assessed the association between baseline sociodemographic variables, body composition and 4-year changes in the intake of food groups, including sugar sweetened beverages (SSBs) among children, after implementation of the health promotion levy.
Design: Prospective cohort study.
Setting: 10 schools in North West Province, South Africa.
To determine if the use of theory, data and end-user perspectives to guide an adaptation of the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) yields better outcomes and improves the "fit" of TranS-C to community mental health centers (CMHCs), relative to the standard version. Ten counties in California were cluster-randomized by county to Adapted or Standard TranS-C. Within each county, adults who exhibited sleep and circadian dysfunction and serious mental illness (SMI) were randomized to immediate TranS-C or Usual Care followed by Delayed Treatment with TranS-C (UC-DT).

The aim of the current study was to systematically review and quantify the findings of randomized controlled trials (RCTs) assessing the effect of fermented soy products on anthropometric indices, body composition, and metabolic outcomes. PubMed, Scopus, and Web of Science were searched to identify the relevant articles from inception until March 2024. The weighted mean differences (WMD) and corresponding 95% confidence intervals (CI) were calculated as effect sizes and analyzed using the random-effects method.

To achieve superior energy storage performance in dielectric polymer films, it is crucial to balance three key properties: high dielectric constant, high breakdown strength, and low dielectric loss. Here, we present the realization of ultrahigh efficiency and energy density in electrospun MBene/PEI composite films, achieved through an in-plane aligned doping pattern. The 1.

Background: Both the basal metabolic rate (BMR) and excess postexercise oxygen consumption (EPOC) can be influenced by physical training and are associated with body composition and aerobic capacity. Although a correlation between the two is expected, this relationship has not been explored. Our hypothesis is that a higher BMR is correlated with lower EPOC.
