We report the results of new differential force measurements between a test mass and rotating source masses of gold and silicon to search for forces beyond Newtonian gravity at short separations. The technique employed subtracts the otherwise dominant Casimir force at the outset and, when combined with a lock-in amplification technique, leads to a significant improvement (up to a factor of 10^{3}) over existing limits on the strength (relative to gravity) of a putative force in the 40-8000 nm interaction range.

Measurement of Blood Pressure in Children and Adolescents Outside the Office for the Diagnosis of Hypertension.
Curr Cardiol Rep
January 2025
Section of Pediatric Nephrology, Department of Pediatrics, Yale University School of Medicine, New Haven, USA.
Purpose Of Review: To review the benefits of ambulatory blood pressure monitoring and home blood pressure monitoring in children and to discuss implementation of guideline-recommended ambulatory blood pressure monitoring.
Recent Findings: Compared with office blood pressure, ambulatory blood pressure monitoring and home blood pressure monitoring provide superior accuracy, reproducibility, and stronger associations with target organ damage although future work is needed to determine the utility of home blood pressure monitoring to predict hypertension status on ambulatory blood pressure monitoring. Due to the benefits of out-of-office blood pressure measurement, ambulatory blood pressure monitoring has been recommended to confirm the diagnosis of hypertension in children and adolescents since publication of the 2017 American Academy of Pediatrics clinical practice guidelines on hypertension.
Exogenous diethyl aminoethyl hexanoate alleviates the damage caused by low-temperature stress in Phaseolus vulgaris L. seedlings through photosynthetic and antioxidant systems.

Background: Phaseolus vulgaris is a warm-season crop sensitive to low temperatures, which can adversely affect its growth, yield, and market value. Exogenous growth regulators, such as diethyl aminoethyl hexanoate (DA-6), have shown potential in alleviating stress caused by adverse environmental conditions. However, the effects that DA-6 has on P.

January 2025
School of Public Health, Division of Health Policy and Management, University of California, Berkeley, Berkeley, CA, USA.
Background: External incentives increasingly encourage hospitals to address health-related social needs, yet limited evidence exists about whether social needs interventions are associated with quality indicators like potentially preventable admissions.
Objective: We analyze whether four hospital interventions-meal delivery, transportation to health services, mobile clinics, and community-oriented violence prevention programs-are associated with potentially preventable hospitalizations.
Design: Cross-sectional analysis of survey-based and claims-based data.
Dissemination of genes associated with antibiotic resistance and bacterial virulence during ecosystem succession in two Tibetan glacier forefields.

The release of pathogens and DNA from the cryosphere (glacier, permafrost, and, sea ice) has become a new threat to society and environment. Due to enhanced glacier retreat, the size of glacier forefields has greatly expanded. Herein, we used a combination of metagenomic and metatranscriptomic methods and adopted a sequence-based approach to investigate the distribution and changing patterns of virulence factor genes (VFGs) and antibiotic resistance genes (ARGs) in two glacier forefields.

This study investigates the impact of low-carbon economic policies on Corporate Environmental Responsibility (CER) in Chinese A-share listed companies, with a particular focus on the role of financing constraints as a mediating factor. Despite a decrease in environmental pollution incidents in 2022, the economic and social impacts of such incidents remain significant, highlighting the need for stronger environmental governance. Building upon previous research, this study utilizes data from the Shanghai and Shenzhen stock exchanges (2010-2020) and employs a Difference-in-Differences (DID) model to assess the effects of low-carbon economic policies introduced in 2016 on CER.
