The preference of water self-ions (hydronium and hydroxide) toward air/oil-water interfaces is one of the hottest topics in water research due to its importance for understanding properties, phenomena, and reactions of interfaces. In this work, we performed enhanced-sampling molecular dynamics simulations based on state-of-the-art neural network potentials with approximate M06-2X accuracy to investigate the propensity of hydronium and hydroxide ions at air/oil(decane)-water interfaces, which can simultaneously describe well the water autoionization process forming these ions, the recombination of ions, and the ionic distribution along the normal distance to the interface by employing a set of appropriate Voronoi collective variables. A stable ionic double-layer distribution is observed near the air-water interface, while the distribution is different at oil-water interfaces, where hydronium tends to be repelled from the interface into the bulk water, whereas hydroxide, with an interfacial stabilization free energy of -0.

Cardiology Division, Massachusetts General Hospital, Harvard Medical School, Boston (Y.L., J.L.J., G.D.L.).
Background: Objective indices of functional capacity in patients with diabetic cardiomyopathy and stage B heart failure (HF) have not been comprehensively defined. We sought to characterize the cardiopulmonary exercise characteristics of individuals with diabetic cardiomyopathy at high risk for overt HF.
Methods: The relationships from cardiopulmonary exercise testing with clinical and laboratory characteristics of participants with diabetic cardiomyopathy were evaluated using baseline data from the ARISE-HF trial (Aldose Reductase Inhibition for Stabilization of Exercise Capacity in Heart Failure).
The mediating effect of clinical belongingness on the relationship between anxiety and professional identity in nursing interns: a cross-sectional study.

Nursing Department of Mianyang Central Hospital, School of Medicine, University of Electronic Science and Technology of China, Mianyang, Sichuan, China.
Background: Previous studies have reported that anxiety negatively affects professional identity (PI), and clinical belongingness is positively correlated with PI among nursing interns. However, little is known about the relationship between anxiety, PI, and clinical belongingness among nursing interns.
Objective: To explore the relationship between PI, clinical belongingness, and anxiety among nursing interns, and to demonstrate the mediating role of clinical belongingness in this relationship.

This research addresses the gap in efficient thawing methods by investigating the effects of ohmic thawing variables and freezing methods on the thawing speed and quality attributes of ground turkey breast, aiming to identify the optimal ohmic thawing method and compare it with traditional air and water thawing techniques. The variables for ohmic thawing consisted of voltage gradient (10, 15, and 20 V/cm), freezing method (Snap (rapid freezing of samples in liquid nitrogen at -210 °C), -70, and -20 °C), and probe type. The results showed that the snap-freezing method demonstrated superior functional and quality characteristics.
