North American Indigenous (NAI) youth suffers disproportionately from consequences associated with alcohol use. Previous research has found that positive alcohol expectancies are robustly related to alcohol consumption among NAI youth and that changes in alcohol consumption are associated with concurrent changes in happiness. However, no work to date has examined the relation between happiness and alcohol expectancies, or the influence of happiness on the association between alcohol expectancies and alcohol consumption. First Nation adolescents between the ages of 11 and 18 living on a rural reserve in Eastern Canada ( = 106, = 14.6 years, 50.0% female) completed a pencil-and-paper survey regarding their subjective happiness, positive alcohol expectancies, and alcohol consumption. Moderation analyses revealed a significant main effect of subjective happiness ( = -.10, < .001) but not alcohol expectancies ( = .02, = .14) on alcohol consumption. The interaction of alcohol expectancies and subjective happiness was significant, ( = -.01, = .002). Analysis of simple slopes revealed that the effect of alcohol expectancies on alcohol consumption was significant for those reporting low ( = .07, = .001), but not high levels of subjective happiness ( = -.02, = .25). Results of the present study provide preliminary support for the utility of positive psychological interventions aiming to increase adolescent's subjective happiness to indirectly target alcohol consumption. Future work should test the effectiveness of such interventions and aim to replicate these findings in larger samples. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

We propose a novel contactless droplet manipulation strategy that combines electrostatic tweezers (ESTs) with lubricated slippery surfaces. Electrostatic induction causes the droplet to experience an electrostatic force, allowing it to move with the horizontal shift of the EST. Because both the EST and the slippery operating platform prepared by a femtosecond laser exhibit a strong binding effect on droplets, the EST droplet manipulation features significant flexibility, high precision, and can work under various operating conditions.

Background And Aims: Acute-on-chronic liver failure (ACLF) has a 22%-74% 28-day mortality rate and 30%-40% 30-day readmission rate. We investigated the acceptability and feasibility of a multimodal community intervention for ACLF.
Methods: A single-arm nonrandomized pilot study of consecutive participants with ACLF was conducted in a tertiary health service.

Mechanical interatomic bond formation under ultrahigh pressure induced by laser-driven shock waves has been demonstrated for C-C, C-O, and O-O bonds. In this study, molecules generated in primary amine solutions irradiated with high-intensity lasers were identified. When methylamine or ethylamine was dissolved in methanol or ethanol, molecules likely formed through C-C or O-N bonds between the amine and alcohol were detected.
