Magnetocaloric Effect for a -Clock-Type System.

In this work, we study the magnetocaloric effect (MCE) in a working substance corresponding to a square lattice of spins with possible orientations, known as the "-state clock model". When the -state clock model has Q≥5 possible configurations, it presents the famous Berezinskii-Kosterlitz-Thouless (BKT) phase associated with vortex states. We calculate the thermodynamic quantities using Monte Carlo simulations for even numbers, ranging from Q=2 to Q=8 spin orientations per site in a lattice.

General Endotracheal Anesthesia vs Total Intravenous Anesthesia for Children Undergoing Low-Risk Cardiac Catheterization.

Historically, children undergoing cardiac catheterization have been managed with general endotracheal anesthesia (GETA). However, recent practice has favored general anesthesia with total intravenous anesthesia (TIVA). This study compares procedural outcomes in the pediatric cardiac catheterization laboratory (PCCL) for children undergoing low-risk cardiac catheterization with GETA vs.

Working memory needs pointers.

Cognitive neuroscience has converged on a definition of working memory (WM) as a capacity-limited system that maintains highly accessible representations via stimulus-specific neural patterns. We argue that this standard definition may be incomplete. We highlight the fundamental need to recognize specific instances or tokens and to bind those tokens to the surrounding context.

Tobacco, cannabis, alcohol, and polysubstance use disparities among sexual identity groups of US young adult women and men.

Background: Sexual minority young adults (SMYAs) display higher rates of polysubstance use (i.e., current use of multiple substances) than their heterosexual peers, but limited research has explored differences by gender and specific sexual identity.

The relationship of coping style and social support variation to glucocorticoid metabolites in wild olive baboons (Papio anubis).

Social support, via investment in relationships of importance with others, is often emphasized as a pathway towards mediating stress. The effectiveness of social support, however, can be altered by personality differences, but the physiological consequences of such covariation are still poorly explored. How do individual differences in the functioning of the stress response system mediate access to, and use of, social support? To examine this dynamic, we investigated glucocorticoids as a biomarker of energetic activation that may also be activated by chronic psychosocial stress.

Appeal and Sensory Characteristics of Oral Nicotine Products in Young Adults Who Vape E-Cigarettes.

Introduction: This study applied a novel tobacco regulatory science paradigm to characterize inter-product variation in the appeal and sensory features of emerging commercial and therapeutic oral nicotine products (ONPs) among young adults that vape e-cigarettes.

Methods: Twenty-three young adults without ONP experience who use e-cigarettes completed a single-blind, single-visit remote lab study. Participants rated appeal and sensory characteristics during 5-minute standardized self-administrations of 8 ONPs (4 fruit, 4 mint) from various brands (Lucy, Rouge, Solace, Nicorette, On!, Velo).

Minority stress mediates associations of sexual minority state policies and tobacco use among US sexual minority young adults.

Introduction: State policies surrounding sexual minority (SM) rights are associated with tobacco use among SM individuals. Research is scant regarding the role of distinct SM policy categories on SM young adults' (SMYAs) tobacco use and mechanisms explaining these associations.

Methods: We analyzed 2023 survey data from 1100 SMYAs (ages 18-34; 14.

A randomized controlled trial evaluation of a smoking cessation and physical activity intervention delivered via telemedicine in the Norton Sound region of Alaska.

Objectives: Tobacco use disproportionately affects Alaska Native people. Physical activity may aid quitting smoking and provides health benefits. We tested telemedicine-delivered heart health interventions in Alaska's Norton Sound region.

A formal analysis of the standard operating processes (SOP) and multiple time scales (MTS) theories of habituation.

In this article, we compare two theories of habituation: the standard operating processes (SOP) and the multiple time scales (MTS) models. Both theories propose that habituation is due to a reduction in the difference between actual and remembered stimulation. Although the two approaches explain short-term habituation using a similar nonassociative mechanism based on a time-decaying memory of recent stimulus presentations, their understanding of retention of habituation or long-term habituation differs.

Piezo channels modulate human lung fibroblast function.

Bronchial airways and lung parenchyma undergo both static and dynamic stretch in response to normal breathing as well as in the context of insults such as mechanical ventilation (MV) or in diseases such as asthma and chronic obstructive pulmonary disease (COPD) which lead to airway remodeling involving increased extracellular matrix (ECM) production. Here, the role of fibroblasts is critical, but the relationship between stretch- and fibroblast-induced ECM remodeling under these conditions is not well-explored. Piezo (PZ) channels play a role in mechanotransduction in many cell and organ systems, but their role in mechanical stretch-induced airway remodeling is not known.

Recall of Flavor at First E-cigarette Use and Its Association with E-cigarette Progression: The Mediating Effects of First Sensory Experience.

Objective: To test whether the association between flavor at first vape and continued use is mediated through subjective experience at first vape.

Study Design: In a 2020 cross-sectional survey, 955 young adult ever-vapers recalled their first flavor vaped, subjective experiences at first use, current vaping behavior, nicotine dependence, and quit attempts. A latent class model grouped first-use subjective experiences into classes.

Effects of exposure to snus marketing with versus without modified risk tobacco product claims on snus use intention and perceived harm among young adults.

Background: We tested whether snus marketing with modified risk tobacco product (MRTP) claims: (a) promotes accurate knowledge about snus's health effects in young adults and (b) encourages use intentions in only those who use combustible tobacco without attracting other young adult populations.

Methods: A randomised between-subjects experiment was embedded in a 2020 web survey of participants from Los Angeles (aged 19-23 years). Participants viewed mass-marketed snus advertising materials with (n=1212) vs without (n=1225) US Food and Drug Administration-authorised MRTP claims.

Effect of Substitutional Metallic Impurities on the Optical Absorption Properties of TiO.

(TiO) is both a natural and artificial compound that is transparent under visible and near-infrared light. However, it could be prepared with other metals, substituting for Ti, thus changing its properties. In this article, we present density functional theory calculations for TiAO, where A stands for any of the eight following neutral substitutional impurities, Fe, Ni, Co, Pd, Pt, Cu, Ag and Au, based on the rutile structure of pristine TiO.

Alcohol Use and Life Stressors During the COVID-19 Pandemic: A Longitudinal Study of Young Adults.

Objective: To estimate the extent to which drinking to cope with the COVID-19 pandemic and experiencing pandemic-related life stressors are associated with alcohol use escalation among young adults.

Methods: Respondents in Los Angeles, CA, USA (N=2,130) completed prospective cohort study surveys before (baseline; October 2018-November 2019; mean age: 19.7[SD=0.

Modelling solar photovoltaic systems on dairy farms for cost savings and GHG emission reduction.

Rising on-farm electricity demand, coupled with surges in electricity prices, has increased costs associated with milk production. Additionally, the use of grid electricity with a high carbon footprint depreciates the environmental performance of dairy farming. We assessed the potential of photovoltaic (PV) systems installed on dairy parlours under different policy incentives to reduce electricity costs and the carbon footprint of dairy farms in Ireland.

Emotion Regulation Moderates Associations between Discrimination and Cannabis Use Patterns among Sexual Minority Young Adult Women.

In this cross-sectional survey study, AYAs aged 13-26 (=1,163) reported current NTP use, SM use frequency, and exposure to and engagement with SM content promoting and opposing NTP use (i.e.

Single amino acid change in tomato brown rugose fruit virus breaks virus-specific resistance in new resistant tomato cultivar.

Introduction: Tomato cultivation across the world is severely affected by emerging plant viruses. An effective method for protection of commercial crops against viral threats is the use of cultivars harboring resistance genes. Tomato brown rugose fruit virus (ToBRFV), a recently emerged tobamovirus, is able to overcome the dominant resistance that is present in the majority of commercial tomato cultivars.

Role of STIM1 in stretch-induced signaling in human airway smooth muscle.

Alteration in the normal mechanical forces of breathing can contribute to changes in contractility and remodeling characteristic of airway diseases, but the mechanisms that mediate these effects in airway cells are still under investigation. Airway smooth muscle (ASM) cells contribute to both contractility and extracellular matrix (ECM) remodeling. In this study, we explored ASM mechanisms activated by mechanical stretch, focusing on mechanosensitive piezo channels and the key Ca regulatory protein stromal interaction molecule 1 (STIM1).

US adolescents' response to nicotine warning labels in influencer e-cigarette marketing social media posts: a survey-based randomised between-subject experiment.
