Proposals that gesture played a pivotal role in the evolution of language have been highly influential. However, there are many differences between gestural origin theories, including different definitions of 'gesture' itself. We use a cognitive semiotic approach in order to categorize and review these theories. A semiotic system is a combination of signs or signals of particular type, defined by

2023 JCP Emerging Investigators Special Collection: Tuning perovskite nanocrystal superlattices for superradiance in the presence of disorder

Background: Dyspnea is a common and diagnostically challenging symptom in the emergency department (ED), particularly among older adults with multimorbidity. Traditional risk stratification tools often perform poorly in this population. Galectin-3 (Gal-3), a biomarker of inflammation and fibrosis, may reflect biological aging and resilience, potentially improving early mortality risk assessment.Ob

The elastic properties of amorphous TiNiSn, a promising half-Heusler system for flexible and wearable devices, were investigated using experimental and theoretical methods. Nanoindentation measurements performed on amorphous TiNiSn thin film grown by magnetron sputtering yielded an elastic (Young’s) modulus value of 132 GPa. To corroborate this result, density functional theory (DFT) calculations The elastic properties of amorphous TiNiSn, a promising half-Heusler system for flexible and wearable devices, were investigated using experimental and theoretical methods.

BACKGROUND: Peptic gastroduodenal stenosis is a rare but disabling condition causing gastric outlet obstruction. This study aimed to evaluate endoscopic balloon dilation in terms of treatment effectiveness, durability, and identify potential early predictors of unsatisfactory outcomes.METHODS: We conducted a retrospective cohort study of patients who underwent endoscopic balloon dilation for sympt

Particle induced oxidative stress is a probable pathway for many of the detrimental health-effects caused by particulate matter (PM). Recent studies on the exposure to oxidative potential (OP) in ambient fine and coarse PM suggest that anthropogenic particle pollutants, especially vehicular wear, anthropogenic primary and secondary organic aerosols (SOA) are more toxic on mass basis and more relev

Traffic-related air pollution has severe implications for our health and stringent emission legislation is being enforced to traffic emissions, for example in the EU, USA, and China. With stricter emission legislation (next is EURO 7) and a rapid growth of battery electrical vehicles (BEVs) the combustion-derived pollutants emitted from the tailpipe are decreasing. However, heavier vehicles have r

Carbon Black (CB), graphene, and nanodiamonds represent three classes of manufactured carbonaceous nanoparticles consisting almost exclusively of insoluble material. Particle-related Reactive Oxygen Species (ROS) have been linked to in vivo and in vitro toxicity and determining particle ROS activity is an efficient way of estimating nanomaterial toxicity and assist in the safe-by-design developmen
