Examining the between‐ and within‐person associations among perceived sleep quality and mental health symptoms in emergency medical service clinicians

open access: yesJournal of Traumatic Stress, EarlyView.
Abstract Disturbed sleep is a known risk factor for heightened mental health symptoms, and this association may be particularly problematic among emergency medical service (EMS) clinicians. Yet, associations between daily sleep quality and daily mental health symptoms are understudied among this vulnerable group.

Dynamics of Thermally Induced Phase Separation in Polyvinyl Alcohol Aqueous Solutions: Impact of Viscosity Asymmetry on Scaling

open access: yesMacromolecular Chemistry and Physics, EarlyView.
The dynamics of thermally induced phase separation in polyvinyl alcohol (PVA) solutions are investigated using laser scanning confocal microscopy. Despite a large viscosity difference of nearly 1000 between separated phases, critical and off‐critical mixtures exhibit distinct morphologies while both maintain self‐similar growth patterns, challenging ...

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Direct Ambient Mass Spectrometry for Food, Beverage, and Agricultural Sample Analysis and Research

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Ambient and direct mass spectrometry (MS) methods are becoming increasingly used for the rapid analysis of food, beverage and agricultural samples. Novel ionization approaches combined with targeted, or untargeted workflows provide analytical outcomes within a greatly reduced time period compared to traditional separation science coupled with ...

Neural Mechanisms of Object Location Memory in Huntington's Disease

open access: yesMovement Disorders, EarlyView.
ABSTRACT Background Object‐location memory impairment in Huntington's disease (HD) occurs from premanifest period and declines as HD progresses, however, pathogenesis of object‐location memory is unknown. The striatum and hippocampus are affected in HD, functionally interacting allowing intact object‐location memory.

A Systematic Review of Empirical Studies on Situation Awareness: Perspectives From the Interaction Among Humans, Machines, and the Task Environment

open access: yesPsyCh Journal, EarlyView.
ABSTRACT Situational awareness (SA) refers to “knowing what is going on” in a situation. As an essential concept originating in aviation literature approximately 40 years ago, SA has demonstrated significant potential and has since been extended across various fields, leading to a growing body of research.

Hybrid Nanoparticles Separated by Buoyant Density in a Large‐Scale Centrifugal Process

open access: yesJournal of Polymer Science, EarlyView.
Zonal rotors, shaped like hollow bowls, can sort mixtures of macromolecules and polymer nanoparticles based only on their densities, regardless of their actual sizes or shapes. Using these rotors can make a big difference because they do not need to use centrifuge tubes.
