Hydrogen Sensing via Heterolytic H2 Activation at Room Temperature by Atomic Layer Deposited Ceria.

Ultrathin atomic layer deposited ceria films (< 20 nm) are capable of H2 heterolytic activation at room temperature, undergoing a significant reduction regardless of the absolute pressure, as measured under in-situ conditions by near ambient pressure X-ray photoelectron spectroscopy. ALD-ceria can gradually reduce as a function of H2 concentration under H2/O2 environments, especially for diluted mixtures below 10%. At room temperature, this reduction is limited to the surface region, where the hydroxylation of the ceria surface induces a charge transfer towards the ceria matrix, reducing Ce4+ cations to Ce3+.

Chronic Cough and Hyperpnea: Clinical Approach to Equine Asthma.

Exercise intolerance, chronic cough, and hyperpnea are the clinical hallmarks of equine asthma. Diagnosis of severe equine asthma in horses is multistep; determination of the phenotype will help guide future recommendations. Management of equine asthma is largely reduction/elimination of triggering agents/conditions.

Demographics, Epidemiology, Mortality, and Difficult-To-Treat Resistance Patterns of Bacterial Bloodstream Infections in the Global United States Military Health System from 2010-2019: A Retrospective Cohort Study.

Objective: To describe demographics, causative pathogens, hospitalization, mortality, and antimicrobial resistance of bacterial bloodstream infections (BSIs) among beneficiaries in the global U.S. Military Health System (MHS), a single-provider healthcare system with 10-year longitudinal follow-up.

Land Use Change Consistently Reduces α- But Not β- and γ-Diversity of Bees.

Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α-diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e.

Differences on lower trapezius pressure pain threshold, muscle strength and muscle thickness in individuals with chronic neck pain and active or latent myofascial triggers points.

Background: Myofascial trigger points (MTrPs) in the lower trapezius have been recognized as an important source of neck pain. This study aims to compare the lower trapezius muscle strength, pressure pain threshold (PPT) and muscle thickness at rest and contraction between participants and painful vs. no-painful side with active and latent MTrPs; and to examine the associations among these variables with pain intensity, duration and disability in patients with neck pain.
