Fulminic acid: a quasibent spectacle.

Fulminic acid (HCNO) played a critical role in the early development of organic chemistry, and chemists have sought to discern the structure and characteristics of this molecule and its isomers for over 200 years. The mercurial nature of the extremely flat H-C-N bending potential of fulminic acid, with a nearly vanishing harmonic vibrational frequency at linearity, remains enigmatic and refractory to electronic structure theory, as dramatic variation with both orbital basis set and electron correlation method is witnessed. To solve this problem using rigorous electronic wavefunction methods, we have employed focal point analyses (FPA) to ascertain the limit of optimized linear and bent geometries, corresponding vibrational frequencies, and the HCN + O() → HCNO reaction energy.

Ethynyl Radical Hydrogen Abstraction Energetics and Kinetics Utilizing High-Level Theory.

The ethynyl radical, CH, is found in a variety of different environments ranging from interstellar space and planetary atmospheres to playing an important role in the combustion of various alkynes under fuel-rich conditions. Hydrogen-atom abstraction reactions are common for the ethynyl radical in these contrasting environments. In this study, the CH + HX → CH + X, where HX = HNCO, -HONO, -HONO, CH, and CHOH, reactions have been investigated at rigorously high levels of theory, including CCSD(T)-F12a/cc-pVTZ-F12.

Glucagon-Like Peptide Receptor Agonists Use Before Endoscopy Is Associated With Low Retained Gastric Contents: A Multicenter Cross-Sectional Analysis.

Introduction: While ubiquity of glucagon-like peptide receptor agonists (GLP1-RAs) is rising, guidance from the gastroenterology societies and American Society of Anesthesiologist (ASA) remains in conflict on recommendations regarding preoperative holding before endoscopy. The aim of this study was to address this by evaluating the effect of GLP1-RAs on gastric retention during upper endoscopy.

Methods: This multicenter cross-sectional study included patients on confirmed GLP1-RAs receiving an endoscopy from 2021 to 2023.

Comparing the healthy development of youth Australian Rules Footballers across talent development and community settings.

Objectives: This study aimed to compare talent development athletes to community-level athletes in Australian Rules Football across various markers of healthy youth development.

Methods: Survey data were collected from 363 youth athletes (126 women, 232 men, 5 not reported; Mage=18.69 years, SDage=2.

People with Inflammatory Bowel Disease Prefer Cognitive Behavioral Therapy for Fatigue Management: A Conjoint Analysis.

Background: Psychological interventions are a promising area for fatigue management in patients with inflammatory bowel disease (IBD). However, most interventions trialled to date have been pilots with limited direct input from patients about the type of intervention they want. Thus, this study aimed to explore patient preferences for a psychological IBD fatigue intervention.
