Atomistic Modeling of Methyl Formate and Glycolaldehyde Formation on Interstellar Dirty Ice Mantles via a “Radical + Ice” Mechanism

open access: yesChemPlusChem, EarlyView.
The presence of interstellar complex organic molecules (COMs) has been baffling astrochemists for a long time. Methyl formate and glycolaldehyde are widely detected but their abundances mismatch kinetic astrochemical model predictions. Here, the formation of these two COMs is characterized onto a mixed ice surface, highlighting the importance of ...

European Journal of Heart Failure consensus statement. Heart failure pharmacotherapy for patients with heart failure with reduced ejection fraction and concomitant atrial fibrillation: Review of evidence and call to action

open access: yesEuropean Journal of Heart Failure, EarlyView.
Heart failure (HF) and atrial fibrillation (AF) are major global health challenges with rising prevalence and significant morbidity, mortality, and healthcare burden. Despite advances in HF management, AF remains a critical comorbidity that worsens outcomes and requires ad hoc treatment strategies, increasing the risk of non‐adherence and side effects.

A Fast Radio Burst in a Compact Galaxy Group at z ∼ 1

open access: yesThe Astrophysical Journal Letters
FRB 20220610A is a high-redshift fast radio burst (FRB) that has not been observed to repeat. Here, we present rest-frame UV and optical Hubble Space Telescope observations of the field of FRB 20220610A. The imaging reveals seven extended sources, one of

Adverse Outcome Pathways Applied to Space Radiation Research

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
ABSTRACT Long‐duration spaceflight exposes astronauts to various stressors that can alter human physiology, potentially causing immediate and long‐term health effects. These stressors can damage biomolecules, cells, tissues, and organs, leading to adverse outcomes.

Shelf‐Life Enhancement of Sugarcane Juice With Herbal Extracts: Extracted Through Novel Microwave‐Assisted Drying Extraction Technique

open access: yesFood Safety and Health, EarlyView.
ABSTRACT Antioxidants in foods delay or prevent the oxidation of the food. Previously, synthetic antioxidants were commonly used in food formulations, but, due to safety concerns, interest in natural antioxidants has intensified. A novel microwave‐assisted drying extraction process was adopted to dry mint and coriander leaves.

Discovery of Giant Bubbles in the Hot Gaseous Halo of the Massive Disk Galaxy NGC 6286

open access: yesThe Astrophysical Journal
Based on archival Chandra X-ray observation, optical integral-field spectroscopic data, and radio interferometric data, we report the discovery of a pair of giant bubbles (with a projected radius ∼5 kpc) of ionized gas emerging from a highly inclined ...

On the characteristics of tidal structures of interacting galaxies

open access: yes, 2011
We present the results of our analysis of the geometrical tidal tail characteristics for nearby and distant interacting galaxies. The sample includes more than two hundred nearby galaxies and about seven hundred distant ones.
