The Impact of Stellar Flares on the Atmospheric Escape of Exoplanets Orbiting M Stars. I. Insights from the AU Mic System

open access: yesThe Astrophysical Journal
The X-ray and extreme ultraviolet (XUV) emission from M stars can drive the atmospheric escape on planets orbiting them. M stars are also known for their frequent emission of stellar flares, which will increase the high-energy flux received by their ...

A Large Retrospective Study to Evaluate Utility of Zephyr Covered Stent in Transcatheter Closure of Sinus Venosus Defects

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter closure (TCC) of sinus venosus defects (SVD) using balloon‐expandable covered stents is an emerging alternative to surgery. ZephyrCS (Sahajanand Laser Technologies, Gandhinagar, India) is available in long lengths to suit SVD closure.

Stellar Flares and Coronal Structure

open access: yes, 2003
Coronal structure and coronal heating are intimately related in magnetically active stars. Coronal structure is commonly inferred from radio interferometry and from eclipse and rotational modulation studies. We discuss to what extent flares may be responsible for coronal structure and global observable properties in magnetically active stars.

A novel bubbling fluid bed reactor for the autothermal pyrolysis of waste plastics

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract A new pilot‐scale fluidized bed reactor operated under continuous conditions was developed and tested for the thermal pyrolysis of high‐density polyethylene (HDPE). The study focused on assessing the reliability and operability of the system under different operating conditions (400–550°C), while monitoring mass and energy balances, product ...

Clinical Model‐Informed Precision Dosing Consult Service for Accelerating Personalized Medication in Pediatric Patients

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Traditional dosing strategies often rely on a “one‐size‐fits‐all” paradigm, assuming an “average” patient with typical demographic and pharmacological characteristics. In reality, this often overlooks existing between‐patient variability and can lead to suboptimal drug exposure or toxicity. This issue is especially pronounced in pediatric patients, who

Molten‐Salt‐Mediated Chemical Looping Oxidative Dehydrogenation of Ethane with In‐Situ Carbon Capture and Utilization

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
A sustainable alternative to steam cracking, the molten‐salt‐mediated oxidative dehydrogenation (MM‐ODH) of ethane (C2H6) in Li2CO3‐Na2CO3‐K2CO3 (LNK) couples thermal cracking with melt‐mediated CO2 capture to realize commercially competitive C2H4 and CO yields. LNK composition strongly influences MM‐ODH process outcomes.

Review of articular cartilage repair techniques and their application in the horse

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Articular cartilage lesions represent a significant career‐limiting problem in athletic horses. A healthy articular cartilage surface is vital for optimal joint function, and defects can result in irreversible degenerative changes. Successful treatment of cartilage lesions remains a long‐standing challenge for orthopaedic surgeons, prompting ...

Food Contamination and Safety in Nigeria: A Systematic Synthesis of Heavy Metals, Microbial Pathogens, and Health Risk Metrics

open access: yesFood Safety and Health, EarlyView.
This is an infographic driver of food contaminants and health effects. ABSTRACT Food safety remains a critical challenge in Nigeria due to rapid urbanization and weak regulatory enforcement. This systematic review synthesizes empirical evidence from 2015 to 2025 to characterize food contaminant profiles and associated human health risks in Nigeria ...
