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

The 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 ...

Treatment of a Large Cohort of Childhood Chronic Noninfectious Uveitis in a Multicentric Large Study: Adalimumab Versus Methotrexate as First‐Line Therapy

Arthritis &Rheumatology, EarlyView.
Objective Treatment of childhood chronic idiopathic uveitis (cCIU) is predominantly based on studies in juvenile idiopathic arthritis–associated uveitis and expert opinion. Our aim was to report the treatment outcomes of our cohort of cCIU. Methods Retrospective multicenter study involving the rheumatology and ophthalmology units at Florence, Italy ...

Double Tidal Disruption Events or Repeating Partial Tidal Disruption Events in AT 2020vdq

The Astrophysical Journal
AT 2020vdq has been known as a candidate of repeating partial tidal disruption events (pTDEs) due to its two flares with a time interval of ∼1000 days.

A multifaceted interplay between hemophagocytosis, IL‐18 and type I IFN distinguishes Still disease from other autoinflammatory diseases

Arthritis &Rheumatology, Accepted Article.
Objectives The unknown pathophysiology and the lack of specific features for systemic Juvenile Idiopathic arthritis and adult‐onset Still disease (collectively Still disease/SD) delays diagnosis and appropriate treatment. The goal of this study was to identify features and mechanisms that distinguish SD from other systemic autoinflammatory diseases ...

Repeating Nuclear Transients From Repeating Partial Tidal Disruption Events

Astronomische Nachrichten, EarlyView.
ABSTRACT Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A subset of these transients, with recurrence timescales of months‐to‐years, have been explained as accretion flares from the repeated tidal stripping of a star by an ...

Statistical Study of the Timing of the Appearance of Hα Postflare Loops: Simple Scaling Law Based on Radiative Cooling

The Astrophysical Journal
Recent Sun-as-a-star studies have shown that postflare loops can manifest as a secondary peak in the H α light curve, suggesting that stellar postflare loops are detectable.

Pharmacokinetics, safety, tolerability and fluorescence imaging of nizaracianine triflutate administered in three divided doses to healthy volunteers

British Journal of Clinical Pharmacology, EarlyView.
Aim Fluorescence‐guided surgery enhances intraoperative visualization of anatomical structures. Nizaracianine is a near‐infrared fluorescent agent that is exclusively renally cleared in animal models. It enables real‐time ureteral imaging and identification, potentially reduces risk of injury and facilitates assessment before surgical closure.

‘Where are the adults?’: Troubling child‐activism and children's political participation

British Educational Research Journal, EarlyView.
Abstract Children's political participation is a well‐established theme in childhood studies. In this article we offer an original account of child activism that takes into account the entangled and emergent aspect of children as activists. We begin with a historical and a conceptual review, noting the importance of mid‐20th century developments such ...

Potential Chromospheric Evaporation in the M Dwarf’s Flare Triggered by Einstein Probe Mission

The Astronomical Journal
Although flares from late-type main-sequence stars have been frequently detected in the multiwavelength, the associated dynamical process has been rarely reported so far.
