X-Ray Emission of Nearby Low-mass and Sunlike Stars with Directly Imageable Habitable Zones

The Astrophysical Journal Supplement Series
Stellar X-ray and UV radiation can significantly affect the survival, composition, and long-term evolution of the atmospheres of planets in or near their host star’s habitable zone (HZ).

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Updated EAACI Statement on Drug Hypersensitivity Skin Testing: Methodology and Non‐Irritative Concentrations

Allergy, EarlyView.
ABSTRACT These updated EAACI guidelines aim to standardize skin testing methodologies for both immediate and non‐immediate drug hypersensitivity reactions. For immediate reactions, the optimal testing window is 4–6 weeks post‐reaction; whereas beyond 6 months, false‐negative results increase.

The properties of discrete X-ray sources in star-forming galaxies [PDF]

, 2012
Observations of starburst galaxies have revealed a large number of point-like X-ray sources located within these systems, including active galactic nuclei (AGN), X-ray binaries (XRBs), and utraluminous X-ray sources (ULXs).

Darier disease—A review highlighting new insights from the Darier Disease International Task Force

Journal of the European Academy of Dermatology and Venereology, EarlyView.
This review provides a global, clinically focused overview of DD, detailing cutaneous and extracutaneous manifestations, disease classification and severity scoring. It emphasizes early recognition, multidisciplinary management and practical guidance for dermatologists to apply evidence‐based care in diverse skin phototypes. Abstract Darier disease (DD)

X-ray-selected broad absorption line quasi-stellar objects

, 2016
We study a sample of six X-ray-selected broad absorption line (BAL) quasi-stellar objects (QSOs) from the XMM–Newton Wide Angle Survey. All six objects are classified as BALQSOs using the classic balnicity index, and together they form the largest sample

Photochemical effects of Mars‐like UV irradiation on carboxylic acids in carbonaceous chondrites and expectations for abiotic background organics on Mars

Meteoritics &Planetary Science, EarlyView.
Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

BeppoSAX-WFC catalog of fast X-ray transients

Astronomy & Astrophysics
We performed a search for fast X-ray transients (FXTs), defined for the purposes of this work as transients with durations of longer than one second and shorter than one day. We used data from the Wide Field Camera (WFC) instrument on board the Beppo SAX
