Association of the IceCube neutrinos with CAZ blazar light curves

Astronomy & Astrophysics
The IceCube Neutrino Observatory has detected several hundred high-energy neutrinos from cosmic sources. Despite numerous studies searching for their origin, it is still not known which sources emit them.

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 ...

Sub-second cadence structure of optical flares on AD Leo

Astronomy & Astrophysics
Context. Stellar flares are sudden brightenings caused by magnetic reconnection and are frequently observed on late-type stars. High-cadence photometry of flares provides valuable insights into the mechanisms of these events, yet such observations remain

Threshold Currents of Vacuum Arcs With Tungsten and Copper Cathodes

High Voltage, EarlyView.
ABSTRACT This paper presents the results of an experimental study aimed at determining the threshold current for triggering a vacuum arc discharge, the probability of arc ignition and the average arc operation time depending on the current for tungsten and copper electrodes.

The Proxima Centauri Campaign—First Constraints on Millimeter Flare Rates from ALMA

The Astrophysical Journal
Proxima Centauri (Cen) has been the subject of many flaring studies due to its proximity and potential to host habitable planets. The discovery of millimeter flares from this M dwarf with Atacama Large Millimeter/submillimeter Array (ALMA) has opened a ...

Characterization of Prurigo Nodules in Adults With Moderate‐To‐Severe Atopic Dermatitis in Japan: A 2‐Year Observational Study

The Journal of Dermatology, EarlyView.
ABSTRACT Clinical phenotypes of atopic dermatitis (AD) can vary, with some individuals displaying difficult‐to‐treat prurigo nodularis‐like lesions. We aimed to assess the real‐world disease burden and treatment course of Japanese adults with AD‐associated prurigo nodules (AD‐Pn) receiving conventional AD treatments.

Prey group cohesion mediates the outcome of predator–prey interactions under artificial lighting

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The highest rates of piscivorous predation in the field have been recorded during crepuscular light levels associated with sunrise and sunset or artificial lighting at night (ALAN).

VISUAL NEGOTIATIONS OF GENTRIFICATION IN TORONTO: Contestation, Politicization and Resistance through Urban Signage

International Journal of Urban and Regional Research, EarlyView.
Abstract This article engages signage as a medium through which urban stakeholders negotiate the politics of housing redevelopment and gentrification in cities. Focusing on Toronto, we examine housing‐related signage in three neighbourhoods where social mix approaches to redevelopment have ushered in gentrification: Parkdale, Regent Park, and Moss Park.
