The neighboring stars of N6946-BH1 and the observational characteristics of failed supernovae
Stellar collapse models predict that some stars more massive than $ 15 M_$ may collapse directly to a black hole, sometimes with a weak optical transient, a phenomenon known as a failed supernova. Detecting such events is challenging, but searches of vanishing stars have found tw...

ASPECTS OF THE SOCIAL LIFE OF THE COMMON PEOPLE IN FATIMID EGYPT (358-567 AH / 969-1171 AD)
This study examines various aspects of the social life of commoners in Fatimid Egypt between 358–567 AH / 969–1171 CE. It seeks to define the "commoners," distinguish them from the elite classes, explore their family structures and interpersonal relationships, examine gender and...

Introduction: Community first responders (CFRs) are integrated within UK ambulance services to deliver early life-saving interventions prior to the arrival of emergency medical services (EMS). Although CFR attendance is associated with earlier cardiopulmonary resuscitation (CPR)...

The line spread function (LSF) of a spectrograph encodes the inherent broadening of a single spectral line. It is typically reported as a single number, the resolving power R = λ / Δ λ with Δ λ the FWHM of the LSF. In standard pipelines for extracting stellar kinematics the LSF i...

Introduction: Cardiopulmonary resuscitation-induced consciousness (CPRIC) is the term commonly used to refer to signs of life displayed by patients during resuscitation. This phenomenon presents a challenge, as these signs of life can interfere with resuscitative efforts. Interna...

Introduction: Teleconsultation is increasingly used within pre-hospital emergency care to provide remote clinical support for paramedics and patients. Despite its growing integration into healthcare systems, there is limited empirical research exploring paramedics’ lived experien...

Purpose: The purpose of this study was to quantify whether fundus tracking in microperimetry improves psychometric parameter estimation (as an in vivo demonstration of improved stimulus-delivery precision), and to derive a psychometrically grounded criterion intensity for suprath...

Open-Source Software Suite for Cell Detection and Segmentation in Adaptive Optics Retinal Imaging
Purpose: The purpose of this study was to present a suite of open-source software tools for automated and interactive annotation (detection and segmentation) of retinal cells from adaptive optics (AO) images. Methods: Three related software packages were developed, implementing m...

Attentional templates in visual working memory (VWM) are essential for guiding visual search. Although much debate has focused on whether these templates are stored in discrete states or continuous resources, a question remains: To what extent can the priority of a template be st...

UV absorption line indices trace both chemical enrichment and star formation histories in high-redshift galaxies, yet their reliability as tracers of stellar metallicity (Z*) remains uncertain. In this study, we combine synthetic spectral modelling and cosmological simulations to...

TDCOSMO XXVI: Uniform Lens Modeling of Eight Doubly Imaged Quasars
We present the first uniform gravitational lens modeling analysis of eight doubly imaged quasars from multi-band observations with the Hubble Space Telescope. Previous time-delay cosmography analyses by the TDCOSMO Collaboration have primarily relied on quadruply imaged quasars,...
