The effect of proximity of COVID-19 test facilities on test uptake: two quasi-experimental trials
Access to testing sites is a critical component in reducing the spread of a virus during infectious disease outbreaks. For example, distance to the testing site has been mentioned as an important self-reported barrier for test uptake during the COVID-19 pandemic. Despite its impo...

Abstract This paper contains a proof of a recent conjecture of Artemev that connected the resonance transformations for the $$(2,2p+1)$$ ( 2 , 2 p + 1 ) minimal string to the $$x-y$$ x - y swap in the theory of topological recursion.

During intergroup confrontations, agitating stimuli such as opponents’ threats and provocations can trigger collective violence, even without the usual mechanisms of ingroup cooperation, such as norms with sanctions. We examine video recordings of street fights between groups of...

Time-dependent prognostic value of coronary plaque burden and hyperemic myocardial blood flow
Abstract Rationale The time-dependent contributions of coronary atherosclerotic plaque burden and myocardial ischemia to clinical outcomes in suspected coronary artery disease (CAD) remain uncertain. This study aimed to evaluate the temporal associations of quantitatively assesse...

Abstract Purpose In this study we focused on gaining better interpretation of the PROMIS-Upper-Extremity v2.0 (PROMIS-UE v2.0) T-score scale for measuring upper extremity function in patients with upper extremity injuries (UEIs). This is fundamental in order to clearly understand...

As generative AI makes it easier to create synthetic visuals, AI-driven visual disinformation isbecoming more common on social media. However, while much research highlights its potentialharm, less is known about how to reduce its potential to mislead. In this study, we therefore...

Clinical trials report no increased malignancy risk with benralizumab in severe asthma; however, trial populations are highly selective. To better define real-world safety, malignancy risk was compared among patients treated with benralizumab, other (non-benralizumab) biologics,...

In 94 hospitalised patients with cellulitis, HRQoL was markedly impaired at admission and remained significantly below population norms at 90 days, particularly in patients with persistent pain and oedema. These findings highlight the need for post-discharge follow-up focused on...

BACKGROUND: Children with sickle cell disease (SCD) suffer from vaso-occlusive crises, extremely painful episodes that may require hospitalization. Traumatic experiences during hospitalization and frequent pain experiences may lead to psychological distress and the development of...

Null fluid/gravity correspondence
A bstract We construct a new class of perturbative asymptotically Anti-de Sitter pp-wave spacetimes by performing a long-wavelength expansion of Kaigorodov metrics in arbitrary spacetime dimensions. Holographically, these spacetimes are described by a null fluid hydrodynamic expa...

Norms are fundamental to social life, but basic questions about how they are affected by social context remain. Specifically, how do normative constraints depend on the presence and status of observers, and how do such relational contingencies vary across cultures? Using data fro...

Deep learning aging marker from retinal images unveils sex-specific clinical and genetic signatures
Abstract Retinal fundus images offer a non-invasive window into systemic aging. Here, we fine-tune a foundation model (RETFound) to predict chronological age from color fundus images in 71,343 participants from the UK Biobank, achieving a mean absolute error of 2.85 years. The re...

Abstract Aims/hypothesis Nearly 40% of African adults with type 2 diabetes are lean (BMI <25 kg/m 2 ). Emerging evidence suggests that type 2 diabetes in African individuals who are lean may represent a distinct phenotype driven by impaired insulin secretion rather than insulin r...

Risk Theory in a Finite Customer-Pool Setting
This paper investigates an insurance model with a finite number of major clients and a large number of small clients, where the dynamics of the latter group are modeled by a spectrally positive Levy process. We begin by analyzing this general model, in which the inter-arrival tim...

Abstract Topic Esophageal Cancer: Surgical Treatment of Esophageal Cancer Background Standardization of thoracic duct (TD) management during esophageal cancer surgery remains controversial. TD resection has been hypothesized to enhance oncologic radicality, since it may increase...

In this multi-informant longitudinal study, we examined whether children with higher levels of self-reported sensory processing sensitivity (SPS) showed stronger longitudinal associations between peer relationships (i.e., peer acceptance and rejection) and their social-emotional...
