Purpose: To evaluate a new analytical estimator for R1 and apparent proton density (𝐴) from short-TR dual flip angle data which does not rely on the small flip angle approximation and can thus be applied to a broader range of data, especially where relatively large flip angles are needed to achieve sufficient T1-weighting for R1 estimation.Theory and Methods: A rational approximation of the Ernst

BACKGROUND: Minimally invasive surgery is rapidly expanding globally, yet there is insufficient knowledge of how to scale this technology safely and equitably across diverse health systems. We aimed to identify health-system factors associated with safe implementation of minimally invasive surgery globally, using minimally invasive cholecystectomy as a tracer procedure.METHODS: We conducted a mult

This presentation offers an outline of classical modern reflection (sociology, cultural theory, literature) on the constitution and transformation of modernity, its cultural and mental dispositions. The discussion focuses on key themes and experiences of classical modernity: void, crisis and abundance. It is argued that classical modernity may be conceived as a conceptual archive of influential id

Purpose: The aim of this study was to evaluate the feasibility and mid-term results of combining polytetrafluoroethylene (PTFE)-based iliac limbs, having a short dilator tip, with a polyester (Dacron)-based bifurcated component during a fenestrated endovascular aortic repair (FEVAR).Materials and methods: All patients who underwent a FEVAR procedure in a single tertiary center were screened for in

Chickenpox is a highly contagious viral infection caused by varicella-zoster virus (VZV) whose clinical manifestations mimic mpox posing challenges for diagnosis without laboratory confirmation. Here, we investigated VZV among the mpox-suspected cases, May to October 2022, in Ethiopia. Samples were collected from 202 mpox-suspected cases in 11 of Ethiopia’s 14 regions and screened for mpox virus b

Para Alpine skiing is one of the largest sports at the Paralympic Winter Games. Recent studies report high injury rates in this sport. However, limited evidence exists regarding sport-specific injury characteristics, which is essential for targeted prevention. The aim of this study was to describe the overall incidence proportion and incidence of injuries reported by athletes participating in Alpi

Major depressive disorder (MDD) has been linked to altered brain networks and might be relieved by music therapy. Yet, the neurophysiological basis, especially the functional network mechanism, of music therapy on depression remains poorly understood. Here, we apply a novel dynamic module detection method based on block term decomposition (BTD) to examine the reorganization of time-varying topolog

Smoking is widely regarded as a risk factor for type 2 diabetes because nicotine contributes to insulin resistance by desensitizing the insulin receptors in muscle, liver, or fat. Little is known, however, about the immediate regulation of islet hormonal output by nicotine, an agonist of ionotropic cholinergic receptors. We investigated this by imaging cytosolic Ca2+ dynamics in mouse and human is

Privacy-preserving blueprint schemes (Kohlweiss et al., EUROCRYPT’23) offer a mechanism for safeguarding user’s privacy while allowing for specific legitimate controls by a designated auditor agent. These schemes enable users to create escrows encrypting the result of evaluating a function y=P(t,x), with P being publicly known, t a secret used during the auditor’s key generation, and x the user’s

Several studies have demonstrated strong agreement between routine clinical visual assessment and quantification, suggesting that quantification approaches could support assessment by less experienced readers or in challenging cases. However, all studies to date have implemented a retrospective case collection, and challenging cases were generally underrepresented. Methods: We included all partici

Background: Inadequate health literacy increases medical costs and leads to poor health outcomes. However, there is a paucity of empirical evidence of such associations in sub-Saharan Africa. This study investigates how the household cost of malaria in children under five in Ghana varies based on different levels of health literacy. Methods: A cross-sectional survey involving 1270 caregivers of ch

The purpose of this study is to investigate tourists’ behavioral intentions when selecting LHA for stays, considering the effects of the Attitude-Social Influence‑Efficacy Model, social identity theory, and accommodation attributes to predict guest behavior Applying a quantitative research design, questionnaire survey, and structural equation modeling for analyzing the data, the results revealed t

This paper studies how national welfare-state institutions influenced the positions states took on the social rights of refugees during the negotiation, adoption, and ratification of the 1951 United Nations Convention Relating to the Status of Refugees. Through an analysis of the drafting process and the reservations and interpretative declarations states issued when rat-ifying the Convention, the

Minimal Kitaev chains, composed of two quantum dots connected via a superconductor, have emerged as an attractive platform to realize Majorana bound states (MBSs). These excitations exist when the ground state is degenerate. The additional requirement of isolating the MBS wave functions further restricts the parameter space to discrete sweet spots. While scaling up to Kitaev chains with more than

The coherence factors of quasiparticles in a superconductor determine their properties, including transport as well as their susceptibility to electric fields. In this work, we propose a way to infer the local coherence factors using local transport to normal leads. Our method is based on measuring the local current through a lead as the coupling to a second one is varied; the shape of the current

Rochechouart, south-west France, is a complex impact structure. Here, we present the first report of shock barometry of quartz from what are likely parautochthonous basement units at depth, based on samples from the 2017 C.I.R.I.R drilling campaign. The crystallographic orientations of 725 sets of PDFs in 512 quartz grains in samples from four drill cores were measured. We find basal PDFs (Brazil

Context: Chronic dyspnea is subjective but with objective (measurable) consequences. It is often poorly assessed because people have modified their lifestyles to avoid exertion that generates dyspnea. Objectives: This study sought any relationship between respondents’ self-reported long-term breathlessness limiting exertion (hereafter chronic dyspnea) and distance travelled from the room in which
