Uncertainty maps provide a quantitative and visual representation of the estimated confidence of Deep Learning (DL) models in contouring predictions and have been proposed to improve clinicians’ efficiency during manual review. However, uncertainty maps are not currently integrated into clinical workflows, and evidence on their actual benefit in clinical decision-making remains limited. This study

Converting conventional cropping systems from annual to perennial has been proposed as a strategy to enhance soil organic carbon (SOC) input and storage due to larger root systems and reduced soil disturbance. The mechanisms underlying SOC sequestration are fundamentally mediated by soil microorganisms, which play dual roles: they assimilate labile plant-derived C into microbial biomass that can s

Microbial communities play a fundamental role in lake nutrient cycling, yet their composition and functional diversity in response to environmental gradients remain poorly understood. Specifically, little is known about how the supply of dissolved macronutrients, including inorganic and bioavailable organic fractions, shape microbial community structure, and functional diversity in lakes that are

Glucose‑dependent insulinotropic polypeptide (GIP) and glucagon‑like peptide‑1 (GLP‑1) regulate metabolism and are increasingly targeted in therapies for type 2 diabetes and obesity. Although GLP‑1 receptor agonists confer cardiovascular benefits, the cardiovascular effects of GIP receptor (GIPR) stimulation remain controversial. This study aimed at defining the short-term cardiovascular consequen

Dynamic functional connectivity (dFC) captures temporal dynamics in functional magnetic resonance imaging (fMRI) to better characterize brain activity, supporting multiple downstream analyses. However, effective modeling strategies for extracting representative signals from dFC remain underexplored. We proposed a novel Subject-wise and Temporal Contrastive Transformer (STCT) framework that advance

BACKGROUND CONTEXT: Low vitamin D levels in individuals with idiopathic scoliosis (IS) have been reported and suggested as a potential contributor to IS. Bone density has also been shown to be lower in individuals with IS. PURPOSE: To investigate serum levels of vitamin D, parathyroid hormone (PTH), markers of bone metabolism, and the genetic variation associated with vitamin D levels and bone den

The vehicle routing problem is one of the most often studied optimization problems. In this study, an improved artificial bee colony (ABC) algorithm is proposed which is structured specifically to address the capacitated vehicle routing problem (CVRP), a significant challenge in combinatorial optimization. The proposed algorithm integrates several novel features to improve its performance on CVRP

Electrification of regional railway systems constitutes a promising strategy for reducing greenhouse gas (GHG) emissions and improving air quality in the transportation sector. While full electrification via overhead line equipment (OLE) is technically viable for high-density corridors, it is often not economically justified on low-traffic routes due to high infrastructure costs relative to usage

Efficient energy management is a key challenge for regional train services,especially when considering the seasonal variation in auxiliary energy demands such as heating, ventilation, and air conditioning (HVAC). This studyexplores how adjusting the maximum operational speed of regional trains canoptimize energy consumption without exceeding design limits or necessitating larger battery sizes. By

BACKGROUND AND PURPOSE: Interphalangeal joint arthrodesis of the hand is a common procedure, but data on outcomes and complications is limited. We aimed to determine the non-union rate, evaluate risk factors for non-union, and investigate the frequency and distribution of complications across different fixation methods.METHODS: We retrospectively reviewed all interphalangeal joint arthrodeses perf
