A multimodal deep learning-driven model for assessing drawing composition quality

In recent years, digital art education, computerized evaluation systems, and aesthetic computing have prioritized drawing composition quality assessment. Traditional assessments have relied on subjective judgment or single-modal analysis, limiting scalability and uniformity. Exis...

The Arthroscopic Wafer Procedure Provides Successful Midterm Outcomes for Idiopathic Ulnar Impaction Syndrome: A Minimum 5‐Year Follow‐Up

PURPOSE: To evaluate the midterm clinical and radiologic outcomes of the arthroscopic wafer procedure for idiopathic ulnar impaction syndrome with a minimum 5-year follow-up. METHODS: Patients with idiopathic ulnar impaction syndrome and less than 4 mm of positive ulnar variance...

Projected Primal–Dual Gradient Preference Optimization Under Category-Wise Split-Conformal Safety Constraints for Large Language Model Post-Training

Preference optimisation improves helpfulness, but a single aggregate safety penalty lets frequent harm categories dominate the objective while rare ones bear the residual risk. This paper models post-training as a vector-constrained programme: the pairwise preference loss is mini...

Association of Estimated Arterial Stiffness with Collateral Status and Functional Outcome after Endovascular Thrombectomy: A Secondary Analysis of the OPTIMAL-BP Trial

PURPOSE: Estimated pulse wave velocity (ePWV) is a surrogate of arterial stiffness that may influence stroke outcomes and potentially affect collateral circulation. We examined the association of ePWV with collateral status and 3-month functional outcome after successful endovasc...

Pathways from adverse childhood experiences to parenting competence: the roles of cognitive emotional regulation and social support

These findings suggest that strengthening adaptive CER may be particularly effective for mothers with higher levels of social support. For those with lower levels of social support, the first priority should be enhancing social support to lay the groundwork for emotional regulati...

Information and communication technology innovations and labor hours: A business cycle analysis

Abstract This paper examines the impact of changes in information and communication technologies (ICTs) on skilled and unskilled labor at the business cycle frequency. To achieve this, we construct aggregate hours series for both labor groups using the monthly outgoing rotation g...

RINGSIDE Phase II Study of Varegacestat for Treatment of Desmoid Tumors: A Randomized Dose-Finding Clinical Trial

PURPOSE Desmoid tumors (DTs) are rare, often locally aggressive, connective tissue neoplasms with limited effective treatment options. We evaluated the safety and efficacy of varegacestat, an oral gamma-secretase inhibitor. METHODS RINGSIDE phase II was an open-label, randomized,...

A simplified and clinically applicable prediction model for early identification of bacteremia in febrile patients with solid tumors in the emergency department

Abstract Background Bacteremia is a serious and potentially life-threatening complication in patients with cancer, requiring prompt recognition and early initiation of treatment. However, early identification of bacteremia in febrile cancer patients presenting to the emergency de...

Wafer-scale synthesis of WSe 2 for high-performance p-type top-gated transistors and logic circuits

Two-dimensional (2D) transition metal dichalcogenides (TMDs) offer a promising pathway for next-generation electronics due to their exceptional electrical characteristics at atomically thin thickness. Nevertheless, the realization of high-quality p-type 2D-FETs remains a signific...

From Sprain to End-Stage Osteoarthritis: Why Earlier Intervention in Ankle Cartilage Damage Deserves More Attention

➢ Ankle cartilage damage ranges from osteochondral lesions of the talus to end-stage osteoarthritis. End-stage ankle osteoarthritis has been associated with a health burden comparable with that of major chronic diseases such as congestive heart failure and kidney disease, while p...

RhoA Y42C drives cell plasticity and PD-1-mediated immune evasion of diffuse gastric cancer

Diffuse gastric cancer (DGC) is an aggressive gastric cancer subtype with a poor prognosis. The RHOA Y42C mutation is recurrent in DGC, but its independent oncogenic role is unclear. Next-Generation Sequencing of 431 DGC cases revealed that most RHOA mutations occurred without CD...

Trajectories of Albuminuria and Non‐Albumin Proteinuria After Sequential Addition of Finerenone for Residual Albuminuria Despite Established SGLT2 Inhibitor Therapy in Diabetic Kidney Disease: A Real‐World Cohort Study

ABSTRACT Aims CONFIDENCE evaluated simultaneous initiation of finerenone and an SGLT2 inhibitor (SGLT2i). We examined 12‐month trajectories of albuminuria and non‐albumin proteinuria after finerenone was added to established SGLT2i therapy. Materials and Methods This single‐centr...

Early Mitral Valve Surgery and Survival in Asymptomatic Severe Primary Mitral Regurgitation

Importance The optimal timing of mitral valve (MV) surgery in patients with asymptomatic severe primary mitral regurgitation (MR) remains uncertain because randomized clinical trials are lacking. Objective To evaluate the association of early MV surgery with long-term survival in...

Cost-effectiveness of 5.0 μm inline intravenous filtration in surgical inpatients using a decision tree and Markov model

Phlebitis is a common complication of intravenous (IV) therapy, especially in vulnerable populations such as surgical inpatients. Despite being frequently overlooked due to its typically mild presentation, phlebitis may lead to severe complications in high-risk patients. This stu...

Surface Locomotion of Cell‐Sized Microrobots Subject to Adhesive Heterogeneity

Chemically powered microrobots provide a promising route toward untethered operation at small length scales, but their motion near surfaces is often difficult to predict because it depends strongly on both particle design and the local interfacial environment. Here, we investigat...

Hybridization of cobalt oxide with holey 2D niobium nitride nanosheets to promote oxygen evolution reaction

Abstract The control of defect structure and holey morphology has garnered increasing interest owing to its usefulness in regulating the functionalities of nanostructured materials. Here we report a hybridization approach to improve oxygen electrocatalyst performance of metal oxi...

Monolithic three-dimensionally integrated memristor-thin-film transistor for electrically programmable multimode reservoir computing

Reservoir computing offers an efficient framework for processing temporal information, but most hardware reservoirs exhibit fixed or narrowly tunable dynamics determined by intrinsic material relaxation time. A monolithically integrated memristor-thin-film transistor reservoir ke...

Empirical performance of rough volatility models in the KOSPI 200 options market using deep surrogates

Purpose This study provides a systematic comparison of the pricing performance of the rough volatility models—rBergomi and rHeston—with that of classical one-factor stochastic volatility (SV) and stochastic volatility jump-diffusion (SVJ) models in the KOSPI 200 index options mar...

Criteria-based probable REM sleep behaviour disorder and risk of Lewy body dementia: analyses of a memory clinic cohort and a community cohort

Abstract Background REM sleep behaviour disorder (RBD) is the strongest prodromal marker of alpha-synucleinopathies, but whether a brief questionnaire carries prognostic information for Lewy body dementia is unclear. We tested whether criteria-based probable RBD (pRBD)—a question...
