Disturbance-Aware Preview Control for Humanoid Robot Towing of Heavy Wheeled Loads with Traction Force Compensation

Most existing humanoid robots possess a payload capacity below 10 kg, which is insufficient for practical material transport tasks. A natural engineering solution is to enable humanoid robots to tow wheeled trailers or hand carts, transferring the vertical load to the wheeled car...

Targeting PRMT5 alleviates diabetic cardiomyopathy: mechanisms involve Ndufs2 R118 dimethylation-mediated complex I protection and serum PRMT5 as a biomarker

Abstract Background Diabetic cardiomyopathy (DCM) is defined by progressive cardiac dysfunction driven by myocardial ATP depletion, where mitochondrial electron transport chain (ETC) Complex I dysfunction acts as a critical factor. Protein arginine methyltransferase 5 (PRMT5) mai...

Fossil denticles reveal how ocean productivity shapes shark baselines and recovery potential

Shark populations on coral reefs have declined globally, but few baselines exist to quantify natural variability before human impact. Using fossil dermal denticles preserved in reef sediments, we reconstructed shark communities across the Isthmus of Panama before substantial expl...

Incidence and Risk Factors for Progression of Pachychoroid Subtype

Importance The incidence and determinants of progression across the pachychoroid subtype remain incompletely characterized, limiting risk stratification and follow-up strategies. Objective To evaluate progression, diagnostic transitions, and associated risk factors in eyes with p...

Do information and communication technologies empower female workers? Evidence from Vietnam

We examine the impact of information and communication technology (ICT) adoption on female employment outcomes in Vietnam, using data at both the firm and household levels. Our identification strategy leverages geographic variation in the engineering costs of connecting to Vietna...

Beyond autonomy: cultural habitus and social scaffolding in elderly vaccination in post-pandemic Hong Kong

The COVID-19 pandemic reshaped vaccination behaviors, yet post-pandemic attitudes toward routine immunization among older adults remain underexplored in aging societies like Hong Kong. This study explores the impact and implications of the pandemic on influenza and pneumococcal v...

Reproducible left anterior-superior hypothalamic enlargement in episodic migraine: evidence from two independent cohorts

Growing evidence implicates the hypothalamus as a key structure in migraine pathophysiology; however, our understanding of its precise role and of the specific nuclei involved remains limited. We combined MRI data from our laboratory with publicly available MRI datasets from Open...

Comparative Efficacy Of Different Computer-Aided Detection Products in Colonoscopy: A Network Meta-Analysis Of Randomized Controlled Trials.

Background and aims: Multiple computer-aided detection (CADe) systems have been developed to improve adenoma detection during colonoscopy, but their comparative efficacy and consistency of effect remain uncertain. This network meta-analysis aimed to compare the efficacy of differ...

A Clinically Accessible Nomogram for Identifying Likely Psoriatic Arthritis Among Patients with Psoriasis: A Multicenter Cross-Sectional Study

Background/Objectives: Psoriatic arthritis (PsA) affects up to 30% of psoriasis patients but remains underdiagnosed due to heterogeneous early manifestations. Existing tools rely on advanced imaging or biomarkers, limiting feasibility. This study aimed to develop a simple nomogra...

Unravelling undergraduates’ development of evaluative judgments through AI-supported internal feedback

Making evaluative judgments is a core lifelong learning capacity and the foundation of student feedback literacy. However, its development in second language (L2) writing remains underexplored. This qualitative case study investigated how 28 undergraduates developed evaluative ju...

Cost utility analysis of two BK polyomavirus screening strategies: quantitative polymerase chain reaction vs 2-stage approach

Screening for BK polyomavirus (BKPyV) with quantitative polymerase chain reaction (qPCR) or a 2-stage approach with urine cytology followed by qPCR are acceptable strategies. However, the magnitude of the health benefits and incremental cost of adopting these 2 screening strategi...

Exploring the hydrogen abstraction pathway in HOM formation from α -pinene photooxidation systems under varying NO conditions

Abstract. Highly oxygenated organic molecules (HOM) are formed via autoxidation during ⚫OH-initiated oxidation of α-pinene. We investigated the relative contributions of OH-addition and hydrogen (H)-abstraction to HOM formation from α-pinene photooxidation under varying nitrogen...

Experimental causal inference from measurements alone in the presence of spatial and temporal quantum correlations

The causal structure of a set of events specifies which events influence which others. Determining this structure, known as causal inference, is a fundamental task in science. Reset-style intervention is commonly used to determine causal structure in classical scenarios. However,...

Living Structure + AI: A New Episteme for Liberal Arts and Whole-Person Education in the Era of Artificial Intelligence

The rapid integration of artificial intelligence (AI) into higher education marks a radical epistemic shift, unsettling long-held assumptions about how knowledge is made, taught, and judged. This paper argues that the theory of living structure offers a timely foundation for libe...

Healing Following Endoscopic Reconstruction of the Anterior Skull Base in Patients With Sinonasal Malignancies

ABSTRACT Background Healing dynamics after anterior skull base (ASB) reconstruction following transnasal endoscopic surgery (TES) for sinonasal malignancies remain poorly characterized. This study aimed to describe the postoperative healing process, quantify time to healing, iden...

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Doping is a cornerstone strategy for enhancing charge transport in semiconducting polymers, important for their application in, for example, semi-transparent electrode materials, thermoelectric devices, and antistatic coatings. Both chemical and electrochemical doping have, for t...

Reconstructing Solvation Structure via Strongly Nucleophilic Anions for High‐Rate and Low‐Temperature Graphite||LFP Pouch Cells in PC‐Based Electrolyte

ABSTRACT Regulating Li + solvation structure in Propylene carbonate (PC)‐based electrolytes modulates solid‐electrolyte interphase (SEI) formation and desolvation, enabling compatibility with graphite anodes. However, existing high‐ and localized high‐concentration strategies rem...

Allosterically Controlled Capture of Mutually Repulsive Guests With Positive Cooperativity and Ultrahigh Affinity

ABSTRACT A hexacationic cage incorporating three urea units can encapsulate two mutually repulsive anions in close proximity through a combination of hydrogen bonding and electrostatic interactions. This leads to exceptionally high binding affinities, with a K 1 × K 2 value of ap...

Age-Associated Patterns of Cardiovascular Risk and Disease Phenotypes Across Diverse Care Settings: The GLOB-cAGE Consortium

Reported prevalence of cardiovascular disease (CVD) risk factors and phenotypes varies widely. In multi-cohort analyses, such variation reflects population risk, care setting, and data capture. We harmonized baseline data from four analytic cohorts (N=54,188, aged ≥50 years) in f...

Genetic Predisposition and Pharmacological Effects Shape the Divergent Effects of Type 2 Diabetes on Atherosclerosis

Abstract Type 2 diabetes mellitus (T2D) increases the risk of atherosclerotic diseases, including coronary artery disease (CAD), but decreases that for abdominal aortic aneurysm (AAA), forming an intriguing diabetes-atherosclerosis paradox. We investigate how genetic underpinning...
