Optimization of Biaxial Tensile Specimens Incorporating Polymer Machinability

고분자 재료의 다축 기계적 거동 평가에는 이축 인장 시험이 필수적이다. 하지만 ISO 16842 표준 시편은 좁은 슬릿 구조로 인해 제작 공정에 제약이 있어 고분자 소재에 적용하기 어렵다. 본 연구에서는 이를 원형 홀 등간격 배열로 대체한 천공 십자형 시편을 제안하였다. 완전요인배치법으로 생성한...

Empirical Predictions of The NavMesh Cosmology: Resolving the Hubble Tension and Quantizing Time Dilation via Spatial Latency

We present four falsifiable empirical predictions of The NavMesh Cosmology, a parameter-free discrete spacetime framework. The model derives cosmic acceleration and spatial kinematics strictly from an inverse relation between the expansion rate and baryonic information density (H...

Population-adapted nolla method for dental age estimation in Northwestern Romanian children

Accurate dental age (DA) estimation is essential in pediatric dentistry, orthodontic treatment planning, and forensic practice; however, the applicability of international reference standards varies across populations. This study aimed to evaluate the accuracy of a population-ada...

The missing improvers: Tau pathology, neuroplasticity, and the case for tau-informed patient selection before amyloid immunotherapy

Amyloid immunotherapy with lecanemab and donanemab has been approved on the basis of statistically significant slowing of cognitive and functional decline in early Alzheimer's disease (1,2). Yet clinicians treating individual patients face the everyday challenge of estimating whe...

The reliability of the Meloq EasyBase force platform for assessing jump performance and balance parameters in adolescent male basketball players

Reliable assessment of balance and jump performance is essential for monitoring neuromuscular function, athletic performance, and injury risk in adolescent basketball players. Portable force platforms may provide practical advantages for routine clinical and field-based evaluatio...

NGO mediation, gender and youth inclusion, and socio-economic feasibility of post-conflict water systems in Ethiopia’s Amhara Region

In post-conflict rural Ethiopia, rebuilding water infrastructure requires restoring inclusive governance, yet the role of NGOs in mediating women’s and youth participation remains underexplored. This mixed-methods study investigated how NGO mediation shapes the socio-economic fea...

Diagnostic value of CT-quantified abdominal fat parameters for metabolic dysfunction-associated fatty liver disease

To analyze the diagnostic value of CT-derived abdominal fat indices in predicting MAFLD and establish an integrated diagnostic system. A retrospective study on 174 patients with a previous history of abdominal CT examination in our institute between January 2022 and June 2024 was...

Analytic BoundaryTerms for Arbitrary Crystal Geometriesand Direct-Sum Evaluation of Madelung Constants in Triclinic Lattices

Abstract The direct-sum evaluation of Madelung constants is complicated by the conditional convergence of lattice sums, which gives rise to a shape-dependent boundary term. In this work, we present, for the first time, a closed-form analytic expression for this boundary term that...

Verification of Cooling Performance of Internal Fan in High-Speed Induction Motor

The cooling performance of high-speed induction motors plays a crucial role in their stability and durability. Enhancing the cooling efficiency of the motor, including internal cooling ducts and fans, is essential for design and operation. In this study, experiments were conducte...

Seed-based functional connectivity of the anterior cingulate cortex and the posterior insula predicts placebo analgesia in Parkinson’s disease

Chronic pain affects up to 80% of people with Parkinson’s disease (PD) and remains difficult to treat. Functional brain connectivity can predict analgesic response in other conditions, but has not been explored in PD. To assess whether baseline resting-state functional connectivi...

Quantifying the fiscal benefits of obesity prevalence reduction in China

With obesity becoming increasingly prevalent in China, its impact extends beyond health losses to wider public finance pressures. This study assessed the fiscal implications of reducing obesity prevalence from the government perspective and explored the potential fiscal benefits...

Stakeholder perceptions of an early essential newborn care simulation-based training in western China: a qualitative study

Neonatal mortality remains a global concern, especially in China, where regional disparities persist. Early essential newborn care (EENC) consists of a set of evidence-based and cost-effective interventions, including but not limited to, skin-to-skin contact, neonatal resuscitati...

Discovery of a novel MurA inhibitor via AlphaFold 3 model-based virtual screening

S. aureus is one of the most important bacteria associated with human diseases. UDP-N-acetylglucosamine 1-carboxyethylene transferase (MurA) is an important enzyme involved in the synthesis of peptidoglycan in bacterial cell walls. The crystal structure of MurA from S. aureus has...

Voice metrics and workload in helicopter rescue: insights from ninety-six cockpit recordings

The relationship between subjective workload and task performance is multifaceted. In aviation research, task performance is typically evaluated using multiple variables. Voice metrics can provide valuable insights regarding operational improvements and offer objective assessment...

A Giant Ovarian Fibrothecoma Arising From Residual Ovarian Tissue Mimicking Advanced-Stage Ovarian Malignancy: A Short Report of Demons–Meigs Syndrome

The Annali Italiani di Chirurgia (ISSN/eISSN: 0003-469X/2239-253X) is the oldest surgical journal in Italy. It covers all aspects of surgery and its allied disciplines, including elective, emergency and experimental surgery, as well as problems involving technology, teaching, org...

Membrane behavior and diffusion in bentonite for different anions

Bentonite clay is widely used in engineered barriers, such as geosynthetic clay liners (GCLs), to safely contain wastes and chemicals. In addition to low hydraulic conductivity and diffusion coefficients, bentonite has been shown to exhibit membrane behavior (anion restriction) w...

Comparative effects of semaglutide tirzepatide and retatrutide on renal fibrosis in UUO and aged mice

Chronic kidney disease is a major health burden. Given the therapeutic potential of GLP-1 receptor agonists (semaglutide, tirzepatide, and retatrutide) in diabetic nephropathy, we evaluated their anti-fibrotic and anti-inflammatory effects in non-diabetic renal fibrosis using HK-...

Design of heat treatment and magnetic field-assisted machining for microstructure and surface corrosion control in Inconel 718

It has been demonstrated that Magnetic Field-Assisted Machining (MAM) has strong potential for improving surface quality and tailoring microstructure in hard-to-machine heat-treatable Inconel 718 (IN718). However, the influence of MAM on corrosion performance of IN718, particular...

Beyond HAS-BLED in very elderly patients with atrial fibrillation treated with direct oral anticoagulants: predictors of major bleeding in a real-world cohort

Bleeding risk assessment in very elderly patients with atrial fibrillation (AF) receiving direct oral anticoagulants (DOACs) remains challenging. The HAS-BLED score is widely used but may have limited applicability in this population. We aimed to evaluate its performance and to i...

Mitigating firm-capacity delay risk through stochastic planning of flexible generation and battery storage

Energy-transition plans often assume that committed firm-capacity projects are commissioned on schedule, yet delayed delivery can create temporary adequacy risks and require additional mitigation resources. This study develops a scenario-based stochastic adequacy-mitigation model...
