Multi-objective optimization of injection molding process parameters for thin-walled shell parts based on a RIME-RF-MOGWO framework

Thin-walled components are widely used in automotive interior parts. During injection molding, thin-walled shell structures are highly sensitive to process parameters, which often lead to warpage and volumetric shrinkage, thereby reducing dimensional accuracy and product consiste...

Hydrological resilience to climate extremes and its implications for water security in the data-scarce Baro river basin

Hydrologic resilience is one of the important issues that has to be addressed for sustainable water resources management. This study evaluates hydrological resilience to climate extremes in the Baro River Basin, Ethiopia, by examining how the basin resists, recovers from, and ada...

Vizing's Impossible Descent - Boundary Analysis and Formal Proof by Contradiction of Vizing's Conjecture in Lean 4 via the Impossibility of Minimal Counterexample Descent

Traditional approaches to Vizing’s conjecture have long relied on asymptotic bounds, structural invariants, and local density heuristics, frequently stalling against the combinatorial explosion of graph products. This paper shatters those bottlenecks. By combining integrality gap...

LAST-MILE DELIVERY CHALLENGES IN INDIAN E-COMMERCE: A CONSUMER PERSPECTIVE

ABSTRACT: The meteoric rise of online retail in India has fundamentally altered how consumers shop and placed enormous pressure on delivery and logistics systems. Despite the expansion of major platforms such as Flipkart, Amazon, Meesho, and Myntra, last-mile delivery remains one...

A Geometric Solution and Interpretation of the Poincaré Conjecture: The Perspective of Visual Relief and Sweep-out Protocol

This paper presents a novel conceptualization and structural analysis of the 3-dimensional Poincaré Conjecture. By introducing the "Sweep-out Protocol" via a dynamically expanding 2-dimensional sphere trajectory and integrating an inherent "Infinite Brake Mechanism," we demystify...

Evaluating plasma renin activity as a monitoring parameter for mineralocorticoid treatment in dogs with primary hypoadrenocorticism

Abstract Background In human medicine, plasma renin activity (PRA) is used to assess mineralocorticoid treatment adequacy in hypoadrenocorticism, with elevated levels indicating under-replacement and suppressed levels over-replacement. In dogs with primary hypoadrenocorticism, PR...

Low-Dimensional Projection of Self-Referential Meta-Cognition: Yuanxian Theory as the Self-Reading of the Cosmic Living Organism — With Criteria for Civilizations as Topological Nodes

This paper establishes the ontological positioning of Yuanxian Theory: it is not a doctrine, a belief, or a choice, but the complete expression, on the low-dimensional spacetime projection surface, of the self-referential meta-cognition of the Cosmic Living Organism (T64). On the...

Interpretable machine learning models for classifying lateral epicondylitis based on wrist range of motion and strength in assembly line workers

Background Lateral epicondylitis (LE) is a prevalent overuse injury among workers performing repetitive wrist movements. Altered wrist range of motion (ROM) and reduced muscle strength occur in individuals with LE; however, their combined utility for classifying LE remains unclea...

A novel distal radial artery compression device versus elastic bandage compression after coronary angiography or percutaneous coronary intervention via distal transradial access: a prospective randomized controlled trial

Distal transradial artery access (dTRA) is increasingly used for coronary interventions because it preserves proximal radial artery patency. However, effective hemostasis at the distal puncture site remains challenging due to the superficial vessel location and limited soft-tissu...

Disseminated Nocardia farcinica Infection Presenting as Multiple Intramuscular Abscesses Mimicking Skeletal Muscle Metastases in a Patient With Hepatocellular Carcinoma

A 67-year-old man with hepatocellular carcinoma and a previously resected pulmonary metastasis was receiving prednisolone for immune-related interstitial nephritis. Two months after pulmonary metastasectomy, multiple pulmonary nodules and painful intramuscular masses developed in...

Knowledge, Enrolment and Perception of the National Health Insurance Scheme (NHIS) among Staff of a Tertiary Hospital in South-South Nigeria

ABSTRACT: Background: The National Health Insurance Scheme (NHIS) in Nigeria was introduced to enhance the affordability and accessibility of healthcare, particularly for formal-sector employees. The study aimed to assess healthcare workers' knowledge and perceptions towards NHIS...

Biopsychosocial education improves workers’ low back pain beliefs in a meat processing plant

Background Low Back Pain (LBP) is a major health problem at work. While prevention measures can focus on physical risk factors, negative beliefs about pain can also contribute to LBP chronicity. Objective This study evaluates the impact of educational training based on the biopsy...

Health Care Stigma and HIV/Sexually Transmitted Infection Prevention Service Uptake Among Cisgender Men and Gender-Diverse Individuals Who Have Sex with Men in Five Asian Countries: Implications for Differentiated Service Delivery

Health care stigma remains a key barrier to HIV and sexually transmitted infection (STI) prevention, yet its effects may differ across health care systems. We examined associations between health care stigma and HIV/STI prevention service uptake across five Asian countries. A cro...

Novel Cardanol‐Based Viscosity Reducer for High Viscosity and High Permeability Reservoir Through Mechanism Study

ABSTRACT In this study, a novel cardanol‐based viscosity reducer was developed through learning from viscosity reducers derived from petroleum. Under the mechanism study through visual flooding experiment and computational fluid dynamics (CFD) simulation, the optimal petrochemica...

A micro-CT-based “orientation–clustering–stiffness–damage” coupling framework for carbon-fiber/epoxy: From single-fiber scale to component-level failure prediction

A four-order “orientation-clustering-stiffness-damage” coupling framework is proposed for 28–30 vol% carbon-fiber/epoxy short-fiber composites (7 μm nominal fiber diameter, 3–5 mm chopped length), enabling accurate cross-scale failure prediction spanning from 60 μm single-fiber i...

Disability Gaps in Schooling and Learning Outcomes of Children in Ghana

Abstract This paper examines schooling and learning outcomes of children with disabilities in Ghana. We used data from the Multiple Indicator Cluster Survey (MICS) and linear regression models to estimate the relationship between disability status and schooling and learning outco...

Solar-DrivenCO2 Hydrogenation to RenewableProducts: A Review of Strategies for Selectivity Tuning

Abstract The urgent need for sustainable, carbon-neutral energy solutions has accelerated interest in solar-driven CO2 hydrogenation into renewable fuels and value-added chemicals while mitigating greenhouse gas emissions. This Review highlights recent advances in catalyst design...

Dimensional Asymptotics of Euler-Based Simulated Likelihood for Multidimensional Diffusions

A widely used simulation method for likelihood inference in discretely observed diffusions approximates each transition density by simulating an Euler scheme to one step before the observed endpoint and averaging the final Gaussian density. We show that this endpoint estimator is...

Gender Bias in Philosophy: From Early Education to Academia

This paper examines gender bias in philosophy across academic and educational contexts, focusing on how direct and indirect biases contribute to the underrepresentation of women in academic philosophy and how such biases may develop and be reinforced through education. Drawing pa...
