The Biomechanical Impact of Slipper Sole Compliance on Lumbar Spine Load: A Quantitative Analysis of Indoor Footwear Ergonomics
Abstract: Abstract The global shift toward remote work has significantly increased the duration of indoor footwear usage, yet the ergonomic standards for slippers remain critically under-researched compared to athletic or industrial footwear. While "high-compliance" or soft slippers are traditionally marketed for immediate comfort, excessive mechanical softness may lead to foot instability, altered gait kinetics, and subsequent compensatory stress on the lumbar spine. This study aims to quantify the correlation between varying …

Deep Reinforcement Learning-Based MPPT for PV Systems Under Partial Shading: A Hybrid Metaheuristic-Optimized Control Framework.
Abstract: Partial shade and quickly changing environmental conditions make Maximum Power Point Tracking (MPPT) in photovoltaic (PV) arrays particularly difficult. In these situations, traditional algorithms frequently fail to find the global optimum or experience sluggish convergence and steady-state oscillations. To obtain reliable, real-time MPPT under non-uniform irradiance, this research suggests a hybrid control architecture that combines a deep recurrent reinforcement learning (DRL) agent with metaheuristic-based parameter optimization and a digital-twin training …

Autoimmune Polyglandular Syndrome Type 1 (APS-1): A Rare Yet Crucial Condition to Recognize
Abstract: Autoimmune Polyglandular Syndrome Type 1 (APS-1), also known as Autoimmune Polyendocrinopathy-Candidiasis-Ectodermal Dystrophy (APECED), is a rare autosomal recessive disorder caused by mutations in the AIRE (Autoimmune Regulator) gene. This syndrome is characterized by a triad of chronic mucocutaneous candidiasis, hypoparathyroidism, and adrenal insufficiency, although it can affect multiple other organ systems. APS-1 arises from a failure of central immune tolerance, resulting in autoimmunity against various endocrine and non-endocrine tissues. The …
