Autonomous Agentic AI for Adaptive Cure Optimization and Defect Prevention in Thermoset Polymer Composite Manufacturing
Abstract: Thermoset polymer composites occupy a central position in modern structural manufacturing, from aircraft fuselages to wind-turbine blades. Despite progress in resin chemistry and fiber architecture, the “cure process” that transforms compliant preforms into load-bearing structures remains difficult to manage. Manufacturers encounter ‘voids’, “interlaminar delaminations”, and “spring-back distortion” when curing complex or thick-section parts. The cause is not ignorance of the relevant physics, but rather that ‘temperature’, ‘chemistry’, ‘rheology’, and ‘mechanics’ …

Perioperative stress relief: a new role for the love hormone???
Abstract: AbstractThe hormone oxytocin(OXT) was originally known to stimulate labour and maternal milk ejection. It is also known to produce anti-stress like effects, anxiolytic effects, improvement in social interaction, reduction in blood pressure and cortisol levels and promotion of growth and healing. It is in fact popularly called as the ‘love hormone’, or the ‘hug hormone’ or the ‘cuddle hormone’. It is administered commonly intravenously in labor rooms and maternity suites …

Thermodynamic Irreversibility in Semen Transport
Abstract: Sperm ejaculation is a vital reproductive process that involves both complex biological functions and energetic mechanisms. Beyond the physiological aspects, thermodynamics offers a framework to analyze energy conversion, exergy use, and irreversibility during sperm activity. ATP provides the main source of exergy for motility, but part of this energy is inevitably lost as heat and entropy generation, reflecting inefficiencies in the process. Because heat regulation directly affects metabolic rates, motility …
