Prescribed energy connecting orbits for gradient systems

open access: yes, 2019
We are concerned with conservative systems $\ddot{q}=\nabla V(q), \; q\in\mathbb{R}^N$ for a general class of potentials $V\in C^1(\mathbb{R}^N)$.

Membrane Vesicles from Lacticaseibacillus Casei BL23 Exhibit Antimicrobial Activity Against Escherichia coli and Immunostimulatory Effects on Human Peripheral Blood Mononuclear Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Membrane vesicles derived from the probiotic Lacticaseibacillus casei BL23 demonstrate antimicrobial properties against Escherichia coli and a potential biological effect in improving the overall survival of C. elegans infected with Pseudomonas aeruginosa. These vesicles stimulated immune responses in primary cells without causing toxicity. Our results

Design oriented simulation of contact-friction instabilities in application to realistic brake assemblies [PDF]

open access: yes, 2010
This paper presents advances in non-linear simulations for systems with contact-friction, with an application to brake squeal. A method is proposed to orient component structural modifications from brake assembly simulations in the frequency and time ...

Heat generation problem in the eddy current brake: a mini-review

open access: yesCogent Engineering
One of the functions of a brake system is to reduce or maintain the speed of a vehicle. The braking process generally converts kinetic energy into heat.

Adaptive Twisting Metamaterials

open access: yesAdvanced Materials, EarlyView.
This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Brake Failure Detection and Emergency Braking System

open access: yesInternational Journal of Innovative Technology and Exploring Engineering, 2019
Now a days accidents might occur because of varied reasons, the foremost reason is equipment failure and is happened due to improper maintenance of the products. To prevent these abnormal situations and to protect one’s life from these accidents, there's a neccessity for watching of braking system in cars.vehicle safety is a special term means ...

Matrix Stiffness Governs Fibroblasts’ Regulation of Gingival Immune Homeostasis

open access: yesAdvanced Materials, EarlyView.
This study identifies a “mechano‐epigenetic” checkpoint in which matrix stiffness governs the immune responses of gingival fibroblasts. Using biomimetic hydrogels and human gingival explants, the studies revealed that restoring extracellular matrix stiffness actively suppresses inflammation via non‐canonical NF‐κB signaling and DNA methylation ...
