Metallic Slit-Plate Dampers: Damage Evaluation with Metal Magnetic Memory Technique and Application to Structures with Rocking Columns

Metals, 2019
Inelastic deformation of metallic materials is one of the most effective mechanisms for the dissipation of energy input to a structure by an earthquake. Metallic dampers are special devices that resort to this source of energy dissipation, proving to be ...

A Long‐Lived Human Neurovascular PENTA Culture Model Captures Incomplete Vascular Repair and Glia‐Associated Signaling After Traumatic Brain Injury

Advanced Healthcare Materials, EarlyView.
A long‐lived, five‐cell‐type human neurovascular (PENTA) model recreates vascular disorganization and incomplete repair after traumatic brain injury (TBI). By integrating endothelial, glial, neuronal, and immune components within a 3D scaffold, the platform enables time‐resolved analysis of neurovascular remodeling and provides a human‐relevant system ...

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

Advanced Healthcare Materials, EarlyView.
This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

A simplified model for rocking panels with friction connections [PDF]

In recent decades, various rocking systems have been proposed to enhance the self-centring capacity of structures after seismic events. Sometimes dissipative devices have been added to control peak lateral displacements. However, the computational models

Gellan Gum Fluid Gel System for Controlled‐Delivery of Cytokine‐Licensed MSC‐EVs to Enhance Corneal Repair in Limbal Stem Cell Deficiency

Advanced Healthcare Materials, EarlyView.
Gellan gum fluid gel (FG) enables controlled ocular delivery of mesenchymal stromal cell (MSC)‐derived extracellular vesicles (EV). Its shear‐thinning, solid‐liquid‐solid rheology ensures prolonged ocular retention. Sustained MSC‐EV release (∼18% in 6 hrs) supports effective EV ocular delivery.

Towards a unified description of rocking structures

, 2013
Numerous studies on the rigid rocking block have generated a wealth of knowledge about rocking behavior. However, evaluation of more complex rocking systems requires the derivation and solution of complicated equations of motion.

Seismic overturning of damped rocking structures

, 2011
Numerous structures exhibit rocking behavior during earthquakes and there is a continuing need to retrofit these structures to prevent collapse. The behavior of stand-alone rocking structures has been thoroughly investigated, but there are relatively few
