Matrix Stiffness Governs Fibroblasts’ Regulation of Gingival Immune Homeostasis
Advanced 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 ...

Will the tachyonic Universe survive the Big Brake? [PDF]
, 2010 We investigate a Friedmann universe filled with a tachyon scalar field, which behaves as dustlike matter in the past, while it is able to accelerate the expansion rate of the universe at late times.

Development of Heat Engines Powered by Twisted and Coiled Polymer Fiber Actuators
Advanced Materials Technologies, EarlyView.Continuously rotating engines driven by thermally responsive actuating materials can turn waste heat into useful energy. For the first time heat engines operated by twisted and coiled polymer fiber actuators are demonstrated with engine design guided by two simple analytical models.

Evaluation of a sudden brake warning system: Effect on the response time of the following driver [PDF]
, 2010 This study used a video-based braking simulation dual task to carry out a preliminary evaluation of the effect of a sudden brake warning system (SBWS) in a leading passenger vehicle on the response time of the following driver.

Advanced Robotics Research, EarlyView.This study introduces a hybrid robot that integrates mechanical assistance by musculoskeletons (i.e., soft pneumatic muscle with rigid exoskeletal extensions), neuromuscular electrical stimulation, and vibrotactile feedback in a lightweight wearable mechatronic complex applicable to the paretic ankle–foot poststroke for gait restoration. The system can
