Re‐Purposing a Modular Origami Manipulator Into an Adaptive Physical Computer for Machine Learning and Robotic Perception

Advanced Science, EarlyView.
Reservoir computing in the physical domain promises an alternative, more energy‐efficient approach to machine learning. However, the correlation between mechanical design and computing power remains elusive. This study sheds light on this gap by repurposing a meta‐stable modular origami manipulator into an adaptive computing kernel that can perform ...

Bio‐Inspired SA‐FA Bionic Dual Receptor Electronic Skin for Intelligent Gesture and Material Cognition Systems Enhanced by Static‐Dynamic Mutual Interaction

Advanced Science, EarlyView.
In this work, bionic dual receptor (BDR) e‐skin based on the iontronic and triboelectric effects is proposed, inspired by the slow‐adapting and fast‐adapting receptors. Motivated by intelligent software algorithms and high‐speed hardware circuits, the proposed intelligent autonomous material cognition system integrated with the EDB e‐skin can ...

Stimulation of an entorhinal-hippocampal extinction circuit facilitates fear extinction in a post-traumatic stress disorder model

The Journal of Clinical Investigation
Effective psychotherapy of post-traumatic stress disorder (PTSD) remains challenging owing to the fragile nature of fear extinction, for which the ventral hippocampal CA1 (vCA1) region is considered as a central hub. However, neither the core pathway nor

Experimental and Analytical investigations of the actions taking place in a synchronous machine during the starting period when the starting is effected by means of alternating current

, 1918
The literature on the subject of the present investigation is somewhat meagre. A rotary converter or synchronous motor no! provided with any special starting devices forms, when started from the alternating current side, a type of induction motor whoso Htator is provided with a polyphase winding, and whoso rotor has a single-phase (or single magnetic ...

Kinetically Controlling Surface Atom Arrangements in Thermally Robust, Amorphous High‐Entropy Alloy Nanoparticles by Solvent Selection

Advanced Science, EarlyView.
This work leverages the level of carbon supersaturation in the metallic constituents during particle formation to regulate nanoparticle morphology, structure, and composition distribution. The solvent‐dependent (C/(C+O)) ratio and the relative kinetics of the competing reactions of carbon shell formation, coalescence of metallic constituents, and ...

Temporal Stretch‐Induced Nuclear Mechanosensing Coordinates Early Chromatin Accessibility and Genome Protection

Advanced Science, EarlyView.
Cyclic stretching of fibroblasts triggers coordinated nuclear mechanosensing events, including calcium ion release, perinuclear actin assembly, emerin translocation, and H3K9me3 loss, increasing chromatin accessibility for specific genes related to mechanotransduction and repair.
