Toward Mechanical Intelligence in Robotics

Advanced Robotics Research, EarlyView.
Robots can use their physical bodies to perform functions usually assigned to electronic sensors and controllers. This perspective defines mechanical intelligence through three core operations: filtering inputs, routing mechanical signals, and switching between states.

Pengaruh Tes Elevasi Tungkai Secara Pasif terhadap Variasi Pletismograf untuk Penilaian Responsivitas Cairan pada Pasien yang Dilakukan Pembedahan dengan Anestesi Umum

Jurnal Anestesi Perioperatif, 2016
Fluid responsiveness assessments have shown to be an important matter in perioperative fluid optimization. Respiratory variations in pulse oximetry plethysmographic waveform amplitude (∆POP) and passive leg raising have been shown as promising indicators

A Critical Time Window of Neocortex Modulation for Remote Fear Memory in Rats and Humans

Advanced Science, EarlyView.
This study identifies a delayed consolidation window around 18 h after fear learning in the mPFC essential for remote fear memory. VTA dopaminergic input during this window sustains remote memory in rats, while non‐invasive stimulation of homologous human mPFC at the corresponding time selectively weakens remote but not recent fear memory, revealing a ...

Not Bad: Passive Leg Raising in Cardiopulmonary Resuscitation-A New Modeling Study [PDF]

Frontiers in Physiology, 2017
Aim: To evaluate, using a simulated haemodynamic circulation model, whether passive leg raising (PLR) is able to improve the effect during cardiopulmonary resuscitation (CPR); to expose the possible reasons why PLR works or not. Materials and Methods: We adapted a circulatory model for CPR with PLR.

Harnessing Phase Separation for the Development of High‐Performance Hydrogels

Advanced Science, EarlyView.
ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...
