Walking control of humanoid robots based on improved footstep planner and whole-body coordination controller.

High-speed walking is fundamental for humanoid robots to quickly reach the work site in emergency scenarios. According to biological studies, the coordinated motion of the arms and waist can significantly enhance walking speed and stability in humans. However, existing humanoid robot walking control frameworks predominantly focus on leg control, often overlooking the utilization of upper body joints.

Highly Linear Stretching Sensors with Braiding Structure Constraining Cracks.

Stretchable fiber-based electronics can be triggered by joint activities of human beings to produce varied resistance signals, provoking extensive attention from sports fitness, health care, wearables, and other related fields. The linearity of the response signal, as a quintessential parameter, is paramount for the performance evaluation of stretching sensors. In this study, three-strand braid (TSB) is fabricated via braiding three filaments of polypyrrole/polyurethane (PPy/PU).

Cardiolipin oxidized by ROS from complex II acts as a target of gasdermin D to drive mitochondrial pore and heart dysfunction in endotoxemia.

Cardiac dysfunction, an early complication of endotoxemia, is the major cause of death in intensive care units. No specific therapy is available at present for this cardiac dysfunction. Here, we show that the N-terminal gasdermin D (GSDMD-N) initiates mitochondrial apoptotic pore and cardiac dysfunction by directly interacting with cardiolipin oxidized by complex II-generated reactive oxygen species (ROS) during endotoxemia.

Single NV centers array preparation and static magnetic field detection.

To solve the problem of static magnetic field detection accuracy and consistency, we prepared an array of single NV centers for static magnetic field vector and gradient detection using the femtosecond laser direct writing method. The prepared single NV centers are characterized by fewer impurity defects and good stress uniformity, with an average spatial positioning error of only 0.2 µm.

Ambient NO exposure induced cardiotoxicity associated with gut microbiome dysregulation and glycerophospholipid metabolism disruption.

An average daily increase of 10 μg/m in NO concentrations could lead to an increased mortality in cardiovascular, cerebrovascular of 1.89%, 2.07%, but the mechanism by which NO contributes to cardiotoxicity is rarely reported.
