The value of fitting adult upper limb amputees with electrically powered prostheses is assessed. In a series of 164 amputees, complete or useful acceptance of an electrically powered prosthesis was recorded in 80% of below-elbow amputees, 69% of above-elbow amputees and 72% of high level amputees. Patients expressed satisfaction with the combination of comfort, cosmesis and function. Results indicate that, accepting the high cost, an electrically powered prosthesis can provide important function to the upper limb amputee.

Coal power plants adversely impact air pollution, but they also pose a risk to our water sources. Discharge wastewater from power plants may degrade the quality of nearby water bodies. This study evaluates the potential water-related environmental impacts of electricity generation at an ultra-supercritical coal power plant in Malaysia using the life cycle assessment method.

We propose a novel contactless droplet manipulation strategy that combines electrostatic tweezers (ESTs) with lubricated slippery surfaces. Electrostatic induction causes the droplet to experience an electrostatic force, allowing it to move with the horizontal shift of the EST. Because both the EST and the slippery operating platform prepared by a femtosecond laser exhibit a strong binding effect on droplets, the EST droplet manipulation features significant flexibility, high precision, and can work under various operating conditions.

Recent developments in artificial intelligence and the internet-of-things have created great demand for low-power microelectronic devices. Two-dimensional (2D) electrical switching materials are extensively used in neuromorphic computing technology, yet their high leakage current and low endurance impede their further application. This study presents a vertical crossbar-structured conductive-bridge threshold switching device based on 2D TaSe oxide.

Background: Transcatheter renal denervation (RDN) remains inconsistent despite developments in ablation technologies, due to the lack of an intraprocedural physiological end point.
Objective: To identify whether aorticorenal ganglion (ARG) guided RDN using microwave (MW) catheter leads to more consistent denervation outcomes compared with empirical MW ablation.
Methods: Pigs underwent sham procedure (n=8) or bilateral RDN using an in-house built open-irrigated MW catheter.

A reward shaping deep deterministic policy gradient (RS-DDPG) and simultaneous localization and mapping (SLAM) path tracking algorithm is proposed to address the issues of low accuracy and poor robustness of target path tracking for robotic control during maneuver. RS-DDPG algorithm is based on deep reinforcement learning (DRL) and designs a reward function to optimize the parameters of DDPG to achieve the required tracking accuracy and stability. A visual SLAM algorithm based on semantic segmentation and geometric information is proposed to address the issues of poor robustness and susceptibility to interference from dynamic objects in dynamic scenes for SLAM based on visual sensors.
