Rectification current in overdamped ratchets can be easily controlled by applying two driving signals and tuning either their relative phase or their frequency ratio. The interplay of the two inputs generates intriguing transport mechanisms that can be implemented to optimize shuttling and separation of particles in a variety of physical and technological applications.

Active force-feedback holds the potential for precise and rapid controls. A high performance device can be built from a surplus disk drive and controlled from an inexpensive microcontroller. Our new design,The Plank has only one axis of force-feedback with limited range of motion. It is being used to explore methods of feeling and directly manipulating sound waves and spectra suitable for live ...

Motion control of truck-mounted concrete pump booms is an important part construction work. The quality the boom movement will affect efficiency and safety operations. To make move quickly steadily, its hydraulic system needs to be improved. In this article, we firstly combine independent metering (IMC) active disturbance rejection (ADRC). that controls meliorated by replacing traditional propo...

This paper proposes a liner active disturbance rejection control (LADRC) method based on the Q-Learning algorithm of reinforcement learning (RL) to six-degree-of-freedom motion an autonomous underwater vehicle (AUV). The number controllers is increased realize AUV decoupling. At same time, in order avoid oversize algorithm, combined with controlled content, simplified Q-learning constructed par...

[Purpose] Early postoperative passive motion exercise after arthroscopic rotator cuff repair remains controversial. To better understand this issue, this study was aimed at evaluating scapular kinematics and muscle activities during passive arm elevation in healthy subjects. [Subjects and Methods] The dominant shoulders of 27 healthy subjects were examined. Electromagnetic sensors attached to t...

This article describes a technique for improved repair of digital flexor tendon laceration. Eight-strand cross-locked cruciate repair using 4-0 caliber double-stranded suture is not bulky and has a smooth configuration for tendon gliding. Additionally, it has sufficient strength for early postoperative active motion exercise.
