Abstract: The present disclosure provides a method for treating liver cirrhosis by using a composition including mesenchymal stem cells, extracellular vesicles produced by the mesenchymal stem cells, and growth factors. The composition of the present disclosure achieves the effect of treating liver cirrhosis through various efficacy experiments.

Abstract: A surgical device has a housing having a hook portion at a distal end of the housing, an opening radially penetrating between the hook portion and the housing; a grasping structure comprising a rotating member rotatably positioned within the hook portion, having a notch radially recessed on a periphery of the rotating member, at least a portion of the notch corresponding to at least a portion of the opening; and reciprocating motion of an actuator along the axis for rotating the rotating member such that the open end of the notch is selectively connected to or misaligned with the open end of the opening.

Abstract: An ultrasonic surgical holder has an assembly portion connected to at least one operating portion having an end extending toward an axial direction. An operating space is formed between the assembly portion and the operating portion. The assembly portion is designed for detachable assembling with an ultrasonic probe. The operating portion features a detachable structure that includes a surgical device to aid the operator in positioning, marking, and determining the location of the surgical operation on the body part's surface during the subsequent operation.

Abstract: A social distance determination system includes a first electronic device. The first electronic device is configured to establish a first communication link with a wireless base station, detect the first communication strength of the first communication link, generate a first conversion vector according to the first communication strength, and perform a similarity calculation on the first conversion vector and a second conversion vector to obtain a similarity result.

Abstract: A method, a system, and a computer-accessible recording medium for motion recognition based on an atomic pose are provided. A video frame including a live body is obtained. An atomic pose feature value is generated by analyzing the live body in the video frame. A hash value of the atomic pose is generated by executing a hash function according to the atomic pose feature value. The live body executing a specific motion is recognized by comparing the atomic pose hash value.

Abstract: A handle of a walker capable of determining use intent includes at least one movable member; fixed members slidingly coupled to the at least one movable member respectively; and pressure sensors disposed at joints between the fixed members and the at least one movable member respectively.

Abstract: A method of signal processing for handling a digital signal outputted by an analog-to-digital converter includes determining a candidate interval corresponding to each of multiple sampling points in a sampling space of the digital signal, wherein the candidate interval is one of multiple candidate intervals, calculating numbers of sampling points corresponding to each one of the multiple candidate intervals to determine a delegate candidate interval, and calculating a delegate value of the sampling space according to a number of sampling points corresponding to the delegate candidate interval and values of the sampling points corresponding to the delegate candidate interval.
