Abstract: A robot for interacting with a target object includes a robotic manipulator, a calibrating image, a camera and a processor. The robotic manipulator corresponds to a robotic manipulator coordinate. The calibrating image is disposed on the robotic manipulator. The camera corresponds to a camera coordinate and for shooting the target object and generating a picture. The processor is configured to move the robotic manipulator such that the calibrating image moves towards the target object and enters the picture. The processor records robotic manipulator coordinate datasets and camera coordinate datasets of the calibrating image as the calibrating image moving towards the target object, and uses the robotic manipulator coordinate datasets and the camera coordinate datasets to execute a hand-eye calibrating algorithm to obtain a calibrated mapping between the camera coordinate and the robotic manipulator coordinate.

Abstract: Embodiments are directed to a method for minimizing electrostatic charges in a semiconductor substrate. The method includes depositing photoresist on a semiconductor substrate to form a photoresist layer on the semiconductor substrate. The photoresist layer is exposed to radiation. The photoresist layer is developed using a developer solution. The semiconductor substrate is cleaned with a first cleaning liquid to wash the developer solution from the photoresist layer. A tetramethylammonium hydroxide (TMAH) solution is applied to the semiconductor substrate to reduce charges accumulated in the semiconductor substrate.

Abstract: A software developer proxy tool accesses microservice applications for a software development project by connecting the developer proxy tool to a common port on a computer network. The tool implements software and hardware to register a plurality of the microservice applications on connection ports that connect to the developer proxy tool at an address for the common port. Data requests among the microservices are handled by the developer proxy tool via the common port. The tool sequentially queries selected microservice applications on the respective connection ports to determine availability for completing a request. The tool receives responses back from microservices and directs the responses back to the requesting program. Failed requests trigger use of remote or third party microservice applications that may be available over an internet connection.

A bottom semiconductor structure is positioned below the second source/drain region and in contact with the semiconductor layer.

Abstract: The present invention provides an alcohol extract of Ajuga taiwanensis Nakai ex Murata exhibits significant effects on inhibiting the senescence in human WI-38 lung fibroblasts and human dermal fibroblasts. Moreover, the alcohol extract of A. taiwanensis is able to suppress the expression of the cofilin-1, a protein involved in actin dynamics and cell morphology and found to be increased in senescent cells. Suppression effect of cell senescence by this herb extract is more efficient in mild concentration without over-inhibition of cell viability and growth.
