Abstract: A real-time gas leakage monitoring system applicable for a vacuum device includes an exhaust device connected to an exhaust end of the vacuum device. In addition to the use of the exhaust device for exhausting a gas from the vacuum device, a mass flow controller can also be connected to the exhaust end to receive the gas exhausted from the vacuum cavity and control a mass flow as a basis to determine a gas leakage setting value, and then a gas leakage detector is used to detect water and oxygen in the gas exhausted from the vacuum cavity. When water and oxygen are detected in the exhaust gas, it indicates a gas leakage status, and a warning signal can be outputted immediately to achieve the real-time gas leakage monitoring effect.

Abstract: The invention discloses a method for screening a therapeutic target of acute radiation-induced gastrointestinal syndrome and use of TIGAR target in the preparation of a medicine for treating radiation-induced gastrointestinal syndrome. The CreERT-loxP transgenic mouse model is used, in which quiescent intestinal crypt stem cells are effectively promoted to proliferate after exposure to high-dose ionizing radiation, to screen a therapeutic target that still has a therapeutic effect for radiation-induced gastrointestinal syndrome 18-24 h after ionizing radiation. Gene splicing occurs in particular cells in the CreERT-loxP transgenic mice only after the injection of tamoxifen, thereby regulating gene expression. The actual situation of initial exposure and then treatment after a nuclear accident is well simulated, so the invention is of great practical significance.

Abstract: A stretchable sensor skin is provided, which is a soft tactile sensor sleeve that can cover large areas of a robot, and is both low-cost and robust. It is made of elastomer molded pouches (referred to as sensor taxels) that when contacted transmit pneumatic pressure to off-board barometric sensors, via stretchable channels. The entirely soft makeup of the sleeve makes it highly conformable to 3D curved geometries of a robot. The stretchable channels mean that it can cover joints without wiring getting caught. The stretchable rubber channels are also inherently more robust than stretchable conductor approaches, and the skin lacks fragile soft-rigid interfaces that has plagued many other sensor skins. The fact that there are no conductive components also makes the skin easy to sanitize and waterproof.
