Abstract: A heat dissipation system for a high-speed train running in a low-vacuum tube is provided. Component groups that provide power and resistance for the movement and stop of a train are provided at a periphery, close to the train, in a low-vacuum tube. The component group is provided with a group A cooling assembly. The group A cooling assembly includes a group A cooling-type heat exchanger and/or a group A nozzle assembly attached to the back of the component group. Since the friction between the train running at high speed and the air in the low-vacuum tube and the operation of the key equipment in the low-vacuum tube will generate a lot of heat, the group A cooling assembly in the component group in the low-vacuum tube exchanges the heat with the air in the low-vacuum tube.

Abstract: This invention relates to a closed-loop adaptive AC stimulation neural network control method and system, involving the technical field of AC stimulation neural regulation. This system is composed of an individualized navigation module, AC stimulation module, EEG acquisition module and adaptive coupling module. After the magnetic resonance image and functional magnetic resonance image of the regulation object are input into the individualized navigation module, the functional connectivity network is generated to finalize regulatory targets. The position of stimulating electrodes and the magnitude of the stimulating current are determined according to the target to be regulated. The stimulating frequency is determined according to the EEG of the regulation object and then input into the AC stimulation module for regulation.

Abstract: Provided is a device which obtains information for verifying onset of dementia while suppressing individual differences between subjects. The device includes a stimulus provision unit 12 which provides a subject H with one of two alternatively selectable selection items as a stimulus including at least one of audio information and visual information a plurality of times, a measurement unit 13 which measures a response time from the provision of the stimulus to the reception of the responses from the subject H, an average time computation unit 14 which calculates an average value of the response times, and a data creation unit 17 which creates data in which the average value of the response times for the specified subject H is compared with the previously prepared average value of the response times.
