Abstract: A battery module, and an energy storage system and a control method therefor. When a corresponding preset condition is satisfied, battery modules can be switched in or out of a system by means of the on-off of a main loop on-off control circuit and a bypass on-off control circuit, so that the battery modules currently connected into the system can be adjusted in real time, and thus the battery modules in the system can satisfy the corresponding preset condition one by one, namely achieving the same state (for example, achieving SOC equalization), without causing energy waste. Moreover, a main loop buffer circuit or a bypass buffer circuit is provided in the battery module, so that energy impact generated when the battery module is switched in or cut out of the system can be absorbed.

Abstract: A method for designing a test circuit, includes determining a feature of a to-be-tested circuit based on data representing the to-be-tested circuit. The method further includes determining switch distribution for the to-be-tested circuit based on the feature of the to-be-tested circuit. The switch distribution represents distribution, in a two-dimensional switch matrix circuit, of a plurality of switches that are in a test circuit and that are coupled to a plurality of scan chains of the to-be-tested circuit. The switch matrix circuit includes a plurality of rows and a plurality of columns, any one of the plurality of rows has at least one of the plurality of switches, and any one of the plurality of columns has at least one of the plurality of switches.

Also provided herein is a composition comprising the EVs loaded with or without therapeutic agents and the method of using this composition for treating diseases.

Abstract: A composite structure for a pressure sensor, a pressure sensor, a method of pressure sensing using the pressure sensor, and a method of fabricating a composite structure for a pressure sensor. The method of fabricating a composite structure for a pressure sensor comprises the steps of forming an array of microstructures made from an elastomeric material; and forming a flexible conductive coating on the array of microstructures such that a surface morphology of microstructures is substantially maintained for the coated array of the microstructures; wherein the conductive coating exhibits a Young's modulus that is higher than that of the elastomeric material.
