Abstract: A cell selection method includes receiving, by an access stratum (AS) of a terminal device, first information from a non-access stratum (NAS) of the terminal device. The first information includes identity information of a first public land mobile network (PLMN) to be accessed by the terminal device. The cell selection method also includes determining, by the AS based on the first information, whether to camp on a first candidate cell. The first candidate cell supports the first PLMN. The first candidate cell satisfies a first camping condition. The first camping condition comprises a cell selection criterion and a service requirement. The service requirement is a preset threshold of a parameter reflecting signal quality of a cell.

Abstract: Provided are serum-stable nanoparticles comprising porphyrin-phospholipid conjugates. Also provided are compositions comprising the nano-particles. The nanoparticles can comprise cargo such as therapeutic agents and/or diagnostic agents (e.g., imaging agents) and be used in drug delivery methods based on NIR stimulated cargo release.

Abstract: A multi-chamber tire, comprising an outer layer portion and an flexible ring body in an annular fashion; the outer layer portion is arranged on the external side of the flexible ring body; the flexible ring portion is provided with chambers arranged around the flexible ring portion; the chambers are provided with a plurality of partitioned gussets; each of the partitioned gussets is arranged around the flexible ring body and extends along the axial and radial directions, and the plurality of partitioned gussets are arranged around the flexible ring body alternately, dividing the chambers into a plurality of isolating chambers isolated from each other.

Abstract: Disclosed are an electric vehicle chassis and an electric vehicle using the electric vehicle chassis. The electric vehicle chassis comprises a frame system (2), a steering motor damping system (13), a wheel system (12), a steering system (3) and a braking system (14), wherein the wheel system (12) comprises a left front wheel (121) using a hub motor, a left rear wheel (123) using a hub motor, a right front wheel (122) using a hub motor, and a right rear wheel (124) using a hub motor; and the steering motor damping system (13) comprises a left front steering damping motor (131), a right front steering damping motor (133), a left rear steering damping motor (135) and a right rear steering damping motor (137). Driving the wheels with the hub motors can omit a traditional mechanical transmission system, so as to simplify the structure of the chassis, reduce the weight of the chassis, and also reduce the mechanical transmission loss, thereby improving the power utilization efficiency.
