Abstract: An artificial intelligence cloud diagnosis platform is provided. A subject sample is scanned to a cloud side, AI on the cloud conducts preliminary detection, and then a doctor carries out diagnosis and rechecking. The artificial intelligence cloud diagnosis improves the diagnosis accuracy, fundamentally solves the problems of insufficient technical experts and non-uniform medical resource distribution in remote areas, greatly improves the diagnosis efficiency, reduces the diagnosis cost, establishes a professional database of the same type of detection samples, and is beneficial to the further research of a disease in the later period.

Abstract: A foldable terminal includes a body, a display screen and a flattening member. The display screen is located on a surface of the body and includes a bendable portion. The flattening member is located between the body and the bendable portion, and configured to apply a force to the bendable portion, so as to flatten the bendable portion when the foldable terminal is in a flattened state.

A combined oscillating system including the acoustic wave device and the living cell or virus exhibits a fundamental frequency and at least one harmonic frequency of the combined oscillating system.

Abstract: A fabrication method for forming polymer nanopillars using an anodic aluminum oxide (AAO) membrane and an imprint process. A substrate is cleaned and a water soluble tape is applied to the substrate to define a coating area. The substrate is spin-coated with a polymer solution and an AAO membrane is placed on top of the coated area on the substrate and turned over whereby a silicon wafer is attached onto the AAO membrane forming an AAO membrane assembly, which is pressed in an imprintor. Then, the AAO membrane assembly is removed from the imprintor, it is disassembled, and the AAO membrane is dissolved in a NaOH solution forming a polymer substrate with nanopillars.
