Abstract: This specification presents sheets including graphitic materials, including sandwich structures, thermoformed or wet-formed single layer or multilayer structures of graphitic materials, and methods of forming a layer of graphitic material. In accordance with one aspect, the specification presents a multi-layer structure comprising a core layer having a core density between 0.01 and 1 g/cm3; and a skin layer covering the core layer, the skin layer having at least 10% by weight of a graphitic material, the graphitic material having one or more of graphene oxide, reduced graphene oxide, graphene, graphite oxide, reduced graphite oxide and graphite, the skin layer having a skin density of between 0.5 and 2 g/cm3 , a thickness ratio of the skin layer to the core layer being of between 1:1000 and 1:1.

Abstract: Each of a plurality of clients encodes events as respective vectors and cooperatively choose a joint key. Each client then encrypts its event vector(s) using the joint key to form secret shares of a fixed value and then sends the encoded, encrypted vectors to a service-providing system that selects pairs of the vectors and determines a comparison value from a reconstruction of the secret shares. When the comparison value meets a predetermined criterion, the service-providing system generates a message indicating similarity between the selected pairs of the vectors. The service providing system thus determines a degree of similarity between the events without requiring knowledge of raw data about the events.

Abstract: The present disclosure provides a circuit board, including a substrate on which a first conductive layer and an electronic device are disposed, wherein the first conductive layer is disposed on a first surface of the substrate, and wherein a bottom end of the electronic device is disposed on the first conductive layer through the substrate. The present disclosure provides a display device.

Abstract: A terminal device and a method for controlling the terminal device are provided. The terminal device includes a terminal body; a pressure sensor arranged at a side of the terminal body; a control circuit, connected with an output terminal of the pressure sensor, and configured to perform a preset operation when a pressure detected by the pressure sensor is not smaller than a preset pressure threshold.
