Abstract: A SOI wafer is disclosed. The SOI wafer may be characterized by surface roughness of a top silicon layer of the SOI wafer is less than 4 ?, thickness uniformity of the top silicon layer is within ±1%, and a total number of particles on a surface of the top silicon layer of the SOI wafer, measured with setting of 37 nm of SPx detection threshold, is less than 100.

Abstract: A battery cell includes: a shell, including a first wall; an electrode assembly, disposed inside the shell; and a terminal assembly, including an electrode terminal and an elastic member. The electrode terminal includes a fixed portion for electrical connection with the electrode assembly and a movable portion for electrical connection with a current collecting component. The fixed portion is fixedly disposed on the first wall. The movable portion is movably disposed on the first wall, and has a first position in contact with the fixed portion and a second position separated from the fixed portion. The elastic member is used for applying elastic force to the movable portion to maintain the movable portion in the first position. The movable portion is configured to move from the first position to the second position against the elastic force when internal pressure of the battery cell reaches a threshold.

Abstract: Methods and systems for image analysis are provided, and in particular for identifying a set of base-calling locations in a flow cell for DNA sequencing. These include capturing flow cell images after each sequencing step performed on the flow cell, and identifying candidate cluster centers in at least one of the flow cell images. Intensities are determined for each candidate cluster center in a set of flow cell images. Purities are determined for each candidate cluster center based on the intensities. Each candidate cluster center with a purity greater than the purity of the surrounding candidate cluster centers within a distance threshold is added to a template set of base-calling locations.

Abstract: A method for recovering lithium from a lithium-containing solution is provided. A lithium-containing solution with an adjusted pH value or an unadjusted pH value is mixed with a meta-aluminate, and the pH value is adjusted to weak acid/neutral, so that lithium can be separated from the lithium-containing solution in the form of a precipitate of LiaX·2Al(OH)3·nH2O. Then, the precipitate is converted into a lithium adsorbent of (1-m)LiaX·2Al(OH)3·nH2O and a LiaX-containing filtrate through desorption of lithium. High-purity Li2CO3 is obtained by performing precipitation of lithium on the LiaX-containing filtrate.

Abstract: A lithium ion adsorbent includes a material having a chemical formula of LiCl.2Al(OH)3.nH2O. n is an integer from 1 to 3, a specific surface area of the lithium ion adsorbent is 20-36 m2/g, an average pore diameter of the lithium ion adsorbent is 20-35 nm, a total pore volume of the lithium ion adsorbent is 0.15-0.32 mL/g, a D10 of the lithium ion adsorbent is 3-12 ?m, a D50 of the lithium ion adsorbent is 12-22 ?m, and a D90 of the lithium ion adsorbent is 20-40 ?m.

Abstract: An online system receives information describing events corresponding to actions associated with a third party system performed by an individual. The received information describes event types and times at which the events occurred. The online system generates nodes of a directed graph associated with the third party system, in which each node corresponds to an event type. For each event, a node count associated with a node corresponding to the event's type is incremented by the online system. Pairs of consecutively occurring events are identified based on times at which the events occurred and an edge describing each transition from one event to another is generated by the online system. The online system determines an edge count for each transition indicating a number of edges describing the transition as well as a sequential order of event types based on one or more node counts and one or more edge counts.

Abstract: The present disclosure discloses a method, apparatus, and system for sharing a virtual reality (VR) viewport.

Abstract: The present invention discloses a networked communication system. The networked communication system comprises a multipoint control unit (MCU) operating a MCU server to receive and process multimedia data transmitted from a plurality of networked communication devices functioning as clients of the MCU. The multimedia data transmitted from each of the clients further include meta-data identifying each of the clients transmitting the multimedia data and the MCU server further processes the multimedia data according to the meta-data to position the multimedia data in a plurality of frames for real-time multiple party display for each of the clients.

Abstract: A video player instance may be prioritized and decoding and rendering resources may be assigned to the video player instance accordingly. A video player instance may request use of a resource combination. Based on a determined priority a resource combination may be assigned to the video player instance. A resource combination may be reassigned to another video player instance upon detection that the previously assigned resource combination is no longer actively in use.

Abstract: Disclosed is a method for video monitoring based on Universal Plug and Play (UPnP), comprising the steps of: a camera device saves an improved Digital Media Server (DMS) function; after receiving the request transmitted by a Digital Media Control (DMC) device, for obtaining the video stream, the camera device analyzes the request for obtaining video stream by the improved DMS function and then starts camera shooting. Also disclosed is a device and system for video monitoring based on UPnP. The present invention can provide function of real-time video monitoring in the UPnP network architecture.
