Based on the embodiments in the present disclosure, feature data of a reference frame of a first image frame is acquired, and the position of a tracking target in the first image frame is determined based on the feature data of the reference frame.

Abstract: In a service deployment method performed by a function management platform that includes a function scheduler and a function executor manager, the function scheduler receives a function call request that carries a function identifier, selects an available host based on resource pool information of a tenant, and sends a function instance creation request to the function executor manager. The function executor manager receives the function instance creation request, selects the host corresponding to the host identifier from the resource pool of the tenant, and creates a function executor corresponding to the function identifier on the host.

Abstract: The present disclosure provides a loading apparatus and a physical vapor deposition (PVD) apparatus. The loading apparatus includes a pedestal configured to support a workpiece; and a first support member placed on the pedestal and configured to push up a cover ring when the pedestal is at an operation position to prevent an overlapping portion of a cover ring and the workpiece from contacting each other. In the loading apparatus and the PVD apparatus, the first support member supports the cover ring, such that the cover ring does not contact the workpiece, thereby reducing stress forces on the workpiece by external components.

Abstract: Target tracking methods and apparatuses, electronic devices, and storage media are provided. The method includes: obtaining features of a plurality of reference images of a target image; determining a plurality of initial predicted positions of a tracking target in the target image based on the features of the plurality of reference images; and determining a final position of the tracking target in the target image based on the plurality of initial predicted positions.

Abstract: The present disclosure provides a deposition apparatus, including a first chamber, a second chamber and a third chamber. The first chamber is configured to load a substrate. The second chamber is configured to provide a high temperature environment in which a degas process and a sputtering process are performed on the substrate. The third chamber is provided between the first chamber and the second chamber. The third chamber is configured to transfer the substrate from the first chamber to the second chamber via the third chamber.

Abstract: A heating device and a heating chamber are provided, comprising a base plate (21), at least three supporting columns (22) and a heating assembly, where the at least three supporting columns are arranged vertically on the base plate and are distributed at intervals along a circumferential direction of the base plate Top ends of the at least three supporting columns form a bearing surface for supporting a to-be-heated member (23). The heating assembly includes a heating light tube (24) and a thermal radiation shielding assembly, where the heating light tube is disposed above the base plate and below the bearing surface. A projection of an effective heating area formed by uniform distribution of the heating light tube on the base plate covers a projection of the bearing surface on the base plate. The thermal radiation shielding assembly shields heat radiated by the heating light tube towards surroundings and bottom.

Abstract: Methods, devices and systems for managing calendar data are provided. The method includes: receiving shared calendar data distributed by a first calendar client terminal, the shared calendar data being obtained by the first calendar client terminal modifying original calendar data displayed on the first calendar client terminal; and pushing the shared calendar data to a second calendar client terminal so that the second calendar client terminal can update second original calendar data with the shared calendar data. Here the second original calendar data is obtained by the second calendar client terminal adding corresponding event data to a designated date page on a calendar interface displayed on the second calendar client terminal.

Abstract: A biodegradable common bile duct stent and the method for preparing thereof are provided. The stent is made of biodegradable polymeric material with incorporation of X-ray opaque components. The stent adapts to the anatomical shape of the CBD or it can be sutured together with the wall of the bile duct. After placing the stent in the duct, it maintains its position and does not slip. The circular tube of the stent being suitably sized and having multiple ring-shaped protruding rims at the outer wall and/or with larynx structure, leakage and outflow of the bile are thereby prevented. It can be manufactured by a conventional injection-molding or an extrusion-blowing technique. In surgical operation on the bile duct, the stent can replace the T-tube which is conventionally used to support the duct and guide bile drainage.
