Abstract: A lumen stent (100) and an implant are provided. The lumen stent includes a tubular body (11), an inner branch (12) and an outer branch (13) which are respectively communicated with the tubular body (11). The tubular body (11) includes a first body segment (111), a tapered segment (112) and a second body segment (113) which are connected in sequence. The tapered segment (112) is provided with an outer branch window (110b) and an inner branch window (110a). The proximal end of the outer branch (13) is connected to the outer branch window (110b). The distal end of the inner branch (12) is connected to the inner branch window (110a). The area of the inner branch window (110a) is larger than that of the outer branch window (110b).

Abstract: One or more implementations of the present specification provide an invoice access method and apparatus based on a blockchain, and an electronic device. The method includes: generating first ciphertext data by encrypting plaintext data of the target invoice based on a first key corresponding to an invoice issuer; generating second ciphertext data by encrypting the plaintext data of the target invoice based on a second key corresponding to an invoice receiver; adding the first ciphertext data and an user identifier of the invoice issuer to the blockchain as related to one another; and adding the second ciphertext data and an user identifier of the invoice receiver to the blockchain as related to one another.

Abstract: A method and an apparatus for generating an image processing interface, a device, and a storage medium, including: receiving a first instruction, where the first instruction is used to characterize an image parameter of a target image; determining an image template corresponding to the first instruction, where the image template is used to characterize a processing flow of the target image; and generating a processing interface of the target image according to the image template. Since the image template standardizes the process and steps of image processing, the specific operation steps for generating an image processing interface are simplified, while standardizing the generated image processing interface, reducing the using and maintenance cost of the image processing interface, and improving the security of the image processing interface.

Abstract: Methods, systems, apparatuses, and computer-readable storage media for interactions based on in-vehicle digital persons are provided. In one aspect, a method includes: acquiring a video stream of a person in a vehicle captured by a vehicle-mounted camera, processing at least one frame of image included in the video stream to obtain one or more task processing results based on at least one predetermined task, and performing, according to the one or more task processing results, at least one of displaying a digital person on a vehicle-mounted display device or controlling a digital person displayed on a vehicle-mounted display device to output interaction feedback information.

Abstract: The present application relates to a vehicle door control method, apparatus, and system, a vehicle, an electronic device, and a storage medium. The method comprises: controlling an image acquisition module disposed on a vehicle to acquire a video stream; performing face recognition on the basis of at least one image in the video stream to obtain a face recognition result; determining, on the basis of the face recognition result, control information corresponding to at least one vehicle door of the vehicle; if the control information comprises controlling any vehicle door of the vehicle to open, obtaining state information of the vehicle door; if the state information of the vehicle door is Not Unlocked, controlling the vehicle door to unlock and open; and/or, if the state information of the vehicle door is Unlocked And Unopened, controlling the vehicle door to open module.
