Abstract: An aortic valve conduit with limited expansion is disclosed which includes an aortic valve preliminary conduit attached with a collagen fiber coating. The aortic valve preliminary conduit includes a proximal conduit, a valve connecting conduit, and a distal conduit. A preparation method thereof is also disclosed. The aortic valve conduit may be used for Bentall type surgery. After an artificial biological valve dysfunctions, the aortic valve conduit disclosed herein provides conditions for placing a replacement artificial biological valve with a same size as the original (dysfunctional) valve in an interventional mode. After the biological valve dysfunctions, the replacement valve with the same size as the original valve can be placed in an interventional mode, and a patient's chest does not need to be opened to replace the biological valve with the same size replacement.

Abstract: According to embodiments of the disclosure, a method, apparatus, device, and storage medium for image processing are provided. In this method, an image sensing unit array of a camera is divided into a set of full processing units and at least one set of partial processing units based on a characteristic of a lens of the camera, and/or a current gazing point of a user of the camera. Within at least one stage of a plurality of stages of an imaging process using the camera, a processing load associated with at least some units of the partial processing units is reduced.

Abstract: A multi-layer low-pass filter is used to filter a first frame of video data representing at least a portion of an environment of an individual. A first layer of the filter has a first filtering resolution setting for a first subset of the first frame, while a second layer of the filter has a second filtering resolution setting for a second subset. The first subset includes a data element positioned along a direction of a gaze of the individual, and the second subset of the frame surrounds the first subset. A result of the filtering is compressed and transmitted via a network to a video processing engine configured to generate a modified visual representation of the environment.

Abstract: Embodiments of the present application provide an image display method, apparatus, device and storage medium. The method comprises: determining, according to a pixel brightness of a to-be-displayed image, a corresponding adaptive brightness mapping relationship that makes a difference between the pixel brightness of a non-low-brightness pixel area of the to-be-displayed image after being displayed through an optical imaging system and an ideal brightness of the non-low-brightness pixel area that is not displayed through the optical imaging system less than a preset brightness difference; and transforming the pixel brightness of the to-be-displayed image according to the adaptive brightness mapping relationship, and displaying the transformed to-be-displayed image through the optical imaging system.

Abstract: Provided an image compression and transmission method and apparatus, an electronic device and a storage medium. An image to be processed is divided into a first area image located at a center of the image and a second area image surrounding an outer side of the first area image, and an inner contour of the second area image is adjacent to the first area image. The second area image is compressed based on compression information to generate a third area image, the compression information indicating a compression mode of the second area image, an inner contour of the third area image is adjacent to the first area image, and a resolution of the third area image is smaller than that of the second area image. A compressed image is generated based on the third area image, and the compressed image is sent to a display unit for displaying.

Abstract: A composition and a method are provided for improving number and/or function of muscle satellite cells, and/or treating or preventing muscle atrophy in a subject in need thereof. Such a composition comprising a homogenous polysaccharide or a derivative thereof, or a pharmaceutically acceptable ester or salt thereof, or a pharmaceutically acceptable solvate thereof, or any combination thereof, and a pharmaceutically acceptable excipient. The homogeneous polysaccharide consists essentially of arabinose, galactose, rhamnose, and galacturonic acid as monomer units. Such a method comprises administrating an effective amount of such a composition into a subject in need thereof.

Abstract: A method may include receiving input for a multiwell structure and subsurface target locations, where the multiwell structure includes slots; generating, based at least in part on the input, a position for the multiwell structure, slot-well assignments for the slots, and well trajectories, where each of the well trajectories extends from an assigned one of the slots to one or more of the subsurface target locations; and outputting a set of specifications for the position for the multiwell structure, the well trajectories, and an order for drilling the well trajectories.

Abstract: An electronic device that includes a display and an eye tracker configured to collect eye tracking data regarding a gaze of one or more of a user's eyes across the display is disclosed herein. The electronic device includes processing circuitry that is operatively coupled to the display and configured to foveate one or more areas of the display according to the eye tracking data. If the eye tracking data input is lost, the processing circuitry is configured to recover from the loss of eye tracking data by changing one or more aspects of the foveated areas (e.g., size, resolution, etc.) until a threshold is satisfied. As time elapses since loss of eye tracking, the foveated areas move toward a center or a salient region of the display.
