Abstract: Systems and methods for image processing are provided. The systems obtain a plurality of images of a target subject that are captured consecutively over time. The target subject is injected with tracer and including a target body portion. For each of the plurality of images, the systems generate a sub-image of the target body portion by segmenting the image and transform the sub-image to generate a transformed sub-image in a standard space based on a template image of the target body portion. The standard space includes a plurality of template images of a plurality of body portions. The systems further determine an uptake variation curve indicating a change of tracer uptake in the target body portion over the time based on the transformed sub-images corresponding to the plurality of images.

According to the present disclosure, the basket rotary joint is introduced to adapt to the change of the basket-rotary arm angle before and after the arm-type basket centrifuge works, so that the demand for water, electricity, oil and gas transportation of the centrifuge is met. Therefore, the design for the conduit of the centrifuge-basket part is solidified, and compared with the traditional solution that a high-pressure hose is connected to the basket, the centrifugal acceleration load of the load can be increased to more than 500 g.

Abstract: The present disclosure provides a testis-targeted lycopene (LYC)/ZIF-90 nanocomposite and a preparation method and use thereof, belonging to the technical field of targeted drugs. In the present disclosure, a ZIF-90 metal-organic framework (MOF) material is combined with LYC through aldol condensation; when entering areas of inflammatory response and oxidative stress response, ZIF-90 may disintegrate and collapse in a slightly-acidic environment, releasing the LYC, thereby avoiding easy oxidation of the LYC and improving a bioavailability of the LYC; in addition, the disintegrated and collapsed ZIF-90 may also be utilized by organisms, thus greatly reducing a damage to the organisms. Moreover, the LYC/ZIF-90 nanocomposite is further loaded with follicle-stimulating hormone (FSH).

Abstract: A display apparatus, comprising: a plurality of light sources arranged into an array, angle selection sheets on the light emitting sides of the light sources, and reflective layers on the sides of the light sources away from the angle selection sheets. The angle selection sheets are used for reflecting light rays of a first incident angle range and transmitting light rays of a second incident angle range, wherein an incident angle value corresponding to the first incident angle range is smaller than an incident angle value corresponding to the second incident angle range. The reflective layers can conduct diffuse reflection on the light rays reflected by the angle selection sheets and the light rays re-enter the angle selection sheets, so that light rays of a second incident angle subjected to the diffuse reflection are transmitted while light rays of a first incident angle repeat the described reflection operation.
