The application discloses a micro-fluidic chip and a method for recovering nucleic acids with different fragment sizes. The method can realize recovery of nucleic acids with different fragment sizes by repeatedly washing and recovering magnetic beads through the micro-fluidic chip. The method can improve the overall nucleic acid recovery effect by adjusting the adding concentration of the magnetic beads and PEG salt and the washing times, and can distinguish and control the nucleic acid length, and all the nucleic acids with different fragment lengths can be obtained by continuously adjusting the concentration. Moreover, the method can realize small volume, high throughput and automation.

This application discloses a method and apparatus for edge location detection, a self-moving device, a storage medium, and a program product. The edge location detection method includes: performing at least one region update operation during the movement of the self-moving device to update the target region; if a target region update is detected, updating the target map information to the attribute information of each first location point; if, based on the target map information, it is determined that among the multiple first location points, at least one target location point's height information conforms to a preset height range, determining the edge location based on at least one target location point. This method can reduce the storage space occupied by the self-moving device's map storage during edge location identification.

The present application relates to a kind of low-dose X-ray CT image-oriented noise removal method, by the method of semi-supervised contrast learning, low-dose CT image is removed noise by teacher-student consistency network and prior knowledge transfer method, reduce effective information loss, retain more detail information, to provide high-quality input data for subsequent image reconstruction, realize the reconstruction of high-quality CT image under low-dose X-ray condition.Compared with the traditional method based on low-pass filter or image statistics, the present application can better remove noise, so that the image after denoising is more real and clear, and by adjusting its network structure and hyperparameter, it can be applied to various low-dose CT image denoising tasks, including different scanning modes, different organs, etc., with high versatility and scalability.

The present application relates to the technical field of waterborne polyurethane materials, and particularly relates to a low VOC waterborne PU foam pad and a preparation method thereof. The foam pad is formed by foaming and curing of a waterborne polyurethane dispersion, and two types of aldehyde-trapping sites are simultaneously introduced into the same porous framework, i.e. an amidoxime group formed by post-conversion of a nitrile group precursor by hydroxylamine, and an aminooxy group obtained by coupling and deprotection of T-BOC-aminooxy-diglycol-amino through a carboxyl anchoring site under an EDC and NHS activation system; and a water-dispersible blocked polyisocyanate crosslinking agent is used to form a crosslinking network by pyrolytic deblocking, so as to achieve rapid capture and durable retention of aldehydes such as formaldehyde and acetaldehyde under water washing and humid heat conditions, and simultaneously help to reduce VOC emission of the material.
