Abstract: The present invention generally relates to systems and methods for imaging or determining nucleic acids, for instance, within cells. In some embodiments, the transcriptome of a cell may be determined. Certain embodiments are directed to determining nucleic acids, such as mRNA, within cells at relatively high resolutions. In some embodiments, a plurality of nucleic acid probes may be applied to a sample, and their binding within the sample determined, e.g., using fluorescence, to determine locations of the nucleic acid probes within the sample. In some embodiments, codewords may be based on the binding of the plurality of nucleic acid probes, and in some cases, the codewords may define an error-correcting code to reduce or prevent misidentification of the nucleic acids. In certain cases, a relatively large number of different targets may be identified using a relatively small number of labels, e.g., by using various combinatorial approaches.

Abstract: A hydrogel for cell-laden bioprinting, bioink, and a preparation method and an application thereof, relates to the technical field of biomedical polymer hydrogels. The hydrogel for cell-laden bioprinting is polymer gel formed by adding a cell-specific material into a matrix of alginate and gelatin and crosslinking and curing, wherein the cell-specific material is polypeptide selected according to different laden cells. The structures printed using the hydrogel may have the advantages such as adjustable mechanical properties, adjustable porosity, high biocompatibility, high printing accuracy, and high customizability, which may widely support the printing of human tissues and organs such as spinal cord, cartilage, and heart, and has good prospects for applications in tissue repair, organ transplantation and so on.

The handover method includes: receiving cell information of a second cell sent by a second network element, wherein the second cell is a cell managed by the second network element, and the cell information includes predicted cell load information of the second cell; and sending a handover instruction to a terminal in a case where the cell information satisfies a preset condition, wherein the handover instruction is used for instructing the terminal to perform handover to the second cell, and the case where the cell information satisfies the preset condition at least indicates that the predicted cell load information of the second cell is lower than a configured first threshold.

Abstract: A camera module comprises a supporting member for supporting a sensor chip to move relative to a lens for correcting camera shake, a plurality of bulges is provided between the supporting member and a bottom plate. The bulges provide a reduced resistance to sliding on the supporting member. An electronic device using the module is also disclosed.

Abstract: The present disclosure provides a preparation method of a catalyst slurry for a fuel cell membrane electrode assembly (MEA), including the following steps: preparing a slurry mixture with a catalyst, a dispersing solvent, an ionomer, a thickener, and a surfactant according to a certain mass ratio; subjecting the slurry mixture to pre-dispersion several times in an ultrasonic disperser and a high-shear emulsifying machine successively, to obtain a slurry pre-dispersion; and conducting dispersion on the slurry pre-dispersion in a high-pressure homogenizer to obtain the catalyst slurry. In the present disclosure, components of the catalyst slurry and a dispersion process are optimized and innovated, to construct a more effective three-phase interface. The MEA prepared according to the present disclosure has a significantly improved performance and reduced slurrying time; and is thus suitable for mass production.

Abstract: A card edge connector with an insulative housing includes opposite longitudinal side walls along a longitudinal direction with a receiving slot therebetween in a transverse direction. Each side wall forms a plurality of passageways. A plurality of contacts are respectively received within the corresponding passageways. Each contact includes a retaining section, a contacting section extending from the retaining section into the receiving slot, and a leg extending downwardly from the retaining section out of the housing. Each contact is further equipped with an auxiliary spring beam with an additional contacting section extending into the receiving slot. The contacts are initially linked to a single contact carrier strip so as to be simultaneously inserted into the corresponding passageways, respectively.
