Abstract: A metal product includes a metal substrate, at least one first hole, at least one second hole, and at least one third hole. The first hole is formed in a surface of the metal substrate. The second hole is formed in at least one of a portion of the surface of the metal substrate without the first hole and an inner surface defining the first hole. The third hole is formed in at least one of a portion of the surface of the metal substrate without the first hole and without the second hole, a portion of the inner surface defining the first hole without the second hole, and an inner surface defining the second hole. The first, second, and third holes enhance a bonding strength between the metal product and a material product. The disclosure also provides a metal composite and a method for manufacturing the metal product.

Abstract: This application provides techniques of generating interactive videos. The techniques comprise obtaining an original video, creating an interactive track for the original video to obtain an initial video, and adding an interactive component to the interactive track; and generating an interactive video by rendering at least one interactive video frame and other video frames of the initial video based on the interactive component. In this way, an interactive video with an interactive capability can be generated without additionally adding a data channel to implement an interaction function, thereby reducing processing load of a terminal and reducing resource consumption of the terminal.

Abstract: Embodiments of the present disclosure relate to compositions and kits for use in sequencing by synthesis to improve fluorescent signal intensity and reduce signal decay caused by short wavelength light source during the imaging events. Methods of sequencing using the compositions and kits described herein are also provided.

Abstract: A sequencing kit includes a plurality of particles and a flow cell. The plurality of particles includes a primer set attached to a surface of each of the plurality of particles; and a flow cell surface attachment mechanism attached to the surface of each of the plurality of particles. The flow cell surface attachment mechanism is selected from the group consisting of a capture primer, an alkene, an alkyne, biotin, and a charged polymer. The flow cell includes a plurality of chemical pads that are spatially separated from one another on a substantially flat substrate surface, each of the chemical pads including chemistry to attach to the surface attachment mechanism.

Abstract: An example of a flow cell includes a substrate having depressions separated by interstitial regions. First and second primers are immobilized within the depressions. First transposome complexes are immobilized within the depressions, and the first transposome complexes include a first amplification domain. Second transposome complexes are also immobilized within the depressions, and the second transposome complexes include a second amplification domain. Some of the first transposome complexes, or some of the second transposome complexes, or some of both of the first and second transposome complexes include a modification to reduce tagmentation efficiency.

Abstract: Provided in one example is a method of manufacturing a flowcell that includes: forming a core layer, the core layer disposed between a substrate and a nanowell layer, the nanowell layer having nanowells to receive a sample, the core layer having a higher refractive index than the substrate and the nanowell layer; and forming a grating to couple light to the core layer.

Abstract: A capacitor drop power supply circuit for supplying power to a load has a switch configured to alter a configuration of the power supply circuit to reduce input current of the power supply circuit. The switch is operable by the load to alter the configuration when the load enters a power save mode. The switch is operable to alter the configuration of the power supply circuit between a first configuration having a first current path through the power supply circuit in a first current direction, and a second configuration having a second current path through the power supply circuit in the first current direction. The switch changes the power supply circuit between the first configuration and the second configuration when the load enters a power save mode.
