Abstract: This application relates to the technical field of connection structures, and in particular to a quick connector, which is characterized in that it comprises a connector, that serves as an installation body and is used to connect and communicate multiple pipes to ensure that liquid flows inside the connector; a quick-connect assembly is arranged at at least one end of the connector; wherein the quick-connect assembly comprises a spring assembly and a pressing ring which are placed in sequence from the inside to the outside of the connector; the spring assembly is used to clamp a water pipe to be connected, and the spring assembly comprises a spring sheet, which extends toward the axis of the pressing ring and extends out of the inner ring of the pressing ring; the pressing ring is suitable for moving along the axis direction of the connector to push the spring sheet to extend and retract.

Abstract: An antibody-drug conjugate targeting HER2, HER3 and EGFR, and a pharmaceutically acceptable salt, a hydrate, a solvate or an isotopically labelled analogue thereof, the use thereof, and a preparation method therefor.

Abstract: A method and an apparatus for training a transferable vision transformer (TVT) for unsupervised domain adaption (UDA) in heterogeneous devices are provided. The method includes that a heterogeneous device including one or more graphic processing units (GPUs) loads multiple patches into the TVT which includes a transferability adaption module (TAM). Furthermore, a patch-level domain discriminator in the TAM assigns weights to the multiple patches and determines one or more transferable patches based on the weights. Moreover, the heterogeneous device generates a transferable attention output for an attention module in the TAM based on the one or more transferable patches.

Abstract: Aspects of the current subject matter can include systems, devices and methods related to embodiments of a respiratory valve apparatus. The respiratory valve apparatus can include a first port configured to couple to a ventilator, a second port configured to couple to a resuscitation bag or a transport ventilator, a third port configured to couple to an endotracheal tube, and a piston within a housing of the respiratory valve apparatus. The piston can include a first flow pathway that allows fluid flow between the first and third ports when in the first position and a second flow pathway that allows fluid flow between the second and third ports when in a second position. The piston can prevent fluid flow between the second and third ports when in the first position and prevent fluid flow between the first and third ports when in the second position.

Abstract: An improved staining method is described for staining a biopolymer such as a peptide, a protein, an RNA, a DNA, an oligosaccharide or a complex containing a peptide, a protein, an RNA, a DNA, or an oligosaccharide in a matrix. The method includes the step of moving a staining reagent into the matrix using an electric force. The staining time can be dramatically reduced relative to conventional technologies. The improved staining method can particularly be used, for example, to stain proteins after gel separation. Other related methods and related kits are also described.

Abstract: In a switch mode power supply, a circuit and method for switching between an internal clock and an external synchronization clock when a stable external clock has been detected, and for switching back to operating the power supply using said internal clock when a predetermined number of sequential external clock pulses exceed a predetermined switching period dropout threshold or are otherwise missing. In one embodiment, a power system comprises a plurality of power supplies connected in parallel to a common load and where each power supply is synchronized to the external clock when a stable external clock has been detected by each.

Abstract: A compressor unit including a compressor housing, a compressor impeller, a gas diffuser channel, a cylinder-shaped rotating diffuser wall, and a supporting device. The compressor housing includes an air inlet and an air collection channel. The compressor impeller is installed in the compressor housing. The gas diffuser channel is disposed between the compressor impeller and the air collection channel and connected to the air collection channel. The cylinder-shaped rotating diffuser wall is disposed between an inner wall of the compressor housing and the compressor impeller and rotates in the same direction as the compressor impeller. The supporting device is disposed in the compressor housing to support the cylinder-shaped rotating diffuser wall. The compressor unit has high response speed, large air inlet flow, and high efficiency.

Abstract: An apparatus for forming a surface reservoir to hold a sample for a desirable period of time is described. The apparatus contains a platform, a solid surface disposed onto the platform, and an assembly of a bottomless vessel mounted on the solid surface. Also described is an apparatus that forms an array of surface reservoirs on a solid surface when multiple bottomless vessels are used, which can be used for high throughput applications.
