A disassembly and assembly hole is provided on the housing located between the at least two third accommodating cavities arranged at intervals, and the disassembly and assembly hole is communicated with the first accommodating cavity and is configured for the disassembly and assembly of the discharge device. By arranging the disassembly and assembly hole, the disassembly and assembly steps of the discharge device are simplified, meeting the need of rapid testing of the compression device. By arranging the discharge device with a stepped piston, the service life of the discharge device is increased and the discharge device has higher reliability and consistency. By arranging a tree topology or net topology, the flow resistance of gas may be reduced and the refrigeration efficiency may be improved, achieving multi-stage refrigeration.

The method includes: normalizing acquired ship motion historical data under a certain degree of freedom to form a ship motion original time series; dividing the original time series into a training set and a test set; reconstructing a data set according to the training set and the test set, and establishing a long short-term memory (LSTM) network model for prediction to obtain prediction results of the first ship motion; reconstructing a data set, and establishing a Gaussian process regression (GPR) model for prediction to obtain prediction results of the second ship motion; and denormalizing the prediction results obtained by the Gaussian process regression model to obtain final ship motion prediction results.

Abstract: A liquid dispensing device mounted on a liquid container comprises a lower-plunger, an upper-plunger, a syringe, a rotating-cap and a hollow stud-bolt, combined such that the syringe is secured at the opening of the liquid container and the rotating-cap is set at the proximal end of the syringe. The rotating-cap runs on the hollow stud-bolt to set a dispense volume. The lower-plunger and upper-plunger are facing each other inside the syringe. The lower-plunger that passes through the distal end of the syringe is pushed into the syringe and when the lower-plunger is pulled back, a precise volume of liquid is trapped between the lower-plunger and the upper-plunger inside the syringe and dissipated from a dispensing outlet on the barrel of the syringe.

Abstract: A novel apparatus for mounting tissue sections to microscope slides and method of use are provided. Current methods of mounting tissue sections on microscope slides can be challenging for researchers, often result in torn, twisted, or creased tissue sections and are low throughput. The described novel tissue mounting apparatus provides an improved, efficient and easy-to-use tool for researchers in mounting tissue sections on microscope slides while maintaining the integrity of the tissue. The tissue mounting apparatus comprises a fluid-filled open-top chamber containing a stage specifically designed for seating a microscope slide(s) at the center on the floor of the chamber. The stage characteristically is leveled and elevated from the floor. The tissue sections can settle on a microscope slide that is submerged in the liquid inside the mounting chamber. After the tissue sections adhere to the microscope slide in the fluid filled chamber, the fluid can be removed.

Abstract: A liquid dispensing device provides precise and adjustable control for dosing volumes. The device is adaptable when installed on bottles and tubes and works independently if equipped with its own container. A micrometer sitting on the outside cylinder of the device adjusts the position of a syringe to change the dispensing volume. The distal end of the cylinder holds the syringe. Inside the syringe, there are the upper and lower plungers. After adjusting the position of the syringe, the extended arm of the lower plunger is pushed all the way into the device so that the lower plunger emerges out of the open end of the syringe. This allows the liquid to flow into a pocket space partitioned by the upper plunger which is passively pushed to the position by the extended arm of lower plunger. After the liquid is filled, the extended arm of the lower plunger is pulled back towards the distal end. As the lower plunger retracts, a precise volume of liquid is trapped between upper and lower plungers in the syringe.

Abstract: The invention provides methods for quickly and efficiently detecting receptor-ligand binding, including high throughput, cell-based assay methods. Assay methods for detecting mediators of receptor-ligand binding and for screening cDNA libraries are also provided.

Abstract: Use of recombinant viral vector for gene therapy is hampered by the native virus-host interaction. Non-specific gene transfection causes adverse effects in gene therapy. To solve this problem, a fusion protein ligand capable of modifying viral tropism has been created. The fusion protein comprises a viral cellular receptor at one end and an antibody Fc-binding protein at the other end. By the design, the fusion protein ligand when coupled with an antibody can block the native viral infection and redirect the virus to specific cellular surface marker as long as the antibody binds to this marker. Using adenovirus and adenoviral receptor as an example, the fusion protein ligand when coupled with anti ICAM-1 IgG redirects virus to cultured human endothelial cells expressing ICAM-1. Infection by viruses depends on the presence of viral receptor on the host cells and this requirement limits the use of viral vector for gene therapy.
