Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating a computer chip floorplan. One of the methods includes obtaining netlist data for a computer chip; and generating a computer chip floorplan, comprising placing a respective node at each time step in a sequence comprising a plurality of time steps, the placing comprising, for each time step: generating an input representation for the time step; processing the input representation using a node placement neural network having a plurality of network parameters, wherein the node placement neural network is configured to process the input representation in accordance with current values of the network parameters to generate a score distribution over a plurality of positions on the surface of the computer chip; and assigning the node to be placed at the time step to a position from the plurality of positions using the score distribution.

Abstract: A micro-fluidic cartridge enables analysis of biological samples of fluid form particularly by means of optical systems. The micro-fluid cartridge includes a body, at least one fluid inlet located on the body, at least one channel connected to fluid inlet from one end and allowing flow of fluid there through, at least one first chamber arranged in a fluid communication with channel on the body, at least one biological chip located inside the first chamber and structured to keep certain components inside the fluid, at least one cover connected to the body in a manner preventing leakage of liquid from channel to outer environment on the body and having light penetration on part corresponding to at least biological chip.

Abstract: A process for using reduced vat dyes in a continuous dyeing process for production of dyed yarns and fabrics of different colors. In the process, dye composition is introduced to a treatment unit for reduction to desired dye composition. The dye concentration in the treatment unit is lower than feeding dye concentration so that dye precipitation does not occur, but significantly higher than the circulating dye concentration so that the dye is reduced efficiently. Although the preferred location for the treatment unit is before the circulation line, it may be at any location before the dip-dye tank.
