Abstract: The present invention relates to a layered semi-parallel LDPC decoder system having a single permutation network, and belongs to the field of decoder hardware design. The system comprises a layered decoding architecture of the single permutation network, a layered semi-parallel decoding architecture of the single permutation network, a pipeline design for layered semi-parallel decoding and a hardware framework of a layered semi-parallel LDPC decoder. The present invention removes a permutation network module between a check node and a variable node by modifying the cyclic shift value of each information block transferred from the variable node to the check node, i.e., the cyclic shift operation of the decoder can be completed through the single permutation network so as to reduce hardware resources of the decoder. A semi-parallel decoding structure is adopted, and meanwhile, a pipeline is added between half layers.

Abstract: An array substrate is provided. The array substrate includes a base substrate and a plurality of gate lines, a plurality of data lines, a common electrode layer and a plurality of pixel units arranged in an array disposed on the base substrate. Each of the pixel units includes a plurality of sub-pixel units defined by gate lines and data lines disposed to intersect each other laterally and vertically. The common electrode layer includes a plurality of common electrode blocks that double as self-capacitance electrodes, each of the common electrode blocks is connected with at least one wire, and the wires are in the middle of sub-pixel units of a same column.

Abstract: A riding lawn mower includes a seat, a frame, a mowing element, a deck surrounding, and forming a mowing space for accommodating at least part of the mowing element, and a first motor for driving the mowing element to rotate. The riding lawn mower may further include a footrest provided on a front side of the seat and used to support a user's feet, wherein the footrest comprises a bottom plate and a front cover protruding relative to the bottom plate. The riding lawn mower may include an indicator device for displaying a remaining capacity of the power supply device, and the indicator device is at least partially mounted to the front cover of the footrest.

Abstract: A microfluidic biomimetic fiber for cultured meat production and a preparation method therefor and use thereof are provided. The microfluidic biomimetic fiber has a shell-core structure; and an outer shell of the microfluidic biomimetic fiber is formed by cross-linking a polymer solution with cell non-adhesion, and an inner core wrapped by the outer shell is a hydrogel solution mixed with a seed cell. The present invention respectively introduces an inner phase fluid and an outer phase fluid into inner and outer phase channels of a microfluidic device, enables the two phase fluids in the channels of the microfluidic device to form a stable laminar flow structure by adjusting the flow velocities of the inner and outer phases, and extrudes same from a device outlet to obtain the biomimetic fiber.

Abstract: A medicinal xiding vial, and a dispensing apparatus and an injection apparatus thereof, comprise a reversely pressed medicinal xiding vial, a reversely pressed dispensing apparatus and a reversely pressed injection apparatus thereof, a general medicinal xiding vial, and a general injection apparatus. The reversely pressed medicinal xiding vial comprises a vial body whose inner wall is a straight cylinder. A first piston is disposed on a position close to the vial opening of the vial body. A blind hole is disposed at the center of an outer bottom surface of the first piston. The vial opening is provided with an outer edge, and a seal cap is fixed on the out edge to prevent the first piston from falling off. In combination with the dispensing apparatus and the injection apparatus thereof, the medicinal xiding vial can solve the problem of secondary pollution during medicine dispensing and injection.

Abstract: A cutting and double-face leather integrated dyeing process for Tan sheep skin, which comprises the following steps: cutting?washing with water?retanning?primary dyeing?primary color fixing?secondary dyeing?fatliquoring?secondary color fixing?bleaching?drying?a finished product. Tan sheep skin leather boards and fleeces dyed by the process of the invention have no cross color and color fading with each other, a high color fastness, and uniform dyeing; the prepared Tan sheep skin products such as clothing, etc., not only have the characteristics of a high added value and good practicability, but also can more largely increase product benefits and lower the production cost.

Abstract: The invention relates to the technical field of animal fur processing, and particularly relates to a cutting and double-face leather integrated dyeing process for Tan sheep skin, which comprises the following steps: cutting?washing with water?retanning?primary dyeing?primary colour fixing?secondary dyeing?fatliquoring?secondary colour fixing?bleaching?drying?a finished product. In the process of the invention, the third-grade Tan sheep skin which does not reach a superior quality is selected and subjected to cutting treatment and then double-face leather integrated dyeing; after the dyeing has been completed, the leather board has softness, good fullness and elongation, substantially uniform thickness, and no phenomena such as stiff board and swelling board occur; the fleece is smooth, flexible and loose and clean with complete needle velvet, and no phenomena such as serious fur shedding, oily fur and fur twisting occur.
