Abstract: A polyolefin-based film is described. Through optimization of tortuosity of a pore structure in the polyolefin-based film, the polyolefin-based film has a uniform pore structure, thereby improving consistency of the base film, reducing performance deviation of the base film, and effectively ensuring air permeability of the base film. Additionally, the polyolefin-based film of this application is ultra-thin. For every 1 ?m reduction in thickness, energy density of a battery cell can increase by approximately 0.7%. Therefore, with the thickness controlled to be below 7 ?m, the energy density of the battery cell is improved. When the polyolefin-based film is used as a separator in a battery, electrical performance of the battery can be improved, including reducing battery internal resistance, direct current resistance, self-discharge rate, short-circuit rate, and the like.

Abstract: This application relates to a polyolefin-based film, including polyolefins with different weight-average molecular weights; where thickness of the polyolefin-based film is ?6 ?m, and the polyolefin-based film has a machine-direction shrinkage of ?2% and a transverse-direction shrinkage of ?1% at 115° C./1 h. This application uses polyolefins with different weight-average molecular weights as raw materials, enabling the resulting polyolefin-based films to have an ultra-thin thickness and a low thermal shrinkage. The reduction in thickness of the polyethylene-based film can improve the energy density of the cell to some extent, and the reduction in thermal shrinkage can improve the short-circuit test pass rate of the bare cell, enhancing the safety performance of the cell. In addition, the reduction in thermal shrinkage helps improve the heat resistance of the polyolefin-based film, delaying the thermal failure of adjacent cells when thermal runaway occurs in a cell.

Abstract: A compression transmission method for real-time data is provided, when both a sending terminal and a receiving terminal have accumulated historical data, that is, there is business knowledge. The business knowledge is used by the receiving terminal to construct and train a self-coding network and a fully connection neural network, to thereby construct an output prediction model of an encoder. After the model converges, parameters of the model and a predicted result of an intermediate layer of the self-coding network are sent to the sending terminal by the receiving terminal with a nonreal-time method. After verifying by the sending terminal, the sending terminal decides to send the real-time data or not to send the real-time data to the receiving terminal, and the real-time data is decompressed into simulated real-time data by the receiving terminal according to the predictive result of the intermediate layer of the self-coding network.

Abstract: The invention relates to method for the efficient expression and purification and application of a recombinant fusion protein of MANNase and homologues thereof and GLP-1. Through genetic recombination technology, soluble proteins are obtained by using high density fermentation of Pichia pastoris to induce secretory expression, followed by isolation and purification by filtration and concentration to obtain high yield of target proteins. The high fermentation expression and simple isolation steps solve the limitations of the current GLP-1 analogs such as low drug yield, high cost and the need for frequent injections. More importantly, the fusion protein has hypoglycemic effect not only by injection, but also by oral administration for hypoglycemia and weight reduction, which has good application value in obese and pre-diabetic patients. It also provides a basis for further research on the mechanism of hypoglycemia and weight loss of mannanase and homologues thereof with GLP-1 recombinant fusion protein.
