Abstract: A DNA sequence encoding Der p1 protein having a particular base sequence is codon-optimized for the Pichia pastoris expression system, which is conducive to expressing Der p1 in Pichia pastoris. After gene optimization and adding an activating element to increase the expression of Der p1 in molecular level, it was found that Der p1 is expressed at a higher level as compared with the prior art and has biological activity similar to the natural protein.

Abstract: The present application discloses a PEGylated asparaginase and use thereof. In this application, the polyethylene glycol (PEG) is coupled to the N-terminal amino of 1 or 2 subunits of L-asparaginase, and the molecular weight of the PEG is 30-40 KDa. The PEG is preferably branched and has an aldehyde group serving as an activating group. The PEGylated asparaginase is useful in the preparation of anti-tumor drugs.

Abstract: A plurality of circuit units of a matrix processor of a communication device are used to decompose a plurality of channel matrices, corresponding to a plurality of orthogonal frequency division multiplexing (OFDM) tones, over a plurality of cycles to determine matrix equalizer coefficients. Decomposing the plurality of channel matrices includes determining respective modes of operation for respective ones of the circuit units for respective ones of the cycles. The respective modes of operation are selected from a set of modes that includes at least one of a bypass mode for propagating input signals to output signals without altering the input signals and an idle mode for saving power when a particular circuit unit is not needed during a particular cycle. The respective circuit units are individually controlled to operate in the determined respective modes during the corresponding cycles. The determined matrix coefficients are then applied to received data signals.

Abstract: The present invention relates to composite materials for tire, specifically to composite materials of tire sidewall rubber. A preparation method of the composite materials comprises the following steps of: plasticating rubber in an internal mixer, adding other component except for the sulfur powder and the accelerator to blend, lifting ram piston at 120˜125° C., discharging rubber at 150˜160° C. to obtain rubber compound, then mixing the rubber compound with the sulfur powder and the accelerator in open mill, rolling for 4˜5 times and milling for 5˜8 times to obtain product. The composite materials of the present invention not only meet the requirements of basic mechanical properties of the sidewall rubber, but also obviously improve thermo-oxidative aging resistance and ultraviolet aging resistance of the sidewall rubber, and thereby effectively prolong the service life of the tire.

Abstract: This invention comes up with a kind of Android malicious code detection method on the base of community structure analysis. During the reverse analysis process of target program, firstly, it obtains critical static feature information automatically, such as permission, function, class, system API, etc.; secondly, it uses the call relation between functions to create function call graph, and undertakes pretreatment on function call graph; make cycle division and analysis for the weighted function call graph so as to get the correction division of community structure; finally, it extract features from community structures for machine learning and get the final maliciousness determination result. This invention method is able to undertake program internal structure analysis and malicious code detection rapidly when facing a large number of Android application program samples generated by “repackaging” technology.

Abstract: This invention public a kind of malicious software clustering method expressed based on TLSH feature, which belongs to the analysis and test area of malicious software.
