The invention belongs to the field of genetic engineering and in particular relates to novel endoglucanase, coding genes cel5A-h31 and application thereof. A nucleotide sequence of genes cel5A-h31 coding the endoglucanase is shown as SEQ ID No. 1. Bioinformatics analysis shows that the endoglucanase coded by the genes belongs to the fifth family. The endoglucanase is successfully cloned by the inventor by virtue of a design primer and successfully expressed in a prokaryotic expression system, the recombinant endoglucanase obtained by induced ultrasonic purification has an optimal operating pHvalue of 5.0 and an optimal temperature of 55 DEG C, can maintain relatively stable enzymatic activity at a temperature of 50 DEG C or below, has high pH tolerance and can maintain the enzymatic activity of 75% or higher at the pH value of 5.0-9.0. The recombinant endoglucanase has high research and industrial application potential.

The invention discloses an intelligent jewelry recommendation system, which includes an intelligent terminal device, and the connecting end of the intelligent terminal device is provided with a product library unit, a database unit, a data acquisition unit, a feature extraction unit, an analysis and comparison unit, an audio-visual unit and a data input unit; the intelligent terminal device is a terminal carrier for terminal data processing and system operation in the system, wherein the intelligent terminal device is internally provided with an independent microprocessor, specifically an ARM64-bit processor, for completing instruction fetching and execution , and exchange information with the product library unit, database unit and audio-visual unit connected externally to the intelligent terminal, and provide performance support for data processing and computing. The invention enables customers to select more suitable products when purchasing products, and improves the shopping experience of customers and the sales performance of merchants.

The invention relates to the field of genetic engineering and in particular relates to endoglucanase as well as an encoding gene cel5A-h42 and application thereof. The gene cel5A-h42 for encoding theendoglucanase has a nucleotide sequence shown as SEQ ID No. 1. Bioinformatic analysis shows that the endoglucanase encoded by the gene belongs to the fifth family of glycoside hydrolase. The inventorsuccessfully clones the encoding gene through a designed primer and the encoding gene is successfully expressed in a prokaryotic expression system; the recombinant endoglucanase obtained by inducing ultrasonic purification has the optimum effect pH (Potential of Hydrogen) of 5.0 and the optimum temperature of 55 DEG C, and can keep relatively stable enzyme activity at 50 DEG C. The enzyme has relatively strong pH tolerance when the pH is 5.0 to 10.0 and 70 percent or more of the enzyme activity can be kept. The recombinant endoglucanase has a relatively great research and industrial application potential.

The invention discloses a timely and high-efficiency crawling method for internet information and belongs to the technical field of information. The method comprises the following steps: (1) setting a seed address, crawling and storing webpage information, and ensuring navigation pages; (2) carrying out more than once crawling on each navigation page, and analyzing and labeling the crawling webpage; (4) building a theme judgment model and a navigation page change time series prediction model of each website; (5) predicting next time change time of each website navigation page, ensuring next crawling time, crawling the navigation page and extracting a subpage address and an anchor text which are not crawled; (6) adopting the built theme judgment model to judge the extracted subpage address and the anchor text in the last step, and respectively processing the extracted subpage address and the anchor text according to a judgment result; (7) based on a new related page of the crawled theme, forming or updating a present change time series of each website navigation page, and ensuring next crawling time to carry out webpage crawling. The timely and high-efficiency crawling method for the internet information guarantees novelty and topicality of collected information under a small load.

The invention discloses a method for unblocking a touch screen device and the touch screen device. Due to the fact that predetermined unblocking tracks, an icon, a main interface window and a user operating authorization are related, a user can acquire different icons, different main interface windows and different grades of user operating authorizations after unblocking the touch screen device by adopting different unblocking tracks. Therefore, the novelty of application interfaces of the touch screen device is guaranteed, and security and confidentiality of the touch screen device are increased. Meanwhile, the user can define the predetermined unblocking tracks, the icon and the main interface window by himself, accordingly, the user can set the unblocking tracks and the application interfaces according to his own situation, the demand for personalization of the user is fully met, and the user can operate the touch screen device conveniently.

To overcome the defect in prior art, the related method considers fully the relation between sentences and the relation between sentence and user query to generate the abstract both with main file information and topic explanation or query answer, and applies difference penalty algorithm to ensure the novelty of abstract. This invention can meet individual request.
