  • Publication number: 20200084219
    Abstract: Methods and systems of classifying suspicious users are described. A processor may determine whether a domain name, of an email address of a user that requested to access a network, is valid. The processor may classify the user as a suspicious user if the domain name is invalid. If the domain name is valid, the processor may determine a likelihood that the email address is a script-generated email address. The processor may classify the user as a suspicious user if the email address is likely to be a script-generated email address. If the email address is unlikely to be a script-generated email address, the processor may identify abnormal usage behavior exhibited by the user based on a reference model. The processor may classify the user as a suspicious user if abnormal usage behavior is identified, and may reject a subsequent request from the user to access the network.

  • Patent number: 10538569
    Abstract: The present invention relates to a fusion polypeptide containing a glucagon-like peptide (GLP) and an immunoglobulin hybrid Fc, and more specifically, to a fusion polypeptide with an increased half-life and improved efficacy compared to the conventional fusion polypeptide based on the discovery of an immunoglobulin hybrid Fc suitable for GLP or analogs thereof, and a pharmaceutical composition for treating diabetes, inflammatory bowel disease, endoenteritis or diarrhea caused by anticancer chemotherapy, or short bowel syndrome, containing the fusion polypeptide. The fusion polypeptide of the present invention has an increased half-life and improved resistance to DPP-4 enzyme compared to those of GLP-1 and GLP-2, and it thus has improved drug efficacy in treating diabetes, inflammatory bowel disease, endoenteritis or diarrhea caused by anticancer chemotherapy, or short bowel syndrome, compared to those of the conventional drugs.

  • Patent number: 10442259
    Abstract: Provided is a tire with self-inflation device. The tube is inserted inside the side portion where the extension and contraction movements of the tire are mostly occurring in order to further enhance the efficiency of the air supply to the tire cavity during driving. The air compressed towards the driving direction is injected to the tire cavity, and the air from the outside is charged to the tube due to the negative pressure formed in the tube located in the opposite side of driving. The durability is enhanced by reducing the exposed portion of the regulator.

    Abstract: An approach is provided for determining a product value score. Features of a product are identified. Ranking data for each identified feature is collected. The ranking data includes popularity, stability, availability, and memory usage of each feature. Additional data for each feature are determined. The additional data includes an importance, a conversion rate, and a marketing impact of each feature. Based on the ranking data and the additional data, normalized data is generated according to characteristics of the features. Based on a data science prediction analysis which uses the identified features, weights of the features are determined. Based on initial results of the data science prediction analysis, a key product is selected from a set of products. Based on the key product and the weights, product value scores of products in the set of products are determined.

  • Publication number: 20190213511
    Abstract: A cognitive churn-analysis system of a customer-engagement management platform predicts when and why a customer is likely to reduce a current level of service of a current service offering. The system enhances results of a conventional statistical churn analysis by using cognitive methods to infer a customer's personality traits and evolving sentiment toward the service offering. By processing the results of the statistical analysis and the two cognitive analyses, the system predicts a likelihood that a customer will reduce service at a particular time by performing a churning activity. After further determining a likely reason why the customer would choose to churn, the cognitive system directs the customer-engagement management platform to educe the likelihood that the customer would make such a decision by engaging the customer with remedial actions at an optimal time.
