A target user directing method and apparatus and provided. The method includes determining a similarity between each of candidate users and a seed user by using a similarity model. A conversion prediction model is used to predict a probability that each of the candidate users performs a conversion operation on to-be-delivered information. One or more target users for the to-be-delivered information are selected from the candidate users according to the similarity that is determined and the probability that is predicted for each of the candidate users. The to-be-delivered information is transmitted to the one or more target users.

Target user directing method and apparatus and computer storage medium

An intravascular stent () comprises a framework with openings and at least one radiopaque structure (). Each radiopaque structure () comprises fixed bodies and radiopaque markers () filled in the fixed bodies. The fixed bodies are connected with the framework, and are at least partially disposed in the openings. The envelope enclosed area of all the radiopaque markers () in each radiopaque structure () is less than or equal to 2 mm, and a sum of effective areas of all the radiopaque markers () in each radiopaque structure () is greater than or equal to 0.15 mm, and a ratio of said sum of effective areas to said envelope enclosed area is greater than or equal to 1:5. The radiopaque structure () has a desirable visibility, and does not substantially affect the crimped diameter of the intravascular stent ().

Intravascular stent

A Zr-based composite ceramic material, a preparation method thereof and a shell or a decoration are provided. The Zr-based composite ceramic material includes a zirconia matrix and a cubic SrNbOstable phase dispersed within the zirconia matrix, where 0.7&#x2264;x&#x2264;0.95.

Zr-based composite ceramic material, preparation method thereof, and shell or decoration

A method and a system for processing network media information are provided. The method includes: collecting historical distribution effect data of network media information; performing attribute improvement processing on the historical distribution effect data by using population attribute data and network media information management data to obtain characteristic attribute data; constructing an effect parameter estimation model corresponding to each attribute of the characteristic attribute data, and training the effect parameter estimation model; estimating an effect parameter value of each audience for target network media information according to the effect parameter estimation model; and selecting an audience whose estimated effect parameter value is greater than or equal to a specified threshold value to form an audience population package to be extracted. The present invention can improve efficiency of extraction, reduce labor cost, and improve precision of distribution of network media information in an audience population package.

Method and system for processing network media information

A method for allocating an information display amount includes: determining an estimated display amount of unallocated information according to a total original display amount of all information display units and a displayed amount of allocated information; acquiring a predetermined display amount of the unallocated information according to the estimated display amount of the unallocated information; and allocating information displayed by each information display unit and a display amount according to the predetermined display amount of the unallocated information and a remaining display amount of the allocated information.

Method and apparatus for allocating information display amount

A ceramic and a preparation method therefor are provided. The ceramic includes a zirconia matrix, and an additive dispersed inside and on an outer surface of the zirconia matrix. The additive is an oxide including elements A and B, where A is selected from at least one of Ca, Sr, Ba, Y, and La, and B is selected from at least one of Cr, Mn, Fe, Co, and Ni.

Ceramic and preparation method therefor

A ceramic and a method for preparing a ceramic are provided. The ceramic includes an alumina and an oxygen-containing compound of strontium having a perovskite structure.

Ceramic and method for preparing the same

The present invention provides a method and device for pushing information. The method comprises: obtaining a designated query input on a web page; matching the designated query with queries in a query candidate set including queries having a tendency of carrying an image; and when a query in the query candidate set matches the designated query, outputting a corresponding image on the web page according to the designated query.

Method and device for pushing information

The present application provides method of searching information. The method comprises: performing a searching request based on a searching request including one or more query words from a user terminal and initially ranking all the searched items; evaluating the position click ratio of each ranking position with respect to the query words; calculating a compensation factor of respective ranking position by dividing the evaluated position clicks ratio of each ranking position by the evaluated position clicks ratio of the first ranking positions; obtaining a ranking score of each initially ranked item by dividing the item clicks ratio of each initially ranked item by the compensation factor corresponding to the ranking positions of the initially ranked item; and re-ranking all the initially ranked items in descending order based on the ranking scores and then returning the re-ranked items to the user terminal.
