Presented is a system and method for determining a user's intent. Specifically, constituents and a topology are derived from the user's expression of intent, which can be stated broadly or stated in specific detail. The intent is expressed verbally, written, or in an XML format. The constituents and topology are resolved into a configuration based upon contexts. The contexts, which include a resource context, a user context, and an application context, includes information about the user's preferences, location, restrictions, device and network availability, and content availability. The configuration is then implemented.

The invention relates to an AFP recombinant protein, and an in vitro high-efficiency recombination expression method, and specifically relates to a recombinant protein of artificial signal peptide-AFP-609aa-6his, and an in vitro high-efficiency recombination expression method of mammal transient expression system. DNA sequence of the AFP recombinant protein is represented by SEQ ID No.1. The in vitro high-efficiency recombination expression method comprises following steps: a, DNA sequence of the AFP recombinant protein is optimized; b, gene of the AFP recombinant protein is cloned into pcDNA3.1+ carrier via double enzyme digestion, pcDNA3.1+-AFP expression plasmid is constructed, and plasmid extraction is performed; c, transfection of pcDNA3.1+-AFP plasmid, which is obtained via extraction, into CHO-S suspension cells is realized using PEI, and recombinant protein expression is preformed; and d, 7 days later, the AFP recombinant protein is obtained via separation and purification. Activity of the AFP recombinant protein is close to that of natural AFP protein, wherein the artificially synthesized AFP recombinant protein with 6HIS labels is prepared via large-scaled transient suspension CHO-S expression system; purity is relatively high; endotoxin content is low; no pollution is caused by animal-based protein; and it is possible for the AFP recombinant protein to be used as a tumor antigen vaccine in liver cancer immunotherapy.

A method and a system are provided for encoding and processing digital information. The digital information is encoded according to binary encoding formats corresponding to primitive data types. The primitive data types comprise scalar data types including Boolean, integer, float, decimal, time stamp, string, symbol, binary large object, and character large object data types. The primitive data types also comprise composite data types including structure, list, and S-expression data types. The binary-encoded digital information is stored in a message with a predetermined format for transmission. No metadata is included in the message.

One of a plurality of prepared given expressions is displayed on a screen. After the given expression is presented to the user, the position of a face feature point is detected from a face image of the user taken by a camera cartridge. Based on the detected position of the face feature point, the user's expression in the face image is expressed in accordance with the evaluation criteria corresponding to the given expression, and an image representing the evaluation result is displayed on the screen. Thus, the user can effectively train the mimetic muscles.

In systems which support oral entry of Personal Identification Number (PIN) values in order to establish access to user accounts, a user is prompted to enter the PIN value for a particular account. The entered PIN value is analyzed by a speech recognition engine to extract both a multi-digit number and the user's expression of that number. The extracted multi-digit number is compared to a multi-digit number stored in a user record associated with the account. If the user previously specified that expression matching is required, the extracted expression of the multi-digit number is compared to a preferred expression stored in the user record. Matches must be found for both the numbers and the form in which those numbers are expressed in order for the user to be authenticated. The user may elect to dispense with the expression matching requirement.

The invention discloses a maneuvering target tracking method under constraint conditions, comprising the steps of: A, obtaining the position measurement information of a maneuvering target; B, converting the position measurement information into Cartesian coordinate measurement; C, establishing a constrained coordinate static model in a one-dimensional space, i.e., building the mileage S expression of the position of the maneuvering target in road x, y directions; D, setting motion models according to motion characteristics of the maneuvering target, and establishing a state equation and a measurement equation according to the established expression; and E, for each motion model, filtering converted Cartesian coordinate measurement to obtain a one-dimensional variable mileage S and speed filtering result. According to the embodiment, the tracking performance of a maneuvering target can be improved.
