摘要： A computer-based learning system uses knowledge points organized with a predefined multilevel arrangement. Each knowledge point has an information set which may include a knowledge content, an evaluation content and a solution content. For a given knowledge point, the learning system provides the knowledge content and evaluation content, analyzes the user's answers to the evaluation content and determines the next knowledge point to be studied by the user based on the user's answers and the predefined multilevel arrangement of the knowledge points. The learning system thus provides a different learning course for different users to achieve individualized learning. User's learning history may be recorded to facilitate reviews by the user and improve the selection of the next knowledge point. Users may provide feedbacks on knowledge contents and evaluation contents, and may even suggest their own knowledge contents and evaluation contents to improve the learning system and user participation.

摘要： A memory device including a non-volatile re-programmable memory cell is provided. In connection with various example embodiments, the memory cell is a single resistor located between a first and second node. The resistor stores different resistance states corresponding to different resistance values set by SiCr-facilitated migration. The SiCr-facilitated migration occurs in response to energy presented between the first and second nodes. The application of a signal to a first node of the memory cell resistor forces the migration of elements along the memory cell resistor to set the resistance value of the memory cell resistor. The application of a second signal of approximately equal strength to the second node reverses the change and resistance and returns the memory cell to the previous resistance level. In some implementations the resistor is made of SiCr.

摘要： This invention relates to similar compound of glucagon-like peptide 1 (glucagon-like peptide-1, GLP-1) secreted by insulinotropic hormone, i.e. shortened glucagon-like peptide 1 (sGLP-1) consisting of 26 aminoacids. Its sequence is as follows: His-X1-Glu-Gly-Thr-Phe-Thr-Ser-Asp-Val-Ser-Ser-Tyr-Leu-Glu-Gly-Gln-Ala-Ala-Lys-Glu-Phe-Ile-Ala-Trp-Leu (SEQ ID NO: 2). In comparison with the present GLP-1 and its similar compound, the shortened glucagon-like peptide 1 (sGLP-1) in this invention has the following prominent advantages: 1. After reconstruction, the shortened peptide chain has stronger simulation to islet cell captors and stronger insulin secretion stimulation action; 2. the reconstructed simulation sequence can resist dipeptidyl peptidase decomposition by change of the second aminoacid sequence from Ala to Gly or Ser to prolong its half time and enhance drug action; 3. To shorten the peptide chain leads to reduced synthesis cost.

摘要： The present invention relates to a tracking method and a tracking device adopting multiple observation models with different life spans. The tracking method is suitable for tracking an object in a low frame rate video or with abrupt motion, and uses three observation models with different life spans to track and detect a specific subject in frame images of a video sequence. An observation model I performs online learning with one frame image prior to the current image, an observation model II performs online learning with five frames prior to the current image, and an observation model III is offline trained. The three observation models are combined by a cascade particle filter so that the specific subject in the low frame rate video or the object with abrupt motion can be tracked quickly and accurately.

摘要： Provided are semiconductor die flip chip packages and semiconductor die flip chip package components where certain properties of the packages/components are controlled to facilitate management of the package stresses. Also provided are fabrication methods for such packages and package components. For instance, the thickness of a die can be controlled such that the stress generated/experienced by the die is minimized. As such, the package stress is managed to suitable levels for incorporation of a low-K Si die and/or a thin package substrate. Further, a thin die can be attached to a heat spreader to increase the rigidity for easier handling during fabrication of the semiconductor die flip chip package.

摘要： Provided are semiconductor die flip chip packages with warpage control and fabrication methods for such packages. A package includes a heat spreader that is attached to a die and a stiffener, which are in turn attached to a package substrate. In general, the stiffener is made of a material that has a relatively low CTE value. For example, the stiffener material may have a CTE value less than 12 ppm/° C. The material may also have a relatively low mass density value of less than 8.9 g/cm3. Such a material may include natural graphite or some composite form of it. The result is a package with less bowing and so improved co-planarity (e.g., in compliance with industry specifications) with the surface to which it is ultimately bound; thereby, improving the reliability of the package. Moreover, a package that is relatively lighter and more robust than conventional semiconductor die flip chip packages can be realized.
