Abstract:
Based on information associated with users, a social networking system recommends one or more groups for a target user to join or to create. Characteristics of the target user, characteristics of users connected to the target user, characteristics of candidate groups in the social networking system may be used to identify groups for recommendation. The social networking system may provide questions to the target user and recommend a group to the target user based on received answers to the questions. For example, the answers to the provided question identify one or more characteristics of the target user, which are used to select a group for recommendation. Additionally, the social networking system may recommend additional users for the target user to add or invite to a group based on characteristics of the target user, the additional users, and/or the group.
Abstract:
A pilot and channel estimation method for SDMA MIMO transmission downlink is provided in the present invention, and the method provides possibility for saving the orthogonal pilot resources; the pilot signals of different users in the transmitting antenna domain can occupy the same time-frequency resources, and thereby the pilot overhead of system resources can be reduced greatly; the method includes: for the MIMO transmission downlink that employs pre-coding for SDMA, taking the quantity of orthogonal pilot resources occupied by the users in the pre-coding domain as the number of data streams that can be transmitted or the number of spatial dimensions occupied first, at the transmitting end of the base station; then, performing SDMA transmission pre-coding for the orthogonal pilots in the pre-coding domain in the same way as the data signals, to obtain the pilot signals of the users in the transmitting antenna domain; wherein, the pilots of the users in the pre-coding domain can be orthogonal in the frequency domain or code domain, and the pilots of different users in the pre-coding domain can be identical or not identical to each other; the pilot signals of different users in the transmitting antenna domain can occupy the same time-frequency resources.

The present invention provides compounds of formula I and pharmaceutically acceptable salts thereof. The formula I compounds inhibit tyrosine kinase activity of JAK3, thereby making them useful for the treatment of inflammatory and autoimmune diseases.
Abstract:
A portable electronic device includes a main body and a stylus. The main body includes a shell and a reset button received in the shell. A sidewall of the shell defines a through hole. The reset button includes a pressing pole received in the through hole. The pressing pole is concave with respect to an outer surface of the shell. The stylus is operable to be inserted into the through hole to press the button.
Abstract:
An electronic device comprises an upper housing, a lower housing, and a battery. The lower housing is engaged with the upper housing. A bottom wall of the lower housing is partially recessed to form a thin battery receiving portion. The thin battery receiving portion can give way to pressure caused by a swelling and or exploding battery.
Abstract:
A multi-antenna channel estimation method based on polyphase decomposition includes: receiving frequency domain received signals transformed using discrete fourier transformation (DFT) in pilot symbols; performing phase correction on the frequency domain received signals; performing polyphase decomposition on the frequency domain received signals which are corrected using phase correction and acquiring polyphase signals; performing interpolation on the polyphase signals and acquiring the estimation values of the multi-antenna channel parameters with various linear combinations on each frequency; acquiring decorrelation array based on the pilot structure of the transmission antenna and decorrelating the estimation values of the multi-antenna channel parameters with various linear combination on each frequency using the decorrelation array and acquiring channel parameters of the pilot symbols on each frequency; acquiring channel parameters of data symbols based on the channel parameters of the pilot symbols. With the present invention, the inversion problem in multi-antenna channel estimation is avoided with lower complexity, and results of the multi-antenna channel estimation method become more accurate since the DFT and filtering are performed in the interpolation after polyphase decomposition.

Abstract:
The present invention describes a method of reducing the enzymatic digestion rates of starch granules in food, particularly rice-based food. The method is carried out by encapsulating the starch granules with a reaction compound formed by the chemical reaction of at least a crosslinkable polysaccharide that has been pre-mixed with the ingredients for food production, and at least a crosslinking agent. The invention also relates to a process of preparing food products by incorporating the method of the present invention and food products produced by the present method.
