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:
An adaptive transmission scheme of the channel environment in the multi-antenna wireless transmission system can raise the spectrum use rate and power efficiency of the communication system. Compared with traditional single antenna input and single antenna output, the channel environment in MIMO wireless communication system is more complex. When the terminal is moving, the different types of channels between terminal and base station can be gone through and then its capacity can be changed more largely. Embodiments of the disclosure are directed to systems that transmit high speed data by way of a plurality of transmitting and/or receiving antennae, and particularly to a transmission scheme in different channel environments in a multi-antenna wireless transmission system.
Abstract:
A portable electronic device includes a audio player, a speaker, a fixing member and an engaging opening. The audio player is configured for playing audio files and videos. The speaker is detachably couple to the audio player. The fixing member is connected to one of the audio player and the speaker. The engaging opening is defined in the other of the audio player and the speaker. The engaging portion is detachably engaged in the engaging opening.
Abstract:
A bass reflex type speaker is disclosed. The bass reflex type speaker includes an enclosure, two speakers, and a bass reflex tube. The enclosure includes a main portion and two protruding portions protruding from the main portion. The main portion defines a sound cavity therein. The protruding portion defines a sound path therein communicating with the sound cavity. The two speakers are connected to the corresponding protruding portion to close the sound path. One end of the bass reflex tube is fixed in the enclosure, and the other end of the bass reflex tube extends out of the enclosure.
Abstract:
PageRank (PR) is used by web search engine Google in ranking individual web pages. However, it is known that this value is also easily manipulated by methods known as spoofing. Further, the calculation of PR will require iterative cycles of computations to achieve a “steady” value. This would mean that huge computation resources are required to obtain reasonably reliable PR values for various web pages. This invention provides relatively accurate and simple methods for ranking the importance of a node in a network. The web graph or the network is first represented by an incidence matrix or a representation matrix W. The matrix W is then self-multiplied to obtain flow matrix. The flow capacity, or the rank of each node, is then obtained from the flow matrix.
Abstract:
The present application describes novel barbituric acid derivatives of formula I: or pharmaceutically acceptable salt or prodrug forms thereof, wherein A, B, L, R1, R2, R3, R4, R5, n, W, U, X, Y, Z, Ua, Xa, Ya, and Za are defined in the present specification, which are useful as TNF-α converting enzyme (TACE) and matrix metalloproteinases (MMP) inhibitors.
Abstract:
A ternary content addressable memory (TCAM) cell circuit formed in a TCAM memory cell array having cells arranged in rows and columns can include a first storage circuit with first and second data path, a second storage circuit with a third and fourth data path, and a compare circuit. No more than four conductive lines in a column wise direction have a direct electrical connection to the TCAM cell. Such conductive lines can include a first bit line coupled to the first data path and the third data path and a second bit line coupled to the second data path and the fourth data path.

Abstract:
A small computer system interface (SCSI) driver circuit having a programmable slew rate comprises N cascaded delay cells each including a data bit input, a delayed data bit output that communicates with the data bit input of an adjacent one of the N cascaded delay cells, and a delay time input that receives a programmable delay time value for setting a variable delay between receiving data at the data bit input and generating the delayed data bit output. N predrivers receive an output enable signal and a corresponding one of the N delayed data bit outputs and generate a predriver output signal based on the output enable and the corresponding one of the N delayed data bit outputs. N drivers have inputs that receive predriver output signals from corresponding ones of the N predrivers. An output port communicates with outputs of the N drivers.
