Abstract: Technologies are described herein for relevance-based expiration of data. An initial expiration time for the data is computed based upon an expiration duration associated with the data. The expiration time for the data is periodically re-computed in order to extend the expiration time. A relevance value for the meeting data is computed and the expiration time is set as a function of the computed relevance value. The relevance value may be computed as a product of a user-settable relevance value for the meeting data and a dynamic relevance point for the meeting data. When the computed expiration time for meeting data has been reached, the meeting data is expired, such as through the deletion of the meeting data.

Abstract: An equalizer is applied to a signal to be transmitted via at least one multiple input, multiple output (MIMO) channel or received via at least one MIMO channel using a matrix equalizer computational device. Channel state information (CSI) is received, and the CSI is provided to the matrix equalizer computational device when the matrix equalizer computational device is not needed for matrix equalization. One or more transmit beamsteering codewords are selected from a transmit beamsteering codebook based on output generated by the matrix equalizer computational device in response to the CSI provided to the matrix equalizer computational device.

Abstract: A method, system, and computer-readable medium for determining a number of mycobacteria in source image data of a sputum-smear sample are provided. First image data is extracted from the source image data of the sputum-smear sample. Binary image data is created from the extracted first image data. A plurality of groups of blobs is identified in the created binary image data. A distance between a pair of the identified plurality of groups of blobs is determined. If the distance is below a threshold value, the pair is combined as a single group of blobs. The determining is repeated for pairs of the identified plurality of groups of blobs, and the remaining groups of blobs are then classified.

Abstract: Methods for protecting gate stacks during fabrication of semiconductor devices and semiconductor devices fabricated from such methods are provided. Methods for fabricating a semiconductor device include providing a semiconductor substrate having an active region and a shallow trench isolation (STI) region. Epitaxial layer is formed on the active region to define a lateral overhang portion in a divot at the active region/STI region interface. A gate stack is formed having a first gate stack-forming layer overlying the semiconductor substrate. First gate stack-forming layer includes a non-conformal layer of metal gate-forming material which is directionally deposited to form a thinned break portion just below the lateral overhang portion. After the step of forming the gate stack, a first portion of the non-conformal layer is in the gate stack and a second portion is exposed. The thinned break portion at least partially isolates the first and second portions during subsequent etch chemistries.

Abstract: Techniques provided for allowing external access by other users to private information that is maintained on local storage of a computer and owned by an information owner. The private information is uploaded from the local storage to an externally accessible information source that is accessible by the other users. A request from a user to access the private information is received by the owner, who determines whether to allow access the private information. If so, the owner sends a private information sharing authorization to a collaboration orchestrator, which retrieves the private information from the external source and provides the private information to the user. The owner optionally requests to collaborate with the user before deciding whether to allow access to the private information. One or both of the identities of the owner and user can remain anonymous until agreeing on revealing identities. A system and program product is also provided.

The techniques include partitioning one or more input datasets into multiple subcomponents, analyzing a plurality of jobs to determine which of the plurality of jobs require scanning of one or more common subcomponents of the one or more input datasets, and scheduling a plurality of jobs that require scanning of one or more common subcomponents of the one or more input datasets, facilitating a single scanning of the one or more common subcomponents to be used as input by each of the plurality of jobs.

Abstract: A method and mechanism for reducing lock time of a dual-path phase lock loop (PLL). The PLL comprises a dual-path low-pass filter (LPF). The LPF includes a first filter and a second filter. The first filter comprises a passive second-order lead-lag low-pass filter. The second filter comprises a first-order lag low-pass filter. During a lock-acquisition state, an impedance value within the second stage is bypassed, which increases the loop bandwidth of the PLL. In addition, a resistance within the first stage is increased in order to increase the gain of the first stage and maintain stability within the PLL. During a lock state, the impedance value may no longer be bypassed and the increased resistance may be returned to its original value.

Abstract: In a technique for managing keyword bid amounts in an online advertising system (OAS), a closed-loop feedback technique that integrates data integration, keyword management, bid management, product-search results and user activities is used to optimize revenue generation from online advertisements for websites, such as e-commerce websites. In particular, bids on a group of keywords associated with products are based on an estimated profitability of the group of keywords. Then, the resulting traffic to an associated e-commerce website is monitored by determining a financial performance metric of the e-commerce website, which facilitates subsequent feed-back adaptation. For example, a layout of the e-commerce website (such as product information, which is associated with the products, and/or relative positions of the displayed product information on the e-commerce website) is adjusted based on the determined financial performance metric.

Abstract: Clock-domain-crossing systems and methods include an integrator that accumulates input samples over multiple clock cycles in a first clock domain to generate an accumulation result. Clock-domain-crossing circuitry samples the accumulation result in the first clock domain after each of a repeating accumulation count to generate a first domain accumulation. The first domain accumulation is sampled in a second clock domain after a time delay to generate a second domain accumulation. The time delay ensures proper setup and hold time parameters for the second clock domain relative to the first clock domain. A differentiator generates output information in the second clock domain by delaying the second domain accumulation and subtracting the delayed second domain accumulation from the second domain accumulation. The systems and methods preserve temporal characteristics of the input information in the first clock domain when it is transferred to the second clock domain as the output information.

Abstract: A wireless communication system and method uses a spatial spreading matrix to distribute the encoded spatial data streams to a number of transmit chains and further uses the spatial spreading matrix for antenna selection computation in a transmitter. The spatial spreading matrix is designed such that a receiver is able to know and utilize the spatial spreading matrix for computing transmission antenna selection, receiver antenna selection and joint transmission/receiving antenna selection. The use of this spatial spreading matrix for antenna selection computation provides increased accuracy in antenna selection for transmission of spatial data streams, where the number of spatial data streams is less than the number of transmit or receive chains between the transmitter and receiver, and the number of transmit or receive chains is less than the corresponding transmission or receiving antennas.

Abstract: A base station (e.g., a Node B in a Multi-Point HSDPA network) calculates an amount of data to request from a network node (e.g., a radio network controller or RNC). As a part of the algorithm utilized, a length of a queue at the Node B for buffering the flow may be dynamically adjusted in an effort to optimize the trade-off between buffer underrun and skew. Further, a network node (e.g., the RNC) responds to Node B flow control requests. Here, the RNC may determine the amount of data to send to the Node B in response to the flow control message from the Node B, and may send the data to the Node B. In various aspects of the present disclosure involving a Multi-Point HSDPA system, the flow control algorithm at the RNC coordinates packet flow to the primary serving cell and the secondary serving cell for the UE.
