Abstract:
A protocol for operation of wireless devices enables a wireless device to remotely and securely invoke a service on a target wireless device without requiring the user of the target wireless device to take any action and without requiring the target wireless device to use power unnecessarily. Mutual authentication is executed while the target wireless device remains in a low power discoverable mode. The discoverable mode includes discovery windows separated by inactive windows when the radio of the target wireless device is powered down.
Abstract:
Particular aspects provide methods and compositions (e.g., gene marker panels) having substantial utility for at least one of diagnosis, identification and classification of colorectal cancer (CRC) (e.g., tumors) relating to distinctive DNA methylation-based subgroups of CRC including CpG island methylator phenotype (CIMP) groups (e.g., CIMP-H and CIMP-L) and non-CIMP groups. Exemplary marker panels include: B3GAT2, FOXL2, KCNK13, RAB31 and SLIT1 (CIMP marker panel); and FAM78A, FSTL1, KCNC1, MYOCD, and SLC6A4 (CIMP-H marker panel). Further aspects relate to genetic mutations, and other epigenetic markers relating to said CRC subgroups that can be used in combination with the gene marker panels for at least one of diagnosis, identification and classification of colorectal cancer (CRC) (e.g., tumors) relating to distinctive CIMP and non-CIMP groups.
Abstract:
A microelectromechanical system (MEMS) diaphragm is provided. The MEMS diaphragm includes a first conductive layer, a second conductive layer and a first dielectric layer. The first conductive layer is disposed on a substrate and having a plurality of openings. The openings having a first dimension and the openings having a second dimension are arranged alternately, and the first dimension is not equal to the second dimension. The second conductive layer is disposed between the first conductive layer and the substrate. The first dielectric layer is partially disposed between the first conductive layer and the second conductive layer, so that a portion of the first conductive layer is suspended.
Abstract:
An access point that implements operating modes in which beacons may be selectively disabled. Beacons may be disabled when no device is actively associated through the access point. Beacons may be enabled in response to one or more triggers, which may include events such as a client forming an association through the access point following a probe request message identifying the access point. In addition, active beaconing may be triggered by user input or may occur during periodic brief intervals that allow client devices to discover the network identifier for the access point. Selective control of beaconing may lead to more effective wireless communication, particularly in areas where users congregate with computers implementing soft APs for personal networks.
Abstract:
A communication system in which an access point and one or more devices communicating through the access point adaptively apply Orthogonal Frequency Division Multiple Access (OFDMA). The access point may assign orthogonal subcarriers to devices as in conventional OFDMA, but the access point senses activity on the subcarriers and selects subcarriers without activity for assignment. In an alternative approach, a device that is configured for OFDMA communication may receive a channel assignment from a device that does not support OFDMA. The OFDMA-capable device may use only a portion of the subcarriers in the assigned channel, which may be communicated to the non-OFDMA device. During the non-OFDMA device may then ignore unused subcarriers in error detection and correction to avoid incorrectly classifying communications as erroneous. Information about OFDMA capabilities, subcarrier assignments and subcarriers in use may be communicated as information elements in network control communications, such as beacons and probe messages.
Abstract:
The invention provides methods for modifying lignin content and composition in plants and achieving associated benefits therefrom involving altered expression of newly discovered MYB4 transcription factors. Nucleic acid constructs for modifying MYB4 transcription factor expression are described. By over-expressing the identified MYB4 transcription factors, for example, an accompanying decrease in lignin content may be achieved. Plants are provided by the invention comprising such modifications, as are methods for their preparation and use.
Abstract:
Embodiments of the present invention provide a method for feeding back channel state information, and a method and a device for obtaining channel state information. The method for feeding back the channel state information includes: compressing, by a user equipment, original time domain channel state information to obtain compressed time domain Channel state information: quantizing the compressed time domain channel state information to obtain a codebook index; and sending the codebook index to a base station. With the technical solutions provided by the embodiments of the present invention, the total overhead used for feeding back the channel state information from the user equipment to the base station is reduced.
Abstract:
A priority hash index provides efficient lookup of posting lists for search query terms. The priority hash index is a data structure in which hash values for terms are distributed across multiple storage devices based on importance of the terms and access speeds of the storage devices. Terms are grouped into search lists with each search list including a storage location on each storage device. When a search query is received, a term is identified and hashed to a location on the first storage device and to generate a unique hash value for the term. The locations on the storage device for the term's search list are sequentially read until the hash value for the term is located to access the posting list for the term.
Abstract:
A method for zooming image shown in a touch screen includes reading information of a continuous writing locus formed on the touch screen; selecting a first group of points and a second group of points in the writing locus formed in time sequence; dealing with the first group and second group of points and obtaining a first radius and a second radius; comparing the first radius and the second radius to define a zooming command; executing the zooming command. A touch screen reading such writing locus into zooming command is also provided.

An LED includes a substrate, a first n-type GaN layer, a connecting layer, a second n-type GaN layer, a light emitting layer, and a p-type GaN layer. The first n-type GaN layer is formed on the substrate, the first n-type GaN layer has a first surface facing away from the substrate, and the first surface includes a first area and a second area. The connecting layer, the second n-type GaN layer, the light emitting layer, and the p-type GaN layer are formed on the first area in sequence. The connecting layer is etchable by alkaline solution; a bottom surface of the second n-type GaN layer facing towards the connecting layer has a roughened exposed portion; the GaN on the bottom surface of the second n-type GaN layer is N-face GaN.
