Abstract: One or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. A wireless station may be configured to perform a method to accelerate discovery of a peer device after an out-of-band triggering event. For example, a wireless device may detect an out-of-band triggering event and activate a wireless interface capable of peer-to-peer communications in response. The wireless device may transmit one or more discovery messages (e.g., discovery beacons, active subscribe messages, and/or unsolicited publish messages) over the wireless interface immediately after activation of the wireless interface to aid in discovery of the peer device. The one or more discovery messages may be transmitted as service discovery frames. The wireless device may perform service discovery over the wireless interface with the peer device post discovery.

Abstract: Disclosed are data processing and analysis methods for gene expression data for identifying endogenous reference genes and a composition for the quantitative analysis of gene expression, comprising a pair of primers and/or probes useful in amplifying the identified endogenous reference genes. Introduced with the concepts of “Zero's proportion” and CV, the method allows different datasets to be integrally analyzed, thereby searching for novel reference genes. By the method, 2,087 genes are first found as housekeeping genes which are expressed in most tissues, and the usefulness thereof in the relative quantification of different target genes is determined by analyzing their expression stability. Of the 2,087 genes, 13 genes show higher expression stability with lower expression levels across a wide range of samples than traditional reference genes such as GAPDH and ACTS, and therefore are suitable for the normalization of universal genes having relatively low expression levels.

Abstract: A time-domain segmented calibration method for a characteristic impedance of a time-domain reflectometer is provided. The method first segments the measured characteristic impedance value according to the reflection coefficients ?, determines several boundary points with the reflection coefficients, and divides the range of the measured impedance according to the impedance values corresponding to the reflection coefficients of the boundary points, and then select a typical impedance value in the range as a reference impedance for calibration. The TDR instrument performs characteristic impedance calibration for each typical reference impedance value one by one, and stores them as calibration parameters of different groups. With respect to different impedance value ranges, the selection ranges of the calibration and measurement areas of TDR are different. When the measurement is performed, the 50? calibration parameter is used as the default reference for calculation.

Abstract: In some aspects, the disclosure is directed to methods and systems for providing coordinative security among network devices across multi-level networks. Shared cryptographic secrets among the network devices are used as the basis for mutual security authentication and peering among these devices. The cryptographic secrets can be embedded in the SoC devices for these devices or dynamically generated based on unique identification information and attributes of these SoC devices. The messages for authentication and peering can be communicated directly among the network devices or indirectly via a cloud security portal entity that acts as a messaging proxy. The mutual authentication and peering process can be carried out coordinately among the network devices and a cloud security portal in a one-to-one mesh relationship, or in a transitive layering relationship, where each network entity authenticates and peers with its direct subordinates in a multi-level network.
