    摘要： A method and system are disclosed for improving the performance of a multiline transmission system by using one or more split-pair receivers in a multiline communications system to identify crosstalk on a pair of transceivers coupled to the split pair receivers, wherein each split pair receiver receives a signal including the crosstalk from each transceiver and provides a corresponding signal vector to a post processing unit, and performing MIMO post-processing on signal vectors received at a receiver from each transceiver and each split-pair receiver while minimizing crosstalk on pairs of lines in the multiline communications system with a frequency equalizer.

    摘要： A method and apparatus to establish a trustworthy local time based on trusted computing methods are described. The concepts are scaling because they may be graded by the frequency and accuracy with which a reliable external time source is available for correction and/or reset, and how trustworthy this external source is in a commercial scenario. The techniques also take into account that the number of different paths and number of hops between the device and the trusted external time source may vary. A local clock related value which is protected by a TPM securely bound to an external clock. A system of Accuracy Statements (AS) is added to introduce time references to the audit data provided by other maybe cheaper sources than the time source providing the initial time.

    摘要： A method and apparatus for performing Joint Randomness Not Shared by Others (JRNSO) is disclosed. In one embodiment, JRNSO is determined in Frequency Division Duplex (FDD) using a baseband signal loop back and private pilots. In another embodiment, JRNSO is determined in Time Division Duplex (TDD) using a baseband signal loop back and combinations of private pilots, private gain functions and Kalman filtering directional processing. In one example, the FDD and TDD JRSNO embodiments are performed in Single-Input-Single-Output (SISO) and Single-Input-Multiple-Output (SIMO) communications. In other examples, the FDD and TDD embodiments are performed in Multiple-Input-Multiple-Output (MIMO) and Multiple-Input-Single-Output (MISO) communications. JRNSO is determined by reducing MIMO and MISO communications to SISO or SIMO communications. JRNSO is also determined using determinants of MIMO channel products. Channel restrictions are removed by exploiting symmetric properties of matrix products.

    摘要： Three different reaction steps were combined to provide methods for preparing p-hydroxystyrene and p-hydroxycinnamic acid monomers from tyrosine. The three steps include reductive alkylation of tyrosine, followed by oxidation to the N-oxide, and thermal Cope elimination. During Cope elimination, either p-hydroxycinnamic acid or p-hydroxystyrene was produced depending on the absence or presence of base, respectively. Additionally, p-acetoxystyrene may be prepared by reacting the prepared p-hydroxystyrene either directly or after isolation with an acetylating agent.
