System application techniques using time synchronization

Abstract: A method and apparatus for accurately distributing traceable time values to a set of nodes in a system. Each node includes a slave clock that synchronizes a slave time value using a synchronization protocol. The system includes a traceable time source that generates a traceable time value and a master node having a master clock that synchronizes a master time value to the traceable time value and that distributes the master time value to the slave clocks via the communication link. The nodes may be distributed nodes or cards connected to a backplane.

Lipidomic “Deep Profiling” : An Enhanced Workflow to Reveal New Molecular Species of Signaling Lipids

Abstract: Current mass spectrometry-based lipidomics aims to comprehensively cover wide ranges of lipid classes. We introduce a strategy to capture phospho-monoester lipids and improve the detection of long-chain base phosphates (LCB-Ps, e.g., sphingosine-1-phosphate). Ten novel LCB-Ps (d18:2, t20:1, odd carbon forms) were discovered and characterized in tissues from human and mouse, as well in D. melanogaster and S. cerevisiae. These findings have immediate relevance for our understanding of sphingosine-1-phosphate biosynthesis, signaling, and degradation.

Performance Monitoring and Measurement Techniques for Coherent Optical Systems

Abstract: Modern spectrally efficient optical communication systems utilize polarization-multiplexed coherent transmission in complex modulation format. Coherent receivers used in these systems measure the amplitude and phase of the optical signals for both orthogonally polarized components carrying information. Knowledge of the amplitude and phase of the optical field, in combination with digital signal processing, gives the receiver an inherent metrology and performance monitoring capability. As the optical signal propagates from the transmitter over optical fiber to the receiver, a signal transformation and degradation is expected. The receiver observes the properties of the transmitted optical signal as degraded by the impairments of the transmission medium. The details of monitoring optical signal parameters and link impairments are the focus of this paper. The optical signal parameters include polarization state and residual carrier phase; optical link impairments include chromatic dispersion and polarization mode dispersion. Two distinct techniques are presented: one based on Stokes space analysis, and the other on Kalman filtering. The Stokes space techniques are modulation-format independent and do not require demodulation. The Kalman filtering provides optimal estimation of the physical quantities that describe the optical signal and the optical medium.

Purified thermostable Pyrococcus furiosus DNA polymerase I

Abstract: Purified thermostable Pyrococcus furiosus DNA polymerase that migrates on a non-denaturing polyacrylamide gel faster than phosphorylase B and Taq polymerase and more slowly than bovine serum albumin and has an estimated molecular weight of 90,000-93,000 daltons when compared with a Taq polymerase standard assigned a molecular weight of 94,000 daltons.
