We compare heavy quark tagging and anti-tagging efficiencies for vertex detectors with different inner raddi using the topological vertex technique developed at the SLC/SLD experiment. Charm tagging benefits by going to very small inner radii. Talk presented at 5th International Linear Collider Workshop (LCWS 2000) Fermilab, Batavia, Illinois 24-28 Oct 2000 ∗Work supported by Department of Ener...

A novel technique using an acousto-optic frequency shifter in optical frequency domain imaging (OFDI) is presented. The frequency shift eliminates the ambiguity between positive and negative differential delays, effectively doubling the interferometric ranging depth while avoiding image cross-talk. A signal processing algorithm is demonstrated to accommodate nonlinearity in the tuning slope of ...

We present compact crossings for silicon-on-insulator photonic wires. The waveguides are broadened using a 3 microm parabolic taper in each arm. By locally applying a lower index contrast using a double-etch technique, loss of confinement is reduced and 97.5% transmission (-1.7 dB) is achieved with only -40 dB cross talk.

How primary sensory neurons contribute to persistent pain remains unclear. A novel imaging technique introduced here by Kim et al. (2016) in this issue of Neuron to view the activities of large numbers of ganglion neurons simultaneously analyzes the importance of neuronal cross-talk in pain transmission.

We describe the application of a gravity wave-generating technique to certain higher dimensional black holes. We find that the induced waves generically destroy the event horizon producing parallelly propagated curvature singularities. Based on a talk presented at the Seventh Canadian Conference on General Relativity and Relativistic Astrophysics in Calgary, AB, Canada, May 31 – June 7, 1997. E...
