A Modular Data Acquisition System using the 10 GSa/s PSEC4 Waveform Recording Chip

Posted by Chicago

Kavli Affiliate: Eric Oberla | First 5 Authors: M. Bogdan, E. Oberla, H. J. Frisch, M. Wetstein, | Summary: We describe a modular multi-channel data acquisition system based on the 5-15 Gigasample-per-second waveform-recording PSEC4 chip. The system architecture incorporates two levels of hardware with FPGA-embedded system control and in-line data processing. The front-end unit is […]

Evidence for simultaneous jets and disk winds in luminous low-mass X-ray binaries

Posted by klaurent MIT

Kavli Affiliate: Norbert Schulz | First 5 Authors: Jeroen Homan, Joseph Neilsen, Jessamyn L. Allen, Deepto Chakrabarty, Rob Fender | Summary: Recent work on jets and disk winds in low-mass X-ray binaries (LMXBs) suggests that they are to a large extent mutually exclusive, with jets observed in spectrally hard states and disk winds observed in […]

Stability and Occurrence Rate Constraints on the Planetary Sculpting Hypothesis for “Transitional” Disks

Posted by Peking

Kavli Affiliate: Ruobing Dong | First 5 Authors: Ruobing Dong, Rebekah Dawson, , , | Summary: Transitional disks, protoplanetary disks with deep and wide central gaps, may be the result of planetary sculpting. By comparing numerical planet-opening-gap models with observed gaps, we find systems of 3-6 giant planets are needed in order to open gaps […]

Markov Chains and Unambiguous Automata

Posted by klaurent Cornell

Kavli Affiliate: David Muller | First 5 Authors: Christel Baier, Stefan Kiefer, Joachim Klein, David Müller, James Worrell | Summary: Unambiguous automata are nondeterministic automata in which every word has at most one accepting run. In this paper we give a polynomial-time algorithm for model checking discrete-time Markov chains against omega-regular specifications represented as unambiguous […]
