A High-Speed Fully Digital Phase-Synchronizer Implemented in a Field Programmable Gate Array Device
Metrology and Measurement Systems, 2017 Most systems used in quantum physics experiments require the efficient and simultaneous recording different multi-photon coincidence detection events. In such experiments, the single-photon gated counting systems can be applicable.

Wide-bandwidth, tunable, multiple-pulse-width optical delays using slow light in cesium vapor [PDF]
, 2007 We demonstrate an all-optical delay line in hot cesium vapor that tunably delays 275 ps input pulses up to 6.8 ns and 740 input ps pulses up to 59 ns (group index of approximately 200) with little pulse distortion.

Time-delayed beam splitting with energy separation of x-ray channels
, 2013 We introduce a time-delayed beam splitting method based on the energy separation of x-ray photon beams. It is implemented and theoretically substantiated on an example of an x-ray optical scheme similar to that of the classical Michelson interferometer ...

When Queueing Meets Coding: Optimal-Latency Data Retrieving Scheme in Storage Clouds [PDF]
, 2014 In this paper, we study the problem of reducing the delay of downloading data from cloud storage systems by leveraging multiple parallel threads, assuming that the data has been encoded and stored in the clouds using fixed rate forward error correction ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Osteosarcoma is a radioresistant tumor that may benefit from stereotactic body radiation therapy (SBRT) for locoregional control in metastatic/recurrent disease. We report institutional practice patterns, outcomes, toxicity, and failures in osteosarcoma patients treated with SBRT.
