From a set of thirteen cataclysmic binaries that were discovered in the Swift Burst Alert Telescope (BAT) survey, we conducted time-resolved optical spectroscopy and/or time-series photometry of eleven, with the goal of measuring their orbital periods and searching for spin periods. Seven of the objects in this study are new optical identifications. Orbital periods are found for seven targets, ...

Transforming growth factor beta (TGFbeta) signaling is transduced via Smad2-Smad4-DNA-binding protein complexes which bind to responsive elements in the promoters of target genes. However, the mechanism of how the complexes activate the target genes is unclear. Here we identify Xenopus Swift, a novel nuclear BRCT (BRCA1 C-terminal) domain protein that physically interacts with Smad2 via its BRC...

The distribution and abundance of swift foxes (Vulpes velox) has declined from historic levels. Causes for the decline include habitat loss and fragmentation, incidental poisoning, changing land use practices, trapping, and predation by other carnivores. Coyotes (Canis latrans) overlap the geographical distribution of swift foxes, compete for similar resources, and are a significant source of m...

This paper presents Swift, a packet filter for high performance packet capture on commercial off-the-shelf hardware. The key features of Swift include (1) extremely low filter update latency for dynamic packet filtering, and (2) Gbps high-speed packet processing. Based on complex instruction set computer (CISC) instruction set architecture (ISA), Swift achieves the former with an instruction se...

Since the successful launch of NASA’s dedicated gamma-ray burst (GRB) mission, Swift, the study of cosmological GRBs has entered a new era. Here I review the rapid observational and theoretical progress in this dynamical research field during the first two-year of the Swift mission, focusing on how observational breakthroughs have revolutionized our understanding of the physical origins of GRBs...

We have designed and implemented an optimizing Java compiler called Swift for the Alpha architecture. Swift translates Java bytecodes to optimized Alpha code, and uses static single assignment (SSA) form for its intermediate representation (IR). The Swift IR is relatively simple, but allows for straightforward implementation of all the standard scalar optimizations. The Swift compiler also impl...

The technical approach is to use Surface Wave Instrument Floats with Tracking (SWIFT) buoys to measure waves, winds, and turbulence at the air-sea-ice interface (Thomson, 2012). The SWIFT deployments were successfully completed during the summer of 2014. These seasonal SWIFT measurements are placed in context using mutliyear subsurface Acoustic Wave And Current (AWAC) moorings and regional WAVE...

The swift fox (Vulpes velox) is a small canid currently listed as endangered in the state of Nebraska. Current and future construction of the Heartland Expressway Corridor (HEC) through the Nebraska panhandle may be a cause for concern for resident swift fox populations. Current swift fox presence along the roadway will be documented before construction continues. We surveyed for swift foxes wi...

Introduction: Ultrashort echo-time (UTE) imaging (1) and sweep imaging with Fourier transformation (SWIFT) (2) are techniques for imaging hard tissues with short T2 relaxation times on the order of a few tens to hundreds of microseconds, due to their very short acquisition delays (in the range of 0.01-0.5 ms). Such short T2 components are not easily detected with conventional imaging techniques...
