A novel point mutation in the ND6 subunit of complex I at position 14,459 of the mitochondrial DNA (MTND6*LDY T14459A) was identified as a candidate mutation for the highly tissue-specific disease. Leber's hereditary optic neuropathy plus dystonia. Since the MTND6*LDYT14459A mutation was identified in a single family, other pedigrees with the mutation are(More)
Using a new grism at the Keck Interferometer, we obtained spectrally dispersed (R ∼ 230) interferometric measurements of the Mira star R Vir. These data show that the measured radius of the emission varies substantially from 2.0-2.4 µm. Simple models can reproduce these wavelength-dependent variations using extended molecular layers, which absorb stellar(More)
A recently developed JHU public turbulence database [1, 2] provides new ways to access large datasets generated from high-performance computer simulations of turbulent flows to perform numerical experiments. The database archives 1024 4 (spatial & time) data points obtained from a pseudo-spectral direct numerical simulation (DNS) of forced isotropic(More)
Directly detecting thermal emission from young extrasolar planets allows measurement of their atmospheric compositions and luminosities, which are influenced by their formation mechanisms. Using the Gemini Planet Imager, we discovered a planet orbiting the ~20-million-year-old star 51 Eridani at a projected separation of 13 astronomical units. Near-infrared(More)
(ULB) program has served as a company owned low cost rapid prototyping platform to examine all aspects of vertical takeoff and landing unmanned aerial system operations. Designed with an optionally manned capability, the program has conducted most developmental flight test activity in civil airspace just north of the Boeing Facility in Mesa, Arizona. In(More)
We demonstrate a method based on MPI client-server implementation for storing the output of computations directly into the database. Our method automates the previously used inefficient ingestion process which required development of special tools for each simulation. In large-scale channel flow simulation experiments we were able to ingest the output data(More)
We present spatially resolved near-IR spectroscopic observations of 15 young stars. Using a grism spectrometer behind the Keck Interferometer, we obtained an angular resolution of a few milli-arcseconds and a spectral resolution of 230, enabling probes of both gas and dust in the inner disks surrounding the target stars. We find that the angular size of the(More)
that commercial bumble bee (Bombus impatiens Cresson, Hymenoptera: Apidae) colonies can serve as potential alternative hosts for the small hive beetle (SHB, Aethina tumida Murray, Coleoptera: Nitiduli-dae), a honey bee pest (Lundie 1940; Neumann and Elzen 2004; Ellis and Hepburn 2006). Using olfacto-ry choice tests, Graham et al. (2011) found that SHB(More)
The W. M. Keck telescope was used to observe the impact of comet Shoemaker-Levy 9 (SL9) fragment R at a wavelength of 2.3 micrometers on 21 July 1994. The data showed three outbursts. The first flash lasted about 40 seconds and was followed 1 minute after its peak by a second flash that lasted about 3 minutes. A third, longer lasting flare began 6 minutes(More)
