Taking advantage of the high NMR detection sensitivity and the large chemical shift dispersion offered by ultra-high field strength of 7 T, the effect of magnetization transfer on inorganic phosphate (Pi) resonance during saturation of gamma-ATP resonance, mediated by the ATP synthesis reaction, was observed noninvasively in the human primary visual cortex by using in vivo 31P magnetic resonanc...

STIS/CCD data were acquired in a time series mode on α Cen A & B to test limitations to ultra high Signal to Noise (S/N) capabilities. In order to reach a Poisson limited noise level of nearly 40,000 on α Cen A the data were acquired in a spectral mode to spread the image over a full row of pixels, and with an exposure time that led to strong over-saturation. Each 10s exposure resulted in detec...

The constitutive relationships required for the parameterization of multiphase flow and transport problems are of critical importance to hydrologic modeling. Recently, a hypothesis has been developed that predicts a functional relationship between capillary pressure, saturation, and interfacial area. A network model was developed to test this hypothesis. Microscale physical processes were simul...

The ringing phenomenon in whispering-gallery-mode (WGM) microcavities has demonstrated its great potential for highly-sensitive and high-speed sensing. However, traditional symmetric WGM microcavities have suffered from an extremely low coupling efficiency via free-space coupling because the emission of symmetric WGMs is non-directional. Here we report a new approach for high-speed ultra-sensit...

Transient enhanced diffusion �TED� results from implantation damage creating enhanced diffusion of dopants in silicon. This phenomenon has mostly been studied using boron marker layers. We have performed an experiment using boron, phosphorus, and dislocation markers to compare TED effects. This experiment shows that phosphorus is enhanced significantly more than boron during damage annealing. D...

The fading phenomenon resulting from standing waves is a factor in quality deterioration in mobile communication technologies (e.g., cellular phones and television receivers). Suppression of this fading phenomenon is needed for many kinds of technologies. A single-feed planar antenna composed of two antenna components, a Planar Monopole Antenna (PMA) and a Planar Slot Antenna (PSA), is proposed...

The relationship between elastic wave velocities and water saturation in a water/gas reservoir depends strongly on whether saturation is heterogeneous (patchy) or homogeneous. Heterogeneity in saturation may result from lithologic heterogeneity because under conditions of capillary equilibrium, different lithologies within a reservoir can have different saturations, depending on their porositie...

A rotation rate and X-ray luminosity analysis is presented for rapidly rotating single and binary M-dwarf systems. X-ray luminosities for the majority of both single & binary M-dwarf systems with periods below ≃ 5−6 days (equatorial velocities, Veq∼>6 km s) are consistent with the current rotation-activity paradigm, and appear to saturate at about 10 of the stellar bolometric luminosity. The si...

Electromagnetically Induced Transparency (EIT) refers to the phenomenon of rendering an otherwise opaque medium, transparent to a narrow band of light frequencies. Physics underlying this phenomenon and its use as atomic frequency standard has been discussed extensively in literature. An ultra-narrow linewidth of the EIT signal may be considered as a narrow band frequency filter, since it is as...
