The evolution of a vertically propagating three-dimensional vortex pair in ambient stratification is studied with a three-dimensional numerical model. We consider a range of Reynolds (Re) and Froude (Fr) numbers, and initialize the vortex pair in a c

We discuss the results of direct numerical simulations of three-dimensional (3D) anti-parallel vortex pairs evolving in ambient stratification for a range of Reynolds ( Re ) and Froude ( Fr ) numbers. These results have relevance to both the study of

The evolution of a vertically propagating vortex pair in stratified and sheared environments is studied with a two-dimensional numerical model. We consider a range of Froude (Fr) and Richardson (Ri) numbers, and a limited number of Reynolds numbers (

We present an analysis of the wind and temperature measurements made by rocket, radar, and satellite instrumentation in the equatorial and subtropical middle atmosphere accompanying the MALTED/CADRE campaign conducted at Alcantara, Brazil during Augu

A growth mode and interface structure analysis has been performed for Ag deposited at a high temperature of 300°C on the HF-treated Si(111):H surface by means of medium-energy ion scattering and elastic recoil detection analysis of hydrogen. The mea

In a previous study the authors used a nonlinear, compressible, spectral collocation numerical model to examine the evolution of a breaking gravity wave in two and three dimensions. The present paper extends that effort to examine the implications of

Since this is the tenth Chemical and Biological Sensing Conference, it is timely to reflect on progress in this field. We present a perspective on biological standoff detection from the point of view of past and current programs at the Johns Hopkins

We have found that polymer light-emitting diodes (LEDs) contain high concentrations of metal impurities prior to operation. Narrow peaks in the electroluminescence spectrum unambiguously demonstrate the presence of atomic indium and aluminum. Rutherf

Long-term measurements of the global distribution of clouds and the surface reflectance are needed to provide inputs to climatological models for global change studies. The Geostationary Imaging Fabry-Perot Spectrometer (GIFS) instrument is a next-ge

We report light emission from light emitting diodes with poly(3‐octylthiophene) (P3OT) as the active layer in both forward and reverse bias operation. The onset of electroluminescence (EL) of ITO/P3OT/Al devices occurs at current densities of 6.25
