A generalized stability theory (GST) analysis of baroclinic shear flow is performed using primitive equations (PEs), and typical synoptic-scale midlatitudinal values of vertical shear and stratification. GST is a comprehensive linear stability theory that subsumes modal stability theory and extends it to account for nonmodal interactions such as may occur among the approximately geostrophically...

Size-selected Mon , Wn , and Fen cluster anions are deposited on a weakly interacting substrate (highly oriented pyrolytic graphite) and studied ex-situ using atomic force microscopy. Depending on size, three growth modes can be distinguished. Very small clusters consisting of less than 10–30 atoms behave similar to atoms and coalesce into 3-dimensional bulk-like islands. Medium sized clusters ...

Growth manipulation methods, which have been successfully used to improve the growth of homoepitaxial films, are applied to molecular beam epitaxy of the heteroepitaxial system Ni/Cu~111!. The procedures applied are temperature reduction during nucleation and pulsed ion bombardment during deposition. While the first does not lead to smoother films, the ion beam assisted growth is successful in ...

Throughout life, adult organs continually adapt to variable environmental factors. Adaptive mechanisms must fundamentally differ from homeostatic maintenance, but little is known about how physiological factors elicit tissue remodeling. Here, we show that specialized stem cell responses underlie the adaptive resizing of a mature organ. In the adult Drosophila midgut, intestinal stem cells inter...

Many social researchers measure multidimensional variables, such as rural leadership, by aggregating the scores of individual dimensions / sub-dimensions. These dimensions / sub-dimensions are highly correlated and have inherent problem of multicolinearity which causes attenuation in measurement. In order to overcome this problem, the M-K-J-B-D method developed by a group of researchers, has be...

We report in situ observations of the growth of endotaxial CoSi(2) nanowires on Si(110) using an ultrahigh vacuum transmission electron microscope with a miniature electron-beam deposition system located above the pole-piece of the objective lens. Metal deposition at 750-850 °C results in formation of coherently strained silicide nanowires with a fixed length/width (L/W) aspect ratio that depen...

Media spaces were designed to support informal as well as formal communication among remote users. We believe that these systems must be integrated into existing environments in a lightweight way, blending support for collaboration with the user's existing computer environment. This demonstration presents videoSpace, a software toolkit that facilitates the integration of live video into documen...

The automatic generation of volumes bounding the intersection of two implicit surfaces (isosurfaces of real functions of 3D point coordinates) or feature based volumes (FBV) is presented. Such FBVs are defined by constructive operations, function normalization and offsetting. By applying various offset operations to the intersection of two surfaces, we can obtain variations in the shape of an F...
