In this paper, the implicitly implemented LES method and fifth order bandwidth-optimized WENO scheme are used to make comprehensive studies on the interaction of vortex rings and shock waves of the MVG controlled flow at M=2.5 and Re θ θ θ θ =5760. The kinetic information of the vortex rings is carefully studied and provided. The interaction of the streamwise vortices and vortex rings are inves...

We present high spatial resolution maps, obtained with the Plateau de Bure Interferometer, of the blue lobe of the L1157 outflow. We observed four lines at 3 mm, namely CH3OH (2K–1K), HC3N (11–10), HCN (1–0) and OCS (7–6). Moreover, the bright B1 clump has also been observed at better spatial resolution in CS (2–1), CH3OH (21– 11)A −, and SO (32–21). These high spatial resolution observations s...

The present experiment was designed to investigate some of the labile discharge characteristics of single units in the medial geniculate body (MGB) of the locally anesthetized, paralyzed cat. In particular, the following problems were addressed : To what extent do MGB cells exhibit stationary discharge rates; what are the effects of phasic arousal (produced by infrequent shock to the paw) upon ...

A highly accurate pseudospectral solver for the inviscid, supersonic flow of a calorically perfect ideal gas over arbitrary axisymmetric blunt body geometries is verified in its ability to approximate solutions to the Euler equations to within a dimensionless error tolerance of 10 in predictions of flow quantities and validated to within a dimensionless error tolerance of 10 in comparison of it...

The paper reviews various topics in shape analysis. In particular, matching configurations using regression is emphasized. Connections with general shape spaces and shape distances are discussed. Kendall’s shape space and the affine shape space are considered in particular detail. Matching two configurations and the extension to generalized matching are illustrated with applications in electrop...

Differences between image processing and other disciplines in the definition and the role of shape are explored. Diverse approaches to quantifying shape are reviewed. Attention is drawn to the need for close coupling between image acquisition and shape analysis. An example of the effect of the means of observation on dynamic shape extraction is drawn from linguistics. Current instrumentation fo...

Motions of virtual characters in movies or video games are typically generated by recording actors using motion capturing methods. Animations generated this way often need postprocessing, such as improving the periodicity of cyclic animations or generating entirely new motions by interpolation of existing ones. Furthermore, search and classification of recorded motions becomes more and more imp...

Local scale variations within the same species are common in nature. The shape matching puzzle poses fascinating questions, like how should we measure the discrepancy between a small dog with large ears and a large one with small ears? are there similar geometric structures that are common to an elephant and a giraffe? what is the morphometric similarity between a blue whale and a dolphin? Exis...

Background—We tested the hypothesis that the shape of the shock waveform affects not only the defibrillation threshold but also the amount of cardiac damage. Methods and Results—Defibrillation thresholds were determined for 11 waveforms—3 ascending-ramp waveforms, 3 descending-ramp waveforms, 3 rectilinear first-phase biphasic waveforms, a Gurvich waveform, and a truncated exponential biphasic ...

A large number of bacteria have been found to govern virulence and heat shock responses using temperature-sensing RNAs known as RNA thermometers. A prime example is the agsA thermometer known to regulate the production of the AgsA heat shock protein in Salmonella enterica using a "fourU" structural motif. Using the SHAPE-Seq RNA structure-probing method in vivo and in vitro, we found that the r...
