We present time-distance analyses of several active regions and a region of quiet Sun observed with the Global Oscillation Network Group (GONG). Analyzing temporal correlations between the p-mode oscillation signal observed within the sunspots with the signals integrated within surrounding annuli, we connrm the recent nding of Duvall and his colleagues that travel times (+) for outward propagat...

A new nematode species was discovered during a diversity survey of plant-parasitic nematodes on turfgrass conducted in North and South Carolina in 2010 and 2011. It is described herein as Hemicaloosia graminis n. sp. and is characterized by two annuli in the lip region, one lateral line, body 610.0-805.0 μm long, stylet 65.0-74.6 μm long, vulva at 84.1% -85.8% of the body , 254-283 annuli, vulv...

Experiments on the time-periodic liquid sloshing-induced sideways motion of containers are presented. The measurements are compared with finite-depth potential theory developed from standard normal mode representations for rectangular boxes, upright cylinders, wedges and cones of 90◦ apex angles, and cylindrical annuli. It is assumed that the rectilinear horizontal motion of the containers is f...

Background—Proponents of flexible annuloplasty rings have hypothesized that such devices maintain annular dynamics. This hypothesis is based on the supposition that annular motion is relatively normal in patients undergoing mitral valve repair. We hypothesized that mitral annular dynamics are impaired in ischemic mitral regurgitation and myxomatous mitral regurgitation. Methods and Results—A Ph...

The problem of the out of plane buckling of polar orthotropic armuli under uniform internal or external pressure loading has been investigated with the assumption of axisymmetry by numerous researchers. In this paper, the buckling of polar and rectilinearly orthotropic annuli subjected to internal or external pressure loading is examined without restriction to axisymmetric buckling modes. The b...

A theoretical model is developed to describe the formation of microstructures due plasma streaming instabilities in radially convergent geometries. Microstructures form radial spokes are found experimentally laser wakefield accelerators. The eigenvalues a set coupled linear ordinary differential equations obtained and complex wavenumbers calculated give local growth rates. predictions confirmed...

We prove the existence of free boundary minimal annuli inside suitably convex subsets of three-dimensional Riemannian manifolds with nonnegative Ricci curvature − including strictly convex domains of the Euclidean space R.

By using the second main theorem of the meromorphic function on annuli, we investigate the problem on two meromorphic functions partially sharing five or more values and obtain some theorems that improve and generalize the previous results given by Cao and Yi.

Several mean value identities for harmonic and panharmonic functions are reviewed along with the corresponding inverse properties. The latter characterize balls, annuli, strips analytically via these functions.
