In this paper, we study the plasmonic thermal conductance of ordered stacks of metallic nanorings in a host material. Using second quantized formalism of the Random Phase Approximation, we first determine the dispersion relations of surface plasmon waves on the stacks of nanorings. Then, using Landauer-Buttiker formalism, we determine the coefficient of plasmonic thermal conductance and heat cu...

The Support Vector Machine error bound is a function of the margin and radius. Standard SVM algorithms maximize the margin within a given feature space, therefore the radius is fixed and thus ignored in the optimization. We propose an extension of the standard SVM optimization in which we also account for the radius in order to produce an even tighter error bound than what we get by controlling...

We present upper and lower bounds for the number in of interval graphs on n vertices. Answering a question posed by Hanlon, we show that the ordinary generating function I(x) = ∑ n≥0 in x n for the number in of n-vertex interval graphs has radius of convergence zero. We also show that the exponential generating function J(x) = ∑ n≥0 in x n/n! has radius of convergence at least 1/2.

We describe the application of a vector-based radius approach to optical bench radius measurements in the presence of imperfect stage motions. In this approach, the radius is defined using a vector equation and homogeneous transformation matrix formulism. This is in contrast to the typical technique, where the displacement between the confocal and cat's eye null positions alone is used to deter...

We apply a spectral stacking technique to Westerbork Synthesis Radio Telescope observations measure the neutral atomic hydrogen content (HI) of nearby galaxies in and around galaxy groups at $z < 0.11$. Our sample includes 577 optically-selected (120 isolated 457 satellites) covering stellar masses between 10$^{10}$ 10$^{11.5}$ M$_{\odot}$, cross-matched with Yang's group catalogue, angular red...

background: expansion of bone marrow cavity and decreased cortical and trabecular bone tissues and osteoporosis are resulted from beta-thalassemia. the aim of this study was to assess bone mineral density (bmd) in patients with β thalassemia major and intermedia, and to determine their biochemical and hormonal profiles that may affect bmd. materials and methods: in a cross sectional study from ...

Abstract. The joint spectral radius is the extension to two or more matrices of the (ordinary) spectral radius ρ(A) = max |λi(A)| = lim‖A m‖1/m. The extension allows matrix products Πm taken in all orders, so that norms and eigenvalues are difficult to estimate. We show that the limiting process does yield a continuous function of the original matrices—this is their joint spectral radius. Then ...
