Parasitic High Q-Factor Open-Box Modes With 3-D Printed Dielectric-Filled Metal Waveguides
IEEE Access, 2021 High Q-factor open-box mode resonances have been found in the microwave measurements of several 3-D printed dielectric-filled metal-pipe rectangular waveguides (MPRWGs).

The Metric of Yang-Mills Orbit Space on the Lattice
, 2014 We find coordinates, the metric tensor, the inverse metric tensor and the Laplace-Beltrami operator for the orbit space of Hamiltonian SU(2) gauge theory on a finite, rectangular lattice. This is done using a complete axial gauge fixing.

Fusion products, Kostka polynomials, and fermionic characters of su(r+1)_k [PDF]
, 2005 Using a form factor approach, we define and compute the character of the fusion product of rectangular representations of \hat{su}(r+1). This character decomposes into a sum of characters of irreducible representations, but with q-dependent coefficients.

Spectral methods in gravity inversion: the geopotential field and its derivatives
Annals of Geophysics, 1997 The 3D spectral analysis of the gravitational potential field for a given mass distribution is studied. The derived quantities, the gravitational force field and the gravity gradient tensor are computed in frequency space.

A mixed elastoplastic / rigid plastic material model [PDF]
, 1999 A new integration algorithm for plastic deformation is derived in combination with the\ud anisotropic Hill’49 yield criterion. The algorithm degenerates to the Euler forward elastoplastic material\ud model for small deformations and to the rigid plastic ...

Simplicial cohomology of band semigroup algebras [PDF]
, 2011 We establish simplicial triviality of the convolution algebra $\ell^1(S)$, where $S$ is a band semigroup. This generalizes results of the first author [Glasgow Math. J. 2005, Houston J. Math. 2010].

A novel recursive sub-tensor hyperspectral compressive sensing of plant leaves based on multiple arbitrary-shape regions of interest [PDF]
PeerJ Computer SciencePlant hyperspectral images (HSIs) contain valuable information for agricultural disaster prediction, biomass estimation, and other applications. However, they also include a lot of irrelevant background information, which wastes storage resources.

Convective plan-form two-scale dynamos in a plane layer
, 2004 We study generation of magnetic fields, involving large spatial scales, by convective plan-forms in a horizontal layer. Magnetic modes and their growth rates are expanded in power series in the scale ratio, and the magnetic eddy diffusivity (MED) tensor ...

Improved Rectangular Matrix Multiplication using Powers of the Coppersmith-Winograd Tensor [PDF]
, 2018 In the past few years, successive improvements of the asymptotic complexity of square matrix multiplication have been obtained by developing novel methods to analyze the powers of the Coppersmith-Winograd tensor, a basic construction introduced thirty years ago. In this paper we show how to generalize this approach to make progress on the complexity of
