Active spatial control of terahertz graphene plasmons by tailoring carrier density profile. (arXiv:1911.08672v1 [cond-mat.mtrl-sci])

Graphene offers a possibility for actively controlling plasmon confinement and propagation by tailoring its spatial conductivity pattern. However, implementation of this concept has been hampered because uncontrollable plasmon reflection is easily induced by inhomogeneous dielectric environment. In this work, we demonstrate full electrical control of plasmon reflection/transmission at electronic boundaries induced by a zinc-oxide-based dual…

Approximate Bayesian inference of seismic velocity and pore pressure uncertainty with basin modeling, rock physics and imaging constraints. (arXiv:1911.08690v1 [physics.geo-ph])

We present a methodology for quantifying seismic velocity and pore pressure uncertainty that incorporates information regarding the geological history of a basin, rock physics, well log, drilling and seismic data. In particular, our approach relies on linking velocity models to the basin modeling outputs of porosity, mineral volume fractions and pore pressure through rock physics…

Photon statistics of quantum light on scattering from rotating ground glass. (arXiv:1911.08694v1 [quant-ph])

When a laser beam passes through a rotating ground glass (RGG), the scattered light exhibits thermal statistics. This is extensively used in speckle imaging. This scattering process has not been addressed in photon picture and is especially relevant if non-classical light is scattered by the RGG. We develop the photon picture for the scattering process…

The weight distribution of irreducible cyclic codes associated with decomposable generalized Paley graphs. (arXiv:1911.08549v1 [math.CO])

We use known characterizations of generalized Paley graphs which are cartesian decomposable to explicitly compute the spectra of the corresponding associated irreducible cyclic codes. As applications, we give reduction formulas for the number of rational points in Artin-Schreier curves defined over extension fields and to the computation of Gaussian periods.

Berberian extension and its S-spectra in a quaternionic Hilbert space. (arXiv:1911.08561v1 [math.FA])

For a bounded right linear operators $A$, in a right quaternionic Hilbert space $V_{\mathbb{H}}^{R}$, following the complex formalism, we study the Berberian extension $A^\circ$, which is an extension of $A$ in a right quaternionic Hilbert space obtained from $V_{\mathbb{H}}^{R}$. In the complex setting, the important feature of the Berberian extension is that it converts approximate…

Dual Reconstruction with Densely Connected Residual Network for Single Image Super-Resolution. (arXiv:1911.08711v1 [eess.IV])

Deep learning-based single image super-resolution enables very fast and high-visual-quality reconstruction. Recently, an enhanced super-resolution based on generative adversarial network (ESRGAN) has achieved excellent performance in terms of both qualitative and quantitative quality of the reconstructed high-resolution image. In this paper, we propose to add one more shortcut between two dense-blocks, as well as add…
