Semidefinite Ranking on Graphs Shankar Vembu, Thomas Gärtner, and Stefan Wrobel 1 Fraunhofer IAIS, Schloß Birlinghoven, 53754 Sankt Augustin, Germany 2 Department of Computer Science III, University of Bonn, Germany {shankar.vembu, thomas.gaertner, stefan.wrobel}@iais.fraunhofer.de We consider the problem of ranking the vertices of an undirected graph given some preference relation. Without inc...

The presence of chiral fermions in the physical Hilbert space implies consistency conditions on the spectral action. These conditions are equivalent to the absence of gauge and gravitational anomalies. Suggestions for the fermionic part of the spectral action are made based on the supersymmetrisation of the bosonic part.

‎let $p$ be a prime with $pgeq 7$ and $q=2(p-1)$‎. ‎in this paper‎ ‎we prove the existence of a nontrivial product of‎ ‎filtration $s+4$ in the stable homotopy groups of spheres‎. ‎this nontrivial‎ ‎product is shown to be represented up to a nonzero scalar by‎ ‎the product element $widetilde{gamma}_{s}b_{n-1}g_{0}in‎ ‎{ext}_{mathcal{a}}^{s+4,(p^n+sp^2+sp+s)q+s-3}(mathbb{z}/p,mathbb{z}/p)$‎ ‎in ...

We report on simulations and measurements of focusing diffractive optical elements, fabricated as two-level binary optics. The diffractive optical elements are designed to separate and focus four specific wavelengths in the infrared. The simulations are based on a local linear grating model, and predict anomalies similar to Wood's anomalies known from grating diffraction theory. The anomalies a...

As cochlear implant patients achieve greater success in understanding speech it is important to examining more complex hearing tasks. One logical step is to begin exploring some of the problems associated with music perception. Because music requires relatively precise pitch information, it can present unique challenges to current speech-oriented implant designs, which are limited in the amount...

Introduction: Spectral anomalies in Nili Patera, a central caldera of the Syrtis Major shield volcano, were first observed by [1] using Thermal Emission Spectrometer (TES) data. With the advent of data from the Thermal Emission Imaging Spectrometer (THEMIS), it is now possible to explore in greater detail the nature of the volcanic materials that give rise to both spectral and spatial anomalies...
