Spans of Preference Functions for De Bruijn Sequences
Abbas Alhakim
A nonbinary Ford sequence is a de Bruijn sequence generated by simple rules that determine the priorities of what symbols are to be tried first, given an initial word of size w…
Holographic c-theorems and higher derivative gravity
James T. Liu, Wafic Sabra, Zhichen Zhao
In AdS/CFT, the holographic Weyl anomaly computation relates the a-anomaly coefficient to the properties of the bulk action at the UV fixed point. This universal behavior suggests…
Towards Cosmological Black Rings
J. B. Gutowski, W. A. Sabra
We classify all pseudo-supersymmetric near horizon geometries of extremal black holes in five dimensional de-Sitter supergravity coupled to vector multiplets. We find that there ar…
Cosmological Einstein-Maxwell Instantons and Euclidean Supersymmetry: Beyond Self-Duality
M. Dunajski, J. B. Gutowski, W. A. Sabra +1
We construct new supersymmetric solutions to the Euclidean Einstein-Maxwell theory with a non-vanishing cosmological constant, and for which the Maxwell field strength is neither s…
Massive Gravity: Exorcising the Ghost
Lasma Alberte, Ali H. Chamseddine, Viatcheslav Mukhanov
We consider Higgs massive gravity [1,2] and investigate whether a nonlinear ghost in this theory can be avoided. We show that although the theory considered in [10,11] is ghost fre…
Resource Allocation via Sum-Rate Maximization in the Uplink of Multi-Cell OFDMA Networks
Hina Tabassum, Zaher Dawy, Mohamed Slim Alouini
In this paper, we consider maximizing the sum-rate in the uplink of a multi-cell OFDMA network. The problem has a non-convex combinatorial structure and is known to be NP hard. Due…
