Information content based model for the topological properties of the gene regulatory network of Escherichia coli
Berkin Malkoc, Duygu Balcan, Ayse Erzan
Gene regulatory networks (GRN) are being studied with increasingly precise quantitative tools and can provide a testing ground for ideas regarding the emergence and evolution of co…
On Feasibility of Interference Alignment in MIMO Interference Networks
Cenk M. Yetis, Tiangao Gou, Syed A. Jafar +1
We explore the feasibility of interference alignment in signal vector space -- based only on beamforming -- for K-user MIMO interference channels. Our main contribution is to relat…
Perturbative construction of the two-dimensional O(N) non-linear sigma model with ERG
Bekir Can Lutfuoglu, Hidenori Sonoda
We use the exact renormalization group (ERG) perturbatively to construct the Wilson action for the two-dimensional O(N) non-linear sigma model. The construction amounts to regulari…
Toward the Classification of Scalar Nonpolynomial Evolution Equations:Polynomiality in Top Three Derivatives
Eti Mizrahi, Ayşe Hümeyra Bilge
We prove that arbitrary (nonpolynomial) scalar evolution equations of order , that are integrable in the sense of admitting the canonical conserved densities $\ro^{(1)}$, $…
A Noncommutative Space Approach to Confined Dirac Fermions in Graphene
Omer F. Dayi, Ahmed Jellal
A generalized algebra of noncommutative coordinates and momenta embracing non-Abelian gauge fields is proposed. Through a two-dimensional realization of this algebra for a gauge fi…
On the evolution of anomalous X-ray pulsars and soft gamma ray repeaters with fallback disks
U. Ertan, K. Y. Eksi, M. H. Erkut +1
We show that the period clustering of anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs), their X-ray luminosities, ages and statistics can be explained with fallba…
