Geometry of Quantum Group invariant systems
Marcelo R. Ubriaco
Starting with the partition functions for quantum group invariant systems we calculate the metric in the two-dimensional space defined by the parameters and and the cor…
A Generalization of Lee Codes
Carlos Araujo, Italo J. Dejter, Peter Horak
Motivated by a problem in computer architecture we introduce a notion of the perfect distance-dominating set, PDDS, in a graph. PDDSs constitute a generalization of perfect Lee cod…
On the shape of the mass-function of dense clumps in the Hi-GAL fields. I. SED determination and global properties of the mass-functions
L. Olmi, D. Angles-Alcazar, D. Elia +11
Stars form in dense, dusty clumps of molecular clouds, but little is known about their origin and evolution. In particular, the relationship between the mass distribution of these…
Faster spectral sparsification and numerical algorithms for SDD matrices
Ioannis Koutis, Alex Levin, Richard Peng
We study algorithms for spectral graph sparsification. The input is a graph with vertices and edges, and the output is a sparse graph that approximates …
Constrained multilinear detection for faster functional motif discovery
Ioannis Koutis
The GRAPH MOTIF problem asks whether a given multiset of colors appears on a connected subgraph of a vertex-colored graph. The fastest known parameterized algorithm for this proble…
Scalar curvature of systems with fractal distribution functions
Marcelo R. Ubriaco
Starting with the relative entropy for two close statistical states we define the metric and calculate the scalar curvature for systems with classical, boson and fermion fracta…
Discovery of 6.035GHz Hydroxyl Maser Flares in IRAS18566+0408
A. A. Al-Marzouk, E. D. Araya, P. Hofner +3
We report the discovery of 6.035GHz hydroxyl (OH) maser flares toward the massive star forming region IRAS18566+0408 (G37.55+0.20), which is the only region known to show periodic…
A spectral line survey of the starless and proto-stellar cores detected by BLAST toward the Vela-D molecular cloud
Jorge L. Morales Ortiz, Luca Olmi, Michael Burton +6
We present a 3-mm and 1.3-cm spectral line survey conducted with the Mopra 22-m and Parkes 64-m radio telescopes of a sample of 40 cold dust cores, previously observed with BLAST,…
Worst-case efficient dominating sets in digraphs
Italo J. Dejter
Let . {\it Worst-case efficient dominating sets in digraphs} are conceived so that their presence in certain strong digraphs corresponds to that of effici…
