On the enumeration of permutominoes
(2013)
Although the exact counting and enumeration of polyominoes remain challenging open problems, several positive results were achieved for special classes of polyominoes. We give an algorithm for direct enumeration of ...

Phase diagram of the two-fluid Lipkin model: A "butterfly" catastrophe
(American Physical Society, 2016-03-31)
Background: In the past few decades quantum phase transitions have been of great interest in nuclear physics. In this context, two-fluid algebraic models are ideal systems to study how the concept of quantum phase transition ...

Solving common influence region queries with the GPU
(2013)
In this paper we propose and solve common influence region queries. We present GPU parallel algorithms, designed under CUDA architecture, for approximately solving the studied queries. We also provide and discuss experimental ...

On the barrier-resilience of arrangements of ray-sensors
(2013)
Given an arrangement A of n sensors and two points s and t in the plane, the barrier resilience of A with respect to s and t is the minimum number of sensors whose removal permits a path from s to t such that the path ...

Canonical Discontinuous Planar Piecewise Linear Systems
(Society of Industrial and Applied Mathematics, 2012)
The family of Filippov systems constituted by planar discontinuous piecewise linear systems with two half-plane linearity zones is considered. Under generic conditions that amount to the boundedness of the sliding set, ...

Observation of a tricritical wedge filling transition in the 3D Ising model
(Institute of Physics Publishing, 2014)
In this letter we present evidences of the occurrence of a tricritical filling transition for an Ising model in a linear wedge. We perform Monte Carlo simulations in a double wedge where antisymmetric fields act at the ...

On a seminal paper by Karlin and Mcgregor
(2013)
The use of spectral methods to study birth-and-death processes was pioneered by S. Karlin and J. McGregor. Their expression for the transition probabilities was made explicit by them in a few cases. Here we complete their ...

The class cover problem with boxes
(Elsevier, 2012)
In this paper we study the following problem: Given sets R and B of r red and b blue points respectively in the plane, find a minimum-cardinality set H of axis-aligned rectangles (boxes) so that every point in B is covered ...
