We address the issue of generating texts in the style of an existing author, that also satisfy structural constraints imposed by the genre of the text. We focus on song lyrics, for which structural… (More)

The canonical quantization of any hyperbolic symplectomorphism A of the 2-torus yields a periodic unitary operator on a N-dimensional Hilbert space, N = 1 h. We prove that this quantum system becomes… (More)

We present a detailed description of an algorithm tailored to detect external plagiarism in PAN-09 competition. The algorithm is divided into three steps: a first reduction of the size of the problem… (More)

The automatic detection of shared content in written documents –which includes text reuse and its unacknowledged commitment, plagiarism– has become an important problem in Information Retrieval. This… (More)

The complexity of human interactions with social and natural phenomena is mirrored in the way we describe our experiences through natural language. In order to retain and convey such a high… (More)

We consider weakly coupled analytic expanding circle maps on the lattice Z d (for d ≥ 1), with small coupling strength 2 and coupling between two sites decaying exponentially with the distance. We… (More)

In this paper we study in detail, both analytically and numerically, the dynamical properties of the triangle map, a piecewise parabolic automorphism of the twodimensional torus, for different values… (More)

Understanding human mobility from a microscopic point of view may represent a fundamental breakthrough for the development of a statistical physics for cognitive systems and it can shed light on the… (More)

In [DDL] we defined a class of non-compact polygonal billiards, the infinite step billiards: to a given sequence of non-negative numbers {pn}n∈N, such that pn ց 0, there corresponds a table P := ⋃… (More)

We propose to study the L-norm distance between classical and quantum phase space distributions, where for the latter we choose the Wigner function, as a global phase space indicator of… (More)
