A Maximum Entropy Approach to the Realizability of Spin Correlation Matrices

  • Paolo Dai Pra,
  • Michele Pavon and
  • Neeraja Sahasrabudhe

21 June 2013

Deriving the form of the optimal solution of a maximum entropy problem, we obtain an infinite family of linear inequalities characterizing the polytope of spin correlation matrices. For n ≤ 6, the facet description of such a polytope is provided thro...

In this paper, the spatiotemporal dynamics of a diffusive Leslie-Gower predator-prey model with prey refuge are investigated analytically and numerically. Mathematical theoretical works have considered the existence of global solutions, population pe...

A Method for Choosing an Initial Time Eigenstate in Classical and Quantum Systems

  • Gabino Torres-Vega and
  • Mónica Noemí Jiménez-García

17 June 2013

A subject of interest in classical and quantum mechanics is the development of the appropriate treatment of the time variable. In this paper we introduce a method of choosing the initial time eigensurface and how this method can be used to generate t...

Entropy of Shortest Distance (ESD) as Pore Detector and Pore-Shape Classifier

  • Gabor Korvin,
  • Boris Sterligov,
  • Klaudia Oleschko and
  • Sergey Cherkasov

10 June 2013

The entropy of shortest distance (ESD) between geographic elements (“elliptical intrusions”, “lineaments”, “points”) on a map, or between "vugs", "fractures" and "pores" in the macro- or microscopic images of triple porosity naturally fractured vuggy...

To deal with the complexities associated with the rapid growth in a merged concept lattice, a formal method based on an entropy-based weighted concept lattice (EWCL) is proposed as a mechanism for merging multi-source geographic ontologies (geo-onto...

Characterization of Ecological Exergy Based on Benthic Macroinvertebrates in Lotic Ecosystems

  • Mi-Jung Bae,
  • Fengqing Li,
  • Piet F.M. Verdonschot and
  • Young-Seuk Park

7 June 2013

The evaluation of ecosystem health is a fundamental process for conducting effective ecosystem management. Ecological exergy is used primarily to summarize the complex dynamics of lotic ecosystems. In this study, we characterized the functional aspec...

Quantum Contextuality with Stabilizer States

  • Mark Howard,
  • Eoin Brennan and
  • Jiri Vala

7 June 2013

The Pauli groups are ubiquitous in quantum information theory because of their usefulness in describing quantum states and operations and their readily understood symmetry properties. In addition, the most well-understood quantum error correcting cod...

Entropy Increase in Switching Systems

  • José M. Amigó,
  • Peter E. Kloeden and
  • Ángel Giménez

7 June 2013

The relation between the complexity of a time-switched dynamics and the complexity of its control sequence depends critically on the concept of a non-autonomous pullback attractor. For instance, the switched dynamics associated with scalar dissipativ...
