20 p, 358.1 KB Normal sequences with given limits of multiple ergodic averages / Liao, Lingmin (Université Paris-Est Creteil) ; Rams, Michal (Polish Academy of Sciences (Varsóvia, Polonia).Institute of Mathematics.)
We are interested in the set of normal sequences in the space {0, 1} N with a given frequency of the pattern 11 in the positions k, 2k. The topological entropy of such sets is determined.

11 p, 788.5 KB Redundancy and optimization of tANS entropy encoders / Blanes Garcia, Ian (Universitat Autònoma de Barcelona. Departament d'Enginyeria de la Informació i de les Comunicacions) ; Hernández-Cabronero, Miguel (Universitat Autònoma de Barcelona. Departament d'Enginyeria de la Informació i de les Comunicacions) ; Serra Sagristà, Joan (Universitat Autònoma de Barcelona. Departament d'Enginyeria de la Informació i de les Comunicacions) ; Marcellin, Michael W. (University of Arizona. Department of Electrical and Computer Engineering)
Nowadays entropy encoders are part of almost all data compression methods, with the Asymmetrical Numeral Systems (ANS) family of entropy encoders having recently risen in popularity. Entropy encoders based on the tabled variant of ANS are known to provide varying performances depending on their internal design. [...]

19 p, 1.0 MB Characterizing Normal and Pathological Gait through Permutation Entropy / Zanin, Massimiliano (Department of Computer Science, Faculty of Science and Technology, Universidade Nova de Lisboa, 2829-516 Lisboa, Portugal) ; Gómez-Andrés, David (Hospital Universitari Vall d'Hebron.

Departamento de Anatomía, Histología y Neurociencia) ; Universitat Autònoma de Barcelona
Cerebral palsy is a physical impairment stemming from a brain lesion at perinatal time, most of the time resulting in gait abnormalities: the first cause of severe disability in childhood. Gait study, and instrumental gait analysis in particular, has been receiving increasing attention in the last few years, for being the complex result of the interactions between different brain motor areas and thus a proxy in the understanding of the underlying neural dynamics.

15 p, 865.3 KB Iris recognition algorithm based on Contourlet Transform and Entropy / Ezzaki, Ayoub (Mohammed V University in Rabat. Physics Department) ; Idrissi, Nadia (Mohammed V University in Rabat. Physics Department) ; Moreno Dueñas, Francisco Ángel (Universidad de Málaga. Departamento de Ingeniería de Sistemas y Automática) ; Masmoudi, Lhoussaine (Mohammed V University in Rabat. Physics Department)
The iris is one of the most secure biometric information that is widely employed in authentication systems. In this paper we present a method for iris recognition based on the Contourlet Transform and Entropy which entails i) the detection and segmentation of the iris, ii) its normalization, iii) the application of the Contourlet Transform, iv) the generation of the iris descriptor, and v) the matching between the query iris and those in the database. [...]

28 p, 460.9 KB Invariant fibrations for some birational maps of ℂ2 / Cimà, Anna (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Zafar, Sundus (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
In this article, we extract and study the zero entropy subfamilies of a certain family of birational maps of the plane. We find these zero entropy mappings and give the invariant fibrations associated to them.

12 p, 400.7 KB Thermodynamics of organic cation exchange selectivity in smectites / Teppen, Brian J. (Michigan State University. Department of Crop and Soil Sciences) ; Aggarwal, Vaneet (Michigan State University. Department of Crop and Soil Sciences)
The selectivities of clay minerals for larger organic cations over smaller ones have been attributed-to favorable clay-organic interactions in clay interlayers and to hydrophobic effects resulting from (partial) dehydration of organic cations in the clay interlayers, but the magnitudes of these energy components have not been estimated. [...]

30 p, 2.8 MB Enhancing Confusion Entropy (CEN) for binary and multiclass classification / Delgado de la Torre, Rosario (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Nuñez Gonzalez, Jose David (Universidad del País Vasco. Departamento de Matemáticas)
Different performance measures are used to assess the behaviour, and to carry out the comparison, of classifiers in Machine Learning. Many measures have been defined on the literature, and among them, a measure inspired by Shannon's entropy named the Confusion Entropy (CEN). [...]

30 p, 321.0 KB Who Is Bowling Alone? Quantile Treatment Effects of Unemployment on Social Participation / Kunze, Lars (Technische Universität Dortmund) ; Suppa, Nicolai (Centre d'Estudis Demogràfics)
This article examines heterogeneity in the effect of unemployment on social participation. Whereas existing studies on this relationship essentially estimate mean effects, we use quantile regression methods to provide a broader and more complete picture. [...]

26 p, 414.4 KB Dynamical classification of a family of birational maps of C2 via algebraic entropy / Zafar, Sundus (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Cimà, Anna (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
This work dynamically classifies a 9-parametric family of birational maps f: C→ C. From the sequence of the degrees d of the iterates of f, we find the dynamical degree δ(f) of f. We identify when d grows periodically, linearly, quadratically or exponentially. [...]
