2 p, 83.0 KB Editorial : Porcine respiratory disease complex: dynamics of polymicrobial infections, synergistic effects and management strategies / Ramos Terrades, Natalia (Universidad de la República. Instituto de Biología) ; Sibila, Marina (Unitat mixta d'investigació IRTA-UAB en Sanitat Animal. Centre de Recerca en Sanitat Animal) ; Neira, Victor (Universidad de Chile. Departamento de Medicina Preventiva Animal)
Porcine respiratory disease complex (PRDC) is a major cause of production losses in the global swine industry. The disease is often multifactorial and polymicrobial, resulting from infection with different combinations of pathogens (including viruses, bacteria, and parasites), in addition to non-infectious factors such as environmental conditions, animal age, population size, management strategies and genetics.

28 p, 2.1 MB Dynamics of Newton-like root finding methods / Campos, Beatriz (Universitat Jaume I. Instituto de Matemáticas y Aplicaciones de Castellón) ; Canela Sánchez, Jordi (Universitat Jaume I. Institut Universitari de Matemátiques i Aplicacions de Castelló) ; Vindel, Pura (Universitat Jaume I. Instituto de Matemáticas y Aplicaciones de Castellón)
When exploring the literature, it can be observed that the operator obtained when applying Newton-like root finding algorithms to the quadratic polynomials z − c has the same form regardless of which algorithm has been used. [...]

21 p, 1.6 MB Dynamics of a family of rational operators of arbitrary degree / Campos, Beatriz (Universitat Jaume I. Instituto de Matemáticas y Aplicaciones de Castellón) ; Canela Sánchez, Jordi (Centre de Recerca Matemàtica) ; Garijo, Antoni (Universitat Rovira i Virgili. Departament d'Enginyeria Informàtica i Matemàtiques) ; Vindel, Pura (Universitat Jaume I. Instituto de Matemáticas y Aplicaciones de Castellón)
In this paper we analyse the dynamics of a family of rational operators coming from a fourth-order family of root-finding algorithms. We first show that it may be convenient to redefine the parameters to prevent redundancies and un-boundedness of problematic parameters. [...]

8 p, 1014.8 KB Phase portraits of the complex Abel polynomial differential systems / Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Valls, Clàudia 1973- (Universidade de Lisboa. Instituto Superior Técnico. Departamento de Matemàtica)
In this paper we characterize the phase portraits of the complex Abel polynomial differential equations z˙=(z−a)(z−b)(z−c),with z∈C, a,b,c∈C. We give the complete description of their topological phase portraits in the Poincaré disc, i. [...]

8 p, 458.3 KB Emergence of intra-particle entanglement and time-varying violation of Bell's inequality in Dirac matter / De Moraes Araújo, Bruna Gabrielly (Universitat Autònoma de Barcelona. Departament de Física) ; Cummings, Aron (Institut Català de Nanociència i Nanotecnologia) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia)
We demonstrate the emergence and dynamics of intraparticle entanglement in massless Dirac fermions. This entanglement, generated by spin-orbit coupling, arises between the spin and sublattice pseudospin of electrons in graphene. [...]

27 p, 6.8 MB Connectivity of the Julia set for the Chebyshev-Halley family on degree n polynomials / Campos, Beatriz (Universitat Jaume I. Institut Universitari de Matemàtiques i Aplicacions de Castelló) ; Canela Sánchez, Jordi (Université Paris-Est Marne-la-Vallée (France)) ; Vindel, Pura (Universitat Jaume I. Institut Universitari de Matemàtiques i Aplicacions de Castelló)
We study the Chebyshev-Halley family of root finding algorithms from the point of view of holomorphic dynamics. Numerical experiments show that the speed of convergence to the roots may be slower when the basins of attraction are not simply connected. [...]

We study the escaping set of functions in the class B∗, that is, transcendental self-maps of ℂ∗ for which the set of singular values is contained in a compact annulus of ℂ∗ that separates zero from infinity. [...]

We introduce a generalization of the McMullen family f_(z) = z^n /zd^. In 1988 C. McMullen showed that the Julia set of f_ is a Cantor set of circles if and only if 1/n 1/d < 1 and the simple critical values of f_ belong to the trap door. [...]

25 p, 932.3 KB Singular perturbations in the quadratic family with multiple poles / Garijo, Antoni (Universitat Rovira i Virgili. Departament d'Enginyeria Informàtica i Matemàtiques) ; Marotta, Sebastian M. (University of the Pacific(Stockon). Department of Mathematics) ; Russell, Elizabeth D. (United States Military Academy West Point. Department of Mathematical Sciences)
We consider the quadratic family of complex maps given by qc(z) = z2 + c where c is the center of a hyperbolic component in the Mandelbrot set. Then, we introduce a singular perturbation on the corresponding bounded superattracting cycle by adding one pole to each point in the cycle. [...]

112 p, 4.9 MB Connectivity of Julia sets of transcendental meromorphic functions / Taixés, Jordi ; Fagella Rabionet, Núria, dir. (Universitat de Barcelona. Grup de Sistemes Dinàmics) ; Jarque i Ribera, Xavier, dir. (Universitat de Barcelona)
Newton's method associated to a complex holomorphic function f is defined by the dynamical system Nf(z) = z - f(z) / f'(z). As a root-finding algorithm, a natural question is to understand the dynamics of Nf about its fixed points, as they correspond to the roots of the function f. [...]
