Abel maps of Gorenstein curves
Lucia Caporaso, Juliana Coelho, Eduardo Esteves
For a Gorenstein curve X and a nonsingular point P of X, we construct Abel maps A from X to J_X^1 and A_P from X to J_X^0, where J_X^i is the moduli scheme for simple, torsion-free…
Free curves and periodic points for torus homeomorphisms
Alejandro Kocsard, Andres Koropecki
We study the relationship between free curves and periodic points for torus homeomorphisms in the homotopy class of the identity. By free curve we mean a homotopically nontrivial s…
Newhouse phenomenon and homoclinic classes
Jiagang Yang
We show that for a residual subset of diffeomorphisms far away from tangency, every non-trivial chain recurrent class that is accumulated by sources ia a homoclinic class con…
Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei
The Pierre Auger Collaboration
Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the highest energies, which are correlated with the…
Upper limit on the diffuse flux of UHE tau neutrinos from the Pierre Auger Observatory
The Pierre Auger Collaboration
The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau-neutrinos that interact in the Earth's crust. Tau leptons from charged-cur…
Transport modulation of graphene nanoribbons with side-attached organic molecules
L. Rosales, M. Pacheco, Z. Barticevic +2
In this work we address the effects on the conductance of graphene nanoribbons (GNRs) at which organic molecules are side-attached on the ribbon ends. For simplicity, only armchair…
Maximal and minimal height distributions of fluctuating interfaces
T. J. Oliveira, F. D. A. Aarao Reis
We study numerically the maximal and minimal height distributions (MAHD, MIHD) of the nonlinear interface growth equations of second and fourth order and of related lattice models…
Hadron production in non linear relativistic mean field models
M. Chiapparini, M. E. Bracco, A. Delfino +3
By using a parametrization of the non-linear Walecka model which takes into account the binding energy of different hyperons, we present a study of particle production yields measu…
Gauss-Codazzi Formalism to Braneworld Scenario within Brans-Dicke Theory
M. C. B. Abdalla, M. E. X. Guimaraes, J. M. Hoff da Silva
We apply the Gauss-Codacci formalism to brane worlds scenario within the framework of Brans-Dicke gravity. The compactification is taken from six to five dimensions in order to for…
Aspects of nonmetricity in gravity theories
R. F. Sobreiro, V. J. Vasquez Otoya
In this work, we show that a class of metric-affine gravities can be reduced to a Riemann-Cartan one. The reduction is based on the cancelation of the nonmetricity against the symm…
Time-dependent magnetohydrodynamic self-similar extragalactic jets
K. H. Tsui, A. Serbeto
Extragalactic jets are visualized as dynamic erruptive events modelled by time-dependent magnetohydrodynamic (MHD) equations. The jet structure comes through the temporally self-si…
Does Sex Induce a Phase Transition?
P. M. C. de Oliveira, S. Moss de Oliveira, D. Stauffer +2
We discovered a dynamic phase transition induced by sexual reproduction. The dynamics is a pure Darwinian rule with both fundamental ingredients to drive evolution: 1) random mutat…
Seiberg-Witten map for the 4D noncommutative BF theory
L. C. Q. Vilar, O. S. Ventura, R. L. P. G. Amaral +2
We describe the Seiberg-Witten map for the 4D noncommutative BF theory (NCBF). We establish the existence of a map taking the abelian NCBF into its commutative version, in agreemen…
A computer simulation of language families
Paulo Murilo Castro de Oliveira, Dietrich Stauffer, Soeren Wichmann +1
This paper presents Monte Carlo simulations of language populations and the development of language families, showing how a simple model can lead to distributions similar to the on…
Introduction to shape stability for a storage model
M. V. Menshikov, V. V. Sisko, M. Vachkovskaia
We consider a new idea for a storage model on n nodes, namely stability of shape. These nodes support K neighborhoods S_i \subset {1, ..., n} and items arrive at the S_i as indepen…
Constraining relativistic models through heavy ion collisions
D. P. Menezes, C. Providencia, M. Chiapparini +3
Relativistic models can be successfully applied to the description of compact star properties in nuclear astrophysics as well as to nuclear matter and finite nuclei properties, the…
Possible evidence of a ground level enhancement of muons in association with a SWIFT Trigger
C. R. A. Augusto, C. E. Navia, M. B. Robba +1
Starting from April 2007, a search for solar daily variation of the muon intensity ( GeV) at sea level and using two directional muon telescopes is in progress. In this su…
Probing singularities in quantum cosmology with curvature scalars
G. Oliveira Neto, E. V. Correa Silva, N. A. Lemos +1
We provide further evidence that the canonical quantization of cosmological models eliminates the classical Big Bang singularity, using the {\it DeBroglie-Bohm} interpretation of q…
The Analytic Classification of Plane Branches
Abramo Hefez, Marcelo E. Hernandes
In this paper we give a solution to Zariski's problem of analytic classification of plane branches.
Dewetting of a solid monolayer
Olivier Pierre-Louis, Anna Chame, Yukio Saito
We report on the dewetting of a monolayer on a solid substrate, where mass transport occurs via surface diffusion. For a wide range of parameters, a labyrinthine pattern of bilayer…
Dynamical invariants and nonadiabatic geometric phases in open quantum systems
M. S. Sarandy, E. I. Duzzioni, M. H. Y. Moussa
We introduce an operational framework to analyze non-adiabatic Abelian and non-Abelian, cyclic and non-cyclic, geometric phases in open quantum systems. In order to remove the adia…
Towards an hybrid compactification with a scalar-tensor global cosmic string
M. C. B. Abdalla, M. E. X. Guimaraes, J. M. Hoff da Silva
We derive a solution of the gravitational equations which leads to a braneworld scenario in six dimensions using a global cosmic string solution in a low energy effective string th…

F. A. Silveira, F. D. A. Aarão Reis
We study roughness scaling of the outer surface and the internal porous structure of deposits generated with the three-dimensional bidisperse ballistic deposition (BBD), in which p…

Daniel Reyes, Mucio A. Continentino
We obtain the phase diagram and thermodynamic behavior of the Kondo necklace model for arbitrary dimensions using a representation for the localized and conduction electrons in…
