Remarks on transient photon production in heavy ion collisions
E. Fraga, F. Gelis, D. Schiff
In this note, we discuss the derivation of a formula that has been used in the literature in order to compute the number of photons emitted by a hot or dense system during a finite…
Quantum features in statistical observations of "timeless" classical systems
Hans-Thomas Elze
We pursue the view that quantum theory may be an emergent structure related to large space-time scales. In particular, we consider classical Hamiltonian systems in which the intrin…
On the trace anomaly and the energy-momentum conservation of quantum fields at D=2 in classical curved backgrounds
M. Alves, J. Barcelos-Neto
We study the conformal symmetry and the energy-momentum conservation of scalar field interacting with a curved background at D=2. We avoid to incorporate the metric determinant int…
Asymptotic regularity conditions for the strong convergence towards weak limit sets and weak attractors of the 3D Navier-Stokes equations
Ricardo Rosa
The asymptotic behavior of solutions of the three-dimensional Navier-Stokes equations is considered on bounded smooth domains with no-slip boundary conditions or on periodic domain…
Gas Physics, Disk Fragmentation, and Bulge Formation in Young Galaxies
Andreas Immeli, Markus Samland, Ortwin Gerhard +1
We investigate the evolution of star-forming gas-rich disks, using a 3D chemodynamical model including a dark halo, stars, and a two-phase interstellar medium with feedback process…
Thermodynamics of Abelian Gauge Fields in Real Hyperbolic Spaces
A A Bytsenko, V S Mendes, A C Tort
We work with dimensional compact real hyperbolic space with universal covering and fundamental group . Therefore, is the symmetric space , where $G=SO_1(N…
On the Curvature of the Central Path of Linear Programming Theory
Jean-Pierre Dedieu, Gregorio Malajovich, Mike Shub
We prove a linear bound on the average total curvature of the central path of linear programming theory in terms on the number of independent variables of the primal problem, and i…
AdS/CFT Correspondence and string/gauge duality
Henrique Boschi-Filho, Nelson R. F. Braga
The AdS/CFT correspondence is an exact duality between string theory in anti-de Sitter space and conformal field theories on its boundary. Inspired in this correspondence some rela…
Nonequivalent Seiberg-Witten maps for noncommutative massive U(N) gauge theory
Ricardo Amorim, Nelson R. F. Braga, Cristine N. Ferreira
Massive vector fields can be described in a gauge invariant way with the introduction of compensating fields. In the unitary gauge one recovers the original formulation. Although t…
Recent Investigations of Cascaded GEM and MHSP detectors
R. Chechik, A. Breskin, G. P. Guedes +6
We present results from our recent investigations on detectors comprising cascaded gas electron multipliers (GEM) and cascaded GEMs with micro-hole and strip (MHSP) electrodes. We…
Embedding Commutative and Noncommutative Theories in the Symplectic Framework
Clifford Neves, Wilson Oliveira, Davi C. Rodrigues +1
This paper is devoted to study gauge embedding of either commutative and noncommutative theories in the framework of the symplectic formalism. We illustrate our ideas in the Proca…
I-V curves and intergranular flux creep activation energy in the magnetic superconductor RuSr2GdCu2O8
S. Garcia, L. Ghivelder
A systematic study of I-V characteristic curves for RuSr2GdCu2O8 [Ru-(1212)] is presented, with magnetic fields up to 3 T and 5 K<T<30 K, in the region of the superconducting trans…
A layering model for superconductivity in the borocarbides
Thereza Paiva, Mohammed El-Massalami, Raimundo R. dos Santos
We propose a superlattice model to describe superconductivity in layered materials, such as the borocarbide families with the chemical formulæ BC and BC, with bei…
Casimir-Polder interaction in the presence of parallel walls
F. C. Santos, J. J. Passos Sobrinho, A. C. Tort
Making use of the quantum correlators associated with the Maxwell field vacuum distorted by the presence of plane parallel material surfaces we derive the Casimir-Polder interactio…
HYPER and gravitational decoherence
Serge Reynaud, Brahim Lamine, Astrid Lambrecht +2
We study the decoherence process associated with the scattering of stochastic backgrounds of gravitational waves. We show that it has a negligible influence on HYPER-like atomic in…
A measurement of the branching fractions of the b-quark into charged and neutral b-hadrons
The DELPHI Collaboration, J. Abdallah
The production fractions of charged and neutral b-hadrons in b-quark events from Z0 decays have been measured with the DELPHI detector at LEP. An algorithm has been developed, base…
Fibrations et conjecture de Tate
Marc Hindry, Amilcar Pacheco, Rania Wazir
We describe the behaviour of the rank of the Mordell-Weil group of the Picard variety of the generic fibre of a fibration in terms of local contributions given by averaging traces…
Casimir effect for the scalar field under Robin boundary conditions: A functional integral approach
Luiz C. de Albuquerque, R. M. Cavalcanti
In this work we show how to define the action of a scalar field in a such a way that Robin boundary condition is implemented dynamically, i.e., as a consequence of the stationary a…
Isometries of a D3-brane space
Henrique Boschi-Filho, Nelson R. F. Braga
We obtain the Killing equations and the corresponding infinitesimal isometries for the ten dimensional space generated by a large number of coincident D3-branes. In a convenient li…
Isospin Effects in Nuclear Multifragmentation
W. P. Tan, S. R. Souza, R. J. Charity +3
We develop an improved Statistical Multifragmentation Model that provides the capability to calculate calorimetric and isotopic observables with precision. With this new model we e…
A graph model for the evolution of specificity in humoral immunity
L. E. Flores, E. J. Aguilar, V. C. Barbosa +1
The immune system protects the body against health-threatening entities, known as antigens, through very complex interactions involving the antigens and the system's own entities.…
