State-of-the Art Motion Estimation in the Context of 3D TV
Vania V. Estrela, Alessandra M. Coelho
Progress in image sensors and computation power has fueled studies to improve acquisition, processing, and analysis of 3D streams along with 3D scenes/objects reconstruction. The r…
On Solving Manufacturing Cell Formation via Bicluster Editing
Rian G. S. Pinheiro, Ivan C. Martins, Fábio Protti +3
This work investigates the Bicluster Graph Editing Problem (BGEP) and how it can be applied to solve the Manufacturing Cell Formation Problem (MCFP). We develop an exact method for…
Universal fluctuations in the growth of semiconductor thin films
R. A. L. Almeida, S. O. Ferreira, T. J. Oliveira +1
Scaling of surface fluctuations of polycrystalline CdTe/Si(100) films grown by hot wall epitaxy are studied. The growth exponent of surface roughness and the dynamic exponent of th…
Polyakov-Nambu-Jona-Lasinio phase diagrams and quarkyonic phase from order parameters
M. Dutra, O. Lourenço, A. Delfino +2
We show that the magnitude of the order parameters in Polyakov-Nambu-Jona-Lasinio (PNJL) model, given by the quark condensate and the Polyakov loop, can be used as a criterium to c…
Monogamy of entanglement of formation
Thiago R. de Oliveira, Marcio F. Cornelio, Felipe F. Fanchini
It is well known that a particle cannot freely share entanglement with two or more particles. This restriction is generally called monogamy. However the formal quantification of su…
Cs2NaAl1-xCrxF6: A family of compounds presenting magnetocaloric effect
S. S. Pedro, J. C. G. Tedesco, F. Yokaichiya +8
In this paper we explore the magnetocaloric effect (MCE) of chromium-doped elpasolite CsNaAlCrF (x = 0.01 and 0.62) single crystals. Our magnetization and heat…
An energy function and its application to the periodic behavior of k-reversible processes
Leonardo I. L. Oliveira, Valmir C. Barbosa, Fábio Protti
We consider the graph dynamical systems known as k-reversible processes. In such processes, each vertex in the graph has one of two possible states at each discrete time step. Each…
Generic Continuity of Metric Entropy for Volume-preserving Diffeomorphisms
Jiagang Yang, Yunhua Zhou
Let be a compact manifold and be the set of volume-preserving diffeomorphisms of . We prove that there is a residual subset $\mathcal {R}\subset \…
Derivation of capture and reaction cross sections from experimental quasi-elastic and elastic backscattering probabilities
V. V. Sargsyan, G. G. Adamian, N. V. Antonenko +1
The direct measurement of the reaction or capture (fusion) cross section is a difficult task since it would require the measurement of individual cross sections of many reaction ch…
Derivation of reaction cross sections from experimental elastic backscattering probabilities
V. V. Sargsyan, G. G. Adamian, N. V. Antonenko +1
The relationship between the backward elastic scattering probabilities and reaction cross sections is derived. This is a a very simple and useful method to extract reaction cross s…
Efficient experimental validation of photonic boson sampling against the uniform distribution
N. Spagnolo, C. Vitelli, M. Bentivegna +10
A boson sampling device is a specialised quantum computer that solves a problem which is strongly believed to be computationally hard for classical computers. Recently a number of…
Zero-Field muSR Search for a Time-Reversal-Symmetry-Breaking Mixed Pairing State in Superconducting Ba1-xKxFe2As2
Z. Lotfi Mahyari, A. Cannell, C. Gomez +6
We report the results of a zero-field muon spin relaxation (ZF-muSR) study of superconducting Ba1-xKxFe2As2 (0.5 < x < 0.9) in search of weak spontaneous internal magnetic fields a…
Incompleteness of the Hamilton-Jacobi theory
Nivaldo A. Lemos
The problem of the motion of a charged particle in an electric dipole field is used to illustrate that the Hamilton-Jacobi method does not necessarily give all solutions to the equ…
Study of the 1D anisotropic Kondo necklace model at criticality via an entanglement entropy estimator
A. Saguia
We use an estimator of quantum criticality based on the entanglement entropy to discuss the ground state properties of the 1D anisotropic Kondo necklace model. We found that the T=…
Identifying Clouds over the Pierre Auger Observatory using Infrared Satellite Data
Pierre Auger Collaboration
We describe a new method of identifying night-time clouds over the Pierre Auger Observatory using infrared data from the Imager instruments on the GOES-12 and GOES-13 satellites. W…
Nuclear astrophysics with radioactive ions at FAIR
R. Reifarth, S. Altstadt, K. Göbel +317
The nucleosynthesis of elements beyond iron is dominated by neutron captures in the s and r processes. However, 32 stable, proton-rich isotopes cannot be formed during those proces…
On the elimination of infinitesimal Gribov ambiguities in non-Abelian gauge theories
A. D. Pereira, R. F. Sobreiro
An alternative method to account for the Gribov ambiguities in gauge theories is presented. It is shown that, to eliminate Gribov ambiguities, at infinitesimal level, it is require…
Nonadiabatic quantum state engineering driven by fast quench dynamics
Marcela Herrera, Marcelo S. Sarandy, Eduardo I. Duzzioni +1
There are a number of tasks in quantum information science that exploit non-transitional adiabatic dynamics. Such a dynamics is bounded by the adiabatic theorem, which naturally im…
Observation of environment-induced double sudden transitions in geometric quantum correlations
