Derivatives and integrals: matrix order operators as an extension of the fractional calculus
C. B. da Porciuncula
A natural consequence of the fractional calculus is its extension to a matrix order of differentiation and integration. A matrix-order derivative definition and a matrix-order inte…
Dataset after seven years simulating hybrid energy systems with Homer Legacy
Alexandre Beluco, Frederico A. During Filho, Lucia M. R. Silva +8
Homer Legacy software is a well-known software for simulation of small hybrid systems that can be used for both design and research. This dataset is a set of files generated by Hom…
A network model for clonal differentiation and immune memory
Alexandre de Castro
A model of bit-strings, that uses the technique of multi-spin coding, was previously used to study the time evolution of B-cell clone repertoire, in a paper by Lagreca, Almeida and…
The dawn of mathematical biology
Daniel Sander Hoffmann
In this paper I describe the early development of the so-called mathematical biophysics, as conceived by Nicolas Rashevsky back in the 1920's, as well as his latter idealization of…
On the Optimal Design of Triple Modular Redundancy Logic for SRAM-based FPGAs
F. Lima Kastensmidt, L. Sterpone, L. Carro +1
Triple Modular Redundancy (TMR) is a suitable fault tolerant technique for SRAM-based FPGA. However, one of the main challenges in achieving 100% robustness in designs protected by…
Heavy Quarks and Meson Production in Ultraperipheral Heavy Ion Collisions
V. P. Goncalves, M. V. T. Machado
We report on our recent investigations in photonuclear production of heavy quarks and vector meson in ultraperipheral heavy ion collisions. In particular, our theoretical predictio…
Investigating F_L(x,Q2) at fixed energy in the color dipole formalism
Magno V. T. Machado
At small-x, the structure function F_L(x,Q2) is driven by the gluon content of the nucleon target and consequently it can unravel the underlying QCD dynamics in that region. In thi…
Coherent photon-hadron interactions in pA collisions: Small-x physics after HERA
V. P. Goncalves, M. V. T. Machado
In this letter we study the photoproduction of heavy quarks and vector mesons in the coherent proton-nucleus (pA) interactions for RHIC and LHC energies and analyze if these proces…
The QCD Pomeron in Ultraperipheral Heavy Ion Collisions: V. Double Vector Meson Production in the BFKL Approach
V. P. Goncalves, M. V. T. Machado, W. K. Sauter
In this work the double vector meson production in ultraperipheral heavy ion collisions is investigated within the BFKL approach. The integrated cross sections and event rates for…
Vector Meson Production in Ultraperipheral Heavy Ion Collisions
V. P. Goncalves, M. V. T. Machado
The ultraperipheral heavy ion collisions (UPC's) are an important alternative to study the QCD dynamics until the next generation of colliders become reality. Du…
Geometric scaling in ultrahigh energy neutrinos and nonlinear perturbative QCD
Magno V. T. Machado
It is shown that in ultrahigh energy inelastic neutrino-nucleon(nucleus) scattering the cross sections for the boson-hadron(nucleus) reactions should exhibit geometric scaling on t…
The QCD Pomeron in Ultraperipheral Heavy Ion Collisions: IV. Photonuclear Production of Vector Mesons
V. P. Goncalves, M. V. T. Machado
The photonuclear production of vector mesons in ultraperipheral heavy ion collisions is investigated within the QCD color dipole picture, with particular emphasis on the saturation…
From ballistic to Brownian vortex motion in complex oscillatory media
Jörn Davidsen, Ronaldo Erichsen, Raymond Kapral +1
We show that the breaking of the rotation symmetry of spiral waves in two-dimensional complex (period-doubled or chaotic) oscillatory media by synchronization defect lines (SDL) is…
Heavy quark photoproduction in proton-proton collisions
V. P. Goncalves, M. V. T. Machado
We calculate the photoproduction of heavy quarks in proton-proton collisions at RHIC, Tevatron and LHC energies. The integrated cross section and the rapidity distributions for ope…
A phenomenological analysis of the longitudinal structure function at small and low
V. P. Goncalves, M. V. T. Machado
The longitudinal structure function in deep inelastic scattering is one of the observables from which the gluon distribution can be unfolded. Consequently, this observable can be u…
Discovery of three optical open clusters in the Galaxy
E. Bica, C. Bonatto, C. M. Dutra
We report the discovery of three optical open clusters in the Milky Way. Two clusters are in Scutum (Cluster1 at l=18.44 degrees and b=-0.42 degrees, and Cluster2 at l=19.60 degree…
Nuclear exclusive vector meson photoproduction
V. P. Goncalves, M. V. T. Machado
We calculate the nuclear cross section for vector meson exclusive photoproduction within the QCD color dipole picture and in the Regge approach. For the former approach, we have co…
On the calibration of the COBE/IRAS dust emission reddening maps
C. M. Dutra, A. V. Ahumada, J. J. Claria +3
In this work we study the spectral properties (3600 - 6800 A) of the nuclear region of early-type galaxies at low (|b|<25, intermediate (including surroundings of the Magellanic Cl…
NTT infrared imaging of star cluster candidates towards the central parts of the Galaxy
C. M. Dutra, S. Ortolani, E. Bica +3
We address the issue whether the central parts of the Galaxy harbour young clusters other than Arches, Quintuplet and the Nuclear Young Cluster. A large sample of centrally project…
The High Density Effects in Heavy Quark Production at pA Colliders
A. L. Ayala Filho, V. P. Goncalves
In this paper we investigate the role of the high density effects in the heavy quark production cross section in processes at RHIC and LHC. We use, as initial condition, a glu…
