Short-time critical dynamics of the Baxter-Wu model
We study the early time behavior of the Baxter-Wu model, an Ising model with
three-spin interactions on a triangular lattice. Our estimates for the dynamic
exponent are compatible with results recently obtained for two models which
belong to the same universality class of the Baxter-Wu model: the
two-dimensional four-state Potts model and the Ising model with three-spin
interactions in one direction. However, our estimates for the dynamic exponent
of the Baxter-Wu model are completely different from the values
obtained for those models. This discrepancy could be related to the absence of
a marginal operator in the Baxter-Wu model.Comment: 7 pages, 11 figures, accepted for publication in Phys. Rev.

Seroepidemiology of group A rotavirus in suburban São Paulo, Brazil
Age-specifc patterns of rotavirus infection were investigated using a randomly selected and
representative sample of sera from a suburban community of São Paulo, Brazil screened for
class-specifc antibodies to group A rotavirus. Age-serology of anti-rotavirus IgG showed
primary infection predominant in young infants with a median age of around 18 months
consistent with IgM serology suggesting highest rates of recent infection between ages 4 and 48
months. Anti-rotavirus serum IgA prevalence increased gradually with age. Paired samples
from infants, collected 1 month apart, indicated high exposure rates with seroconversion
occurring in several infants during the reported low transmission season. Between 5 and 10%
of adults had elevated IgM levels indicative of recent infection and, potentially, of an
important contribution adults may play to rotavirus transmission. Further understanding of the
dynamics of rotavirus transmission within populations, at group and serotype level, would
benefit the design and monitoring of future immunization programmes
Challenges in Signal Analysis of Resonant-Mass Gravitational Wave Detectors
An overview of the main points related to data analysis in resonant-mass
gravitational wave detectors will be presented. Recent developments on the data
analysis system for the Brazilian detector SCHENBERG will be emphasized.Comment: 6 pages, 3 figures, presented at the international conference "100

Femtoscopic correlations in multiparticle production and beta-decay
The basics of formalism of femtoscopic and spectroscopic correlations are
given, the orthogonal character of these correlations is stressed. The
similarity and difference of femtoscopic correlations in multiparticle
production and beta-decay is discussed.Comment: 8 pages, 3 figures, Workshop on Particle correlations and Femtoscopy

Coupling constants of and processes
We calculate the coupling constants of and vertices using
the QCD sum rules technique. We compare results obtained in the limit of SU(4)
symmetry and found that the symmetry is broken on the order of 40%.Comment: 4 pages, 3 ps figures. Talk presented in the 18 Workshop on Hadron
