Meson decay in the Fock-Tani Formalism

The Fock-Tani formalism is a first principle method to obtain effective interactions from microscopic Hamiltonians. Usually this formalism was applied to scattering, here we introduced it to calculate partial decay widths for mesons.Comment: Presented at HADRON05 XI.

Glueball-glueball scattering in a constituent gluon model

In this work we use a mapping technique to derive in the context of a constituent gluon model an effective Hamiltonian that involves explicit gluon degrees of freedom. We study glueballs with two gluons using the Fock-Tani formalism. In the present work we consider two possibilities for $0^{++}$: (i) as a pure $s\bar{s}$ and calculate, in the context of a quark interchange picture, the cross-section; (ii) as a glueball where a new calculation for this cross-section is made, in the context of the constituent gluon model, with gluon interchange.Comment: Proceedings of the International Workshop IX Hadron Physics and VII Relativistic Aspects of Nuclear Physics (HADRON-RANP 2004

Evaluation of de novo RNA-Seq assemblers in differential expression experiments.

The objective of this study is to evaluate methodologies applied on de novo transcriptomics studies, proposing criteria for ranking the data, in order to maximize the chance of correctly identifying a differentially expressed transcript.X-meeting 2015

Spin-orbit mode transfer via a classical analog of quantum teleportation

We translate the quantum teleportation protocol into a sequence of coherent operations involving three degrees of freedom of a classical laser beam. The protocol, which we demonstrate experimentally, transfers the polarisation state of the input beam to the transverse mode of the output beam. The role of quantum entanglement is played by a non-separable mode describing the path and transverse degrees of freedom. Our protocol illustrates the possibility of new optical applications based on this intriguing classical analogue of quantum entanglement.Comment: 5 pages, 7 figure

Fósforo e humoativo BM® no desenvolvimento, produtividade e qualidade de raízes de mandioca, em Belmonte, Bahia.

Os solos da Região Fisiográfica do Extremo Sul da Bahia, na sua maioria, apresentam fertilidade natural baixa, com níveis de nitrogênio e fósforo geralmente a níveis críticos de exigência, conduzindo a produtividades significativamente inferiores a capacidade produção das culturas. Os agricultores, em sua maioria não corrigem a fertilidade do solo, e quando o fazem, aplicam na quantidade e de forma errônea, reduzindo a capacidade de resposta das plantas.Fertilidade do solo.
