Dynamics of algebras in quantum unstable systems
(World Scientific, 2018-07)
We introduce a dynamical evolution operator for dealing with unstable physical process, such as scattering resonances, photon emission, decoherence and particle decay. With that aim, we use the formalism of rigged Hilbert ...
On the entropy for unstable fermionic and bosonic states
(Elsevier, 2014-03)
We focus on the calculation of the entropy for decaying states in non-relativistic quantum mechanics. The starting point is the Friedrichs model in second quantization language. In this model, the Hamiltonian admits a ...
Identifying unstable taxa: Efficient implementation of triplet-based measures of stability, and comparison with Phyutility and RogueNaRok
(Elsevier Inc, 2015-07)
This paper describes an efficient implementation of triplet-based measures of stability, in the program TNT. The only available implementations of such measures are much slower than the present one, either because of an ...
Excision of an Unstable Pathogenicity Island in Salmonella enterica Serovar Enteritidis Is Induced during Infection of Phagocytic Cells
(2011)
The availability of the complete genome sequence of several Salmonella enterica serovars has revealed the presence of unstable genetic elements in these bacteria, such as pathogenicity islands and prophages. This is the ...
Hemoglobina Köln diagnosticada em programa de triagem neonatal em São José do Rio Preto, SP
(2002-12-01)
Hemoglobinopathies are a diverse group of inherited recessive disorders that include thalassemias and sickle cell disease. They were the first genetic diseases to be characterized at the molecular level and consequently ...
