Scalar resonances in a unitary pi pi S-wave model for D(+)->pi(+)pi(-)pi(+)
(AMER PHYSICAL SOC, 2009)
We propose a model for D(+)->pi(+)pi(-)pi(+) decays following experimental results which indicate that the two-pion interaction in the S wave is dominated by the scalar resonances f(0)(600)/sigma and f(0)(980). The weak ...
Tipos de tricomas em genótipos de Lycopersicon
(Associação Brasileira de Horticultura, 2001-11-01)
Foram identificados os tipos de tricomas em alguns genótipos de Lycopersicon, utilizando microscópio eletrônico de varredura. Foram utilizados os genótipos L. hirsutum (PI 127826 e PI 127827), L. hirsutum var. glabratum ...
On the Relaxation Mechanisms of 6-Azauracil
(AMER CHEMICAL SOC, 2011)
The nonadiabatic photochemistry of 6-azauracil has been studied by means of the CASPT2//CASSCF protocol and double-zeta plus polarization ANO basis sets. Minimum energy states, transition states, minimum energy paths, and ...
Shear viscosity of a pion gas resulting from rho pi pi and sigma pi pi interactions
(Amer Physical Soc, 2014-04-02)
We have evaluated the shear viscosity of pion gas with vanishing chemical potential taking into account its scattering with the low mass resonances sigma and rho during propagation in the medium. The thermal width (or ...
On the Mechanisms of Triplet Excited State Population in 8-Azaadenine
(AMER CHEMICAL SOCWASHINGTON, 2012)
The photophysics of 8-azaadenine (8-AA) has been studied with the CASPT2//CASSCF protocol and ANO-L double-zeta basis sets. Stationary equilibrium structures, surface crossings, minimum energy paths, and linear interpolations ...

PTEN Regulates PI(3,4)P2 Signaling Downstream of Class I PI3K
The PI3K signaling pathway regulates cell growth and movement and is heavily mutated in cancer. Class I PI3Ks synthesize the lipid messenger PI(3,4,5)P3. PI(3,4,5)P3 can be dephosphorylated by 3- or 5-phosphatases, the ...
