Barbieri, A., Brower, E., Estabrook, P., Gibbs, R., Horttor, R., ...
NASA and ESA have established an international network of Mars orbiters, outfitted with relay communications payloads, to support robotic exploration of the red planet. Starting in January, 2004,...
Gravitational helicity interaction (2005)
For gravitational deflections of massless particles of given helicity from a classical rotating body, we describe the general relativity corrections to the geometric optics approximation. We compute...
Brain SPECT imaging in Sydenham's chorea (2002)
Barsottini,O.G.P., Ferraz,H.B., Seviliano,M.M., Barbieri,A.
The objective of the present study was to determine whether brain single-photon emission computed tomography (SPECT) imaging is capable of detecting perfusional abnormalities. Ten Sydenham's chorea...
Scintigraphy and Doppler ultrasonography for the evaluation of obstructive urinary calculi (2001)
Gandolpho,L., Sevillano,M., Barbieri,A., Ajzen,S., Schor,N., Ortiz,V., ...
Forty-seven patients with unilateral obstructive calculi (12 males and 35 females) were submitted to 99mTc-diethylene triamine pentaacetic acid (DTPA) or 99mTc-dimercaptosuccinic acid (DMSA) scans...
Teste de esforço: alterações do segmento ST restritas à fase de recuperação (1999)
Oliveira Fº,J. A., Luna Fº,B., Salles,T., Brito,R., Palma,L., Barbieri,A., ...
OBJETIVO: Determinar a incidência de doença coronária aterosclerótica (DCA) e/ou isquemia miocárdica em pacientes (pt) com alterações do segmento ST restritas à fase de recuperação (ASTRR)...
Space of the vertices of relativistic spin networks (1997)
The general solutin to the constraints that define relativistic spin networks vertices is given and their relations with 3-dimensional quantum tetrahedra is dicussed. An alternative way to handle the...
Quantum tetrahedra and simplicial spin networks (1997)
A new link between tetrahedra and the group SU(2) is pointed out: by associating to each face of a tetrahedron an irreducible unitary SU(2) representation and by imposing that the faces close, the...
Holons in Chiral Spin-Liquids: Statistics and Pairing (1993)
Deaven, D. M., Rokhsar, D. S., Barbieri, A.
We study Gutzwiller-projected variational wavefunctions for charged, spinless holon excitations in chiral spin liquids. We find that these states describe anyons, with a statistical phase $\Phi_s$...

Myocardial perfusion scintigraphy and coronary disease risk factors in systemic lupus erythematosus
Sella, E, Sato, E, Leite, W, Filho, J, Barbieri, A
Objective: To evaluate the prevalence of myocardial perfusion abnormalities and the possible association between myocardial perfusion defects and traditional coronary artery disease (CAD) risk...
Lucchelli, A, Santagostino-Barbone, M G, Barbieri, A, Candura, S M, Tonini, M
1. A combined study of receptor binding in central neuronal cell membranes and functional responses in isolated segments of guinea-pig small intestine allowed characterization of the interaction of...
Lucchelli, A., Santagostino-Barbone, M. G., Barbieri, A., Tonini, M.
1. Experiments were carried out to characterize the receptors mediating the indirect excitatory response to 5-hydroxytryptamine (5-HT) in the guinea-pig isolated trachea. 2. 5-HT caused...
