Absorptive one-loop corrections and the complex-mass prescription for the Δ resonance propagator
(IOP Publishing, 2012-07)
It is shown that the absorptive one-loop self-energy corrections to the δ ++ propagator can reproduce the complex-mass prescription for its resonant form. The effects of absorptive corrections beyond the ones considered ...
PROPAGATOR FOR THE DELTA-FUNCTION POTENTIAL MOVING WITH CONSTANT VELOCITY

About the validity of complex mass scheme for the Δ resonance and higher energy region approaches
(IOP Publishing, 2015-09)
It is a well known fact that when a resonance (R) is produced and decays, its unperturbed propagator will be singular at p2 mR = 2 when it appears in an s-type Feynman pole graph. Nevertheless this is not a problem, since ...

Absence of point spectrum for unitary operators
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
Let us consider the time-dependent Schrodinger equation,
Adiabaticity and gravity theory independent conservation laws for cosmological perturbations
(Elsevier, 2016)
We carefully study the implications of adiabaticity for the behavior of cosmological perturbations. There are essentially three similar but different definitions of non-adiabaticity: one is appropriate for a thermodynamic ...
Evaluación del comportamiento de guías de álamo, al séptimo año, en un sistema silvopastoril del Delta del río Paraná
(2014-03-18)
Los Sistemas Silvopastoriles (SSP) bajo álamos en el Bajo Delta del Paraná requieren de
nuevas estrategias de manejo. La combinación de la alta palatabilidad de sus hojas,
especialmente durante los meses de primavera, ...
Subcritical fatigue in fuse networks
(EPL ASSOCIATION, EUROPEAN PHYSICAL SOCIETYMULHOUSE, 2012)
We obtain the Paris law of fatigue crack propagation in a fuse network model where the accumulated damage in each resistor increases with time as a power law of the local current amplitude. When a resistor reaches its ...
Consistence between πn Δ spin-3/2 gauge couplings and electromagnetic gauge invariance
(IOP Publishing, 2015-11)
We review the consistency between the recently proposed spin-3/2 gauge interaction for Δ resonance with nucleons (N) and pions (π), and the fundamental electromagnetic gauge invariance in any radiative amplitude. We show ...
Studies on structural, morphological and electrical properties of Ce1-xErxO2-delta (x=0.05-0.20) as solid electrolyte for IT - SOFC
(Elsevier B.V., 2015-03-01)
A series of four different powders ceria doped Ce1-xErxO2-delta (0.05 <= x <= 0.20) were synthesized by applying self-propagating reaction at room temperature (SPRT method). SPRT procedure is based on the self-propagating ...
