The contribution of the pairing field to the transfer of two nucleons
(Elsevier Science, 2019-03)
The treatment of pairing interactions in systems with a finite number of particles, like the atomic nucleus, was originally performed by applying the BCS transformations in the energy representation. An alternative method, ...
Inferred kinship patterns reveal low levels of extra-pair paternity in the endangered Neotropical Jabiru Stork (Jabiru mycteria, Aves: Ciconiiformes)
(Springer, 2013-04)
The present study inferred the genetic mating system in a natural breeding population of the Jabiru Stork (Jabiru mycteria), a Neotropical wading bird considered endangered in part of its distribution range. Based on data ...
Neutrino-pair interactions in astrophysical systems
(World Scientific, 2020-10)
We study the effects produced by interactions among neutrinos upon extra-galactic neutrino-fluxes. We have assumed a separable type of pair interactions and performed a transformation to a quasi-particle mean field followed ...
Lifetime reproductive efficiency of BALB/c mouse pairs after an environmental modification at 3 mating ages
(Amer Assoc Laboratory Animal Science, 2015-01-01)
The aim of this study was to evaluate the effects of an environment change and the age at which mating pairs were formed on the lifetime reproductive performance of BALB/c mice. We assigned 60 monogamous pairs to a randomized ...

Collective effects in biphoton generation of a four-wave-mixing process
(Universidade Federal de São CarlosUFSCarCâmpus São CarlosFísica - F, 2022-04-28)
The generation of biphotons remains an important field of research, as several applications require such sources. For instance, some of their properties are fundamental in quantum communication, quantum computing, and ...
Effects of the electron–hole pair in Auger and X-ray photoemission spectroscopy from surfaces of Fe–Si
(Elsevier Science, 2015-02)
In this work, we investigate in detail the effects due to the interaction between an electron and a stationary positive ion (or atomic hole) in the neighborhood of a surface of Fe–Si, having a strong plasmon peak in their ...
