Medical ethics and more: Ideal theories, non-ideal theories and conscientious objection
(B M J Publishing Group, 2015-01)
Doing 'good medical ethics' requires acknowledgment that it is often practised in non-ideal circumstances! In this article I present the distinction between ideal theory (IT) and non-ideal theory (NIT). I show how IT may ...
Sobre la noción de distancia en física estadística y mecánica cuántica /
(2006-09)
Estudiamos el concepto de distancia entre distribuciones de probabilidad y sus aplicaciones en problemas relevantes de la Física y la Biología. El eje central de este trabajo de tesis lo constituye la divergencia de ...
Konishi OPE coefficient at the five loop order
(2018-11-01)
We use the method of asymptotic expansions to study the OPE limit of a fourpoint function of protected operators in N= 4 SYM. We use a new method for evaluating the resulting propagator-type integrals and then extract the ...
All five-loop planar four-point functions of half-BPS operators in N= 4 SYM
(2018-11-01)
We obtain all planar four-point correlators of half-BPS operators in N= 4 SYM up to five loops. The ansatz for the integrand is fixed partially by imposing lightcone OPE relations between different correlators. We then fix ...
Effective lagrangian for a mass dimension one fermionic field in curved spacetime
(2018-02-01)
In this work we use momentum-space techniques to evaluate the propagator G(x, x′) for a spin 1/2 mass dimension one spinor field on a curved Friedmann-Robertson-Walker spacetime. As a consequence, we built the one-loop ...
Some remarks on the attractor behaviour in ELKO cosmology
(Iop Publishing Ltd, 2014-08-01)
Recent results on the dynamical stability of a system involving the interaction of the ELKO spinor field with standard matter in the universe have been reanalysed, and the conclusion is that such system does not exhibit ...
Sistemas com dois geradores supersimétricos
(Universidade Estadual Paulista (Unesp), 2010-04-04)
Neste estudo iremos aplicar supersimetria em teorias como mecânica quântica, teoria de cordas e teoria de campos em D = 3. Apesar de todas essas teorias terem aplicações em campos completamente diferentes iremos encontrar ...

Wallace’s and Darwin’s natural selection theories
(Springer, 2017-07)
This work takes a stand on whether Wallace should be regarded as co-author of the theory of natural selection alongside Darwin as he is usually considered on behalf of his alleged essential contribution to the conception ...
