Segurança internacional e normatividade: é o liberalismo o elo perdido dos critical securities studies?
(CEDEC, 2008)
O surgimento, e afirmação, de uma corrente de estudos críticos em segurança internacional plantou firmemente a idéia de que os problemas de segurança internacional não estão meramente relacionados com aspectos objetivos ...
Ground state solution for differential equations with left and right fractional derivatives
(Wiley & Sons, 2015)
In this work, we study the existence of positive solutions for a class of fractional differential equation given by
D-t(infinity-infinity)alpha D(t)(alpha)u(t) + u(t) = f(t,u(t)),
u is an element of H-alpha (R), ...
Metallic quantum critical points with finite BCS couplings
(American Physical Society, 2015-11-02)
We study the fate of superconductivity in the vicinity of a class of metallic quantum critical points obtained by coupling a Fermi surface to a critical boson. In such systems there is a competition between the enhanced ...
Critical velocity determined by a non-exhaustive method in menopausal women
(2015-01-01)
The aim of the present study was to test the reproducibility of critical velocity determined in a non-exhaustive method (CVNE) and its relationship with the maximal lactate steady state (MLSS) in menopausal women. Methods: ...

Brain Organization into Resting State Networks Emerges at Criticality on a Model of the Human Connectome
(Amer Physical Soc, 2013-04-26)
The relation between large-scale brain structure and function is an outstanding open problem in neuroscience. We approach this problem by studying the dynamical regime under which realistic spatiotemporal patterns of brain ...
Tri-critical behavior of the Blume Capel model on a diamond lattice
(Elsevier B.V., 2017-02-01)
The mean field approximation results are obtained in a five-site cluster on the diamond lattice from the Bogoliubov inequality. Spin correlation identities for the Blume-Capel model on diamond lattice are derived from a ...
Footprint of a topological phase transition on the density of states
(2023)
For a generalized Su–Schrieffer–Heeger model, the energy zero is always critical and hyperbolic in the sense that all reduced transfer matrices commute and have their spectrumofftheunitcircle.Disorder-driventopologicalph ...
On the critical forcing amplitude of forced nonlinear oscillators
(De Gruyter, 2013-12)
The steady-state response of forced single degree-of-freedom weakly nonlinear oscillators under primary resonance conditions can exhibit saddle-node bifurcations, jump and hysteresis phenomena, if the amplitude of the ...
