An extension of the concept of gradient semigroups which is stable under perturbation
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
In this article we introduce the concept of a gradient-like nonlinear semigroup as an intermediate concept between a gradient nonlinear semigroup (those possessing a Lyapunov function, see [J.K. Hale, Asymptotic Behavior ...
Modifier adaptation with guaranteed feasibility in the presence of gradient uncertainty
(Pergamon-Elsevier Science Ltd, 2017-01)
In the context of real-time optimization, modifier-adaptation schemes use estimates of the plant gradients to achieve plant optimality despite plant-model mismatch. Plant feasibility is guaranteed upon convergence, but not ...
The effect of reactions on the formation and readout of the gradient of Bicoid
(IOP Publishing, 2017-02)
During early development, the establishment of gradients of transcriptional factors determinesthe patterning of cell fates. The case of Bicoid (Bcd) in Drosophila melanogaster embryos is welldocumented and studied. There ...
Soluções invariantes para quase solitons gradientes de Ricci e solitons gradientes de Yamabe conformes a um espaço pseudo-Euclidiano
(2021-05-20)
Baseado em [16] e [17], apresentamos nesta dissertação um estudo de classificação de quase solitons gradientes de Ricci e solitons gradientes de Yamabe. No primeiro caso, estudamos a classificação de quase solitons gradientes ...
The stellar metallicity gradients in galaxy discs in a cosmological scenario
(2016)
Context. The stellar metallicity gradients of disc galaxies provide information on disc assembly, star formation processes, and chemical evolution. They also might store information on dynamical processes that could affect ...
Geometrical localization analysis of gradient-dependent parabolic Drucker -Prager elastoplasticity
(Pergamon-Elsevier Science Ltd, 2006-12)
In this work the geometrical method for the analysis of the localization properties of the thermodynamically consistent gradient--dependent parabolic Drucker-Prager elastoplastic model is presented. From the analytical ...
Evaluación del gradiente intraventricular durante ejercicio en pacientes con miocardiopatía hipertrófica no obstructiva
