Kinetic stability of membrane proteins
(Springer Verlag, 2017-10)
Although membrane proteins constitute an important class of biomolecules involved in key cellular processes, study of the thermodynamic and kinetic stability of their structures is far behind that of soluble proteins. It ...
Loschmidt echo in many-spin systems: A quest for intrinsic decoherence and emergent irreversibility
(IOP Publishing, 2017-02-13)
If a magnetic polarization excess is locally injected in a crystal of interacting spins in thermal equilibrium, this 'excitation' would spread as consequence of spin-spin interactions. Such an apparently irreversible process ...
Global-local HROM for non-linear thermal problems with irreversible changes of material states
(Elsevier France-editions Scientifiques Medicales Elsevier, 2018-07)
Highly concentrated moving nonlinearities are extremely difficult to solve numerically. The Selective Laser Melting Additive Manufacturing process is a problem of this kind. A material global-local scheme is proposed, which ...
Thermal cycling effects on static and dynamic properties of a phase separated manganite
(Elsevier Science, 2018-06)
In this work we address the interplay between two phenomena which are signatures of the out-of-equilibrium state in phase separated manganites: irreversibility against thermal cycling and aging/rejuvenation process. The ...
Nonequilibrium critical behavior of magnetic thin films grown in a temperature gradient
(IOP Publishing, 2012-08)
We investigate the irreversible growth of (2+1)-dimensional magnetic thin films under the influence of a transverse temperature gradient, which is maintained by thermal baths across a direction perpendicular to the direction ...
Effective temperature from fluctuation-dissipation theorem in systems with bipartite eigenmode entanglement
(American Physical Society, 2015-01)
In thermal equilibrium, the fluctuation-dissipation theorem relates the linear response and correlation functions in a model and observable independent fashion. Out of equilibrium, these relations still hold if the equilibrium ...
Thermal stability of the plasma membrane calcium pump: Quantitative analysis of its dependence on lipid-protein interactions
(Springer, 2000-02)
Thermal stability of plasma membrane Ca2+ pump was systematically studied in three micellar systems of different composition, and related with the interactions amphiphile-protein measured by fluorescence resonance energy ...
Thermal cycling memory in phase separated manganites
(Elsevier, 2019-06)
We have studied the irreversibility of the magnetization induced by thermal cycles in La0.5Ca0.5MnO3 manganites, which present a low temperature state characterized by the coexistence of phases. The effect is evidenced by ...
Thermal stability of CopA, a polytopic membrane protein from the hyperthermophile Archaeoglobus fulgidus
(Elsevier Science Inc., 2008-03)
Despite recent progress in understanding membrane protein folding, little is known about the mechanisms stabilizing these proteins. Here we characterize the kinetic thermal stability of CopA, a thermophilic P(IB)-type ...
Phenotypic plasticity in the energy metabolism of a small Andean rodent: Effect of short-term thermal acclimation and developmental conditions
(Wiley-liss, div John Wiley & Sons Inc., 2021-07)
The study of phenotypic variation within species in response to different environments is a central issue in evolutionary and ecological physiology. Particularly, ambient temperature is one of the most important factors ...
