Active control of Alfvén eigenmodes inmagnetically confined toroidal plasmas
(IOP Publishing, 2019-03)
Article
Accés obertAlfvén waves are electromagnetic perturbations inherent to magnetized plasmas that can be driven unstable by a free energy associated with gradients in the energetic particles' distribution function. The energetic particles ... -

Assessment of the capabilities and applicability of ionospheric perturbation indices provided in Europe
(2020-08-01)
Article
Accés obertPerturbations in the ionosphere are of great interest not only for scientific research, but also for applications using transionospheric radiosignals (e.g. GNSS applications and HF communication), because the transmission ... -
Critical velocity in kink solutions of the sine-Gordon equation
(Universitat Politècnica de Catalunya, 2017-07)
Projecte Final de Màster Oficial
Accés obertThe goal of this work is to present a way to deduce the value of the critical velocity observed in soliton-like solutions of a perturbed version of the sine-Gordon equation. To do so, an ODE system is obtained from the ... -
Increased sensitivity to strong perturbations in a whole-brain model of LSD
(2021-04-15)
Article
Accés obertLysergic acid diethylamide (LSD) is a potent psychedelic drug, which has seen a revival in clinical and pharmacological research within recent years. Human neuroimaging studies have shown fundamental changes in brain-wide ... -
Perturbation analysis of a matrix differential equation ¿x=ABx
(UP4, Institute of Sciences, S.L., 2018)
Article
Accés restringit per política de l'editorialTwo complex matrix pairs (A,B) and (A',B') are contragrediently equivalent if there are nonsingular S and R such that (A',B')=(S-1AR,R-1BS). M.I. García-Planas and V.V. Sergeichuk (1999) constructed a miniversal deformation ... -
Perturbation analysis of simple eigenvalues of singular linear systems
(2013)
Text en actes de congrés
Accés obertIn this work a study of the behavior of a simple eigenvalue of singular linear system family E ( p )_ x = A ( p ) x + B ( p ) u , y = C ( p ) x smoothly dependent on a vector of real parameters p = ... -
Using in silico perturbational approach to identify critical areas in schizophrenia
(2023-06-15)
Article
Accés restringit per política de l'editorialSchizophrenia is a debilitating neuropsychiatric disorder whose underlying correlates remain unclear despite decades of neuroimaging investigation. One contentious topic concerns the role of global signal (GS) fluctuations ...
