      The conductance-based refractory density (CBRD) approach is a parsimonious mathematical-computational framework for modeling interact- ing populations of regular spiking neurons, which, however, has not been yet extended ...
    • Grigorchuk-Gupta-Sidki groups as a source for Beauvile surfaces 

      Sükran, G.; Uria-Albizuri, J. (2020-04-14)
      If $G$ is a Grigorchuk-Gupta-Sidki group defined over a $p$-adic tree, where p is an odd prime, we study the existence of Beauville surfaces associated to the quotients of $G$ by its level stabilizers $st_G(n)$. We prove ...

(2021-12-01)
      Background: Alzheimer’s disease (AD) is the most common neurodegenerative disease ultimately manifesting as clinical dementia. Despite considerable effort and ample experimental data, the role of neuroinflammation related ...
    • Inflection, Canards and Folded Singularities in Excitable Systems: Application to a 3D FitzHugh–Nagumo Model 

      Uria-Albizuri, J.; Desroches, M.Autoridad BCAM; Krupa, M.; Rodrigues, S.Autoridad BCAM (2020-09-07)
      Specific kinds of physical and biological systems exhibit complex Mixed-Mode Oscillations mediated by folded-singularity canards in the context of slow-fast models. The present manuscript revisits these systems, specifically ...
    • Metastable resting state brain dynamics 

      beim Graben, P.; Jimenez-Marin, A.; Diez, I.; Cortes, J.M.; Desroches, M.Autoridad BCAM; Rodrigues, S.Autoridad BCAM (2019-09-06)
      Metastability refers to the fact that the state of a dynamical system spends a large amount of time in a restricted region of its available phase space before a transition takes place, bringing the system into another state ...
    • Microbial production of advanced biofuels 

      Keasling, J.; Garcia Martin, H.; Lee, T; Mukhopadhyay, A.; Singer, S.; Sundstrom, E. (2021)

    • Multi-GGS groups have the congruence subgroup property 

      Garrido, A.; Uria-Albizuri, J. (2018-11-08)
      We generalize the result about the congruence subgroup property for GGS-groups to the family of multi-GGS-groups; that is, all multi-GGS-groups except the one defined by the constant vector have the congruence subgroup ...
