      In the brain, spiking patterns live in a high-dimensional space of neurons and time. Thus, determining the intrinsic structure of this space presents a theoretical and experimental challenge. To address this challenge, we ...
    • 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 ...
    • Hyperactivation of monocytes and macrophages in MCI patients contributes to the progression of Alzheimer's disease
