#### Computational predictive modeling of integrated cerebral metabolism, electrophysiology and hemodynamics

(2019-02-12)

Understanding the energetic requirement of brain cells during resting state and during high neuronal activity is a very active research area where mathematical models have contributed significantly by providing a context ...

#### Anticipation via canards in excitable systems

(Chaos: An Interdisciplinary Journal of Nonlinear Science, 2019-01-14)

Neurons can anticipate incoming signals by exploiting a physiological mechanism that is not well understood. This article offers a novel explanation on how a receiver neuron can predict the sender’s dynamics in a ...

#### Is minimising the convergence rate the best choice for efficient Optimized Schwarz preconditioning in heterogeneous coupling? The Stokes-Darcy case

(2019)

Optimized Schwarz Methods (OSM) are domain decomposition techniques based on Robin-type interface condition that have became increasingly popular in the last two decades. Ensuring convergence also on non-overlapping ...

#### Atomistic Insight into Ion Transport and Conductivity in Ga/Al-Substituted Li$_7$La$_3$Zr$_2$O$_{12}$ Solid Electrolytes

(ACS Applied Materials & Interfaces, 2018-12-12)

Garnet-structured Li$_{7}$La$_{3}$Zr$_{2}$O$_{12}$ is a promising solid electrolyte for next-generation solid-state Li batteries. However, sufficiently fast Li-ion mobility required for battery applications only emerges ...

#### Pro-C congruence properties for groups of rooted tree automorphisms

(Archiv der Mathematik, 2018-11-21)

We propose a generalisation of the congruence subgroup problem for groups acting on rooted trees.
Instead of only comparing the profinite completion to that given by level stabilizers, we also compare pro-$\mathcal{C}$ ...

#### Multi-GGS groups have the congruence subgroup property

(Proceedings of the Edinburgh Mathematical Society, 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 ...

#### Optimized Schwarz Methods in the Stokes-Darcy Coupling

(IMA J. Num. Analysis 38 (4), 2018-10-16)

This article studies optimized Schwarz methods for the Stokes–Darcy problem. Robin transmission conditions are introduced, and the coupled problem is reduced to a suitable interface system that can be solved using Krylov ...

#### A least-squares implicit RBF-FD closest point method and applications to PDEs on moving surfaces

(Journal of Computational Physics, 2018-10)

The closest point method (Ruuth and Merriman, J. Comput. Phys. 227(3):1943-1961, [2008]) is an embedding method developed to solve a variety of partial differential equations (PDEs) on smooth surfaces, using a closest point ...

#### No Time at the End of the Tunnel

(Communications Physics – Nature, 2018-08-21)

Modern atto-second experiments seek to provide an insight into a long standing question: “how much time does a tunnelling particle spend in the barrier?” Traditionally, quantum theory relates this duration to the delay ...

#### Qualitative analysis of kinetic-based models for tumor-immune system interaction

(Discrete and Continuous Dynamical Systems - Series B, 2018-08)

A mathematical model, based on a mesoscopic approach, describing the competition between tumor cells and immune system in terms of kinetic integro-differential equations is presented. Four interacting populations are ...
