Mathematics students learn a powerful technique for proving theorems about an arbitrary natural number: the principle of mathematical induction. This talk introduces a closely related proof technique called "path induction," which can be thought of as an expression of Leibniz's "indiscernibility of identicals": if x and y are identified, then th...

In this presentation, I will revisit current mechanistic views about the propagation of cortical spreading depressions using electrophysiological data from rats obtained by means of high-resolution microelectrode arrays (MEA). Firstly, I will discuss the existence of facilitation/adaptation mechanisms in the CSD propagation, potentially related ...

Motivated by practical applications, chiefly clinical trials, we study the regret achievable for stochastic multi-armed bandits under the constraint that the employed policy must split trials into a small number of batches. Our results show that a very small number of batches gives already close to minimax optimal regret bounds and we also evalu...

Recent advances in computational geometry and computational topology have made it possible to compute topological invariants of sets and functions from sample points. These types of data summaries provide new tools for preprocessing, summarizing and visualizing complex and even high dimensional data. As a result, the number and the variety of ap...

Dynamical systems with a coupled cell network structure arise in applications that range from statistical mechanics and electrical circuits to neural networks, systems biology, power grids and the world wide web. A network structure can have a strong impact on the behaviour of a dynamical system. For example, it has been observed that networks c...

Traditional fMRI data analyses are mainly focused on discoveringbrain activation patterns using standard GLM technique that selects voxels based on their individual correlations with stimuli.However, such mass-univariate approach completely ignores voxel interactions that are often essential for understanding brain functions,and can be better ca...

For animals and machines alike, maintaining balance during flight is acrucial and demanding task. The need for airplane flight stability led toa schism between aviators who sought built-in, or passive, stability andthose who emphasized the need for active controls. How has this tensionplayed out for the first flyers, the insects? Our group combi...

Functional connectivity in neuroscience is considered as one of the main features of the neural code. It is nowadays possible to obtain the spike activities of tens to hundreds of neurons simultaneously and the issue is then to infer the functional connectivity thanks to those complex data. To deal with this problem, we consider estimation of sp...
