Talk on Friday Jul 28, 2023 at 12:00 Place: IFISC Seminar Room Title: An Introduction to Higher-Order Interactions for Social Systems and Epidemic Modeling Speaker: Beatriz Arregui García, IFISC (CSIC-UIB) Abstract: Network science is a fundamental tool for representing, understanding and analyzing an ever increasing variety of systems. However, the majority of works so far consider and represent the interactions between network&nbsp; &nbsp; components as pairwise. It is known that this is not always the real case as interactions themselves can involve more than two nodes, having substantial consequences on the dynamical processes affecting the different systems. The aforementioned raises the need of a new language able to describe and take into account these so-called higher order interactions, as well as developing efficient methods for their detection since the vast majority of datasets, in particular those displaying social interactions, are formulated with dyadic interactions. During this talk we will first introduce some of the recent methods implemented to recover higher order interactions from empirical data. Then, we will describe characteristics of higher order systems in social dynamics and focus on the implications for epidemic processes.

Talk on Tuesday Jul 18, 2023 at 12:00 Place: IFISC Seminar Room Title: Dynamics of seagrass meadows with two species Speaker: Pablo Moreno-Spiegelberg, IFISC (CSIC-UIB) Abstract: <pre> We study the interaction between two different seagrass species from a macroscopic point of view. In this framework, the changes in the species&#39; density are described by a system of two coupled partial differential equations for the density of each species. These equations describe the clonal reproduction of the plants and are coupled by the mortality term to describe interactions between different species. The interspecific interaction has been considered local and nonlinear, allowing low-density facilitation and large-density saturation. The proposed model has shown several scenarios such as mixed and monospecies homogeneous solutions, traveling waves, and spatio-temporal turbulence. Furthermore, the transition between these different solutions depends on abiotic factors, such as temperature increase. The transition between scenarios can, therefore, be used as an indicator of the degradation of the ecosystem. In particular, some behaviors indicate the approach to a tipping point, linked with a sudden and irreversible loss of the meadow. </pre> [1] <a class="moz-txt-link-freetext" href="https://arxiv.org/abs/2304.09693">https://arxiv.org/abs/… Zoom link: https://zoom.us/j/98286706234?pwd=bm1JUFVYcTJkaVl1VU55L0FiWDRIUT09 Url event:https://ifisc.uib-csic.es/en/events/seminars/dynamics-of-seagrass-meadows-with-two-species/

Talk on Thursday Jul 13, 2023 at 12:00 Place: IFISC Seminar Room Title: Harnessing ordered chaotic systems for quantum reservoir computing Speaker: Guillem Llodrà Bisellach, IFISC Abstract: Quantum reservoir computing (QRC) exploits the dynamical properties of quantum systems for machine learning tasks. We show that optimal performance in QRC can be achieved without resorting to disordered systems. Typically, QRC uses dynamical systems with all-to-all topology and random coupling to avoid redundancies. However, our work explores the emergence of a chaotic phase resulting from the competition between coupling and interaction terms in the one-dimensional Bose-Hubbard model with homogeneous coupling. Our results challenge established design principles and suggest simpler and more efficient implementations of QRC. &nbsp; Presential in the seminar room, and Zoom stream at&nbsp; zoom.us/j/98286706234?pwd=bm1JUFVYcTJkaVl1VU55L0FiWDRIUT09 Url event:https://ifisc.uib-csic.es/en/events/seminars/harnessing-ordered-chaotic-systems-for-quantum-res/
