2nd Meeting of the Spanish Chapter of the Complex Systems Society | CS3

She received BSc degree in Physics from the University of Buenos Aires, Argentina (1986), and PhD in Physics from the Brazilian Center for Physics Research (CBPF, 1993), having done part of her thesis at the University of Waterloo, Canada. Later she conducted postdoctoral research in nonlinear and statistical physics at CBPF and at the Biophysics Institute of the Federal University of Rio de Janeiro (UFRJ-IBCCF), where she was visiting professor from 1997 to 2001.

Title:
Interplay between adaptive awareness and epidemic spreading

Abstract:
The adoption of attitudes by the population to mitigate epidemic outbreaks, such as social isolation, hand washing, or the use of face masks, can be influenced by the perception of the epidemic scenario.
This perception is shaped by local and global information, and can be distorted by misinformation. Particularly, we study the impact of local and global information about the epidemic status in a susceptible–infected–recovered (SIR) dynamic that evolves in complex networks, in which the epidemiological perception of the environment can influence the behavior of susceptible individuals towards protective measures. We observe that local awareness significantly raises the epidemic threshold, delays the peak of prevalence, and reduces the outbreak size, however these effects are reduced by network heterogeneity. These results may have implications for mitigation strategies. On the other hand, the agent-based simulations reveal aspects not captured by the heterogeneous mean-field theory, which can represent a mathematical challenge to improve the theory.

Bullying is a very serious problem that previous literature has shown affects a large fraction of students in compulsory schooling. We use a social networks approach to study victimization and perpetration of bullying at schools. We use a large database from high school students in Spain and collect data from their friendships, as well as individual characteristics. We show that their social network characteristics are strongly predictive of both victimization and perpetration of bullying.

I am a Full Professor distinguished with two consecutive ICREA Academia Awards (2016, 2021) at (UPC), member of CRM and IMTECH. I have been recently distinguished with the François Deruyts Prize by the Royal Academy of Belgium and with a Bessel Prize by the Alexander Von Humboldt foundation. I am the 2023 London Mathematical Society Hardy lecturer as such I have enjoyed lecturing a 9 stop-tour in the summer of 2023 which has been quite a unique experience. The picture above was taken in the middle of the tour at the University of Loughborough.

I am the director of the Laboratory of Geometry and Dynamical Systems and the group leader of GEOMVAP (Geometry of Varieties and Applications). I have been the happy advisor of 12 PhD students.

My research deals with several aspects of Differential Geometry, Mathematical Physics and Dynamical Systems such as Symplectic and Poisson Geometry, Hamiltonian Dynamics, Group actions and Geometric Quantization. Almost a decade ago I started the investigation of several facets of b-Poisson manifolds (also known as log-symplectic manifolds). These structures appear naturally in physical problems on manifolds with boundary and in Celestial mechanics such as the 3-body problem (and on its restricted versions) after regularization transformations. I recently got interested in Fluid Dynamics and the study of their complexity (computational, topological, logical, dynamical) by looking through a contact mirror unveiled two decades ago by Etnyre and Ghrist. I am working in extending Floer homology to a class of Poisson manifolds including b-Poisson manifolds and the classical Weinstein conjecture in this set-up. My motivation comes from the search of periodic orbits on regularized problems in Celestial Mechanics (more information here).

Title: Scaling of brain activity and optimal functionality: from real neurons to artificial intelligence.

Speaker: Miguel Ángel Muñoz Universidad de Granada

Abstract:
I will review recent advances in data-driven analyses of brain activity, which complemented by theoretical studies such as renormalization-group techniques, allow us to shed light on the dynamical regime in which neural activity operates across brain regions. We leverage these insights to design and scrutinize artificial neural networks with recurrent interactions. We find that both biological and artificial networks achieve optimal performance when balanced to operate close to the edge of instability.

Title:
From Complexity to Simplicity: the Rise and Fall of Innovations

Abstract:
When examining the history of technology, it becomes evident that not all inventions are defined equal. Only a chosen few have the potential to start new branches of development, significantly impact human life, and become pivotal turning points in history. The question arises: Is technological change a continuous and gradual process, or does it occur in sudden leaps and bounds? In this talk, we will explore the rise and fall of technological innovations by examining the relationship between diversity, information redundancy, open-endedness, and the role of cumulative cultural evolution (CCE) in driving technological change. Through the analysis of the evolution of information technology (IT), we will gain insights into the quantitative and theoretical aspects of cultural evolution.
