IFISC Seminar on Wednesday Feb 08, 2023 at 14:30 Place: IFISC Seminar Room Title: The faster, the better: How to accelerate photonic computing to meet the requirements of optical transmission systems Speaker: Irene Estébanez, IFISC Abstract: Photonic reservoir computing is an information processing technique that uses the dynamical response of semiconductor lasers to injected data to perform complex computations. Depending on the task, this approach might offer several benefits over traditional electronic computing, including faster processing speed, greater energy efficiency, and improved performance. Here, we will focus on the application of photonic reservoir computing in the real-world task of optical signal recovery and time series prediction. Based on numerical and experimental results, we demonstrate how bandwidth enhancement can be leveraged to further increase processing speed.

Talk on Thursday Feb 09, 2023 at 12:00 Place: IFISC Seminar Room Title: Information ecosystems: an ecological approach to computational social science Speaker: Violeta Calleja, IFISC (CSIC-UIB) Abstract: Abstract:&nbsp; Understanding human interactions in online communications is of paramount importance for our society. Alarming phenomena such as the spreading of fake news or the formation of echo chambers can emerge in unhealthy communication environments and, ultimately, undermine the democratic discourse. In this context, among many,&nbsp; two issues challenge the health of our information ecosystems: first, being able to identify their universal characteristics; and second, unveiling the individual drivers that give rise to collective attention. Here, following a recently proposed analogy between natural and information ecosystems, we explore these two challenges. We will present universal patterns that arise in very different discussions of online social networks,&nbsp; and we will continue explaining how our communication dynamics are shaped by the competition for attention in these online social networks and the strategies adopted by the users to maximize their visibility.

Talk on Friday Feb 03, 2023 at 15:00 Place: IFISC Seminar Room Title: Interacting particle systems with mobility and demographic dynamics as biological models Speaker: Alejandro Almodovar, IFISC Abstract: The behaviour of active matter has been intensively investigated in the last decades partly because of its many applications to living systems. In this work, we add stochastic birth-death dynamics to a system of particles with volume exclusion. This is a simple, but general biological ingredient which has not been studied in detail before. The number of particles in the system at long times depends on the birth and death rates, and on a parameter characterising the activity. We find liquid, solid and hexatic phases in the absence of activity. Which one of these phases is realised depends on the birth and death rates. When self-propulsion &nbsp;is considered, we also observe these phases depending on the activity. we will also analyse what happens when there are two types of particles of different sizes. We will study the conditions to find coexistence. Finally, we will show preliminary results when the rates of birth and death are modified by a voter-like interaction, I.e., the demographic rate of each particle depends on those on the surrounds.

Talk on Friday Feb 03, 2023 at 12:00 Place: IFISC Seminar Room Title: Spatial memory in rats under non-life-threatening conditions Speaker: Jorge Medina, IFISC Abstract: <pre> The Morris water navigation task, also known as the Morris water maze, is a commonly used behavioral procedure for studying spatial learning and memory in rodents. In this experiment, a rat is placed in a large circular pool and must find an invisible platform to escape the water. However, this situation puts the rats under high stress, which can be perceived as life-threatening by them. Our goal is to evaluate spatial memory formation in a setting closer to the rat&#39;s daily life (a circular arena in the ground) with a softer, more natural reward: switching off the lights when the target is found. Since rats prefer dark environments, it has the potential to motivate rats to complete the task, without causing too much anxiety. Specifically, we measure memory formation within a single day of experimentation (short-term memory) and between two consecutive days (long-term memory), and analyze how these results change when certain drugs are administered to the rats.</pre> Url event:https://ifisc.uib-csic.es/en/events/seminars/spatial-memory-in-rats-under-non-life-threatening/

Talk on Thursday Feb 02, 2023 at 15:00 Place: IFISC Seminar Room Title: Analysing multidimensional inequalities from housing and transport in Madrid Speaker: Jesús A. Moreno López, IFISC Abstract: <pre> The infrastructure of a city can influence inequality on multiple axes. In this work we aim to create a generalizable, open source methodology to analyse inequalities in transport accessibility which, paired with a thorough analysis of building energy efficiency, can lead us to pinpoint urban areas where both heating and transport needs lead to a high economical impact for many households. Real micro-data extracted from mobility questionnaires and cell phone data is used to compute and adjust a multi-agent transport simulation based on utility and cost functions for both travel and destination activities, which provides us with modes, times and fees for each transport demand. This mobility analysis performed on the whole street and public transport network of Madrid is paired with energy efficiency data of housing to give a multidimensional approach to inequality inherent to the spatial distribution and quality of infrastructure in Madrid. </pre> Url event:https://ifisc.uib-csic.es/en/events/seminars/analysing-multidimensional-inequalities-from-housi/

Talk on Thursday Feb 02, 2023 at 12:00 Place: IFISC Seminar Room Title: Balearic power grid stability in scenarios with large photovoltaic generation Speaker: María Martínez-Barbeito, IFISC (UIB-CSIC) Abstract: The first step in the decarbonization agenda of the Balearic Islands was to close down a coal fired power plant in December 2019. In the upcoming years, the following steps will be to integrate a higher share of solar photovoltaic generation. In this talk, I will analyze the frequency fluctuations and the overall grid stability in such scenarios. I will also analyze the role of the High Voltage Direct Current (HVDC) link with mainland Spain in the control requirements needed to ensure grid stability. https://uibuniversitat.zoom.us/j/94682807892 Url event:https://ifisc.uib-csic.es/en/events/seminars/balearic-power-grid-stability-in-scenarios-with-la/

IFISC Seminar on Wednesday Feb 01, 2023 at 14:30 Place: IFISC Seminar Room Title: Beyond simple dynamics: coevolutionary dynamics Speaker: Alessio Cardillo, UOC Abstract: Abstract: For years, simple models have been used successfully to describe a plethora of phenomena taking place in complex systems. For instance, models like the Kuramoto model or the Prisoner&#39;s Dilemma game have been used as paradigms to study the emergence of synchronization and cooperation in populations of elements interacting with each other. Despite the achievements of the reductionist approach, there is a whole set of problems/phenomena that cannot be tackled/understood in terms of a single (simple) type of dynamical process. For instance, the spontaneous adoption of vaccines cannot be fully understood if we model it as a mere response to a cost over benefit analysis. To address more complex phenomena, we need to move beyond simple dynamical processes by intertwining two (or more) of them together using a coevolutionary approach. In this talk, I will present some examples of coevolutionary dynamics models and show how the phenomenology observed combining two dynamical processes together is, quoting Anderson&#39;s famous motto,&nbsp;&quot;more than the sum of its parts&quot; which constitutes one of the hallmarks of complexity.
