IFISC Colloquium on Wednesday Jun 29, 2022 at 14:30 Place: IFISC Seminar Room Title: Resilience and transitions of global complex urban systems Speaker: Céline Rozenblat, University of Lausanne (UNIL), Switzerland Abstract: In the context of the climate change and energetic and political crises, new tendencies in the long/medium term evolution of urban systems, together with new data and methods, require that existing theoretical assumptions and conceptualizations be challenged as global urban hierarchies are reconfigured. The connection between urban systems at different levels of organization becomes more and more relevant for understanding urban systems and their transitions. But the current inter-urban perspective is not sufficient to encompass these dynamics. The evolution of power distributions inside and between cities reshapes the world organization of central/peripheral cities and the complexity of the global urban system. Actors as multinational firms, or high-level innovation centers, participate actively in these reconfigurations that concentrate wealth, control, innovation, and attractiveness in a few cities. In the complexity of this multi-level system, how is regionalization of the world reshaping in a multipolar urban world? How does the multi-level perspective highlight some resilience properties? The methodologies derived from complex systems sciences bring new forms of intelligibility to worldwide urban transitions.

Talk on Tuesday Jun 28, 2022 at 12:00 Place: Zoom Seminar Title: Convex optimization for non-equilibrium steady states on a hybrid quantum processor Speaker: Jonathan W. Z. Lau, CQT Singapur Abstract: Topic: MdMQuantumMeeting Join Zoom Meeting: <a href="https://uibuniversitat.zoom.us/j/94232467915" target="_blank">https://uibuniversitat.zoom.us/j/94232467915</a> Abstract: Finding the transient and steady state properties of open quantum systems is a central problem in various fields of quantum technologies. Here, we present a quantum-assisted algorithm to determine the steady states of open system dynamics. By reformulating the problem of finding the fixed point of Lindblad dynamics as a feasibility semi-definite program, we bypass several well known issues with variational quantum approaches to solving for steady states. We demonstrate that our hybrid approach allows us to estimate the steady states of higher dimensional open quantum systems and discuss how our method can find multiple steady states for systems with symmetries.

Talk on Tuesday Jun 28, 2022 at 14:00 Place: IFISC Seminar Room Title: Identifiability and prediction in ecological interaction network models Speaker: Leonardo Aguirre, Eawag, ETH-Domain Abstract: Abstract:&nbsp; Many processes in ecology are fundamentally driven by known interactions between individuals. Meanwhile the pressing questions, such as species extinction, are naturally posed at the system level. Mapping a microscopic agent-based description to a mesoscopic aggregate model is of course a highly non-trivial matter and generally introduces noise as a result of observing only certain selected degrees of freedom. One approach is to frame the mesoscopic dynamics as a continuous-time Markov chain whose states are accounts of taxa abundances and whose transitions are interaction events. Such &#39;Markovian interaction networks&#39; have previously risen to fame in systems biology as biochemical reaction networks and have likewise been a subject of theoretical ecology for over half a century. However they are not as widely adopted in experimental ecology studies as their infinite-population ODE counterparts. After reviewing the basics of Markovian interaction networks I wil l focus on their prediction theory which involves stochastic filtering and give a glimpse into an ongoing software project of developing a general solution to integrate Markovian interaction networks into experimental design protocols and facilitate the discourse between theorists and experimentalists around that subject. zoom link:&nbsp;https://us06web.zoom.us/j/85744990492?pwd=U3l3YUh6ZmNVUjNVOVV4dldxdHdVQT09 Url event:https://ifisc.uib-csic.es/en/events/seminars/identifiability-and-prediction-in-ecological-inter/

IFISC Seminar on Wednesday Jun 22, 2022 at 14:30 Place: Zoom Seminar Title: The role of non-conservative interactions in non-equilibrium stochastic systems Speaker: Sarah Loos, DAMTP Cambridge, and ICTP Trieste Abstract: The world surrounding us, including all living matter and various artificial complex systems, mostly operates far from thermal equilibrium. Recently, lively effort is dedicated in the fields of stochastic thermodynamics and statistical physics to unravel the fundamental principles that govern the individual and collective dynamics of such nonequilibrium systems, like the swarming of fish or flocking of birds. However, so far, little attention has been paid to the implications of non-conservative interactions, like time-delayed or non-reciprocal interactions. Such interactions emerge commonly in biological, chemical and feedback systems, and are widespread in engineering and machine learning. In this talk, I will use simple models to discuss technical challenges and unexpected physical phenomena induced by non-reciprocity [1] and time delay [2].

Hi! Sadly, there are some bad news that you are about to hear. About few months ago I have gained a full access to all devices used by you for internet browsing. Shortly after, I started recording all internet activities done by you. Below is the sequence of events of how that happened: Earlier I purchased from hackers a unique access to diversified email accounts (at the moment, it is really easy to do using internet). As you can see, I managed to log in to your email account without breaking a sweat: (semfis(a)ifisc.uib-csic.es) Within one week afterwards, I installed a Trojan virus in your Operating Systems available on all devices that you utilize for logging in your email. To be frank, it was somewhat a very easy task (since you were kind enough to open some of links provided in your inbox emails). I know, you may be thinking now that I'm a genius. With help of that useful software, I am now able to gain access to all the controllers located in your devices (e.g., video camera, keyboard, microphone and others). As result, managed to download all your photos, personal data, history of web browsing and other info to my servers without any problems. Moreover, I now have access to all accounts in your messengers, social networks, emails, contacts list, chat history - you name it. My Trojan virus continues refreshing its signatures in a non-stop manner (because it is operated by driver), hence it remains undetected by any antivirus software installed in your PC or device. So, I guess now you finally understand the reason why I could never be caught until this very letter... During the process of your personal info compilation, I could not help but notice that you are a huge admirer and regular guest of websites with adult content. You endure a lot of pleasure while checking out porn websites, watching nasty porn movies and reaching breathtaking orgasms. Let me be frank with you, it was really hard to resist from recording some of those naughty solo scenes with you in main role and compiling them in special videos that expose your masturbation sessions, which end with you cumming. In case if you still have doubts, all I need is to click my mouse and all those nasty videos with you will be shared to friends, colleagues, and relatives of yours. Moreover, nothing stops me from uploading all that hot content online, so all public can watch it too. I sincerely hope, you would really not prefer that to happen, keeping in mind all the dirty things you like to watch, (you certainly know what I mean) it will completely ruin your reputation. However, don't worry, there is still a way to resolve this: You need to carry out a $1490 USD transfer to my wallet (equivalent amount in bitcoins depending on exchange rate at the moment of funds transfer), hence upon receiving the transaction, I will proceed with deleting all the filthy videos with you in main role. Afterwards, we can forget about this unpleasant accident. Furthermore, I guarantee that all the malicious software will also be erased from your devices and accounts. Mark my words, I never lie. That is a great bargain with a low price, I assure you, because I have spent a lot of effort while recording and tracking down all your activities and dirty deeds during a long period of time. In case if you have no idea how to buy and transfer bitcoins - feel free to check the related info on the internet. Here is my bitcoin wallet for your reference: 1K8g3n8Z9t265pMYuhpKc8jfmPS6cY7Qcr From now on, you have only 48 hours and countdown has started once you opened this very email (in other words, 2 days). The following list contains things you should definitely abstain from doing or even attempting: > Abstain from trying to reply this email (since the email is generated inside your inbox alongside with return address). > Abstain from trying to call or report to police or any other security services. In addition, it's a bad idea if you want to share it with your friends, hoping they would help. If I happen to find out (knowing my awesome skills, it can be done effortlessly, because I have all your devices and accounts under my control and unceasing observation) - kinky videos of yours will be share to public the same day. > Abstain from trying to look for me - that would not lead anywhere either. Cryptocurrency transactions are absolutely anonymous and cannot be tracked. > Abstain from reinstalling your OS on devices or throwing them away. That would not solve the problem as well, since all your personal videos are already uploaded and stored at remote servers. Things you may be confused about: > That your funds transfer won't be delivered to me. Chill, I can track down any transactions right away, so upon funds transfer I will receive a notification as well, since I still control your devices (my trojan virus has ability of controlling all processes remotely, just like TeamViewer). > That I am going to share your dirty videos after receiving money transfer from you. Here you need to trust me, because there is absolutely no point to still bother you after receiving money. Moreover, if I really wanted all those videos would be available to public long time ago! I believe we can still handle this situation on fair terms! Here is my last advice to you... in future you better ensure you stay away from this kind of situations! My advice - don't forget to regularly update your passwords to feel completely secure.
