Two #postdoc jobs on infectious disease dynamics, one math modelling, one experimental with Roland Regoes and me at ETH Zurich. More info here: https://jobs.ethz.ch/job/view/JOPG_ethz_cFnH1vVUIrGOtR06hZ and https://jobs.ethz.ch/job/view/JOPG_ethz_7PJ2CQ0RJzQvkVMh1K.

At the Division of Statistics and Machine Learning, Department of Computer and Information Science, Linköping University, 21st-24th March 2023 we will be hosting a school concerning stochastic differential equations and the YUIMA R package (Simulation and Inference for SDEs and Other Stochastic Processes, https://cran.r-project.org/web/packages/yuima/index.html The lectures will be given by members of the YUIMA team. Below is a nearly final program of the school. The dates are fixed. A similar event took place in summer 2019: https://yuimaproject.com/yss2019/ Please feel free to spread information about the school around. If anyone would be interested in coming, they should e-mail me directly. The registration deadline is 28th February 2023. However, we might end registration early if the amount of interested participants exceeds our capacity. Students who choose to take the school as a course, can obtain 3credits for it. Examination will be through a hand-in assignment. Please let me know if you would be interested in this option. Tentative program, can be subject to change but dates 21 March-24 March fixed We assume the participants are familiar with R. Laboratory means that this session will contain short exercises (ca 15min) to be done by the participants on their own laptops. The YUIMA Conference sessions will be more advanced research oriented talks, everyone is welcome to attend. If you would have a related research topic to and would be interested in presenting, then please let me know. I will see what possibilities we would have. DAY 1 (Mar 21) 10:45-11:30 Introduction to stochastic calculus I (stochastic processes, Brownian motion, labo with R) 13:00-14:15 Introduction to stochastic calculus II (stochastic integral and SDE, labo with R) 14:25-14:50 What can we do with YUIMA? 15:00-16;00 Linkoping Statistics Seminar + YUIMA Conference DAY 2 (Mar 22) 09:00-10:15 Simulation of diffusion processes I (Euler-Maruyama approximation and introduction to YUIMA: yuima object, simulation, plot, Black-Scholes model, labo) 10:30-11:30 Simulation of diffusion processes II (simulation of various models for illustrations) 13:00-14:00 Laboratory (simulation with YUIMA) 14:15-15:30 Poisson process and Compound Poisson processes (introduction, simulation, laboratorory) 15:50-16:50 YUIMA Conference DAY 3 (Mar 23) 09:00-10:15 Inference for diffusion processes I (QMLE) 10:30-11:30 Inference for diffusion processes II (quasi-Bayes estimation) 13:00-14:45 Model selection for diffusion processes 15:00-16:00 YUIMA GUI 16:10-17:10 YUIMA Conference DAY 4 (Mar 24) 09:00-10:00 Levy processes and Levy driven SDE I (theoretical background and some examples) 10:30-11:30 Levy processes and Levy driven SDE II (simulation in YUIMA) 13:00-16:00 YUIMA Conference

Predicting personality, death, emigration, and other life-events from embeddings of registry data Sune Lehmann December 12 , 11:00 – 12:00 UTC+2 https://www.popnet.io/event/popnet-connects-with-sune-lehmann/ Over the past decade, machine learning has revolutionised computers’ ability to analyze text through flexible computational models. Beyond text, emerging transformer-based architectures have shown promise as tools to make sense of a range of multi-variate sequences from protein-structures to weather-forecasts due to their structural similarity to written language. Another type of process which has a strong structural similarity to language is human lives. From one perspective, lives are simply sequences of events: We are born, we visit the pediatrician, we start school, we move to a new location, we get married, and so on. Here, we use this similarity to adapt innovations from natural language processing to examine the evolution and predictability of human lives based on day-to-day event sequences.

Landau theory for the Mpemba effect through phase transitions Roi Holtzman & Oren Raz The Mpemba effect describes the situation in which a hot system cools faster than an identical copy that is initiated at a colder temperature. In many of the experimental observations of the effect, e.g. in water and clathrate hydrates, it is defined by the phase transition timing. However, none of the theoretical investigations so far considered the timing of the phase transition, and most of the abstract models used to explore the Mpemba effect do not have a phase transition. We use the phenomenological Landau theory for phase transitions to identify the second order phase transition time, and demonstrate with a concrete example that a Mpemba effect can exist in such models. https://www.nature.com/articles/s42005-022-01063-2
