Two exciting talks about fish-killing microalgae and their toxins.
Professor Sif Ríkhar?sdóttir and professor Haki Antonsson
Emil Aas Stoltenberg is assistant professor at BI Norwegian Business School, and associate professor (20%) at the University of Oslo (UiO). He holds a PhD in statistics from UiO (2020). From the first of June this year, he will be full-time at UiO.
Chebyshev varieties are algebraic varieties parametrized by Chebyshev polynomials or their multivariate generalizations. We determine the dimension, degree, singular locus and defining equations of these varieties. We explain how they play the role of toric varieties in sparse polynomial root finding, when monomials are replaced by Chebyshev polynomials. We present numerical root finding algorithms that exploit our results. Joint work with Za?neb Bel-Afia and Chiara Meroni.
The amplituhedron is a semi-algebraic set given as the image of the positive Grassmannian under a linear map subject to a choice of additional parameters. We define the Infinituhedron as the limit of amplituhedra by sending one of the parameters to infinity. We derive its algebraic boundary in terms of Chow varieties and explain its geometric interpretation from the point of view of Positive Geometry in terms of secants of the rational normal curve. This discussion shows that the Infinituhedron is a positive geometry with a unique differential form. Joint work with Rainer Sinn.
In this final seminar, J?rgen Finstad will present the draft of his PhD thesis titled “Exploring multi-sector dynamics of lumpy decarbonization technologies: The case of Carbon Capture in Norway”.
Helene Kn?velsrud, Associate Professor in the Division of Biochemistry at UiO, will present her work on "When should you stop eating yourself? Or how is autophagy terminated?"
Clara Bertinelli Salucci is a Postdoctoral Fellow at the Department of Mathematics, affiliated with the PLUMBIN' (Physics Learning Using Machines and Bayesian INference) project at the University of Oslo. She completed her PhD in Statistics and Machine Learning at the University of Oslo in April 2024, where she developed statistical and machine learning methods for diagnostics and prognostics of lithium-ion batteries for maritime applications. Currently, she is investigating the role of likelihood ratio test statistics for hypotheses tests in experimental and theoretical particle physics, focusing on deviations from Wilks' theorem in the search for new particles. Her postdoctoral research combines her expertise in statistics with her background in high-energy physics.
Department seminar. Kjetil Storesletten is a Professor of Economics at the University of Minnesota and an Adjunct Professor at the Department of Economics, University of Oslo. He will present the paper "Tax and Transfer Progressivity at the U.S. State Level" (joint with Johannes Fleck, Jonathan Heathcote, and Gianluca Violante).
Atmospheric clouds are complex three-phase systems containing ice crystals, supercooled liquid droplets, and water vapor. They are responsible for rain/snow formation and play a primary role in the planet’s radiative energy budget and the water cycle. In this talk, after describing the peculiar thermodynamics problems of water below 0 °C and the relative open scientific questions, I will present our first results on the role of turbulence in the condensation/evaporation processes in mixed-phase clouds where ice crystals grow at the expense of liquid droplets.
Deniz Malaymar Buts fra Bo?azi?i University i Tyrkia presenterer sitt forskningsprosjekt om barn og idealisert barndom i Tyrkia etter 1923, med utgangspunkt i barneblad og oversettelser
It is time for our monthly "mingle" meeting. Students and employees at the institute will meet up in the lobby.
Chantale Tippett is a PhD candidate at the TIK Centre for Technology, Innovation and Culture. This seminar marks her midway evaluation.
Department seminar. Gunnar S. Eskeland is a Professor of Resource and Environmental Economics, NHH Norwegian School of Economics. He will present the paper "Moral cartels: fossil owners in a climate treaty."
The invited speaker is Ian Mills, John Black Professor of Prostate Cancer at the University of Oxford and NCMM group leader alumni. The title of his talk is: "Reflections on prostate cancer research".
Lecture by Ernils Larsson, postdoctoral research fellow at the Centre for Multidisciplinary Research on Religion and Society.
Archaeological Friday seminar with Lavinia de Ferri from the Museum of Cultural History, University of Oslo.
The African Anthropology seminar series features Anselmo Matusse, researcher at the Department of Anthropology, University of Cape Town.
Jade Sandstedt (Volda University College / University of Troms?) and Maki Kubota (University of Bergen / University of Minho) will present their study on the neurophysiological and behavioral effects of exposure to low-level sociolinguistic variation on sentence processing.
In this final seminar, Lisa Scordato will present the draft of her PhD thesis titled “Paradoxes in crisis management: a study of public sector capabilities for addressing societal crises and disasters”.
Recent experiments have shown that epithelial monolayers can behave as self-propelled solid elastic membranes, and that global directed motion (polar order) emerges through the hierarchical annihilation of contractile elastic vortices and their anti-vortices[1]. Polar ordering dynamics in fluid cell layers is often modelled by neighbour alignment (Vicsek or Vicsek like models), another model is collective flow-alignment (move in the direction of flow). Here I will discuss the differences and similarities of these two mechanisms in solids. Both can give rise to interacting elastic vortices , but one model is essentially linear, while the other is non-linear and exhibit a rich dynamics which likely is relevant to many types of biological cell layers in the solid state.
