Tankesmien Agenda og Senter for Utvikling og Milj? (SUM) inviterer til boklansering og paneldiskusjon om boka ?Do Gooders at the End of Aid. Scandinavian Humanitarianism in the 21st Century?.

China¡¯s rise to superpower status is the most important geopolitical change of our time. On November 3^rd we are excited to host two international experts on this topic, Elizabeth Economy and Shaun Breslin, in discussion with China correspondent for the New York Times, Amy Qin. 

Cards are drawn, one at a time, with replacement, from a deck of n cards. I study the total time W_n needed until we have seen all n cards, via different perspectives, along with a Gumbel limiting distribution. Various non-trivial identities, involving different perspectives for moments and Laplace transformations, are found as corollaries. These findings are also used to estimate the number of different cards,if uknown. If I needed to sample 133 words from a document, before I had 50 different words, what is the vocabulary size for the document? How many words did Shakespeare know (including those he never used in his writing)? 

An Abels T?rn podcast about some of these themes, which attracted a fair amount of inspired comments and guesses from the public (specifically, finding the mean of W_n above, for the case of n = 52 cards), can be found on the Abels T?rn website, July 2021, as a conversation with Torkild Jemterud, Jo R?islien, and myself.

Does climate panic cost us billions of dollars, harm the poor, and slow down transition to a better world?Arne N?ss seminars, Wigestrand Forlag and Norwegian Business School (BI) invite to a book debate with Bj?rn Lomborg, Bj?rn H. Samset and Atle Midttun. 

The Centre for Gender Research and the FRONT project are hosting the first event in the seminar series Gender Inequality and Precarity in Academia in the European Context. In this webinar, Sevil S¨¹mer will discuss the concept of gendered academic citizenship, focusing particularly on problems experienced by early-career academics, or ¡°transitional¡± academic citizens.

The PDE seminars for the Autumn of 2021 will be held every Tuesday from 10:15¨C12:00

Professor Dan Crisan, Imperial College London, author of several books on filtering is now holding an intensive course.

Abstract: Mixed-dimensional partial differential equations (PDEs) are equations coupling unknown fields defined over domains of differing topological dimensions. Such mixed-dimensional PDEs naturally arise in a wide range of fields including geology, biomedicine, and fracture mechanics. We introduce an automated framework dedicated to mixed-dimensional problems as part of the FEniCS library. This talk gives an overview of the abstractions and algorithms involved. The introduced tools will be illustrated by concrete examples of applications in biomedicine (see below for more detailed context).

This talk is part of the Mechanics Lunch Seminar series. Bring-your-own-lunch and lots of questions.

I anledning professor Anne Moens og f?rsteamanuensis Hilde W?iens 60©\?rsdag arrangerer avdeling for sykepleievitenskap jubileumsseminar fredag, den 22.oktober.

The talk is elementary and discusses empirical modelling of single variables with insurance losses as example. There are in such cases little or no theory to go on, and the amount of data is many situation quite scarce. Why do we so often limit ourselves to fit two-parameter families? It will be suggested that it may be a good idea to work with more flexible models with three or four parameters and that this may provide a nice framework for automating the entire procedure for the computer to work alone. Sure, with little data the parameters may be unstably estimated, but that may not apply equally to the distributions they define. Many-parameter families suitable for insurance losses will be reviewed with some simple asymptotics in an example allowing this and with Monte Carlo to throw light on the issue in other cases.

Welcome to this seminar, where Danica Kragic, Professor at the School of Computer Science and Communication at the Royal Institute of Technology, KTH, will talk about human action modelling and human-robot collaboration.

NCMM Associate Investigators, Magnus Aronsen, Associate Professor and Head of the Experimental Cardiology Group at the Institute of Basic Medical Sciences, UiO, and Alicia Llorente, Senior Scientist at the Institute for Cancer Research, Oslo University Hospital, will present their research as part of the NCMM Tuesday seminar series.

In this talk I will discuss the variational form of Bayes theorem by Zellner (1988). This result is the rationale behind the variational (approximate) inference scheme, although it is not always that clear in modern presentations. I will discuss two applications of this results. First, I will show how to do a low-rank mean correction within the INLA framework (with amazing results), which is essential for the next generation of the R-INLA software currently in development. In the second one, I will introduce the Bayesian   learning rule, which unify many machine-learning algorithms from fields such as optimization, deep learning, and graphical models. This includes classical algorithms such as ridge regression, Newton's method, and Kalman filter, as well as modern deep-learning algorithms such as stochastic-gradient descent, RMSprop, and Dropout.

The first part of the talk is based on our recent research at KAUST, while the second part is based upon \texttt{arxiv.org/abs/2107.04562} with Dr. Mohammad Emtiyaz Khan, RIKEN Center for AI Project, Tokyo.

Abstract: The concept of symmetry breaking is well-known in physics, for instance in condensed matter, where it results from interactions in a many-body system ¡ª e.g., phase transition in a spin system. Yet, as physicists, we tend not to think of the patterned structures seen in living, many-body systems in terms of broken symmetries. Whether it is the spacing of knuckles on our hand, the collective alignment of hairs on an insect wing, or more globally the transformation of a homogeneous, isotropic embryo into a developed organism, symmetry breaking abounds in biology. What new insights can a physicist bring to understand the origin of these complex phenomena? (Click title to read full abstract below...)

International Webinar on Chinese Multilateralism and its Impact on Environmental and Democratic Governance in Africa and Latin America

Abstract: Elimination of substances from the brain is believed to occur by a combination of convection and diffusion. In previous work, transport along perivascular spaces around blood vessels have been explicitly meshed and modeled, and also 1D-3D models have been used to model the interaction between blood and brain tissue. A problem with both these approaches is that it requires spatial information of all blood vessels within the brain and in addition may result in a computationally expensive system to solve. In this talk, I will introduce a homogenized model of transport in the brain, also taking into account transfer between different compartments (like blood and brain tissue) within the brain. Fluid flow in and between compartments are modeled with the mulitple-porosity elasticity theory (MPET), while transport within and between compartments are modeled with convection-diffusion equations. I will further show preliminary results from our model and compare with experimental data obtained in a glioma (brain tumor) patient, where transport between blood and brain is typically altered.

Vestlig statsfeminisme blir ofte beskyldt for ? ha et snevert fokus p? hvithet, cishet, heteroseksualitet og friskhet. I dette arrangementet ?nsker vi ? belyse at de fleste av oss befinner oss i en flytende kompleksitet som varer livet ut, der kroppene v?re kan forandre seg og identitetskategorier vi kan ta for gitt, endres. Dette medf?rer livslang l?ring b?de om oss selv, og i samspill med andre mennesker og med v?re omgivelser.
