Constructing fast solution schemes often involves deciding which errors are acceptable and which approximations can be made for the sake of computational efficiency. Herein, we consider a mixed formulation of Darcy flow in porous media and take the perspective that the physical law of mass conservation is significantly more important than the constitutive relationship, i.e. Darcy's law. From this point of view, we propose an inexact solution technique that nevertheless guarantees local mass conservation. The method is based on first solving the mass balance equation and then computing a solenoidal correction using the curl of a potential field. We extend the method to flows in fractured porous media and present numerical experiments that indicate the efficiency of the scheme.

Effects of early life environmental conditions on endocrine and cardiac physiology in Atlantic Salmon

How can Circle U. students, academics, and leaders collaborate on interdisciplinary education and find ways to prepare students for coping with wicked problems?

Fano manifolds are complex projective manifolds having positive first Chern class. The positivity condition on the first Chern class has far reaching geometric and arithmetic implications. For instance, Fano manifolds are covered by rational curves, and families of Fano manifolds over one dimensional bases always admit holomorphic sections. In recent years, there has been some effort towards defining suitable higher analogues of the Fano condition. Higher Fano manifolds are expected to enjoy stronger versions of several of the nice properties of Fano manifolds.

In this talk, I will discuss higher Fano manifolds which are defined in terms of positivity of higher Chern characters. After a brief survey of what is currently known, I will present recent joint work with Carolina Araujo, Roya Beheshti, Kelly Jabbusch, Svetlana Makarova, Enrica Mazzon and Nivedita Viswanathan, regarding toric higher Fano manifolds. I will explain a strategy towards proving that projective spaces are the only higher Fano manifolds among smooth projective toric varieties.

Title: Estimating climate sensitivity in the presence of tipping points

Speaker: Peter Ashwin, University of Exeter

Welcome to our weekly lunch seminar held in the dScience lounge area! This event is open to PhD candidates and postdocs.

Comparing qPCR and eDNA-metabarcoding for detection of elusive lampreys

Biotechnology innovations seem to emerge at lightning speed. At the same time, countless grand societal challenges demand resources and cultural shifts. What does 21st century innovation look like in the context of ongoing crises such as climate change, as well as short-term shocks like covid, macroeconomic constriction, and war in Europe? In such times, big companies shrink their ambitions; what about emerging ventures?

Meet up at Physics at the Library for a lecture about how network science is an indispensable tool from physics to medicine by Professor Albert-László Barabási, Northeastern University.

Skal vi finne gode løsninger på klimaendringene må vi forstå hvordan naturen henger sammen. Men, hva om naturen spiller oss et puss og avdekker nye trusler i det vi er i ferd med å knekke koden?

Solving Phylogenetic Relationships Within the Rove Beetle Genus /Aleochara/ (Coleoptera: Staphylinidae) by Utilizing a Novel Approach based on High Throughput Sequencing

For millennia, origami and kirigami artists have used folds and cuts to create beautiful shapes from a simple sheet of paper. I will describe our recent scientific attempts to catch up with these remarkably imaginative arts phrased as inverse problems in physical geometry that aim to control the shape and rigidity of a thin surface. Using discrete operations that vary the number, size, orientation and coordination of folds and cuts, I will show how to create piecewise isometric kirigami and origami tessellations and control their local and global morphology and mechanical response, mixing experimental, computational and theoretical approaches.

Late Lunch Talk by George Pacheco

We are happy to invite to a 3 day-workshop on CNES (the French National Centre for Space Studies) tools, from 21st of March to 23rd of March. The workshop is open to all interested!  

The event is free of charge for members of the CENSSS Consortia, students and representatives from Academia.

For industry partners outside of CENSSS there will be a small fee to cover the expenses of food. 

The workshop will take place at UiO at Gunnar Randers vei 19, 2007 Kjeller.

Coffee and simple lunches will be served.

Hylleraas seminar, hosted in Tromsø

Enriched enumerative geometry is a new area in which we take results in enumerative geometry over the complex numbers and refine them to give results over any base field. The "refinements" in question recover the classical results over algebraically closed fields but may also include arithmetic information about the base field. In this talk, I'll give an overview of a proof of an enriched refinement of the Yau-Zaslow formula for counting rational curves on K3 surfaces. Joint work with Jesse Pajwani.
