Chondroitin polymerizing factor (ChPF) and proteoglycan synthesis in epithelial cells

Speakers: Stefan Bengtson, Terrence W. Deacon, William F. Martin, Adam Rutherford, Nathan Sanders and Eörs Szathmáry

Antoine Julien (NTNU) will give a talk with title: Tiling spaces, groupoids and K-theory

Abstract:

 In this talk, I will describe how spaces, groupoids and C*-algebras can be associated with aperiodic tilings. In some cases, it is possible to describe the structure of the groupoid combinatorially in terms of augmented Bratteli diagrams. (joint work with Jean Savinien) Time permitting, I will expose a strategy for computing the K-theory of the tiling algebra in terms of the K-theory of AF-algebras (work in progress).

Friday seminar by Jakob Hemmer Hansen

Welcome to the GeoHyd Lunch Seminar Friday 7 February. Meet up in Aud I in the Geology building.

Shahin Jafarzadeh, Post-Doctoral Researcher, ITA

This Friday, 7th of February, in the MaEcovo journal club we will be discussing a paper by Takahashi et al. from 2013:  "Abrupt community transitions and cyclic evolutionary dynamics in complex food webs".

This Thursday we will discuss this interesting recent paper on the likelihood of non-allopatric speciation from the journal Evolution: THE RATE TEST OF SPECIATION: ESTIMATING THE LIKELIHOOD OF NON-ALLOPATRIC SPECIATION FROM REPRODUCTIVE ISOLATION RATES IN DROSOPHILA by Roman Yukilevich. It is not published in an issue yet, but you can download the paper from the link above.

The role of perineuronal nets for spatial representations of the hippocampus

David Ruiz Baños (University of Oslo) holder et seminar med tittelen: On the regularity of densities of SDE's. A classical solution to the stochastic transport equation

Joakim Bergli, UiO

Maxwell's demon was invented almost 150 years ago to illustrate the statistical nature of thermodynamics. Since then, it has stimulated new ideas about the interplay of entropy and information, with new elements entering the discussion even up to the present. I will summarize key ideas which are relevant and then discuss recent work on the possibility of creating a Maxwell demon in nanoelectronic devices.

Jeonghun J. Lee (Aalto University, Helsinki) will give a talk about

On unified analysis of mixed methods for elasticity with weakly symmetric stress.

Abstract: We introduce a framework to construct and analyze mixed finite elements for elasticity with weakly symmetric stress. The framework is based on a connection between mixed methods for elasticity and mixed methods for Stokes equations. We show that some new finite elements can be obtained from it with optimal error bounds.

Friday seminar by Wolfram M. Kürschner

Rajib Dutta (University of Oslo) will give a seminar talk on

Operator splitting methods for Benjamin-Ono (BO) equation

Abstract: We consider the BO equation which describes one-dimensional internal waves in deep water. In this talk, we show that both Godunov and Strang splitting methods converge with the expected rates if the initial data are sufficiently smooth. We also present a proof of convergence of a fully discrete finite difference scheme for this equation.  

Welcome to the GeoHyd Lunch Seminar Friday 31 January. Meet up in Aud I in the Geology building.

On Friday 31st in the MaEcovo jornal club we will be discussing an Ecology Letters paper byMCoy & Pfister, 2014 :  "Historical comparisons reveal altered competitive interactions in a guild of crustose coralline algae".

Variation in armour of three-spine stickleback

This week we will discuss two papers on the proportion of the genome that is encoding, "An integrated encyclopedia of DNA elements in the human genome" authored by The Encode Project Consortium published in Nature 2012, and a critique entitled "On the Immortality of Television Sets: “Function” in the Human Genome According to the Evolution-Free Gospel of ENCODE" by Graur and colleagues published in GBE 2013.

Exosome release. Role of PIKfyve and ERM proteins.

Takuya Takeishi, University of Tokyo, will give a talk with title: Bost-Connes system for local fields of characteristic zero

Abstract: The Bost-Connes system, which describes the relation between quantum statistical mechanics and class field theory, was first constructed by Bost and Connes for the rational field, and generalized for arbitrary number fields by the contribution of many researchers. In this talk, we will introduce a generalization of the Bost-Connes sysmtem for local fields of characteristic zero, and introduce some properties.
