”Genetic structure of diploid (2n = 12,14) Scurvygrasses (Cochlearia) with emphasis on Icelandic populations”

Shinji Mukohyama, Yukawa Institute for Theoretical Physics, Kyoto University

Last week we read a paper that used Principal Component analysis, so this week we will discuss why this type of analysis can mislead inferences. Friday, 25th : "Comparative Analysis of Principal Components Can be Misleading" Uyeda et al. 2015.

Antoine Julien, NTNU, will give a talk with title: Links between cut-and-project tilings and Diophantine approximation

Abstract: Cut-and-project tilings are obtained by cutting a slice of a higher dimensional lattice and projecting it on a lower dimensional space. The result is a point set which is regular enough (since it originates from a lattice), but is not periodic, provided the direction of the slice is irrational in a suitable sense. In one dimension, typical examples of this construction are Sturmian subshifts. It is known that some of their dynamical properties depend on the arithmetic properties of a certain parameter. In this talk, I will recall some known results by Hedlund and Morse on Sturmian subshifts. Then, I will describe how, even in higher dimensions, the repetition properties of some cut-and-project sets can be linked to problems of simultaneous Diophantine approximation. This is joint work with A. Haynes, H. Koivusalo and J. Walton.

Title: Comparing the Norkyst 800 model to in situ measurements in the outer Oslofjord

Supervisor: Joe LaCasce

This week we will discuss a study on An early modern human from Romania with a recent Neanderthal ancestor which was recently published in Nature. In the study Fu and colleagues report findings of 6-9% neanderthal DNA in a modern human.

Expression dynamics of long non-coding RNAs in the sponge Sycon ciliatum

Kåre Olaussen, NTNU Trondheim

After 100 years people are still trying to modify (or mutilate) the Einstein General Theory of Relativity. I will first give a general overview of various possibilities, as I learned at a workshop this summer.

Next I will discuss in more detail the possibility of a non-minimal coupling of Einstein gravity to scalar fields, and some modest computations I have done with a master student on that model (in the Robertson-Walker geometry).

The presentation will mainly be aimed at an audience with limited experience with general relativity.

(Slides will be available after the talk).

Audun Mathias Øygard (Master student, Dept. of Mathematics, UiO) will give a seminar in the lunch area, 8th floor N.H. Abel's House at 14:15 September 15th: Measuring similarity of classified advertisements using images and text, with applications to recommendation and search at finn.no

Master i farmasi Angela Lupattelli ved Farmasøytisk institutt vil forsvare sin avhandling for graden ph.d: Safety aspects and patterns of medication use in pregnancy. With special focus on psychotropic medication and mental health.

Preserving traditions is important, not least barely born traditions, such as the Minglemøte, meant to be at the end of every month containing an ‘r’ (plus perhaps some more). In any case, we’re having another, next Friday Sepember 11 in the lobby. There will be cake and coffee, and there will be (only two this time, to give a chance of having some actual mingling going on) presentations. Notably a summary of the two SFF (Center of Excellence) proposals that the ITA will be sending in this fall: On the “Oslo Cosmology Center" and on  “The Rosseland Centre for Solar Physics” and what they could mean for the institute.

All are invited, we need critical acclaim and perhaps some constructive criticism as well.
