Transport of very short lived halogenated substances from the tropical East Pacific to the stratosphere and the influence of El Niño 2015/16

I will report on work in progress on calculations of the motivic homotopy groups of MGL (the algebraic cobordism spectrum) over number fields. It is known that pi_{2n,n}(MGL) is the Lazard ring, and pi_{-n,-n}(MGL) is Milnor K-theory of the base field. We will calculate all of pi_{*,*}(MGL) with the slice spectral sequence (motivic Atiyah-Hirzebruch spectral sequence) over a number field. I will give a brief review of the the tools and sketch the main parts of the calculation: The input from motivic cohomology, the use of C_2-equivariant Betti realization and comparison with Hill-Hopkins-Ravenel to determine the differentials, and settle most of the hidden extensions. 

Irene Brox Nilsen at the Department of Geosciences will be defending her dissertation: Detecting and attributing recent warming in Europe

In the past years there has been several publications on the association between acetaminophen during pregnancy and offspring ADHD symptoms. The aim of the webinar will be to present the recent study, discuss what it adds, and discuss what kind of future studies are needed.

”The Effects of Insularity on Beak Morphology in a Hybrid and a Non-Hybrid Species”

Molecular simulations of the reversible mechanical unfolding of molecular assemblies

I will discuss the results of force probe molecular dynamics simulations of  the mechanical unfolding of model systems showing reversible refolding. The discussion will focus on a question discussed vigorously rescently,  the dependence of the results on the compliance of the pulling device.  It is shown that for the system considered a simple harmonic approximation can be used to extend the standard model used for the interpretation of kinetic parameters obtained. The new model  allows to extract additional information about the stiffness of the free energy landscape of the unfolding transition.

Master of Science Jonas Gliß at Department of Physics will be defending the thesis 

"Passive UV remote sensing of volcanic sulphur and halogen emissions"

for the degree of PhD

Welcome to our GEOHYD Lunch Seminar Friday 10th November @ 12:15 in Aud 1, The Geology building. The seminar is given by PhD student Chloé Scholzen.

Vasco Henriques, Postdoc, ITA

This Friday, November 10th, we're discussing a paper by Benson et al. (2017): "Cope's rule and the adaptive landscape of dinosaur body size evolution".

Hope to see you there!

Doctoral candidate Master in Physics Jonas Gliß at Department of Physics will give a trial lecture on the given topic:

"Effects from ash and aerosols in volcanic plumes on SO2 emission measurements, in specific using UV-cameras".

I Science of Fiction er det denne gangen duket for David Cronenbergs The Fly, en film om hvor galt det kan gå. Science gone mad!

Welcome! Open for all. Main lecture: Marcia McNutt, geophysicist and president of the US Academy of Sciences, on: "Reconciling Energy Resource Extraction with Ecosystem Health – Lessons from Deepwater Horizon". (The Fridtjof Nansen Lectures on Ocean Life are part of the UiO Day of the Arctic).

Come and meet some of our both interested and interesting lecturers and connected researchers, all of whom offer master’s theses from the research they are doing.

Identifying protein interaction partners for DEXI, encoded by the multiple sclerosis associated dexamethasone-induced gene, DEXI

I will discuss the algebra structure of the E_2-term of the mod 2 Adams spectral sequence for tmf, given by the cohomology Ext_{A(2)}(F_2, F_2) of A(2).  We (Bruner & Rognes) use Groebner bases to verify the presentation given by Iwai and Shimada, with 13 generators and 54 relations. Thereafter I will discuss the relationship between differentials and Steenrod operations in the Adams spectral sequence for E_\infty ring spectra.  

Thomas Konstandin, DESY

I will give an overview over the potential impact of (recent and future) observations of gravitational waves on cosmology and particle physics. This ranges from the measurement of the equation of state of QCD and the Hubble expansion parameter to (black hole) dark matter and inflation. I will dwell a little bit more on the connection to cosmological phase transitions that are mostly interesting to future space-based gravitational wave observatories.

(The slides will be available here)

Late Lunch Talk by Tore Slagsvold, CEES, University of Oslo

Molecular characterization of T-cell activation Rho-GTPase activating protein

Pawel Kasprzak (Warzaw) will give a talk with title " Quantum actions on discrete quantum spaces"

Abstract:

To any action of a compact quantum group on a von Neumann algebra which is a direct sum of factors we associate an equivalence relation corresponding to the partition of a space into orbits of the action. We show that in case all factors are finite-dimensional (i.e. when the action is on a discrete quantum space) the relation has finite orbits.  We then apply this

i) to generalize the classical theory of Clifford, concerning the restrictions of representations to normal subgroups, to the framework of quantum subgroups of discrete quantum groups, itself extending the context of closed normal quantum subgroups of compact quantum groups; ii) to the context of idempotent states showing that the  algebra of invariant elements is finite dimensional if and only if the corresponding state is normal. Joint work with K. De Commer, A. Skalski and P. Sołtan.

Kirsten Bomblies from The John Innes Centre, Norwich, UK, will give the talk "The evolution of meiosis in diploid and tetraploid Arabidopsis arenosa"
