Late Lunch Talk by Cecilia Helmerson, CEES

By Fabienne Krauer from Institute of Social and Preventive Medicine (ISPM), University of Bern, Switzerland

Felix Kahlhoefer, DESY (Hamburg)

I will discuss the motivation, the advantages and the problems of using simplified models as a tool to interpret LHC searches for dark matter. I will present a few examples for how this approach can be used to understand the complementarity of different dark matter search strategies. Finally, I will focus on various consistency conditions that should be imposed even on the most simplified models. These conditions can imply the presence of additional new particles and interactions that may change the phenomenology of the model in important ways.

(The slides are now available)

Timo Koski (Dept. of Mathematics, Royal Institute of Technology, Stockholm) will give a seminar in the lunch area, 8th floor Niels Henrik Abels hus at 14:15.

Welcome to the GeoHyd Lunch Seminar on Monday April 25th @ 12:15 in Aud. 2.

Jack Carlyle, Postdoc , ITA

This Friday the 22nd of April we will discuss a paper by Kaji et al. (2016): "Functional transformation series and the evolutionary origin of novel forms: evidence from a remarkable termite defensive organ".

Hope to see you there!

Population models such as IPM's allow the inclusion of continuous traits for demographic analysis, and therefore the tracking of phenotypic change over time. Especially in the case of rapid phenotypic change, it was therefore only a matter of time until methods were developed to identify the sources of such change as evolution, plasticity or demography. One such method is the age-structured Price equation, developed by Coulson & Tuljapurkar in the paper we are discussing this session:

"The Dynamics of a Quantitative Trait in an Age-structured Population Living in a Variable Environment" (Coulson & Tuljapurkar 2008)

This thursday, at the Speciation Journal Club, we will discuss a paper entitled 

"Determining epistatic selection in admixed populations" by Schumer and Brandvain 2016 (Molecular Ecology)

Mol. Biol. Evol. 32(10):2547–2558 doi:10.1093/molbev/msv126

A Scandinavian Gathering Around Remarkable Discrete Mathematics

Abstract: The talk will be on positive linear maps of the n x n matrices into itself, a topic which has become quite popular in quantum information theory.  The maps closest to physics are the completely positive ones. I´ll discuss an approximation by a completely positive map to a positive map via the trace , called the “structural physical approximation”, the SPA of the map. Much of the talk will circle around a counter example  to a conjecture on the SPA.

Sofia Tirabassi (UiB), gives the Seminar in Algebra and Algebraic Geometry:

Title: Characterization of product of theta divisors

Abstract: This is a joint work with Z. Jiang and M. Lahoz. We give a new cohomological characterization of product of theta divisors in principally polarized abelian varieties and we completely classify n-varieities with of maximal albanese dimension and with irregularity 2n-1 and euler characteristic 1, extending lower dimensional results of Hacon--Pardini. I will do my best to keep the first hour enjoyable and entertaining also for graduate students with background in algebraic geometry (and related areas).

Late Lunch Talk by José Cerca de Oliveira from the Natural History Museum of Oslo

Anders Holmberg (Statistics Norway, SSB) will give a seminar in the lunch area, 8th floor Niels Henrik Abels hus at 14:15.

With the advent of long read sequencers such as the PacBio RS II, the goal of near-perfect de novo reconstructions of unknown genomes is once again a realistic possibility. We will explain why, and further give a hypothesis as to why assemblers have improved only marginally since the era of the Human Genome Project circa 2000.

By Martijn van de Pol & Callum Lawson

Welcome to the GeoHyd Lunch Seminar on Friday April 15th @ 12:15 in the old Library in the basement of the Geology building.

Karl Ove Moene, Professor - Centre for the Study of Equality, Social Organization, and Performance

This Friday the 15th of April we will discuss a paper by Benson et al. (2016): "Near-Stasis in the Long-Term Diversification of Mesozoic Tetrapods".

Hope to see you there!

”Red deer migration and dietary quality: testing the role of landscape characteristics for the forage maturation hypothesis”

This thursday, at the Speciation Journal Club, we will discuss a paper entitled 

"Excavating Neandertal and Denisovan DNA from the genomes of Melanesian individuals" by Vernot et al. 2016 (Science)

Abstract: In the classification program for C*-algebras some of the usual assumptions put on the algebras are that they are simple or have at most have finitely many ideals. We often also want algebras that have real rank 0. In this talk we will discuss how to classify certain graph algebras with uncountably many ideals and without real rank 0. There will be examples and applications. Joint work with S. Eilers, G. Restorff, and E. Ruiz
