Translation from research to value creation can not be done without understanding immaterial property and how to protect it. How can we ensure that we capture and exploit ideas? How can we develop collaboration between academia and business? We invite researchers and small and medium sized enterprises (SMEs) to an educational day on IPR!

Nature has invented ingenious aerodynamic design solutions, some of which are critical for plants as wind dispersal of seeds and fruits is coupled to their flight performance. This formulates into an optimization problem for plants: large seed wings can lead to increased lift and more efficient dispersion, but are costly for the tree to build and can more easily be trapped in the canopy. Double winged seeds/fruits separate from their tree when a specific level of dessication is reached, and autorotate as they descend to the ground. This leads to the question: how is the wing curvature of seeds/fruits linked to their flight performance? To answer this, we develop a theoretical model that suggests the existence of an optimal wing curvature that yields maximal lift. To further understand the interplay between the flow and the wing geometry, we perform a synthetic seed adaptation by deploying 3D printing of double winged fruits that we use in flight experiments, where we span the phase space of aerial dynamics by changing the of wing curvature and seed/fruit weight. Experiments confirm that there is a sweet-spot in curvature to maximise the flight time consisted with geometrical measurements from a wide range of seeds in Nature. Our results highlights the importance of not curving too much or too little for helicopter fruits to have an optimal flight performance.

This Friday, November 24th, we're discussing a paper by Uyeda et al. (2017): "A General Model for Estimating Macroevolutionary Landscapes".

Hope to see you there!

In my job as research adviser, I receive a lot of questions about rights, possibilities and problems in connection with scientific publishing and open access. Both EU and the Norwegian Research Council have rules about this, and there is also a UiO policy in place that is relevant for all employees. I will give a short presentation to try to clear up what you have to, must, may, could and should related to Open access. In my experience many of you have the same questions about these issues, so I hope you bring your questions with you and we can address them in the seminar.

I will discuss the differential structure in the mod 2 Adams spectral sequence for tmf, leading to its E_\infty-term.  These calculations were known to Hopkins-Mahowald; in their current guise they are part of joint work with Bruner.

The origin and nature of the dark matter in the Universe is one of the most pressing questions in fundamental physics. The combination of particle physics and cosmology has proven to be a successful avenue leading to the well-established theory of big bang nucleosynthesis that explains the primordial abundances of light elements. In the similar manner an extrapolation to even earlier times in the Universe has led to the WIMP (Weakly Interacting Massive Particle) freeze-out paradigm - one of the best motivated explanations of the dark matter relic abundance measured today. However, despite an enormous experimental effort no conclusive hint for WIMPs has been found, putting pressure on the WIMP dark matter explanation. In this talk we examine new avenues beyond the standard WIMP picture. We show that scrutinizing the well-known co-annihilation scenario and dropping the commonly made assumption of chemical equilibrium between co-annihilating partners offers new phenomenological possibilities. By solving the full coupled set of Boltzmann equations we find solutions that accommodate the measured dark matter density while requiring very small couplings that are in accordance with current null-results in WIMP searches.

Magnetically induced current densities of electronic excited states at the MCSCF level

In this talk, I will present recent results about magnetically induced currents for low-lying electronic states at the MCSCF level of theory. Based on the strength of  current-density susceptibility, we will discuss (anti)aromaticity of the electronic states.
