Using publicly accessible data from the EU's Copernicus satellite project I did some (very) simple analysis on vineyard health over the course of a few years and showed how one might use it to measure recovery after a plot is razed due to illness or other planned or unplanned damage to the plants 🌱

It also let's us create some new nerdy plots like a GitHub tile plot, but for runs across the year:

This let's you (re)create some analysis that is only available for subscription users and create plots that aren't available in Strava at all

The slide decks were optimised for the screen in the auditorium (which was 1920x1200) so the slides are best viewed on a screen of that size, or perhaps on another 16x10 screen.

Slides for the trial lecture and disputation are available here: slides.danielroelfs.app/2024-11-19-p... Perhaps some of my illustrations in either slide deck are useful for others in the imaging-genetics or psychiatric genetics field! 😊

Elsevier's parent company RELX has spent about as much money lobbying US politicians in 2023 as large financial companies like JPMorgan Chase and massive car companies like Ford www.opensecrets.org/federal-lobb...

Scientific publishing (Elsevier and Springer-Nature specifically) has higher profit margins than some of the biggest tech companies such as Apple and Google (up to 38% 🤯) . These margins have been stable for years

Open access fees for some of the biggest journals have exceeded $11.000 (120.000 NOK) PER ARTICLE.

The findings in this paper provide some additional genetic support for the dysconnectivity hypothesis in a number of psychiatric disorders as well as identifying potential targets for future etiological studies

This allowed us to find biologically relevant loci (involved in synaptic development and functioning) and discover shared genetic architecture with a number of psychiatric disorders. These overlapping loci are in turn also associated with a number of biologically relevant biological processes

fMRI has quite a lot of noise to say it kindly, so deploying a multivariate approach to look at global resting state functioning instead of individual networks really helped to capture relevant genetic variance.
