The frictional behavior of surfaces is a problem of great scientific and practical significance. Recent progress in molecular scale modeling allows us to determine the coefficient of friction for nanoscale surfaces from first principles using molecular dynamics modeling. However, inverse design, that is, designing surfaces with specific frictional propeties is still a complex and largely unsolved challenge in part due to the enormous space of possible surface configurations. Here, we demonstrate how we can use physical forward modeling to find the frictional properties of a set of surfaces that can serve as a training set to design machine learning models. In this talk, we demonstrate both discriminative and generative models for frictional surface design and analyze what physical principles the machine learning models have learned in this process.

his talk discusses a nonparametric inference framework for occupation time curves derived from wearable device data. Such curves provide the total time a subject maintains activity above a given level as a function of that level. Taking advantage of the monotonicity and smoothness properties of these curves, we develop a likelihood ratio approach to construct confidence bands for mean occupation time curves. An extension to fitting concurrent functional regression models is also developed. Application to wearable device data from an ongoing study of an experimental gene therapy for mitochondrial DNA depletion syndrome will be discussed. Based on joint work with Hsin-Wen Chang (Academia Sinica).
Title: Global simulations of the interactions between climate and the economy
Speaker: Trude Storelvmo, UiO
Welcome to our dScience lunch seminar in the Science Library, with Trude Storelvmo from the Department of Geosciences.
Angiosperm species display a huge variation in the form of their inflorescences, flowers and fruits. This diversity has evolved through modifications in the gene regulatory networks (GRNs), which underlie the development of these structures. To understand how gene evolution brings about the divergence of traits, we focus on the MADS-domain transcription factors, which play important roles in the GRNs that regulate flowering and fruit development. We study how gene regulatory networks can change between species, investigating both the specificity of protein-protein and of DNA-protein interactions, as well as divergence in expression profiles. The main topic of our studies is the MADS-domain transcription factor FRUITFULL (FUL), which has a conserved function in the regulation of flowering time, fruit development and woodiness throughout the angiosperms.

We are thrilled to announce an upcoming event featuring the acclaimed novel "Dancing Amid Fire, Rising Above Ruins" by Essmat Sophie. This event promises to be an engaging and thought-provoking discussion on the themes of identity, intersectional oppression, exile, politics, history, and the marginalized Kurdish community in Iran.

During this cold winter in Oslo, we certainly all have experienced the unsteady nature of friction and the sudden loss of stress bearing capacity that initiates catastrophic sliding. A similar kind of frictional rupture arises at the onset of a wide variety of natural disasters that includes earthquakes, landslides, as well as snow avalanches. In this talk, I will focus on the incipient stage of these catastrophic events that is characterized by the local nucleation of failure and its rapid propagation towards intact regions of the material. I will discuss how the analogy to fracture mechanics can be exploited to describe the dynamics of these rupture fronts and develop quantitative models to characterize the onset of failure in geomaterials.
