Abstract: Frailty is a multi-system dysregulation leading to a loss of physiological reserve known to predict dementia. However, its link with neurodegenerative alterations of the central nervous system (CNS) is not well understood at present. We investigated the association between the biomechanical response of the CNS and frailty in older adults suspected of normal pressure hydrocephalus (NPH) presenting markers of multiple comorbid neurodegenerative pathologies, including pathologies of Alzheimer’s Disease. The biomechanical response of the CNS was characterized from phase contrast magnetic resonance imaging and intracranial pressure monitoring during a lumbar infusion test. Frailty was assessed with an index of health deficit accumulation. We found a significant association between the CNS biomechanical response and frailty, with an effect size comparable to that between frailty and age, the latter being the strongest known risk factor of frailty. The CNS biomechanical characterization may help to understand how frailty is related to neurodegeneration and detect the shift from normal to pathological brain ageing.

This talk is part of the Mechanics Lunch Seminar series. That means 20min talks plus discussion in an informal setting.

C*-algebra seminar talk by Ulrik Enstad (University of Oslo)

I will present some of my work on the solid-electrolyte interface. There, so-called electric double layers (EDLs) can form that consist of electrons on the solid screened by a diffuse cloud of ions in the adjacent liquid. EDLs are of paramount importance to many processes in physical chemistry, soft matter and biophysics, as well as in EDL capacitors and modern "supercapacitors". My work on EDLs focused on their (out-of-equilibrium) formation through questions like: 'On what timescale does an electrolyte respond to an applied temperature or voltage difference?', 'How does the (local) temperature in an electrolyte react to an applied electric field?', and 'How is the EDL affected by a change in temperature or salt concentration?'. I will show how answers to these questions suggest new methods for harvesting sustainable energy, for instance, from the controlled mixing of seawater and river water.

DuMux  (short for "Dune for Multi- {Phase, Component, Scale, Physics,…} flow and transport in porous media") is  a free and open-source simulator for flow and transport processes in porous media. DuMux is modern C++ code based on the scientific software framework Dune (Distributed and Unified Numerics Environment) and has a focus on modularity and reusability. 

The main features and ideas behind DuMux will be introduced with several examples from recent research projects.

This talk is part of the Mechanics Lunch Seminar series. That means 20min talks plus discussion in an informal setting.

On 7-9 September 2020, the conference on high-dimensional stochastics will take placeas a virtual meeting under the auspices of at the Wolfgang Pauli Institute (WPI) in Vienna, Austria. The conference is an activity within the thematic program "Mathematics for Risk in Finance and Energy" at the WPI. 

We aim to bring together an interdisciplinary group of leading researchers with interest in high dimensional stochastic modeling. Particular emphasis will be given to infinite dimensional Markov processes, SPDEs, population dynamics, high dimensional statistics and connections to financial and energy modeling. We welcome participants from academia and industry to take part in this event.
