Site-Specific Effects of Online rTMS during a Working Memory Task in Healthy Older Adults

open access: yesBrain Sciences, 2020
The process of manipulating information within working memory is central to many cognitive functions, but also declines rapidly in old age. Improving this process could markedly enhance the health-span in older adults.

Modelling Electricity Forward Markets by Ambit Fields [PDF]

open access: yesSSRN Electronic Journal, 2011
This paper proposes a new modelling framework for electricity forward markets based on so‐ called ambit fields. The new model can capture many of the stylised facts observed in energy markets and is highly analytically tractable. We give a detailed account on the probabilistic properties of the new type of model, and we discuss martingale conditions ...

3D marine controlled-source electromagnetic modeling using an edge-based finite element method with a block Krylov iterative solver

open access: yesOpen Geosciences, 2022
An edge-based finite element method for the numerical modeling of electromagnetic fields in complex media is presented. We used the analytical solution on an electric field in a homogeneous half space to develop a source correct factor to reduce the ...
