Probing iron in Earth’s core with molecular-spin dynamics

Svetoslav Nikolov, Kushal Ramakrishna, Andrew Rohskopf, Mani Lokamani, Julien Tranchida, John Carpenter, Attila Cangi, Mitchell A. Wood - PNAS December 12, 2024

Dynamic compression of iron to Earth-core conditions is one of the few ways to gather important elastic and transport properties needed to uncover key mechanisms surrounding the geodynamo effect. Herein, a machine-learned ab initio derived molecular-spin dynamics (MSD) methodology with explicit treatment for longitudinal spin-fluctuations is utilized to probe the dynamic phase-diagram of iron…

A high-order fully Lagrangian particle level-set method for dynamic surfaces

Lennart J Schulze, Sachin KT Veettil, Ivo F Sbalzarini - Journal of Computational Physics, Volume 515, 15 October 2024, 113262

We present a fully Lagrangian particle level-set method based on high-order polynomial regression. This enables meshfree simulations of dynamic surfaces, relaxing the need for particle-mesh interpolation. Instead, we perform level-set redistancing directly on irregularly distributed particles by polynomial regression in a Newton-Lagrange basis on a set of unisolvent nodes…

Quantum delocalization, structural order, and density response of the strongly coupled electron liquid

Tobias Dornheim, Panagiotis Tolias, Jan Vorberger, Zhandos A. Moldabekov - EPL, 147 (2024) 36001

We investigate the impact of electronic correlations and quantum delocalization onto the static structure factor and static density response function of the strongly coupled electron liquid. In contrast to a classical system, the density response of the electron liquid vanishes on small length scales due to quantum delocalization effects, which we rigorously quantify in terms of imaginary-time correlation functions and dynamic Matsubara response functions…

Spatial computational modelling illuminates the role of the tumour microenvironment for treating glioblastoma with immunotherapies

Blanche Mongeon, Julien Hébert-Doutreloux, Anudeep Surendran, Elham Karimi,Benoit Fiset,Daniela F. Quail, Logan A. Walsh, Adrianne L. Jenner, Morgan Craig - npj Systems Biology and Applications volume 10, Article number: 91 (2024)

Glioblastoma is the most common and deadliest brain tumour in adults, with a median survival of 15 months under the current standard of care. Immunotherapies like immune checkpoint inhibitors and oncolytic viruses have been extensively studied to improve this endpoint. However, most thus far have failed. To improve the efficacy…
