Quantum-Mechanical Calculation of Ionization-Potential Lowering in Dense Plasmas

Physical Review X, 2014
The charged environment within a dense plasma leads to the phenomenon of ionization-potential depression (IPD) for ions embedded in the plasma. Accurate predictions of the IPD effect are of crucial importance for modeling atomic processes occurring ...

Protein-ligand binding affinities from large-scale quantum mechanical simulations

, 2012
The accurate prediction of protein-drug binding affinities is a major aim of computational drug optimisation and development. A quantitative measure of binding affinity is provided by the free energy of binding, and such calculations typically require ...

Magnetic refrigeration for nanoelectronics on a cryogen-free platform [PDF]

, 2015
Nanostructured samples serve as a playground of solid state physics due to their vast diversity of applications. In addition to various fabrication recipes and measurement methods, the temperature at which these experiments are performed plays a crucial ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Whistler Chorus Amplification in the Magnetosphere: The Nonlinear Free‐Electron Laser Model and the Ginzburg‐Landau Equation

Geophysical Research Letters
We present a novel nonlinear model for whistler‐mode chorus amplification based on the free‐electron laser (FEL) mechanism. First, we derive the nonlinear collective variable equations for the whistler‐electron interaction.

Diffusion Spectrum Imaging Maps Early Axonal Loss and a Unique Progressive Signal in Neuronal Intranuclear Inclusion Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To delineate specific in vivo white matter pathology in neuronal intranuclear inclusion disease (NIID) using diffusion spectrum imaging (DSI) and define its clinical relevance. Methods DSI was performed on 42 NIID patients and 38 matched controls.

An extended model of the quantum free-electron laser

, 2017
Previous models of the quantum regime of operation of the Free Electron Laser (QFEL) have performed an averaging and the application of periodic boundary conditions to the coupled Maxwell – Schrödinger equations over short, resonant wavelength intervals ...

Equilibrium and dynamics of collisionless current sheets

, 2009
In this thesis examples of translationally invariant one-dimensional (1D) Vlasov-Maxwell (VM) equilibria are investigated. The 1D VM equilibrium equations are equivalent to the motion of a pseudoparticle in a conservative pseudopotential, with the ...

Gamma-ray free-electron lasers: Quantum fluid model

, 2015
A quantum fluid model is used to describe the interaction of a nondegenerate cold relativistic electron beam with an intense optical wiggler taking into account the beam space-charge potential and photon recoil effect.
