Hidden Markov model analysis of subcellular particle trajectories
… traditional approaches that involve fitting a mean square displacement (MSD) curve calculated from the particle trajectories. Our HMM algorithms are shown to be more accurate than existing MSD algorithms for heterogeneous trajectories which switch between multiple phases of motion.

Chaotic behaviour of charged particles in electromagnetic fields
… field lines, using statistical measures like the mean square displacement (MSD) and calculating diffusion coefficients. Lastly, we present the construction of explicit near-symplectic mappings of the symmetric tokamap with Lie-generating functions.

DYNAMICS AND COMPACTION OF CONGESTED AND/OR CONFINED DNA
… both linear and circular DNA is discussed. The mean square displacement (MSD), reorientation correlation, and the radius of gyration of entangled lambda-phage DNA and the MSD of cosmid DNA were obtained with fluorescence microscopy. From an analysis of the end-segment MSD of lambda DNA with …

Phonon dispersion curves and atomic mean square displacement for several fcc and bcc materials
The atomic mean square displacement (MSD) and the phonon dispersion curves (PDC's) of a number of face-centred cubic (fcc) and body-centred cubic (bcc) materials have been calclllated from the quasiharmonic (QH) theory, the lowest order (A2 ) perturbation theory (PT) and a recently proposed Green's …

Dynamics Of Biopolymers On Nanomaterials Studied By Quasielastic Neutron Scattering And Mdsimulations
… Neutron Scattering (QENS). We investigated the mean square displacement (MSD) of hydrated and dry β-Casein as a function of temperature, to study the effect of hydration on their flexibility. The Elastic Incoherent Structure Factor (EISF) in the energy domain reveals the fraction of hydrogen …

Probing water properties and cationic exchange in calcium-silicate-hydrate : an atomistic modeling study
… in the nuclear fuel cycle are investigated by means of atomistic simulations. The first is the structural and dynamic nature of water confined in the nano-pores of the highly disordered calcium-silicate-hydrate (C-S-H) which is the major binding phase of cement. The microscopic structure and …

Separation and Properties of La₂O₃ in Molten LiF-NaF-KF Salt
… was calculated according to the function of mean square displacement (MSD) of time generated by the Einstein-Smoluchowshi equation. The viscosity and ionic conductivity were obtained by combining the self-distribution coefficient with the Einstein-Stokes formula and Nernst-Einstein equation.

Atomic Modelling of Disorder in Metal Nanocrystals
The atomic mean square displacement (MSD,  ̄(σ_i^2 ) ) is often used in computational materials science studies to calculate measurable properties from the atomic trajectories of simulations; for example, the diffusion coefficient, which according to Einstein relations (Einstein 1905) on the …

Molecular Dynamics study of defect evolution mechanisms in material of interests for quantum technologies [Studio di Dinamica Molecolare dei meccanismi di evoluzione dei difetti nei materiali di interesse per le tecnologie quantistiche]
… il metodo dello spostamento quadratico medio (MSD) e un metodo di conteggio della frequenza basato sul centro di massa (COM). Analisi di Voronoi e di rottura sono state applicate per tracciare i salti atomici. Mentre il metodo MSD fornisce una stima semplice della diffusività, manca di …
