Time-resolved force distribution analysis [PDF]
BMC Biophysics, 2013 Biomolecules or other complex macromolecules undergo conformational transitions upon exposure to an external perturbation such as ligand binding or mechanical force. To follow fluctuations in pairwise forces between atoms or residues during such conformational changes as observed in Molecular Dynamics (MD) simulations, we developed Time-Resolved Force ...

Lift-up, Kelvin-Helmholtz and Orr mechanisms in turbulent jets [PDF]
, 2020 Three amplification mechanisms present in turbulent jets, namely lift-up, Kelvin–Helmholtz and Orr, are characterized via global resolvent analysis and spectral proper orthogonal decomposition (SPOD) over a range of Mach numbers.

The effect of flight on a turbulent jet: coherent structure eduction and resolvent analysis [PDF]
Journal of Fluid Mechanics, 2023 We study coherent structures in subsonic turbulent jets subject to a flight stream. A thorough characterisation of the effects of a flight stream on the turbulent field was recently performed by Maia et al. (Phys. Rev. Fluids, vol.

Low-frequency resolvent analysis of the laminar oblique shock wave/boundary layer interaction [PDF]
Journal of Fluid Mechanics, 2022 Resolvent analysis is used to study the low-frequency behaviour of the laminar oblique shock wave/boundary layer interaction (SWBLI). It is shown that the computed optimal gain, which can be seen as a transfer function of the system, follows a first ...

A tale of two airfoils: resolvent-based modelling of an oscillator vs. an amplifier from an experimental mean [PDF]
, 2019 The flows around a NACA 0018 airfoil at a Reynolds number of 10250 and angles of attack of alpha = 0 (A0) and alpha = 10 (A10) are modelled using resolvent analysis and limited experimental measurements obtained from particle image velocimetry.

Spatiotemporally resolved multivariate pattern analysis for M/
Human Brain Mapping, 2021 Abstract An emerging goal in neuroscience is tracking what information is represented in brain activity over time as a participant completes some task. While electroencephalography (EEG) and magnetoencephalography (MEG) offer millisecond temporal resolution of how activity patterns emerge and evolve, standard decoding methods present ...

Nonlinear ordered variational inclusion problem involving XOR operation with fuzzy mappings
Journal of Inequalities and Applications, 2020 In the setting of real ordered positive Hilbert spaces, a nonlinear fuzzy ordered variational inclusion problem with its corresponding nonlinear fuzzy ordered resolvent equation problem involving XOR operation has been recommended and solved by employing

A sparsity-promoting resolvent analysis for the identification of spatiotemporally-localized amplification mechanisms [PDF]
AIAA SCITECH 2023 Forum, 2022 This work introduces a variant of resolvent analysis that identifies forcing and response modes that are sparse in both space and time. This is achieved through the use of a sparse principal component analysis (PCA) algorithm, which formulates the ...
