The asymptotics of stochastically perturbed reaction-diffusion equations and front propagation

open access: yesComptes Rendus. Mathématique, 2020
We study the asymptotics of Allen–Cahn-type bistable reaction-diffusion equations which are additively perturbed by a stochastic forcing (time white noise).

Resonance fluorescence of noisy systems

open access: yesNew Journal of Physics, 2023
Light scattering from resonantly or nearly resonantly excited systems, known as resonance fluorescence (RF), has been gaining importance as a versatile tool for investigating quantum states of matter and readout of quantum information, recently including

Random Weighting-Based Nonlinear Gaussian Filtering

open access: yesIEEE Access, 2020
The Gaussian filtering is a commonly used method for nonlinear system state estimation. However, this method requires both system process noise and measurement noise to be white noise sequences with known statistical characteristics.

Random Matrix Theory Predictions of Dominant Mode Rejection Beamformer Performance

open access: yesIEEE Open Journal of Signal Processing, 2022
Adaptive beamformers use a sensor covariance matrix estimated from data snapshots to mitigate directional interference and attenuate uncorrelated noise.

RENORMALIZED HIGHER POWERS OF WHITE NOISE (RHPWN) AND CONFORMAL FIELD THEORY [PDF]

open access: yesInfinite Dimensional Analysis, Quantum Probability and Related Topics, 2006
The Virasoro–Zamolodchikov *-Lie algebra w∞ has been widely studied in string theory and in conformal field theory, motivated by the attempts of developing a satisfactory theory of quantization of gravity. The renormalized higher powers of quantum white noise (RHPWN) *-Lie algebra has been recently investigated in quantum probability, motivated by the

Some recent results in finitely additive white noise theory [PDF]

open access: yesActa Applicandae Mathematicae, 1994
This is mostly a review paper in which the authors describe results which they have obtained on the subject of finitely additive white noise theory, extending work of \textit{A. V. Balakrishnan} [see, for instance, ``Applied functional analysis'' (1976; Zbl 0333.93051)], and \textit{G. Kallianpur} and \textit{R. L.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Network Localization of Fatigue in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Fatigue is among the most common symptoms and one of the main factors determining the quality of life in multiple sclerosis (MS). However, the neurobiological mechanisms underlying fatigue are not fully understood. Here we studied lesion locations and their connections in individuals with MS, aiming to identify brain networks ...

Association of Corticospinal Tract Asymmetry With Ambulatory Ability After Intracerebral Hemorrhage

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Ambulatory ability after intracerebral hemorrhage (ICH) is important to patients. We tested whether asymmetry between ipsi‐ and contra‐lesional corticospinal tracts (CSTs) assessed by diffusion tensor imaging (DTI) is associated with post‐ICH ambulation.
