Published in 2019 at "European Biophysics Journal"

DOI: 10.1007/s00249-019-01368-1

Abstract: Ion channel data recorded using the patch clamp technique are low-pass filtered to remove high-frequency noise. Almanjahie et al. (Eur Biophys J 44:545–556, 2015) based statistical analysis of such data on a hidden Markov model… read more here.

Published in 2023 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stad1406

Abstract: The detailed modelling of stellar oscillations is a powerful approach to characterising stars. However, poor treatment of systematics in theoretical models leads to misinterpretations of stars. Here we propose a more principled statistical treatment for… read more here.

Published in 2021 at "Physical review. E"

DOI: 10.1103/physreve.103.012121

Abstract: Surface growth processes can be significantly affected by long-range temporal correlations. In this work, we perform extensive numerical simulations of a (1+1)- and (2+1)-dimensional ballistic deposition (BD) model driven by temporally correlated noise, which is… read more here.

Published in 2022 at "Physical review. E"

DOI: 10.1103/physreve.106.054412

Abstract: Complex spatial systems can experience critical transitions or tippings on crossing a threshold value in their response to stochastic perturbations. While previous studies have well characterized the impact of white noise on tipping, the effect… read more here.

Published in 2022 at "Journal of Synchrotron Radiation"

DOI: 10.1107/s1600577522002739

Abstract: Streaks and Poissonian noise in tomography data are attenuated using a new two-stage multiscale volumetric filtering framework where the degradations are modeled as correlated noise. The procedure is fully automatic, offers improved feature preservation, and… read more here.

Published in 2017 at "IEEE Transactions on Aerospace and Electronic Systems"

DOI: 10.1109/taes.2017.2697598

Abstract: In this paper, the problem of optimal state estimation is studied for fusion of asynchronous multirate multiscale sensors with unreliable measurements and correlated noise. The noise of different sensors is cross-correlated and coupled with the… read more here.

Published in 2022 at "IEEE Transactions on Computational Imaging"

DOI: 10.1109/tci.2022.3214757

Abstract: Sparse signal recovery consists of employing a sparsity promoting regularizer to estimate the underlying signal from an incomplete set of measurements. Typical recovery approaches involve an alternating procedure where the estimate of the signal is… read more here.

Published in 2017 at "Geophysical Prospecting"

DOI: 10.1111/1365-2478.12485

Abstract: We examine the problem of localization of a single microseismic event and determination of its seismic moment tensor in the presence of strongly correlated noise. This is a typical problem occurring in monitoring of microseismic… read more here.
