recommendations! 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.

DOI: 10.1080/00949655.2024.2329976

Abstract: It is now common to have a modest to large number of features on individuals with complex diseases. Unsupervised analyses, such as clustering with and without preprocessing by Principle Component Analysis (PCA), is widely used… read more here.

DOI: 10.1088/1361-6382/ade51a

Abstract: Accurately estimating the statistical properties of noise is important in data analysis for space-based gravitational wave (GW) detectors. Noise in different time-delay interferometry channels correlates with each other. Many studies often assume uncorrelated noise and… read more here.

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.

DOI: 10.1103/kr2l-c97c

Abstract: Correlated noise across multi-qubit architectures is known to be highly detrimental to the operation of error correcting codes and the long-term feasibility of quantum processors. The recent discovery of spatially dependent correlated noise in multi-qubit… read more here.

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.

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.

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.

DOI: 10.1109/lcomm.2024.3362509

Abstract: In this letter, we introduce a Unet-based neural network denoiser-belief propagation (UnetNND-BP) architecture with two training modes to improve the decoding performance of low-density parity-check (LDPC) codes. In the supervised learning mode, UnetNND-BP achieves better… read more here.
