Numerical Computation of the Rosenblatt Distribution and Applications

open access: yesStat, Volume 14, Issue 4, December 2025.
ABSTRACT The Rosenblatt distribution plays a key role in the limit theorems for non‐linear functionals of stationary Gaussian processes with long‐range dependence. We derive new expressions for the characteristic function of the Rosenblatt distribution.

Water Molecular Dynamics During Dough Heating by Fast Field Cycling Nuclear Magnetic Resonance

open access: yesMagnetic Resonance in Chemistry, Volume 63, Issue 11, Page 954-963, November 2025.
Real time FFC measurements confirms the competition of water between gluten and starch granule, gluten hindering the starch water uptake and limits starch swelling in dough. ABSTRACT Measurements of the water 1H nuclear magnetic resonance (NMR) relaxation rate R1 in hydrated starch (SW), gluten (GW) and dough (DW) were performed at different ...

Resting-State Functional MRI Analyses for Brain Activity Characterization: A Narrative Review of Features and Methods. [PDF]

open access: yesEur J Neurosci
Functional connectivity is a popular resting‐state functional MRI analysis. Nevertheless, there are alternative approaches that can be used to characterize the BOLD signal differently, which allow for indirect characterization of brain activity, focusing on regional connectivity, intensity, and complexity.

Fast MR signal simulations of microvascular and diffusion contributions using histogram‐based approximation and recurrent neural networks

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 5, Page 2234-2248, November 2025.
Abstract Purpose Accurate MR signal simulation, including microvascular structures and water diffusion, is crucial for MRI techniques like fMRI BOLD modeling and MR vascular Fingerprinting (MRF), which use susceptibility effects on MR signals for tissue characterization.

QRS Detection in Noisy Electrocardiogram Based on Multi‐Parameter Constrained Stochastic Resonance

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, Volume 20, Issue 11, Page 1745-1756, November 2025.
One major challenge of QRS wave detection is the deleterious impact of inevitable noise in electrocardiogram (ECG) signals, which can deteriorate the detection performance of algorithms. Previous research has shown a nonlinear monostable potential‐based algorithm for enhancing the QRS complex in a noisy environment. Its main mechanism is the stochastic
