Exploring the Nexus Between Sustainability Index and Central European Stock Markets Competitiveness: Evidence Through Time–Frequency Analysis and SHAP

Journal of Forecasting, Volume 45, Issue 5, Page 2213-2237, August 2026.
ABSTRACT Sustainability has become an important factor shaping financial markets and investor behavior. This paper examines the relationship between sustainability indices and Central European stock markets using a time–frequency approach. Wavelet coherence is employed to capture time‐varying co‐movements between sustainability indices and stock market

Self‐Supervised Deep Learning Framework for Rician Distribution Based Denoising and Modeling of Multi‐b Prostate Diffusion MRI

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 928-942, August 2026.
ABSTRACT Purpose Convolutional neural networks (CNNs) are evaluated for improved and accelerated denoising and Rician bias correction in multi‐b DW images with simultaneous signal modeling. Methods Prostate diffusion images from 46 individuals acquired at 20 linearly distributed b‐values (bmax=2000s/mm2) without averaging were used for self‐supervised ...

Investigating the Sensitivity of the Diffusion MRI Signal to Magnetization Transfer and Permeability via Monte‐Carlo Simulations

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 960-974, August 2026.
ABSTRACT Purpose Magnetization transfer (MT) and water exchange via permeability operate on a similar spatiotemporal scale to water diffusion. In this study, we use a simulation‐based approach to characterize how MT and permeability impact (1) diffusion‐weighted MRI (dMRI) measurements from cylindrical substrates and (2) parameter estimation using a ...

Restriction‐Weighted Q‐Space Trajectory Imaging (ResQ): Toward Mapping Diffusion‐Time Effects With Tensor‐Valued Diffusion Encoding in Human Prostate Cancer Xenografts

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Tensor‐valued diffusion MRI enables microstructure characterization but can be confounded by the presence of restricted diffusion. We introduce ResQ, a framework that incorporates restriction weighting into q‐space trajectory imaging and we evaluate it in a longitudinal study of prostate cancer xenografts treated by external radiotherapy. ResQ revealed

Differentiating between Alzheimer’s disease, amnestic mild cognitive impairment, and normal aging via diffusion kurtosis imaging

Neural Regeneration Research, 2019
Diffusion kurtosis imaging can be used to assess pathophysiological changes in tissue structure and to diagnose central nervous system diseases. However, its sensitivity in assessing hippocampal differences between patients with Alzheimer’s disease and ...

From armed roots to airline routes in South America: A dual imprinting perspective

Strategic Management Journal, Volume 47, Issue 8, Page 2235-2271, August 2026.
Abstract Reserch Summary We propose that founding partner relationships can leave distinct imprints on organizations that differ in durability and in how they respond to subsequent changes involving the founding partner. Examining South American airlines founded between 1919 and 1984, we argue and find that such relationships simultaneously create an ...
