Wavelet Transform‐Based Atomic Force Microscopy: A Computational Paradigm for Dynamic Nanoscale Imaging and Characterisation

Small Science, Volume 6, Issue 8, August 2026.
Wavelet transform‐based AFM enables real‐time nanoscale imaging by applying wavelet analysis to raw cantilever deflection signals. It reveals non‐linear, transient and multi‐frequency dynamics beyond conventional steady‐state methods. Integrated with adaptive filtering and digital twin modelling, it produces high‐resolution, information‐rich maps of ...

Comparison of wavelet approximation order in different smoothness spaces

International Journal of Mathematics and Mathematical Sciences, 2006
In linear approximation by wavelet, we approximate a given function by a finite term from the wavelet series. The approximation order is improved if the order of smoothness of the given function is improved, discussed by Cohen (2003), DeVore (1998), and ...

Efficient low‐dose CT image enhancement using MobileMamba‐UNet with wavelet‐enhanced long‐range modeling

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Deep learning has become a dominant paradigm for low‐dose computed tomography (LDCT) image reconstruction. Nevertheless, existing approaches still struggle to simultaneously achieve accurate structural detail preservation and computational efficiency, particularly when handling long‐range contextual dependencies. Purpose To design a

Enhancing Volatility Prediction: A Wavelet‐Based Hierarchical Forecast Reconciliation Approach

Journal of Forecasting, Volume 45, Issue 4, Page 1652-1664, July 2026.
ABSTRACT Forecasting realized volatility (RV) has been widely studied, with numerous techniques developed to enhance predictive accuracy. Among these techniques, the use of RV decompositions based on intraday asset returns has been applied. However, the use of a frequency‐based decomposition, which provides unique insights into the dynamics of RV ...

Employee Perceptions of Coaching Relationship Quality: A Change‐Over‐Time Study of Job Satisfaction and Turnover Intentions

Asia Pacific Journal of Human Resources, Volume 64, Issue 3, July 2026.
ABSTRACT To remain competitive, organisations increasingly rely on human resources (HR) to operate as a strategic business partner responsible for developing employee capability. Although prior research highlights the centrality of supervisor–employee relationships for effective coaching, little is known about whether employees' perceptions of the ...
