Continuous and discrete Bessel wavelet transforms
Journal of Computational and Applied Mathematics, 2003 The authors speak about the continuous and discrete wavelet transforms associated with the Bessel operator, which are defined and studied in the book of \textit{K. Trimèche} [``Generalized harmonic analysis and wavelet packets'' (2001; Zbl 0976.44009)]. The results presented in this paper are given in this book.

Wavelet Estimation of Time Series Regression with Long Memory Processes [PDF]
This paper studies the estimation of time series regression when both regressors and disturbances have long memory. In contrast with the frequency domain estimation as in Robinson and Hidalgo (1997), we propose to estimate the same regression model with ...

Advanced Materials, EarlyView.Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Advanced Materials, EarlyView.Triply‐twinned architected lattices transform deformation from bending to stretching of struts, delivering up to threefold increases in stiffness and strength across polymeric and metallic systems. High‐resolution synchrotron XCT and image‐based simulations reveal how meta‐grain architecture, defects, and AM build orientation govern failure pathways ...
