International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.ABSTRACT This paper proposes a novel adaptive topology optimization framework that integrates the Virtual Element Method (VEM) with the Material‐Field Series Expansion (MFSE). Within the VEM‐MFSE framework, we propose a material gradient‐driven adaptive strategy, in which elements are refined in regions with higher material density gradients as the ...

Design method of nonsubsampled graph filter banks
Dianzi Jishu Yingyong, 2019 In order to overcome the problem that it is difficult to accurately define the downsampling operation for a generalized graph signal in graph filter banks, this paper focuses on the design algorithm of nonsubsampled graph filter banks.

Orthogonal Wavelets via Filter Banks: Theory and Applications [PDF]
, 2000 Wavelets are used in many applications, including image processing, signal analysis and seismology. The critical problem is the representation of a signal using a small number of computable functions, such that it is represented in a concise and ...

Energy Science &Engineering, Volume 14, Issue 1, Page 583-610, January 2026.Decentralized energy systems are gaining momentum, and microgrids have become a vital component of the modern power landscape. Yet, maintaining power quality within these systems presents ongoing challenges due to the presence of nonlinear loads, variable renewable energy sources, and frequent switching operations.

Human Brain Mapping, Volume 47, Issue 1, January 2026.This cross‐validation study assessed the comparability of high‐field (HF; 3T) and ultra‐low‐field (ULF; 64mT) volumes in infants for brain regions associated with antenatal maternal anemia. Key findings demonstrated strong agreement between HF and ULF volume estimates for the caudate nucleus, putamen, and corpus callosum in infants between 3 and 18 ...

A Novel Multiband Spectrum Sensing Method Based on Wavelets and the Higuchi Fractal Dimension
Sensors, 2019 In this work, two novel methodologies for the multiband spectrum sensing in cognitive radios are implemented. Methods are based on the continuous wavelet transform (CWT) and the multiresolution analysis (MRA) to detect the edges of available holes in the

Protein Science, Volume 35, Issue 1, January 2026.Abstract Intrinsically disordered proteins (IDPs) lack stable tertiary structure and instead exist as dynamic ensembles of conformations, playing essential roles in cellular regulation, signaling, and disease. As structural ensembles of IDPs become increasingly available through databases such as the Protein Ensemble Database (PED) and various ...

Multi-Scale Pixel-Based Image Fusion Using Multivariate Empirical Mode Decomposition
Sensors, 2015 A novel scheme to perform the fusion of multiple images using the multivariate empirical mode decomposition (MEMD) algorithm is proposed. Standard multi-scale fusion techniques make a priori assumptions regarding input data, whereas standard univariate ...
