Recovery of High-Dimensional Sparse Signals via -Minimization
Journal of Applied Mathematics, 2013 We consider the recovery of high-dimensional sparse signals via -minimization under mutual incoherence condition, which is shown to be sufficient for sparse signals recovery in the noiseless and noise cases.

Respiratory Organ‐on‐a‐Chip for Disease Modeling: From Architecture to Functional Integration
Advanced Healthcare Materials, EarlyView.Respiratory organ‐on‐a‐chip (ROC) models capture key mechanical and cellular cues of the human respiratory system, enabling quantitative dissection of disease mechanisms. This review links ROC architectures to disease modeling, functional integration, and commercialization, and proposes a decision framework that aligns model complexity with mechanistic

An Accelerated MMP With a Pruning Tree Strategy
IEEE Access, 2019 Multipath matching pursuit (MMP) has been developed to solve the sparse signal recovery problems in compressed sensing, which can generate recovery error less than the traditional orthogonal matching pursuit type algorithms in terms of mean square error.

A fast algorithm for sparse signal recovery via fraction function
Electronics LettersIn this article, a fast algorithm is studied to recover the sparse signals. It can be regarded as an extension of the parameterized fast iterative shrinkage‐thresholding algorithm from convex optimization to nonconvex optimization. Numerical results show

A Note on Block-Sparse Signal Recovery with Coherent Tight Frames
Discrete Dynamics in Nature and Society, 2013 This note discusses the recovery of signals from undersampled data in the situation that such signals are nearly block sparse in terms of an overcomplete and coherent tight frame D. By introducing the notion of block D-restricted isometry property (D-RIP)

Advanced Materials, EarlyView.An ion‐mediated structural engineering strategy enables versatile modulation of PVA–Alginate hydrogel microstructure. We systematically examine how different ion combinations affect hydrogel mechanical properties and analyte diffusivity. Applying this novel strategy to hydrogel as the outer membrane in an electrochemical glucose biosensor allows ...
