Tissue Engineered Human Elastic Cartilage From Primary Auricular Chondrocytes for Ear Reconstruction

Advanced Functional Materials, EarlyView.
Despite over three decades of research, no tissue‐engineered solution for auricular reconstruction in microtia patients has reached clinical translation. The key challenge lies in generating functional elastic cartilage ex vivo. Here, we integrate synergistic cell‐biomaterial strategies to engineer auricular grafts with mechanical and histological ...

Coherence-Based Robust Analysis of Basis Pursuit De-Noising and Beyond

IEEE Access, 2019
In this paper, by means of the powerful coherence tool, we first establish a coherence-based performance guarantee for the basis pursuit de-noising (BPDN) to recover the signals corrupted with the `2norm bounded noise, and then extend these theoretical ...

Sorted $$L_1/L_2$$ Minimization for Sparse Signal Recovery

Journal of Scientific Computing
This paper introduces a novel approach for recovering sparse signals using sorted L1/L2 minimization. The proposed method assigns higher weights to indices with smaller absolute values and lower weights to larger values, effectively preserving the most significant contributions to the signal while promoting sparsity.

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control

Advanced Functional Materials, EarlyView.
A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

Bio‐Inspired Multimodal Hardware Front‐End Enabled by 2D Floating‐Gate Memory for UAV Perception

Advanced Functional Materials, EarlyView.
A MoS2/h‐BN /graphene floating‐gate memory underpins a bio‐inspired multimodal front end that integrates visual, inertial, and airflow cues. A 4 × 4 FG memory array encodes temporal intensity differences, while IMU‐ and airflow‐driven threshold modulation suppresses self‐motion artifacts, enabling fast, low‐power, robust autonomous UAV tracking and ...

A Comparative Study of Compressive Sensing Techniques for Sparse Signal Recovery in Massive MIMO

Journal of Communications Software and Systems
Massive multiple-input multiple-output (MIMO) systems are essential for next-generation wireless networks, but their high-dimensional signal processing demands pose challenges, particularly in sparse signal recovery.

Stable Recovery of Signals From Highly Corrupted Measurements

IEEE Access, 2018
In this paper, we consider the stable recovery of sparse or proximately sparse signals x ∈ ℝn from highly corrupted linear measurements b = Ax + f + e, where f ∈ ℝm is a sparse error vector whose nonzero entries may be ...

Sparse Vector Distributions and Recovery from Compressed Sensing

, 2011
It is well known that the performance of sparse vector recovery algorithms from compressive measurements can depend on the distribution underlying the non-zero elements of a sparse vector.

A Simple Gaussian Measurement Bound for Exact Recovery of Block-Sparse Signals

Discrete Dynamics in Nature and Society, 2014
We present a probabilistic analysis on conditions of the exact recovery of block-sparse signals whose nonzero elements appear in fixed blocks. We mainly derive a simple lower bound on the necessary number of Gaussian measurements for exact recovery of ...
