Molecular Probe-Guided Surface-Enhanced Raman Scattering Sensing Interfaces and Multiview Feature Fusion for Interpretable Serum Fingerprinting in Prostate Disease Classification

Lin Xu, Maozhong Fu, Wei Qiao, Junqi Huang et autres

Accurate discrimination between prostate cancer (PCa) and benign prostatic hyperplasia (BPH) remains clinically challenging. Here, we developed a multiprobe serum surface-enhanced Raman scattering (SERS) sensing platform comprising Ag NPs (Ag), 4-mercaptobenzoic acid (MBA)@Ag, 4-mercaptophenylboronic acid (MPBA)@Ag, and 4-aminothiophenol (ATP)@Ag, together with a …

Fast and Accurate Angle Estimation for MIMO Radar With a Virtual Nonrectangular Array

Maozhong Fu, Yishan Ye, J. Tang, Zhenmiao Deng

Modern radar systems commonly utilize multiple-input multiple-output (MIMO) architectures, which often result in non-rectangular virtual antenna arrays. For these non-rectangular configurations, conventional angle estimation methods based on uniform linear array (ULA) are suboptimal as they discard partial spatial information. Furthermore, subspace-based and …

Angle Estimation for Range-Spread Targets Based on Scatterer Energy Focusing

Zekai Huang, Ping Jiang, Maozhong Fu, Zhenmiao Deng

Wideband radar is becoming increasingly significant in modern radar systems. However, traditional monopulse angle estimation techniques are not suitable for wideband targets exhibiting range extension effects. To address this, we explore the angle estimation problem for wideband Linear Frequency-Modulated (LFM) signals and …

Detection of Fast-Moving and Accelerating Target Using Linear Frequency-Modulated Continuous-Wave Radars

Maozhong Fu, Rui Zhang, Jun Tang, Zhenmiao Deng

The challenges of range migration (RM) and Doppler frequency migration (DFM) are inherent in detecting fast-moving and accelerating targets using linear frequency-modulated continuous-wave (LFMCW) radar. Through the analysis of LFMCW echo components, it becomes evident that RM and DFM are primarily caused …

Genetic Parameters and Genome-Wide Association Studies for Body Size Traits of Shuxuan Cattle in China

Wei Min Wang, Maozhong Fu, Donghui Fang, Yi SHI et autres

In domestic cattle, the body size traits have important implications in terms of breed characteristics and production performance. Shuxuan cattle is a dual-purpose breed mainly raised in Sichuan province, China, for which we have known less about the genetic parameters and underlying …

High-Resolution and Accurate RV Map Estimation by Spare Bayesian Learning

Maozhong Fu, Yuhan Li, Zhenmiao Deng, Haixin Sun et autres

Range-velocity (RV) map (also called the range-Doppler map) is used in radar to detect targets and estimate the range and velocity of the targets. The conventional range-Doppler processing has its limits in attaining a high-resolution RV map with few samples. Moreover, the …
