Blind Orthogonal Least Squares based Compressive Spectrum Sensing [article]

Liyang Lu, Wenbo Xu, Yue Wang, Siye Wang
2022 arXiv   pre-print
Compressive spectrum sensing (CSS) has been widely studied in wideband cognitive radios, benefiting from the reduction of sampling rate via compressive sensing (CS) technology. However, the sensing performance of most existing CSS excessively relies on the prior information such as spectrum sparsity or noise variance. Thus, a key challenge in practical CSS is how to work effectively even in the absence of such information. In this paper, we propose a blind orthogonal least squares based CSS

Specifically, we develop a novel blind stopping rule for the OLS algorithm based on its probabilistic recovery condition. This innovative rule gets rid of the need of the spectrum sparsity or noise information, but only requires the computational-feasible mutual incoherence property of the given measurement matrix. Our theoretical analysis indicates that the signal-to-noise ratio required by the proposed B-OLS-CSS for achieving a certain sensing accuracy is relaxed than that by the benchmark CSS using the OMP algorithm, which is verified by extensive simulation results.

An Efficient Extended Targets Detection Framework Based on Sampling and Spatio-Temporal Detection

Bo Yan, Na Xu, Wenbo Zhao, Muqing Li, Luping Xu
2019 Sensors  
Excellent performance, real-time and low memory requirement are three vital requirements for target detection in high resolution marine radar system. Unfortunately, many current state-of-the-art methods merely achieve excellent performance when coping with highly complex scenes. In fact, a common problem is that real-time processing, low memory requirement and remarkable detection ability are difficult to coordinate. To address this issue, we propose a novel detection framework which bases its

Sampling-based coarse detection is designed to guarantee the real-time processing and low memory requirements by locating the area where targets may exist in advance. Different from former detection methods, multi-scan video data are utilized. In the stage of fine detection, the candidate areas are grouped into three categories: single target, dense targets and sea clutter. Different approaches for processing the different categories are implemented to achieve excellent performance. The superiority of the proposed framework beyond state-of-the-art baselines is well substantiated in this work. Low memory requirement of the proposed framework was verified by theoretical analysis. Real-time processing capability was verified by the video data of two real scenarios. Synthetic data were tested to show the improvement in tracking performance by using the proposed detection framework.

Artificial intelligence-based approaches for COVID-19 patient management

Lan Lan, Wenbo Sun, Dan Xu, Minhua Yu, Feng Xiao, Huijuan Hu, Haibo Xu, Xinghuan Wang
2021 Intelligent Medicine  
During the highly infectious pandemic of coronavirus disease 2019 (COVID-19), artificial intelligence (AI) has provided support in addressing challenges and accelerating achievements in controlling this public health crisis. It has been applied in fields varying from outbreak forecasting to patient management and drug/vaccine development. In this paper, we specifically review the current status of AI-based approaches for patient management. Limitations and challenges still exist, and further needs are highlighted.

High 18F-fluorodeoxyglucose uptake in cardiac tumor

Ying Liu, Hua Pang, Lu Xu, Qiong Liu, Wenbo Li
2016 Medicine  
Cardiac tumors, especially malignant, are rare but aggressive tumors that mostly arise from the mesenchymal cells and represent a challenging diagnosis for clinicians. Recently, fluorine-18-fluorodiography positron emission tomography and computed tomography ( 18 F-FDG PET/CT) is an increasingly popular new technique with diagnosis of tumor. Methods: We report a case of a right heart tumor showing intense uptake of 18 F-fluorodeoxyglucose ( 18 F-FDG) on position emission tomography/computed

Results: The maximal standardized uptake values (SUV max ) for the cardiac and metastatic lesion were 17.2 and 12.9, respectively. Conclusion: 18 F-FDG PET/CT imaging, which enables both morphological characterization and visualization of tumor metabolism, may be an effective and feasible noninvasive method for the diagnosis of malignant cardiac tumors. Abbreviations: 18 F-FDG PET/CT = fluorine-18-fluorodeoxyglucose position emission tomography and computed tomography, CT = computed tomography, CTN = computerized tomography number, MRI = magnetic resonance imaging, SUV max = maximum standardized uptake value.

Coordinated Aerial-Ground Robot Exploration via Monte-Carlo View Quality Rendering [article]

Di Deng, Zhefan Xu, Wenbo Zhao, Kenji Shimada
2020 arXiv   pre-print
We present a framework for a ground-aerial robotic team to explore large, unstructured, and unknown environments. In such exploration problems, the effectiveness of existing exploration-boosting heuristics often scales poorly with the environments' size and complexity. This work proposes a novel framework combining incremental frontier distribution, goal selection with Monte-Carlo view quality rendering, and an automatic-differentiable information gain measure to improve exploration efficiency.

Due to the preeminent work of the real-time specification for Java (RTSJ), Java is increasingly expected to become the leading programming language in real-time systems. To provide a Java platform suitable for real-time applications, a Java processor which can execute Java bytecode is directly proposed in this paper.

Recombination analysis of Human mastadenovirus C whole genomes

Pierre Rivailler, Naiying Mao, Zhen Zhu, Wenbo Xu
2019 Scientific Reports  
This study aims at analyzing all publicly available HAdV-C whole genome sequences (WGSs) and describes the genetic relationships between these genomes as well as identifies potential hotspots for recombination throughout the viral genome. In addition to the 4 prototypical genomic sequences, this analysis identified 20 HAdV-C WGSs which should be relevant for future recombination analysis of HAdV-C. This report confirmed the recombinogenic property of HAdV-C genomes and identified two main

Finally, it highlighted the need for a surveillance of HAdVs in order to detect novel recombinant types that might represent health risks and develop possible prevention measures. Genetic analyses of recombination between recently collected HAdV-Cs and the assessment of their potential virulence are necessary steps towards the establishment of a surveillance of HAdVs in the future.
