Federated Graph Learning for Low Probability of Detection in Wireless Ad-Hoc Networks

, 2023
Low probability of detection (LPD) has recently emerged as a means to enhance the privacy and security of wireless networks. Unlike existing wireless security techniques, LPD measures aim to conceal the entire existence of wireless communication instead ...

Detection and Direction-of-Arrival Estimation of Weak Spread Spectrum Signals Received with Antenna Array

, 2021
This paper presents a method for the joint detection and direction of arrival (DOA) estimation of low probability of detection (LPD) signals. The proposed approach is based on using the antenna array to receive spread-spectrum signals hidden below the ...

Ensemble of adaboost cascades of 3L-LBPs classifiers for license plates detection with low quality images

, 2018
Due to the plate formats and multiform outdoor illumination conditions during the image acquisition phase, it is challenging to find effective license plate detection (LPD) method. This paper aims to develop a new detection method for identifying vehicle

Low Probability of Intercept/Detect (LPI/LPD) Secure Communications Using Antenna Arrays Employing Rapid Sidelobe Time Modulation

IEEE Transactions on Antennas and Propagation
We present an electronically-reconfigurable antenna array offering low probability of intercept/detect (LPI/LPD) and secure communications capabilities simultaneously at the physical layer. This antenna array is designed to provide rapidly time-varying sidelobes and a stationary main lobe. By performing rapid sidelobe time modulation (SLTM), the signal

Extracellular vesicle proteomics identifies novel blood biomarkers for the early diagnosis of status epilepticus. [PDF]

Epilepsia
Abstract Objective This study was undertaken to identify novel blood‐based biomarkers associated with the early diagnosis of status epilepticus (SE) by exploring proteomic alterations in plasma extracellular vesicles (EVs). Methods We conducted an observational and prospective study in a two‐phase design: a discovery proteomic analysis of plasma EVs ...

Continuous Versus Short EEG After Ischemic Stroke: What cEEG Adds for Detecting Abnormalities and Predicting Post‐Stroke Epilepsy

Annals of Neurology, EarlyView.
Objective The objective of this study was to quantify incremental diagnostic yield and prognostic value of continuous electroencephalography (cEEG; ≥12 hours) versus a 60‐minute short electroencephalography (sEEG) in predicting post‐stroke epilepsy (PSE) in patients without acute symptomatic seizures.

Using large language models to analyze political texts through natural language understanding

American Journal of Political Science, EarlyView.
Abstract Large language models (LLMs) offer scalable alternatives to human experts when analyzing political texts for meaning, using natural language understanding (NLU). Qualitative NLU methods relying on human experts are severely limited by cost and scalability.

Clinical features and prognostic factors of adult systemic chronic active EBV disease: A retrospective analysis in Japan

British Journal of Haematology, EarlyView.
ALT and ferritin were adverse prognostic markers enabling risk stratification in adult systemic chronic active Epstein–Barr virus disease (sCAEBV). In hydroa vacciniforme lymphoproliferative disorder (HV‐LPD), Epstein–Barr virus (EBV) infection of CD4+ cells was associated with progression to sCAEBV.

Performance Metrics for Low Probability of Detection in Cooperative Communication Networks

, 2016
This paper proposes two metrics for evaluating the low probability of detection (LPD) performance in cooperative wireless communication networks. One metric is the distance ration between the minimum range of all the interceptor-relay/transmitter pairs ...
