Constrained Weighted Least-Squares Algorithms for 3-D AOA-Based Hybrid Localization

IEEE Open Journal of Signal Processing
Source localization with time-of-arrival (TOA), time-difference-of-arrival (TDOA), time-delay (TD), received-signal-strength (RSS), or angle-of-arrival (AOA) measurements from several spatially distributed sensors is commonly used in practice.

Comparison of Semidistributed Multinode TOA-DOA Fusion Localization and GPS-Aided TOA (DOA) Fusion Localization for MANETs

EURASIP Journal on Advances in Signal Processing, 2008
This paper evaluates the performance of a semidistributed multinode time-of-arrival (TOA) and direction-of-arrival (DOA) fusion localization technique in terms of localization circular error probability (CEP).

Narrowband Interference Mitigation in UWB Systems Utilizing Frequency Dependence of Null Formation in Array Antennas

IEEE Access, 2016
The high precision ranging using ultra wideband (UWB) signals is expected for various applications. However, UWB requires mitigation of narrowband interference (NBI) from other wireless systems.

Surfaceome Reprogramming of Stemsomes Promotes Lung Cancer Targeting via Potentiated Receptor–Ligand Interactions

Advanced Science, EarlyView.
This study presents a surfaceome‐reprogramming strategy for mutation‐independent lung cancer therapy by repurposing dexamethasone to prime mesenchymal stem cell‐derived nanovesicles. The engineered vesicles leverage multi‐valent interactions mediated by upregulated adhesion proteins, EPHA2, and NOTCH3.

Dynamic geo‐hydrogeological monitoring‐driven situational awareness for real‐time floor water inrush risk prediction in deep mining

Deep Underground Science and Engineering, EarlyView.
The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

Transthyretin amyloid cardiomyopathy: Literature review and red‐flag symptom clusters for each cardiology specialty

ESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.
Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...

Prevalence of insulin dysregulation in a sport horse population as determined by traditional and stall‐side testing

Equine Veterinary Journal, EarlyView.
Abstract Background The prevalence of insulin dysregulation (ID) has not been investigated in sport horses. Stall‐side insulin assays offer convenience but need further validation. Objectives To determine the prevalence of and risk factors for ID in a sport horse population using an oral sugar test (OST) and assess agreement between stall‐side and ...

Un enfoque bayesiano para la ubicación de la fuente de emisión acústica modal

Ecomatemático, 2019
Modal Acoustic Emission (MAE) is a branch of Acoustic Emission (AE) with proven capabilities for Structural Health Monitoring (SHM) of plate-like structures. MAE differences from AE in that MAE uses the understanding of the wave propagation to
