Bridging the Gap Between Human Toxicology and Ecotoxicology Under One Health Perspective by a Cross‐Species Adverse Outcome Pathway Network for Reproductive Toxicity

Environmental Toxicology and Chemistry, EarlyView.
Cross‐species extrapolation of adverse outcome pathway network on reproductive toxicity under the One Health perspective using new approach methodologies. AOP = adverse outcome pathway. Abstract Although ecotoxicological and toxicological risk assessments are performed separately from each other, recent efforts have been made in both disciplines to ...

A survey of localization in wireless sensor network [PDF]

, 2012
Localization is one of the key techniques in wireless sensor network. The location estimation methods can be classified into target/source localization and node self-localization. In target localization, we mainly introduce the energy-based method.

The Location of Partial Discharge Sources Inside Power Transformers Based on TDOA Database With UHF Sensors

IEEE Access, 2019
This paper proposes a new method to locate the partial discharge (PD) sources inside the high-voltage power transformers with ultra-high frequency (UHF) sensors, based on the time difference of arrival (TDOA) database.

Prioritising research on endocrine disruption in the marine environment: a global perspective

Biological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Beamforming Design for Joint Localization and Data Transmission in Distributed Antenna System

, 2014
A distributed antenna system is studied whose goal is to provide data communication and positioning functionalities to Mobile Stations (MSs). Each MS receives data from a number of Base Stations (BSs), and uses the received signal not only to extract the

CRLB for joint estimation of TDOA, phase, FDOA, and Doppler rate

The Journal of Engineering, 2019
To avoid decline of FDOA estimation precision caused by relative Doppler companding, Doppler rate has to be considered and estimated jointly with TDOA, phase, and FDOA. However, CRLB of the joint estimation is still unclear.

Near‐Field Acoustic Imaging Using Fiber‐Optic Distributed Acoustic Sensing and Beamforming Techniques

Advanced Science, Volume 13, Issue 6, 30 January 2026.
This work introduces a beamforming‐based method to generate acoustic images from fiber‐optic distributed acoustic sensing (DAS) data. By performing 2D scanning around the sensing fiber, the approach enables near‐field imaging and localization of acoustic sources, even in regions distant from the fiber. A data‐driven DAS channel selection improves image

High-Precision Time Difference of Arrival Estimation Method Based on Phase Measurement

Remote Sensing
In unmanned aerial vehicle (UAV)-based time difference of arrival (TDOA) positioning technique, baselines are limited due to communication constraints. In this case, the accuracy is highly sensitive to the TDOA measurements’ error. This article primarily
