Sensors, Vol 17, Iss 6, p 1315 (2017)
This paper presents a joint estimation method of source range and depth using a bottom-deployed vertical line array (VLA). The method utilizes the information on the arrival angle of direct (D) path in space domain and the interference characteristic

Pleckstrin homology (PH) domain leucine-rich repeat protein phosphatase 2 (PHLPP2) is a critical regulator of cellular homeostasis and acts as a tumor suppressor in multiple human cancers. However, its exact biological function in colorectal cancer (

A previous study established a method for localizing low-frequency acoustic sources in the near field using a passive synthetic aperture method [Lei et al., 2015]. Sound fields sampled at different positions (sub-apertures) and times are synthesized

In this study, we propose a localization method based on multipath time-delay difference (MTD). We extract the time-delay difference of the direct and sea surface-reflected sound rays by the signal from hydrophones in deep sea to establish the MTD ma

Many research results show that ocean ambient noise and wind speed are highly relevant, and the surface wind speed can be effectively inverted using ocean noise data. In most deep-sea cases, the ambient noise of medium frequency is mainly determined
