Research on Acoustic Recognition of Underwater Targets based on the Principle of Sound Absorption

open access: yesHighlights in Science, Engineering and Technology, 2023
Due to the concealment of underwater engineering, the detection and monitoring of hydraulic structure construction is often more complicated and difficult than surface engineering. Cofferdam construction inspection and settlement construction quality inspection, especially to ensure the accuracy and efficiency of inspection in complex environments ...

The Effects of Noise on the Juvenile Life Stage of Crustaceans: Behavioral, Cellular, and Molecular Responses in Procambarus clarkii

open access: yesIntegrative Zoology, EarlyView.
Juvenile Procambarus clarkii exposed to noise exhibited behavioral changes, shifts in enzymatic activity, and altered expression of stress and immune genes. The findings highlight the sensitivity of invertebrate juveniles to anthropogenic acoustic pollution.

Early‐life temperature drives recruitment success in Eurasian perch (Perca fluviatilis) populations

open access: yesJournal of Fish Biology, EarlyView.
Abstract Interannual fluctuations in the abundance of young‐of‐the‐year (YOY) European perch (Perca fluviatilis) were studied in two large French peri‐alpine lakes using a 12‐year dataset of late summer hydroacoustic surveys. Previous research has highlighted the importance of temperature.

Empowering Climate Resilience in La Margarita, Salinas, Puerto Rico: Lessons Learned From the Co‐Production of NASA Earth Observation Data Applications for Environmental Justice

open access: yesCommunity Science, Volume 5, Issue 3, September 2026.
Abstract Confronted by daunting environmental risks and disasters, communities in the Caribbean–particularly those in economically disenfranchised areas–face disproportionate consequences from climate change, such as hazardous air and water quality.

Automatic Workout Mortgage and Housing Consumption Choice

open access: yesInternational Review of Finance, Volume 26, Issue 3, September 2026.
ABSTRACT This paper further develops the Automatic Workout Mortgage (AWM) which embeds an insurance put option to reduce negative equity, systemic risk and promote economic recovery. We introduce a mathematical model showing that AWM raises household utility and increases housing demand.

Fatigue and Cognitive Impairment in Adults With Primary Sclerosing Cholangitis: Results From Concept Elicitation Interviews

open access: yesLiver International, Volume 46, Issue 9, September 2026.
ABSTRACT Background and Aims To understand the experience of fatigue and cognitive impairment in adults with symptomatic primary sclerosing cholangitis (PSC) as an essential first step towards developing PSC‐specific symptom measures. Methods Purposeful sampling was used to identify 17 symptomatic adults from the PSC Symptom Assessment Project who met ...

A three-dimensional bistatic reverberation model of underwater explosion by interface scattering at variable sound speeds

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2019
Underwater reverberation is a main limitation of the sonar performance and thereby the reverberation level estimation becomes crucial. In this study, based on the Lambert law and ray theory, a model for predicting 3D bistatic reverberation performance by
