The Acoustic Index User's Guide: A practical manual for defining, generating and understanding current and future acoustic indices

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 6, Page 1040-1050, June 2025.
Abstract Ecoacoustics, the study of environmental sound, is a rapidly growing discipline offering ecological insights at scales ranging from individual organisms to whole ecosystems. Substantial methodological developments over the last 15 years have streamlined extraction of ecological information from audio recordings.

Analyzing Baryon Acoustic Oscillations in Sparse Spectroscopic Samples via Cross-Correlation with Dense Photometry

open access: yes, 2017
We develop a formalism for measuring the cosmological distance scale from baryon acoustic oscillations (BAO) using the cross-correlation of a sparse redshift survey with a denser photometric sample. This reduces the shot noise that would otherwise affect

Hybrid Levenberg–Marquardt and LSBoosting Ensemble Algorithms for Optimal Signal Attenuation Modeling and Coverage Analysis

open access: yesInternational Journal of Communication Systems, Volume 38, Issue 8, 25 May 2025.
ABSTRACT This paper proposes and engages the Levenberg–Marquardt algorithm method via regression to optimally model and predict real‐time signal strength values acquired via telecom software investigation tools in LTE cellular networks. To further improve the Levenberg–Marquardt method, which is sometimes prone to parameter evaporation on high ...

Worldwide Soundscapes: A Synthesis of Passive Acoustic Monitoring Across Realms

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 5, May 2025.
ABSTRACT Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM ...
