A Joint Audio-Visual Approach to Audio Localization [PDF]

open access: yes, 2015
Localization of audio sources is an important research problem, e.g.,to facilitate noise reduction. In the recent years, the problem hasbeen tackled using distributed microphone arrays (DMA).

Research progress on the depth of anesthesia monitoring based on the electroencephalogram

open access: yesIbrain, Volume 11, Issue 1, Page 32-43, Spring 2025.
Electroencephalogram (EEG) can noninvasive, continuous, and real‐time monitor the state of brain electrical activity, and the monitoring of EEG can reflect changes in the depth of anesthesia (DOA). The development of artificial intelligence can enable anesthesiologists to extract, analyze, and quantify DOA from complex EEG data.

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

open access: yesWildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Multiple Parameter Estimation With Quantized Channel Output

open access: yes, 2010
We present a general problem formulation for optimal parameter estimation based on quantized observations, with application to antenna array communication and processing (channel estimation, time-of-arrival (TOA) and direction-of-arrival (DOA) estimation)

Gut Microbiome Dysbiosis is Associated With Human T‐Lymphotropic Virus Type 1 (HTLV‐1) Infection and Disease Progression to HTLV‐1‐Associated Myelopathy/Tropical Spastic Paraparesis: A Cross‐Sectional Study

open access: yesSmart Medicine, Volume 5, Issue 1, February 2026.
We provide the first comprehensive analysis of changes in the gut bacteriome at different clinical stages of HTLV‐1 infection. HTLV‐1 infection is associated with a dysbiosis that includes reduced bacterial diversity and an inverted Firmicutes/Bacteroidetes ratio.
