Published in 2017 at "Geophysical Research Letters"

DOI: 10.1002/2017gl075342

Abstract: In passive source seismology, seismic interferometry typically refers to the cross-correlation of ambient noise to construct an estimate of the Green's function between sensors. The presence of persistent natural and/or anthropogenic sources can bias or… read more here.

Published in 2017 at "Tectonics"

DOI: 10.1002/2017tc004468

Abstract: We present a new approach for evaluating existing crustal models using ambient noise datasets and its associated uncertainties. We use a transdimensional hierarchical Bayesian inversion (THBI) approach to invert ambient noise surface wave phase dispersion… read more here.

Published in 2022 at "Journal of Applied Clinical Medical Physics"

DOI: 10.1002/acm2.13870

Abstract: Abstract Purpose This work investigates the impact of tissue‐equivalent attenuator choice on measured signal‐to‐noise ratio (SNR) for automatic exposure control (AEC) performance evaluation in digital mammography. It also investigates how the SNR changes for each… read more here.

Published in 2022 at "American Journal of Primatology"

DOI: 10.1002/ajp.23421

Abstract: Noise can be a known stressor but our understanding of its effects on animals living in zoo environments remains limited. Although exposure to loud, chronic noise may be expected to negatively impact welfare, providing access… read more here.

Published in 2022 at "Developmental psychobiology"

DOI: 10.1002/dev.22325

Abstract: The home auditory environment influences the development of early language abilities, and excessive noise exposure is increasingly linked with deficits in language and reading scores in children. However, fewer studies have considered the role of… read more here.
