DOI: 10.1002/2017gl072507
Abstract: Coda wave attenuation imaging is able to detect fluid/melt accumulation and ancient magmatic bodies in volcanoes. Here we use recently developed space-weighting sensitivity functions to invert for the spatial distributions of multifrequency coda wave attenuation… read more here.

DOI: 10.1002/2017jc012978
Abstract: Wave attenuation from two field experiments in the ice-covered Southern Ocean is examined. Instead of monotonically increasing with shorter waves, the measured apparent attenuation rate peaks at an intermediate wave period. This ‘rollover' phenomenon has… read more here.

DOI: 10.1002/jbmr.3383
Abstract: We sought to determine if vertebral trabecular attenuation values measured on routine body computed tomography (CT) scans obtained for a variety of unrelated indications can predict future osteoporotic fractures at multiple skeletal sites. For this… read more here.

DOI: 10.1002/jor.23337
Abstract: The biochemical and histopathological techniques used to investigate meniscal content and structure are destructive and time‐consuming. Therefore, this study evaluated whether contrast‐enhanced computed tomography (CECT) attenuation and contrast agent flux using the iodinated contrast agents… read more here.
