Published in 2017 at "Geophysical Research Letters"

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.

Published in 2017 at "Journal of Geophysical Research"

DOI: 10.1002/2017jb014164

Abstract: A continuous active source seismic monitoring (CASSM) dataset was collected with crosswell geometry during CO2 injection at the Frio-II brine pilot, near Liberty, TX. Previous studies have shown that spatio-temporal changes in the P-wave first… read more here.

Published in 2017 at "Journal of Geophysical Research"

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.

Published in 2024 at "Advanced Functional Materials"

DOI: 10.1002/adfm.202408110

Abstract: The remarkable ability of natural proteins to conduct electricity in the dry state over long distances remains largely inexplicable despite intensive research. In some cases, a (weakly) exponential length‐attenuation, as in off‐resonant tunneling transport, extends… read more here.

Published in 2025 at "Advanced Materials"

DOI: 10.1002/adma.202501330

Abstract: π‐conjugated metal‐organic frameworks (MOFs) have emerged as promising candidates for electromagnetic wave (EMW) absorption, owning to their high conductivity and versatile structural tunability. Nevertheless, the effective control over their dielectric properties is a challenge. Herein,… read more here.

Published in 2025 at "Advanced science"

DOI: 10.1002/advs.202516448

Abstract: Live attenuated influenza vaccines (LAIVs) can elicit broad immunity, but rational attenuation strategies are limited. PR8rp, a prototype influenza A virus with five segments extensively reprogrammed to use the least-preferred synonymous codons is generated, introducing… read more here.

Published in 2020 at "Human Brain Mapping"

DOI: 10.1002/hbm.25039

Abstract: Abstract PET attenuation correction (AC) on systems lacking CT/transmission scanning, such as dedicated brain PET scanners and hybrid PET/MRI, is challenging. Direct AC in image‐space, wherein PET images corrected for attenuation and scatter are synthesized… read more here.

Published in 2025 at "Journal of Biophotonics"

DOI: 10.1002/jbio.202500212

Abstract: Brain development is a highly regulated process with significant morphological and functional transformations during early embryogenesis. Here, we quantified the optical attenuation coefficient (OAC) during murine embryonic brain development with a focus on crucial areas,… read more here.

Published in 2018 at "Journal of Bone and Mineral Research"

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.

Published in 2017 at "Journal of Orthopaedic Research"

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.
