Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Navigator‐Based Slice Tracking for Multiband Accelerated Liver DWI
ABSTRACT Purpose Clinical liver diffusion‐weighted imaging (DWI) suffers from long measurement time and respiratory motion. In this study, we employ a navigator‐based slice tracking technique (NAV) to prospectively compensate for respiratory motion in multiband (MB) accelerated liver DWI.

ABSTRACT Purpose Phosphocreatine (PCr) is an essential marker of muscle metabolism, and accurate quantification of its (fs) and its exchange rate (ksw) is essential for diagnosing various muscular and neuromuscular diseases. Although chemical exchange saturation transfer (CEST) MRI can detect the saturation transfer effect from PCr, quantification of ...

The photochemistry of ethyl 2‐diazo‐3,3,3‐trifluoropropanoate shows that its excited singlet state undergoes internal conversion, carbene formation, and diazirine formation. The resulting singlet carbene reacts through solvent‐dependent pathways, forming ylides in methanol and acetonitrile or a C–Cl insertion product in chloroform.

Extending Māori Concepts in Secondary School Geography
ABSTRACT Secondary school geography brings together tāngata (people) and whenua (land), the central concepts of te ao Māori (the Māori world). Therefore, geography is ideally placed to respond to calls for mātauranga Māori (Māori knowledge) to gain “equal status” with Western knowledge.
