Impact of the Water Reservoir and River Engineering Structures on Longitudinal and Transverse (Dis)connectivity Associated With Sediment Transfer

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Human impact in the form of reservoir construction and river regulation downstream of reservoirs, is causing irreversible alterations to hillslope and river channel connectivity in river catchments. This disruption in the dynamic equilibrium of the river is attributed to sediment accumulation upstream of the reservoir's dam, limited sediment ...

A virtual imaging study of microcalcification detection performance in digital breast tomosynthesis: Patients versus 3D textured phantoms

open access: yesMedical Physics, EarlyView.
Abstract Background Clinical studies to evaluate the performance of new imaging devices require the collection of patient data. Virtual methods present a potential alternative in which patient‐simulating phantoms are used instead. Purpose This work uses a virtual imaging technique to examine the extent to which human observer microcalcification ...
