It has recently become possible to simulate aneurysmal blood flow dynamics in a patient-specific manner via the coupling of three-dimensional (3-D) X-ray angiography and computational fluid (CFD). Before such image-based CFD models can be used predictive capacity, however, it must shown that they indeed reproduce vivo hemodynamic environment. Motivated by fact there are currently no techniques for adequately measuring complex velocity fields vivo, this paper we describe how cine angiograms...
Abstract We describe a theoretical and numerical framework that has been developed to investigate the compatibility of ICE‐6G_C reconstruction glaciation histories Greenland Antarctic ice sheets with latest understanding physics. The produced solely on basis theory glacial isostatic adjustment (GIA) process, it remained an issue as whether such reconstructions time‐dependent thickness variations grounded continental were compatible physics‐based mechanical considerations. Our analyses focus...
Abstract Analyses of glacial isostatic adjustment (GIA) and deglacial relative sea‐level (RSL) change in the Russian Arctic deliver important insights into Earth's viscosity structure deglaciation history Eurasian ice sheet complex. Here, we validate 1D GIA models ICE‐6G_C (VM5a) ICE‐7G_NA (VM7) select new 3D against a quality‐controlled RSL database >500 data points from 24 regions. Both correspond to along southern coast Barents Sea Franz Josef Land ∼11 ka BP present but show notable...
We analyze the effects of nudging 100 kyr numerical simulations Laurentide and Fennoscandian ice sheets toward glacial isostatic adjustment‐based (GIA‐based) ICE‐6G_C reconstruction most recent age cycle. Starting with physics approximations PISM sheet model SeaRISE simulation protocols, we incorporate at characteristic time scales, τ f , through anomalous mass balance terms in conservation equation. As should be expected, these balances exhibit physically unrealistic details arising from...
Abstract The possibility that Heinrich event 1 (H1), which occurred during the most recent deglaciation of current ice age, may have been both triggered and subsequently continuously forced by tides, is investigated. For purpose this investigation, a discontinuous Galerkin method employed to solve shallow water tidal equations on sphere using nonuniform icosahedral grid enable high resolution Hudson Strait region was locus stream instability caused H1. Since events are known involved, for if...
Abstract The ocean floor sedimentological signature of Heinrich event 3 (H3) is markedly different from that other events are known to have originated in Hudson Strait. It has therefore been suggested the H3 contribution iceberg flux may delivered by ice streams located eastern sector North Atlantic, Fennoscandian or British Isles sheets. To investigate this possibility and whether instability involved tidally induced, as seems case for H1, we consider several Atlantic possibilities: a...

Summary Antarctica has been proposed as a significant source of the meltwater that entered oceans during Meltwater Pulse 1B (MWP1B) approximately 11,500 years ago. Support for this scenario provided by evidence deep fjords coastal Antarctica, which were heavily glaciated at maximum glaciation, deglaciated time. Further support was observation inter-hemispheric sea level teleconnection associated with southern hemisphere deglaciation time an explanation highly non-monotonic relative histories...
