We present recent results from the design of the GFDL ocean circulation model for the Cedar multicluster architecture. The model simulates the basic aspects of largescale, baroclinic ocean circulation, including treatment of irregular bottom topography. We concentrate on several modifications and versions of the code that are designed to exploit the memory and computational hierarchy of Cedar, ...

The motion of an incompressible fluid confined to a shallow basin with a slightly varying bottom topography is considered. Coriolis force, surface wind and pressure stresses, together with bottom and lateral friction stresses are taken into account. We introduce appropriate scalings into a three-dimensional anisotropic eddy viscosity model; after averaging on the vertical direction and consider...

Digital elevation models of Antarctic bed topography are smoothed and interpolated onto lowresolution ( > 1 km) grids as current observed topography data are generally sparsely and unevenly sampled. This issue has potential implications for numerical simulations of ice-sheet dynamics, especially in regions prone to instability where detailed knowledge of the topography, including fine-scale rou...

Biodiversity monitoring is increasingly being bolstered with high resolution data derived from remote sensing such as LIDAR (Light Detection and Ranging). We derived a series of topographical variables, including slope, azimuth, ground curvature and flow accumulation from LIDAR images and compared these to captures of female carabids in pitfall traps in Eastern boreal mixedwood forests. We deve...

The elastic contact between two computer generated isotropic rough surfaces is studied. First the surface topography parameters including the asperity density, mean summit radius, and standard deviation of asperity heights of the equivalent rough surface are determined using an 8-nearest neighbor summit identification scheme. Second, many cross sections of the equivalent rough surface are trace...

The cerebral cortex communicates with the cerebellum via polysynaptic circuits. Separate regions of the cerebellum are connected to distinct cerebral areas, forming a complex topography. In this study we explored the organization of cerebrocerebellar circuits in the human using resting-state functional connectivity MRI (fcMRI). Data from 1,000 subjects were registered using nonlinear deformatio...

Results of an observational, descriptive study quantifying topography characteristics of twenty first generation electronic nicotine delivery system users in their natural environment for a one week observation period are presented. The study quantifies inter-participant variation in puffing topography between users and the intra-participant variation for each user observed during one week of u...

purpose: to evaluate topographic corneal changes in relatives of patients with keratoconus (kcn). methods: this study was performed on 300 eyes of 150 relatives of 45 kcn patients. complete slit lamp examination, refraction, and corneal topography was performed on all eyes. the topographic indices for diagnosis of keratoconus was based on rabinowitz criteria. results: the study included 84 (56%...
