Detailed mapping of prostate carcinoma foci
Cancer, 2000Prostate carcinoma exhibits considerable anatomic heterogeneity. Detailed characterization of prostate carcinoma distribution could lead to improved detection procedures and biopsy strategies. We mapped all 607 tumor foci from 180 serially sectioned whole mount radical prostatectomy specimens and used a computer algorithm to plot and summarize the ...

Instant convolution shadows for volumetric detail mapping
ACM Transactions on Graphics, 2013In this article, we present a method for rendering dynamic scenes featuring translucent procedural volumetric detail with all-frequency soft shadows being cast from objects residing inside the view frustum. Our approach is based on an approximation of physically correct shadows from distant Gaussian area light sources positioned behind the view plane ...

Level of Detail Control for Texture on 3D Maps
11th International Conference on Parallel and Distributed Systems (ICPADS'05), 2006This paper proposes a method to control texture resolution levels for large-scale 3D maps of urban areas. Recently, performance of computers has been developed rapidly, but it is still hard to directly handle the large-scale 3D maps on PCs, because of its high requirement for hardware capability.

Venus: Detailed Mapping of Maxwell Montes Region
Science, 1986From October 1983 to July 1984, the north hemisphere of Venus, from latitude 30° to latitude 90°, was mapped by means of the radar imagers and altimeters of the spacecraft Venera 15 and Venera 16. This report presents the results of the radar mapping of the Maxwell Montes region, one of the most interesting features of Venus' surface.

Adaptive Hierarchical Mesh Detail Mapping and Deformation
2019In this work, we present a new method for controlled deformation and detail addition to 3d shapes represented as variable resolution meshes. The input data is a surface with arbitrary genus, represented by a polygonal mesh, and a set of parameters for edition control: positional information, the level of resolution, mesh features and direction of ...

The quest to map STIM1 activation in granular detail
Cell CalciumThe conformational change in STIM1 that communicates sensing of ER calcium-store depletion from the STIM ER-luminal domain to the STIM cytoplasmic region and ultimately to ORAI channels in the plasma membrane is broadly understood. However, the structural basis for the STIM luminal-domain dimerization that drives the conformational change has proven ...

Detailed Soil Maps for Experimental Farms
Outlook on Agriculture, 1957Soils vary so much in type, even within a single field, that it is often difficult on agricultural research stations to select suitable sites for field trials. One answer to this problem is to make a detailed soil map of the experimental area, using factors of agronomic importance based on the soil profile in deciding categories for mapping.
