GEOMETRY OF QUANTUM VORTICES AND LINK INVARIANTS

International Journal of Modern Physics B, 1992
We report on recent and ongoing research in the context of the geometric approach to quantum vortices and link invariants (via the Marsden-Weinstein theory and Chen’s iterated path integrals).

Solvation of Proteins: Linking Thermodynamics to Geometry

Physical Review Letters, 2007
We calculate the solvation free energy of proteins in the tube model of Banavar and Maritan [Rev. Mod. Phys. 75, 23 (2003)10.1103/RevModPhys.75.23] using morphological thermodynamics which is based on Hadwiger's theorem of integral geometry. Thereby we extend recent results by Snir and Kamien [Science 307, 1067 (2005)10.1126/science.1106243] to hard ...

Geometry Links the Two Spheres

The Arithmetic Teacher, 1986
When the educators of today were growing up, little information was available about the brain and its relationship to the acquisition of knowledge. Recent research has hown that the brain functions a two hemispheres, a right side and a left side. Each side influence our learning and emotions and provides the foundation for complementary but different ...

Some links between turtle geometry and analytic geometry

International Journal of Mathematical Education in Science and Technology, 1985
The computer language LOGO facilitates the teaching of analytic geometry and calculus from the notion of curvature, through its ‘turtle geometry’ facility [2]. We provide some theoretical basis for finding turtle geometry equivalents of familiar curves in analytic geometry, and vice versa, by some simple methods which apparently have not been noticed ...

Multiple Coordination Geometries Supported by Methylene-Linked Guanidines

Inorganic Chemistry, 2004
The methylene-linked bicyclic guanidine based on the 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidine (hppH) framework provides a versatile platform able to support trigonal-planar, tetrahedral, and square-planar metal centers.

Linking Structure and Parametric Geometry

Architectural Design, 2013
AbstractThe Karamba plug‐in developed by Clemens Preisinger in collaboration with Bollinger + Grohmann Engineers has been developed to predict the behaviour of structures under external loads. Intended to be used by architects rather than being solely confined to an engineering setting, it enables a seamless flow of data between structural and ...

Diverse calving patterns linked to glacier geometry

Nature Geoscience, 2013
Iceberg calving—implicated in the retreat of ice shelves—is a complex process constrained by few observations. Numerical simulations suggest that the pattern of iceberg calving is controlled by the geometry of the glacier, and that regions of Greenland and Antarctica may be particularly vulnerable to catastrophic calving-driven retreat.
