Figure 1 Frozen activation map of atrioventricular node reentrant tachycardia (AVNRT), with yellow representing earlier activation “colliding” with late (purple) activation along the slow pathway region (using CS 5–6 as reference). The map shows the portion of activation illustrated (rainbow segment) out of the entire mapped cycle length (maroon circle). There is a slow-pathway potential noted ...

Frost tolerance is the ability of plants to withstand freezing temperatures without unrecoverable damage. Measuring frost involves various steps, each which will vary depending on objectives study. This systematic map takes an overall view literature that uses measuring techniques in gymnosperms, focusing mainly conifers. Many different have been used for testing, and there has little change me...

The goal of this paper is to present a methodology for the computation invariant tori in Hamiltonian systems combining flow map methods, parameterization and symplectic geometry. While methods reduce dimension be computed by one (avoiding Poincaré maps), cost single step derived Newton-like method proportional FFT. Symplectic properties lead some magic cancellations that make work. multiple sho...

the mathematical aspect of cartographic mapping is a process which establishes a unique connection between points of the earth’s sphere and their images on a plane. it was proven in differential geometry that an isometric mapping of a sphere onto a plane with all corresponding distances on both surfaces remaining identical can never be achieved since the two surfaces do not possess the same gau...
