Apollonius Solutions in Rd
Voronoi and related diagrams have technological applications, for example, in motion planning and surface reconstruction, and also find significant use in materials science, molecular biology, and crystallography. Apollonius diagrams arguably provide the most natural division of space for many materials and technology problems, but compared to Voronoi and power diagrams, their use has been limi...
متن کاملRD-flatness and RD-injectivity
It is proved that every commutative ring whose RD-injective modules are Σ-RD-injective is the product of a pure semi-simple ring and a finite ring. A complete characterization of commutative rings for which each artinian (respectively simple) module is RD-injective, is given. These results can be obtained by using the properties of RD-flat modules and RD-coflat modules which are respectively th...
متن کاملSolutions to the 63 rd
A3 Note that each of the sets {1}, {2}, . . . , {n} has the desired property. Moreover, for each set S with integer average m that does not contain m, S ∪ {m} also has average m, while for each set T of more than one element with integer average m that contains m, T \{m} also has average m. Thus the subsets other than {1}, {2}, . . . , {n} can be grouped in pairs, so Tn −n is even. A4 (partly d...
متن کاملEarly markers of retinal degeneration in rd/rd mice.
PURPOSE In the rd/rd mouse, the cell death of rod photoreceptors has been correlated to abnormal levels of the cyclic nucleotide cGMP within photoreceptors. Given that cGMP is required for opening of the cationic channels, there is the possibility that a high cGMP concentration would maintain these channels open, at a high energy cost for the retina. METHODS We investigated whether cation cha...
