Detecting a Theta or a Prism
نویسندگان
چکیده
A theta in a graph is an induced subgraph consisting of two nonadjacent vertices joined by three disjoint paths. A prism in a graph is an induced subgraph consisting of two disjoint triangles joined by three disjoint paths. This paper gives a polynomial-time algorithm to test whether a graph has an induced subgraph that is either a prism or a theta.

Transmission of p- and s-polarized light through a prism and the condition of minimum deviation.
The condition of minimum deviation (MD) by a transparent optically isotropic prism is re-derived, and expressions for the intensity transmittances T(p)(theta) and T(s)(theta) of an uncoated prism of refractive index n and prism angle alpha for incident p- and s-polarized light and their derivatives with respect to the internal angle of refraction theta are obtained. When the MD condition (theta...
متن کاملMethod of calculating the alignment tolerance of a Porro prism resonator.
A method of calculating the angular alignment tolerance of a Porro prism laser oscillator is presented. The reduction in mode volume due to misalignment is found by a ray optical approach. An analytical expression for alignment tolerance, in terms of resonator length L, prism azimuth angle theta, rod location L(2), and rod aperture radius alpha is obtained. An experiment was set up to measure t...

متن کاملPRISM: Pair-read informed split-read mapping for base-pair level detection of insertion, deletion and structural variants
MOTIVATION The development of high-throughput sequencing technologies has enabled novel methods for detecting structural variants (SVs). Current methods are typically based on depth of coverage or pair-end mapping clusters. However, most of these only report an approximate location for each SV, rather than exact breakpoints. RESULTS We have developed pair-read informed split mapping (PRISM), ...
