Unitarity triangle test of the extra factor of two in particle oscillation phases

S. M. Bilenky, W. Grimus, T. Schwetz
2005 European Physical Journal C: Particles and Fields  
We demonstrate that the unitarity triangle (UT) fit in the Standard Model with three families is a suitable means to discriminate between the standard oscillation phase and the phase with an extra factor  ...  There are claims in the literature that in neutrino oscillations and oscillations of neutral kaons and B-mesons the oscillation phase differs from the standard one by a factor of two.  ...  It is likely that in the future, with accumulated data used in the unitarity triangle fit, the exclusion of the extra factor of two will become even more significant.  ...

Maximal sets of triangle-factors onv = 6m vertices

Rolf S. Rees
1998 Journal of combinatorial designs (Print)  
A collection of edge-disjoint triangle-factors on K 3n is called maximal if it cannot be extended by a further triangle-factor.  ...  It is well-known that a maximal set must therefore contain at least % triangle factors.  ...  triangle-factors with the two triangle-factors in the RRP (12, 9) ; this gives two triangle-factors on AU B.  ...

Heronian Triangles

This paper presents some theorems regarding factors of the sides and area of Heronian triangles. 2. Rational triangles. In the July, 1921, issue of this Monthly, Professor L. E.  ...  Any factor common to two v's is prime to all the d’s and n’s. Now since every d and 1 is 1 or greater, the minimum value of d?+n? is 2. (In this case only, our Heronian triangle is a right triangle.)  ...

Triangle-factors in a balanced blown-up triangle

Robert Johansson
2000 Discrete Mathematics  
Let G be a 3-partite graph with 3n vertices, n in each class, such that each vertex is connected to at least 2 3 n + √ n of the vertices in each of the other two classes.  ...  In this paper it will be proved that G contains n vertex-disjoint triangles, it will also be shown by example that this is close to being sharp.  ...  Therefore some triangle T = T i in F must satisfy |E(P; T )|¿4l + 2.  ...

Simple models of the impact of overlap in bucket rendering

Milton Chen, Gordon Stoll, Homan Igehy, Kekoa Proudfoot, Pat Hanrahan
1998 Proceedings of the ACM SIGGRAPH/EUROGRAPHICS workshop on Graphics hardware - HWWS '98  
If triangles are small, the overlap factor itself is also small. If triangles are large, overlap is high but pixel work dominates the rendering time.  ...  The drawbacks of this technique are the cost of computing the regions overlapped by each triangle and the redundant work required in processing triangles multiple times when they overlap multiple regions  ...  Head Cylhead Studio Flight Quake APPENDIX Worst-Case Overlap Factor The expected number of tiles overlapped by two triangles of total bounding-box area 2B is: 2 2 2         + +        ...

Ascending subgraph decompositions of oriented graphs that factor into triangles

Andrea D. Austin, Brian C. Wagner
2020 Discussiones Mathematicae Graph Theory  
In this paper, we will show that all orientations of an oriented graph that can be factored into triangles with a large portion of the triangles being transitive have an ASD.  ...  We will also use the result to obtain an ASD for any orientation of complete multipartite graphs with 3n partite classes each containing 2 vertices (a K(2 : 3n)) or 4 vertices (a K(4 : 3n)).  ...  Acknowledgments The research for this paper was funded in part by the Bill and Roberta Blankenship Undergraduate Research Endowment.  ...

In phase 2, the 2-P algorithm backtracks the reduction steps and computes MRI, based on the reduction factors generated in phase 1 and a set of closed-form TR formulas.  ...  In each reduction step, the 2-P algorithm generates the correlation, quantified by a reduction factor, between the original network and the reduced network.  ...  The new success probabilities are recomputed, as shown in Fig. 2 . , because of a transformation factor of 1 in this step.  ...
