Triples of Orthogonal Latin and Youden Rectangles For Small Orders
Journal of Combinatorial Designs, Volume 27, Issue 4, p. 229-250, doi.org/10.1002/jcd.21642 Abstract We have performed a complete enumeration of nonisotopic triples of mutually orthogonal Latin rectangle. Here we will present a census of such triples, classified by various properties, including the order of the autotopism group of the triple. As part of this, we have also achieved the first enumeration of pairwise orthogonal triples of Youden rectangles. We have also studied orthogonal triples of rectangles which are formed by extending mutually orthogonal triples with nontrivial autotopisms one row at a time, and requiring that the autotopism group is nontrivial in each step. This class includes a triple coming from the projective plane of order 8. Here we find a remarkably symmetrical pair of triples of rectangles, formed by juxtaposing two selected copies of complete sets of mutually orthogonal Latin squares of order 4.
Modeling bacterial attenuation in onsite waste-water treatment systems using the active region model and column-scale data
Environmental Earth Sciences 74(6), pp. 4827-4837, doi: 10.1007/s12665-01 Abstract Bacterial attenuation in porous media is often higher in columns than in the field. This study investigates whether this

Three days of separation
The idea that we are only six introductions away from any other person on this planet is both beautiful and compelling. It has inspired research, provided inspiration to a film starring Will Smith and.
