Abstract: An example embodiment may involve estimating, from genetic data of a plurality of individuals, identity-by-descent (IBD) segments; forming, from the IBD segments, a relationship graph representing genetic linkages between the individuals; determining, by applying a stochastic block model to the relationship graph, a plurality of genetic groups, wherein each of the genetic groups is assigned a respective subset of the individuals who share a greater amount of IBD segment length with one another than with a further respective subset of the individuals who are in other of the genetic groups; and training, for each of the genetic groups, a respective classifier based on (i) input including genome-wide local ancestry proportions of the individuals and sums of IBD segments for the individuals in the respective genetic group, and (ii) associated output of assignments of the individuals to the genetic groups.

Abstract: A system of architectural moldings that form a passage for electrical wiring (30), coaxial cables, fiber optic cables, and associated devices used in transmitting low-voltage power, communication, and control signals. The architectural moldings may also be used to cover pre-existing wiring raceways and conduits. The system may be installed when constructing a building or when retrofitting an existing structure. The moldings can be removably mounted on the interior surfaces of residential and commercial structures in a manner that allows for easy removal and replacement of some or all of the moldings without disturbing the enclosed wiring and cables or harming finished surfaces. The moldings may be made of wood, polyurethane, fiberboard, or any material suitable for manufacturing pieces that resemble baseboards, cornice moldings, chair rails, casings, or other interior millwork.
