We study the problem of finding lowest common ancestors (LCA) in trees and directed acyclic graphs (DAGs). Specifically, we extend the LCA problem to DAGs and study the LCA variants that arise in this general setting. We begin with a clear exposition of Berkman and Vishkin’s simple optimal algorithm for LCA in trees. Their ideas lay the foundation for our work on LCA problems in DAGs. We presen...

OBJECTIVE This study investigated the utility of the Koppitz administration, scoring and norms for the Bender Gestalt Test (BGT) as a neurocognitive screening instrument for Sesotho-speaking children. METHOD The BGT protocols of 671 Sesotho-speaking children between the ages of seven and nine were reviewed. Data pertaining to socioeconomic status were also gathered for 360 of the participants...

The picture (Figure 1) showing a markedly virilized central figure with an infant at the breast was painted in 1631 by Jose Ribera, a Spaniard living in Naples. It was commissioned by Ribera's patron, the Duke of Alcala and in due course returned to Spain. It was exhibited in Paris and in the Royal Academy of San Fernando in the early 19th century and hung for many years in the Hospital Tavera ...

Today's personalized news systems relieve the reader of much of the burden of filtering through the immense amounts of information available at any given minute. However, few take into account changes in a reader's day-to-day life and how these changes may affect his or her interests. This thesis describes a personalized news system that uses observations of the reader's environment to augment ...

Classical sorting by reversals uses the unit-cost model, that is, each reversal consumes an equal cost. This model limits the biological meaning of sorting by reversal. Bender and his colleagues extended it by assigning a cost function f(l) = l(alpha) for all alpha > or =0, where l is the length of the reversed subsequence. In this paper, we extend their results by considering a model in which ...

In a recent paper Ahlgren, Ono and Penniston described the L-series of K3 surfaces from a certain one-parameter family in terms of those of a particular family of elliptic curves. The Tate conjecture predicts the existence of a correspondence between these K3 surfaces and certain Kummer surfaces related to these elliptic curves. A geometric construction of this correspondence is given here, usi...
