We introduce the new concept of the chromatic sum of a graph G, the smallest possible total among all proper colorings of G using natural numbers. We show that computing the chromatic sum for… (More)

Let S be a set of n objects. A binary tree of S is a binary tree whose leaves are labeled without repetition from S. The operation of pruning a tree T is that of removing some leaves from T and… (More)

Given two binary trees, a largest subtree contained in both of the original trees that has been obtained by pruning vertices is called an agreement subtree. An exact algorithm for finding an… (More)

The localisation of poly(A) RNA in plant cells containing either reticular (Allium cepa) or chromocentric (Lupinus luteus, Arabidopsis thaliana) nuclei was studied through in situ hybridisation. In… (More)

Abstract Let G be a graph and u, v two vertices of G . Then the interval from u to v consists of all those vertices that lie on some shortest u — v path. Let S be a set of vertices in a connected… (More)

In this paper the concept of the distance between graphs is applied to the problem of recognizing objects. An unknown object is represented by a graph H and from the data base of possible solutions… (More)

IntroductionWe hypothesize that the combination of transarterial embolization (TAE) plus inhibition of lactate export will limit anaerobic metabolism and reduce tumor survival compared to TAE alone.… (More)

In th i s paper we give the parametric representation of a s t a r l i k e map of the unit b a l l Bn into C n . Bes ides , we prove the existence and the uniqueness of the solut ion of the equation… (More)
