Kenyan dominance in distance running

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2003
Critical physiological factors for performance in running are maximal oxygen consumption (VO(2max)), fractional VO(2max) utilization and running economy. While Kenyan and Caucasian elite runners are able to reach very high, but similar maximal oxygen uptake levels, the VO(2max) of black South African elite runners seems to be slightly lower.

Distance Domination in Graphs

2020
For an integer k ≥ 1, a (distance) k-dominating set of a connected graph G is a set S of vertices of G such that every vertex of V (G) ∖ S is at distance at most k from some vertex of S. The k-domination number, γk(G), of G is the minimum cardinality of a k-dominating set of G. In this chapter, we survey selected results on the k-domination number of a

Short-distance dominance of vertex functions

Physical Review D, 1975
In order to calculate high-energy high-momentum-transfer processes for particles described by composite fields one needs to know some uniformity properties of the external-particle vertex function. We examine such a vertex function in a scalar theory in six dimensions in the case in which anomalous dimensions are realized. We start from the result that,

On distance-s locating and distance-t dominating sets in graphs

Discrete Mathematics, Algorithms and Applications, 2023
Let [Formula: see text] and [Formula: see text] be positive integers, and let [Formula: see text] be a simple and connected graph with vertex set [Formula: see text]. For [Formula: see text], let [Formula: see text] denote the length of an [Formula: see text] geodesic in [Formula: see text] and let [Formula: see text]. Let [Formula: see text].

Distance-Hereditary Graphs, Steiner Trees, and Connected Domination

SIAM Journal on Computing, 1988
Summary: Distance-hereditary graphs have been introduced by Howorka and studied in the literature with respect to their metric properties. In this paper several equivalent characterizations of these graphs are given: in terms of existence of particular kinds of vertices (isolated, leaves, twins) and in terms of properties of connections, separators ...
