We investigate the cost allocation strategy associated with the problem of providing some network service from source to a number of users, via the Minimum Cost Steiner Tree Network that spans the source and all the receivers. The cost of such a Steiner t... see more

 A spanning tree that simultaneously approximates a shortest-path tree and a minimum spanning tree is called a shallow-light tree (shortly, SLT). More specifically, an (a,ß)-SLT of a weighted undirected graph G=(V,E,w) with respec... see more

The study of spanning trees and Steiner trees arises naturally in applications, such as in the design of integrated circuit boards, communication networks, power networks and pipelines of minimum cost. In such applications the Steiner ratio is an indicati... see more

The rectilinear Steiner ratio was shown to be 3/2 by Hwang [Hwang FK, 1976, On Steiner minimal trees with rectilinear distance, SIAM Journal on Applied Mathematics, 30, pp. 104–114.]. We use continuity and introduce restricted point sets to obtain an alte... see more

The brown tail moth, Euproctis chrysorrhoea, is an important foliar pest of forest trees in most areas of Europe and Asia. Therefore, the potential of the entomopathogenic nematodes Heterorhabditis bacteriophora isolate IRAZ5 and Steinernema carpocapsae i... see more

Body measurements taken throughout nematode development of Tylenchorhynchus claytoni showed that stylet length, position of excretory pore and de Man rations a, b, and c were highly correlated to body length (size-grouping) while the position of vulva, as... see more

A survey of plant-parasitic nematodes of vegetable and fruit crops was undertaken in the Ghor area in Jordan. From the 74 samples of soil and roots, 67 plant-parasitic nematode species, belonging to 32 genera, were recovered and identified. Meloidogyne ja... see more

The peachtree borer, Synanthedon exitiosa (Say 1823), is a major pest of stone fruit trees in North America. Current management relies upon preventative control using broad-spectrum chemical insecticides, primarily chlorpyrifos, applied in the late summer... see more

Ornamental flowers, shrubs and trees are economically important commodities in the US and around the globe. In this study we evaluated the potential of entomopathogenic nematodes to control two important ornamental pests: 1) Corythucha ciliata (Say) (Hemi... see more
