In a communication network, several vulnerability measures are used to determine the resistance of the network to disruption of operation after the failure of certain stations or communication links. If the communication network is modeled as a simple, undirected, connected and unweighted graph G, then average lower independence number of a graph G can be considered as a measure of graph vulner...

The terminal Wiener index TW = TW (G) of a graph G is equal to the sum of distances between all pairs of pendent vertices of G . This distance–based molecular structure descriptor was put forward quite recently [I. Gutman, B. Furtula, M. Petrović, J. Math. Chem. 46 (2009) 522–531]. In this paper we report results on TW of thorn graphs. Also a method for calculation of TW of dendrimers is descri...

Date palm thorn injuries are common in Middle Eastern countries, where there are many date palm plantations. If detected, these injuries can be treated without subsequent complications. In children, however, the diagnosis can very easily be missed. An untreated embedded thorn may cause late complications, including periostitis or osteomyelitis. In this article, the author presents a case of dat...

Our experience of five children with chronic thorn synovitis indicates that removal of free thorn fragments and all the macroscopically abnormal synovium is required in order to achieve a complete cure. Four children required total synovectomy for diffuse proliferative synovitis and one needed partial synovectomy of the area immediately around the embedded thorn. Joint washouts and partial syno...

Eleven percent of an unselected series of 157 patients with pleural effusion showed a thorn-like protrusion of fluid at the lateral end of the minor fissure at some time during their illnesses. None of a series of 146 normal x-ray films of young patients showed this "thorn sign." The thorn sign is a useful radiographic finding of right-sided pleural effusion.

This paper presents a new approach to domainspecific languages creation. Instead of defining both language syntax and semantics for each case, the same general-purposed markup language Thorn is used. The original model of translation associates commands inside a Thorn document with programs written in some script language. When the compiler needs to execute a command, it launches a correspondin...

Pure palladium thorn clusters were synthesized using the electrodeposition method. The clusters were composed of several thorns growing on one basis. Each thorn was composed of hexahedral units with decreasing sizes. The whole thorn was a single crystal along the <220> direction. The cluster was synthesized by square wave electrodeposition. By changing the deposition factors, a mixture of thorn...

BACKGROUND Thorn injuries are common in the desert Southwest; however, the frequency and microbiology of thorn-associated infections have not been systematically described. Most information comes from case reports describing infections from atypical or environmental microorganisms. Our aim was to summarize the spectrum of thorn-associated infections. METHODS We conducted a retrospective revie...
