A stab wound penetrating the left atrium (excluding the left auricle) would have to penetrate through other chambers of the heart or through the great arteries at their origin from the heart to reach the left atrium from the front of the chest. Such wounds would be fatal, the patient dying from profuse haemorrhage within a few minutes. A stab wound through the back of the chest could reach the ...

[Purpose] The objective of the study was to compare the incidence, diagnosis, treatment, and prognosis of patients with spinal cord stab injury to those with the more common spinal cord contusion injury. [Subjects] Of patients hospitalized in China Rehabilitation Research Center from 1994 to 2014, 40 of those having a spinal cord stab injury and 50 with spinal cord contusion were selected. [Met...

The extension complexity xc(P ) of a polytope P is the minimum number of facets of a polytope that affinely projects to P . Let G be a bipartite graph with n vertices, m edges, and no isolated vertices. Let STAB(G) be the convex hull of the stable sets of G. Since G is perfect, it is easy to see that n 6 xc(STAB(G)) 6 n+m. We improve both of these bounds. For the upper bound, we show that xc(ST...

conclusions although evaluations of the initial vital signs and physical examinations are still important, the history regarding the source of the stab wounds (aisw vs. sisw) may be helpful in determining the appropriate treatment methods and predicting patient outcomes. results a total of 19 patients had undergone exploratory laparotomy. of the nine patients with sisw undergoing this procedure...

A patient with stab wounds to the chest may have negative physical findings, and normal radiologic examinations and still develop delayed pneumothorax or hemothorax. The frequency and time intervals of these complications have not been established. One hundred ten asymptomatic patients with chest stab wounds were prospectively studied. All patients had normal chest radiographs on initial evalua...

A graph G is called (H; k)-vertex stable if G contains a subgraph isomorphic to H ever after removing any k of its vertices; stab(H; k) denotes the minimum size among the sizes of all (H; k)-vertex stable graphs. In this paper we deal with (Cn; k)vertex stable graphs with minimum size. For each n we prove that stab(Cn; 1) is one of only two possible values and we give the exact value for infini...

An extensive review of the literature showed that trauma is the most common cause of pneumocephalus. Most often the trauma involves the frontoethmoidal or other air sinuses. Three types of injuries are frequently described to be responsible for pneumocephalus: (1) automobile accidents, (2) motorcycle accidents, and (3) missile injuries. A thorough review of the literature revealed that there is...

Non-missile penetrating brain injuries are rare events in western countries. We report a case with lethal stab injury of the brain and identification of the weapon used in the assault by digital superimposition on CT scans taken at admission of the victim to a hospital. Furthermore, all cases with knife stab wounds of the skull between 1971 and 2000 were analyzed and compared with literature re...

Perfect graphs constitute a well-studied graph class with a rich structure, reflected by many characterizations w.r.t different concepts. Perfect graphs are, e.g., characterized as precisely those graphs G where the stable set polytope STAB(G) coincides with the clique constraint stable set polytope QSTAB(G). For all imperfect graphs STAB(G) ⊂ QSTAB(G) holds and, therefore, it is natural to mea...
