We view sensemaking in threat analysis as abducing stories that explain the current data and make verifiable predictions about future data. We have developed a preliminary system, called STAB, that abduces multiple stories from the VAST2006 dataset. STAB uses the TMKL knowledge representation language to represent skeletal story plots as plans with goals and states, and to organize the plans in...

Cases at study comprise 21 sharp force fatalities (9 suicides--7 m and 2 f; 8 homicides--5 m and 3 f; 2 accidental deaths--1 m and 1 f; 2 uncertain cases--2 m), examined from 1993 to 2002. Suicide age range was 17-75 years, mean 42.4; in seven cases the age was upper 40. Scene of death was at home in six cases, at open place in two, during hospitalisation in one. Incised wounds were pre-eminent...

A recent result of Balandraud shows that for every subset S of an abelian group G there exists a non trivial subgroup H such that |TS| ≤ |T |+ |S| − 2 holds only if H ⊂ Stab(TS). Notice that Kneser’s Theorem only gives {0} 6= Stab(TS). This strong form of Kneser’s theorem follows from some nice properties of a certain poset investigated by Balandraud. We consider an analogous poset for nonabeli...

Background Abdominal stab injury is potential life-threatening injuries. Operation should be considered if wound violate the peritoneal layer and/or complicated with hemodynamic compromise, peritonitis, impalement, or evisceration. It is well known there are several diagnostic tools to evaluate the necessity of operation for a patient with abdominal stab injury. Despite numerous diagnostic tool...

The sensemaking task in investigative analysis generates models that connect entities and events in an input stream of data. We describe a knowledge system for aiding sensemaking in investigative analysis. The STAB system represents crime schemas as hierarchical scripts with goals and states. It generates multiple explanatory hypotheses for an input data stream containing interleaved sequences ...

We would like to present a case report of a very unusual suicide attempt. A 48-year-old female patient tried to commit suicide by stabbing herself with a kitchen knife into her neck. Suicide by self-stabbing is uncommon, constituting only 1-3% of suicide attempts. Patients with self-inflicted stab wounds may have a higher incidence of surgical interventions based on the stab location. Surprisin...

In this paper nondegenerate multidimensional matrices of boundary format in V0 ⊗ · · · ⊗ Vp are investigated by their link with Steiner vector bundles on product of projective spaces. For any nondegenerate matrix A the stabilizer for the SL(V0)×· · ·×SL(Vp)action, Stab(A), is completely described. In particular we prove that there exists an explicit action of SL(2) on V0 ⊗ · · · ⊗ Vp such that ...
