The space of Bridgeland stability conditions on the bounded derived category of coherent sheaves on P2 has a principle connected component Stab(P2). We show that Stab†(P2) is the union of geometric and algebraic stability conditions. As a consequence, we give a cell decomposition for Stab (P2) and show that Stab†(P2) is contractible. Introduction Motivated by the concept of Π-stability conditio...

BACKGROUND The purpose of this study was to examine the mortality rate of penetrating cardiac trauma in a large urban hospital. METHODS This was a retrospective study over a period of 5 years and 5 months of all patients admitted alive with a stab or a gunshot cardiac injury. RESULTS There were 310 patients with a stab wound and 63 with a gunshot wound. The overall mortality rate was 19%. T...

OBJECTIVE To evaluate the discriminatory power of TraumaSCAN-Web, a system for assessing penetrating trauma, using retrospective multi-center case data for gunshot and stab wounds to the thorax and abdomen. METHODS 80 gunshot and 114 stab cases were evaluated using TraumaSCAN-Web. Areas under the Receiver Operator Characteristic Curves (AUC) were calculated for each condition modeled in Traum...

Let $\mathrm{h}\mathscr{C}$ be the homotopy category of a stable infinity $\mathscr{C}$. Then $\mathrm{h}\mathscr{C}^{\Delta^{1}}$ morphisms in $\mathscr{C}$ is also triangulated. Hence space $\mathsf{Stab}\,{ \mathrm{h}\mathscr{C}^{\Delta^{1}}}$ stability conditions on well-defined though non-emptiness not obvious. Our basic motivation comparison type $\mathsf{Stab}{\mathrm{h}\mathscr{C}}$ and...

The purpose of this research was to enhance the stab resistance of protective clothing material by developing a new high-density nonwoven structure. Ice picks often injure Japanese police officers due to the strict regulation of swords in the country. Consequently, this study was designed to improve stab resistance against ice picks. Most existing anti-stab protective clothing research has focu...

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...

INTRODUCTION A dynamometer employing a stabilization procedure (lumbar extension machine, MedX, Ocala, FL) is effective in improving strength and reducing symptoms of low back pain (LBP), and researchers have hypothesized that this effectiveness is due to the pelvic stabilization. However, effects of the dynamometer with and without pelvic stabilization on LBP have not been compared: This was t...

This article discusses the assessment, management and treatment of patients with stab wounds on arrival in the emergency department. It describes the immediate approach to assessment. The assessment of stab wounds to the chest, abdomen and limbs is also examined.

Background: Stab wounds are common in homicide cases. Post-mortem multislice computed tomography (PMCT) has proved to be a useful tool in forensic examinations of victims of sharp force trauma, but due the limited resolution of soft tissues, the radiological depiction of a stab channel is difficult. In this study, we have tried to obtain information about the shape of a knife blade by CT scanni...

Traumatic injury to the brain initiates an increase in astrocyte and microglial infiltration as part of an inflammatory response to injury. Increased astrogliosis around the injury impedes regeneration of axons through the injury, while activated microglia release inflammatory mediators. The persistent inflammatory response can lead to local progressive cell death. Modulating the astrocyte and ...
