Intracerebral hemorrhage (ICH) constitutes 10% to 30% of first-ever strokes and is associated with high morbidity and mortality. The reported 30-day mortality of ICH ranges from 30% to 50% and nearly half of the patients died within 2 days after the onset of symptoms. The initial hematoma volume, level of consciousness, and intraventricular extension of bleeding are well-established predictors ...

Abstract Target signatures are discrete quantities computed from measured scattering data that could potentially be used to classify scatterers or give information about possible defects in the scatterer compared an ideal object. Here, we study a class of modified interior transmission eigenvalues intended provide target for inverse fluid–solid interaction problem. The modification is based on ...

The current study examines how holding misconceptions about key problem features affects students’ ability to solve algebraic equations correctly and to learn correct procedures for problem solution. Algebra I students learning to solve simple equations using the Cognitive Tutor curriculum (Koedinger, Anderson, Hadley, & Mark, 1997) completed a pretest and posttest designed to evaluate their co...

We extend the study of the complexity of computing an εapproximate Nash equilibrium in symmetric congestion games from the case of positive delay functions to delays of arbitrary sign. Our results show that with this extension the complexity has a richer structure, and it depends on the exact nature of the signs allowed. We first prove that in symmetric games with increasing delay functions and...

The presently accelerating universe may keep accelerating forever, eventually run into the event horizon problem, and thus be in conflict with the superstring idea. In the other way around, the current accelerating phase as well as the fate of the universe may be swayed by a negative cosmological constant, which dictates a big crunch. Based on the current observational data, in this paper we in...

The study investigates the causal link between trade openness and economic growth for four South Asian countries for period 1972-1985 and 1986-2007 to examine the scenario before and after the implementation of SAARC. Panel cointegration and FMOLS techniques are employed for short run and long run estimates. In 1972-85 short run unidirectional causality from GDP to openness is found whereas, in...

a projective parameter of a geodesic as solution of certain ode is defined to be a parameter which is invariant under projective change of metric. using projective parameter and poincaré metric, an intrinsic projectively invariant pseudo-distance can be constructed. in the present work, solutions of the above ode are characterized with respect to the sign of parallel ricci tensor on a finsler s...

OBJECTIVE To evaluate preoperative real-time dynamic transvaginal sonography (TVS) in the prediction of pouch of Douglas (POD) obliteration in women undergoing laparoscopy for suspected endometriosis. METHODS This was a multicenter prospective observational study undertaken from January 2009 to November 2011. All women with symptoms suggestive of endometriosis who were scheduled for laparosco...

BACKGROUND Despite the existence of detailed consensus guidelines, challenges remain regarding efficient, appropriate, and safe imaging methods for the diagnosis of suspected pulmonary embolism. AIMS To investigate the role of the wedge sign, B-lines, and pleural effusion seen on bedside lung ultrasound in the diagnosis of pulmonary embolism. STUDY DESIGN Diagnostic accuracy study. METHOD...

BACKGROUND A positive Hutchinson's sign indicates an increased risk of ocular involvement in herpes zoster ophthalmicus (HZO). We examined the sensitivity of Hutchinson's sign as an indicator of ocular involvement in a consecutive series of patients presenting with HZO. METHODS We conducted a descriptive observational prospective study of patients > or =18 years old presenting with HZO and co...
