Abstract Since the finance industry is transforming into a data industry, measuring quantity of investors have about various assets important. Informed by structural model, we develop such cross-sectional measure. We show how our measure differs from price informativeness and use it to document new fact: large high-growth firms becoming increasingly abundant, relative other firms. Our model off...

At its introduction in the management of pediatric asthma, montelukast was regarded as a potentially revolutionary drug due to mechanism action and easy clinical applicability. Nevertheless, use daily practice evidence from trials have shown that, rather than radical change approach asthmatic children, more likely represents second-line medication that is useful when inhaled steroids alone fail...

The authors report the case of a 61-year-old patient who underwent internal fixation with a dynamic hip screw for a stable intertrochanteric fracture of the right hip. The immediate postoperative radiograph showed complete intrapelvic migration of the threaded guide pin, which has gone unnoticed during operation. The pin was removed by laparotomy, and was found to have damaged no pelvic viscera...

The behavior of classical mechanical systems is characterized by their phase portraits, the collections of their trajectories. Heisenberg's uncertainty principle precludes the existence of sharply defined trajectories, which is why traditionally only the time evolution of wave functions is studied in quantum dynamics. These studies are quite insensitive to the underlying structure of quantum ph...
