The current study set out to evaluate how individuals walk through apertures created by different stationary obstacles. Specifically, we examined whether the passability of apertures differed between human and pole obstacles by quantifying aperture crossing behaviors such as the critical point. Participants walked an 8m path toward a visible goal located at the end. Two obstacles were positione...

The in-plane optical anisotropy (IPOA) in InAs/GaSb superlattices has been studied by reflectance difference spectroscopy (RDS) at different temperatures ranging from 80 to 300 K. We introduce alternate GaAs- and InSb-like interfaces (IFs), which cause the symmetry reduced from D 2d to C 2v . IPOA has been observed in the (001) plane along [110] and [1[Formula: see text]0] axes. RDS measurement...

INTRODUCTION Ethiopia has a growing private health sector. In recent years, the directly observed treatment short course (DOTS) strategy was initiated in selected private health facilities in the country. The objective of the present study was to assess knowledge and practice of private practitioners in tuberculosis (TB) control in Amhara Region, Ethiopia. METHODOLOGY An institution-based cro...

OBJECTIVES Determine effects of a limited-enforcement intelligent tutoring system in dermatopathology on student errors, goals and solution paths. Determine if limited enforcement in a medical tutoring system inhibits students from learning the optimal and most efficient solution path. Describe the type of deviations from the optimal solution path that occur during tutoring, and how these devia...

In many situations we are faced with the need to estimate the number of classes in a population from observed count data: this arises not only in biology, where we are interested in the number of taxa such as species, but also in many other fields such as public health, criminal justice, software engineering, etc. This problem has a rich history in theoretical statistics, dating back at least t...

CASE SHOWING THE CONTAGIOUSNESS OF PHTHISIS. A man of thirty-four had been sick with phthisis about four years; gradually grew from bad to worse, until the usual end was reached. It was not until the last three or four months of his life that he was confined to his bed. He was fond of pets, and during these three or four mouths, it was hia fancy to have his dog in the room nearly all the time. ...

It is important to transmit pictures efficiently in most Web sites, especially for those users with low bandwidth connections. In this demonstration, we propose a system which progressively transmits images using a very low transmission rate (as low as 15% in some cases). The transmitted images maintain a reasonable picture quality for the users to browse images quickly. Interested readers can ...

Behavioral studies have shown that picture-plane inversion impacts face and object recognition differently, thereby suggesting face-specific processing mechanisms in the human brain. Here we used event-related potentials to investigate the time course of this behavioral inversion effect in both faces and novel objects. ERPs were recorded for 14 subjects presented with upright and inverted visua...
