The Southwestern United States desert serves as the host for several threatened and endangered species, one of which is the desert tortoise (Gopherus agassizii). The goal of this study was to develop a fine-scale, remote-sensing-based approach that indicates favorable burrow locations for G. agassizii in the Boulder City (Nevada) Conservation Easement area (35,500 ha). This was done by analyzin...

Three hypotheses have attempted to explain the phenomenon of contagious yawning. It has been hypothesized that it is a fixed action pattern for which the releasing stimulus is the observation of another yawn, that it is the result of non-conscious mimicry emerging through close links between perception and action or that it is the result of empathy, involving the ability to engage in mental sta...

Previous data have shown that the Former Yugoslavia had a significant role in exports of land tortoises (Testudo spp.) during the past century. In this paper we present historical exploitation and compare dynamics of the trade in land tortoises in the former Yugoslavia according to Federal Statistical Office and Convention on International Trade in Endangered Species of Wild Fauna and Flora (CI...

The desert tortoise (Gopherus agassizii) is federally listed as "threatened" and is afforded protection in several U.S. states including California, Nevada, Utah, and Arizona. Numerous factors ranging from habitat destruction to disease are thought to contribute to the species' decline throughout its range. Data collection on desert tortoises in the wild is challenging because tortoises are sec...

We construct a new type of Chandrasekhar transformation in Kerr spacetime using the different tortoise coordinate, which is useful for exact analysis to study Teukolsky equation with arbitrary frequency. also give interpretation our formalism quantum Seiberg-Witten geometry.

We investigated the effects of changing the teleoperation feel of operating a robot by modifying its speed and acceleration profiles, and found that reducing a robot’s maximum speed by half can reduce collisions by 32%, while only increasing navigation task time by 10%. Teleoperated robots are increasingly popular for enabling people to remotely attend meetings, explore dangerous areas, or view...

he men of old were born like the wild beasts. In woods, caves, and groves, they lived on food gathered in the fi elds, " wrote Marcus Vitruvius Pollio more than 2,000 years ago in his well-known account of classical traditions in architecture. One day, a dense group of trees, agitated by winds and storms, caught fi re. Humans nearby ran from the fl ames but then, attracted to the warmth, began ...
