The massless conformally coupled scalar field is characterized by the so-called “new improved stress-energy tensor”, which is capable of classically violating the null energy condition. When coupled to Einstein gravity we find a three-parameter class of exact solutions. These exact solutions include the Schwarzschild geometry, assorted naked singularities, and a large class of traversable wormh...

Beta-amyloid (Abeta), the primary protein component of Alzheimer's plaques, is neurotoxic when aggregated into fibrils. We have devised a modular strategy for generating compounds that inhibit Abeta toxicity. These compounds contain a recognition element, designed to bind to Abeta, linked to a disrupting element, designed to interfere with Abeta aggregation. On the basis of this strategy, a hyb...

The Moon is the closest astronomical object to the Earth, and the only one on which we can see significant surface features with our naked eyes (the Sun is too bright, and everything else is pointlike or, like the Andromeda galaxy, too dim). As a result, it has from time immemorial inspired many fanciful notions, including that the Moon is inhabited. In fact, life on the Moon was the subject of...

In this paper, we share our experience of applying the modern multimedia technologies to the traditional performing art in a drumming performance project, U-Drumwave. By deploying an interactive system on the drumming stage, the audience will see augmented visual objects moving on the stage in accord with the performer’s drumming rhythms. The creation and display of the visual objects are integ...

the issue of the property of computer data is veryimportant in different sciences such as religiousjurisprudence, law, economy and even computer science.the proof for the property of such data can have someeffects as well as civil and criminal acts. the nature ofthese data and their property require essential explanation.in this study, computer data is defined and then, it iscompared with diffe...

Endocrine-disrupting compounds are exogenous agents that interfere with the natural hormones of the body. Human biological monitoring is a powerful method for monitoring exposure to endocrine disrupting compounds. In this review, we describe human biological monitoring systems for different groups of endocrine disrupting compounds, polychlorinated biphenyls, brominated flame retardants, phthala...
