Journal of American Physicians and Surgeons Volume 12 Number 2 Summer 2007 34 Development of functional magnetic resonance imaging (fMRI) has opened awhole newwindow on the brain. Patients with severely impaired consciousness, who were previously thought to be incapable of cognitive or sensory function, have been found, with the use of fMRI, to have stimulus-activated cortical networks, despite...

The new materials in public art installations give the birth to interactivity and participation, which in turn, introduces new challenges, not only in the creative design process, but also in how to involve the participants in this process and in evaluating the targeted experience such as such as social connectedness and inclusion. Six design cases are presented, as examples for interactive and...

Theoretical studies have shown a paradoxical destabilizing response of predator–prey ecosystems to enrichment, but there is the gap between the intuitive view of nature and this theoretical prediction. We studied a minimal predator–prey system (a two predator–two prey system) in which the paradox of enrichment pattern can vanish; the destabilization with enrichment is reversed, leading to stabi...

Several investigations show that remittances, renewable energy, and innovation promote the socioeconomic advancement of a nation. Nevertheless, impacts remittances energy on ecological quality are yet to be evaluated thoroughly. Therefore, current investigation assesses effects CO2 emissions while taking into account roles technological innovation, globalization, economic growth. Toward this en...

How cells manage to get equal distribution of their structures and molecules at cell division is a crucial issue in biology. In principle, a feedback mechanism could always ensure equality by measuring and correcting the distribution in the progeny. However, an elegant alternative could be a mechanism relying on self-organization, with the interplay between system properties and cell geometry l...
