Quantum fluctuations of Cosmological Perturbations in Generalized Gravity [PDF]
, 1996 Recently, we presented a unified way of analysing classical cosmological perturbation in generalized gravity theories. In this paper, we derive the perturbation spectrums generated from quantum fluctuations again in unified forms. We consider a situation

Elastic-Tether Suits for Artificial Gravity and Exercise [PDF]
Body suits harnessed to systems of elastic tethers have been proposed as means of approximating the effects of normal Earth gravitation on crewmembers of spacecraft in flight to help preserve the crewmembers physical fitness. The suits could also be used

Vacuum driven accelerated expansion [PDF]
, 2008 It has been shown that an improved estimation of quantum vacuum energy can yield not only acceptable but also experimentally sensible results. The very idea consists in a straightforward extraction of gravitationally interacting part of the full quantum ...

The WTO Promotes Trade, Strongly But Unevenly [PDF]
Contrary to the recent literature that concludes that the GATT/WTO has been completely ineffective in promoting world trade, this paper furnishes robust evidence that the institution has had a powerful and positive impact on trade.
