This philosophical conflict has resulted in stalemates on many health care issues, and the administration’s proposed 2009 budget, which calls for reductions of $200.9 billion in Medicare and Medicaid spending over the next 5 years, only deepens the pol...

Research at continental rifts, mid-ocean ridges, and transforms has shown that new plates are created by extensional tectonics, magma intrusion, and volcanism. Studies of a wide variety of extensional processes ranging from plate thinning to magma intrusion have helped scientists understand how continents are broken apart to form ocean basins. However, deformation processes vary significantly d...

Results of cognitive psychology research are analysed to explain why it is diicult for retrieval system users to bring to mind alternative search terms. A human memory model is modiied in such a way that it produces additional search terms instead of human associations. A small experiment shows that such a spreading activation network can nd alternative terms-with a performance similar to the n...

Research on the cognitive consequences of bilingualism suggests a bilingual advantage: early experience with more than one language predicts better inhibitory control of attention. The mechanisms responsible for this advantage, however, are not well understood. We ask whether depth and time-course of memory encoding may be responsible. We measured bilingual and monolingual adults’ memory for no...

Precise measurement of temperature distribution and thermal behavior in microscopic regions is critical many research fields. We demonstrate lock-in thermography using nitrogen-vacancy centers diamond nanoparticles. successfully visualize diffusion glass coverslip Teflon with micrometer resolution deduce their diffusivity. By spreading nanoparticles over the sample surface, variation can be mea...

Fault development at mid-ocean ridge spreading centers is strongly dependent on the thermal state of the axial lithosphere. Thermal conditions at a ridge axis are a combined function of spreading rate, mantle temperature, magma injection, and hydrothermal circulation. In this study, we test the sensitivity of fault development in slow-spreading environments to the efficiency of hydrothermal coo...

Plate divergence along mid-ocean ridges is accommodated through faulting and magmatic accretion, and, at overlapping spreading centers (OSC), distributed across two curvilinear ridge axes. One-meter resolution bathymetry acquired by autonomous underwater vehicles, combined with distribution ages of lava flows, used to: (a) analyze the spatial temporal faults, fissures in OSC between distal sout...

Cloud Computing is one of the fast spreading technologies for providing utility-based IT services to its user. Large-scale virtualized data-centers are established to meet this requirement. Data centers consumes large amount of computation power for providing efficient and reliable services to its user. Such large consumption of electrical energy has increased operating cost for the service pro...
