Motivated by the recent work of Saridakis [1], we generalize this work to the noninteracting case. Using an additional canonical scalar field, we formulate HořavaLifshitz cosmology with an effective interacting dark energy sector. ∗E-mail: [email protected]

Understanding the intrinsic data locality of a workload is essential to understanding and predicting cache performance. The intrinsic data locality of a particular application or workload can be measured in a microarchitectureindependent manne,: The data resulting from these measurements ideally can be used to develop an analytic model forpredicting memory performance on different cache sizes a...

GPU Computing: CUDA vs. OpenCL Currently there is no clear standard for the programming model in applications involving graphics processing units (GPUs). Nvidia as one of the most important hardware manufacturers is pushing their C language extension CUDA, while AMD/ATI as their competitor is following the general OpenCL framework that in principle allows to be applied for arbitrary accelerator...

We study the phase space of spatially homogeneous and isotropic cosmology in general scalar-tensor theories. A reduction to a two-dimensional phase space is performed when possible — in these situations the phase space is usually a twodimensional curved surface embedded in a three-dimensional space and composed of two sheets attached to each other, possibly with complicated topology. The result...

We study anisotropic cosmology in Hořava’s gravity theory and obtain Kasner type solutions, valid for any number d of spatial dimensions. The corresponding exponents satisfy two relations, one involving the marginal coupling λ . Also, Hořava’s (super)renormalisable theory predicts (super)stiff matter whose equation of state is p = wρ with w ≥ 1 . We discuss the implications of these results for...

We show that a number of problems of modern cosmology may be addressed and solved in the framework of multidimensional gravity with high-order curvature invariants, without invoking other fields. As applications of this approach, we mention primordial inflation and particle production after it; description of the modern accelerated stage of the Universe with stable compact extra dimensions; con...

This paper was written as part of a book entitled: “Questions of Modern Cosmology Galileo’s Legacy” which is a celebrative book dedicated to Galileo Galilei. The book is published in 2009, the International Year of Astronomy, since it is intended to be a modern tribute to the astronomer who, 400 years ago, first pointed a telescope towards the night sky. The book is written in the form of inter...

This essay tries to analyse the way in which Jesuit priest Giovanni Battista Riccioli (1598-1671) and his ideas were evaluated by traditional modern Historiographies, from seventeenth twentieth century, secular ecclesiastic ambiances Italy, having mind possibility of historical forgetfulness contribution this offered science century. For this, use Contextual, Historiographical Epistemological a...

My goal in Neuroscience journalism was It is my understanding that at that time, traverse a thin sheet of paper. But even to change the format of traditional most fields of Science held one, perhaps while they could, they did not develop the scientific journals, not by replacing them two journals in high esteem. If your paper photographic film below, which is rather but by offering a new format...
