The Aurora and Borealis Stream Processing Engines

Over the last several years, a great deal of progress has been made in the area of stream-processing engines (SPEs) [9, 11, 17]. Three basic tenets distinguish SPEs from current data processing engines. First, they must support primitives for streaming applications. Unlike Online Transaction Processing (OLTP), which processes messages in isolation, streaming applications entail time series oper...

Aurora borealis wraps Plk1 and CDK together

Proper execution of mitosis requires the phosphorylation of hundreds of functional proteins by multiple protein kinases. Activation and inactivation of these kinases needs to be coordinated so that the correct order and timing of mitotic events allows faithful chromosome inheritance. The intrinsic oscillation of one of these kinases, the cyclin-dependent kinase (CDK), has been shown to be compo...

Aurora Borealis: Stochastic Cellular Automata Simulations of the Excited-State Dynamics of Oxygen Atoms

Emissions from the 1S and 1D excited states of atomic oxygen play a Ž . prominent role in creating the dramatic light displays aurora borealis seen in the skies over polar regions of the Northern Hemisphere. A probabilistic asynchronous cellular w automaton model described previously Seybold, Kier, and Cheng, J Phys Chem 1998, x 102, 886]891 has been applied to the excited-state dynamics of ato...

FDI & Growth : What Causes What ?

The paper examines the causal relationship between FDI and economic growth by using an innovative econometric methodology to study the direction of causality between the two variables. We apply our methodology, based on the Toda-Yamamoto test for causality, to time-series data covering the period 19692000 for three developing countries, namely Chile, Malaysia and Thailand, all of them major rec...

What Causes Eye Pain?

Eye pain is an unpleasant sensory and emotional experience including sensory-discriminative, emotional, cognitive, and behavioral components and supported by distinct, interconnected peripheral and central nervous system elements. Normal or physiological pain results of the stimulation by noxious stimuli of sensory axons of trigeminal ganglion (TG) neurons innervating the eye. These are functio...
