چکیده
Cloud computing aims to give users virtually unlimited pay-per-use computing resources without the burden of managing the underlying infrastructure. We claim that, in order to realize the full potential of cloud computing, the user must be presented with a pricing model that offers flexibility at the requirements level, such as a choice between different degrees of execution speed, and the cloud provider must be presented with a programming model that offers flexibility at the execution level, such as a choice between different scheduling policies. In this paper, we present a framework called FlexPRICE (Flexible Provisioning of Resources in a Cloud Environment) where for each job, the user purchases a virtual computer with the desired speed and cost characteristics, and the cloud provider optimizes the utilization of resources across a stream of jobs from different users.

The extracellular loops of Smoothened play a regulatory role in control of Hedgehog pathway activation.
The Hedgehog (Hh) signaling pathway plays an instructional role during development, and is frequently activated in cancer. Ligand-induced pathway activation requires signaling by the transmembrane protein Smoothened (Smo), a member of the G-protein-coupled receptor (GPCR) superfamily. The extracellular (EC) loops of canonical GPCRs harbor cysteine residues that engage in disulfide bonds, affect...
متن کاملIntrinsic circuit organization and theta-gamma oscillation dynamics in the entorhinal cortex of the rat.
A thorough knowledge of the intrinsic circuit properties of the entorhinal cortex (EC) and the temporal dynamics these circuits support is essential for understanding how information is exchanged between the hippocampus and neocortex. Using intracellular and extracellular recordings in the anesthetized rat and anatomical reconstruction of single cells, we found that EC5 and EC2 principal neuron...
متن کاملCrystal structures of Drosophila N-cadherin ectodomain regions reveal a widely used class of Ca2þ-free interdomain linkers
Vertebrate classical cadherins mediate selective calcium-dependent cell adhesion by mechanisms now understood at the atomic level. However, structures and adhesion mechanisms of cadherins from invertebrates, which are highly divergent yet function in similar roles, remain unknown. Here we present crystal structures of threeand four-tandem extracellular cadherin (EC) domain segments from Drosoph...

متن کاملDifferent characteristics of char and soot in the atmosphere and their ratio as an indicator for source identification in Xi’an, China
Numerous definitions and analytical techniques for elemental (or black) carbon (EC) have been published in the scientific literature, but still no generally accepted interdisciplinary definition exists. EC is not a single chemical compound, but is mainly composed of two parts of carbon contents: combustion residues from pyrolysis and combustion emissions formed via gas-to-particle conversion. A...
