Some Joules Are More Precious Than Others: Managing Renewable Energy in the Datacenter∗
Large cloud-computing datacenters now host a wide range of business applications, ranging from e-commerce websites to search engines to data mining. Increasingly, these datacenters use renewable energy from wind turbines or solar panels to reduce their dependence on costly and less clean energy from the grid [17, 4, 1]. This paper argues that datacenter management should be revised to maximize ...
متن کاملA platinum shell for ultraslow ligand exchange: unmodified DNA adsorbing more stably on platinum than thiol and dithiol on gold.
Due to the ultraslow ligand exchange rate on Pt, non-thiolated DNA is adsorbed on platinum nanoparticles (PtNPs) more stably than thiolated and even dithiolated DNA on AuNPs. Adsorption kinetics, capacity and stability are systematically compared as a function of DNA sequence. The Pt conjugates can tolerate extreme pH, salt, and thiol molecules. Taking advantage of the optical properties of AuN...
متن کاملPlatinum Anniversary: Virus and Lichen Alga Together More than 70 Years
Trebouxia aggregata (Archibald) Gärtner (phylum Chlorophyta, family Trebouxiaceae), a lichen symbiotic alga, has been identified as host of the well-known herbaceous plant virus Cauliflower mosaic virus (CaMV, family Caulimoviridae). The alga had been isolated from Xanthoria parietina more than 70 years ago and has been maintained in a collection since that time. The CaMV detected in this colle...
متن کاملPolynuclear platinum anticancer drugs are more potent than cisplatin and induce cell cycle arrest in glioma.
We have evaluated the efficacy of the multinuclear platinum chemotherapeutics BBR3464, BBR3571, and BBR3610 against glioma cells in culture and animal models and investigated their mechanism of action at the cellular level. In a clonogenic assay, BBR3610, the most potent compound, had an IC90 dose (achieving 90% colony formation inhibition) that was 250 times lower than that of cisplatin for bo...
متن کاملMore hype than HOPE.
More Hype Than HOPE To the Editor: In the recently published Heart Outcomes Prevention Evaluation (HOPE study),1 treatment with the ACE inhibitor ramipril was reported to reduce cardiovascular morbidity and mortality independent of blood pressure (BP) reduction. High-risk “normotensive” (BP 140/80 mm Hg) patients (n 9541) were randomized to receive either 10 mg of ramipril or placebo in additio...
