In the near future, many personal electronic devices will be able to communicate with each other over a short range wireless channel. We investigate

Given a snapshot of a social network, can we infer which new interactions among its members are likely to occur in the near future? We formalize this question as the link-prediction problem, and we develop approaches to link prediction based on measures for analyzing the “proximity” of nodes in a

Abstract. This paper summarize the present status and near term perspectives for Diffractive Physics at Tevatron. We describe the new detectors that are being installed around the CDF and DØ interaction regions, and discuss the physics topics accessible in view of these upgrades. 1

[1] Global tropospheric ozone distributions, budgets, and radiative forcings from an ensemble of 26 state-of-the-art atmospheric chemistry models have been intercompared and synthesized as part of a wider study into both the air quality and climate roles of ozone. Results from three 2030 emissions scenarios, broadly representing ‘‘optimistic,’’ ‘‘likely,’ ’ and ‘‘pessimistic’ ’ options, are compared to a base year 2000 simulation. This base case realistically represents the current global distribution of tropospheric ozone. A further set of simulations considers the influence of climate change over the same time period by forcing the central emissions scenario with a surface warming of around 0.7K. The use of a large multimodel ensemble allows us to identify key areas of uncertainty and improves the robustness of the results. Ensemble mean changes in tropospheric ozone burden between 2000 and 2030 for the 3 scenarios range from a 5 % decrease, through a 6 % increase, to a 15 % increase. The intermodel uncertainty (±1 standard deviation) associated with these values is about ±25%. Model outliers have no significant influence on the ensemble mean results. Combining ozone and methane changes, the three scenarios produce radiative forcings of 50, 180, and 300 mW m 2, compared to a CO2 forcing

Although the deep-sea appears remote from human activities, a variety of anthropogenic forcing factors already impact deep seafloor communities, and these impacts will increase in the near future.
