Global Modeling of Secondary Organic Aerosol Formation from Aromatic Hydrocarbons: High- vs. Low-Yield Pathways
(European Geosciences Union, 2008)
Formation of SOA from the aromatic species toluene, xylene, and, for the first time, benzene, is added to a global chemical transport model. A simple mechanism is presented that accounts for competition between low and ...
Mining Wikipedia's Article Revision History for Training Computational Linguistics Algorithms
(AAAI Press, 2008)
We present a novel paradigm for obtaining large amounts of training data for computational linguistics tasks by mining Wikipedia's article revision history. By comparing adjacent versions of the same article, we extract ...
Amazon Rain Forest Subcanopy Flow and the Carbon Budget: Santarém LBA-ECO Site
(American Geophysical Union, 2008)
Horizontal and vertical CO<sub>2</sub> fluxes and gradients were made in an Amazon tropical rain forest, the Tapajós National Forest Reserve (FLONA-Tapajós: 54°58′W, 2°51′S). Two observational campaigns in 2003 and 2004 ...
Resolving systematic errors in estimates of net ecosystem exchange of CO2 and ecosystem respiration in a tropical forest biome
(Elsevier, 2008)
The controls on uptake and release of CO<sub>2</sub> by tropical rainforests, and the responses to a changing climate, are major uncertainties in global climate change models. Eddy-covariance measurements potentially provide ...
Off-Fault Plasticity and Earthquake Rupture Dynamics: 2. Effects of Fluid Saturation
(American Geophysical Union, 2008)
We present an analysis of inelastic off-fault response in fluid-saturated material during earthquake shear rupture. The analysis is conducted for 2-D plane strain deformation using an explicit dynamic finite element ...
Earthquake Slip Between Dissimilar Poroelastic Materials
(American Geophysical Union, 2008)
A mismatch of elastic properties across a fault induces normal stress changes during spatially nonuniform in-plane slip. Recently, Rudnicki and Rice showed that similar effects follow from a mismatch of poroelastic properties ...
Possible Mechanisms for Glacial Earthquakes
(American Geophysical Union, 2008)
The large glacial earthquakes reported on by Ekström et al. (2003, 2006) and Tsai and Ekström (2007) have previously been evaluated in terms of their seismic characteristics. In this paper we attempt to take constraints ...
M-DPOP: Faithful Distributed Implementations of Efficient Social Choice Problems
(AAAI Press, 2008)
In the efficient social choice problem, the goal is to assign values, subject to side constraints, to a set of variables to maximize the total utility across a population of agents, where each agent has private information ...
Plasmid Segregation: Is a Total Understanding Within Reach?
(Elsevier, 2008)
Recent in vitro and in vivo studies of the proteins responsible for the active partitioning of bacterial plasmids suggest that it will be possible to develop a quantitative, molecular understanding of this form of DNA segregation.
Variations of \(O_3\) and CO in Summertime at a Rural Site Near Beijing
(Copernicus Publications on behalf of the European Geosciences Union, 2008)
Large intra-season differences in mixing ratios of CO and \(O_3\) were detected at Miyun, a rural site north of Beijing, in summer 2006. Despite an increase in mean daytime mixing ratio of CO from 500 ppbv in June to 700 ...
