Secondary organic aerosol (SOA) accounts for a significant fraction of ambient tropospheric aerosol and a detailed knowledge of the formation, properties and transformation of SOA is therefore required to evaluate its impact on atmospheric processes, climate and human health. The chemical and physical processes associated with SOA formation are complex and varied, and, despite considerable prog...

[1] The volatility basis set, a computationally efficient framework for the description of organic aerosol partitioning and chemical aging, is implemented in the Goddard Institute for Space Studies General Circulation Model II′ for a coupled global circulation and chemical transport model to simulate secondary organic aerosol (SOA) formation. The latest smog chamber information about the yields...

The Service-Oriented Architecture (SOA) model has become the cornerstone of business computing. Its ability to greatly accelerate the development of business-critical applications promotes business agility, decreases time-to-value and total cost of ownership (TCO), and greatly increases the efficiency and strategic value of IT. Beyond mere application development, it has become the favored appr...

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 high-yield pathways of SOA formation, wherein secondary gas-phase products react further with either nitric oxide (NO) or hydroperoxy radical (HO2) to yield semior non-volatile p...

This work presents a systematic investigation of the molecular level composition and the extent of aqueous photochemical processing in different types of secondary organic aerosol (SOA) from biogenic and anthropogenic precursors including α-pinene, β-pinene, β-myrcene, d-limonene, α-humulene, 1,3,5-trimethylbenzene, and guaiacol, oxidized by ozone (to simulate a remote atmosphere) or by OH in t...

For interactions to be possible within the Service Oriented Architecture (SOA) ecosystem, each actor must be enough confident of other actors to engage safely in the interactions. Therefore, the establishing of objective metrics tailored to the context of SOA that show security of a system and lead to enhancements is very attractive. The purpose of our paper is to present a GQM (Goal Question M...

The migration to a Service Oriented Architecture (SOA) is a complex undertaking in terms of aligning business and IT concerns as well as analysis of technical aspects. Conceptual modeling can be helpful for supporting SOA migration by (1) bridging the gap between business and IT concerns, and (2) analyzing the as-is and to-be IT infrastructures. We contribute language requirements derived from ...

We describe Onto⇔SOA – an approach to integrate ontologies and Service-Oriented Architectures (SOA) to provide a simple yet effective mechanism for representing and exploiting both conceptual and behavioral domain aspects. We interpret SOA as an architectural style constrained to induce the domain alignment and loose coupling characteristics on a compliant architecture. By introducing ontologie...

Hemispheric contributions to lexical-semantic processing were investigated using event-related potentials and a divided visual field semantic priming paradigm. Hemispheric activation for pairs related via semantic category membership and association (CA) or via semantic category membership only (CO) was examined over two stimulus onset asynchronies (SOAs). Experiment 1 employed a SOA of 250 ms,...

We investigated the role of implicit spatiotemporal learning in the Posner spatial cueing of attention task. During initial training, the proportion of different trial types was altered to produce a complex pattern of spatiotemporal contingencies between cues and targets. For example, in the short invalid and long valid condition, targets reliably appeared either at an uncued location after a s...
