An Introduction to the Five‐Factor Model and Its Applications
ABSTRACT The five‐factor model of personality is a hierarchical organization of personality traits in terms of five basic dimensions: Extraversion, Agreeableness, Conscientiousn...
Nonionic Triblock and Star Diblock Copolymer and Oligomeric Surfactant Syntheses of Highly Ordered, Hydrothermally Stable, Mesoporous Silica Structures
A family of highly ordered mesoporous (20−300 Å) silica structures have been synthesized by the use of commercially available nonionic alkyl poly(ethylene oxide) (PEO) oligomeri...
Intelligent agents: theory and practice
Abstract The concept of an agent has become important in both artificial intelligence (AT) and mainstream computer science. Our aim in this paper is to point the reader at what ...
Bounding the role of black carbon in the climate system: A scientific assessment
Abstract Black carbon aerosol plays a unique and important role in Earth's climate system. Black carbon is a type of carbonaceous material with a unique combination of physical ...
The<i>Gaia</i>mission
Gaia is a cornerstone mission in the science programme of the EuropeanSpace Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the origin...
Effects of Clopidogrel in Addition to Aspirin in Patients with Acute Coronary Syndromes without ST-Segment Elevation
The antiplatelet agent clopidogrel has beneficial effects in patients with acute coronary syndromes without ST-segment elevation. However, the risk of major bleeding is increase...
Thrombolysis with Alteplase 3 to 4.5 Hours after Acute Ischemic Stroke

Consensus seeking in multiagent systems under dynamically changing interaction topologies
This note considers the problem of information consensus among multiple agents in the presence of limited and unreliable information exchange with dynamically changing interacti...
Biofilms: Survival Mechanisms of Clinically Relevant Microorganisms
SUMMARY Though biofilms were first described by Antonie van Leeuwenhoek, the theory describing the biofilm process was not developed until 1978. We now understand that biofilms ...
Brain magnetic resonance imaging with contrast dependent on blood oxygenation.
Paramagnetic deoxyhemoglobin in venous blood is a naturally occurring contrast agent for magnetic resonance imaging (MRI). By accentuating the effects of this agent through the ...
