GPS radio occultation: Results from CHAMP, GRACE and FORMOSAT-3/COSMIC
(2009)Terrestrial, Atmospheric and Oceanic SciencesThe Taiwan/US FORMOSAT-3/COSMIC (FORMOsa SATellite mission - 3/Constellation Observing System for Meteorology, Ionosphere and Climate) satellite nstellation was successfully launched on 14 April 2006. It is expected to leverage the use of the GPS (Global Positioning System) radio occultation data for atmospheric and ionospheric research to improve global weather forecasts and aid climate change related studies. FORMOSAT-3/COSMIC, together ...Journal Article -
A Computationally Efficient Method for Polyphonic Pitch Estimation
(2009)EURASIP Journal on Advances in Signal ProcessingThis paper presents a computationally efficient method for polyphonic pitch estimation. The method employs the Fast Resonator Time-Frequency Image (RTFI) as the basic time-frequency analysis tool. The approach is composed of two main stages. First, a preliminary pitch estimation is obtained by means of a simple peak-picking procedure in the pitch energy spectrum. Such spectrum is calculated from the original RTFI energy spectrum according ...Journal Article -
Punishment Deters Crime Because Humans Are Bounded in Their Strategic Decision-Making
(2009)Journal of Artificial Societies and Social SimulationIs it rational to reduce criminal activities if punishments are increased? While intuition might suggest so, game theory concludes differently. From the game theoretical perspective, inspectors anticipate the effect of increased punishments on criminal behavior and reduce their inspection activities accordingly. This implies that higher punishments reduce inspections and do not affect crime rates. We present two laboratory experiments, ...Journal Article -
How Groups Can Foster Consensus: The Case of Local Cultures
(2009)Journal of Artificial Societies and Social SimulationA local culture denotes a set of rules on business behaviour among firms in a cluster. Similar to social norms or conventions, it is an emergent feature of interaction in an economic network. To model its emergence, we consider a distributed agent population, representing cluster firms. Further, we build on a continuous opinion dynamics model with bounded confidence (ε), which assumes that two agents only interact if differences in their ...Journal Article -

The SCOUT-O3 Darwin Aircraft Campaign: rationale and meteorology
(2009)Atmospheric Chemistry and PhysicsAn aircraft measurement campaign involving the Russian high-altitude aircraft M55 Geophysica and the German DLR Falcon was conducted in Darwin, Australia in November and December 2005 as part of the European integrated project SCOUT-O3. The overall objectives of the campaign were to study the transport of trace gases through the tropical tropopause layer (TTL), mechanisms of dehydration close to the tropopause, and the role of deep ...Journal Article -
Effectiveness of Active-Online, an Individually Tailored Physical Activity Intervention, in a Real-Life Setting: Randomized Controlled Trial
(2009)Journal of Medical Internet ResearchBackground: Effective interventions are needed to reduce the chronic disease epidemic. The Internet has the potential to provide large populations with individual advice at relatively low cost. Objective: The focus of the study was the Web-based tailored physical activity intervention Active-online. The main research questions were (1) How effective is Active-online, compared to a nontailored website, in increasing self-reported and ...Journal Article -
Seryl-tRNA Synthetases: Enzymes with Multiple Personalities
(2009)Croatica Chemica ActaSeryl-tRNA synthetases (SerRS) are essential enzymes responsible for aminoacylation of cognate transfer-RNAs (tRNAsSer) with serine, which is then incorporated into the proteins being synthesized on the ribosome. Although tRNA synthetases are usually a very conserved class of enzymes, phylogenic analyses revealed the existence of two distinct types of serine-charging enzymes; a standard or bacterial-type SerRS is found in the majority of ...Journal Article
