Hydrological real-time modeling using remote sensing data
(2010)Hydrology and Earth System SciencesReliable real-time forecasts of the discharge canprovide valuable information for the management of a riverbasin system. For the management of ecological releaseseven discharge forecasts with moderate accuracy can be be-neficial. Sequential data assimilation using the Ensemble Kalman Filter provides a tool that is both efficient and robustfor a real-time modelling framework. One key parameter in ahydrological system is the soil moisture, ...Journal Article -
A preliminary early-season flower- visitation web for the Kirindy forest, Madagascar
(2010)Journal of Pollination EcologyTropical dry deciduous forest is an endangered ecosystem whose plant-pollinator relationships are little known. We characterised a portion of the web of interactions between flowering plants and flower visitors in the Kirindy Forest of the Menabe region of west-central Madagascar. Taking a plant-centered approach, we observed individuals of the 5 most abundant native plant species that were coming into flower at the end of the annual dry ...Journal Article -
Neutron Optical Beam Splitter from Holographically Structured Nanoparticle-Polymer Composites
(2010)Physical Review LettersWe report a breakthrough in the search for versatile diffractive elements for cold neutrons. Nanoparticles are spatially arranged by holographical means in a photopolymer. These grating structures show remarkably efficient diffraction of cold neutrons up to about 50% for effective thicknesses of only 200μm. They open up a profound perspective for next generation neutron-optical devices with the capability to tune or modulate the neutron ...Journal Article -
Analysis of intra-country virtual water trade strategy to alleviate water scarcity in Iran
(2010)Hydrology and Earth System SciencesIncreasing water scarcity has posed a major constraint to sustain food production in many parts of the world. To study the situation at the regional level, we took Iran as an example and analyzed how an intra-country "virtual water trade strategy" (VWTS) may help improve cereal production as well as alleviate the water scarcity problem. This strategy calls, in part, for the adjustment of the structure of cropping pattern (ASCP) and ...Journal Article -
Synthesis and Structure of Geometric Isomers of 1-[(methoxyimino)ethyl]- ferrocene and Methyl 1'-[(methoxyimino)ethyl]ferrocene-1-carboxylate
(2010)Croatica Chemica ActaHere we report synthesis, spectral data and single-crystal X-ray molecular and crystal structures of (E)-1-[(methoxyimino)ethyl] ferrocene (2) and (E)-methyl 1'-[(methoxyimino)ethyl]ferrocene-1- carboxylate (4). These organometallics are recognized as precursors for optically pure (1- ferrocenylethyl)amine (Fea) and 1'-(1-aminoethyl)ferrocene-1-carboxylic acid (Fcca) derivatives. The (E/Z)mixtures of the title compounds 2 and 4 were ...Journal Article -
Adaptively smoothed seismicity earthquake forecasts for Italy
(2010)Annals of GeophysicsWe present a model for estimation of the probabilities of future earthquakes of magnitudes m ≥ 4.95 in Italy. This model is a modified version of that proposed for California, USA, by Helmstetter et al. [2007] and Werner et al. [2010a], and it approximates seismicity using a spatially heterogeneous, temporally homogeneous Poisson point process. The temporal, spatial and magnitude dimensions are entirely decoupled. Magnitudes are independently ...Journal Article -
Simple smoothed seismicity earthquake forecasts for Italy
(2010)Annals of GeophysicsSeveral earthquake forecast experiments in Italy have been initiated within the European testing center of the global Collaboratory for the Study of Earthquake Predictability. In preparation for these experiments, we developed space-rate-magnitude forecasts based on a simple model that incorporates the spatial clustering of the seismicity. This model, which we call the simple smoothed seismicity model (TripleS), has a minimal number of ...Journal Article -
Asperity-based earthquake likelihood models for Italy
(2010)Annals of GeophysicsThe Asperity Likelihood Model (ALM) hypothesizes that small-scale spatial variations in the b-value of the Gutenberg-Richter relationship have a central role in forecasting future seismicity. The physical basis of the ALM is the concept that the local b-value is inversely dependent on the applied shear stress. Thus low b-values (b <0.7) characterize locked patches of faults, or asperities, from which future mainshocks are more likely to ...Journal Article -
Retrospective evaluation of the five-year and ten-year CSEP-Italy earthquake forecasts
(2010)Annals of GeophysicsOn August 1, 2009, the global Collaboratory for the Study of Earthquake Predictability (CSEP) launched a prospective and comparative earthquake predictability experiment in Italy. The goal of this CSEP-Italy experiment is to test earthquake occurrence hypotheses that have been formalized as probabilistic earthquake forecasts over temporal scales that range from days to years. In the first round of forecast submissions, members of the ...Journal Article -
