Within the global framework of the climate change, according to most Regional Climate Mod-els the maximum peak discharges in river will increase in importance and frequency. Therefore the people will have to face worst inundation conditions. In order to protect themselves from the increasing flood risk, the communities have to draw up suitable flood protection measures. The selection and the evaluation among the different possible flood mitigation measures requires developing decision-support system (DSS). This sys-tem has to take into consideration parameters such as hydraulic, economic, social or environmental. This pa-per focuses on the integration between two components of the DSS, namely the evaluation of the economic impacts of floods and the hydrodynamic modelling. The hydraulic simulations are conducted by means of WOLF 2D flow modelling system and provide as an output high resolution flood maps detailing the distribu-tion of water depth and flow velocity in the floodplains. The integration is ensured by the use of very accurate geographic databases and an automated procedure which makes the most of geomatic methods. The paper de-tails the application of the integrated assessment procedure for a case study along the river Ourthe located in the Meuse basin (Belgium). Moreover, possibilities of validation of the economic damage evaluation proce-dure are investigated by comparing computation results with real damage data recorded by the Belgian Disas-ter Fund after several major flood events (2003, 2002, 1995, and 1993).

In the frame of the Interreg IV project “MICROBIOMED”, the Centre Spatial de Liège (CSL) participated to the development of an original concept of plasmonic-related instrumentation platform dedicated to diagnostic biosensing tests out of the laboratory. The developed instrumental platform includes both disposable one-use microfluidic affinity biochip and compact optical readout device for biochip monitoring involving mobile Internet devices for data processing and communication. The biochip includes both microfluidic and optical coupling structures formed into a single plastic slab (see Fig. 1). The microfluidic path of the biochip operates in passive capillary pumping mode. The optical detection part involves Surface Plasmon Resonance phenomenon. An essential advantage of the developed biochip is that its implementation involves conventional hot embossing and thin film deposition process, perfectly suited for mass production of low-cost microfluidic biochip for biochemical applications. In this presentation we focus on the fabrication of the fluidic channels and capillary structures with a commercial excimer laser mask projection system working at 193 nm. Micro-pillars of 25μm width for the capillary pump as in Fig. 1 have been ablated in the PMMA master slab used for the replication chain of the biochip prototype. By simply changing the pattern on the motorized mask, micro-pillars from 10µm to 50 µm diameter have been also machined successfully in PMMA and even glass. The mask is made of a structured metallic thin layer deposited on a quartz substrate and prepared at CSL by direct writing laser technique. The excimer laser mask projection technique allows ablating several tens of µpillars per second in the field of view of the laser beam. The entire micro-pillars area of the biochip master is then performed by a simple step and repeat laser process. The topography and dimensions of the µstructures have been measured by SEM and interferometric optical profilometry. The dynamic hydrophilic behavior of a liquid drop on the micro-pillars structure has been monitored with the camera of a contact angle instrument. [less ▲]

The aim of this study was to test the integration of external information, i.e. foreign estimated breeding values (EBV) and the associated reliabilities (REL), for stallions into the Belgian genetic evaluation for jumping horses. The Belgian model is a bivariate repeatability Best Linear Unbiased Prediction animal model only based on Belgian performances while Belgian breeders import horses from neighbouring countries. Thereby, use of external information is needed as prior to achieve more accurate EBV. Pedigree and performance data contained 101,382 horses and 712,212 performances, respectively. After conversion to the Belgian trait, external information of 98 French and 67 Dutch stallions were integrated into the Belgian evaluation. Resulting Belgian rankings of the foreign stallions were more similar to foreign rankings according to the increase of the rank correlations of at least 12%. REL of their EBV were improved of at least 2% on average. External information was partially to totally equivalent to 4 years of contemporary horses’ performances or to all the stallions’ own performances. All these results showed the interest to integrate external information into the Belgian evaluation. [less ▲]

One of the most important theoretical assumptions of methods used to assess genetic values is that all available information has to be considered simultaneously to obtain unbiased estimates. However, the widespread international exchange of genetic material and, more recently, the important development of the genomic selection lead to the coexistence of different genetic evaluations. Therefore, the blending of the different sources of information is necessary to achieve better prediction. Integration of external information into genetic evaluations by a Bayesian procedure can partially resolve the problem under some assumptions. Results from such a method that also avoids double counting among external animals are highly similar to those from a joint evaluation. [less ▲]

Hatcheries, input dealers, farmers, collectors and processors are the primary actors of shrimp value chain in the Mekong River Delta (MRD) Vietnam, a sector that has many problems of disease, shrimp seed, environmental pollution, and management skills. Holding the strongest power in the shrimp value chain, the processors determine shrimp prices and set up requirements of shrimp quality and size in the market though quality control has not been completely implemented due to the limitations of financial capital, knowledge, awareness, as well as the quality of raw material supplied by collectors and farmers. Farmers stayed in the weakest position in the chain due to their small individual scale, and low skills. The results of the study show that most of the shrimp farmers stay out of vertical integration under farming contracts while the rest joined in the game without success. Contract farming seems not for small scale farmers who account for a large part in the MRD, and not interesting for producers who get success with their cultivation. Farmers prefer a non-contract option due to non-transparency of interest share as well as cost account. Food safety standards, decision No. 80/2002/QĐ-TTg, culture, trust, government structure, credit support and corruption are the main factors affecting farmers’ integration chances. Floor price mechanism, risk sharing, small scale of the model of vertical integration and excess suppliers in the market, administrative misconception and inefficient public management are the main reasons of failures of contract farming of two case studies in the MRD. Planning and projection of shrimp production zones are therefore the priority matters to address. Furthermore, re-organizing shrimp farmers into legal teams or groups or cooperatives is also necessary to increase the size of the existing shrimp cultivation units in Vietnam in order to improve the sector.

The aim of this study was to test the integration of foreign estimated breeding values (EBV) for stallions into the Belgian genetic evaluation for jumping horses. Belgian breeders import horses from neighbouring countries for which foreign information is needed as prior to estimate a more accurate EBV. The Belgian model is a bivariate repeatability BLUP animal model. For the year 2009, pedigree and data files contained 101 382 horses and 712 212 performances. 98 French and 67 Dutch stallions were selected and their foreign EBVs were converted into Belgian national trait. Associated reliabilities were also estimated. A Bayesian approach (Legarra et al., 2007) was applied to integrate this prior information into the Belgian evaluation. It led to a slight modification of the average EBV and of the standard deviation for the whole population. It also led to a new Belgian ranking of the foreign stallions more similar to foreign rankings. However, the adequacy of the Belgian model was not damaged. With regards to prediction ability, Bayesian evaluations using conversion equation estimated by Weighted Least Squares procedure predicted the best traditional EBVs of the year 2009 for the French stallions. For the Dutch ones, it were the evaluations associated to the conversion equation based on Wilmink et al. (1986). For both countries, Bayesian evaluations using conversion equation based on Goddard (1985) improved the most the stability of EBVs. Finally, integration of French and Dutch information improved reliabilities of the Bayesian EBVs of at least 5% and 2% for French and Dutch stallions, respectively. These results confirm the interest to integrate foreign information into the Belgian evaluation for jumping horses. [less ▲]

The aim of this study was to test the integration of foreign breeding values for stallions into the Belgian genetic evaluation of jumping horses. Belgian breeders import horses from neighbouring countries for which foreign information is needed as prior to estimate a more accurate breeding value. The Belgian model is a bivariate repeatability BLUP animal model. For the year 2009, pedigree and data files provided by the Catholic University of Leuven contained 101 382 horses and 712 212 performances. 98 French and 67 Dutch stallions were selected and their foreign estimated breeding values had to be converted into Belgian national trait. Also, the associated reliabilities had to be estimated. Then, this prior information was integrated into the Belgian evaluation using a Bayesian approach. It led to a slight modification of the average estimated breeding value and of the standard deviation for the whole population. It also led to a new Belgian ranking of the foreign stallions more similar to foreign rankings. However, despite these modifications, the adequacy of the Belgian model was not damaged. Within regards to prediction ability, Bayesian evaluations using the conversion equation estimated by the Weighted Least Squares procedure predicted the best traditional estimated breeding values of the year 2009 for the French stallions. For the Dutch ones, it were the evaluations associated to the Wilmink‟s conversion equation. For both countries, Bayesian evaluations using Goddard‟s conversion method improved most the stability of breeding values. Finally, integration of French and Dutch information improved reliabilities of the Bayesian estimated breeding values. [less ▲]

In this paper, we address the problem of transporting vital commodities and emergency personnel during the response stage of a disaster relief operation by integrating fuzzy linear optimization and the principles of scenario analysis. We treat this transportation system as a probabilistic multi-commodity multi-modal network flow problem and first develop a fuzzy model that allows the satisfaction of demand requirements through different supply nodes over a fuzzy network. Since the available information in case of disasters is generally vague and imprecise about the values of model parameters, fuzzy linear optimization is employed to deal with this uncertainty and to generate different scenarios depending upon the preferences of the decision maker. Then these scenarios are handled within the framework of the scenario analysis by defining a scenario as a joint realization of the uncertain parameters. Here, scenario analysis method can be considered as a search for a robust solution that guarantees the maximum satisfaction of demands with the minimum transportation cost. [less ▲]

This study analyzes the problem of transporting vital commodities and emergency personnel during the response stage of a disaster relief operation by integrating fuzzy linear optimization and stochastic programming. This transportation system is treated as a probabilistic, multi-commodity, multi-modal network flow problem and first a fuzzy model that allows the satisfaction of demand requirements through different supply nodes over a fuzzy network is developed. Since the available information in case of disasters is generally vague and imprecise about the values of model parameters, fuzzy linear optimization is employed to deal with this uncertainty and to generate different scenarios depending upon the preferences of the decision maker. Then these scenarios are handled within the framework of stochastic programming by defining a scenario as a joint realization of the uncertain parameters. Multi-commodity network flow problem is decomposed into uncapacitated single-commodity network flow problems by using Lagrangian relaxation. An exact algorithm is developed for each subproblem, and a sequential structure is designed to maintain consistency and feasibility between the solutions of these subproblems. [less ▲]

The vast amount of heterogeneous omics data, encompassing a broad range of biomolecular information, requires novel methods of analysis, including those that integrate the available levels of information. In this work we describe Regression2Net, a computational approach that is able to integrate gene expression and genomic or methylome data in two steps. First, penalized regressions are used to build Expression-Expression (EEnet) and Expression-Genome or –Methylome (EMnet) networks. Second, network theory is used to highlight important communities of genes. When applying our approach Regression2Net to gene expression and methylation profiles for individuals with glioblastoma multiforme, we identified respectively 284 and 447 potentially interesting genes in relation to glioblastoma pathology. These genes showed at least one connection in the integrated networks ANDnet and XORnet derived from aforementioned EEnet and EMnet networks. Whereas the edges in ANDnet occur in both EEnet and EMnet, the edges in XORnet occur in EMnet but not in EEnet. In-depth biological analysis of connected genes in ANDnet and XORnet revealed genes that are related to energy metabolism, cell cycle control (AATF), immune system response and several cancer types. Importantly, we observed significant over-representation of cancer related pathways including glioma, especially in the XORnet network, suggesting a non-ignorable role of methylation in glioblastoma multiforma. In the ANDnet, we furthermore identified potential glioma suppressor genes ACCN3 and ACCN4 linked to the NBPF1 neuroblastoma breakpoint family, as well as numerous ABC transporter genes (ABCA1, ABCB1) suggesting drug resistance of glioblastoma tumors.
