Mastitis remains the most important health issue in dairy cattle. Improved methods to identify cows developing subclinical mastitis would benefit farmers. We herein describe a novel method to determine the somatic cell counts (SCC) of individual cows by bulk genotyping a sample of milk from the milk tank with panels of genome-wide single nucleotide polymorphisms (SNP). We developed a simple linear model to estimate the contribution of individual cows to the genomic DNA present in the tank milk from 1) the known genotypes of individual cows for the interrogated SNP and 2) the ratio of SNP alleles in the tank milk. Using simulations, we estimate that 3,000, 50,000, and 700,000 SNP are sufficient to accurately (R(2)>0.98) estimate individual SCC in tanks containing milk from 25, 100, and 500 cows, respectively. Using actual data, we demonstrate that the SCC of 21 cows can be estimated with a coefficient of determination of 0.60 using approximately 9,000 SNP. The proposed method increases the value of the proposition of SNP genotyping individual cows for genomic selection purposes. [less ▲]

The bacteria that cause cholera are known to be normal inhabitants of surface water, however, the environmental risk factors for different biotypes of cholera are not well understood. This study identifies environmental risk factors for cholera in an endemic area of Bangladesh using a geographic information systems (GIS) approach. The study data were collected from a longitudinal health and demographic surveillance system and the data were integrated within a geographic information system database of the research area. Two study periods were chosen because they had different dominant biotypes of the disease. From 1992 to 1996 El Tor cholera was dominant and from 1983 to 1987 classical cholera was dominant. The study found the same three risk factors for the two biotypes of cholera including proximity to surface water, high population density, and poor educational level. The GIS database was used to measure the risk factors and spatial filtering techniques were employed. These robust spatial methods are offered as an example for future epidemiological research efforts that define environmental risk factors for infectious diseases. (C) 2002 Elsevier Science Ltd.

Plantae (Archaeplastida) are a natural group of organisms with plastids of primary endosymbiotic origin. Within this group, members of the red algae show evidence of a reduction of their genomic content. In this work, we designed a bioinformatics approach to investigate the few, sometimes incomplete, genomic datasets available for red algae, with the purpose of pointing out possible gene family losses and expansions. Our pipeline first populates a relational database with precomputed orthology relationships between green plant genomes and red algal datasets and then efficiently queries the database for computing statistics of losses and expansions for a series of gene families of interest.

An implementation of the event tree approach is proposed to determine possible sequences of cascading failures with severe impact on a given power system. The algorithm takes into account protection systems hidden failures and transmission system equipments overload. At each level of the event tree development, the sequence probability order is computed and a filtering tool is used to identify possible harmful sequence. These are furthermore analysed with a time domain simulation tool in order to assess their impact on the power system. This paper contains the description of the event tree algorithm as well as examples of its practical application on the Nordic32 test system. [less ▲]

Objectives:Recent fMRI studies have shown that it is possible to reliably identify the default-mode network (DMN) in the absence of any task, by resting-state connectivity analyses in healthy volunteers. We here aimed to identify the DMN in the challenging patient population of disorders of consciousness encountered following coma. Experimental design: A spatial independent component analysis-based methodology permitted DMN assessment, decomposing connectivity in all its different sources either neuronal or artifactual. Three different selection criteria were introduced assessing anticorrelation-corrected connectivity with or without an automatic masking procedure and calculating connectivity scores encompassing both spatial and temporal properties. These three methods were validated on 10 healthy controls and applied to an independent group of 8 healthy controls and 11 severely brain-damaged patients [locked-in syndrome (n = 2), minimally conscious (n = 1), and vegetative state (n = 8)]. Principal observations: All vegetative patients showed fewer connections in the default-mode areas, when compared with controls, contrary to locked-in patients who showed near-normal connectivity. In the minimally conscious-state patient, only the two selection criteria considering both spatial and temporal properties were able to identify an intact right lateralized BOLD connectivity pattern, and metabolic PET data suggested its neuronal origin. Conclusions: When assessing resting-state connectivity in patients with disorders of consciousness, it is important to use a methodology excluding non-neuronal contributions caused by head motion, respiration, and heart rate artifacts encountered in all studied patients.

he introduction of new public transport systems can influence society in a multitude of ways ranging from modal choices and the environment to economic growth. This paper examines the determinants of light rail mode choice for medium- and long-distance trips (10 to 40 km) for a new light rail system in Flanders, Belgium. To investigate these choices, the effects of various transport system-specific factors (i.e., travel cost, in-vehicle travel time, transit punctuality, waiting time, access and egress time, transfers, and availability of seats) as well as the travelers' personal traits were analyzed by using an alternating logistic regression model, which explicitly takes into account the correlated responses for binary data. The data used for the analysis stem from a stated preference survey conducted in Flanders. The modeling results are in line with literature: most transport system-specific factors as well as socioeconomic variables, attitudinal factors, perceptions, and the frequency of using public transport contribute significantly to the preference for light rail transit. In particular, the results indicate that the use of light rail is strongly influenced by travel cost and in-vehicle travel time and to a lesser extent by waiting and access-egress time. Seat availability appeared to play a more important role than did transfers in deciding to choose light rail transit. The findings of this paper can be used by policy makers as a frame of reference to make light rail transit more successful. [less ▲]

The introduction of new public transport systems can influence society in a multitude of ways, ranging from modal choices and the environment to economic growth. This paper examines the determinants of light rail mode choice for medium/long distance trips (10-40km) for a new light rail system in Flanders, Belgium. To investigate these choices, the effects of various transport system specific factors (i.e. travel cost, in-vehicle travel time, transit punctuality, waiting time, access/egress time, transfers, and the availability of empty seats) as well as the travelers’ personal traits, are analyzed using an alternating logistic regression model, which explicitly takes into account the correlated responses for binary data. The data used for the analysis stem from a stated preference survey which was conducted in Flanders, Belgium. The modeling results yield findings that are in line with literature: most transport system specific factors as well as socio-economic variables, attitudinal factors, perceptions and the frequency of using public transport contribute significantly to the preference of light rail transit.

It also appeared that seat availability plays a more important role than transfers in the decision process to choose light rail transit.

The principal goal of this research is to model object’s evolution in space and time; it implies questioning identity, space and time. First, we define the concept of object spatio-temporal state. This concept allows modelling object identity evolution. Indeed, managing object identity must not be related to the object spatiality. In other words, we assume that the existence of an object is not dependant of its spatial extension. We show that there exist a lot of relationships associated to objects which does not yet exist or which does not exist anymore. We show also that when objects are not visible during an interval of time, it does not imply the lost of their identity. The model we propose aims at providing a framework for non-existent and non-visible objects Then, we study the spatio-temporal interactions between objects. The proposed solution is to define relationships between objects spatio-temporal states. It appears that the proposed set of relationships is a generalized vision of existing spatio-temporal reasoning models. Knowing that space-time continuity is not preserved in qualitative modelling, we apply the dominance theory which aims at retrieving continuous transitions between qualitative states. This development provides formal definitions of possible transition between spatio-temporal states relationships. Logically, the next step is to study the possible evolution of these spatio-temporal states relationships. This leads to the development of a formal model called “life and motion configurations”. This iconic representation gives a simplified view of the spatio-temporal evolution between two objects. It can be used to formalize the relationship between two spatio-temporal histories. In this work, we prove that this language is sufficient to provide spatio-temporal knowledge on moving objects. It determines also a framework in which others spatio-temporal reasoning models can be classified. Based on life and motion configurations, we propose two applications. Firstly, the life and motion configurations are generalised into a set of 25 relationships representing spatio-temporal information with a high level of abstraction. We believe that this set is close to people perception of spatio-temporal information. Secondly, two natural language interpretations of life and motion configurations are proposed; one applied to generalized spatio-temporal relationships, one applied to spatio-temporal predicates used in common French language.

En 1990 et en 1998, nous avons eu l’occasion de distribuer un questionnaire à plus de 800 étudiants de sept écoles secondaires de la région de Québec dans le but, entre autres, de déterminer certaines composantes de leurs sentiments d’appartenance. La comparaison de données, à une dizaine d’années d’intervalle, s’avère instructive, d’autant plus que nos résultats sont analysés à l’aide d’une méthode multidimensionnelle, la classification ascendante hiérarchique, qui nous permet de décomposer les images globales en une série de profils de réponses et de regrouper les individus interrogés en fonction des similitudes de ce profil. La pluralité des conceptions propres à chaque individu peut ainsi être mise en évidence dans nos échantillons, ce qui nous empêche de considérer la perception des différentes identités nationales comme une réalité homogène. On retiendra, entre autres, qu’en dix ans d’intervalle, la fierté d’être Québécois comme celle d’être Canadien a diminué de 20 % en comparant les échantillons globalement. Toutefois, l’enquête de 1998 nous montre également qu’au delà des options constitutionnelles préférées (63 % de l’échantillon privilégient d’abord l’indépendance ou la souveraineté-partenariat), le fait de considérer simultanément les indicateurs de fierté, de l’image des groupes linguistiques et de la hiérarchie des priorités offre un portrait beaucoup plus nuancé des positions des élèves de secondaire 4 et 5. À sa façon, les contradictions d’une société distincte s’y retrouvent toujours illustrées. [less ▲]
