The combination of local orientation collinearity and spatial frequency contrast in contour integration was studied in two experiments using a 2AFC contour detection and discrimination task. Target contours were defined by local orientation collinearity, spatial frequency contrast between contour and background elements, or both cues. Experiments differed in the source of spatial frequency contrast by manipulating the spatial frequency of either contour or background elements. Cue summation gains, defined as the performance benefit of double cue conditions over single cue conditions, were evaluated and tested against the predictions derived from probability summation and linear summation.

A cross-cultural study using Napping (R): Do Korean and French consumers perceive various green tea products differently?
2013
http://www.elsevier.com/locate/foodres ; WOS:000323239400065; International audience; With the increasing demands of global trading, interests in cross-cultural comparisons have increased to gain understanding in the differences of sensory perception and consumer acceptability. The objective of this study was to compare the differences in perception by Korean and French consumers of green tea produced in Korea, China, and Japan, using Napping (R) followed by ultra flash profile. In addition, overall acceptability was examined in both countries. The results of Napping (R) showed that the Korean consumers were able to discriminate the green teas according to their origins and processing metho…
Acoustic detection of neutrinos in bedrock
2019
We propose to utilize bedrock as a medium for acoustic detection of particle showers following interactions of ultra-high energy neutrinos. With the density of rock three-times larger and the speed of sound four-times larger compared to water, the amplitude of the generated bipolar pressure pulse in rock should be larger by an order of magnitude. Our preliminary simulations confirm that prediction. Higher density of rock also guarantees higher interaction rate for neutrinos. A noticeably longer attenuation length in rock reduces signal dissipation. The Pyh\"asalmi mine has a unique infrastructure and rock conditions to test this idea and, if successful, extend it to a full-size experiment.
A boundary condition for arbitrary shaped inlets in lattice-Boltzmann simulations
2009
We introduce a mass-flux-based inlet boundary condition for the lattice-Boltzmann method. The proposed boundary condition requires minimal amount of boundary data, it produces a steady-state velocity field which is accurate close to the inlet even for arbitrary inlet geometries, and yet it is simple to implement. We demonstrate its capability for both simple and complex inlet geometries by numerical experiments. For simple inlet geometries, we show that the boundary condition provides very accurate inlet velocities when Re less than or similar to 1. Even with moderate Reynolds number, the inlet velocities are accurate for practical purposes. Furthermore, the potential of our boundary condit…
Fostering sustained teacher learning: a longitudinal assessment of the influence of vision building and goal interdependence on information sharing
2020
To support school improvement, understanding the mechanisms that enhance teachers’ engagement in professional learning activities within schools over time is paramount. The purpose of this three-wave longitudinal study is to examine the role of workplace conditions (school leaders’ vision building and teams’ shared goals), in supporting teachers’ engagement in information sharing over time. To test the directionality of the relationships between the concepts, we analyzed survey data from 655 vocational education and training teachers in the Netherlands using a cross-lagged panel model. Results suggest that teachers’ engagement in information sharing remains stable over time, and the results…
L'évaluation socio-économique des infrastructures de transport : enrichir les approches du développement territorial
2007
International audience; Dans les années récentes, en France, le processus décisionnel en matière de grands équipements a sensiblement évolué, débouchant sur des réponses institutionnelles en termes de procédures adaptées. Ceci a eu pour conséquence d'accroître l'exigence informationnelle destinée à alimenter les débats, éclairer les problématiques abordées, leur donner un contenu le plus objectivé possible. L'une des principales thématiques systématiquement abordées dans le cadre de ces procédures participatives, est celle du développement territorial, dont l'importance en fait un des éléments essentiels de l'acceptabilité sociale. Les enseignements des observatoires socio-économiques autor…
The migration–tourism nexus in the EU28
2020
This study explores the nexus between tourism and migration on an intra-European scale over the period 2000–2015. Complex-network analysis and gravity models were the investigation methods preferred. For each year under study, we built two country-to-country networks to map and reveal the connections between states as shaped by migration stocks and tourism flows, respectively. Then, the main determinants of the correlation patterns between the two networks were investigated by several econometric analysis. Results point to a quite similar topological structure for the tourism and migration networks as well as to a significant and reciprocal direct influence between tourism and migration mo…
Interaction of hadrons and tests for the nature of resonances
2016
El propósito de esta Tesis es contribuir al extenso esfuerzo que se ha hecho, en las ultimas décadas, a fin de entender la estructura de las partículas hadrónicas, uno de los temas más importantes en física hadrónica. En los años 50, el desarrollo de los aceleradores de partículas reveló la existencia de una gran cantidad de nuevas resonancias. La proliferación de partículas, poco después, manifestó un patrón, y un esquema de organización para describirlo se hizo necesario. Al principio, se encontró una solución generalizando el concepto de isospín con el modelo de Fermi-Yang de 1959, en el que el protón y el neutrón aparecen como bloques fundamentales y las otras partículas como sus combin…
Managing complexity in global IT projects
2017
Projektien hallintaan kuuluu paljon erilaisia osa-alueita, joita projektipäällikön ja korkeamman tason henkilöstön tulee ottaa huomioon ennen projektin alkua ja sen aikana. Projektin kompleksisuus nousee kuitenkin erittäin korkealle ta-solle, kun kyseessä on kansainvälinen IT-projekti. Tämän kaltaisissa projek-teissa on useita osa-alueita, jotka voivat vaikuttaa kriittisesti niiden onnistumi-seen. Tämä tutkimus keskittyy havainnoimaan, mistä asioista kompleksisuus koostuu globaalien IT-projektien tapauksessa, miten se linkittyy kompleksi-suusteoriaan ja miten tätä kompleksisuutta kyetään hallitsemaan. Tekotapana tässä tutkimuksessa on kirjallisuuskatsaus. Kirjallisuus on kerätty kirjastoist…
Review of Particle Physics
2020
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,143 new measurements from 709 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. Particle properties and search limits are listed in Summary Tables. We give numerous tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, …
