In this article, we consider the wave equation in a bounded domain Ω of R with a potential q. Our goal then is to show that the high-frequency part of the corresponding solutions weakly depends on the potential. We will in particular focus on two instances of interest arising in data assimilation and control theory, respectively corresponding to the problem of recovering an initial data from a ...

Recently, Constant, Gataullina, and Zimmermann (2009) established a new method to measure ethnic identity which they called the "ethnosizer". Using information on an individual's language, culture, social interactions, history of migration, and ethnic selfidentification, the method classifies that individual into one of four states: assimilation, integration, separation or marginalization. A la...

There has been increased attention to urban form in the recent segregation literature, showing population density and changes in housing structure as having crucial influence on segregation patterns (Spielman and Harrison 2013; Rothwell and Massey 2010; Watson 2006). However, there has been little work examining areas with newly constructed housing, looking at what kinds of people move to these...

There has been a large quantity of research that has been carried out on interorganizational systems in recent years. Because research in this area has been carried out for a long time, it is becoming increasingly difficult to find new aspects of it to explore. The aim of this study is to identify the published literature on IOS from 2006 to 2015, review them, and apply a suitable framework to ...

The evolution of a population can be guided by phenotypic traits acquired by members of that population during their lifetime. This phenomenon, known as the Baldwin EEect, can speed the evolutionary process as traits that are initially acquired become genetically speciied in later generations. This paper presents conditions under which this genetic assimilation can take place. As well as the be...

Color Assimilation is a very obvious effect, in which two identical stimuli appear very different hues. This paper studies the hypothesis that the broad spectral sensitivity functions of human vision are the cause of these spatial effects. The results show that the long-wave response to middle-wave light, and the middle-wave response to longwave light introduce spatial effects consistent with o...

We present a Lagrangian data assimilation experiment in an open channel flow above a broad-crested weir. The observations consist of trajectories of particles transported by the flow and extracted from a video film, in addition to classical water level measurements. However, the presence of vertical recirculations on both sides of the weir actually conducts to the identification of an equivalen...
