The ATLAS Experiment at the CERN Large Hadron Collider

Abstract: The ATLAS detector as installed in its experimental cavern at point 1 at CERN is described in this paper. A brief overview of the expected performance of the detector when the Large Hadron Collider begins operation is also presented.

Locating the nodes: cooperative localization in wireless sensor networks

Abstract: Accurate and low-cost sensor localization is a critical requirement for the deployment of wireless sensor networks in a wide variety of applications. In cooperative localization, sensors work together in a peer-to-peer manner to make measurements and then forms a map of the network. Various application requirements influence the design of sensor localization systems. In this article, the authors describe the measurement-based statistical models useful to describe time-of-arrival (TOA), angle-of-arrival (AOA), and received-signal-strength (RSS) measurements in wireless sensor networks. Wideband and ultra-wideband (UWB) measurements, and RF and acoustic media are also discussed. Using the models, the authors have shown the calculation of a Cramer-Rao bound (CRB) on the location estimation precision possible for a given set of measurements. The article briefly surveys a large and growing body of sensor localization algorithms. This article is intended to emphasize the basic statistical signal processing background necessary to understand the state-of-the-art and to make progress in the new and largely open areas of sensor network localization research.

Who is this "We"? Levels of collective identity and self representations.

Abstract: Cross-cultural perspectives have brought renewed interest in the social aspects of the self and the extent to which individuals define themselves in terms of their relationships to others and to social groups. This article provides a conceptual review of research and theory of the social self, arguing that the personal, relational, and collective levels of self-definition represent distinct forms of selfrepresentation with different origins, sources of self-worth, and social motivations. A set of 3 experiments illustrates haw priming of the interpersonal or collective "we" can alter spontaneous judgments of similarity and self-descriptions. Until recently, social psychological theories of the self focused on the individuated self-concept—the person's sense of unique identity differentiated from others. Cross-cultural perspectives, however, have brought a renewed interest in the social aspects of the self and the extent to which individuals define themselves in terms of their relationships to others and to social groups (Markus & Kitayama, 1991; Triandis, Bontempo, Villareal, Asai, & Lucca, 1988). Central to this new perspective is the idea that connectedness and belonging are not merely affiliations or alliances between the self and others but entail fundamental differences in the way the self is construed (Brewer, 1991; Markus & Kitayama, 1991; Singelis, 1994; Trafimow, Triandis, & Goto, 1991; Triandis, 1989; Turner, Oakes, Haslam, & McGarty, 1994). Some of these theories of the social self focus on cross-cultural differences in whether the self is typically construed as individuated or interpersonal. However, all recognize that these different self-construals may also coexist within the same individual, available to be activated at different times or in different contexts. Furthermore, in several theories, achieving an extended sense of self has the status of a fundamental human motivation (Baumeister & Leary, 1995; Brewer, 1991). In other words, individuals seek to define themselves in terms of their immersion in relationships with others and with larger collectives and derive much of their self-evaluation from such social identities (Breckler & Greenwald, 1986; Greenwald & Breckler, 1985). The motivational properties of collective identities are systematically documented in Baumeister and Leary's (1995) comprehensive review of the evidence in support of a fundamental "need to belong" as an innate feature of human nature. All of the theories mentioned above draw some kind of distinction between the individuated or personal self (those aspects of the self-concept that differentiate the self from all others) and a relational or social self (those aspects of the self-concept that
