New Results in Light-Front Phenomenology

The light-front quantization of gauge theories such as QCD in light-cone gauge provides a frame-independent wavefunction representation of relativistic bound states, simple forms for current matrix elements, explicit unitarity, and a trivial vacuum. The freedom to choose the light-like quantization four-vector provides an explicitly covariant formulation of light-front quantization and can be used to determine the analytic structure of light-front wave functions and to define a kinematical definition of angular momentum. The AdS/CFT correspondence of large $N_C$ supergravity theory in higher-dimensional anti-de Sitter space with supersymmetric QCD in 4-dimensional space-time has interesting implications for hadron phenomenology in the conformal limit, including an all-orders demonstration of counting rules for exclusive processes. String/gauge duality also predicts the QCD power-law behavior of light-front Fock-state hadronic wavefunctions with arbitrary orbital angular momentum at high momentum transfer. The form of these near-conformal wavefunctions can be used as an initial ansatz for a variational treatment of the light-front QCD Hamiltonian. I also briefly review recent analyses which shows that some leading-twist phenomena such as the diffractive component of deep inelastic scattering, single-spin asymmetries, nuclear shadowing and antishadowing cannot be computed from the LFWFs of hadrons in isolation.Comment: Presented at LightCone 2004, Amsterdam, The Netherlands, 16-20 August 200

The maximum of Brownian motion minus a parabola

We derive a simple integral representation for the distribution of the maximum of Brownian motion minus a parabola, which can be used for computing the density and moments of the distribution, both for one-sided and two-sided Brownian motion.Comment: 7 pages, 4 figures, to appear in the Electronic Journal of Probabilit

Rethinking the Social Construction of Technology Through 'Following the Actors': A Reappraisal of Technological Frames

In this paper, I summarize case study research on an information system called Connected Kids. This case study was guided by an approach to technology studies called the \'Social construction of technology\' or SCOT Bijker (1984). In discussing Connected Kids, I illustrate many of SCOT\'s main tenents, e.g. the various social interactions that surround and influence technology design. As the paper progresses, however, I focus on one concept in particular, i.e. SCOT\'s notion of a \'technological frame,\' which is used as a catch-all concept for handling the structural influences in technology design. My discussion and illustration of this concept shows that – whilst technological frames help an analyst understand, in general terms, the role structure(s) play in shaping technology – the \'heterogeneity\' of technological frames can cloak the more obvious, and potentially most influential, forces at work in technology design. In the case of Connected kids, the role of resources, and which actors had access to these resources, was critical in pointing Connected Kids down a particular trajectory. Further, this discovery emerged from listening carefully to respondents\' comments on the role of resources in their community. These comments, and my own observations on how resource-access propelled certain actors into a leadership position, led to my developing an alternative method for analyzing technological frames. The implications of this analysis are then discussed within the context of SCOT and technology studies more generally.Social Construction of Technology, Technological Frames, Information Technology

Development of the Resource Module for the European Space Station Programme Columbus

This presentation summarizes the module during the study phases B1 May 1987. evolution of a resource and B2 from July 1985 to May The development has been performed by Dornier System on behalf of the European Space Agency ESA leading a consortium of 12 European companies. This summary shows the aim of establishing a design concept supposed to be most flexible with respeqt to changing mission scenarios as wel~ ~s different applications of the module. The presentation also shows the development of the design itself with emphasis on the present reference configuration. 1987
