Introduction: Legal Form and Cultural Symbol – Music, Copyright and Information Studies

Writers in information and communication studies often assume the stability of objects under investigation: network nodes, databases, information. Legal writers in the intellectual property tradition often assume that cultural artefacts exist as objects prior to being governed by copyright law. Both assumptions are fallacious. This introduction conceptualises the relationship of legal form and cultural symbol. Starting from an understanding of copyright law as part of systems of production (in the sense of Peterson 1976), it is argued that copyright law constructs the artefacts it seeks to regulate as objects that can be bought and sold. In doing so, the legal and aesthetic logic of cultural symbols may clash, as in the case of digital music (the central focus of this special issue)

Transgressive bodies in the work of Julie Doucet, Fabrice Neaud and Jean-Christophe Menu: towards a theory of the 'autobioBD'

As the comic book, and more precisely its exceptionally francophone doppelganger, la bande dessinée, begins to fulfil its potential as 'the Ninth Art', the range of styles, reading contexts, and genres which constitute the form as a signifying practice has consequently expanded. Consideration of 'what a comic is', such as is found in the works of Thierry Groensteen and Benoît Peeters1 needs therefore to be complemented by a range of subsidiary questions addressing not only 'what kinds of comics there are', but, as an integral part of those inquiries, how different comic genres signify, and how the enunciative and representational functions deployed by each might be conceptualised. This paper considers the work of three Francophone comic artists, Fabrice Neaud and Jean-Christophe Menu, both French, and the Québecoise Julie Doucet, all of whom could be considered as proponents of the genre of BD we will call 'autobiocomics'. It will be argued that Neaud and Doucet, through their exploration of ontologies of presence and self-representation, work against the visual order of the phallocentric and heteronormative, an order which Menu appears to replicate but ultimately calls into question

The thalamic reticular nucleus: a functional hub for thalamocortical network dysfunction in schizophrenia and a target for drug discovery

The thalamus (comprising many distinct nuclei) plays a key role in facilitating sensory discrimination and cognitive processes through connections with the cortex. Impaired thalamocortical processing has long been considered to be involved in schizophrenia. In this review we focus on the thalamic reticular nucleus (TRN) providing evidence for it being an important communication hub between the thalamus and cortex and how it may play a key role in the pathophysiology of schizophrenia. We first highlight the functional neuroanatomy, neurotransmitter localisation and physiology of the TRN. We then present evidence of the physiological roles of the TRN in relation to oscillatory activity, cognition and behaviour. Next we discuss the role of the TRN in rodent models of risk factors for schizophrenia (genetic and pharmacological) and provide evidence for TRN deficits in schizophrenia. Finally we discuss new drug targets for schizophrenia in relation to restoring TRN circuitry dysfunction

Implications of the unusual structure in the pp correlation from Pb+Pb collisions at 158 AGeV

The recent NA49 measurement of two-proton correlation function shows an interesting and unexpected structure at large relative momentum. Applying source imaging techniques to the measurement, we find an unusually steep drop-off in the two-proton source function. We show that the steep drop-off is due to the structure in the correlation and the drop-off cannot be explained using conventional correlation analysis. We suggest possible physics reasons for the unusual source function.Comment: 6 pages, 3 eps figures, uses RevTex.sty. To appear in Physics Letters B.

Fluctuation dynamo amplified by intermittent shear bursts in convectively driven magnetohydrodynamic turbulence

Intermittent large-scale high-shear flows are found to occur frequently and spontaneously in direct numerical simulations of statistically stationary turbulent Boussinesq magnetohydrodynamic (MHD) convection. The energetic steady-state of the system is sustained by convective driving of the velocity field and small-scale dynamo action. The intermittent emergence of flow structures with strong velocity and magnetic shearing generates magnetic energy at an elevated rate over time-scales longer than the characteristic time of the large-scale convective motion. The resilience of magnetic energy amplification suggests that intermittent shear-bursts are a significant driver of dynamo action in turbulent magnetoconvection

Physical meaning of two-particle HBT measurements in case of correlated emission

It is shown that, in the presence of correlations in particle emission, the measured HBT radii are related to the correlation range rather than to the size of the interaction volume. Only in the case of weak correlations the standard interpretation may be applicable, The earlier discussion [1] of short-range correlations in configuration space is generalized to include also the correlations of particle momenta.Comment: 12 pages, no figure

Integral lift engine preliminary design

A preliminary mechanical design of a complete lift fan engine system is reported. A description of the lift fan engine, layout drawings of the components and complete engine, and a discussion of the design analyses and results are presented. The design features and areas of analysis include fan and compressor rotor blades of composite construction, a combustor folded over the compressor, relatively high-temperature blades in the high-pressure turbine, the first stage of the low-pressure turbine used for bearing support and ducting of lubricant to the bearings, a complete lubrication system, critical speeds of the shafting, and vibration and flutter of the blading
