Audiomobiles, Sculptures and Conundrums
No full textRoberto Gerhard was a pioneer of electronic music in England creating a number of substantial concert, theatre and radio works from as early as 1954. Gerhard’s electronic music is one of the richest repositories for understanding the development of the composer’s late compositional technique. Apart from the Symphony no.3, ‘Collages’, none of Gerhard’s electronic music is published. This paper will discuss aspects of Gerhard’s electronic music, focusing on Audiomobiles (1958-59) and Sculptures (1963)
Coarse-grained models for polymer solutions and colloid-polymer mixtures
No full textCoarse-grained models are a very powerful ---and sometimes necessary--- tool in the analysis of the thermodynamic properties of macromolecular fluids. In these models, most of the original, microscopic degrees of freedom are integrated out and each macromolecule is mapped onto a set of effective sites, mutually interacting by means of appropriate intermolecular and intramolecular potentials. Depending on the number of sites n chosen, each macromolecule can be represented as a soft monoatomic molecule (n=1), or as a soft n-atomic molecule (n>1). The complexity of determining the complete set of effective interactions among the coarse-grained sites is such that an exact mapping is unfeasible in practice, hence approximations must be introduced, which always generate a lack of consistency between the original and the coarse-grained model.
In this thesis, we apply coarse-graining strategies to the investigation of the universal, large scale and thermodynamic properties of polymer solutions and colloid-polymer mixtures, for two different polymer architectures: linear chains and star polymers. We begin the discussion by briefly summarizing the main concepts of statistical mechanics and polymer physics, in a general fashion. We then revise the formalism behind structure-based coarse-graining procedures, both single-site and multi-site, critically analyzing their limits of validity and the methods proposed in the literature to extend them. Thereafter, we determine the accuracy of coarse-grained, single-site mappings in reproducing the correct thermodynamic behavior of solutions of linear chains and colloid-linear chain mixtures, for different average polymer-to-colloid size ratios. In conclusion, we discuss coarse-grained models for star polymer solutions in good solvents. We introduce a new multi-site model for star polymers, whose validity should extend up to the semidilute regime, and compare its predictions for the thermodynamic properties of the system with those obtained by means of single-site models
Comparing different coarse-grained potentials for star polymers
No full textWe compare different coarse-grained single-blob models for star polymers. We find that phenomenological models inspired by the Daoud-Cotton theory reproduce quite poorly the thermodynamics of these systems, even if the potential is assumed to be density dependent, as done in the analysis of experimental results. Using the numerically determined coarse-grained potential, we also determine the minimum value f(c) of the functionality of the star polymer for which a fluid-solid transition occurs. By applying the Hansen-Verlet criterion we find 35 < f(c) less than or similar to 40. This result is confirmed by an analysis that uses the modified (reference) hypernetted chain method and is qualitatively consistent with previous work. (C) 2013 American Institute of Physics.

Roberto Gerhard’s Sound Compositions: A Historical-Philological Perspective. Archive, Process, Intent and reenactment
No full textThis research advances the current state of knowledge in the field of early tape music both empirically and methodologically. The purpose of this study is to evaluate the impact that the electronic medium exerted in the musical thinking of Roberto Gerhard, one of the most outspoken, prolific and influential composers in the Spanish diaspora whose musical legacy, for the most part unknown, is a major landmark in the early history of electroacoustic music. Gerhard’s personal tape collection, one of the largest historical archives of its kind reported in the literature, is exceptional for both its antiquity (50+-year-old tapes) and its abundance of production materials. Through the digitisation and analysis of the composer’s tape collection this research argues that the empirical study of audio documents sets out a basis for a broader understanding of textual processes. More specifically, the research demonstrates that the reconstruction of works based on magnetic tape sketches is a powerful method to advance the understanding of early tape music. This research also examines Gerhard’s sound compositions in relation to the post-war context in which they were composed. Finally, this research presents performance documentation that proposes an approach to the electroacoustic music repertoire in which creativity is not at odds with rigor and critical discernment demonstrating that archival study can be closely aligned to the concept of re-enactment
Integral equation analysis of single-site coarse-grained models for polymer-colloid mixtures
No full textWe discuss the reliability of integral equation methods based on several commonly used closure relations in determining the
phase diagram of coarse-grained models of soft-matter systems characterised by mutually interacting soft- and hard-core
particles. Specifically, we consider a set of potentials appropriate to describe a system of hard-sphere colloids and linear
homopolymers in good solvent, and investigate the behaviour when the soft particles are smaller than the colloids, which
is the regime of validity of the coarse-grained models. Using computer-simulation results as a benchmark, we find that the
hypernetted-chain approximation provides accurate estimates of thermodynamics and structure in the colloid–gas phase in
which the density of colloids is small. On the other hand, all closures considered appear to be unable to describe the behaviour
of the mixture in the colloid–liquid phase, as they cease to converge at polymer densities significantly smaller than those at
the binodal. As a consequence, integral equations appear to be unable to predict a quantitatively correct phase diagram
Thermodynamics of star polymer solutions: A coarse-grained study
No full textWe consider a coarse-grained (CG) model with pairwise interactions, suitable to describe low-density solutions of star-branched polymers of functionality f. Each macromolecule is represented by a CG molecule with (f + 1) interaction sites, which captures the star topology. Potentials are obtained by requiring the CG model to reproduce a set of distribution functions computed in the microscopic model in the zero-density limit. Explicit results are given for f = 6, 12, and 40. We use the CG model to compute the osmotic equation of state of the solution for concentrations c such that Φp = c/c∗ = 1, where c∗ is the overlap concentration. We also investigate in detail the phase diagram for f = 40, identifying the boundaries of the solid intermediate phase. Finally, we investigate how the polymer size changes with c. For Φp less than 0.3, polymers become harder as f increases at fixed reduced concentration c/c∗. On the other hand, for Φp larger than 0.3, polymers show the opposite behavior:At fixed Φp, the larger the value of f, the larger their size reduction is

Roberto Bolaño, la memoria antiheroica del exilio chileno
No full textThis article discusses the personality and the work of the Chilean writer Roberto Bolaño in an attempt to expand on the relationship between the author and his homeland Chile. Even though Bolaño left Chile at an early age and lived in many countries throughout his life, he tried to regain his roots as reflected in the novels about the Chilean dictatorship, Estrella distante and Nocturno de Chile. The author also attempts to vindicate his own origin in his literary alterego Arturo Belano. Thus, this article will highlight and analyse the relation between Roberto Bolaño and Chile through the antiheroic vision given not only to the characters but also to the settings of the narratives.Este artículo se centra en la personalidad del escritor chileno Roberto Bolaño y su obra para profundizar en la relación existente entre el autor y Chile, su país de origen. Pese a haber abandonado el país siendo muy joven y a haber residido en otros países a lo largo de su vida, Bolaño nunca perdió el interés por recuperar sus raíces chilenas tanto como lo reflejan las novelas que dedica a la dictadura chilena, Estrella distante y Nocturno de Chile sobre todo, así como por reivindicar su propio origen a través de su álter ego literario Arturo Belano. En este artículo se señalarán y analizarán estas relaciones entre Roberto Bolaño y Chile a través de la visión antiheroica que el autor confiere tanto a los ambientes como a los personajes que articulan su narrativa
