Correlated correlation functions in random-bond ferromagnets

The two-dimensional random-bond Q-state Potts model is studied for Q near 2 via the perturbative renormalisation group to one loop. It is shown that weak disorder induces cross-correlations between the quenched-averages of moments of the two-point spin/spin and energy/energy correlation functions, which should be observable numerically in specific linear combinations of various quenched correlation functions. The random-bond Ising model in (2+epsilon) dimensions is similarly treated. As a byproduct, a simple method for deriving the scaling dimensions of all moments of the local energy operator is presented.Comment: AMS-LaTeX. 12 pages, 1 figur

(WP 2016-01) Transformation without Paternalism

Human development is meant to be transformational in that it aims to improve people’s lives by enhancing their capabilities. But who does it target: people as they are or the people they will become? This paper argues that the human development approach relies on an understanding of personal identity as dynamic rather than as static collections of preferences, and that this distinguishes human development from conventional approaches to development. Nevertheless this dynamic understanding of personal identity is presently poorly conceptualized and this has implications for development practice. We identify a danger of paternalism and propose institutionalizing two procedural principles as side constraints on development policies and projects: the principle of free prior informed consent, and the principle of democratic development

The Feral Cello: A Philosophically Informed Approach to an Actuated Instrument

There have been many NIME papers over the years on augmented or actuated instruments [2][10][19][22]. Many of these papers have focused on the technical description of how these instruments have been produced, or as in the case of Machover’s ‘Hyperinstruments’ [19], on producing instruments over which performers have ‘absolute control’ and emphasise ‘learnability. perfectibility and repeatability’ [19]. In contrast to this approach, this paper outlines a philosophical position concerning the relationship between instruments and performers in improvisational contexts that recognises the agency of the instrument within the performance process. It builds on a post-phenomenological understanding of the human/instrument relationship in which the human and the instrument are understood as co-defining entities without fixed boundaries; an approach that actively challenges notions of instrumental mastery and ‘absolute control’. This paper then takes a practice-based approach to outline how such philosophical concerns have fed into the design of an augmented actuated cello system, The Feral Cello, that has been designed to explicitly explore these concerns through practice

A General Expression for Hermite Expansions with Applications

Hermite polynomials arise when dealing with functions of normally distributed variables, and are commonly thought of as the analog of the simple polynomials on functions of regular variables. Therefore the Hermite expansion should be an analog of the Taylor expansion. Indeed there is a strong connection between the two – the general coefficient in the Hermite expansion is the weighted integral of the nth derivative, as compared to the nth derivative evaluated at zero in the case of Taylor. This fact can be used to derive the Hermite expansion for the integral and the derivative of a function. Furthermore, it provides a method of providing simple proofs of many of the Hermite identities. This connection is used to derive the Hermite expansions of the normal probability distribution function, the normal cumulative distribution function and the indicator function. Finally, an algorithm to numerically perform a Hermite expansion is presented, which is efficient in the sense that is only requires a single call to a quadrature method

Regulation of botulinum toxin complex formation in <i>Clostridium botulinum</i> type A NCTC 2916

Genomic DNA fragments encoding the silent type B neurotoxin gene from Clostridium botulinum NCTC 2916 have been cloned and the complete nucleotide sequence determined. The translated sequence revealed that the gene encoded a neurotoxin which was closely related to type B neurotoxin genes from Group I Clostridium botulinum. However among the nucleotide sequence differences, aG to T transition has interrupted the coding sequence with the formation of a stop codon. In addition the deletion of an adenine residue has resulted in a frame-shift mutation. Analysis of the DNA sequence contiguous with the silent type B neurotoxin gene revealed the presence of a gene encoding a Nontoxic-Nonhaemagglutinin protein which appears to share a bicistronic mRNA transcript with the type B neurotoxin gene. In the reverse orientation, the partial sequence of a gene encoding a haemagglutinin protein was found, typical of type A and B botulinal neurotoxin complexes. Separating the genes encoding the 'components of the neurotoxin complex was a gene of 178 amino acids which possessed features commonly associated with transcriptional factors. To facilitate the in vivo study of botulinal neurotoxin complex regulation, a gene transfer system using clostridial components has been developed. The minimal replicon of the cryptic plasmid pCB 102 from Clostridium butyricum NCIB 7423 was located to 1.6 kb DNA fragment by deletion analysis, enabling the identification of hitherto undiscovered putative ORFs and secondary structures, consistent with a replicative function. The replicon has been incorporated in to a number of Escherichia coli vectors resulting in a versatile series of shuttle vectors which have demonstrated high structural and segregational stabilities in a heterologous host Clostridium beyerinckii NCI NIB 8052. Gene transfer of a Group I Clostridium botulinum type A strain was demonstrated with a representative pCB 102-derived shuttle vector, pMTL540E. In addition, a 5.9 kb plasmid indigenous to C. botulimun NCTC 2916 was cloned and the complete nucleotide sequence determined. Eight putative ORFs have been identified, including a putative replication protein and recombinase
