Aurifeuillian factorization

The Cunningham project seeks to factor numbers of the form bn±1 with b = 2, 3, . . . small. One of the most useful techniques is Aurifeuillian Factorization whereby such a number is partially factored by replacing bn by a polynomial in such a way that polynomial factorization is possible. For example, by substituting y = 2k into the polynomial factorization (2y2)2+1 = (2y2−2y+1)(2y2+2y+1) we can partially factor 24k+2+1. In 1962 Schinzel gave a list of such identities that have proved useful in the Cunningham project; we believe that Schinzel identified all numbers that can be factored by such identities and we prove this if one accepts our definition of what “such an identity” is. We then develop our theme to similarly factor f(bn) for any given polynomial f, using deep results of Faltings from algebraic geometry and Fried from the classification of finite simple groups.

Characterisation of electrospun polystyrene scaffolds for three-dimensional in vitro biological studies

The purpose of this study was to produce a well-characterised electrospun polystyrene scaffold which could be used routinely for three-dimensional (3D) cell culture experimentation. A linear relationship (p<0.01p<0.01) between three principal process variables (applied voltage, working distance and polymer concentration) and fibre diameter was reliably established enabling a mathematical model to be developed to standardise the electrospinning process. Surface chemistry and bulk architecture were manipulated to increase wetting and handling characteristics, respectively. X-ray photoelectron spectroscopy (XPS) confirmed the presence of oxygen-containing groups after argon plasma treatment, resulting in a similar surface chemistry to treated tissue culture plastic. The bulk architecture of the scaffolds was characterised by scanning electron microscopy (SEM) to assess the alignment of both random and aligned electrospun fibres, which were calculated to be 0.15 and 0.66, respectively. This compared to 0.51 for collagen fibres associated with native tissue. Tensile strength and strain of approximately of 0.15 MPa and 2.5%, respectively, allowed the scaffolds to be routinely handled for tissue culture purposes. The efficiency of attachment of smooth muscle cells to electrospun scaffolds was assessed using a modified 3-[4,5-dimethyl(thiazol-2yl)-3,5-diphery] tetrazolium bromide assay and cell morphology was assessed by phalloidin-FITC staining of F-actin. Argon plasma treatment of electrospun polystyrene scaffold resulted in significantly increased cell attachment (p<0.05p<0.05). The alignment factors of the actin filaments were 0.19 and 0.74 for the random and aligned scaffold respectively, compared to 0.51 for the native tissue. The data suggests that electrospinning of polystyrene generates 3D scaffolds which complement polystyrene used in 2D cell culture systems.

'Producing the Scene': the Evolution of the Director in British Theatre 1900-50

The role of the director as the individual who harnesses and controls resources to shape the theatrical product to a personal artistic vision, begins to emerge in British theatre in the early years of the twentieth century. What distinguishes the role from that of the actor-manager who had led the profession since the seventeenth century, is that it separates off from the leading actor in performance. The power and authority of the director (or producer as he or she tended to be known initially) is exercised in the pre-performance stage. In the first half of the century there were still old-style actor-managers—Donald Wolfit is a prime example—and many of the new directors had begun their careers as actors and some continued to act their in their own productions. But the perception of the function of the director began to change radically. In part this was linked to the early attempts to create a new model of producing company or ‘repertory’ theatre which required a different set of administrative as well as artistic skills to tackle the challenge of a short-run system of multiple play production. This became especially important in the developing network of regional repertory theatres which were established as autonomous, locally-specific institutions predicated on policies opposed to the dominant commercial ethos. The best-known of the early directors, most notably H.Granville Barker, confined their radical experiments to short-lived metropolitan experiments, or, as in the case of Terence Gray and J.B.Fagan, operated within the influential Oxbridge nexus. Others such as H.K.Ayliff, Herbert Prentice, William Armstrong and William Bridges-Adams remain comparatively obscure because of their long-term ‘provincial’ connections or, as in the case of Nugent Monck and Edy Craig because their creativity was largely channelled through amateur actors. This chapter will explore the evolving role of the director as both a necessary functionary and an artistic innovator within the changing structures of British theatre.

BM: Tributación y concentración en el sistema financiero Colombiano 1989 - 2003

El presente documento analiza los determinantes del margen de intermediación para el sistema financiero colombiano entre 1989 y 2003. Bajo una estimación dinámica de los efectos generados por variables específicas de actividad, impuestos y estructura de mercado, se presenta un seguimiento del margen de intermediación financiero, para un período que presenta elementos de liberalización y crisis.
