The filmic fugue of Ken Russell’s Pop Goes the Easel

First broadcast as an episode of BBC Television’s Monitor in 1962, Ken Russell’s documentary film Pop Goes the Easel profiles four young artists: Pauline Boty, Peter Phillips, Derek Boshier and Peter Blake. With an exuberant and richly varied approach to filming, Pop Goes the Easel is a rich and revealing document of early Pop Art in London. This article situates the film within the context of television’s engagement with the visual arts in the medium’s first 25 years. It is argued that part of its significance within the tradition of the visual arts on television is its resistance to the determinations of an explanatory voice. Also, that its achievement combines and develops approaches of photojournalism, documentary and art cinema from the mid- and late 1950s. It is further proposed that Pop Goes the Easel is especially note-worthy for its finely-balanced tensions between discourses traditionally understood as oppositional: the stasis of artworks versus the linear narrative of film; the indexical qualities of documentary versus the inventions of fiction; the mass-produced elements and images of popular culture versus the individual authorship and authority of high art; the abstracted rationality of critical discourse versus explosions of embodied sensuality; and the determinations and closure of a singular meaning versus polysemous openness

Tidal interaction in binary black hole inspiral

In rotating viscous fluid stars, tidal torque leads to an exchange of spin and orbital angular momentum. The horizon of a black hole has an effective viscosity that is large compared to that of stellar fluids, and an effective tidal torque may lead to important effects in the strong field interaction at the endpoint of the inspiral of two rapidly rotating holes. In the most interesting case both holes are maximally rotating and all angular momenta (orbital and spins) are aligned. We point out here that in such a case (i) the transfer of angular momentum may have an important effect in modifying the gravitational wave ``chirp'' at the endpoint of inspiral. (ii) The tidal transfer of spin energy to orbital energy may increase the amount of energy being radiated. (iii) Tidal transfer in such systems may provide a mechanism for shedding excess angular momentum. We argue that numerical relativity, the only tool for determining the importance of tidal torque, should be more specifically focused on binary configurations with aligned, large, angular momenta.Comment: 5 pages, 2 figure

Enhancing 1α-Hydroxylase Activity with the 25-Hydroxyvitamin D-1α-Hydroxylase Gene in Cultured Human Keratinocytes and Mouse Skin

1α,25-Dihydroxyvitamin D3 (1α,25(OH)2D3) and its analogs are used to treat psoriasis because of their potent antiproliferative activity. They have the potential for causing hypercalcemia, however, and patients often become resistant to the drug. We examined the feasibility of enhancing the cutaneous production of 1α,25(OH)2D3 using a human 25-hydroxyvitamin D-1α-hydroxylase (1α-OHase) plasmid. The 1α-OHase gene was fused to the green fluorescent protein gene (1α-OHase-GFP) driven by the cytomegalovirus promoter. Transfection of cultured normal human keratinocytes with the 1α-OHase-GFP plasmid resulted in a marked increase in the expression of 1α-OHase-GFP in the mitochondria. Transfection of keratinocytes with 1α-OHase-GFP or 1α-OHase plasmids in vitro enhanced the 1α-OHase activity substantially and increased the sensitivity of the keratinocytes to the antiproliferative effect of 25(OH)D3. The 1α-OHase-GFP plasmid was topically applied to shaved C57/BL6 mice. Twenty-four hours after topical application, immunohistochemical analysis of the skin for 1α-OHase-GFP revealed the presence of 1α-OHase-GFP in the epidermis and epidermal appendages including the hair follicles. The results from this study offer a unique new approach for the topical treatment of hyperproliferative disorders such as psoriasis and skin cancer using the 1α-OHase gene that could locally increase the production of 1α,25(OH)2D3 without causing hypercalcemia or resistance

Binary-induced collapse of a compact, collisionless cluster

We improve and extend Shapiro's model of a relativistic, compact object which is stable in isolation but is driven dynamically unstable by the tidal field of a binary companion. Our compact object consists of a dense swarm of test particles moving in randomly-oriented, initially circular, relativistic orbits about a nonrotating black hole. The binary companion is a distant, slowly inspiraling point mass. The tidal field of the companion is treated as a small perturbation on the background Schwarzschild geometry near the hole; the resulting metric is determined by solving the perturbation equations of Regge and Wheeler and Zerilli in the quasi-static limit. The perturbed spacetime supports Bekenstein's conjecture that the horizon area of a near-equilibrium black hole is an adiabatic invariant. We follow the evolution of the system and confirm that gravitational collapse can be induced in a compact collisionless cluster by the tidal field of a binary companion.Comment: 9 Latex pages, 14 postscript figure
