Collecting Places

Memory Flows, a project of the Centre for Media Arts and Innovation, UTS, culminated in an exhibition entitled 'Memory Flows: rivers, creeks and the great artesian basin' which examined the concepts of 'water, flows and memory'. Curated by Sophia Kouyoumdjian, Norie Neumark and Deb Turnbull, it featured fifteen media artworks by twenty CMAI members and affiliated artists: Ian Andrews, Chris Bowman, Chris Caines, Damian Castaldi, Sherre DeLys, Clement Girault, Jacqueline Gothe, Ian Gwilt, Nigel Helyer, Megan Heyward, Neil Jenkins, Solange Kershaw, Roger Mills, Maria Miranda, Norie Neumark, Shannon O'Neill, Greg Shapley, Victor Steffensen, Jen Teo and Jes Tyrrell. The exhibition, open for 15 days over two months with a public forum on June 20, included video and audio installations, interactive media works, mobile devices, projections on surfaces and through water, and an array of river related artworks and artefacts. Audience numbers totalled 2,700 visitors. 'Collecting Places' is the outcome of a collaboration between Jacqueline Gothe and Shere Delys from ABC Radio and Executive Producer of POOL, http://pool.abc.net.au/. The installation is a chalk drawing on a brick wall with a sound scape. The image resulted from Gothe drawing in the studio as DeLys meditated at the Coorong in South Australia, the place where the Murray River meets the ocean. The outcome of the collaborative process contributes to Gothe's participatory practice, Drawing Country, an ongoing research project that advocates an examination of the ways to enhance connectedness and connection to place through visual communication. Memory Flows 2009-2010, a distributed media art project of the CMAI, was funded by the Inter-Arts Board of the Australia Council for the Arts

Hard Exclusive Pion Electroproduction at Backward Angles With CLAS

We report on the first measurement of cross sections for exclusive deeply virtual pion electroproduction off the proton, ep → e\u27nπ+, above the resonance region at backward pion center-of-mass angles. The ϕ∗ π-dependent cross sections were measured, from which we extracted three combinations of structure functions of the proton. Our results are compatible with calculations based on nucleon-to-pion transition distribution amplitudes (TDAs). These non-perturbative objects are defined as matrix elements of threequark-light-cone-operators and characterize partonic correlations with a particular emphasis on baryon charge distribution inside a nucleon

Measurements of the Gamma(Upsilon)p -\u3e p ’pi(+)Pi(- )Cross Section with the CLAS Detector for 0.4 GeV2 \u3c Q(2) \u3c 1.0 GeV2 and 1.3 GeV \u3c W \u3c 1.825 GeV

New results on the single-differential and fully integrated cross sections for the process γvp -\u3e p\u27π+π- are presented. The experimental data were collected with the CLAS detector at Jefferson Laboratory. Measurements were carried out in the kinematic region of the reaction invariant mass W from 1.3 to 1.825 GeV and the photon virtuality Q2 from 0.4 to 1.0 GeV2. The cross sections were obtained in narrow Q2 bins (0.05 GeV2) with the smallest statistical uncertainties achieved in double-pion electroproduction experiments to date. The results were found to be in agreement with previously available data where they overlap. A preliminary interpretation of the extracted cross sections, which was based on a phenomenological meson-baryon reaction model, revealed substantial relative contributions from nucleon resonances. The data offer promising prospects to improve knowledge on the Q2 evolution of the electrocouplings of most resonances with masses up to similar to ~ 1.8 GeV
