A rhetoric of e|mediated (typo)graphicacy
This paper will discuss the distinctions between e|mediated and print (typo)graphic design by which its role might be reconsidered as significantly authorial, not merely formal or technical. Reproducing meaning on-screen alters conventions and assumptions which traditionally inform print-designers' attitudes to visual organisation. Not least amongst these is the increased visual significance of wayfinding requirements. Yet comfortable assumptions about (typo)graphic design as cultural producer must also change. As an ideological, elitist tool of consumerist persuasion it is not a rigorous discipline of public service. Yet ironically, not only does it exemplify the five arts of ancient rhetoric, the communicative action of the public sphere so central to democratic participation (supplanted by the rationalist abstractions of elitist philosophic discourses), but it also stands uniquely capable of addressing the paradoxical 'fissure' at the heart of contemporary rhetorical practice: the " division of the logos into form and content" (Hariman 227). Emedia enables virtually infinite and free publication, yet within technical constraints which engender possibilities for a radically analytic deconstruction of the conventional form of discursive codex-textuality. Through both static and dynamic juxtapositioning by which oscillation between formality and function may be visually instantiated it is possible to use (typo)graphic designing as a hermeneutic tool to make explicit the 'designing' consciousness behind all literacy, yet which is not normally explicit in writing. In a society saturated with remediation e|media may enable a radical, even humanistic rhetoric of (typo)graphicality.Hosted by the Scholarly Text and Imaging Service (SETIS), the University of Sydney Library, and the Research Institute for Humanities and Social Sciences (RIHSS), the University of Sydney

Tailored codes for small quantum memories
We demonstrate that small quantum memories, realized via quantum error
correction in multi-qubit devices, can benefit substantially by choosing a
quantum code that is tailored to the relevant error model of the system. For a
biased noise model, with independent bit and phase flips occurring at different
rates, we show that a single code greatly outperforms the well-studied Steane
code across the full range of parameters of the noise model, including for
unbiased noise. In fact, this tailored code performs almost optimally when
compared with 10,000 randomly selected stabilizer codes of comparable
experimental complexity. Tailored codes can even outperform the Steane code
with realistic experimental noise, and without any increase in the experimental
complexity, as we demonstrate by comparison in the observed error model in a
recent 7-qubit trapped ion experiment.Comment: 6 pages, 2 figures, supplementary material; v2 published versio
