Kia ora and welcome to the second issue of BackStory. The members of the Backstory Editorial Team were gratified by the encouraging response to the first issue of the journal. We hope that our currentreaders enjoy our new issue and that it will bring others to share our interest in and enjoyment of the surprisingly varied backstories of New Zealand’s art, media, and design history. This issue takes in a wide variety of topics. Imogen Van Pierce explores the controversy around the Hundertwasser Art Centre and Wairau Māori Art Gallery to be developed in Whangarei. This project has generated debate about the role of the arts and civic architecture at both the local and national levels. This is about how much New Zealanders are prepared to invest in the arts. The value of the artist in New Zealand is also examined by Mark Stocker in his article about the sculptor Margaret Butler and the local reception of her work during the late 1930s. The cultural cringe has a long genealogy. New Zealand has been photographed since the 1840s. Alan Cocker analyses the many roles that photography played in the development of local tourism during the nineteenth century. These images challenged notions of the ‘real’ and the ‘artificial’ and how new technologies mediated the world of lived experience. Recorded sound was another such technology that changed how humans experienced the world. The rise of recorded sound from the 1890s affected lives in many ways and Lewis Tennant’s contribution captures a significant tipping point in this medium’s history in New Zealand as the transition from analogue to digital sound transformed social, commercial and acoustic worlds. The New Zealand Woman’s Weekly celebrates its 85th anniversary this year but when it was launched in 1932 it seemed tohave very little chance of success. Its rival, the Mirror, had dominated the local market since its launch in 1922. Gavin Ellis investigates the Depression-era context of the Woman’s Weekly and how its founders identified a gap in the market that the Mirror was failing to fill. The work of the photographer Marti Friedlander (1908-2016) is familiar to most New Zealanders. Friedlander’s 50 year career and huge range of subjects defy easy summary. She captured New Zealanders, their lives, and their surroundings across all social and cultural borders. In the journal’s profile commentary Linda Yang celebrates Freidlander’s remarkable life and work. Linda also discusses some recent images by Friedlander and connects these with themes present in the photographer’s work from the 1960s and 1970s. The Backstory editors hope that our readers enjoy this stimulating and varied collection of work that illuminate some not so well known aspects of New Zealand’s art, media, and design history. There are many such stories yet to be told and we look forward to bringing them to you.

The Difference

Der deutsche Barockdichter Georg Philipp Harsdörffer skizziert eine Theorie der Emblematik, die vor allem dessen Anwendungsvielfalt hervorhebt. Er hebt dabei besonders den Unterschied zwischen buchinterner und buchexterner Verwendung auf, indem er sich nicht nur für die Aufnahme der Embleme in Büchern, sondern auch auf Geschirr und Tapeten ausspricht. Der Beitrag liest Harsdörffers extensive Überlegungen nicht nur als Beiträge zur Theorie und Geschichte der Embleme als ›Sinn-Bilder‹, sondern auch als Beitrag zur Designgeschichte. German Baroque poet Georg Philipp Harsdörffer delineates a theory of emblematics that clearly sets itself apart from other contemporary theories, especially by its versatility. In particular, the author negates the difference between internal and external usage of emblems in books not only by promoting the incorporation of emblems into printed works but also by supporting their depiction on dishes and tapestries. This article strives to read Harsdörffer’s extensive thoughts on the matter of emblems not simply as another work on the theory and history of emblematics but rather as a contribution to design history as well

AbstractPrecision medicine is a new frontier in healthcare that uses scientific methods to customize medical treatment to the individual genes, anatomy, physiology, and lifestyle of each person. In cardiovascular health, precision medicine has emerged as a promising paradigm to enable cost-effective solutions that improve quality of life and reduce mortality rates. However, the exact role in precision medicine for human heart modeling has not yet been fully explored. Here, we discuss the challenges and opportunities for personalized human heart simulations, from diagnosis to device design, treatment planning, and prognosis. With a view toward personalization, we map out the history of anatomic, physical, and constitutive human heart models throughout the past three decades. We illustrate recent human heart modeling in electrophysiology, cardiac mechanics, and fluid dynamics and highlight clinically relevant applications of these models for drug development, pacing lead failure, heart failure, ventricular assist devices, edge-to-edge repair, and annuloplasty. With a view toward translational medicine, we provide a clinical perspective on virtual imaging trials and a regulatory perspective on medical device innovation. We show that precision medicine in human heart modeling does not necessarily require a fully personalized, high-resolution whole heart model with an entire personalized medical history. Instead, we advocate for creating personalized models out of population-based libraries with geometric, biological, physical, and clinical information by morphing between clinical data and medical histories from cohorts of patients using machine learning. We anticipate that this perspective will shape the path toward introducing human heart simulations into precision medicine with the ultimate goals to facilitate clinical decision making, guide treatment planning, and accelerate device design.

The Impact

AbstractRecent studies on neural network quantization have demonstrated a beneficial compromise between accuracy, computation rate, and architecture size. Implementing a 3D Vertical RRAM (VRRAM) array accompanied by device scaling may further improve such networks’ density and energy consumption. Individual device design, optimized interconnects, and careful material selection are key factors determining the overall computation performance. In this work, the impact of replacing conventional devices with microfabricated, graphene-based VRRAM is investigated for circuit and algorithmic levels. By exploiting a sub-nm thin 2D material, the VRRAM array demonstrates an improved read/write margins and read inaccuracy level for the weighted-sum procedure. Moreover, energy consumption is significantly reduced in array programming operations. Finally, an XNOR logic-inspired architecture designed to integrate 1-bit ternary precision synaptic weights into graphene-based VRRAM is introduced. Simulations on VRRAM with metal and graphene word-planes demonstrate 83.5 and 94.1% recognition accuracy, respectively, denoting the importance of material innovation in neuromorphic computing.
