Considerable Detail

The University of California has been actively designing a ten meter telescope (TMT) for optical and infrared groundbased astronomical observations since 1977. The project, now developed in considerable detail, is described in a series of Ten Meter Telescope Reports, technical notes, and publications (see, for example, Nelson 1980,1981,1982). In order to achieve an acceptable cost for the project, the design departs substantially from conventional telescope designs. Recognizing that the cost is roughly proportional to the weight of the structure and to the enclosed volume, we have made the reduction of weight and size a high priority goal of the design. To achieve these objectives a light-weight segmented primary mirror was designed. The parabolic primary is a mosaic of 36 hexagonal segments. In addition, the primary focal ratio is f/1.75, thus resulting in a short telescope tube; this allows a very compact dome.

Abstract Interview with Derek Conrad Murray, professor of history of art and visual culture at the University of California, Santa Cruz. Murray discusses his new book, Mapplethorpe and the Flower: Radical Sexuality and the Limits of Control (2020), selfies, and the present and future potentials and limitations of visual studies.

The Impact

Watch the VIDEO.At this time of rapid advancements in scholarly communication, publishers must increasingly find new ways to respond and adapt to researcher needs. However current technological infrastructure in the industry is not built to be agile or easily customizable. We must look beyond the inflexible, restrictive, and costly technology silos we currently have, evaluate our workflows, and learn from other industries to pursue community-owned, collaborative solutions. How can open source technology equip us in our pursuit of efficient, sustainable publishing that can evolve with research communication practices? Can we aggregate and share the cost of building core tools, refocusing our technology investments instead into the customizations and enhancements needed to befit researcher requirements, all in the framework of open source? In this presentation we will outline the significance of open source infrastructure to Hindawi’s mission and vision, and the importance of partnering with like-minded organizations to drive change for the industry. We will present the work that Hindawi has undertaken in collaboration with the Coko Foundation, eLife, and the University of California Press to evolve xPub—a modular open source architecture, configurable in a variety of arrangements to provide a host of workflow solutions for publishers—and consider the impact that the adoption and integration of xPub can have for publishers, societies, and institutions worldwide.

ABSTRACTHere we describe a relatively quick, simple, economical and accurate laboratory developed test (LDT) for detection of SARS-CoV-2 in heated and diluted saliva samples without RNA extraction. Our protocol is a variation of the University of Illinois Urbana-Champaign SHIELD LDT. Differences include chilling of the samples during dilution and using a reduced volume for the qRT-PCR reactions. The level of detection for our LDT is 3125 copies/ml, which compares favorably with other saliva-based tests. Initial validation studies with a limited number of patient samples have demonstrated excellent agreement between results using our LDT and those obtained from external laboratories. The cost of consumables for our test is under $8 and a throughput of 1000 tests/day can be achieved with 3-4 personnel.

Abstract:The development of an innovative clinical decision-support project such as the University of Minnesota’s Clinical Workstation initiative mandates the use of modern client-server network architectures. Preexisting conventional laboratory information systems (LIS) cannot be quickly replaced with client-server equivalents because of the cost and relative unavailability of such systems. Thus, embedding strategies that effectively integrate legacy information systems are needed. Our strategy led to the adoption of a multi-layered connection architecture that provides a data feed from our existing LIS to a new network-based relational database management system. By careful design, we maximize the use of open standards in our layered connection structure to provide data, requisition, or event messaging in several formats. Each layer is optimized to provide needed services to existing hospital clients and is well positioned to support future hospital network clients.

The California missions, whose original church spaces and visual programs were produced by Iberian, Mexican, and Native artisans between 1769 and 1823, occupy an ambiguous chronological, geographical, and political space. They occupy lands that have pertained to conflicting territorialities: from Native nations, to New Spain, to Mexico, to the modern multicultural California. The physical and visual landscapes of the missions have been sites of complex and often incongruous religious experiences; historical trauma and romantic vision; Indigenous genocide, exploitation, resistance, and survivance; state building and global enterprise. This Dialogues section brings together critical voices, including especially the voices of California Indian scholars, to interrogate received models for thinking about the art historical legacies of the California missions. Together, the contributing authors move beyond and across borders and promote new decolonial strategies that strive to be responsive to the experience of California Indian communities and nations. This conversation emerges from cross-disciplinary relationships established at a two-day conference, “‘American’ Art and the Legacy of Conquest: Art at California’s Missions in the Global 18th–20th Centuries,” sponsored by the Terra Foundation for American Art and held at the University of California, Los Angeles, in November 2019.
