    Museum visitors today can regularly view 500 year old art by Renaissance masters. Will visitors to museums 500 years in the future be able to see the work of digital artists from the early 21st century? This paper considers the real problem of conserving interactive digital artwork for museum installation in the far distant future by exploring the requirements for creating documentation that will support an artwork\u27s adaptation to future technology. In effect, this documentation must survive as long as the artwork itself -- effectively, in perpetuity. A proposal is made for the use of software engineering methodologies as solutions for designing this documentation

    Fast label-free multilayered histology-like imaging of human breast cancer by photoacoustic microscopy

    The goal of breast-conserving surgery is to completely remove all of the cancer. Currently, no intraoperative tools can microscopically analyze the entire lumpectomy specimen, which results in 20 to 60% of patients undergoing second surgeries to achieve clear margins. To address this critical need, we have laid the foundation for the development of a device that could allow accurate intraoperative margin assessment. We demonstrate that by taking advantage of the intrinsic optical contrast of breast tissue, photoacoustic microscopy (PAM) can achieve multilayered histology-like imaging of the tissue surface. The high correlation of the PAM images to the conventional histologic images allows rapid computations of diagnostic features such as nuclear size and packing density, potentially identifying small clusters of cancer cells. Because PAM does not require tissue processing or staining, it can be performed promptly and intraoperatively, enabling immediate directed re-excision and reducing the number of second surgeries

    Feasibility study ASCS remote sensing/compliance determination system

    Get PDF
    A short-term technical study was performed by the MSC Earth Observations Division to determine the feasibility of the proposed Agricultural Stabilization and Conservation Service Automatic Remote Sensing/Compliance Determination System. For the study, the term automatic was interpreted as applying to an automated remote-sensing system that includes data acquisition, processing, and management

    Experimental and Creative Approaches to Collecting and Distributing New Media Art within Regional Arts Organisations

    Get PDF
    This article is an overview of preliminary research undertaken for the creation of a framework for collecting and distributing new media art within regional art galleries in the U.K. From the 1960s, artists have experimented using computers and software as production tools to create artworks ranging from static, algorithmic drawings on paper to installations with complex, interactive and process-oriented behaviours. The art-form has evolved into multiple strands of production, presentation and distribution. But are we, as collectors, researchers, artists and enthusiasts facing an uncertain future concerning the integration of new media art into institutional cultural organisations? Recently, concerns have been raised by curators regarding the importance of learning how to collect new media art if there is to be any hope of preserving the artworks as well as their histories. Traditional collections management approaches must evolve to take into account the variable characteristics of new media artworks. As I will discuss in this article, although regarded as a barrier to collecting new media artworks, artists and curators at individual institutions have recently taken steps to tackle curatorial and collections management activities concerning the often unpredictable and unstable behaviours of new media artworks by collaboration and experimentation. This method has proved successful with some mainstream, university and municipal galleries prior to acquiring or commissioning new artworks into their collections. This paper purports that by collaboration, experimentation and the sharing of knowledge and resources, these concerns may be conquered to preserve and make new media art accessible for future generations to enjoy and not to lament over its disappearance

    A Type of Preservation: Modern Recreations of Typeface at Genesee Country Village & Museum and the Cary Graphics Art Collection

    Get PDF
    Historical objects that serve educational and interpretive purposes face frequent use and can easily be damaged, particularly when those objects are designed to be disposed of following high usage. Conserving these artifacts through both digital and physical reproductions enables museum staff, scholars, and the general public to tell a more complete history of the objects and of material culture. To demonstrate the necessity of preserving functional artifacts, this thesis examined historic wooden typefaces used for document printing to answer the following question: do digital and physical reproductions of wood type fonts allow for preservation of the original fonts while maintaining an authentic, participatory experience for visitors? By working with the collection of typefaces at Genesee Country Village & Museum in Mumford, New York and the Cary Graphic Art Collection at Rochester Institute of Technology, I recreated damaged types with methods tested by scholars of printing history to demonstrate the value of physical and digital reproductions. I also showed how such efforts enable museums and other collecting institutions to view type as both an art form and a means of production. This research contributes to the ongoing discussion on the use of facsimiles in the museum space for exhibition and educational purposes and the conversations surrounding authenticity in museums

    SchNet: A continuous-filter convolutional neural network for modeling quantum interactions

    Get PDF
    Deep learning has the potential to revolutionize quantum chemistry as it is ideally suited to learn representations for structured data and speed up the exploration of chemical space. While convolutional neural networks have proven to be the first choice for images, audio and video data, the atoms in molecules are not restricted to a grid. Instead, their precise locations contain essential physical information, that would get lost if discretized. Thus, we propose to use continuous-filter convolutional layers to be able to model local correlations without requiring the data to lie on a grid. We apply those layers in SchNet: a novel deep learning architecture modeling quantum interactions in molecules. We obtain a joint model for the total energy and interatomic forces that follows fundamental quantum-chemical principles. This includes rotationally invariant energy predictions and a smooth, differentiable potential energy surface. Our architecture achieves state-of-the-art performance for benchmarks of equilibrium molecules and molecular dynamics trajectories. Finally, we introduce a more challenging benchmark with chemical and structural variations that suggests the path for further work

    Identification of the Sequence of Steps Intrinsic to Spheromak Formation

    Get PDF
    A planar coaxial electrostatic helicity source is used for studying the relaxation process intrinsic to spheromak formation Experimental observations reveal that spheromak formation involves: (1) breakdown and creation of a number of distinct, arched, filamentary, plasma-filled flux loops that span from cathode to anode gas nozzles, (2) merging of these loops to form a central column, (3) jet-like expansion of the central column, (4) kink instability of the central column, (5) conversion of toroidal flux to poloidal flux by the kink instability. Steps 1 and 3 indicate that spheromak formation involves an MHD pumping of plasma from the gas nozzles into the magnetic flux tube linking the nozzles. In order to measure this pumping, the gas puffing system has been modified to permit simultaneous injection of different gas species into the two ends of the flux tube linking the wall. Gated CCD cameras with narrow-band optical filters are used to track the pumped flows

    Revealing the Archetype: The Journey of a Trecento Madonna and Child at the National Museum of Scotland

    Get PDF
    The National Museums Scotland Madonna and Child project sought to uncover and document the history of a fine polychrome wood carving attributed to The Master of the Gualino St Catherine and to prepare it for display. A new body of knowledge has been assembled by the interdisciplinary team. The conservation treatment was informed by this work and led to further discoveries: the removal of overpaint exposing a previously hidden underdrawing. The ethics of the treatment decisions, including the removal of the Christ Child’s 1960s’ fingers required team dialogue and was opened up for the public to respond to in a series of blogs. The discovery of a rich polychromy including gold and glazed tin has led to further plans to produce a 3-D colour reconstruction. The collaborations developed during this project will facilitate future joint ventures for polychrome sculpture in Scottish collections

    Camel Anatomy; More Than Just a Hump

    Get PDF
    The one-humped camel (Camelus dromedarius) is capable of living in extreme, arid environments due to its numerous anatomical adaptations. Its modified features of the muscular system, integument, skeletal system, and several internal organs allow this animal to survive in such harsh environmental conditions. Many of these adaptations allow for conservation of energy and water as well as improvement of locomotion to acquire scarce resources. In this paper we will look more closely at some of these adaptations and determine their function in promoting the survival and reproduction of the one-humped camel in desert environments
