Informatics and Natural Computation: Final Report

The purpose of this grant is to develop an interdisciplinary course in Informatics and Natural Computation that would service undergraduate computer, natural, and physical science majors. Informatics is the science of information, the practice of information processing, and the engineering of information systems. Informatics studies the structure, algorithms, behavior, and interactions of natural and artificial systems that store, process, access and communicate information. Natural computing refers to a collection of disciplines that unite nature with computing in three distinct ways: 1. Nature serves as a source of inspiration for the development of computational tools or systems that are used for solving complex problems. 2. Computers are used as a means of synthesizing the structural patterns and behaviors of natural phenomena. 3. Natural materials such as those molecules found in nature (e.g. DNA) or those designed by humans (e.g. nanotechnology) are employed as the computers. The logical intersection point between natural computing and the sciences is in the field of bioinformatics, a growing interdisciplinary scientific area aimed at analyzing, interpreting, and managing information from biological data, sequences, and structures. By employing natural computing methods, it is possible to solve bioinformatics problems in classification, clustering, feature selection, data visualization, and data mining

Social Cohesion and Cultural Expressions: The Case of the Sacred Textiles in the Armenian Orthodox Churches of Istanbul

Prologue The social and cultural history of Armenians is long; indeed one cannot fully appreciate its parameters without deeper investigation. This paper reports on a segment of Armenian history— the sacred historical textiles housed in the Armenian Orthodox Churches of Istanbul, Turkey. These artifacts had never before been studied, although a select few objects produced in Istanbul have been published in books devoted to the Armenian collections in Jerusalem, Etchmiadzin (Armenia), and the Sis collection from Anatolia currently in Beirut, Lebanon. Illuminated manuscripts receive the greatest attention among the historical Armenian religious artifacts, followed by stone, metal and wooden objects. Magnificent textiles exist in the aforementioned museum collections but have not been studied in as great a detail as in this endeavor. A book on the material, Splender and Pageantry: Textile Treasures from the Armenian Orthodox Churches of Istanbul (Marchese & Breu), is under contract to be published by fall of 2009. A second book on non-textile objects, Treasures of Faith: Sacred Relics and Artifacts from the Armenian Orthodox Churches of Istanbul (Marchese & Breu) is nearing completion. In 2002 we presented a paper at TSA on the miniature tradition in the textile collections. This paper expands on that work, as we have been studying the collections steadily for over 10 years. The research involved content analysis and ethnographic methodologies in working within the Armenian community in Istanbul

Classical analysis of phase-locking transients and Rabi-type oscillations in microwave-driven Josephson junctions

We present a classical analysis of the transient response of Josephson junctions perturbed by microwaves and thermal fluctuations. The results include a specific low frequency modulation in phase and amplitude behavior of a junction in its zero-voltage state. This transient modulation frequency is linked directly to an observed variation in the probability for the system to switch to its non-zero voltage state. Complementing previous work on linking classical analysis to the experimental observations of Rabi-oscillations, this expanded perturbation method also provides closed form analytical results for attenuation of the modulations and the Rabi-type oscillation frequency. Results of perturbation analysis are compared directly (and quantitatively) to numerical simulations of the classical model as well as published experimental data, suggesting that transients to phase-locking are closely related to the observed oscillations.Comment: 18 pages total, 8 figures (typos corrected; minor revisions to figures and equations

Structural pattern and functional correlations of the long bone diaphyses intracortical vascular system: investigation carried out with China ink perfusion and multiplanar analysis in the rabbit femur.

The intracortical vessel system of the rabbit femur has been studied after perfusion of the vascular tree with a water solution of dye (China ink) with multiplanar analysis. This method utilizes the full depth of field of the microscope objectives focusing different planes of the thick cortex. The microscopic observation even if restricted to a limited volume of cortex allowed to differentiate true 3-D nodes (54.5%) from the superimposition of vessels lying on different planes. The network model with elongated meshes preferentially oriented along the longitudinal axis of the diaphysis in his static configuration is not very different from the vascular anatomy depicted in the 2-D traditional models; however, the semi-quantitative morphometric analysis applied to the former supported the notion of a multidirectional microvascular network allowing change of flow according to the functional requirements. Other peculiar aspects not previously reported were cutting cone loops, blind-end and short-radius-bent vessels, and button-holes figures. The network design and node distribution were consistent with the straight trajectory of the secondary remodeling, with the proximal-to-distal and distal-to-proximal advancement directions of the cutting cones and with two main modes of node formation, namely bifurcation of the cutting cone and interception with pre-existing canals. The general organization of the network and its uninterrupted transformation during bone modeling and remodeling suggested a substantial plasticity of the intracortical vascular system capable to adapt itself to the changeable haemodynamic conditions

500 Year Documentation

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
