    The Neighborhood’s Catalogue: Lower East Side Planning and Design File

    This catalogue was designed to support the process of slow redevelopment over time, combined with conservation of diverse social and historical continuity and the exploration of new land and building uses. The catalogue shows how to involve neighborhoods in participation, supportive design, incremental planning and phased development. This project was made possible by a grant from the National Endowment for the Arts. Reprinted in 1987.https://dc.uwm.edu/caupr_mono/1047/thumbnail.jp

    Making Every Photon Count: A Quantum Polyspectra Approach to the Dynamics of Blinking Quantum Emitters at Low Photon Rates Without Binning

    Full text link
    The blinking statistics of quantum emitters and their corresponding Markov models play an important role in high resolution microscopy of biological samples as well as in nano-optoelectronics and many other fields of science and engineering. Current methods for analyzing the blinking statistics like the full counting statistics or the Viterbi algorithm break down for low photon rates. We present an evaluation scheme that eliminates the need for both a minimum photon flux and the usual binning of photon events which limits the measurement bandwidth. Our approach is based on higher order spectra of the measurement record which we model within the recently introduced method of quantum polyspectra from the theory of continuous quantum measurements. By virtue of this approach we can determine on- and off-switching rates of a semiconductor quantum dot at light levels 1000 times lower than in a standard experiment and 20 times lower than achieved with a scheme from full counting statistics. Thus a very powerful high-bandwidth approach to the parameter learning task of single photon hidden Markov models has been established with applications in many fields of science

    Landscape science: a Russian geographical tradition

    Get PDF
    The Russian geographical tradition of landscape science (landshaftovedenie) is analyzed with particular reference to its initiator, Lev Semenovich Berg (1876-1950). The differences between prevailing Russian and Western concepts of landscape in geography are discussed, and their common origins in German geographical thought in the late nineteenth and early twentieth centuries are delineated. It is argued that the principal differences are accounted for by a number of factors, of which Russia's own distinctive tradition in environmental science deriving from the work of V. V. Dokuchaev (1846-1903), the activities of certain key individuals (such as Berg and C. O. Sauer), and the very different social and political circumstances in different parts of the world appear to be the most significant. At the same time it is noted that neither in Russia nor in the West have geographers succeeded in specifying an agreed and unproblematic understanding of landscape, or more broadly in promoting a common geographical conception of human-environment relationships. In light of such uncertainties, the latter part of the article argues for closer international links between the variant landscape traditions in geography as an important contribution to the quest for sustainability

    People Mapping: Finding and Using Demographic Data

    No full text
    This video workshop, from the 2021 Esri Education Summit, teaches participants about finding and using demographic data for more than 130 countries. In the video, Joseph Kerski outlines the demographic and socio-economic variables that are available through the ArcGIS Living Atlas of the World, explores the differences between U.S. Census data and Esri demographics, discusses geoliteracy, and covers other tips and steps for using demographic data with Esri tools and resources. Workshop goals include the following: find spacial and attribute data for populations and demographics; use population data in ArcGIS Pro, ArcGIS Online, and other Esri tools; learn about the kinds of investigations that users can foster with these tools and data sets; and learn about lessons and resources to learn more.The video recording runs 47:41 minutes in length. Additional videos from the summit are available to view separately
