    • Four Centuries of Change in Northeastern United States Forests 

      Thompson, Jonathan R.; Carpenter, Dunbar N.; Cogbill, Charles V.; Foster, David R. (Public Library of Science, 2013)
      The northeastern United States is a predominately-forested region that, like most of the eastern U.S., has undergone a 400-year history of intense logging, land clearance for agriculture, and natural reforestation. This ...
    • Point Charges Optimally Placed to Represent the Multipole Expansion of Charge Distributions 

      Anandakrishnan, Ramu; Baker, Charles; Izadi, Saeed; Onufriev, Alexey V. (Public Library of Science, 2013)
      We propose an approach for approximating electrostatic charge distributions with a small number of point charges to optimally represent the original charge distribution. By construction, the proposed optimal point charge ...
