Causality in Reversed Time Series: Reversed or Conserved?

Jakub Kořenek, Jaroslav Hlinka
2021 Entropy  
We start with a theoretical analysis that demonstrates that a perfect coupling reversal under time reversal occurs only under very specific conditions, followed up by constructing low-dimensional examples  ...  Finally, simulations of random as well as realistically motivated network coupling patterns from brain and climate show that level of coupling reversal and conservation can be well predicted by asymmetry  ...  Acknowledgments: We thank Nikola Jajcay, David Hartman, and David Tomecek for valuable help with example data preparation.  ...

Conceptual Models as Hypotheses in Monitoring Urban Landscapes

Todd R. Lookingbill, Robert H. Gardner, Philip A. Townsend, Shawn L. Carter
2007 Environmental Management  
Academics generally prefer a bottomup approach to model construction that emphasizes ecologic theory and process, whereas managers often use a top-down approach that takes advantage of existing information  ...  An example application of the process to a network of national parks in and around Washington, DC illustrates the ability of the approach to systematically identify monitoring data that would both advance  ...  The symbols for Figure 5 are courtesy of the Integration and Application Network (, University of Maryland Center for Environmental Science.  ...
