Socioanthropological Synthesis of Ethological Studies on Rituals in Non-Human Species

Forest structure indicators based on tree size inequality and their relationships to airborne laser scanning

Rubén Valbuena
2015 Dissertationes Forestales  
The first CCA component was more related to the dominant canopy, and therefore it influences the ALS surveys to a greater extent.  ...  It was also demonstrated in Section 2.2 and Study I that they relate directly to the Lorenz curve.  ...

New Results on the Thermodynamic Properties of the Climate System

Valerio Lucarini, Klaus Fraedrich, Francesco Ragone
2011 Journal of the Atmospheric Sciences  
Using 2D fields at the top of atmosphere alone, we derive lower bounds to the rate of material entropy production and to the intensity of the Lorenz energy cycle.  ...  It is found that about 90% of the material entropy production is due to vertical processes such as convection, whereas the large scale meridional heat transport contributes only about 10%.  ...  to vertical processes is dominant by about one order of magnitude.  ...

Dynamical Properties of Model Output Statistics Forecasts

S. Vannitsem, C. Nicolis
2008 Monthly Weather Review  
Analytical and numerical investigations of low-order systems displaying chaos indicate that MOS schemes are able to partly correct the impact of both initial and model errors on model forecasting.  ...  Furthermore, the amplitude of the MOS correction depends strongly on the statistical properties of the phase space velocity difference between the model and reference systems, such as its mean and its  ...  This work is partly supported by the European Commission under Contract 12975 (NEST) and the Belgian Federal Science Policy Office under Contract MO/34/ 017.  ...

2012 Frontiers in Computational Neuroscience  
The method yields temporal sequences of networks which permits to trace the evolution of the functional connectivity during the time course of the observation.  ...  Yet estimating functional networks from measured signals is not trivial, especially if the data is non-stationary and noisy as it is often the case with physiological recordings.  ...  ACKNOWLEDGMENTS The authors would like to thank Romy Frömer and Ulrike Bunzenthal for assistance in running the experiments.  ...
