Structural Complexity and Informational Transfer in Spatial Log-Gaussian Cox Processes
Entropy, 2021 The doubly stochastic mechanism generating the realizations of spatial log-Gaussian Cox processes is empirically assessed in terms of generalized entropy, divergence and complexity measures.

Fabrication of Spatially Confined Complex Oxides [PDF]
Journal of Visualized Experiments, 2013 Complex materials such as high Tc superconductors, multiferroics, and colossal magnetoresistors have electronic and magnetic properties that arise from the inherent strong electron correlations that reside within them. These materials can also possess electronic phase separation in which regions of vastly different resistive and magnetic behavior can ...

Information and complexity analysis of spatial data
Spatial Statistics, 2021 Information Theory provides a fundamental basis for analysis, and for a variety of subsequent methodological approaches, in relation to uncertainty quantification. The transversal character of concepts and derived results justifies its omnipresence in scientific research, in almost every area of knowledge, particularly in Physics, Communications ...

Low-complexity transmit antenna selection for spatial modulation
, 2015 A low-complexity transmit antenna selection (TAS) scheme is proposed for spatial modulation systems to provide a better trade-off between computational complexity and system performance.

Spatial modulation aided zero-padded single carrier transmission for dispersive channels [PDF]
, 2013 In this paper, we consider spatial modulation (SM) operating in a frequency-selective single-carrier (SC) communication scenario and propose zero-padding instead of the cyclic-prefix considered in the existing literature.

The study of fractals among ecologists=O estudo dos fractais entre os ecólogos [PDF]
Acta Scientiarum: Biological Sciences, 2012 Fractals seemed to have permeated most scientific fields, including ecology. In fact, biodiversity and ecological processes are affected by spatial complexity, and fractals can help understand patterns at multiple scales.

Spatiotemporal Permutation Entropy as a Measure for Complexity of Cardiac Arrhythmia
Frontiers in Physics, 2018 Permutation entropy (PE) is a robust quantity for measuring the complexity of time series. In the cardiac community it is predominantly used in the context of electrocardiogram (ECG) signal analysis for diagnoses and predictions with a major application ...

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
