The study of fractals among ecologists - doi: 10.4025/actascibiolsci.v34i1.7701

open access: yesActa Scientiarum: Biological Sciences, 2011
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.

Implications of Panarchy for ecosystem service research: the role of system dynamics in service delivery

open access: yesEcology and Society, 2022
Panarchy illustrates the dynamic nature of social-ecological systems and their nestedness and interconnectedness through time and space. Although there have been great advances in ecosystem service (ES) research, it has only rarely integrated dynamic ...

Complex delay dynamics on railway networks from universal laws to realistic modelling

open access: yesEPJ Data Science, 2018
Railways are a key infrastructure for any modern country. The reliability and resilience of this peculiar transportation system may be challenged by different shocks such as disruptions, strikes and adverse weather conditions. These events compromise the

How Many Gammas? Redefining Hippocampal Theta-Gamma Dynamic During Spatial Learning

open access: yesFrontiers in Behavioral Neuroscience, 2022
The hippocampal formation is one of the brain systems in which the functional roles of coordinated oscillations in information representation and communication are better studied. Within this circuit, neuronal oscillations are conceived as a mechanism to

Soil Spatial Complexity

open access: yes, 2022
This study is aimed at analysing the effects of tree disturbances produced by treethrows on the spatial variability of soil chemical properties and on soil formation to explain the spatial pedocomplexity in one of the oldest forest reserves in Europe.

Reducing Spatial Data Complexity for Classification Models [PDF]

open access: yes, 2007
Intelligent data analytics gradually becomes a day-to-day reality of today's businesses. However, despite rapidly increasing storage and computational power current state-of-the-art predictive models still can not handle massive and noisy corporate ...

Query processing of spatial objects: Complexity versus Redundancy [PDF]

open access: yes, 1993
The management of complex spatial objects in applications, such as geography and cartography, imposes stringent new requirements on spatial database systems, in particular on efficient query processing. As shown before, the performance of spatial query

Low-complexity Signal Detection for Spatial Modulation [PDF]

open access: yesJisuanji gongcheng, 2018
At receiver,Space Modulation(SM) algorithm always uses Maximum Likelihood(ML) signal detection to obtain the transmission antenna number and the modulation signal and restore the transmitted information bit.However,the complexity of ML algorithm ...
