Multifractal detrended fluctuation analysis of hydroclimatic series across Uganda in East Africa

Hydrology Research
This study applied Multifractal Detrended Fluctuation Analysis (MFDFA) to investigate the scaling behaviour of streamflow, precipitation, and potential evapotranspiration (PET) in nine Ugandan catchments during 1990–2013.

Nonlinear analysis of electroencephalogram signals while listening to the holy Quran

Journal of Medical Signals and Sensors, 2019
Background: Electrical activity of the brain, resulting from electrochemical signaling between neurons, is recorded by electroencephalogram (EEG). The neural network has complex behavior at different levels that strongly confirms the nonlinear nature of ...

Edges as ecological filters: Asymmetrical orientation‐specific arthropod activity across forest boundaries

Insect Science, EarlyView.
Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Alpha band oscillations in common synaptic input are explanatory of the complexity of isometric knee extensor muscle torque signals

Experimental Physiology
We investigated whether the strength of oscillations in common synaptic input was explanatory of knee extensor (KE) torque signal complexity during fresh and fatigued submaximal isometric contractions, in adults aged from 18 to 90 years.

Seismic Signaling Associated With Breeding‐Season Spatial Behavior in the Subterranean Plateau Zokor

Integrative Zoology, EarlyView.
Eospalax baileyi shows seismic signals associated with nasal‐pad striking and corpuscle‐like structures potentially relevant to mechanosensation. Artificial seismic disturbance was based on the temporal structure of breeding‐season recordings, and pregnancy prevalence was 3/10 in the interference plot and 8/10 in the control plot.

Correlação em séries temporais de temperatura na região de Cascavel, Estado do Paraná = Correlation in temperature time series in Cascavel, Paraná State

Acta Scientiarum: Technology, 2007
Temperaturas podem ser correlacionadas por funções tipo leis de potência, e o termo de persistência pode ser caracterizado por uma função de autocorrelação C(t) de variações de temperatura, e t é o tempo entre as observações. Esta função decai como C(t) ~
