Comment on "Scaling of atmosphere and ocean temperature correlations in observations and climate models"

, 2003
In a recent letter [K. Fraedrich and R. Blender, Phys. Rev. Lett. 90, 108501 (2003)], Fraedrich and Blender studied the scaling of atmosphere and ocean temperature.

The value of regeneration for insect fauna associated with leaf litter in the Brazilian savanna: A comparative study of biomass and trophic structure

Annals of Applied Biology, EarlyView.
This study demonstrates the ecological value of natural regeneration in the Brazilian Cerrado by analysing the biomass, richness and trophic structure of leaf litter insects across pasture (P), regenerating (R) and native (N) areas. We found that R areas supported insect communities more similar to N habitats than to Ps, with higher richness, greater ...

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.

Species‐Specific Genetic Patterns in Sympatric Freshwater Turtles Challenge a Generalized Multi‐Species Conservation Approach

Animal Conservation, EarlyView.
We compared genetic diversity and spatial genetic structure in the snapping turtle (Chelydra serpentina; left panel), Blanding's turtle (Emydoidea blandingii; bottom right), and spotted turtle (Clemmys guttata; top right) sampled in areas of co‐occurrence across ~49,160 km2.

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) ~

Radio Frequency Fingerprinting for WiFi Authentication Based on Detrended Fluctuation Analysis

IET Information Security
Traditional physical-layer authentication (PLA) approaches primarily rely on a limited set of hardware features, which restricts their robustness and accuracy in dynamic wireless environments.

Measuring the time‐varying market efficiency in the prewar and wartime Japanese stock market, 1924–1943

Asia‐Pacific Economic History Review, Volume 65, Issue 1, Page 131-159, March 2025.
Abstract This study examines the adaptive market hypothesis in the prewar and wartime Japanese stock market using a new market capitalization‐weighted price index. First, we find that the degree of market efficiency varies over time and with major historical events. This implies that the hypothesis is supported in this market.

Three shades of self‐regulation with unique complex dynamics, drivers and targets for intervention

British Journal of Educational Technology, EarlyView.
Abstract Self‐regulated learning (SRL) is an active process involving multiple interacting components that evolve over time, exhibiting characteristics of complex systems such as non‐linearity, emergent behaviour, self‐organization, and hierarchy. These interactions unfold at different temporal levels, each warranting a dedicated lens to capture their ...
