Summary: The research combines the origin of probability distribution functions with power law tails, introducing a novel class of nonlinear self-excited point processes and revealing a new mechanism for power laws, including Zipf's law, providing a new understanding of their ubiquity.

Summary: Mining-induced ground movement is a complex nonlinear process and a regional geological hazard. By analyzing GPS monitoring data from the Jinchuan Nickel Mine in China over a period of 14.5 years, this study found that the ground-movement time series exhibited power-law behavior and complex periodicity. The results provide a basis for predicting land subsidence in the study area.

Summary: We generalize Taylor's law to heavy-tailed distributions with tail index alpha in (0, 1) and infinite mean, demonstrating specific relationships between sample statistics and sample mean as sample size increases. These scaling relationships characterize the risk-adjusted performance of investments and are known as Taylor's law in ecology and fluctuation scaling in physics.

Summary: While the impact of water availability on vegetation and soil microbial activity is well understood, the influence of aridity on carbon patterns in ecosystems is not fully known. Through dimensional analysis and scaling of global terrestrial carbon stocks, we find a self-similar behavior with the dryness index, indicating a strong coupling between the hydrological cycle and biogeochemical process. When normalized by the corresponding hydroclimatic regime, the carbon stock distributions collapse into a double Pareto lognormal distribution, highlighting similarities with income distribution in economics.

Summary: This study reveals the existence of scaling transformations among the transmission curves in a self-affine golden structure based on graphene. The use of the golden ratio as the energy scaling factor implies the presence of scaling transformations for different self-affine graphene-based systems.

Summary: We study a network model in which the spatial constraint changes with the network growth and find that the dynamic constraint generally leads to a non-stationary multiple scaling law in degree distribution. Specifically, we demonstrate the successive emergence of different power-law segments during the network evolution, from a single power law at the beginning to a double one and to more scaling laws due to the model setting. Our findings suggest a plausible geometric origin of the double power-law distribution and predict its non-stationary nature accompanied by its emergence, which are supported by our empirical study on the Chinese airline network.

Summary: The study reveals that frequency-rank data of animal behaviors in nature follow scale-invariant power law behavior at the population level, showing consistent patterns even with variations in location and season. Robust self-similarity patterns are observed at different scales, indicating the possibility of designing predictive models of behavior and exploring syntax in a species' overall behavioral repertoire.

Summary: Long-range temporal correlations have significant effects on the dynamic scaling of growing surfaces, leading to noticeable changes in surface morphologies and the development of faceted patterns on KPZ surfaces as the temporal correlation exponent increases. The results show nontrivial dynamic properties of the temporally correlated KPZ system, with characteristic roughness exponents satisfying certain conditions and non-universal scaling of alpha (loc) within local window sizes.

Summary: This study reveals that the energy dissipation rate in a nonequilibrium reaction system has an inverse power-law dependence on the number of microscopic states in a coarse-grained state, and requires self-similarity of the underlying network. The scaling exponent of the dissipation law depends on the network structure and the probability flux correlation. The existence of the inverse dissipation scaling law is demonstrated in realistic biochemical systems such as biochemical oscillators and microtubule-kinesin active flow systems.

Summary: This paper discusses the measurement of long-range correlations in neural and behavioral activity and their implications. Researchers often use power-law scaling as evidence of critical states and soft assembly, but face criticism. The authors propose a more principled understanding of criticality based on Integrated Information Theory, suggesting that critical integration is more informative than power-law measures.

Summary: This article examines the complexity of urban space by looking at the fractal forms and scaling statistics of clustered street junctions in Beijing and Shenzhen. The analysis shows that power law distribution applies to the four urban attributes, but varies in terms of exponents and ht-index values. The study also explores the allometric relationships between urban configuration and function.

Summary: The study models the time evolution of the mean and variance of nonstationary time series using path integral formalism to obtain temporal fluctuation scaling in complex systems. Analytical expressions describing the temporal evolutions of the mean and variance in terms of cumulants are derived, showing a general analytical relation between the variance and mean that satisfies a power law with the exponent being a function of time. The path integral approach's findings on financial time series are consistent with empirical data regarding the temporal evolution of mean and variance, temporal fluctuation scaling, and exponent evolution.

Summary: This paper proposes an impedance based model reference adaptive system (Z-MRAS) scheme for power sharing in islanded microgrids. By estimating the impedance angle between distributed generators (DGs), the proposed scheme aims to enhance the proportional apparent power sharing between DGs in islanded mode.

Summary: Despite the neglect of the high and low dimensions in candlestick chart data, this research computed stylized facts for open, close, high, and low price series, and found that in the vast majority of cases these series do not come from the same distribution. Taking high and low dimensions into account in econophysics can enhance our understanding of market dynamics and be beneficial for trading models.
