Summary: Deforestation caused by human activities is a common issue in Amazonian countries, leading to the formation of complex networks during the deforestation process. Analyzing the local connected fractal dimension helps categorize the complexity of deforested patches and identify thresholds for high and low land transformation.

Summary: China is the largest provider of infrastructure financing to the developing world, but the environmental risks of its projects are not well-known. A study on Chinese-funded road improvements in Cambodia reveals that these projects are disproportionately located in areas with more plantations and have led to significant declines in forest cover, particularly in nearby plantation areas.

Summary: This study analyzes the complexity of brain signals to investigate the functional role of different brain regions during various stages of vigilance. The results show that brain complexity increases with higher levels of vigilance, with the highest complexity observed during wakefulness. The complexity of different brain regions varies across sleep stages.

Summary: The study aimed to derive a generalized fractal feature that operates without iterative box sizes or any linear regression estimators, validate it, and apply it to the classification of detailed organic images of viruses. Results indicate that the proposed method is accurate for known fractals, shows differing trends for color fractals, and can uniquely identify viruses based on their computed fractal features.

Summary: The material basis for soil formation is rock weathering debris. Understanding the particle size composition characteristics of rock weathering debris is important for improving the soil structure in the dry farmland of Ningxia, China. In this study, the particle sizes of weathered debris from grey-green slate were examined after freeze-thaw and dry-wet cycles tests. The results showed that clay, fine silt, and fine sand were the most abundant sizes, and the fractal dimension could accurately represent the particle size distribution of weathered debris.

Summary: The analysis of urban spatial form is fundamental to urban development. Traditional fractal research often focuses on the urban spatial layout, lacking a visually expressive representation of the specific form, characteristics, and development trends of urban architectural spaces. This study simplifies urban architectural forms and establishes correlations between architectural form and fractal dimension. The case study reveals that Zhengzhou City exhibits obvious fractal characteristics in its architectural layout. The combination of two-dimensional and three-dimensional fractal dimensions helps to comprehensively reveal architectural layout information. This study promotes the visualization of fractal theory and its application to spatial gradients, providing theoretical and data references for optimizing urban spatial form.

Summary: This paper investigates the statistical and topological properties of fractional Brownian polymer chains with short-range volume interactions, focusing on collapsed conformations with fractal dimensions greater than or equal to 2 in three-dimensional space, analyzed numerically and through the mean-field Flory approach. The study aims to mimic the conformational statistics of collapsed unknotted polymer rings and simplifies the problem by replacing the topologically stabilized state with a self-avoiding fractal path adjusted to a fractal dimension approximately equal to 3. The research shows that as the fractal dimension increases, typical conformations become more territorial and less knotted, establishing a direct correspondence between the fractal dimension and knotting of fractal paths with finite excluded volume.

Summary: This paper investigates the use of Takens estimator for correlation dimension estimation on a sphere. It shows that using geodetic and Euclidean metrics results in different biases through two analytically tractable cases. The analysis provides a cue for studying fractal geometries in seismology.

Summary: This study investigates the relationship between the box counting (BC) and power law (PL) methods for estimating the fractal dimension of aggregates. The results show that the BC fractal dimension is greater than the PL fractal dimension when the PL fractal dimension is less than or equal to 2.5, and vice versa when the PL fractal dimension is greater than 2.5. The study also proposes a projection method to obtain two-dimensional projection images of the aggregates and establishes correlations between the two-dimensional BC fractal dimension and the three-dimensional and PL fractal dimensions.

Summary: By analyzing the propagation of a Huygens front in turbulent conditions, a bifractal model is proposed to explain the relationship between the length scale of the smallest wrinkles on the front surface and the speed of the front, based on the hypothesis of dynamical similarity. The model suggests a linear relation between the mean fluid consumption velocity and the rms turbulent velocity, even when the ratio of front speed to turbulent velocity tends to zero.

Summary: Road-infrastructure projects are rapidly expanding worldwide, posing a threat to undisturbed forests. The study manually mapped existing and proposed roads, calculated the impact on forest loss, and identified optimal routes to minimize environmental and financial costs using least-cost-path analysis.

Summary: This paper examines the impact of road-building on local economic development and regional inequality. The findings suggest that early access to roads promoted local economic development, but geographical factors and earlier economic development played a larger role in shaping the spatial pattern of development.
