Summary: In this study, the attribute information of underground utilities and history information of ground subsidence were collected to develop a prediction model. Spatial lag model (SLM) was selected as suitable for analyzing the vulnerability of ground subsidence, and the density of underground utilities was found to be the highest influencing factor. A vulnerability map of ground subsidence in the target area was prepared using the model.

Summary: This study investigates the nonlinearity and spatial transmission mechanism between financial development and pollutant emissions across regions in China. The results show spatial spillover effects on pollutant emissions, with financial development reducing SO2 emissions in a particular region but significantly increasing them in surrounding regions. However, financial development significantly decreases SW emissions in a particular region without significant impact on its surrounding regions.

Summary: The analysis of the spatial-temporal characteristics and regional differences in the carbon emissions efficiency of the freight transport industry is crucial for developing effective carbon reduction policies. This study measures and analyzes the carbon emissions efficiency of the freight transport industry in 31 Chinese provinces from 2008 to 2019, finding low overall levels with regional disparities, higher in the east than in the west. Furthermore, the study highlights the significant spatial diffusion and inhibition effects in adjacent areas, emphasizing the importance of considering spatial factors in improving carbon emissions efficiency.

Summary: Early detection of the spatial expansion pattern of alien plants and the associated environmental factors is crucial for their management. Regression kriging and geographically weighted regression were used in this study to estimate the critical environmental factors related to the invasion of Hypochaeris radicata into new habitats. The results indicate that human activities and roads are the primary factors driving the expansion of H. radicata, while forest areas have not been invaded.

Summary: A new spatial autoregressive geographically weighted quantile regression method was proposed in this study to address the shortcomings of standard hedonic regression models. Comparing with mean and quantile hedonic regressions, the results showed that the proposed method outperforms other models in terms of fitting accuracy, especially at the tails of the dependent variable distribution. Policy recommendations for the development of private residential rental markets were provided based on the findings, which incorporate spatial effects and price segment requirements.

Summary: Understanding the spatial-temporal variation of soil pH is crucial for agricultural production. In a hilly and mountainous region in southwestern China, the topography significantly influenced the spatial distribution of soil pH, with factors like organic fertilizer, slope, valley depth being important in pH variation. From 2012 to 2017, the average soil pH increased by 0.63, with differences attributed to organic fertilizer application and topography.

Summary: The study utilized an integrated modeling approach to investigate the linkages between landscape-related features and high arsenic levels in river sediments in central Iran. Results showed that sediment arsenic levels were influenced by the density of agricultural activities near the river outlet and the proportion of silty loam or loamy soils, providing important insights for policy decisions regarding river contamination processes in central Iran.

An overlooked interval emerges as the best-performing approximate interval for small samples. This approach is simple, intuitive, and illuminating, and may hold pedagogical value for instructors of advanced courses on statistical inference.

Summary: This paper studies the sets of visit times to points on the plane by a standard two-dimensional Brownian motion. The concept of logarithmic scale Minkowski dimension is introduced as a tool for measuring these sets. It is proved that almost surely there exists a point x such that the logarithmic scale Minkowski dimension of the set of visit times to x is 1.

Summary: In this paper, we study a one-dimensional stochastic differential equation obtained by performing a random time change of the backward Loewner dynamics in H. We show the convergence of this equation towards its stationary measure in the sense of random ergodic averages. The density formula of the stationary measure reveals a phase transition at W = 8, which coincides with the change in behavior of the SLEW trace. By using convergence in total variation, we identify families of random times on which the law of the arguments of points under the backward SLEW flow converges to a closed form expression measure.

Summary: We present Azuma-Hoeffding bounds for a class of urn models, which show exponentially decreasing probabilities of being away from the limit. The method involves relating the variables to linear combinations using eigenvectors of the replacement matrix, and introduces appropriate martingales. Some cases of repeated eigenvalues are also considered using cyclic vectors. Moreover, the strong convergence of proportions is proved as an application of these bounds.
