The structural properties of evolving random graphs are investigated. Treating linking as a dynamic aggregation process, rate equations for the distribution of node to node distances (paths) and of cycles are formulated and solved analytically. At the gelation point, the typical length of paths and cycles, l , scales with the component size k as l approximately k(1/2) . Dynamic and finite-size scaling laws for the behavior at and near the gelation point are obtained. Finite-size scaling laws are verified using numerical simulations.

Changes in water, energy, and food (WEF) trade patterns may reshape water circulation patterns, leading to potential water supply and demand risks. Analysis of virtual water risk transmission characteristics and driving factors from the perspective of WEF trade is highly important for alleviating the risk of water shortages and promoting the efficient use of resources. In this paper, a set of methods for quantifying risk transmission values is constructed on the basis of China's interregional input-output model, and the key paths of interregional virtual water risk transmission caused by WEF trade are identified using innovative methods.

Changing land use is one of the main factors influencing global climate change and the imbalance in the carbon cycle. Consequently, the focus of international organizations and the academic community is on strategies to mitigate carbon emissions or improve carbon sequestration by optimizing land use structure and function. Since 2019, China's Zhejiang Province has implemented a township-level pilot policy, exploring a comprehensive land consolidation (CLC for short) pilot policy that includes all elements of "mountains, rivers, forests, farmlands, lakes, and grasslands.

Background/objectives: Riding a bicycle is a foundational movement skill that can be acquired at an early age. The most common training bicycle has lateral training wheels (BTW). However, the balance bike (BB) has consistently been regarded as more efficient, as children require less time on this bike to successfully transition to a traditional bike (TB).
