A recent project, as yet unpublished, has explored representing asymmetric proximity relationships using directed trees.
First, the spatial proximity relationships between spatial point events are roughly captured by Delaunay triangulation.
Then, three-level constraints are described and used to refine spatial proximity relationships with the consideration of statistical characteristics.
Delaunay triangulation with edge length constraints is first employed for modeling the spatial proximity relationships among spatial objects.
In the area of statistical methodology, I have been working on a long-term project on representing asymmetric proximity relationships using directed trees.
Results are in particular useful for practitioners or researchers who would like to enhance their quantitative and visual understanding of operational construction resource activity monitoring and analysis, and in the specific domain of detecting and mapping spatial temporal proximity relationships of near miss events.

The UDI framework utilizes a series of novel proximity relationship learning algorithms to automatically reconstruct urban data in a graph database.
Using the Fragstat software, some key indices were selected to characterize the landscape mosaic with reference to patch size, patch shape, proximity relationship and edge configuration.
We experimentally evaluate the proposed approach, and demonstrate that the gray distance is much better than the Minkowski distance at both capturing the proximity relationship (or nearness) of two instances and dealing with mixed attributes.
Yet, CCs are closer to the oocyte and maintain a proximity relationship via transzonal processes and gap junctions with the oocyte, providing nutrients, maturation-enabling factors, and an optimal microenvironment to ensure successful maturation and further developmental competence [ 2, 3].
This graph is log-log and indicates that (at least for distances under 20 km) the risk-proximity relationship varies approximately with 1/r2 as the slope of the line is about minus 2. In other words, the tritium concentration/distance relationship resembles the risk/distance relationship observed in the KiKK study.
