Leaf litter decomposition rates: influence of successional age, topography and microenvironment on six dominant tree species in a tropical dry forest

open access: yesFrontiers in Forests and Global Change, 2023
Litter decomposition is a central process in forest ecosystems because of its role in carbon and nutrient cycling and maintaining soil fertility.

TD-H2H: Shortest Path Query on Time-Dependent Graphs [PDF]

open access: yesJisuanji kexue yu tansuo, 2023
A shortest path query on road networks is a fundamental problem, which has been studied widely. Existing studies usually model road networks as a static graph and query the path with the shortest distance between given vertices.

Decomposition dynamics of coarse woody debris of three important central European tree species

open access: yesForest Ecosystems, 2015
Background Coarse woody debris (CWD) is an important element of forest structure that needs to be considered when managing forests for biodiversity, carbon storage or bioenergy. To manage it effectively, dynamics of CWD decomposition should be known.

Ordered Tree Decomposition for HRG Rule Extraction [PDF]

open access: yesComputational Linguistics, 2019
We present algorithms for extracting Hyperedge Replacement Grammar (HRG) rules from a graph along with a vertex order. Our algorithms are based on finding a tree decomposition of smallest width, relative to the vertex order, and then extracting one rule ...

Effects of light intensity on litter decomposition in a subtropical region

open access: yesEcosphere, 2017
Sunlight, as a main driver of terrestrial ecosystem process, not only runs the synthesis, but also the decomposition. In nature, soil surface might be exposed to different light intensities, but the decomposition as affected by light intensity remains ...

Soil carbon dynamics are linked to tree species growth strategy in a naturally regenerating tropical forest

open access: yesFrontiers in Forests and Global Change, 2023
Secondary tropical forests are increasingly important for their role in the global carbon (C) balance as they can rapidly accumulate aboveground biomass C during regrowth.

Tree-Structured Shading Decomposition

open access: yes2023 IEEE/CVF International Conference on Computer Vision (ICCV), 2023
We study inferring a tree-structured representation from a single image for object shading. Prior work typically uses the parametric or measured representation to model shading, which is neither interpretable nor easily editable. We propose using the shade tree representation, which combines basic shading nodes and compositing methods to factorize ...

HD-Tree: An Efficient High-Dimensional Virtual Index Structure Using a Half Decomposition Strategy

open access: yesAlgorithms, 2020
To manage multidimensional point data more efficiently, this paper presents an improvement, called HD-tree, of a previous indexing method, called D-tree.
