Homogeneity vs. Adjacency: generalising some graph decomposition algorithms [PDF]

open access: yesGraph-Theoretic Concepts in Computer Science Springer (Ed.) (22/06/2006) 278-288, 2006
In this paper, a new general decomposition theory inspired from modular graph decomposition is presented. Our main result shows that, within this general theory, most of the nice algorithmic tools developed for modular decomposition are still efficient.

Does leaf litter from invasive plants contribute the same support of a stream ecosystem function as native vegetation?

open access: yesEcosphere, 2017
Riparian habitats are highly susceptible to invasion and the spread of non‐native plants. Many freshwater organisms and processes are dependent on allochthonous subsidies, and thus, riparian invasions are often associated with changes in aquatic ...

Different resistance to UV-B radiation of extracellular polymeric substances of two cyanobacteria from contrasting habitats

open access: yesFrontiers in Microbiology, 2016
The effects of UV-B radiation (UVBR) on photosynthetic activity (Fv/Fm) of aquatic Synechocystis sp. and desert Chroococcus minutus and effects on composition and fluorescence property of extracellular polymeric substances (EPS) from Synechocystis sp ...

Tracing 33P-labelled organic phosphorus compounds in two soils: New insights into decomposition dynamics and direct use by microbes

open access: yesFrontiers in Soil Science, 2023
IntroductionOrganic phosphorus (Po) compounds constitute an important pool in soil P cycling, but their decomposition dynamics are poorly understood. Further, it has never been directly tested whether low molecular weight Po compounds are taken up by ...

Plant Litter Type Dictates Microbial Communities Responsible for Greenhouse Gas Production in Amended Lake Sediments

open access: yesFrontiers in Microbiology, 2018
The microbial communities of lake sediments play key roles in carbon cycling, linking lakes to their surrounding landscapes and to the global climate system as incubators of terrestrial organic matter and emitters of greenhouse gasses, respectively. Here,

Triangular Decomposition of Matrices in a Domain [PDF]

open access: yesComputer Algebra in Scientific Computing. LNCS 9301, Springer, Switzerland, 2015, P.290-304, 2017
Deterministic recursive algorithms for the computation of matrix triangular decompositions with permutations like LU and Bruhat decomposition are presented for the case of commutative domains. This decomposition can be considered as a generalization of LU and Bruhat decompositions, because they both may be easily obtained from this triangular ...

The Role of Plant Litter in Driving Plant-Soil Feedbacks

open access: yesFrontiers in Environmental Science, 2019
Most studies focusing on plant-soil feedbacks (PSFs) have considered direct interactions between plants, abiotic conditions (e. g., soil nutrients) and rhizosphere communities (e.g., pathogens, mutualists). However, few studies have addressed the role of

IoT Capabilities Composition and Decomposition: A Systematic Review

open access: yesIEEE Access, 2023
As billions of IoT devices join the Internet, researchers and innovators increasingly explore IoT capabilities achieved via service composition or reuse of existing capabilities via service decomposition.

Effects of Eucalyptus species plantations and crop land on selected soil properties

open access: yesGeology, Ecology, and Landscapes, 2020
The physical and chemical properties of soil are strongly influenced by type of land use system implemented. Eucalyptus is a group of tree species, which is native to Australia but widely grown throughout the world.

Mesoprimary decomposition of binomial submodules [PDF]

open access: yesJournal of Algebra 480 (2017), 59-78, 2015
Recent results of Kahle and Miller give a method of constructing primary decompositions of binomial ideals by first constructing "mesoprimary decompositions" determined by their underlying monoid congruences. These mesoprimary decompositions are highly combinatorial in nature, and are designed to parallel standard primary decomposition over Noetherean ...
