Borehole nuclear magnetic resonance as a promising 3D mapping tool in peatland studies

open access: yesGeoderma
The potential and limitations of the Borehole Nuclear Magnetic Resonance (BNMR) technique as an in situ measurement for peatland soil characterization was tested in 163 boreholes at four selected peatlands in Denmark.

Creating real network with expected degree distribution: A statistical simulation [PDF]

open access: yesNetwork Biology, 2012
The degree distribution of known networks is one of the focuses in network analysis. However, its inverse problem, i.e., to create network from known degree distribution has not yet been reported.

Structure analysis of growing network based on partial differential equations

open access: yesJournal of Hebei University of Science and Technology, 2016
The topological structure is one of the most important contents in the complex network research. Therein the node degree and the degree distribution are the most basic characteristic quantities to describe topological structure. In order to calculate the

Degree-distribution Stability of Evolving Networks

open access: yes, 2009
In this paper, we study a class of stochastic processes, called evolving network Markov chains, in evolving networks. Our approach is to transform the degree distribution problem of an evolving network to a corresponding problem of evolving network Markov chains.

The Influence of Branching Architecture on Scission in Modeling Free-Radical Polymerization with Long Chain Branching and Scission

open access: yesCHIMIA, 2001
In modeling molecular weight (MWD) and degree of branching (DBD) distribution for radical polymerization systems, assumptions have to be made concerning the length and the number of branches of fragments from scission reactions. The linear-chain

Degrees of join-distributivity via Bruns–Lakser towers

open access: yesIndagationes Mathematicae
We utilize the Bruns-Lakser completion to introduce Bruns-Lakser towers of a meet-semilattice. This machinery enables us to develop various hierarchies inside the class of bounded distributive lattices, which measure $κ$-degrees of distributivity of bounded distributive lattices and their Dedekind-MacNeille completions. We also use Priestley duality to
