A hexahedral mesh connectivity compression with vertex degrees
Computer-Aided Design, 2008 This paper introduces a new algorithm for the compression of manifold hexahedral meshes topology, using vertex degree. The topology compression consists of two parts-the mesh's boundary consisting of quadrilaterals is compressed first, and then the hexahedra are processed by the help of six commands.

Feedback vertex sets on tree convex bipartite graphs [PDF]
, 2012 A feedback vertex set in a graph is a subset of vertices, such that the complement of this subset induces a forest. Finding a minimum feedback vertex set (FVS) is -complete on bipartite graphs, but tractable on chordal bipartite graphs. A bipartite graph

A Parameterized Algorithm for Bounded-Degree Vertex Deletion [PDF]
, 2016 The $d$-bounded-degree vertex deletion problem, to delete at most $k$ vertices in a given graph to make the maximum degree of the remaining graph at most $d$, finds applications in computational biology, social network analysis and some others. It can be regarded as a special case of the $(d+2)$-hitting set problem and generates the famous vertex cover

Vertex Degrees and Isomorphic Properties in Complement of an m-Polar Fuzzy Graph
Advances in Fuzzy Systems, 2017 Computational intelligence and computer science rely on graph theory to solve combinatorial problems. Normal product and tensor product of an m-polar fuzzy graph have been introduced in this article.

On leap Zagreb indices of graphs
Communications in Combinatorics and Optimization, 2017 The first and second Zagreb indices of a graph are equal, respectively, to the sum of squares of the vertex degrees, and the sum of the products of the degrees of pairs of adjacent vertices.

Iron‐Mediated Release of Aged Dissolved Organic Carbon From Waterlogged Peatland Under Warming
Advanced Science, EarlyView.This study conducts a five‐year in situ warming experiment in high‐altitude peatlands to examine dissolved organic carbon (DOC) release. The study shows that warming promotes the release of plant‐derived modern DOC in drained peatlands, but amplifies aquatic export of century‐old DOC from waterlogged peatlands via Fe‐mediated DOC mobilization—a ...

Joint Vertex Degrees in an Inhomogeneous Random Graph Model [PDF]
, 2009 In a random graph, counts for the number of vertices with given degrees will typically be dependent. We show via a multivariate normal and a Poisson process approximation that, for graphs which have independent edges, with a possibly inhomogeneous ...
