Degree resistance distance of unicyclic graphs [PDF]

Transactions on Combinatorics, 2012
Let G be a connected graph with vertex set V(G). The degree resistance distance of G is defined as the sum over all pairs of vertices of the terms [d(u)+d(v)] R(u,v), where d(u) is the degree of vertex u, and R(u,v) denotes the resistance distance ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Novel Face Index for Benzenoid Hydrocarbons

Mathematics, 2020
A novel topological index, the face index ( F I ), is proposed in this paper. For a molecular graph G, face index is defined as F I ( G ) = ∑ f ∈ F ( G ) d ( f ) = ∑ v ∼ f , f ∈ F ( G ) d ( v ...

Limit distributions of vertex degrees in a conditional configuration graph

Proceedings of the Karelian Research Centre of the Russian Academy of Sciences, 2018
The configuration graph where vertex degrees are independent identically distributed random variables is often used for  modeling of complex networks such as the Internet. We consider a random graph consisting of   N vertices. The random variables η1,….,ηN are  equal to the degrees of vertices with the numbers 1,… ,N The probability  P{ηi=k},  i=1,…, N,

Functional Connectivity Linked to Cognitive Recovery After Minor Stroke

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Patients with minor stroke exhibit slowed processing speed and generalized alterations in functional connectivity involving frontoparietal cortex (FPC). The pattern of connectivity evolves over time. In this study, we examine the relationship of functional connectivity patterns to cognitive performance, to determine ...

ORDERING CATACONDENSED HEXAGONAL SYSTEMS WITH RESPECT TO VDB TOPOLOGICAL INDICES

Revista de Matemática: Teoría y Aplicaciones, 2017
In this paper we give a complete description of the ordering relations in the set of catacondensed hexagonal systems, with respect to a vertex-degree-based topological index. As a consequence, extremal values of vertex-degree-based topological indices in

Spanning trees in graphs of high minimum degree with a universal vertex II: A tight result

Journal of Graph Theory, 2022
AbstractWe prove that, if is sufficiently large, every graph on vertices that has a universal vertex and minimum degree at least contains each tree with edges as a subgraph. Our result confirms, for large , an important special case of a conjecture by Havet, Reed, Stein, and Wood.

Prognostic Implications of Sleep Architecture for Patients Admitted to the Intensive Care Unit With Status Epilepticus

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Status epilepticus (SE) is associated with significant mortality. Sleep architecture may reflect normal brain function. Impaired sleep architecture is associated with poorer outcomes in numerous conditions. Here we investigate the association of sleep architecture in continuous EEG (cEEG) with survival in SE.

Random graphs with arbitrary degree distributions and their applications

, 2001
Recent work on the structure of social networks and the internet has focussed attention on graphs with distributions of vertex degree that are significantly different from the Poisson degree distributions that have been widely studied in the past.
