Core–periphery models for graphs based on their -hyperbolicity: An example using biological networks

Journal of Algorithms & Computational Technology, 2017
Hyperbolicity is a global property of graphs that measures how close their structures are to trees in terms of their distances. It embeds multiple properties that facilitate solving several problems that found to be hard in the general graph form.

Analysis of Core–Periphery Structure Based on Clustering Aggregation in the NFT Transfer Network

Entropy
With the rise of blockchain technology and the Ethereum platform, non-fungible tokens (NFTs) have emerged as a new class of digital assets. The NFT transfer network exhibits core–periphery structures derived from different partitioning methods, leading ...

Approximation Methods: An Application to the Core-Periphery Model [PDF]

SSRN Electronic Journal, 2002
A feature of new economic geography model is their mathematical intractability. This intractability results from the fact that the functional relationship between the indirect utility differential and the state variable cannot be found explicitly. We illustrate three methods that can be utilized to approximate the unknown function.

Empirical assessment and refinement of corrosion distribution models in the perimeter of corroded steel rebar subjected to chloride ions attack

Case Studies in Construction Materials, 2022
Predicting the volume of corrosion products (CP) and their distribution in the steel rebar periphery will play an essential role in estimating the expansion stresses and, consequently, the behaviour of concrete in extreme environmental circumstances.

Informal Network Integration and MNEs Territorial Embeddedness: Mapping Differences

Estudios Económicos, 2022
This article deals with a theoretical opposition of two similar, but conceptually different spatial models of transborder network cooperation (namely MNEs’ territorial embeddedness and informal network integration) from the aspect of corporate power ...

Reconstructing Mesoscale Network Structures

Complexity, 2019
When facing the problem of reconstructing complex mesoscale network structures, it is generally believed that models encoding the nodes organization into modules must be employed.

Animal Models of Vestibular Evoked Myogenic Potentials: The Past, Present, and Future

Frontiers in Neurology, 2018
Vestibular-evoked myogenic potentials (VEMPs) provide a simple and cost-effective means to assess the patency of vestibular reflexes. VEMP testing constitutes a core screening method in a clinical battery that probes vestibular function.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

The role of density-dependent and -independent processes in spawning habitat selection by salmon in an Arctic riverscape.

PLoS ONE, 2017
Density-dependent (DD) and density-independent (DI) habitat selection is strongly linked to a species' evolutionary history. Determining the relative importance of each is necessary because declining populations are not always the result of altered DI ...

Density-dependent regulation of brook trout population dynamics along a core-periphery distribution gradient in a central Appalachian watershed. [PDF]

PLoS ONE, 2014
Spatial population models predict strong density-dependence and relatively stable population dynamics near the core of a species' distribution with increasing variance and importance of density-independent processes operating towards the population ...
