Epidemic spreading on weighted contact networks [PDF]

2007 2nd Bio-Inspired Models of Network, Information and Computing Systems, 2007
The study of epidemics is a crucial issue to several areas. An epidemic can have devastating economic and social consequences. A single crop disease in Kansas could destroy the yearly income of many farmers. Previous work using graph theory has determined a universal epidemic threshold found in the graph topology for a binary contact network in the ...

Optimal contact process on complex networks [PDF]

Physical Review E, 2008
Contact processes on complex networks are a recent subject of study in nonequilibrium statistical physics and they are also important to applied fields such as epidemiology and computer and communication networks. A basic issue concerns finding an optimal strategy for spreading. We provide a universal strategy that, when a basic quantity in the contact

PyPCN: protein contact networks in PyMOL

Bioinformatics, 2023
Abstract Motivation Protein contact networks (PCNs) represent the 3D structure of a protein using network formalism. Inter-residue contacts are described as binary adjacency matrices, which are derived from the graph representation of residues (as α-carbons, β-carbons or centroids) and Euclidean ...

Comparison of contact patterns relevant for transmission of respiratory pathogens in Thailand and the Netherlands using respondent-driven sampling

, 2014
Understanding infection dynamics of respiratory diseases requires the identification and quantification of behavioural, social and environmental factors that permit the transmission of these infections between humans.

Asymmetrically interacting spreading dynamics on complex layered networks [PDF]

, 2014
The spread of disease through a physical-contact network and the spread of information about the disease on a communication network are two intimately related dynamical processes.

Predicting epidemics on directed contact networks [PDF]

Journal of Theoretical Biology, 2006
Contact network epidemiology is an approach to modeling the spread of infectious diseases that explicitly considers patterns of person-to-person contacts within a community. Contacts can be asymmetric, with a person more likely to infect one of their contacts than to become infected by that contact.

Prediction of hospital-onset COVID-19 using networks of patient contact: an observational study

International Journal of Infectious Diseases, 2022
Purpose: Predicting healthcare-acquired infections (HAIs) has the potential to revolutionise the prevention and control of transmissible infections.

Spatial analyses of wildlife contact networks [PDF]

Journal of The Royal Society Interface, 2015
Datasets from which wildlife contact networks of epidemiological importance can be inferred are becoming increasingly common. A largely unexplored facet of these data is finding evidence of spatial constraints on who has contact with whom, despite theoretical epidemiologists having long realized spatial constraints can play a critical role in ...

Determination of long-term permissible currents in wires of power supply systems of railways

Вестник Научно-исследовательского института железнодорожного транспорта, 2019
In the standard for contact wires made from copper and its alloys, the values of long-term permissible temperatures have significantly decreased. This requires recalculation of previously valid values of long-term permissible currents. Authors considered

Contact Adaption during Epidemics: A Multilayer Network Formulation Approach

, 2018
People change their physical contacts as a preventive response to infectious disease propagations. Yet, only a few mathematical models consider the coupled dynamics of the disease propagation and the contact adaptation process.
