Classifying Latent Infection States in Complex Networks [PDF]

arXiv, 2014
Algorithms for identifying the infection states of nodes in a network are crucial for understanding and containing infections. Often, however, only a relatively small set of nodes have a known infection state. Moreover, the length of time that each node has been infected is also unknown.

Folding of a Small Helical Protein Using Hydrogen Bonds and Hydrophobicity Forces [PDF]

Proteins Struct. Funct. Genet. 47 (2002) 99-105, 2001
A reduced protein model with five to six atoms per amino acid and five amino acid types is developed and tested on a three-helix-bundle protein, a 46-amino acid fragment from staphylococcal protein A. The model does not rely on the widely used Go approximation where non-native interactions are ignored.

Design of a Protein Potential Energy Landscape by Parameter Optimization [PDF]

arXiv, 2003
We propose an automated protocol for designing the energy landscape of a protein energy function by optimizing its parameters. The parameters are optimized so that not only the global minimum energy conformation becomes native-like, but also the conformations distinct from the native structure have higher energies than those close to the native one ...

Numerical considerations about the SIR epidemic model with infection age [PDF]

arXiv, 2020
We analyse the infection-age-dependent SIR model from a numerical point of view. First, we present an algorithm for calculating the solution the infection-age-structured SIR model without demography of the background host. Second, we examine how and under which conditions, the conventional SIR model (without infection-age) serves as a practical ...

Pan-infection Foundation Framework Enables Multiple Pathogen Prediction [PDF]

arXiv
Host-response-based diagnostics can improve the accuracy of diagnosing bacterial and viral infections, thereby reducing inappropriate antibiotic prescriptions. However, the existing cohorts with limited sample size and coarse infections types are unable to support the exploration of an accurate and generalizable diagnostic model.

SIS Epidemic Spreading with Heterogeneous Infection Rates [PDF]

arXiv, 2015
In this work, we aim to understand the influence of the heterogeneity of infection rates on the Susceptible-Infected-Susceptible (SIS) epidemic spreading. Employing the classic SIS model as the benchmark, we study the influence of the independently identically distributed infection rates on the average fraction of infected nodes in the metastable state.

Infected surfaces of vehicles as possible way of people's infection by bird flu pathogenic culture [PDF]

arXiv, 2007
Possible variant of people's infection by bird flu pathogenic culture in passing of everyday infection is presented in the work: through the contact of open parts of the skin with infected surfaces of the vehicle, that is the sequent of the reused water, which contains all species spectrum of pathogen accumulated on the urban areas, used in process of ...

A new chaotic attractor in a basic multi-strain epidemiological model with temporary cross-immunity [PDF]

arXiv, 2007
An epidemic multi-strain model with temporary cross-immunity shows chaos, even in a previously unexpected parameter region. Especially dengue fever models with strong enhanced infectivity on secondary infection have previously shown deterministic chaos motivated by experimental findings of antibody-dependent-enhancement (ADE). Including temporary cross-

Network infection source identification under the SIRI model [PDF]

arXiv, 2014
We study the problem of identifying a single infection source in a network under the susceptible-infected-recovered-infected (SIRI) model. We describe the infection model via a state-space model, and utilizing a state propagation approach, we derive an algorithm known as the heterogeneous infection spreading source (HISS) estimator, to infer the ...
