Epidemiology and Characteristics of SARS-CoV-2 Variants of Concern: The Impacts of the Spike Mutations

open access: yesMicroorganisms, 2022
SARS-CoV-2 expresses on its surface the Spike protein responsible for binding with the ACE2 receptor and which carries the majority of immunodominant epitopes.

Predicting the size and probability of epidemics in a population with heterogeneous infectiousness and susceptibility [PDF]

open access: yes, 2007
We analytically address disease outbreaks in large, random networks with heterogeneous infectivity and susceptibility. The transmissibility $T_{uv}$ (the probability that infection of $u$ causes infection of $v$) depends on the infectivity of $u$ and the

Imperfect spreading on temporal networks

open access: yes, 2015
We study spreading on networks where the contact dynamics between the nodes is governed by a random process and where the inter-contact time distribution may differ from the exponential. We consider a process of imperfect spreading, where transmission is

Epidemic model with isolation in multilayer networks [PDF]

open access: yes, 2015
The Susceptible-Infected-Recovered (SIR) model has successfully mimicked the propagation of such airborne diseases as influenza A (H1N1). Although the SIR model has recently been studied in a multilayer networks configuration, in almost all the research ...

Transmissibility and transmission of respiratory viruses [PDF]

open access: yesNature Reviews Microbiology, 2021
Human respiratory virus infections lead to a spectrum of respiratory symptoms and disease severity, contributing to substantial morbidity, mortality and economic losses worldwide, as seen in the COVID-19 pandemic. Belonging to diverse families, respiratory viruses differ in how easy they spread (transmissibility) and the mechanism (modes) of ...

The transmissibility of vibration isolators with a nonlinear anti-symmetric damping characteristic [PDF]

open access: yes, 2008
In the present study, the concept of the Output Frequency Response Function (OFRF), recently proposed by the authors, is applied to theoretically investigate the transmissibility of SDOF passive vibration isolators with a nonlinear anti-symmetric damping

One-way trip: Influenza virus' adaptation to gallinaceous poultry may limit its pandemic potential [PDF]

open access: yes, 2014
We hypothesise that some influenza virus adaptations to poultry may explain why the barrier for human-to-human transmission is not easily overcome once the virus has crossed from wild birds to chickens.

Natural Frequency Transmissibility for Detection of Cracks in Horizontal Axis Wind Turbine Blades

open access: yesSensors
Defects on horizontal axis wind turbine blades are difficult to identify and monitor with conventional forms of non-destructive examination due to the blade’s large size and limited accessibility during continuous operation.

Fractional-order susceptible-infected model: definition and applications to the study of COVID-19 main protease [PDF]

open access: yes, 2020
We propose a model for the transmission of perturbations across the amino acids of a protein represented as an interaction network. The dynamics consists of a Susceptible-Infected (SI) model based on the Caputo fractional-order derivative.

Comparative Pathogenicity and Transmissibility of the H7N9 Highly Pathogenic Avian Influenza Virus and the H7N9 Low Pathogenic Avian Influenza Virus in Chickens

open access: yesViruses, 2019
There were five outbreaks of H7N9 influenza virus in humans in China since it emerged in 2013, infecting >1000 people. The H7N9 low pathogenic influenza virus was inserted into four amino acids in the HA protein cleavage site to mutate into the H7N9 ...
