MODEL MATEMATIKA PENYEBARAN PENYAKIT PULMONARY TUBERCULOSIS DENGAN PENGGUNAAN MASKER MEDIS

open access: yesBarekeng, 2020
This research developed a model of tuberculosis disease spread using the SIR model with addition of the medical mask usage factor. First, we create a diagram of the tuberculosis disease spread compartment through contact between individuals with medical ...

Effects of Demographic and Weather Parameters on COVID-19 Basic Reproduction Number [PDF]

open access: yesFrontiers in Ecology and Evolution, 2020
It is hard to overstate the importance of a timely prediction of the COVID-19 pandemic progression. Yet, this is not possible without a comprehensive understanding of environmental factors that may affect the infection transmissibility.

Experimental pig-to-pig transmission dynamics for African swine fever virus, Georgia 2007/1 strain [PDF]

open access: yes, 2015
African swine fever virus (ASFV) continues to cause outbreaks in domestic pigs and wild boar in Eastern European countries. To gain insights into its transmission dynamics, we estimated the pig-to-pig basic reproduction number (R 0) for the Georgia 2007 ...

On the existence of a nontrivial equilibrium in relation to the basic reproductive number [PDF]

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2017
AbstractEquilibrium analysis in autonomous evolutionary models is of central importance for developing long term treatments. This task typically includes checks on the existence and stability of some equilibria. Prior to touching on the stability, one often attempts to determine the existence where the basic reproductive numberℛ0plays a critical role ...

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

Graphs with specified degree distributions, simple epidemics and local vaccination strategies

open access: yes, 2007
Consider a random graph, having a pre-specified degree distribution F but other than that being uniformly distributed, describing the social structure (friendship) in a large community. Suppose one individual in the community is externally infected by an

The linear stability and basic reproduction numbers for autonomous FDEs

open access: yesDiscrete and Continuous Dynamical Systems - S, 2023
In this paper, we first prove the stability equivalence between a linear autonomous and cooperative functional differential equation (FDE) and its associated autonomous and cooperative system without time delay. Then we present the theory of basic reproduction number $\mathcal{R}_0$ for general autonomous FDEs.

The Basic Reproductive Number for Disease Systems with Multiple Coupled Heterogeneities [PDF]

open access: yesMathematical Biosciences, 2017
AbstractIn mathematical epidemiology, a well-known formula describes the impact of heterogeneity on the basic reproductive number,R0, for situations in which transmission is separable and for which there is one source of variation in susceptibility and one source of variation in infectiousness.

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

Collocation of Next-Generation Operators for Computing the Basic Reproduction Number of Structured Populations

open access: yesJournal of Scientific Computing, 2020
We contribute a full analysis of theoretical and numerical aspects of the collocation approach recently proposed by some of the authors to compute the basic reproduction number of structured population dynamics as spectral radius of certain infinite ...
