Analyzing the Behavior of Neuronal Pathways in Alzheimer's Disease Using Petri Net Modeling Approach [PDF]

open access: yesFrontiers in Neuroinformatics, 2018
Alzheimer's Disease (AD) is the most common neuro-degenerative disorder in the elderly that leads to dementia. The hallmark of AD is senile lesions made by abnormal aggregation of amyloid beta in extracellular space of brain.

Proactive Control of Petri Disease of Grapevine Through Treatment of Propagation Material [PDF]

open access: yesPlant Disease, 2004
Petri disease is a vascular disease associated with decline and dieback of young grapevines. A major means of spread of the causal organisms, Phaeomoniella chlamydospora and Phaeoacremonium spp., is via infected propagation material. Since no curative control measures are known, proactive measures must be taken in grapevine nurseries to manage this ...

Manganese Oxidation in Petri Disease Fungi as a Novel Taxonomic Character

open access: yesPhytopathologia Mediterranea, 2006
Manganese (Mn) oxidation was evaluated for Petri disease fungi by using potato dextrose agar (PDA) amended with Mn sulfate. Phaeomoniella chlamydospora showed reduced growth on PDA amended with 3000 ppm Mn sulfate and exhibited no growth at higher ...

Modelling epistasis in genetic disease using Petri nets, evolutionary computation and frequent itemset mining [PDF]

open access: yesExpert Systems With Applications, 2011
Petri nets are useful for mathematically modelling disease-causing genetic epistasis. A Petri net model of an interaction has the potential to lead to biological insight into the cause of a genetic disease. However, defining a Petri net by hand for a particular interaction is extremely difficult because of the sheer complexity of the problem and ...

A Numerical Comparison of Petri Net and Ordinary Differential Equation SIR Component Models [PDF]

open access: yesIEEE Access
Petri nets are an increasingly used modeling framework for the spread of disease across populations or within an individual. For example, the Susceptible-Infectious-Recovered (SIR) compartment model is foundational for population epidemiological modeling
