Uncertainty and Sensitivity Analysis of Solute Contaminant Transport Simulation in Groundwater (Case Study: Qazvin Plain) [PDF]

open access: yesآب و فاضلاب, 2021
Groundwater contaminant transport modeling is a useful tool for identifying how pollutants fate and transport in porous aquifer environments. These models include several parameters, which are often estimated based on personal judgment or in the best ...

Dynamics of a two-group structured malaria transmission model

open access: yesInformatics in Medicine Unlocked, 2022
Malaria is an infectious vector-borne disease of global public concern, with high morbidity and mortality in children less than 5 years old. We propose a two-group malaria model structured by age with the SEISdynamic in individuals aged below 5 years old,

Local and Global Distinguishability in Quantum Interferometry [PDF]

open access: yes, 2006
A statistical distinguishability based on relative entropy characterises the fitness of quantum states for phase estimation. This criterion is employed in the context of a Mach-Zehnder interferometer and used to interpolate between two regimes, of local ...

Rash impulsiveness and negative mood, but not alexithymia or reward sensitivity, differentiate young to middle-aged chronic daily smokers from never-smokers [PDF]

open access: yes, 2017
Given the well-established associations of the personality traits alexithymia, impulsivity, and reward sensitivity with problematic use of a variety of substances, including alcohol and cannabis, the present study sought to determine whether daily ...

Model simplification of signal transduction pathway networks via a hybrid inference strategy [PDF]

open access: yes, 2008
A full-scale mathematical model of cellular networks normally involves a large number of variables and parameters. How to effectively develop manageable and reliable models is crucial for effective computation, analysis and design of such systems.

Global Dynamics in an Alcoholism Epidemic Model with Saturation Incidence Rate and Two Distributed Delays

open access: yesMathematics, 2023
In this study, considering the delays for a susceptible individual becoming an alcoholic and the relapse of a recovered individual back into being an alcoholic, we formulate an epidemic model for alcoholism with distributed delays and relapse.
