Mathematical modeling and analysis for the co-infection of COVID-19 and tuberculosis

Heliyon, 2022
We developed a TB-COVID-19 co-infection epidemic model using a non-linear dynamical system by subdividing the human population into seven compartments. The biological well-posedness of the formulated mathematical model was studied via proving properties ...

Study of an SIQR model with optimal control techniques: A mathematical approach

Results in Control and Optimization, 2023
In this article, a SIQR deterministic model with a non-linear incidence function for an infectious disease is formulated and analyzed. The well-posedness of the model is ensured with the help of the non-negativity and boundedness of the solution of the ...

Dictionary‐based weak‐form training for noise‐robust series hybrid models with multiplicative unknowns

AIChE Journal, EarlyView.
ABSTRACT Hybrid modeling combines first‐principles equations with a data‐driven subcomponent. Training for the data‐driven part is sensitive to measurement noise when training targets are constructed using pointwise time derivatives. Beyond differentiation errors, hybrid models involve solving an inverse problem to estimate the data‐driven term, which ...

Transcritical bifurcation in a new fractional influenza-type model with dual general incidences

Scientific African
We study a fractional influenza-type epidemic model with Caputo derivative of order ϑ∈(0,1], dual incidence kernels acting on susceptible and vaccinated individuals, vaccination with imperfect protection, waning immunity, isolation, and symptomatic ...

Qualitative and sensitivity analysis on simple epidemic model (SIR-MODEL): ensuring well-posedness and stability

Journal of Statistical Sciences and Computational Intelligence
This study investigates the dynamics of infectious disease transmission using an SIR (Susceptible-Infected-Recovered) model. We examine the model’s positivity, equilibrium points, basic reproduction number using the next generation matrix method, and sensitivity to key parameters using the sensitivity index method.

Intrinsically Design‐Rule‐Compliant Nanophotonic Inverse Design via Learned Generative Manifolds

Laser &Photonics Reviews, EarlyView.
A generative reparameterization framework for nanophotonic inverse design is introduced, restricting optimization to a learned manifold of design‐rule‐compliant geometries. Unlike conventional penalty‐based approaches, fabrication constraints are encoded intrinsically within the design representation.
