Assessing the effects of non-pharmaceutical interventions on SARS-CoV-2 transmission in Belgium by means of an extended SEIQRD model and public mobility data

open access: yesEpidemics, 2021
We present a compartmental extended SEIQRD metapopulation model for SARS-CoV-2 spread in Belgium. We demonstrate the robustness of the calibration procedure by calibrating the model using incrementally larger datasets and dissect the model results by ...

GROUP CLASSIFICATION FOR A GENERAL NONLINEAR MODEL OF OPTIONS PRICING

open access: yesUral Mathematical Journal, 2016
We consider a family of equations with two free functional parameters containing the classical Black–Scholes model, Schönbucher–Wilmott model, Sircar–Papanicolaou equation for option pricing as partial cases.

Global solution to the compressible non-isothermal nematic liquid crystal equations with constant heat conductivity and vacuum

open access: yesAdvances in Difference Equations, 2021
This paper considers the initial-boundary value problem of the one-dimensional full compressible nematic liquid crystal flow problem. The initial density is allowed to touch vacuum, and the viscous and heat conductivity coefficients are kept to be ...

Analysis of spatio-temporal fungal growth dynamics under different environmental conditions

open access: yesIMA Fungus, 2019
Traditionally, fungal growth dynamics were assessed manually, limiting the research to a few environmental conditions and/or fungal species. Fortunately, more automated ways of measurement are gaining momentum due to the availability of cheap imaging and

Cold-Start Problems in Data-Driven Prediction of Drug–Drug Interaction Effects

open access: yesPharmaceuticals, 2021
Combining drugs, a phenomenon often referred to as polypharmacy, can induce additional adverse effects. The identification of adverse combinations is a key task in pharmacovigilance.

Mathematical Analysis of a Generalized Chiral Quark Soliton Model [PDF]

open access: yes, 2006
A generalized version of the so-called chiral quark soliton model (CQSM) in nuclear physics is introduced. The Hamiltonian of the generalized CQSM is given by a Dirac type operator with a mass term being an operator-valued function.

Mathematical analysis of the photoelectric effect

open access: yes, 2001
We study the photoelectric effect on the example of a simplified model of an atom with a single bound state, coupled to the quantized electromagnetic field.
