• A simulation study to assess the epidemiological impact of pneumonia transmission dynamics in high-risk populations 

  Chukwu, C.W.; Tchoumi, Stephane Y.; Diagne, M.L. (Elsevier, 2024-03)

  The term “high-risk population” refers to individuals with an increased likelihood of contracting a severe illness or disease due to factors such as age, underlying medical conditions, pregnancy, geographical location, or ...
• Dispersion-preserving implicit-explicit numerical methods for reactive flow models 

  Amikiya, Emmanuel Adoliwine; Banda, M.K. (Mapundi) (World Scientific Publishing, 2024-04)

  Chemical reactions occur everywhere in both natural and artificial systems. Some of the reactions occur during the flow of a fluid (such a process is referred to as a reactive flow). Given the hazardous nature of some ...
• A two-strain avian–human influenza model with environmental transmission : stability analysis and optimal control strategies 

  Tadmon, Calvin; Feukouo Fossi, Arnaud; Tsanou, Berge (Elsevier, 2024-06)

  On the basis of the WHO legitimated fear that there will be an avian influenza virus strain capable of mutating once it reaches the human population and sustains human-to-human transmissions, we formulate an hypothetical ...
• On the binary codes of length 552 which admit the simple group Co3 as a transitive permutation group 

  Knapp, Wolfgang D.; Rodrigues, Bernardo G. (Taylor and Francis, 2023)

  In this this paper all binary codes of length 552 which admit the sporadic simple group Co3 as an imprimitive transitive permutation group are determined. Our aim is to understand the results also by using theoretical ...

• A note on the fixed point theorem of F-contraction mappings in rectangular M-metric space 

  Abbas, Mujahid; Anjum, Rizwan; Anwar, Rabia (Universidad Politécnica de Valencia, 2023-03)

  In this note, we show that the main result (Theorem 3.2) due to Asim et al. (Appl. Gen. Topol., 23(2), 363-376 (2022) https://doi.org/10.4995/agt.2022.17418) is still valid if we remove the assumption of continuity of ...
• Spatial spread of infectious diseases with conditional vector preferences 

  Hamelin, Frederic M.; Hilker, Frank M.; Dumont, Yves (Springer, 2023-08)

  We explore the spatial spread of vector-borne infections with conditional vector preferences, meaning that vectors do not visit hosts at random. Vectors may be differentially attracted toward infected and uninfected hosts ...

• Laplace transform-homotopy perturbation method for fractional time diffusive predator–prey models in ecology 

  Owolabi, Kolade M.; Pindza, Edson; Karaagac, Berat; Oguz, Gulay (Elsevier, 2024-03)

  In this paper, we consider some reaction–diffusion systems arising from two-component predator–prey models with various kinetics ranging from prey-dependent, ratio-dependent functional responses and subdiffusion. The goal ...
• Pricing two-asset rainbow options with the fast Fourier transform 

  Levendis, Alexis; Mare, Eben (South African Statistical Association (SASA), 2023)

  In this paper, we present a numerical method based on the fast Fourier transform (FFT) to price call options on the minimum of two assets, otherwise known as two-asset rainbow options. We consider two stochastic processes ...
• Semilinear De Morgan monoids and epimorphisms 

  Wannenburg, Johann Joubert; Raftery, James G. (Springer, 2024-01)

  A representation theorem is proved for De Morgan monoids that are (i) semilinear, i.e., subdirect products of totally ordered algebras, and (ii) negatively generated, i.e., generated by lower bounds of the neutral element. ...
• A surjective summation operator with no Lipschitz right inverse 

  Laustsen, Niels Jakob; Messerschmidt, Miek; Wortel, Marten (American Mathematical Society, 2024-01)

  We show that there exists a Banach space X which contains closed subspaces Y and Z with Y+Z=X such that the associated surjective summation operator Σ: Y×Z→X defined by Σ(y,z)= y+z for y∈Y and z∈Z has no Lipschitz right inverse.
• A domain-dependent stability analysis of reaction–diffusion systems with linear cross-diffusion on circular domains 

  Yigit, Gulsemay; Sarfaraz, Wakil; Barreira, Raquel; Madzvamuse, Anotida (Elsevier, 2024-06)

  In this study, we present theoretical considerations of, and analyse, the effects of circular geometry on the stability analysis of semi-linear parabolic PDEs of reaction–diffusion type with linear cross-diffusion for a ...
• Efficient numerical techniques for computing the Riesz fractional-order reaction-diffusion models arising in biology 

  Alqhtani, Manal; Owolabi, Kolade M.; Saad, Khaled M.; Pindza, Edson (Elsevier, 2022-08)

  In this work, the solution of Riesz space fractional partial differential equations of parabolic type is considered. Since fractional-in-space operators have been applied to model anomalous diffusion or dispersion problems ...
• Sex-structured model of Wolbachia invasion and design of sex-biased release strategies in Aedes spp mosquitoes populations 

  Bliman, Pierre-Alexandre; Dumont, Yves; Escobar-Lasso, Oscar Eduardo; Martinez-Romero, Hector J.; Vasilieva, Olga (Elsevier, 2023-07)

  Laboratory experiments as well as some field essays have revealed that the intracellular bacterium Wolbachia, deliberately introduced in Aedes spp female mosquitoes, drastically reduces their vector competence for dengue ...
• Existence of travelling waves in a spatial model of bacteria quiescence 

  Chapwanya, Michael; Dumani, Phindile (Royal Society, 2023-10)

  This work presents a reaction–diffusion model that captures the spatio-temporal evolution of a bacterial colony and takes into account the quiescent stage. Using the theory of monotone wavefronts for cooperative and partially ...
