Fireworks explosion boosted Harris Hawks optimization for numerical optimization: Case of classifying the severity of COVID-19 [PDF]

open access: yesFrontiers in Neuroinformatics, 2023
Harris Hawks optimization (HHO) is a swarm optimization approach capable of handling a broad range of optimization problems. HHO, on the other hand, is commonly plagued by inadequate exploitation and a sluggish rate of convergence for certain numerical ...

Modification of the double direction approach for solving systems of nonlinear equations with application to Chandrasekhar’s Integral equation [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2022
This study aims to present an accelerated derivative-free method for solving systems of nonlinear equations using a double direction approach. The approach approximates the Jacobian using a suitably formed diag-onal matrix by applying the acceleration ...

On two symmetric Dai-Kou type schemes for constrained monotone equations with image recovery application

open access: yesEURO Journal on Computational Optimization, 2023
The Dai-Kou method Dai and Kou (2013), [12] is efficient for solving unconstrained optimization problems. However, its modified variants are quite rare for constrained nonlinear monotone equations.

Double direction three-term spectral conjugate gradient method for solving symmetric nonlinear equations

open access: yesResults in Control and Optimization, 2022
We propose a new three-term spectral conjugate gradient method via double direction approach by considering the first direction to be the one proposed by Halilu and Waziri (2018) and the other obtained by extending the direction proposed by Birgin and ...

Chiral flows can induce neck formation in viscoelastic surfaces

open access: yesNew Journal of Physics, 2023
The cell cortex is an active viscoelastic self-deforming sheet at the periphery of animal cells. It constricts animal cells during cell division. For some egg cells, the actomyosin cortex was shown to exhibit counter-rotating chiral flows along the axis ...

Pulsatory patterns in active viscoelastic fluids with distinct relaxation time scales

open access: yesNew Journal of Physics, 2023
Developing tissues need to pattern themselves in space and time. A prevalent mechanism to achieve this are pulsatile active stresses generated by the actin cytoskeleton.

On the role of mechanosensitive binding dynamics in the pattern formation of active surfaces

open access: yesNew Journal of Physics, 2022
The actin cortex of an animal cell is a thin polymeric layer attached to the inner side of the plasma membrane. It plays a key role in shape regulation and pattern formation on the cellular and tissue scale and, in particular, generates the contractile ...
