Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

FEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

On Fuzzy differential equation

Journal of Al-Qadisiyah for Computer Science and Mathematics, 2019
In this paper, we introduce a hybrid method to use fuzzy differential equation, and Genetic Turing Machine developed for solving nth order fuzzy differential equation under Seikkala differentiability concept [14]. The Errors between the exact solutions and the approximate solutions were computed by fitness function and the Genetic Turing Machine ...

Fuzzy modelling on the depletion of forest biomass and forest-dependent wildlife population

Franklin Open, 2023
This paper presents a system of non-linear differential equations describing the depletion of forest biomass and forest-dependent wildlife population caused by human population and its associated activities. The model incorporates the imprecise nature of

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.

ON FUZZY STOCHASTIC DIFFERENTIAL EQUATIONS

Journal of the Korean Mathematical Society, 2005
The author considers a fuzzy stochastic differential equation containing a fuzzy valued diffusion term which is defined by a stochastic integral of a fuzzy process wrt one-dimensional Brownian motion. He develops a theory of existence and uniqueness of the solution for such systems and demonstrates how the technical machinery can be applied to ...
