L-Index in Joint Variables: Sum and Composition of an Entire Function with a Function With a Vanished Gradient

open access: yesFractal and Fractional, 2023
The composition H(z)=f(Φ(z)) is studied, where f is an entire function of a single complex variable and Φ is an entire function of n complex variables with a vanished gradient.

A Gradient-Based Particle-Bat Algorithm for Stochastic Configuration Network

open access: yesApplied Sciences, 2023
Stochastic configuration network (SCN) is a mathematical model of incremental generation under a supervision mechanism, which has universal approximation property and advantages in data modeling. However, the efficiency of SCN is affected by some network

Passive Control of Silane Diffusion for Gradient Application of Surface Properties

open access: yesMicromachines, 2021
Liquid lithography represents a robust technique for fabricating three-dimensional (3D) microstructures on a two-dimensional template. Silanization of a surface is often a key step in the liquid lithography process and is used to alter the surface energy

Gradient upon gradient

open access: yesThe Journal of Cell Biology, 2005
One RanGTP gradient builds on another to spatially guide mitotic spindle assembly, say Maiwen Caudron, Eric Karsenti (European Molecular Biology Laboratory, Heidelberg, Germany), and colleagues. Figure The RanGTP-importin β gradient (red) promotes microtubule nucleation (blue) and stabilization (green).

Planar cell polarity: intracellular asymmetry and supracellular gradients of Dachsous

open access: yesOpen Biology, 2022
The slope of a supracellular molecular gradient has long been thought to orient and coordinate planar cell polarity (PCP). Here we demonstrate and measure that gradient.
