    Implicit Relaxed and Hybrid Methods with Regularization for Minimization Problems and Asymptotically Strict Pseudocontractive Mappings in the Intermediate Sense by Lu-Chuan Ceng, Qamrul Hasan Ansari, Ching-Feng Wen

    Published 2013-01-01
    “…We first introduce an implicit relaxed method with regularization for finding a common element of the set of fixed points of an asymptotically strict pseudocontractive mapping S in the intermediate sense and the set of solutions of the minimization problem (MP) for a convex and continuously Frechet differentiable functional in the setting of Hilbert spaces. The implicit relaxed method with regularization is based on three well-known methods: the extragradient method, viscosity approximation method, and gradient projection algorithm with regularization. …”

    Transient Diffusiophoresis of a Spherical Colloidal Particle by Hiroyuki Ohshima

    Published 2025-01-01
    “…A general theoretical approach is introduced to analyze the time-dependent, transient diffusiophoresis of a charged spherical colloidal particle in a symmetrical electrolyte solution when an electrolyte concentration gradient is suddenly applied. We derive a closed-form approximate expression for the relaxation function <i>R</i>(<i>t</i>), which describes the time course of the diffusiophoretic mobility of a weakly charged spherical colloidal particle possessing a thin electrical double layer. …”

    Nonlocal Electromechanical Effects within a cubic-symmetry dielectric materials by A.R. El-Dhaba

    Published 2025-09-01
    “…In this paper, we investigate the effect of nonlocality on the electromechanical phenomenon in anisotropic elastic dielectric materials with cubic symmetry using strain gradient theory of elasticity. The first stage involves applying the variational principle to the strain energy functional and the virtual work done by external forces, including mechanical forces, double forces, and electrical forces, known as the Hamiltonian principle. …”

    The Effect Of Optimizers On The Generalizability Additive Neural Attention For Customer Support Twitter Dataset In Chatbot Application by Sinarwati Mohamad Suhaili, Naomie Salim, Mohamad Nazim Jambli

    Published 2024-02-01
    “…Optimizers primarily control the adjustment of model parameters such as weight and bias to minimize a loss function during training. Adaptive optimizers such as ADAM have become a standard choice and are widely used for their invariant parameter updates' magnitudes concerning gradient scale variations, but often pose generalization problems. …”

    eDNA Metabarcoding Reveals the Depth-Structured Variation of Coral Reef Fish by Jinfa Zhao, Lin Lin, Yong Liu, Teng Wang, Yu Liu, Yayuan Xiao, Jianzhong Shen, Hongyu Xie, Hai Huang, Qiuying Han

    Published 2025-05-01
    “…Importantly, our findings revealed distinct depth-structured variation among different functional groups of coral reef fish. Large carnivorous fish initially increased and then decreased along the depth gradient from 0 to 60 m, with a turning point around 20 m, while large herbivorous fish displayed the opposite trend. …”
