Effects of Alumina–Tantalum Hybrid Nanofragment on Engine Oil Flow Using a New Local Thermal Nonequilibrium Formulation

Complexity, Volume 2025, Issue 1, 2025.
The aim of this work is to study the alumina–tantalum/motor oil hybrid nanoliquid flow in a porous cavity subjected to a uniform magnetic field. We have used the Darcy–Bénard convection model for the momentum equation and a new local thermal nonequilibrium formulation for heat transport.

MCOA: A Multistrategy Collaborative Enhanced Crayfish Optimization Algorithm for Engineering Design and UAV Path Planning

International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.
The crayfish optimization algorithm (COA) is a recent bionic optimization technique that mimics the summer sheltering, foraging, and competitive behaviors of crayfish. Although COA has outperformed some classical metaheuristic (MH) algorithms in preliminary studies, it still manifests the shortcomings of falling into local optimal stagnation, slow ...

A New Generalization of Leonardo Sequences: Biperiodic Leonardo Sequence

Journal of Mathematics, Volume 2025, Issue 1, 2025.
In this study, we define a new type of number sequence called biperiodic Leonardo sequence by the recurrence relation Lena,b=aLen−1+Len−2+1 (for even n) and Lena,b=bLen−1+Len−2+1 (for odd n) with the initial conditions Le0a,b=Le1a,b=1. We obtained the characteristic function, generating function, and Binet’s formula for this sequence and propose a ...

A univariate time varying analysis of periodic ARMA processes

, 2014
The standard approach for studying the periodic ARMA model with coefficients that vary over the seasons is to express it in a vector form. In this paper we introduce an alternative method which views the periodic formulation as a time varying univariate ...

Osteopontin deletion attenuates cyst growth but exacerbates fibrosis in mice with cystic kidney disease

Physiological Reports, Volume 12, Issue 17, September 2024.
Abstract Osteopontin (OPN) is a multi‐functional glycoprotein that coordinates the innate immune response, prevents nanocrystal formation in renal tubule fluid, and is a biomarker for kidney injury. OPN expression is markedly increased in cystic epithelial cells of polycystic kidney disease (PKD) kidneys; however, its role in PKD progression remains ...

Scalar brane backgrounds in higher order curvature gravity

, 2003
We investigate maximally symmetric brane world solutions with a scalar field. Five-dimensional bulk gravity is described by a general lagrangian which yields field equations containing no higher than second order derivatives.

A detection and rerouting mechanism for platoon control of non‐linear autonomous vehicles under denial of service attacks

IET Control Theory &Applications, Volume 18, Issue 6, Page 798-813, April 2024.
This paper introduces a novel mechanism for enhancing distributed adaptive platoon control of non‐linear autonomous connected vehicles in the presence of denial of service attacks. The proposed approach includes real‐time detection and rerouting of communication topology, along with a controller adapted to the changing communication topology.
