Optical Field Transmission Analysis of an All-Fiber Signal Combiner With a Dumbbell Shape

open access: yesIEEE Photonics Journal, 2022
In this paper, the optical field transmission characteristics of an all-fiber signal combiner with a dumbbell shape and its application in laser beam combining are analyzed theoretically. Based on the three-layer waveguide model, the mode characteristics

Semi-Dilute Dumbbells: Solutions of the Fokker–Planck Equation

open access: yesJ, 2021
Spring bead models are commonly used in the constitutive equations for polymer melts. One such model based on kinetic theory—the finitely extensible nonlinear elastic dumbbell model incorporating a Peterlin closure approximation (FENE-P)—has previously ...

Investigating the biomechanics of the biceps brachii muscle during dumbbell curl exercise: A comprehensive approach

open access: yesEuropean Mechanical Science, 2023
Investigation of the mechanical behavior of the biceps brachii (BB) muscle at different dynamic forces is essential to improve training techniques, prevent sports injuries and optimize rehabilitation results.

Optimization of Mathematical Function-Shaped Fracture Distribution Patterns for Multi-Stage Fractured Horizontal Wells

open access: yesEnergies, 2023
A conventional oil and gas well does not have a natural production capacity, which necessitates a hydraulic fracturing operation. The effectiveness of the fracturing directly impacts the economic benefit of a single well.

Derivation of Two-Fluid Model Based on Onsager Principle

open access: yesEntropy, 2022
Using the Onsager variational principle, we study the dynamic coupling between the stress and the composition in a polymer solution. In the original derivation of the two-fluid model of Doi and Onuki the polymer stress was introduced a priori; therefore,

Clusters formed by dumbbell-like one-patch particles confined in thin systems

open access: yesScientific Reports, 2021
Performing isothermal-isochoric Monte Carlo simulations, I examine the types of clusters that dumbbell-like one–patch particles form in thin space between two parallel walls, assuming that each particle is synthesized through the merging of two particles,

Zika virus dumbbell-1 structure is critical for sfRNA presence and cytopathic effect during infection

open access: yesmBio, 2023
All flaviviruses contain conserved RNA structures in the 3′ untranslated region (3′ UTR) that are important for flavivirus RNA replication, translation, and pathogenesis.

Stability of a Dumbbell Micro-Swimmer

open access: yesMicromachines, 2019
A squirmer model achieves propulsion by generating surface squirming velocities. This model has been used to analyze the movement of micro-swimmers, such as microorganisms and Janus particles.
