Individuals Strategies and Predator–Prey Game Models in Deterministic and Random Settings

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The authors propose a new predator–prey game model by integrating two optional strategies into prey species: cooperative and isolation strategies. An investigation of the evolutionary impact on predator–prey system dynamics is given. The model utilizes a replicator equation to track changes in the frequency of cooperative strategy among preys,

On Generalized Avicenna Numbers

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Avicenna numbers that we define in this paper, are a class of figurate numbers, including icosahedral, octahedral, tetrahedral, dodecahedral, rhombicosidodecahedral numbers and cubes, play a key role in mathematics, physics and various scientific fields.

Diffusion Schrödinger bridge models for high‐quality MR‐to‐CT synthesis for proton treatment planning

open access: yesMedical Physics, EarlyView.
Abstract Background In recent advancements in proton therapy, magnetic resonance (MR)‐based treatment planning is gaining momentum due to its excellent soft tissue contrast and high potential to minimize extra radiation exposure compared to traditional computed tomography (CT)‐based methods. This transition underscores the critical need for accurate MR‐

MSTMM‐Validated Machining Efficiency and Surface Roughness Improvement Using Evolutionary Optimization Algorithm

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Ultra‐precision machining (UPM) has been extensively employed for the production of high‐end precision components. The process is highly precise, and the associated cost of production is also high. Optimization of machining parameters in UPM can significantly improve machining efficiency and surface roughness. This study proposes an innovative
