In this paper, we considered the two-dimensional fractional-order Black-Scholes model in the Liouville-Caputo sense. The Black-Scholes model was an important tool in the financial market, used for determining option prices in the European-style marke

This study examines an epidemiological model known as the susceptible-exposed-infected-hospitalized-recovered (SEIHR) model, with and without impulsive vaccination strategies. First, the model was analyzed without impulsive vaccination in the presenc

In this paper, we investigate the effect of body weight on the lumbar spine with different spinal canal sizes when humans bend down by using the finite element method. Lumbar spinal stenosis is the narrowing of the spinal canal. This dysfunction can

Abstract Fly ash solid waste from a power plant was applied in a solar cell application for the first time. A doctor blade was used to coat FTO-glass with a composite film of mixed fly ash and PEDOT:PSS (FP). XRD, FTIR, SEM, EDX, and BET analyses wer

In this paper, we proposed a mathematical model of the population density of Indo-Pacific mackerel (Rastrelliger brachysoma) and the population density of small fishes based on the impulsive fishery. The model also considers the effects of the toxic

Abstract In this paper, we introduce the notions of proximal Berinde g-cyclic contractions of two non-self-mappings and proximal Berinde g-contractions, called proximal Berinde g-cyclic contraction of the first and second kind. Coincidence best proxi

Lumbar spinal stenosis (LSS) is a common disorder of the human lumbar spine found in elderly people. The disease can cause severe pain in patients, especially when people bend down. The main purpose of this paper is to develop the finite element simu

In this paper, a mathematical model for Streptococcus suis infection is improved by using the fractional order derivative. The modified model also investigates the transmission between pigs and humans. The proposed model can classify the pig populati

Abstract In this paper, we investigate the effect of insecticide on the population dynamics of brown planthoppers (a major insect pest of rice) and Cyrtorhinus lividipennis (one of the natural enemies of brown planthoppers) by developing an impulsive

In this paper, a mathematical model for African swine fever is modified by considering the swine farm with the contaminated human vector that is able to infect and spread the disease among swine farms. In the developed model, we have divided the swin
