A mathematical model with piecewise constant arguments of colorectal cancer with chemo-immunotherapy

Bozkurt, Fatma; Yousef, Ali; Bilgil, Halis; Baleanu, Dumitru (PERGAMON-ELSEVIER SCIENCE LTD, 2023)

We propose a new mathematical model with piecewise constant arguments of a system of ODEs to investigate the growth of colorectal cancer and its response to chemo-immunotherapy. Our main target in this paper is to analyze ...
Triple Sampling Inference Procedures for the Mean of the Normal Distribution When the Population Coefficient of Variation Is Known

Alhajraf, Ali; Yousef, Ali; Hamdy, Hosny (MDPI, 2023)

This paper discusses the triple sampling inference procedures for the mean of a symmetric distribution-the normal distribution when the coefficient of variation is known. We use the Searls' estimator as an initial estimate ...
