Through recent years many researchers have developed methods to estimate the self-similarity and long memory parameter that is best known as the Hurst parameter. In this paper, we set a comparison between nine different methods. Most of them use the deviations slope to find an estimate for the Hurst parameter like Rescaled range (R/S), Aggregate Variance (AV), and Absolute moments (AM), and some depend on filtration technique like Discrete Variations (DV), Variance versus level using wavelets (VVL) and Second-order discrete derivative using wavelets (SODDW) were the comparison set by a simulation study to find the most efficient method through MASE. The results of simulation experiments were shown that the performance of the meth

Fenton electrochemical process has been addressed to treat wastewater which is very popular because of its high efficiency and straightforward design. One of the advanced oxidation processes (AOPs) is electro-Fenton (EF) process, and electrode material significantly affects its performance. Nickel foam was chosen as the source of electro-generated hydrogen peroxide (H2O2) due to its good characteristics. In the present study, the main goals were to explore the effects of operation parameters (FeSO4 concentration, current density, and electrolysis time) on the catalytic performance that was optimized by r
... Show MoreDeepfake is a type of artificial intelligence used to create convincing images, audio, and video hoaxes and it concerns celebrities and everyone because they are easy to manufacture. Deepfake are hard to recognize by people and current approaches, especially high-quality ones. As a defense against Deepfake techniques, various methods to detect Deepfake in images have been suggested. Most of them had limitations, like only working with one face in an image. The face has to be facing forward, with both eyes and the mouth open, depending on what part of the face they worked on. Other than that, a few focus on the impact of pre-processing steps on the detection accuracy of the models. This paper introduces a framework design focused on this asp

Show MoreThe aim of this study is to investigate the relationship between microRNA 378 and BMP15 gene expression levels in blood samples collected from 50 healthy fertile females as controls and 50 hyperprolactinemia infertile females by quantitative real-time polymerase chain reaction (RT-qPCR). Specific primers were designed for this purpose based on the sequences of microRNA 378 and BMP15 retrieved from NCBI and designed by primer 3 software. The result assessing the expression level of BMP15 in hyperprolactinemia (HPL) was 0.220, while the control group's fold change value was 1.000. The HPL group showed downregulation in the expression of the BMP15 gene. While the fold expression values of the miRNA378 gene in the hyperprolactinemia

Culex mosquitoes are important vectors of several human and animal diseases, including filariasis and various forms of encephalitis, making the control of their larvae a public health priority. In this study, Culex pipiens larvae were collected from a pond within the botanical garden of the Ibn Al-Haitham College of Education for Pure Sciences, and Aloe vera leaves were also collected from the same college's gardens. Aqueous Aloe vera extract was prepared and tested for its larval bactericidal activity against Culex pipiens mosquitoes under controlled laboratory conditions. Larvae of all four larval stages were exposed to a range of extract concentrations (10%, 15%, 20%, and 25%) in five replicates, each contai
