Diseases caused by the Hepatitis C Virus (HCV) can reach a chronic level and even lead to more serious diseases such as cirrhosis and fibrosis. In this respect, early detection of HCV infection is important. HCV-related diseases can usually be detected by applying the HCV test as a result of observing certain symptoms. However, In the early stages of infection, when symptoms are not yet evident, patients rarely resort to HCV testing. This shows that different materials are needed to guide HCV testing in order to detect HCV-related diseases early. Developing artificial intelligence technology can be an alternative to these materials, which are necessary for the early diagnosis of the disease. In this study, artificial intelligence technology was used to determine the disease status of individuals by using blood data. In the study in which the blood values of 615 individuals were used; preprocessing, filtering, feature selection, and classification processes were applied. Correlation method was used for feature selection. The features with high correlation values are selected and given as input to 5 different classification algorithms. According to the results of the study, the best classification success for the detection of HCV patients was obtained with the K-Nearest Neighbor (KNN) algorithm as 99.1%. Looking at the results of this classification, it is understood that thanks to the algorithm used, clear information about hepatitis infection can be obtained from different blood values.

Silicon-organic polymers containing thioacetamide, thiocarbamide, and dioxothiocarbamide groups were used in this investigation. The polymers were produced by the hydrolytic poly-condensation reaction of silicon-organic monomer, 3-triethoxysilylpropylamine. Au(III) sorption onto the polymers has been studied. The optimal condition of the sorption is confirmed by sorption experiments which were carried out at various times and in acidic solution conditions. Based on the result of the instrumental analysis and the values of thermodynamic parameters, such as ΔG°, ΔH°, and ΔS° can be concluded that Au(III) can be connected with the electro-donor nitrogen and sulfur atoms of the functional group of the polymer by chemical and coordination bonds.

In this work, the influence of catalyst preparation temperature on its structure was investigated. We have synthesized 12 different Ni/ZrO2 catalysts by varying the calcination temperature, time, and active metal content, and these catalysts will be further used in the carbon dioxide methanation reaction. Structure and properties of the catalysts were determined using XRD and SEM analysis. Therefore, Ni content of the catalysts were measured by ICP-OES.Regarding to the crystal size calculation using XRD data by Scherer equation, when calcination time was increased the average crystal size of nickel oxide was decreased from 42.38 nm to 38.93 nm whereas it decreased to 39.23 nm when the calcination temperature was increased. This shows that the distribution of active metals in the catalyst increases when the heat treatment parameters are increased. In addition, it can be assumed that the activity of the catalyst can be enhanced when the calcination temperature and time were increases.

This study presents the estimations of the 3D motion of a moving object in an image sequence taken from a monocular camera through linear and non-linear equations and determines the differences between linear and non[1]linear algorithms in terms of theoretical level and estimation accuracy with noisy point correspondences. Firstly, we investigated linear and non-linear algorithms for determining 3D motion at the theoretical level. Second, we estimated the 3D motion of the moving object in an image frame at two different instants of time with feature point correspondences in real-time. Finally, we implemented an accuracy analysis of the results from the linear and non-linear estimations. We showed that the non-linear approach produced more accurate results than the linear approach from noisy point correspondences.

Our aim is using the Coulomb wave function discrete variable representation method (CWDVR) for the calculation of collision problem in first time. Nonrelativistic collision of antiproton with hydrogen atom is described by solving the time-dependent Schrodinger equation numerically. Two collision amplitudes are used for calculation of the differential cross sections, one of them corresponds to impact parameter of the projectile while other one is determined by projectile momentum transfer and found by Fourier transform of the first one. The ionization amplitude calculated by projecting of the wave function onto continuum wave function of the ejected electron. The differential cross sections calculated depending on projectile impact energy, scattering angle and electron ejection energy and angles, which is a result that can be measured experimentally. Our results are in good agreement with the relativistic calculation results.

This paper reports on the progress of the liquid-solid phase transition modeling of water in open channel flow by using the lattice Boltzmann method with the immersed boundary modification. The phase transition in a fluid flow has a moving interface between the liquid and solid state, which leads complicated treatments in existing numerical models. By applying the immersed boundary modification in the lattice Boltzmann method and the non-iterative enthalpy approach for the separation of the states, the moving boundary of the melting or solidification front is solved without any difficulty. The ice bed and the submerged ice cover under dynamic flow conditions is exercised to demonstrate the model performance. The model is extremely suitable in the formulation in terms of its simple and compact framework extendable to any dimensions.

Our main motivation question is "Is there any relation between the non-coding region and useless error- correcting codes?". Then we focused CDS and non-CDS areas instead of exon and intron, because CDS involves in process of synthesis a protein and is involved by exons. We get the data of the genes from NCBI [21]. In this study, we introduce the method Fi-noncds that is used for determining the non-CDS region by using error-correcting codes. We obtained that the error-correction codes that can't correct any codes named zero error- correcting code, placed in non-CDS areas, densely. This result shows that non-CDS regions (non-coding areas in DNA) match zero error-correcting codes (useless error-correcting code). Frame lengths 7,8,9 and 10,11,12,13 and 14 were tested by the method. Optimal result for selected genes (TRAV1-1, TRAV1-2, TRAV2, TRAV7, WRKY33, HY5, GR-RBP2) is frame length 8, n = 7, k = 2, dnaNo = 1. Moreover, optimal results of the algorithm Fi-noncds matched the best sequence length 8 as in [1].
我们的主要动机问题是“非编码区和无用的纠错码之间是否存在任何关系?”然后我们将重点放在CDS和非CDS区域，而不是外显子和内含子，因为CDS参与蛋白质的合成过程，并且由外显子参与。我们从NCBI[21]中获得基因数据。在本研究中，我们介绍了用纠错码来确定非cds区域的方法Fi-noncds。我们得到了不能纠错任何码的纠错码，称为零纠错码，密集地放置在非cds区域。这一结果表明，非cds区域(DNA中的非编码区域)与零纠错码(无用的纠错码)匹配。采用该方法对帧长7、8、9、10、11、12、13和14进行了测试。所选基因(TRAV1-1、TRAV1-2、TRAV2、TRAV7、WRKY33、HY5、GR-RBP2)的最佳结果为帧长8,n = 7, k = 2, dnaNo = 1。此外，Fi-noncds算法的最优结果与[1]中的最佳序列长度8相匹配。

Turkey's rapid population and economic growth have caused a significant increase in energy demand over the last two decades. As a result, a process of evaluating alternative energy strategies and policies was required to be formulated carefully along with the country's longer-term decarbonisation aims. Although Turkey's considerable renewable energy potential exists, its dependency on foreign energy and its dramatically depreciating currency have been the main drivers of revisions to these renewable energy-related policies. This paper aims to demonstrate and evaluate all the strategies and challenges of Turkey's green steps toward a sustainable future. Sustainable developments of many developed countries have been examined and compared to assess Turkish strategies and significant policies that have been taken. As findings, it has been revealed that policy revisions regarding the use of domestic technology in green power plants decelerate investments for a short time. However, it has been found that renewable energy patent applications have declined, although domestic technology in green energy plants has been promoted through these policy revisions. As a result of this dilemma, the quality and effectiveness of green research and development (R&D) in Turkey have been investigated and then benchmarked with most leading countries. It has been observed that there is no correlation and relation between the patent application and the articles on renewable energy. Therefore, the paper has provided insight into new policies and strategies to enhance the productivity of R&D for both Turkey and developing similar countries. Consequently, potential measures to increase Turkey's green energy use and production are discussed and proposed systematically, considering those findings.

In this work we employ the split-step technique combined with a Legendre pseudospectral representation to solve various time-dependent GrossPitaevskii equations (GPE). Our findings based on the numerical accuracy of this approach applied for one-dimensional (1D) and two-dimensional (2D) problems show that it can provide accurate and stable solutions. Moreover, this approach has been applied to study the dynamics of the Bose-Einstein condensate which is modeled with the GPE. The breathing of condensate with a repulsive and attractive interactions trapped in 1D and 2D harmonic potentials has been simulated as well.
