| 1 | Bright and dark soliton solutions for some nonlinear fractional differential equations显示文摘In this work, we propose a new approach, namely ansatz method, for solving fractional differential equations based on a fractional complex transform and apply it to the nonlinear partial space–time fractional modified Benjamin–Bona–Mahoney(m BBM) equation, the time fractional m Kd V equation and the nonlinear fractional Zoomeron equation which gives rise to some new exact solutions. The physical parameters in the soliton solutions: amplitude, inverse width, free parameters and velocity are obtained as functions of the dependent model coefficients. This method is suitable and more powerful for solving other kinds of nonlinear fractional PDEs arising in mathematical physics. Since the fractional derivatives are described in the modified Riemann–Liouville sense. | Ozkan Guner Ahmet Bekir | 2016 | Chinese Physics B2016，25，3： | 6 |
| 2 | Exact solutions of nonlinear fractional differential equations by (G'/G)-expansion method显示文摘In this paper,we use the fractional complex transform and the(G'/G)-expansion method to study the nonlinear fractional differential equations and find the exact solutions.The fractional complex transform is proposed to convert a partial fractional differential equation with Jumarie’s modified Riemann–Liouville derivative into its ordinary differential equation.It is shown that the considered transform and method are very efficient and powerful in solving wide classes of nonlinear fractional order equations. | Ahmet Bekir zkan Güner | 2013 | Chinese Physics B2013，22，11： | 5 |

| 4 | Investigation of soliton solutions with different wave structures to the(2+1)-dimensional Heisenberg ferromagnetic spin chain equation显示文摘The principal objective of this article is to construct new and further exact soliton solutions of the(2+1)-dimensional Heisenberg ferromagnetic spin chain equation which investigates the nonlinear dynamics of magnets and explains their ordering in ferromagnetic materials.These solutions are exerted via the new extended FAN sub-equation method.We successfully obtain dark,bright,combined bright-dark,combined dark-singular,periodic,periodic singular,and elliptic wave solutions to this equation which are interesting classes of nonlinear excitation presenting spin dynamics in classical and semi-classical continuum Heisenberg systems.3D figures are illustrated under an appropriate selection of parameters.The applied technique is suitable to be used in gaining the exact solutions of most nonlinear partial/fractional differential equations which appear in complex phenomena. | M S Osman K U Tariq Ahmet Bekir A Elmoasry Nasser S Elazab M Younis Mahmoud Abdel-Aty | 2020 | Communications in Theoretical Physics2020，72，3： | 4 |
| 5 | Hepatic cystic echinococcosis:Percutaneous treatment as an outpatient procedure显示文摘Objective:To demonstrate utility and safety of the puncture aspiration injection and reospiration(PAIR)technique for outpatients.Methods:Percutaneous treatment with US guidance was applied to 33 patients for 44 cysts.Patients treated with the PAIR technique,were outpatients.PAIR and catheterization technique were evaluated for efficacy and safety of procedure and complication rates.Results:Thirty-five of 44 cysts were treated with the PAIR and 9 of 44 were treated with the catheterization technique.The success rate of the cysts Gharbi type 1(CEI)and type 2(Ct3a)treated with the PAIR technique was 1009.hi the follow up of 9 cysts treated with the catheterization technique,2 of them(22%)developed cyst infection and 1(11%)developed a biliary fistula.Conclusions:The PAIR technique was found to be an effective and safe approach in order to treat Gharbi type 1 and type 2 cysts percutaneously for outpatients.It has a very low complication rate in comparison with the catheterization technique.So every effort should be mode to finish the treatment with PAIR technique. | Mert Kroglu Bekir Erol Cemil Gürses Baris Türkbey Cem Yunus Bas Ahmet Sükrü Alparslan Banu Kale Kroglu Iclal Erdem Toslak Bülent eki Okan Akhan | 2014 | Asian Pacific Journal of Tropical Medicine2014，7，3： | 4 |
| 6 | Analysis of serum antibody profile against H pylori VacA and CagA antigens in Turkish patients with duodenal ulcer显示文摘AIM: To investigate the frequency of seropositivity aga- inst CagA, VacA proteins and to determine their indepen- dent effects on the development of duodenal ulcer (DU) in Turkish patients. METHODS: The study was designed as a prospective one from a tertiary referral hospital. Dyspeptic patients who were referred to our endoscopy unit for upper gas- trointestinal endoscopy between June 2003 and March 2004 and diagnosed to have DU or nonulcer dyspepsia (NUD) were included. Biopsies from the antrum and body of the stomach were taken in order to assess the current H pylori status by histology, rapid urease test and culture. Fasting sera were obtained from all patients and H pylori status of all sera was determined by IgG antibo- dies using an enzyme-linked immunosorbent assay (ELI- SA) kit. All seropositive patients were further analysed using Western blot assays detecting IgG antibodies aga- inst CagA and VacA proteins. The χ2 test was used for statistical comparison of the values and age-sex adjusted multiple regression analysis was used to determine the independent effects of CagA and VacA seropositivities on the development of DU. RESULTS: Sixty-three patients with DU and 62 patients with NUD were eligible for the final analysis. Seropositi- vity for anti-CagA was detected in 51 of 62 (82%), andin 55 of 63 (87%) patients with NUD and DU, respec- tively (p = no significance), and seropositivity for anti- VacA was found in 25 of 62 (40% ) and in 16 of 63 (25%) patients, with NUD and DU, respectively. CONCLUSION: These findings suggest that none of the- se virulence factors is associated with the development of DU in the studied Turkish patients with dyspepsia. | Yusuf Erzin Sibel Altun Ahmet Dobrucali Mustafa Aslan Sibel Erdamar Ahmet Dirican Murat Tuncer Bekir Kocazeybek | 2006 | World Journal of Gastroenterology2006，12，42： | 3 |
| 7 | Density-Dependent Conformable Space-time Fractional Diffusion-Reaction Equation and Its Exact Solutions显示文摘In this article, a special type of fractional differential equations(FDEs) named the density-dependent conformable fractional diffusion-reaction(DDCFDR) equation is studied. Aforementioned equation has a significant role in the modelling of some phenomena arising in the applied science. The well-organized methods, including the exp(-φ(ε))-expansion and modified Kudryashov methods are exerted to generate the exact solutions of this equation such that some of the solutions are new and have been reported for the first time. Results illustrate that both methods have a great performance in handling the DDCFDR equation. | Kamyar Hosseini Peyman Mayeli Ahmet Bekir Ozkan Guner | 2018 | Communications in Theoretical Physics2018，69，1： | 2 |
