The generalized Marchenko Method in the inverse scattering problem for a first-order linear system with energy-dependent potentials
Aktosun, Tuncay; Ercan, Ramazan; Ünlü, Mehmet (2023)The Marchenko method is developed in the inverse scattering problem for a linear system of first-order differential equations containing potentials proportional to the spectral parameter. The corresponding Marchenko system ... -
A generalized method for the Darboux transformation
Aktosun, Tuncay; Ünlü, Mehmet (AIP Publishing, 2022)A method is presented to obtain the change in the potential and in the relevant wavefunction of a linear system of ordinary differential equations containing a spectral parameter, when that linear system is perturbed and ... -
Inverse problems for selfadjoint Schrodinger operators on the half line with compactly supported potentials
Aktosun, Tuncay; Sacks, Paul; Ünlü, Mehmet (Amer Inst Physics, 2015)For a selfadjoint Schrodinger operator on the half line with a real-valued, integrable, and compactly supported potential, it is investigated whether the boundary parameter at the origin and the potential can uniquely be ... -
The Marchenko method to solve the general system of derivative nonlinear Schrodinger equations
Aktosun, Tuncay; Ercan, Ramazan; Ünlü, Mehmet (AIP Publishing, 2023)A system of linear integral equations is presented, which is the analog of the system of Marchenko integral equations, to solve the inverse scattering problem for the linear system associated with the DNLS (derivative ... -
Urinary incontinence in premenopausal women: prevalence, risk factors and impact on quality of life
Ünlü, Mehmet; Üstüner, Işık; Güven, Emine Seda Güvendağ; Şentürk, Şenol; Şahin, Figen Kır (Wiley, 2014)ObjectivesTo determine the prevalence and risk factors of urinary incontinence (UI), and assess its impact on the quality of life (QOL) in premenopausal women. MethodsIn this cross-sectional study, 690 women aged from 18 ...
