We present a general procedure for finding recurrence relations of the radial wavefunctions for Nth-dimensional isotropic harmonic oscillators and hydrogenlike atoms. PACS numbers: 03.65.Ge, 31.15.+q

In this study, we investigate the energy partition of four confined circular-ribbon flares (CRFs) that occurred close to solar disk center. The are observed simultaneously by Solar Dynamics Observatory (SDO), Geostationary Operational Environmental Satellites (GOES), and Ramaty Hight Energy Spectroscopic Imager (RHESSI). We calculate different components, including radiative outputs in ranges 1...
