Communications via the radio artificial earth satellite: Design of the tracking diagram and features for conducting QSO

A detailed examination is made of the operation of a transmitting artifical Earth satellite. A tracking diagram for the satellite is constructed. The zone of radio visibility can be determined based on the techniques proposed

A continuous analog of the binary Darboux transformation for the Korteweg-de Vries equation

In the KdV context we put forward a continuous version of the binary Darboux transformation (aka the double commutation method). Our approach is based on the Riemann-Hilbert problem and yields a new explicit formula for perturbation of the negative spectrum of a wide class of step-type potentials without changing the rest of the scattering data. This extends the previously known formulas for inserting/removing finitely many bound states to arbitrary sets of negative spectrum of arbitrary nature. In the KdV context our method offers same benefits as the classical binary Darboux transformation does.Comment: To appear in Studies in Applied Mat

Music’s Potential Effects On Surgical Performance

Music in the OR is highly prevalent, with most facilities being equipped with a stereo system. The role of music on surgical performance and subsequent patient outcomes has been highly debated in the literature. This review will attempt to elucidate the positive as well as deleterious effects music may have on the surgical team
