73. Motion of electron near black hole

We consider a black hole metric in which the spacetime outside the event horizon is rotating with a constant angular velocity. From this metric, we derive the equations of motion. We then calculate the radii of the light cylinders—two real solutions arising from a cubic equation (the third being complex and unphysical). We also identify the radii corresponding to steady (circular) orbits....

91. Obtaining various magnetic fields with a two-dimensional system of currents

The importance of magnetic fields in modern physics is great, and mankind has known for a long time how a moving charge creates a magnetic field. That is, if we know the coordinates and velocities of charges moving in space or the current density at every point in space, then we can determine what the magnetic field induction is and where it is directed at any point.
The difficulty of...

87. Quadruplexes in DNA nanotechnology for non-enzymatic nucleic acid diagnostics

Quadruplexes are highly structured forms of DNA consisting of stacked guanine tetrads linked by hydrogen bonds, which require the presence of cations, positively charged ions, such as potassium. Their high stability has made quadruplexes a good candidate for the development of new and effective diagnostic methods. Using quadruplexes, an isothermal diagnostic method for the detection of nucleic...

85. Solar Wind magnetosphere coupling during the 2024 Geomagnetic storms

Geomagnetic storms pose a threat to both technological systems and human health, making them a crucial area of research. In this study, we analyze the interaction between the solar wind and the magnetosphere during the strong geomagnetic storms of 2024 (March 3, March 24, and May 11). The research is based on the horizontal component of Earth’s magnetic field (H) from the Dusheti Geomagnetic...
