FLASH radiotherapy is an emerging and highly promising technique in cancer treatment that delivers ultra-high dose rate radiation in extremely short pulses—typically within milliseconds.
This novel mode of dose delivery triggers the so-called FLASH effect, which has demonstrated the remarkable ability to spare healthy tissues while maintaining effective tumor control, potentially...

47. Quantum motion of a single photon in a nanofiber with randomly located quantum dots

In the work within the framework of the gauge symmetry group SU(2)xU(1) the Yang-Mills equation for a single photon is considered. Using the equations in partial derivatives of the first order, an equation for the wave function of the photon is obtained in the form of an equation of the second order taking into account the random environment. The problem of the motion of a single photon in a...

When a charged point particle moves parallel to the axis of a two-layer cylindrical metal-dielectric waveguide with a sufficiently small thickness of the internal dielectric coating, its radiation field has a single-mode character, i.e., the frequency distributions of both the longitudinal and transverse impedances of the waveguide contain a single, clearly expressed narrow-band resonance....

32. Study of the influence of ultrasonic radiation on aqueous solutions of methane, ethylene and their mixtures

One of the methods of influencing chemical reactions is the use of ultrasound. In this case, most chemical reactions in ultrasonic fields occur in aqueous solutions in the presence of cavitation. It is known that under the influence of cavitation, the direction and speed of chemical reactions occurring in a solution can change significantly. In a number of cases, processes may occur that are...
