Spontaneous emission of a quantum particle under strong Stark interaction with resonant vacuum field

It has been shown that strong Stark interaction of a quantum particle with a vacuum electromagnetic field reduces the speed of the one-quantum spontaneous radiation and leads to additional shift of frequency of radiation transition.Comment: 6 page

Interaction of pediatrician, oncologist and therapist in the complex therapy of children’s patients

The interaction of pediatricians with pediatric oncologists is important for the optimization and treatment of children suffering from oncological diseases. Modern practice strives for a combined approach that includes the interaction of specialists from different fields of medicine in order to improve the quality of medical services provided. The purpose of the article is to provide pediatricians with updated information about the state of pediatric cancer care. In this paper, the following aspects are highlighted, which are aimed at optimizing and applying innovations in the treatment of oncological diseases in children, in particular: reducing the toxicity of drugs in treatment, studying cancer biology, considering new treatment methods, monitoring the disease, since these areas are key topics of general pediatric medicine. The review of immunotherapy and combined approaches in the treatment of oncological diseases of children was carried out. Attention is paid to precision oncology aimed at identifying drugs that will work with specific mutations in the field of tumor destruction. Issues related to the interaction of a pediatrician, oncologist and ENT in combination therapy are also considered

Existence of superposition solutions for pulse propagation in nonlinear resonant media

Existence of self-similar, superposed pulse-train solutions of the nonlinear, coupled Maxwell-Schr\"odinger equations, with the frequencies controlled by the oscillator strengths of the transitions, is established. Some of these excitations are specific to the resonant media, with energy levels in the configurations of $\Lambda$ and $N$ and arise because of the interference effects of cnoidal waves, as evidenced from some recently discovered identities involving the Jacobian elliptic functions. Interestingly, these excitations also admit a dual interpretation as single pulse-trains, with widely different amplitudes, which can lead to substantially different field intensities and population densities in different atomic levels.Comment: 11 Pages, 6 Figures, presentation changed and 3 figures adde
