Hardware-software system for monitoring of atmospheric water vapor structure in the city of Kazan

© Published under licence by IOP Publishing Ltd. Methodology and software to reconstruct the spatial-temporal structure of water vapor in the troposphere by GNSS signals measured by ground-based receivers is developed. In this paper, measurements of a satellite navigation system receiver network located near the city of Kazan are used. It is shown that using a tomographic approach it is possible to reconstruct the altitude profile of the refractive index in the lower atmosphere and its space-time variations. The tomography method gives less smoothed results than Tikhonov's method

Production of {\pi}+ and K+ mesons in argon-nucleus interactions at 3.2 AGeV

First physics results of the BM@N experiment at the Nuclotron/NICA complex are presented on {\pi}+ and K+ meson production in interactions of an argon beam with fixed targets of C, Al, Cu, Sn and Pb at 3.2 AGeV. Transverse momentum distributions, rapidity spectra and multiplicities of {\pi}+ and K+ mesons are measured. The results are compared with predictions of theoretical models and with other measurements at lower energies.Comment: 29 pages, 20 figure

Current capabilities of endoscopic diagnosis of non-muscle invasive bladder cancer

Abstract In recent years, there has been a steady increase in the incidence of bladder cancer (RMP) in our country. So, over the past ten years there has been an increase in the number of cases of primary diagnosis of RMP by more than 1.5 times, which corresponds to 77.1 cases per 100,000 population. At the same time, mortality in the first year for the same time period decreased from 22.4% in 2008 to 14.4% in 2019. In 75% of patients, this disease is diagnosed at an early stage (the tumor spreads to the muscle layer — non-muscle-invasive forms of RMP), which allows organ-preserving treatment. One of the factors influencing these indicators is the introduction of new diagnostic search methods into the routine of doctors. Such methods include: photodynamic and narrow-spectrum diagnostics when performing cystoscopy, as well as other methods of increasing the visualization of hidden tumors
