Changes in the properties of the studied crystal phases were analyzed by using different approximations for exchange-correlation functional. The electronic properties of perovskites have been investigated by estimated their changes upon applying spin-orbit coupling. The electronic properties demonstrate that all crystal phases CsPbBr<inf>3</inf> and CH<inf>3</inf>NH<inf>3</inf>PbBr<inf>3</inf> are semiconductors with direct bandgaps. The optical properties exhibit that investigated perovskites have good photon absorption ability due to their value of bandgaps.

This research is devoted to solving the problem of classifying patients with diabetes and diagnosing this disease. To solve the problem, a machine learning model was built based on a modified k-nearest neighbors method. To develop the model, an open database of patients with diabetes, consisting of 768 patients, was used. The constructed model shows an accuracy of 89%.

The structures of the samples are deduced issuing from the ‘parent’ compounds $mathbf{Cd}_{16}mathbf{Te}_{15}$ and $mathbf{Cd}_{16}mathbf{Se}_{16}$. A cubic structure of the ‘parent’ compounds is taken. The bandgap of $mathbf{CdTe}_{1-x}mathbf{Se}_{x}$ is found to be of a direct type for all of the solid-state solutions under test. Basing on the electronic band structure, we obtain the effective electron mass, the effective masses of holes corresponding to different energy levels, and the reduced carrier mass at the $mathbf{G}$ point of Brillouin zone. The optical parameters such as exciton-binding energy, refractive index and high-frequency dielectric constant are calculated, too. The elastic properties such as the Young, shear and bulk modules are predicted, along with and the Poisson ratio. Using the data for the elastic coefficients, the acoustic velocities and the Debye temperature are obtained.
