  The possibility of the validation of the 3+1 neutrino model is considered in
the context of the new result of the Neutrino-4 experiment, the direct
observation of the oscillation effect at parameter region $\Delta m_{14}^2=(7.3
\pm 0.13_{stat} \pm 1.16_{syst})\text{eV}^2$ and $\sin^2(2\theta_{14}) = 0.36
\pm 0.12_{stat} (2.9\sigma)$, also using LSND anomaly, MiniBooNE anomaly,
reactor antineutrino anomaly, and gallium anomaly observed in experiments with
radioactive sources GALLEX/GNO and SAGE. We analyze agreement of the neutrino
parameter values obtained in the Neutrino-4 experiment with the results of
other reactor type experiments NEOS, DANSS, STEREO, PROSPECT, the experiments
at accelerators MiniBooNE, LSND, and the IceCube experiment. We present the
analysis of the 3+1 neutrino model which demonstrates the agreement among the
experiments within current experimental accuracy. Also, current accuracy allows
us to make estimations of the effective masses of the neutrinos. The mass of
the sterile neutrino obtained in the Neutrino-4 experiment (in assumption
$m_2^2 \approx \Delta m_{14}^2$) is $m_4 = (2.70\pm0.22)\text{eV}$. Using the
estimations of the mixing angles we calculated the values of the electron, muon
and tau neutrinos: $m_{4\nu_e}^{\text{eff}}=(0.82\pm0.18)\text{eV},
m_{4\nu_{\mu}}^{\text{eff}}=(0.41\pm0.26)\text{eV},
m_{4\nu_{\tau}}^{\text{eff}}\leq 0.60\text{eV}$. These results are compared
with the values obtained in the experiments in the direct measurement of the
neutrino mass KATRIN and GERDA. The Pontecorvo-Maki-Nakagawa-Sakata matrix with
four states and the mixing scheme of the flavor neutrinos with the sterile
state are presented.
