Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Connection of total electron content disturbances with AE index of geomagnetic activity during geomagnetic storm in March 2015

open access: yesSolar-Terrestrial Physics, 2022
Ionospheric response to the March 17, 2015 geomagnetic storm has been investigated using simulations of the Global Self-consistent Model of the Thermosphere, Ionosphere, Protonosphere (GSM TIP) [Dmitriev et al., 2017; Klimenko et al., 2018].

Relationships between geomagnetic Ар-indeх and EEG parameters in patients with dysfunction of the neuroendocrine-immune complex

open access: yesJournal of Education, Health and Sport, 2021
Background. Recently, on the example of two cohort of patients, we found that disturbances of the geomagnetic field cause a significant immediate modulating effect on the level of immune parameters in the blood. The data available in the literature give

A NEURAL NETWORK SYSTEM FOR ESTIMATION OF THE GEOMAGNETIC FIELD DISTURBANCE [PDF]

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2016
The paper presents our software system for estimation the degree of disturbance of the geomagnetic field. The system automatically classifies registered geomagnetic data and determines the state of the geomagnetic field for the current day.
