Abstract The October effect is known as a rapid and strong decrease in the signal amplitude of radio waves with very low frequency (VLF), reflected at the lowest edge of the ionosphere. This strong decrease can be observed only during the daytime. Al

“We've been together in sickness and in health, through the death of his mother, through the adoption of our children, through four long years of this legal battle,” Jason Morgan told reporters of himself and his partner, Chuck Swaggerty. “And

We propose a new concept for measuring the affinity between fields of academic research. The importance of interdisciplinary research has been increasingly emphasized in recent years. The degree of interdisciplinarity of a research article can be det

Overexpression of cyclooxygenase-2 (COX-2) is generally considered to promote tumorigenesis. To investigate a potential role of COX-2 in osteosarcoma, we overexpressed COX-2 in human osteosarcoma cells. Saos-2 cells deficient in COX-2 expression were

Sudden Stratospheric Warmings (SSW) and Elevated Stratopause (ES) events are atmospheric wave driven winter phenomena, which lead to significant changes in wind, temperatures and vertical mass transport, especially in stratospheric and mesospheric al

Radar waves with very low frequency (VLF) are reflected at the lower edge of the ionosphere, in the D-region. The D-region (60 - 90km) is influenced by the solar zenith angle and space weather from above as well as by dynamical and chemical processes

In autumn the prevailing wind in the middle atmosphere at mid and high latitudes changes from summer easterly to winter westerly. This process is not smooth but interrupted by the Hiccup of the fall transition with characteristics similar to a mini s

The seasonal variation of the daytime lower ionosphere, monitored using the propagation of Very Low Frequency (VLF) radio waves, shows an asymmetry when comparing the spring and autumn transitions. Considering the solar zenith angle variation, it can
