We believe that the trigger for a catastrophic explosion can be one of the earthquakes preceding the eruption, which resonates with self-oscillations in the peripheral chamber beneath the volcano. This greatly increases the power of the impulse and helps to overcome the energy barrier. It is ...
The mathematics of networks is a common language to describe the large-scale structure of vastly different systems throughout the natural, social, and formal sciences. From power grids to the neural system; from the narrative structure of novels to subway systems; from friendship contacts to money...
Copper-containing enzymes perform fundamental functions by activating dioxygen (O2) and therefore allowing chemical energy-transfer for aerobic metabolism. The copper-dependence of O2transport, metabolism and production of signalling molecules are supported by molecular systems that regulate and preserve tightl...
despite the decrease in global surface heat flux. A similar situation is found in the individual basins, though magnitudes differ.A conclusion is that natural variability
Copper-containing enzymes perform fundamental functions by activating dioxygen (O2) and therefore allowing chemical energy-transfer for aerobic metabolism. The copper-dependence of O2 transport, metabolism and production of signalling molecules are suppo
The causes of the nonuniqueness of the functions describing the frequency and amplitude of the resonant oscillations are analyzed; a generalized definition of the notion of instantaneous frequency is given which takes into account the character of the natural oscillations. Oscillatory systems with varying...
The general circulation of the oceans defines the average movement of seawater, which, like the atmosphere, follows a specific pattern. Superimposed on this pattern are oscillations of tides and waves, which are not considered part of the general circulation. There also are meanders and eddies that...
there are natural oscillations in Earth’s climate that alter global patterns of wind circulation,precipitation, and surface temperatures. One such phenomenon is theEl Niño/Southern Oscillation (ENSO), a coupled atmospheric and oceanic event that occurs in thePacific Oceanevery three to seven years...
hydraulic shocks (fluid hammer) causing the excitation of the safety system. According to [9], hydraulic shocks are the phenomenon of strong pressure oscillations in a pipe operating under pressure, caused by rapid changes in the velocity of the fluid flow in a short time. The hydraulic shocks...
