We study systems with finite number of states $A_i$ ($i=1,..., n$), which obey the first order kinetics (master equation) without detailed balance. For any nonzero complex eigenvalue $lambda$ we prove the inequality $frac{|Im lambda |}{|Re lambda |} leq cotfrac{pi}{n}$. This bound is sharp and it becomes an equality for an eigenvalue of a simple irreversible cycle $A_1 to A_2 to... to A_n to A_1$ with equal rate constants of all transitions. Therefore, the simple cycle with the equal rate constants has the slowest decay of the oscillations among all first order kinetic systems with the same number of states.
We introduce a definition of gamma-ray burst (GRB) duty cycle that describes the GRBs efficiency as an emitter; it is the GRBs average flux relative to the peak flux. This GRB duty cycle is easily described in terms of measured BATSE parameters; it i
The fundamental issue in the energetic performance of power plants, working both as traditional fuel engines and as combined cycle turbine (gas-steam), lies in quantifying the internal irreversibilities which are associated with the working substance
Surface analyses inside the nanopore, micropore, and a very narrow pipe are important topics for development of the chemical engineering. Here, we propose a measuring method which evaluates the surface coverage of the chemically modified pore surface
We consider Sobolev mappings $fin W^{1,q}(Omega,IC)$, $1<q<infty$, between planar domains $Omegasubset IC$. We analyse the Radon-Riesz property for convex functionals of the form [fmapsto int_Omega Phi(|Df(z)|,J(z,f)) ; dz ] and show that under cer
A nonlinear interferometry scheme is described theoretically to induce and resolve electron wave- function beating on time scales shorter than the optical cycle of the time-delayed pump and probe pulses. By employing two moderately intense few-cycle
