Some results of studying the acoustics of dolphins

Acoustical Physics - An experimental study of the echolocation ability of dolphins (Tursiops truncatus) is performed in the presence of correlated and uncorrelated broadband noise acting on their...     

Self-stochasticity phenomenon in dynamical systems generated by difference equations with continuous argument

For dynamical systems generated by the difference equations x(t+1) = f(x(t)) with continuous time (f is a continuous mapping of an interval onto itself), we present a mathematical substantiation of the self-stochasticity phenomenon, according to which an attractor of a deterministic system contains random functions. __________ Translated from Ukrains’kyi Matematychnyi Zhurnal, Vol. 58, No. 7, pp. 954–975, July, 2006.     

Adiabatic population transfer in the three-level Λ-system: two-photon lineshape

We discuss the dependence of the population transfer probability in the three-level Λ-scheme using stimulated Raman adiabatic passage on detuning from the two-photon resonance. For a large decay rate of the intermediate level we found that the two-photon lineshape is close to Gaussian with linewidth inversely proportional to the square root of the decay rate. The shift of the maximum of the two-photon line from exact two-photon resonance has been investigated.     

Crystal structure of mixed-ligand complexes of the Ni(II) heterospin bischelate withiso-butyl alcohol and 1,4-Butanediol

The crystal structures of the mixed-ligand complexes of the heterospin bischelate bis [2,2,5,5-tetramethyl-l-oxyl-3-imidazoline-4-(3’,3’,3’-trifluoro-1’-propenyl-2’-oxiato)nickel(II) (NiL₂) with iso-butanol and 1,4-butanediol NiL₂(i-C₄H₉OH)₂ and NiL₂[HO(CH₂)₄OH], respectively, are determined. The crystal structure of the NiL₂ complex with the normal butyl alcohol NiL₂(n-C₄H₉OH)₂ and the structure of CoL₂[HO(CH₂)₄OH] are refined.
