“Oscillating” Metallocene Catalysts: How Do They Oscillate?
Angewandte Chemie International Edition, 2002Based on the results of a series of propylene polymns. using oscillating metallocene catalysts of type [(2-Ar-indenyl)2ZrCl2] (Ar = C6H5 or 3,5-(t-Bu)2-4-MeO-C6H2) with various cocatalysts (MAO, TIBAl), the oscillating behavior of the zirconocenes is discussed with respect to the rac/meso stereochem. outcome of the obtained polypropylenes.

Forced oscillations in oscillator circuits, and the synchronization of oscillators
Journal of the Institution of Electrical Engineers - Part III: Radio and Communication Engineering, 1945The behaviour of a feedback oscillator circuit under the influence of an injected tone having a frequency close to the natural frequency of oscillation is considered from the point of view of the steady-state equilibrium of the loop transmission circuit.

Oscillation frequency in CML and ESCL ring oscillators
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2001In this paper a model to accurately evaluate even in a pencil-and-paper manner the oscillation frequency of a ring oscillator made up by a CML or ESCL differential gate is proposed. The model allows us to simply estimate the oscillation frequency changes due both to the bias current change and to process tolerances.

Simultaneous Oscillations in Oscillators
Transactions of the IRE Professional Group on Circuit Theory, 1954An oscillator with two degrees of freedom can, under certain conditions, oscillate simultaneously at two different frequencies. The ratio of the two frequencies may be rational (synchronous oscillations) or irrational (asynchronous oscillations). The conditions necessary for 'simultaneous oscillations are discussed for these two cases.

The wave theory of light, and in particular the principle of interference, was formulated by Thomas Young in 1801. In the 20th century, the principle of interference was extended to the quantum mechanical wave functions describing matter. The phenomenon of quantum mechanical interference of different neutrino states, neutrino oscillations, has provided
