Elimination of the chirp of optical pulses through cascaded nonlinearities in periodically poled lithium niobate waveguides

open access: yes, 2010
We propose and demonstrate a novel method for the elimination of arbitrary frequency chirp from short optical pulses. The technique is based on the combination of two cascaded second-order nonlinearities in two individual periodically poled lithium ...

Phase Transitions in One-dimensional Translation Invariant Systems: a Ruelle Operator Approach.

open access: yes, 2016
We consider a family of potentials f, derived from the Hofbauer poten-tials, on the symbolic space Ω = {0, 1}N and the shift mapping σ acting on it. A Ruelle operator framework is employed to show there is a phase transition when the temperature varies ...

Accurate computation of multi-dimensional Riesz potentials

open access: yes
The paper discusses a fast method for computing the Riesz potentials in the framework of the method approximate approximations. By combining high-order cubature formulas with tensor product approximations, we derive an approximation of the potentials ...

The Study on Prediction of Oxidative Decomposition Potential by Comparison between Simulation and Electrochemical Methods to Develop the Binder for High-voltage Lithium-ion Batteries

open access: yes, 2013
: As the development of available binder in the harsh conditions is needed, we propose the proper binder for high-voltage lithium-ion secondary batteries based on the quantum chem-istry modeling. The optimized structures, HOMO (Highest Occupied Molecular

Quantitative electronprobe microanalysis of rock-forming minerals

open access: yes, 1969
A number of well-characterized silicate minerals and metal oxides have been analysed by the electron-probe technique in two different instruments with a range of accelerating poten-tials.
