The formation of femtosecond pulsed laser-induced periodic surface structure on GaN is reported for the first time (to our knowledge) in this paper. It has been found that the formation of the laser-induced ripples is very much dependent and quite sensitive to the laser conditions of the...

This paper applies an unobserved components model to a panel of Australian data to identify the direction and timing of the shifts in regional Beveridge curves. The approach identifies a...

A general parametric framework based on the generalized Student t-distribution is developed for pricing S&P500 options. Higher order moments in stock returns as well as time-varying volatility are priced. An important computational advantage of the proposed framework over Monte Carlo-based...
