One of the simplest organosulfur reactions, that between ground state carbon atoms, C(P j), and hydrogen sulfide, H2S(X A1), was studied at an average collision energy of 21.0 kJ mol 21 using the crossed molecular beams technique. The product angular distribution and time-of-flight spectra of m/e545 (HCS) were monitored. Forward-convolution fitting of our data yields an almost isotropic center-...

We report quantitative relations between corruption level and economic factors, such as country wealth and foreign investment per capita, which are characterized by a power law spanning multiple scales of wealth and investment per capita. These relations hold for diverse countries, and also remain stable over different time periods. We also observe a negative correlation between level of corrup...

In this paper we analyze asset returns models with diffusion part and jumps in returns with stochastic volatility either from diffusion or pure jump part. We consider different specifications for the pure jump part including compound Poisson, Variance Gamma and Levy α-stable jumps. Monte Carlo Markov chain algorithm is constructed to estimate models with latent Variance Gamma and Levy α−stable ...

A method is presented for the stress analysis of flight vehicles under different flight conditions including gust and control surface deflection (or maneuver) using the governing equations of rigid-body motions and elastic deformations. The Lagrangian approach is used to derive the governing equations of motions. For this purpose, the basic equations of motions are derived in terms of potential...

In this work, I seek to model swarms of fruit flies, drosophila melanogaster, whose flights are characterized by straight flight segments interrupted by rapid turns called saccades. These flights are reminiscent of Levy-distributed randomwalks which are known to lead to efficient search behavior. I build two types of model for swarms of foraging fruit flies, whose behavior depends on swarm dens...

In this article we obtain the first passage time distribution of α-stable Levy processes. We derive moment estimators parameters α-inverse Gaussian laws and also their asymptotic distribution.
