By decomposing a linearly polarized light field in terms of plane waves, the elliptic intensity distribution across the focal spot is shown to be determined by the E-vector's longitudinal component. Considering that the Poynting vector's projection onto the optical axis (power flux) is independent of the E-vector's longitudinal component, the power flux cross section has a circular form. Using ...

In the past years considerable attention has been devoted to designing and controlling patterns at the microscale using bottom-up self-assembling techniques. The precipitation process proved itself to be a good candidate for building complex structures. Therefore, the techniques and ideas to control the precipitation processes in space and in time play an important role. We present here a simpl...

Dynamic predictors of job-search intensity over time are examined in a large 10-wave longitudinal study of unemployed individuals. Two sets of variables relevant to the examination of job search from a dynamic, self-regulatory perspective--core self-evaluations (T. A. Judge, A. Erez, & J. E. Bono, 1998) and the theory of planned behavior (I. Ajzen, 1991)--were used to guide our examination. Res...

We show that cosmic-ray observations set a model-independent upper bound of En Fn,2 310 GeV/cm s sr to the intensity of high-energy neutrinos produced by photo-meson ~or p-p! interactions in sources of size not much larger than the proton photo-meson ~or p-p! mean-free-path. This bound applies, in particular, to neutrino production by either AGN jets or GRBs. The upper limit is two orders of ma...

to the amount of root growth under the various conditions. At the termination of the experiment nearly all the nematodes were found within the tomato roots. T h e numbers found outside the root were somewhat greater at low light intensity than at high light intensity, particularly at the high inoculum level. Roots produced at the low light intensity were probably insufficient to support the hig...

Individuals differ in the intensity of exercise they prefer and the intensity they can tolerate. The purpose of this project was to develop a measure of individual differences in the preference for and tolerance of exercise intensity. The steps involved in (a) item generation and face validation, (b) exploratory factor analysis and item selection, (c) structural validation, (d) examination of t...

static properties, relatively intensity noise and intensity modulation response in quantum cascade lasers (qcls) studied theoretically in this paper. the present rate equations model consists of three equations for the electrons density in the conduction band and one equation for photons density in cavity length. two equations were derived to calculate the noise and modulation response. calcula...
