A new experiment is presented for the measurement of single aerosol particle extinction efficiencies, Qext, combining cavity ring-down spectroscopy (CRDS, λ = 405 nm) with a Bessel beam trap (λ = 532 nm) in tandem with phase function (PF) measurements. This approach allows direct measurements of the changing optical cross sections of individual aerosol particles over indefinite time-frames faci...

The paper discusses the effect of stirrer and container rotation direction on mixing index (Ip). chaos theory is result an in-depth study various problems that cannot be answered by two previous major theories, namely quantum mechanics relativity. Effective flow area does not depend rapid stirring. This uses a with double stirrer, camera, programmable logic controller, tachometer, 6 A adapter, ...

Abstract. Large uncertainties remain when estimating the warming effects of ambient black carbon (BC) aerosols on climate. One key challenges in modeling radiative is predicting BC light absorption enhancement, which mainly determined by mass ratio (MR) non-BC coating material to population BC-containing aerosols. For same MR, recent research has found that enhancements are also controlled its ...

Abstract We report experimental and theoretical results of two symmetrical signals degenerate four-wave mixing generated in rubidium vapor. Both nonlinear are induced by almost copropagating laser beams, with ...

We present the first tests of a new method, the Correlated Component Analysis (CCA) based on second-order statistics, to estimate the mixing matrix, a key ingredient to separate astrophysical foregrounds superimposed to the Cosmic Microwave Background (CMB). In the present application, the mixing matrix is parameterized in terms of the spectral indices of Galactic synchrotron and thermal dust e...

For the A = 32, T = 2 quintet we provide a unified theoretical description for three related aspects of isospin mixing: the necessity of more than three terms in the isobaric mass multiplet equation, isospin-forbidden proton decay in 32Cl, and a correction to the allowed Fermi β+ decay of 32Ar. We demonstrate that all three effects observed in experiment can be traced to a common origin related...
