We consider Lie(G)-valued G-invariant connections on bundles over spaces G/H , R×G/H and R2×G/H , where G/H is a compact nearly Kähler six-dimensional homogeneous space, and the manifolds R×G/H and R2×G/H carry G2and Spin(7)-structures, respectively. By making a G-invariant ansatz, Yang-Mills theory with torsion on R×G/H is reduced to Newtonian mechanics of a particle moving in a plane with a q...

The Chern-Simons level k of ABJM gauge theory captures the orbifolding in the dual geometry. This suggests that if we move the membranes away from the tip of the orbifold to a smooth point, it should trigger an RG flow that changes the level to k = 1. We construct an explicit supergravity solution that is dual to this shift from generic k to k = 1. In the gauge theory side, we present arguments...

We investigate the relative informativeness of earnings and dividends for firms with dual class capital structures. In these firms, two classes of common stock create a separation between cash flow rights and voting rights. Despite the concentrated ownership in the dual class firms, we find significantly lower informativeness of earnings, in the form of a weaker returns-earnings association, th...

Abstract Photoacoustic Doppler flow measurement based on continuous wave laser excitation owns the merit of clearly presenting power spectra. Extending this technique to dual wavelengths can gain spectral information sample extra speed information. An experimental system with two diodes respectively operated at 405 nm and 660 is built black red dyed polystyrene beads performed. The measured spe...
