We present measurements of time-dependent asymmetries in decays of neutral B mesons to the final states B 0 → ρ ± π ∓. Measurements are based on a 140 f b −1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e + e − collider.

We have solved Cosmological Gravitational Wave(GW) equation in the frame work of Gen-eralised Brans-Dicke(GBD) theory for all epochs of the Universe.The solutions are expresed in terms of the present value of the Brans-Dicke coupling parameter ω(φ).It is seen that the solutions represent travelling growing modes for negative values of ω 0 for all epochs of the Universe.

In this note, we prove that the ∂and ∂̄-operators introduced by Gualtieri for a generalized complex structure coincide with the d̆∗and ∂̆-operators introduced by Alekseev-Xu for Evens-Lu-Weinstein modules of a Lie bialgebroid.
