In this paper we compute the radiation of the massless closed string states due to the non-vanishing coupling to the rolling open string tachyon with co-dimensions larger than 3, and discuss the effect of back reaction to the motion of the rolling tachyon. We find that for small string coupling, the tachyonic matters remain in the late time, but it will completely evaporate away over a string s...

The light quarks inside B mesons are usually treated as spectators and do not affect the decay rates which are assumed to be purely due to b quark decays. In this paper we calculate the non-spectator contributions to inclusive charmless B decays due to the spectator effects. We find that the non-spectator contributions to the branching ratio for B̄ are small (< 2 × 10), but the contributions to ...

In the decay of Υ(4S), the decay time distribution of Υ(4S) → f + X, where f is a final state that both B and B 0 can decay to, is the sum of the decay time distributions of B → f and B → f . Using this general rule, we estimate the sensitivity of single lepton CP violation measurements with respect to that of traditional di-lepton measurements. We find that the sensitivity of the single lepton...

The present study was aimed to observe the postthaw quality of Nili-Ravi buffalo bull semen cryopreserved during heat stress (hot summer months) and normal climatic conditions (fall, winter, spring months). For this purpose, four (n = 4) adult regular donor bulls were selected collect cryopreserve their throughout period an entire year. cryopreservation done following standard freezing protocol...

this study aimed to examine the relationship between pigments and seed fall rate of iranian castor genotypes and genetic diversity, specifically 28 castor genotypes (27 native and 1 modified), a randomized complete block design with three replications was conducted in 2014 and 2015 at the research farm of islamic azad university in damghan, northern iran. during the growth period, the following...

A novel method for calculation of the motion and radiation reaction for the two-body problem (body plus particle, the small parameter m/M being the ratio of the masses) is presented. In the background curvature given by the Schwarzschild geometry rippled by gravita-tional waves, the geodesic equations insure the presence of radiation reaction also for high velocities and strong field. The metho...

We estimate the sensitivity of single lepton CP violation measurements with respect to that of traditional di-lepton measurements. We find that the sensitivity of the single lepton method is better than that of the di-lepton method. The achievable sensitivity with the currently available data is already in the range relevant to standard model predictions. We also give general expressions for in...

S. Cowell Theoretical Division, Los Alamos National Laboratory, Los Alamos, New Mexico, 87545, USA (Dated: December 6, 2005) The modern theory of neutrinoless double beta decay includes a scaling factor that has often been treated inconsistently in the literature. The nuclear contribution to the decay half life can be suppressed by 15-20% when scaling factors are mismatched. Correspondingly, 〈m...

Although the concepts of systems change and sustainability are not new, little is known about the factors associated with systems change sustaining multi-state, multi-level fall prevention efforts. This exploratory study focuses on three State Departments of Health (DOH) that were awarded 5-year funding from the Centers for Disease Control and Prevention to simultaneously implement four separat...
