Starting with the hypothesis that quark and lepton mixings are identical at or near the GUT scale, we show that the large solar and atmospheric neutrino mixing angles together with the small reactor angle Ue3 can be understood purely as a result of renormalization group evolution provided the three neutrinos are quasi-degenerate and have same CP parity. It predicts the common Majorana mass for ...

Knowledge and control of mixing in batch processes can prevent yield losses during scale-up. Therefore, this study, a new heat-mixing model based ono the measurement heat distribution after an applied pulse, is proposed. The was developed to predict mesomixing support scale-up, scale-down, design optimisation reactors. proposed considers influences rotational speed, stirrer type, solvent, stirr...

The data from the various neutrino experiments indicate a bimaximal mixing among three neutrino generations. The atmospheric neutrino puzzle requires a near maximal mixing between a pair of neutrinos [1]. The solar neutrino puzzle has various possible solutions but the large angle MSW solution is favoured [2]. As the mass squared difference required for these two solutions differ by about few o...

This paper examines the limit points of continuous Z-cocycles defined on a minimal dynamical system and taking values in an abelian metrisable group. This is motivated by and applied to the study of classical exponential series X^-i^"'" 6+nx) t 0 show, in particular, that if 0 is a transcendental number with liminfe^ ||^|| < oo, then for each x chosen from a dense Gd subset of [0,1], these part...

Microfluidic systems present advantages and challenges relative to larger systems for performing chemical processes. They facilitate manipulation and analysis of small sample volumes and process parallelization within a small footprint. However, they generally suffer from inefficient mixing and low rates of interfacial mass transfer, due to the laminar flow and the long diffusive mixing times c...

We suggest moment estimators for the parameters of a continuous time GARCH(1,1) process based on equally spaced observations. Using the fact that the increments of the COGARCH(1,1) process are strongly mixing with exponential rate, we show that the resulting estimators are consistent and asymptotically normal. We investigate the empirical quality of our estimators in a simulation study based on...

Thermohaline mixing has recently been proposed to occur in low mass red giants, with large consequences for the chemical yields of low mass stars. We investigate the role of thermohaline mixing during the evolution of stars between 1M⊙ and 3M⊙, in comparison to other mixing processes acting in these stars. We confirm that thermohaline mixing has the potential to destroy most of the He which is ...

To facilitate progression from the lab to commercial applications, it will be necessary to develop simple, scalable methods to produce high quality graphene. Here we demonstrate the production of large quantities of defect-free graphene using a kitchen blender and household detergent. We have characterised the scaling of both graphene concentration and production rate with the mixing parameters...

[1] Estimates of the dissipation of subinertial currents due to bottom boundary layer drag at the eastern and western boundaries of the North Atlantic ocean, between 15 N and 60 N, are computed using data from the world’s largest archive of ocean current meter time series. We show from these data that a significant proportion of such loss in this region is due to dissipation at the western boun...
