In this paper, thermal mixing characteristics of two miscible fluids in a T-shaped microchannel are investigated theoretically, experimentally, and numerically. Thermal mixing processes in a T-shaped microchannel are divided into two zones, consisting of a T-junction and a mixing channel. An analytical two-dimensional model was first built to describe the heat transfer processes in the mixing c...

We describe a generalization of a recently-proposed two-phase ow model for the statistical evolution of an incompressible mixing layer. This model, which was originally developed for application to Rayleigh-Taylor mixing, predicts the distribution of volume fractions and uid velocities across the mixing layer in terms of the trajectories of the edges. Our previous analysis of this model is exte...

The implications of one gluon exchange generated configuration mixing in the Chiral Quark Model (χQMgcm) with SU(3) and axial U(1) symmetry breakings are discussed in the context of proton flavor and spin structure as well as the hyperon β-decay parameters. We find that χQMgcm with SU(3) symmetry breaking is able to give a satisfactory unified fit for spin and quark distribution functions, with...

[1] To reexamine the potential for lateral mixing over large distances (>100 km) by impact craters, a mathematical model utilizing the stable probability distribution is proposed for estimating lateral mixing efficiency on the Moon. The proposed model divides material mixing into shallow slope and steep slope regimes. Mixing in the shallow slope regime conforms to the condition that the exponen...

In the seesaw model with hierarchical Dirac masses, the neutrino mixing angle exhibits the behavior of a narrow resonance. In general, the angle is strongly suppressed, but it can be maximal for special parameter values. We delineate the small regions in which this happens, for the two flavor problem. On the other hand, the physical neutrino masses are hierarchical, in general, except in a larg...

VTEX is a (commercial) extended version of TEX, sold by MicroPress, Inc. Free versions of VTEX have recently been made available, that work under OS/2 and Linux. This paper describes GEX, a fast fully-integrated PostScript interpreter which functions as part of the VTEX code-generator. GEX offers one-pass compilation of text (TEX) and graphics and thus easy incorporations of graphics files (.ep...

We have obtained the neutrino mass matrix with the large mixing angle (LMA) MSW solution, sin 2θ⊙ = 0.65 ∼ 0.97 and ∆m⊙ = 10 −5 ∼ 10−4eV2, in the S3L × S3R flavor symmetry. The structure of our neutrino mass matrix is found to be stable against radiative corrections. The solar neutrino data as well as the atmospheric one give big impact on the study of the lepton mass matrices. There is a typic...

We investigate the effect of SUSY phases ( θA and θμ ) on the B 0 d−B 0 d mixing in the minimal supergravity model. It is known that the complex phase θA = arg(A) ( A is the universal coefficient of the trilinear scalar couplings ) is essentially unconstrained by the electric dipole moment experiment, while the phase θμ = arg(μ) ( μ is the supersymmetric Higgsino mass ) is strongly constrained ...

We prove that the noisy voter model mixes extremely fast – in time of O(logn) on any graph with n vertices – for arbitrarily small values of the ‘noise parameter’. We then explain why, as a result, this is an example of a spin system that is always in the ‘high-temperature regime’.

-Activity expressions are presented for a six end-member, regular solution, site-mixing model for chlorites. The end members are ideal 14-/~ chlorites for which experimental stability data are lacking. Estimates were made of the standard state 25~ and 1 bar molar 3rd law entropies, volumes, and the Maier-Kelley heat capacity coefficients. Experimental stability data from the literature for 14-A...
