Cilia are widely employed by living systems to manipulate fluid flow in various functions, such as feeding, pumping, and locomotion. Mimicking the intricate ciliary asymmetry combination with collective metachronal beating may find wide application transport mixing microfluidic systems. Here, we numerically analyze of pneumatic artificial cilia. We specifically address three aspects motion: (i)...

We consider a pattern of neutrino masses in which there is an approximate mass degeneracy between the two mass eigenstates most coupled to the ν µ and ν τ flavour eigenstates. Earth-matter effects can lift this degeneracy and induce an effectively maximal mixing between these two generations. This occurs if ν e 's contain comparable admixtures of the degenerate eigenstates, even rather small on...

We consider a pattern of neutrino masses in which there is an approximate mass degeneracy between the two mass eigenstates most coupled to the nm and nt flavor eigenstates. Earth-matter effects can lift this degeneracy and induce an effectively maximal mixing between these two generations. This occurs if ne’s contain comparable admixtures of the degenerate eigenstates, even if they are not larg...

We consider n observations from the GARCH-type model: S = σ2Z, where σ2 and Z are independent random variables. We develop a new wavelet linear estimator of the unknown density of σ2 under four different dependence structures: the strong mixing case, the β- mixing case, the pairwise positive quadrant case and the ρ-mixing case. Its asymptotic mean integrated squared error properties are ...

We discuss the lepton sector of a realistic string-inspired model based on the Pati-Salam SU(4) × SU(2) L × SU(2) R gauge group supplemented by a U(1) family symmetry. The model involves third family Yukawa unification, predicts large tan β ∼ 50, and describes all fermion masses and mixing angles, including approximate bi-maximal mixing in the neutrino sector. Atmospheric neutrino mixing is ach...

The velocity and mixing field of two coaxial jet configurations has been experimentally characterized by means of hotand cold-wire anemometry to investigate the effect of the initial conditions on the flow development, and to determine the leading processes in the “mixing transition” of the two streams. Amongst the possible operating conditions, four configurations with different inner and oute...

the mixing behavior of the gas-liquid phase in three loop bioreactors was investigated. a gas-induced external airlift loop bioreactor (ealb), a forced-liquid vertical tubular loop bioreactor (vtlb) and a forced-liquid horizontal tubular loop bioreactor (htlb) were used for mixing studies as well as biomass production from natural gas. the effect of design parameters, riser to downcomer cross s...

The apparent persistence of symmetry in the face of strong symmetry-breaking interactions is examined in a many-boson model. The model exhibits a transition between two phases associated with U(5) and O(6) symmetries, respectively, as the value of a control parameter progresses from 0 to 1. The remarkable fact is that, in spite of strong mixing of the symmetries for intermediate values of the c...

The formalism underlying the analysis of e + e − → π + π − in the ρ − ω interference region is carefully revisited. We show that the standard neglect of the pure I = 0 omega, ω I , " direct " coupling to ππ is not valid, and extract those combinations of the direct coupling and ρ-ω mixing allowed by experiment. The latter is shown to be only very weakly constrained by experiment , and we conclu...
