* Correspondence: lym1019@163. com Department of Mathematics, Shangrao Normal University, Shangrao 334001, China Full list of author information is available at the end of the article Abstract Consider the semiparametric regression model Yi = xi b + g (ti) + εi, i = 1, . . . , n, where the linear process errors εi = ∑∞ j=−∞ ajei−j with ∑∞ j=−∞ ∣∣aj∣∣ < ∞ , and {ei} are identically distributed a...
We present preliminary results from Fermilab E791 on D 0 ? D 0 mixing and doubly Cabibbo-suppressed decays (DCSD) of the D 0 and D + mesons. The time dependence of the wrong-sign signal (D 0 ! K + ?) is used to establish separate limits on DCSD and mixing. From one third of our data we obtained r mix < 0:47%, r DCSD < 2:7% at the 90% conndence level.
Compartment models are widely used for evaluation of radiological consequences to man and biota in marine environment with spatial and temporal scales of several thousand kilometres and millenniums, respectively (EC, 2003). The compartment modelling uses two rigid general assumptions for dispersion of radionuclides in oceanic space: (a) uniform and (b) instantaneous mixing in each compartment. ...
The authors give easy-to-check sufficient conditions for the geometric ergodicity and the finiteness of the moments of a random process xt = φ(xt−1, . . . , xt−p)+ tσ(xt−1, . . . , xt−q) in which φ : IR → IR, σ : IR → IR and ( t) is a sequence of independent and identically distributed random variables. They deduce strong mixing properties for this class of nonlinear autoregressive models with ...
There are many computational models whose broad purpose is to allow an agent to learn via experience to perform effectively in a given environment. However, it is uncommon to see these models directly compared to each other, or to empirical data of real creatures adapting to their environments. Here, a comparison methodology is proposed involving various known results in classical and operant c...
The start up 
 dynamics of a one-million and two-hundred-thousand liter anaerobic digester of municipal waste treatment sludge was studied. In the digester, mixing was accomplished by circulation of the produced biogas at a rate of 0.13 m3 per hour of the digester volume per hour. During the nine-month study, no serious phenomena of foaming, getting sour, temperature fall, etc. were observe...

A viscosity model, based on Eyring’s absolute rate theory combined with a cubic PR equation of state and Wong-Sandler mixing rule, has been proposed in order to correlate viscosities of aqueous solutions of alkanolamine mixtures at atmospheric pressure and different temperatures. In the proposed method, the energy and size parameters in studied Equation of State (EoS) have been obtained usi...
We present a model for leptonic mixing and the lepton masses based on flavor symmetries and higher-dimensional mass operators. The model predicts bilarge leptonic mixing (i.e., the mixing angles θ12 and θ23 are large and the mixing angle θ13 is small) and an inverted hierarchical neutrino mass spectrum. Furthermore, it approximately yields the experimental hierarchical mass spectrum of the char...
In this study, the possibility of producing coal with less than 11% ash from tailings of flotation process was investigated. The effect of six flotation parameters: collector type, collector consumption, frother type, frother consumption, pulp density and mixing rate were studied on a sample from a tailing dam. A software based experimental design approach (DX7) was applied to determine and mod...
