A family of high-order accuracy explict difference schemes for solving 3-dimension parabolic P. D. E. is constructed. The stability condition is r = Deltat/Deltax(2) Deltat/Deltay(2) = Deltat/Deltaz(2) t(2) + Deltax(4)).

Artificial neural network(ANN) models have been employed to the calculations ofdensities and excess molar volumes of water+methanol+ethylene glycol ternary system at different temperatures. The results were satisfactory comparing with the experimental values. The method wasconvenient in operation, rapid in calculation and easy in extending to multicomponent systems.

Based on the littlest Higgs model, we investigate the spin correlation of the top quark pair production via the process e^＋e^- →tt at the high energy linear e^＋e^- collider （ILC） with a centre-of-mass energy √S = 800 GeV. Our numerical results show that the gauge boson ZH generates very small corrections to the spin correlation observable C in all the parameter space allowed by the electroweak data. However, with reasonable values of the free parameters, the value of the relative correction parameter RBH = （CBH-CSM）/CSM can reach 10%, which might be detected in future ILC experiments.

The construction of the biproduct of Hopf algebras, which consists of smash product and the dual notion of smash coproduct, was first formulated by Radford. In this paper we study the quasitriangular structures over biproduct Hopf algebras B*H. We show the necessary and sufficient conditions for biproduct Hopf algebras to be quasitriangular. For the case when they are, we determine completely the unique formula of the quasitriangular structures. And so we find a way to construct solutions of the Yang-Baxter equation over biproduct Hopf algebras in the sense of (Majid, 1990).

The additivity rule has been employed to calculate the total cross sections for electron scattering by CF4,CFaH, CF2H2, and CFH3 molecules over an incident energy range from 100 to 3000 eV. Compared with other calculations and experimental data for CF4, excellent agreement has been obtained. Above 1000 eV, there are no experimental data for CF3H, CF2H2, and CFH3, so the present results can provide comparison and prediction for experimental research.

According to the recent experimental data, the time-dependent CP asymmetry SφKs for Ba → CKs decay might still be inconsistent with the standard model （SM） expectations. We try to understand the anomaly with a Z＇ model associated with flavour changing neutral currents （FCNCs） at the tree level. We find that （i） if neglecting the contributions from the right-handed flavour changing coupling Bsb^R and setting ξ^LL = ξ^LR =ξ and ξ^LL = ξ, ξ^LR = 0, we may obtain 0.01 〈ξ 〈 0.014, 0.0175 〈ξ〈 0.0205, 0.021 〈 ξ 〈 0.0255 and 0.004 〈 ξ 〈 0.008, 0.018 〈ξ 〈 0.028, 0.042 〈ξ〈 0.048 for the Bd → φKs decay, respectively; （ii） if considering the contributions coming from Bsb^R and setting ξ^LL = ξ^RL= ξ^LR = ξ,ξ^LR =ξ^RR=0, we can obtain 0.005 〈 ξ 〈 0.075, 0.0085 〈 ξ 〈 0.0105, 0.011 〈 ξ 〈 0.013 and 0.0125 〈 ξ 〈 0.0177, 0.0224 〈 ξ 〈 0.025. These results are consistent with the constraints and the assumptions in some literature.

The dominant decay modes of charged top-pions (πt^± ) are t-↑b or -↑tb. We consider the single production of charged top-pions in association with a top quark via e^+e^- annihilation and calculate the production cross section of the processes e^+e^- → -↑tbπ^+ (t-↑bπ^-) at the leading order. We find that it can reach 1.2 fb with reasonable parameter *** charged top-pions may be detected via the channel tbπ^± in the future high energy e^+e^- colliders.
