The modified Chaplygin gas (MCG) as an interacting model of holographic dark energy in which dark energy and dark matter are coupled together is investigated in this paper. Concretely, by studying the evolutions of related cosmological quantities such as density parameter Ω, equation of state w, deceleration parameter q and transition redshift zT, we find the evolution of the universe is from deceleration to acceleration, their present values are consistent with the latest observations, and the equation of state of holographic dark energy can cross the phantom divide w = -1. Furthermore, we put emphasis upon the geometrical diagnostics for our model, i.e., the statefinder and Om diagnostics. By illustrating the evolutionary trajectories in r - s, r - q, w -w and Om planes, we find that the holographic constant c and the coupling constant b play very important roles in the holographic dark energy (HDE) model. In addition, we also plot the LCDM horizontal lines in Om diagrams, and show the discrimination between the HDE and LCDM models.

The new particles predicted by the littlest Higgs model with T-parity (called LHT model) can induce the lepton flavor violation (LFV) couplings at the one-loop level,which can add contributions to some LFV *** into account the constraints of the experimental data on the relevant free parameters,we calculate the branching ratios of the LFV decay processes Z → l ˉl and τ-→μ-P 1 P 2 with P 1 P 2 = π + π-,K + K-,and K0 ˉK 0 in the context of this new physics *** find that the LHT model can indeed make significant contributions to some of these LFV decay *** Z factory option for the future high energy e + e-collider experiments will give severe constraints on the LHT model.

In the context of the littlest Higgs (LH) model, we estimatc the production cross section of the process e~-γ→e~-H in the future high-energy linear e~+e~- collider (IL C) with the center-of-mass (CM) energy S=500 *** numerical results show that the contributions of the LH model to this process are very small in most of the parameter space allowed by the electroweak precision measurement data, and are very difficult to be detected in the future ILC experiments.

ABEEM/MM model has been applied to compute the various properties characterizing water clusters(H2O) n(n = 7-10) ,such as optimized geometries,the hydrogen bonds number,cluster interaction en-ergies,stabilities,ABEEM charge distributions,dipole moments,structural parameters,and so on,and to describe the transition reflected by the hexamer region from two-dimensional(from dimer to pen-tamer) to three-dimensional structures(for clusters larger than the hexamer) .

We have performed molecular dynamics simulations on the reversible folding/unfolding of small α-helix(short Ala based peptide Ala5) in explicit water solvent in terms of ABEEMσπ/MM.A dynamics analysis shows that the α-helical turn can be preserved up to a period of about 2 ns at 3.0 K,which supports the conclusions of Margulis et *** time trajectory of the root mean square deviation between the heavy atoms of the backbone and the helical reference structure indicate that "helix melting and formation occurs rapidly on a time scale of 0.1 ns at 3.0 K" is not a felicitous *** first quantificationally concluded that the helix nucleation can maintain 2 ns,1―1.5 ns and 0.8 ns for Ala5 at 3.0 K,400 K and 500 K,***,increasing temperature dose not alter the pathway of folding/unfolding,but change the *** analysis of structures in a "transition-state ensemble" shows that helix-to-coil transitions occurs predominantly through breaking of hydrogen bonds at the helix ends(92%),particularly at the C-terminus(50%).Hydrogen bonds' breaking and formation occurs on a time scale of 0.1 ns.

Non-relativistic energies of 1s22s and 1s2np (n≤9) states for Co24+ ion are calculated by using the full-core plus correlation method. Our results of 1s22s and 1s22p states agree well with the high-precision results of Yan et al. Based on calculating the first-order corrections to the energy from relativistic and mass-polarization effects,we estimate the higher-order relativistic contribution and QED correc-tion to the energy under a hydrogenic approximation. The transition energies,wavelengths and oscil-lator strengths for the 1s22s-1s2np (n≤9) transitions of this ion are calculated. The results agree with the experimental data available in literature satisfactorily. By combining with quantum defect theory,our theoretical predictions on the energy and oscillator strength of this ion are extrapolated to the whole energy region including continuous states.
