In this paper the anomalous magnetic dipole moment ofmuon in the littlest Higgs （LH） model is studied at one-loop level. We discuss the dependence of the contributions on the global symmetry breaking scale f, mizing angles c` and , and the Higgs triplet vacuum expectation value v＇ in the electroweak precision data preferring ranges. We find that the LH model can give a relatively small, but non-negligible extra weak contribution to the muon anomalous magnetic moment and can reduce the deviation of △aμ from 2.6σ for the SM to 2.5σ for the LH model.

CMT uses the stream control transmission protocol＇s（SCTPs） multihoming feature to distribute data across multiple end-to-end paths in a multihomed SCTP association. As the disparity of multipaths, it is facing a great challenge to solve the disorder of the received data packets. To lighten the reordering degree and then to improve the throughput performance, we need to estimate the real-time paths＇ bandwidth and round trip time（RTT） as exactly as possible. In this paper, we use the extended vector（ext-vec） Kalman filter（KF） to predict the available bandwidth and RTT of each path simultaneously. Based on this, we propose a predictive path selection algorithm for CMT in SCTP. To simulate and compare the algorithms＇ performance, two kinds of scenarios, bandwidth sensitive scenario and time and bandwidth sensitive scenario, are built and NS-2 is used. The simulation results show that the path selection algorithm can lessen the data packets disordering by correctly predicting each path＇s bandwidth and RTT in real time. Comparing the existing algorithms, the algorithm can converge more quickly and can improve the system total throughput in a certain extent in bandwidth sensitive scenario. To time and bandwidth sensitive scenario, it can greatly improve the convergence speed and total throughput.

Rapid hypoeutectic growth from a highly undercooled liquid was accomplished by containerless processing Ni-32%Sb hypoeutectic alloy in a 3m drop tube. The containerless state during the free fall of the droplet produces substantial undercooling up to 350K (0.24TL). The growth mechanism is found to transform from primary α-Ni dendrite plus lamellar eutectic to lamellar eutectic and finally to anomalous eutectic if droplet undercooling exceeds the two thresholds of 112K and 242K, respectively. Based on the current eutectic and dendritic growth models, the eutectic coupled zone is calculated and used to explain the growth mechanism transition. Calculations also indicate that the growth of α-Ni primary dendrite was mainly controlled by solute diffusion.

Let G（V, E） be a graph. A k-adjacent vertex-distinguishing equatable edge coloring of G, k-AVEEC for short, is a proper edge coloring f if （1） C（u）≠C（v） for uv ∈ E（G）, where C（u） = {f（uv）｜uv ∈ E}, and （2） for any i, j = 1, 2,… k, we have ｜｜Ei｜｜Ej｜｜ ≤ 1, where Ei = {e｜e ∈ E（G） and f（e） = i}. χáve （G） = min{k｜ there exists a k-AVEEC of G} is called the adjacent vertex-distinguishing equitable edge chromatic number of G. In this paper, we obtain the χ áve （G） of some special graphs and present a conjecture.

It is well-known that a close link exists between soil-water retention curve(SWRC)and pore size distribution(PSD).Theoretically,mercury intrusion porosimetry(MIP)test simulates a soil drying path and the test results can be used to deduce the SWRC(termed SWRCMIP).However,SWRCMIP does not include the effect of volume change,compared with the conventional SWRC that is directly determined by suction measurement or suction control *** deformable soils,there is a significant difference between conventional SWRC and *** this study,drying test was carried out on a reconstituted silty soil,and the volume change,suction,and PSD were measured on samples with different water *** change in the deduced SWRCMIP and its relationship with the conventional SWRC were *** results showed that the volume change of soil is the main reason accounting for the difference between conventional SWRC and *** on the test results,a transformation model was then proposed for conventional SWRC and SWRCMIP,for which the soil state with no volume change is taken as a *** between the experimental and predicted SWRCs showed that the proposed model can well consider the influence of soil volume change on its water retention property.
