Cross-shore sediment transport rate exposed to waves is very important for coastal morphology, the design of marine structures such as seawalls, jetties, breakwaters etc, and the prevention of coastal erosion and accretion due to onoff shore sediment transportation. in the present study, the experiments on cross-shore sediment transport are carried out in a laboratory wave channel with initial beach slopes of 1/8, 1/10 and 1/15. By using the regular waves with different deep-water wave steepnesses generated by a pedal-type wave generator, the geometrical characteristics of beach profiles under storm conditions and the parameters affecting on-off shore sediment transport are investigated for the beach materials with medium diameters of d50=0.25, 0.32, 0.45, 0.62 and 0.80 mm. The offshore bar geometric characteristics are the horizontal distances from the shoreline to the bar beginning （Xb）, crest （Xt）, and ending （Xs） points, the depth from the bar crest to the still water level （ht）, and the bar volume （Vbar）. The experimental results have indicated that when the deep-water steepness （ha/L0） increased, the net movement to seaside increased. With the increasing wave steepness, the bars moved to widen herewith the vertical distances from still water level to the bar beginning （Xb）, crest （Xt） and ending （Xs） points and the horizontal distances from the coast line to the bar beginning, crest and ending points increased. it was also shown from experimental results that the horizontal distances from the bar beginning and ending points to the coast line increased with the decrease of the beach slope. The experimental results obtained from this study are compared with previous experimental work and found to be of the same magnitude as the experimental measurements and followed the expected basic trend.

Bi_(2)Te_(3)基合金因其优异的电输运性能和较低热导率在低温区热电材料中备受关注。然而由Bi_(2)Te_(3)基合金制造的热电发电或制冷器件转化效率仍较低,因此进一步提升Bi_(2)Te_(3)基材料的热电优值zT是关键。由于晶格热导率与电性能参数关联较少,在热电性能参数中较为独立,因此,在不影响电性能的前提下,通过声子工程降低晶格热导率成为提升zT值的重要方法。本文主要综述了近年来通过纳米改性、超晶格结构、纳米复合、掺杂和引入位错阵列等声子工程优化Bi_(2)Te_(3)基材料热电性能的主要研究进展。通过这些优化手段可以显著降低材料的比热容、声子群速度或声子平均自由程,Bi_(2)Te_(3)基材料的晶格热导率显著降低,热电性能大幅提升,为热电器件的应用提供科学和技术支撑。

background: While working as risk consultants at barra in 1990’s, the first two authors decided to start collaborating on a research project with its first paper titled “Application of Volatility in Portfolio Construction” [1]. The third author was then a risk manager of a financial institution which was a client of barra’s. Bringing his expertise in portfolio risk management, he joined the research team. Aim: The core of this paper lies in the construction of an investment portfolio with a main objective of value appreciation while examining its tracking error [1]-[3], a risk measurement with reference to a benchmark [1] [4]. The authors believe, while tracking error measurement is a common tool for portfolio risk management, total risk measurement is more important. The management goal is to minimize drawbacks using the technique of risk budgeting. These topics will be discussed in future research papers.

A measurement of the z production cross-section in γe^(-) collisions at the Large hadron^(-)electron Collider(LHeC) is presented for comparison to that at the international Linear Collider(iLC).The total cross-section depends strongly on the polarization of the initial and final e^(-)beams and the electron beam energy Ee;the energy of the proton beam was set to E_(p)=7 *** results show that the total cross^(-)section in γe^(-)→ze^(-)→l^(-)l+e^(-) at the LHeC is much larger than that at the iLC.
