This paper investigates the social-aware cooperation(SAC) among mobile terminals(MTs), motivated by the fact that modern smart devices have much improved context awareness. Aware of the social ties, the cooperative network contains two layers of property: social and physical. In order to observe how the social awareness benefit the cooperation performance, we first formulate the social ties between MTs into parameters that can describe the cooperative behaviors by taking the mobility feature into account, defined as the conviction-approval-suspicion(CAS) model. Limited by the processing capability, partner selection is of great practical significance. To this end, the social-aware partner selection strategy is analyzed, and a significant superiority is observed compared to social-unaware selection. By analyzing the cooperative throughput, an explicit relationship between the degrees-of-freedom gain and the social-physical property is finally derived. Simulation results validate the theoretical analysis.

Deepwater/deep-marine turbidite lobes are the most distal part of a siliciclastic depositional system and hold the largest sediment accumulation on the seafloor. As many giant hydrocarbon provinces have been discovered within deepwater lobe deposits, they represent one of the most promising exploration targets for hydrocarbon industry. Deepwater exploration is characterized by high cost, high risk but insufficient data because of the deep/ultra–deepwater depth. A thorough understanding of the deepwater turbidite lobe architecture, hierarchy, stacking pattern and internal facies distribution is thus vital. Recently, detailed outcrop characterizations and high–resolution seismic studies have both revealed that the deepwater lobe deposits are characterized into four–fold hierarchical arrangements from ＂beds＂, to ＂lobe elements＂, to ＂lobes＂ and to ＂lobe complex＂. Quantitative compilations have shown that hierarchical components of lobe deposits have similar length to width ratios but different width to thickness ratios depending on different turbidite systems. At all hierarchical scales, sand–prone hierarchical lobe units are always separated by mud–prone bounding units except when the bounding units are eroded by their overlying lobe units thus giving rise to vertical amalgamation and connectivity. Amalgamations often occur at more proximal regions suggesting high flow energy. A mixed flow behavior may occur towards more distal regions, resulting in deposition of ＂hybrid event beds＂. These synthesized findings could（1） help understand the lobe reservoir distribution and compartmentalization therefore benefit the exploration and development of turbidite lobes within the deep marine basins（e.g. South China Sea） and（2） provide rules and quantitative constraints on reservoir modeling. In addition, the findings associated with deepwater turbidite lobes might be a good starting point to understand the sedimentology, architecture and hierarchy of turbidites in deep lacustrine environment.

In this paper, an underwater structure is modeled as a cylindrical shell with internal bulkheads, and closed by a truncated conical shell, and it consists of metal substrate and sound absorbing coating, whose FGM core is considered. Suppose the inner cavity and outer space of the structure are filled with air and fluid mediums, the mechanical response of the underwater structure is calculated with Galerkin method while the acoustic response is investigated by means of the Helmholtz integral. Some numerical examples are given and the effect of geometrical size and material parameters on mechanical and acoustic response is discussed.

随着现代科技的迅猛发展,航空航天、军事工业及医疗卫生等重要领域要求器件高速化、智能化及小型化,而传统的形状记忆合金材料已满足不了现代科技的发展要求。研究者们对形状记忆合金的加工工艺和结构不断进行改进,发现Cu基和Fe基记忆合金存在马氏体热稳定性差、超弹性和形状记忆效应差、强度及硬度低、抗腐蚀性能差等严重问题,阻碍了其应用发展。纳米晶NiTi形状记忆合金制备高阻尼、高强度及耐腐蚀性材料自进入人们的视野以来,就得到了广泛关注。因此,纳米晶NiTi基形状记忆合金有望成为未来功能材料领域的重要研究对象。纳米晶NiTi形状记忆合金由于具有比粗晶和超细晶更高的硬度、抗拉强度及更大的可回复应变等特性而得到广泛关注。然而,NiTi形状记忆合金的诸多功能特性均与热弹性马氏体相变息息相关,其相变特征主要有温度诱发马氏体相变和应力诱发马氏体相变两种机制。研究发现,影响NiTi基合金可逆马氏体转变温度的因素较多,主要有热循环、合金元素、晶粒尺寸和退火温度等。特别是当NiTi记忆合金的晶粒尺寸达到纳米级时,合金对温度与外加应力极为敏感,会表现出与粗晶和超细晶不同的相变特征。晶粒尺寸对纳米晶NiTi形状记忆合金相变的影响主要体现在热诱发马氏体相变及应力诱发马氏体相变两方面。基于此,近年来研究者们对热诱发马氏体相变临界晶粒尺寸、相变温度及应力诱发马氏体相变的临界应力、应力滞后等方面进行了深入研究。对于热诱发马氏体相变,B19′马氏体相变的临界晶粒尺寸约为50 nm,相变温度随晶粒尺寸减小而降低;R相变的临界尺寸约为15 nm,相变温度随晶粒尺寸减小而升高。对于应力诱发马氏体相变,临界相变应力随晶粒尺寸减小而升高。对于应力诱发马氏体相变的应力滞后,研究者们得出了不同的结论,主要是位错与晶粒尺寸对应力滞后共同作用的结果。研究晶粒尺寸对其相变的影响将有利于更好地研究纳米晶NiTi记忆合金,使其在热敏元件、管接头、纳米级致动器及微机电体系等领域有巨大的发展潜力。本文简述了温度诱发马氏体相变和应力诱发马氏体相变机制,主要综述了晶粒尺寸对纳米晶NiTi合金两种诱发马氏体相变机制的影响。

Lithium titanium oxide(Li4Ti5O12,LTO),a‘zero-strain’anode material for lithium-ion batteries,exhibits excellent cycling performance.However,its poor conductivity highly limits its applications.Here,the structural stability and conductivity of LTO were studied using in situ high-pressure measurements and first-principles calculations.LTO underwent a pressure-induced amorphization(PIA)at 26.9 GPa.The impedance spectroscopy revealed that the conductivity of LTO improved significantly after amorphization and that the conductivity of decompressed amorphous LTO increased by an order of magnitude compared with its starting phase.Furthermore,our calculations demonstrated that the different compressibility of the Li O6and Ti O6octahedra in the structure was crucial for the PIA.The amorphous phase promotes Li+diffusion and enhances its ionic conductivity by providing defects for ion migration.Our results not only provide an insight into the pressure depended structural properties of a spinel-like material,but also facilitate exploration of the interplay between PIA and conductivity.

Gibberellin(GA)functions in plant growth and development.However,genes involved in the biosynthesis and regulation of GA in crop plants are poorly understood.We isolated the mutant gad5-1(GAAssociated Dwarf 5),characterized by dwarfing,short internodes,and dark green and short leaves.Map-based gene cloning and allelic verification confirmed that ZmGAD5 encodes ent-kaurenoic acid oxidase(KAO),which catalyzes KA(ent-kaurenoic acid)to GA12 conversion during GA biosynthesis in maize.ZmGAD5 is localized to the endoplasmic reticulum and is present in multiple maize organs.In gad5-1,the expression of ZmGAD5 is severely reduced,and the levels of the direct substrate of KAO,KA,is increased,leading to a reduction in GA content.The abnormal phenotype of gad5-1 was restored by exogenous application of GA3.The biomass,plant height,and levels of GA12 and GA3 in transgenic Arabidopsis overexpressing ZmGAD5 were increased in comparison with the corresponding controls Col-0.These findings deepen our understanding of genes involved in GA biosynthesis,and could lead to the development of maize lines with improved architecture and higher planting-density tolerance.
