| 1 | PECS: Towards Personalized Edge Caching for Future Service-Centric Networks显示文摘Mobile operators face the challenge of how to best design a service-centric network that can effectively process the rapidly increasing number of bandwidth-intensive user requests while providing a higher quality of experience(QoE). Existing content distribution networks(CDN) and mobile content distribution networks(mCDN) have both latency and throughput limitations due to being multiple network hops away from end-users. Here, we first propose a new Personalized Edge Caching System(PECS) architecture that employs big data analytics and mobile edge caching to provide personalized service access at the edge of the mobile network. Based on the proposed system architecture, the edge caching strategy based on user behavior and trajectory is analyzed. Employing our proposed PECS strategies, we use data mining algorithms to analyze the personalized trajectory and service usage patterns. Our findings provide guidance on how key technologies of PECS can be employed for current and future networks. Finally, we highlight the challenges associated with realizing such a system in 5G and beyond. | Ming Yan Wenwen Li Chien Aun Chan Sen Bian Chih-Lin I André F.

| 2 | 土耳其西部新生代斑岩成矿岩浆氧逸度-挥发份元素组成演化特征--来自锆石和磷灰石组成约束显示文摘特提斯成矿域中段的土耳其西部集中产出了与俯冲、碰撞-后碰撞、伸展动力学背景有关的斑岩型铜、钼、金矿床。前人已完成了针对这些斑岩型矿床构造背景的大量研究工作,但对于区内不同构造背景下斑岩型矿床的成矿岩浆源区性质、成矿元素-挥发分含量和成矿物质演化关系尚未有系统研究。而这些研究将对认识中特提斯构造域晚白垩世以来在新特提斯洋俯冲、欧亚板块-Tauride-Anatolide板块碰撞和伸展过程中斑岩矿床形成时地壳厚度、壳幔相互作用方式及成矿物质演化过程具有重要意义。本研究选择土耳其西段三个斑岩成矿带(Tavşanl带、Biga半岛成矿带和Afyon-Konya带)内五个斑岩型矿床的成矿岩体与同期侵入岩-火山岩,开展锆石微量元素和磷灰石主量元素研究,限定碰撞与伸展环境下斑岩型矿床成矿岩浆的形成温度、氧逸度条件及其与岩浆形成时地壳厚度的关系,利用磷灰石F-Cl-S含量组成揭示熔体挥发分和硫元素的物质组成,进而约束新特提斯洋俯冲-碰撞-伸展过程中斑岩系统的深部物质演化规律。研究结果表明,土耳其西部新生代斑岩型矿床成矿岩浆锆石大部分落于高水含量-高氧逸度区间,具有相似的稀土元素标准化配分曲线。从始新世到中新世,锆石氧逸度Ce 4+/Ce 3+比值呈现出先降低(斑岩型Cu-Mo矿到斑岩型Mo矿)后升高(斑岩型Mo-Cu矿到斑岩Au矿)的趋势,且相对于斑岩型Mo矿和Mo-Cu矿,斑岩型Au矿和Cu-Mo矿成矿岩体的锆石形成时具有相对较高的氧逸度。绝大部分斑岩型矿床成矿岩体的锆石Eu N/Eu N*位于0.4~0.7之间,但斑岩型Mo矿和斑岩型Mo-Cu矿床的锆石具有相对较低的Eu N/Eu N*比值,可能是由于在结晶时熔体受斜长石结晶影响较大。锆石微量元素显示(Yb/Gd和Hf/Y-Th/U)锆石组成大部分受岩浆房中角闪石±榍石±磷灰石分离结晶控制。根据锆石Ti温度计估算土耳其西部斑岩型矿床成矿岩体及其相关岩体的形成温度在650~900℃之间,结晶温度从斑岩型Au矿、斑岩型Cu-Mo/Mo-Cu矿至斑岩型Mo矿呈现递减趋势。对于熔体的挥发分与硫含量组成,始新世-渐新世斑岩型Cu-Mo与Mo矿床成矿岩浆相对具有高F和低Cl组成,中新世伸展环境形成的斑岩型Mo-Cu矿和斑岩型Au矿床成矿岩浆Cl含量普遍较高。与成矿岩体同期的暗色包体或基性岩脉中磷灰石计算获得的熔体硫含量均大于侵入体对应熔体的硫含量,且具有不均一的含量组成,表明基性岩浆注入可能为岩浆房提供硫。结合区域动力学和地壳厚度估算,本文认为触发土耳其西部新生代斑岩矿床形成的动力学机制是:在新特提斯洋向北单向汇聚的背景下,北部始新世-渐新世斑岩矿床受控于碰撞后俯冲的新特提斯洋板片(Vardar洋)后撤-回转-断离过程;南部中新世斑岩矿床的形成则受控于爱琴海板片俯冲控制的地壳伸展-减薄过程。北侧Izmir-Ankara-Erzincan缝合带附近的Tavşanl与Biga半岛斑岩成矿带始新世-渐新世斑岩型矿床的形成与熔融-同化-储存-均一过程(MASH)有关,深部地壳热区过程(DCHZ)与中新世Afyon-Konya带斑岩型矿床的形成有关。 | 赵俊兴 苏本勋 UYSAL I brahim AYDIN Faruk 肖燕 SEN Cuneyt 回凯旋 秦克章 | 2021 | 岩石学报2021，37，8： | 2 |
