| 1 | A Lookahead Read Cache: Improving Read Performance for Deduplication Backup Storage显示文摘数据 deduplication (dedupe 为短) 是一种特殊数据压缩技术。节省备份时间以及存储空间广泛地被采用了,特别地在备份存储系统。因此,大多数 dedupe 研究首先集中了于改进 dedupe 写性能。然而,备份存储 dedupe 读了性能也是为存储恢复的一个关键问题。新 dedupe 存储读了的图案为改善的备份应用程序缓冲的这篇论文由利用一个特殊特征读了性能:读的顺序与 write 顺序一样。为更好的缓存利用,由在一个动人的窗口以内向前寻找未来引用,因而,它从有最小的未来存取的缓存驱逐牺牲品。而且,进一步改进读的缓存性能,贤明地缓冲未来存取数据块维持一个小日志缓冲区。有真实世界的备份工作量的广泛的实验证明建议读的缓存计划在多达 64.3% | Dongchul Park Ziqi Fan Young Jin Nam David H.

| 3 | Extending SSD Lifespan with Comprehensive Non-Volatile Memory-Based Write Buffers显示文摘New non-volatile memory (NVM)technologies are expected to replace main memory DRAM (dynamic random access memory)in the near future.NAND flash technological breakthroughs have enabled wide adoption of solid state drives (SSDs)in storage systems.However,flash-based SSDs,by nature,cannot avoid low endurance problems because each cell only allows a limited number of erasures.This can give rise to critical SSD reliability issues.Since many SSD write operations eventually cause many SSD erase operations,reducing SSD write traffic plays a crucial role in SSD reliability. This paper proposes two NVM-based buffer cache policies which can work together in different layers to maximally reduce SSD write traffic:a main memory buffer cache design named Hierarchical Adaptive Replacement Cache (H-ARC)and an internal SSD write buffer design named Write Traffic Reduction Buffer (WRB).H-ARC considers four factors (dirty,clean, recency,and frequency)to reduce write traffic and improve cache hit ratios in the host.WRB reduces block erasures and write traffic further inside an SSD by effectively exploiting temporal and spatial localities.These two comprehensive schemes significantly reduce total SSD write traffic at each different layer (i.e.,host and SSD)by up to 3x.Consequently,they help extend SSD lifespan without system performance degradation. | Ziqi Fan Dongchul Park | 2019 | Journal of Computer Science & Technology2019，34，1： | 1 |

| 6 | Electrodeposited copper oxides with a suppressed interfacial amorphous phase using mixed-crystalline ITO and their enhanced photoelectrochemical performances显示文摘The effectiveness of photoelectrochemical(PEC)water splitting is significantly restricted by insufficient light harvesting,rapid charge recombination,and slow water reduction kinetics.Since the presence of amorphous phases in the interfaces hinders the overcome of these inherent limitations,a photoelectrode must be built strategically.Herein,we artificially controlled the crystallographic orientation of indium tin oxide(ITO)to determine the orientation with the smallest lattice mismatch at the Cu_(2)O interface,thus significantly reducing the amorphous phase in the early stage of electrodeposition nucleation.The[222]/[400]mixed orientation ITO primarily exposed the{400}surface planes and accelerated charge transfer by forming an optimal interface with preferentially grown(111)oriented Cu_(2)O and minimized amorphous region.In addition,the ITO surface energy was calculated using density functional theory to theoretically verify which plane is more active for growing the photoactivation layer.The rationally designed ITO/Cu_(2)O/Al-dope Zn O/TiO_(2)/Rh-P device,with each layer serving a specific purpose,achieved a photocurrent density of 8.23 mA cm^(-2)at 0 VRHEunder AM 1.5 G illumination,providing a standard method for effective solar-to-hydrogen conversion photocathodes. | Ji Hoon Choi Hae-Jun Seok Dongchul Sung Dong Su Kim Hak Hyeon Lee Suklyun Hong Han-Ki Kim Hyung Koun Cho | 2023 | Journal of Energy Chemistry2023，，7： | 1 |

| 12 | Hot Data Identification with Multiple Bloom Filters: Block-Level Decision vs I/O Request-Level Decision显示文摘尽管很少调查检查了这个对象,热数据鉴定为许多应用是关键的。所有存在研究几乎专门集中于频率。然而,有效地识别热数据就崭新和频率而言同等地要求。而且,以前的研究在数据块水平做热数据决定。因为它的随机的存取完成与它的顺序的存取可比较的性能,如此的一个有细密纹理的决定为基于闪光的存储特别地适合很好。然而,硬盘驱动器(HDD ) 有在顺序、随机的存取之间的重要性能不同。不同于基于闪光的存储,因此利用不对称的 HDD 存取性能要求做一个纹理粗糙的决定。这份报纸建议采用多重花蕾过滤器高效地描绘崭新以及频率的一个新奇热数据鉴定计划。因而,它不仅消费 50% 更少的存储器和多达 58% 不太计算的开销,而且与一个最先进的计划相比降低假鉴定率直到 65% 。而且,我们把计划用于一种下一代 HDD 技术,即, Shingled 磁性的记录(SMR ) ,验证它的有效性。为这,我们设计新热数据鉴定有一个纹理粗糙的决定的基于的 SMR 开车。实验表明精确热数据鉴定的重要性和好处,从而在多达 42% 改进建议 SMR 驱动器性能。 | Dongchul Park Weiping He H.

| 13 | The westward intrusion of south Pacific water at the western tip of the New Guinea Island显示文摘From the eastern Indonesian cruise from November 14 to 23, 2007, CTD (conductivity, temperature, depth profiler) /ADCP (acoustic Doppler current profiler)casting and seawater sampling were done at 25 stations around Waigeo Island near New Guinea Island. It was found overall westward intrusion of the south Pacific waters into the Seram Sea and southward spreading of the north and south Pacific waters into the Seram Sea. There is westward residual flow along the channel between Waigeo and New Guinea within upper 200 m with the maximum speed up to 50 cm/s, and much weaker eastward flow in the lower layer (< 10 cm/s) due to blocking by the shallow sill at the west of the Dampier Strait. The abrupt change of bottom topography induces active horizontal and vertical mixing which results in a three-layered current system with a major through-flow of -0.99 Sv (Sv = 10 6 m 3 /s) into the Seram Sea; the transports in the upper and the lower layers are -1.14 Sv and -0.24 Sv (westward), respectively, and in the middle there is a return flow with the transport of +0.39 Sv (eastward). | KIM Eung JEON Dongchull Hadikusumah | 2013 | Acta Oceanologica Sinica2013，32，1： | 0 |
