Key-value （KV） stores have become a backbone of large-scale applications in today＇s data centers. Write- optimized data structures like the Log-Structured Merge-tree （LSM-tree） and their variants are widely used in KV storage systems like BigTable and RocksDB. Conventional LSM-tree organizes KV items into multiple, successively larger components, and uses compaction to push KV items from one smaller component to another adjacent larger component until the KV items reach the largest component. Unfortunately, current compaction scheme incurs significant write amplification due to repeated KV item reads and writes, and then results in poor throughput. We propose a new compaction scheme, delayed compaction （dCompaction） that decreases write amplification, dCompaction postpones some compactions and gathers them into the following compaction. In this way, it avoids KV item reads and writes during compaction, and consequently improves the throughput of LSM-tree based KV stores. We implement dCompaction on RocksDB, and conduct extensive experiments. Validation using YCSB framework shows that compared with RocksDB, dCompaction has about 40% write performance improvements and also comparable read performance.

Cognitive radio has been recently proposed as a promising technology to improve the spectrum utilization. In this paper, we consider a system where a licensed radio spectrum is shared by a primary network and a secondary network. Based on the subspace theory, a novel low-complexity algorithm for secondary user selection has been proposed. On the basis of the scheduling scheme, we jointly consider transmit beamforming, scheduling and power allocation, and subsequently present a complete set of solution for secondary network downlink. Simulation results has shown that our proposed scheme not only can limit the introduced interference at primary users within the tolerable range, but also can achieve high sum-rate throughput of secondary network, simultaneously. Furthermore, as is proved by simulation results, our scheme is very robust due to the fact that only a little tolerable performance drop is introduced when simple but nonoptimal equal power allocation is adopted.

AIM:To establish a new inflammatory animal model of meibomian gland dysfunction(MGD)in C57BL/6 ***:C57BL/6 mice were randomly divided into complete Freund’s adjuvant(CFA)group(14 animals,14 eyes),naphthazolin hydrochloride(NH)group(14 animals,14 eyes)and control group(14 animals,14 eyes).In CFA group,CFA was used in eyelid conjunctiva injection;in NH group,NH eye drops were used twice a day;control group was injected with equal dose of saline at the same time point and same site with animals in CFA *** meibomian gland orifices score(MGOS)was evaluated on a scale of 0 to 3 in the middle five meibomian gland orifices of the upper and lower eyelid using slit *** the successful induction of each animal model,intense pulsed light(IPL)was introduced on each mouse in CFA and NH *** red O(ORO),hematoxylin and eosin(H&E)staining were performed before and after successful induction of CFA,NH and control ***:At 12wk after CFA injection,inflammatory cell infiltration and fiber necrosis was observed,with acinar density and duct dilatation significantly lower compared with control *** NH group,the meibomian gland acini were relatively smaller and deformed compared with control group,the number of meibomian gland acini was also slightly *** inflammatory cell or fiber necrosis was observed in NH *** three times of IPL treatment(5/10 mice in each group,and the other 5 mice served as non-IPL control),MGOS was significantly lower in IPL-treated mice in NH group(P<0.01).After three times of IPL treatment,the MGOS of NH group was significantly lower than that in the CFA group(P<0.01).CONCLUSION:We develop a novel animal model that studies the role of inflammation in the development of MGD and IPL *** model indicates that persistent inflammatory state may be the cause of MGD and weaken the therapeutic effect of IPL.
