Sow culling rates have a direct correlation to the economic efficiency of both breeding herd and commercial herd. Analyzing the reasons of sow culling could lead to improve production efficiency of farms. This study, which involved inspections of four farms in Southern China, manifested that the rate of unplanned sow-culling has reached to 78.1% in total(More)
The IGF system plays important roles in growth. Nevertheless, few data have been reported so far on the expression of IGF system members and their relationship with growth in domestic animals, especially pigs. In this study, hepatic transcript level of IGF1, IGF2, IGF binding protein 2 (IGFBP2), IGFBP3 and IGF 1 receptor (IGF1R), plasma protein level of(More)
BACKGROUND Surgical excision (SE) is a first-line treatment for basal cell carcinoma (BCC). Topical photodynamic therapy (PDT) has also been used and has cosmetic advantages over surgery. The latest European guidelines for topical PDT recommended that it be used to treat nodular basal cell carcinoma (nBCC) but a consensus has not been reached. Our study was(More)
Real-life behaviors shown by the mobile users typically exhibit plenty noises, making it hard to construct an effective recommendation engine. In this paper, we present a fused model based on the LR algorithm and the GBDT algorithm to recommend vertical industry commodities in a mobile setting. A set of specifically designed methods are proposed to deal(More)
This paper proposes the GraphF abstraction which exploits Adaptive Radix Tree for efficient graph indexing with lower storage cost. Leveraging the GraphF abstraction, we implement a separate graph computation engine on Spark. Experiments showed that on average GraphF outperforms GraphX and PowerGraph by up to 8.1X and 3.6X separately in execution time both(More)
HyperLogLog Counting is widely used in cardinality estimation. It is the foundation of many algorithms in data analysis, commodity recommendation and database optimization. Facing the large scale internet business like electronic commerce, internet companies have an urgent requirement of distributed real-time cardinality estimation with high accuracy and(More)
Fingerprint has been widely used in a variety of biometric identification systems in the past several years due to its uniqueness and immutability. With the rapid development of fingerprint identification techniques, many fingerprint identification systems are in urgent need to deal with large-scale fingerprint storage and high concurrent recognition(More)
The tasks of data-parallel computation jobs come up with diverse and time-varying resource requirements. The dynamic nature of task requirements brings challenges on making good scheduling decisions, due to it is hard to keep work-conserving. In this paper, we present BETS to cope with the requirement dynamics that aims at utilizing cluster resources fully.(More)
This paper studies the communication pattern of data-parallel applications from the perspective of job execution, and discovers multiple inter-coflow dependencies. These inter-coflow dependencies, collectively named as semantic flow (seflow), can expose job-level semantics. It is observed that most distributed computing frameworks describe their job(More)
