It is widely realized that the integration of database and information retrieval techniques will provide users with a wide range of high quality services. In this paper, we study processing an l-keyword query, p<sub>1</sub>, p<sub>1</sub>, ..., p<sub>l</sub>, against a relational database which can be modeled as a weighted graph, G(V, E). Here V is a set of(More)
BACKGROUND High-throughput profiling of DNA methylation status of CpG islands is crucial to understand the epigenetic regulation of genes. The microarray-based Infinium methylation assay by Illumina is one platform for low-cost high-throughput methylation profiling. Both Beta-value and M-value statistics have been used as metrics to measure methylation(More)
Geographically-grounded situational awareness (SA) is critical to crisis management and is essential in many other decision making domains that range from infectious disease monitoring, through regional planning, to political campaigning. Social media are becoming an important information input to support situational assessment (to produce awareness) in all(More)
Performance isolation is a key challenge in cloud computing. Unfortunately, Linux has few defenses against performance interference in shared resources such as processor caches and memory buses, so applications in a cloud can experience unpredictable performance caused by other programs' behavior. Our solution, CPI<sup>2</sup>, uses cycles-per-instruction(More)
Marginal agricultural land is estimated for biofuel production in Africa, China, Europe, India, South America, and the continental United States, which have major agricultural production capacities. These countries/regions can have 320-702 million hectares of land available if only abandoned and degraded cropland and mixed crop and vegetation land, which(More)
Pulps with residual lignin ranging from 6.4-27.4% (w/w) were prepared from mixed softwoods using a proprietary biorefining technology (the Lignol process) based on aqueous ethanol organosolv extraction. The pulps were evaluated for bioconversion using enzymatic hydrolysis of the cellulose fraction to glucose and subsequent fermentation to ethanol. All pulps(More)
Modern multi-core processors present new resource management challenges due to the subtle interactions of simultaneously executing processes sharing on-chip resources (particularly the L2 cache). Recent research demonstrates that the operating system may use the page coloring mechanism to control cache partitioning, and consequently to achieve fair and(More)
BACKGROUND Surplus oocytes in assisted reproduction treatment cycles could be saved and donated to other couples. ICSI is usually performed for oocytes that have been stored frozen, considering possible exocytosis of cortical granules (CG). The unavoidability of ICSI merits further study. METHODS We used a slow method to freeze excess oocytes from(More)
— With today's ASIC technology, a large number of memory can be easily implemented in a single chip. This makes the combined input-crosspoint-queued (CICQ) crossbar switch a more attractive solution than the traditional input-queued (IQ) crossbar switch because of the simplicity of the CICQ switch scheduling. In this paper, we propose a shortest crosspoint(More)
CONTEXT A triple-marker approach for chronic kidney disease (CKD) evaluation has not been well studied. OBJECTIVE To evaluate whether combining creatinine, cystatin C, and urine albumin-to-creatinine ratio (ACR) would improve identification of risks associated with CKD compared with creatinine alone. DESIGN, SETTING, AND PARTICIPANTS Prospective cohort(More)
