Part I: Effect of Nanomicelle Size on Trans-scleral Permeability of Dexamethasone and Part II: Strategies to Minimize Octreotide Acylation during Sustained Release from Biodegradable Polymers
… mPEG₇₅₀-PCL₇₀₀ (DB1), mPEG₂₀₀₀-PCL₁₅₀₀ (DB2) and mPEG₅₀₀₀-PCL₄₀₀₀ (DB3) were synthesized by ring opening polymerization. Polymers were characterized by H¹ NMR (structure), gel permeation chromatography (molecular weights and polydispersity), critical micelle concentration (CMC) and in …

Tuning Big Data Systems Via Deep Learning
Modern database systems, including IBM Db2 have numerous parameters, “knobs,” that require precise configuration to achieve optimal workload performance. Even for experts, manually “tuning” these knobs is a challenging process. We present Db2une, an automatic query-aware tuning system that …

Autonomic Workload Management for Database Management Systems
… a prototype system implemented on top of IBM DB2 Workload Manager. Our prototype system leverages the existing workload management facilities and implements a set of corresponding controllers to adapt to dynamic and mixed workloads while protecting DBMSs against severe performance degradation.

Fundamentals and applications of order dependencies
… over our prototype implementation in IBM® DB2® using the TPC-DS® benchmark schema and some customer inspired queries. Our experimental results demonstrate a significant performance gain. Dependencies have played an important role in database theory. We study the theoretical aspects of order …

Optimization of deep boreholes for disposal of high-level nuclear waste
… permeability than the surrounding rock, while DB2 assumes a 0.1 mm diameter fracture. For the limiting design basis (DB 1), borehole repository design is constrained (via dose limits) by the areal loading of SNF (MTHM/km2 ), which increases linearly with disposal depth. In the final portion of …

STABLE ISOTOPIC INSIGHTS INTO THE SUBSISTENCE PATTERNS OF PREHISTORIC DOGS (CANIS FAMILIARIS) AND THEIR HUMAN COUNTERPARTS IN NORTHEASTERN NORTH AMERICA
… from carbonate three dogs, two from New Jersey (DB2, DB8) and one from Maryland (DB11), had a significant C4 plant component to their diet. The remaining Late Woodland and Historic period dogs most likely consumed minor amounts of C4 resources. In addition to identifying C4 resources in the diet …

Developing, Optimizing and Hosting Data-Driven Web Applications
… of commercial database systems such as Oracle, DB2 and SQL Server are usually very expensive and difficult to manage. At the other extreme, low-cost data hosting solutions such as Amazon's SimpleDB do not support sophisticated data manipulation primitives such as joins that are necessary for …
