In this paper we propose a data mining technique for the efficient prediction of rare events, such as heat waves, network intrusions and engine failures, using inter transactional patterns. Data mining is a research area that attempts to assist the decision makers with a set of tools to treat a wide range of real world problems that the traditional statistical and mathematical approaches are no...

Smart contracts running on public blockchains are permissionless and decentralized, attracting both developers malicious participants. Ethereum, the world’s largest decentralized application platform which more than 40 million smart running, is frequently challenged by contract vulnerabilities. What’s worse, since homogeneity of a wide range increase in inter-contract dependencies, vulnerabilit...

Current transaction systems for geo-distributed datastores either have high transaction processing latencies or are unable to support general transactions with dependent operations. In this paper, we introduce CrossStitch, an efficient transaction processing framework that reduces latency by restructuring each transaction into a chain of state transitions, where each state consists of a key ope...

In the current electronic-commerce literature, a commercial transaction is commonly viewed as an exchange between two autonomous principals operating under a contract between them— which needs to be formalized and enforced. But the situation can be considerably more complex in the case of inter-enterprise (also called business-to-business, or B2B) commerce. The participants in a B2B transaction...

A business to business (B2B) e-marketplace is an Internet-based inter-organizational system that facilitates online businesses. It provides two basic functions: search and transaction. Accordingly, organizational usage of B2B e-marketplaces varies across these two functions. The previous research mainly applies the Diffusion of Innovation (DOI) theory to predict the usage of B2B e-marketplaces,...

The paper presents our work on the annotation of intra-chunk dependencies on an English treebank that was previously annotated with Inter-chunk dependencies, and for which there exists a fully expanded parallel Hindi dependency treebank. This provides fully parsed dependency trees for the English treebank. We also report an analysis of the inter-annotator agreement for this chunk expansion task...

Transactional Memory (TM) provides a strong abstraction to tackle the challenge of synchronizing concurrent tasks that access shared state. Yet, most TMs do not allow a single transaction to contain parallel code. We propose an efficient parallel nesting algorithm to explore existing latent parallelism within a transaction. If this intra-transaction parallelism has reduced conflict probability ...

In current mainframe architectures, extended memory is used as a pageaddressable main memory extension to improve I/O performance. If made non-volatile, extended memory can significantly increase transaction processing performance. In this paper, we study how locally distributed transaction systems may use shared extended memory to support high transaction rates and short response times. We out...
