introduction: this paper used generalized gamma (gg) distribution to find the predictive factors of overall survival (os) after haematopoietic stem cell transplant (hsct) in acute myeloid  leukemia patients. methods: discrimination among the exponential, weibull, gg, log-logistic, and lognormal distributions was done using maximum likelihood and akaike information criteria. results: the 5-year ...

Due to advances in computer technology, many organizations have a large number of workstation-class machines connected by LAN. Such a network of workstations (NOW) can be used for parallel processing, including database query processing. This paper proposes a new load sharing algorithm for hash join processing on NOWs. This new algorithm combines a chunking method with hash join to manage dynam...

This paper presents the Augmented Ambient project that aims to construct a highly interactive mobility scenario based on augmented reality applications running on heterogeneous multimedia devices. Mobility is made available through ambient networks, which are dynamic computer networks. A case study has been performed about a virtual museum, where users join a service network that includes art p...

Multi-way joins improve performance by avoiding extra I/Os from multiple partitioning steps. There are several multi-way join algorithms proposed, and the research results are encouraging. However, commercial database systems are not currently using multi-way joins. Practical issues include modifying the optimizer and execution system to support multi-way operators and ensuring robust and relia...

introduction: the traditional goal of the treatment of acute myelogenous leukemia is to produce and maintain a complete remission (cr).the difference in survival time was entirely attributable to the duration of time spent in cr .in this study, the outcome of aml patients with allogeneic hsct in cr1 versus other than cr1 was compared. patients and methods: since march 1991 until november 2008, ...

Das Projekt IKAR/OS (Intelligent Knowledge and Research Operating System) hat sich zum Ziel gesetzt, ein intelligentes Wissensmanagementsystem für die Lebenswissenschaften zu entwickeln. Das Projekt wird von der Firma iAS GmbH (CEO Dr. Hirsch) in Zusammenarbeit mit dem Humanwissenschaftlichen Zentrum der LMU München (Prof. Pöppel) und der Universität Bremen (Prof. Schill) durchgeführt.

In a typical commercial multi-core processor, the last level cache (LLC) is shared by two or more cores. Existing studies have shown that the shared LLC is beneficial to concurrent query processes with commonly shared data sets. However, the shared LLC can also be a performance bottleneck to concurrent queries, each of which has private data structures, such as a hash table for the widely used ...
