In the past few years, resource discovery is an important mechanism in P2P applications. P2P networks could be categorized into structured and unstructured. In general, structured P2P networks (DHTs) provide efficient keyword search, but is difficult to offer a variety of search modes. Unstructured P2P networks are applied to highly churn P2P networks, but they are inefficient. In this paper, w...

In this paper, a novel approach for online 3D multi-resolution surface reconstruction of unknown, unstructured environments is presented. The algorithm is based on a probabilistic framework that enables the capture of the uncertainties involved throughout the knowledge gain process. The main contribution of this paper is a stochastic representation for information. We present some results obtai...

Employing a machine learning approach we predict, up to 24 hours prior, a diagnosis of severe sepsis. Strongly predictive models are possible that use only text reports from the Electronic Health Record (EHR), and omit structured numerical data. Unstructured text alone gives slightly better performance than structured data alone, and the combination further improves performance. We also discuss...

Unstructured natural language text contains vast quantities of human knowledge, yet this knowledge is mostly inaccessible to computers. Computers rely on structured representations (e.g. databases) for knowledge organization and retrieval, and cannot easily understand the ambiguity and nuance of human language. Dramatically increasing the accessibility of knowledge through search engines, inter...

This paper investigates analytic robust stability criteria for large-scale cyclic gene–protein regulatory network systems consisting of genes with heterogeneous dynamics combined with parametric or unstructured uncertainties from a control-theoretic viewpoint. We first consider a class of gene expressions, which is described as an uncertain linear transcription–translation model (LTTM) with fee...

The ability of Escherichia coli RNase H1 to hydrolyze structured substrates containing antisense oligonucleotides preannealed to a 47-mer RNA was compared with its ability to hydrolyze unstructured substrates containing antisense oligonucleotides duplexed with 13-mer RNA. These results demonstrate that when antisense oligonucleotides were bound to structured RNA, the resultant duplexes were cle...
