01 Jun 2014TL;DR: An incremental joint framework to simultaneously extract entity mentions and relations using structured perceptron with efficient beam-search is presented, which significantly outperforms a strong pipelined baseline, which attains better performance than the best-reported end-to-end system.
Abstract: We present an incremental joint framework to simultaneously extract entity mentions and relations using structured perceptron with efficient beam-search. A segment-based decoder based on the idea of semi-Markov chain is adopted to the new framework as opposed to traditional token-based tagging. In addition, by virtue of the inexact search, we developed a number of new and effective global features as soft constraints to capture the interdependency among entity mentions and relations. Experiments on Automatic Content Extraction (ACE) 1 corpora demonstrate that our joint model significantly outperforms a strong pipelined baseline, which attains better performance than the best-reported end-to-end system.

TL;DR: A modular engineering approach was systematically removed metabolic pathway bottlenecks and led to significant titre improvements in a multi-gene fatty acid metabolic pathway to demonstrate a generalized approach to engineering cell factories for valuable metabolites production.
Abstract: Microbial fatty acid-derived fuels have emerged as promising alternatives to petroleum-based transportation fuels. Here we report a modular engineering approach that systematically removed metabolic pathway bottlenecks and led to significant titre improvements in a multi-gene fatty acid metabolic pathway. On the basis of central pathway architecture, E. coli fatty acid biosynthesis was re-cast into three modules: the upstream acetyl coenzyme A formation module; the intermediary acetyl-CoA activation module; and the downstream fatty acid synthase module. Combinatorial optimization of transcriptional levels of these three modules led to the identification of conditions that balance the supply of acetyl-CoA and consumption of malonyl-CoA/ACP. Refining protein translation efficiency by customizing ribosome binding sites for both the upstream acetyl coenzyme A formation and fatty acid synthase modules enabled further production improvement. Fed-batch cultivation of the engineered strain resulted in a final fatty acid production of 8.6 g l(-1). The modular engineering strategies demonstrate a generalized approach to engineering cell factories for valuable metabolites production.

TL;DR: The conformational ensembles of the Abeta40 and Abeta42 peptide monomers are characterized by using a combination of molecular dynamics and measured scalar data from NMR experiments to confirm the existence of structured regions within the otherwise flexible Abeta peptides.

TL;DR: The results suggest that an MEG-based BCI that uses voluntary amplitude modulation of sensorimotor mu and beta rhythms is feasible and efficient in terms of user training and a simple spatial filtering method that takes the geometric properties of signal propagation in MEG into account is presented.

TL;DR: This article examined the relationship between improvisation and entrepreneurial intentions and found that improvisation accounts for a significant amount of variance in entrepreneurial intention above and beyond what is accounted for by other relevant individual difference measures.
Abstract: This study examines the relationship between improvisation and entrepreneurial intentions. Of specific interest is whether or not a proclivity for improvisation explains any variance in entrepreneurial intentions beyond what is accounted for by other relevant individual difference measures. Using a sample of 430 college students, entrepreneurial intentions are found to be significantly associated with measures of personality, motivation, cognitive style, social models, and improvisation. The strongest relationship is found between entrepreneurial intentions and improvisation. The results of hierarchical regression show that improvisation accounts for a significant amount of variance in entrepreneurial intention above and beyond what is accounted for by the other variables.
