| retention prediction of low molecular weight anions in ion chromatography based on quantitative structure-retention relationships applied to the linear solvent strength model. | quantitative structure-retention relationships (qsrrs) represent a popular technique to predict the retention times of analytes, based on molecular descriptors encoding the chemical structures of the analytes. the linear solvent strength (lss) model relating the retention factor, k to the eluent concentration (log k=a-blog [eluent]), is a well-known and accurate retention model in ion chromatography (ic). in this work, qsrrs for inorganic and small organic anions were used to predict the regress ... | 2017 | 28057331 |
| marine reserve targets to sustain and rebuild unregulated fisheries. | overfishing threatens the sustainability of coastal marine biodiversity, especially in tropical developing countries. to counter this problem, about 200 governments worldwide have committed to protecting 10%-20% of national coastal marine areas. however, associated impacts on fisheries productivity are unclear and could weaken the food security of hundreds of millions of people who depend on diverse and largely unregulated fishing activities. here, we present a systematic theoretic analysis of t ... | 2017 | 28056064 |
| learning discriminative bayesian networks from high-dimensional continuous neuroimaging data. | due to its causal semantics, bayesian networks (bn) have been widely employed to discover the underlying data relationship in exploratory studies, such as brain research. despite its success in modeling the probability distribution of variables, bn is naturally a generative model, which is not necessarily discriminative. this may cause the ignorance of subtle but critical network changes that are of investigation values across populations. in this paper, we propose to improve the discriminative ... | 2015 | 28055846 |
