Detecting abnormal fish trajectories using clustered and labeled data

Cigdem Beyan, Robert B. Fisher
2013 2013 IEEE International Conference on Image Processing  
First we extract a set of features from trajectories and apply PCA. We then perform clustering on a subset of features. Based on the clustering, outlier detection is applied to each cluster.  ...  The paper presents two innovations: 1) a novel approach to abnormal trajectory detection and 2) improved performance on video based abnormal trajectory analysis of fish in unconstrained conditions.  ...  ACKNOWLEDGEMENTS This research was funded by European Commission FP7 grant 257024, in the Fish4Knowledge project (www.fish4knowledge.eu).  ...

Towards Data-Driven Hierarchical Surgical Skill Analysis [article]

Bin Li, Berenice Mettler, Timonthy M. Kowalewski
2015 arXiv   pre-print
This paper evaluates methods of hierarchical skill analysis developed in aerospace to the problem of surgical skill assessment and modeling.  ...  Outcomes are evaluated based on their ability to provide relevant information about the underlying processes across the entire system hierarchy including control, guidance and planning.  ...  In the dynamic clustering method, the dynamics of human-agent-environment interaction is described with Piece-Wise Auto-Regressive eXogenous (PWARX) model given in a parametric state-space form.  ...

Mechanism of activation of the human cysteine desulfurase complex by frataxin

Shachin Patra, David P. Barondeau
2019 Proceedings of the National Academy of Sciences of the United States of America  
FXN specifically accelerates each of these individual steps in the mechanism.  ...  Here, we develop a radiolabeling assay and use stopped-flow kinetics to establish that FXN is functionally linked to the mobile S-transfer loop cysteine of NFS1.  ...  This work was supported, in part, by NIH Grant R01GM096100, National Science Foundation Grant CHE 1508269, and Welch Foundation Grant A-1647.  ...

Molecular Dynamics Simulations and Classical Multidimensional Scaling Unveil New Metastable States in the Conformational Landscape of CDK2

Pasquale Pisani, Fabiana Caporuscio, Luca Carlino, Giulio Rastelli, Claudio M Soares
2016 PLoS ONE  
The method here presented should not be limited to the CDK2 case but could be used to systematically unmask similar mechanisms throughout the human kinome.  ...  The Activation Loop (A-loop), which is positioned between the DFG and a third conserved motif, APE, is one of the most variable regions of PKs and is involved in substrate binding.  ...  The K-means clustering method was discarded because it was not able to partition the DFG-out conformation as a separate cluster.  ...

Researching for sustained translation from site cluster permeability into building courtyard and interior atrium

FX Teddy Badai Samodra, Ima Defiana, Wahyu Setyawan
2018 IOP Conference Series: Earth and Environment  
Thus, it has potency for energy efficiency when grid, loop, and cul-de-sac site clusters, with 25% of ground coverage, have connectivity with building courtyard compared to the atrium.  ...  In general, it was more energy efficient option as part of a low rise building, while the courtyard building performed better with increasing irregular building height more than 90% of the difference.  ...  Therefore, a significant increase in energy efficiency when the grid, the loop, and the cul-de-sac site clusters, with 25% of ground coverage, have connectivity with building courtyard compared to the  ...

Origin and Evolution of Viral Interleukin-10 and Other DNA Virus Genes with Vertebrate Homologues

Austin L. Hughes
2002 Journal of Molecular Evolution  
Though the mutation rate in these viral genes is up to 20 times that of the corresponding mammalian genes, a high mutation rate alone did not account for these differences because they were not seen in  ...  Furthermore, a nonrandom pattern of change with respect to amino acid residue charge in the N-terminal portion of the mature protein has occurred repeatedly in independently derived viral IL-10 genes,  ...  This research was supported by Grant GM00614 from the National Institutes of Health and by a grant from the South Carolina Commission on Higher Education.
