Stable-isotope-labeled precursors were used to establish the biosynthetic pathway leading from β-alanine towards isoxazolin-5-one glucoside 1 and its 3-nitropropanoate (3-NPA) ester 2 in Chrysomelina larvae. Both structural elements originate from sequestered plant-derived β-alanine or from propanoyl-CoA that is derived from the degradation of some essential amino acids, e.g. valine. β-Alanine ...

The new anamorphic yeast Kuraishia piskuri, f.a., sp. nov. is described for three strains that were isolated from insect frass from trees growing in Florida, USA (type strain, NRRL YB-2544, CBS 13714). Species placement was based on phylogenetic analysis of nuclear gene sequences for the D1/D2 domains of large subunit rRNA, small subunit rRNA, translation elongation factor-1α, and subunits B1 a...

In this paper we describe a model for automatically generating video documentaries. This allows viewers to specify the subject and the point of view of the documentary to be generated. The domain is matter-of-opinion documentaries based on interviews. The model combines rhetorical presentation patterns used by documentary makers with a data-driven approach. Rhetorical presentation patterns prov...

In this demonstration, we propose an approach for enriching the user experience when watching television using a second screen device. The user can control the video program being watched using a Kinect and can grab, at any time, a fragment from this video. Then, we perform named entity recognition on the subtitles of this video fragment in order to spot relevant concepts. Entities are used to ...

With the emergence of search engines and crowdsourcing websites, machine learning practitioners are faced with datasets that are labeled by a large heterogeneous set of teachers. These datasets test the limits of our existing learning theory, which largely assumes that data is sampled i.i.d. from a fixed distribution. In many cases, the number of teachers actually scales with the number of exam...
