TL;DR: In this paper, the authors measured the transverse spin azimuthal asymmetry of charged hadrons produced in semi-inclusive deep inelastic scattering using a 160 GeV mu(+) beam and a transversely polarised NH3 target.

TL;DR: This paper provides a survey of recent results addressing the clique-width of graphs in a certain class of graphs and shows that for many classes of graphs, this parameter has been proved to be unbounded.

TL;DR: Biochemical investigations revealed that the Bg/II fragment codes for a Pt N-acetyltransferase, a potent inhibitor of glutamine synthetase, and subcloning this fragment downstream from the lacZ promoter conferred Ptt resistance to Escherichia coli JM83 in one of the two possible orientations.

TL;DR: The analysis reveals that visual homing can succeed even in the presence of many incorrect feature correspondences, and that low-frequency features are sufficient for homing.
Abstract: Insects are able to return to important places in their environment by storing an image of the surroundings while at the goal, and later computing a home direction from a matching between this 'snapshot' image and the currently perceived image. Very similar ideas are pursued for the visual navigation of mobile robots. A wide range of different solutions for the matching between the two images have been suggested. This paper explores the application of optical flow techniques for visual homing. The performance of five different flow techniques and a reference method is analysed based on image collections from three different indoor environments. We show that block matching, two simple variants of block matching and two even simpler differential techniques produce robust homing behaviour, despite the simplicity of the matched features. Our analysis reveals that visual homing can succeed even in the presence of many incorrect feature correspondences, and that low-frequency features are sufficient for homing. In particular, the successful application of differential methods opens new vistas on the visual homing problem, both as plausible and parsimonious models of visual insect navigation, and as a starting point for novel robot navigation methods.
