Multiple oil drops bouncing on the surface of a vertically vibrating bath of the same oil exhibit self-organization behavior in two dimensions [S. Protière, Y. Couder, E. Fort, and A. Boudaoud, J. Phys.: Condens. Matter 17, S3529 (2005)]. We describe further the morphology and dynamic behavior of stable assemblies of large bouncing oil drops, for which we find that both the spacing and the latt...

Knowledge work is beset with uncertainty. Part of the challenge of designing systems to support knowledge work is to do so in a way which is sympathetic to this. We report a study of information gathering in the context of a news research and writing tasks. The evaluation was performed with a test-bed integrated system called NewsHarvester which supports search, document display, text gathering...

Floating Car Data (FCD) has been analyzed for various purposes in past years. However, limited research about the behaviors of taking long-distance taxi rides has been made available. In this paper, we used data from over 12,000 taxis during a six-month period in Shanghai to analyze the spatiotemporal patterns of long-distance taxi trips. We investigated these spatiotemporal patterns by compari...

One of the remarkable properties of Verb Second (V2) syntax is the fact that the constituent preceding the finite verb – let’s for simplicity call it ‘SpecCP’ – can under certain circumstances be dropped (cf. Ross 1982; Huang 1984; Fries 1988 for German, Ackema & Neeleman 2007 for Dutch). Pronoun drop is strictly confined to pronouns in SpecCP and can only occur in the root clause. In a context...

In September 2001, during follow-up at our outpatient liver unit we detected by ultrasound a hypervascular mass adjacent to the VI hepatic segment in a 78-year-old HCV-positive cirrhotic woman. Subsequently abdominal computed tomography (CT) revealed an infiltrative vascularized nodule (3.5 cm in diameter) at the lower border of the VI hepatic segment and magnetic resonance imaging showed a “te...

In this work, a mechanistic model of drop coalescence based upon a stochastic film-drainage analysis is developed. The coalescence model accounts for previously considered factors, such as turbulence intensity, drop size, and drop deformability, while additionally describing the dual effects of drop surface potential and system electrolyte concentration. Model results indicate that electrostati...

This is the Cayley surface when N = 3. The next few are as follows. x4 = x1x3 + 1 2 x2 2 − x1 x2 + 1 4 x1 4 x5 = x1x4 + x2x3 − x1 x3 − x1x2 2 + x1 x2 − 1 5 x1 5 x6 = x1x5 + x2x4 + 1 2 x3 2 − x1 x4 − 2x1x2x3 − 1 3 x2 3 + x1 x3 + 3 2 x1 x2 2 − x1 x2 + 1 6 x1 . Since the first term in (1) is −xN and this is the only occurrence of this variable, these hypersurfaces are polynomial graphs over the re...
