Museums offer vast amounts of information, but a visitor’s receptivity and time are typically limited, providing the visitor with the challenge of selecting the (subjectively) interesting exhibits to view within the available time. Mobile, electronic handheld guides offer the opportunity to improve a visitor’s experience by recommending exhibits of interest, and adapting the delivered content. ...

Contrary to classical population genetics theory, experiments demonstrate that fluctuating selection can protect a haploid polymorphism in the absence of frequency dependent effects on fitness. Using forward simulations with the Moran model, we confirm our analytical results showing that a fluctuating selection regime, with a mean selection coefficient of zero, promotes polymorphism. We find th...

We present two geometric proofs for KochenSpecker’s theorem [S. Kochen, E. P. Specker: The problem of hidden variables in quantum mechanics, J. Math. Mech. 17 (1967), 5987]. A quite similar argument has been used by Cooke, Keane, Moran [R. Cooke, M. Keane, W. Moran: An elementary proof of Gleason’s theorem, Math. Proc. Camb. Phil. Soc. 98 (1985), 117128], and by Kalmbach in her book to derive G...

Although heightened throughout childhood and adolescence, sweet taste preference declines during late adolescence (Desor et al., 1977; Desor and Beauchamp, 1987). Despite such age-related changes in sweet preferences, individual variation, due to both genetics (Bartoshuk, 2000) and experience (Beauchamp and Moran, 1982, 1984), exists at both ends of the age spectrum (Desor et al., 1977; Beaucha...
