Computational Chemotaxis in Ants and Bacteria over Dynamic Environments
Vitorino Ramos, C. M. Fernandes, A. C. Rosa +1
Chemotaxis can be defined as an innate behavioural response by an organism to a directional stimulus, in which bacteria, and other single-cell or multicellular organisms direct the…
Sheaves as modules
Pedro Resende, Elias Rodrigues
We revisit sheaves on locales by placing them in the context of the theory of quantale modules. The local homeomorphisms are identified with the Hilbert -modules that…
On two-Dimensional Holonomy
Joao Faria Martins, Roger Picken
We define the thin fundamental categorical group of a based smooth manifold as the categorical group whose objects are rank-1 homotopy classes of base…
Relating multichannel scattering and production amplitudes in a microscopic OZI-based model
Eef van Beveren, George Rupp
Relations between scattering and production amplitudes are studied in a microscopic multichannel model for meson-meson scattering, with coupling to confined quark-antiquark channel…
Generic dynamics of 4-dimensional C2 Hamiltonian systems
Mario Bessa, Joao Lopes Dias
We study the dynamical behaviour of Hamiltonian flows defined on 4-dimensional compact symplectic manifolds. We find the existence of a C2-residual set of Hamiltonians for which ev…
Invariants of Welded Virtual Knots Via Crossed Module Invariants of Knotted Surfaces
Louis H. Kauffman, João Faria Martins
We define an invariant of welded virtual knots from each finite crossed module by considering crossed module invariants of ribbon knotted surfaces which are naturally associated wi…
Type II and heterotic one loop string effective actions in four dimensions
Filipe Moura
We analyze the reduction to four dimensions of the R^4 terms which are part of the ten-dimensional string effective actions, both at tree level and one loop. We show that there are…
