Identification of a minimal microsatellite marker panel for the fingerprinting of peach and nectarine cultivars
Rojas,Gabriela; Méndez,Marco A; Mu?oz,Carlos; Lemus,Gamalier; Hinrichsen,Patricio;
Electronic Journal of Biotechnology , 2008,
Abstract: the genetic characterization of 117 peach and nectarine cultivars (prunus persica (l.) batsch) using microsatellite (ssr) markers is presented. analyzed genotypes include the complete list of cultivars under intellectual property (ip) protection in chile. one hundred and two out of the 117 cultivars under study could be identified using only 7 ssrs. other 5 cultivars were differentiated using 3 additional markers, but 5 pairs of genotypes were not differentiable. the average expected heterozygosity for the set of markers was 0.55, ranging from 0.28 in bppct-008 to 0.81 in cppct-022, with an f value of 0.37. a neighbor-joining dendrogram showed that, with few exceptions, peaches and nectarines clustered separately. these results are the basis for the development of a fingerprinting protocol for the unequivocal identification of most of the peach and nectarine cultivars officially registered in chile.
On possible experimental realizations of directed percolation
Hinrichsen, Haye;
Brazilian Journal of Physics , 2000, DOI: 10.1590/S0103-97332000000100007
Abstract: directed percolation is one of the most prominent universality classes of nonequilibrium phase transitions and can be found in a large variety of models. despite its theoretical success, no experiment is known which clearly reproduces the critical exponents of directed percolation. the present work compares suggested experiments and discusses possible reasons why the observation of the critical exponents of directed percolation is obscured or even impossible.

Abstract: Die klassische visuelle Anthropologie hat in den letzten Jahren einen zunehmenden Paradigmenwechsel erfahren. Mehr und mehr bemühen sich KünstlerInnen und EthnologInnen um Zusammenarbeit und um das Aufbrechen der starren Grenzen zwischen den Disziplinen. Der hier besprochene Band widmet sich in dreizehn Beitr gen von KünstlerInnen, EthnologInnen und KunstwissenschaftlerInnen den Herausforderungen von Kollaboration und Austausch. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1203254 Classic Visual Anthropology has most recently undergone a shift in paradigm. The discipline is now increasingly focused on the collaboration between artists, anthropologists and ethnographers to surmount the rigid borders separating the fields of science and art. The volume reviewed here dedicates its 13 contributions by artists, ethnologists, art historians and art critics to the challenge of mutual collaboration and dialogue.

Four State Models and Clifford Algebras
Haye Hinrichsen
Physics , 1994, DOI: 10.1088/0305-4470/27/16/008
Abstract: With appropriate boundary conditions the anisotropic $XY$ chain in a magnetic field is known to be invariant under quantum group transformations. We generalize this model defining a class of integrable chains with several fermionic degrees of freedom per site. In order to maintain the quantum group symmetry a general condition on the parameters of these systems is derived. It is shown that the corresponding quantum algebra is a multi-parameter deformation of the Clifford algebra. Discussing a special physical example we observe a new type of zero modes.
Matrix Product Ground States for Asymmetric Exclusion Processes with Parallel Dynamics
Haye Hinrichsen
Physics , 1995, DOI: 10.1088/0305-4470/29/13/030
Abstract: We show in the example of a one-dimensional asymmetric exclusion process that stationary states of models with parallel dynamics may be written in a matrix product form. The corresponding algebra is quadratic and involves three different matrices. Using this formalism we prove previous conjectures for the equal-time correlation functions of the model.
Stochastic Lattice Models with Several Absorbing States
Haye Hinrichsen
Physics , 1996, DOI: 10.1103/PhysRevE.55.219
Abstract: We study two models with n equivalent absorbing states that generalize the Domany-Kinzel cellular automaton and the contact process. Numerical investigations show that for n=2 both models belong to the same universality class as branching annihilating walks with an even number of offspring. Unlike previously known models, these models have no explicit parity conservation law.
A Generalized Duality Transformation of the Anisotropic Xy Chain in a Magnetic Field
Haye Hinrichsen
Physics , 1993, DOI: 10.1088/0305-4470/27/4/008
Abstract: We consider the anisotropic $XY$ chain in a magnetic field with special boundary conditions described by a two-parameter Hamiltonian. It is shown that the exchange of the parameters corresponds to a similarity transformation, which reduces in a special limit to the Ising duality transformation.
Dynamical response function of the disordered kinetic Ising model
Haye Hinrichsen
Physics , 2007, DOI: 10.1088/1742-5468/2008/02/P02016
Abstract: Recently Baumann et al. [arXiv:0709.3228v1] studied the phase-ordering kinetics of the two-dimensional Ising model with uniform spatially quenched disorder by Monte-Carlo simulations. They found that the two-time response and correlation functions are in agreement with the predictions of local scale invariance generalised to z!=2. The present paper shows why this is not true and suggests an alternative approach which leads to a much better agreement with the numerical results.
Ageing in homogeneous systems at criticality
Haye Hinrichsen
Physics , 2007,
Abstract: Ageing phenomena are observed in a large variety of dynamical systems exhibiting a slow relaxation from a non-equilibrium initial state. Ageing can be characterised in terms of the linear response R(t,s) at time t to a local perturbation at time s
