FiFoSiM - an integrated tax benefit microsimulation and CGE model for Germany
No full textThis paper describes FiFoSiM, the integrated tax benefit microsimulation and computable general equilibrium (CGE) model of the Center of Public Economics at the University of Cologne. FiFoSiM consists of three main parts. The first part is a static tax benefit microsimulation module. The second part adds a behavioural component to the model; an econometrically estimated labour supply model. The third module is a CGE model which allows the user of FiFoSiM to assess the global economic effects of policy measures. Two specific features distinguish FiFoSiM from other tax benefit models: First, the simultaneous use of two databases for the tax benefit module and second, the linkage of the tax benefit model to a CGE model.FiFoSiM; microsimulation; CGE
Nailfold capillaroscopy pattern recognition using texture analysis
No full textNailfold capillaroscopy (NC) is a non-invasive imaging technique employed to assess the condition of blood capillaries in the nailfold. It is particularly useful for early detection of scleroderma spectrum disorders and evaluation of Raynaud's phenomenon. While diagnosis based on NC is typically performed by manual inspection, computerised nailfold capillaroscopy can help to reduce the inherent ambiguity present in human judgement while greatly reducing the time for diagnosis. Diagnosis of NC images involves the recognition of early, active and late patterns, also known as NC patterns or scleroderma (SD) patterns, in the images. In this paper, we propose a holistic method to classify NC images in these well known patterns. In particular, we employ texture analysis to describe the underlying patterns, coupled with a classifier to first identify patterns in fingers, and then, through a voting strategy, reach a decision for a patient. Experimental results on a set of NC images with known ground truth demonstrate the efficacy of our approach
Breakdown of Traditional Many-Body Theories for Correlated Electrons
No full textStarting from the (Hubbard) model of an atom, we demonstrate that the uniqueness of the mapping from the interacting to the noninteracting Green function, G -> G(0), is strongly violated, by providing numerous explicit examples of different G(0) leading to the same physical G. We argue that there are indeed infinitely many such G(0), with numerous crossings with the physical solution. We show that this rich functional structure is directly related to the divergence of certain classes of (irreducible vertex) diagrams, with important consequences for traditional many-body physics based on diagrammatic expansions. Physically, we ascribe the onset of these highly nonperturbative manifestations to the progressive suppression of the charge susceptibility induced by the formation of local magnetic moments and/or resonating valence bond (RVB) states in strongly correlated electron systems
Integrating habitat concerns into Gordon-Schaefer model
No full textIn the Gordon-Schaefer model (G-S model), widely used to design fisheries management policy, only resource stock dynamic is considered and carrying capacity is constant. We propose an extension to the G-S model that incorporates the dynamics of carrying capacity as an indicator of dynamics of the marine habitats. The study yields two main findings. First, we demonstrate that habitats matter, by showing that the main outcomes of the G-S model are dramatically modified if habitats are included in the analysis. Second, through a heuristic model and simulations, we show, for the first time, that our extended model provides an appropriate framework to analyse the putative contribution of MPAs and ARs. The model presented in this article opens the way to a better understanding of the benefits of MPAs and ARs, as well as other habitat protection policies.Bioeconomics, Gordon-Schaefer model, Marine habitats, Artificial reefs
