In the particular version obtained when \chi = 2 , ( \star ) was proposed in [31] as a model for crime propagation in urban regions. Within a suitable generalized framework, it is shown that under mild assumptions on the parameter functions and the initial data the no-flux initial-boundary value problem for ( \star ) possesses at least one global solution in the case when all model ingredients are radially symmetric with respect to the center of Ω . Moreover, under an additional hypothesis on stabilization of the given external source terms in both equations, these solutions are shown to approach the solution of an elliptic boundary value problem in an appropriate sense. The analysis is based on deriving a priori estimates for a family of approximate problems, in a first step achieving some spatially global but weak initial regularity information which in a series of spatially localized arguments is thereafter successively improved. To the best of our knowledge, this is the first result on global existence of solutions to the two-dimensional version of the full original system ( \star ) for arbitrarily large values of χ . }}, author = {{Winkler, Michael}}, issn = {{0294-1449}}, journal = {{Annales de l'Institut Henri Poincaré C, Analyse non linéaire}}, number = {{6}}, pages = {{1747--1790}}, publisher = {{European Mathematical Society - EMS - Publishing House GmbH}}, title = {{{Global solvability and stabilization in a two-dimensional cross-diffusion system modeling urban crime propagation}}}, doi = {{10.1016/j.anihpc.2019.02.004}}, volume = {{36}}, year = {{2019}}, } @article{63363, abstract = {{ This work is concerned with a prototypical model for the spatio-temporal evolution of a forager–exploiter system, consisting of two species which simultaneously consume a common nutrient, and which interact through a taxis-type mechanism according to which individuals from the exploiter subpopulation move upward density gradients of the forager subgroup. Specifically, the model [Formula: see text] for the population densities [Formula: see text] and [Formula: see text] of foragers and exploiters, as well as the nutrient concentration [Formula: see text], is considered in smoothly bounded domains [Formula: see text], [Formula: see text]. It is first shown that under an explicit condition linking the sizes of the resource production rate [Formula: see text] and of the initial nutrient concentration, an associated Neumann-type initial-boundary value problem admits a global solution within an appropriate generalized concept.

Consequently, the provision of means to quantify the performance of current question answering approaches on current datasets has become ever more important. However, a large percentage of the queries found in popular question answering benchmarks cannot be executed on current versions of their reference dataset. There is a consequently a clear need to curate question answering benchmarks periodically. However, the manual alteration of question answering benchmarks is often error-prone. We alleviate this problem by presenting QUANT, a novel framework for the creation and curation of question answering benchmarks. QUANT sup-ports the curation of benchmarks by generating smart edit suggestions for question-query pair and for the corresponding metadata. In addition, our framework supports the creation of new benchmark entries by pro-viding predefined quality checks for queries. We evaluate QUANT on 653questions obtained from QALD-1 to QALD-8 with 10 users. Our results show that our framework generates reliable suggestions and can reduce the curation effort for QA benchmarks by up to 91%.}}, author = {{Gusmita, Ria Hari and Jalota, Rricha and Vollmers, Daniel and Reineke, Jan and Ngonga Ngomo, Axel-Cyrille and Usbeck, Ricardo}}, booktitle = {{Semantic Systems.
