Cauchy-Compact flat spacetimes with BTZ singularities [PDF]
arXiv, 2016 The zoology of singularities for Lorentzian manifold is slightly more complicated than for Riemannian manifolds. Our present work study Cauchy-compact globally hyperbolic singular flat spacetimes with extreme BTZ-like singular lines. We use the notion of BTZ-extension of a singular spacetime introduced in a previous paper to give a description of ...

Graph clustering, variational image segmentation methods and Hough transform scale detection for object measurement in images [PDF]
, 2016 We consider the problem of scale detection in images where a region of interest is present together with a measurement tool (e.g. a ruler). For the segmentation part, we focus on the graph based method by Flenner and Bertozzi which reinterprets classical continuous Ginzburg-Landau minimisation models in a totally discrete framework.

Nature, 1870 A BOOK such as this aims at being was wanted—one which should give a little more of systematic detail than is to be found in Professor Huxley's “Outlines” or Professor Rolleston's introductory chapters of his “Forms.” It required, however, a man of ...

Fitting analysis provides further evidence for eradication of hiv/aids infection under combined liposome drug delivery treatment [PDF]
Drug Delivery Systems and Sciences (UK). 2003, volume 3, No 2, pp.
49-51, 2007 It is now evident that the commonly accepted strategy for treatment of HIV/AIDS by highly active antiretroviral therapy (HAART) will not lead to eradication of HIV in a reasonable time. This is straightforward from the typical exponential viral load decay upon treatment revealing initial considerable but incomplete reduction of plasma HIV RNA with ...

Efficiency of cyclic devices working with non-Boltzmannian fluids: challenging the second principle of thermodynamics [PDF]
arXiv, 2011 According to classical Boltzmannian thermodynamics, the efficiency of a cyclic machine is strictly lower than one. Such a result is a straightforward consequence of the second principle of thermodynamics. Recent advances in the study of the thermodynamics of long-range interacting system report however on a rather intricate zoology of peculiar ...

Zoology in the Hénon family: twin babies and Milnor's swallows [PDF]
arXiv, 2018 We study $C^{d,r}$-H\'enon-like families $(f_{a\, b})_{a\, b}$ with two parameters $(a,b)\in \mathbb R^2$. We show the existence of an open set of parameters $(a,b)\in \mathcal D$, so that a renormalization chart conjugates an iterate of $f_{a\, b}$ to a perturbation of $(x,y)\mapsto ((x^2+c_1)^2+c_2,0)$.

Automatic acoustic identification of individual animals: Improving generalisation across species and recording conditions [PDF]
arXiv, 2018 Many animals emit vocal sounds which, independently from the sounds' function, embed some individually-distinctive signature. Thus the automatic recognition of individuals by sound is a potentially powerful tool for zoology and ecology research and practical monitoring.
