Experiments in small aspect-ratio Taylor–Couette flows have reported the presence of a band in parameter space where rotating waves become steady nonaxisymmetric solutions (a pinning effect) via infinite-period bifurcations. Previous numerical simulations were unable to reproduce these observations. Recent additional experiments suggest that the pinning effect is not intrinsic to the dynamics o...

Several key results for set packing problems do not seem to be easily or even possibly transferable to set covering problems, although the symmetry between them. The goal of this paper is to introduce a nonidealness index by transferring the ideas used for the imperfection index defined by Gerke and McDiarmid [Graph imperfection, J. Combin. Theory Ser. B 83 (2001) 58–78]. We found a relationshi...

Neck retardation in stretching of ductile materials is promoted by strain hardening, strain-rate hardening and inertia. Retardation is usually beneficial because necking is often the precursor to ductile failure. The interaction of material behavior and inertia in necking retardation is complicated, in part, because necking is highly nonlinear but also because the mathematical character of the ...

The process of land cover change prediction is generally subjected to several types of imperfections which affect the reliability of decision about these changes. Several works in literature are carried out in an attempt to mitigate the issues caused by data related imperfections. Although new prediction models are created and improvement is done for the existing ones, both the imperfection rel...

This longitudinal study investigates whether finding benefits in cancer can be predicted by assimilative and accommodative coping strategies, general self-efficacy, and received social support. Self-efficacy and social support were measured 1 month after cancer surgery, coping strategies 6 months after surgery, and benefit finding 12 months after surgery. Ninety-seven patients with cancer compl...

Accurate scatterometry and ellipsometry characterization of non-perfect thin films and nanostructured surfaces are challenging. Imperfections like surface roughness make the associated modelling and inverse problem solution difficult due to the lack of knowledge about the imperfection on the surface. Combining measurement data from several instruments increases the knowledge of non-perfect surf...
