We empirically evaluate several state-of-theart methods for constructing ensembles of heterogeneous classifiers with stacking and show that they perform (at best) comparably to selecting the best classifier from the ensemble by cross validation. We then propose a new method for stacking, that uses multi-response model trees at the meta-level, and show that it clearly outperforms existing stacki...

The structure of 2,3,6,7,10,11-hexahydroxytriphenylene (hhtp) methanol monosolvate, C18H12O6·CH3OH, has triclinic symmetry (space group P-1). The compound has a three-dimensional layered network structure formed by intermolecular hydrogen bonding. Structure analysis with Hirshfeld surfaces is shown to be a sensitive method for comparing π-stacking effects in the five known solvates of hhtp. The...

3D integration is a promising advanced manufacturing process offering a variety of new hardware security protection opportunities. This paper presents a way of securing 3D ICs using Hamiltonian paths as hardware integrity verification sensors. As 3D integration consists in the stacking of many metal layers, one can consider surrounding a security-sensitive circuit part by a wire cage. After exp...

The application of the weak-beam method of electron microscopy to the measurement of the separation of partial dislocations 2 2.0 nrn is discussed. The accuracy of the experimental results is analysed, and approximations in obtaining values of the stacking-fault energy, y, are outlined.

1) Out corpus of descriptive text contains a significant number of long-distance pronominal references (8.4% of the total). In order to account for how these pronouns are interpreted, we re-examine Grosz and Sidner's theory of the attentional state, and in particular the use of the global focus to supplement centering theory. Our corpus evidence concerning these long-distance pronominal referen...

In this paper we describe a framework for the construction of entities that can serve as interpretations of arbitrary contiguous chunks of text An important part of the paper is devoted to describing stacking cells the proposed meanings for bracket structures

In greening maize mesophyll, circular dichroism (c.d.) revealed the early formation of protein-chlorophyll complexes, followed by unorganized chlorophyll. The intense c.d. [Gregory & Raps (1974) Biochem. J. 142, 193-201] appeared later still, whereas membrane-membrane contact (stacking), measured from electron micrographs, appeared much earlier. Isolated grana, which still showed stacking, lost...

This paper presents our approach of identifying the profile of an unknown user based on the activities of known users. The aim of author profiling task of PAN@CLEF 2016 is cross-genre identification of the gender and age of an unknown user. This means training the system using the behavior of different users from one social media platform and identifying the profile of other user on some differ...

Some recent literature has concluded that patent remedies result in systematically excessive royalties because of holdup and stacking problems. This article shows that this literature is mistaken. The royalty rates predicted by the holdup models are often (plausibly most of the time) below the true optimal rate. Further, those predicted royalty rates are overstated because of incorrect assumpti...

Stacking procedures with the objective of improvement of signal to noise ratio were in use before the introduction of Common reflection point stacking introduced by Mayne in 1962. But, these techniques were problematic, at times, because they used reflections from a portion of reflectors that were too large. Hence, stacking tends to obscure the very detail of reflector which is being sought. So...
