Grandparents constitute an important source of childcare to many parents. Focusing on the Belgian context, this paper improves our understanding decision-making by investigating how formal availability and grandparents affect arrangements. By means multinomial regression models we simultaneously model uptake informal Combining linked microdata from censuses with contextual data at level municip...

Natural fiber–reinforced polymer composites offer many advantages over conventional composite materials, such as availability, low cost, inexpensive, lightweight, and high specific mechanical properties. However, the applications of these materials are still limited due to challenges in achieving a good interface between fibers matrix. This is highly influenced by fiber surface characteristics ...

1. EXTENDED ABSTRACT Delay-tolerant Networking (DTN) [3] has moved a long way from its—for many probably somewhat elite—origin of a technology for an Interplanetary Internet in the late 1990s to an established research discipline. One major contributor to this trend was the observation that quite a few terrestrial networks exhibit delay-tolerant properties, albeit of different nature: from spar...

begin{abstract} the relations between the spectrum of the matrix $q+r$ and the spectra of the matrices $(gamma + delta)q+(alpha + beta)r-qr-rq$, $qr-rq$, $alpha beta r-qrq$, $alpha rqr-(qr)^{2}$, and $beta r-qr$ have been given on condition that the matrix $q+r$ is diagonalizable, where $q$, $r$ are ${alpha, beta}$-quadratic matrix and ${gamma, delta}$-quadratic matrix, respectively, of order $...

in this paper, we derive the necessary and sufficient conditions for the quaternion matrix equation xa=b to have the least-square bisymmetric solution and give the expression of such solution when the solvability conditions are met. futhermore, we consider the maximal and minimal inertias of the least-square bisymmetric solution to this equation. as applications, we derive sufficient and necess...

results migration of cells started on the fifth day. as a result of this migration, most cells were located on the surface of the scaffold and formed epiderm-like structure and some penetrated into the scaffold. by day 25, cells which had penetrated into the scaffold had various destinies such as becoming elongated spindle-shaped cells and creating blood vessel-like structures. conclusions adm ...

SUMMARY RadCon is a Macintosh program for manipulating and analysing phylogenetic trees. The program can determine the Cladistic Information Content of individual trees, the stability of leaves across a set of bootstrap trees, produce the strict basic Reduced Cladistic Consensus profile of a set of trees and convert a set of trees into its matrix representation for supertree construction. AVA...

UNLABELLED MatrixPlot is a program for making high-quality matrix plots, such as mutual information plots of sequence alignments and distance matrices of sequences with known three-dimensional coordinates. The user can add information about the sequences (e.g. a sequence logo profile) along the edges of the plot, as well as zoom in on any region in the plot. AVAILABILITY MatrixPlot can be obt...

service availability is important for any organization. this has become more important with the increase of dos attacks. it is therefore essential to assess the threat on service availability. we have proposed a new model for threat assessment on service availability with a data fusion approach. we have selected three more important criteria for evaluating the threat on service availability and...
