Background The dearth of health workers in rural settings in Lao People’s Democratic Republic (PDR) and other developing countries limits healthcare access and outcomes. In evaluating non-wage financial incentive packages as a potential policy option to attract health workers to rural settings, understanding the expected costs and effects of the various programs ex antecan assist policy-makers ...

Associating distinct groups of objects (clusters) with contiguous regions of high probability density (high-density clusters), is a central assumption in statistical and machine learning approaches for the classification of unlabelled data. In unsupervised classification this cluster definition underlies a nonparametric approach known as density clustering. In semi-supervised classification, cl...

These membranes are usually prepared using interfacial polymerization. Hydrophobic diamine and water-soluble chloride salt precursor are reacted to form a thin polyamide (PA) separation layer on a porous support [1]. The PA cross-linking density has a...

The strength of entanglement present in a tubular structure consisting of short vortex flow filaments is assessed using a periodic boundary condition (PBC) model by employing the magnitude of the eigenvalues of the periodic linking matrix associated to the filamental structure. The effects of tube radius and of the alignment of the filaments on the strength of entanglement are shown to suggest ...

Treatment of diseases on the molecular level by genetic material is limited by effective delivery mechanisms. We focused on the synthesis of a pH-sensitive gene delivery vehicle based on dimethylaminoethyl methacrylate (DMAEMA) with tunable swelling, cross-linking density, and DNA release kinetics within the endosomal pH range. Our strategy, which utilized a single step for DNA encapsulation, e...

We consider Benham's model for strand separation in negatively supercoiled circular DNA, and study denaturation as function of the linking difference density kappa<0. We propose a statistical version of this model, based on bayesian segmentation methods of current use in bioinformatics; this leads to new algorithms with priors adapted to supercoiled DNA, taking into account the random nature of...
