Atmospheric pressure non equilibrium plasma treatments have been implemented to produce solvent-free Poly-L-lactic acid (PLLA) scaffolds, to improve biocompatibility of PLLA mats and to increase electrolyte uptake of Poly(vinylidene fluoride) (PVDF) separators for lithium batteries. It has been observed that plasma treatments are a suitable way to improve polymeric solution electrospinnability,...

The paper presents an entropy-based approach to segment a corpus into words, when no additional information about the corpus or the language, and no other resources such as a lexicon or grammar are available. To segment the corpus, the algorithm searches for separators, without knowing a priory by which symbols they are constituted. Good results can be obtained with corpora containing "clearly ...

Unichord-free graphs are defined as having no cycle with a unique chord. They have appeared in several papers recently and are also characterized by minimal separators always inducing edgeless subgraphs (in contrast to characterizing chordal graphs by minimal separators always inducing complete subgraphs). A new characterization of unichord-free graphs corresponds to a suitable reformulation of...

Separators are needed in microbial fuel cells (MFCs) to reduce electrode spacing and preventing electrode short circuiting. The use of nylon and glass fiber filter separators in single-chamber, aircathode MFCs was examined for their effect on performance. Larger pore nylon mesh were used that had regular mesh weaves with pores ranging from 10 to 160 mm, while smaller pore-size nylon filters (0....

This paper describes a novel algorithm for the unsupervised learning of word separators in raw text. The algorithm requires no language-specific knowledge regarding the text being processed. It relies solely on distributional properties of the text and uses the minimum description length (MDL) principle in order to partition characters into two subsets that correspond well with the traditional ...

Most state-of-the-art ordering schemes for sparse matrices are a hybrid of a bottom-up method such as minimum degree and a top down scheme such as George’s nested dissection. In this paper we present an ordering algorithm that achieves a tighter coupling of bottom-up and topdown methods. In our methodology vertex separators are interpreted as the boundaries of the last elements in a bottom-up o...
