By charge neutralization of carboxylic acid groups in graphene oxide (GO) with Cs(2)CO(3) to afford Cesium-neutralized GO (GO-Cs), GO derivatives with appropriate modification are used as both hole- and electron-extraction layers for bulk heterojunction (BHJ) solar cells. The normal and inverted devices based on GO hole- and GO-Cs electron-extraction layers both outperform the corresponding sta...

Some natural language processing tasks can be learned from example corpora, but having enough examples for the task at hands can be a bottleneck. In this work we address how Wikipedia and DBpedia, two freely available language resources, can be used to support Named Entity Recognition, a fundamental task in Information Extraction and a necessary step of other tasks such as Co-reference Resoluti...

This report proposes a new image segmentation method with a multi-resolution mechanism. In this method, the high accuracy on image edge extraction and image texture evaluation is realized. The proposed method employs the edge extraction based on the average values of intensities in a small image part and also the texture evaluation based on the co-occurrence probability of a local image area. I...

a simple, highly sensitive, accurate and selective method for determination of trace amounts of co(ii) in water samples is presented. isocyanate treated graphite oxides (igos) solid phase extraction adsorbent was synthesized by covalently isocyanate onto the surfaces of graphite oxides. the stability of a chemically (igos) especially in concentrated hydrochloric acid which was then used as a re...

This indirect method for determination of desferrioxamine (DFO, deferoxamine, Desferal) and its chelated compounds ferrioxamine (FO) and aluminoxamine (AIO) in biological fluids involves metal chelate formation and solvent extraction, the metal being determined by Zeeman atomic absorption spectrometry (Zeeman-AAS). Special attention was paid to the pH and recovery of extraction, iron-aluminum i...

The availability of online text documents exposes readers to a vast amount of potentially valuable knowledge buried therein. The sheer scale of material has created the pressing need for automated methods of discovering relevant information without having to read it all. Hence the growing interest in recent years in Text Mining. A common approach to Text Mining is Information Extraction (IE), e...

We present a bolus method of inert-gas delivery to the lungs that facilitates application of multiple inert gases and the multiple inert-gas-exchange technique (MIGET) model to noninvasive measurements of cardiac output (CO) and central mixed venous oxygen content Reduction in recirculation error is made possible by 1) replacement of sinusoidal input functions with impulse inputs and 2) replace...
