background: respiratory diseases cause a considerable amount of morbidity and mortality in the world. pulmonary function tests are important measures for the diagnosis and management of respiratory disorders. workers in tile and ceramic industry are exposed to high amounts of respiratory pollutants. objective: to identify the changes in spirometric parameters in a 2-year period among tile and c...

While the theoretical implications of models of DNA tile self-assembly have been extensively researched and such models have been used to design DNA tile systems for use in experiments, there has been little research testing the fundamental assumptions of those models. In this paper, we use direct observation of individual tile attachments and detachments of two DNA tile systems on a mica surfa...

PURPOSE This study was performed to determine the optimal tile size for the fractal dimension of the mandibular trabecular bone using a tile counting method. MATERIALS AND METHODS Digital intraoral radiographic images were obtained at the mandibular angle, molar, premolar, and incisor regions of 29 human dry mandibles. After preprocessing, the parameters representing morphometric characterist...

Experiments have demonstrated that DNA molecules can compute like a machine to solve mathematical problems, which is significant because of their parallel computation ability. However, due to the nature of biochemical reactions, DNA computation suffers from errors, which are its main limitation. The abstract and kinetic Tile Assembly Models are now commonly used to simulate real DNA computing e...

We discuss the self-assembly system of triangular tiles instead of square tiles, in particular right triangular tiles and equilateral triangular tiles. We show that the triangular tile assembly system, either deterministic or non-deterministic, has the same power to the square tile assembly system in computation, which is Turing universal. By providing counter-examples, we show that the triangu...

Over the last de ade, a dramati in rease has been observed in the ability to generate and store data in the ourse of parameter studies, performan e analysis, and software testing. In this paper, we introdu e ZENTURIO, a sophisti ated experiment management environment that greatly alleviates parameter studies, performan e analysis, and software testing for a wide variety of target ar hite tures,...

ABSTRACT We present a method for lustering do uments and extra ting topi words of ea h luster using a probabilisti graphi al model. We maximize the likelihood of the model with the Expe tation Maximization algorithm. Our experiments demonstrate that the latent variables of the model an be seen as lusters of do uments and terms.

Highly conductive free standing polypyrrole (PPy) films were prepared by a novel freezing interfacial polymerization method. The films exhibit metallic luster and electrical conductivity up to 2000 S cm(-1). By characterizing with SEM, FTIR, Raman and XRD, the high conductivity is attributed to the smooth surface, higher conjugation length and more ordered molecular structure of PPy.
