Abstract Background As the use of nanopore sequencing for metagenomic analysis increases, tools capable performing long-read taxonomic classification (ie. determining composition a sample) in fast and accurate manner are needed. Existing were either designed short-read data (eg. Centrifuge), take days to analyse modern sequencer outputs MetaMaps) or suffer from suboptimal accuracy CDKAM). Addit...

This report describes the development of a hand-powered centrifuge to determine hematocrit values in low-resource settings. A hand-powered centrifuge was constructed by using a salad spinner. Hematocrit values were measured by using the hand-powered device, and results were compared with those of a benchtop centrifuge. The packed cell volume (PCV) measured with the hand-powered device correlate...

Purpose The purpose of this study was to evaluate the effect of gravity acceleration on choroidal and retinal nerve fiber layer (RNFL) thickness using swept-source optical coherence tomography (SS-OCT). Methods Thirteen healthy volunteers who planned to participate in human centrifuge training as part of the flight surgeon selection process enrolled this study. During centrifuge training, gra...

The standard centrifuge method has been frequently used to measure vulnerability to xylem cavitation. This method has recently been questioned. It was hypothesized that open vessels lead to exponential vulnerability curves, which were thought to be indicative of measurement artifact. We tested this hypothesis in stems of olive (Olea europea) because its long vessels were recently claimed to pro...

In this, paper we present a probabilistic approach to analysis and prediction of protein structure. We argue that this approach provides a flexible and convenient mechanism to perform general scientific data analysis in molecular biology. We apply our approach to an important problem in molecular biology-predicting the secondary structure of proteins-and obtain experimental results comparable t...

The removal of bacterial populations from large volumes of liquid culture media may be accomplished readily using a centrifuge, but the usual efficient continuous-feed type of centrifuge is often large and expensive. In this laboratory, during the past 2 years, bacterial cells have been removed from liquid culture with considerable success, using a small, inexpensive, continuously fed centrifug...

The theory of secondary convergence and entropy has had interesting results in the comparative linguistics Semitic languages, as studies Lutz Edzard who analyzed between various languages once they were already distinguished from one another separate branches deriving Proto-Semitic. However, Edzard’s contribution to issue regards only same family, a relatively small language family integrated l...
