A variety of microbial communities and their genes (the microbiome) exist throughout the human body, with fundamental roles in human health and disease. The National Institutes of Health (NIH)-funded Human Microbiome Project Consortium has established a population-scale framework to develop metagenomic protocols, resulting in a broad range of… (More)
We present a method to tune software parameters using ideas from software testing and machine learning. The method is based on the key observation that for many classes of instances, the software shows improved performance if a few critical parameters have " good " values, although which parameters are critical depends on the class of instances. Our method… (More)
− DeviceNet and ControlNet are two well-known idus-trial networks based on the CIP protocol (CIP = Control an Information Protocol). Both networks have been developed by Rockwell Automation, but are now owned and maintained by the two manufacturers organizations ODVA (Open DeviceNet Vendors Association, see http://www.odva.org) and ControlNet International… (More)
The stoichiometric reaction between thiols and maleimide-functional poly(ester)s is demonstrated to be a quantitative, tolerant, mild and efficient method for polymer modification.
An Artificial Neural Network (ANN) is a computational modeling tool which has found extensive acceptance in many disciplines for modeling complex real world problems. An ANN can model problems through learning by example, rather than by fully understanding the detailed characteristics and physics of the system. In the present study, the accuracy and… (More)

For the GLS and Bjorken DIS sum rules we compare fixed-order NNLO perturbative QCD estimates, and all-orders resummed estimates, with the available data, in order to assess the reliability of fixed-order perturbation theory at rather small Q 2 values. Fits are also performed for non-perturbative power corrections using a recently proposed model.
A Nycodenz gradient technique is described which permits the separation of functionally active polymorphonuclear neutrophils (PMN) from the peripheral blood of rats. PMN are obtained at greater than 90% purity and fractionate at a peak density of 1.0919 g/ml. The method is suitable for isolating PMN when the circulating PMN count is low (less than 20%) as… (More)
We consider the leading one-chain term in a skeleton expansion for QCD observables and show that for energies Q 2 > Λ 2 , where Q 2 = Λ 2 is the Landau pole of the coupling, the skeleton expansion result is equivalent to the standard Borel integral representation, with ambiguities related to infrared (IR) renormalons. For Q 2 < Λ 2 the skeleton expansion… (More)
