plant growth regulators (pgrs) are widely used for lodging control in winter wheat (triticum aestivum l.) grown at high n rates. although the introduction of semi-dwarf wheat cultivars had largely solved the problem of lodging, evidence was already accumu-lating that the timely application of a growth retardant such as chlormequat (ccc) or ethephon could increase the grain yield of wheat, by th...

This vignette is intended to give a short introduction into the methods of the qualityTools package. The qualityTools package contains methods associated with the Define Measure Analyze Improve and Control (i.e. DMAIC) problem solving cycle of the Six Sigma Quality Management methodology. Usage of these methods is illustrated with the help of artificially created datasets. • Define: Pareto Char...

Resistance of ovarian clear cell carcinoma (CCC) to platinum-based chemotherapy is associated with poor prognosis, and an effective treatment for advanced disease is urgently needed. HER2/neu is up-regulated more often in CCC than in other histologic types of epithelial ovarian cancer. The purpose of this study was to assess possible treatment for ovarian CCC with the anti-HER2 antibody trastuz...

BACKGROUND We aimed to evaluate the function of coronary collateral circulation (CCC) in the ischemic myocardium by a two-dimensional strain technique. METHODS AND RESULTS Myocardial segments for all patients were divided into three groups: no coronary collateral circulation (NCCC), CCC, and normal control. We obtained the segmental strain and the strain rate in longitudinal, radial, circumfe...

A simple algorithm is introduced for computing the run length distribution of a monitoring scheme combining a Shewhart chart with an Exponentially Weighted Moving Average control chart. The algorithm is based on the numerical approximation of the integral equations and integral recurrence relations related to the run-length distribution. In particular, a modified Clenshaw-Curtis quadrature rule...

Inventory replenishment rules contribute significantly to the bullwhip effect and inventory instability in supply chains. Smoothing replenishment rules have been suggested as a mitigation solution for the bullwhip effect but dampening the bullwhip effect might increase inventory instability. This paper evaluates a real-time inventory replenishment system denoted as SPC that utilizes a control c...
