Defect size distributions play an important role in process characterization and yield prediction. To determine efficient procedures to extract defect size distributions, a data base was set up that consists of hundreds of defect images to provide defect size distributions also reflecting irregular outlines of defects. Further investigation results that even a single extension value per defect ...

We present here a novel, cost-effective method for increasing and controlling the ortho-para H2 (o-p H2) conversion yield. First, we invoke two processes derived from fundamental, surface science insights, based on the effect of molecular orientation on the hydrogen-solid surface reaction, i.e., dynamical quantum filtering and steering, and apply them to enhance the o-p H2 conversion yield. Sec...

Previous work has demonstrated that combining mechanical vibration with magnetic interactions can result in the self-assembly of complex structures, albeit at low yield. Here we introduce a system where the yield of self-assembled structures is quantitatively predicted by a theoretical analysis. Millimeter-sized magnetic blocks, designed to form chains as their minimal energy state, are placed ...

Background In current practice, the diagnostic yield of endomyocardial biopsy is low because the procedure is performed ‘blind’ using X-ray fluoroscopy guidance and because many pathologies affect the myocardium in a patchy distribution. We hypothesized that biopsy performed under direct realtime MRI guidance would have superior diagnostic yield, in an animal model of focal myocardium pathology.

BACKGROUND Variations in sugar yield due to genotypic qualities of feedstock are largely undescribed for pilot-scale ethanol processing. Our objectives were to compare glucose and xylose yield (conversion and total sugar yield) from straw of five winter wheat cultivars at three enzyme loadings (2.5, 5 and 10 FPU g-1 dm pretreated straw) and to compare particle size distribution of cultivars aft...
