Physical performance of a positron tomograph for brain imaging with retractable septa
Performance characteristics of a new design of positron tomograph with automatically retractable septa for brain imaging have been studied. The device, consisting of block BGO d...
Area and length minimizing flows for shape segmentation
A number of active contour models have been proposed that unify the curve evolution framework with classical energy minimization techniques for segmentation, such as snakes. The...
Updating the MISEV minimal requirements for extracellular vesicle studies: building bridges to reproducibility
On separation of EVs (also referred to as isolation, purification or concentration), MISEV2014 acknowledged that there is no consensus on an “optimal” method, such as ultracentr...
Fully three-dimensional reconstruction for a PET camera with retractable septa
A fully 3-D reconstruction algorithm has been developed to reconstruct data from a 16 ring PET camera (a Siemens/CTI 953B) with automatically retractable septa. The tomograph is...
An empirical study of contemporary beliefs about work in American society.
The underlying concepts or beliefs people hold about work were studied by first developing a conceptual framework consisting of five different belief systems. The framework was ...
On the Dislocation Theory of Plastic Deformation
A detailed study has been made of the lattice imperfections which are assumed to account for plastic deformation. Calculations of the strain energy associated with these disloca...
Complete Sequence of the Mitochondrial DNA of the Red Alga <i>Porphyra purpurea</i>: Cyanobacterial Introns and Shared Ancestry of Red and Green Algae
The mitochondrial DNA (mtDNA) of Porphyra purpurea, a circular-mapping genome of 36,753 bp, has been completely sequenced. A total of 57 densely packed genes has been identified...
Overlapping Communities Explain Core–Periphery Organization of Networks
Networks provide a powerful way to study complex systems of interacting objects. Detecting network communities-groups of objects that often correspond to functional modules-is c...
An emerging consensus on grading recommendations?
Clinical practice guidelines have improved in quality over the past 10 years by adhering to a few basic principles, such as conducting thorough systematic reviews of relevant ev...
Improving the use of research evidence in guideline development: 9. Grading evidence and recommendations
Should WHO grade the quality of evidence and the strength of recommendations? Users of recommendations need to know how much confidence they can place in the underlying evidence...
