The extraction of consistent skeletons in the presence of boundary noise is still a problem for most skeletonization algorithms. Many suppress skeletons associated with boundary perturbation, either by preventing their formation or removing them subsequently using additional operations. A more appropriate approach is to view a shape as comprising of structural and textural skeletons. The former...

Abstract Three new compounds ( 1 – 3 ) with unusual skeletons were isolated from the n -hexane extract of air-dried aerial parts Hypericum scabrum . Compound represents first example an esterified polycyclic polyprenylated acylphloroglucinol that features a unique tricyclo-[4.3.1.1 1,4 ]-undecane skeleton. 2 is fairly simple MPAP, but unexpected cycloheptane ring decorated prenyl substituents, ...

This report presents a survey of performance models for parallel al-gorithmic skeletons. First, higher-order functions (HOFs) are presented according to the modelled skeletons. Next, the corresponding parallel implementations (skeletons) for the HOFs are discussed with the performance models that were constructed for the skeletons.

conclusions atypical chickenpox infections should be suspected in any patient who presents unexplained abdominal pain, fever, and dyspnea, even if cutaneous lesions are minimal. an early diagnosis can prevent a fatal outcome. introduction infection with varicella-zoster virus (vzv) in healthy adults tends to be more severe. antiviral medication (often prescribed for adults), is effective in red...
