Despite 180 years of theory on magnetism, it appears that the practice of calculating forces on magnetic media is ambiguous, as illustrated by a recent article by Casperson [1]. Potentially troubling issues include: Which field B or H should be used? Should the total field be used, or only the external field? And if the latter, what is meant by “external”? Can/should effects of magnetization cu...

background and objectives: alzheimer's disease (ad) as a neurodegenerative disorder is the most common form of dementia in the elderly. according to the amyloid hypothesis, accumulation of amyloid beta (aβ) plaques, which are mostly constituted of aβ peptide aggregates, triggers pathological cascades that lead to neuronal cell death. thus, modulation of aβ toxicity is the hopeful therapeut...

Chinese cherry (Cerasus pseudocerasus (Lindl.) G.Don) is an economically important tetraploid fruiting species native to China. Simple sequence repeats (SSRs)—due their codominance, polymorphism, and stability—have been widely applied in genetic identification trait-association analysis. In this study, using comparative genomics strategy the data of one high-quality whole genome seven prelimina...
