Magnetite nanocrystals have been widely used in many fields. Recently, a new magnetite nanocrystals, called magnetosome, has been found in magnetotactic bacteria. In this article, we researched on the properties of magnetosomes in detail, such as crystalline, morphology, crystal-size distributions, vitro cytotoxicity, and magnetic properties and quantified(More)
Working memory plays an important role in human cognition. This study investigated how working memory was encoded by the power of multi-channel local field potentials (LFPs) based on sparse nonnegative matrix factorization (SNMF). SNMF was used to extract features from LFPs recorded from the prefrontal cortex of four Sprague-Dawley rats during a memory task(More)
Based on the analysis of supply chain collaboration and the inventory optimization for assembly manufacturing enterprises, an optimization model of multi-period dynamic decision is investigated according to the organizational behavior theory and optimization principle of cybernetics, which is based on the assembly manufacturing enterprise's target(More)
