Highlights Availability-based engineering resilience metric is proposed. A dynamic-Bayesian-networks-based evaluation methodology is developed. A series, parallel and voting system is used for demonstrating the methodology. A nine-bus power grid system is also used for demonstrating the methodology.
Fibrous mats via electrospinning have been widely applied in tissue engineering. In this work, nanofibers were prepared via electrospinning from polymer with different content of carboxyl groups. A natural material, collagen, was then immobilized onto the nanofiber surface by N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride (EDC)/N-Hydroxysuccinimide (NHS) activation process. It was found that the immobilization degree of collagen could be facilely modulated. The obtained collagen-modified nanofibers were used for neural stem cells culture, and unmodified nanofibers were used as a control. Results indicated that the modification of collagen could enhance the attachment and viability of the cultured neural stem cells.
ADC histogram analysis may assist in assessing the WHO pathological classification and Masaoka clinical stages of thymic epithelial tumours. Advances in knowledge: 1. ADC histogram analysis could help to assess WHO pathological classification of thymic epithelial tumours. 2. ADC histogram analysis could help to evaluate Masaoka clinical stages of thymic epithelial tumours. 3. ADC might be a promising imaging biomarker for assessing and characterizing thymic epithelial tumours.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
