Chinese multinational enterprises' firm-specific advantages and a critic on the international business theory [PDF]

open access: yes, 2013
We argue that the extant literature tends to view that EMNEs do not have FSAs and in particular, innovation-based ownership advantages. This, however, is not a fact but a myth that deserves detailed examination.

Recursive Online Enumeration of All Minimal Unsatisfiable Subsets

open access: yes, 2018
In various areas of computer science, we deal with a set of constraints to be satisfied. If the constraints cannot be satisfied simultaneously, it is desirable to identify the core problems among them. Such cores are called minimal unsatisfiable subsets (

A Nanoparticle‐Integrated Complete Manufacturing Pipeline of Chemically Engineered Exosomes

open access: yesAdvanced Science, EarlyView.
We report a novel manufacture technology of chemically engineered exosomes. The four steps of manufacturing, i.e., biogenesis, loading, isolation, and storage, are integrated by the use of a nanoparticle. The manufacture technology incorporates three innovative components, i.e., a new nano‐bio effect, a new composite nanoparticle, and a new isolation ...
