For analyzing prescription datasets, usually one wishes to identify drugs by classes, rather than by U.S. FDANational Drug Codes. We demonstrate how to utilize the NLM RxNorm online API to map NDCs to WHOAnatomical-Therapeutic-Chemical classes, and present statistics and caveats of mapping 71,309 NDCs found inMedicare Part D claims from 2006 to 2013 and 134,580 NDCs found in a c...

Virtual impedances are often used in droop-controlled paralleled-voltage-sourced inverters (VSIs) to achieve proper power sharing. However, different and unknown output of VSIs will affect the decoupling sharing performances. To solve this problem, article proposes a novel controller for by using disturbance observer (DOB). The DOB is adopted observe currents without any extra current sensors. ...

A widely embraced approach to mitigate the dynamic degradation in low-inertia power systems is mimic generation response using grid-connected inverters restore stiffness of grid. In this article, we seek challenge and advocate for a principled design based on systematic analysis performance trade-offs inverter-based frequency control. With aim, perform qualitative quantitative study comparing e...

Non Interference 8] has been proposed for modelling and analysing information ow in systems. In 4,7] we have indeed shown that the Non Interference property called NDC can be applied also in the area of network security, for the analysis of typical cryptographic protocol properties (e.g., authentication, non-repudiation). In this paper we extend the results of 4,7] by showing that NDC can be al...

A metal-organic framework Zn(NDC)(4,4'-Bpe)(0.5).xG [NDC = 2,6-naphthalenedicarboxylate; 4,4'-Bpe = 4,4'-trans-bis(4-pyridyl)ethylene; G = guest molecules] has been synthesized, structurally characterized, and rationalized to be a two-interpenetrated elongated primitive cubic net. Powder X-ray diffraction and adsorption studies reveal the dynamic feature of the framework, which can take up hydr...

This paper proposes a novel control scheme for provision of frequency support among asynchronous AC areas through HVDC grids. It is based on local controllers, each acting on a voltage source converter, using local measurements only, and supporting frequency of the adjacent AC area after a significant disturbance. The new discrete control is combined with the existing DC voltage droop technique...
