Editorial A new hand at the helm Editors, like navigators, are a sturdy breed. There have only been four in the 63 years since the Ulster Medical Journal was founded-refounded, because we like to trace our beginnings to 1806 and the Belfast Medical Society, or perhaps more accurately to 1854 and the short lived Transactions of the Belfast Clinical and Pathological Society. But enough of history...

The eXtensible Markup Language (XML) opens the possibility to start anew, on a solid technological ground, the ambitious goal of developing a suitable technology for the creation and maintenance of a virtual, distributed, hypertextual library of formal mathematical knowledge. In particular, XML provides a central technology for storing, retrieving and processing mathematical documents, comprisi...

M ORE than one year has passed since I took over from Dr. Sankar Basu as the new Editor-in-Chief (EIC) of the IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS—II: EXPRESS BRIEFS (TCAS-II). At that time, there were some challenges that still had to be addressed to further enhance the impact and already good status of TCAS-II. After one year at the helm, I would like to report on the advancements made b...

The Holomorphic Embedding Load flow Method (HELM) employs analytic continuation of complex functions to calculate the practical (high voltage) load solution and provides promising convergence guarantees. Although HELM has been applied various types power systems, literature not thoroughly investigated three-phase distribution networks with common types/connections. In this paper, we extend ZIP ...
