For the iron-based high Tc superconductor LaFeAsO1−xFx, we construct a minimal model, where all of the five Fe d bands turn out to be involved. We then investigate the origin of superconductivity with a five-band random-phase approximation by solving the Eliashberg equation. We conclude that the spin fluctuation modes arising from the nesting between the disconnected Fermi pockets realise, basi...

We are interested in exploring ways in which unconventional modes of computation may provide new directions for future developments in Computer Music. Research into Unconventional Computing (Calude et al. 1998) is aimed at computational paradigms other than the standard von Neumann architecture, which have prevailed in computing since the 1940s. This paper presents an investigation into the fea...

Extended Abstract: This paper has several objectives. First, it separates randomness from lawlessness and shows why even genuine randomness does not imply lawlessness. Second, it separates the question “why should I call a phenomenon random?” (and answers it in part one ) from the patent question “What is a random sequence?” for which the answer lies in Kolmogorov complexity ( which is explaine...

Purpose – The purpose of this paper is to introduce and conceptualize the topic of Model-based management (MBM) in organizations. Design/methodology/approach – The relevance of different types of models for management is elaborated, and a research agenda for this new topic is proposed. Findings – An analysis of the concept, role and function of models in the context of management and organizati...

This is the third in a series of 5 articles providing a contemporary overview and introduction to unconventional dentistry (UD) and its correlation to unconventional medicine (UM). UD presents issues of dental quackery, fraud and malpractice, and it also engenders professional concerns about public protection and professional risks. Case reports illustrate numerous issues. The reader is encoura...

Science is an "endless frontier," and opportunities for transformative discovery abound. The young scientist will profit by paying mind to two forms of balance: the contrast between depth and breadth in training, and the contrast between hypothesis-driven research and random inquiry into the unknown.

As power systems integrate more intermittent renewable generation, and as extreme weather events become more frequent with climate change, power systems are likely to require increasing amounts of spinning reserves in order to maintain reliable operation. While traditionally spinning reserves have been supplied by generators, demand-side resources can also provide reserves by increasing or decr...

Discussion of reserves’ adequacy has renewed after financial crises in Asia and Russia. It became evident that large international reserves made countries less prone to crisis. Special attention was paid to the ratio of a country’s external short-term debt to reserves as a very successful marker of potential external vulnerability that generally outperforms other reserves’ adequacy criteria. Th...

Unit commitment optimization for the scheduling of units and effective load sharing among thermal units is extensively used in electrical power system planning. The target of unit commitment optimization will be economical when the criteria is to test the best combination of thermal units to serve the load with the optimium load sharing among units satisfying various constraints like load deman...
