An exchange economy is modeled as a strategic market game with all pairwise markets available. Existence of noncooperative equilibria is proved. It is shown that if resources are distributed in a skewed manner, in equilibrium prices may not satisfy the no arbitrage condition. One round of trade even with all goods serving as money is not sufficient to provide enough liquidity for efftcient trad...

NATO Research Task Group IST-021/RTG-007 interpreted visualisation as a human activity supported by technology. Visualisation is therefore a means by which humans make sense of complex data. The RTG considered visualisation technologies, including display devices and techniques in relation to how they help humans to perform their tasks effectively. The RTG emphasized the human use of the comput...

This article is a presentation of a clinical methodology aimed at minimizing binding in fixed orthodontic appliances. The dynforce archwire is explained. The dynforce archwire has a full size anterior segment (e.g. .021×.025) and undersized posterior segments with rectangular cross-section (e.g. .018×.025 or .018×.022), and is used in the orthodontic phase of space closure with or without TAD m...

In this paper we describe and compare two different methods to reduce the cardinality of the set of candidates nodules, characterized by an high sensitivity ratio, and extracted from PA chest radiographs by a fully automatized method. The methods are a rule based system and a feed-forward neural network trained by back-propagation. Both the systems allow to recognize almost the 021 % of false p...

The asymmetric unit of the title compound, C11H10N4O3, contains two independent mol-ecules in which the benzene rings make dihedral angles of 38.3 (2) and 87.1 (2)° with respect to the triazole rings. In the crystal, the mol-ecules are linked by C-H⋯O hydrogen bonds, forming chains along [021]. Further, weak C-O⋯π [3.865 (5) Å, 83.8 (3)°] and N-O⋯π [3.275 (5) and 3.240 (6) Å, 141.8 (4) and 102....

Recent evidence has shown possible scaling and self-similarity in high frequency financial time series. This paper demonstrates that many of these graphical scaling results could have been generated by a simple stochastic volatility model. This casts doubt on the power of these tests to discern between true scaling and simple highly dependent stochastic processes. JEL Classification: C32, G12 ∗...
