Hexagonal pattern formation in the pigment structure of electrophoretic image displays (EPIDs) is measured in samples with a high concentration of free charge. In this article we will explain which phenomenon is at the origin of the pattern formation.

We study the solution concepts of partial cooperative Cournot-Nash equilibria and partial cooperative Stackelberg equilibria. The partial cooperative Cournot-Nash equilibrium is axiomatically characterized by using notions of rationality, consistency and converse consistency with regard to reduced games. We also establish sufficient conditions for which partial cooperative Cournot-Nash equilibr...

For the connections model of strategic network formation, with two-way flow of information and without information decay, specific parameter configurations are given for which Nash networks do not exist. Moreover, existence and the scope of Nash network architectures are briefly discussed. JEL Classification Numbers C72 · D85

mandibular defects may result from many conditions such as trauma, inflammatory diseases and tumors. there are rare cases reported in the literature that have demonstrated spontaneous bone regeneration after resection of the mandible. several factors such as age, preservation of the periosteum and genetics seem to influence spontaneous bone regeneration capacity in individuals. evaluation of th...

the dependence on ionic strength of protonation of l-aspartic acid and its complexation withdioxouranium(vi) is reported in sodium perchlorate solution as a background salt. the measurementshave been performed at 25 ± 0.1 °c and various ionic strengths in the range 0.1 to 1.0 mol dm-3, using acombination of potentiometric and spectrophotometric techniques. the overall analysis of the present an...
