This paper investigates how consumer switching costs affect firms’ compatibility choices and social welfare in network industries. Firms face a choice between two modes of competition: make their networks incompatible and compete fiercely for market dominance, or make their networks compatible and have mild competition. By incentivizing firms to harvest their locked-in consumers rather than pri...

We consider a many-fermion model which exhibits a transition from a superconducting to a rotational phase with variation of a parameter in its Hamiltonian. The model has analytical solutions in its two limits due to the presence of dynamical symmetries. However, the symmetries are basically incompatible with one another; no simple solution exists in intermediate situations. Exact (numerical) so...

most sweet cherry (prunus avium l.) cultivars are self-incompatible and have problems of ‎fertilization and fruit set. to produce commercial crops they need compatible and suitable ‎pollinizers. the compatibility of “zarde daneshkadeh”, “protiva”, “sorati lavasan”, “haj-yosefy” ‎and “meshkin shahr” cultivars with “shoa-o-saltaneh” as seed parent studied in a randomized ‎complete block design (r...

background: the study was designed to assess the role of preoperative neutrophil, lymphocyte, and neutrophil?lymphocyte ratio (nlr) in predicting survival outcomes of abo?incompatible liver transplantation (lt). materials and methods: we retrospectively collected the demographic and clinical  characteristics of 71 patients with end?stage liver cirrhosis following abo?incompatible lt in this stu...

We consider the problem of training a statistical parser in the situation when there are multiple treebanks available, and these treebanks are annotated according to different linguistic conventions. To address this problem, we present two simple adaptation methods: the first method is based on the idea of using a shared feature representation when parsing multiple treebanks, and the second met...

Quantum theory describes events on the most fundamental level currently available. The synthesis of information from mutually incompatible quantum measurements plays the key role in testing the structure of the theory. The purpose of this Letter is to show a unique relationship between quantum theory and the mathematical statistics used to obtain optimal information from incompatible observatio...
