An uncovered bargaining solution is a bargaining solution for which there exists a complete and strict relation (tournament) such that, for each feasible set, the bargaining solution set coincides with the uncovered set of the tournament. We provide a characterization of a class of uncovered bargaining solutions. J.E.L. codes: C72, D44.

Composition-driven transition to the crystalline state is characteristic of amorphous metal alloys and widely observed in thin film. However, zone (compositional range between single-phase films) remains unexplored. Here, we demonstrate that this offers an excellent scenario for fabrication hybrid crystalline-amorphous architectures. The peculiar morphology these nano(micro)-structured films pr...

Over half of patients diagnosed with esophageal cancer are unsuitable for curative resection. A significant proportion of these patients will subsequently require palliative stenting to alleviate dysphagia. There is growing consensus in the literature that the deployment of a Self-Expanding Metal Stent is the optimum stenting strategy; however, it remains unclear whether covered or uncovered me...

Migraine is a serious health problem which impair quality of life. It is the second most common primary headache that affects approximately more than %10 people in general population. Migraine pathophysiology is still unclear. Increasing results of studies suggest to migraine pathophysiology is related with primary neuronal mechanisms. Migraine pain starts in which region of brain and what brai...

By employing the spin-boson model in a dense limit of environmental modes, quantum entanglement and correlation sub-Ohmic Ohmic baths for dissipative phase transitions are numerically investigated based on variational principle. With several measures borrowed from information theory, three different types singularities found first-order, second-order, Kosterlitz-Thouless transitions, respective...

We investigate the characteristics of temporal phase locking states observed in the route to phase synchronization. It is found that before phase synchronization there is a periodic phase synchronization state characterized by periodic appearance of temporal phase-locking state and that the state leads to local negativeness in one of the vanishing Lyapunov exponents. By taking a statistical mea...

Comparative News Summarization aims to highlight the commonalities and differences between two comparable news topics. In this study, we propose a novel approach to generating comparative news summaries. We formulate the task as an optimization problem of selecting proper sentences to maximize the comparativeness within the summary and the representativeness to both news topics. We consider sem...
