Background: Meningiomas are the most common intracranial tumor, graded from 1 (benign) to 3 (malignant). The aim of this study was identify clinical features associated with overall survival (OS), progression-free (PFS) and functional status for malignant meningiomas. Methods: Demographic, histopathological data grade meningioma cases were identified in databases seven sites North America Europ...

We consider weak preference orderings over a set An of n alternatives. An individual preference is of refinement ≤ n if it first partitions An into subsets of ‘tied’ alternatives, and then ranks these subsets within a linear ordering. When < n, preferences are coarse. It is shown that, if the refinement of preferences does not exceed , a super majority rule (within non-abstaining voters) with r...

This paper examines the concept of a combination rule for belief functions. It is shown that two fairly simple and apparently reasonable assumptions determine Dempster’s rule, giving a new justification for it.

— This paper shows why corruption is especially difficult to detect under China’s system of decentralized authoritarian rule, which I call a “rule of mandates.” Local officials must pursue high priority political targets but have immense discretion over which laws to implement. A relative standard for corruption consequently arises since non-implementation of laws may be mandate-serving or may ...

With the introduction of the 65-nm Cyclone® III family, Altera continues to deliver greater capabilities to designers of cost-sensitive high-volume applications. The move to the 65-nm process node provides the benefits associated with smaller process geometries: lower cost, higher performance, and greater logic capacity. However, along with these benefits, the 65-nm process brings with it new c...
