BACKGROUND Rising rates of unplanned admissions among older people are placing unprecedented demand on health services internationally. Unplanned hospital admissions for ill-defined conditions (coded with an R prefix within Chapter XVIII of the International Classification of Diseases-10) have been targeted for admission avoidance strategies, but little is known about these admissions. The aim ...

The Historical R-tree is a spatio-temporal access method aimed at the retrieval of window queries in the past. The concept behind the method is to keep an R-tree for each timestamp in history, but allow consecutive trees to share branches when the underlying objects do not change. New branches are only created to accommodate updates from the previous timestamp. Although existing implementations...

20 where K is a coefficient which is given by gain, the size of a laser diode, internal quantum efficiency, and a confinement factor; ae,f is an internal loss; Re and R, are the reflectivities of the etched and cleaved facets, respectively. We can evaluate Re by measuring the threshold current as a function of the cavity length and by using a typical value of 0.32 for R,. The results are shown ...

From the knowledge-based view of the firm, we examined the relationship between internal R&D resources and technological alliances by data from 234 technology-based smalland medium-sized enterprises in Japan. We found: (1) the higher the internal R&D resources, the more non-equity-type alliances firms tended to pursue; (2) subjective factors such as entrepreneurial top management with overseas ...

R-trees and related structures, like R-trees and R-trees, have been used to answer queries involving topological information about objects represented by their minimum bounding rectangles (MBRs). This paper describes how the R-tree method can be used for the storage and retrieval of direction relations. Direction relations deal with order in space, as for instance, left, above, north, southeast...
