The purpose of this study was to examine the types of self-reported search strategies and cues that older adults use to find their way in a virtual maze. DESIGN AND METHODS Healthy, independently living older adults (n = 129) aged 55-96 were tested in a...

he future of healthcare delivery systems will depend on heir ability to provide the best care at the least cost. In he clinical laboratory, this translates to ensuring that lecreased test use means appropriate use.

Testing is the process of stimulating a system with inputs in order to reveal hidden parts of the system state. We consider a variant of the testing problem that was put forward in the model-based diagnosis literature, and consists of finding input patterns that definitely discriminate between different constraint-based system models. We show that this problem can be framed as a game played bet...

Immunoglobulin sequences from an individual Xenopus laevis froglet were analyzed for combinatorial and junctional diversity. In an animal with about 10(6) B lymphocytes, at least 26 out of the 56 VH1 genes available in a diploid genome were expressed, as were all JH segments. Junctional diversity was similar to that observed in Xenopus tadpole sequences, that is, little or no N diversification ...

The purpose of this paper is to show that for a dense G set of three smooth convex bodies with nowhere vanishing curvature in the C topology k the open billiard obtained from these convex bod ies determines a potential the one that de nes the natural escape measure of this billiard which is non lattice This result generalizes one of the results obtained in a previous work of A Lopes and R Marka...

Scholars have been investigating the quick emergence of digital platforms, essentially through the lens of digital native firms. If there is limited occurrence of platforms launched by incumbent firms such as Daimler (Car2Go, Moovel) or Johnson Controls (Panopix), the economics of their strategic responses through platforms by incumbents merit attention. This paper provides the first largescale...
