Spending on Medicare has grown 2.4 percentage points faster than GDP over the last thirty years. If growth at these rates were to continue, Medicare alone would account for 31% of GDP by 2082, and healthcare expenditures in total would reach 99% of GDP. In order to generate more reasonable projections, researchers and policy analysts in the government have explored a number of different approac...

changes in credit risk may arise when either the value or the risk of corporate assets changes. changes in the equity value associated with the changes in the asset value and changes in asset risk can be characterized into potentially countervailing direct and indirect effects. the indirect effect of risk on equity value is a function of factors that affect the debt value of including leverage,...

QuickCheck-style property-based random testing [4] requires efficient generators for well-distributed random data satisfying complex logical predicates. Writing such generators by hand can be difficult and error prone. We propose a domain-specific language, Luck, in which generators are expressed by decorating predicates with lightweight annotations controlling both the distribution of generate...

In these days when everyone seems interested in "art therapy" this book is very timely and it is of special interest to our readers that the author has had considerable experience with psychiatric patients. He has dedicated it to Dr.

cientists have discovered a new function for amyloid precursor protein (APP), a protein linked to Alzheimer’s disease. The finding may reveal how APP gets mixed up with the enzymes that make it go bad. APP has an evil reputation. The and secretases transform it into amyloidpeptide, a component of the plaques that riddle the brain in Alzheimer’s disease. Previous work by Larry Goldstein (Univesi...

We report two studies of facial self-perception using individually tailored, standardized facial photographs of a group of volunteers and their partners. A computerized morphing procedure was used to merge each target face with an unknown control face. In the first set of experiments, a discrimination task revealed a delayed response time for the more extensively morphed self-face stimuli. In a...

The typical pattern-recognition program is either elaborately preprogrammed to process specific arrays of input patterns, or else it has been designed as a tabula rasa, with certain abilities to adjust its values, or "learn." The first type often cannot identify large classes of patterns that appear only trivially different to the human eye, but that would completely escape the machine's logic ...
