Transfer Between Analogies: How Solving One Analogy Problem Helps to Solve Another

This paper deals with transfer between analogies; with what people acquire from one analogy problem-solving episode that can be re-applied to a subsequent analogy, problem-solving episode. This issue must be resolved if we are to understand the nature of expertise and the appropriate use of analogy in education. There are two main explanations of what subjects acquire from an analogy problem-so...

We investigate the complexity of an optimization problem in Boolean propositional logic related to information theory: Given a conjunctive formula over a set of relations, find a satisfying assignment with minimal Hamming distance to a given assignment that satisfies the formula (NearestOtherSolution, NOSol). We present a complete classification with respect to the relations admitted in the for...

Metabolic syndrome: yet another co-morbidity gastric bypass helps cure.

BACKGROUND The metabolic syndrome is a group of risk factors predictive of cardiovascular diseases. The rising number of obese Americans has increased the prevalence of metabolic syndrome. This study investigated the hypothesis that the incidence of metabolic syndrome is decreased after laparoscopic gastric bypass surgery. METHODS The charts of all patients who had undergone laparoscopic gast...

One thing leads to another.

In 1956, the JCI published an article by Vincent Dole on a method for titrating plasma fatty acids that uncovered the importance of fatty acids as a substrate for glucose metabolism. When asked to prepare a historical perspective on this very popular paper, I paid Dole a visit and we reminisced. His answer to my question of how he came to do this work on plasma fatty acids was: "Well, one thing...
