The Baillon-Haddad Theorem Revisited

In 1977, Baillon and Haddad proved that if the gradient of a convex and continuously differentiable function is nonexpansive, then it is actually firmly nonexpansive. This result, which has become known as the Baillon-Haddad theorem, has found many applications in optimization and numerical functional analysis. In this note, we propose short alternative proofs of this result and strengthen its ...

The brain is not dead when the cortex is dead.

To the Editor: In a recent issue of Critical Care Medicine, with interest we read the article by Dhanani et al (1), concerning vital signs after circulatory arrest following withdrawal of lifesustaining therapy. The article has timely given the persistent controversy regarding criteria of death in circulatory death organ donors. How many minutes after circulatory arrest can we consider the pati...

Is N-Best Dead?

We developed a faster search algorithm that avoids the use of the N-Best paradigm until after more powerful knowledge sources have been used. We found, however, that there was little or no decrease in word errors. We then showed that the use of the N-Best paradigm is still essential for the use of still more powerful knowledge sources, and for several other purposes that are outlined in the pap...

Is the EMR dead?

Converting to an electronic medical record (EMR) has been the health care system's collective goal for decades. Hundreds of EMRs have been developed during the last 30 years, but the likelihood of a patient having a largely electronic medical record in the near future remains slim. Adoption has been slow, and the physician time required to enter data is still daunting. And related technologies,...
