Dopamine may preserve the myocardial oxygen balance better than dobutamine when administered with milrinone

Can we do better than dobutamine?

Reassessment of dobutamine, dopamine, and milrinone in the management of acute heart failure syndromes.

The appropriate role of intravenous inodilator therapy (inotropic agents with vasodilator properties) in the management of acute heart failure syndromes (AHFS) has long been a subject of controversy, mainly because of the lack of prospective, placebo-controlled trials and a lack of alternative therapies. The use of intravenous inodilator infusions, however, remains common, but highly variable. ...

When Good = Better Than Average

People report themselves to be above average on simple tasks and below average on difficult tasks. This paper builds on prior research demonstrating this effect and proposes a simpler explanation for it: that people easily conflate relative with absolute evaluation, especially on ambiguous measures of evaluation. The paper then presents a series of four studies that examine this conflation expl...

Does Median Filtering Truly Preserve Edges Better than Linear Filtering ?

Image processing researchers commonly assert that “median filtering is better than linear filtering for removing noise in the presence of edges.” Using a straightforward large-n decision-theory framework, this folk-theorem is seen to be false in general. We show that median filtering and linear filtering have similar asymptotic worst-case meansquared error (MSE) when the signal-to-noise ratio (...

Object Groups May Be Better Than Pages

I argue against trying to solve the problem of clustering objects into disk pages. Instead, I propose that objects be fetched in groups that may be specific to an application or user, and that can be computed at fetch time. I briefly describe crystals, which serve to record such groups statically. Finally, I speculate that object fetching may be particularly relevant for providing services to v...
