Demand-Adjusted Shelf Availability Parameters: A Second Look

A second look at the second law

It is commonly argued that the spectacular increase in order which has occurred on Earth does not violate the second law of thermodynamics because the Earth is an open system, and anything can happen in an open system as long as the entropy increases outside the system compensate the entropy decreases inside the system. However, if we define ‘‘X-entropy’’ to be the entropy associated with any d...

Bloomier Filters: A Second Look

A Bloom filter is a space efficient structure for storing static sets, where the space efficiency is gained at the expense of a small probability of false-positives. A Bloomier filter generalizes a Bloom filter to compactly store a function with a static support. In this article we give a simple construction of a Bloomier filter. The construction is linear in space and requires constant time to...

Double checking: a second look

RATIONALE, AIMS AND OBJECTIVES Double checking is a standard practice in many areas of health care, notwithstanding the lack of evidence supporting its efficacy. We ask in this study: 'How do front line practitioners conceptualize double checking? What are the weaknesses of double checking? What alternate views of double checking could render it a more robust process?' METHOD This is part of ...

A second look at bivalirudin.

a patient's hemostatic capacity by promoting the formation of thrombin. What happened to derail the development of bivalirudin after the initial promising findings? An angioplasty study comparing bivalirudin with UFH was conducted between 1993 and 1994 and reported in 1995. 8 Bivalirudin was found to be at least as effective as high-dose UFH in preventing ischemic complications in patients unde...
