Because it is normal to have bacterial colonization, it is difficult to know which chronic wounds are infected. Despite the huge number of wounds seen in clinical practice, there are limited quality data for evaluated symptoms and signs. A review of chronic wounds in the Journal of the American Medical Association's "Rational Clinical Examination Series" quantified the importance of increased pain as an indicator of infection. The review showed that the most useful finding is an increase in the level of pain [likelihood ratio (LR) range, 11-20] makes infection much more likely, but the absence of pain (negative likelihood ratio range, 0.64-0.88) does not rule out infection (summary LR 0.64-0.88).
Why is it easy to know which chronic wounds are infected?
A: unanswerable

The first visible institution to run into trouble in the United States was the Southern California–based IndyMac, a spin-off of Countrywide Financial. Before its failure, IndyMac Bank was the largest savings and loan association in the Los Angeles market and the seventh largest mortgage originator in the United States. The failure of IndyMac Bank on July 11, 2008, was the fourth largest bank failure in United States history up until the crisis precipitated even larger failures, and the second largest failure of a regulated thrift. IndyMac Bank's parent corporation was IndyMac Bancorp until the FDIC seized IndyMac Bank. IndyMac Bancorp filed for Chapter 7 bankruptcy in July 2008.
Who was Southern California-based IndyMac a spin-off of?
A: Countrywide Financial

The Scottish philosopher David Hume (1711–1776) responded to Berkeley's criticisms of Locke, as well as other differences between early modern philosophers, and moved empiricism to a new level of skepticism. Hume argued in keeping with the empiricist view that all knowledge derives from sense experience, but he accepted that this has implications not normally acceptable to philosophers. He wrote for example, "Locke divides all arguments into demonstrative and probable. On this view, we must say that it is only probable that all men must die or that the sun will rise to-morrow, because neither of these can be demonstrated. But to conform our language more to common use, we ought to divide arguments into demonstrations, proofs, and probabilities—by ‘proofs’ meaning arguments from experience that leave no room for doubt or opposition." And,
What was Hume's nationality?
A: Scottish

The USB standard specifies relatively loose tolerances for compliant USB connectors to minimize physical incompatibilities in connectors from different vendors. To address a weakness present in some other connector standards, the USB specification also defines limits to the size of a connecting device in the area around its plug. This was done to prevent a device from blocking adjacent ports due to the size of the cable strain relief mechanism (usually molding integral with the cable outer insulation) at the connector. Compliant devices must either fit within the size restrictions or support a compliant extension cable that does.
Due to size restrictions compliant devices must what?
A:
fit within the size restrictions or support a compliant extension cable that does
