The use of abbreviations and acronyms in medical records and reports may lead to errors in patient care as they may be misunderstood or misinterpreted. When acronyms and abbreviations are used, they should always be defined within the records, report etc. in which they appear, thus: “Mr. Jones has suffered a cerebrovascular accident (CVA). .
COMMONLY USED ACRONYMS If you interact with Medicare, you probably encounter acronyms on a regular basis. It can be difficult sometimes to keep track of them all. This resource is a list of Medicare-related acronyms. While the list is not all-inclusive, it contains those acronyms you may encounter on a regular basis in the course of your

to the entire field of artificial intelligence. Humans, it seems, know things and do reasoning. Knowledge and reasoning are also important for artificial agents because they enable successful behaviors that would be very hard to achieve otherwise. We have seen that knowledge of action outcomes enables problem-solving agents to perform well in complex environments. A reflex agents could onl
