1 A hair of the dog, which means another alcoholic drink, isn't a good idea. The hangover will just be twice as bad the next day.  The effects can actually last 48 hours so it's best to have a couple of days off drinking after a heavy session to let your body recover.
The High Level Architecture (HLA) provides the specification of a common technical architecture for use across all classes of simulations in the US Department of Defense. It provides the structural basis for simulation interoperability. The baseline definition of the HLA includes (1) the HLA Rules, (2) the HLA Interface Specification, and (3) the HLA Object Model Template. This paper describes the motivations and processes used to develop the High Level Architecture and provides a technical description of key elements of the architecture and supporting software.
An HLA disease association is defined as a statistically increased frequency of the HLA haplotype in individuals with the disease compared to the frequency in individuals without the disease. This is expressed as a relative risk. For example, HLA-B27 appears in 80-90% of patients with ankylosing spondylitis.
