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.
The human leukocyte antigen system or complex is a gene complex encoding the major histocompatibility complex proteins in humans. These cell-surface proteins are responsible for the regulation of the immune system in humans. The HLA gene complex resides on a 3 Mbp stretch within chromosome 6p21. HLA genes are highly polymorphic, which means that they have many different alleles, allowing them to fine-tune the adaptive immune system. The proteins encoded by certain genes are also known as antigen
