The HLA CTL is an interpreted language that is available in an HLA program source file. An interpreter executes HLA CTL statements during the compiling of an HLA source file; hence the name compile-time language. The HLA CTL includes many control statements such as #IF, #WHILE, #FOR, #PRINT, an assignment statement and so on. One can also ...
The HLA rules describe the responsibilities of federations and the federates that join. [12] Federations shall have an HLA federation object model (FOM), documented in accordance with the HLA object model template (OMT). In a federation, all representation of objects in the FOM shall be in the federates, not in the run-time infrastructure (RTI).
In simulation, run-time infrastructure (RTI) is a middleware that is required when implementing the High Level Architecture (HLA). RTI is the fundamental component of HLA. It provides a set of software services that are necessary to support federates to coordinate their operations and data exchange during a runtime execution. In other sense, it ...
HLA region of Chromosome 6. The human leukocyte antigen (HLA) system is a complex of genes on chromosome 6 in humans that encode cell-surface proteins responsible for regulation of the immune system. [1] The HLA system is also known as the human version of the major histocompatibility complex (MHC) found in many animals. [2]
The discovery of the MHC and role of histocompatibility in transplantation was a combined effort of many scientists in the 20th century. A genetic basis for transplantation rejection was proposed in a 1914 Nature paper by C.C. Little and Ernest Tyyzer, which showed that tumors transplanted between genetically identical mice grew normally, but tumors transplanted between non-identical mice were ...
The most diverse loci, namely HLA-A, HLA-B, and HLA-C, have roughly 6000, 7200, and 5800 known alleles, respectively. [39] Many HLA alleles are ancient, sometimes of closer homology to a chimpanzee MHC alleles than to some other human alleles of the same gene. MHC allelic diversity has challenged evolutionary biologists for explanation.
The HLA system is called a parallel hydraulic hybrid. In parallel systems the original vehicle drive-line remains, allowing the vehicle to operate normally when the HLA system is disengaged. When the HLA is engaged, energy is captured during deceleration and released during acceleration, in contrast to series hydraulic hybrid systems which ...
Alpha-toxin, also known as alpha-hemolysin (Hla), is the major cytotoxic agent released by bacterium Staphylococcus aureus and the first identified member of the pore forming beta-barrel toxin family. [1] This toxin consists mostly of beta sheets (68%) with only about 10% alpha helices.
