The A-class torpedo boats were a class of German single-funnelled torpedo boat/light destroyer designed by the Reichsmarineamt for operations off the coast of occupied Flanders in the First World War. The "A" designation was to avoid confusion with older classes and designs. They were classed officially as "coastal torpedo boats" to differentiate from larger, ocean-going torpedo boats.
Although all RAID implementations differ from the specification to some extent, some companies and open-source projects have developed non-standard RAID implementations that differ substantially from the standard. Additionally, there are non-RAID drive architectures, providing configurations of multiple hard drives not referred to by RAID acronyms.

Human leukocyte antigens (HLA) began as a list of antigens identified as a result of transplant rejection. The antigens were initially identified by categorizing and performing massive statistical analyses on interactions between blood types. This process is based upon the principle of serotypes. HLA are not typical antigens, like those found on surface of infectious agents. HLAs are alloantigens, they vary from individual to individual as a result of genetic differences. An organ called the thymus is responsible for ensuring that any T-cells that attack self proteins are not allowed to live. In essence, every individual's immune system is tuned to the specific set of HLA and self proteins produced by that individual; where this goes awry is when tissues are transferred to another person. Since individuals almost always have different "banks" of HLAs, the immune system of the recipient recognizes the transplanted tissue as non-self and destroys the foreign tissue, leading to transplant rejection. It was through the realization of this that HLAs were discovered.
The Circé-class submarines consisted of a pair of submarines built for the French Navy during the first decade of the 20th century. One boat was sunk in a collision before the First World War and the other was torpedoed and sunk by a German submarine in the last year of the war.
