TANS Perú
TANS Perú, an acronym for Transportes Aéreos Nacionales de Selva, was a Peruvian airline based in Lima. The airline was headquartered at the Miraflores District, Lima, Miraflores District in the capital city of the country. Completely state-owned, the Air carrier, carrier operated scheduled domestic passenger and cargo services from its main base at Jorge Chávez International Airport. History ''TANS'' (also known as ''Grupo Aéreo de Transporte 42'' was established in 1963 as an arm of the Peruvian Air Force, based at the remote city of Iquitos, inaccessible by road, and tasked with providing scheduled airline flights, together with fulfilling search and rescue and medevac needs. In 1988, its fleet consisted of a mixture of Pilatus PC-6 Porters and de Havilland Canada DHC-6 Twin Otters, mainly operating as floatplanes. Although its missions were mainly civilian, it remained part of the Air Force until 1999, being granted civil certification in November 1999. At , the fleet incl ...

Queen Alexandra's Royal Army Nursing Corps
Queen Alexandra's Royal Army Nursing Corps (QARANC; known as ''the QAs'') is the nursing branch of the British Army Medical Services. History Although an "official" nursing service was not established until 1881, the corps traces its heritage to Florence Nightingale, who was instrumental in lobbying for the support of female military nurses. The Army Nursing Service, which had been established in 1881, and which from 1889 provided Sisters for all Army hospitals with at least 100 beds, had only a small number of nurses in its employ. In 1897, in an effort to have nurses available if needed for war, the service was supplemented by Princess Christian's Army Nursing Service Reserve (PCANSR). Nurses registered for the service and by the beginning of the First Boer War the reserve had around 100 members, but swelled its membership to over 1400 during the conflict. PCANSR eventually became the Queen Alexandra's Imperial Military Nursing Service. On 27 March 1902, Queen Alexandra's Imp ...

Typhoid Army Nursing Service
Typhoid fever, also known as typhoid, is a disease caused by ''Salmonella'' serotype Typhi bacteria. Symptoms vary from mild to severe, and usually begin six to 30 days after exposure. Often there is a gradual onset of a high fever over several days. This is commonly accompanied by weakness, abdominal pain, constipation, headaches, and mild vomiting. Some people develop a skin rash with rose colored spots. In severe cases, people may experience confusion. Without treatment, symptoms may last weeks or months. Diarrhea may be severe, but is uncommon. Other people may carry the bacterium without being affected, but they are still able to spread the disease. Typhoid fever is a type of enteric fever, along with paratyphoid fever. ''S. enterica'' Typhi is believed to infect and replicate only within humans. Typhoid is caused by the bacterium ''Salmonella enterica'' subsp. ''enterica'' serovar Typhi growing in the intestines, peyers patches, mesenteric lymph nodes, spleen, liver, ...

Asymmetric Numeral Systems
Asymmetric numeral systems (ANS)J. Duda, K. Tahboub, N. J. Gadil, E. J. Delp''The use of asymmetric numeral systems as an accurate replacement for Huffman coding'' Picture Coding Symposium, 2015.J. Duda''Asymmetric numeral systems: entropy coding combining speed of Huffman coding with compression rate of arithmetic coding'' arXiv:1311.2540, 2013. is a family of entropy encoding methods introduced by Jarosław (Jarek) Duda from Jagiellonian University, used in data compression since 2014 due to improved performance compared to previous methods. ANS combines the compression ratio of arithmetic coding (which uses a nearly accurate probability distribution), with a processing cost similar to that of Huffman coding. In the tabled ANS (tANS) variant, this is achieved by constructing a finite-state machine to operate on a large alphabet without using multiplication. Among others, ANS is used in the Facebook Zstandard compressor
