Type I hypersensitivity (or immediate hypersensitivity) is an allergic reaction provoked by reexposure to a specific type of antigen referred to as an allergen.
 Type I is not to be confused with type II, type III, or type IV hypersensitivities, nor is it to be confused with Type I Diabetes or Type I of any other disease or reaction.
A star war was a decisive conflict between rival polities of the Maya civilization during the first millennium AD.
 The term comes from a specific type of glyph used in the Maya script, which depicts a star showering the earth with liquid droplets, or a star over a shell.
 It represents a verb but its phonemic value and specific meaning have not yet been deciphered.
 The name "star war" was coined by the epigrapher Linda Schele to refer to the glyph, and by extension to the type of conflict that it indicates.
Anti-MAG Peripheral Neuropathy is a specific type of peripheral neuropathy in which the person’s own immune system attacks cells that are specific in maintaining a healthy nervous system.
 As these cells are destroyed by antibodies, the nerve cells in the surrounding region begin to lose function and create many problems in both sensory and motor function.
 Specifically, antibodies against myelin-associated glycoprotein (MAG) damage Schwann cells.
 While the disorder occurs in only 10% of those afflicted with peripheral neuropathy, people afflicted have symptoms such as muscle weakness, sensory problems, and other motor deficits usually starting in the form of a tremor of the hands or trouble walking.
 There are, however, multiple treatments that range from simple exercises in order to build strength to targeted drug treatments that have been shown to improve function in people with this type of peripheral neuropathy.
Balderdash is a board game of bluffing and trivia created by Laura Robinson and Paul Toyne of Toronto, Ontario, Canada.
 The game was first released in 1984 under Canada Games.
 It was later picked up by a U.S company, The Games Gang, and eventually became the property of Hasbro and finally Mattel.
 The game is based on a classic parlor game called Fictionary.
 The game has sold over 15 million copies worldwide to date.
 It is aimed at fans of word games, such as "Scrabble".
In programming languages, ad hoc polymorphism is a kind of polymorphism in which polymorphic functions can be applied to arguments of different types, because a polymorphic function can denote a number of distinct and potentially heterogeneous implementations depending on the type of argument(s) to which it is applied.
 It is also known as function overloading or operator overloading.
 The term ad hoc in this context is not intended to be pejorative; it refers simply to the fact that this type of polymorphism is not a fundamental feature of the type system.
 This is in contrast to parametric polymorphism, in which polymorphic functions are written without mention of any specific type, and can thus apply a single abstract implementation to any number of types in a transparent way.
 This classification was introduced by Christopher Strachey in 1967.
In solid-state physics, heavy fermion materials are a specific type of intermetallic compound, containing elements with 4f or 5f electrons in unfilled electron bands.
 Electrons are one type of fermion, and when they are found in such materials, they are sometimes referred to as heavy electrons.
 Heavy fermion materials have a low-temperature specific heat whose linear term is up to 1000 times larger than the value expected from the free-electron theory.
 The properties of the heavy fermion compounds often derive from the partly filled f-orbitals of rare-earth or actinide ions, which behave like localized magnetic moments.
 The name "heavy fermion" comes from the fact that the fermion behaves as if it has an effective mass greater than its rest mass.
 In the case of electrons, below a characteristic temperature (typically 10 K), the conduction electrons in these metallic compounds behave as if they had an effective mass up to 1000 times the free-electron mass.
 This large effective mass is also reflected in a large contribution to the resistivity from electron-electron scattering via the Kadowaki Woods ratio.
 Heavy fermion behavior has been found in a broad variety of states including metallic, superconducting, insulating and magnetic states.
 Characteristic examples are CeCu, CeAl, CeCuSi, YbAl, UBe and UPt.
The following article lists the available programs for fixing a specific type of archive that has been corrupted (for example by downloading via the internet).
 Although some file archivers also have the function to repair certain types of archives, it is not always clear which type of archive can be repaired with it.
 This list intents to clear this up, and also mention dedicated repair programs (that may not be able to decompress or compress the file type they can repair).
Titan is a fantasy board game for two to six players, designed by Jason B. McAllister and David A. Trampier.
 It was first published in 1980 by Gorgonstar, a small company created by the designers.
 Soon afterward, the rights were licensed to Avalon Hill, which made several minor revisions and published the game for many years.
 "Titan" went out of print in 1998, when Avalon Hill was sold and ceased operations.
 A new edition of "Titan", with artwork by Kurt Miller and Mike Doyle and produced by Canadian publisher Valley Games became available in late 2008.
 The Valley Games edition was adapted to the Apple iPad and released on December 21, 2011.
Neutrophil swarming is a specific type of neutrophil migration behaviour characterised by a high coordination between neutrophils, clustering of neutrophils to the inflammation site and signalling to other neutrophils further away.
 This specific type of migration rely on the production and secretion of LTB4 and on the use of integrins for neutrophil to stop at the cluster site.
Uterine cancer or womb cancer is any type of cancer that emerges from the tissue of the uterus.
 It can refer to several types of cancer, with cervical cancer (arising from the lower portion of the uterus) being the most common type worldwide and the second most common cancer in women in developing countries.
 Endometrial cancer (or cancer of the inner lining of the uterus) is the second most common type, and fourth most common cancer in women from developed countries.
 Risk factors depend on specific type, but obesity, older age, and human papillomavirus infection add the greatest risk of developing uterine cancer.
 Early on, there may be no symptoms, but irregular vaginal bleeding, pelvic pain or fullness may develop.
 If caught early, most types of uterine cancer can be cured using surgical or medical methods.
 When the cancer has extended beyond the uterine tissue, more advanced treatments including combinations of chemotherapy, radiation therapy, or surgery may be required.

Question: Titan and Balderdash, are which specific type of entertainment?
Answer: board game
