A sopranist (also, sopranista or male soprano) is a male singer who is able to sing in the vocal tessitura of a soprano usually through the use of falsetto vocal production.
 This voice type is a specific kind of countertenor.
 In rare cases an adult man may be able to sing in the soprano range using his normal or modal voice and not falsetto due to endocrinological reasons, like Radu Marian, or as a result of a larynx that has not completely developed as in the case of Michael Maniaci.
Michael Maniaci (born in 1976 May 3) is an American opera singer.
 Possessing a male soprano voice, Maniaci is noted for his claim to be able to sing into the upper soprano register without using falsetto, an otherwise common phonation for men who sing in high registers, such as countertenors. Although this was possible for castrati, because of the hormonal imbalance following castration, Maniaci claims that, for some unknown reason, his larynx did not develop and lengthen completely, causing his voice not to "break" in the usual manner.
 Maniaci claims that this physical particularity has given him the ability to sing in the soprano register without sounding like a typical countertenor or a female singer.
 There are, however, critics who claim that Maniaci actually sings in falsetto.
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.
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.
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.
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.
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).
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.
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.
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.
