Question: What type of collection does Etarcomol and Medb have in common?

Context paragraphs:
Marinko Sudac Collection: The Marinko Sudac Collection, based in Zagreb, Croatia, has been created with a clear collecting strategy based on the region of Central and Eastern Europe, additionally spanning from the Baltic area to the Black Sea.  The guiding principle of the Collection is systematic exploration, researching, and promotion of the Avant-Garde practices which have been marginalized, forbidden, and at times completely negated due to the historical, social and political circumstances.  In this context, the Marinko Sudac Collection gives the most complete and comprehensive overview on the art of this region.  The Collection starts at 1909, and it show the continuity from the first Avant-Gardes, through Neo-Avant-Garde and New Artistic Practices, ending with the fall of the Berlin Wall.  The global uniqueness of the Marinko Sudac Collection is also seen in the kind of media it contains.  It contains not only traditional artworks, such as paintings, sculptures, and photographs, but it gives equal importance to documentary and archival material.  Great importance is put on these almost forgotten media, which enable research of specific phenomena, artists and the socio-political situation which affected this type of art.  The Collection contains a great number of museological units, and it treats the documentary and archival material on the same level as traditional artworks.  By examining the units contained in the Marinko Sudac Collection, one can read not only the art scene or the art production of a certain artist, but the full status of the society, the socio-political atmosphere of the region in which this art was created in.

Cis AB: Cis AB is a rare mutation in the ABO gene which complicates the basic inheritance pattern and blood-transfusion compatibility matching for ABO blood typing.  There are different DNA mutations of either type A or Type B alleles that change several amino acids in enzyme transferase A or B, homologous enzymes differing in only four of 354 amino acids (R176G, G235S, L266M, and G268A).  A single change in ABO gene DNA could reverse type B to type A and then, a new hybrid enzyme will produce both weak B and A2 (in serum test, A2B and A2B3)).  The most common mutation is an A105 allele variation in exon 7 nucleotide position G803C changing Glycine (type A) to Alanine (type B).  There are another 8 alleles reported in BGMUT, the most discovered reciently in China and Taiwan.  In the cis-AB genotype, both antigens are expressed, like in a standard (trans) AB genotype.  In a traditional AB phenotype, A and B antigenes are inherited separately from the father and mother while a cis-AB allele comes from one parent only.  In a serum test, cis-AB tests almost the same as a traditional AB, but people with this rare type have problems with blood transfusions.  Some of them need components like washed red blood cells or autotransfusion of serum and blood.

Tracing garbage collection: In computer programming, tracing garbage collection is a form of automatic memory management that consists of determining which objects should be deallocated ("garbage collected") by tracing which objects are "reachable" by a chain of references from certain "root" objects, and considering the rest as "garbage" and collecting them.  Tracing garbage collection is the most common type of garbage collection – so much so that "garbage collection" often refers to tracing garbage collection, rather than other methods such as reference counting – and there are a large number of algorithms used in implementation.

Collection (abstract data type): In computer science, a collection or container is a grouping of some variable number of data items (possibly zero) that have some shared significance to the problem being solved and need to be operated upon together in some controlled fashion.  Generally, the data items will be of the same type or, in languages supporting inheritance, derived from some common ancestor type.  A collection is a concept applicable to abstract data types, and does not prescribe a specific implementation as a concrete data structure, though often there is a conventional choice (see Container for type theory discussion).

Garbage truck: Garbage truck or dustcart refers to a truck specially designed to collect municipal solid waste and haul the collected waste to a solid waste treatment facility such as a landfill.  Other common names for this type of truck include trash truck in the United States, and rubbish truck, junk truck, dumpster, bin wagon, dustbin lorry, bin lorry or bin van elsewhere.  Technical names include waste collection vehicle and refuse collection vehicle.  These trucks are a common sight in most urban areas.

Uterine cancer: 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.

Skin cancer in horses: Skin cancer, or neoplasia, is the most common type of cancer diagnosed in horses, accounting for 45 to 80% of all cancers diagnosed.  Sarcoids are the most common type of skin neoplasm and are the most common type of cancer overall in horses.  Squamous-cell carcinoma is the second-most prevalent skin cancer, followed by melanoma.  Squamous-cell carcinoma and melanoma usually occur in horses greater than 9-years-old, while sarcoids commonly affect horses 3 to 6 years old.  Surgical biopsy is the method of choice for diagnosis of most equine skin cancers, but is contraindicated for cases of sarcoids.  Prognosis and treatment effectiveness varies based on type of cancer, degree of local tissue destruction, evidence of spread to other organs (metastasis) and location of the tumor.  Not all cancers metastasize and some can be cured or mitigated by surgical removal of the cancerous tissue or through use of chemotherapeutic drugs.

Etarcomol: Etarconol is a character from the Ulster Cycle in Irish folklore.  He is the son of Eda and Léthrenn and a foster-son of Ailill and Medb.  He was the first champion to face Cúchulainn in single combat.  He was killed as Cúchulainn struck down through his crown and split him "to the navel".

Container (type theory): In type theory, containers are abstractions which permit various "collection types", such as lists and trees, to be represented in a uniform way.  A (unary) container is defined by a type of "shapes" S and a type family of "positions" P, indexed by S.  The "extension" of a container is a family of dependent pairs consisting of a shape (of type S) and a function from positions of that shape to the element type.  Containers can be seen as canonical forms for collection types.

Medb: Medb (pronounced ] )—later spelled Meadhbh (] ) and Méabh (] )—is queen of Connacht in the Ulster Cycle of Irish mythology.  Her husband in the core stories of the cycle is Ailill mac Máta, although she had several husbands before him who were also kings of Connacht.  She rules from Cruachan (now Rathcroghan, County Roscommon).  She is the enemy (and former wife) of Conchobar mac Nessa, king of Ulster, and is best known for starting the "Táin Bó Cúailnge" ("The Cattle Raid of Cooley") to steal Ulster's prize stud bull.  Medb is strong-willed, ambitious, cunning and promiscuous, and is an archetypal warrior queen.  She is believed to be a manifestation of the sovereignty goddess.  Medb of Connacht is probably identical with Medb Lethderg, the sovereignty goddess of Tara, and may also be linked with the Morrígan.
