Context paragraphs:
State Savings Bank (Logan, Iowa): State Savings Bank, also known as Harrison Mutual Insurance Association, is a historic building located in Logan, Iowa, United States.  Founded in 1888, the bank built this building in 1902.  It is a two-story brick structure with terra cotta ornamentation.  Its wrap-around design is made possible for this mid-block building by its alley location.  State Savings Bank was one of four banks that operated in the town over its history.  It failed in 1923.  After the building sat empty for five years Harrison Mutual Insurance Association purchased the building.  It was listed on the National Register of Historic Places in 1985.

Neolloydia: Neolloydia is a genus of cacti.  The genus is uniquely found in the dry scrub areas of southern Texas (Big Bend) and the Chihuahua Desert of Northeast Mexico.

PlWordNet: plWordNet – a lexico-semantic database of Polish language.  It includes sets of synonymous lexical units (synsets) followed by short definitions.  plWordNet serves as a thesaurus-dictionary where concepts (synsets) and individual word meanings (lexical units) are defined by their location in the network of mutual relations, reflecting the lexico-semantic system of Polish language.  plWordNet is also used as one of the basic resources for the construction of natural language processing tools for Polish.

Sangsaeng: Sangsaeng (相生) means mutual life-giving, and is one of the key philosophical principles of Jeungism, a spiritual movement from Korea dedicated to the well-being of all people.  In English terms, "win-win" maybe the correct translation.  Sang(相) means "mutual" or "together" and Saeng(生) means "live" or "survive".  Because of its literal meaning, mutual life-giving or win-win, this term is used by Korean politicians very often.

University of Pristina (1969–99): The University of Pristina was founded in the Socialist Autonomous Province of Kosovo, Socialist Republic of Serbia, Yugoslavia, in the city of Pristina, for the academic year 1969–1970 and functioned until 1999.  However, owing to political upheaval, war, successive mutual expulsions of faculty of one ethnicity or the other, and resultant pervasive ethnic-based polarisation, there came to be two disjoint institutions using the same name, albeit idiosyncratically to reflect ethnic identity.  Albanian-language activity continues at the original location (Albanian: "Universiteti i Prishtinës" ), whilst the Serbian-named "Univerzitet u Prištini" has relocated to Kosovska Mitrovica where it maintains its place within the Serbian education system.

Mutual Live: In the fall of 2013 while attending the University of Michigan, Zachary Charles Mutual began performing as a solo acoustic act at local fraternities and house parties within the Ann Arbor, Michigan area.  It was not long until his childhood friend, Dan Drogosh, was brought up on stage to bring a rhythmic element to the duo.  The majority of the house party shows occurred on the University's campus and eventually were streamlined to Drogosh's current residency in East Lansing, Michigan on Michigan State University's campus.  The band's current name, "Mutual Live", originated from the duo's inability to decide on a group name and agreement to use Mutual's last name for the time being.

Irish Catholic Bishops' Conference: The Irish Catholic Bishops' Conference (Irish: "Comhdháil Easpag Caitliceach Éireann" ) is the episcopal conference of the Roman Catholic bishops in Ireland.  The conference meets a number of times a year in Maynooth which is the location of St Patrick's College, Ireland's national seminary.  While each bishop is autonomous in his own diocese, meetings of the conference give bishops a chance to discuss issues of mutual concern, or issues of national policy.

Citharexylum: Citharexylum is a genus of flowering plants in the verbena family, Verbenaceae.  It contains shrub and tree species commonly known as fiddlewoods or zitherwoods.  They are native to the Americas, ranging from southern Florida and Texas in the United States to Argentina.  The highest diversity occurs in Mexico and the Andes.  The generic name is derived from the Greek words κιθάρα ("kithara"), meaning "lyre", and ξύλον ("xylon"), meaning "wood," referring to the use of the wood in the sounding boards of string instruments. Several species, especially "C. caudatum" and "C. spinosum", are cultivated as ornamentals.

IMSI-catcher: An International Mobile Subscriber Identity-catcher, or IMSI-catcher, is a telephone eavesdropping device used for intercepting mobile phone traffic and tracking location data of mobile phone users.  Essentially a "fake" mobile tower acting between the target mobile phone and the service provider's real towers, it is considered a man-in-the-middle (MITM) attack.  The 3G wireless standard mitigates some risk due to mutual authentication required from both the handset and the network.  However, sophisticated attacks may be able to downgrade 3G and LTE to non-LTE network services which do not require mutual authentication.

HyperTrack: HyperTrack is a location platform offering developer tools for large and independent mobile application companies.  Its toolset contains iOS, and Android SDKs which generate live location data, that is then used to build use cases like live order tracking, mileage tracking, workforce monitoring, live location sharing, profiling users and place, and geofencing.
