Context paragraphs:
Persian Gulf Forever: The Persian Gulf Forever (Persian: "Khalīj-e Hamīshegī-e Fārs" ,خلیج همیشگی فارس‎ ‎ ) or the Persian Gulf (Persian: "Khalīj-e Fārs" ,خلیج فارس‎ ‎ ) also shortly known by Ebi's 1990 album's name The Gulf (Persian: "Khalīj" ,خلیج‎ ‎ ) is a Persian language political, protest and nationalistic song performed by plenty of Iranian singers, inside and outside the country.  Finally, the song became a hit by Ebi Hamedi's version which produced by Mohammad Shams (with co-production by Ebi)ا.  It is the first single from the singer's first 1990s solo album, "Khalij" (English: The Gulf ).  The song is one of the greatest hits of Hamedi.  Persian Gulf Forever was released in 1990 as the album's first single.  Its lyrics was written by "Adel Hasani" to defend Persian Gulf's historic reality, based on Persian Gulf naming dispute started by some Arab politicians especially supported by the governments of the Persian Gulf Arab States in the late 1960s.  This song officially released on the label of Taraneh Records in 1990 in the United States of America and its first live performance was in Paris, France.

Annie Had a Baby: "Annie Had a Baby" is a 1954 rhythm and blues song written by Henry Glover (co-credited to Lois Mann) and recorded by The Midnighters.  The single was one of many answer songs to "Work With Me, Annie", a previous hit for The Midnighters.  "Annie Had a Baby" was also a number one hit on the R&B chart.  A credible inspiration for this song was when a Los Angeles DJ played "Work With Me, Annie" then joked about a follow-up record titled "Annie Had a Baby" which caused King Records to receive orders for the then non-existing single.  So the song was composed, recorded and released to fill the orders.

The Greatest Hit (song): "The Greatest Hit" is a song by Norwegian recording artist Annie.  It was written and produced by Annie and DJ Tore "Erot" Kroknes.  The song samples Madonna's 1982 debut single "Everybody".  The track was released as a limited edition 7-inch single in 1999.  It became an underground club hit in Norway and the United Kingdom.  Retitled "Greatest Hit", the song was later included on Annie's debut album "Anniemal" (2004).

Annie C. Maguire: Annie C. Maguire was a British three-masted barque sailing from Buenos Aires, Argentina, on 24 December 1886 when she struck the ledge at Portland Head Light, Cape Elizabeth, Maine.  Lighthouse Keeper Joshua Strout, his son, wife, and volunteers rigged an ordinary ladder as a gangplank between the shore and the ledge the ship was heeled against.  Captain O'Neil, the ship's master, his wife, two mates, and the nine-man crew clambered onto the ledge and then, one by one, crossed the ladder to safety.

Gulf of Maine Closed Areas: The Gulf of Maine has been fished since the 1700s, and has been a historic fishing area since.  Climate change is having significant impacts on this ecosystem; between 2004 and 2013, the Gulf of Maine has warmed faster than 99.9% of the global oceans, increasing average temperature by 2 °C.  Having seen the depletion of groundfish stocks starting in the early 1990s, managers took care to create five closure areas in the Gulf of Maine.

Clare Maguire: Clare Rita Mary Maguire (born 15 September 1988) is a British singer-songwriter.  She was signed to Universal Music Group, Polydor Records in 2009.  She was rated in fifth place in the BBC Sound of 2011 list of the top 15 most promising new artists.  Maguire was also singled out as one of MTV's Brand New: For 2011 Acts.  Her voice has been compared to Stevie Nicks and Annie Lennox.  Maguire's debut album, "Light After Dark", was released on 25 February 2011 peaking at number seven in the Official UK Top 40, and achieving the BPI Silver Sales Award in the UK.

Protein Structure Evaluation Suite &amp; Server: PROSESS (Protein Structure Evaluation Suite & Server) is a freely available web server for protein structure validation.  It is specifically designed to assist with the process of evaluating and validating protein structures solved by NMR spectroscopy.  Structure validation is a particularly important component of the structure determination pipeline as many protein structures have small structural errors (i.e. distorted bond lengths or angles, incompatible torsion angles, overlapping atoms) that are not easily detected by visual inspection.  For protein structures solved by NMR spectroscopy, where large numbers of structures are generated and where coordinate inaccuracies are common, this problem is particularly acute.  Most NMR-based structure validation protocols primarily use NOE (Nuclear Overhauser Enhancement), J-coupling or residual dipolar coupling (RDC ) data to assess or validate structures.  In particular, they try to assess the agreement between the experimentally observed and the calculated NOEs, RDCs and/or J-couplings. Good agreement between the calculated and observed parameters normally indicates a good structure.  Other methods for structure validation (such as ProCheck, MolProbity, ResProx and [http://VADAR. wishartlab.com/ VADAR]) focus on measuring coordinate data, rather than experimental data, to assess the quality of the bond or torsion angle geometry.  PROSESS is unique among structure validation servers in that it evaluates both coordinate quality and experimental data quality.  Furthermore PROSESS is also able to use NMR chemical shifts (as well as NOEs) to assess or validate protein structures.  Chemical shifts are easily and very precisely measurable NMR observables that provide a great deal of information about protein structure and dynamics (see Protein Chemical Shift Prediction).  Specifically, PROSESS assesses the agreement between observed chemical shifts and ShiftX-predicted HA, CA, CB, N, C, and HN NMR chemical shifts.  In addition to its ability to validate structures using chemical shifts, PROSESS also checks many other protein structure parameters including covalent bond quality, non-covalent bond and atomic packing quality, torsion angle quality and NOE quality (i.e. measuring the model agreement with NOE-based distance restraints).  A total of 8 different programs (see PROSESS sub-programs below) are used in the PROSESS evaluation and validation process.

Annie C. Stewart Memorial Fountain: The Annie C. Stewart Memorial Fountain is a fountain in Madison, the capital of the U.S. state of Wisconsin.  Dedicated to the memory of Annie (Anna) C. Stewart (January 17, 1867 – April 8, 1905), who engaged in charitable activities in Madison, it was constructed in 1917–25 and erected in Henry Vilas Park in 1925.  The fountain is located south of 625 Wingra Street, near the corner of Wingra Street and Erin Street (the former pedestrian entrance of Henry Vilas Zoo) in Vilas Park.  The fountain is adjacent to an eagle effigy mound built by Native Americans overlooking Lake Wingra.

Portland Head Light: Portland Head Light is a historic lighthouse in Cape Elizabeth, Maine.  The light station sits on a head of land at the entrance of the primary shipping channel into Portland Harbor, which is within Casco Bay in the Gulf of Maine.  Completed in 1791, it is the oldest lighthouse in the state of Maine.  The light station is automated, and the tower, beacon, and foghorn are maintained by the United States Coast Guard, while the former lighthouse keepers' house is a maritime museum within Fort Williams Park.

Corossol crater: The Corossol structure, which is also known as the Corossol crater, is a circular, 4.3 by in diameter, underwater bedrock feature that is exposed on the gulf floor of the northwestern Gulf of Saint Lawrence 20 km offshore of the city of Sept-Îles, Quebec in eastern Canada.  It is hypothesized to be a possible pre-Pleistocene, extraterrestrial impact structure.  It lies underwater at a depth of 40 - .  This underwater feature was found during the study of high-resolution bathymetric and sub-bottom profiler data collected south of the city of Sept-Iles in the northwestern Gulf of Saint Lawrence.
