Question: Herbert Parker was born in which English town that is commonly abbreviated by locals to "Accy"?
Context: Poulton-le-Fylde ( ), commonly abbreviated to Poulton, is a market town in Lancashire, England, situated on the coastal plain called the Fylde.  In the 2001 United Kingdom census, it had a population of 18,264.  There is evidence of human habitation in the area from 12,000 years ago and several archaeological finds from Roman settlement in England have been found in the area.  At the time of the Norman conquest Poulton was a small agricultural settlement in the hundred of Amounderness.  The church of St Chad was recorded in 1094 when it was endowed to Lancaster Priory.  By the post-Medieval period the town had become an important commercial centre for the region with weekly and triannual markets.  Goods were imported and exported through two harbours on the River Wyre.  In 1837, the town was described as the "metropolis of the Fylde", but its commercial importance waned from the mid-19th century with the development of the nearby coastal towns of Fleetwood and Blackpool. The Enhanced Integrated Framework for Trade-Related Assistance for the Least Developed Countries (commonly abbreviated as EIF) is a global development program with the objective of supporting least developed countries (LDCs) to better integrate into the global trading system and to make trade a driver for development.  The multi-donor program was launched on 1 January 2007 as the successor of the Integrated Framework for Trade-Related Technical Assistance to the Least-Developed Countries (commonly abbreviated as IF), which existed from October 1997 to December 2006.  The second phase of the EIF has started on 1 January 2016 and will last for 7 years. China Shanghai Shenzhen 300 Stock Index Futures, often abbreviated to "Hushen 300 Index" (Shanghai is commonly abbreviated in Chinese as Hù，and Shenzhen is abbreviated as shēn), designated by the commodity ticker symbol IF, is a stock market index futures contract traded in China Financial Futures Exchange (CFFEX).  The notional value of one contract is RMB￥300 (1.00 USD = 6.83 RMB) times the value of the Shanghai Shenzhen 300 Stock Index. Triethylamine is the chemical compound with the formula N(CHCH), commonly abbreviated EtN.  It is also abbreviated TEA, yet this abbreviation must be used carefully to avoid confusion with triethanolamine or tetraethylammonium, for which TEA is also a common abbreviation.  It is a colourless volatile liquid with a strong fishy odor reminiscent of ammonia and is also the smell of the hawthorn plant.  Like diisopropylethylamine (Hünig’s base), triethylamine is commonly encountered in organic synthesis. James Ralston Kennedy "RP" Paterson, CBE, MC, MD, FRCSEd, FRCR, DMRE (Cantab) (21 May 1897 – 29 August 1981) was a radiologist and oncologist in Scotland.  Along with Herbert Parker, pioneered the development of the Paterson-Parker rules for the "Radium Dosage System" also known as the Manchester system. Herbert Parker (March 2, 1856 - ?) , of Lancaster, Worcester County, Massachusetts, was a Massachusetts politician. Herbert M. Parker (13 April 1910, Accrington – 5 March 1984, Richland, Washington) was an English, and American immigrant, medical physicist.  He was a pioneer of medical radiation therapy and radiation safety, known for introducing the roentgen equivalent physical (rep), the forerunner of the gray and the rad, and also the roentgen equivalent biological (reb), the forerunner of the rem and the sievert. Accrington is a town in the Hyndburn borough of Lancashire, England.  It lies about 4 mi east of Blackburn, 6 mi west of Burnley, 13 mi east of Preston, 20 mi north of Manchester city centre and is situated on the mostly culverted River Hyndburn.  Commonly abbreviated by locals to "Accy", the town has a population of 54,800 according to the 2001 census and the urban area has a population of over 85,000. The Indian Sudoku Championship (commonly abbreviated as 'ISC') is an annual national contest held in India to crown the Indian Sudoku Champion and to select the national team for the World Sudoku Championship.  It usually consists of multiple rounds of solving various sudoku variants and the scores of players are aggregated for the final rankings.  It is conducted by Logic Masters India (commonly abbreviated as 'LMI'), which is the Indian affiliate of the World Puzzle Federation. The Röntgen equivalent physical or rep (symbol rep) is a unit of absorbed dose first introduced by Herbert Parker in 1945 to replace an improper application of the roentgen unit to biological tissue.  It is the absorbed energetic dose before the biological efficiency of the radiation is factored in.  The rep has variously been defined as 83 or 93 ergs per gram of tissue (8.3/9.3 mGy) or per cm of tissue.  At the time, this was thought to be the amount of energy deposited by 1 roentgen.  Improved measurements have since found that one roentgen of air kerma deposits 8.77 mGy in dry air, or 9.6 mGy in soft tissue, but the rep was defined as a fixed number of ergs per unit gram.  A 1952 handbook from the US National Bureau of Standards affirms that "The numerical coefficient of the rep has been deliberately changed to 93, instead of the earlier 83, to agree with L. H. Gray's 'energy-unit'."  It is unclear what was meant by Gray's 'energy unit', since the gray was not defined until the 1970s; perhaps the gram-roentgen he introduced in 1940?  The rep was commonly used until the 1960s, but was gradually displaced by the rad starting in 1954 and later the gray starting in 1977.
