Input: Question: Is the campus of the university that recognised the London School of Economics as a Faculty of Economics located within the city of London? Passage 1:Scheres worked as a Postdoctoral researcher at the Spanish National Center for Biotechnology (CNB) with José Maria Carazo from 2003-2010, where he developed classification algorithms for Cryogenic electron microscopy (cryo-EM) images based on Maximum likelihood estimation. In 2010 Scheres was appointed as a group leader at the MRC Laboratory of Molecular Biology, Cambridge. There, he extended his maximum-likelihood methods to a general Empirical Bayes method for Protein structure determination by cryo-EM, which he implemented in the computer program RELION. Besides developing algorithms for cryo-EM image processing, Scheres has also collaborated with experimental groups to solve several important protein structures. For example, Xiaochen Bai in his group solved the structure of human Gamma secretase in a collaboration with Shi Yigong, and Anthony Fitzpatrick in his group solved the structure of Amyloid fibrils of Tau protein from the brain of an individual with Alzheimer's disease in a collaboration with Michel Goedert.
 Passage 2:The School expanded rapidly and was moved along with its newly established library, the British Library of Political and Economic Science to No. 10 Adelphi Terrace in September 1896, continuing to expand through the next couple of years thanks to Shaw. In 1902, The Coefficients dining club was regularly meeting in the Library, and they affected the development of LSE along with the Fabians and the Suffragettes movement (who also first met at LSE). In 1900, the School became officially recognised as a Faculty of Economics within the much larger University of London in Bloomsbury, and began enrolling students for bachelor's degrees and doctorates in the same year. At the same time, the LSE began expanding into other areas of social sciences, including, initially, geography (in 1902) and philosophy (in 1903), pioneering the study of international relations, as well as teaching history, law, psychology and sociology. By 1902, it was apparent the School had and would continue to outgrow its Adelphi Terrace location, and moved to its present campus in Clare Market off the Aldwych and aside Kingsway - not far from Whitehall, in 1902. The Old Building, which remains a significant office and classroom building, was opened on Houghton Street in 1922.
 Passage 3:Robert Coull Wellins was born into a showbiz family living in the Gorbals, Glasgow; he later lived in Carnwadric and attended Shawlands Academy. Wellins studied alto saxophone and harmony with his father Max, and also played piano and clarinet when young. He joined the RAF as a musician playing tenor sax. After demobilisation he played with a few Scottish bands before moving to London in the mid-1950s. He was a member of Buddy Featherstonhaugh's quintet between 1956 and 1957, together with Kenny Wheeler. Around that time Wellins also joined drummer Tony Crombie's Jazz Inc., where he first met pianist Stan Tracey, joining Tracey's quartet in the early 1960s. He also worked with Lionel Grigson in 1976. At the end of the 1970s he was a member of the Jim Richardson Quartet.
