Question: What is the population of the town where Gawler established his own firm? Passage 1:Maryanoff has been active in the fields of medicinal chemistry and organic chemistry. He is an inventor of topiramate, a unique sugar sulfamate drug, which has been marketed worldwide for the treatment of epilepsy and migraine, attaining annual sales of more than $2 billion. Topiramate is also a principal component of the antiobesity drug Qsymia. Maryanoff is an internationally renowned expert in drug design and drug discovery, especially in the application of protein structure-based drug design. He made seminal contributions to understanding the stereochemistry and mechanism of the Wittig reaction; adapted the cobalt-catalyzed alkyne trimerization to the synthesis of macrocycles; and devised novel peptides that undergo self-assembly to mimic native collagen structurally and functionally. Maryanoff is an author on 280 scientific publications, including several books (editor), book chapters, and review articles. He is an inventor on 100 issued U.S. patents, has presented over 185 invited lectures worldwide, and mentored 11 postdoctoral associates. Maryanoff organized and edited a special memorial issue of the Journal of Medicinal Chemistry to honor the memory of Dr. Paul Janssen (2005) and has served on numerous editorial advisory boards for scientific journals and research grant review committees.
 Passage 2:Gawler was born in Adelaide, South Australia, to Caroline (née Philpot) and Henry Gawler. His grandfather, George Gawler, was the second Governor of South Australia. Gawler attended St Peter's College, Adelaide, and then studied law at the University of Adelaide. Gawler was called to the bar in South Australia in 1886, and left for Western Australia later that year, establishing his own firm in Perth. At one time, he was in partnership with Robert Bruce Burnside, a future Supreme Court justice. Having previously served on the Peppermint Grove Road Board for a period, Gawler was elected to parliament at a 1910 Legislative Council by-election, which had been caused by the resignation of Walter Kingsmill. He died in office in May 1915 (aged 54), of typhoid fever. He had married Eva Mary Waldeck in 1893, with whom he had four children.
 Passage 3:Benfica's first competitive game was an away Primeira Liga opener against Rio Ave. Sánchez Flores did not have Reyes, and Jonathan Urretaviscaya started instead. At the Estádio dos Arcos, the home team scored first with a 55th-minute goal from José Semedo. A minute later Benfica evened the score, with Urreta assisting Nuno Gomes for the 1–1 final result. It was the fourth consecutive time that Benfica failed to win their league start. Sánchez Flores said that Rio Ave created unexpected problems: "It was not a easy game. We had a quality opponent, who left us trailing when we were not expecting it." During the last week of August Benfica brought in Honduran striker David Suazo on loan, sold right-back Nélson Marcos to Betis and was paired with Italian side Napoli in the UEFA Cup first-round draw on 29 August. A day later, Benfica hosted Porto for the first Clássico of the season. The visitors started better, converting a 10th-minute penalty kick for a Kostas Katsouranis foul against Lucho González. In the 56th minute, Cardozo exploited a mistake by Helton to head in the equaliser. Three minutes later Katsouranis was sent off, but Benfica held the tie until the final whistle. Quique Flores said, "It was a good game. In normal conditions we would have done better, but circumstances made it a little harder."

He was also briefly the Video Recordings Authority in 1994, a member of the Indecent Publications Tribunal from 1990 to 1994 and Deputy President of the Film and Literature Board of Review from 1995 to 1998. In 2010 he stood down as Chief Censor when he became a District Court Judge and Chair of the Immigration and Protection Tribunal. He was succeeded by Andrew Jack.
 Passage 2:Kanazawa was born in Iruma on July 9, 1976. After graduating from Kokushikan University, he joined J1 League club Júbilo Iwata in 1999. Although he could not become a regular player, he played many matches as left side midfielder from first season. The club won the champions 1999 and 2002 J1 League. In Asia, the club won the champions 1998–99 Asian Club Championship and the 2nd place 1999–00 and 2000–01 Asian Club Championship. In 2003, he moved to FC Tokyo. He became a regular player as left side back from first season. The club won the champions 2004 J.League Cup. Although he could hardly play in the match for injury in 2006, he came back and became a regular player again in 2007. From 2008, he lost regular position behind newcomer Yuto Nagatomo and he also played as defensive midfielder not only left side back. In August 2009, he moved to Júbilo Iwata for the first time in 7 years. He played as regular left side back in 2009 season. Although he could not play many matches from 2010, the club won the champions 2010 J.League Cup. His opportunity to play decreased from 2011 and he moved to J2 League club Thespakusatsu Gunma in 2014. He retired end of 2014 season at the age of 38.
 Passage 3:Most Deep Learning systems rely on training and verification data that is generated and/or annotated by humans. It has been argued in media philosophy that not only low-payed clickwork (e.g. on Amazon Mechanical Turk) is regularly deployed for this purpose, but also implicit forms of human microwork that are often not recognized as such. The philosopher Rainer Mühlhoff distinguishes five types of "machinic capture" of human microwork to generate training data: (1) gamification (the embedding of annotation or computation tasks in the flow of a game), (2) "trapping and tracking" (e.g. CAPTCHAs for image recognition or click-tracking on Google search results pages), (3) exploitation of social motivations (e.g. tagging faces on Facebook to obtain labeled facial images), (4) information mining (e.g. by leveraging quantified-self devices such as activity trackers) and (5) clickwork. Mühlhoff argues that in most commercial end-user applications of Deep Learning such as Facebook's face recognition system, the need for training data does not stop once an ANN is trained. Rather, there is a continued demand for human-generated verification data to constantly calibrate and update the ANN. For this purpose Facebook introduced the feature that once a user is automatically recognized in an image, they receive a notification. They can choose whether of not they like to be publicly labeled on the image, or tell Facebook that it is not them in the picture. This user interface is a mechanism to generate "a constant stream of  verification data" to further train the network in real-time. As Mühlhoff argues, involvement of human users to generate training and verification data is so typical for most commercial end-user applications of Deep Learning that such systems may be referred to as "human-aided artificial intelligence".

Question: How long was Steve Jobs away from apple before returning? Passage 1:The Japanese exhibition at the fair was the product of years of preparation. The empire had received its invitation in 1871, close on the heels of the Meiji Restoration, and a government bureau was established to produce an appropriate response. Shigenobu Okuma, Tsunetami Sano, and its other officials were keen to use the event to raise the international standing of Japanese manufactures and boost exports. 24 engineers were also sent with its delegation to study cutting-edge Western engineering at the fair for use in Japanese industry. Art and cultural relics at the exhibit were verified by the Jinshin Survey, a months-long inspection tour of various imperial, noble, and temple holdings around the country. The most important products of each province were listed and two specimens of each were collected, one for display in Vienna and the other for preservation and display within Japan. Large-scale preparatory exhibitions with this second set of objects were conducted within Japan at the Tokyo Kaisei School (today the University of Tokyo) in 1871 and at the capital's Confucian Temple in 1872; they eventually formed the core collection of the institution that became the Tokyo National Museum. 
 Passage 2:Fawcus served during World War One and was promoted to the rank of lieutenant colonel in March 1915. He was made a member of the Order of St Michael and St George in the 1915 Birthday Honours. He was made a temporary colonel in April 1917. He awarded the Croix de guerre by France in June 1917. Throughout the course of the war, Fawcus was mentioned in dispatches six times. Following the war, he was promoted to the rank of brevet colonel in June 1919, and in the same year he served in the Third Anglo-Afghan War. He served as an assistant director-general at the War Office from June 1922–July 1926. He was appointed as the honorary physician to George V in January 1923, following the retirement of Sir Alfred Blenkinsop. He was promoted to the full rank of colonel in June 1926, with appointment in the same month as a deputy director-general at the War Office. He was promoted to the rank of major-general in October 1926. He was knighted in the 1928 Birthday Honours. He was appointed as the director-general of Army Medical Services in September 1929, at which point he was promoted to the rank of lieutenant-general. He was made a member of the Order of the Bath in the 1931 New Year Honours. Fawcus was presented with an honorary degree in civil law by Durham University in 1930. He served as the director-general of Army Medical Services until his retirement from active service in March 1934. Following his retirement he was replaced as the personal physician for George V by J. W. L. Scott. While serving as director-general, he won the General's Cup in golf at Sandwich in 1931.
 Passage 3:Due to the sales growth of IBM clones in the '90s, they became the industry standard for business and home use. This growth was augmented by the introduction of Microsoft's Windows 3.0 operating environment in 1990, and followed by Windows 3.1 in 1992 and the Windows 95 operating system in 1995. The Macintosh was sent into a period of decline by these developments coupled with Apple's own inability to come up with a successor to the Macintosh operating system, and by 1996 Apple was almost bankrupt. In December 1996 Apple bought NeXT and in what has been described as a "reverse takeover", Steve Jobs returned to Apple in 1997. The NeXT purchase and Jobs' return brought Apple back to profitability, first with the release of Mac OS 8, a major new version of the operating system for Macintosh computers, and then with the PowerMac G3 and iMac computers for the professional and home markets. The iMac was notable for its transparent bondi blue casing in an ergonomic shape, as well as its discarding of legacy devices such as a floppy drive and serial ports in favor of Ethernet and USB connectivity. The iMac sold several million units and a subsequent model using a different form factor remains in production as of August 2017. In 2001 Mac OS X, the long-awaited "next generation" Mac OS based on the NeXT technologies was finally introduced by Apple, cementing its comeback.
