synth_fc_2797_rep12 | Positive | Physics & Chemistry | Database creation | Multi | https://en.wikipedia.org/wiki/Abiogenesis | 29 | Chemiosmotic gradient
Russell demonstrated that alkaline vents created an abiogenic proton motive force chemiosmotic gradient, ideal for abiogenesis. Their microscopic compartments "provide a natural means of concentrating organic molecules," composed of iron-sulfur minerals such as mackinawite, endowed these mineral cells with the catalytic properties envisaged by Günter Wächtershäuser. This movement of ions across the membrane depends on a combination of two factors:
These two gradients taken together can be expressed as an electrochemical gradient, providing energy for abiogenic synthesis. The proton motive force can be described as the measure of the potential energy stored as a combination of proton and voltage gradients across a membrane (differences in proton concentration and electrical potential).
The surfaces of mineral particles inside deep-ocean hydrothermal vents have catalytic properties similar to those of enzymes and can create simple organic molecules, such as methanol (CH OH) and formic, acetic, and pyruvic acids out of the dissolved CO in the water, if driven by an applied voltage or by reaction with H or H S.
The research reported by Martin in 2016 supports the thesis that life arose at hydrothermal vents, that spontaneous chemistry in the Earth's crust driven by rock–water interactions at disequilibrium thermodynamically underpinned life's origin and that the founding lineages of the archaea and bacteria were H -dependent autotrophs that used CO as their terminal acceptor in energy metabolism. Martin suggests, based upon this evidence, that the LUCA "may have depended heavily on the geothermal energy of the vent to survive". Pores at deep sea hydrothermal vents are suggested to have been occupied by membrane-bound compartments which promoted biochemical reactions. Metabolic intermediates in the Krebs cycle, gluconeogenesis, amino acid bio-synthetic pathways, glycolysis, the pentose phosphate pathway, and including sugars like ribose, and lipid precursors can occur non-enzymatically at conditions relevant to deep-sea alkaline hydrothermal vents.
If the deep marine hydrothermal setting was the site for the origin of life, then abiogenesis could have happened as early as 4.0-4.2 Gya. If life evolved in the ocean at depths of more than ten meters, it would have been shielded both from impacts and the then high levels of ultraviolet radiation from the sun. The available energy in hydrothermal vents is maximized at 100–150 °C, the temperatures at which hyperthermophilic bacteria and thermoacidophilic archaea live. Arguments against a hydrothermal origin of life state that hyperthermophily was a result of convergent evolution in bacteria and archaea, and that a mesophilic environment would have been more likely. This hypothesis, suggested in 1999 by Galtier, was proposed one year before the discovery of the Lost City Hydrothermal Field, where white-smoker hydrothermal vents average ~45-90 °C. Moderate temperatures and alkaline seawater at Lost City are now the favoured hydrothermal vent setting in contrast to acidic, high temperature (~350 °C) black-smokers. |

Lloyd Webber's new version of Cinderella opened at the Gillian Lynne Theatre in the West End in 2021. The opening, which was originally set to take place in August 2020, was delayed due to the COVID-19 pandemic. Based on a book by Emerald Fennell, Lloyd Webber wrote: "Emerald Fennell has written something truly exciting and original, and the moment I read her outline I knew I'd found my latest collaborator." He garnered press attention in July 2021 for saying that he was "prepared to be arrested" to open Cinderella to full houses in spite of rising Covid cases and in defiance of Government advice. A 2021 feature in Variety suggested:
Lloyd Webber, at 73, appears to have been reanimated creatively in recent years. Both School of Rock and Cinderella earned him some of the best reviews of his career and had a lightness and wit that had been missing from his work. They came after a grueling period in the wilderness, one characterized by failures, disappointments and missteps.... It seemed, for a time, as though the Lloyd Webber formula, which relied on swooning, rapturous melodies and razzle-dazzle, had grown stale.
In 2022, Lloyd Webber appeared alongside Lin-Manuel Miranda in the BBC Platinum Jubilee Concert for Platinum Jubilee of Elizabeth II. They initially appeared singing alternative words to "The King's Song" from Jesus Christ Superstar and " Any Dream Will Do " from Joseph and the Amazing Technicolor Dreamcoat and " The Phantom of the Opera " from The Phantom of the Opera were parts of the musical theatre section.
In 2023, Lloyd Webber was one of twelve composers asked to write a new piece for the coronation of Charles III and Camilla. His anthem, "Make a Joyful Noise", was performed during the enthronement of Queen Camilla. |
synth_fc_1757_rep10 | Positive | Health | Calculation | Single | https://en.wikipedia.org/wiki/Lysosome | 9 | Function and structure
Lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). The enzymes responsible for this hydrolysis require an acidic environment for optimal activity.
In addition to being able to break down polymers, lysosomes are capable of fusing with other organelles & digesting large structures or cellular debris; through cooperation with phagosomes, they are able to conduct autophagy, clearing out damaged structures. Similarly, they are able to break down virus particles or bacteria in phagocytosis of macrophages.
The size of lysosomes varies from 0.1 μm to 1.2 μm. With a pH ranging from ~4.5–5.0, the interior of the lysosomes is acidic compared to the slightly basic cytosol (pH 7.2). The lysosomal membrane protects the cytosol, and therefore the rest of the cell, from the degradative enzymes within the lysosome. The cell is additionally protected from any lysosomal acid hydrolases that drain into the cytosol, as these enzymes are pH-sensitive and do not function well or at all in the alkaline environment of the cytosol. This ensures that cytosolic molecules and organelles are not destroyed in case there is leakage of the hydrolytic enzymes from the lysosome.
The lysosome maintains its pH differential by pumping in protons (H ions) from the cytosol across the membrane via proton pumps and chloride ion channels. Vacuolar-ATPases are responsible for transport of protons, while the counter transport of chloride ions is performed by ClC-7 Cl /H antiporter. In this way a steady acidic environment is maintained.
It sources its versatile capacity for degradation by import of enzymes with specificity for different substrates; cathepsins are the major class of hydrolytic enzymes, while lysosomal alpha-glucosidase is responsible for carbohydrates, and lysosomal acid phosphatase is necessary to release phosphate groups of phospholipids.
Recent research also indicates that lysosomes can act as a source of intracellular calcium. |

Guinea pigs (called cuy, cuye, or curí) were originally domesticated for their meat in the Andes. Traditionally, the animal was reserved for ceremonial meals and as a delicacy by indigenous people in the Andean highlands. Still, since the 1960s, it has become more socially acceptable for consumption by all people. It continues to be a significant part of the diet in Peru and Bolivia, particularly in the Andes Mountains highlands; it is also eaten in some areas of Ecuador (mainly in the Sierra) and in Colombia, mainly in the southwestern part of the country (Cauca and Nariño departments). Because guinea pigs require much less room than traditional livestock and reproduce extremely quickly, they are a more profitable source of food and income than many traditional stock animals, such as pigs and cattle; moreover, they can be raised in an urban environment. Both rural and urban families raise guinea pigs for supplementary income, and the animals are commonly bought and sold at local markets and large-scale municipal fairs.
Guinea pig meat is high in protein and low in fat and cholesterol, and is described as being similar to rabbit and the dark meat of chicken. The animal may be served fried (chactado or frito), broiled (asado), or roasted (al horno), and in urban restaurants may also be served in a casserole or a fricassee. Ecuadorians commonly consume sopa or locro de cuy, a soup dish. Pachamanca or huatia, an earth oven cooking method, is also popular, and cuy cooked this way is usually served with chicha (corn beer) in traditional settings. |

Due to the success of the Olympic football tournaments, FIFA, with President Jules Rimet as the driving force, again started looking at staging its own international tournament outside of the Olympics. On 28 May 1928, the FIFA Congress in Amsterdam decided to stage a world championship. With Uruguay now two-time official football world champions and to celebrate their centenary of independence in 1930, FIFA named Uruguay as the host country of the inaugural World Cup tournament.
The national associations of selected nations were invited to send a team, but the choice of Uruguay as a venue for the competition meant a long and costly trip across the Atlantic Ocean for European sides, especially in the midst of the Great Depression. As such, no European country pledged to send a team until two months before the start of the competition. Rimet eventually persuaded teams from Belgium, France, Romania, and Yugoslavia to make the trip. In total, 13 nations took part: seven from South America, four from Europe, and two from North America.
The first two World Cup matches took place simultaneously on 13 July 1930, and were won by France and the United States, who defeated Mexico 4–1 and Belgium 3–0 respectively. The first goal in World Cup history was scored by Lucien Laurent of France. In the final, Uruguay defeated Argentina 4–2 in front of 93,000 spectators in Montevideo, and became the first nation to win the World Cup. After the creation of the World Cup, FIFA and the IOC disagreed over the status of amateur players; football was dropped from the 1932 Summer Olympics. After the IOC and FIFA worked out their differences, Olympic football returned at the 1936 Summer Olympics, but was now overshadowed by the more prestigious World Cup.
The issues facing the early World Cup tournaments were the difficulties of intercontinental travel, and war. Few South American teams were willing to travel to Europe for the 1934 World Cup and all North and South American nations except Brazil and Cuba boycotted the 1938 tournament. Brazil was the only South American team to compete in both. The 1942 and 1946 competitions, which Germany and Brazil sought to host, were cancelled due to World War II. |
synth_fc_1353_rep8 | Negative | Food | Entity search | Single | https://en.wikipedia.org/wiki/Cricket_(insect) | 1 | Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms, "crickets" were placed at the family level (i.e. Gryllidae), but contemporary authorities including Otte now place them in the superfamily Grylloidea. The word has been used in combination to describe more distantly related taxa in the suborder Ensifera, such as king crickets and mole crickets.
Crickets have mainly cylindrically shaped bodies, round heads, and long antennae. Behind the head is a smooth, robust pronotum. The abdomen ends in a pair of long cerci; females have a long, cylindrical ovipositor. Diagnostic features include legs with 3-segmented tarsi; as with many Orthoptera, the hind legs have enlarged femora, providing power for jumping. The front wings are adapted as tough, leathery elytra, and some crickets chirp by rubbing parts of these together. The hind wings are membranous and folded when not in use for flight; many species, however, are flightless. The largest members of the family are the bull crickets, Brachytrupes, which are up to 5 cm (2 in) long.
Crickets are distributed all around the world except at latitudes 55° or higher, with the greatest diversity being in the tropics. They occur in varied habitats from grassland, bushes, and forests to marshes, beaches, and caves. Crickets are mainly nocturnal, and are best known for the loud, persistent, chirping song of males trying to attract females, although some species are mute. The singing species have good hearing, via the tympana on the tibiae of the front legs.
Crickets often appear as characters in literature. The Talking Cricket features in Carlo Collodi 's 1883 children's book, The Adventures of Pinocchio, and in films based on the book. The insect is central to Charles Dickens 's 1845 The Cricket on the Hearth and George Selden 's 1960 The Cricket in Times Square. Crickets are celebrated in poems by William Wordsworth, John Keats, Du Fu and Vladimir Nazor. They are kept as pets in countries from China to Europe, sometimes for cricket fighting. Crickets are efficient at converting their food into body mass, making them a candidate for food production. They are used as human food in Southeast Asia, where they are sold deep-fried in markets as snacks. They are also used to feed carnivorous pets and zoo animals. In Brazilian folklore, crickets feature as omens of various events. |

An entrenched clause or entrenchment clause of a basic law or constitution is a provision that makes certain amendments either more difficult or impossible to pass, making such amendments inadmissible. Overriding an entrenched clause may require a supermajority, a referendum, or the consent of the minority party. For example, the U.S. Constitution has an entrenched clause that prohibits abolishing equal suffrage of the States within the Senate without their consent. The term eternity clause is used in a similar manner in the constitutions of the Czech Republic, Germany, Turkey, Greece, Italy, Morocco, the Islamic Republic of Iran, Brazil and Norway. India's constitution does not contain specific provisions on entrenched clauses but the basic structure doctrine makes it impossible for certain basic features of the Constitution to be altered or destroyed by the Parliament of India through an amendment. The Constitution of Colombia also lacks explicit entrenched clauses, but has a similar substantive limit on amending its fundamental principles through judicial interpretations. |

An approximate randomization test is based on a specified subset of all permutations (which entails potentially enormous housekeeping of which permutations have been considered). The Monte Carlo approach is based on a specified number of randomly drawn permutations (exchanging a minor loss in precision if a permutation is drawn twice—or more frequently—for the efficiency of not having to track which permutations have already been selected). |

She is known for her unconventional style of pop music and introspective songwriting. Lorde expressed interest in performing at local venues in her early teens. She signed with Universal Music Group (UMG) in 2009 and collaborated with producer Joel Little in 2011. Their first effort, an extended play (EP) titled The Love Club, was self-released in 2012 for free download on SoundCloud before it was commercially released in 2013. The EP's single "Royals" reached number one in Canada, New Zealand, the United Kingdom, and the United States, where it spent nine weeks atop the Billboard Hot 100. It sold 10 million units worldwide, making it one of the best-selling singles of all time. Her debut studio album Pure Heroine was released that same year to critical and commercial success. The following year, Lorde curated the soundtrack for the 2014 film The Hunger Games: Mockingjay – Part 1. Lorde partnered with producer Jack Antonoff for her second studio album Melodrama (2017), which received widespread critical acclaim and debuted atop the US Billboard 200. The album has since been ranked in Rolling Stone's list of the "500 Greatest Albums of All Time" and Pitchfork's list of the "Greatest Albums of the 2010s". For her third studio album, Solar Power (2021), she ventured into indie folk and psychedelic styles. The album reached number one in Australia and New Zealand and the top-10 in numerous other countries, although it polarised music critics and fans alike. Lorde's accolades include two Grammy Awards, two Brit Awards, and a nomination for a Golden Globe Award.

synth_fc_1441_rep21 | Positive | Geography | Calculation | Single | https://en.wikipedia.org/wiki/Europe | 25 | Early modern period
The Renaissance was a period of cultural change originating in Florence, and later spreading to the rest of Europe. The rise of a new humanism was accompanied by the recovery of forgotten classical Greek and Arabic knowledge from monastic libraries, often translated from Arabic into Latin. The Renaissance spread across Europe between the 14th and 16th centuries: it saw the flowering of art, philosophy, music, and the sciences, under the joint patronage of royalty, the nobility, the Roman Catholic Church and an emerging merchant class. Patrons in Italy, including the Medici family of Florentine bankers and the Popes in Rome, funded prolific quattrocento and cinquecento artists such as Raphael, Michelangelo and Leonardo da Vinci.
Political intrigue within the Church in the mid-14th century caused the Western Schism. During this forty-year period, two popes—one in Avignon and one in Rome—claimed rulership over the Church. Although the schism was eventually healed in 1417, the papacy's spiritual authority had suffered greatly. In the 15th century, Europe started to extend itself beyond its geographic frontiers. Spain and Portugal, the greatest naval powers of the time, took the lead in exploring the world. Exploration reached the Southern Hemisphere in the Atlantic and the southern tip of Africa. Christopher Columbus reached the New World in 1492, and Vasco da Gama opened the ocean route to the East linking the Atlantic and Indian Oceans in 1498. The Portuguese-born explorer Ferdinand Magellan reached Asia westward across the Atlantic and the Pacific Oceans in a Spanish expedition, resulting in the first circumnavigation of the globe, completed by the Spaniard Juan Sebastián Elcano (1519–1522). Soon after, the Spanish and Portuguese began establishing large global empires in the Americas, Asia, Africa and Oceania. France, the Netherlands and England soon followed in building large colonial empires with vast holdings in Africa, the Americas and Asia. In 1588, a Spanish armada failed to invade England. A year later England tried unsuccessfully to invade Spain, allowing Philip II of Spain to maintain his dominant war capacity in Europe. This English disaster also allowed the Spanish fleet to retain its capability to wage war for the next decades. However, two more Spanish armadas failed to invade England (2nd Spanish Armada and 3rd Spanish Armada).
The Church's power was further weakened by the Protestant Reformation in 1517 when German theologian Martin Luther nailed his Ninety-five Theses criticising the selling of indulgences to the church door. He was subsequently excommunicated in the papal bull Exsurge Domine in 1520 and his followers were condemned in the 1521 Diet of Worms, which divided German princes between Protestant and Roman Catholic faiths. Religious fighting and warfare spread with Protestantism. The plunder of the empires of the Americas allowed Spain to finance religious persecution in Europe for over a century. The Thirty Years' War (1618–1648) crippled the Holy Roman Empire and devastated much of Germany, killing between 25 and 40 percent of its population. In the aftermath of the Peace of Westphalia, France rose to predominance within Europe. The defeat of the Ottoman Turks at the Battle of Vienna in 1683 marked the historic end of Ottoman expansion into Europe.
The 17th century in Central and parts of Eastern Europe was a period of general decline; the region experienced more than 150 famines in a 200-year period between 1501 and 1700. From the Union of Krewo (1385) east-central Europe was dominated by the Kingdom of Poland and the Grand Duchy of Lithuania. The hegemony of the vast Polish–Lithuanian Commonwealth had ended with the devastation brought by the Second Northern War (Deluge) and subsequent conflicts; the state itself was partitioned and ceased to exist at the end of the 18th century.
From the 15th to 18th centuries, when the disintegrating khanates of the Golden Horde were conquered by Russia, Tatars from the Crimean Khanate frequently raided Eastern Slavic lands to capture slaves. Further east, the Nogai Horde and Kazakh Khanate frequently raided the Slavic-speaking areas of contemporary Russia and Ukraine for hundreds of years, until the Russian expansion and conquest of most of northern Eurasia (i.e. Eastern Europe, Central Asia and Siberia).
The Renaissance and the New Monarchs marked the start of an Age of Discovery, a period of exploration, invention and scientific development. Among the great figures of the Western scientific revolution of the 16th and 17th centuries were Copernicus, Kepler, Galileo and Isaac Newton. According to Peter Barrett, "It is widely accepted that 'modern science' arose in the Europe of the 17th century (towards the end of the Renaissance), introducing a new understanding of the natural world." |
synth_fc_122_rep15 | Positive | Biology | Entity search | Single | https://en.wikipedia.org/wiki/Saccharomyces_cerevisiae | 2 | Invasive and systemic infections
Occasionally Saccharomyces cerevisiae causes invasive infections (i. e. gets into the bloodstream or other normally sterile body fluid or into a deep site tissue, such as lungs, liver or spleen) that can go systemic (involve multiple organs). Such conditions are life-threatening. More than 30% cases of S. cerevisiae invasive infections lead to death even if treated. S. cerevisiae invasive infections, however, are much rarer than invasive infections caused by Candida albicans even in patients weakened by cancer. S. cerevisiae causes 1% to 3.6% nosocomial cases of fungemia. A comprehensive review of S. cerevisiae invasive infection cases found all patients to have at least one predisposing condition.
Saccharomyces cerevisiae may enter the bloodstream or get to other deep sites of the body by translocation from oral or enteral mucosa or through contamination of intravascular catheters (e. g. central venous catheters). Intravascular catheters, antibiotic therapy and compromised immunity are major predisposing factors for S. cerevisiae invasive infection.
A number of cases of fungemia were caused by intentional ingestion of living S. cerevisiae cultures for dietary or therapeutic reasons, including use of Saccharomyces boulardii (a strain of S. cerevisiae which is used as a probiotic for treatment of certain forms of diarrhea). Saccharomyces boulardii causes about 40% cases of invasive Saccharomyces infections and is more likely (in comparison to other S. cerevisiae strains) to cause invasive infection in humans without general problems with immunity, though such adverse effect is very rare relative to Saccharomyces boulardii therapeutic administration.
S. boulardii may contaminate intravascular catheters through hands of medical personnel involved in administering probiotic preparations of S. boulardii to patients.
Systemic infection usually occurs in patients who have their immunity compromised due to severe illness (HIV/AIDS, leukemia, other forms of cancer) or certain medical procedures (bone marrow transplantation, abdominal surgery).
A case was reported when a nodule was surgically excised from a lung of a man employed in baking business, and examination of the tissue revealed presence of Saccharomyces cerevisiae. Inhalation of dry baking yeast powder is supposed to be the source of infection in this case. |

A game's payoff matrix is a convenient representation. Consider these situations as an example, the two-player zero-sum game pictured at right or above.
The order of play proceeds as follows: The first player (red) chooses in secret one of the two actions 1 or 2; the second player (blue), unaware of the first player's choice, chooses in secret one of the three actions A, B or C. Then, the choices are revealed and each player's points total is affected according to the payoff for those choices.
Example: Red chooses action 2 and Blue chooses action B. When the payoff is allocated, Red gains 20 points and Blue loses 20 points.
In this example game, both players know the payoff matrix and attempt to maximize the number of their points. Red could reason as follows: "With action 2, I could lose up to 20 points and can win only 20, and with action 1 I can lose only 10 but can win up to 30, so action 1 looks a lot better." With similar reasoning, Blue would choose action C. If both players take these actions, Red will win 20 points. If Blue anticipates Red's reasoning and choice of action 1, Blue may choose action B, so as to win 10 points. If Red, in turn, anticipates this trick and goes for action 2, this wins Red 20 points.
Émile Borel and John von Neumann had the fundamental insight that probability provides a way out of this conundrum. Instead of deciding on a definite action to take, the two players assign probabilities to their respective actions, and then use a random device which, according to these probabilities, chooses an action for them. Each player computes the probabilities so as to minimize the maximum expected point-loss independent of the opponent's strategy. This leads to a linear programming problem with the optimal strategies for each player. This minimax method can compute probably optimal strategies for all two-player zero-sum games.
For the example given above, it turns out that Red should choose action 1 with probability 4 / 7 and action 2 with probability 3 / 7, and Blue should assign the probabilities 0, 4 / 7, and 3 / 7 to the three actions A, B, and C. Red will then win 20 / 7 points on average per game. |

Some coffeehouses may serve cold beverages, such as iced coffee and iced tea, as well as other non-caffeinated beverages. A coffeehouse may also serve food, such as light snacks, sandwiches, muffins, cakes, breads, donuts or pastries. In continental Europe, some cafés also serve alcoholic beverages. Coffeehouses range from owner-operated small businesses to large multinational corporations. Some coffeehouse chains operate on a franchise business model, with numerous branches across various countries around the world. While café may refer to a coffeehouse, the term "café" can also refer to a diner, British café, "greasy spoon", transport café, teahouse or tea room, or other casual eating and drinking place. A coffeehouse may share some of the same characteristics of a bar or restaurant, but it is different from a cafeteria. Many coffeehouses in West Asia offer shisha, flavored tobacco smoked through a hookah. An espresso bar is a type of coffeehouse that specializes in serving espresso and espresso-based drinks. From a cultural standpoint coffeehouses largely serve as centers of social interaction: a coffeehouse provides patrons with a place to congregate, talk, read, write, entertain one another, or pass the time, whether individually or in small groups. A coffeehouse can serve as an informal social club for its regular members. As early as the 1950s Beatnik era and the 1960s folk music scene, coffeehouses have hosted singer-songwriter performances, typically in the evening. The digital age saw the rise of the Internet café along similar principles. |

Beginning in 1997, Havel hosted Forum 2000, an annual conference to "identify the key issues facing civilisation and to explore ways to prevent the escalation of conflicts that have religion, culture or ethnicity as their primary components". In 2005, the former president occupied the Kluge Chair for Modern Culture at the John W. Kluge Center of the United States Library of Congress, where he continued his research on human rights. In November and December 2006, Havel spent eight weeks as a visiting artist in residence at Columbia University. The stay was sponsored by the Columbia Arts Initiative and featured "performances, and panels centr on his life and ideas", including a public "conversation" with former U.S. President Bill Clinton. Concurrently, the Untitled Theater Company No. 61 launched a Havel Festival, the first complete festival of his plays in various venues throughout New York City, including The Brick Theater and the Ohio Theatre, in celebration of his 70th birthday. Havel was a member of the World Future Society and addressed the Society's members on 4 July 1994. His speech was later printed in THE FUTURIST magazine (July 1995).
Havel was greatly admired by Czech citizens. In the poll taken for the 2005 TV show Největší Čech (the Czech spin-off of the BBC 100 Greatest Britons), Havel placed third.
Havel's memoir of his experience as president, To the Castle and Back, was published in May 2007. The book mixes an interview in the style of Disturbing the Peace with actual memoranda he sent to his staff and modern diary entries and recollections.
On 4 August 2007, Havel met with members of the Belarus Free Theatre at his summer cottage in the Czech Republic in a show of his continuing support, which has been instrumental in the theatre's attaining international recognition and membership in the European Theatrical Convention.
Havel went on a hunger strike in 2007 to support Kurdish doctor and human rights activist Yekta Uzunoglu in his legal battle. A former president going on a hunger strike to support the legal battle of a foreigner in his country was a first in world history.
Havel's first new play in almost two decades, Leaving, was published in November 2007, and was to have had its world premiere in June 2008 at the Prague Vinohrady Theatre, but the theater withdrew it in December as it felt it could not provide the technical support needed to mount the play. The play instead premiered on 22 May 2008 at the Archa Theatre to standing ovations. Havel based the play on King Lear, by William Shakespeare, and on The Cherry Orchard, by Anton Chekhov; "Chancellor Vilém Rieger is the central character of Leaving, who faces a crisis after being removed from political power." The play had its English language premiere at the Orange Tree Theatre in London and its American premiere at The Wilma Theater in Philadelphia. Havel subsequently directed a film version of the play, which premiered in the Czech Republic on 22 March 2011.
Other works included the short sketch Pět Tet, a modern sequel to Unveiling, and The Pig, or Václav Havel's Hunt for a Pig, which was premiered in Brno at Theatre Goose on a String and had its English language premiere at the 3LD Art & Technology Center in New York, in a production from Untitled Theater Company No. 61, in a production workshopped in the Ice Factory Festival in 2011 and later revived as a full production in 2014, becoming a New York Times Critic's Pick.
In 2008, Havel became a Member of the European Council on Tolerance and Reconciliation. He met U.S. President Barack Obama in private before Obama's departure after the end of the European Union (EU) and United States (US) summit in Prague in April 2009. Havel was the chair of the Human Rights Foundation 's International Council and a member of the international advisory council of the Victims of Communism Memorial Foundation.
Havel was a supporter of the Campaign for the Establishment of a United Nations Parliamentary Assembly, an organisation which campaigns for democratic reformation of the United Nations, and the creation of a more accountable international political system. From the 1980s, Havel supported the green politics movement, partly due to his friendship with the co-founder of the German Alliance 90/The Greens party Milan Horáček. From 2004 until his death, he supported the Czech Green Party. |

Some scientists estimate that a nuclear war with 100 Hiroshima-size nuclear explosions on cities could cost the lives of tens of millions of people from long-term climatic effects alone. The climatology hypothesis is that if each city firestorms, a great deal of soot could be thrown up into the atmosphere which could blanket the earth, cutting out sunlight for years on end, causing the disruption of food chains, in what is termed a nuclear winter.
People near the Hiroshima explosion and who managed to survive the explosion subsequently suffered a variety of horrible medical effects. Some of these effects are still present to this day:
Fallout exposure—depending on if further afield individuals shelter in place or evacuate perpendicular to the direction of the wind, and therefore avoid contact with the fallout plume, and stay there for the days and weeks after the nuclear explosion, their exposure to fallout, and therefore their total dose, will vary. With those who do shelter in place, and or evacuate, experiencing a total dose that would be negligible in comparison to someone who just went about their life as normal.
Staying indoors until after the most hazardous fallout isotope, I-131 decays away to 0.1% of its initial quantity after ten half-lifes —which is represented by 80 days in I-131s case, would make the difference between likely contracting Thyroid cancer or escaping completely from this substance depending on the actions of the individual. |
synth_fc_2450_rep21 | Positive | Movie | Entity search | Multi | https://en.wikipedia.org/wiki/Computer_monitor | 22 | Liquid-crystal display
There are multiple technologies that have been used to implement liquid-crystal displays (LCD). Throughout the 1990s, the primary use of LCD technology as computer monitors was in laptops where the lower power consumption, lighter weight, and smaller physical size of LCDs justified the higher price versus a CRT. Commonly, the same laptop would be offered with an assortment of display options at increasing price points: (active or passive) monochrome, passive color, or active matrix color (TFT). As volume and manufacturing capability have improved, the monochrome and passive color technologies were dropped from most product lines.
TFT-LCD is a variant of LCD which is now the dominant technology used for computer monitors.
The first standalone LCDs appeared in the mid-1990s selling for high prices. As prices declined they became more popular, and by 1997 were competing with CRT monitors. Among the first desktop LCD computer monitors were the Eizo FlexScan L66 in the mid-1990s, the SGI 1600SW, Apple Studio Display and the ViewSonic VP140 in 1998. In 2003, LCDs outsold CRTs for the first time, becoming the primary technology used for computer monitors. The physical advantages of LCD over CRT monitors are that LCDs are lighter, smaller, and consume less power. In terms of performance, LCDs produce less or no flicker, reducing eyestrain, sharper image at native resolution, and better checkerboard contrast. On the other hand, CRT monitors have superior blacks, viewing angles, and response time, can use arbitrary lower resolutions without aliasing, and flicker can be reduced with higher refresh rates, though this flicker can also be used to reduce motion blur compared to less flickery displays such as most LCDs. Many specialized fields such as vision science remain dependent on CRTs, the best LCD monitors having achieved moderate temporal accuracy, and so can be used only if their poor spatial accuracy is unimportant.
High dynamic range (HDR) has been implemented into high-end LCD monitors to improve grayscale accuracy. Since around the late 2000s, widescreen LCD monitors have become popular, in part due to television series, motion pictures and video games transitioning to widescreen, which makes squarer monitors unsuited to display them correctly. |
synth_fc_2413_rep26 | Negative | Movie | Recommendation | Single | https://en.wikipedia.org/wiki/The_Lion_King | 1 | The Lion King is a 1994 American animated musical coming-of-age drama film produced by Walt Disney Feature Animation and released by Buena Vista Pictures Distribution under the Walt Disney Pictures banner. The film was directed by Roger Allers and Rob Minkoff and produced by Don Hahn, from a screenplay written by Irene Mecchi, Jonathan Roberts, and Linda Woolverton. The film features an ensemble voice cast that includes Matthew Broderick, Moira Kelly, James Earl Jones, Jeremy Irons, Jonathan Taylor Thomas, Niketa Calame, Nathan Lane, Ernie Sabella, Whoopi Goldberg, Cheech Marin, Rowan Atkinson, and Robert Guillaume. Its original songs were written by composer Elton John and lyricist Tim Rice, with a score by Hans Zimmer. Inspired by African wildlife, the story is modelled primarily on William Shakespeare's stage play Hamlet with some influence from the Biblical stories of Joseph and Moses, and follows a young heir apparent who is forced to flee after his uncle kills his father and usurps the throne. After growing up in exile, the rightful king returns to challenge the usurper and end his tyrannical rule over the kingdom. Initially, The Lion King was supposed to be a non-musical, leaning towards a style similar to that of a documentary. George Scribner, who had made his feature directorial debut with Oliver & Company (1988), was hired to direct, with Allers joining him soon after following his work as a story artist or head of story on Oliver & Company, The Little Mermaid (1989), Beauty and the Beast (1991), and Aladdin (1992). Allers brought in Brenda Chapman and Chris Sanders, whom he had worked with on Beauty and the Beast and Aladdin, to serve as head of story and production designer, respectively. Woolverton, who had just wrapped up work as screenwriter for Beauty and the Beast, wrote the initial draft of the screenplay for this film, but following her departure from the project to write the libretto for the Broadway adaptation of Beauty and the Beast, Mecchi and Roberts were brought on board to finish and revise the script. Six months into production, Scribner left the project due to creative differences with Allers, producer Hahn, and Chapman about changing it into a musical, and Minkoff was hired to replace him in April 1992. Additionally, Beauty and the Beast directors Gary Trousdale and Kirk Wise were hired to perform some additional rewrites to the script and story. Throughout production, Allers, Scribner, Minkoff, Hahn, Chapman, Sanders, and several other animators visited Kenya to observe wildlife and get inspiration for the characters and setting. The Lion King was released on June 15, 1994, receiving critical acclaim for its music, story, themes, and animation. With an initial worldwide gross of $763 million, it finished its theatrical run as the highest-grossing film of 1994 and the second-highest-grossing film of all time, behind Jurassic Park (1993). It also held the title of being the highest-grossing animated film, until it was overtaken by Finding Nemo (2003). The film remains the highest-grossing traditionally animated film of all time, as well as the best-selling film on home video, having sold over 55 million copies worldwide. It received two Academy Awards, as well as the Golden Globe Award for Best Motion Picture – Musical or Comedy. It is considered by many to be among the greatest animated films ever made. The film has led to many derived works, such as a Broadway adaptation in 1997; two direct-to-video follow-ups—the sequel, The Lion King II: Simba's Pride (1998), and the prequel/parallel, The Lion King 1½ (2004); two television series, The Lion King's Timon & Pumbaa (1995-1999) and The Lion Guard (2016-2019), the latter which premiered as a television film titled The Lion Guard: Return of the Roar in 2015; and a photorealistic remake in 2019, which also became the highest-grossing animated film at the time of its release. In 2016, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". The Lion King is the first Disney film to have been dubbed in Zulu, the only African language aside from Egyptian Arabic to have been used for a feature-length Disney dub. |

The most important aspect and defining characteristic of protein from a nutritional standpoint is its amino acid composition. There are multiple systems which rate proteins by their usefulness to an organism based on their relative percentage of amino acids and, in some systems, the digestibility of the protein source. They include biological value, net protein utilization, and PDCAAS (Protein Digestibility Corrected Amino Acids Score) which was developed by the FDA as a modification of the Protein efficiency ratio (PER) method. The PDCAAS rating was adopted by the US Food and Drug Administration (FDA) and the Food and Agricultural Organization of the United Nations/ World Health Organization (FAO/WHO) in 1993 as "the preferred 'best'" method to determine protein quality. These organizations have suggested that other methods for evaluating the quality of protein are inferior. In 2013 FAO proposed changing to Digestible Indispensable Amino Acid Score. |
synth_fc_3121_rep6 | Negative | Sport | Ranking | Single | https://en.wikipedia.org/wiki/Hank_Aaron | 11 | Breaking Ruth's career home run record
Aaron himself downplayed the "chase" to surpass Babe Ruth, while baseball enthusiasts and the national media grew increasingly excited as he closed in on the 714 career home runs record. Aaron received thousands of letters every week during the summer of 1973, including hate mail; he ended up asking a secretary working for the Braves, Carla Koplin, to help him sort through it.
Aaron (then age 39) hit 40 home runs in 392 at-bats, ending the 1973 season one home run short of the record. He hit home run number 713 on September 29, 1973, and with one day remaining in the season, many expected him to tie the record. But in his final game that year, playing against the Houston Astros (managed by Leo Durocher, who had once roomed with Babe Ruth), he was unable to achieve this. After the game, Aaron said his only fear was that he might not live to see the 1974 season.
He was the recipient of death threats and a large assortment of hate mail during the 1973–1974 offseason from people who did not want to see Aaron break Ruth's nearly sacrosanct home run record. The threats extended to those providing positive press coverage of Aaron. Lewis Grizzard, then-executive sports editor of The Atlanta Journal, reported receiving numerous phone calls calling journalists "nigger lovers" for covering Aaron's chase. While preparing the massive coverage of the home run record, Grizzard quietly had an obituary written, afraid that Aaron might be murdered.
Sports Illustrated pointedly summarized the racist vitriol that Aaron was forced to endure:
Is this to be the year in which Aaron, at the age of thirty-nine, takes a moon walk above one of the most hallowed individual records in American sport...? Or will it be remembered as the season in which Aaron, the most dignified of athletes, was besieged with hate mail and trapped by the cobwebs and goblins that lurk in baseball's attic?
At the end of the 1973 season, Aaron received a plaque from the U.S. Postal Service for receiving more mail (930,000 pieces) than any person excluding politicians. Aaron received an outpouring of public support in response to the bigotry. In August 1973, Peanuts cartoonist Charles Schulz drew a series of strips in which Snoopy attempts to break Babe Ruth's record, only to be besieged with hate mail. In the strip published August 11, Lucy remarked to Snoopy: "Hank Aaron is a great player... but you! If you break Babe Ruth's record, it'll be a disgrace!" Coincidentally, Snoopy was only one home run short of tying the record (and finished the season as such when Charlie Brown got picked off second base during Snoopy's last at-bat), and as it turned out, Aaron finished the 1973 season one home run short of Ruth. Babe Ruth's widow, Claire, denounced the racism and declared that her husband would have enthusiastically cheered Aaron's attempt at the record. As the 1974 season began, Aaron's pursuit of the record caused a small controversy. The Braves opened the season on the road in Cincinnati with a three-game series against the Cincinnati Reds. Braves management wanted him to break the record in Atlanta and was therefore going to have Aaron sit out the first three games of the season. But Baseball Commissioner Bowie Kuhn ruled that he had to play two games in the first series. He played two out of three and tied Babe Ruth's record on April 4, 1974, in his very first at-bat on his first swing of the season—off Reds pitcher Jack Billingham, but did not hit another home run in the series.
The Braves returned to Atlanta, and on April 8, 1974, a crowd of 53,775 people showed up for the game—a Braves attendance record. The game was also broadcast nationally on NBC. In the fourth inning, Aaron hit home run number 715 off Los Angeles Dodgers pitcher Al Downing. Although Dodgers outfielder Bill Buckner nearly went over the outfield fence trying to catch it, the ball flew into the Braves' bullpen and the First National Bank advertisement sign in left-center field, where relief pitcher Tom House caught it. While cannons were fired in celebration, two college students sprinted onto the field and jogged alongside Aaron for part of his circuit around the bases, temporarily startling him. As the fans cheered wildly, Aaron's parents ran onto the field as well. Afterwards, Aaron remarked how "I never knew my mother could hug so tight," though he later learned that Aaron's mother kept hugging him because she was worried someone could try to shoot Aaron, and she thought nobody would try to shoot him if she was hugging him. Braves announcer Milo Hamilton, calling the game on WSB radio, described the scene as Aaron broke the record:
Henry Aaron, in the second inning, walked and scored. He's sittin' on 714. Here's the pitch by Downing. Swinging. There's a drive into left-center field. That ball is gonna be-eee... Outta here! It's gone! It's 715! There's a new home run champion of all time, and it's Henry Aaron! The fireworks are going. Henry Aaron is coming around third. His teammates are at home plate. And listen to this crowd!
Meanwhile, Dodgers broadcaster Vin Scully addressed the racial tension—or apparent lack thereof—in his call of the home run:
What a marvelous moment for baseball; what a marvelous moment for Atlanta and the state of Georgia; what a marvelous moment for the country and the world. A black man is getting a standing ovation in the Deep South for breaking a record of an all-time baseball idol. And it is a great moment for all of us, and particularly for Henry Aaron... And for the first time in a long time, that poker face in Aaron shows the tremendous strain and relief of what it must have been like to live with for the past several months. |
synth_fc_3627_rep28 | Positive | Video game | Entity search | Single | https://en.wikipedia.org/wiki/Quaternion | 24 | Quaternions as the even part of Cl (R)
The usefulness of quaternions for geometrical computations can be generalised to other dimensions by identifying the quaternions as the even part Cl 3, 0 + (R) {\displaystyle \operatorname {Cl} _{3,0}^{+}(\mathbb {R})} of the Clifford algebra Cl 3, 0 (R). {\displaystyle \operatorname {Cl} _{3,0}(\mathbb {R}).} This is an associative multivector algebra built up from fundamental basis elements σ, σ, σ using the product rules
σ 1 2 = σ 2 2 = σ 3 2 = 1, {\displaystyle \sigma _{1}^{2}=\sigma _{2}^{2}=\sigma _{3}^{2}=1,} σ i σ j = − σ j σ i (j ≠ i). {\displaystyle \sigma _{i}\sigma _{j}=-\sigma _{j}\sigma _{i}\qquad (j\neq i).}
If these fundamental basis elements are taken to represent vectors in 3D space, then it turns out that the reflection of a vector r in a plane perpendicular to a unit vector w can be written:
r ′ = − w r w. {\displaystyle r^{\prime }=-w\,r\,w.}
Two reflections make a rotation by an angle twice the angle between the two reflection planes, so
r ′ ′ = σ 2 σ 1 r σ 1 σ 2 {\displaystyle r^{\prime \prime }=\sigma _{2}\sigma _{1}\,r\,\sigma _{1}\sigma _{2}}
corresponds to a rotation of 180° in the plane containing σ and σ. This is very similar to the corresponding quaternion formula,
r ′ ′ = − k r k. {\displaystyle r^{\prime \prime }=-\mathbf {k} \,r\,\mathbf {k}.}
Indeed, the two structures Cl 3, 0 + (R) {\displaystyle \operatorname {Cl} _{3,0}^{+}(\mathbb {R})} and H {\displaystyle \mathbb {H} } are isomorphic. One natural identification is
1 ↦ 1, i ↦ − σ 2 σ 3, j ↦ − σ 3 σ 1, k ↦ − σ 1 σ 2, {\displaystyle 1\mapsto 1\,,\quad \mathbf {i} \mapsto -\sigma _{2}\sigma _{3}\,,\quad \mathbf {j} \mapsto -\sigma _{3}\sigma _{1}\,,\quad \mathbf {k} \mapsto -\sigma _{1}\sigma _{2}\,,}
and it is straightforward to confirm that this preserves the Hamilton relations
i 2 = j 2 = k 2 = i j k = − 1. {\displaystyle \mathbf {i} ^{2}=\mathbf {j} ^{2}=\mathbf {k} ^{2}=\mathbf {i\,j\,k} =-1~.}
In this picture, so-called "vector quaternions" (that is, pure imaginary quaternions) correspond not to vectors but to bivectors – quantities with magnitudes and orientations associated with particular 2D planes rather than 1D directions. The relation to complex numbers becomes clearer, too: in 2D, with two vector directions σ and σ, there is only one bivector basis element σ σ, so only one imaginary. But in 3D, with three vector directions, there are three bivector basis elements σ σ, σ σ, σ σ, so three imaginaries.
This reasoning extends further. In the Clifford algebra Cl 4, 0 (R), {\displaystyle \operatorname {Cl} _{4,0}(\mathbb {R}),} there are six bivector basis elements, since with four different basic vector directions, six different pairs and therefore six different linearly independent planes can be defined. Rotations in such spaces using these generalisations of quaternions, called rotors, can be very useful for applications involving homogeneous coordinates. But it is only in 3D that the number of basis bivectors equals the number of basis vectors, and each bivector can be identified as a pseudovector.
There are several advantages for placing quaternions in this wider setting:

The major sports in Belize are football, basketball, volleyball and cycling, with smaller followings of boat racing, athletics, softball, cricket and rugby. Fishing is also popular in coastal areas of Belize.
The Cross Country Cycling Classic, also known as the "cross country" race or the Holy Saturday Cross Country Cycling Classic, is considered one of the most important Belize sports events. This one-day sports event is meant for amateur cyclists but has also gained worldwide popularity. The history of Cross Country Cycling Classic in Belize dates back to the period when Monrad Metzgen picked up the idea from a small village on the Northern Highway (now Phillip Goldson Highway). The people from this village used to cover long distances on their bicycles to attend the weekly game of cricket. He improvised on this observation by creating a sporting event on the difficult terrain of the Western Highway, which was then poorly built.
Another major annual sporting event in Belize is the La Ruta Maya Belize River Challenge, a 4-day canoe marathon held each year in March. The race runs from San Ignacio to Belize City, a distance of 290 kilometres (180 mi).
On Easter day, citizens of Dangriga participate in a yearly fishing tournament. First, second, and third prize are awarded based on a scoring combination of size, species, and number. The tournament is broadcast over local radio stations, and prize money is awarded to the winners.
The Belize national basketball team is the only national team that has achieved major victories internationally. The team won the 1998 CARICOM Men's Basketball Championship, held at the Civic Centre in Belize City, and subsequently participated in the 1999 Centrobasquet Tournament in Havana. The national team finished seventh of eight teams after winning only 1 game despite playing close all the way. In a return engagement at the 2000 CARICOM championship in Barbados, Belize placed fourth. Shortly thereafter, Belize moved to the Central American region and won the Central American Games championship in 2001.
The team has failed to duplicate this success, most recently finishing with a 2–4 record in the 2006 COCABA championship. The team finished second in the 2009 COCABA tournament in Cancun, Mexico where it went 3–0 in group play. Belize won its opening match in the Centrobasquet Tournament, 2010, defeating Trinidad and Tobago, but lost badly to Mexico in a rematch of the COCABA final. A tough win over Cuba set Belize in position to advance, but they fell to Puerto Rico in their final match and failed to qualify.

synth_fc_1589_rep11 | Positive | Geography | Calculation | Single | https://en.wikipedia.org/wiki/Caligula | 26 | Bridge at Baiae
In 39 or 40, by Suetonius' reckoning, Caligula ordered a temporary floating bridge to be built using a double line of ships as pontoons, earth-paved and stretching for over two miles from the resort of Baiae, near Naples, to the neighbouring port of Puteoli, with resting places between. Some ships were built on site but grain ships were also requisitioned, brought to site, secured and temporarily resurfaced. Any practical purpose for the bridge is unclear; Winterling believes that it might have been intended to mark Caligula's attempted invasion of Britain. A two-day ceremonial was performed, with offerings to the sea-god Neptune and Invidia (Envy), and a satisfactory result, in that the sea remained completely calm. The bridge was said to rival the Persian king Xerxes' pontoon bridge across the Hellespont.
For the opening ceremony, Caligula donned the supposed breastplate of Alexander the Great, and rode his favourite horse, Incitatus, across the bridge, perhaps defying a prediction, attributed by Suetonius to Tiberius' soothsayer Thrasyllus of Mendes, that Caligula had "no more chance of becoming emperor than of riding a horse across the Bay of Baiae". On the second day, he rode the bridge from end to end several times "at full tilt", accompanied by the soldiery, famous nobles and hostages. Seneca and Dio claim that grain imports were dangerously depleted by Caligula's re-purposing of Rome's grain ships as pontoons. Barrett finds these accusations absurd; if the bridge was finished in 39, that was far too early to have had any effect on the annual grain supply, and "a genuine grain crisis was simply blamed on the most outlandish episode at hand." Dio places this episode soon after Caligula's furious denunciation of the Senate; Barrett speculates that Caligula may have intended the whole event as an object lesson on how completely he was in charge: it may also provide "the most striking example of his wasteful extravagance"; its pointlessness might have been the whole point. |

synth_fc_663_rep2 | Positive | Currency | Calculation | Single | https://en.wikipedia.org/wiki/ASEAN | 15 | Monetary union
The concept of an Asian Currency Unit (ACU) started in the middle of the 1990s, prior to the 1997 Asian financial crisis. It is a proposed basket of Asian currencies, similar to the European Currency Unit, which was the precursor of the Euro. The Asian Development Bank is responsible for exploring the feasibility and construction of the basket. Since the ACU is being considered to be a precursor to a common currency, it has a dynamic outlook of the region. The overall goal of a common currency is to contribute to the financial stability of a regional economy, including price stability. It means lower cost of cross-border business through the elimination of currency risk. Greater flows of intra-trade would put pressure on prices, resulting in cheaper goods and services. Individuals benefit not only from the lowering of prices, they save by not having to change money when travelling, by being able to compare prices more readily, and by the reduced cost of transferring money across borders.
However, there are conditions for a common currency: the intensity of intra-regional trade and the convergence of macroeconomic conditions. Substantial intra-ASEAN trade (which is growing, partly as a result of the ASEAN Free Trade Area (AFTA) and the ASEAN Economic Community.) and economic integration is an incentive for a monetary union. Member states currently trade more with other countries (80%) than among themselves (20%). Therefore, their economies are more concerned about currency stability against major international currencies, like the US dollar. On macroeconomic conditions, member states have different levels of economic development, capacity, and priorities that translate into different levels of interest and readiness. Monetary integration, however, implies less control over national monetary and fiscal policy to stimulate the economy. Therefore, greater convergence in macroeconomic conditions is being enacted to improve conditions and confidence in a common currency. Other concerns include weaknesses in the financial sectors, inadequacy of regional-level resource pooling mechanisms and institutions required to form and manage a currency union, and lack of political preconditions for monetary co-operation and a common currency. |

synth_fc_1941_rep15 | Positive | History | Document search | Multi | https://en.wikipedia.org/wiki/Saladin | 22 | Western world
Saladin was widely renowned in medieval Europe as a model of kingship, and in particular of the courtly virtue of regal generosity. As early as 1202/03, Walther von der Vogelweide urged the German King Philip of Swabia to be more like Saladin, who believed that a king's hands should have holes to let the gold fall through. By the 1270s, Jans der Enikel was spreading the fictitious but approving story of Saladin's table, which presented him as both pious and wise to religious diversity. In The Divine Comedy (1308–1320), Dante mentions him as one of the virtuous non-Christians in limbo, and he is also depicted favorably in Boccaccio's The Decameron (1438–53).
Although Saladin faded into history after the Middle Ages, he appears in a sympathetic light in modern literature, first in Lessing 's play Nathan the Wise (1779), which transfers the central idea of "Saladin's table" to the post-medieval world. He is a central character in Sir Walter Scott 's novel The Talisman (1825), which more than any other single text influenced the romantic view of Saladin. Scott presented Saladin as a "modern liberal European gentlemen, beside whom medieval Westerners would always have made a poor showing". 20th-century French author Albert Champdor described him as "Le plus pur héros de l'Islam" (English: The purest Hero of Islam). Despite the Crusaders' slaughter when they originally conquered Jerusalem in 1099, Saladin granted amnesty and free passage to all common Catholics and even to the defeated Christian army, as long as they were able to pay the aforementioned ransom (the Greek Orthodox Christians were treated even better because they often opposed the western Crusaders).
Notwithstanding the differences in beliefs, the Muslim Saladin was respected by Christian lords, Richard especially. Richard once praised Saladin as a great prince, saying that he was, without doubt, the greatest and most powerful leader in the Islamic world. Saladin, in turn, stated that there was not a more honorable Christian lord than Richard. After the treaty, Saladin and Richard sent each other many gifts as tokens of respect but never met face to face. In April 1191, a Frankish woman's three-month-old baby had been stolen from her camp and sold on the market. The Franks urged her to approach Saladin herself with her grievance. According to Ibn Shaddad, Saladin used his own money to buy the child back:
He gave it to the mother and she took it; with tears streaming down her face, and hugged the baby to her chest. The people were watching her and weeping and I (Ibn Shaddad) was standing amongst them. She suckled it for some time and then Saladin ordered a horse to be fetched for her and she went back to camp.
Mark Cartwright, the publishing director of World History Encyclopedia, writes: "Indeed, it is somewhat ironic that the Muslim leader became one of the great exemplars of chivalry in 13th century European literature. Much has been written about the sultan during his own lifetime and since, but the fact that an appreciation for his diplomacy and leadership skills can be found in both contemporary Muslim and Christian sources would suggest that Saladin is indeed worthy of his position as one of the great medieval leaders." |

Portugal has divided their property taxation into two brackets, pre-purchase taxes and post-purchase taxes (of property).
Pre-Purchase/ Purchasing Real Estate Taxes: If an individual is looking to buy real estate in Portugal, they can be expected to pay a multitude of taxes. First, the individual will have to pay the 'Portugal Property Transfer Tax' (as referred to as 'IMPOSTO MUNICIPAL SOBRE AS TRANSMISSÕES ONEROSAS DE IMÓVEIS). This tax is applied when there is a transfer of ownership of a certain property. The rates of this tax can range from as low as 1% and up to 8%-- these taxes are dependent on a few considerations, which include "the purchase price for the real estate, the location of the property, and whether it is the first or second home in Portugal." In addition, a 'Stamp Tax' (Imposto de Selo) will also be a prepurchase tax applied before the sale of real estate. This is one of the oldest taxes in Portugal, and it is applied to all the official paperwork, such as deeds, contracts, mortgage agreements, and bank statements that make the sale legal and 'official' according to the courts. This responsibility "is accounted for by the buyer, charged at a fixed rate of 0.8% of the property’s registered fiscal value."
Post Purchase Real Estate Taxes: Property Tax (also known as: “IMI – Imposto Municipal Sobre Imóveis”) is "computed on the tax registration value of urban and rural properties located in Portuguese territory." IMI is based on the type of property one possesses: "Urban property- 0.3 to 0.45%, Rural property- 0.8% Property owned by residents in offshores (except individuals)- 7.5%." There are also quite a few tax reductions and exemptions individuals can qualify/ take advantage of properties that are considered a permanent residence (only viable for three years), residencies that have an occupant with multiple dependents registered to them, property that is deemed low in value and is owned by individuals of a low socio-economic standard according to the government, property that is considered a part of the tourism circuit, property that can help with renewable energy and even stores deemed historical or culturally impactful. |

The archeological site is located in Tinúm Municipality, Yucatán State, Mexico. Chichén Itzá was a major focal point in the Northern Maya Lowlands from the Late Classic through the Terminal Classic and into the early portion of the Postclassic period. The site exhibits a multitude of architectural styles, reminiscent of styles seen in central Mexico and of the Puuc and Chenes styles of the Northern Maya lowlands. The presence of central Mexican styles was once thought to have been representative of direct migration or even conquest from central Mexico, but most contemporary interpretations view the presence of these non-Maya styles more as the result of cultural diffusion. Chichén Itzá was one of the largest Maya cities and it was likely to have been one of the mythical great cities, or Tollans, referred to in later Mesoamerican literature. The city may have had the most diverse population in the Maya world, a factor that could have contributed to the variety of architectural styles at the site. The ruins of Chichén Itzá are federal property, and the site's stewardship is maintained by Mexico's Instituto Nacional de Antropología e Historia. The land under the monuments had been privately owned until 29 March 2010, when it was purchased by the state of Yucatán. Chichén Itzá is one of the most visited archeological sites in Mexico with over 2.6 million tourists in 2017. |

synth_fc_2815_rep14 | Positive | Physics & Chemistry | Database search | Multi | https://en.wikipedia.org/wiki/Collatz_conjecture | 21 | Statement of the problem
Consider the following operation on an arbitrary positive integer:
In modular arithmetic notation, define the function f as follows: f (n) = { n / 2 if n ≡ 0 (mod 2), 3 n + 1 if n ≡ 1 (mod 2). {\displaystyle f(n)={\begin{cases}n/2&{\text{if }}n\equiv 0{\pmod {2}},\\3n+1&{\text{if }}n\equiv 1{\pmod {2}}.\end{cases}}}
Now form a sequence by performing this operation repeatedly, beginning with any positive integer, and taking the result at each step as the input at the next.
In notation: a i = { n for i = 0, f (a i − 1) for i > 0 {\displaystyle a_{i}={\begin{cases}n&{\text{for }}i=0,\\f(a_{i-1})&{\text{for }}i>0\end{cases}}} (that is: a is the value of f applied to n recursively i times; a = f (n)).
The Collatz conjecture is: This process will eventually reach the number 1, regardless of which positive integer is chosen initially. That is, for each n {\displaystyle n}, there is some i {\displaystyle i} with a i = 1 {\displaystyle a_{i}=1}.
If the conjecture is false, it can only be because there is some starting number which gives rise to a sequence that does not contain 1. Such a sequence would either enter a repeating cycle that excludes 1, or increase without bound. No such sequence has been found.
The smallest i such that a < a is called the stopping time of n. Similarly, the smallest k such that a = 1 is called the total stopping time of n. If one of the indexes i or k doesn't exist, we say that the stopping time or the total stopping time, respectively, is infinite.
The Collatz conjecture asserts that the total stopping time of every n is finite. It is also equivalent to saying that every n ≥ 2 has a finite stopping time.
Since 3 n + 1 is even whenever n is odd, one may instead use the "shortcut" form of the Collatz function: f (n) = { n 2 if n ≡ 0 (mod 2), 3 n + 1 2 if n ≡ 1 (mod 2). {\displaystyle f(n)={\begin{cases}{\frac {n}{2}}&{\text{if }}n\equiv 0{\pmod {2}},\\{\frac {3n+1}{2}}&{\text{if }}n\equiv 1{\pmod {2}}.\end{cases}}} This definition yields smaller values for the stopping time and total stopping time without changing the overall dynamics of the process. |

Although the war was largely treated with indifference in metropolitan France, "the dirty war" has been featured in various films, books and songs. Since its declassification in the 2000s, television documentaries have been released using new perspectives about the U.S. covert involvement and open critics about the French propaganda used during wartime.The famous Communist propagandist Roman Karmen was in charge of the media exploitation of the battle of Dien Bien Phu. In his documentary, Vietnam (Вьетнам, 1955), he staged the famous scene with the raising of the Việt Minh flag over de Castries' bunker which is similar to the one he staged over the Berlin Reichstag roof during World War II (Берлин, 1945) and the S-shaped POW column marching after the battle, where he used the same optical technique he experimented with before when he staged the German prisoners after the Siege of Leningrad (Ленинград в борьбе, 1942) and the Battle of Moscow (Разгром немецких войск под Москвой, 1942). Hollywood made a film about Dien Bien Phu in 1955, Jump into Hell, directed by David Butler and scripted by Irving Wallace, before his fame as a bestselling novelist. Hollywood also made several films about the war, Robert Florey 's Rogues' Regiment (1948). Samuel Fuller 's China Gate (1957). and James Clavell 's Five Gates to Hell (1959).The first French movie about the war, Shock Patrol (Patrouille de Choc) aka Patrol Without Hope (Patrouille Sans Espoir) by Claude Bernard-Aubert, came out in 1956. The French censor cut some violent scenes and made the director change the end of his movie which was seen as " too pessimistic". Léo Joannon 's film Fort du Fou (Fort of the Mad) / Outpost in Indochina was released in 1963. Another film was The 317th Platoon (La 317ème Section) was released in 1964, it was directed by Indochina War (and siege of Dien Bien Phu) veteran Pierre Schoendoerffer. Schoendoerffer has since become a media specialist about the Indochina War and has focused his production on realistic war movies. He was cameraman for the army ("Cinematographic Service of the Armies", SCA) during his duty time; moreover, as he had covered the Vietnam War he released The Anderson Platoon, which won the Academy Award for Documentary Feature. Graham Greene 's novel The Quiet American takes place during this war.In 2011, Vietnamese software developer Emobi Games released a first-person-shooter called 7554. Named after the date 07-05-54 (7 May 1954) which marks the end of the decisive Battle of Dien Bien Phu, it commemorates the First Indochina War from the Vietnamese point of view.The 2017 film by Olivier Lorelle, Ciel Rouge, starring Cyril Descours and Audrey Giacomini, is set during the early part of the First Indochina War. |
synth_fc_731_rep8 | Positive | DNA sequence | Generation | Single | https://en.wikipedia.org/wiki/Genetic_code | 9 | Start and stop codons
Translation starts with a chain-initiation codon or start codon. The start codon alone is not sufficient to begin the process. Nearby sequences such as the Shine-Dalgarno sequence in E. coli and initiation factors are also required to start translation. The most common start codon is AUG, which is read as methionine or as formylmethionine (in bacteria, mitochondria, and plastids). Alternative start codons depending on the organism include "GUG" or "UUG"; these codons normally represent valine and leucine, respectively, but as start codons they are translated as methionine or formylmethionine.
The three stop codons have names: UAG is amber, UGA is opal (sometimes also called umber), and UAA is ochre. Stop codons are also called "termination" or "nonsense" codons. They signal release of the nascent polypeptide from the ribosome because no cognate tRNA has anticodons complementary to these stop signals, allowing a release factor to bind to the ribosome instead. |

Buffett worked from 1951 to 1954 at his father's firm, Buffett-Falk & Co., as an investment salesman; from 1954 to 1956 at Graham-Newman Corp. as a securities analyst; from 1956 to 1969 at several investment partnerships as the general partner; and from 1970 as chairman and CEO of Berkshire Hathaway Inc.
In 1951, Buffett discovered that Graham was on the board of GEICO insurance. Taking a train to Washington, D.C., on a Saturday, he knocked on the door of GEICO's headquarters until a janitor admitted him. There he met Lorimer Davidson, GEICO's vice president, and the two discussed the insurance business for hours, and Buffett made his first purchase of GEICO stock. Davidson would eventually become Buffett's lifelong friend and a lasting influence, and would later recall that he found Buffett to be an "extraordinary man" after only fifteen minutes. Buffett wanted to work on Wall Street but both his father and Ben Graham urged him not to. He offered to work for Graham for free, but Graham refused.
Buffett returned to Omaha and worked as a stockbroker while taking a Dale Carnegie public speaking course. Using what he learned, he felt confident enough to teach an "Investment Principles" night class at the University of Nebraska-Omaha. The average age of his students was more than twice his own. During this time he also purchased a Sinclair gas station as a side investment but it was unsuccessful.
In 1954, Buffett accepted a job at Benjamin Graham 's partnership. His starting salary was $12,000 a year (about $ 136,000 today). There he worked closely with Walter Schloss. Graham was adamant that stock picks should provide a wide margin of safety after weighing the trade-off between their price and their intrinsic value. In 1956, Benjamin Graham retired and closed his partnership. At this time Buffett, who had amassed personal savings over $174,000 (about $ 1.95 million today), decided to return to Omaha, where he would quickly start a series of investment partnerships.
In 1957, Buffett operated three investment partnerships. By 1959, the total had grown to six partnerships. That year, Buffett met future partner Charlie Munger. In 1961, Buffett revealed that 35% of the partnerships' assets were invested in the Sanborn Map Company. He explained that Sanborn stock sold for only $45 per share in 1958, but the company's investment portfolio was worth $65 per share. This meant that Sanborn's map business was being valued at "minus $20". Buffett eventually purchased 23% of the company's outstanding shares as an activist investor, obtaining a seat for himself on the board of directors, and allied with other dissatisfied shareholders to control 44% of the shares. To avoid a proxy fight, the board offered to repurchase shares at fair value, paying with a portion of its investment portfolio. 77% of the outstanding shares were turned in. Buffett had reaped a 50 percent return on investment in just two years. |

A full factorial design may also be called a fully crossed design. Such an experiment allows the investigator to study the effect of each factor on the response variable, as well as the effects of interactions between factors on the response variable. For the vast majority of factorial experiments, each factor has only two levels. For example, with two factors each taking two levels, a factorial experiment would have four treatment combinations in total, and is usually called a 2×2 factorial design. In such a design, the interaction between the variables is often the most important. This applies even to scenarios where a main effect and an interaction are present. If the number of combinations in a full factorial design is too high to be logistically feasible, a fractional factorial design may be done, in which some of the possible combinations are omitted. Other terms for "treatment combinations" are often used, such as runs, points (viewing the combinations as vertices of a graph, and cells. |
synth_fc_1865_rep26 | Positive | History | Document search | Single | https://en.wikipedia.org/wiki/Cannon | 6 | Aircraft use
The first documented installation of a cannon on an aircraft was on the Voisin Canon in 1911, displayed at the Paris Exposition that year. By World War I, all of the major powers were experimenting with aircraft-mounted cannons; however, their low rate of fire and great size and weight precluded any of them from being anything other than experimental. The most successful (or least unsuccessful) was the SPAD 12 Ca.1 with a single 37 mm Puteaux mounted to fire between the cylinder banks and through the propeller boss of the aircraft's Hispano-Suiza 8C. The pilot (by necessity an ace) had to manually reload each round.
The first autocannon were developed during World War I as anti-aircraft guns, and one of these, the Coventry Ordnance Works " COW 37 mm gun ", was installed in an aircraft. However, the war ended before it could be given a field trial, and it never became standard equipment in a production aircraft. Later trials had it fixed at a steep angle upwards in both the Vickers Type 161 and the Westland C.O.W. Gun Fighter, an idea that would return later.
During this period autocannons became available and several fighters of the German Luftwaffe and the Imperial Japanese Navy Air Service were fitted with 20 mm cannons. They continued to be installed as an adjunct to machine guns rather than as a replacement, as the rate of fire was still too low and the complete installation too heavy. There was a some debate in the RAF as to whether the greater number of possible rounds being fired from a machine gun, or a smaller number of explosive rounds from a cannon was preferable. Improvements during the war in regards to rate of fire allowed the cannon to displace the machine gun almost entirely. The cannon was more effective against armour so they were increasingly used during the course of World War II, and newer fighters such as the Hawker Tempest usually carried two or four versus the six.50 Browning machine guns for US aircraft or eight to twelve M1919 Browning machine guns on earlier British aircraft. The Hispano-Suiza HS.404, Oerlikon 20 mm cannon, MG FF, and their numerous variants became among the most widely used autocannon in the war. Cannons, as with machine guns, were generally fixed to fire forwards (mounted in the wings, in the nose or fuselage, or in a pannier under either); or were mounted in gun turrets on heavier aircraft. Both the Germans and Japanese mounted cannons to fire upwards and forwards for use against heavy bombers, with the Germans calling guns so-installed Schräge Musik. This term derives from a German colloquialism for jazz music (schräg means "off-key").
Preceding the Vietnam War the high speeds aircraft were attaining led to a move to remove the cannon due to the mistaken belief that they would be useless in a dogfight, but combat experience during the Vietnam War showed conclusively that despite advances in missiles, there was still a need for them. Nearly all modern fighter aircraft are armed with an autocannon and they are also commonly found on ground-attack aircraft. One of the most powerful examples is the 30mm GAU-8/A Avenger Gatling-type rotary cannon, mounted exclusively on the Fairchild Republic A-10 Thunderbolt II. The Lockheed AC-130 gunship (a converted transport) can carry a 105 mm howitzer as well as a variety of autocannons ranging up to 40 mm. Both are used in the close air support role. |

Yuccas are widely grown as ornamental plants in gardens. Many species also bear edible parts, including fruits, seeds, flowers, flowering stems, and (more rarely) roots. References to yucca root as food often arise from confusion with the similarly pronounced, but botanically unrelated, yuca, also called cassava or manioc (Manihot esculenta). Roots of soaptree yucca (Yucca elata) are high in saponins and are used as a shampoo in Native American rituals. Dried yucca leaves and trunk fibers have a low ignition temperature, making the plant desirable for use in starting fires via friction. The stem (when dried) that sports the flowers is often used in conjunction with a sturdy piece of cedar for fire-making. In rural Appalachian areas, species such as Yucca filamentosa are referred to as "meat hangers". With their sharp-spined tips, the tough, fibrous leaves were used to puncture meat and knotted to form a loop with which to hang meat for salt curing or in smokehouses. The fibers can be used to make domestic items or for manufacturing cordage, be it sewing-thread or rope. Yucca extract is also used as a foaming agent in some beverages such as root beer and soda. Yucca powder and sap are derived from the logs of the plant; such extracts can be produced by mechanical squeezing and subsequent evaporation of the sap, and are widely used in food, cosmetics, and pharmaceuticals |

Rapid advances in automation technologies (e.g. fixed robots, collaborative and mobile robots, and exoskeletons) have the potential to improve work conditions but also to introduce workplace hazards in manufacturing workplaces. Despite the lack of occupational surveillance data on injuries associated specifically with robots, researchers from the US National Institute for Occupational Safety and Health (NIOSH) identified 61 robot-related deaths between 1992 and 2015 using keyword searches of the Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries research database (see info from Center for Occupational Robotics Research). Using data from the Bureau of Labor Statistics, NIOSH and its state partners have investigated 4 robot-related fatalities under the Fatality Assessment and Control Evaluation Program. In addition the Occupational Safety and Health Administration (OSHA) has investigated dozens of robot-related deaths and injuries, which can be reviewed at OSHA Accident Search page. Injuries and fatalities could increase over time because of the increasing number of collaborative and co-existing robots, powered exoskeletons, and autonomous vehicles into the work environment.
Safety standards are being developed by the Robotic Industries Association (RIA) in conjunction with the American National Standards Institute (ANSI). On October 5, 2017, OSHA, NIOSH and RIA signed an alliance to work together to enhance technical expertise, identify and help address potential workplace hazards associated with traditional industrial robots and the emerging technology of human-robot collaboration installations and systems, and help identify needed research to reduce workplace hazards. On October 16 NIOSH launched the Center for Occupational Robotics Research to "provide scientific leadership to guide the development and use of occupational robots that enhance worker safety, health, and wellbeing." So far, the research needs identified by NIOSH and its partners include: tracking and preventing injuries and fatalities, intervention and dissemination strategies to promote safe machine control and maintenance procedures, and on translating effective evidence-based interventions into workplace practice. |

The Ethiopian Highlands began to rise 75 million years ago, as magma from the Earth's mantle uplifted a broad dome of the ancient rocks of the Arabian-Nubian Shield. The opening of the Great Rift Valley split the dome of the Ethiopian Highlands into three parts; the mountains of the southern Arabian Peninsula are geologically part of the ancient Ethiopian Highlands, separated by the rifting which created the Red Sea and Gulf of Aden and separated Africa from Arabia.
Around 30 million years ago, a flood basalt plateau began to form, piling layers upon layers of voluminous fissure-fed basaltic lava flows. Most of the flows were tholeiitic, save for a thin layer of alkali basalts and minor amounts of felsic (high-silica) volcanic rocks, such as rhyolite. In the waning stages of the flood basalt episode, large explosive caldera -forming eruptions also occurred.
The Ethiopian Highlands were eventually bisected by the Great Rift Valley as the African continental crust pulled apart. This rifting gave rise to large alkaline basalt shield volcanoes beginning about 30–31 million years ago.
The northern Ethiopian Highlands contain four discernible planation surfaces, the oldest one being formed not later than in the Ordovician Period. The youngest surface formed in the Cenozoic, being partly covered by the Ethiopia-Yemen Continental Flood Basalts. Contrary to what has been suggested for much of Africa, planation surfaces in northern Ethiopia do not appear to be pediplains nor etchplains. |

There were labor shortages during World War I. Ford Motor Co. doubled wages to reduce turnover. After 1925, unemployment gradually began to rise.
The 1930s saw the Great Depression impact unemployment across the globe. In Germany and the United States, the unemployment rate reached about 25% in 1932.
In some towns and cities in the northeast of England, unemployment reached as high as 70%; the national unemployment level peaked at more than 22% in 1932. Unemployment in Canada reached 27% at the depth of the Depression in 1933. In 1929, the U.S. unemployment rate averaged 3%.
In the US, the Works Progress Administration (1935–43) was the largest make-work program. It hired men (and some women) off the relief roles ("dole") typically for unskilled labor. During the New Deal, over three million unemployed young men were taken out of their homes and placed for six months into more than 2600 work camps managed by the Civilian Conservation Corps.
Unemployment in the United Kingdom fell later in the 1930s as the Depression eased, and it remained low (in single figures) after World War II.
Fredrick Mills found that in the US, 51% of the decline in work hours was due to the fall in production and 49% was from increased productivity.
By 1972, unemployment in the United Kingdom had crept back up above 1,000,000, and it was even higher by the end of the decade, with inflation also being high. Although the monetarist economic policies of Margaret Thatcher 's Conservative government saw inflation reduced after 1979, unemployment soared in the early 1980s and in 1982, it exceeded 3,000,000, a level that had not been seen for some 50 years. That represented one in eight of the workforce, with unemployment exceeding 20% in some places that had relied on declining industries such as coal mining.
However, it was a time of high unemployment in all other major industrialised nations as well. By the spring of 1983, unemployment had risen by 6% in the previous 12 months, compared to 10% in Japan, 23% in the US, and 34% in West Germany (seven years before Reunification).
Unemployment in the United Kingdom remained above 3,000,000 until the spring of 1987, when the economy enjoyed a boom. By the end of 1989, unemployment had fallen to 1,600,000. However, inflation had reached 7.8%, and the following year, it reached a nine-year high of 9.5%; leading to increased interest rates.
Another recession occurred from 1990 to 1992. Unemployment began to increase, and by the end of 1992, nearly 3,000,000 in the United Kingdom were unemployed, a number that was soon lowered by a strong economic recovery. With inflation down to 1.6% by 1993, unemployment then began to fall rapidly and stood at 1,800,000 by early 1997. |

Several previous classifications have been used, including Rappaport 1956, Lennert/Kiel 1974, BNLI, Working formulation (1982), and REAL (1994).
The Working Formulation of 1982 was a classification of non-Hodgkin lymphoma. It excluded the Hodgkin lymphomas and divided the remaining lymphomas into four grades (low, intermediate, high, and miscellaneous) related to prognosis, with some further subdivisions based on the size and shape of affected cells. This purely histological classification included no information about cell surface markers or genetics and made no distinction between T-cell lymphomas and B-cell lymphomas. It was widely accepted at the time of its publication but by 2004 was obsolete.
In 1994, the Revised European-American Lymphoma (REAL) classification applied immunophenotypic and genetic features in identifying distinct clinicopathologic entities among all the lymphomas except Hodgkin lymphoma. For coding purposes, the ICD-O (codes 9590–9999) and ICD-10 (codes C81-C96) are available. |

The atoll is composed of three islets and a reef surrounding a lagoon. The nearest inhabited island is Utirik Atoll in the Marshall Islands, located 592 miles to the southeast. The island may have been found by prehistoric Austronesian mariners before its first recorded discovery by Álvaro de Mendaña de Neira in 1568. Ships continued to visit the area in the following centuries until it was claimed by the United States in 1899. The island had little development until 1935, when Pan American Airways constructed an airfield and hotel as a waypoint for trans-Pacific flying boats. Japan seized the island at the opening of the Pacific Theatre of World War II in December 1941, and it remained under Japanese occupation until the end of the war in September 1945. After trans-Pacific layovers by Pan American Airways ceased in 1972 due to their use of Boeing 747s, administration was taken over by the United States Air Force, which used the atoll as a processing location for Vietnamese refugees during Operation New Life in 1975. Wake Island, which is claimed by the Marshall Islands, is governed by the United States as an unorganized and unincorporated territory and comprises part of the United States Minor Outlying Islands. It is administered by the United States Air Force under an agreement with the Department of the Interior. The island has no permanent inhabitants, but approximately 100 people live there at any given time. The natural areas of Wake are mix of tropical trees, scrub, and grasses that have adapted to the limited rainfall. Thousands of hermit crabs and rats live on Wake, and in the past there were also feral cats which had been there to help control the rat population, which at one time was estimated at 2 million. The Wake Island rail, a small flightless bird, once lived on the atoll but went extinct during World War II. Many species of seabird also visit Wake, although the thick vegetation has caused most birds to nest on a designated bird sanctuary on Wilkes Island. The submerged and emergent lands at Wake Island comprise a unit of the Pacific Remote Islands Marine National Monument. |

synth_fc_1520_rep18 | No function call | Geography | Feature search | Single | https://en.wikipedia.org/wiki/Smuggling | 4 | History
Smuggling has a long and controversial history, probably dating back to the first time at which duties were imposed in any form, or any attempt was made to prohibit a form of traffic. Smuggling is often associated with efforts by authorities to prevent the importation of certain contraband items or non-taxed goods; however, there has also been smuggling based on illegally exporting goods. In England smuggling first became a recognised problem in the 13th century, following the creation of a national customs collection system by Edward I in 1275. Medieval smuggling tended to focus on the export of highly taxed export goods — notably wool and hides. Merchants also, however, sometimes smuggled other goods to circumvent prohibitions or embargoes on particular trades. Grain, for instance, was usually prohibited from export, unless prices were low, because of fears that grain exports would raise the price of food in England and thus cause food shortages and civil unrest. Following the loss of Gascony to the French in 1453, imports of wine were also sometimes embargoed during wars to try to deprive the French of the revenues that could be earned from their main export.
Most studies of historical smuggling have been based on official sources — such as court records, or the letters of Revenue Officers. A senior academic of the University of Bristol states that they only detail the activities of those dumb enough to get caught. This has led him and others, such as Prof. H. V. Bowen of the University of Swansea to use commercial records to reconstruct smuggling businesses. Jones' study focuses on smuggling in Bristol in the mid-16th century, arguing that the illicit export of goods like grain and leather represented a significant part of the city's business, with many members of the civic elite engaging in it, whether by disguised/hidden transport or mis-description of goods. Grain smuggling by members of the civic elite, often working closely with corrupt customs officers, has also been shown to have been prevalent in East Anglia during the later 16th century.
In England wool was smuggled to the continent in the 17th century, under the pressure of high excise taxes. In 1724 Daniel Defoe wrote of Lymington, Hampshire, on the south coast of England
I do not find they have any foreign commerce, except it be what we call smuggling and roguing; which I may say, is the reigning commerce of all this part of the English coast, from the mouth of the Thames to the Land's End in Cornwall.
The high rates of duty levied on tea and also wine and spirits, and other luxury goods coming in from mainland Europe at this time made the clandestine import of such goods and the evasion of the duty a highly profitable venture for impoverished fishermen and seafarers. In certain parts of the country such as the Romney Marsh, East Kent, Cornwall and East Cleveland, the smuggling industry was for many communities more economically significant than legal activities such as farming and fishing. The principal reason for the high duty was the need for the government to finance a number of extremely expensive wars with France and the United States.
Before the era of drug smuggling and human trafficking, smuggling had acquired a kind of nostalgic romanticism, in the vein of Robert Louis Stevenson 's Kidnapped:
Few places on the British coast did not claim to be the haunts of wreckers or mooncussers. The thievery was boasted about and romanticized until it seemed a kind of heroism. It did not have any taint of criminality and the whole of the south coast had pockets vying with one another over whose smugglers were the darkest or most daring. The Smugglers Inn was one of the commonest names for a bar on the coast.
In North America, smuggling in colonial times was a reaction to the heavy taxes and regulations imposed by mercantilist trade policies. After American independence in 1783, smuggling developed at the edges of the United States at places like Passamaquoddy Bay, St. Mary's in Georgia, Lake Champlain, and Louisiana. During Thomas Jefferson 's embargo of 1807-1809, these same places became the primary places where goods were smuggled out of the nation in defiance of the law. Like Britain, a gradual liberalization of trade laws as part of the free trade movement meant less smuggling. in 1907 President Theodore Roosevelt tried to cut down on smuggling by establishing the Roosevelt Reservation along the United States-Mexico Border. Smuggling revived in the 1920s during Prohibition, and drug smuggling became a major problem after 1970. In the 1990s, when economic sanctions were imposed on Serbia, a large percent of the population lived off smuggling petrol and consumer goods from neighboring countries. The state unofficially allowed this to continue or otherwise the entire economy would have collapsed.
In modern times, as many first-world countries have struggled to contain a rising influx of immigrants, the smuggling of people across national borders has become a lucrative extra-legal activity, as well as the extremely dark side, people-trafficking, especially of women who may be enslaved typically as prostitutes. |

The longitude convention for Mercury puts the zero of longitude at one of the two hottest points on the surface, as described above. However, when this area was first visited, by Mariner 10, this zero meridian was in darkness, so it was impossible to select a feature on the surface to define the exact position of the meridian. Therefore, a small crater further west was chosen, called Hun Kal, which provides the exact reference point for measuring longitude. The center of Hun Kal defines the 20° west meridian. A 1970 International Astronomical Union resolution suggests that longitudes be measured positively in the westerly direction on Mercury. The two hottest places on the equator are therefore at longitudes 0° W and 180° W, and the coolest points on the equator are at longitudes 90° W and 270° W. However, the MESSENGER project uses an east-positive convention. |

In standard cosmology, there are three components of the universe: matter, radiation, and dark energy. This matter is anything whose energy density scales with the inverse cube of the scale factor, i.e., ρ ∝ a, while radiation is anything whose energy density scales to the inverse fourth power of the scale factor (ρ ∝ a). This can be understood intuitively: for an ordinary particle in a cube-shaped box, doubling the length of an edge of the box decreases the density (and hence energy density) by a factor of eight (2). For radiation, the decrease in energy density is greater, because an increase in spatial distance also causes a redshift.
The final component is dark energy: it is an intrinsic property of space and has a constant energy density, regardless of the dimensions of the volume under consideration (ρ ∝ a). Thus, unlike ordinary matter, it is not diluted by the expansion of space. |

The earliest roller skates known are from 18th-century Europe. These skates were used in theater and musical performances, possibly to simulate ice skating onstage. Early roller skating was done in a straight line because turning or curving was very difficult with the primitive skate designs of the time. Limited to an occasional performance prop at the time, roller skating would not see widespread use until the 1840s.
Waitresses in an 1840s beer hall in Berlin used roller skates to serve customers. Ballet and opera of the late 1840s, such as Le prophète, featured roller skating. This helped to make roller skating popular for the first time, in 1850s Europe. Technological improvements improved on the design as well, such as rubber wheels in 1859 and four-wheeled turning skates in 1863. The popularity of roller skating has fluctuated greatly since then; it is typically called a "craze" at its high points.
Roller skating boomed in popularity from 1880 to 1910; roller skates were mass produced and skating in rinks became popular with the general public in Europe, North and South America, and Australia. Specialized types of roller skating appeared in this period, such as figure skating and speed skating.
After a decline in popularity, roller skating became widespread again in the 1930s to the 1950s. This era is known as the Golden Age of Roller Skating. Many skating rinks offering electric organ music were built throughout the United States in this period.
In the 1970s, roller disco became widespread. This style of skating originated with disco music predominantly among Black and gay skaters. During the late 1980s and the 1990s, outdoor and indoor inline skating (with " rollerblades ") became popular. Roller skating declined in popularity in the early 21st century, but became more popular again during the COVID pandemic.
Roller skating has long been tied to Black American social movements, immigrant communities, and the LGBT community, particularly for women in roller derby. As a hobby it is perceived as whimsical and is widely accessible to many people. |

At sixteen years of age, Constantijn sent Huygens to study law and mathematics at Leiden University, where he studied from May 1645 to March 1647. Frans van Schooten was an academic at Leiden from 1646, and became a private tutor to Huygens and his elder brother, Constantijn Jr., replacing Stampioen on the advice of Descartes. Van Schooten brought Huygens's mathematical education up to date, introducing him to the work of Viète, Descartes, and Fermat.
After two years, starting in March 1647, Huygens continued his studies at the newly founded Orange College, in Breda, where his father was a curator. Constantijn Huygens was closely involved in the new College, which lasted only to 1669; the rector was André Rivet. Christiaan Huygens lived at the home of the jurist Johann Henryk Dauber while attending college, and had mathematics classes with the English lecturer John Pell. His time in Breda ended around the time when his brother Lodewijk, who was enrolled at the school, duelled with another student. Huygens left Breda after completing his studies in August 1649 and had a stint as a diplomat on a mission with Henry, Duke of Nassau. It took him to Bentheim, then Flensburg. He took off for Denmark, visited Copenhagen and Helsingør, and hoped to cross the Øresund to visit Descartes in Stockholm. It was not to be.
Although his father Constantijn had wished his son Christiaan to be a diplomat, circumstances kept him from becoming so. The First Stadtholderless Period that began in 1650 meant that the House of Orange was no longer in power, removing Constantijn's influence. Further, he realized that his son had no interest in such a career. |

Susannah Melvoin recalled how, around the time of Sign o' the Times, "Wendy and Lisa and I lived together and we would have stay at our place. We became really close. He got to be in a family of three women, and we got to have our Prince. Not many people had that kind of relationship with him."
In 1990, he saw 16-year-old dancer Mayte García standing outside his tour bus and referred to her as his "future wife" when pointing her out to bandmate Rosie Gaines. García began working as one of his backup singers and dancers after graduating from high school. They were married on February 14, 1996, when he was 37 and she was 22. According to García, she and Prince had a son named Amiir (born October 16, 1996), who died a week after being born due to Pfeiffer syndrome. Attempts by publications to independently verify the child's name, birth, and cause of death proved difficult due to Prince's focus on privacy. The distress of losing a child and García's subsequent miscarriage took a toll on the marriage, and the couple divorced in 2000.
Prince married Manuela Testolini, a Canadian businesswoman of Italian and Egyptian descent, in a private ceremony in 2001; she hails from Toronto, which led the couple to live there part-time. They separated in 2005 and filed for divorce in May 2006, which was finalized in October 2007. |

The Settlement movement and its leaders such as Jane Addams, Julia Lathrop, and Florence Kelley were instrumental in crafting the alternative, feminine inspired, model of public administration. This settlement model of public administration, had two interrelated components – municipal housekeeping and industrial citizenship. Municipal housekeeping called for cities to be run like a caring home, the city should be conceived as an extension of the home where families could be safe and children cared for. Clean streets, clean water, playgrounds, educational curricular reform, and juvenile courts, are examples of reforms associated with this movement. Industrial citizenship focused on the problems and risks of labor force participation in a laissez-faire, newly industrialized economy. Reforms that mitigated workplace problems such as child labor, unsanitary workplaces, excessive work schedules, risks of industrial accidents, and old age poverty were the focus of these efforts. Organized settlement women's reform efforts led to workplace safety laws and inspections. Settlement reformers went on to serve as local, state, and federal administrators. Jane Addams was a garbage inspector, Florence Kelley served as the chief factory inspector for the State of Illinois, Julia Lathrop was the first director of the Women's Bureau and Francis Perkins was Secretary of Labor during the F.

Overall, transgender and gender diverse individuals face multiple barriers to achieving family planning goals. This community experiences lack of access to reproductive health care settings where they feel accepted, safe, and understood; reproduction help; pregnancy care; and contraception. A barrier that gets in the way of becoming parents is the cost involved with fertility preservation options. For example, the use of sperm cryopreservation in the United States is less than 5% while countries such as the Netherlands, Australia and Israel have higher rates; this may be the result of challenges navigating health insurance coverage. According to a study, in the United States the national median initial bank fee and annual price of storage are $350 and $385 respectively. For those looking for egg preservation, a study calculated that the median total cost (which includes egg freezing, egg thawing, and annual preservation fee) in United States was around $7,444, and the cumulative costs for one live birth of US$11,704 for an individual in the age groups ≤ 35 years. Other common concerns that arise when seeking pregnancy include having to stop or delay of hormonal therapy, worsening of gender dysphoria with treatment related to pregnancy.
Interventions used to facilitate gender transition such as hormone therapy and gender affirming surgeries (e.g., genital surgery, and chest surgery) can temporarily or permanently impact the chance of becoming pregnant. The World Professional Organization for Transgender Health (WPATH) and American Society for Reproductive Medicine (ASRMA) recommend offering counseling on the impact on family planning and transitioning to all transgender individuals Even though many transgender and gender-nonbinary youth express desire to receive fertility counseling and recommendations from professional organization, studies indicate that only a small portion have these conversations with their health care team. Health care professionals attribute lack of knowledge of reproductive health in this community, knowledge limitation due to lack of data on long term effects of hormonal intervention to the inconsistency in discussion around family building
Studies have shown that transgender men can still become pregnant even in the absence of menstruation caused by gendered affirming therapy in the form of testosterone. Inconsistent hormonal therapy such as missed doses, incomplete dosing, or switching therapy regimen, mostly due to barriers noted earlier, may also lead to breakthrough ovulation which can contribute to increase chances of unintended pregnant, highlighting the need of contraception on transgender men (who have conserved reproductive organs) on testosterone if pregnancy is not desired. Furthermore, testosterone can cause abnormal vaginal development in female fetuses (especially in the first trimester of pregnancy), becoming a concern for transgender men who conceived while on hormone therapy. Moreover, condoms are one of the most common contraceptive methods in transgender men, while another subset report no contraception use which can lead to unintended pregnancies. Some challenges to adopting a form of family planning method among this population varies depending on the method. For instance, fear of prevention of masculinization with use of estrogen-based contraceptives, and gender dysphoria with the use of contraceptive devises inside cervical/pelvic cavity. Additionally, negative experiences in the health care system related to gender identity, and denial of health care based on gender identity makes it difficult for this community to access health care and family planning resources. |

Vitamins and minerals are required for normal metabolism; and what the body cannot manufacture itself must come from external sources. Vitamins come from several sources including fresh fruit and vegetables (Vitamin C), carrots, liver (Vitamin A), cereal bran, bread, liver (B vitamins), fish liver oil (Vitamin D) and fresh green vegetables (Vitamin K). Many minerals are also essential in small quantities including iron, calcium, magnesium, sodium chloride and sulfur; and in very small quantities copper, zinc and selenium. The micronutrients, minerals, and vitamins in fruit and vegetables may be destroyed or eluted by cooking. Vitamin C is especially prone to oxidation during cooking and may be completely destroyed by protracted cooking. The bioavailability of some vitamins such as thiamin, vitamin B6, niacin, folate, and carotenoids are increased with cooking by being freed from the food microstructure. Blanching or steaming vegetables is a way of minimizing vitamin and mineral loss in cooking. |

A series of measures taken by the authorities of the city throughout the 1990s resulted in the improvement of air quality; the appearance of smog (or nefos as the Athenians used to call it) has become less common.
Measures taken by the Greek authorities throughout the 1990s have improved the quality of air over the Attica Basin. Nevertheless, air pollution still remains an issue for Athens, particularly during the hottest summer days. In late June 2007, the Attica region experienced a number of brush fires, including a blaze that burned a significant portion of a large forested national park in Mount Parnitha, considered critical to maintaining a better air quality in Athens all year round. Damage to the park has led to worries over a stalling in the improvement of air quality in the city.

Some 60% of Iran's economy is centrally planned. Iran's economy is characterized by its hydrocarbon, agricultural, and service sectors, in addition to manufacturing and financial services, with over 40 industries directly involved in the Tehran Stock Exchange. The stock exchange has been one of the best performing exchanges in the world over the past decade. With 10% of the world's proven oil reserves and 15% of its gas reserves, Iran is considered an "energy superpower". A unique feature of Iran's economy is the presence of large religious foundations called bonyads, whose combined budgets represent more than 30 percent of central government spending. Price controls and subsidies, particularly on food and energy, are heavily prominent in the economy. Contraband, administrative controls, widespread corruption, and other restrictive factors undermine private sector-led growth. The government's 20-year vision, involves market-based reforms reflected in the government's, with a five year development plan focusing on "a resilient economy" and "progress in science and technology". Most of the country's exports are oil and gas, accounting for a majority of government revenue in 2010. However in March 2022, the Iranian parliament under the then new president Ebrahim Raisi decided to eliminate a major subsidy for importing food, medicines and animal feed, valued at $15 billion in FY2021. Also in March 2022, 20 billion tons of basic goods exports from Russia including vegetable oil, wheat, barley and corn were agreed. Iran's educated population, high human development, constrained economy and insufficient foreign and domestic investment prompted an increasing number of Iranians to seek overseas employment, resulting in a significant "brain drain". However, in 2015, Iran and the P5+1 reached a deal on the nuclear program which removed most international sanctions. Consequently, for a short period, the tourism industry was significantly improved and the inflation of the country was decreased though US withdrawal from the JCPOA in 2018 hindered the growth of the economy again and increased inflation.

An investor may bear a risk of loss of some or all of their capital invested. Investment differs from arbitrage, in which profit is generated without investing capital or bearing risk.
Savings bear the (normally remote) risk that the financial provider may default.
Foreign currency savings also bear foreign exchange risk: if the currency of a savings account differs from the account holder's home currency, then there is the risk that the exchange rate between the two currencies will move unfavourably so that the value of the savings account decreases, measured in the account holder's home currency.
Even investing in tangible assets like property has its risk. And similar to most risks, property buyers can seek to mitigate any potential risk by taking out mortgage and by borrowing at a lower loan to security ratio.
In contrast with savings, investments tend to carry more risk, in the form of both a wider variety of risk factors and a greater level of uncertainty.
Industry to industry volatility is more or less of a risk depending. In biotechnology, for example, investors look for big profits on companies that have small market capitalizations but can be worth hundreds of millions quite quickly.

Since inception in the US in 1941, television commercials have become one of the most effective, persuasive, and popular methods of selling products of many sorts, especially consumer goods. During the 1940s and into the 1950s, programs were hosted by single advertisers. This, in turn, gave great creative control to the advertisers over the content of the show. Perhaps due to the quiz show scandals in the 1950s, networks shifted to the magazine concept, introducing advertising breaks with other advertisers.
U.S. advertising rates are determined primarily by Nielsen ratings. The time of the day and popularity of the channel determine how much a TV commercial can cost. For example, it can cost approximately $750,000 for a 30-second block of commercial time during the highly popular singing competition American Idol, while the same amount of time for the Super Bowl can cost several million dollars. Conversely, lesser-viewed time slots, such as early mornings and weekday afternoons, are often sold in bulk to producers of infomercials at far lower rates. In recent years, paid programs or infomercials have become common, usually in lengths of 30 minutes or one hour. Some drug companies and other businesses have even created "news" items for broadcast, known in the industry as video news releases, paying program directors to use them.
Some television programs also deliberately place products into their shows as advertisements, a practice started in feature films and known as product placement. For example, a character could be drinking a certain kind of soda, going to a particular chain restaurant, or driving a certain make of car. (This is sometimes very subtle, with shows having vehicles provided by manufacturers for low cost in exchange as a product placement). Sometimes, a specific brand or trade mark, or music from a certain artist or group, is used. (This excludes guest appearances by artists who perform on the show.) |

Malaysia is a federation of 13 states and three federal territories. These are divided between two regions, with 11 states and two federal territories on Peninsular Malaysia and the other two states and one federal territory in East Malaysia. Each state is divided into districts, which are then divided into mukim. In Sabah and Sarawak districts are grouped into divisions.
Governance of the states is divided between the federal and the state governments, with different powers reserved for each, and the Federal government has direct administration of the federal territories. Each state has a unicameral State Legislative Assembly whose members are elected from single-member constituencies. State governments are led by Chief Ministers, who are state assembly members from the majority party in the assembly. In each of the states with a hereditary ruler, the Chief Minister is normally required to be a Malay, appointed by the ruler upon the recommendation of the Prime Minister. Except for state elections in Sarawak, by convention state elections are held concurrently with the federal election.
Lower-level administration is carried out by local authorities, which include city councils, district councils, and municipal councils, although autonomous statutory bodies can be created by the federal and state governments to deal with certain tasks. The federal constitution puts local authorities outside of the federal territories under the exclusive jurisdictions of the state government, although in practice the federal government has intervened in the affairs of state local governments. There are 154 local authorities, consisting of 14 city councils, 38 municipal councils and 97 district councils.
The 13 states are based on historical Malay kingdoms, and 9 of the 11 Peninsular states, known as the Malay states, retain their royal families. The King is elected by and from the nine rulers to serve a five-year term. This King appoints governors serving a four-year term for the states without monarchies, after consultations with the chief minister of that state. Each state has its own written constitution. Sabah and Sarawak have considerably more autonomy than the other states, most notably having separate immigration policies and controls, and a unique residency status. Federal intervention in state affairs, lack of development, and disputes over oil royalties have occasionally led to statements about secession from leaders in several states such as Penang, Johor, Kelantan, Sabah and Sarawak, although these have not been followed up and no serious independence movements exist.

"Market liquidity" describes how easily an item can be traded for another item, or into the common currency within an economy. Money is the most liquid asset because it is universally recognized and accepted as a common currency. In this way, money gives consumers the freedom to trade goods and services easily without having to barter.
Liquid financial instruments are easily tradable and have low transaction costs. There should be no (or minimal) spread between the prices to buy and sell the instrument being used as money. |

Reserves are held in one or more reserve currencies, nowadays mostly the United States dollar and to a lesser extent the euro. Foreign exchange reserves assets can comprise banknotes, bank deposits, and government securities of the reserve currency, such as bonds and treasury bills. Some countries hold a part of their reserves in gold, and special drawing rights are also considered reserve assets. Often, for convenience, the cash or securities are retained by the central bank of the reserve or other currency and the "holdings" of the foreign country are tagged or otherwise identified as belonging to the other country without them actually leaving the vault of that central bank. From time to time they may be physically moved to the home or another country. Normally, interest is not paid on foreign cash reserves, nor on gold holdings, but the central bank usually earns interest on government securities. The central bank may, however, profit from a depreciation of the foreign currency or incur a loss on its appreciation. The central bank also incurs opportunity costs from holding the reserve assets and from their storage, security costs, etc. |

The Exceptional Access Framework was created in 2003 when John B. Taylor was Under Secretary of the US Treasury for International Affairs. The new Framework became fully operational in February 2003 and it was applied in the subsequent decisions on Argentina and Brazil. Its purpose was to place some sensible rules and limits on the way the IMF makes loans to support governments with debt problem—especially in emerging markets—and thereby move away from the bailout mentality of the 1990s. Such a reform was essential for ending the crisis atmosphere that then existed in emerging markets. The reform was closely related to and put in place nearly simultaneously with the actions of several emerging market countries to place collective action clauses in their bond contracts.
In 2010, the framework was abandoned so the IMF could make loans to Greece in an unsustainable and political situation.
The topic of sovereign debt restructuring was taken up by IMF staff in April 2013 for the first time since 2005, in a report entitled "Sovereign Debt Restructuring: Recent Developments and Implications for the Fund's Legal and Policy Framework". The paper, which was discussed by the board on 20 May, summarised the recent experiences in Greece, St Kitts and Nevis, Belize, and Jamaica. An explanatory interview with deputy director Hugh Bredenkamp was published a few days later, as was a deconstruction by Matina Stevis of The Wall Street Journal.
The staff was directed to formulate an updated policy, which was accomplished on 22 May 2014 with a report entitled "The Fund's Lending Framework and Sovereign Debt: Preliminary Considerations", and taken up by the executive board on 13 June. The staff proposed that "in circumstances where a (Sovereign) member has lost market access and debt is considered sustainable... the IMF would be able to provide Exceptional Access on the basis of a debt operation that involves an extension of maturities", which was labeled a "reprofiling operation". These reprofiling operations would "generally be less costly to the debtor and creditors—and thus to the system overall—relative to either an upfront debt reduction operation or a bail-out that is followed by debt reduction... (and) would be envisaged only when both (a) a member has lost market access and (b) debt is assessed to be sustainable, but not with high probability... Creditors will only agree if they understand that such an amendment is necessary to avoid a worse outcome: namely, a default and/or an operation involving debt reduction... Collective action clauses, which now exist in most—but not all—bonds would be relied upon to address collective action problems." |

In 2021–2022, most countries experienced a considerable increase in inflation, peaking in 2022 and declining in 2023. The causes are believed to be a mixture of demand and supply shocks, whereas inflation expectations generally seem to remain anchored (as per May 2023). Possible causes on the demand side include expansionary fiscal and monetary policy in the wake of the global COVID-19 pandemic, whereas supply shocks include supply chain problems also caused by the pandemic and exacerbated by energy price rises following the Russian invasion of Ukraine in 2022.
The term sellers' inflation was coined during this period to describe the effect of corporate profits as a possible cause of inflation: Price inelasticity can contribute to inflation when firms consolidate, tending to support monopoly or monopsony conditions anywhere along the supply chain for goods or services. When this occurs, firms can provide greater shareholder value by taking a larger proportion of profits than by investing in providing greater volumes of their outputs. Shortly after initial energy price shocks caused by the Russian invasion of Ukraine had subsided, oil companies found that supply chain constrictions, already exacerbated by the ongoing global pandemic, supported price inelasticity, i.e., they began lowering prices to match the price of oil when it fell much more slowly than they had increased their prices when costs rose.
The quantity theory of money has long been popular with libertarian-conservative critics of the Federal Reserve. During the COVID pandemic and its immediate aftermath, the M2 money supply increased at the fastest rate in decades, leading some to link the growth to the 2021-2023 inflation surge. Fed chairman Jerome Powell said in December 2021 that the once-strong link between the money supply and inflation "ended about 40 years ago," due to financial innovations and deregulation. Powell's immediate predecessors, Ben Bernanke and Alan Greenspan, had previously concurred with this position. The broadest measure of money supply, M3, increased about 45% from 2010 through 2015, far faster than GDP growth, yet the inflation rate declined during that period — the opposite of what monetarism would have predicted. A lower velocity of money than was historically the case was also cited for a diminished effect of growth in the money supply on inflation. |

Later in the 20th century several British pathologists, Mikey Rochman, Francis Camps, Sydney Smith and Keith Simpson pioneered new forensic science methods. Alec Jeffreys pioneered the use of DNA profiling in forensic science in 1984. He realized the scope of DNA fingerprinting, which uses variations in the genetic code to identify individuals. The method has since become important in forensic science to assist police detective work, and it has also proved useful in resolving paternity and immigration disputes. DNA fingerprinting was first used as a police forensic test to identify the rapist and killer of two teenagers, Lynda Mann and Dawn Ashworth, who were both murdered in Narborough, Leicestershire, in 1983 and 1986 respectively. Colin Pitchfork was identified and convicted of murder after samples taken from him matched semen samples taken from the two dead girls.
Forensic science has been fostered by a number of national and international forensic science learned bodies including the American Academy of Forensic Sciences (founded 1948), publishers of the Journal of Forensic Sciences; the Canadian Society of Forensic Science (founded 1953), publishers of the Journal of the Canadian Society of Forensic Science; the Chartered Society of Forensic Sciences, (founded 1959), then known as the Forensic Science Society, publisher of Science & Justice; the British Academy of Forensic Sciences (founded 1960), publishers of Medicine, Science and the Law; the Australian Academy of Forensic Sciences (founded 1967), publishers of the Australian Journal of Forensic Sciences; and the European Network of Forensic Science Institutes (founded 1995). |

In 1970, after an explosion aboard Apollo 13 aborted its lunar landing, Armstrong was part of Edgar Cortright 's investigation of the mission. He produced a detailed chronology of the flight. He determined that a 28-volt thermostat switch in an oxygen tank, which was supposed to have been replaced with a 65-volt version, led to the explosion. Cortright's report recommended the entire tank be redesigned at a cost of $40 million. Many NASA managers, including Armstrong, opposed the recommendation, since only the thermostat switch had caused the problem. They lost the argument, and the tanks were redesigned.
In 1986, President Ronald Reagan asked Armstrong to join the Rogers Commission investigating the Space Shuttle Challenger disaster. Armstrong was made vice chairman of the commission and held private interviews with contacts he had developed over the years to help determine the cause of the disaster. He helped limit the committee's recommendations to nine, believing that if there were too many, NASA would not act on them.
Armstrong was appointed to a fourteen-member commission by President Reagan to develop a plan for American civilian spaceflight in the 21st century. The commission was chaired by former NASA administrator Dr. Thomas O. Paine, with whom Armstrong had worked during the Apollo program. The group published a book titled Pioneering the Space Frontier: The Report on the National Commission on Space, recommending a permanent lunar base by 2006, and sending people to Mars by 2015. The recommendations were largely ignored, overshadowed by the Challenger disaster.

synth_fc_2962_rep19 | Positive | School | Database search | Multi | https://en.wikipedia.org/wiki/Social_group | 15 | Dispersal and transformation
Two or more people in interacting situations will over time develop stable territorial relationships. As described above, these may or may not develop into groups. But stable groups can also break up in to several sets of territorial relationships. There are numerous reasons for stable groups to "malfunction" or to disperse, but essentially this is because of loss of compliance with one or more elements of the definition of group provided by Sherif. The two most common causes of a malfunctioning group are the addition of too many individuals, and the failure of the leader to enforce a common purpose, though malfunctions may occur due to a failure of any of the other elements (i.e., confusions status or of norms).
In a society, there is a need for more people to participate in cooperative endeavors than can be accommodated by a few separate groups. The military has been the best example as to how this is done in its hierarchical array of squads, platoons, companies, battalions, regiments, and divisions. Private companies, corporations, government agencies, clubs, and so on have all developed comparable (if less formal and standardized) systems when the number of members or employees exceeds the number that can be accommodated in an effective group. Not all larger social structures require the cohesion that may be found in the small group. Consider the neighborhood, the country club, or the megachurch, which are basically territorial organizations who support large social purposes. Any such large organizations may need only islands of cohesive leadership.
For a functioning group to attempt to add new members in a casual way is a certain prescription for failure, loss of efficiency, or disorganization. The number of functioning members in a group can be reasonably flexible between five and ten, and a long-standing cohesive group may be able to tolerate a few hangers on. The key concept is that the value and success of a group is obtained by each member maintaining a distinct, functioning identity in the minds of each of the members. The cognitive limit to this span of attention in individuals is often set at seven. Rapid shifting of attention can push the limit to about ten. After ten, subgroups will inevitably start to form with the attendant loss of purpose, dominance-order, and individuality, with confusion of roles and rules. The standard classroom with twenty to forty pupils and one teacher offers a rueful example of one supposed leader juggling a number of subgroups.
Weakening of the common purpose once a group is well established can be attributed to: adding new members; unsettled conflicts of identities (i.e., territorial problems in individuals); weakening of a settled dominance-order; and weakening or failure of the leader to tend to the group. The actual loss of a leader is frequently fatal to a group, unless there was lengthy preparation for the transition. The loss of the leader tends to dissolve all dominance relationships, as well as weakening dedication to common purpose, differentiation of roles, and maintenance of norms. The most common symptoms of a troubled group are loss of efficiency, diminished participation, or weakening of purpose, as well as an increase in verbal aggression. Often, if a strong common purpose is still present, a simple reorganization with a new leader and a few new members will be sufficient to re-establish the group, which is somewhat easier than forming an entirely new group. This is the most common factor. |

There have been many dozens of derivations of the Lorentz transformations since Einstein's original work in 1905, each with its particular focus. Although Einstein's derivation was based on the invariance of the speed of light, there are other physical principles that may serve as starting points. Ultimately, these alternative starting points can be considered different expressions of the underlying principle of locality, which states that the influence that one particle exerts on another can not be transmitted instantaneously.
The derivation given here and illustrated in Fig. 3-5 is based on one presented by Bais and makes use of previous results from the Relativistic Composition of Velocities, Time Dilation, and Length Contraction sections. Event P has coordinates (w, x) in the black "rest system" and coordinates (w ′, x ′) in the red frame that is moving with velocity parameter β = v / c. To determine w ′ and x ′ in terms of w and x (or the other way around) it is easier at first to derive the inverse Lorentz transformation.
The above equations are alternate expressions for the t and x equations of the inverse Lorentz transformation, as can be seen by substituting ct for w, ct ′ for w ′, and v / c for β. From the inverse transformation, the equations of the forwards transformation can be derived by solving for t ′ and x ′. |
synth_fc_1873_rep7 | Positive | History | Entity search | Single | https://en.wikipedia.org/wiki/Battleship | 6 | Origin
In the first years of the 20th century, several navies worldwide experimented with the idea of a new type of battleship with a uniform armament of very heavy guns.
Admiral Vittorio Cuniberti, the Italian Navy's chief naval architect, articulated the concept of an all-big-gun battleship in 1903. When the Regia Marina did not pursue his ideas, Cuniberti wrote an article in Jane ' s proposing an "ideal" future British battleship, a large armored warship of 17,000 tons, armed solely with a single calibre main battery (twelve 12-inch guns), carrying 300-millimetre (12 in) belt armor, and capable of 24 knots (44 km/h).
The Russo-Japanese War provided operational experience to validate the "all-big-gun" concept. During the Battle of the Yellow Sea on August 10, 1904, Admiral Togo of the Imperial Japanese Navy commenced deliberate 12-inch gun fire at the Russian flagship Tzesarevich at 14,200 yards (13,000 meters). At the Battle of Tsushima on May 27, 1905, Russian Admiral Rozhestvensky's flagship fired the first 12-inch guns at the Japanese flagship Mikasa at 7,000 meters. It is often held that these engagements demonstrated the importance of the 12-inch (305 mm) gun over its smaller counterparts, though some historians take the view that secondary batteries were just as important as the larger weapons when dealing with smaller fast moving torpedo craft. Such was the case, albeit unsuccessfully, when the Russian battleship Knyaz Suvorov at Tsushima had been sent to the bottom by destroyer launched torpedoes. The 1903–04 design also retained traditional triple-expansion steam engines.
As early as 1904, Jackie Fisher had been convinced of the need for fast, powerful ships with an all-big-gun armament. If Tsushima influenced his thinking, it was to persuade him of the need to standardise on 12-inch (305 mm) guns. Fisher's concerns were submarines and destroyers equipped with torpedoes, then threatening to outrange battleship guns, making speed imperative for capital ships. Fisher's preferred option was his brainchild, the battlecruiser: lightly armored but heavily armed with eight 12-inch guns and propelled to 25 knots (46 km/h) by steam turbines.
It was to prove this revolutionary technology that Dreadnought was designed in January 1905, laid down in October 1905 and sped to completion by 1906. She carried ten 12-inch guns, had an 11-inch armor belt, and was the first large ship powered by turbines. She mounted her guns in five turrets; three on the centerline (one forward, two aft) and two on the wings, giving her at her launch twice the broadside of any other warship. She retained a number of 12-pound (3-inch, 76 mm) quick-firing guns for use against destroyers and torpedo-boats. Her armor was heavy enough for her to go head-to-head with any other ship in a gun battle, and conceivably win.
Dreadnought was to have been followed by three Invincible -class battlecruiser s, their construction delayed to allow lessons from Dreadnought to be used in their design. While Fisher may have intended Dreadnought to be the last Royal Navy battleship, the design was so successful he found little support for his plan to switch to a battlecruiser navy. Although there were some problems with the ship (the wing turrets had limited arcs of fire and strained the hull when firing a full broadside, and the top of the thickest armor belt lay below the waterline at full load), the Royal Navy promptly commissioned another six ships to a similar design in the Bellerophon and St. Vincent classes.
An American design, South Carolina, authorized in 1905 and laid down in December 1906, was another of the first dreadnoughts, but she and her sister, Michigan, were not launched until 1908. Both used triple-expansion engines and had a superior layout of the main battery, dispensing with Dreadnought ' s wing turrets. They thus retained the same broadside, despite having two fewer guns. |

Biological pigments include plant pigments and flower pigments. Many biological structures, such as skin, eyes, feathers, fur and hair contain pigments such as melanin in specialized cells called chromatophores. In some species, pigments accrue over very long periods during an individual's lifespan.
Pigment color differs from structural color in that it is the same for all viewing angles, whereas structural color is the result of selective reflection or iridescence, usually because of multilayer structures. For example, butterfly wings typically contain structural color, although many butterflies have cells that contain pigment as well. |

A 25th-anniversary stage performance was held in London on 1 and 2 October 2011 at the Royal Albert Hall and was screened live in cinemas worldwide. The production was produced by Cameron Mackintosh, directed by Laurence Connor, musical staging & choreography by Gillian Lynne, set design by Matt Kinley, costume design by Maria Björnson, lighting design by Patrick Woodroffe, and sound design by Mick Potter. The cast included Ramin Karimloo as the Phantom, Sierra Boggess as Christine, Hadley Fraser as Raoul, Wynne Evans as Piangi, Wendy Ferguson as Carlotta, Barry James as Monsieur Firmin, Gareth Snook as Monsieur Andre, Liz Robertson as Madame Giry, and Daisy Maywood as Meg Giry. Former West End Phantom Earl Carpenter played the Auctioneer. Lloyd Webber and several original cast members, including Crawford and Brightman, were in attendance, as well as Colm Wilkinson and Anthony Warlow who originated the role of the Phantom in Canada and Australia respectively. A DVD and Blu-ray of the performance was released in February 2012, and it began airing in March 2012 on PBS 's "Great Performances" television series.
In March 2012, a new production directed by Laurence Connor began a UK and Ireland tour to commemorate the 25th anniversary of the show, beginning at the Theatre Royal Plymouth and travelled to Manchester, Bristol, Dublin, Leeds, Edinburgh, Milton Keynes, Cardiff, and Southampton. John Owen-Jones and Earl Carpenter alternated as the Phantom, with Katie Hall as Christine and Simon Bailey as Raoul. In November 2019, the co-producers of The Phantom of the Opera, Mackintosh and Lloyd Webber's Really Useful Group (RUG), announced that the show would again tour the UK and Ireland, but this time with a return to the original production rather than the 2012 production. Although this announcement stated that the tour would be an "exact replica" of the musical on Broadway and in the West End, alterations were made to the set design in order to make the tour "lighter". These included a scaling down of the production's false proscenium, with the centrepiece Angel statue designed by Maria Björnson removed. Performances of this latest 2020 tour were suspended from 16 March 2020 as a result of the COVID-19 pandemic. In May 2020, Mackintosh and RUG announced the premature closure of the tour as a result. Rather than resume the tour following the end of COVID-19-related shutdowns, the producers installed that production into Her Majesty's Theatre in London in July 2021, where it replaced Hal Prince's original production. |
