The Romans, and more recently the Italians, planted elms in vineyards as supports for vines. Lopped at 3 m, the elms' quick growth, twiggy lateral branches, light shade, and root suckering made them ideal trees for this purpose. The lopped branches were used for fodder and firewood. Ovid in his Amores characterizes the elm as "loving the vine": ulmus amat vitem, vitis non deserit ulmum (the elm loves the vine, the vine does not desert the elm), and the ancients spoke of the "marriage" between elm and vine. |

Determinants can be used to describe the solutions of a linear system of equations, written in matrix form as A x = b {\displaystyle Ax=b}. This equation has a unique solution x {\displaystyle x} if and only if det (A) {\displaystyle \det(A)} is nonzero. In this case, the solution is given by Cramer's rule:
where A i {\displaystyle A_{i}} is the matrix formed by replacing the i {\displaystyle i} -th column of A {\displaystyle A} by the column vector b {\displaystyle b}. This follows immediately by column expansion of the determinant, i.e.
where the vectors a j {\displaystyle a_{j}} are the columns of A. The rule is also implied by the identity
Cramer's rule can be implemented in O (n 3) {\displaystyle \operatorname {O} (n^{3})} time, which is comparable to more common methods of solving systems of linear equations, such as LU, QR, or singular value decomposition. |

In management and organization science, trust is studied as a factor which organizational actors can manage and influence. Scholars have researched how trust develops across individual and organizational levels of analysis. They suggest a reciprocal process in which organizational structures influence people's trust and, at the same time, people's trust manifests in organizational structures. Trust is also one of the conditions of an organizational culture that supports knowledge sharing. An organizational culture that supports knowledge sharing allows employees to feel secure and comfortable to share their knowledge, their work, and their expertise. Structure often creates trust in a person, and this encourages them to feel comfortable and excel in the workplace; it makes an otherwise stressful environment manageable.
Management and organization science scholars have also studied how trust is influenced by contracts and how trust interacts with formal mechanisms. Scholars in management and related disciplines have also made a case for the importance of distrust as a related but distinct construct. Similarly scholars have assessed the relationship between monitoring and trust, for example in a trust game context, and in shareholder -management relations.
Since the mid-1990s, organizational research has followed two distinct but nonexclusive paradigms of trust research:
Together, these paradigms predict how different dimensions of trust form in organizations by demonstrating various trustworthiness attributes. |

This virtue concerns how people act with regards to donating/receiving money and things whose worth is valued in terms of money. The two extremes of deficiency and excess are wastefulness and stinginess, respectively.
Aristotle's approach to defining the correct balance is to treat money like any other useful thing, and say that virtue is to know how to use money: giving to the right people, in the right amount, at the right time. As with each of the ethical virtues, Aristotle emphasizes that a virtuous person is pleased to do the virtuous and beautiful thing.
It is better to err on the side of generosity: A liberal person "is more annoyed if he has not spent something that he ought than pained if he has spent something that he ought not".
Aristotle pointed out that we do not praise someone simply for not taking (which might however earn praise for being just). "t is more characteristic of virtue... to do what is noble than not to do what is base." He also points out that "generous people are loved practically the most of those who are recognized for virtue, since they confer benefits".
Aristotle says the source of donated money is important: "a decent sort of taking goes along with a decent sort of giving". Profligate people are often wasteful and stingy at the same time; when trying to be generous they often take from the wrong sources (for example pimps, loan sharks, gamblers, thieves), and give to the wrong people. Such people can be helped by guidance, unlike stingy people (and most people are somewhat stingy). Stinginess is the opposite of generosity, "both because it is a greater evil than wastefulness, and because people go wrong more often with it than from the sort of wastefulness described". |

Boomerangs are generally thrown in unobstructed, open spaces at least twice as large as the range of the boomerang. The flight direction to the left or right depends upon the design of the boomerang itself, not the thrower. A right-handed or left-handed boomerang can be thrown with either hand, but throwing a boomerang with the non-matching hand requires a throwing motion that many throwers find awkward. The following technique applies to a right-handed boomerang; the directions are mirrored for a left-handed boomerang. Different boomerang designs have different flight characteristics and are suitable for different conditions. The accuracy of the throw depends on understanding the weight and aerodynamics of that particular boomerang, and the strength, consistency and direction of the wind; from this, the thrower chooses the angle of tilt, the angle against the wind, the elevation of the trajectory, the degree of spin and the strength of the throw. A great deal of trial and error is required to perfect the throw over time.
A properly thrown boomerang will travel out parallel to the ground, sometimes climbing gently, perform a graceful, anti-clockwise, circular or tear-drop shaped arc, flatten out and return in a hovering motion, coming in from the left or spiralling in from behind. Ideally, the hover will allow a practiced catcher to clamp their hands shut horizontally on the boomerang from above and below, sandwiching the centre between their hands.
The grip used depends on size and shape; smaller boomerangs are held between finger and thumb at one end, while larger, heavier or wider boomerangs need one or two fingers wrapped over the top edge in order to induce a spin. The aerofoil-shaped section must face the inside of the thrower, and the flatter side outwards. It is usually inclined outwards, from a nearly vertical position to 20° or 30°; the stronger the wind, the closer to vertical. The elbow of the boomerang can point forwards or backwards, or it can be gripped for throwing; it just needs to start spinning on the required inclination, in the desired direction, with the right force.
The boomerang is aimed to the right of the oncoming wind; the exact angle depends on the strength of the wind and the boomerang itself. Left-handed boomerangs are thrown to the left of the wind and will fly a clockwise flight path. The trajectory is either parallel to the ground or slightly upwards. The boomerang can return without the aid of any wind, but even very slight winds must be taken into account however calm they might seem. Little or no wind is preferable for an accurate throw, light winds up to 3–5 knots (6–9 km/h; 3–6 mph) are manageable with skill. If the wind is strong enough to fly a kite, then it may be too strong unless a skilled thrower is using a boomerang designed for stability in stronger winds. Gusty days are a great challenge, and the thrower must be keenly aware of the ebb and flow of the wind strength, finding appropriate lulls in the gusts to launch their boomerang. |
synth_fc_1872_rep15 | Positive | History | Entity search | Single | https://en.wikipedia.org/wiki/Vadodara | 30 | Gujarat Sultanate
Muzaffar Shah I, founder of the Gujarat Sultanate, appointed his son Firuz Khan as governor of Vadodara at some point. After Muzaffar Shah's death in 1411, he was succeeded by his grandson Ahmad Shah I (Firuz's nephew). Firuz immediately laid claim to the throne. Because the sultanate's central authority in central and southern Gujarat was weak at this point, Firuz had little trouble assembling an army at Vadodara. He then marched to Nadiad and then to Bharuch, which he seized by force. Ultimately, the rebellion dissipated without a pitched battle: internal tensions had already arisen among Firuz Khan's main allies, and when Ahmad Shah offered them amnesty in return for standing down, they readily complied. Firuz Khan was forgiven and given Navsari as a jagir, thus giving up his position as governor of Vadodara.
In 1451, Vadodara was sacked by troops under Mahmud Khalji, ruler of the Malwa Sultanate. Later, during the reign of Mahmud Begada, a major re-foundation of Vadodara took place. A new city called Daulatabad was built, close to the old site. The Muslim name evidently did not stick, but the city itself did, and this new foundation became the basis for the modern city of Vadodara. A later atlas by John Ogilby refers to people moving from the old town to the new one. |

Failure to nominate an heir could invite chaotic, destructive wresting of power by a succession of competing claimants – a civil war. Too early a nomination could be seen as an abdication and reduce the chance for an orderly transmission of power. As Trajan lay dying, nursed by his wife, Plotina, and closely watched by Prefect Attianus, he could have lawfully adopted Hadrian as heir by means of a simple deathbed wish, expressed before witnesses; but when an adoption document was eventually presented, it was signed not by Trajan but by Plotina. That Hadrian was still in Syria was a further irregularity, as Roman adoption law required the presence of both parties at the adoption ceremony. Rumours, doubts, and speculation attended Hadrian's adoption and succession. It has been suggested that Trajan's young manservant Phaedimus, who died very soon after Trajan, was killed (or killed himself) rather than face awkward questions. Ancient sources are divided on the legitimacy of Hadrian's adoption: Cassius Dio saw it as bogus and the Historia Augusta writer as genuine. An aureus minted early in Hadrian's reign represents the official position; it presents Hadrian as Trajan's " Caesar " (Trajan's heir designate). |

Mudrocks are sedimentary rocks composed of at least 50% silt- and clay-sized particles. These relatively fine-grained particles are commonly transported by turbulent flow in water or air, and deposited as the flow calms and the particles settle out of suspension.
Most authors presently use the term "mudrock" to refer to all rocks composed dominantly of mud. Mudrocks can be divided into siltstones, composed dominantly of silt-sized particles; mudstones with subequal mixture of silt- and clay-sized particles; and claystones, composed mostly of clay-sized particles. Most authors use " shale " as a term for a fissile mudrock (regardless of grain size) although some older literature uses the term "shale" as a synonym for mudrock. |

The Summer Olympics have grown from 241 participants representing 14 nations in 1896, to more than 11,300 competitors representing 206 nations in 2020. The scope and scale of the Winter Olympics is smaller; for example, Beijing hosted 2,971 athletes from 91 nations in 2022. Most of the athletes and officials are housed in the Olympic Village for the duration of the Games. This accommodation centre is designed to be a self-contained home for all Olympic participants, and is furnished with cafeterias, health clinics, and locations for religious expression.
The IOC has allowed the formation of National Olympic Committees (NOCs) to represent individual nations. These do not meet the strict requirements for political sovereignty that other international organisations demand. As a result, colonies and dependencies are permitted to compete at Olympic Games, examples being territories such as Puerto Rico, Bermuda, and Hong Kong, all of which compete as separate nations despite being legally a part of another country. The current version of the Olympic Charter allows for the establishment of new NOCs to represent nations that qualify as "an independent State recognised by the international community". Consequently, the IOC did not allow the formation of NOCs for Sint Maarten and Curaçao when they gained the same constitutional status as Aruba in 2010, although the IOC had recognised the Aruban Olympic Committee in 1986. Since 2012, athletes from the former Netherlands Antilles have had the option to represent either the Netherlands or Aruba. |

After the 1928 Student Protests, women started participating more actively in politics. In 1935, women's rights supporters founded the Feminine Cultural Group (known as 'ACF' from its initials in Spanish), with the goal of tackling women's problems. The group supported women's political and social rights, and believed it was necessary to involve and inform women about these issues to ensure their personal development. It went on to give seminars, as well as founding night schools and the House of Laboring Women.
Groups looking to reform the 1936 Civil Code of Conduct in conjunction with the Venezuelan representation to the Union of American Women called the First Feminine Venezuelan Congress in 1940. In this congress, delegates discussed the situation of women in Venezuela and their demands. Key goals were women's suffrage and a reform to the Civil Code of Conduct. Around twelve thousand signatures were collected and handed to the Venezuelan Congress, which reformed the Civil Code of Conduct in 1942.
In 1944, groups supporting women's suffrage, the most important being Feminine Action, organized around the country. During 1945, women attained the right to vote at a municipal level. This was followed by a stronger call of action. Feminine Action began editing a newspaper called the Correo Cívico Femenino, to connect, inform and orientate Venezuelan women in their struggle. Finally, after the 1945 Venezuelan coup d'état and the call for a new Constitution, to which women were elected, women's suffrage became a constitutional right in the country. |

The importance of antibodies in health care and the biotechnology industry demands knowledge of their structures at high resolution. This information is used for protein engineering, modifying the antigen binding affinity, and identifying an epitope, of a given antibody. X-ray crystallography is one commonly used method for determining antibody structures. However, crystallizing an antibody is often laborious and time-consuming. Computational approaches provide a cheaper and faster alternative to crystallography, but their results are more equivocal, since they do not produce empirical structures. Online web servers such as Web Antibody Modeling (WAM) and Prediction of Immunoglobulin Structure (PIGS) enable computational modeling of antibody variable regions. Rosetta Antibody is a novel antibody F region structure prediction server, which incorporates sophisticated techniques to minimize CDR loops and optimize the relative orientation of the light and heavy chains, as well as homology models that predict successful docking of antibodies with their unique antigen. However, describing an antibody's binding site using only one single static structure limits the understanding and characterization of the antibody's function and properties. To improve antibody structure prediction and to take the strongly correlated CDR loop and interface movements into account, antibody paratopes should be described as interconverting states in solution with varying probabilities.
The ability to describe the antibody through binding affinity to the antigen is supplemented by information on antibody structure and amino acid sequences for the purpose of patent claims. Several methods have been presented for computational design of antibodies based on the structural bioinformatics studies of antibody CDRs.
There are a variety of methods used to sequence an antibody including Edman degradation, cDNA, etc.; albeit one of the most common modern uses for peptide/protein identification is liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). High volume antibody sequencing methods require computational approaches for the data analysis, including de novo sequencing directly from tandem mass spectra and database search methods that use existing protein sequence databases. Many versions of shotgun protein sequencing are able to increase the coverage by utilizing CID/HCD/ETD fragmentation methods and other techniques, and they have achieved substantial progress in attempt to fully sequence proteins, especially antibodies. Other methods have assumed the existence of similar proteins, a known genome sequence, or combined top-down and bottom up approaches. Current technologies have the ability to assemble protein sequences with high accuracy by integrating de novo sequencing peptides, intensity, and positional confidence scores from database and homology searches. |

The Vandals besieged Hippo in the spring of 430 when Augustine entered his final illness. According to Possidius, one of the few miracles attributed to Augustine, the healing of an ill man, took place during the siege. Augustine has been cited to have excommunicated himself upon the approach of his death in an act of public penance and solidarity with sinners. Spending his final days in prayer and repentance, he requested the penitential Psalms of David be hung on his walls so he could read them and upon which led him to " freely and constantly" according to Posiddius' biography. He directed the library of the church in Hippo and all the books therein should be carefully preserved. He died on 28 August 430. Shortly after his death, the Vandals lifted the siege of Hippo, but they returned soon after and burned the city. They destroyed all but Augustine's cathedral and library, which they left untouched.
Augustine was canonized by popular acclaim, and later recognized as a Doctor of the Church in 1298 by Pope Boniface VIII. His feast day is 28 August, the day on which he died. He is considered the patron saint of brewers, printers, theologians, and a number of cities and dioceses. He is invoked against sore eyes.

A variant of Gaussian elimination called Gauss–Jordan elimination can be used for finding the inverse of a matrix, if it exists. If A is an n × n square matrix, then one can use row reduction to compute its inverse matrix, if it exists. First, the n × n identity matrix is augmented to the right of A, forming an n × 2 n block matrix. Now through application of elementary row operations, find the reduced echelon form of this n × 2 n matrix. The matrix A is invertible if and only if the left block can be reduced to the identity matrix I; in this case the right block of the final matrix is A. If the algorithm is unable to reduce the left block to I, then A is not invertible.
For example, consider the following matrix: A =. {\displaystyle A={\begin{bmatrix}2&-1&0\\-1&2&-1\\0&-1&2\end{bmatrix}}.}
To find the inverse of this matrix, one takes the following matrix augmented by the identity and row-reduces it as a 3 × 6 matrix: =. {\displaystyle =\left.}
By performing row operations, one can check that the reduced row echelon form of this augmented matrix is =. {\displaystyle =\left.}
One can think of each row operation as the left product by an elementary matrix. Denoting by B the product of these elementary matrices, we showed, on the left, that BA = I, and therefore, B = A. On the right, we kept a record of BI = B, which we know is the inverse desired. This procedure for finding the inverse works for square matrices of any size. |

To illustrate this, consider a floating point representation with a 4-bit significand:
Even though most computers compute with 24 or 53 bits of significand, this is still an important source of rounding error, and approaches such as the Kahan summation algorithm are ways to minimise the errors. It can be especially problematic in parallel computing. |

The initial symptoms are followed by a stage called clinical latency, asymptomatic HIV, or chronic HIV. Without treatment, this second stage of the natural history of HIV infection can last from about three years to over 20 years (on average, about eight years). While typically there are few or no symptoms at first, near the end of this stage many people experience fever, weight loss, gastrointestinal problems and muscle pains. Between 50% and 70% of people also develop persistent generalized lymphadenopathy, characterized by unexplained, non-painful enlargement of more than one group of lymph nodes (other than in the groin) for over three to six months.
Although most HIV-1 infected individuals have a detectable viral load and in the absence of treatment will eventually progress to AIDS, a small proportion (about 5%) retain high levels of CD4 T cells (T helper cells) without antiretroviral therapy for more than five years. These individuals are classified as "HIV controllers" or long-term nonprogressors (LTNP). Another group consists of those who maintain a low or undetectable viral load without anti-retroviral treatment, known as "elite controllers" or "elite suppressors". They represent approximately 1 in 300 infected persons. |

synth_fc_2190_rep8 | Positive | Law | Entity search | Multi | https://en.wikipedia.org/wiki/Property_crime | 1 | Property crime is a category of crime, usually involving private property, that includes, among other crimes, burglary, larceny, theft, motor vehicle theft, arson, shoplifting, and vandalism. Property crime is a crime to obtain money, property, or some other benefit. This may involve force, or the threat of force, in cases like robbery or extortion. Since these crimes are committed in order to enrich the perpetrator they are considered property crimes. Crimes against property are divided into two groups: destroyed property and stolen property. When property is destroyed, it could be called arson or vandalism. Examples of the act of stealing property is robbery or embezzlement. Property crimes are high-volume crimes, with cash, electronics, power tools, cameras, and jewelry often targeted. "Hot products" tend to be items that are concealable, removable, available, valuable, and enjoyable, with an ease of "disposal" being the most important characteristic. |
synth_fc_320_rep20 | Positive | Board game | Order | Multi | https://en.wikipedia.org/wiki/Mahjong | 36 | Repeated hands
If the dealer wins the hand, they will remain the dealer and an extra hand is played in addition to the minimum 16 hands in a match.
An extra hand is also played if there is no winner by the time all the tiles in the wall have been drawn. When there is no winner it is known as a "goulash hand". Depending on table rules, the winner of the next game may take an agreed number of points from each player, carrying over the points from the non-winning hand to the winning one. If there are two or three goulash hands in a row then the winner would collect a considerable number of points from each player on top of their scoring hand. Because extra hands may be played every time a dealer wins or if there is a goulash hand, a match of 16 hands can easily become a match of 20 or even much more.
As table rules add a large amount of flexibility for players, they can choose to disregard the rule of extra hands and pass on the dealership regardless of who wins or if it results in a goulash hand. This puts a maximum estimated limit on the game duration and provides some amount of predictability. |
synth_fc_1699_rep13 | Positive | Health | API setting | Single | https://en.wikipedia.org/wiki/Correlation | 13 | Sensitivity to the data distribution
The degree of dependence between variables X and Y does not depend on the scale on which the variables are expressed. That is, if we are analyzing the relationship between X and Y, most correlation measures are unaffected by transforming X to a + bX and Y to c + dY, where a, b, c, and d are constants (b and d being positive). This is true of some correlation statistics as well as their population analogues. Some correlation statistics, such as the rank correlation coefficient, are also invariant to monotone transformations of the marginal distributions of X and/or Y.
Most correlation measures are sensitive to the manner in which X and Y are sampled. Dependencies tend to be stronger if viewed over a wider range of values. Thus, if we consider the correlation coefficient between the heights of fathers and their sons over all adult males, and compare it to the same correlation coefficient calculated when the fathers are selected to be between 165 cm and 170 cm in height, the correlation will be weaker in the latter case. Several techniques have been developed that attempt to correct for range restriction in one or both variables, and are commonly used in meta-analysis; the most common are Thorndike's case II and case III equations.
Various correlation measures in use may be undefined for certain joint distributions of X and Y. For example, the Pearson correlation coefficient is defined in terms of moments, and hence will be undefined if the moments are undefined. Measures of dependence based on quantiles are always defined. Sample-based statistics intended to estimate population measures of dependence may or may not have desirable statistical properties such as being unbiased, or asymptotically consistent, based on the spatial structure of the population from which the data were sampled.
Sensitivity to the data distribution can be used to an advantage. For example, scaled correlation is designed to use the sensitivity to the range in order to pick out correlations between fast components of time series. By reducing the range of values in a controlled manner, the correlations on long time scale are filtered out and only the correlations on short time scales are revealed. |

Leisure is a major part of the London economy. A 2003 report attributed a quarter of the entire UK leisure economy to London at 25.6 events per 1000 people. The city is one of the four fashion capitals of the world, and, according to official statistics, is the world's third-busiest film production centre, presents more live comedy than any other city, and has the biggest theatre audience of any city in the world.
Within the City of Westminster, the entertainment district of the West End has its focus around Leicester Square, where London and world film premieres are held, and Piccadilly Circus, with its giant electronic advertisements. London's theatre district is here, as are many cinemas, bars, clubs, and restaurants, including the city's Chinatown district (in Soho), and just to the east is Covent Garden, an area housing speciality shops. In 1881, the West End's Savoy Theatre, which was built to showcase the plays of Gilbert and Sullivan, was fitted with the incandescent light bulb developed by Sir Joseph Swan to become the first public building in the world to be lit entirely by electricity. The city is the home of Andrew Lloyd Webber, whose musicals have dominated West End theatre since the late 20th century. Agatha Christie 's The Mousetrap, the world's longest-running play, has been performed in the West End since 1952. The Laurence Olivier Awards –named after Laurence Olivier –are given annually by the Society of London Theatre. The Royal Ballet, English National Ballet, Royal Opera, and English National Opera are based in London and perform at the Royal Opera House, the London Coliseum, Sadler's Wells Theatre, and the Royal Albert Hall, as well as touring the country.
Islington 's 1 mile (1.6 km) long Upper Street, extending northwards from Angel, has more bars and restaurants than any other street in the UK. Europe's busiest shopping area is Oxford Street, a shopping street nearly 1 mile (1.6 km) long, making it the longest shopping street in the UK. It is home to vast numbers of retailers and department stores, including Selfridges flagship store. Knightsbridge, home to the equally renowned Harrods department store, lies to the south-west. One of the world's largest retail destinations, London frequently ranks at or near the top of retail sales of any city. Opened in 1760 with its flagship store on Regent Street since 1881, Hamleys is the oldest toy store in the world. Madame Tussauds wax museum opened in Baker Street in 1835, an era viewed as being when London's tourism industry began.
London is home to designers John Galliano, Stella McCartney, Manolo Blahnik, and Jimmy Choo, among others; its renowned art and fashion schools make it one of the four international centres of fashion. Mary Quant designed the miniskirt in her King's Road boutique in Swinging Sixties London. In 2017, London was ranked the top city for luxury store openings. London Fashion Week takes place twice a year, in February and September; Londoners on the catwalk have included Naomi Campbell, Kate Moss and Cara Delevingne.
London offers a great variety of cuisine as a result of its ethnically diverse population. Gastronomic centres include the Bangladeshi restaurants of Brick Lane and the Chinese restaurants of Chinatown. There are Chinese takeaways throughout London, as are Indian restaurants which provide Indian and Anglo-Indian cuisine. Around 1860, the first fish and chips shop in London was opened by Joseph Malin, a Jewish immigrant, in Bow. The full English breakfast dates from the Victorian era, and many cafes in London serve a full English throughout the day. London has five 3-Michelin star restaurants, including Restaurant Gordon Ramsay in Chelsea. Many hotels in London provide a traditional afternoon tea service, such as the Oscar Wilde Lounge at the Hotel Café Royal in Piccadilly, and a themed tea service is also available, for example an Alice in Wonderland themed afternoon tea served at the Egerton House Hotel, and Charlie and the Chocolate Factory themed afternoon tea at One Aldwych in Covent Garden. The nation's most popular biscuit to dunk in tea, chocolate digestives have been manufactured by McVitie's at their Harlesden factory in north-west London since 1925.
There is a variety of annual events, beginning with the relatively new New Year's Day Parade, a fireworks display at the London Eye; the world's second largest street party, the Notting Hill Carnival, is held on the late August Bank Holiday each year. Traditional parades include November's Lord Mayor's Show, a centuries-old event celebrating the annual appointment of a new Lord Mayor of the City of London with a procession along the streets of the city, and June's Trooping the Colour, a formal military pageant performed by regiments of the Commonwealth and British armies to celebrate the King's Official Birthday. The Boishakhi Mela is a Bengali New Year festival celebrated by the British Bangladeshi community. It is the largest open-air Asian festival in Europe. After the Notting Hill Carnival, it is the second-largest street festival in the United Kingdom attracting over 80,000 visitors. First held in 1862, the RHS Chelsea Flower Show (run by the Royal Horticultural Society) takes place in May every year. |

He was mainly known for his comedic roles, but also for his portrayal of Willy Wonka in Willy Wonka & the Chocolate Factory (1971). He collaborated with Mel Brooks on the films The Producers (1967), Blazing Saddles (1974) and Young Frankenstein (1974), and with Richard Pryor in the films Silver Streak (1976), Stir Crazy (1980), See No Evil, Hear No Evil (1989) and Another You (1991). He began his career on stage, and made his screen debut in an episode of the TV series The Play of the Week in 1961. His first film role was that of a hostage in the 1967 motion picture Bonnie and Clyde. His first major film role was as Leopold Bloom in the 1967 film The Producers, for which he was nominated for an Academy Award for Best Supporting Actor. It was the first in a series of collaborations with writer/director Mel Brooks, including Young Frankenstein, which Wilder co-wrote, garnering the pair an Academy Award nomination for Best Adapted Screenplay. He also starred in Woody Allen's Everything You Always Wanted to Know About Sex* (1972). Wilder directed and wrote several of his own films, including The Woman in Red (1984). With his third wife, Gilda Radner, he starred in three films, the last two of which he also directed. Her 1989 death from ovarian cancer led to his active involvement in promoting cancer awareness and treatment, helping found the Gilda Radner Ovarian Cancer Detection Center in Los Angeles and co-founding Gilda's Club. After his last acting performance in 2003—a guest role on Will & Grace, for which he received a Primetime Emmy Award for Outstanding Guest Actor in a Comedy Series—Wilder turned his attention to writing. He produced a memoir, Kiss Me Like a Stranger (2005) and five other books. |
synth_fc_2817_rep21 | Negative | Physics & Chemistry | Feature search | Single | https://en.wikipedia.org/wiki/Baryon | 9 | Parity
If the universe were reflected in a mirror, most of the laws of physics would be identical—things would behave the same way regardless of what we call "left" and what we call "right". This concept of mirror reflection is called " intrinsic parity " or simply "parity" (P). Gravity, the electromagnetic force, and the strong interaction all behave in the same way regardless of whether or not the universe is reflected in a mirror, and thus are said to conserve parity (P-symmetry). However, the weak interaction does distinguish "left" from "right", a phenomenon called parity violation (P-violation).
Based on this, if the wavefunction for each particle (in more precise terms, the quantum field for each particle type) were simultaneously mirror-reversed, then the new set of wavefunctions would perfectly satisfy the laws of physics (apart from the weak interaction). It turns out that this is not quite true: for the equations to be satisfied, the wavefunctions of certain types of particles have to be multiplied by −1, in addition to being mirror-reversed. Such particle types are said to have negative or odd parity (P = −1, or alternatively P = –), while the other particles are said to have positive or even parity (P = +1, or alternatively P = +).
For baryons, the parity is related to the orbital angular momentum by the relation:
As a consequence, baryons with no orbital angular momentum (L = 0) all have even parity (P = +). |

Astrophysics is the branch of astronomy that employs the principles of physics and chemistry "to ascertain the nature of the astronomical objects, rather than their positions or motions in space". Among the objects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. Their emissions are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, astrophysicists typically apply many disciplines of physics, including mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics.
In practice, modern astronomical research often involves a substantial amount of work in the realms of theoretical and observational physics. Some areas of study for astrophysicists include their attempts to determine the properties of dark matter, dark energy, and black holes; whether or not time travel is possible, wormholes can form, or the multiverse exists; and the origin and ultimate fate of the universe. Topics also studied by theoretical astrophysicists include Solar System formation and evolution; stellar dynamics and evolution; galaxy formation and evolution; magnetohydrodynamics; large-scale structure of matter in the universe; origin of cosmic rays; general relativity and physical cosmology, including string cosmology and astroparticle physics. |
synth_fc_856_rep16 | Positive | Finance | Calculation | Multi | https://en.wikipedia.org/wiki/House_of_Medici | 1 | The House of Medici (English: / ˈ m ɛ d ɪ tʃ i / MED -itch-ee, UK also / m ə ˈ d iː tʃ i / mə- DEE -chee; Italian:) was an Italian banking family and political dynasty that first consolidated power in the Republic of Florence under Cosimo de' Medici during the first half of the 15th century. The family originated in the Mugello region of Tuscany, and prospered gradually until it was able to fund the Medici Bank. This bank was the largest in Europe during the 15th century and facilitated the Medicis' rise to political power in Florence, although they officially remained citizens rather than monarchs until the 16th century.
The Medici produced four popes of the Catholic Church— Pope Leo X (1513–1521), Pope Clement VII (1523–1534), Pope Pius IV (1559–1565) and Pope Leo XI (1605)—and two queens of France— Catherine de' Medici (1547–1559) and Marie de' Medici (1600–1610). In 1532, the family acquired the hereditary title Duke of Florence. In 1569, the duchy was elevated to the Grand Duchy of Tuscany after territorial expansion. The Medici ruled the Grand Duchy from its inception until 1737, with the death of Gian Gastone de' Medici. The grand duchy witnessed degrees of economic growth under the early grand dukes, but was bankrupt by the time of Cosimo III de' Medici (r. 1670–1723).
The Medicis' wealth and influence was initially derived from the textile trade guided by the wool guild of Florence, the Arte della Lana. Like other families ruling in Italian signorie, the Medici dominated their city's government, were able to bring Florence under their family's power, and created an environment in which art and humanism flourished. The Italian Renaissance was inspired by the Medici along with other families of Italy, such as the Visconti and Sforza in Milan, the Este in Ferrara, the Borgia and Della Rovere in Rome, and the Gonzaga in Mantua.
The Medici Bank, from when it was created in 1397 to its fall in 1494, was one of the most prosperous and respected institutions in Europe, and the Medici family was considered the wealthiest in Europe for a time. From this base, they acquired political power initially in Florence and later in wider Italy and Europe. They were among the earliest businesses to use the general ledger system of accounting through the development of the double-entry bookkeeping system for tracking credits and debits.
The Medici family have claimed to have funded the invention of the piano and opera, financed the construction of Saint Peter's Basilica and Santa Maria del Fiore, and were patrons of Brunelleschi, Botticelli, Leonardo da Vinci, Michelangelo, Raphael, Machiavelli, Galileo, and Francesco Redi, among many others in the arts and sciences. They were also protagonists of the Counter-Reformation, from the beginning of the Reformation through the Council of Trent and the French Wars of Religion. |

Reduced to the position of an adventurer, Tokhtamysh made his way across the territory of the Golden Horde to its peripheral Siberian possessions. Here he succeeded in bringing parts of the area under his control in 1400, and by 1405 was attempting to ingratiate himself with his protector-turned-enemy, Timur, who had just quarreled with Edigu. Timur's death in February 1405 made any rapprochement moot. Throughout this period, Tokhtamysh naturally attracted the hostility of Edigu and his new puppet khan, Shādī Beg. Edigu is said to have fought Tokhtamysh on sixteen separate occasions between 1400 and 1406; in the final instance, after a reverse at the hands of Tokhtamysh, Edigu spread a rumor about his own death to draw Tokhtamysh out into the open and have him killed in a hail of darts and spears, late in 1406, near Tyumen. Khan Shādī Beg apparently claimed or was given credit for the death of Tokhtamysh, while others credited Edigu or Edigu's son Nūr ad-Dīn. Russian chroniclers recorded his death in 1406:
Тое же зимы царь Женибек уби Тактамыша в Сибирскои земли близ Тюмени, а сам седе на Орде.
That same winter, tsar Shadi Beg killed Tokhtamysh in the Siberian lands near Tyumen, and he himself sat on the Horde. |

Oil strikes started in fall of 1978 and led to a 4.8 million drop of crude oil production every day, which was about seven percent of the world's supply. Prices rose from 13 dollars per barrel in 1979 to 34 dollars in 1980. While increased production from other countries, like Saudi Arabia, offset the decline in supply slightly there was still a 10 percent drop in available oil.
There were a variety of factors influencing the workers' decision to strike. The Shah's regime had relaxed oppression in 1977, giving people more access to protest and organizing. At the same time, the economy had faltered after doing better in the early 70s. The strikes began when the workers at a refinery in Tehran called for higher wages and housing allowances. The government ignored the request, causing the workers to strike. The Shah's government responded by killing dozens of strikers in an event known as Black Friday. One day after this massacre, strikes began in Tehran, Abadan, Isfahan, Shiraz, and Kermanshah. This began the first wave of strikes, which SAVAK reports to include 11,000 workers. The oil strikes of 1978 were imperative to the Iranian Revolution's success, as they put extreme economic pressure on the Shah's regime. Oil revenues are a significant part of the government's income and regardless of the motivation behind those who strike, oil strikes will always threaten to destabilize Iranian regimes.
By late October, a nationwide general strike was declared, with workers in virtually all major industries walking off their jobs, most damagingly in the oil industry and the print media. Special "strike committees" were set up throughout major industries to organize and coordinate the activities.
The Shah did not attempt to crack down on strikers, but instead gave them generous wage increases, and allowed strikers who lived in government housing to remain in their homes. By the beginning of November, many important officials in the Shah's government were demanding from the Shah forceful measures to bring the strikers back to work. |
synth_fc_1558_rep20 | Positive | Geography | Feature search | Single | https://en.wikipedia.org/wiki/Theorema_Egregium | 2 | Elementary applications
A sphere of radius R has constant Gaussian curvature which is equal to 1/ R. At the same time, a plane has zero Gaussian curvature. As a corollary of Theorema Egregium, a piece of paper cannot be bent onto a sphere without crumpling. Conversely, the surface of a sphere cannot be unfolded onto a flat plane without distorting the distances. If one were to step on an empty egg shell, its edges have to split in expansion before being flattened. Mathematically, a sphere and a plane are not isometric, even locally. This fact is significant for cartography: it implies that no planar (flat) map of Earth can be perfect, even for a portion of the Earth's surface. Thus every cartographic projection necessarily distorts at least some distances.
The catenoid and the helicoid are two very different-looking surfaces. Nevertheless, each of them can be continuously bent into the other: they are locally isometric. It follows from Theorema Egregium that under this bending the Gaussian curvature at any two corresponding points of the catenoid and helicoid is always the same. Thus isometry is simply bending and twisting of a surface without internal crumpling or tearing, in other words without extra tension, compression, or shear.
An application of the theorem is seen when a flat object is somewhat folded or bent along a line, creating rigidity in the perpendicular direction. This is of practical use in construction, as well as in a common pizza -eating strategy: A flat slice of pizza can be seen as a surface with constant Gaussian curvature 0. Gently bending a slice must then roughly maintain this curvature (assuming the bend is roughly a local isometry). If one bends a slice horizontally along a radius, non-zero principal curvatures are created along the bend, dictating that the other principal curvature at these points must be zero. This creates rigidity in the direction perpendicular to the fold, an attribute desirable for eating pizza, as it holds its shape long enough to be consumed without a mess. This same principle is used for strengthening in corrugated materials, most familiarly with corrugated fiberboard and corrugated galvanised iron, and in some forms of potato chips as well. |
synth_fc_2320_rep14 | No function call | Law | Entity search | Single | https://en.wikipedia.org/wiki/Daniel_Defoe | 25 | Pamphleteering and prison
Defoe's first notable publication was An Essay Upon Projects, a series of proposals for social and economic improvement, published in 1697. From 1697 to 1698, he defended the right of King William III to a standing army during disarmament, after the Treaty of Ryswick (1697) had ended the Nine Years' War (1688–1697). His most successful poem, The True-Born Englishman (1701), defended William against xenophobic attacks from his political enemies in England, and English anti-immigration sentiments more generally. In 1701, Defoe presented the Legion's Memorial to Robert Harley, then Speaker of the House of Commons —and his subsequent employer—while flanked by a guard of sixteen gentlemen of quality. It demanded the release of the Kentish petitioners, who had asked Parliament to support the king in an imminent war against France.
The death of William III in 1702 once again created a political upheaval, as the king was replaced by Queen Anne who immediately began her offensive against Nonconformists. Defoe was a natural target, and his pamphleteering and political activities resulted in his arrest and placement in a pillory on 31 July 1703, principally on account of his December 1702 pamphlet entitled The Shortest-Way with the Dissenters; Or, Proposals for the Establishment of the Church, purporting to argue for their extermination. In it, he ruthlessly satirised both the high church Tories and those Dissenters who hypocritically practised so-called "occasional conformity", such as his Stoke Newington neighbour Sir Thomas Abney. It was published anonymously, but the true authorship was quickly discovered and Defoe was arrested. He was charged with seditious libel and found guilty in a trial at the Old Bailey in front of the notoriously sadistic judge Salathiel Lovell. Lovell sentenced him to a punitive fine of 200 marks (£336 then, £ 71,883 in 2024), to public humiliation in a pillory, and to an indeterminate length of imprisonment which would only end upon the discharge of the punitive fine. According to legend, the publication of his poem Hymn to the Pillory caused his audience at the pillory to throw flowers instead of the customary harmful and noxious objects and to drink to his health. The truth of this story is questioned by most scholars, although John Robert Moore later said that "no man in England but Defoe ever stood in the pillory and later rose to eminence among his fellow men".
"Wherever God erects a house of prayer the Devil always builds a chapel there; And 't will be found, upon examination, the latter has the largest congregation."
– Defoe's The True-Born Englishman, 1701
After his three days in the pillory, Defoe went into Newgate Prison. Robert Harley, 1st Earl of Oxford and Earl Mortimer, brokered his release in exchange for Defoe's cooperation as an intelligence agent for the Tories. In exchange for such cooperation with the rival political side, Harley paid some of Defoe's outstanding debts, improving his financial situation considerably.
Within a week of his release from prison, Defoe witnessed the Great Storm of 1703, which raged through the night of 26/27 November. It caused severe damage to London and Bristol, uprooted millions of trees, and killed more than 8,000 people, mostly at sea. The event became the subject of Defoe's The Storm (1704), which includes a collection of witness accounts of the tempest. Many regard it as one of the world's first examples of modern journalism.
In the same year, he set up his periodical A Review of the Affairs of France, which supported the Harley Ministry, chronicling the events of the War of the Spanish Succession (1702–1714). The Review ran three times a week without interruption until 1713. Defoe was amazed that a man as gifted as Harley left vital state papers lying in the open, and warned that he was almost inviting an unscrupulous clerk to commit treason; his warnings were fully justified by the William Gregg affair.
When Harley was ousted from the ministry in 1708, Defoe continued writing the Review to support Godolphin, then again to support Harley and the Tories in the Tory ministry of 1710–1714. The Tories fell from power with the death of Queen Anne, but Defoe continued doing intelligence work for the Whig government, writing "Tory" pamphlets that undermined the Tory point of view.
Not all of Defoe's pamphlet writing was political. One pamphlet was originally published anonymously, entitled A True Relation of the Apparition of One Mrs. Veal the Next Day after her Death to One Mrs. Bargrave at Canterbury The 8th of September, 1705. It deals with the interaction between the spiritual realm and the physical realm and was most likely written in support of Charles Drelincourt 's The Christian Defence against the Fears of Death (1651). It describes Mrs. Bargrave's encounter with her old friend Mrs. Veal after she had died. It is clear from this piece and other writings that the political portion of Defoe's life was by no means his only focus. |

In 1997, Novoselic, Grohl and Love formed the limited liability company Nirvana LLC to oversee Nirvana projects. A 45-track box set of Nirvana rarities was scheduled for release in October 2001. However, shortly before the release date, Love filed a suit to dissolve Nirvana LLC, and an injunction was issued preventing the release of any new Nirvana material until the case was resolved. Love contended that Cobain was Nirvana, that Grohl and Novoselic were sidemen, and that she had signed the partnership agreement originally under bad advice. Grohl and Novoselic countersued, asking the court to remove Love from the partnership and to replace her with another representative of Cobain's estate.
The day before the case was set to go to trial in October 2002, Love, Novoselic, and Grohl announced that they had reached a settlement. The next month, the best-of compilation Nirvana was released, featuring the previously unreleased track " You Know You're Right ", the last song Nirvana recorded. It debuted at number three on the Billboard album chart. The box set, With the Lights Out, was released in November 2004.

Djokovic and Andy Murray have met 36 times, with Djokovic leading 25–11. Djokovic leads on hard courts 20–8 and 5–1 on clay, while Murray has won the two matches played on grass. Djokovic and Murray are one of two pairs to have met in each of the four major finals (the other pair being Djokovic and Nadal). The two are almost exactly the same age, with Murray being a week older than Djokovic, so they progressed through the ranks of the junior circuit together, and Murray was the winner of the first match they ever played as teenagers at Les Petits As in 2001. They were the 2015 and 2016 year-end top two players in the world, with the battle for the 2016 year-end No. 1 only being decided in the final of the World Tour Finals, which was won by Murray in straight sets.
One of their most notable matches was a three-set thriller at the final of the 2012 Shanghai Masters, in which Djokovic saved five championship points to win his first Shanghai Masters title and end Murray's 12–0 winning streak at the event. Tennis pundits have classified many more of their matches as instant classics, such as the 2011 Italian Open semifinals, the 2012 Australian Open semifinal, 2012 US Open final, the 2015 semifinal and 2016 final at the French Open, and the 2017 Qatar Open final. |

From 1892 to 1895, Dvořák was the director of the National Conservatory of Music in New York City. The Conservatory's President, Jeannette Thurber, offered Dvořák an annual salary of $15,000 – an incredibly lavish sum for the era (equivalent to $508,667 in 2023), twenty-five times what he was paid at the Prague Conservatory. Emanuel Rubin describes the Conservatory and Dvořák's time there. Thurber, a wealthy and philanthropic woman, made it open to women and black students as well as white men, which was unusual for the times. Dvořák's original contract provided for three hours a day of work, including teaching and conducting, six days a week, with four months of vacation each summer. The Panic of 1893, a severe economic depression, depleted the assets of the Thurber family and other patrons of the Conservatory. In 1894, Dvořák's salary was cut to $8,000 per year and moreover was paid only irregularly. The Conservatory was located at 126–128 East Seventeenth Street, but was demolished in 1911 and replaced by what is today a high school.
Dvořák's main goal in America was to discover "American Music" and engage in it, much as he had used Czech folk idioms within his music. Shortly after his arrival in America in 1892, Dvořák wrote a series of newspaper articles reflecting on the state of American music. He supported the concept that African-American and Native American music should be used as a foundation for the growth of American music. He felt that through the music of Native Americans and African-Americans, Americans would find their own national style of music. Here Dvořák met Harry Burleigh, who later became one of the earliest African-American composers. Burleigh introduced Dvořák to traditional African-American spirituals.
In the winter and spring of 1893, Dvořák was commissioned by the New York Philharmonic to write Symphony No. 9, From the New World, which was premiered under the baton of Anton Seidl, to tumultuous applause. Clapham writes that "without question this was one of the greatest triumphs, and very possibly the greatest triumph of all that Dvořák experienced" in his life, and when the Symphony was published it was "seized on by conductors and orchestras" all over the world.
Two months before leaving for America, Dvořák had hired as secretary Josef Jan Kovařík, who had just finished violin studies at the Prague Conservatory and was about to return to his home in the United States. There he continued to serve as Dvořák's secretary and lived with the Dvořák family. He had come from the Czech -speaking community of Spillville, Iowa, where his father Jan Josef Kovařík was a schoolmaster. Dvořák decided to spend the summer of 1893 in Spillville, along with all his family; he referred to it as his "summer Vysoka." While there he composed the String Quartet in F (the "American") and the String Quintet in E ♭ major. Back in New York that autumn, he composed his Sonatina for violin and piano. He also conducted a performance of his Eighth Symphony at the Columbian Exposition in Chicago that same year.
In the winter of 1894–95, Dvořák wrote his Cello Concerto in B minor, Op. 104, B. 191, completed in February 1895. However, due to homesickness, his partially unpaid salary, and increasing recognition in Europe – he had been made an honorary member of the Gesellschaft der Musikfreunde in Vienna – he decided to return to Bohemia. He informed Thurber that he was leaving. Dvořák and his wife left New York before the end of the spring term, with no intention of returning.
Dvořák's New York home was located at 327 East Seventeenth Street, near the intersection of what is today called Perlman Place. It was in this house that both the B minor Cello Concerto and the New World Symphony were written within a few years. Despite protests, from Czech President Václav Havel amongst others who wanted the house preserved as a historical site, it was demolished in 1991 to make room for a Beth Israel Medical Center residence for people with AIDS. In 2017, this residence was converted into a homeless shelter. To honor Dvořák, a statue of him was erected in nearby Stuyvesant Square.
Brahms continued to try to "clear a path for" Dvořák, "the only contemporary whom he considered really worthy". While Dvořák was in America, Simrock was still publishing his music in Germany, and Brahms corrected proofs for him. Dvořák said it was hard to understand why Brahms would "take on the very tedious job of proofreading. I don't believe there is another musician of his stature in the whole world who would do such a thing." |

Stone inscriptions were the most common form of documents used on temple walls, boundary of properties and open places for public display. Another form of documentation was on copper plates that were meant for record keeping. Usually verbose inscriptions included information such as a salutation, a panegyric of the emperor or local ruler, the name of the donor, nature of the endowment (generally either cash or produce), the manner in which the grant would be used, obligations of the donee, share received by the donor and a concluding statement that officiated the entire donation and its obligations. Some inscriptions record an instance of victory in war or religious festival, and retribution or a curse on those who do not honor the grant.
Most Vijayanagara inscriptions recovered so far are in Kannada, Telugu and Tamil, and a few in Sanskrit. According to Suryanath U. Kamath about 7000 stone inscriptions, half of which are in Kannada, and about 300 copper plates which are mostly in Sanskrit, have been recovered. Bilingual inscriptions had lost favor by the 14th century. According to Mack, the majority of the inscriptions recovered are from the rule of the Tuluva dynasty (from 1503 to 1565) with the Saluva dynasty (from 1485 to 1503) inscribing the least in its brief control over the empire. The Sangama dynasty (from 1336 to 1485) which ruled the longest produced about one third of all epigraphs inscribed during the Tuluva period. Despite the popularity of Telugu language as a literary medium, the majority of the epigraphs in the language were inscribed in the limited period from 1500 to 1649. Talbot explains this scenario as one of shifting political solidarity. The Vijayanagara Empire was originally founded in Karnataka, with Andhra Pradesh serving as a province of the empire. After its defeat to the Deccan sultanates in 1565 and the sacking of the royal capital Vijayanagara, the diminished empire moved its capital to Southern Andhra Pradesh, creating an enterprise dominated by Telugu language.
The Persian visitor Abdur Razzak wrote in his travelogues that the empire enjoyed a high level of monetization. This is especially evident from the number of temple cash grants that were made. Coins were minted using gold, silver, copper and brass and their value depended on material weight. Coins were minted by the state, in the provinces and by merchant guilds. Foreign currency was in circulation. The highest denomination was the gold Varaha (or Hun/Honnu, Gadyana) weighted 50.65 – 53 grains. The Partab or Pratapa was valued at half a Varaha, the Fanam, Phanam or Hana, an alloy of gold and copper was the most common currency valued at a third of the Varaha. A Tar made of pure silver was a sixth of a Phanam and a Chital made of brass was a third of the Tar. Haga, Visa and Kasu were also coins of lower denominations. |

The size and type of magnet and details of the magnetic circuit differ, depending on design goals. For instance, the shape of the pole piece affects the magnetic interaction between the voice coil and the magnetic field, and is sometimes used to modify a driver's behavior. A shorting ring, or Faraday loop, may be included as a thin copper cap fitted over the pole tip or as a heavy ring situated within the magnet-pole cavity. The benefits of this complication is reduced impedance at high frequencies, providing extended treble output, reduced harmonic distortion, and a reduction in the inductance modulation that typically accompanies large voice coil excursions. On the other hand, the copper cap requires a wider voice-coil gap, with increased magnetic reluctance; this reduces available flux, requiring a larger magnet for equivalent performance.
Electromagnets were often used in musical instrument amplifiers cabinets well into the 1950s; there were economic savings in those using tube amplifiers as the field coil could, and usually did, do double duty as a power supply choke. Very few manufacturers still produce electrodynamic loudspeakers with electrically powered field coils, as was common in the earliest designs. |
synth_fc_402_rep23 | Positive | Carbon footprint | Calculation | Single | https://en.wikipedia.org/wiki/Aerosol | 19 | Dynamics regimes
The Knudsen number of the particle define three different dynamical regimes that govern the behaviour of an aerosol:
where λ {\displaystyle \lambda } is the mean free path of the suspending gas and d {\displaystyle d} is the diameter of the particle. For particles in the free molecular regime, K >> 1; particles small compared to the mean free path of the suspending gas. In this regime, particles interact with the suspending gas through a series of "ballistic" collisions with gas molecules. As such, they behave similarly to gas molecules, tending to follow streamlines and diffusing rapidly through Brownian motion. The mass flux equation in the free molecular regime is:
where a is the particle radius, P and P are the pressures far from the droplet and at the surface of the droplet respectively, k is the Boltzmann constant, T is the temperature, C is mean thermal velocity and α is mass accommodation coefficient. The derivation of this equation assumes constant pressure and constant diffusion coefficient.
Particles are in the continuum regime when K << 1. In this regime, the particles are big compared to the mean free path of the suspending gas, meaning that the suspending gas acts as a continuous fluid flowing round the particle. The molecular flux in this regime is:
where a is the radius of the particle A, M is the molecular mass of the particle A, D is the diffusion coefficient between particles A and B, R is the ideal gas constant, T is the temperature (in absolute units like kelvin), and P and P are the pressures at infinite and at the surface respectively.
The transition regime contains all the particles in between the free molecular and continuum regimes or K ≈ 1. The forces experienced by a particle are a complex combination of interactions with individual gas molecules and macroscopic interactions. The semi-empirical equation describing mass flux is:
where I is the mass flux in the continuum regime. This formula is called the Fuchs-Sutugin interpolation formula. These equations do not take into account the heat release effect. |

Even in Roman times, wealthy people spent their free time on the coast. They also built large villa complexes with bathing facilities (so-called maritime villas) in particularly beautiful locations. Excavations of Roman architecture can still be found today, for example on the Amalfi Coast near Naples and in Barcola in Trieste.
The development of the beach as a popular leisure resort from the mid-19th century was the first manifestation of what is now the global tourist industry. The first seaside resorts were opened in the 18th century for the aristocracy, who began to frequent the seaside as well as the then fashionable spa towns, for recreation and health. One of the earliest such seaside resorts, was Scarborough in Yorkshire during the 1720s; it had been a fashionable spa town since a stream of acidic water was discovered running from one of the cliffs to the south of the town in the 17th century. The first rolling bathing machines were introduced by 1735.
The opening of the resort in Brighton and its reception of royal patronage from King George IV, extended the seaside as a resort for health and pleasure to the much larger London market, and the beach became a centre for upper-class pleasure and frivolity. This trend was praised and artistically elevated by the new romantic ideal of the picturesque landscape; Jane Austen 's unfinished novel Sanditon is an example of that. Later, Queen Victoria 's long-standing patronage of the Isle of Wight and Ramsgate in Kent ensured that a seaside residence was considered as a highly fashionable possession for those wealthy enough to afford more than one home. |

An example of Mannerist architecture is the Villa Farnese at Caprarola, in the rugged countryside outside of Rome. The proliferation of engravers during the 16th century spread Mannerist styles more quickly than any previous styles.
Dense with ornament of "Roman" detailing, the display doorway at Colditz Castle exemplifies the northern style, characteristically applied as an isolated "set piece" against unpretentious vernacular walling.
From the late 1560s onwards, many buildings in Valletta, the new capital city of Malta, were designed by the architect Girolamo Cassar in the Mannerist style. Such buildings include St. John's Co-Cathedral, the Grandmaster's Palace and the seven original auberges. Many of Cassar's buildings were modified over the years, especially in the Baroque period. However, a few buildings, such as Auberge d'Aragon and the exterior of St. John's Co-Cathedral, retain most of Cassar's original Mannerist design.
While many architectural styles explore harmonious ideals, Mannerism wants to take style a step further and explores the aesthetics of hyperbole and exaggeration. Mannerism is notable for its intellectual sophistication as well as its artificial (as opposed to naturalistic) qualities. Mannerism favours compositional tension and instability rather than balance and clarity. The definition of Mannerism, and the phases within it, continues to be the subject of debate among art historians.
Northern or Antwerp Mannerism predates and is distinct from Italian Mannerism. Antwerp during its 16th-century boom produced a style that was the last phase of Early Netherlandish painting with Early Renaissance elements. Through Antwerp, Renaissance and Mannerist styles were widely introduced in England, Germany, and northern and eastern Europe in general. |

Cape Verde's notable economic growth and improvement in living conditions despite a lack of natural resources have garnered international recognition, with other countries and international organizations often providing development aid. Since 2007, the UN has classified it as a developing nation rather than a least developed country.
Cape Verde has few natural resources. Only five of the ten main islands (Santiago, Santo Antão, São Nicolau, Fogo, and Brava) normally support significant agricultural production, and over 90% of all food consumed in Cape Verde is imported. Mineral resources include salt, pozzolana (a volcanic rock used in cement production), and limestone. Its small number of wineries making Portuguese-style wines have traditionally focused on the domestic market, but have recently met with some international acclaim.
The economy of Cape Verde is service-oriented, with commerce, transport, and public services accounting for more than 70% of GDP. Although nearly 35% of the population lives in rural areas, agriculture and fishing contribute only about 9% of GDP. Light manufacturing accounts for most of the remainder. Fish and shellfish are plentiful, and small quantities are exported. Cape Verde has cold storage and freezing facilities and fish processing plants in Mindelo, Praia, and on Sal. Expatriate Cape Verdeans contribute an amount estimated at 20% of GDP to the domestic economy through remittances. Despite having few natural resources and being semi-desert, the country has the highest living standards in the region and has attracted thousands of immigrants of different nationalities.
Since 1991, the government has pursued market-oriented economic policies, including an open welcome to foreign investors and a far-reaching privatization programme. It established as top development priorities the promotion of a market economy and the private sector; the development of tourism, light manufacturing industries, and fisheries; and the development of transport, communications, and energy facilities. From 1994 to 2000 about $407 million in foreign investments were made or planned, of which 58% were in tourism, 17% in industry, 4% in infrastructure, and 21% in fisheries and services.
In 2011, a wind farm was built on four islands that supplies about 30% of the electricity of the country. As host to the ECOWAS Regional Centre for Renewable Energy and Energy Efficiency, inaugurated in 2010, Cape Verde plans to lead by example by becoming entirely reliant on renewable energy sources by 2025. This policy is consistent with the host of documents adopted in 2015 paving the way to more sustainable development, including Cape Verde's Transformational Agenda to 2030, its National Renewable Energy Plan and its Low Carbon and Climate-resilient Development Strategy. Two years later, these were followed by a Strategic Plan for Sustainable Development, 2017–2021.
Between 2000 and 2009, real GDP increased on average by over 7% a year, well above the average for Sub-Saharan countries and faster than most small island economies in the region. Strong economic performance was bolstered by one of the fastest-growing tourism industries in the world, as well as by substantial capital inflows that allowed Cape Verde to build up national currency reserves to the current 3.5 months of imports. Unemployment has been falling rapidly, and the country is on track to achieve most of the UN Millennium Development Goals – including halving its 1990 poverty level.
In 2007, Cape Verde joined the World Trade Organization (WTO) and in 2008 the country graduated from Least Developed Country (LDC) to Middle Income Country (MIC) status.
Cape Verde has significant cooperation with Portugal at every level of the economy, which has led it to link its currency first to the Portuguese escudo and, in 1999, to the euro. On 23 June 2008 Cape Verde became the 153rd member of the WTO.
In early January 2018, the government announced that the minimum wage would be raised to 13,000 CVE (€118) per month, from 11,000 CVE, which was effective in mid-January 2018. |

With a growing and important metropolitan area, Greater Rosario has an estimated population of 1,750,000 as of 2020. One of its main attractions includes the neoclassical, Art Nouveau, and Art Deco architecture that has been preserved in hundreds of residences, houses and public buildings. The city is also famous for being the birthplace of the legendary Argentine footballer Lionel Messi.
Rosario is the head city of the Rosario Department and is located at the heart of the major industrial corridor in Argentina. The city is a major railroad terminal and the shipping center for north-eastern Argentina. Ships reach the city via the Paraná River, which allows the existence of a 10-metre-deep (34 ft) port. The Port of Rosario is subject to silting and must be dredged periodically. Exports include wheat, flour, hay, linseed and other vegetable oils, corn, sugar, lumber, meat, hides, and wool. Manufactured goods include flour, sugar, meat products, and other foodstuffs. The Rosario-Victoria Bridge, opened in 2004, spans the Paraná River, connecting Rosario with the city of Victoria, across the Paraná Delta. The city plays a critical role in agricultural commerce, and thus finds itself at the center of a continuing debate over taxes levied on big-ticket agricultural goods such as soy.
Along with Paraná, Rosario is one of the few Argentine cities that cannot point to a particular individual as its founder. The city's patron is the " Virgin of the Rosary ", whose feast day is 7 October. |

It is where all the planning takes place before the camera rolls and sets the overall vision of the project. The production company is created and a production office established. The film is pre-visualized by the director and may be storyboarded with the help of illustrators and concept artists. A production budget is drawn up to plan expenditures for the film. For major productions, insurance is procured to protect against accidents. Pre-production also includes working out the shoot location and casting process. The Producer hires a Line Manager or a Production Manager to create the schedule and budget for the film.
The nature of the film, and the budget, determine the size and type of crew used during filmmaking. Many Hollywood blockbusters employ a cast and crew of hundreds, while a low-budget, independent film may be made by a "skeleton crew" of eight or nine (or fewer). These are typical crew positions: |

Functional abilities, independence and quality of life issues are of great concern to geriatricians and their patients. Elderly people generally want to live independently as long as possible, which requires them to be able to engage in self-care and other activities of daily living. A geriatrician may be able to provide information about elder care options, and refers people to home care services, skilled nursing facilities, assisted living facilities, and hospice as appropriate.
Frail elderly people may choose to decline some kinds of medical care, because the risk-benefit ratio is different. For example, frail elderly women routinely stop screening mammograms, because breast cancer is typically a slowly growing disease that would cause them no pain, impairment, or loss of life before they would die of other causes. Frail people are also at significant risk of post-surgical complications and the need for extended care, and an accurate prediction—based on validated measures, rather than how old the patient's face looks—can help older patients make fully informed choices about their options. Assessment of older patients before elective surgeries can accurately predict the patients' recovery trajectories. One frailty scale uses five items: unintentional weight loss, muscle weakness, exhaustion, low physical activity, and slowed walking speed. A healthy person scores 0; a very frail person scores 5. Compared to non-frail elderly people, people with intermediate frailty scores (2 or 3) are twice as likely to have post-surgical complications, spend 50% more time in the hospital, and are three times as likely to be discharged to a skilled nursing facility instead of to their own homes. Frail elderly patients (score of 4 or 5) who were living at home before the surgery have even worse outcomes, with the risk of being discharged to a nursing home rising to twenty times the rate for non-frail elderly people. |

Early Western religious music often features parallel perfect intervals; these intervals would preserve the clarity of the original plainsong. These works were created and performed in cathedrals, and made use of the resonant modes of their respective cathedrals to create harmonies. As polyphony developed, however, the use of parallel intervals was slowly replaced by the English style of consonance that used thirds and sixths. The English style was considered to have a sweeter sound, and was better suited to polyphony in that it offered greater linear flexibility in part-writing. |

The earliest methods for solving quadratic equations were geometric. Babylonian cuneiform tablets contain problems reducible to solving quadratic equations. The Egyptian Berlin Papyrus, dating back to the Middle Kingdom (2050 BC to 1650 BC), contains the solution to a two-term quadratic equation.
The Greek mathematician Euclid (circa 300 BC) used geometric methods to solve quadratic equations in Book 2 of his Elements, an influential mathematical treatise Rules for quadratic equations appear in the Chinese The Nine Chapters on the Mathematical Art circa 200 BC. In his work Arithmetica, the Greek mathematician Diophantus (circa 250 AD) solved quadratic equations with a method more recognizably algebraic than the geometric algebra of Euclid. His solution gives only one root, even when both roots are positive.
The Indian mathematician Brahmagupta included a generic method for finding one root of a quadratic equation in his treatise Brāhmasphuṭasiddhānta (circa 628 AD), written out in words in the style of the time but more or less equivalent to the modern symbolic formula. His solution of the quadratic equation a x 2 + b x = c {\displaystyle \textstyle ax^{2}+bx=c} was as follows: "To the absolute number multiplied by four times the square, add the square of the middle term; the square root of the same, less the middle term, being divided by twice the square is the value." In modern notation, this can be written x = (c ⋅ 4 a + b 2 − b) / 2 a {\displaystyle \textstyle x={\bigl (}{\sqrt {c\cdot 4a+b^{2}}}-b{\bigr)}{\big /}2a}. The Indian mathematician Śrīdhara (8th–9th century) came up with a similar algorithm for solving quadratic equations in a now-lost work on algebra quoted by Bhāskara II. The modern quadratic formula is sometimes called Sridharacharya's formula in India.
The 9th-century Persian mathematician Muḥammad ibn Mūsā al-Khwārizmī solved quadratic equations algebraically. The quadratic formula covering all cases was first obtained by Simon Stevin in 1594. In 1637 René Descartes published La Géométrie containing special cases of the quadratic formula in the form we know today. |

synth_fc_3869_rep11 | Positive | Weather & Air quality | Database search | Single | https://en.wikipedia.org/wiki/Air_conditioning | 18 | Heating
Some air conditioning systems can reverse the refrigeration cycle and act as an air source heat pump, thus heating instead of cooling the indoor environment. They are also commonly referred to as "reverse cycle air conditioners". The heat pump is significantly more energy-efficient than electric resistance heating, because it moves energy from air or groundwater to the heated space and the heat from purchased electrical energy. When the heat pump is in heating mode, the indoor evaporator coil switches roles and becomes the condenser coil, producing heat. The outdoor condenser unit also switches roles to serve as the evaporator and discharges cold air (colder than the ambient outdoor air).
Most air source heat pumps become less efficient in outdoor temperatures lower than 4 °C or 40 °F. This is partly because ice forms on the outdoor unit's heat exchanger coil, which blocks air flow over the coil. To compensate for this, the heat pump system must temporarily switch back into the regular air conditioning mode to switch the outdoor evaporator coil back to the condenser coil, to heat up and defrost. Therefore, some heat pump systems will have electric resistance heating in the indoor air path that is activated only in this mode to compensate for the temporary indoor air cooling, which would otherwise be uncomfortable in the winter.
Newer models have improved cold-weather performance, with efficient heating capacity down to −14 °F (−26 °C). However, there is always a chance that the humidity that condenses on the heat exchanger of the outdoor unit could freeze, even in models that have improved cold-weather performance, requiring a defrosting cycle to be performed.
The icing problem becomes much more severe with lower outdoor temperatures, so heat pumps are sometimes installed in tandem with a more conventional form of heating, such as an electrical heater, a natural gas, heating oil, or wood-burning fireplace or central heating, which is used instead of or in addition to the heat pump during harsher winter temperatures. In this case, the heat pump is used efficiently during milder temperatures, and the system is switched to the conventional heat source when the outdoor temperature is lower. |

Belém is the major city and port at the mouth of the river at the Atlantic Ocean. The definition of where exactly the mouth of the Amazon is located, and how wide it is, is a matter of dispute, because of the area's peculiar geography. The Pará and the Amazon are connected by a series of river channels called furos near the town of Breves; between them lies Marajó, the world's largest combined river/sea island.
If the Pará river and the Marajó island ocean frontage are included, the Amazon estuary is some 325 km (202 mi) wide. In this case, the width of the mouth of the river is usually measured from Cabo Norte, the cape located straight east of Pracuúba in the Brazilian state of Amapá, to Ponta da Tijoca near the town of Curuçá, in the state of Pará.
A more conservative measurement excluding the Pará river estuary, from the mouth of the Araguari River to Ponta do Navio on the northern coast of Marajó, would still give the mouth of the Amazon a width of over 180 km (112 mi). If only the river's main channel is considered, between the islands of Curuá (state of Amapá) and Jurupari (state of Pará), the width falls to about 15 km (9.3 mi).
The plume generated by the river's discharge covers up to 1.3 million km and is responsible for muddy bottoms influencing a wide area of the tropical north Atlantic in terms of salinity, pH, light penetration, and sedimentation. |
synth_fc_2736_rep16 | Positive | Physics & Chemistry | Database creation | Multi | https://en.wikipedia.org/wiki/Ludwig_Wittgenstein | 8 | Engineering at Berlin and Manchester
He began his studies in mechanical engineering at the Technische Hochschule Berlin in Charlottenburg, Berlin, on 23 October 1906, lodging with the family of professor Dr. Jolles. He attended for three semesters, and was awarded a diploma (Abgangzeugnis) on 5 May 1908.
During his time at the Institute, Wittgenstein developed an interest in aeronautics. He arrived at the Victoria University of Manchester in the spring of 1908 to study for a doctorate, full of plans for aeronautical projects, including designing and flying his own plane. He conducted research into the behavior of kites in the upper atmosphere, experimenting at a meteorological observation site near Glossop in Derbyshire. Specifically, the Royal Meteorological Society researched and investigated the ionization of the upper atmosphere, by suspending instruments on balloons or kites. At Glossop, Wittgenstein worked under Professor of Physics Sir Arthur Schuster.
He also worked on the design of a propeller with small jet (Tip jet) engines on the end of its blades, something he patented in 1911, and that earned him a research studentship from the university in the autumn of 1908. At the time, contemporary propeller designs were not advanced enough to actually put Wittgenstein's ideas into practice, and it would be years before a blade design that could support Wittgenstein's innovative design was created. Wittgenstein's design required air and gas to be forced along the propeller arms to combustion chambers on the end of each blade, where they were then compressed by the centrifugal force exerted by the revolving arms and ignited. Propellers of the time were typically wood, whereas modern blades are made from pressed steel laminates as separate halves, which are then welded together. This gives the blade a hollow interior and thereby creates an ideal pathway for the air and gas.
Work on the jet-powered propeller proved frustrating for Wittgenstein, who had very little experience working with machinery. Jim Bamber, a British engineer who was his friend and classmate at the time, reported that
when things went wrong, which often occurred, he would throw his arms around, stomp about, and swear volubly in German.
According to William Eccles, another friend from that period, Wittgenstein then turned to more theoretical work, focusing on the design of the propeller – a problem that required relatively sophisticated mathematics. It was at this time that he became interested in the foundations of mathematics, particularly after reading Bertrand Russell 's The Principles of Mathematics (1903), and Gottlob Frege 's The Foundations of Arithmetic, vol. 1 (1893) and vol. 2 (1903). Wittgenstein's sister Hermine said he became obsessed with mathematics as a result, and was anyway losing interest in aeronautics. He decided instead that he needed to study logic and the foundations of mathematics, describing himself as in a "constant, indescribable, almost pathological state of agitation." In the summer of 1911 he visited Frege at the University of Jena to show him some philosophy of mathematics and logic he had written, and to ask whether it was worth pursuing. He wrote:
I was shown into Frege's study. Frege was a small, neat man with a pointed beard who bounced around the room as he talked. He absolutely wiped the floor with me, and I felt very depressed; but at the end he said 'You must come again', so I cheered up. I had several discussions with him after that. Frege would never talk about anything but logic and mathematics, if I started on some other subject, he would say something polite and then plunge back into logic and mathematics. |

The strings may be sounded by drawing the hair of the bow held by the right hand across them (arco) or by plucking them (pizzicato) most often with the right hand. In some cases, the violinist will pluck strings with the left hand. This is done to facilitate transitions from pizzicato to arco playing. It is also used in some virtuoso showpieces. Left hand pizzicato is usually done on open strings. Pizzicato is used on all of the violin family instruments; however, the systematic study of advanced pizzicato techniques is most developed in jazz bass, a style in which the instrument is almost exclusively plucked.
The right arm, hand, and bow and the bow speed are responsible for tone quality, rhythm, dynamics, articulation, and most (but not all) changes in timbre. The player draws the bow over the string, causing the string to vibrate and produce a sustained tone. The bow is a wooden stick with tensioned horsetail hair, which has been rosined with a bar of rosin. The natural texture of the horsehair and the stickiness of the rosin help the bow to "grip" the string, and thus when the bow is drawn over the string, the bow causes the string to sound a pitch.
Bowing can be used to produce long sustained notes or melodies. With a string section, if the players in a section change their bows at different times, a note can seem to be endlessly sustainable. As well, the bow can be used to play short, crisp little notes, such as repeated notes, scales and arpeggios, which provide a propulsive rhythm in many styles of music. |

Atlanta has played a major or contributing role in the development of various genres of American music at different points in the city's history. Beginning as early as the 1920s, Atlanta emerged as a center for country music, which was brought to the city by migrants from Appalachia. During the countercultural 1960s, Atlanta hosted the Atlanta International Pop Festival, with the 1969 festival taking place more than a month before Woodstock and featuring many of the same bands. The city was also a center for Southern rock during its 1970s heyday: the Allman Brothers Band 's hit instrumental " Hot 'Lanta " is an ode to the city, while Lynyrd Skynyrd 's famous live rendition of " Free Bird " was recorded at the Fox Theatre in 1976, with lead singer Ronnie Van Zant directing the band to "play it pretty for Atlanta". During the 1980s, Atlanta had an active punk rock scene centered on two of the city's music venues, 688 Club and the Metroplex, and Atlanta famously played host to the Sex Pistols ' first U.S. show, which was performed at the Great Southeastern Music Hall. The 1990s saw the city produce major mainstream acts across many different musical genres. Country music artist Travis Tritt, and R&B sensations Xscape, TLC, Usher and Toni Braxton, were just some of the musicians who call Atlanta home. The city also gave birth to Atlanta hip hop, a sub-genre that gained relevance and success with the introduction of the home-grown Atlantans known as Outkast, along with other Dungeon Family artists such as Organized Noize and Goodie Mob; however, it was not until the 2000s that Atlanta moved "from the margins to becoming hip-hop's center of gravity with another sub-genre called Crunk, part of a larger shift in hip-hop innovation to the South and East". In the 2000s, Atlanta was recognized by the Brooklyn-based Vice magazine for its indie rock scene, which revolves around the various live music venues found on the city's alternative eastside. To facilitate further local development, the state government provides qualified businesses and productions a 15% transferable income tax credit for in-state costs of music investments. |
synth_fc_1181_rep2 | Positive | Finance | Calculation | Single | https://en.wikipedia.org/wiki/Credit_card | 39 | Security
Credit card security relies on the physical security of the plastic card as well as the privacy of the credit card number. Therefore, whenever a person other than the card owner has access to the card or its number, security is potentially compromised. Once, merchants would often accept credit card numbers without additional verification for mail order purchases. It is now common practice to only ship to confirmed addresses as a security measure to minimize fraudulent purchases. Some merchants will accept a credit card number for in-store purchases, whereupon access to the number allows easy fraud, but many require the card itself to be present and require a signature (for magnetic stripe cards). A lost or stolen card can be cancelled, and if this is done quickly, will greatly limit the fraud that can take place in this way. European banks can require a cardholder's security PIN be entered for in-person purchases with the card.
The Payment Card Industry Data Security Standard (PCI DSS) is the security standard issued by the Payment Card Industry Security Standards Council (PCI SSC). This data security standard is used by acquiring banks to impose cardholder data security measures upon their merchants.
The goal of the credit card companies is not to eliminate fraud, but to "reduce it to manageable levels". This implies that fraud prevention measures will be used only if their cost is lower than the potential gains from fraud reduction, whereas high-cost low-return measures will not be used – as would be expected from organizations whose goal is profit maximization.
Internet fraud may be committed by claiming a chargeback which is not justified (" friendly fraud "), or carried out by the use of credit card information which can be stolen in many ways, the simplest being copying information from retailers, either online or offline. Despite efforts to improve security for remote purchases using credit cards, security breaches are usually the result of poor practice by merchants. For example, a website that safely uses TLS to encrypt card data from a client may then email the data, unencrypted, from the webserver to the merchant; or the merchant may store unencrypted details in a way that allows them to be accessed over the Internet or by a rogue employee; unencrypted card details are always a security risk. Even encrypted data may be cracked.
Controlled payment numbers (also known as virtual credit cards or disposable credit cards) are another option for protecting against credit card fraud where the presentation of a physical card is not required, as in telephone and online purchasing. These are one-time use numbers that function as a payment card and are linked to the user's real account, but do not reveal details, and cannot be used for subsequent unauthorized transactions. They can be valid for a relatively short time, and limited to the actual amount of the purchase or a limit set by the user. Their use can be limited to one merchant. If the number given to the merchant is compromised, it will be rejected if an attempt is made to use it a second time.
A similar system of controls can be used on physical cards. Technology provides the option for banks to support many other controls too that can be turned on and off and varied by the credit card owner in real time as circumstances change (i.e., they can change temporal, numerical, geographical and many other parameters on their primary and subsidiary cards). Apart from the obvious benefits of such controls: from a security perspective this means that a customer can have a Chip and PIN card secured for the real world, and limited for use in the home country. In this eventuality, a thief stealing the details will be prevented from using these overseas in non-chip and pin EMV countries. Similarly, the real card can be restricted from use online so that stolen details will be declined if this is tried. Then when card users shop online they can use virtual account numbers. In both circumstances, an alert system can be built in notifying a user that a fraudulent attempt has been made which breaches their parameters, and can provide data on this in real-time.
Additionally, there are security features present on the physical card itself in order to prevent counterfeiting. For example, most modern credit cards have a watermark that will fluoresce under ultraviolet light. Most major credit cards have a hologram. A Visa card has a letter V superimposed over the regular Visa logo and a MasterCard has the letters MC across the front of the card. Older Visa cards have a bald eagle or dove across the front while older MasterCard cards have two circles (Venn diagram) with continents on it. In the aforementioned cases, the security features are only visible under ultraviolet light and are invisible in normal light.
In the United States, the United States Department of Justice, United States Secret Service, Federal Bureau of Investigation, U.S. Immigration and Customs Enforcement, and U.S. Postal Inspection Service are responsible for prosecuting criminals who engage in credit card fraud. However, they do not have the resources to pursue all criminals, and in general they only prosecute cases exceeding $5,000.
Three improvements to card security have been introduced to the more common credit card networks, but none has proven to help reduce credit card fraud so far. First, the cards themselves are being replaced with similar-looking tamper-resistant smart cards which are intended to make forgery more difficult. The majority of smart card (IC card) based credit cards comply with the EMV (Europay MasterCard Visa) standard. Second, an additional 3 or 4 digit card security code (CSC) or card verification value (CVV) is now present on the back of most cards, for use in card not present transactions. Stakeholders at all levels in electronic payment have recognized the need to develop consistent global standards for security that account for and integrate both current and emerging security technologies. They have begun to address these needs through organisations such as PCI DSS and the Secure POS Vendor Alliance. |
synth_fc_96_rep26 | Positive | Biology | Calculation | Single | https://en.wikipedia.org/wiki/Perception | 18 | Evolutionary psychology
Many philosophers, such as Jerry Fodor, write that the purpose of perception is knowledge. However, evolutionary psychologists hold that the primary purpose of perception is to guide action. They give the example of depth perception, which seems to have evolved not to aid in knowing the distances to other objects but rather to aid movement. Evolutionary psychologists argue that animals ranging from fiddler crabs to humans use eyesight for collision avoidance, suggesting that vision is basically for directing action, not providing knowledge. Neuropsychologists showed that perception systems evolved along the specifics of animals' activities. This explains why bats and worms can perceive different frequency of auditory and visual systems than, for example, humans.
Building and maintaining sense organs is metabolically expensive. More than half the brain is devoted to processing sensory information, and the brain itself consumes roughly one-fourth of one's metabolic resources. Thus, such organs evolve only when they provide exceptional benefits to an organism's fitness.
Scientists who study perception and sensation have long understood the human senses as adaptations. Depth perception consists of processing over half a dozen visual cues, each of which is based on a regularity of the physical world. Vision evolved to respond to the narrow range of electromagnetic energy that is plentiful and that does not pass through objects. Sound waves provide useful information about the sources of and distances to objects, with larger animals making and hearing lower-frequency sounds and smaller animals making and hearing higher-frequency sounds. Taste and smell respond to chemicals in the environment that were significant for fitness in the environment of evolutionary adaptedness. The sense of touch is actually many senses, including pressure, heat, cold, tickle, and pain. Pain, while unpleasant, is adaptive. An important adaptation for senses is range shifting, by which the organism becomes temporarily more or less sensitive to sensation. For example, one's eyes automatically adjust to dim or bright ambient light. Sensory abilities of different organisms often co-evolve, as is the case with the hearing of echolocating bats and that of the moths that have evolved to respond to the sounds that the bats make.
Evolutionary psychologists claim that perception demonstrates the principle of modularity, with specialized mechanisms handling particular perception tasks. For example, people with damage to a particular part of the brain are not able to recognize faces (prosopagnosia). Evolutionary psychology suggests that this indicates a so-called face-reading module. |

Representations of the deity, such as statues (murti), paintings (thangka), or mandala, are often employed as an aid to visualization, in deity yoga. The use of visual aids, particularly microcosmic/macrocosmic diagrams, known as mandalas, is another unique feature of Buddhist Tantra. Mandalas are symbolic depictions of the sacred space of the awakened Buddhas and Bodhisattvas as well as of the inner workings of the human person. The macrocosmic symbolism of the mandala then, also represents the forces of the human body. The explanatory tantra of the Guhyasamaja tantra, the Vajramala, states: "The body becomes a palace, the hallowed basis of all the Buddhas."
Mandalas are also sacred enclosures, sacred architecture that house and contain the uncontainable essence of a central deity or yidam and their retinue. In the book The World of Tibetan Buddhism, the Dalai Lama describes mandalas thus: "This is the celestial mansion, the pure residence of the deity." The Five Tathagatas or 'Five Buddhas', along with the figure of the Adi-Buddha, are central to many Vajrayana mandalas as they represent the "five wisdoms", which are the five primary aspects of primordial wisdom or Buddha-nature.
All ritual in Vajrayana practice can be seen as aiding in this process of visualization and identification. The practitioner can use various hand implements such as a vajra, bell, hand-drum (damaru) or a ritual dagger (phurba), but also ritual hand gestures (mudras) can be made, special chanting techniques can be used, and in elaborate offering rituals or initiations, many more ritual implements and tools are used, each with an elaborate symbolic meaning to create a special environment for practice. Vajrayana has thus become a major inspiration in traditional Tibetan art. |

The scale ranges from Class 1, the darkest skies available on Earth, through to Class 9, inner-city skies. It gives several criteria for each level beyond naked-eye limiting magnitude (NELM). The accuracy and utility of the scale have been questioned in 2014 research. The table summarizes Bortle's descriptions of the classes.

After the death of Umar II, another son of Abd al-Malik, Yazid II (r. 720–724) became caliph. Not long after his accession, another mass revolt against Umayyad rule was staged in Iraq, this time by the prominent statesman Yazid ibn al-Muhallab. The latter declared a holy war against the Umayyads, took control of Basra and Wasit and gained the support of the Kufan elite. The caliph's Syrian army defeated the rebels and pursued and nearly eliminated the influential Muhallabids, marking the suppression of the last major Iraqi revolt against the Umayyads.
Yazid II reversed Umar II's equalization reforms, reimposing the jizya on the mawali, which sparked revolts in Khurasan in 721 or 722 that persisted for some twenty years and met strong resistance among the Berbers of Ifriqiya, where the Umayyad governor was assassinated by his discontented Berber guards. Warfare on the frontiers was also resumed, with renewed annual raids against the Byzantines and the Khazars in Transcaucasia. |
synth_fc_127_rep11 | Positive | Biology | Database removal | Multi | https://en.wikipedia.org/wiki/Bipartite_graph | 5 | Testing bipartiteness
It is possible to test whether a graph is bipartite, and to return either a two-coloring (if it is bipartite) or an odd cycle (if it is not) in linear time, using depth-first search. The main idea is to assign to each vertex the color that differs from the color of its parent in the depth-first search forest, assigning colors in a preorder traversal of the depth-first-search forest. This will necessarily provide a two-coloring of the spanning forest consisting of the edges connecting vertices to their parents, but it may not properly color some of the non-forest edges. In a depth-first search forest, one of the two endpoints of every non-forest edge is an ancestor of the other endpoint, and when the depth first search discovers an edge of this type it should check that these two vertices have different colors. If they do not, then the path in the forest from ancestor to descendant, together with the miscolored edge, form an odd cycle, which is returned from the algorithm together with the result that the graph is not bipartite. However, if the algorithm terminates without detecting an odd cycle of this type, then every edge must be properly colored, and the algorithm returns the coloring together with the result that the graph is bipartite.
Alternatively, a similar procedure may be used with breadth-first search in place of depth-first search. Again, each node is given the opposite color to its parent in the search forest, in breadth-first order. If, when a vertex is colored, there exists an edge connecting it to a previously-colored vertex with the same color, then this edge together with the paths in the breadth-first search forest connecting its two endpoints to their lowest common ancestor forms an odd cycle. If the algorithm terminates without finding an odd cycle in this way, then it must have found a proper coloring, and can safely conclude that the graph is bipartite.
For the intersection graphs of n {\displaystyle n} line segments or other simple shapes in the Euclidean plane, it is possible to test whether the graph is bipartite and return either a two-coloring or an odd cycle in time O (n log n) {\displaystyle O(n\log n)}, even though the graph itself may have up to O (n 2) {\displaystyle O\left(n^{2}\right)} edges. |
synth_fc_2710_rep27 | Positive | Music | Generation | Single | https://en.wikipedia.org/wiki/Kermit_the_Frog | 1 | Kermit the Frog is a Muppet character created in 1955 and originally performed by Jim Henson. Kermit is the pragmatic everyman protagonist of numerous Muppet productions, most notably as the showrunner and host of the sketch comedy television series The Muppet Show and a featured role on Sesame Street. He has appeared in other television series, feature films, specials, and public service announcements through the years. He also served as a mascot of The Jim Henson Company and appeared in various Henson projects until 2004. Kermit performed the hit singles "Bein' Green" in 1970 for Sesame Street and "Rainbow Connection" in 1979 for The Muppet Movie, the first feature-length film featuring the Muppets. Kermit's original performance of "Rainbow Connection" reached No. 25 on the Billboard Hot 100 and was added to the Library of Congress's National Recording Registry in 2021. Henson performed Kermit until his death in 1990, and then Steve Whitmire performed Kermit from that time until his dismissal in 2016; Kermit has been performed by Matt Vogel since 2017. He was also voiced by Frank Welker in Muppet Babies and occasionally in other animation projects, and is voiced by Matt Danner in the 2018 reboot of Muppet Babies. Kermit has remained as a recognizable character in popular culture worldwide for over half a century, starring in several television series and films, and receiving dozens of honors and awards by various organizations. In 2006, the character was credited as the author of Before You Leap: A Frog's Eye View of Life's Greatest Lessons, an "autobiography" told from the perspective of the character himself. |

Cavalry found a new role in colonial campaigns (irregular warfare), where modern weapons were lacking and the slow moving infantry-artillery train or fixed fortifications were often ineffective against indigenous insurgents (unless the latter offered a fight on an equal footing, as at Tel-el-Kebir, Omdurman, etc.). Cavalry " flying columns " proved effective, or at least cost-effective, in many campaigns—although an astute native commander (like Samori in western Africa, Shamil in the Caucasus, or any of the better Boer commanders) could turn the tables and use the greater mobility of their cavalry to offset their relative lack of firepower compared with European forces.
In 1903 the British Indian Army maintained forty regiments of cavalry, numbering about 25,000 Indian sowars (cavalrymen), with British and Indian officers.
Among the more famous regiments in the lineages of the modern Indian and Pakistani armies are:
Several of these formations are still active, though they now are armoured formations, for example the Guides Cavalry of Pakistan.
The French Army maintained substantial cavalry forces in Algeria and Morocco from 1830 until the end of the Second World War. Much of the Mediterranean coastal terrain was suitable for mounted action and there was a long established culture of horsemanship amongst the Arab and Berber inhabitants. The French forces included Spahis, Chasseurs d' Afrique, Foreign Legion cavalry and mounted Goumiers. Both Spain and Italy raised cavalry regiments from amongst the indigenous horsemen of their North African territories (see regulares, Italian Spahis and savari respectively).
Imperial Germany employed mounted formations in South West Africa as part of the Schutztruppen (colonial army) garrisoning the territory. |
synth_fc_240_rep1 | Positive | Biomass | Calculation | Multi | https://en.wikipedia.org/wiki/Cyprinodontiformes | 2 | Description
Some members of this order are notable for inhabiting extreme environments, such as saline or very warm waters, heavily polluted waters, rain water pools devoid of minerals and made acidic by decaying vegetation, or isolated situations where no other types of fish occur.
They are typically carnivores, and often live near the surface, where the oxygen-rich water compensates for environmental disadvantages. Scheel (1968) observed the gut contents were invariably ants, others have reported insects, worms and aquatic crustaceans. Aquarium specimens are invariably seen eating protozoans from the water column and the surfaces of leaves, however these are not apparent as stomach contents. Many members of the family Cyprinodontidae (the pupfishes) eat plant material as well and some have adapted to a diet very high in algae to the point where one, the American Flag Fish, is a renowned algae eater in the aquarium, in spite of belonging to an order of fishes that do not generally consume any plant material. In addition, killifish derive some of the carotenoids and other chemicals required to make their body pigments from pollen grains on the surface of and in the gut of insects they eat from the surface of the water; this can be simulated in culture by the use of special color enhancing foods that contain these compounds.
Although the Cyprinodontiformes are a diverse group, most species contained within are small to medium-sized fish, with small mouths, large eyes, a single dorsal fin, and a rounded caudal fin. The largest species is the cuatro ojos (Anableps dowei), which measures 34 cm (13 in) in length, while the smallest, the least killifish (Heterandria formosa), is just 8 mm (0.31 in) long as an adult. |
synth_fc_1759_rep12 | Positive | Health | Calculation | Single | https://en.wikipedia.org/wiki/Likelihood_function | 17 | Likelihood region
A likelihood region is the set of all values of θ whose relative likelihood is greater than or equal to a given threshold. In terms of percentages, a p % likelihood region for θ is defined to be
{ θ: R (θ) ≥ p 100 }. {\displaystyle \left\{\theta:R(\theta)\geq {\frac {p}{100}}\right\}.}
If θ is a single real parameter, a p % likelihood region will usually comprise an interval of real values. If the region does comprise an interval, then it is called a likelihood interval.
Likelihood intervals, and more generally likelihood regions, are used for interval estimation within likelihoodist statistics: they are similar to confidence intervals in frequentist statistics and credible intervals in Bayesian statistics. Likelihood intervals are interpreted directly in terms of relative likelihood, not in terms of coverage probability (frequentism) or posterior probability (Bayesianism).
Given a model, likelihood intervals can be compared to confidence intervals. If θ is a single real parameter, then under certain conditions, a 14.65% likelihood interval (about 1:7 likelihood) for θ will be the same as a 95% confidence interval (19/20 coverage probability). In a slightly different formulation suited to the use of log-likelihoods (see Wilks' theorem), the test statistic is twice the difference in log-likelihoods and the probability distribution of the test statistic is approximately a chi-squared distribution with degrees-of-freedom (df) equal to the difference in df's between the two models (therefore, the e likelihood interval is the same as the 0.954 confidence interval; assuming difference in df's to be 1). |
synth_fc_3773_rep29 | Positive | Weather & Air quality | Feature search | Single | https://en.wikipedia.org/wiki/Wildfire | 19 | Epidemiology
The Western US has seen an increase in both the frequency and intensity of wildfires over the last several decades. This has been attributed to the arid climate of there and the effects of global warming. An estimated 46 million people were exposed to wildfire smoke from 2004 to 2009 in the Western US. Evidence has demonstrated that wildfire smoke can increase levels of airborne particulate.
The EPA has defined acceptable concentrations of PM in the air, through the National Ambient Air Quality Standards and monitoring of ambient air quality has been mandated. Due to these monitoring programs and the incidence of several large wildfires near populated areas, epidemiological studies have been conducted and demonstrate an association between human health effects and an increase in fine particulate matter due to wildfire smoke.
An increase in PM smoke emitted from the Hayman fire in Colorado in June 2002, was associated with an increase in respiratory symptoms in patients with COPD. Looking at the wildfires in Southern California in 2003, investigators have shown an increase in hospital admissions due to asthma symptoms while being exposed to peak concentrations of PM in smoke. Another epidemiological study found a 7.2% (95% confidence interval: 0.25%, 15%) increase in risk of respiratory related hospital admissions during smoke wave days with high wildfire-specific particulate matter 2.5 compared to matched non-smoke-wave days.
Children participating in the Children's Health Study were also found to have an increase in eye and respiratory symptoms, medication use and physician visits. Mothers who were pregnant during the fires gave birth to babies with a slightly reduced average birth weight compared to those who were not exposed. Suggesting that pregnant women may also be at greater risk to adverse effects from wildfire. Worldwide, it is estimated that 339,000 people die due to the effects of wildfire smoke each year.
Besides the size of PM, their chemical composition should also be considered. Antecedent studies have demonstrated that the chemical composition of PM from wildfire smoke can yield different estimates of human health outcomes as compared to other sources of smoke such as solid fuels. |
