[Q]: Context: A stepper is a device used in the manufacture of integrated circuits (ICs) that is similar in operation to a slide projector or a photographic enlarger. Steppers are an essential part of the complex process, called photolithography, that creates millions of microscopic circuit elements on the surface of tiny chips of silicon. These chips form the heart of ICs such as computer processors, memory chips, and many other devices., Pentax () is a brand name used primarily by Ricoh Imaging Company for cameras, sport optics (including binoculars and rifle scopes), and CCTV optics. The brand is also used by Hoya Corporation for medical products & services, TI Asahi for surveying instruments, and Seiko Optical Products for certain optical lenses., A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically., The Nikon F camera, introduced in April 1959, was Nikon's first SLR camera. It was one of the most advanced cameras of its day. Although many of the concepts had already been introduced elsewhere, it was revolutionary in that it was the first to combine them all in one camera. It was produced until October 1973 and was replaced by the quite similar Nikon F2. Aspects of its design remain in all of Nikon's subsequent SLR cameras, through the current Nikon F6 film and Nikon D5 digital models (which still share its Nikon F-mount for lenses). The "F" in Nikon F was selected by Nippon Kogaku from the letter F of the name of the designer of the bayonet mount, Mr. Fuketa. That tradition was carried all the way through their top line of Nikon cameras until the introduction of the Nikon D1 (digital) cameras decades later., Large format refers to any imaging format of 4×5 inches (102×127 mm) or larger. Large format is larger than "medium format", the 6×6 cm (2×2 inch) or 6×9 cm (2×3 inch) size of Hasselblad, Rollei, Kowa, and Pentax cameras (using 120- and 220-roll film), and much larger than the 24×36 mm (~ 1.0x1.5 inch) frame of 35 mm format.
The main advantage of large format, film or digital, is higher resolution at the same pixel pitch, or same resolution with more larger pixels or grain. A 4×5 inch image has about 16 times the area, and thus 16× the total resolution, of a 35 mm frame., 35 mm film (millimeter) is the film gauge most commonly used for motion pictures and chemical still photography (see 135 film). The name of the gauge refers to the width of the photographic film, which consists of strips 34.98 ±0.03 mm (1.377 ±0.001 inches) wide. The standard negative pulldown for movies ("single-frame" format) is four perforations per frame along both edges, which results in 16 frames per foot of film. For still photography, the standard frame has eight perforations on each side., A microscope (from the , "mikrós", "small" and , "skopeîn", "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope., , formerly known as , is a Japanese multinational electronics corporation headquartered in Kadoma, Osaka, Japan., Nikonos Calypso is the name of a series of 35mm format cameras specifically designed for underwater photography launched by Nikon in 1963. The early Nikonos cameras were improvements of the Calypso camera, which was an original design by Jacques-Yves Cousteau and Belgian engineer Jean de Wouters, Binoculars or field glasses are binocular telescopes mounted side-by-side and aligned to point in the same direction, allowing the viewer to use both eyes (binocular vision) when viewing distant objects. Most are sized to be held using both hands, although sizes vary widely from opera glasses to large pedestal mounted military models., Sony Corporation is the electronics business unit and the parent company of the Sony Group, which is engaged in business through its four operating components  electronics (video games, network services and medical business), motion pictures, music and financial services. These make Sony one of the most comprehensive entertainment companies in the world. Sony's principal business operations include Sony Corporation, Sony Pictures Entertainment, Sony Interactive Entertainment, Sony Music Entertainment, Sony Mobile (formerly Sony Ericsson) and Sony Financial. Sony is among the Semiconductor sales leaders by year and as of 2013, the fourth-largest television manufacturer in the world, after Samsung Electronics, LG Electronics and TCL., Its products include cameras, camera lenses, binoculars, microscopes, ophthalmic lenses, measurement instruments, rifle scopes, spotting scopes, and the steppers used in the photolithography steps of semiconductor fabrication, of which it is the world's second largest manufacturer. The companies held by Nikon form the Nikon Group. Among its products are Nikkor imaging lenses (for F-mount cameras, large format photography, photographic enlargers, and other applications), the Nikon F-series of 35 mm film SLR cameras, the Nikon D-series of digital SLR cameras, the Coolpix series of compact digital cameras, and the Nikonos series of underwater film cameras. Nikon's main competitors in camera and lens manufacturing include Canon, Sony, Fujifilm, Panasonic, Pentax, and Olympus., , better known as Fujifilm or simply Fuji, stylized as FUJiFILM, is a Japanese multinational photography and imaging company headquartered in Tokyo., Photolithography, also termed optical lithography or UV lithography, is a process used in microfabrication to pattern parts of a thin film or the bulk of a substrate. It uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical "photoresist", or simply "resist," on the substrate. A series of chemical treatments then either engraves the exposure pattern into, or enables deposition of a new material in the desired pattern upon, the material underneath the photo resist. For example, in complex integrated circuits, a modern CMOS wafer will go through the photolithographic cycle up to 50 times., Nikkor is the brand of lenses produced by Nikon Corporation, including camera lenses for the Nikon F-mount., The 70 - 300mm lens is a telephoto zoom lens made by Nikon . The lens has an F - mount to work with all the SLRs line of cameras ( except the early 70 - 300G with the D40 ) . The lens comes in four different versions : AF f / 4 - 5.6G AF f / 4 - 5.6D AF f / 4 - 5.6D ED AF - S f / 4.5 - 5.6G IF - ED It is the successor of the 70 - 210 lens , which targets the prosumer market , one grade lower than 80 - 200mm with large aperture . Introduced in August 2006 , the current incarnation of the lens ( AF - S VR f / 4.5 - 5.6G IF - ED ) improves on the original with VR stabilization technology as well as with internally focusing components ( IF ) . More expensive than its partner 55 - 200mm lens , its construction is similar , with the exterior shell being fabricated from plastic components . It also shares a similarly stiff zoom ring with the 55 - 200mm , although a side benefit of this is that zoom creep is eliminated . Unlike the 55 - 200 , the 70 - 300mm lens is full - frame . Also , the longer barrel length allowed the focus ring to be relocated in front of the zoom ring , making manual focus operations simpler ., Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events. The scope and application of a measurement is dependent on the context and discipline. In the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the "International vocabulary of metrology" published by the International Bureau of Weights and Measures. However, in other fields such as statistics as well as the social and behavioral sciences, measurements can have multiple levels, which would include nominal, ordinal, interval, and ratio scales., Subject: nikon f 70-300mm lens, Relation: instance_of, Options: (A) application (B) april (C) area (D) brand (E) camera (F) camera lens (G) canon (H) chemical (I) company (J) complex (K) computer (L) corporation (M) day (N) device (O) eight (P) electronics (Q) event (R) field (S) film (T) format (U) four (V) instrument (W) letter (X) line (Y) lithography (Z) manufacturer ([) manufacturing (\) material (]) measurement (^) microscope (_) motion (`) name (a) negative (b) network (c) object (d) october (e) operation (f) parent company (g) part (h) pattern (i) photography (j) point (k) process (l) revolutionary (m) rifle (n) series (o) side (p) single (q) size (r) statistics

He has been featured artist and adjudicator for Music Teachers National Association , Ohio and Kentucky chapters , featured artist at the NKU Summer Piano Institute since 1997 , and Visiting Artist at the Pedagogical University of Lugansk , Ukraine ., The Dnieper River or (also known as: "Dnepr", "Dnyapro" or "Dnipro") is one of the major rivers of Europe (fourth by length), rising near Smolensk, Russia and flowing through Russia, Belarus and Ukraine to the Black Sea. It is the longest river of Ukraine and Belarus and the fourth longest river in Europe. 
The total length ranges between and with a drainage basin of .
The river is noted for its dams and hydroelectric stations. The Dnieper is an important navigable waterway for the economy of Ukraine and is connected via the DnieperBug Canal to other waterways in Europe., Vladimir Samoylovich Horowitz (November 5, 1989) was a Russian-born American classical pianist and composer. He was acclaimed for his virtuoso technique, his tone color, and the excitement engendered by his playing. He is recognized as one of the greatest pianists of all time., A pianist is an individual musician who plays the piano. Most forms of Western music can make use of the piano. Consequently, pianists have a wide variety of repertoire and styles to choose from, including traditionally classical music, Jazz, blues and all sorts of popular music, including rock music. Most pianists can, to a certain extent, play other keyboard-related instruments such as the synthesizer, harpsichord, celesta and the organ and keyboard. Perhaps the greatest pianist of all time was Franz Liszt, whose piano mastery was described by Anton Rubinstein: "In comparison with Liszt, all other pianists are children". , Ukraine (tr. ) is a sovereign state in Eastern Europe, bordered by Russia to the east and northeast, Belarus to the northwest, Poland and Slovakia to the west, Hungary, Romania, and Moldova to the southwest, and the Black Sea and Sea of Azov to the south and southeast, respectively. Ukraine is currently in territorial dispute with Russia over the Crimean Peninsula which Russia annexed in 2014 but which Ukraine and most of the international community recognise as Ukrainian. Including Crimea, Ukraine has an area of , making it the largest country entirely within Europe and the 46th largest country in the world. It has a population of about 44.5 million, making it the 32nd most populous country in the world., Miami University (also referred to as Miami U, Miami of Ohio, Miami University, Ohio, or simply Miami) is a coeducational public research university located in Oxford, Ohio, United States. Founded in 1809, although classes were not held until 1824, it is the 10th oldest public university in the United States and the second oldest university in Ohio. In its 2017 edition, U.S. News & World Report ranked the university 79th among national universities, the 30th top public school, and 2nd (1st among public institutions) for best undergraduate teaching at national universities. , Kiev or Kyiv is the capital and largest city of Ukraine, located in the north central part of the country on the Dnieper River. The population in July 2015 was (though higher estimated numbers have been cited in the press), making Kiev the 7th most populous city in Europe., A university ("a whole", "a corporation") is an institution of higher (or tertiary) education and research which grants academic degrees in various subjects. 
Universities typically provide undergraduate education and postgraduate education., Northern Kentucky University is a public, co-educational university in northern Kentucky located in Highland Heights, seven miles (11 km) southeast of downtown Cincinnati, Ohio. The university is primarily an undergraduate, liberal arts institution, but it also features graduate programs. Total enrollment at the university currently exceeds 15,000 students, with over 13,000 undergraduate students and over 2,000 graduate students served by nearly 2600 faculty and staff. Northern Kentucky University is the third largest university, behind the University of Cincinnati and Miami University, but before Xavier University, of Greater Cincinnati's four large, four-year universities and the youngest of Kentucky's eight state universities, although it is not the last to join the state system, as the University of Louisville did not become a state university until 1970., Merited (Performing) Artist of Ukraine is a state honorary title of decoration awarded by the Ukrainian SSR and later Ukraine for outstanding achievement in the performing arts. It is regulated by the "Law of Ukraine Regarding the State Awards of Ukraine" (#1549-14)., The University of Cincinnati (commonly referred to as UC or Cincinnati) is a comprehensive public research university in Cincinnati, in the U.S. state of Ohio, and a part of the University System of Ohio., The University of Louisville (UofL) is a public university in Louisville, Kentucky, a member of the Kentucky state university system. When founded in 1798, it was the first city-owned public university in the United States and one of the first universities chartered west of the Allegheny Mountains. The university is mandated by the Kentucky General Assembly to be a "Preeminent Metropolitan Research University". UofL enrolls students from 118 of 120 Kentucky counties, all 50 U.S. states, and 116 countries around the world., Subject: sergei polusmiak, Relation: occupation, Options: (A) academic (B) artist (C) composer (D) faculty (E) harpsichord (F) major (G) member (H) musician (I) pianist (J) research (K) sovereign (L) ukraine

[Q]: Context: The Ohio River, which streams westward from Pittsburgh, Pennsylvania, to Cairo, Illinois, is the largest tributary, by volume, of the Mississippi River in the United States. At the confluence, the Ohio is considerably bigger than the Mississippi (Ohio at Cairo: 281,500 cu ft/s (7,960 m/s); Mississippi at Thebes: 208,200 cu ft/s (5,897 m/s)) and, thus, is hydrologically the main stream of the whole river system, including the Allegheny River further upstream., Cincinnati is a city in the U.S. state of Ohio that serves as county seat of Hamilton County. Settled in 1788, the city is located on the north side of the confluence of the Licking with the Ohio River. With a population of 298,550, Cincinnati is the third-largest city in Ohio and the 65th-largest city in the United States. Its metropolitan statistical area is the 28th-largest in the United States and the largest centered in Ohio. The city is also part of the larger CincinnatiMiddletownWilmington combined statistical area, which had a population of 2,172,191 in the 2010 census., In electromagnetics, directivity is a parameter of an antenna or optical system which measures the degree to which the radiation emitted is concentrated in a single direction. It measures the power density the antenna radiates in the direction of its strongest emission, versus the power density radiated by an ideal isotropic radiator (which emits uniformly in all directions) radiating the same total power., Kentucky, officially the Commonwealth of Kentucky, is a state located in the east south-central region of the United States. Kentucky is one of four U.S. states constituted as a commonwealth (the others being Virginia, Pennsylvania, and Massachusetts). Originally a part of Virginia, in 1792 Kentucky became the 15th state to join the Union. Kentucky is the 37th most extensive and the 26th most populous of the 50 United States., In electromagnetism, there are two kinds of dipoles:, In radio and telecommunications a dipole antenna or doublet is the simplest and most widely used class of antenna. The dipole is any one of a class of antennas producing a radiation pattern approximating that of an elementary electric dipole with a radiating structure supporting a line current so energized that the current has only one node at each end. The dipole antenna may be fed anywhere along its length, but commonly consists of two identical conductive elements such as metal wires or rods, which are usually bilaterally symmetrical. The driving current from the transmitter is applied, or for receiving antennas the output signal to the receiver is taken, between the two halves of the antenna. Each side of the feedline to the transmitter or receiver is connected to one of the conductors. This contrasts with a monopole antenna, which consists of a single rod or conductor with one side of the feedline connected to it, and the other side connected to some type of ground. A common example of a dipole is the "rabbit ears" television antenna found on broadcast television sets., A U.S. state is a constituent political entity of the United States of America. There are 50 states, which are bound together in a union with each other. Each state holds administrative jurisdiction over a defined geographic territory, and shares its sovereignty with the United States federal government. Due to the shared sovereignty between each state and the federal government, Americans are citizens of both the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons covered by certain types of court orders (e.g., paroled convicts and children of divorced spouses who are sharing custody)., A combined statistical area (CSA) is composed of adjacent metropolitan (MSA) and micropolitan statistical areas (µSA) in the United States and Puerto Rico that can demonstrate economic or social linkage. The United States Office of Management and Budget defines a CSA as consisting of various combinations of adjacent metropolitan and micropolitan areas with economic ties measured by commuting patterns. These areas that combine retain their own designations as metropolitan or micropolitan statistical areas within the larger combined statistical area., Downtown Cincinnati is the central business district of Cincinnati, Ohio, and one of its 52 neighborhoods., Erlanger is a city in Kenton County, Kentucky, United States. It had a 2010 census population of 18,368. Erlanger is part of the Cincinnati-Middletown, OH-KY-IN Metropolitan Statistical Area., A central business district (CBD) is the commercial and business centre of a city. In larger cities, it is often synonymous with the city's "financial district". Geographically, it often coincides with the "city centre" or "downtown", but the two concepts are separate: many cities have a central "business" district located away from its commercial or cultural city centre or downtown. Both the CBD and the city centre or downtown may also coincide with the central activities district., Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power transmitted from a theoretical half-wave dipole antenna. It is differentiated from effective (or equivalent) isotropic radiated power (EIRP) mainly by use of relative antenna gain instead of absolute gain in the calculation. In the case of ERP, antenna gain is calculated as compared to the maximum directivity of a half-wave dipole antenna, whereas EIRP is calculated using antenna gain referenced to an ideal isotropic radiator, otherwise known as "absolute" gain. The term "antenna gain" is assumed to be absolute (referenced to isotropic) unless specifically stated to be relative. The gain is then multiplied by the power actually accepted by the antenna to result in the actual ERP value (or EIRP). Power losses which occur prior to the antenna, e.g., in the transmission line or from inefficiency in the generator itself are therefore not included in the calculation of ERP or EIRP., In the United States, a metropolitan statistical area (MSA) is a geographical region with a relatively high population density at its core and close economic ties throughout the area. Such regions are neither legally incorporated as a city or town would be, nor are they legal administrative divisions like counties or separate entities such as states. As such, the precise definition of any given metropolitan area can vary with the source. A typical metropolitan area is centered on a single large city that wields substantial influence over the region (e.g., Chicago or Atlanta). However, some metropolitan areas contain more than one large city with no single municipality holding a substantially dominant position (e.g., DallasFort Worth metroplex, Norfolk-Virginia Beach (Hampton Roads), RiversideSan Bernardino (Inland Empire) or MinneapolisSaint Paul)., WIZF ( 101.1 FM ) A.K.A. `` 101.1 The Wiz '' is a Rhythmic Contemporary radio station licensed to Erlanger , Kentucky serving the Cincinnati area . The station plays an Hip - Hop , R&B , Pop , Reggae and Gospel hip - hop music . The station is owned and operated by Radio One . It broadcasts with an effective radiated power of 2500 watts . Its studios are located at Centennial Plaza in Downtown Cincinnati and the transmitter site is west of the downtown area . Prior to becoming WIZF in 1987 , this frequency held the call letters WHKK and had a religious format . On Friday July 14 , 2006 WIZF changed frequencies from 100.9 FM to 101.1 FM , but kept `` The Wiz '' as their iconic station 's nickname . WIZF is the official syndicated home to The Rickey Smiley Morning Show since 2016 . Pat Garrett has been the voice of WIZF since the station 's debut in 1987 all the way to 2015 . WIIZ The Wiz 97.9 in Augusta also goes by the name The Wiz and carries the Russ Parr Morning Show as well but is unrelated due to different ownerships The station was also home to Cincinnati native DJ Etrayn from 2012 - 2014 ., Ohio is an Eastern state in the Great Lakes region of the United States. Ohio is the 34th largest by area, the 7th most populous, and the 10th most densely populated of the 50 United States. The state's capital and largest city is Columbus., A county seat is an administrative center, seat of government, or capital city of a county or civil parish. The term is used in the United States, Canada, Romania, China and Taiwan. In the United Kingdom and Ireland, county towns have a similar function., A census is the procedure of systematically acquiring and recording information about the members of a given population. It is a regularly occurring and official count of a particular population. The term is used mostly in connection with national population and housing censuses; other common censuses include agriculture, business, and traffic censuses. The United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every 10 years. United Nations recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practice., Radio frequency (RF) is any of the electromagnetic wave frequencies that lie in the range extending from around to , which include those frequencies used for communications or radar signals. RF usually refers to
electrical rather than mechanical oscillations. However, mechanical RF systems do exist (see mechanical filter and RF MEMS)., Subject: wizf, Relation: located_in_the_administrative_territorial_entity, Options: (A) center (B) central (C) central region (D) centre (E) chicago (F) cincinnati (G) district (H) fort (I) fort worth (J) illinois (K) kenton county (L) kentucky (M) middletown (N) minneapolis (O) most (P) of (Q) ohio (R) paul (S) pennsylvania (T) river (U) romania (V) saint paul (W) san bernardino (X) south (Y) taiwan (Z) united states of america ([) virginia (\) wilmington
