Colombia ( () kə-LUM-bee-ə, -⁠LOM-; Spanish: [koˈlombja] ()), officially the Republic of Colombia (Spanish: ), is a sovereign state largely situated in the northwest of South America, with territories in Central America. Colombia shares a border to the northwest with Panama, to the east with Venezuela and Brazil and to the south with Ecuador and Peru. It shares its maritime limits with Costa Rica, Nicaragua, Honduras, Jamaica, Haiti, and the Dominican Republic. Colombia is a unitary, constitutional republic comprising thirty-two departments, with the capital in Bogota. Colombia has been inhabited by various indigenous peoples since 12,000 BCE, including the Muisca, Quimbaya, and the Tairona. The Spanish arrived in 1499 and by the mid-16th century conquered and colonized much of the region, establishing the New Kingdom of Granada, with Santafé de Bogotá as its capital. Independence from Spain was achieved in 1819, but by 1830 the "Gran Colombia" Federation was dissolved, with what is now Colombia and Panama emerging as the Republic of New Granada. The new nation experimented with federalism as the Granadine Confederation (1858), and then the United States of Colombia (1863), before the Republic of Colombia was finally declared in 1886. Panama seceded in 1903, leading to Colombia's present borders. Beginning in the 1960s, the country suffered from an asymmetric low-intensity armed conflict and rampant political violence, both of which escalated in the 1990s. Since 2005, there has been significant improvement in security, stability, and rule of law. Colombia is one of the most ethnically and linguistically diverse countries in the world, with its rich cultural heritage reflecting influences by indigenous peoples, European settlement, forced African migration, immigration from Europe and the Middle East. Urban centres are mostly located in the highlands of the Andes mountains and the Caribbean coast. Colombia is among the world's 17 megadiverse countries, and the most densely biodiverse per square kilometer; its territory encompasses Amazon rainforest, tropical grassland and coastlines along both the Caribbean and Pacific. Colombia is a middle power and regional actor in Latin America. It is part of the CIVETS group of six leading emerging markets and a member of the UN, the WTO, the OAS, the Pacific Alliance, and other international organizations. Colombia's diversified economy is the fourth largest in Latin America, with macroeconomic stability and favorable long-term growth prospects.

Damascus (; Arabic: دمشق‎, translit. Dimašq [diˈmaʃq], Syrian Arabic: [dɪˈmaʃʔ]) is the capital of the Syrian Arab Republic; it is also the country's largest city, following the decline in population of Aleppo due to the battle for the city. It is colloquially known in Syria as aš-Šām (الشام) and titled the "City of Jasmine" (مدينة الياسمين Madīnat al-Yāsmīn). In addition to being one of the oldest continuously inhabited cities in the world, Damascus is a major cultural center of the Levant and the Arab world. The city has an estimated population of 1,711,000 as of 2009. Located in south-western Syria, Damascus is the center of a large metropolitan area of 2.7 million people (2004). Geographically embedded on the eastern foothills of the Anti-Lebanon mountain range 80 kilometres (50 mi) inland from the eastern shore of the Mediterranean on a plateau 680 metres (2,230 ft) above sea level, Damascus experiences a semi-arid climate because of the rain shadow effect. The Barada River flows through Damascus. First settled in the second millennium BC, it was chosen as the capital of the Umayyad Caliphate from 661 to 750. After the victory of the Abbasid dynasty, the seat of Islamic power was moved to Baghdad. Damascus saw a political decline throughout the Abbasid era, only to regain significant importance in the Ayyubid and Mamluk periods. Today, it is the seat of the central government and all of the government ministries. As of 2018, Damascus has witnessed repeated conflicts and has been considered by Mercer as one of the most unfavorable places to live.

Bosnia and Herzegovina ( () or ; Serbo-Croatian: Bosna i Hercegovina [BiH] / Боснa и Херцеговина [БиХ]), sometimes called Bosnia–Herzegovina, and often known informally as Bosnia, is a country in Southeastern Europe, located within the Balkan Peninsula. Sarajevo is the capital and largest city.

Spain (Spanish: España [esˈpaɲa] ()), officially the Kingdom of Spain (Spanish: Reino de España), is a country mostly located in Europe. Its continental European territory is situated on the Iberian Peninsula. Its territory also includes two archipelagoes: the Canary Islands off the coast of Africa, and the Balearic Islands in the Mediterranean Sea. The African enclaves of Ceuta, Melilla, and Peñón de Vélez de la Gomera make Spain the only European country to have a physical border with an African country (Morocco). Several small islands in the Alboran Sea are also part of Spanish territory. The country's mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar; to the north and northeast by France, Andorra, and the Bay of Biscay;

Computational complexity theory focuses on classifying computational problems according to their inherent difficulty, and relating these classes to each other. A computational problem is a task solved by a computer. A computation problem is solvable by mechanical application of mathematical steps, such as an algorithm.

Italian cuisine is food typical of Italy. It has developed through centuries of social and economic changes, with roots stretching to antiquity. Significant changes occurred with the discovery of the New World and the introduction of potatoes, tomatoes, bell peppers, maize and sugar beet, this last introduced in quantity in the 18th century. Italian cuisine is known for its regional diversity, especially between the north and the south of the Italian peninsula. It offers an abundance of taste, and is one of the most popular and copied in the world. It influenced several cuisines around the world, chiefly that of the United States. Italian cuisine is generally characterized by its simplicity, with many dishes having only two to four main ingredients. Italian cooks rely chiefly on the quality of the ingredients rather than on elaborate preparation. Ingredients and dishes vary by region. Many dishes that were once regional have proliferated with variations throughout the country.

The cerebellum (Latin for "little brain") is a major feature of the hindbrain of all vertebrates. Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as or even larger. In humans, the cerebellum plays an important role in motor control. It may also be involved in some cognitive functions such as attention and language as well as in regulating fear and pleasure responses, but its movement-related functions are the most solidly established. The human cerebellum does not initiate movement, but contributes to coordination, precision, and accurate timing: it receives input from sensory systems of the spinal cord and from other parts of the brain, and integrates these inputs to fine-tune motor activity. Cerebellar damage produces disorders in fine movement, equilibrium, posture, and motor learning in humans. Anatomically, the human cerebellum has the appearance of a separate structure attached to the bottom of the brain, tucked underneath the cerebral hemispheres. Its cortical surface is covered with finely spaced parallel grooves, in striking contrast to the broad irregular convolutions of the cerebral cortex. These parallel grooves conceal the fact that the cerebellar cortex is actually a continuous thin layer of tissue tightly folded in the style of an accordion. Within this thin layer are several types of neurons with a highly regular arrangement, the most important being Purkinje cells and granule cells. This complex neural organization gives rise to a massive signal-processing capability, but almost all of the output from the cerebellar cortex passes through a set of small deep nuclei lying in the white matter interior of the cerebellum. In addition to its direct role in motor control, the cerebellum is necessary for several types of motor learning, most notably learning to adjust to changes in sensorimotor relationships. Several theoretical models have been developed to explain sensorimotor calibration in terms of synaptic plasticity within the cerebellum. These models derive from those formulated by David Marr and James Albus, based on the observation that each cerebellar Purkinje cell receives two dramatically different types of input: one comprises thousands of weak inputs from the parallel fibers of the granule cells; the other is an extremely strong input from a single climbing fiber. The basic concept of the Marr–Albus theory is that the climbing fiber serves as a "teaching signal", which induces a long-lasting change in the strength of parallel fiber inputs. Observations of long-term depression in parallel fiber inputs have provided support for theories of this type, but their validity remains controversial.

The East Germanic languages, also called the Oder–Vistula Germanic languages, are a group of extinct Germanic languages family spoken by East Germanic peoples. The only East Germanic languages of which texts are known are Gothic and its descendant, Crimean Gothic. Other languages that are assumed to be East Germanic include Vandalic and Burgundian, though very few texts in these languages are known. Crimean Gothic, the last remaining East Germanic language, is believed to have survived until the 18th century in isolated areas of Crimea.

Finance is a field that is concerned with the allocation (investment) of assets and liabilities over space and time, often under conditions of risk or uncertainty. Finance can also be defined as the art of money management. Participants in the market aim to price assets based on their risk level, fundamental value, and their expected rate of return. Finance can be split into three sub-categories: public finance, corporate finance and personal finance.

The University of Oxford has 38 Colleges and six Permanent Private Halls (PPHs) of religious foundation. Colleges and PPHs are autonomous self-governing corporations within the university, and all teaching staff and students studying for a degree at the university must belong to one of the colleges or PPHs. These colleges are not only houses of residence, but have substantial responsibility for teaching undergraduate students. Generally tutorials (one of the main methods of teaching in Oxford) and classes are the responsibility of colleges, while lectures, examinations, laboratories, and the central library are run by the university. Most colleges take both graduates and undergraduates, but several are for graduates only. Undergraduate and graduate students may name preferred colleges in their applications. For undergraduate students, an increasing number of departments practise reallocation to ensure that the ratios between potential students and subject places available at each college are as uniform as possible. For the Department of Physics, reallocation is done on a random basis after a shortlist of candidates is drawn upon and before candidates are invited for interviews at the university. For graduate students, many colleges express a preference for candidates who plan to undertake research in an area of interest of one of its fellows. St Hugh's College, for example, states that it accepts graduate students in most subjects, principally those in the fields of interest of the Fellows of the college. A typical college consists of a hall for dining, a chapel, a library, a college bar, senior, middle (postgraduate), and junior common rooms, rooms for 200–400 undergraduates as well as lodgings for the head of the college and other dons. College buildings range from medieval to modern, but most are made up of interlinked quadrangles (courtyards), with a porter's lodge controlling entry from the outside. 2008 saw the first modern merger of colleges, with Green College and Templeton College merging to form Green Templeton College. This reduced the number of Colleges of the University from 39 to 38. The number of PPHs also reduced in 2008, when Greyfriars closed down.

The vestibular system, in most mammals, is the sensory system that provides the leading contribution to the sense of balance and spatial orientation for the purpose of coordinating movement with balance. Together with the cochlea, a part of the auditory system, it constitutes the labyrinth of the inner ear in most mammals. As movements consist of rotations and translations, the vestibular system comprises two components: the semicircular canals which indicate rotational movements; and the otoliths which indicate linear accelerations. The vestibular system sends signals primarily to the neural structures that control eye movements, and to the muscles that keep an animal upright and in general control posture. The projections to the former provide the anatomical basis of the vestibulo-ocular reflex, which is required for clear vision; while the projections to the latter provide the anatomical means required to enable an animal to maintain its desired position in space. The brain uses information from the vestibular system in the head and from proprioception throughout the body to enable the animal to understand its body's dynamics and kinematics (including its position and acceleration) from moment to moment. How these two perceptive sources are integrated to provide the underlying structure of the sensorium is unknown.

St. Charles Parish (French: Paroisse de Saint-Charles) is a parish located in the U.S. state of Louisiana. As of the 2010 census, the population was 52,780. The parish seat is Hahnville. The parish was formed in 1807, following the Louisiana Purchase by the United States in 1803. It was originally part of the German Coast, an area along the east bank of the Mississippi River that was settled by numerous German pioneers in the 1720s. This was historically an area of sugarcane plantations. The parish includes territory on both sides of the river.

In political and social sciences, communism (from Latin communis, "common, universal") is the philosophical, social, political, and economic ideology and movement whose ultimate goal is the establishment of the communist society, which is a socioeconomic order structured upon the common ownership of the means of production and the absence of social classes, money, and the state. Communism includes a variety of schools of thought, which broadly include Marxism and anarchism (anarcho-communism), as well as the political ideologies grouped around both. All of these share the analysis that the current order of society stems from its economic system, capitalism; that in this system there are two major social classes; that conflict between these two classes is the root of all problems in society; and that this situation will ultimately be resolved through a social revolution.The two classes are the working class—who must work to survive and who make up the majority within society—and the capitalist class—a minority who derives profit from employing the working class through private ownership of the means of production.The revolution will put the working class in power and in turn establish social ownership of the means of production, which according to this analysis is the primary element in the transformation of society towards communism.Critics of communism can be roughly divided into those concerning themselves with the practical aspects of 20th century communist states and those concerning themselves with communist principles and theory. Marxism-Leninism and social democracy were the two dominant forms of socialism in the 20th century; social democracy advocates economic reform through gradual democratic legislative action rather than through revolution.

Eritrea (; ()), officially the State of Eritrea is a country in the Horn of Africa, with its capital at Asmara. It is bordered by Sudan in the west, Ethiopia in the south, and Djibouti in the southeast. The northeastern and eastern parts of Eritrea have an extensive coastline along the Red Sea. The nation has a total area of approximately 117,600 km2 (45,406 sq mi), and includes the Dahlak Archipelago and several of the Hanish Islands. Its toponym Eritrea is based on the Greek name for the Red Sea (Ἐρυθρὰ Θάλασσα Erythra Thalassa), which was first adopted for Italian Eritrea in 1890.

The Banu Umayya (Arabic: بَنُو أُمَيَّة‎, translit. Banū Umayya, lit. 'Sons of Umayya') or Umayyads (الأمويون), were the ruling family of the caliphate between 661 and 750 and later of Islamic Spain between 750 and 1031. In the pre-Islamic period, they were a prominent clan of the Quraysh tribe descended from Umayya ibn Abd Shams. Despite staunch opposition to the Islamic prophet Muhammad, the Umayyads embraced Islam before the latter's death in 632. A member of the clan, Uthman, went on to become the third Rashidun caliph in 644–656, while other members held various governorships. One of these governors, Mu'awiya I, won the First Muslim Civil War in 661 and established the Umayyad Caliphate with its capital in Damascus, Syria. This marked the beginning of the Umayyad dynasty, the first hereditary dynasty in the history of Islam, and the only one to rule over the entire Islamic world of its time. The Sufyanid line founded by Mu'awiya failed in 683 and Umayyad authority was challenged in the Second Muslim Civil War, but the dynasty ultimately prevailed under Marwan I, who founded the Marwanid line of Umayyad caliphs. The Umayyads drove on the early Muslim conquests, including North Africa, Spain, Central Asia, and Sindh, but the constant warfare exhausted the state's military resources, while Alid revolts and tribal rivalries weakened the regime from within. Finally, in 750 the Abbasid Revolution overthrew Caliph Marwan II and massacred most of the family. One of the survivors, Abd al-Rahman, a grandson of Caliph Hisham ibn Abd al-Malik, escaped to Muslim Spain (al-Andalus), where he founded the Umayyad Emirate of Córdoba, which Abd al-Rahman III elevated to the status of a caliphate in 929. After a brief golden era, the Caliphate of Córdoba disintegrated into several independent taifa kingdoms in 1031, thus marking a definitive end to the Umayyad dynasty.

Asia-Pacific Economic Cooperation (APEC) is an inter-governmental forum for 21 Pacific Rim member economies that promotes free trade throughout the Asia-Pacific region. Inspired from the success of Association of Southeast Asian Nations (ASEAN)’s series of post-ministerial conferences launched in the mid-1980s, the APEC was established in 1989 in response to the growing interdependence of Asia-Pacific economies and the advent of regional trade blocs in other parts of the world; and to establish new markets for agricultural products and raw materials beyond Europe. Headquartered in Singapore, the APEC is recognised as one of the oldest forums and highest-level multilateral blocs in the Asia-Pacific region, and exerts a significant global influence. An annual APEC Economic Leaders' Meeting is attended by the heads of government of all APEC members except Republic of China (which is represented by a ministerial-level official under the name Chinese Taipei as economic leader). The location of the meeting rotates annually among the member economies, and a famous tradition, followed for most (but not all) summits, involves the attending leaders dressing in a national costume of the host country. APEC has three official observers: the Association of Southeast Asian Nations Secretariat, the Pacific Economic Cooperation Council and the Pacific Islands Forum Secretariat. APEC's Host Economy of the Year is considered to be invited in the first place for geographical representation to attend G20 meetings following G20 guidelines.

The Heptarchy is a collective name applied to the seven kingdoms of Anglo-Saxon England (sometimes referred to as petty kingdoms) from the Anglo-Saxon settlement of Britain in the 5th century until their unification into the Kingdom of England in the early 10th century. The term "Heptarchy" (from the Greek ἑπταρχία heptarchia, from ἑπτά hepta "seven", ἀρχή arche "reign, rule" and the suffix -ία -ia)alludes to the tradition that there were seven Anglo-Saxon kingdoms, usually enumerated as:East Anglia, Essex, Kent, Mercia, Northumbria, Sussex, and Wessex. The historiographical tradition of the "seven kingdoms" is medieval, first recorded by Henry of Huntingdon in his Historia Anglorum (12th century);the term Heptarchy dates to the 16th century.

Spain (Spanish: España [esˈpaɲa] ()), officially the Kingdom of Spain (Spanish: Reino de España), is a country mostly located in Europe. Its continental European territory is situated on the Iberian Peninsula. Its territory also includes two archipelagoes: the Canary Islands off the coast of Africa, and the Balearic Islands in the Mediterranean Sea. The African enclaves of Ceuta, Melilla, and Peñón de Vélez de la Gomera make Spain the only European country to have a physical border with an African country (Morocco). Several small islands in the Alboran Sea are also part of Spanish territory. The country's mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar; to the north and northeast by France, Andorra, and the Bay of Biscay; and to the west and northwest by Portugal and the Atlantic Ocean. With an area of 505,990 km2 (195,360 sq mi), Spain is the largest country in Southern Europe, the second largest country in Western Europe and the European Union, and the fourth largest country in the European continent. By population, Spain is the sixth largest in Europe and the fifth in the European Union. Spain's capital and largest city is Madrid; other major urban areas include Barcelona, Valencia, Seville, Málaga and Bilbao. Modern humans first arrived in the Iberian Peninsula around 35,000 years ago. Iberian cultures along with ancient Phoenician, Greek, Celtic and Carthaginian settlements developed on the peninsula until it came under Roman rule around 200 BCE, after which the region was named Hispania, based on the earlier Phoenician name Sp(a)n or Spania. At the end of the Western Roman Empire the Germanic tribal confederations migrated from Central Europe, invaded the Iberian peninsula and established relatively independent realms in its western provinces, including the Suebi, Alans and Vandals. Eventually, the Visigoths would forcibly integrate all remaining independent territories in the peninsula, including Byzantine provinces, into the Kingdom of Toledo, which more or less unified politically, ecclesiastically and legally all the former Roman provinces or successor kingdoms of what was then documented as Hispania. In the early eighth century the Visigothic Kingdom fell to the Moors of the Umayyad Islamic Caliphate, who arrived to rule most of the peninsula in the year 726, leaving only a handful of small Christian realms in the north and lasting up to seven centuries in the Kingdom of Granada. This led to many wars during a long reconquering period across the Iberian Peninsula, which led to the creation of Kingdom of Leon, Kingdom of Castille, Kingdom of Aragon and Kingdom of Navarre as the main Christian kingdoms to face the invasion. Following the Moorish conquest, Europeans began a gradual process of retaking the region known as the Reconquista, which by the late 15th century culminated in the emergence of Spain as a unified country under the Catholic Monarchs. In the early modern period, Spain became the world's first global empire and the most powerful country in the world, leaving a large cultural and linguistic legacy that includes +570 million Hispanophones, making Spanish the world's second-most spoken native language, after Mandarin Chinese. During the Golden Age there were also many advancements in the arts, with world-famous painters such as Diego Velázquez.The most famous Spanish literary work, Don Quixote, was also published during the Golden Age. Spain hosts the world's third-largest number of UNESCO World Heritage Sites. Spain is a secular parliamentary democracy and a parliamentary monarchy, with King Felipe VI as head of state. It is a major developed country and a high income country, with the world's fourteenth largest economy by nominal GDP and sixteenth largest by purchasing power parity. It is a member of the United Nations (UN), the European Union (EU), the Eurozone, the Council of Europe (CoE), the Organization of Ibero-American States (OEI), the Union for the Mediterranean, the North Atlantic Treaty Organization (NATO), the Organisation for Economic Co-operation and Development (OECD), Organization for Security and Co-operation in Europe (OSCE), the Schengen Area, the World Trade Organization (WTO) and many other international organisations. While not an official member, Spain has a "Permanent Invitation" to the G20 summits, participating in every summit, which makes Spain a de facto member of the group.

Computational complexity theory focuses on classifying computational problems according to their inherent difficulty, and relating these classes to each other. A computational problem is a task solved by a computer. A computation problem is solvable by mechanical application of mathematical steps, such as an algorithm. A problem is regarded as inherently difficult if its solution requires significant resources, whatever the algorithm used. The theory formalizes this intuition, by introducing mathematical models of computation to study these problems and quantifying their computational complexity, i.e., the amount of resources needed to solve them, such as time and storage. Other measures of complexity are also used, such as the amount of communication (used in communication complexity), the number of gates in a circuit (used in circuit complexity) and the number of processors (used in parallel computing). One of the roles of computational complexity theory is to determine the practical limits on what computers can and cannot do. The P versus NP problem, one of the seven Millennium Prize Problems, is dedicated to the field of computational complexity. Closely related fields in theoretical computer science are analysis of algorithms and computability theory. A key distinction between analysis of algorithms and computational complexity theory is that the former is devoted to analyzing the amount of resources needed by a particular algorithm to solve a problem, whereas the latter asks a more general question about all possible algorithms that could be used to solve the same problem. More precisely, computational complexity theory tries to classify problems that can or cannot be solved with appropriately restricted resources. In turn, imposing restrictions on the available resources is what distinguishes computational complexity from computability theory: the latter theory asks what kind of problems can, in principle, be solved algorithmically.

Carrier-based aircraft, sometimes known as carrier-capable aircraft or carrier-borne aircraft, are naval aircraft designed for operations from aircraft carriers. They must be able to launch in a short distance and be sturdy enough to withstand the abrupt forces of launching from and recovering on a pitching deck. In addition, their wings are generally able to fold up, easing operations in tight quarters. The term is generally applied only to fixed-wing aircraft, as naval helicopters are able to operate from a wider variety of ships, including helicopter carriers and container ships.

mv (short for move) is a Unix command that moves one or more files or directories from one place to another. If both filenames are on the same filesystem, this results in a simple file rename; otherwise the file content is copied to the new location and the old file is removed. Using mv requires the user to have write permission for the directories the file will move between. This is because mv changes the content of both directories (i.e., the source and the target) involved in the move. When using the mv command on files located on the same filesystem, the file's timestamp is not updated.

When using the mv command on files located on the same filesystem, the file's timestamp is not updated. On UNIX implementations derived from AT&T UNIX, cp, ln and mv are implemented as a single program with hard-linked binaries. The behavior is selected from the last path component name in argv[0]. This is a common technique by which closely related commands that have been packaged as a unit allow the user to specify the particular course of intended action.

Bosnia and Herzegovina ( () or ; Serbo-Croatian: Bosna i Hercegovina [BiH] / Боснa и Херцеговина [БиХ]), sometimes called Bosnia–Herzegovina, and often known informally as Bosnia, is a country in Southeastern Europe, located within the Balkan Peninsula. Sarajevo is the capital and largest city. Bosnia and Herzegovina is an almost landlocked country – it has a narrow coast at the Adriatic Sea, about 20 kilometres (12 miles) long surrounding the town of Neum. It is bordered by Croatia to the north, west and south; Serbia to the east; and Montenegro to the southeast. In the central and eastern interior of the country the geography is mountainous, in the northwest it is moderately hilly, and the northeast is predominantly flatland. The inland, Bosnia, is a geographically larger region and has a moderate continental climate, with hot summers and cold and snowy winters. The southern tip, Herzegovina, has a Mediterranean climate and plain topography. Bosnia and Herzegovina traces permanent human settlement back to the Neolithic age, during and after which it was populated by several Illyrian and Celtic civilizations. Culturally, politically, and socially, the country has a rich history, having been first settled by the Slavic peoples that populate the area today from the 6th through to the 9th centuries. In the 12th century the Banate of Bosnia was established, which evolved into the Kingdom of Bosnia in the 14th century, after which it was annexed into the Ottoman Empire, under whose rule it remained from the mid-15th to the late 19th centuries. The Ottomans brought Islam to the region, and altered much of the cultural and social outlook of the country. This was followed by annexation into the Austro-Hungarian Monarchy, which lasted up until World War I. In the interwar period, Bosnia and Herzegovina was part of the Kingdom of Yugoslavia and after World War II, it was granted full republic status in the newly formed Socialist Federal Republic of Yugoslavia. Following the dissolution of Yugoslavia, the republic proclaimed independence in 1992, which was followed by the Bosnian War, lasting until late 1995. Tourism in Bosnia and Herzegovina has grown at double digit rates in recent years. Bosnia and Herzegovina is regionally and internationally renowned for its natural environment and cultural heritage inherited from six historical civilizations, its cuisine, winter sports, its eclectic and unique music, architecture, and its festivals, some of which are the largest and most prominent of their kind in Southeastern Europe. The country is home to three main ethnic groups or, officially, constituent peoples, as specified in the constitution. Bosniaks are the largest group of the three, with Serbs second, and Croats third. A native of Bosnia and Herzegovina, regardless of ethnicity, is usually identified in English as a Bosnian. Minorities, defined under the constitutional nomenclature "Others", include Jews, Roma, Poles, Ukrainians, and Turks. Bosnia and Herzegovina has a bicameral legislature and a three-member Presidency composed of a member of each major ethnic group. However, the central government's power is highly limited, as the country is largely decentralized and comprises two autonomous entities: the Federation of Bosnia and Herzegovina and Republika Srpska, with a third unit, the Brčko District, governed under local government. The Federation of Bosnia and Herzegovina consists of 10 cantons. Bosnia and Herzegovina ranks highly in terms of human development, and has an economy dominated by the industry and agriculture sectors, followed by the tourism and service sectors. The country has a social security and universal healthcare system, and primary- and secondary-level education is tuition-free. It is a member of the UN, OSCE, Council of Europe, PfP, CEFTA, and a founding member of the Union for the Mediterranean upon its establishment in July 2008. The country is a potential candidate for membership to the European Union and has been a candidate for NATO membership since April 2010, when it received a Membership Action Plan.

A wide variety of characters have appeared on the American children's television series Sesame Street. A large number of the characters are Muppets, which are puppets made in Jim Henson's distinctive puppet-creation style. Most of the non-Muppet characters are human characters, but there are many characters that are animated.

The Heptarchy is a collective name applied to the seven kingdoms of Anglo-Saxon England (sometimes referred to as petty kingdoms) from the Anglo-Saxon settlement of Britain in the 5th century until their unification into the Kingdom of England in the early 10th century. The term "Heptarchy" (from the Greek ἑπταρχία heptarchia, from ἑπτά hepta "seven", ἀρχή arche "reign, rule" and the suffix -ία -ia)alludes to the tradition that there were seven Anglo-Saxon kingdoms, usually enumerated as:East Anglia, Essex, Kent, Mercia, Northumbria, Sussex, and Wessex.

PepsiCo has interests in the manufacturing, marketing, and distribution of grain-based snack foods, beverages, and other products. PepsiCo was formed in 1965 with the merger of the Pepsi-Cola Company and Frito-Lay, Inc. PepsiCo has since expanded from its namesake product Pepsi to a broader range of food and beverage brands, the largest of which included an acquisition of Tropicana Products in 1998 and the Quaker Oats Company in 2001, which added the Gatorade brand to its portfolio.

Carrier-based aircraft, sometimes known as carrier-capable aircraft or carrier-borne aircraft, are naval aircraft designed for operations from aircraft carriers. They must be able to launch in a short distance and be sturdy enough to withstand the abrupt forces of launching from and recovering on a pitching deck. In addition, their wings are generally able to fold up, easing operations in tight quarters. Such aircraft are designed for many purposes including air-to-air combat, surface attack, anti-submarine warfare (ASW), search and rescue (SAR), transport (COD), weather observation, reconnaissance and airborne early warning and control (AEW&C) duties. The term is generally applied only to fixed-wing aircraft, as naval helicopters are able to operate from a wider variety of ships, including helicopter carriers and container ships.

The University of Oxford has 38 Colleges and six Permanent Private Halls (PPHs) of religious foundation. Colleges and PPHs are autonomous self-governing corporations within the university, and all teaching staff and students studying for a degree at the university must belong to one of the colleges or PPHs. These colleges are not only houses of residence, but have substantial responsibility for teaching undergraduate students. Generally tutorials (one of the main methods of teaching in Oxford) and classes are the responsibility of colleges, while lectures, examinations, laboratories, and the central library are run by the university. Most colleges take both graduates and undergraduates, but several are for graduates only.

The cerebellum (Latin for "little brain") is a major feature of the hindbrain of all vertebrates. Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as or even larger. In humans, the cerebellum plays an important role in motor control. It may also be involved in some cognitive functions such as attention and language as well as in regulating fear and pleasure responses, but its movement-related functions are the most solidly established. The human cerebellum does not initiate movement, but contributes to coordination, precision, and accurate timing: it receives input from sensory systems of the spinal cord and from other parts of the brain, and integrates these inputs to fine-tune motor activity. Cerebellar damage produces disorders i

The vestibular system, in most mammals, is the sensory system that provides the leading contribution to the sense of balance and spatial orientation for the purpose of coordinating movement with balance. Together with the cochlea, a part of the auditory system, it constitutes the labyrinth of the inner ear in most mammals. As movements consist of rotations and translations, the vestibular system comprises two components: the semicircular canals which indicate rotational movements; and the otoliths which indicate linear accelerations. The vestibular system sends signals primarily to the neural structures that control eye movements, and to the muscles that keep an animal upright and in general control posture. The projections to the former provide the anatomical basis of the vestibulo-ocular

Lepidoptera ( LEP-i-DOP-tər-ə) is an order of insects that includes butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 families and 46 superfamilies, 10 per cent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most speciose orders, along with the Hymenoptera, Diptera, and Coleoptera.

Kuwait ( (); Arabic: الكويت‎ al-Kuwait, Gulf Arabic pronunciation: [ɪl‿ɪkweːt] or [lɪkweːt]), officially the State of Kuwait (Arabic: دولة الكويت‎ ), is a country in Western Asia. Situated in the northern edge of Eastern Arabia at the tip of the Persian Gulf, it shares borders with Iraq and Saudi Arabia. As of 2016, Kuwait has a population of 4.5 million people: 1.3 million are Kuwaitis and 3.2 million are expatriates. Expatriates account for 70% of the population.

The counties of Ireland (Irish: contaetha na hÉireann; Ulster-Scots: coonties o Airlann) are sub-national divisions that have been, and in some cases continue to be, used to geographically demarcate areas of local government. These land divisions were formed following the Norman invasion of Ireland in imitation of the counties then in use as units of local government in the Kingdom of England. The older term "shire" was historically equivalent to "county". The principal function of the county was to impose royal control in the areas of taxation, security and the administration of justice at the local level. Cambro-Norman control was initially limited to the southeastern parts of Ireland; a further four centuries elapsed before the entire island was shired. At the same time, the now obsolete concept of county corporate elevated a small number of towns and cities to a status which was deemed to be no less important than the existing counties in which they lay. This double control mechanism of 32 counties plus 10 counties corporate remained unchanged for a little over two centuries until the early 19th century. Since then, counties have been adapted and in some cases divided by legislation to meet new administrative and political requirements. The powers exercised by the Cambro-Norman barons and the Old English nobility waned over time. New offices of political control came to be established at a county level. In the Republic of Ireland, some counties have been split resulting in the creation of new counties. Along with certain defined cities, counties still form the basis for the demarcation of areas of local government in the Republic of Ireland. Currently, there are 26 county level, 3 city level and 2 city and county entities – the modern equivalent of counties corporate – that are used to demarcate areas of local government in the Republic. In Northern Ireland, counties are no longer used for local government; districts are instead used. Upon the partition of Ireland in 1921, the county became one of the basic land divisions employed, along with county boroughs.

Kuwait ( (); Arabic: الكويت‎ al-Kuwait, Gulf Arabic pronunciation: [ɪl‿ɪkweːt] or [lɪkweːt]), officially the State of Kuwait (Arabic: دولة الكويت‎ ), is a country in Western Asia.

As of 2016, Kuwait has a population of 4.5 million people: 1.3 million are Kuwaitis and 3.2 million are expatriates. Expatriates account for 70% of the population. Oil reserves were discovered in commercial quantities in 1938. From 1946 to 1982, the country underwent large-scale modernization. In the 1980s, Kuwait experienced a period of geopolitical instability and an economic crisis following the stock market crash. In 1990, Kuwait was invaded, and later annexed, by Saddam's Iraq. The Iraqi occupation of Kuwait came to an end in 1991 after military intervention by a military coalition led by the United States. Kuwait is a major non-NATO ally of the United States. It is also a major ally of ASEAN, while maintaining a strong relationship with China. Kuwait is a constitutional sovereign state with a semi-democratic political system. Kuwait has a high-income economy backed by the world's sixth largest oil reserves. The Kuwaiti dinar is the highest valued currency in the world. According to the World Bank, the country has the fourth highest per capita income. The Constitution was promulgated in 1962. Kuwait is home to the largest opera house in the Middle East. The Kuwait National Cultural District is a member of the Global Cultural Districts Network.

Asia-Pacific Economic Cooperation (APEC) is an inter-governmental forum for 21 Pacific Rim member economies that promotes free trade throughout the Asia-Pacific region. Inspired from the success of Association of Southeast Asian Nations (ASEAN)’s series of post-ministerial conferences launched in the mid-1980s, the APEC was established in 1989 in response to the growing interdependence of Asia-Pacific economies and the advent of regional trade blocs in other parts of the world; and to establish new markets for agricultural products and raw materials beyond Europe. Headquartered in Singapore, the APEC is recognised as one of the oldest forums and highest-level multilateral blocs in the Asia-Pacific region, and exerts a significant global influence.

Eritrea (; ()), officially the State of Eritrea is a country in the Horn of Africa, with its capital at Asmara. It is bordered by Sudan in the west, Ethiopia in the south, and Djibouti in the southeast. The northeastern and eastern parts of Eritrea have an extensive coastline along the Red Sea. The nation has a total area of approximately 117,600 km2 (45,406 sq mi), and includes the Dahlak Archipelago and several of the Hanish Islands. Its toponym Eritrea is based on the Greek name for the Red Sea (Ἐρυθρὰ Θάλασσα Erythra Thalassa), which was first adopted for Italian Eritrea in 1890. Eritrea is a multi-ethnic country, with nine recognized ethnic groups in its population of around 5 million. Most residents speak languages from the Afroasiatic family, either of the Ethiopian Semitic languages or Cushitic branches. Among these communities, the Tigrinyas make up about 55% of the population, with the Tigre people constituting around 30% of inhabitants. In addition, there are a number of Nilo-Saharan-speaking Nilotic ethnic minorities. Most people in the territory adhere to Christianity or Islam. The Kingdom of Aksum, covering much of modern-day Eritrea and northern Ethiopia, was established during the first or second centuries AD. It adopted Christianity around the middle of the fourth century. In medieval times much of Eritrea fell under the Medri Bahri kingdom, with a smaller region being part of Hamasien. The creation of modern-day Eritrea is a result of the incorporation of independent, distinct kingdoms and sultanates (for example, Medri Bahri and the Sultanate of Aussa) eventually resulting in the formation of Italian Eritrea. After the defeat of the Italian colonial army in 1942, Eritrea was administered by the British Military Administration until 1952. Following the UN General Assembly decision, in 1952, Eritrea would govern itself with a local Eritrean parliament but for foreign affairs and defense it would enter into a federal status with Ethiopia for a period of 10 years. However, in 1962 the government of Ethiopia annulled the Eritrean parliament and formally annexed Eritrea. But the Eritreans that argued for complete Eritrean independence since the ouster of the Italians in 1941, anticipated what was coming and in 1960 organized the Eritrean Liberation Front in opposition. In 1991, after 30 years of continuous armed struggle for independence, the Eritrean liberation fighters entered the capital city, Asmara, in victory. Eritrea is a one-party state in which national legislative elections have never been held since independence. According to Human Rights Watch, the Eritrean government's human rights record is among the worst in the world. The Eritrean government has dismissed these allegations as politically motivated. The compulsory military service requires long, indefinite conscription periods, which some Eritreans leave the country to avoid. Because all local media is state-owned, Eritrea was also ranked as having the second-least press freedom in the global Press Freedom Index, behind only North Korea. The sovereign state of Eritrea is a member of the African Union, the United Nations, and the Intergovernmental Authority on Development, and is an observer in the Arab League alongside Brazil, Venezuela, India and Turkey.

Microsoft Corporation (MS) is an American multinational technology company with headquarters in Redmond, Washington. It develops, manufactures, licenses, supports and sells computer software, consumer electronics, personal computers, and related services. Its best known software products are the Microsoft Windows line of operating systems, the Microsoft Office suite, and the Internet Explorer and Edge web browsers. Its flagship hardware products are the Xbox video game consoles and the Microsoft Surface lineup of touchscreen personal computers. As of 2016, it is the world's largest software maker by revenue, and one of the world's most valuable companies. The word "Microsoft" is a portmanteau of "microcomputer" and "software". Microsoft is ranked No. 30 in the 2018 Fortune 500 rankings of the largest United States corporations by total revenue. Microsoft was founded by Bill Gates and Paul Allen on April 4, 1975, to develop and sell BASIC interpreters for the Altair 8800. It rose to dominate the personal computer operating system market with MS-DOS in the mid-1980s, followed by Microsoft Windows. The company's 1986 initial public offering (IPO), and subsequent rise in its share price, created three billionaires and an estimated 12,000 millionaires among Microsoft employees. Since the 1990s, it has increasingly diversified from the operating system market and has made a number of corporate acquisitions, their largest being the acquisition of LinkedIn for $26.2 billion in December 2016, followed by their acquisition of Skype Technologies for $8.5 billion in May 2011. As of 2015, Microsoft is market-dominant in the IBM PC-compatible operating system market and the office software suite market, although it has lost the majority of the overall operating system market to Android. The company also produces a wide range of other consumer and enterprise software for desktops and servers, including Internet search (with Bing), the digital services market (through MSN), mixed reality (HoloLens), cloud computing (Azure) and software development (Visual Studio). Steve Ballmer replaced Gates as CEO in 2000, and later envisioned a "devices and services" strategy. This began with the acquisition of Danger Inc. in 2008, entering the personal computer production market for the first time in June 2012 with the launch of the Microsoft Surface line of tablet computers; and later forming Microsoft Mobile through the acquisition of Nokia's devices and services division. Since Satya Nadella took over as CEO in 2014, the company has scaled back on hardware and has instead focused on cloud computing, a move that helped the company's shares reach its highest value since December 1999. In 2018, Microsoft surpassed Apple as the most valuable publicly traded company in the world after being dethroned by the tech giant in 2010.

It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most speciose orders, along with the Hymenoptera, Diptera, and Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scales that cover the bodies, wings, and a proboscis. The scales are modified, flattened "hairs", and give butterflies and moths their wide variety of colors and patterns. Almost all species have some form of membranous wings, except for a few that have reduced wings or are wingless. Mating and the laying of eggs are carried out by adults, normally near or on host plants for the larvae. Like most other insects, butterflies and moths are holometabolous, meaning they undergo complete metamorphosis. The larvae are commonly called caterpillars, and are completely different from their adult moth or butterfly forms, having a cylindrical body with a well-developed head, mandible mouth parts, three pairs of thoracic legs and from none up to five pairs of prolegs. As they grow, these larvae change in appearance, going through a series of stages called instars. Once fully matured, the larva develops into a pupa. A few butterflies and many moth species spin a silk case or cocoon prior to pupating, while others do not, instead going underground. A butterfly pupa, called a chrysalis, has a hard skin, usually with no cocoon. Once the pupa has completed its metamorphosis, a sexually mature adult emerges. The Lepidoptera have, over millions of years, evolved a wide range of wing patterns and coloration ranging from drab moths akin to the related order Trichoptera, to the brightly colored and complex-patterned butterflies. Accordingly, this is the most recognized and popular of insect orders with many people involved in the observation, study, collection, rearing of, and commerce in these insects. A person who collects or studies this order is referred to as a lepidopterist. Butterflies and moths play an important role in the natural ecosystem as pollinators and as food in the food chain; conversely, their larvae are considered very problematic to vegetation in agriculture, as their main source of food is often live plant matter. In many species, the female may produce from 200 to 600 eggs, while in others, the number may approach 30,000 eggs in one day. The caterpillars hatching from these eggs can cause damage to large quantities of crops. Many moth and butterfly species are of economic interest by virtue of their role as pollinators, the silk they produce, or as pest species.
