Inelastic Neutron Scattering
Inelastic neutron scattering (INS) is a spectroscopy based on the energy analysis of neutrons after they have been scattered by a sample. A detected energy transfer can be related to a physical interaction of the corresponding atoms with their environment. An energy transfer of several meVs typically arises from vibrations of atoms. Thus, INS provides an amplitude-of-motion and neutron incoherent cross section weighted phonon density of states.  Given the much higher incoherent scattering cross section of hydrogen relative to that of all other elements, INS is particular sensitive to hydrogen based vibrations. The method is widely used in condensed matter physics and solid state chemistry, because the vibrational properties of matter define various physical properties such as the heat capacity. If used as a fingerprint method, INS can be used to characterize chemical bonds both in the bulk as well as on the surface.

The Cat Mandible
The cat mandible is small and has some peculiarities relative to the dentition (only three incisors, a prominent canine, two premolars and one molar); a conical and horizontally oriented condyle, and a protudent angular process in its ventrocaudal part. Most of the body of the mandible is occupied by the mandibular dental roots and the mandibular canal that protects the neurovascular supply: the inferior alveolar artery and vein, and the inferior alveolar nerve that exits the mandible rostrally as the mental nerves. They irrigate and innervate all the teeth and associated structures such as the lips and gingiva. Tooth roots and the mandibular canal account for up to 70% of the volume of the mandibular body. Consequently, when fractured it is difficult to repair without invading the dental roots or vascular structures.

Properties of Phase Change Materials
The main drawback of phase change materials (PCMs) is their low thermal conductivity, which limits the possibilities of a wide range of implementations. Therefore, the researchers, as found in the literature, proposed several methods to improve the thermal conductivity of PCMs, including inserting high thermal conductivity materials in nano-, micro-, and macro-scales, as well as encapsulation of PCMs. However, these inserts impact the other properties of PCMs like latent heat, melting temperature, thermal stability, and cycling stability.

Maitreya
Template:Infobox Buddha Maitreya (Sanskrit), Metteyya (Pali), is regarded as a future Buddha of this world in Buddhist eschatology. In some Buddhist literature, such as the Amitabha Sutra and the Lotus Sutra, he is referred to as Ajita. According to Buddhist tradition, Maitreya is a bodhisattva who will appear on Earth in the future, achieve complete enlightenment, and teach the pure dharma. According to scriptures, Maitreya will be a successor to the present Buddha, Gautama Buddha (also known as Śākyamuni Buddha). The prophecy of the arrival of Maitreya refers to a time in the future when the dharma will have been forgotten by most on the terrestrial world. Maitreya has also been adopted for his millenarian role by many non-Buddhist religions in the past, such as the White Lotus, as well as by modern new religious movements, such as Yiguandao.

CNBC Ticker
The CNBC Ticker is a computer simulation of ticker tapes used by the United States business news-oriented television network CNBC (as well as its international sister channels), that is displayed as a crawl on the lower part of the television screen. The CNBC Ticker shows security and index symbols in the manner of the ticker tapes that received information by telegraph. The security identifiers used on the CNBC Ticker are taken from nomenclatures used by third-party companies like Reuters or from global stock exchanges. The ticker is composed of a faster-scrolling upper band with a white background and a slower-scrolling lower band with a dark blue background for all CNBC channels. In addition for some channels, such as CNBC Europe; CNBC-e; CNBC Arabiya and Class CNBC, a third business news band is displayed in gray with a black background. The ticker is shown throughout the duration of financial news programming on CNBC's domestic and international channels, including national commercial breaks. However, in the United States and Canada , advertisements that are locally inserted by cable television providers may be shown full-screen, omitting the ticker from being displayed during local breaks (as of 2013, all ad inserts by cable television providers, as well as satellite television providers DirecTV and Dish Network are now shown full-screen).

Decline of Christianity
The decline of Christianity is an ongoing trend in Europe. Developed countries with good educational facilities in the post-World War II era have shifted towards post-Christian, secular, globalized, multicultural and multifaith societies. Infant baptism has declined in many nations, with thousands of churches closing or merging due to lack of attendees. There is also evidence of decline in North America. Despite the decline, Christianity remains the dominant religion in the Western world, where 70% of the population is nominally Christian.

Big Data Mining
Big data mining (BDM) is an approach that uses the cumulative data mining or extraction techniques on large datasets / volumes of data. It is mainly focused on retrieving relevant and demanded information (or patterns) and thus extracting value hidden in data of an immense volume. BDM draws from the conventional data mining notation but also combines the aspects of big data, i.e. it enables to acquire useful information from databases or data streams that are huge in terms of “big data V’s”, like volume, velocity, and variety.

Rudra
Rudra (/ˈrʊdrə/; Sanskrit: रुद्र) is a Rigvedic deity, associated with wind or storm and the hunt. One translation of the name is "the roarer". In the Rigveda, Rudra has been praised as the "mightiest of the mighty". Rudra is the personification of 'terror'. Depending up on the periodic situation, Rudra can be meant as the most severe roarer/howler (could be a hurricane or tempest) or the most frightening one. The Shri Rudram hymn from the Yajurveda is dedicated to Rudra, and is important in the Saivism sect. The Hindu god Shiva shares several features with the Rudra: the theonym Shiva originated as an epithet of Rudra, the adjective shiva ("kind") being used euphemistically of Rudra, who also carries the epithet Aghora, Abhayankar ("extremely calm [sic] non terrifying"). Usage of the epithet came to exceed the original theonym by the post-Vedic period (in the Sanskrit Epics), and the name Rudra has been taken as a synonym for the god Shiva and the two names are used interchangeably.

Song of Ascents
Song of Ascents is a title given to fifteen of the Psalms, 120–134 (119–133 in the Septuagint and the Vulgate), each starting with the superscription Shir Hama'aloth (שיר המעלות šîr ha-ma‘ălōṯ, meaning "Song of the Ascents"), or, in the case of Psalm 121, Shir Lama'aloth (שיר למעלות šîr la-ma‘ălōṯ, "a song regarding ascents"). They are also variously called Gradual Psalms, Fifteen Psalms, Songs of Degrees, Songs of Steps, songs for going up to worship or Pilgrim Songs. Four of them (Psalms 122, 124, 131, and 133) are linked in their ascriptions to David, and one (127) to Solomon. Three of them (Psalms 131, 133, and 134) have only three verses. The longest is Psalm 132 (18 verses).

Irreligion in India
Atheism and agnosticism have a long history in India and flourished within the Śramaṇa movement. Indian religions like Jainism, Hinduism and Buddhism consider atheism to be acceptable. India has produced some notable atheist politicians and social reformers. According to the 2011 Census of India, 99.76% of Indians identified with a religion while 0.24% did not state their religious identity. According to the 2012 WIN-Gallup Global Index of Religion and Atheism report, 81% of Indians were religious, 13% were non-religious, 3% were convinced atheists, and 3% were unsure or did not respond.

North–South Divide
The North–South divide is a socio-economic and political division of Earth popularized in the late 20th century and early 21st century. Generally, definitions of the Global North include the United States , Canada , almost all the European countries, Israel, Cyprus, Japan , Singapore, South Korea , Australia , and New Zealand. The Global South is made up of Sub-Saharan Africa, Latin America and the Caribbean, Pacific Islands, and the developing countries in Asia, including the Middle East. It is home to the BRIC countries (excluding Russia ): Brazil , India and China , which, along with Indonesia and Mexico, are the largest Southern states in terms of land area and population. The North is mostly correlated with the Western world and the First World, plus much of the Second World, while the South largely corresponds with the Third World and Eastern world. The two groups are often defined in terms of their differing levels of wealth, economic development, income inequality, democracy, and political and economic freedom, as defined by freedom indices. Nations in the North tend to be wealthier, less unequal and considered more democratic and to be developed countries who export technologically advanced manufactured products; Southern states are generally poorer developing countries with younger, more fragile democracies heavily dependent on primary sector exports and frequently share a history of past colonialism by Northern states. Nevertheless, the divide between the North and the South is often challenged and said to be increasingly incompatible with reality. In economic terms, as of the early 21st century, the North—with one quarter of the world population—controls four-fifths of the income earned anywhere in the world. 90% of the manufacturing industries are owned by and located in the North. Inversely, the South—with three quarters of the world population—has access to one-fifth of the world income. As nations become economically developed, they may become part of definitions the "North", regardless of geographical location; similarly, any nations that do not qualify for "developed" status are in effect deemed to be part of the "South".

Rheinmetall 120 Mm Gun
The Rheinmetall 120 mm gun is a smoothbore tank gun designed and produced by the West German Rheinmetall-DeTec AG company, developed in response to Soviet advances in armor technology and development of new armored threats. Production began in 1974, with the first version of the gun, known as the L/44 as it was 44 calibers long, used on the German Leopard 2 tank and soon produced under license for the American M1A1 Abrams and other tanks. The American version, the M256, uses a coil spring recoil system instead of a hydraulic system. The 120-millimeter (4.7 in) gun has a length of 5.28 meters (17.3 ft), and the gun system weighs approximately 3,317 kilograms (7,313 lb). By 1990, the L/44 was not considered powerful enough to deal with future Soviet armour, which stimulated an effort by Rheinmetall to develop a better main armament. This first involved a 140-millimeter (5.5 in) tank gun named Neue Panzerkanone 140 ("new tank gun 140"), but later turned into a compromise which led to the development of an advanced 120 mm gun, the L/55, based on the same internal geometry as the L/44 and installed in the same breech and mount. The L/55 is 1.32 meters (4.3 ft) longer, giving increased muzzle velocity to ammunition fired through it. As the L/55 retains the same barrel geometry, it can fire the same ammunition as the L/44. This gun was retrofitted into German and Dutch Leopard 2s, and chosen as the main gun of the Spanish Leopard 2E and the Greek Leopard 2HEL. It was tested on the British Challenger 2 as a potential replacement for its current weapon, the rifled L30 120 mm cannon. A variety of ammunition has been developed for use by tanks with guns based on Rheinmetall's original L/44 design. This includes a series of kinetic energy penetrators, such as the American M829 series, and high explosive anti-tank warheads. Recent ammunition includes a range of anti-personnel rounds and demolition munitions. The LAHAT, developed in Israel, is a gun-launched missile which has received interest from Germany and other Leopard 2 users, and is designed to defeat both land armour and combat helicopters. The Israelis also introduced a new anti-personnel munition which limits collateral damage by controlling the fragmentation of the projectile.
