Barracuda-class submarine (France)

The Barracuda class (or Suffren class) is a nuclear attack submarine, designed by the French shipbuilder Naval Group (formerly known as DCNS and DCN) for the French Navy. It is intended to replace the Rubis-class submarines. Construction began in 2007 and the first unit will be commissioned in 2020.

Cartwheel cell

Cartwheel cells are neurons of the dorsal cochlear nucleus (DCN) where they greatly outnumber the other inhibitory interneurons of the DCN. Their somas lie on the superficial side of the pyramidal layer of the DCN, and their dendrites receive input from the parallel fibres of the granule cell layer. Their axons do not extend beyond the dorsal cochlear nucleus but synapse with other cartwheel cells and pyramidal cells within the DCN releasing GABA and glycine onto their targets.

Cartwheel cells have similar spiking patterns to Purkinje cells, firing complex spike bursts as well as simple spikes. They are also seen to share other features common to the cerebellar Purkinje cells. Other data supports the structural and functional similarity found between the cartwheel and the Purkinje neuron. Cartwheel cells are shown to have a high density of spines on their dendrites, their axons are myelinated, they are of spherical cell shape and of medium size. The primary targets of the cartwheel cells are the large efferent pyramidal neurons of the DCN, found in layer two. Data retrieved has shown that this targeting of the pyramidal cells modulates their activity and therefore plays a key role in the shaping of the overall output of the superficial layers of the dorsal cochlear nucleus.

Cochlear nucleus

The cochlear nuclear (CN) complex comprises two cranial nerve nuclei in the human brainstem, the ventral cochlear nucleus (VCN) and the dorsal cochlear nucleus (DCN).

The ventral cochlear nucleus is unlayered whereas the dorsal cochlear nucleus is layered. Auditory nerve fibers, fibers that travel through the auditory nerve (also known as the cochlear nerve or eighth cranial nerve) carry information from the inner ear, the cochlea, on the same side of the head, to the nerve root in the ventral cochlear nucleus.

At the nerve root the fibers branch to innervate the ventral cochlear nucleus and the deep layer of the dorsal cochlear nucleus. All acoustic information thus enters the brain through the cochlear nuclei, where the processing of acoustic information begins. The outputs from the cochlear nuclei are received in higher regions of the auditory brainstem.

Daily Cargo News

Daily Cargo News (DCN) is a monthly Australian shipping, trade, transport and logistics focused magazine, published by Paragon Media. First published in 1891 as Daily Commercial News, Daily Cargo News is Australia's longest running national newspaper.

Data center network architectures

Data center is a pool of resources (computational, storage, network) interconnected using a communication network. Data Center Network (DCN) holds a pivotal role in a data center, as it interconnects all of the data center resources together. DCNs need to be scalable and efficient to connect tens or even hundreds of thousands of servers to handle the growing demands of Cloud computing. Today’s data centers are constrained by the interconnection network.


Decorin is a protein that in humans is encoded by the DCN gene.

Decorin is a proteoglycan that is on average 90 - 140 kilodaltons (kDa) in molecular weight. It belongs to the small leucine-rich proteoglycan (SLRP) family and consists of a protein core containing leucine repeats with a glycosaminoglycan (GAG) chain consisting of either chondroitin sulfate (CS) or dermatan sulfate (DS).

Decorin is a small cellular or pericellular matrix proteoglycan and is closely related in structure to biglycan protein. Decorin and biglycan are thought to be the result of a gene duplication. This protein is a component of connective tissue, binds to type I collagen fibrils, and plays a role in matrix assembly.

Deputy Chief of Navy (Australia)

The Deputy Chief of Navy (DCN) is the second most senior appointment in the Royal Australian Navy, responsible to the Chief of Navy (CN). The rank associated with the position is rear admiral (2-star).

Digital Content Next

It was known as the Online Publishers Association (OPA) until May 2014. The organization represents more than 75 media companies based in the United States and abroad, with activities focused mostly in the U.S.

Direction générale de l'armement

The Direction générale de l’armement (DGA; English: Directorate General of Armaments), is the French Government Defense procurement and technology agency responsible for the program management, development and purchase of weapon systems for the French military.

Dorsal cochlear nucleus

The dorsal cochlear nucleus (DCN, also known as the "tuberculum acusticum"), is a cortex-like structure on the dorso-lateral surface of the brainstem. Along with the ventral cochlear nucleus (VCN), it forms the cochlear nucleus (CN), where all auditory nerve fibers from the cochlea form their first synapses.

Drum Corps Europe

Drum Corps Europe (DCE) is a governing body for all-age drum and bugle corps based in Biddinghuizen, Netherlands. DCE coordinates the European Music Games, including the annual European Championships, in cooperation with strategic partners from the United Kingdom, Ireland, and Germany. DCE also hosts the Dutch Music Games which were previously hosted by the defunct Drum Corps Nederland (DCN).The DCE European Championships have been hosted at Parkstad Limburg Stadion in Kerkrade since 2008.

DCE was reorganized in 2018 following a brief closure in 2017. The European Music Games (EMG) Judging Guide, utilized by other governing bodies within Europe, is developed and published by DCE's adjudicators.

Dynamic circuit network

A dynamic circuit network (DCN) is an advanced computer networking technology that combines traditional packet-switched communication based on the Internet Protocol, as used in the Internet, with circuit-switched technologies that are characteristic of traditional telephone network systems. This combination allows user-initiated ad hoc dedicated allocation of network bandwidth for high-demand, real-time applications and network services, delivered over an optical fiber infrastructure.

French submarine Le Triomphant (S616)

Le Triomphant is a strategic nuclear submarine of the French Navy; the submarine is the lead boat of class commissioned on the 21st of March 1997 with the home port of Île Longue. During active service Le Triomphant had suffered a nuclear leak from one of her nuclear warheads by the end of 1997 and from her reactor in 2004, though the FOST downplayed the incidents and stated no radiation had been released since the reactor had been non-operational at the time. The vessel carries sixteen strategic missiles, which launching can only be authorized by the President of France.

In the night between 3–4 February 2009, Le Triomphant collided with the Royal Navy submarine HMS Vanguard. Le Triomphant was reported to have proceeded to Brest under the boat's own power, submerged, to assess damages around the sonar area. On both boats, no damage was incurred on the nuclear installations. The French Navy at first claimed that Le Triomphant had collided with a container. After Vanguard returned to harbour, it was confirmed that the light brief contact collision was in fact with the Vanguard.

La Fayette-class frigate

The La Fayette class (also known as FL-3000 for "Frégate Légère de 3,000 tonnes", or FLF for Frégate Légère Furtive) are general purpose frigates built by DCNS and operated by the French Navy. Derivatives of the type are in service in Saudi Arabia (Royal Saudi Navy), Singapore (Republic of Singapore Navy) and Taiwan (Republic of China Navy).

The ships were originally known as "stealth frigates" due to their unique stealth design at the time. Their reduced radar cross section is achieved by a clean superstructure compared to conventional designs, angled sides and radar absorbent material, a composite material of wood and glass fibre as hard as steel, light, and resistant to fire. Most modern combat ships built since the introduction of the La Fayette class have followed the same principles of stealth.

All information gathered by the onboard sensors is managed by the Information Processing System, the electronic brain of the operation centre of the ship. It is completed by an electronic command aid system.

The La Fayette class has space available for the future installation of the Aster 15 air-defence missile, however they will not be installed due to recent cost issues. The ships are designed to accommodate a 10-tonne helicopter in the Panther or NH90 range (though they are also capable of operating the Super Frelon and similar heavy helicopters). These helicopters can carry antiship missiles AM39 or AS15, and they can be launched during sea state five or six due to the Samahé helicopter handling system. France ordered five ships of the La Fayette class in 1988, the last of which entered service in 2002. They may be replaced in French service by five frégates de taille intermédiaire (FTI, "intermediate size frigates") starting in 2023.

Naval Group

Naval Group (formerly known as DCNS) is a French industrial group specialised in naval defence and marine renewable energy. The group employs next to 13,000 people in 18 countries. The company is owned in part by the Agence des participations de l'État, a private company through which the French state holds a 62.49% stake, Thales holds 35% and the personnel a 1.64% stake. The remaining 0.87% are owned by the heir to the French naval dockyards and the Direction des Constructions et Armes Navales (DCAN), which became the DCN (Direction des Constructions Navales) in 1991, DCNS in 2007 and Naval Group since 2017.

Other Backward Class

Other Backward Class (OBC) is a collective term used by the Government of India to classify castes which are educationally or socially disadvantaged. It is one of several official classifications of the population of India, along with Scheduled Castes and Scheduled Tribes (SCs and STs). The OBCs were found to comprise 52% of the country's population by the Mandal Commission report of 1980, a figure which had shrunk to 41% by 2006 when the National Sample Survey Organisation took place. There is substantial debate over the exact number of OBCs in India; it is generally estimated to be sizable, but many believe that it is higher than the figures quoted by either the Mandal Commission or the National Sample Survey.In the Indian Constitution, OBCs are described as "socially and educationally backward classes", and the Government of India is enjoined to ensure their social and educational development — for example, the OBCs are entitled to 27% reservations in public sector employment and higher education. The list of OBCs maintained by the Indian Ministry of Social Justice and Empowerment is dynamic, with castes and communities being added or removed depending on social, educational and economic factors. In spite of the 27% reservation, RTI data showed that in 2015 OBCs held less than 12% of those jobs (in some departments, OBCs held only 6.67% of the employment under the 27% reservations). Likewise, in 2015, at educational institutes, funds meant for OBC students under the reservation policy were not used properly or were underused in cases of upgrading infrastructure as well as in violation of faculty recruitment of OBCs according to the 27% reservation policy.Until 1985, the affairs of the Backward Classes were looked after by the Backward Classes Cell in the Ministry of Home Affairs. A separate Ministry of Welfare was established in 1985 (renamed in 1998 to the Ministry of Social Justice and Empowerment) to attend to matters relating to Scheduled Castes, Scheduled Tribes and OBCs. The Backward Classes Division of the Ministry looks after the policy, planning and implementation of programmes relating to social and economic empowerment of OBCs, and matters relating to two institutions set up for the welfare of OBCs, the National Backward Classes Finance and Development Corporation and the National Commission for Backward Classes.

RAAF Base Curtin

RAAF Base Curtin, also sometimes RAAF Curtin (IATA: DCN, ICAO: YCIN) is a joint use Royal Australian Air Force (RAAF) military air base and civil airport located 19 nautical miles (35 km; 22 mi) southeast of the town of Derby on the north coast of Western Australia in Australia. As it is one of the RAAF's three 'bare bases', no RAAF units are permanently based at Curtin and it is maintained by a small caretaker staff during peacetime.

The base is named in honour of former Prime Minister John Curtin.
