Clusters are not a syntactic language construct, but rather a standard organizational convention.

Clusters of galaxies are often dominated by a single giant elliptical galaxy, known as the brightest cluster galaxy, which, over time, tidally destroys its satellite galaxies and adds their mass to its own.

Clusters are then formed relatively recently between 10 billion years ago and now.

Clusters are larger than groups, although there is no sharp dividing line between the two.

Clusters are quite prominent in X-ray surveys and along with AGN are the brightest X-ray emitting extragalactic objects.

Clusters of galaxies are the most recent and most massive objects to have arisen in the hierarchical structure formation of the universe and the study of clusters tells one about the way galaxies form and evolve.

Clusters have two important properties: their masses are large enough to retain any energetic gas ejected from member galaxies and the thermal energy of the gas within the cluster is observable within the X-Ray bandpass.

Clusters such as the Pleiades, Hyades and a few others within about 500 light years are close enough for this method to be viable, and results from the Hipparcos position-measuring satellite yielded accurate distances for several clusters.

Clusters are also a crucial step in determining the distance scale of the universe.

He waited until 1802 ( in Catalogue of 500 new Nebulae, nebulous Stars, planetary Nebulae, and Clusters of Stars ; with Remarks on the Construction of the Heavens ) to announce the hypothesis that the two stars might be " binary sidereal systems " orbiting under mutual gravitational attraction, a hypothesis he confirmed in 1803 in his Account of the Changes that have happened, during the last Twenty-five Years, in the relative Situation of Double-stars ; with an Investigation of the Cause to which they are owing.

Clusters of galaxies should not be confused with star clusters such as galactic clusters and open clusters, which are structures within galaxies, as well as globular clusters, which typically orbit galaxies.

Clusters and large complexes of dark nebulae are associated with Giant Molecular Clouds.

Clusters of ' Black Corinth ' are small, averaging, ranging from 0. 2 to 0. 6 pounds.

A recent preliminary finding is that it can explain structure formation without CDM, but requiring a ~ 2eV massive neutrino ( They are also required to fit some Clusters of galaxies, including Bullet Cluster ) and.

Clusters of homes around old Lower Kula Road are becoming denser.

Clusters in Georgian of four, five or six consonants are not unusual — for instance, ( flat ), ( trainer ) and ( peeling )— and if grammatical affixes are used, it allows an eight-consonant cluster: ( he's plucking us ).

Clusters are made of two or more consonant sounds, while a digraph is a group of two consonant letters standing for a single sound.

The University of Kiel helped develop this radiation detector for a Mars probe. Interdisciplinary research and a university-wide infrastructure are complemented by an array of research programs that are not included in the Excellence Clusters and collaborative research centers.

His major contribution was the monumental New General Catalogue of Nebulae and Clusters of Stars ( based on William Herschels Catalogue of Nebulae ), the catalogue numbers of which are still in use, as well as two supplementary Index Catalogues.

If the Oracle database administrator has implemented Oracle RAC ( Real Application Clusters ), then multiple instances, usually on different servers, attach to a central storage array.

Through random linking between star Clusters, this construction allows universes of 5, 000 star systems or more to be generated.

He published a catalogue of his astronomical observations in 1864, as the General Catalogue of Nebulae and Clusters, a compilation of his own work and that of his father's, expanding on the senior Hershel's Catalogue of Nebulae.

In 2006, Tortoise collaborated with Bonnie ' Prince ' Billy on an album of covers entitled The Brave and the Bold, and released A Lazarus Taxon, a box set containing two CDs of single tracks and remixes, a third CD with an expanded Rhythms, Resolutions and Clusters ( long out of print ) and a DVD of videos and film of live performances.

Clusters of yellow lights on the Indo-Gangetic Plain reveal numerous cities large and small in this astronaut photograph of northern India and northern Pakistan.

Bednarik flew on 30 combat missions over Germany, for which he was awarded the Air Medal and four Oak Leaf Clusters, the European Theater Operations Medal and four Battle Stars.

Clusters of patients with Chuvash polycythemia have been found in other populations, such as on the Italian island of Ischia, located in the Bay of Naples.

The team that developed LOCUS went on to form the Locus Computing Corporation and produced various versions of the LOCUS technology under several names, culminating in the development of the UnixWare NonStop Clusters product at Tandem Computers, which had by that time acquired the LOCUS team and rights to the technology.

He served four years in the Air Force as an enlisted gunner on a B-24 Liberator, flying fifty missions over Western Europe from Italy with the 736th Bomb Squadron, 454th Bomb Group, for which he received the Air Medal with three Oak Leaf Clusters.

Clusters are allocation units for data on various file systems ( FAT, NTFS, etc.

Clusters are not directly affected by the physical or virtual geometry of the disk, i. e., a cluster can begin at a sector near the end of a given < code >< abbr title =" Cylinder "> C < abbr >< abbr title =" Head "> H </ abbr ></ code > track, and end in a sector on the physically or logically next < code >< abbr title =" Cylinder "> C < abbr >< abbr title =" Head "> H </ abbr ></ code > track.

Science News, and News Clusters on the other hand, are based on algorithms filling the content from a range of either automatically selected or manually added sources.

However, other earlier patented technologies, such as that from Manteia ( acquired by Solexa ), which generate DNA on a solid phase surface by bridge amplification-are generally referred to as " Clusters ".

Clusters are distinct in that they are based on solid-phase amplification of single DNA molecules where the DNA has been covalently attached to a surface ( e. g. Turcatti et al.

High availability clusters ( HAC ) improve application availability by failing them over or switching them over in a group of systems — as opposed to High Performance Clusters, which improve application performance by running them on multiple systems simultaneously.

Under the Excellence Initiative, a total of 37 Clusters of Excellence receive funding over a period of five years, with each Cluster of Excellence receiving an average of 6. 5 million euros per year .</ br >
