Cohen-kuhi Tau/4
CoKu Tau/4 is a pre-main-sequence binary T Tauri star system in the constellation Taurus. The stars are surrounded by a circumbinary disc with a central cavity of radius 10 astronomical units. Before its binary nature was known, the central cavity in the system's disc was thought to have been cleared out by a planet of at least 10 Jupiter masses, a rare example of a so-called "transitional disc". This model was disproven in 2008 when the star was resolved using adaptive optics as a system of two near-equal-mass stars with a projected separation This glossary of astronomy is a list of definitions of terms and concepts relevant to astronomy and cosmology, their sub-disciplines, and related fields. Astronomy is concerned with the study of celestial objects and phenomena that originate outsid ... of 8 AU. The central cavity is thus cleared out by the stars, not by the gravitational influence of a planet. References Ireland & Kraus (2008): The Disk Around CoKu Tauri/4: Circumbinary, ...

Cohen's Kappa
Cohen's kappa coefficient (''κ'', lowercase Greek kappa) is a statistic that is used to measure inter-rater reliability (and also intra-rater reliability) for qualitative (categorical) items. It is generally thought to be a more robust measure than simple percent agreement calculation, as ''κ'' takes into account the possibility of the agreement occurring by chance. There is controversy surrounding Cohen's kappa due to the difficulty in interpreting indices of agreement. Some researchers have suggested that it is conceptually simpler to evaluate disagreement between items. History The first mention of a kappa-like statistic is attributed to Galton in 1892. The seminal paper introducing kappa as a new technique was published by Jacob Cohen in the journal ''Educational and Psychological Measurement'' in 1960. Definition Cohen's kappa measures the agreement between two raters who each classify ''N'' items into ''C'' mutually exclusive categories. The definition of \kappa is :\ ...

Cohen–Macaulay Ring
In mathematics, a Cohen–Macaulay ring is a commutative ring with some of the algebraic geometry, algebro-geometric properties of a smooth variety, such as local equidimensionality. Under mild assumptions, a local ring is Cohen–Macaulay exactly when it is a finitely generated free module over a regular local subring. Cohen–Macaulay rings play a central role in commutative algebra: they form a very broad class, and yet they are well understood in many ways. They are named for , who proved the unmixedness theorem for polynomial rings, and for , who proved the unmixedness theorem for formal power series rings. All Cohen–Macaulay rings have the unmixedness property. For Noetherian local rings, there is the following chain of inclusions. Definition For a commutative noetherian ring, Noetherian local ring ''R'', a finite (i.e. Finitely generated module, finitely generated) ''R''-module M\neq 0 is a ''Cohen-Macaulay module'' if \mathrm(M) = \mathrm(M) (in general we have: \mathrm ...

The Judd School
The Judd School (often known simply as Judd) is a voluntary aided grammar school in Tonbridge, Kent, England. It was established in 1888 at Stafford House on East Street in Tonbridge, where it remained for eight years before moving to its present location on Brook Street, in the south of the town. Founded by the Worshipful Company of Skinners, it was named after 16th century merchant Sir Andrew Judde, whose endowment helped fund the school. The Skinners' Company maintains close links with the school and makes up the majority of the governing body. There are 1019 students in the school aged 11 to 18; the lower school is all boys, but of 350 students aged 16–18 in the sixth form, up to 60 are girls. The first headmaster was William Bryant, who oversaw the transition to the present site before his retirement in 1908. The current headmaster as of 2017 is Jon Wood, who replaced the previous headmaster, Robert Masters, at the start of the September 2017 year. Judd pupils general ...

Cohen Modal Haplotype
Y-chromosomal Aaron is the name given to the hypothesized most recent common ancestor of the patrilineal Jewish priestly caste known as ''Kohanim'' (singular "Kohen", also spelled "Cohen"). According to the traditional understanding of the Hebrew Bible, this ancestor was Aaron, the brother of Moses. While some early genetic studies were seen as possibly supporting the traditional biblical narrative, this view was subsequently challenged with some researchers arguing that the genetic evidence "refutes the idea of a single founder for Jewish Cohanim who lived in Biblical times." However, recent studies have provided further support for the model of descent from a common ancestor who lived in the First Temple period by demonstrating that Kohanim from different Jewish communities form a "tight cluster" which is "specific to the Jewish Cohens". The original scientific research was based on the hypothesis that a majority of present-day Jewish Kohanim share a pattern of values ...
