In molecular biology, origin recognition complex (ORC) is a multi-subunit DNA binding complex (6 subunits) that binds in all eukaryotes and archaea in an ATP-dependent manner to origins of replication. The subunits of this complex are encoded by the ORC1, ORC2, ORC3, ORC4, ORC5 and ORC6 genes.
Topos theory is a form of abstract sheaf theory, with geometric origins, and leads to ideas such as pointless topology. Categorical logic is now a well-defined field based on type theory for intuitionistic logics , with applications in functional programming and domain theory , where a cartesian closed category is taken as a non-syntactic ...
Sketch of the Cynefin framework, by Edwin Stoop. The Cynefin framework (/ k ə ˈ n ɛ v ɪ n / kuh-NEV-in) [1] is a conceptual framework used to aid decision-making. [2] Created in 1999 by Dave Snowden when he worked for IBM Global Services, it has been described as a "sense-making device".
Dublin Core is a simple schema. MODS is far more complex. The Library of Congress maintains crosswalks in XSLT format for mapping from Dublin Core to MODS, and from MODS to Dublin Core. [3] However, no crosswalks are available for mapping between qualified Dublin Core and MODS.
A simple computation shows that the map + is a ring isomorphism from the field of complex numbers to the ring of these matrices, proving that these matrices form a field. This isomorphism associates the square of the absolute value of a complex number with the determinant of the corresponding matrix, and the conjugate of a complex number with ...
The curve complex of a surface is a complex whose vertices are isotopy classes of simple closed curves on . The action of the mapping class groups Mod ( S ) {\displaystyle \operatorname {Mod} (S)} on the vertices carries over to the full complex.
In January 2010 Kauffman joined the University of Vermont faculty where he continued his work for two years with UVM's Complex Systems Center. [16] From early 2011 to April 2013, Kauffman was a regular contributor to the NPR Blog 13.7, Cosmos and Culture, [ 17 ] with topics ranging from the life sciences, systems biology, and medicine, to ...
The complex Lie group E 8 of complex dimension 248 can be considered as a simple real Lie group of real dimension 496. This is simply connected, has maximal compact subgroup the compact form (see below) of E 8 , and has an outer automorphism group of order 2 generated by complex conjugation.
