Substructure Isomorphism Matrix
Journal of Chemical Information and Computer Sciences, 2000A substructure isomorphism matrix n x p contains binary elements describing which of the given p query structures (substructures) are part of the given n target structures (molecular structures). Such a matrix can be used to investigate the diversity of the target structures and allows the characterization and comparison of structural libraries.

Nature, 1969
RECENTLY1,2 we described “residual complexes” from calf thymus chromatin which consist of DNA and protein. We concluded from the strong binding forces that the complexes represent native substructures of the chromosomes. The proteins, although often designated as non-histones, proved to be chiefly histones which become insoluble in acids because of ...

Applied Categorical Structures, 2007
For two right \(R\)-modules \(A_R\) and \(M_R\) the following structures are considered: \(H=\Hom_R(A,M)\), \(S=\text{End}(M_R)\), \(T=\text{End}(A_R)\), where \(_SH_T\) is an \(S\)-\(T\)-bimodule. Some important subsets of \(_SH_T\) are studied (as \(S\)-\(T\)-submodules) and the relations of them with the substructures of \(A\) and \(M\) are ...

On Substructure Densities of Hypergraphs
Graphs and Combinatorics, 2009A real number \(\alpha \in [0, 1)\) is a jump for an integer \(r \geq 2\) if there exists \(c > 0\) such that for any \(\varepsilon > 0\) and any integer \(m \geq r\), there exists an integer \(n _{0}\) such that any \(r\)-uniform graph with \(n > n _{0}\) vertices and density at least \(\alpha + \varepsilon\) contains a subgraph with \(m\) vertices ...

Logic Journal of IGPL, 1994
Summary: Formal systems seem to come in two general kinds: useful and useless. This is painting things starkly, but the point is important. Formal structures can either be used in interesting and important ways, or they can languish unused and irrelevant. Lewis' modal logics are good examples.

When is a ‘‘fuzzy’’ substructure not a fuzzy substructure?
The Journal of the Acoustical Society of America, 1996A source of confusion in discussions of ‘‘fuzzy’’ substructures is use of the same term for two types of structures with different characteristics. The fuzzy substructures discussed, e.g., by Strasberg and Feit [J. Acoust. Soc. Am. 99, 335–344 (1996)] have a multitude of closely spaced, deterministic frequencies of antiresonance and sufficient damping ...

Metacompleteness of Substructural Logics
Studia Logica, 2012The paper studies the extensions of the logic \(\mathbf{FL}\) -- the logic of full Lambek calculus. A logic \(L\) is said to enjoy the disjunction property if the fact that \(\alpha \lor \beta\) is a theorem of \(L\) entails that \(\alpha\) or \(\beta\) is a theorem of \(L\).

‘Substructure’ is a collective term comprising all elements below the deck, which transfer loads to the ground below. No two bridge sites share the same ground conditions, so by definition substructure design must be bespoke for each structure. In the substructure, structural and geotechnical engineering come together, with the nature of the ground ...

Sous-structure au collisionneur de particules Dans cette thèse de doctorat, nous étudions plusieurs aspects des fonctions de distribution de partons (PDF) et des jets applicables à la physique qui sous-tend le Grand collisionneur de hadrons (LHC) ainsi que les futurs collisionneurs. Nous discutons d'abord des jets observables au LHC, en

Molecular substructure of fibrinogen
Biochemical and Biophysical Research Communications, 1963Abstract Recent studies have provided much new information on the structure of the plasma protein fibrinogen. N-terminal analyses of fibrinogen and fibrin (Blomback and Yamashina, 1958) have suggested that the native molecule is a dimer consisting of three pairs of polypeptide chains.
