Variational Symplectic Structures
2017A variational symplectic structure on an equation \(\mathcal {E}\) is a \(\mathcal {C}\)-differential operator \(\mathcal {S}\colon \varkappa = \mathcal {F}(\mathcal {E};m)\to \hat {P} = \mathcal {F}(\mathcal {E};r)\) that takes symmetries of \(\mathcal {E}\) to cosymmetries and enjoys additional integrability properties.

Structural Variation in Subtelomeres
2011Subtelomeres are an incredibly dynamic part of the human genome located at the ends of chromosomes just proximal to telomere repeats. Although subtelomeric variation contributes to normal polymorphism in the human genome and is a by-product of rapid evolution in these regions, rearrangements in subtelomeres can also cause intellectual disabilities and ...

Structural Variation in PWWP Domains
Journal of Molecular Biology, 2003The PWWP domain is a ubiquitous eukaryotic protein module characterised by a region of sequence similarity of approximately 80 amino acids containing a highly conserved PWWP motif. It is frequently found in proteins associated with chromatin. We have determined the structure of a PWWP domain from the S. pombe protein SPBC215.07c using NMR spectroscopy.

Structural variations among the kinesins
Trends in Cell Biology, 1995Members of the kinesin family of motor proteins are assembled from kinesin-related polypeptides that share conserved 'motor' domains linked to diverse 'tail' domains. Recent work suggests that tail diversity underlies the differences in quaternary structure observed among native kinesin holoenzymes.

Variational Poisson Structures
2017A variational Poisson structure on a differential equation \(\mathcal {E}\) is a \(\mathcal {C}\)-differential operator that takes cosymmetries of \(\mathcal {E}\) to its symmetries and possesses the necessary integrability properties. In the literature on integrable systems, Poisson structures are traditionally called Hamiltonian operators.

Structural Variations of Potassium Aryloxides
Inorganic Chemistry, 2003A series of potassium aryloxides (KOAr) were isolated from the reaction of a potassium amide (KN(SiMe(3))(2)) and the desired substituted phenoxide (oMP, 2-methyl; oPP, 2-iso-propyl; oBP, 2-tert-butyl; DMP, 2,6-di-methyl; DIP, 2,6-di-iso-propyl; DBP, 2,6-di-tert-butyl) in tetrahydrofuran (THF) or pyridine (py) as the following: [([K(mu(4)-oMP)(THF)][K ...

Structural Chromosomal Variations in Neurological Diseases
The Neurologist, 2009Significant advancement in the identification of genetic mutations and molecular pathways underlying Mendelian neurologic disorders was accomplished by using the methods of linkage, gene cloning, sequencing, mutation, and functional analyses, in the 1990s.

Structural Genomic Variation and Personalized Medicine
New England Journal of Medicine, 2008Large-scale genomic deletions, duplications, and inversions represent a major source of variation among persons; thus, new approaches to probing disease susceptibility are warranted.

Invariant Variational Structures
2015Let X be any manifold, W an open set in X, and let α: W → X be a smooth mapping. A differential form η, defined on the set α(W) in X, is said to be invariant with respect to α, if the transformed form \( \alpha \ast \eta \) coincides with η, that is, if \( \alpha \ast \eta = \eta \) on the set \( W \cap \alpha (W) \); in this case, we also say that α ...
