Bis(dicyanamido-κN1)bis[2-(2-hydroxyethyl)pyridine-κ2N,O]nickel(II)
Acta Crystallographica Section E, 2009 In the title complex, [Ni{N(CN)2}2(C7H9NO)2], the NiII ion (site symmetry overline{1}) adopts a distorted trans-NiO2N4 octahedral geometry. In the crystal, intermolecular O—H...N hydrogen bonds link the molecules, forming a chain along the c ...

Optimum Choice of the Front Suspension of an Automobile
Журнал інженерних наук, 2019 The paper details the optimum choice of the front suspension of an automobile. The influence of suspension on the steering geometry is studied by considering the various combinations of joints at the four-bar mechanism of the front suspension.

trans-Tris(4-bromophenyl)dichloridoantimony(V)
Acta Crystallographica Section E, 2012 The SbV atom in the title compound, [SbCl2(C6H4Br)3], has an almost regular trigonal–bipyramidal geometry with the equatorial plane made up of three C atoms of the bromophenyl groups and the axial positions occupied by two Cl− ions in

Legendrian Torus and Cable Links [PDF]
arXiv, 2021 We give a classification of Legendrian torus links. Along the way, we give the first classification of infinite families of Legendrian links where some smooth symmetries of the link cannot be realized by Legendrian isotopies. We also give the first family of links that are non-destabilizable but do not have maximal Thurston-Bennequin invariant and ...

Large N asymptotics of orthogonal polynomials, from integrability to algebraic geometry [PDF]
, 2005 In this short lecture, we compute asymptotics of orthogonal polynomials, from a saddle point approximation. This is an example of a calculation which shows the link between integrability, algebraic geometry and random matrices.Comment: Proceedings Les ...

Bis(diisopropylammonium) tetrachloridocuprate(II)
Acta Crystallographica Section E, 2012 In the title molecular salt, (C6H16N)2[CuCl4], the CuII ion adopts an extremely distorted tetrahedral coordination geometry. All the ammonium H atoms are involved in N—H...Cl hydrogen bonds, which serve to link the cations and anions into ...

, 2013 Being neither commutative nor associative, Einstein velocity addition of relativistically admissible velocities gives rise to gyrations. Gyrations, in turn, measure the extent to which Einstein addition deviates from commutativity and from associativity.

Legendrian links of topological unknots [PDF]
arXiv, 1998 We use an estimate on the Thurston--Bennequin invariant of a Legendrian link in terms of its Kauffman-polynomial to show that links of topological unknots, e.g. the Borromean rings or the Whithead link, may not be represented by Legendrian links of Legendrian unknots.

Acta Crystallographica Section E, 2011 The asymmetric unit of the title compound, [Cu(CHO2)Cl(C5H8N2)3]2·[CuCl2(C5H8N2)2] or 2[A]·[B], contains one A molecule and one half-molecule of B, located on a centre of inversion. The CuII environments in A and B are different.
