Microdetermination of Methyl Groups Attached to Carbon

Metric groups attached to biextensions

Let G be a connected, unipotent, perfect group scheme over an algebraically closed field of characteristic p > 0 and let E be a biextension (cf. [SGA7tI], exp. VII, no. 1) of G ×k G by the discrete group Qp/Zp. When E is skewsymmetric (cf. sec. 3.1), V. Drinfeld defined in [Dr] a certain metric group A (cf. appendix) associated to E. In this article, we prove a conjecture stated in [Dr] (cf. se...

Motivic interpretation of Milnor K-groups attached to Jacobian varieties

In the paper [Som90] p.105, Somekawa conjectures that his Milnor Kgroup K(k, G1, . . . , Gr) attached to semi-abelian varieties G1,. . . ,Gr over a field k is isomorphic to ExtrMk (Z, G1[−1] ⊗ . . . ⊗ Gr[−1]) where Mk is a certain category of motives over k. The purpose of this note is to give remarks on this conjecture, when we take Mk as Voevodsky’s category of motives DM (k) .

3D characterization of CdSe nanoparticles attached to carbon nanotubes

The crystallographic structure of CdSe nanoparticles attached to carbon nanotubes has been elucidated by means of high resolution transmission electron microscopy and high angle annular dark field scanning transmission electron microscopy tomography. CdSe rod-like nanoparticles, grown in solution together with carbon nanotubes, undergo a morphological transformation and become attached to the c...

On the rank of Picard groups of modular varieties attached to orthogonal groups

Carbon atom 2 of L-histidine-2-C14, a source of the carbon of labile methyl groups in liver.

Data presented in this report point to carbon at.om 2 of L-histidine as an important source of the carbon of labile methyl groups. The results obtained in direct studies of the isolated perfused normal and cirrhotic rat liver are qualitatively and quantitatively similar t,o those obtained with intact normal rats and rats kept on a choline-deficient diet (1) for a short time (10 days) and a long...
