HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau...

It is a pleasure to be able to introduce this second Thematic Series on ‘organo-fluorine chemistry’ within the Beilstein Journal of Organic Chemistry. The series now embeds the subject firmly as a special interest area of the journal. The first series in 2008 presented contributions representing a wide range of organic fluorine chemistry [1-10] and this series continues that trend exploring the...

Vacancies play a pivotal role in affecting ferroelectric polarization and switching properties, and there is a possibility that ferroelectricity may be utterly eliminated when defects render the system metallic. However, sufficient quantitative understandings of the subject have been lacking for decades due to the fact that vacancies in ferroelectrics are often charged and polarization in charg...

Over the past 40 years, much of the author's research, both computational and experimental, has involved collaborations. This Perspective describes some of the author's collaborative research in eight different areas of organic and theoretical chemistry: (1) hydrocarbons containing unsaturatively, 1,3-bridged cyclobutane rings, (2) the use of orbital topology for predicting the ground states of...

OBJECTIVE 3-Deoxyglucosone (3-DG), a highly reactive intermediate of the glycation reaction, has been suggested to contribute to the development of diabetes complications. To verify this hypothesis, we assessed the relation between serum 3-DG concentrations and the severity of diabetic microangiopathy in diabetic patients. RESEARCH DESIGN AND METHODS We conducted a high-performance liquid chr...

Let F be a polystable sheaf on smooth minimal projective surface of Kodaira dimension 0. Then the DG-Lie algebra RHom(F,F) derived endomorphisms is formal. The proof based study equivariant $L_{\infty}$ models algebras equipped with cyclic structure degree 2 which non-degenerate in cohomology, and does not rely (even for K3 surfaces) previous results same subject.

Theorem. Any compact Riemann surface may be minimally immersed in S. To prove this, Bryant considers the Penrose fibration π : CP 3 → S = HP . The perpendicular complement to the fibres (with respect to the Fubini-Study metric) furnishes CP 3 with a holomorphic distribution H ⊂ T CP 3 and it is well-known that a holomorphic curve in CP 3 tangent to H (a horizontal holomorphic curve) projects on...

We prove that if G = (VG, EG) is a finite, simple, and undirected graph with κ components and independence number α(G), then there exist a positive integer k ∈ N and a function f : VG → N0 with non-negative integer values such that f(u) ≤ dG(u) for u ∈ VG, α(G) ≥ k ≥ ∑ u∈VG 1 dG(u)+1−f(u) , and ∑ u∈VG f(u) ≥ 2(k − κ). This result is a best-possible improvement of a result due to Harant and Schi...
