The magnetic field dependences of the magnetization (B≤9 T, T=2-70 K) samples from a single crystal Pb 1-y Sc y Te (y=0.01) ingot, synthesized by Bridgman method, are studied. It is established that, in accordance with generally accepted model rearrangement electronic structure alloys during doping, there no paramagnetic contribution scandium ions located nodes metal sublattice studied samples....

Air-stable organic radicals and radical ions have attracted great attention for their far-reaching application ranging from bioimaging to electronics. However, because of the highly reactive nature radicals, design synthesis air-stable still remains a challenge. Herein, an controllable photoinduced domino reaction hexa-aryl substituted anthracene is described. The involves [4 + 2] cycloaddition...

Developmentally regulated V(D)J recombination profoundly influences immune repertoires, but the underlying mechanisms are poorly understood. In the endogenous T cell receptor Cgamma1 cluster, the 3' Vgamma3 gene (closest to Jgamma1) rearranges preferentially in the fetal period whereas rearrangement of the 5' Vgamma2 gene predominates in the adult. Reversing the positions of the Vgamma2 and Vga...

OBJECTIVE To evaluate the usefulness of morphologic diagnosis, immunophenotyping and immunoglobulin (Ig) and T-cell receptor (TcR) gene rearrangement studies in the diagnosis of lymphoproliferative disorder. DESIGN A retrospective cohort study with clinical follow-up of controversial cases. SETTING Single institution, tertiary care centre. PATIENTS All 273 patients whose lymphoid tissue s...

Rearrangement reactions are a very powerful tool for the conversion of simple substrates into highly functionalized products in organic chemistry. In combination with an attractive initiation process, such as visible-light catalysis, these particularly powerful. Read more about recent progress on aryl migration reactions, focusing especially Smiles rearrangement and related Review by E. Brachet...

The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Current research in materials has devoted much attention to graphene, with a considerable amount of the chemical manipulation going through the oxidized state of the material, known as graphene oxide (GO). In this report, the hydroxyl functionalities in GO, the vast majority th...

The difference between genome rearrangement theory and other approaches to comparative genomics, and indeed most other topics in computational molecular biology, is that it is not directly based on macromolecular sequences, either nucleic acids or proteins. Rather like classical genetics, its building blocks are genes, and the structures of interest are chromosomes, abstracted in terms of the l...
