Intrinsic topological insulators are realized by alloying Bi(2)Te(3) with Bi(2)Se(3). Angle-resolved photoemission and bulk transport measurements reveal that the Fermi level is readily tuned into bandgap. First-principles calculations of native defect landscape highlight key role anti-site defects for achieving this, predict optimal growth conditions to realize maximally resistive insulators.
We describe a murine cDNA, designated Early T lymphocyte activation 1 (ETA-1) which is abundantly expressed after of cells. Eta-1 encodes highly acidic secreted product having structural features proteins that bind to cellular adhesion receptors. The gene maps locus on chromosome 5 termed Ric confers resistance infection by Rickettsia tsutsugamushi (RT), an obligate intracellular bacterium the etiological agent for human scrub typhus. With one exception, inbred mouse strains Eta-1a allele...
The Eta-1 gene specifies a secreted product of activated T cells and is associated with genetic resistance to infection by an obligate intracellular bacterium. Previous studies have suggested that eta-1 might affect the ability macrophages migrate site bacterial and/or inhibit growth. We therefore examined interaction in vitro vivo. find express approximately 10(4) receptors/cell each receptor has Kd 5 x 10(-10) M. subsequence containing RGD motif required for binding because synthetic...
We have investigated the superconducting state of noncentrosymmetric compound Re6Zr using magnetization, heat capacity, and muon-spin relaxation or rotation (μSR) measurements. has a transition temperature, Tc=6.75±0.05 K. Transverse-field μSR experiments, used to probe superfluid density, suggest an s-wave character for gap. However, zero longitudinal-field data reveal presence spontaneous static magnetic fields below Tc indicating that time-reversal symmetry is broken in unconventional...
The superconductivity of the noncentrosymmetric compound La(7)Ir(3) is investigated using muon spin rotation and relaxation. Zero-field measurements reveal presence spontaneous static or quasistatic magnetic fields below superconducting transition temperature T(c)=2.25 K-a clear indication that state breaks time-reversal symmetry. Furthermore, transverse-field suggest gap isotropic pairing symmetry electrons predominantly s wave with an enhanced binding strength. results indicate in may be...
To trace the origin of time-reversal symmetry breaking (TRSB) in Re-based superconductors, we performed comparative muon-spin rotation/relaxation ($\mu$SR) studies superconducting noncentrosymmetric Re$_{0.82}$Nb$_{0.18}$ ($T_c = 8.8$ K) and centrosymmetric Re 2.7$ K). In Re$_{0.82}$Nb$_{0.18}$, low temperature superfluid density electronic specific heat evidence a fully-gapped state, whose enhanced gap magnitude specific-heat discontinuity suggest moderately strong electron-phonon coupling....

Here, flexible production process discussed under imprecise market conditions partial backlogging rework. Two different models are presented here by considering costs....
The Rpt-1 (for regulatory protein, T-lymphocyte, 1) gene, selectively expressed by resting but not activated CD4+ inducer T cells, encodes an intracellular protein (rpt-1, Mr 41,000) that down-regulates gene expression directed the promoter region of encoding interleukin 2 receptor alpha chain and long terminal repeat human immunodeficiency virus type 1. data reported here suggest rpt-1 levels may be inversely correlated with activation cells replication leading to clinical symptoms acquired...

The discovery of new families unconventional superconductors is important both experimentally and theoretically, especially if it challenges current models thinking. By using muon spin relaxation in zero field, time-reversal symmetry breaking has been observed ${\mathrm{Re}}_{6}\mathrm{Hf}$. Moreover, the temperature dependence superfluid density exhibits $s$-wave superconductivity with an enhanced electron-phonon coupling. This, coupled results from isostructural...

We have investigated the superconducting state of noncentrosymmetric superconductor ${\mathrm{Re}}_{6}\mathrm{Ti}$ (${T}_{c}=6.0$ K) using a muon-spin rotation/relaxation technique. The zero-field muon experiment shows presence spontaneous magnetic fields in state, indicating time-reversal symmetry breaking (TRSB). However, low-temperature transverse-field measurements suggest nodeless $s$-wave superconductivity. Similar results were also observed for ${\mathrm{Re}}_{6}X$ ($X=\text{Zr}$, Hf)...
