We have grown well-ordered graphene adlayers on the lattice-matched Co(0001) surface. Low-temperature scanning tunneling microscopy measurements demonstrate an on-top registry of the carbon atoms with respect to the Co(0001) surface. The tunneling conductance spectrum shows that the electronic structure is substantially altered from that of isolated graphene, implying a strong coupling between ...

BACKGROUND Phosphatidylinositol transfer protein (PI-TP), which has the ability to transfer phosphatidylinositol (PI) from one membrane compartment to another, is required in the inositol lipid signalling pathway through phospholipase C-beta (PLC-beta) that is regulated by GTP-binding protein(s) in response to extracellular signals. Here, we test the hypothesis that the principal role of PI-TP ...

is equivalent to (1.1) with 6„ = 0 (w^2) and Pi(0)p^0. The condition b„ = 0 (w^2) suggests the symmetric case, (i.e.,P„( — x) = ( —l)"P„(x)) but this is denied by the condition Pi(0) ^0. (In fact, (1.2) shows that Pn( — r)^0 whenever Pn(r)=0.) It then seems natural to ask what relations exist between a set of polynomials satisfying (1.2) and the corresponding symmetric polynomials which would b...

Debaryomyces vanrijiae MH201 produces formate oxidase (FOD) at estimated pI values by native isoelectric focusing of 5.1, 5.4, and 5.9. We cloned and expressed three formate oxidase cDNAs, FOD1, FOD2, and FDO3, of the yeast using Escherichia coli. The open reading frames of FOD1, FOD2, and FDO3 were 1,731 bp long, and encoded 576-amino acid polypeptides with molecular masses of 64,142, 63,794, ...

In this paper some upper and lower bounds for the greatest eigenvalues of the PI and vertex PI matrices of a graph G are obtained. Those graphs for which these bounds are best possible are characterized.

Biomimetic Soft Robots The combination of photo-thermal effect Au and the mismatch between thermal expansion coefficients LDPE film PI adhesive has enabled design sandwich-structured photo-responsive PI/Au/LDPE nanocomposite film. Thanks to its dexterous geometry design, stable reversible actuation behavior, remote precise driven mode, biomimetic soft robots with pre-engineered functionality co...

Oxysterol binding protein (OSBP) and OSBP-related proteins (ORPS) have a conserved lipid-binding fold that accommodates cholesterol, oxysterols and/or phospholipids. The diversity of OSBP/ORPs and their potential ligands has complicated the analysis of transfer and signalling properties of this mammalian gene family. In this study we explored the use of the fluorescent sterol cholestatrienol (C...

Despite the growing knowledge concerning allelopathic interference with barnyard grass, little is understood regarding competitive physiological mechanisms of interaction between rice and herbicide-resistant grass. A hydroponic system was employed to investigate root morphological traits different phytohormonal changes in non-allelopathic cultivars when co-planted quinclorac-resistant -suscepti...
