Rational modification of a natural RNA-binding peptide with a lanthanide EDTA chelator, and a phenanthroline ligand yields a highly selective luminescent sensor. The sensing mechanism relies on the RNA-triggered folding of the peptide into a β-hairpin, which promotes the coordination of the phenanthroline sensitizer, and the efficient sensitization of complexed lanthanide ions.

We study the problem of representing a pair of algebraic lattices, L1 and L0, as Con(A1) and Con(A0), respectively, with A1 an algebra and A0 a subalgebra of A1, and we provide such a representation in a special case. Back in 1971, Ervin Fried posed the problem of representing a pair of algebraic lattices, L1 and L0, as Con(A1) and Con(A0), respectively, with A1 an algebra and A0 a subalgebra o...

We introduce a new framework for classifying logics on finite structures and studying their expressive power. This framework is based on the concept of almost everywhere equivalence of logics, that is to say, two logics having the same expressive power on a class of asymptotic measure 1. More precisely, if L, L0 are two logics and ì is an asymptotic measure on finite structures, then L a.e. L0 ...

An efficient implementation of high level model transformation languages is well known as a complex problem. It is believed that the most appropriate way to implement transformation languages is bootstrapping. However, bootstrapping is not possible without an efficient base language. In this paper, a new low level model transformation language L0+ is proposed, for which there exists an efficien...

We propose a graph-cut based image segmentation method by constructing an affinity graph using l0 sparse representation. Computing first oversegmented images, we associate with all segments, that we call superpixels, a collection of features. We find the sparse representation of each set of features over the dictionary of all features by solving a l0-minimization problem. Then, the connection i...

Five novel ruthenium(II) complexes, [Ru(dtzp)(dppt)](2+) (1), [Ru(dtzp)(pti)](2+) (2), [Ru(dtzp)(ptn)](2+) (3), [Ru(dtzp)(pta)](2+) (4) and [Ru(dtzp)(ptp)](2+) (5) (where dtzp = 2,6-di(thiazol-2-yl)pyridine, dppt = 3-(1,10-phenanthroline-2-yl)-5,6-diphenyl-as-triazine), pti = 3-(1,10-phenanthroline-2-yl)-as-triazino-[5,6-f]isatin, ptn = 3-(1,10-phenanthroline-2-yl)-as-triazino[5,6-f]naphthalene...

To investigate the flotation separation behavior of petalite and quartz, various methods were employed in this study. These included micro-flotation experiments, a contact angle analysis, zeta potential Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron (XPS) to explore mechanism modified ether amine reagent (L0-503) for quartz under weakly alkaline conditions. The test results...

We study the existence and uniqueness of global strong solutions to equations an incompressible viscoelastic fluid in a spatially periodic domain, show that unique solution exists globally time if initial deformation velocity are small for given physical parameters. In particular, can be large elasticity coefficient. Our result mathematically verifies prevent formation singularities with veloci...
