a label-free electrochemical nucleic acid aptasensor for the detection of methamphetamine (ma) by the immobilization of thiolated self-assembled dna sequences on a gold nanoparticles-chitosan modified electrode is constructed. when ma was complexed specifically to the aptamer, the configuration of the nucleic acid aptamer switched to a locked structure and the interface of the biosensor changed...

Replacing associated consistency in Hamiache’s axiom system by dual similar associated consistency, we axiomatize the Shapley value as the unique value verifying the inessential game property, continuity and dual similar associated consistency. Continuing the matrix analysis for Hamiache’s axiomatization of the Shapley value, we construct the dual similar associated game and introduce the dual ...

Filtering techniques are essential to e ciently look for a so lution in a constraint network CN They remove some local inconsisten cies and so reduce the search space However a given local consistency has to be not too expensive if we want to use it to e ciently prune the search tree during search Hence for a long time it has been considered that the best choice is the limited local consistency...

Linearizability, the de facto correctness condition for concurrent data structure implementations, despite its intuitive appeal is known to lead to poor scalability. This disadvantage has led researchers to design scalable data structures satisfying consistency conditions weaker than linearizability. Despite this recent trend, sequential consistency as a strictly weaker consistency condition th...

Abstract We analyze the physical content of squeezed bispectra involving long-wavelength tensor perturbations, showing that these modes cannot be gauged away, except for exact (unphysical) limit infinite wavelength, k = 0. This result has a direct implication on validity Maldacena consistency relation, respected by subclass inflationary models. Consequently, in limit, as case scalar-scalar-scal...

We introduce a bilevel problem of the optimal control an interacting agent system that can be interpreted as Stackelberg game with large number followers. It is shown model well posed by providing conditions allow to formally reduce single level unconstrained problem. The mean-field limit derived for infinitely many followers at three different stages optimization and commutativity these operat...

In a certain strong coupling limit, compactification of the E8 ×E8 heterotic string on a Calabi-Yau manifold X can be described by an eleven-dimensional theory compactified on X × S/Z2. In this limit, the usual relations among low energy gauge couplings hold, but the usual (problematic) prediction for Newton’s constant does not. In this paper, the equations for unbroken supersymmetry are expand...

in this research, air sampling of workplaces was carried out by two methods (long - time and short - time). the mean formaldehyde concentration with long - time method in pathology labs, surgery and endoscopy sections were 0.96 0.25 and 0.13 ppm and with short - time method, 8 hours, was 3, 0.3 and 0.2 ppm. the mean formaldehyde concentration in pathology labs was above the standard values (tlv...
