We examined the enhancement effects of the double-chained cationic surfactants of n-dimethyldialkylammoniums (CH(3))(2)N(+)(C(n)H(2n+1))(2) on the permeation of anionic salicylate through excised guinea pig dorsal skin at pH 7.4. Among them, n-dimethyldidecylammonium (2C10), which seemed to form micelles, had dose-dependent enhancement effects at concentrations of more than 0.1 mM, and about a ...

The formation of mixed shell-by-shell (SbS) systems with tunable shell compositions is demonstrated by using molecular self-assembly driven chemical recognition motifs. Aluminum oxide nanoparticles (AlOx-NPs) act as template surface for a self-assembled monolayer (SAM) either partially fluorinated fluoroalkyl or alkyl chained phosphonic acid derivatives defined stoichiometric mixtures those. By...

In this paper, we develop the machinery of exterior diierential forms, more particularly the Goursat normal form for a Pfaaan system, for solving nonholonomic motion planning problems, i.e. planning problems with non-integrable velocity constraints. We apply this technique to solving the problem of steering a mobile robot with n trailers. We present an algorithm for nding a family of transforma...

We consider a special type of integer partitions in which the parts of the form pq, for some relatively prime integers p and q, are restricted by divisibility conditions. We investigate the problems of generating and encoding those partitions and give some estimates for several partition functions.

In this work, we present an adaptation of the sequence-tosequence model for structured vision tasks. In this model, the output variables for a given input are predicted sequentially using neural networks. The prediction for each output variable depends not only on the input but also on the previously predicted output variables. The model is applied to spatial localization tasks and uses convolu...
