Three (bola)amphiphilic spirooxazines have been synthesized and their photochromism has been characterized. The large biphotochromic structure of 2 significantly affects its conformational flexibility and the rate constants for thermal ring closure are particularly dependent on the lipid phase state. Two comprehensive ion permeation studies were performed to examine the effect of spirooxazine i...

The cyclodextrin solubilization of three benzodiazepines, i.e. alprazolam, midazolam and triazolam, was investigated. The cyclodextrin solubilization was enhanced through ring-opening of the benzodiazepine rings and ionization of the ring-open forms. Additional enhancement was obtained through interaction of a water-soluble polymer with the cyclodextrin complexes. The ring-opening was pH-depend...

Adders and multipliers are two main units of the computer arithmetic processors and play an important role in reversible computations. The binary multiplier consists of two main parts, the partial products generation circuit (PPGC) and the reversible parallel adders (RPA). This paper introduces a novel reversible 4×4 multiplier circuit that is based on an advanced PPGC with Peres gates only. Ag...

reversible logic circuits have found emerging attentions in nanotechnology,optical computing, quantum computing and low power design. a programmablelogic array (pla) is a universal circuit which is used to implement combinationallogic circuits. the main part of a pla is its and array. in this study we propose twotypes of optimized reversible programmable logic array (rpla) circuits. the firstty...

Carbon nanotube (CNT)-based materials allow for the direct conversion of light into heat and then mechanical force in so-called photo-mechanical effect. This effect has been observed almost solely form polymer (nano)composites, where CNTs act as active fillers. To overcome issue with heterogeneous distribution, hybrids based on multiwalled carbon nanotubes (MWCNTs) covalently modified poly(2-hy...

In this paper, we give a matrix construction method for designing DNA codes that come from group rings. We show with our one can obtain reversible $$G^k$$ -codes of length kn, where $$k, n \in \mathbb {N},$$ over the finite commutative Frobenius ring R. employ to many $$\mathbb {F}_4$$ satisfy Hamming distance, reverse, reverse-complement and fixed GC-content constraints. Moreover, improve lowe...

In this paper, we show that one can construct a \begin{document}$ G $\end{document}-code from group rings is reversible. Specifically, given with subgroup of order half the ambient an element its own inverse outside subgroup, give ordering elements for which id="M4">\begin{document}$ $\end{document}</tex-...
