a series of 2-amino-4-aryl-3-cyano-7-(dimethylamino)-4 h -chromenes was synthesized by condensation of 3-(dimethylamino)phenol, an aromatic aldehyde and malonitrile in ethanol containing piperidine. the assignments of the structure of all synthesized compounds were based on spectral data (ir, mass and 1 h nmr). the cytotoxic activities of the synthesized compounds against six human tumor cell l...
This report provides data of the automatic acoustic synthesis of basic German vowel phoneme allophones with the use of one channel fonnant synthesizer; analyzed herein are the acoustic parameters of natural German vowels obtained from sonagrammes of sounds produced by a native speaker; provided are the data on formant characteristics of the synthesized vowel sound-types suggestive of their perc...
A major problem with low-level functional verii-cation of any hierarchical system is the explosion of reachable states created when clocking mechanisms are incorporated into the model. These additional states make veriication more diicult, usually to the point that veriication at such a low level is not feasible. Transforms have been developed to take a nonhierarchi-cal model with a complex clo...

Abstract Polyhydroxyalkanoates (PHA) produced by many bacteria have been investigated by microbiologists, molecular biologists, biochemists, chemical engineers, chemists, polymer experts, and medical researchers over the past many years. Applications of PHA as bioplastics, fine chemicals, implant biomaterials, medicines, and biofuels have been developed. Companies have been established or invol...
We study a novel class of open-loop control protocols constructed to perform arbitrary nontrivial single-qubit logic operations robust against time-dependent non-Markovian noise. Amplitude and phase modulation protocols are crafted leveraging insights from functional synthesis and the basis set of Walsh functions. We employ the experimentally validated generalized filter-transfer function forma...
