Stereotypically, computation involves intrinsic changes to the medium of representation: writing new symbols, erasing old symbols, turning ears, flipping switches, sliding abacus beads. Perspectival computation leaves the original inscriptions untouched. The problem solver obtains the output by merely alters his orientation toward the input. There is no rewriting or copying of the input inscrip...
A simple extractive spectrophotometric method has been developed for the estimation of miconazole nitratein both pure and pharmaceutical preparation. The method is based on the formation of ion-pair complex of thedrug with acidic dye bromothymol blue (BTB) in acidic condition, followed by its extraction in organic solvent(chloroform). The absorbance was measured against the corresponding blank....
We consider the general process of pair-creation of charged rotating black holes. We find that instantons which describe this process are necessarily complex due to regularity requirements. However their associated probabilities are real, and fully consistent with the interpretation that the entropy of a charged rotating black hole is the logarithm of the number of its quantum states. Black hol...
An easily-accessible neutral scandium complex Sc[OC(CH3)2CH2PPh2][O-2,6-tBu2-C6H3]2[THF] behaves as a reactive Sc/P frustrated Lewis pair, which when added to organic and inorganic substrates e.g. carbonyl compounds, transition-metal chlorides, and diazoalkane compounds, yields unique and intriguing addition products such as a Sc/Rh heterobimetallic complex and a Sc phosphazine complex.
Nisoldipine, a 1-4-dihydropyridine drug is determined by the development of simple and sensitive Extractive Spectrophotometric method. In the present study an ion-pair complex of amino derivative of the Nisoldipine with Bromocresol Green Solution in acidic medium is formed with subsequent extraction of the ion-pair complex in Chloroform. Maximum absorption was seen at the wavelength of 418 nm t...
Evolutionary games on networks have recently attracted attention in evolutionary biology, behavioral science and statistical physics. In particular, an intensively studied question is how network structure influences the evolution of cooperative behavior in a dilemma situation (for regular lattices1)–6) and complex networks7)–14)). Nowak and May observed that cooperation behavior can be enhance...
In this article, we consider pair frames in Banach spaces and introduce Banach pair frames. Some various concepts in the frame theory such as frames, Schauder frames, Banach frames and atomic decompositions are considered as special kinds of (Banach) pair frames. Some frame-like inequalities for (Banach) pair frames are presented. The elements that participant in the construction of (Ba...
