Guanosine diphosphate esterified at the beta-phosphate group with the photolabile 4-azidophenol [1-(4-azidophenyl)-2-(5'-guanyl)pyrophosphate] was found to inhibit GDP binding to the ribosomes of E. coli. UV-irradiation of the fusidic acid-stabilized complex among ribosomes, elongation factor G, and the azidophenyl-GDP, results in selective attachment of the photo-affinity label to the proteins...

Source coding based on Gaussian Mixture Models (GMM) has been recently proposed for LPC quantization. We address in this paper the related problem of designing efficient codebooks for Gaussian vector sources. A new technique of ellipsoidal lattice vector quantization (VQ) is described, based on 1) scalar companding optimized for Gaussian random variables and 2) rectangular lattice codebooks wit...

This paper explores the relationship between patterns of productivity growth and the development stage of an industry, using firm-level data on the cotton-spinning industry in Japan in the late-nineteenth century. It is found that patterns of productivity growth depend on the development stage of the industry. In the earlier stage of industrial development, the productivity growth of each firm,...

In the present work, ribosomes assembled in bacterial cells in the absence of essential ribosomal protein L5 were obtained. After arresting L5 synthesis, Escherichia coli cells divide a limited number of times. During this time, accumulation of defective large ribosomal subunits occurs. These 45S particles lack most of the central protuberance (CP) components (5S rRNA and proteins L5, L16, L18,...

Using 1959—1991 growth rates for 449 4-digit US manufacturing industries, I test ‘idea’ and ‘rival human capital’ models of endogenous growth. I find the following: First, TFP growth is faster in industries that are more intensive in capital and intermediate goods and less intensive in labor, favoring idea models over rival human capital models. Second, industries with rapidly declining prices ...

Abstract: The study has been carried out to investigate the effects of single factors such as temperature, extraction time, concentration of ethanol, material ratio and no. of extractions on the contents of flavonoids present in the leaves of Tabernaemontana heyneana Wall. were investigated in this study. On this basis, an L16 orthogonal design of experiment was adopted to determine the optimal...

This paper presents the application of the Taguchi experimental design in developing nanostructured yittria stabilized zirconia (YSZ) coatings by plasma spraying process. This paper depicts dependence of adhesion strength of as-sprayed nanostructured YSZ coatings on various process parameters, and effect of those process parameters on performance output has been studied using Taguchi's L16 orth...

We develop a tractable dynamic general equilibrium model of oligopolistic competition with a continuum of heterogeneous industries. Industries are exposed to aggregate and industry-specific productivity shocks. Firms in each industry set value-maximizing state-contingent markups, taking as given the behavior of all other industries. When consumers are risk-averse, industry markups are countercy...

50S-derived cores were prepared by treatment of 50S subunits with 0.4 M Licl (0.4c core) and 0.8 M Licl (0.8c core), respectively. 0.4c cores bind chloramphenicol whereas 0.8c cores do not. The split proteins obtained during the transitions 0.4c --> 0.8c were separated by DEAE-cellulose chromatography and Sephadex G-100 gel filtration. Reconstitution experiments with the fractionated proteins d...
