While much empirical research has been done on the "productivity paradox" problem in the United States (for a recent survey, see Brynjolfsson 1993), Lhere has been little comparable research among newly industrializing economies (NIEs). The recent work of Krae,ner and Dedrick (1993) shows some correlation of IT investment-GDP ratio with GDP growth rate for a cross section of eleven Asia-Pacific...

Differential absorption lidar (DIAL) at the National Institute for Environmental Studies (NIES) in Tsukuba (36°N, 140°E), Japan has been making routine observation for almost 22 years. Since 1988, more than 650 vertical profiles of stratospheric ozone and temperature have been obtained. We compared the lidar data with satellite data from the Stratospheric Aerosol and Gas Experiment (SAGE II) an...

While the existing entrepreneurship literature has identified various antecedent factors that influence the intention and propensity of individuals to become entrepreneurs, there has been relatively few empirical studies covering the three East Asian NIEs of Hong Kong, Taiwan and Singapore, which have achieved among the highest average economic growth rate in the world over the last 30 years. A...

C. Calude, A. Nies, L. Staiger, and F. Stephan posed the following question about the relation between plain and prefix Kolmogorov complexities (see their paper in DLT 2008 conference proceedings): does the domain of every optimal decompressor contain the domain of some optimal prefix-free decompressor? In this paper we provide a negative answer to this question.

Microcystis aeruginosa is a problematic cyanobacterium in freshwater lakes distributed worldwide. Here, we report the draft genome sequence of M. aeruginosa NIES-87, isolated from Lake Kasumigaura, Japan. The genome is approximately 4.9 Mb in size, with an average G+C content of 42.9% and 4,355 predicted protein-coding genes.

Brattka, Miller and Nies [5] showed that some major algorithmic randomness notions are characterized via differentiability. The main goal of this paper is to characterize Kurtz randomness by a differentiation theorem on a computable metric space. The proof shows that integral tests play an essential part and shows that how randomness and differentiation are connected.
