A part of a series of four articles that examine the scientific output of different countries in biology, computer science and clean energy is presented. The U.S. leads in the scientific publications of research into clean and alternative energy, with 233,787 papers published from 2005 to 2009. Data from Elsevier's unit, SciVal Analytics showed that China is fast gaining on the U.S. when it comes to information technology publications.

The article examines the scientific output of several countries in biology, computer science and clean energy. An analysis by Elsevier division's SciVal Analytics showed that China surpassed the U.S. as the top scientific publisher about information technology in 2008 and 2009. The U.S. remained the dominant publisher in biology, medicine and clean energy areas. The article notes that U.S. publications have more influenced than Chinese research.

Purpose – The purpose of this paper is to propose an economic cybernetics model based on the grey differential equation GM(1,N) for China's high-tech industries and provide the necessary support to assist high-tech industries management departments with their policy making. Design/methodology/approach – Based on the principle of grey differential equation GM(1,N), the grey differential equations of five high-tech industries in China are established using the net fixed assets, labor quantity and patent application quantity as cybernetics variables. After the discretization and first-order subtraction reduction to the simultaneous equation of the five grey models, a linear cybernetics model is resulted in. The structure parameters in the cybernetics system show explicit economic significance and can be identified through least square principle. At last, the actual data in 2004-2010 are introduced to empirically analyze the high-tech industrial system in China. Findings – The cybernetics system for China's high-tech industries are stable, observable, and controllable. On the whole, China's high-tech industries show higher output coefficients of the patent application quantity than those of net fixed assets and labor quantity. This suggests that China's industry development mainly depends on technological innovation rather than capital or labor inputs. It is expected that the total output value of China's high-tech industries will grow at an average annual rate of 15 percent in 2011-2015, with contributions of pharmaceuticals, aircraft and spacecraft, electronic and telecommunication equipments, computers and office equipments, medical equipments and meters by 21, 16, 13, 10, and 28 percent, respectively. In addition, pharmaceuticals, as well as medical equipments and meters, present upward proportions in the gross of Chinese high-tech industries significantly. Electronic and telecommunication equipments, plus computers and office equipments exhibit an obvious decreasing proportion. The proportion of the output value of aircraft and spacecraft is basically stable. Practical implications – Empirical analysis results are helpful for related management departments to formulate reasonable industrial policies to keep the sustained and stable development of the high-tech industries in China. Originality/value – Based on the grey differential equation GM(1,N), this research puts forward an economic cybernetics model for the high-tech industries in China. This model is applicable to the economic system with small sample data set. [ABSTRACT FROM AUTHOR]

Abstract: As a newly introduced interconnection network for parallel computing, the locally twisted cube possesses many desirable properties. In this paper, mesh embeddings in locally twisted cubes are studied. Let LTQ n (V, E) denote the n-dimensional locally twisted cube. We present three major results in this paper: (1) For any integer n ⩾1, a 2×2 n−1 mesh can be embedded in LTQ n with dilation 1 and expansion 1. (2) For any integer n ⩾4, two node-disjoint 4×2 n−3 meshes can be embedded in LTQ n with dilation 1 and expansion 2. (3) For any integer n ⩾3, a 4 ×(2 n−2 −1) mesh can be embedded in LTQ n with dilation 2. The first two results are optimal in the sense that the dilations of all embeddings are 1. The embedding of the 2×2 n−1 mesh is also optimal in terms of expansion. We also present the analysis of 2p ×2q mesh embedding in locally twisted cubes. [Copyright &y& Elsevier]

The first of a four-part series of articles that examine the scientific output of several countries in biology, computer science and clean energy is presented. An analysis prepared by Elsevier division, SciVal Analytics showed that the U.S. still leads in the number of scientific research publications in reputable journals. However, Chinese researchers have outnumbered the U.S. in information technology publications in 2009. In biology and medicine, Great Britain came in second to the U.S.

The article discusses the formation of the Association for Computing Machinery (ACM) in China. Topics discussed in the article include ACM's goals to connect the computer industry within China to the rest of the world, steps that the ACM has taken to expand in other areas of the world, such as Europe, and difficulties that exist in getting China involved with the ACM.

Presents highlights of an information exchange among computer professionals in the People's Republic of China in May 1987. Conference organizers; Observation of the state of computer education and computer research in China; Schools and universities visited by the delegation to observe how computers are integrated into the classroom.

The article discusses the efforts of Jian-Wei Pan, a Chinese scientist, to develop a quantum supercomputer. A brief overview of the principles and challenges involved in using quantum mechanics for computing is presented and the international competition to create such devices is noted. The efforts of the communist Chinese government to lure top-level researchers to China are also analyzed.

The Association for Computing Machinery Executive Committee and Senior Headquarters Staff hosted an important planning meeting in Singapore on March 17, 1996. Discussion centered on issues related to computing in the Asia Pacific region, ways to facilitate the participation of people from the region in ACM, and possible new ACM programs for the region. Nine countries were represented: Australia, Hong Kong, India, Japan, Korea, New Zealand, Singapore, Taiwan and Thailand. Several of the ACM leadership in Western Europe also participated. The feasibility of a number of activities for the Asia Pacific region will be investigated. ACM would collaborate with the national societies. The organizing and program committees would be composed mainly of individuals from the region, with some participation from the U.S. and Europe. Due to the large populations of India and China and the growing interest in IT, there is significant potential for ACM in India and China. Natural "champions" to lead those efforts already exist in ACM Chapters in India and Hong Kong.

The article discusses how Chinese engineers are turning Beijing, China into a technology powerhouse. According to the author, in 2011, Chinese venture capital firms invested 13 billion dollars, 30 percent of it allocated to Beijing. The author adds that Beijing is host to exceptional concentrations of wealth as well as being a hub of higher learning, including the country's best computer science departments.
