On the unitarity of stochastic evolutions driven by the square of white noise
No full textUsing the closed Ito's table for the renormalized square of white
noise, recently obtained by Accardi, Hida, and Kuo in Ref. 4, we
consider the problem of providing necessary and sufficient conditions
for the unitarity of the solutions of a certain type of quantum
stochastic differential equations
Symbol-Flipping Based Decoding of Generalized Low-Density Parity-Check Coded Constructed over GF(q)
No full textAn efficient symbol-flipping based decoding algorithm designed for nonbinary Generalized Low-Density Parity-Check (GLDPC) codes is proposed. By extending the concept of the Weighted Bit Flip Voting (WBFV) algorithm designed for binary Hamming-code based GLDPC codes, the symbol-flipping decoding algorithm can be beneficially employed for decoding the family of GLDPC codes constructed from nonbinary constituent codes, such as nonbinary Bose Chaudhuri Hocquenghem (BCH) codes or Reed Solomon (RS) codes. The simulation results demonstrate that improvements of 1 dB and 2.7 dB are achieved by the proposed coding scheme in comparison to the more conventional binary GLDPC codes using the WBFV decoding algorithm, when using the Galois Field GF(32) for communicating over AWGN and uncorrelated Rayleigh fading channels, respectively
Note on Kuo′s Problem
No full textAbstractFor the eigenvalue problem of H. L. Kuo [J. Met.6 (1949), 105-122] governing the linear stability of a parallel zonal flow of an inviscid, incompressible fluid on a β-plane, it is shown that the wave velocity of neutral modes is bounded. Moreover, Pedlosky′s semicircle region for the range of the complex wave velocity of an arbitrary unstable mode is further reduced
Location Choice of Multinational Enterprises in China: Comparison between Japan and Taiwan
No full textThis paper explores the location choice of MNEs in China, shedding special light on the role of agglomeration of same-nationality firms. In particular, we examine how its role differs according to investors’ productivity. Furthermore, we compare the location choice of Japanese and Taiwanese MNEs in China, because Taiwanese MNEs are expected to experience less uncertainty in investing in China than Japanese MNEs, due to Taiwan’s linguistic and cultural advantages in China. We find that, less productive Japanese firms prefer to locate close to larger same-nationality agglomerations, there are no differences in location according to firms’ productivity in the case of Taiwanese firms.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
