Etymology. Chthamalus williamsi is named in honour of Prof. Gray A. Williams, Director of the Swire Institute of Marine Sciences, School of Biological Science, the University of Hong Kong, for life-long friendship and mentorship with the first author and for his contributions to the intertidal ecology in the South China Sea. Distribution. Chthamalus williamsi sp. nov. is common inside crevices of the mid shore of the intertidal zone, and on the shell surfaces of the barnacle Megabalanus volcano (Pilsbry, 1916) and M. tintinnabulum (Linnaeus, 1758) on low shores of the eastern waters of Taiwan. Chthamalus williamsi has not been identified previously from Taiwan as it is not easily spotted, due to its small size and low shore location. This species is absent from the N and NE coasts of Taiwan although intensive sampling was conducted (Fig. 1), suggesting its distribution may be associated with the Kuroshio Current. Molecular analysis. From both maximum likelihood and Bayesian inference trees of a COI region, Chthamalus williamsi shows a distinct divergence from C. challengeri, C. dalli, C. moro, C. malayensis and C. sinensis (sequence divergence> 0.13 K 2 P distance from all the Chthamalus species compared; Table 1). Chthamalus sinensis and C. neglectus grouped in the same clade, suggesting C. neglectus is a synonym of C. sinensis (see Liu & Ren 2007 for synonyms of C. neglectus and C. sinensis).Published as part of Chan, Benny K.

Positive definite almost regular ternary quadratic forms over totally real number fields
No full textChan, WK (reprint author), Wesleyan Univ, Dept Math & Comp Sci, Middletown, CT 06459 USA. Icaza, MI. Univ Talca, Inst Matemat & Fis, Talca, ChileLet F be a totally real number field and let be the ring of integers in F. A totally positive quadratic form f over is said to be almost regular with k exceptions if f represents all but k elements in F that are represented by f locally everywhere. In this paper, we show that for a fixed positive integer k, there are only finitely many similarity classes of positive definite almost regular ternary quadratic forms over with at most k exceptions. This generalizes the corresponding finiteness result for positive definite ternary quadratic forms over by Watson (PhD Thesis, University College, London, 1953; Mathematika 1 (1954) 104-110)
Remarks on the k-error linear complexity of p(n)-periodic sequences
No full textRecently the first author presented exact formulas for the number of 2ⁿn-periodic binary sequences with given 1-error linear complexity, and an exact formula for the expected 1-error linear complexity and upper and lower bounds for the expected k-error linear complexity, k >2, of a random 2ⁿn-periodic binary sequence. A crucial role for the analysis played the Chan-Games algorithm. We use a more sophisticated generalization of the Chan-Games algorithm by Ding et al. to obtain exact formulas for the counting function and the expected value for the 1-error linear complexity for pⁿn-periodic sequences over Fp, p prime. Additionally we discuss the calculation of lower and upper bounds on the k-error linear complexity of pⁿn-periodic sequences over Fp

Tagging of Biomedical Articles on CiteULike: A Comparison of User, Author and Professional Indexing
No full textThis paper examines the context of online indexing from the viewpoint of three different groups: users, authors, and professional indexers. User tags, author keywords and descriptors were collected from academic journal articles, which were both indexed in Pubmed and tagged on CiteULike, and analysed. Descriptive statistics, informetric measures, and thesaural term comparison shows that there are important differences in the use of keywords between the three groups in addition to similarities which can be used to enhance support for search and browse. While tags and author keywords were found that matched descriptors exactly, other terms which did not match but provided important expansion to the indexing lexicon were found. These additional terms could be used to enhance support for searching and browsing in article databases as well as to provide invaluable data for entry vocabulary and emergent terminology for regular updates to indexing systems. Additionally, the study suggests that tags support organisation by association to task, projects and subject while making important connections to traditional systems which classify into subject categories
