Tagging of Biomedical Articles on CiteULike: A Comparison of User, Author and Professional Indexing
Get PDFThis 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
On transitive linear semigroups
No full textThis paper deals with semigroups of linear transformations which act transitively on a finite-dimensional vector space. An explicit canonical form is obtained for the semigroups which lack proper transitive left ideals. The class of such semigroups can be considered to be an extention of the class of transitive groups. It contains all minimal transitive (and hence all sharply transitive) semigroups.

"At the End of an Era. The Forgotten Story of ’Jam dbyangs Mkhyen brtse Chos kyi dbang phyug. 1909-1960”
No full text'Jam dbyangs Mkhyen brtse Chos kyi dbang phyug was born in Khams, during one the most critical periods of Tibetan history. His life-story reflects the controversial and dramatic times that troubled Tibetan history before the Chinese annexation. When he was three years old, he was recognized as one of the reincarnations of the great 'Jam dbyangs Mkhyen brtse'i dbang po (1820–1892) and received an intense Buddhist education from many important masters of the time. He mainly conduced his life secluded in retreats and rediscovered several gter ma, under the name of He ka gling pa. He never wanted to get involved in the internecine feuds and rivalries for the succession to the throne of Rdzong gsar monastery. In 1930 he settled in Sde dge dgon chen but spent frequent periods as a hermit. His fame nevertheless spread widely, he became one of the most renowned and venerated bla ma of the region. In 1959 he was arrested by the Chinese PLA and brought to Sde dge prison where he died in 1960, soon after the major part of the monasteries in the Khams province had been razed to the ground.
The thread of this story is unravelled against the background of the political situation of the Khams region in the first half of the nineteenth century, where other different lives intertwine with the figure of Mkhyen brtse Chos kyi dbang phyug, casting light on the wider social, ideological and political context of the historical time
Matrix semigroups with commutable rank
No full textWe focus on matrix semigroups (and algebras) on which rank is commutable [rank(AB) = rank(BA)]. It is shown that in a number of cases (for example, in dimensions less than 6), but not always, commutativity of rank entails permutability of rank [rank(A(1)A(2)...A(n)) = rank(A(sigma(1))A(sigma(2))... A(sigma(n)))]. It is shown that a commutable-rank semigroup has a natural decomposition as a semi-lattice of semigroups that have a simpler structure. While it is still unknown whether commutativity of rank entails permutability of rank for algebras, the question is reduced to the case of algebras of nilpotents.PT: J; CR: ANDERSON FW, 1992, GRADUATE TEXTS MATH ANDO T, 1987, LINEAR ALGEBRA APPL, V90, P165 GANTMACHER FR, 1937, COMPOS MATH, P445 HORN RA, 1990, MATRIX ANAL LEVITZKI J, 1931, MATH ANN, V105, P620 LIVSHITS L, 1998, J OPERAT THEOR, V40, P35 OKNINSKI J, 1998, SERIES ALGEBRA, V6 PRASOLOV VV, 1994, PROBLEMS THEOREMS LI RADJAVI H, 2000, SIMULTANEOUS TRIANGU WHITNEY AM, 1952, J ANAL MATH, V2, P88; NR: 10; TC: 1; J9: SEMIGROUP FORUM; PG: 29; GA: 698NQSource type: Electronic(1
Completely bounded transformations of H-operator spaces
No full textAbstractIf U is the commutant of a strictly cyclic unilateral weighted shift with a monotonically decreasing weight sequence, then we show that there is a natural isomorphism of the Banach space of bounded linear maps from U into B(H) with the Banach space of bounded linear maps of the trace class operators into H, where H is a separable, infinite dimensional Hilbert space. Under this isomorphism, an operator Φ from U into B(H) is completely bounded if and only if its image extends to a bounded map of the Hilbert-Schmidt operators into H. The proof shows that if Φ is only completely row bounded, then Φ is in fact completely bounded. The characterization of the completely bounded maps is then used to prove the existence of a family of completely unbounded representations of U into B(H)
