Phys. Lett. In pressAuthor Institution: Graduate School of Science, Tohoku UniversityDouble resonance vibrational spectroscopy is becoming a powerful spectroscopic method for the determination of molecular clusters formed in supersonic free jets. By using an advantage of high sensitivity and selectivity of electronic spectroscopy, we can measure IR and Raman spectra of the size- and isomer-selected cluster. Several spectroscopic methods will be ; IR-UV and stimulated Raman-UV double resonance spectroscopies for the clusters the electronic ground state, and UV-IR double resonance spectroscopy for the electronically excited clusters. We first demonstrate their application to the clusters in the electronically ground state, such as van der Waals clusters of and hydrogen-bonded clusters of 7-. The observed spectra are compared with those obtained by ab initio calculations, and their structures, dynamics and reactivities are discussed. We then change the subject to the OH and/or NH stretching vibrations of electronic excited molecules and their hydrogen-bonded clusters to see how the electronic excitation affects the strength of the hydrogen-bonding
ELECTRONIC SPECTRA OF CALIX[n]ARENE AND ITS VAN DER WAALS CLUSTERS IN SUPERSONIC JETS
T. Ebata, Y. Hodono, T. Ito and Y. Inokuchi, J. Chem. Phys. 126, 141101 (2007).Author Institution: Department of Chemistry, Graduate School of Science, Hiroshima University, Higashi-Hiroshima, 739-8526, JapanElectronic structure and encapsulation of neutral guest molecules have been studied for Calix[4]arene (C4A)} and Calix[5]arene (C5A) in supersonic jets. By the measurements of UV-UV hole burning and IR-UV double resonance spectra, it was found that C4A has a single isomer with C symmetry, while C5A has at least two isomers; one isomer has C symmetry while the other isomer has the structure in which one of the phenol is inverted. The ability of the encapsulation has been studied by using rare gas, nitrogen, and methane as guest molecules. The electronic spectra suggest that the first guest molecule is encapsulated inside the cavity while the next molecules are bound outside

A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
We create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
Abstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
