Historic marine invertebrate species inventory: case study of a science baseline towards establishing a marine conservation area
Authors: Sloan N.A. , Bartier P.M. 
Published: February 2009

Abstract
Assessing species diversity is a basic requirement for conservation, and protecting biodiversity is a major goal of marine area conservation.
A case study is presented on the development of a literature‐based (1870s to 2000), museum collection‐based, georeferenced inventory of marine invertebrate species of the Haida Gwaii (Queen Charlotte Islands) region, Canada.
Database structure and quality assurance are described, along with including indigenous people's words for species towards using traditional knowledge within cooperative marine conservation area management.
The utility of this type of inventory is proposed as a starting point for gathering regional biodiversity knowledge, and facilitating addition of other knowledge types, towards marine area conservation.

AbstractThe increasing complexity of human body models enabled by advances in diagnostic imaging, computing, and growing knowledge calls for the development of a new generation of systems for intelligent exploration of these models. Here, we introduce a novel paradigm for the exploration of digital body models illustrating cerebral vasculature. It enables dynamic scene compositing, real‐time interaction combined with animation, correlation of 3D models with sectional images, quantification as well as 3D manipulation‐independent labeling and knowledge‐related meta labeling (with name, diameter, description, variants, and references). This novel exploration is incorporated into a 3D atlas of cerebral vasculature with arteries and veins along with the surrounding surface and sectional neuroanatomy derived from 3.0 Tesla scans. This exploration paradigm is useful in medical education, training, research, and clinical applications. It enables development of new generation systems for rapid and intelligent exploration of complicated digital body models in real time with dynamic scene compositing from highly parcellated 3D models, continuous navigation, and manipulation‐independent labeling with multiple features.

Design and development of a new facility for teaching and research in clinical anatomy
Authors: Greene John Richard T. 
Published: February 2009

AbstractThis article discusses factors in the design, commissioning, project management, and intellectual property protection of developments within a new clinical anatomy facility in the United Kingdom. The project was aimed at creating cost‐effective facilities that would address widespread concerns over anatomy teaching, and support other activities central to the university mission–namely research and community interaction. The new facilities comprise an engaging learning environment and were designed to support a range of pedagogies appropriate to the needs of healthcare professionals at different stages of their careers. Specific innovations include integrated workstations each comprising of a dissection table, with removable top sections, an overhead operating light, and ceiling‐mounted camera. The tables incorporate waterproof touch‐screen monitors to display images from the camera, an endoscope or a database of images, videos, and tutorials. The screens work independently so that instructors can run different teaching sessions simultaneously and students can progress at different speeds to suit themselves. Further, database access is provided from within an integrated anatomy and pathology museum and display units dedicated to the correlation of cross‐sectional anatomy with medical imaging. A new functional neuroanatomy modeling system, called the BrainTower®, has been developed to aid integration of anatomy with physiology and clinical neurology. Many aspects of the new facility are reproduced within a Mobile Teaching Unit, which can be driven to hospitals, colleges, and schools to provide appropriate work‐based education and community interaction.

Impact of license choice on Open Source Software development activity
Authors: Colazo Jorge , Fang Yulin 
Published: February 2009

AbstractThe Open Source Software (OSS) development model has emerged as an important competing paradigm to proprietary alternatives; however, insufficient research exists to understand the influence of some OSS project characteristics on the level of activity of the development process. A basic such characteristic is the selection of the project's software license. Drawing upon social movement theory, our study examined the relationship between OSS licenses and project activity. Some OSS licenses include a “copyleft” clause, which requires that if derivative products are to be released, it must be done under the license the original product had. We hypothesize that copylefted licenses, as opposed to noncopylefted licenses, are associated with higher developer membership and coding activity, faster development speed, and longer developer permanence in the project. To test the hypotheses, we used archival data sources of working OSS projects spanning several years of development time. We discuss practical and theoretical implications of the results as well as future research ideas.
Insights into the relationship between the h‐index and self‐citations
Authors: Gianoli Ernesto , Molina‐Montenegro Marco A. 
Published: February 2009

AbstractWe analyze the publication output of 119 Chilean ecologists and find strong evidence that self‐citations significantly affect the h‐index increase. Furthermore, we show that the relationship between the increase in the h‐index and the proportion of self‐citations differs between high and low h‐index researchers. In particular, our results show that it is in the low h‐index group where self‐citations cause the greater impact.
Long‐term radio behaviour of GPS sources and candidates

Published: February 2009

AbstractThis paper is a summary of the work that our group has done (and recently published in several papers) on long‐term radio variability of GPS sources. We have studied the long‐term (up to 30 years) variability of GPS sources and candidates, with emphasis on the high‐frequency radio domain. Our data sets show that only a relatively small number of these sources retain their convex spectra when they are monitored densely and for long periods of time. The current GPS samples are especially contaminated by small, beamed blazar‐type sources. Also the remaining population with consistently convex GPS‐type spectra seems to be heterogeneous, falling into several subpopulations when their observed properties are used for clustering them through a self‐organizing map (© 2009 WILEY‐VCH Verlag GmbH & Co.

Parsec‐scale jet in the distant gigahertz‐peaked spectrum quasar PKS 0858–279
Authors: Kovalev Y. Y. 
Published: February 2009

AbstractThe high redshift GPS quasar PKS 0858–279 exhibits the following properties which make the source unusual. Our RATAN‐600 monitoring of 1–22 GHz spectrum has detected broad‐band radio variability with high amplitude and relatively short time scale. In the same time, the milliarcsecond scale structure observed in a snapshot VLBA survey turned out to be very resolved which is not expected from the fast flux density variations. We performed 1.4–22 GHz VLBA observations of this quasar in 2005–2007. It has revealed a core‐jet morphology. A high Doppler factor δ is suggested for the jet, its nature is discussed in this report on the basis of the multi‐frequency VLBA and RATAN data collected. Synchrotron self‐absorption was confirmed to be dominating at low frequencies, the magnetic field strength of the dominating jet feature is estimated of an order of 0.1δ mG (© 2009 WILEY‐VCH Verlag GmbH & Co.

The building blocks of young AGNs: A progress report on follow‐up projects with the CORALZ sample
Authors: Mack K.‐H. , Snellen I.A.G. , Schilizzi R.T. , Vries N. de 
Published: February 2009

AbstractThis paper summarizes some of the ongoing projects on the CORALZ sample, the first statistically complete sample of young radio galaxies. The low redshift of the sources in the sample (z < 0.16) makes them excellent targets for a comprehensive and homogeneous follow‐up in virtually all bands of the electromagnetic spectrum. Here we report on the almost completed radio continuum observations which confirm the relatively young ages of the sources in the CORALZ sample. The radio spectra in addition with new measurements at 250 GHz indicate a large fraction of sources with excess mm‐emission, probably due to radiation of cold dust. These sources are also excellent candidates for detection ofmolecular gas, which we have traced through CO observations in the 3‐mm band in several cases. Additional molecules as H2O or OH are being observed. The atomic gas content is disclosed by H I absorption observations (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Testing Homogeneity of Two Zero‐inflated Poisson Populations
Authors: Tse Siu Keung , Chow Shein Chung , Lu Qingshu , Cosmatos Dennis 
Published: February 2009

AbstractThe problem of testing treatment difference in the occurrence of a safety parameter in a randomized parallel‐group comparative clinical trial under the assumption that the number of occurrence follows a zero‐inflated Poisson (ZIP) distribution is considered. Likelihood ratio tests (LRT) for homogeneity of two ZIP populations are derived under the hypotheses that (i) there is no difference in inflation parameters, (ii) there is no difference in non‐zero means; and (iii) there is no difference in both inflation parameters and non‐zero means. Approximate formulas for sample size calculation are also obtained for achieving a desired power for detecting a clinically meaningful difference under the corresponding alternative hypotheses. An example concerning the assessment of the gastrointestinal (GI) safety in terms of the number of erosion counts of a newly developed compound for the treatment of osteoarthritis and rheumatoid arthritis is given for illustration purpose (© 2009 WILEY‐VCH Verlag GmbH & Co.

Published: February 2009

AbstractProgress in osmabenzene chemistry: The new stable osmabenzene phosphonium salts can be easily obtained from the reaction of [OsX2(PPh3)3] with HCCCH(OH)CCH, which constitutes a valuable addition to previous metallabenzene synthetic methodologies (see scheme). The redox behavior of several osmabenzenes with different co‐ligands has been investigated.magnified imageTreatment of [OsCl2(PPh3)3] with HCCCH(OH)CCH/PPh3 produces the osmabenzene [Os{CHC(PPh3)CHC(PPh3)CH}Cl2(PPh3)2][OH] (2), which is air stable in both solution and solid state. The key intermediate of the one‐pot reaction, [OsCl2{CHC(PPh3)CH(OH)CCH}(PPh3)2] (3), and the related complex [Os(NCS)2{CHC(PPh3)CH(OH)CCH}(PPh3)2] (7) have been isolated and characterized, further supporting the proposed mechanisms for the reaction. Reactions of 3 with PPh3, NaI, and NaSCN give osmabenzene 2, iodo‐substituted osmabenzene [Os{CHC(PPh3)CHCICH}I2(PPh3)2] (4), and thiocyanato‐substituted osmabenzene [Os{CHC(PPh3)CHC(SCN)CH}(NCS)2(PPh3)2] (5) respectively. Similarly, reaction of [OsBr2(PPh3)3] with HCCCH(OH)C CH in THF produces [OsBr2{CHC(PPh3)CH(OH)CCH}(PPh3)2] (9), which reacts with PPh3/Bu4NBr to give osmabenzene [Os{CHC(PPh3)CHC(PPh3)CH}Br2(PPh3)2]Br (10). Ligand substitution reactions of 2 produce a series of new stable osmabenzenes 11–17. An electrochemical study shows that osmabenzenes 2, 12, and 14–17 have interesting different electrochemical properties due to the different co‐ligand. The oxidation potentials of complexes 2, 12, 16, and 17 with Cl, NCS, and N(CN)2 ligands gradually positively shift in the sequence of Cl<NCS<N(CN)2. Among the six compounds, only 12 and 17 undergo a well‐behaved, nearly reversible and a quasi‐reversible reduction process, respectively, indicating that two NCS or N(CN)2 ligands contribute to the stabilization of their reduced states.
The Bis(pentafluoroethyl)phosphinous Acid (C2F5)2POH

Published: February 2009

AbstractPhosphinous acid or phosphane oxide? Both tautomers of (C2F5)2POH (see picture) are found in the neat liquid, whereas only phosphinous acid is present in the gas phase or in solution. The synthesis starting from (C2F5)3PF2, the thermodynamics of the tautomerization, and the detection and thermodynamics of the cis‐/trans‐POH rotamers of the acid are described.magnified imageThe industrial product (C2F5)3PF2 is transformed into the phosphinic acid chloride (C2F5)2P(O)Cl, which reacts with an excess of Bu3SnH in a clean, multistep reaction to give the stannyl derivative (C2F5)2POSnBu3. Subsequent treatment with gaseous HBr leads to the formation of (C2F5)2POH, which is isolated in 70 % yield. Besides (CF3)2POH, bis(pentafluoroethyl)phosphinous acid, (C2F5)2POH, represents the second known example of a phosphinous acid that is predicted by using density functional theory calculations at the B3PW91/6–311G(3d,p) level to be more stable than the phosphane oxide tautomer, the energy difference being 11.7 kJ mol−1. Only the phosphinous acid isomer is detectable in the gas phase and in solution. However, investigations of the neat liquid reveal a temperature‐dependent tautomeric equilibrium with the phosphane oxide isomer (C2F5)2P(O)H, which is characterized by vibrational and multinuclear NMR spectroscopic methods in combination with quantum‐chemical calculations.
Radical and Radical–Ionic Multicomponent Processes

Published: February 2009

AbstractAll in one pot! Radical, radical–ionic, and radical–organometallic MCR are highly convergent processes, representing a useful pathway to molecular and structural diversity (see scheme). This concept article highlights recent developments in the field and shows the potential of the strategy for the economical elaboration of various kinds of organic substrates.magnified imageProgress in multicomponent reactions (MCRs) based on ionic and organometallic processes has recently allowed the synthesis, with high efficiency, of large collections of drug‐like molecules. In contrast, MCRs based on cascade radical reactions appear to have attracted, so far, much less interest. This concept article highlights the latest progress in the field and underlines the potential of such an approach. The collected examples demonstrate that radical and radical–ionic MCRs are highly convergent processes leading to useful structural diversity.

AbstractMaking the right ligand selection: DFT calculations of Gibbs energies for the one‐electron photooxidation of guanine by six RuII–polypyridine complexes are reported. The theoretical predictions are compared with new EPR spectra. Our theoretical calculations confirm the experimental observations that the direct photooxidation of guanine by [Ru(bpz)3]2+, [Ru(tap)3]2+, and [Ru(bpz)2(dppz)]2+ is thermodynamically favorable, but is unfavorable with [Ru(bpy)3]2+, [Ru(phen)3]2+, and [Ru(bpy)2(dppz)]2+ (see figure).magnified image
