Evolution of radio galaxies
Authors: Kaiser C.R.
Published: February 2009

The dynamical evolution of FRII‐type radio galaxies can be successfully modelled employing purely analytical techniques. The solutions change depending on the lobe size relative to the characteristic length scale for individual objects, resulting in three distinct regimes. By far the best understood regime is that of large sources. For these we can also construct emission models predicting the evolution of the radio luminosity as a function of source size or age and a limited number of source parameters. We can use such models to constrain the evolution of the radio galaxy population as a whole. Building on these successes, we find some hints that radio galaxies can change their morphologies between the two FR classes. Better emission models for all length scales and models for FRI‐type objects are now needed to progress our understanding of all evolutionary branches of radio galaxies (© 2009 WILEY‐VCH Verlag GmbH & Co.

Modelling the broad‐band spectra of X‐ray emitting GPS galaxies

Published: February 2009

The study of the broad‐band emission of GHz‐Peaked‐Spectrum (GPS) radio galaxies is a powerful tool to investigate the physical processes taking place in the central, kpc‐sized region of their active hosts, where the jets propagate and the lobes expand, interacting with the surrounding interstellar medium (ISM). We recently developed a new dynamical‐radiative model to describe the evolution of the GPS phenomenon (Stawarz et al. 2008): as the relativistic jets propagate through the ISM, gradually engulfing narrow‐line emitting gas clouds along their way, the electron population of the expanding lobes evolves, emitting synchrotron light, as well as inverse‐Compton radiation via up‐scattering of the photon fields from the host galaxy and its active nucleus. The model, which successfully reproduces the key features of the GPS radio sources as a class, provides a description of the evolution of their spectral energy distribution (SED) with the lobes' expansion, predicting significant and complex X‐ray to γ ‐ray emission.We apply here the model to the broad‐band SED's of a sample of known, X‐ray emitting GPS galaxies, and show that (i) the free‐free absorption mechanism enables us to reproduce the radio continuum at frequencies below the turnover; (ii) the lobes' non‐thermal, inverse‐Compton emission can account for the observed X‐ray spectra, providing a viable alternative to the thermal, accretion‐dominated scenario. We also show that, in our sample, the relationship between the X‐ray and radio hydrogen column densities, NH and NHI, is suggestive of a positive correlation, which, if confirmed, would support the scenario of high‐energy emitting lobes (© 2009 WILEY‐VCH Verlag GmbH & Co.

Interaction of radio jets with clouds in the ambient medium: Numerical simulations
Authors: Jeyakumar S.
Published: February 2009

Hydrodynamical simulations of jets interacting with clouds moving in the ambient medium of the host galaxy are presented. Clouds with sizes of the order of the jet diameter and smaller, crossing the path of the jet with different speeds are considered. In the case of slow moving clouds the jet is stopped over the brief period of time taken by the cloud to cross the jet. The jet maintains its general morphology in the case of fast moving clouds. Erosion of the clouds leads to redistribution of cloud material to large distances. Such interaction may explain the large outflow velocities observed from pc to kpc scales in the compact radio sources (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
RubAre symmetric radio spectra of some GPS/HFP sources related to a statistical acceleration mechanism?rik
Authors: Maselli A. , Massaro E.
Published: February 2009

We present the results of a new spectral analysis of a sample of HFPs. We took from literature simultaneous radio measurements at various epochs and studied the symmetry of flux distribution around the peak frequency by means of a logparabolic fit.We found that a large fraction of spectra are symmetric and propose that this property may be a consequence of statistical acceleration (© 2009 WILEY‐VCH Verlag GmbH & Co.

Exact, Distribution Free Confidence Intervals for Late Effects in Censored Matched Pairs
Authors: Daniel Shoshana R.
Published: February 2009

When comparing censored survival times for matched treated and control subjects, a late effect on survival is one that does not begin to appear until some time has passed. In a study of provider specialty in the treatment of ovarian cancer, a late divergence in the Kaplan–Meier survival curves hinted at superior survival among patients of gynecological oncologists, who employ chemotherapy less intensively, when compared to patients of medical oncologists, who employ chemotherapy more intensively; we ask whether this late divergence should be taken seriously. Specifically, we develop exact, permutation tests, and exact confidence intervals formed by inverting the tests, for late effects in matched pairs subject to random but heterogeneous censoring. Unlike other exact confidence intervals with censored data, the proposed intervals do not require knowledge of censoring times for patients who die. Exact distributions are consequences of two results about signs, signed ranks, and their conditional independence properties. One test, the late effects sign test, has the binomial distribution; the other, the late effects signed rank test, uses nonstandard ranks but nonetheless has the same exact distribution as Wilcoxon's signed rank test. A simulation shows that the late effects signed rank test has substantially more power to detect late effects than do conventional tests. The confidence statement provides information about both the timing and magnitude of late effects (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Evaluating Co‐primary Endpoints Collectively in Clinical Trials
Authors: Li Qian H.
Published: February 2009

Often a treatment is assessed by co‐primary endpoints so that a comprehensive picture of the treatment effect can be obtained. Co‐primary endpoints can be different medical assessments angled at different aspects of a disease, therefore, are used collectively to strengthen evidence for the treatment effect. It is common sense that if a treatment is ineffective, the chance to show that the treatment is effective in all co‐primary endpoints should be small. Therefore, it may not be necessary to require all the co‐primary endpoints to be statistically significant at the 1‐sided 0.025 level to control the error rate of wrongly approving an ineffective treatment. Rather it is reasonable to allow certain variation for the p ‐values within a range close to 0.025. In this paper, statistical methods are developed to derive decision rules to evaluate co‐primary endpoints collectively. The decision rules control the error rate of wrongly accepting an ineffective treatment at the level of 0.025 for a study and the error rate at a slightly higher level for a treatment that works for all the co‐primary endpoints except perhaps one. The decision rules also control the error rates for individual endpoints. Potential applications in clinical trials are presented (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Finite Mixture Models for Mapping Spatially Dependent Disease Counts
Authors: Alfó Marco , Nieddu Luciano , Vicari Donatella
Published: February 2009

A vast literature has recently been concerned with the analysis of variation in disease counts recorded across geographical areas with the aim of detecting clusters of regions with homogeneous behavior. Most of the proposed modeling approaches have been discussed for the univariate case and only very recently spatial models have been extended to predict more than one outcome simultaneously. In this paper we extend the standard finite mixture models to the analysis of multiple, spatially correlated, counts. Dependence among outcomes is modeled using a set of correlated random effects and estimation is carried out by numerical integration through an EM algorithm without assuming any specific parametric distribution for the random effects. The spatial structure is captured by the use of a Gibbs representation for the prior probabilities of component membership through a Strauss‐like model. The proposed model is illustrated using real data (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Pyrenylmethyldeoxyadenosine: A 3′‐Cap for Universal DNA Hybridization Probes
Authors: Printz Michael , Richert Clemens
Published: February 2009

Effect of a PAH on base pairing: A polycyclic aromatic hydrocarbon (PAH) covalently linked to the N6‐position of a dangling deoxyadenosine residue (see scheme) of an oligonucleotide increases target affinity, but decreases base‐pairing selectivity. Melting point increases of up to 28 °C (14 °C per residue) were observed, and 20 out of 24 mismatch‐containing duplexes are stabilized more strongly by the PAH substituent than their perfectly matched counterpart.

A ligand that stabilizes a three‐dimensional structure can be expected to have a positive effect on the specificity with which this structure is formed. Here we report on a ligand covalently linked to an oligonucleotide that increases duplex stability, but decreases base‐pairing selectivity at the terminus. The ligand consists of a dangling 2′‐deoxyadenosine residue with a pyrenylmethyl substituent at the N6‐position, that is, a deoxynucleoside with a covalently linked polycyclic aromatic hydrocarbon (PAH). In the presence of the pyrene‐bearing nucleosides the UV melting point (ΔTm) of duplexes increases by up to 29.1 °C. The modified residue lowers the base‐pairing fidelity at the terminal and penultimate position of duplexes with a depression in ΔΔTm observable in 20 out of 24 sequence contexts tested. The effect can be rationalized based on a modeled three‐dimensional structure. The results are significant for the understanding of base‐pairing fidelity in DNA duplexes as modulated by the presence of a polycyclic aromatic hydrocarbon. The fidelity‐decreasing effect may be useful for universal hybridization probes that bind to a broader range of sequences than conventional oligonucleotides.

A linear magnetic field scan driver
Authors: Quine Richard W. , Czechowski Tomasz , Eaton Gareth R.
Published: February 2009

A linear magnetic field scan driver was developed to provide a rapidly scanning magnetic field for use in electron paramagnetic resonance (EPR) spectroscopy. The driver consists of two parts: a digitally synthesized ramp waveform generator and a power amplifier to drive the magnetic field coils. Additionally, the driver provides a trigger signal to a data collection digitizer that is synchronized to the ramp waveform. The driver can also drive an arbitrary current waveform supplied from an external source. The waveform generator is computer controlled through a serial data interface. Additional functions are controlled by the user from the driver front panel. The frequency and amplitude of the waveform are each separately controlled with 12‐bit resolution (one part in 4,096). Several versions of the driver have been built with different frequency and amplitude ranges. Frequencies range from 500 to 20,000 Hz. Field sweep amplitudes range up to 80 Gpp. This article also gives a brief description of the field coils that are driven by the driver. © 2009 Wiley Periodicals, Inc.

Silicon cylinder spiral coil for nuclear magnetic resonance spectroscopy of nanoliter samples
Authors: Leidich Stefan , Braun Marco , Gessner Thomas , Riemer Thomas
Published: February 2009

This contribution presents a new high sensitivity microdetector designed for high resolution proton NMR at 750 MHz (17.6 T) of sample volumes ranging from 5 to 40 nl. The desired volume of fluid is placed in a sealed 330/200 μm outer/inner diameter glass capillary and is then situated in the center of the detection coil. The high quality factor detection coils are fabricated using silicon microtechnology. The materials from which the device is constructed are specially shaped to improve the homogeneity of the static magnetic field within the sample. Adverse effects of the finite, nonspherical sample geometry on the spectral resolution are mitigated by employing sample rotation up to 2.5 kHz at the magic angle. The new detector exhibits linewidths of smaller than 3.0 Hz (0.004 ppm) and a signal‐to‐noise ratio in the spectral domain of higher than 4,000 per μmol of water. Results with respect to sensitivity, spectral resolution, and total sample volume are given and put into context with already published microprobes. © 2009 Wiley Periodicals, Inc.

Design and construction of a prototype high‐power B0 insert coil for field‐cycled imaging in superconducting MRI systems
Authors: Alford Jamu K. , Scholl Timothy J. , Handler William B. , Chronik Blaine A.
Published: February 2009

Field‐cycled MRI provides a noninvasive quantification of the concentration of bound (activated) targeted contrast agents. For field‐cycled imaging to be performed within a clinical full‐body superconducting MRI magnet, an auxiliary insertable magnet is required that can dynamically change the main field strength during the MR pulse sequence. Herein, the design and construction of a solenoidal insert coil is discussed. Design aspects including active shielding, thermal performance, forces, and ramping times are examined. Proper materials, construction methods, and interfacing for the insert coil with a clinical MRI are also covered. Finally, a field‐cycled experiment in a 1.5 T clinical MRI system is described, demonstrating the feasibility of this method and then future novel contrasts available with field‐cycled MRI. © 2009 Wiley Periodicals, Inc.

Applying semantics to grid middleware
Authors: Vidal A. C. T. , Silva F. J. S. , Kofuji S. T. , Kon F.
Published: February 2009

Scheduling parallel and distributed applications efficiently onto grid environments is a difficult task and a great variety of scheduling heuristics has been developed aiming to address this issue. A successful grid resource allocation depends, among other things, on the quality of the available information about software artifacts and grid resources. In this article, we propose a semantic approach to integrate selection of equivalent resources and selection of equivalent software artifacts to improve the scheduling of resources suitable for a given set of application execution requirements. We also describe a prototype implementation of our approach based on the Integrade grid middleware and experimental results that illustrate its benefits. Copyright © 2009 John Wiley & Sons, Ltd.
