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

AbstractA 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

AbstractThis 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

AbstractField‐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

AbstractScheduling 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.
Reliability in grid computing systems
Authors: Dabrowski Christopher 
Published: February 2009

AbstractIn recent years, grid technology has emerged as an important tool for solving compute‐intensive problems within the scientific community and in industry. To further the development and adoption of this technology, researchers and practitioners from different disciplines have collaborated to produce standard specifications for implementing large‐scale, interoperable grid systems. The focus of this activity has been the Open Grid Forum, but other standards development organizations have also produced specifications that are used in grid systems. To date, these specifications have provided the basis for a growing number of operational grid systems used in scientific and industrial applications. However, if the growth of grid technology is to continue, it will be important that grid systems also provide high reliability. In particular, it will be critical to ensure that grid systems are reliable as they continue to grow in scale, exhibit greater dynamism, and become more heterogeneous in composition. Ensuring grid system reliability in turn requires that the specifications used to build these systems fully support reliable grid services. This study surveys work on grid reliability that has been done in recent years and reviews progress made toward achieving these goals. The survey identifies important issues and problems that researchers are working to overcome in order to develop reliability methods for large‐scale, heterogeneous, dynamic environments. The survey also illuminates reliability issues relating to standard specifications used in grid systems, identifying existing specifications that may need to be evolved and areas where new specifications are needed to better support the reliability.

A survey and review of the current state of rollback‐recovery for cluster systems
Authors: Maloney Andrew , Goscinski Andrzej 
Published: February 2009

AbstractA variety of research problems exist that require considerable time and computational resources to solve. Attempting to solve these problems produces long‐running applications that require a reliable and trustworthy system upon which they can be executed. Cluster systems provide an excellent environment upon which to run these applications because of their low cost to performance ratio; however, due to being created using commodity components they are prone to failures. This report surveyed and reviewed the issues currently relating to providing fault tolerance for long‐running applications. Several fault tolerance approaches were investigated; however, it was found that rollback‐recovery provides a favourable approach for user applications in cluster systems. Two facilities are required to provide fault tolerance using rollback‐recovery: checkpointing and recovery. It was shown here that a multitude of work has been done for enhancing checkpointing; however, the intricacies of providing recovery have been neglected. The problems associated with providing recovery include; providing transparent and autonomic recovery, selecting appropriate recovery computers, and maintaining a consistent observable behaviour when an application fails.

Resonance‐Enhanced Multiphoton Ionisation of Purine
Authors: Schneider Michael , Hain Tilman , Fischer Ingo 
Published: February 2009

AbstractState‐of‐the‐art molecular‐beam techniques reveal that the lowest lying electronic excited state in purine is the nπ* state. Using multiphoton ionization spectroscopy, the origin is found to occur at 31 309 cm−1, and a vibrational structure is visible that is assigned to the skeletal motion of the ring (see figure).magnified image
Self‐Assembly of Alkoxy‐Substituted Bis(hydrazone)‐Based Organic Ligands and of a Metallosupramolecular Grid on Graphite

Published: February 2009

AbstractOn edge: Self‐assembled monolayers of a bis(hydrazone)‐based molecular grid physisorbed on graphite are studied by scanning tunneling microscopy (see picture). High order is attained at the supramolecular level by thermal annealing of the grid‐based films. A preferential edge‐on configuration of the molecular grid with respect to the substrate is found.magnified imageSelf‐assembly of a bis(hydrazone) chelating ligand functionalized with octadecyloxy substituents is described, as well as the reproducible thermally activated self‐assembly of its metallosupramolecular cationic CoII [2×2] grid‐type complex, on a highly oriented pyrolitic graphite (HOPG) substrate. Scanning tunnelling microscopy measurements at the solid/liquid interface reveal that the grid units of the annealed films are oriented edge‐on to the basal plane of the HOPG, which indicates that the influence of the octadecyl chains is not sufficient to tie the grids into a face‐on orientation. To gain a detailed understanding of the self‐assembly behaviour of the grid on HOPG, the results for the grid itself have been compared to those of its constituent ligands.
Photolysis of 1‐C4H9I and 2‐C4H9I at 266 nm: Direct Observation of the Effect of Branching on the Photodissociation Mechanism
Authors: Liu Yuzhu , Zheng Qiusha , Zhang Yan , Zhang Rongrong , Wang Yanmei , Zhang Bing 
Published: February 2009

AbstractVelocity ion imaging (see figure) is used to analyze the photodissociation mechanism of 1‐C4H9I (left image) and 2‐C4H9I (right image) at 266 nm. For 2‐C4H9I, a new channel for formation of I and I* atoms is observed. It is attributed to the repulsive mode along the CI stretch, coupled with some bending motions.magnified imagePhotodissociation dynamics of 1‐C4H9I and 2‐C4H9I at 266 nm is investigated by velocity ion imaging. Photodissociation channels of 1‐C4H9I and 2‐C4H9I are analyzed and compared. For 1‐C4H9I the photodissociation dynamics only correlates with direct dissociation via repulsive surfaces. While for 2‐C4H9I, a new formation channel of I and I* atoms is observed. It is attributed to the repulsive mode along the CI stretch, coupled with some bending motions. As the alkyl group becomes more branched, the contribution of bending modes to I and I* is much more obvious in the photodissociation of 2‐C4H9I than in that of 1‐C4H9I. Additionally, the curve‐crossing probability between 3Q0 and 1Q1 increases greatly with branching, from 0.31 for 1‐C4H9I to 0.70 for 2‐C4H9I in the prompt dissociation channel; the relative quantum yield for I* decreases strongly with branching, from 0.65 for 1‐C4H9I to 0.28 for 2‐C4H9I.
The significance of endocervical cells and metaplastic squamous cells in liquid‐based cervical cytology
Authors: Leung Kai M. , Lam Manbo , Lee Joyce W. Y. , Yeoh Gary P. S. , Chan Keeng W. 
Published: February 2009

AbstractWe conducted a retrospective study to investigate whether the presence or absence of endocervical cells (EC) and metaplastic squamous cells (MSC) was associated with the detection of squamous intraepithelial lesions in liquid‐based cervical cytology. 90,376 cases of liquid‐based cervical cytology smears received in 2006 were included in the study. Low‐grade (LSIL) and high‐grade squamous intraepithelial lesions (HSIL) were classified according to the Bethesda system (2001). The rates of detecting LSIL and HSIL in smears with and without EC and/or MSC were determined. There were 1,540 LSIL and 396 HSIL. The ratio of HSIL/NILM (no intraepithelial lesion or malignancy) was 0.0022 in smears without EC or MSC, 0.0040 in smears with EC only, 0.0044 in smears with MSC only, and 0.0056 in smears with both EC and MSC present. Compared with smears without EC or MSC, this ratio was significantly higher (P < 0.05) when either EC or MSC was present. Compared with smears with EC only, the ratio was also significantly higher when both EC and MSC were present (P < 0.05). On the other hand, the presence or absence of EC had no effect on the detection rate of LSIL (0.0191 for both groups), while the presence of MSC was actually associated with lower detection rate of LSIL (0.0153, P < 0.05). The presence of endocervical and metaplastic cells was associated with higher detection rates of HSIL. MSC was associated with lower detection or LSIL. Diagn. Cytopathol. 2009. © 2009 Wiley‐Liss, Inc.
