Authors: Sabata A. De , Matekovits L. 
Published: April 2012

AbstractA solution for mitigation of parallel‐plate noise in power distribution networks of high speed digital and mixed‐signal circuits and of printed circuit boards based on an inhomogeneous parallel‐plate waveguide (PPW) is proposed. The PPW consists of two different dielectric layers and a high impedance surface at their interface. The frequency related properties of the structure are studied through the numerically computed dispersion diagram. © 2012 Wiley Periodicals, Inc.

Authors: Mahdavi Mehdi , Atlasbaf Zahra , Forooraghi Keyvan 
Published: April 2012

AbstractA very compact printed circular monopole antenna for ultra‐wideband applications is presented. To achieve wide bandwidth performance, the proposed antenna is fed by a coplanar waveguide feedline. The total size of antenna is as small as 12 mm× 22 mm × 0.787 mm. The simulated and measured results demonstrate an impedance bandwidth covering 2.9–11.6 GHz for return loss less than −10 dB, which indicates that the proposed antenna performance is appropriate for UWB applications. © 2012 Wiley Periodicals, Inc.

High frame rate retrospectively triggered Cine MRI for assessment of murine diastolic function

Published: April 2012

AbstractTo assess left ventricular (LV) diastolic function in mice with Cine MRI, a high frame rate (>60 frames per cardiac cycle) is required. For conventional electrocardiography‐triggered Cine MRI, the frame rate is inversely proportional to the pulse repetition time (TR). However, TR cannot be lowered at will to increase the frame rate because of gradient hardware, spatial resolution, and signal‐to‐noise limitations. To overcome these limitations associated with electrocardiography‐triggered Cine MRI, in this paper, we introduce a retrospectively triggered Cine MRI protocol capable of producing high‐resolution high frame rate Cine MRI of the mouse heart for addressing left ventricular diastolic function. Simulations were performed to investigate the influence of MRI sequence parameters and the k‐space filling trajectory in relation to the desired number of frames per cardiac cycle. An optimized protocol was applied in vivo and compared with electrocardiography‐triggered Cine for which a high‐frame rate could only be achieved by several interleaved acquisitions. Retrospective high frame rate Cine MRI proved superior to the interleaved electrocardiography‐triggered protocols. High spatial‐resolution Cine movies with frames rates up to 80 frames per cardiac cycle were obtained in 25 min. Analysis of left ventricular filling rate curves allowed accurate determination of early and late filling rates and revealed subtle impairments in left ventricular diastolic function of diabetic mice in comparison with nondiabetic mice.

Authors: Collongues Nicolas , Casez Olivier , Lacour Arnaud , Tranchant Christine , Vermersch Patrick , de Seze Jérôme , Lebrun Christine 
Published: April 2012

AbstractIntroduction:Few data are available about the effect of rituximab (RTX) on refractory (RM) and non‐refractory (NRM) myasthenia.Methods:This retrospective multicenter study involved 13 RM and 7 NRM patients treated with sequential RTX infusions over 2 years, on average. RTX was used as a substitute for corticosteroids in NRM patients. Disability was assessed using the annualized relapse rate (ARR) and Myasthenia Gravis Foundation of America (MGFA) scores.Results:RTX induction decreased the ARR from 2.1 to 0.3 (P < 0.001), and lowered MGFA scores from 5–3b to 4b–0 in RM patients, and from 1.9 to 0.1 (P < 0.001) and 4b–2b to 3b–0 in NRM patients. No side effects were reported in either group, except for 1 case of spondylodiscitis 1 year after the last RTX infusion. Within a year after RTX induction, complete corticosteroid withdrawal was obtained in 7 RM and 4 NRM patients.Conclusions:RTX is efficacious and well‐tolerated. Its use allows for dose reduction or withdrawal of corticosteroids. Muscle Nerve, 2012

Published: April 2012

AbstractIntroduction:Spinal and bulbar muscular atrophy (SBMA) is an adult‐onset motor neuron disease caused by a CAG repeat expansion in the androgen receptor gene. The aim of this study was to verify whether urinary 8‐hydroxydeoxyguanosine (8‐OHdG), an oxidative stress marker, is a biomarker for SBMA.Methods:We measured the levels of urinary 8‐OHdG in 33 genetically confirmed SBMA patients and 32 age‐matched controls over a 24‐month period at 6‐month intervals.Results:Urinary 8‐OHdG levels in SBMA patients were significantly elevated compared with those of controls and correlated well with motor function scores. During the follow‐up period, urinary 8‐OHdG levels increased and correlated with motor function at each time‐point. In addition, urinary 8‐OHdG levels at baseline were correlated with changes in the 6‐minute walk test during 24 months.Conclusions:Urinary 8‐OHdG is a biomarker for SBMA, reflecting the severity and possibly predicting the deterioration of motor function.

Authors: Evliyaoglu Ferhat , Karadag Remzi , Burakgazi Ahmet Z. 
Published: April 2012

AbstractOcular movements and coordination require complex and integrated functions of somatic and autonomic nervous systems. Neurological disorders affecting these nervous systems may cause ocular dysfunction involving extraocular muscles and pupils. In this article, the prevalence, clinical presentations, and management of ocular neuropathy related to certain peripheral neuropathies, including diabetic neuropathy, Guillain–Barré syndrome (GBS), chronic inflammatory neuropathies, human immunodeficiency virus (HIV)‐associated neuropathy, and hereditary neuropathies, are examined in detail.

Mass spectrometry analysis reveals non‐mutated apolipoprotein a1 lumbosacral radiculoplexus amyloidoma
Authors: Loavenbruck Adam J. , Chaudhry Vinay , Zeldenrust Steven R. , Spinner Robert J. , Theis Jason D. , Klein Christopher J. 
Published: April 2012

AbstractIntroduction: In rare instances, amyloidosis presents as a focal, macroscopic lesion involving peripheral neural tissues (amyloidoma). In all known reported cases, peripheral nerve amyloidomas have had immunoglobulin light‐chain fibril composition and occurred in the context of paraproteinemia. Methods: A 46‐year‐old man presented with progressive insidious‐onset right lumbosacral radiculoplexus neuropathy without paraproteinemia. MRI‐targeted fascicular nerve biopsy was performed on an enlarged sciatic nerve after earlier distal fibular nerve biopsy was nondiagnostic. Laser dissected mass spectroscopy of the discovered amyloid protein was performed after immunohistochemistry failed to identify the specific amyloid protein. Complete gene sequencing of apolipoprotein A1 (ApoA1) was performed. Results: Only wild‐type ApoA1 amyloid was found in the congophilic component in the nerve. Conclusions: This case highlights the utility of MRI‐guided fascicular nerve biopsy combined with laser‐dissected mass spectrometric analysis. Importantly, the case expands the known causes of amyloidomas to include wild‐type ApoA1. Muscle Nerve 46: 817–822, 2012

Published: April 2012

AbstractIntroduction: The aim of this study was to evaluate the ultrasound (US) morphological changes of sural nerves (SNs) of uremic patients on hemodialysis. Methods: Sixty‐six SNs in 33 uremic patients were examined by 22‐MHZ high‐frequency US and routine nerve conduction studies (NCS), and 76 SNs in 38 controls were also examined. Cross‐sectional area (CSA) and maximal fascicular thickness (MFT) of the SNs were measured. Results: The inner parts of the SN were clearly identified in all participants. There were significant increases in CSA and MFT in the patient group (1.86 ± 0.53 mm2 and 0.37 ± 0.08 mm, respectively) compared with the control group (1.38 ± 0.25 mm2 and 0.32 ± 0.03 mm, respectively) (P < 0.001). Fifty‐seven SNs (86.36%) had abnormal CSAs, and 51 SNs (77.27%) had abnormal MFTs in the patient group, which was higher than NCS abnormalities (66.67%). Conclusions: A 22‐MHZ US can show morphological changes in the SNs of uremic patients and may be a valuable tool. Muscle Nerve, 2012
Nested column generation applied to the crude oil tanker routing and scheduling problem with split pickup and split delivery
Authors: Hennig Frank , Nygreen Bjørn , Lübbecke Marco E. 
Published: April 2012

AbstractThe split pickup split delivery crude oil tanker routing and scheduling problem is a difficult combinatorial optimization problem, both theoretically and practically. However, because of the large expenses in crude oil shipping it is attractive to make use of optimization that exploits as many degrees of freedom as possible to save transportation cost. We propose a nested column generation algorithm for this particular split pickup split delivery problem which bears several complexities such as a heterogeneous fleet, multiple commodities, many‐to‐many relations for pickup and delivery of each commodity, sequence dependent vehicle capacities, and cargo quantity dependent pickup and delivery times. Our approach builds on a branch‐and‐price algorithm in which the column generation subproblems are solved by branch‐and‐price themselves. We describe our implementation in the branch‐cut‐and‐price framework SCIP and give computational results for realistic test instances. The high quality schedules we obtain for these instances improve on those in previous studies. © 2012 Wiley Periodicals, Inc. Naval Research Logistics, 2012
Characterization of the homodimerization interface and functional hotspots of the CXCR4 chemokine receptor
Authors: Rodríguez David , Gutiérrez‐de‐Terán Hugo 
Published: April 2012

AbstractThe recent crystallographic structures of the human chemokine CXC Receptor 4 (CXCR4) provide experimental evidence of a human G Protein‐Coupled Receptor (GPCR) dimer in atomic detail. The CXCR4 homodimers reveal an unexpected dimerization mode involving transmembrane helices TM5 and TM6, which is examined here using all‐atom molecular dynamics (MD) simulations in the physiological environment of a lipid bilayer. The bacteriophage T4 lysozyme (T4L), which was fused to the crystallized protein but absent in our simulations, is found to slightly affect the observed relative position of the protomers in the two dimers studied here, and consequently some rearrangements of the dimerization interface are proposed. In addition, the simulations provide further evidence about the role of the two stabilizing single point mutations introduced to crystallize the receptor. Finally, this work analyzes the structural and dynamic role of key residues involved both in ligand binding and in the infection process of HIV. In particular, the different side chain conformations of His1133.39 are found to influence the dynamics of the surrounding functional hotspot region being evaluated both in the presence and in the absence of the co‐crystallized ligand IT1t. The analysis reported here adds valuable knowledge for future structure‐based drug design (SBDD) efforts on this pharmacological target. Proteins 2012;. © 2012 Wiley Periodicals, Inc.

Authors: Wang Yanhua , Chen Liping , Yu Ruixian , Zhao Xueping , Wu Changxing , Cang Tao , Wang Qiang 
Published: April 2012

AbstractBACKGROUND: The parasitoid Trichogramma ostriniae (Pang and Chen) is a major natural enemy of many lepidopterans, but only a few studies have been conducted on the compatibility of biological and chemical controls. In this study, the selectivity of 30 insecticides to T. ostriniae adults was evaluated.RESULTS: Among the seven classes of chemicals tested, organophosphates and carbamates had the highest intrinsic toxicity to the wasp, with LC50 values ranging from 0.032 (0.029–0.038) to 2.38 (1.91–3.15) mg AI L−1. They are followed by phenylpyrazoles, avermectins, neonicotinoids and pyrethroids, which induce variable toxicity responses, with LC50 values ranging from 0.14 (0.11–0.21) to 56.67 (48.94–67.24) mg AI L−1, from 2.57 (1.85–4.28) to 4.48 (3.34–6.83) mg AI L−1, from 2.48 (1.80–4.03) to 503.6 (457.6–557.5) mg AI L−1 and from 5.44 (3.95–8.84) to 104.2 (92.48–119.7) mg AI L−1 respectively. The insect growth regulators (IGRs) exhibited least toxicity to the parasitoid.CONCLUSION: Risk quotient analysis classifies neonicotinoids, avermectins, pyrethroids, IGRs and phenylpyrazoles (with the exception of butane‐fipronil and fipronil) as safe agents to the parasitoid, but categorises organophosphates and carbamates as slightly to moderately toxic or dangerous to T. ostriniae.

Pair natural orbitals in explicitly correlated second‐order møller–plesset theory
Authors: Tew David P. , Hättig Christof 
Published: April 2012

AbstractAn improved formulation of pair natural orbital (PNO)–based explicitly correlated Møller–Plesset second‐order perturbation theory is presented. Increased efficiency has been achieved by modifying the representation of the strong orthogonality projector used in the evaluation of the F12 intermediates. We demonstrate two simple relationships between the truncation errors arising from PNOs in the virtual space and those arising from the PNOs in the strong orthogonality operators. This permits robust error control through a single parameter.
Statistical physics of a mesoscopic fermion system inside a rectangular box
Authors: Lungu Radu P. 
Published: April 2012

AbstractAn ideal Fermi gas of identical particles confined inside a rectangular box is considered. Using the grand‐canonical formalism and performing the summations over the one‐particle states numerically, the temperature dependence of the chemical potential, of the average energy and of the heat capacity are derived before the thermodynamic limit is taken. These mesoscopic quantities differ from the corresponding thermodynamic quantities only quantitatively but are qualitatively similar. © 2013 Wiley Periodicals, Inc.
TDDFT study on quantization behaviors of nonadiabatic couplings in polyatomic systems
Authors: Hu Chunping , Komakura Ryo , Li Zhengcao , Watanabe Kazuyuki 
Published: April 2012

AbstractWe present extensive calculations on the quantization behaviors of first‐order nonadiabatic couplings (NAC) in polyatomic systems, using the method based on time‐dependent density functional theory (TDDFT). Along circular contours around Jahn–Teller conical intersections at various symmetries, such as D4h and D6h, the angular NAC are found to show apparent dependence on the contour angle, no matter how close the conical intersections are approached. This is in contrast to that the angular NAC in triatomic Jahn–Teller systems (D3h) converge to the quantized value of 1/2. The oscillatory feature of our calculated curves qualitatively resembles the analytic result of angular NAC around elliptic conical intersections in the small‐displacement limit. Furthermore, by performing the integral along the whole contour, the quantization rule on the integral of the angular NAC holds for all cases, which gives the geometric phase with a value of π. On the other hand, the angular NAC in the immediate vicinity of Renner–Teller intersections are shown to be always 1. This observation can be understood from the fact that the molecular symmetry property of the Renner–Teller intersections is always determined by the linear atomic chain. Further analysis of our results on Renner–Teller systems shows that although the quantization behavior of angular NAC can determine all NAC vectors on each atom for the triatomic systems, it cannot for the systems with more than three atoms. The NAC vectors of the latter systems are found to show both common and distinct features with respect to the atomic number and species by our TDDFT calculations. © 2012 Wiley Periodicals, Inc.
Growth mode of CNFs on substrates by using the sputtering method
Authors: Hirase Yuji , Ichikawa Yo 
Published: April 2012

AbstractCarbon nanoflakes (CNFs) were grown on Si substrates at different substrate temperatures by radio frequency magnetron sputtering. The changes in the shape of CNFs caused by the substrate temperature and the places of CNF growth in the substrate were investigated. The adhesion of carbon materials to the substrate and the growth of crystallized flake‐like structures were found to be dependent on the substrate temperature. At a substrate temperature lower than 550 °C, no material was deposited on the substrate. At a substrate temperature higher than 600 °C, flake‐like carbon microstructures were grown. Therefore, only when the substrate temperature is higher than the crystallization temperature, the adhesion of carbon materials takes place and the CNF grows two dimensionally. In addition, it is suspected that CNF grows selectively in the direction of the greatest supply of sputtered particles. This selective growth is an intrinsic growth mode in the bipolar sputtering method. © 2012 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
Basic solution of four 3‐D rectangular limited‐permeable cracks in piezoelectric materials
Authors: Liu J.‐Y. , Zhou Z.‐G. , Zhou B.‐B. 
Published: April 2012

AbstractThe solution of four 3‐D rectangular limited‐permeable cracks in piezoelectric materials were given by using the generalized Almansi's theorem and the Schmidt method. At the same time, the electric permittivity of the air inside the rectangular crack was considered. The problem was formulated through Fourier transform as three pairs of dual integral equations, in which the unknown variables are the displacement jumps across the crack surfaces. To solve the dual integral equations, the displacement jumps across the crack surfaces were directly expanded as a series of Jacobi polynomials. Finally, the effects of the electric permittivity of the air inside the rectangular crack, the shape of the rectangular crack and the distance among four rectangular cracks on the stress and electric displacement intensity factors in piezoelectric materials were analyzed.

Published: April 2012

AbstractThe status of genomics and genetics research in the Myrtaceae, a large family of dicotyledonous woody plants, is reviewed withEucalyptusas the focal genus. The family contains over 5,650 species in 130 to 150 genera, predominantly of neo-tropical and Southern Hemisphere distribution. Several genera are well known for their economic importance worldwide. Myrtaceae are typically diploids with small to intermediate genome size. Microsatellites have been developed for several genera while higher throughput marker systems such as diversity arrays technology and single nucleotide polymorphism are available forEucalyptus. Molecular data have been fundamental to current perspectives on the phylogeny, phylogeography and taxonomy of the Myrtaceae, while numerous studies of genetic diversity have been carried out particularly as it relates to endangered, rare, fragmented, overharvested or economically important species. Large expressed sequence tag collections for species ofEucalyptushave recently become public to support the annotation of theEucalyptus grandisgenome. Transcriptomics inEucalyptushas advanced by microarrays and next-generation sequencing focusing on wood development. Linkage maps forEucalyptusdisplay high synteny across species and have been extensively used to map quantitative trait loci for a number of traits including growth, wood quality, disease and insect resistance. Candidate gene-based association genetics have successfully found marker–trait associations for wood and fiber traits. Genomic selection experiments have demonstrated clear potential to improve the efficiency of breeding programs while freeze-tolerant transgenicEucalyptustrials have recently been initiated. The recently releasedE. grandisgenome, sequenced to an average coverage of 8×, will open up exceptional opportunities to advance Myrtaceae genetics and genomics research.
