Authors: Khalsa Manjit K. , Greiner‐Ferris Julie M. , Hofmann Stefan G. , Khalsa Sat Bir S. 
Published: May 2014

Cognitive behavioural therapy (CBT) is an effective treatment for generalized anxiety disorder, but there is still room for improvement. The aim of the present study was to examine the potential benefit of enriching CBT with kundalini yoga (Y‐CBT). Participants consisted of treatment resistant clients at a community mental health clinic. A total of 32 participants enrolled in the study and 22 completed the programme. After the Y‐CBT intervention, pre‐post comparisons showed statistically significant improvements in state and trait anxiety, depression, panic, sleep and quality of life. Results from this preliminary study suggest that Y‐CBT may have potential as a promising treatment for those suffering from generalized anxiety disorder.

Implementing virtual platform for global‐scale cyber physical system networks
Authors: Ahn SungWon , Yoo Chuck , Lee ShinHyung , Lee HyungSoo , Kim Sung Jo 
Published: May 2014

SummaryThe need for global‐scale cyber physical system (CPS) is increasing with the evolution of CPS research. A global‐scale CPS requires additional considerations beyond the well‐known CPS requirements, such as security, reliability, and timely delivery, which cannot be easily satisfied when a CPS becomes global scale. Building an entire dedicated network for a global‐scale CPS cannot be a solution, because it requires a large capital outlay in order to be actualized. To overcome these obstacles, we implement a virtual platform named Xebra that includes effective CPS middleware for realizing a global‐scale CPS and isolation techniques based on virtualization. In this paper, we discuss the requirements for realizing global‐scale CPS network, and also, we introduce our implementation as a virtual platform with its performance evaluation.

Published: May 2014

SUMMARYA compact Cherenkov free‐electron laser operating in the terahertz spectral range is being developed. Analysis of the double‐slab type optical resonator has clarified the resonant frequency, the small signal gain, and the saturation power of the device. One‐dimensional simulation code predicted a small signal gain of 6% with a 50 kV/3.6 mA electron beam. The saturation power was estimated to be 90 mW. The out‐coupling structure of the resonator was designed using 3D simulation code. A transmittivity of 3.0% and a spread angle of 0.4 rad were predicted.

Published: May 2014

SUMMARYMultiwalled carbon nanotube (CNT)/epoxy nanocomposites were fabricated and used to coat epoxy insulating substrates in order to uniformize the surface conductivity. The effects of polymer functionalization of CNT on the dispersion of CNT in an epoxy matrix and on the electrical surface conductivity were investigated. It was found that grafting polymer molecules onto the CNT surface improved the dispersion of CNT in an epoxy matrix compared to those containing CNT without functionalization. The surface conductivity of nanocomposites decreases, thanks to uniform dispersion of CNT.

Published: May 2014

SUMMARYWe fabricated an ultrasonic probe with a through hole for needle puncture. The probe consists of a ring‐shaped transducer around the hole for detecting the needle tip and 12 fan‐shaped transducers around the ring‐shaped transducer for observing the lesion area. A B‐mode image was obtained for inserting a needle into pig liver. We investigated the phase of the signals from the needle tip using an ultrasonic probe having separated transmitter and receiver elements. From the experimental results the detection principle of the needle tip was explained by edge waves.
Alkenyl‐Alkynylgermanes Functionalised by Lewis Acids: Intramolecular Aluminium– and Gallium–Alkyne Interactions and Potential Ge–C Bond Activation
Authors: Uhl Werner , Pelties Stefan , Rohling Martina , Tannert Jens 
Published: May 2014

AbstractTreatment of various diethynylgermanes, (R1)2Ge(C≡C–R2)2 (R1 = C6H5, CH3; R1–R1 = C6H4–C6H4; R2 = CH3, CMe3, nBu, C6H5), with equimolar quantities of di(tert‐butyl)aluminium or ‐gallium hydride, R2E–H (E = Al, Ga), afforded mixed alkenyl‐alkynylgermanes, (R1)2Ge(C≡C–R2)[C{E(CMe3)2}=C(H)–R2], by reduction of one of their C≡C triple bonds. The alkenyl groups have a cis arrangement of H and Al or Ga atoms across the C=C double bonds, which reflects the kinetically favoured situation. The cis/trans isomerisation is probably prevented from yielding thermodynamically favoured trans isomers; this is a result of an intramolecular bonding interaction between the α‐carbon atoms of the remaining ethynyl groups and the coordinatively unsaturated metal atoms. The higher Lewis acidity of Al compared to Ga results in relatively short Al···C(ethynyl) contacts (>231.2 pm) and a concomitant lengthening of the Ge–C bonds.
Fluorinated Alkynylphosphonates in C,C‐Cyclizations: Regioselective Formation of Polysubstituted Fluorinated Arylphosphonates
Authors: Duda Blazej , Tverdomed Sergey N. , Ionin Boris I. , Röschenthaler Gerd‐Volker 
Published: May 2014

AbstractThe regioselective C,C‐cyclization of selected 1,4‐bipolar substrates with fluorinated alkynylphosphonates provided polysubstituted benzenes and naphthalenes in up to 98 % yield. For the case in which tetraethyl ethynylbisphosphonate was used, an unexpected phosphonate–phosphoramidate rearrangement was, for the first time, observed, which occurred in excellent yield.
A Cycloaddition–Cyclization Combined Approach to Enantiopure 3‐Glycinyl‐4‐hydroxypyrrolidines and 3‐Substituted 4‐Hydroxyprolines
Authors: Aouadi Kaïss , Abdoul‐Zabar Juliane , Msaddek Moncef , Praly Jean‐Pierre 
Published: May 2014

AbstractThe cycloaddition between (E)‐ or (Z)‐1,4‐dichloro‐2‐butene and a menthone‐derived nitrone as a glycine equivalent afforded dichlorinated isoxazolidine‐based cycloadducts. The stereochemistry of these adducts was controlled by the configuration of the starting alkene and nitrone. An amino group was generated either by reductive cleavage of the isoxazolidine N–O bond or by azidation and a subsequent reduction, which triggered in both routes a cyclization reaction that proceeded through a chloride displacement. This approach afforded unprecedented 3‐substituted 4‐hydroxyproline derivatives and (αS,3R,4S)‐3‐glycinyl‐4‐hydroxypyrrolidine. Both enantiomers of the reported products can be prepared by using one or the other nitrone enantiomer.
Changes in opioid and other analgesic use 1995–2010: Repeated cross‐sectional analysis of dispensed prescribing for a large geographical population inScotland
Authors: Ruscitto A. , Smith B.H. , Guthrie B. 
Published: May 2014

AbstractBackgroundDespite recent concerns about increasing rates of analgesic prescribing, detailed epidemiological studies are lacking. We identified and described changes in the pattern of community‐dispensed prescriptions to theTayside population,Scotland, between 31stMarch 1995 (n = 301,020) and 31stMarch 2010 (n = 311,881).MethodsRepeated cross‐sectional analysis of patient‐level population data on dispensed analgesics, stratified by sociodemographic variables; logistic regression to identify factors associated with strong opioid dispensing in 2010.ResultsThe proportion of people currently dispensed any analgesic increased in 2010 (17.9%) compared with 1995 (15.7%). This increase was not equal across drug classes, with paracetamol, opioids and gabapentin/pregabalin showing an increase, but others showing a decrease. Weak opioids were less commonly dispensed in 2010 (8.2% vs. 8.4%) but dispensing of strong opioids increased 18‐fold (3.6% vs. 0.2%), including a five‐fold increase of morphine, fentanyl or oxycodone (0.75% vs. 0.15%). People receiving more non‐analgesic drugs (odds ratio 20.7 if dispensed >14 non‐analgesic medications vs. those dispensed <4) and those living in more deprived areas (OR 1.63 most deprived vs. most affluent) were more likely to receive a strong opioid in 2010.ConclusionsAnalgesic use rose modestly between 1995 and 2010, but with larger changes within individual classes, only partly reflecting evidence‐based guidance. Dispensing of strong opioids increased dramatically, largely driven by tramadol, although other strong opioids tripled. Polypharmacy and socio‐economic deprivation were strongly associated with strong opioid use. Research is needed to establish the causes, benefits and harms of the increase in analgesic, and especially strong opioid use.
Connections between the discontinuous Galerkin method and high‐order flux reconstruction schemes
Authors: De Grazia D. , Mengaldo G. , Moxey D. , Vincent P. E. , Sherwin S. J. 
Published: May 2014

SUMMARYWith high‐order methods becoming more widely adopted throughout the field of computational fluid dynamics, the development of new computationally efficient algorithms has increased tremendously in recent years. One of the most recent methods to be developed is the flux reconstruction approach, which allows various well‐known high‐order schemes to be cast within a single unifying framework. Whilst a connection between flux reconstruction and the more widely adopted discontinuous Galerkin method has been established elsewhere, it still remains to fully investigate the explicit connections between the many popular variants of the discontinuous Galerkin method and the flux reconstruction approach. In this work, we closely examine the connections between three nodal versions of tensor‐product discontinuous Galerkin spectral element approximations and two types of flux reconstruction schemes for solving systems of conservation laws on quadrilateral meshes. The different types of discontinuous Galerkin approximations arise from the choice of the solution nodes of the Lagrange basis representing the solution and from the quadrature approximation used to integrate the mass matrix and the other terms of the discretization. By considering both linear and nonlinear advection equations on a regular grid, we examine the mathematical properties that connect these discretizations. These arguments are further confirmed by the results of an empirical numerical study. Copyright © 2014 John Wiley & Sons, Ltd.
Large scale problems arising from image registration
Authors: Fischer Bernd , Modersitzki Jan 
Published: May 2014

AbstractImage registration, in particular medical image registration, has been subject to extensive studies in the past years. Its versatile and important applications have attracted researchers from various branches, including numerical analysts. In this note, we not only give an overview on some new and exiting approaches but also point out some of the mathematical challenges associated with these approaches. Moreover, we explain why variational based methods to image registration naturally lead to large scaled and challenging optimization and hence numerical linear algebra problems. We present various instructive examples and comment on numerical schemes. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
