Published: June 2015

Duchenne muscular dystrophy (DMD) is caused by absence of the integral structural protein, dystrophin, which renders muscle fibres susceptible to injury and degeneration. This ultimately results in cardiorespiratory dysfunction, which is the predominant cause of death in DMD patients and highlights the importance of therapeutic targeting of the cardiorespiratory system. While there is some evidence to suggest that restoring dystrophin in the diaphragm improves both respiratory and cardiac function, the role of the diaphragm is not well understood. Here using exon skipping oligonucleotides we predominantly restored dystrophin in the diaphragm and assessed cardiac function by MRI. This approach reduced diaphragmatic pathophysiology and markedly improved diaphragm function but did not improve cardiac function or pathophysiology, with or without exercise. Interestingly, exercise resulted in a reduction of dystrophin protein and exon skipping in the diaphragm. This suggests that treatment regimens may require modification in more active patients. In conclusion, whilst the diaphragm is an important respiratory muscle, it is likely that dystrophin needs to be restored in other tissues, including multiple accessory respiratory muscles and of course the heart itself for appropriate therapeutic outcomes. This supports the requirement of a body-wide therapy to treat DMD.

Published: June 2015

The determination of the crustal structure is essential in geophysics, as it gives insight into the geohistory, tectonic environment, geohazard mitigation, etc. Here we present the latest advance on three-dimensional modeling representing the Tibetan Mohorovičić discontinuity (topography and ranges) and its deformation (fold), revealed by analyzing gravity data from GOCE mission. Our study shows noticeable advances in estimated Tibetan Moho model which is superior to the results using the earlier gravity models prior to GOCE. The higher quality gravity field of GOCE is reflected in the Moho solution: we find that the Moho is deeper than 65 km, which is twice the normal continental crust beneath most of the Qinghai-Tibetan plateau, while the deepest Moho, up to 82 km, is located in western Tibet. The amplitude of the Moho fold is estimated to be ranging from −9 km to 9 km with a standard deviation of ~2 km. The improved GOCE gravity derived Moho signals reveal a clear directionality of the Moho ranges and Moho fold structure, orthogonal to deformation rates observed by GPS. This geophysical feature, clearly more evident than the ones estimated using earlier gravity models, reveals that it is the result of the large compressional tectonic process.

Published: June 2015

Spinal muscular atrophy (SMA) is a neuromuscular disease caused by mutations inSurvival Motor Neuron 1(SMN1), leading to degeneration of alpha motor neurons (MNs) but also affecting other cell types. Induced pluripotent stem cell (iPSC)-derived human MN models from severe SMA patients have shown relevant phenotypes. We have produced and fully characterized iPSCs from members of a discordant consanguineous family with chronic SMA. We differentiated the iPSC clones into ISL-1+/ChAT+ MNs and performed a comparative study during the differentiation process, observing significant differences in neurite length and number between family members. Analyses of samples from wild-type, severe SMA type I and the type IIIa/IV family showed a progressive decay in SMN protein levels during iPSC-MN differentiation, recapitulating previous observations in developmental studies. PLS3 underwent parallel reductions at both the transcriptional and translational levels. The underlying, progressive developmental decay in SMN and PLS3 levels may lead to the increased vulnerability of MNs in SMA disease. Measurements ofSMNandPLS3transcript and protein levels in iPSC-derived MNs show limited value as SMA biomarkers.
Pupillary light reflex to light inside the natural blind spot
Authors: Miyamoto Kentaro , Murakami Ikuya
Published: June 2015

When a light stimulus covers the human natural blind spot (BS), perceptual filling-in corrects for the missing information inside the BS. Here, we examined whether a filled-in surface of light perceived inside the BS affects the size of the short-latency pupillary light reflex (PLR), a pupil response mediated by a subcortical pathway for unconscious vision. The PLR was not induced by a red surface that was physically absent but perceptually filled-in inside the BS in the presence of a red ring surrounding it. However, a white large disk covering the BS unexpectedly induced a larger PLR than a white ring surrounding the BS border did, even though these two stimuli must be equivalent for the visual system and trial-by-trial percepts did not predict PLR size. These results suggest that some physiological mechanism, presumably the retinal cells containing the photopigment melanopsin, receives the light projected inside the BS and enhances PLR.

Authors: Darris Pierre , Treil Jacques , Marchal-Sixou Christine , Baron Pascal
Published: June 2015

Introduction : Le présent rapport de cas confirme l’hypothèse selon laquelle
l’embryogenèse et la croissance maxillo-faciale sont sous l’influence du système nerveux
périphérique et notamment du nerf trijumeau (V). Il devient intéressant d’utiliser les
stigmates du nerf trijumeau comme référentiel pour analyser tridimensionnellement le
volume maxillo-facial et comprendre sa croissance. L’objectif est d’évaluer la validité de
l’analyse céphalométrique tridimensionnelle d’essence trigéminale de Treil.
Présentation des cas : Le premier cas est un enfant caucasien de sexe
féminin atteint du syndrome de Goldenhar. Le deuxième cas est un adulte caucasien de sexe
masculin atteint du même syndrome. Dans les deux cas, l’IRM cérébrale montre une atteinte
trigéminale unilatérale, homolatérale à l’atteinte faciale. Conclusion : Les
résultats de l’étude radiologique de ces cas de syndrome de Goldenhar tendent à prouver le
rôle matriciel du nerf trijumeau dans la croissance cranio-faciale. Ces cas mettent en
évidence la validité de la conception de la croissance neuro-matricielle de Moss. Ils sont

Zur Entwicklung der ärztlichen Versorgung in stationären Pflegeeinrichtungen – Ergebnisse einer empirischen Untersuchung
Authors: Kleina T. , Horn A. , Suhr R. , Schaeffer D.
Published: June 2015

Nachdem verschiedene Untersuchungen Defizite bei der Versorgung von Heimbewohnern durch Allgemein- und Fachärzte offengelegt haben, hat sich die Diskussion um die Qualität der ärztlichen Versorgung von Bewohnern stationärer Pflegeeinrichtungen in den vergangenen Jahren intensiviert. In Reaktion darauf wurden vonseiten der Politik verschiedene Versuche unternommen, Verbesserungen herbeizuführen. Um ein Bild über die aktuelle Situation in stationären Pflegeeinrichtungen zu gewinnen, wurden Daten zur gesundheitlichen Situation und der medizinischen Versorgung von insgesamt 778 Nutzern aus 8 Pflegeheimen erhoben. Es handelte sich bei ihnen überwiegend um multimorbide Personen, die zahlreiche ärztlich verordnete Medikamente einnahmen. Mit Blick auf die ärztliche Versorgung zeigte sich, dass rund 91% der Bewohner mindestens vierteljährlich persönlichen Kontakt zu Allgemeinmedizinern und/oder Internisten hatten und nur 1,3% von ihnen über einen Zeitraum von einem Jahr keine solchen Kontakte aufwiesen. Dem gegenüber erwies sich die Kontakthäufigkeit zu anderen Fachärzten als vergleichsweise gering. So hatten bspw. nur 18,9% der Nutzer mindestens einmal jährlich Kontakt zu Urologen, nur 16,7% mindestens einmal jährlich Kontakt zu Augenärzten, nur 39,6% mindestens einmal jährlich Kontakt zu Zahnärzten und nur 10,6% der weiblichen Bewohner mindestens einmal jährlich Kontakt zu Gynäkologen. Die Anteile lagen damit – trotz des Vorhandenseins spezifischer medizinischer Problemlagen – unter den Inanspruchnahmequoten älterer Bevölkerungsgruppen, die nicht im Heim leben. Diese Ergebnisse lassen darauf schließen, dass die in den vergangenen Jahren getroffen Maßnahmen zur Optimierung der fachärztlichen Versorgung in Pflegeheimen bislang nur wenig Wirkung entfalten und bekannte Defizite fortbestehen. Angesichts der möglichen Folgen für die Nutzer bedarf es weiterer und intensiverer Anstrengungen zur Verbesserung der haus- und fachärztlichen Versorgung in Einrichtungen der stationären Langzeitversorgung.
Irreconcilability in the Digital: Gender, Technological Imaginings and Maternal Subjectivity
Authors: Thornham Helen
Published: June 2015

Drawing on empirical research from two focus groups, this article investigates the narratives and discourses that emerged around pregnancy, technology, birth and motherhood. In so doing, the article engages in some long-standing debates within feminism around embodied and maternal subjectivity, agency and identity. Seen here, the focus groups serve initially to remind us of the pervasiveness of gender inequality and the continual ambiguity of, and anxieties around, maternal subjectivity. The focus groups reconfigure these issues through a technological lens, which in turn seems to offer new spaces where agency can be (momentarily, problematically) claimed. This in turn extends existing debates in new directions through the particular framework of technology that is variously figured here as an object, as information and as imaginary digital space. All of these constructions, however, become problematic as they—despite their promises—nevertheless ultimately and profoundly return the women to an emplaced, embodied subjectivity that has been at the heart of feminist debate for so long.
3D-printed slit nozzles for Fourier transform microwave spectroscopy
Authors: Dewberry Christopher T. , Mackenzie Rebecca B. , Green Susan , Leopold Kenneth R.
Published: June 2015

3D printing is a new technology whose applications are only beginning to be explored. In this report, we describe the application of 3D printing to the design and construction of supersonic nozzles. Nozzles can be created for $0.50 or less, and the ease and low cost can facilitate the optimization of nozzle performance for the needs of any particular experiment. The efficacy of a variety of designs is assessed by examining rotational spectra of OCS (carbonyl sulfide) and Ar–OCS using a Fourier transform microwave spectrometer with tandem cavity and chirped-pulse capabilities. A slit geometry which, to the best of our knowledge has not been used in conjunction with Fourier transform microwave spectrometers, was found to increase the signal-to-noise ratio for the J = 1←0 transition of OCS, by a factor of three to four compared with that obtained using our standard circular nozzle. Corresponding gains for the Ar–OCS complex were marginal, at best, but further optimization of nozzle geometry should be possible. The spectrometer itself is designed to allow rapid switching between cavity and chirped-pulse modes of operation without the need to break vacuum. This feature, as well as the newly incorporated chirped-pulse capability, is described in detail.
Linear transformation of anharmonic molecular force constants between normal and Cartesian coordinates
Authors: Mackie Cameron J. , Candian Alessandra , Huang Xinchuan , Lee Timothy J. , Tielens Alexander G. G. M.
Published: June 2015

A full derivation of the analytic transformation of the quadratic, cubic, and quartic force constants from normal coordinates to Cartesian coordinates is given. Previous attempts at this transformation have resulted in non-linear transformations; however, for the first time, a simple linear transformation is presented here. Two different approaches have been formulated and implemented, one of which does not require prior knowledge of the translation-rotation eigenvectors from diagonalization of the Hessian matrix. The validity of this method is tested using two molecules H2O and c-C3H2D+.
The effect of Coulomb interactions on nonlinear thermovoltage and thermocurrent in quantum dots
Authors: Zimbovskaya Natalya A.
Published: June 2015

In the present work, we theoretically study the nonlinear regime of charge transport through a quantum dot coupled to the source and drain reservoirs. The investigation is carried out using a nonequilibrium Green’s function formalism beyond the Hartree-Fock approximation. Employed approximations for the relevant Green’s functions allow to trace a transition from Coulomb blockade regime to Kondo regime in the thermoelectric transport. Effects arising when electrons move in response to thermal gradient applied across the system are discussed, including experimentally observed thermovoltage zeros.

In this paper, we present exact solutions of Schrödinger equation for a class of non-central physical potentials within the formalism of position-dependent effective mass. The energy eigenvalues and eigenfunctions of the bound-states for the Schrödinger equation are obtained analytically by means of asymptotic iteration method and easily calculated through a new generalized decomposition of the effective potential allowing easy separation of the coordinates. Our results are in excellent agreement with other works in the literature.

Reactive multilayer foils have the potential to be used as local high intensity heat sources for a variety of applications. Most of the past research effort concerning these materials have focused on understanding the structure-property relationships of the foils that govern the energy released during a reaction. To improve the ability of researchers to more rapidly develop technologies based on reactive multilayer foils, a deeper and more predictive understanding of the relationship between the heat released from the foil and microstructural evolution in the neighboring materials is needed. This work describes the development of a numerical model for the purpose of predicting heat affected zone size in substrate materials. The model is experimentally validated using a commercially available Ni-Al multilayer foils and alloys from the Sn-Bi binary system. To accomplish this, phenomenological models for predicting the variation of physical properties (i.e., thermal conductivity, density, and heat capacity) with temperature and composition in the Sn-Bi system were utilized using literature data.

Composition-gradient electrode materials have been proven to be one of the most promising materials in lithium-ion battery. To study the mechanism of mechanical degradation in spherical composition-gradient electrodes, the finite deformation theory and reversible chemical theory are adopted. In homogeneous electrodes, reversible electrochemical reaction may increase the magnitudes of stresses. However, reversible electrochemical reaction has different influences on stresses in composition-gradient electrodes, resulting from three main inhomogeneous factors—forward reaction rate, backward reaction rate, and reaction partial molar volume. The decreasing transition form of forward reaction rate, increasing transition form of backward reaction rate, and increasing transition form of reaction partial molar volume can reduce the magnitudes of stresses. As a result, capacity fading and mechanical degradation are reduced by taking advantage of the effects of inhomogeneous factors.

Recently, it has been demonstrated that martensitic transformation in nanocrystalline shape memory alloys can be suppressed for small grain sizes. Motivated by these results, we study the grain size dependence of martensitic transformations and stress-strain response of nanocrystalline shape memory alloys within the framework of the Ginzburg-Landau (GL) theory. A GL model for a square to rectangle transformation in polycrystals is extended to account for grain boundary effects. We propose that an inhibition of the transformation in grain boundary regions can occur, if the grain boundary energy of the martensite is higher than that of the austenite phase. We show that this inhibition of transformation in grain boundary regions has a strong influence on domain patterns inside grains. Although the transformation is inhibited only at the grain boundaries, it leads to a suppression of the transformation even inside the grains as grain size is decreased. In fact, below a critical grain size, the transformation can be completely suppressed. We explain these results in terms of the extra strain gradient cost associated with grain boundaries, when the transformation is inhibited at grain boundaries. On the other hand, no significant size effects are observed when transformation is not inhibited at grain boundaries. We also study the grain size dependence of the stress strain curve. It is found that when the transformation is inhibited at grain boundaries, a significant reduction in the hysteresis associated with stress-strain curves during the loading-unloading cycles is observed. The hysteresis for this situation reduces even further as the grain size is reduced, which is consistent with recent experiments. The simulations also demonstrate that the mechanical behavior is influenced by inter-granular interactions and the local microstructural neighbourhood of a grain has a stronger influence than the orientation of the grain itself.

Ohmic contacts to AlGaN grown on sapphire substrates have been previously demonstrated for various compositions of AlGaN, but contacts to AlGaN grown on native AlN substrates are more difficult to obtain. In this paper, a model is developed that describes current flow through contacts to Si-doped AlGaN. This model treats the current through reverse-biased Schottky barriers as a consequence of two different tunneling-dependent conduction mechanisms in parallel, i.e., Fowler-Nordheim emission and defect-assisted Frenkel-Poole emission. At low bias, the defect-assisted tunneling dominates, but as the potential across the depletion region increases, tunneling begins to occur without the assistance of defects, and the Fowler-Nordheim emission becomes the dominant conduction mechanism. Transfer length method measurements and temperature-dependent current-voltage (I-V) measurements of Ti/Al-based contacts to Si-doped AlGaN grown on sapphire and AlN substrates support this model. Defect-assisted tunneling plays a much larger role in the contacts to AlGaN on sapphire, resulting in nearly linear I-V characteristics. In contrast, contacts to AlGaN on AlN show limited defect-assisted tunneling appear to be only semi-Ohmic.

Oxyfluogermanate glasses with good thermal stability were prepared by melt-quenching method. The investigation of 2.7 μm fluorescence spectra and energy transfer mechanism was performed pumped by an 808 nm laser diode. The 2.7 μm radiative transition probability and emission cross section are 32.62 s−1 and 12.88 × 10−21 cm2, respectively. The energy transfer parameters between 4I11/2 and 4I13/2 levels were calculated by Inokuti-Hirayama and Yokota-Tanimoto's model to further elucidate 2.7 μm fluorescent behaviors. It is found that the energy transfer mechanism among Er3+ is mainly dominated by dipole-dipole interactions. Results indicate that the prepared oxyfluogermanate glass is a promising candidate for mid-infrared laser applications.

We report an experimental investigation of magnetic field dependent thermal conductivity of a transformer oil base magnetic fluid as a function of volume fractions. In the absence of magnetic field, thermal conductivity increases linearly with an increase in volume fraction, and magnitude of thermal conductivity thus obtained is lower than that predicted by Maxwell's theory. This reveals the presence of clusters/oligomers in the system. On application of magnetic field, it exhibits a non-monotonous increase in thermal conductivity. The results are interpreted using the concept of a two-step homogenization method (which is based on differential effective medium theory). The results show a transformation of particle cluster configuration from long chain like prolate shape to the aggregated drop-like structure with increasing concentration as well as a magnetic field. The aggregated drop-like structure for concentrated system is supported by optical microscopic images. This shape change of clusters reduces thermal conductivity enhancement. Moreover, this structure formation is observed as a dynamic phenomenon, and at 226 mT field, the length of the structure extends with time, becomes maximum, and then reduces. This change results in the increase or decrease of thermal conductivity.

An AlN piezoelectric Lamb-wave resonator, which is excited by two dimensional electric field, is reported in this paper. Rhombus-shape electrodes are arranged on AlN thin film in a checkered formation. When out-of-phase alternating currents are applied to adjacent checkers, two dimensional acoustic Lamb waves are excited in the piezoelectric layer along orthogonal directions, achieving high electromechanical coupling coefficient, which is comparable to film bulk acoustic resonators. The electromechanical coupling coefficient of the 285.3 MHz resonator presented in this paper is 5.33%, which is the highest among AlN based Lamb-wave resonators reported in literature. Moreover, the spurious signal within a wide frequency range is significantly suppressed to be 90% lower than that of the resonance mode. By varying the electrode dimension and inter-electrode distance, resonators having different resonant frequencies can be fabricated on a single wafer, making single-chip broadband filters, duplexers, and multiplexers possible.

Published: June 2015

Structural, optical, and surface potential properties of CdSe nanoparticles (NPs) prepared on ZnS thin-films have been investigated. CdSe NPs/ZnS thin-films with varying CdSe NPs diameters are synthesised by sequential radio frequency magnetron sputtering technique. A blue shift in the optical absorption edge and enhancement in the optical constants are observed with decrease in the nanoparticles size. CdSe NPs/ZnS thin-films show an absorption edge at about 3.5 eV corresponding to ZnS and another size dependent absorption edge in the energy range of 1.74–2.16 eV, corresponding to CdSe NPs. Decrease in photoluminescence (PL) intensity of ZnS film on incorporation of CdSe NPs is observed; however, no distinct emission peaks corresponding to NPs are seen. Multilayered CdSe NPs/ZnS thin-films comprising of six alternating layers show PL signature both due to ZnS and CdSe NPs. Kelvin probe force microscopy (KPFM) studies show that surface potential values of CdSe NPs/ZnS thin-films lie in between that of ZnS (209 meV) and CdSe/ZnS (−4 meV) thin-films, which confirms charge transfer between CdSe NPs and ZnS thin-films. The evolution of CdSe NPs/ZnS nanoscale heterojunction has been observed with shift in the surface potential values by varying size and coverage of CdSe NPs.

Sputter deposition of oxide materials in a high-pressure oxygen atmosphere is a well-known technique to produce thin films of perovskite oxides in particular. Also interfaces can be fabricated, which we demonstrated recently by growing LaAlO3 on SrTiO3 substrates and showing that the interface showed the same high degree of epitaxy and atomic order as is made by pulsed laser deposition. However, the high pressure sputtering of oxides is not trivial and number of parameters are needed to be optimized for epitaxial growth. Here we elaborate on the earlier work to show that only a relatively small parameter window exists with respect to oxygen pressure, growth temperature, radiofrequency power supply and target to substrate distance. In particular the sensitivity to oxygen pressure makes it more difficult to vary the oxygen stoichiometry at the interface, yielding it insulating rather than conducting.

Published: June 2015

Dynamic behaviors of Zr51Ti5Ni10Cu25Al9 bulk metallic glass were investigated using electric gun and magnetically driven isentropic compression device which provide shock and ramp wave loading respectively. Double-wave structure was observed under shock compression while three-wave structure was observed under ramp compression in 0 ∼ 18GPa. The HEL of Zr51Ti5Ni10Cu25Al9 is 8.97 ± 0.61GPa and IEL is 8.8 ± 0.3GPa, respectively. Strength of Zr51Ti5Ni10Cu25Al9 estimated from HEL is 5.0 ± 0.3GPa while the strength estimated from IEL is 3.6 ± 0.1GPa. Shock wave velocity versus particle velocity curve of Zr51Ti5Ni10Cu25Al9 under shock compression appears to be bilinear and a kink appears at about 18GPa. The Lagrangian sound speed versus particle velocity curve of Zr51Ti5Ni10Cu25Al9 under ramp wave compression exhibits two discontinuances and are divided to three regions: elastic, plastic-I and plastic-II. The first jump-down occurs at elastic-plastic transition and the second appears at about 17GPa. In elastic and plastic-I regions, Lagrangian sound speed increases linearly with particle velocity, respectively. Characteristic response of sound speed in plastic-I region disagree with shock result in the same pressure region(7GPa ∼ 18GPa), but is consistent with shock result at higher pressure(18-110GPa).

Published: June 2015

In this paper, first, by introducing Holstein-Primakoff representation of α-deformed algebra, we achieve the associated non-linear coherent states, including su(2) and su(1, 1) coherent states. Second, by using waveguide lattices with specific coupling coefficients between neighbouring channels, we generate these non-linear coherent states. In the case of positive values of α, we indicate that the Hilbert size space is finite; therefore, we construct this coherent state with finite channels of waveguide lattices. Finally, we study the field distribution behaviours of these coherent states, by using Mandel Q parameter.
