Mean field ring polymer molecular dynamics for electronically nonadiabatic reaction rates
Authors: Duke Jessica Ryan , Ananth Nandini
Published: June 2016

We present a mean field ring polymer molecular dynamics method to calculate the rate of electron transfer (ET) in multi-state, multi-electron condensed-phase processes. Our approach involves calculating a transition state theory (TST) estimate to the rate using an exact path integral in discrete electronic states and continuous Cartesian nuclear coordinates. A dynamic recrossing correction to the TST rate is then obtained from real-time dynamics simulations using mean field ring polymer molecular dynamics. We employ two different reaction coordinates in our simulations and show that, despite the use of mean field dynamics, the use of an accurate dividing surface to compute TST rates allows us to achieve remarkable agreement with Fermi's golden rule rates for nonadiabatic ET in the normal regime of Marcus theory. Further, we show that using a reaction coordinate based on electronic state populations allows us to capture the turnover in rates for ET in the Marcus inverted regime.

Finite element and neural network approach for positioning a magnetic shunt on the tank wall of a transformer
Authors: Díaz‐Chacón Juan M. , Hernandez Concepción , Arjona Marco A.
Published: June 2016

Manufacturers reduce stray losses in transformers by using magnetic shunts. These losses may cause hot spots in metallic structural parts of transformers such as the tank wall and frames. The calculation of the reduction of the stray losses on the tank wall using magnetic shunts is a complex task. In this study, a method for determining the position of a magnetic shunt and reducing the stray losses on the tank wall of a transformer is presented. Feed‐forward neural networks (FFNNs) and the finite element method are employed. The Latin hypercube sampling is used to achieve a reduced number of training cases. Afterwards, several two‐dimensional finite‐element axisymmetric models of a transformer are solved and used as training data for two FFNN models. A comparison with finite‐element models is carried out to evaluate the proposed method. Finally, a case study is solved using this method. The approach offers an alternative method to predict and reduce the intensity of the stray losses on the tank wall of the transformer in a straightforward way.
Super‐speed up robust features image geometrical registration algorithm
Authors: Na Yan , Liao Mengmeng , Jung Cheolkon
Published: June 2016

Speed up robust features (SURF) image geometrical registration algorithm available tends to have a one‐to‐many association problem in feature association. One feature point in an image is associated with multiple feature points in another image, of which some or even all are mismatching points. Coordinates of these mismatching points are used to compute transformation matrix, making it difficult to obtain desirable registration. To solve this problem of SURF algorithm, super‐SURF image geometrical registration algorithm is proposed, in which information richness areas are selected to detect feature points and to implement feature points association. The degree of closeness of multiple feature points from the one‐to‐many feature point pairs is analysed in order to remove feature point pairs with larger errors and retain those with smaller errors. Transformation matrix is then determined with coordinates of feature point pairs retained. Registration image can be obtained after transformation of floating image. Experimental results indicate that super‐SURF image geometrical registration algorithm is of higher matching accuracy with less running time than SURF algorithm.
Joint relay selection and power allocation in energy harvesting AF relay systems with ICSI
Authors: Zhang Yangyang , Ge Jianhua , Men Jinjin , Ouyang Fengchen , Zhang Chensi
Published: June 2016

In various wireless networks, power allocation scheme promises significant benefits in energy harvesting (EH) wireless networks. However, these benefits depend on the knowledge of the channel state information (CSI), which is hardly perfect. Therefore, in this study, the authors investigate an EH two‐way relaying network with channel estimation error taking into consideration. First, the system outage performance is studied and closed‐form expressions for the outage probability are derived. On the basis of minimising the outage probability, an optimal power allocation (OPA) scheme is proposed and the effective ways to solve this OPA scheme are presented. In addition, a joint relay selection and the OPA scheme is provided to further improve the system performance. Finally, by comparing the OPA scheme with conventional power allocation schemes via simulations, the superiority of the OPA scheme is demonstrated. Moreover, the impact of imperfect CSI on the system performance is analysed and the simulation results show the robustness of the OPA scheme.
Efficient design of a radome for minimised transmission loss
Authors: Sheret Tamara , Parini Clive , Allen Ben
Published: June 2016

A radome has to be carefully designed to ensure it has minimum impact on the performance of the antenna. Traditional approaches involve equation approximations, complex ray tracing, iterative manufacturing process and or electrically large and lengthy electromagnetic (EM) simulations. The novel approach described in this study involves a two‐dimensional ray tracing method simulation in MATLAB and an electrically small unit cell simulation in high‐frequency structure simulator. This new approach gives an optimal thickness result that is only 0.004 mm different to that of a full EM simulation. The radome is manufactured and radio‐frequency tested in an anechoic chamber, the calculated thickness is shown to be the optimal thickness.
Review on pulse‐width modulation strategies for common‐mode voltage reduction in three‐phase voltage‐source inverters
Authors: Chen Henglin , Zhao Huan
Published: June 2016

With wide application of inverters in modern industry, common‐mode voltage (CMV) problems invoked severe negative effects. Hardware and software solutions have been proposed to reduce the CMV. Compared with hardware CMV mitigation solutions, software strategies based on pulse‐width modulation (PWM) modifications have aroused widespread attention for their cost‐effective and control flexible advantages. Up to date, various reduced CMV PWM (RCMV‐PWM) strategies have been reported, such as active zero state PWM, remote state PWM, near state PWM, phase‐shifted carrier PWM, carrier peak position modulation and so on. For convenience of understanding and utilising the existed RCMV‐PWM strategies, this study conducts a review on this topic. According to the principle of CMV reduction algorithms, the study divides the reported RCMV‐PWM strategies into three different categories. It also presents comparisons of CMV reduction techniques and output performances (like CMV value, output ripple and linearity range) between different strategies. Meanwhile, CMV suppression principles, problems in implementation and improvements of each technique are described in detail. Moreover, the inherent characteristics and development tendencies of the RCMV‐PWM techniques are discussed so as to offer reference for further research.

Reliability Criteria for Liver Stiffness Measurements with Real-Time 2D Shear Wave Elastography in Different Clinical Scenarios of Chronic Liver Disease
Authors: Thiele Maja , Madsen Bjørn , Procopet Bogdan , Hansen Janne , Møller Linda , Detlefsen Sönke , Berzigotti Annalisa , Krag Aleksander
Published: June 2016

Purpose Liver stiffness measurement by real-time 2-dimensional shear wave elastography (2D-SWE) lacks universal reliability criteria. We sought to assess whether previously published 2D-SWE reliability criteria for portal hypertension were applicable for the evaluation of liver fibrosis and cirrhosis, and to look for criteria that minimize the risk of misclassification in this setting.

Materials and Methods In a biopsy-controlled diagnostic study, we obtained five 2D-SWE measurements of optimal image quality. Correctly classified cases of fibrosis and cirrhosis were compared to misclassified cases. We compared reliability predictors (standard deviation (SD), SD/mean, size of region of interest (ROI) and difference between a single measurement and the patient’s median) with those obtained in a prior study on clinically significant portal hypertension.

Results We obtained 678 2D-SWE measurements from 142 patients. Overall, the variability in liver stiffness within single 2D-SWE measurements was low (SD = 1.1 ± 1.5kPa; SD/mean = 12 ± 9 %). Intra-observer analysis showed almost perfect concordance (intraclass correlation coefficient = 0.95; 95 % CI 0.94 – 0.96; average difference from median = 0.4 ± 0.9kPa). For the diagnosis of cirrhosis, a smaller SD (optimally ≤ 1.75 kPa) and larger ROI size (optimally ≥ 18 mm) were associated with higher accuracy. Similarly, within the published cohort of patients assessed for portal hypertension, a low variability of measurements was associated with high reliability.

Conclusion A high quality 2D-SWE elastogram ensures low variability and high reliability, regardless of indication. We recommend aiming for a combination of low standard deviation and large ROI.
Apathy, excitement and resistance: teaching feminism in business and management schools
Authors: Sang Katherine , Glasgow Steven
Published: June 2016

Feminism, gender and women’s issues have been side-lined within business and management studies in the United Kingdom, evidenced by the inclusion of only one highly ranked gender journal in the recent ABS journal quality list. While there have been some efforts to critique gendered research norms within business and management schools, less is known about the experiences of those engaged in designing and delivering curricula. This article begins by examining the extant literature on the experiences of feminist academics, leading to a discussion of the limited research on business and management schools. It then moves to a description of the methods adopted, namely, qualitative interviews with academics engaged in feminist teaching, and reflections from the authoring team. The findings are presented, highlighting how participants conceptualize feminism, the use of feminism in curricula development, and how the academic community responds to the teaching of feminism. The article concludes with a consideration of areas for future research. The study contributes to the understanding of the experiences of working within the contemporary business school, specifically for academics engaged in a social justice approach to teaching. It identifies that experiences are not universal, with feminism creating space for excitement for both staff and students, but potentially increasingly vulnerability for isolation and marginalization. This article is published as part of a thematic collection on gender studies.
A fine balance: individualism, society and the prevention of mental illness in the United States, 1945–1968
Authors: Smith Matthew
Published: June 2016

In the introduction to a collection of his essays entitled Society as Patient (1950), American social scientist and Rockefeller Foundation administrator Lawrence K Frank (1890–1968) claimed that, to prevent the apparently escalating rates of mental illness: “The individual, instead of seeking his own personal salvation and security, must recognize his almost complete dependence upon the group life and see his only hope in and through cultural reorganization”. Americans, Frank continued, would have “to give up … time-honored beliefs in human volition and responsibility” and “replace them with a larger and humanly more valuable belief in cultural self-determination, social volition, and group responsibility”. For Americans entering the 1950s, a decade of postwar prosperity, McCarthyism and free market capitalism, such communitarian thinking might have been anathema. But also arising out of the American experience of the Second World War were mounting concerns about mental health, due in part to the large number of American military recruits rejected on psychiatric grounds and American soldiers granted psychiatric discharge. In the face of affluence and contentment was alarm that many more Americans were mentally disordered than previously thought, and that new preventive approaches to mental health were required. Addressing these concerns during the postwar period was a new approach to psychiatry: social psychiatry. Rooted in both the child guidance and mental hygiene movements of the early twentieth century as well as contemporary social scientific research, social psychiatry was “a preventive psychiatry”, an epidemiological approach to mental health dedicated to identifying the environmental causes of mental illness—ranging from overcrowding and poverty to social exclusion and racism—and eradicating them. In this article, I explore how the economic and social implications of social psychiatry were articulated. Did social psychiatrists believe that it was possible to re-balance American society, not merely in economic terms, but also with respect to counter-balancing the prevailing ideology of “rugged individualism” with a more communitarian outlook? To what degree were they willing to do this themselves, eschewing lucrative psychoanalytic practices for community psychiatry? I will suggest that, although many of the aspirations of social psychiatry were unrealistic, and possibly utopian, they are worth re-considering.

Five years after Fukushima: scientific advice in Japan
Authors: Sato Yasushi , Arimoto Tateo
Published: June 2016

In the last 5 years, scientific advice has emerged as a new policy theme in Japan. In 2010, virtually no one in Japan’s science policy circle spoke of scientific advice. By 2015, Japan was proactively involved in international discussions on scientific advice, and both the government and the scientific community recognized it as a key area of concern. This article describes how the issue of scientific advice came to attain recognition in Japan’s science policy community in the first half of the 2010s. It can be regarded as a study of a case in which attention to scientific advice greatly increased in a relatively short period of time and progress towards the goal of constructing an effective national scientific advisory system was witnessed. In Japan’s case, two coinciding developments powerfully drove the phenomenon observed: the unfolding of debate on the roles and responsibilities of scientists and the government, prompted by the Great East Japan Earthquake and the ensuing tsunami and nuclear disaster in March 2011; and a parallel surge in attention to scientific advice in the international community. Having considered the path that Japan has taken, the last part of this article will call for the nation’s sustained effort to be engaged in ongoing international endeavours to strengthen scientific advice. This article is published as part of a collection on scientific advice to governments.

Growth and stability of rocksalt Zn1−xMgxO epilayers and ZnO/MgO superlattice on MgO (100) substrate by molecular beam epitaxy

Zn1−xMgxO films with x = 0.04–0.50 grown on MgO (100) substrates by molecular beam epitaxy retain the rocksalt (rs) crystal structure and grow epitaxially for x ≥ 0.17. In addition, the rs-ZnO epilayer is observed to be stable up to a thickness of 5 nm and also in a ZnO/MgO superlattice sample. However, a portion of the superlattice has transformed to wurtzite (wz)-structure islands in a self-accommodated manner during growth. The transformation is a combination of a Bain distortion, an in-plane rotation of 14.5°, and a Peierls distortion, resulting in an orientation relationship of (100)rs//(101̄0)wz and 〈011〉rs ∼//〈1̄21̄3〉wz. In such a manner, the volume expansion is only necessary along the growth direction and the in-plane strains can be minimized. A negative pressure generated during the transformation of ZnO stabilizes the MgO into a wurtzite structure.

Renewable energy sources (RES) can be a significant source of profit. However, different RES projects can bring various benefits to their investors, raising the question—Which RES project to select? The objective of this study is to provide answers to two questions: (1) Which factors/criteria should be used in the RES project selection procedure; (2) Which RES project should the investor select out of a group of prospective projects? The study was conducted in a company operating in the energy sector in Serbia. In order to find answers to the above-mentioned questions, the study employed a hybrid methodology integrating the SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis and the Analytical Hierarchy Process (AHP). First, the Company's management defined the goal and project alternatives. The goal was to select an optimal RES project suitable for the specific circumstances in the Serbian energy sector, and also for the Company's potentials. The alternatives included: a hydro energy project, a solar energy project, a wind energy project (WEP), and a biomass energy project. Then, the decision-making group was formed, consisting of four company's experts (hereinafter collectively referred to as “the decision-makers”), of different professional backgrounds and affiliations. Second, the decision-makers employed SWOT analysis on the RES projects in Serbia to obtain the decision-making criteria. The decision-making procedure has to be based on 20 SWOT factors. However, each criterion is not of equal importance for investors. This shortcoming has been overcome by introducing AHP. Pairwise comparison was performed using the Expert Choice 2000 software. According to the results, the top-ranking project is the WEP.

Absolute frequencies of unperturbed 12C16O transitions from the near-infrared (3–0) band were measured with uncertainties five-fold lower than previously available data. The frequency axis of spectra was linked to the primary frequency standard. Three different cavity enhanced absorption and dispersion spectroscopic methods and various approaches to data analysis were used to estimate potential systematic instrumental errors. Except for a well established frequency-stabilized cavity ring-down spectroscopy, we applied the cavity mode-width spectroscopy and the one-dimensional cavity mode-dispersion spectroscopy for measurement of absorption and dispersion spectra, respectively. We demonstrated the highest quality of the dispersion line shape measured in optical spectroscopy so far. We obtained line positions of the Doppler-broadened R24 and R28 transitions with relative uncertainties at the level of 10−10. The pressure shifting coefficients were measured and the influence of the line asymmetry on unperturbed line positions was analyzed. Our dispersion spectra are the first demonstration of molecular spectroscopy with both axes of the spectra directly linked to the primary frequency standard, which is particularly desirable for the future reference-grade measurements of molecular spectra.

The relationship between the effective bandgap and the crystalline structure in ordered InAsSb material has been studied. Modulation of the As/Sb ratio was induced along the growth direction during molecular beam epitaxy, producing a strained layer superlattice. To enable the use of concentration ratios near unity in both layers in the period, the structures were grown with negligible net strain on a virtual substrate with a lattice constant considerably larger than that of GaSb. The bandgap line-up of InAsSb layers with different compositions is such that a type II superlattice is formed, which exhibits smaller bandgaps than either of the two constituents. It can also be smaller than the possible minimum direct-bandgap of the alloy. From observations of CuPt ordering in bulk layers with small amounts of strain of both signs, we postulate that strain is the main driving force for atomic ordering in InAsSb. Because the modulated structures exhibit small but opposing amounts of strain, both layers in the period exhibit ordering at the atomic scale throughout the structure. Since the strain can be controlled, the ordering can be controlled and sustained for arbitrary thick layers, unlike the situation in uniform bulk layers where the residual strain eventually leads to dislocation formation. This offers a unique way of using ordering at two different scales to engineer the band-structure.
Three-dimensional atomic force microscopy mapping at the solid-liquid interface with fast and flexible data acquisition
Authors: Söngen Hagen , Nalbach Martin , Adam Holger , Kühnle Angelika
Published: June 2016

We present the implementation of a three-dimensional mapping routine for probing solid-liquid interfaces using frequency modulation atomic force microscopy. Our implementation enables fast and flexible data acquisition of up to 20 channels simultaneously. The acquired data can be directly synchronized with commercial atomic force microscope controllers, making our routine easily extendable for related techniques that require additional data channels, e.g., Kelvin probe force microscopy. Moreover, the closest approach of the tip to the sample is limited by a user-defined threshold, providing the possibility to prevent potential damage to the tip. The performance of our setup is demonstrated by visualizing the hydration structure above the calcite (10.4) surface in water.

We report on the preparation and thermoelectric properties of the quaternary system AgPbmBiTe2+m (Bismuth-Lead-Silver-Tellurium, BLST-m) that were nanostructured by mechanical alloying. Nanopowders of various compositions were compacted by three different methods: cold pressing/annealing, hot pressing, and short term sintering. The products are compared with respect to microstructure and sample density. The thermoelectric properties were measured: thermal conductivity in the temperature range from 300 K to 800 K and electrical conductivity and Seebeck coefficient between 100 K and 800 K. The compacting method and the composition had a substantial impact on carrier concentration and mobility as well as on the thermoelectric parameters. Room temperature Hall measurements yielded carrier concentrations in the order of 1019 cm−3, slightly increasing with increasing content of the additive silver bismuth telluride to the lead telluride base. ZT values close to the ones of bulk samples were achieved. X-ray diffraction and transmission electron microscopy (TEM) showed macroscopically homogeneous distributions of the constituting elements inside the nanopowders ensembles, indicating a solid solution. However, high resolution transmission electron microscopy (HRTEM) revealed disorder on the nanoscale inside individual nanopowders grains.

Calculations of Debye-Scherrer diffraction patterns from polycrystalline materials have typically been done in the limit of small deviatoric stresses. Although these methods are well suited for experiments conducted near hydrostatic conditions, more robust models are required to diagnose the large strain anisotropies present in dynamic compression experiments. A method to predict Debye-Scherrer diffraction patterns for arbitrary strains has been presented in the Voigt (iso-strain) limit [Higginbotham, J. Appl. Phys. 115, 174906 (2014)]. Here, we present a method to calculate Debye-Scherrer diffraction patterns from highly stressed polycrystalline samples in the Reuss (iso-stress) limit. This analysis uses elastic constants to calculate lattice strains for all initial crystallite orientations, enabling elastic anisotropy and sample texture effects to be modeled directly. The effects of probing geometry, deviatoric stresses, and sample texture are demonstrated and compared to Voigt limit predictions. An example of shock-compressed polycrystalline diamond is presented to illustrate how this model can be applied and demonstrates the importance of including material strength when interpreting diffraction in dynamic compression experiments.

We describe an experiment on the use of a fore-vacuum-pressure, plasma-cathode, electron beam source with current up to 100 mA and beam energy up to 15 keV for deposition of Mg and Al oxide films on Si substrates in an oxygen atmosphere at a pressure of 10 Pa. The metals (Al and Mg) were evaporated and ionized using the electron beam with the formation of a gas-metal beam-plasma. The plasma was deposited on the surface of Si substrates. The elemental composition of the deposited films was analyzed.
