Published: August 2017

AbstractWe are briefly reviewing the current status of elastic strain field determination in III–V heteroepitaxial nanostructures, linking finite elements (FE) calculations with quantitative nanoscale imaging and atomistic calculation techniques. III–V semiconductor nanostructure systems of various dimensions are evaluated in terms of their importance in photonic and microelectronic devices. As elastic strain distribution inside nano-heterostructures has a significant impact on the alloy composition, and thus their electronic properties, it is important to accurately map its components both at the interface plane and along the growth direction. Therefore, we focus on the determination of the stress-strain fields in III–V heteroepitaxial nanostructures by experimental and theoretical methods with emphasis on the numerical FE method by means of anisotropic continuum elasticity (CE) approximation. Subsequently, we present our contribution to the field by coupling FE simulations on InAs quantum dots (QDs) grown on (211)B GaAs substrate, either uncapped or buried, and GaAs/AlGaAs core-shell nanowires (NWs) grown on (111) Si, with quantitative high-resolution transmission electron microscopy (HRTEM) methods and atomistic molecular dynamics (MD) calculations. Full determination of the elastic strain distribution can be exploited for band gap tailoring of the heterostructures by controlling the content of the active elements, and thus influence the emitted radiation.
Long QT syndrome diagnosed in two sisters with propionic acidemia: a case report
Authors: Duras Ensar , İrdem Ahmet , Özkaya Ozan 
Published: August 2017

AbstractPropionic acidemia (PA) is a rare autosomal recessive metabolic disorder caused by deficiency of the mitochondrial enzyme propionyl-CoA carboxylase (PCC). This disorder mostly progresses with episodes of metabolic acidosis. Cardiomyopathy is among the cardiac complications known to occur during metabolic decompensation episodes. However, several recent papers emphasized the association of PA and long QT syndrome (LQTS) which may lead to extremely serious and fatal consequences. In this report, we describe two sisters with PA who have prolonged QT duration that were incidentally detected in an outpatient setting. LQTS was verified by electrocardiogram, stress test and 24 h rhythm holter monitoring. By this report, we want to emphasize the importance of early diagnosis of LQTS in asymptomatic patients with PA to prevent fatal complications.
A Dynamic Model of Procurement Risk Element Transmission in Construction Projects
Authors: Li Cunbin , Liu Yunqi , Li Shuke 
Published: August 2017

AbstractThe cost of materials is the largest proportion of a construction project’s total budget. If the materials cannot be delivered to the construction site on time, completely and with acceptable quality, the project’s duration and cost will be greatly affected. Based on the generalized project risk element transmission theory and system dynamics, a system dynamics model was developed to capture dynamics of procurement risk elements transmission during construction projects and how various procurement risk elements affect the project’s duration and cost by simulation. In this paper, procurement risk element is considered as the uncertain factors in procurement. Based on these results, it is concluded that the developed model can provide important information for risk managers and project managers addressing procurement risk.

Authors: Bin Ning , Zhang Chengke , Zhu Huainian , Mo Zan 
Published: August 2017

AbstractBased on singularly perturbed bilinear quadratic problems, this paper proposes to decompose the full-order system into two subsystems of a slow-time and fast-time scale. Utilizing the fixed point iterative algorithm to solve cross-coupled algebraic Riccati equations, equilibrium strategies of the two subsystems can be obtained, and further the composite strategy of the original full-order system. It was proved that such a composite strategy formed ano(ε) (near) Stackelberg equilibrium, and a numerical result of the algorithm was presented in the end.

Authors: Zhu Huijie , Wang Xinqing , Li Yanfeng , Liu Mengxi , Liu Tianshuai 
Published: August 2017

AbstractIn this paper, a new approach to rolling bearing diagnosis is proposed, which applied orthogonal matching pursuit with pulse atoms. Solving orthogonal matching pursuit with pulse atoms (OMP_PA) is an NP-hard problem. With the help of multi-population genetic algorithm, better solution is obtained, and the shortcoming of sensitiveness to parameters setting in genetic algorithm is improved. According to the comparisons with other algorithms, OMP_PA could precisely extract the pulse components, and the interferential components are almost filtered. The experiments show that, OMP_PA could determine the fault location of bearings, and clearly displayed the vibration model. In conclusion, it provides a new way to the diagnosis for bearings.
The GM(1,1) Model Optimized by Using Translation Transformation Method and Its Application of Rural Residents’ Consumption in China
Authors: Liu Chong , Yang Cui 
Published: August 2017

AbstractConventional GM(1,1) model shows some limitations which affect directly to the model applicability as well as prediction accuracy. In order to improve the disadvantages existing in the original grey model, the authors analyze the translation transformation approach to optimize the raw sequence for grey modeling. This paper mainly carries on the proof of the existence of translation transformation from the perspective of smooth ratio and gives the method to solve the best step size of translation transformation. Then, the authors applied the grey models optimized by translation transformation to analyze the problem of the consumption of rural residents in China. As a result, the authors find GM(1,1) model optimized by translation transformation has characteristics of higher accuracy and simple calculation process and an important practical application in residents consumption.
The Estimate of Capital Services by Sector in China
Authors: Xi Wei , Xu Jun 
Published: August 2017

AbstractMeasuring the contribution of capital to productivity is always an important issue in economics. With the concept of capital service introduced in SNA2008, there are some changes in capital accounting itself. Particularly, R&D expenditure has been recognized as part of capital formation for the first time in SNA2008. This part new capital formation changes the size of GDP. It has a profound impact on capital accounting. In this paper, the hyperbolic age-efficiency profile model is applied to measure the capital input of 86 sectors in China from 2002 to 2012. Endogenous rate of return and exogenous rate of return are used respectively to measure six fixed assets capital service index including R&D assets. Meanwhile, the implement of the sensitivity analysis for different assets and rates of return is used to identify the key factors that can affect the measurement of capital services. Moreover, this paper can also provide data and literature reference for researches on quantifying the capital’s contribution to economic growth.
An Empirical Study of Employees’ Tacit Knowledge Sharing Behavior
Authors: Wang Juanru , Yang Jin 
Published: August 2017

AbstractThis paper is to investigate how employees’ tacit knowledge sharing behavior is influenced by various antecedents. We propose that tacit knowledge sharing consists of three specific behaviors (i.e., socialization, externalization, and internalization) and they are influenced by four antecedents (trust, self-efficacy, knowledge tacitness, and IT support). A survey was conducted to collect data from 258 knowledge workers who worked on complex product development projects. Structural equation modeling was used to analyze the data. The results demonstrate that trust, self-efficacy, knowledge tacitness, and IT support significantly affect the externalization and internalization behaviors, and trust and IT support significantly affect the socialization behavior. This study is helpful to organizations where it is critical for employees to share tacit knowledge. It suggests that tacit knowledge is difficult to share and organizations should nurture mutual trust between employees, enhance their self-efficacy, and provide sufficient IT support so that they are more likely to engage in tacit knowledge sharing.
On the Sparseness and Generalization Capability of Least Squares Support Vector Machines
Authors: Yan Aijun , Huang Xiaoqian , Shao Hongshan 
Published: August 2017

AbstractCompared with standard support vector machines (SVM), sparseness is lost in the modeling process of least squares support vector machines (LS-SVM), causing limited generalization capability. An improved method using quadratic renyi-entropy pruning is presented to deal with the above problems. First, a kernel principal component analysis (KPCA) is used to denoise the training data. Next, the authors use the genetic algorithm to estimate and optimize the kernel function parameter and penalty factor. Then, pick the subset that has the largest quadratic entropy to train and prune, and repeat this process until the cumulative error rate reaches the condition requirement. Finally, comparing experiments on the data classification and regression indicates that the proposed method is effective and may improve the sparseness and the generalization capability of LS-SVM model.
Multilateral Development Banks and Sustainable Development: On Emulation, Fragmentation and a Common Law of Sustainable Development
Authors: Mbengue Makane Moïse , de Moerloose Stéphanie 
Published: August 2017

AbstractMultilateral Development Banks (hereinafter MDBs) have evolved from avoiding non-economic considerations, as required in most of their charters, to officially supporting sustainable development. This transformation is due not only to international law, civil society pressure or internal adjustments, but in part to the emulation phenomenon between the international effort for sustainable development made by international conferences and commissions and the sustainable development effort by MDBs. The paper first examines this emulation phenomenon and its strong impact on MDB creation of substantive instruments – the environmental and social safeguards – and of procedural instruments – the accountability mechanisms – for the integration of sustainable development. Following this discussion, the second part points out that MDBs’ environmental and social safeguards still differ substantially, revealing a fragmentation in MDBs’ normative understanding of sustainable development. After presenting the arguments supporting this fragmentation, the last part of the paper argues in favor of the harmonization of MDBs’ environmental and social safeguards, resulting in the creation of a common law of sustainable development, the promotion of international law and the facilitation of investments.

Published: August 2017

Abstract
Organophosphorus chemistry was developed in the last decade by promoting the synthesis reactions using ionic liquids either as solvent or catalyst. Ionic liquids (ILs), the so-called “green solvents”, have gained interest in the synthesis of organophosphorus compounds as alternatives to flammable and toxic organic solvents and catalysts. ILs have beneficial properties because they provide high solubility for many organic and inorganic compounds or metal complexes, have no vapor pressure, and are reusable. Also, in some cases, they can enhance the reactivity of chemical reagents. In this review, we aimed at showing the synthesis of different organophosphorus compounds under green and mild conditions using ILs as reaction media or catalysts, according to a trend developed in the last years. A novel trend is to perform these syntheses under microwave irradiation conditions together with ILs as solvents and catalysts.
La sémiotique des formes de vie, un nouveau tournant ?
Authors: Marion Colas-Blaise 
Published: August 2017

Résumé Ce compte rendu de Formes de vie de Jacques Fontanille (Liège, Presses universitaires de Liège, coll. « Sigilla », 2015a, 274 p.) cherche à montrer que l’ouvrage s’inscrit dans une certaine continuité, notamment par rapport à Pratiques sémiotiques (2008), mais qu’il constitue aussi un nouveau tournant, qui fait évoluer la sémiotique et la positionne dans le champ des sciences humaines et sociales. D’abord, nous discutons le fait que, selon Jacques Fontanille, les formes de vie font « vaciller » la frontière entre la nature et la culture. Nous soulignons le fait que Jacques Fontanille développe après Descola, Latour et Lotman les notions de régimes de croyance d’identification, de mode d’existence social et de sémiosphère. Ensuite, l’accent est mis sur le « vivre-avec » comme macro-expérience. Il s’agit de mesurer les conséquences d’un double choix qui permet de dépasser le stade de l’auto-organisation : d’une part, le rapport au monde est médié par l’actant-corps ; d’autre part, l’activité sémiotique consciente d’elle-même est une activité méta-sémiotique. Enfin, il importe d’évaluer la part du culturel dans la constitution des formes de vie. Nous nous interrogeons sur l’« instanciation » des formes de vie dans un lieu et dans un temps déterminés.
The semiotic abstraction
Authors: Daylight Russell 
Published: August 2017

AbstractWhen we press the “A” key on our computer keyboard, an “a” appears on our screen almost simultaneously. In between those two points there are a number of layers of computer program which communicate with each other: the keyboard controller sends a message to the operating system which is interpreted by a word processor, which then returns a message to the operating system, which communicates with the video controller and the video board sends a message that it needs an “a” and this is mapped as a group of pixels which light up on the screen. Except that none of this actually happens. At the level of physical reality, all that happens is the shifting of magnetic fields and the passing of electrons. The electrons orbiting atoms slide from one atom to the next along wires, among silicon and metal. Entities like computer programs and operating systems are
Que peut la théorie greimassienne pour une sémiotique de la perception? Enquête et perspectives
Authors: Moutat Audrey 
Published: August 2017

Résumé
Partant de la considération inaugurale de Sémantique structurale selon laquelle « la perception [constitue] le lieu non linguistique où se situe l’appréhension de la signification », cet article propose de revenir sur les propositions greimassiennes à l’égard du « niveau du vécu et du senti ». Il s’agira de reconsidérer la définition du monde naturel, et notamment la question de son être dissimulé par son paraître à l’origine de son imperfection, avant de convoquer l’héritage greimassien à l’aune d’une sémiotique tournée vers de nouveaux objets sensibles. Notre objectif consiste ainsi à observer les remaniements et réorientations théoriques post-greimassiens à l’égard des problématiques de la perception et d’un monde sensible contemporain.
A new recognition algorithm for “head-and-shoulders” price patterns

Published: August 2017

Abstract
Savin et al. [Savin, G., P. Weller, and J. Zvingelis. 2007. “The Predictive Power of “Head-and-Shoulders” Price Patterns in the US Stock Market.” Journal of Financial Econometrics 5: 243–265.] and Lo et al. [Lo, A. W., H. Mamaysky, and J. Wang. 2000. “Foundations of Technical Analysis: Computational Algorithms, Statistical Inference, and Empirical Implementation.” Journal of Finance 55: 1705–1765.] analysed the predictive power of head-and-shoulders (HS) patterns in the U.S. stock market. The algorithms in both studies ignored the relative position of the HS pattern in a price trend. In this paper, a filter that removes invalid HS patterns is proposed. It is found that the risk-adjusted excess returns for the HST pattern generally improve through the use of our filter.
Markov-switching quantile autoregression: a Gibbs sampling approach
Authors: Liu Xiaochun , Luger Richard 
Published: August 2017

AbstractWe extend the class of linear quantile autoregression models by allowing for the possibility of Markov-switching regimes in the conditional distribution of the response variable. We also develop a Gibbs sampling approach for posterior inference by using data augmentation and a location-scale mixture representation of the asymmetric Laplace distribution. Bayesian calculations are easily implemented, because all complete conditional densities used in the Gibbs sampler have closed-form expressions. The proposed Gibbs sampler provides the basis for a stepwise re-estimation procedure that ensures non-crossing quantiles. Monte Carlo experiments and an empirical application to the U.S. real interest rate show that both inference and forecasting are improved when the quantile monotonicity restriction is taken into account.
Schrift und Charisma: Zur Rolle von Lehrbüchern in der pfingstlich-charismatischen Mission in Subsahara-Afrika
Authors: Spies Eva 
Published: August 2017

ZusammenfassungDer Beitrag befasst sich mit den Schriften von Dag Heward-Mills, dem Gründer der pfingstlich-charismatischen Lighthouse Chapel International aus Ghana. Ich argumentiere, dass er mit der Verbreitung seiner Schriften versucht, eine transnationale Textgemeinschaft zu begründen, die sich über eine gemeinsame Lesart pfingstlicher Inhalte konstituiert und die sich in spezifischen Organisationsformen materialisieren soll. Während sozialwissenschaftliche Pfingstkirchenforschung heute eher sinnlich-emotionale Formen der Vergemeinschaftung und neue Medien untersucht, betont der Aufsatz die Bedeutung von Text und standardisierter Lehre für die Gemeinschaftsbildung. In seinen Schriften präsentiert sich Heward-Mills als ‚gesalbter‘ Autor, der Wissen mit Charisma verbindet und daraus organisatorische Strukturen ableitet. Die Schriften zielen also nicht nur auf die Institutionalisierung einer Pfingstkirche, sondern sind vielmehr auch ein Versuch der Charismatisierung des Institutionellen durch den Kirchengründer selbst.

Objective
Germline loss-of-function mutations in succinate dehydrogenase (SDHx) genes results in rare tumor syndromes that include pheochromocytoma, paraganglioma, and others. Here we report a case series of patients with adrenocortical carcinoma (ACC) that harbor SDHx mutations.

Patients and results
We report four unrelated patients with ACC and SDHx mutations. All cases presented with Cushing syndrome and large adrenal masses that were confirmed to be ACC on pathology. All four ACC specimens were found to have truncating mutations in either SDHC or SDHA, while cases 1, 2 and 3 also had the mutations confirmed in the germline: Case 1: SDHC c.397C > T, pR133X; Case 2: SDHC c.43C > T, p.R15X; Case 3: SDHA c.91C > T, p.R31X; Case 4: SDHA c.1258C > T, p.Q420X. Notably, Case 1 had a father and daughter who both harbored the same SDHC germline mutation, and the father had a paraganglioma and renal cell carcinoma. A combination of next generation sequencing, and/or immunohistochemistry, and/or mass spectroscopy was used to determine whether there was loss of heterozygosity and/or loss of SDH protein expression or function within the ACC. Potential evidence of loss of heterozygosity was observed only in Case 2.

Conclusions
We observed truncating mutations in SDHA or SDHC in the ACC and/or germline of four unrelated patients. Given how statistically improbable the concurrence of ACC and pathogenic germline SDHx mutations is expected to be, these observations raise the question whether ACC may be a rare manifestation of SDHx mutation syndromes. Further studies are needed to investigate the possible role of SDH deficiency in ACC pathogenesis.
Efficacy of Rhus coriaria (sumac) juice in reducing muscle pain during aerobic exercise
Authors: Alghadir AH , Gabr SA 
Published: August 2017

The main target of this study was to measure the influence of sumac juice drink on muscle indices and pain during an acute, intense exercise for 30 days. Forty healthy volunteers (15–25 years) were involved in aerobic exercise program for 4 weeks. Participants ingested sumac juice or placebo drink twice daily for 30 days. All participants were subjected for the evaluation of pain and estimation of serum: creatine kinase (CK), lactic acid dehydrogenase (LDH), troponin I, hydroxyproline (hyp), total antioxidant capacity (TAC), and in vitro antioxidant activity of sumac juice using pre-validated visual analog scale, colorimetric and immunoassays. The participants of both groups, placebo and sumac, showed an increment in pain scores both during exercise and post-exercise intervals. However, the sumac juice group showed a significant smaller increase in the pain scores compared to the placebo group. Participants in the sumac juice group were more willing to use the drink in the future. They achieved a higher satisfaction of sumac juice in ameliorating and the reduction of pain. Also, the sumac group showed a significant enhancement in the level of CK, LDH, troponin I, hyp, along with significant increase in serum (TAC) compared to the placebo group. The protective activity of muscle may relate to the antioxidant activity of phenolic component(s) in sumac juice as measured by 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging (87.9%) and β-carotene–linoleic acid (68.7%) assays. These data suggest that oral administration of sumac juice may have a beneficial effect on muscle performance among athletes.
