Characterization of Emergence of the Coulomb Blockade in a Pearl-Like DNA-AuNP Assembly

Due to its superior self-assembly properties and vast functionalization possibilities DNA has long been one of the most promising candidates for fabrication of nanoscale electrical components using molecular building blocks. There exist already many demonstrations on optical devices based on organizing metallic nanoparticles (NP) via DNAself-assembly, but despite the promises only few DNA based electrical devices or studies have been realized so far. Here we study the gold NP conjugated and metallized DNA TX-tilestructure, which we recently showed to exhibit the room temperature Coulomb blockade, the pre-requisition for a single electron transistor. The properties of the obtained Coulomb blockade are further characterized via the differential conductance measurements at temperatures ranging from 4.2 K to 10.2 K. The results show sharp blockade plateaus with varying threshold voltages, which yields further evidence of a gating effect by background charges. This strongly indicates that the DNA-NP assembly functions as a single electron transistor. Also, the additional growth of gold NPs and electrodes via chemical gold deposition process, needed to achieve the Coulomb blockade, is studied here in more details, yielding more insight to the process, and thus helping to realize better control of it.

Multiobjective Optimization of PID Controller of PMSM

PID controller is used in most of the current-speed closed-loop control of permanent magnet synchronous motors (PMSM) servo system. However, , , and of PID are difficult to tune due to the multiple objectives. In order to obtain the optimal PID parameters, we adopt a NSGA-II to optimize the PID parameters in this paper. According to the practical requirement, several objective functions are defined. NSGA-II can search the optimal parameters according to the objective functions with better robustness. This approach provides a more theoretical basis for the optimization of PID parameters than the aggregation function method. The simulation results indicate that the system is valid, and the NSGA-II can obtain the Pareto front of PID parameters.
ON THE IONIC Vs NEUTRAL NATURE OF METAL GUESTS IN THE THERMOELECTRIC CLATHRATE MATERIALS

Type I inorganic clathrates constitute some of the most promising nonoptimized structures discovered in the search for improved thermoelectric materials (TMs). The extent of charge transfer (CT) from the guest metal atoms to the semiconductor framework and the detailed nature of the host-guest interactions are both supposed to affect significantly each one of the three material properties “Seebeck coefficient, thermal and electrical conductivity” determining the figure of merit of TMs. Based on the distinction between charge donation “the flowing of electrons from the valence band of the guest sub-lattice to the conduction band of the framework sub-lattice” and charge transfer, the spatial displacement of electrons from the region of the metal guests sub-lattice to the region of the semiconductor frame, it was in the past concluded that the guest atoms are charge donors, but not ionic in these TMs. By using an ab-initio density functional approach and an atomic space partitioning based on quantum mechanics rather than on purely geometrical considerations, we show that the guest atoms (Sr, Ba) are indeed mostly ionic, regardless of the kind of cage they occupy. The insensitivity of CT to the cage size is confirmed by Diffraction Anomalous Fine Structure (DAFS) results across the Sr K edge. The significant displacement of the guest atom from the center of the 24-atom cage is found to be driven by the formation of strong frame-guest interactions also in the larger cage, a mechanism which eventually leads to similar CTs in the two kind of cages. The interplay between CT and thermo-power is investigated by using a one-electron transport model for the Seebeck coefficient evaluation and a number of model clathrates with varied CT, as induced by compression or expansion of the lattice.

Nonlinear Nonlocal Vibration of an Embedded Viscoelastic Y-SWCNT Conveying Viscous Fluid Under Magnetic Field Using Homotopy Analysis Method

In the present work, effect of von Karman geometric nonlinearity on the vibration characteristics of a Y-shaped single walled carbon nanotube (Y-SWCNT) conveying viscose fluid is investigated based on Euler Bernoulli beam (EBB) model. The Y-SWCNT is also subjected to a longitudinal magnetic field which produces Lorentz force in transverse direction. In order to consider the small scale effects, nonlocal elasticity theory is applied due to its simplicity and accuracy. The small-size effects and slip boundary conditions of nano-flow are taken into account through Knudsen number (Kn). The YSWCNT is surrounded by elastic medium which is simulated as nonlinear Visco-Pasternak foundation. Using energy method and Hamilton’s principle, the nonlinear governing motion equation is obtained. The governing motion equation is solved using both Galerkin procedure and Homotopy analysis method (HAM). Numerical results indicate the significant effects of the mass and velocity of the fluid flow, strength of longitudinally magnetic field, (Kn), angle between the centerline of carbon nanotube and the downstream elbows, nonlocal parameter and nonlinear Visco-Pasternak elastic medium. The results of this work is hoped to be of use in design and manufacturing of nano-devices in which Yshaped nanotubes act as basic elements. © 2014 IAU, Arak Branch.All rights reserved.
Links between sustainability-related innovation and sustainability management

This paper analyses the link between sustainability-related innovation and sustainability performance and the role that family firms play in this. This theme is particular relevant from a European point of view given the large number of firms that are family-owned. Governments often support environmentally and socially beneficial innovation with various policy instruments with the intention is to increase international competitiveness and simultaneously support sustainable development. In parallel, firms use corporate social responsibility (CSR) and environmental management systems partly in the hope that this will foster such innovation in their organisation. Hence the main research question of this paper is about the association of CSR and environmental management with environmentally and socially beneficial innovation and its determinants. Based on panel data, the paper analyses the link of corporate sustainability performance with sustainability innovation and the effect of being a family firm using panel estimation techniques. The paper discusses the results of the analysis, which point to a moderating role of family firms on the link of sustainability innovation and performance and assesses the policy implications of this insight.
How Wave-Wavelet Trading Wins and Beats the Market

The purpose of this paper is to showcase trading strategies that give solutions to three difficult and intriguing problems in business finance, economics and statistics. The paper discusses trading strategies for both commodities and stocks but the main focus is on stock market trading at the New York Stock Exchange. Problem 1: Buy Low and Sell High. The buy low and sell high problem can be summarized like this: suppose the price of a commodity or stock fluctuates indefinitely, is there any explicit strategy for a trader to "ride the price waves" by buying low and selling high to eventually win even if price does not increase? Problem 2: "Beat" the Market. In Part 2, the trading system presented in Part 1 is transformed into a strategy that always outperforms the market eventually. Problem 3: Can a Trader Outperform a geometric Brownian Motion? The general belief is that it is impossible to "beat" a GBM since technical analysis of historical prices is useless in predicting future prices. The last part of the paper shows that the answer to Problem 3 is actually a "YES", which is quite surprising. The trading strategies presented are based mainly on information obtained from the movements of waves and wavelets created by large and small fluctuations of market prices. They do not involve any forecasting or prediction of future prices. Behavioral economics also plays a role in the decision making process of the Wavelet Trading program.

On the number of shortest paths in Cartesian product graphs and its robustness

In this paper, we establish the maximum number of basic shortest paths in Cartesian product graphs and bounds on the maximum number of the vertex-disjoint shortest paths and on this of the edgedisjoint shortest paths. To the best of our knowledge, the class of Cartesian product graphs has been intensively studied according to various invariants, except the maximum number of (basic, vertex-disjoint or edge-disjoint) shortest paths, whereas the latter invariants were investigated for other graph classes. The main contribution of this paper is to fill this gap. Moreover, we investigate the impact of a vertex or an edge removal on the maximum number of basic shortest paths in Cartesian product graphs.
Forecasting the detectability of known radial velocity planets with the upcoming CHEOPS mission

The Characterizing Exoplanets Satellite (CHEOPS) mission is planned for launch next year with a major objective being to search for transits of known RV planets, particularly those orbiting bright stars. Since the radial velocity method is only sensitive to planetary mass, the radii, transit depths and transit signal-to-noise values of each RV planet are, a-priori, unknown. Using an empirically calibrated probabilistic mass-radius relation, forecaster (Chen & Kipping 2017a), we address this by predicting a catalog of homogeneous credible intervals for these three keys terms for 468 planets discovered via radial velocities. Of these, we find that the vast majority should be detectable with CHEOPS, including terrestrial bodies, if they have the correct geometric alignment. In particular, we predict that 22 mini-Neptunes and 82 Neptune-sized planets would be suitable for detection and that more than 80% of these will have apparent magnitude of V < 10, making them highly suitable for follow-up characterization work. Our work aims to assist the CHEOPS team in scheduling efforts and highlights the great value of quantifiable, statistically robust estimates for upcoming exoplanetary missions.
Terrorist Networks, Network Energy and Node Removal: A New Measure of Centrality Based on Laplacian Energy

In this work we propose a centrality measure for networks, which we refer to as Laplacian centrality, that provides a general framework for the centrality of a vertex based on the idea that the importance (or centrality) of a vertex is related to the ability of the network to respond to the deactivation or removal of that vertex from the network. In particular, the Laplacian centrality of a vertex is defined as the relative drop of Laplacian energy caused by the deactivation of this vertex. The Laplacian energy of network G with n vertices is defined as , where is the eigenvalue of the Laplacian matrix of G. Other dynamics based measures such as that of Masuda and Kori and PageRank compute the importance of a node by analyzing the way paths pass through a node while our measure captures this information as well as the way these paths are “redistributed” when the node is deleted. The validity and robustness of this new measure are illustrated on two different terrorist social network data sets and 84 networks in James Moody’s Add Health in school friendship nomination data, and is compared with other standard centrality measures.
Rapid communication The foveal 'crowding' effect: physics or physiology?

It has been known for some time that both foveal and peripheral visual acuity is higher for single letters than for letters in a row. Early work showed that this was due to the destructive interaction of adjacent contours (termed ‘crowding’ or contour interaction). It has been assumed to have a neural basis and a number of competing explanations have been advanced which implicate either high-level or low-level stages of visual processing. Our results suggest a much simpler explanation, one primarily determined by the physics of the stimulus rather than the physiology of the visual system. We show that, under conditions of contour interaction or ‘crowding’, the most relevant physical spatial frequency band of the letter is displaced to higher spatial frequencies and that foveal vision tracks this change in spatial scale. © 1999 Elsevier Science Ltd.

Improving intelligibility prediction under informational masking using an auditory saliency model

The reduction of speech intelligibility in noise is usually dominated by energetic masking (EM) and informational masking (IM). Most state-of-the-art objective intelligibility measures (OIM) estimate intelligibility by quantifying EM. Few measures model the effect of IM in detail. In this study, an auditory saliency model, which intends to measure the probability of the sources obtaining auditory attention in a bottom-up process, was integrated into an OIM for improving the performance of intelligibility prediction under IM. While EM is accounted for by the original OIM, IM is assumed to arise from the listener’s attention switching between the target and competing sounds existing in the auditory scene. The performance of the proposed method was evaluated along with three reference OIMs by comparing the model predictions to the listener word recognition rates, for different noise maskers, some of which introduce IM. The results shows that the predictive accuracy of the proposed method is as good as the best reported in the literature. The proposed method, however, provides a physiologically-plausible possibility for both IM and EM modelling.
A gut feeling about glucagon

Hyperglucagonaemia (in the fasting as well as in the postprandial state) is considered a core pathophysiological component of diabetes and is found to contribute substantially to the hyperglycaemic state of diabetes. Hyperglucagonaemia is usually viewed upon as a consequence of pancreatic alpha cell insensitivity to the glucagonsuppressive effects of glucose and insulin. Since we observed that the well-known hyperglucagonaemic response to oral glucose in patients with type 2 diabetes is exchanged by normal suppression of plasma glucagon levels following isoglycaemic intravenous glucose administration in these patients, we have been focusing on the gut and gut-derived factors as potential mediators of diabetic hyperglucagonaemia. In a series of clinical experiments, we have elucidated the role of gut-derived factors in diabetic hyperglucagonaemia and shown that glucose-dependent insulinotropic polypeptide promotes hyperglucagonaemia and that glucagon, hitherto considered a pancreas-specific hormone, may also be secreted from extrapancreatic tissues – most likely from proglucagon-producing enteroendocrine cells. Furthermore, our observation that fasting hyperglucagonaemia is unrelated to the diabetic state, but strongly correlates with obesity, liver fat content and circulating amino acids, has made us question the common ‘pancreacentric’ and ‘glucocentric’ understanding of hyperglucagonaemia and led to the hypothesis that steatosisinduced hepatic glucagon resistance (and reduced amino acid turnover) and compensatory glucagon secretion mediated by increased circulating amino acids constitute a complete endocrine feedback system: the liver–alpha cell axis. This article summarises the physiological regulation of glucagon secretion in humans and considers new findings suggesting that the liver and the gut play key roles in determining fasting and postabsorptive circulating glucagon levels.

The Impact of Imperfect Competition in Emission Permits Trading on Oligopolistic Electricity Markets

Abstract The impact and efficacy of a cap-and-trade regulation on the electric power industry depend on interactions of demand elasticity, transmission network, market structure, and strategic behavior of generation firms. This paper develops an equilibrium model of an oligopoly electricity market in conjunction with a Cap-and-Trade emissions permits market to study such interactions. The concept of conjectural variations is proposed to account for imperfect competition in the permits market. We demonstrate the model using a WECC 225-bus system with a detailed representation of the California market. In particular, we examine the extent to which permit trading strategies affect the market outcome. We find that a firm with more efficient technologies can employ strategic withholding of permits, which allows for its increase in output share in the electricity market at the expense of other less efficient firms.
Entrainement au contrôle inhibiteur et apprentissage en chimie dans le secondaire supérieur : Favoriser un changement de prévalence conceptuelle

L’apprentissage des modèles chimiques n’est pas simple d’autant plus que le passage du niveau macroscopique au niveau microscopique de la matière est compliqué par l’utilisation de représentations symboliques. Une habitude intuitive telle que « More A then more B » souvent utilisée chez les plus jeunes apprenants peut être abandonnée par les plus experts en chimie au profit de l’utilisation, parfois erronée, de modèles chimiques proposés lors du cursus scolaire. Dans le contexte de la dissolution d’un soluté dans un solvant, cette habitude est pourtant la stratégie de réponse efficace pour acquérir que le volume de solution est supérieur au volume de solvant et pouvoir ainsi calculer correctement la concentration en soluté (grandeur qui se rapporte au volume de solution). Notre recherche vise à améliorer l’apprentissage de ce concept, grandeur fondamentale en chimie. Nous avons élaboré un dispositif didactique expérimental basé sur l’utilisation d’outils permettant un conflit cognitif et un entrainement à la fonction exécutive de contrôle inhibiteur des conceptions non pertinentes dans le contexte de la dissolution d'un sel dans l’eau. L’objectif est de permettre une (ré)activation de la stratégie de réponse « More A then more B » afin de la rendre prévalente dans ce contexte. Cette étude confronte les scores obtenus par deux groupes d’élèves de grade 10 (15-17 ans) : l’un soumis à une activité de remédiation impliquant un conflit perceptocognitif seul et un autre groupe ayant réalisé cette même activité, mais suivie d’un entrainement à l’inhibition des conceptions non pertinentes dans le contexte de la dissolution d’un sel dans l’eau et du calcul d’une concentration. Les résultats obtenus montrent un impact positif du conflit cognitif suivi d’un apprentissage métacognitif à l’inhibition pour l’acquisition d’un concept de chimie pour des élèves du secondaire. Ils mettent également en évidence que des liens cognitifs privilégiés semblent exister lors du changement de prévalence conceptuelle.
THE ROLE OF THE CENTRAL BANK : THE ISRAELI CASE STANLEY FISCHER

The theory and practice of central banking has changed markedly in the past quarter century, in parallel with advances in macroeconomics that draw on the rational expectations approach and on game theory, and in response to the inflationary experiences of the 1970s and 1980s and the accumulation of evidence on the nature of the Phillips curve.1 These changes have already had a major impact on central banking in Israel. This lecture, in memory of Don Patinkin, mentor and friend of so many of us here this evening, presents an occasion for a systematic statement of the current approach to monetary policy and the role of the central bank in Israel, and some of the academic work and evidence on which it is based. In discussing modern central banking I shall take up: first, central bank independence; second, the inflation targeting approach to monetary policy; and third, the institutional arrangements most conducive to the success of the central bank. Of course, my discussion will relate to Israel and to changes proposed in the draft Bank of Israel law. I should note though that I will focus on monetary policy, and not on other aspects of the work of the Bank of Israel, including bank supervision and the role of the Governor as economic adviser to the government.
Optimism as a protective factor in child and adolescent depression

El estudio muestra que un estilo explicativo optimista consistente en explicar los acontecimientos positivos mediante atribuciones permanentes y globales y los negativos mediante atribuciones temporales y especificas se relaciona significativamente con menor sintomatologia depresiva. Se discuten las implicaciones de estos resultados a la luz del modelo reformulado de indefension aprendida (Abramson, Seligman y Teasdale, 1978) y la teoria de la desesperanza (Abramson, Metalsky y Alloy, 1989). Tambien se sugiere tener en cuenta nuevos conceptos como el de flexibilidad explicativa y otros factores que pueden influir, como la autoestima, la percepcion de controlabilidad sobre las situaciones estresantes o el grado de importancia otorgado a las mismas. Las chicas presentan un estilo explicativo mas optimista en la preadolescencia y los ninos mayores presentan puntuaciones en depresion mas elevadas.
