description: For any metric space $X$ endowed with the action of a group $G$, and two $n$-gons $\vec x=(x_1,\dots,x_n)\in X^n$ and $\vec y=(y_1,\dots,y_n)\in X^n$ in $X$, we introduce the $G$-deviation $d(G\vec x,\vec y\,)$ of $\vec x$ from $\vec y$ as the distance in $X^n$ from $\vec y$ to the $G$-orbit $G\vec x$ of $\vec x$ in the $n$-th power $X^n$ of $X$. For some groups $G$ of affine transformations of the complex plane, we deduce simple-to-apply formulas for calculating the $G$-derviation between $n$-gons on the complex plane. We apply these formulas for defining new measures of asymmetry of triangles. These new measures can be applied in Electric Power Engineering for evaluating the quality of 3-phase electric power. One of such measures, namely the affine deviation, is espressible via the unbalance degree, which is a standard characteristic of quality of three-phase electric power.

description: Modeling and predicting extreme movements in GDP is notoriously difficult, and the selection of appropriate covariates and/or possible forms of nonlinearities are key in obtaining precise forecasts. In this paper, our focus is on using large datasets in quantile regression models to forecast the conditional distribution of US GDP growth. To capture possible nonlinearities, we include several nonlinear specifications. The resulting models will be huge dimensional, and we thus rely on a set of shrinkage priors. Since Markov chain Monte Carlo estimation becomes slow in these dimensions, we rely on fast variational Bayes approximations to the posterior distribution of the coefficients and the latent states. We find that our proposed set of models produces precise forecasts. These gains are especially pronounced in the tails. Using Gaussian processes to approximate the nonlinear component of the model further improves the good performance, in particular in the right tail.

The deflection angle in the strong field limit is calculated and various lens parameters of two wormholes are compared. It is shown that the JNW wormhole exhibits the relativistic images, while the Ellis wormhole does not have any relativistic images due to the absence of its photon sphere.

description: Report Introduction: AMS promotes farmers markets and direct marketing of farm products. AMS recognized that some individuals participating in FMNP were not redeeming all of their checks and wanted to determine ways of raising the redemption rates. Southeastern PA RC&D and AMS started the Transportation—Connecting Local Farmers with USDA Farmers Market Nutrition Program Participants project in September 2005 to determine whether lack of transportation was a major reason for some low-income individuals not redeeming their FMNP checks. The project was to test the concept that providing transportation to FMNP participants and other low-income individuals made sense, was economical, and increased redemption rates, thereby increasing farmer income. To determine the answers to these study objectives, AMS provided financial and technical assistance to the Southeastern PA RC&D. The results of the study will provide additional information to farmers, farmers market operators, nutrition professionals, and those involved with FMNP.

The low-energy spectrum of (2,0) theory on T^5 x R
Creators: name: Henningson, Mans
Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We consider the ADE-series of (2, 0) supersymmetric quantum theories on T^5 \times R, where the first factor is a flat spatial five-torus, and the second factor denotes time. The quantum states of such a theory Φare characterized by a discrete quantum number f \in H^3 (T^5, C), where the finite abelian group C is the center subgroup of the corresponding simply connected simply laced Lie group G. At energies that are low compared to the inverse size of the T^5, the spectrum consists of a set of continua of states, each of which is characterized by the value of f and some number 5r of additional continuous parameters. By exploiting the interpretation of this theory as the ultraviolet completion of maximally supersymmetric Yang-Mills theory on T^4 \times S^1 \times R with gauge group G_{adj} = G/C and coupling constant g given by the square root of the radius of the S^1 factor, one may compute the number N_f^r (Φ) of such continua. We perform these calculations in detail for the A- and D-series. While the Yang-Mills theory formalism is manifestly invariant under the \SL_4 (Z) mapping class group of T^4, the results are actually found to be invariant under the \SL_5 (Z) mapping class group of T^5, which provides a strong consistency check.

Abstract - Recent trends in power electronics are driving the need to revisit design tools and capabilities. Wide bandgap technologies have been demonstrated to hold great promise for achieving higher efficiencies, increased volumetric density, and provide system level cost benefits relating to thermal management. However, the faster switching devices and circuits tend to generate more EMI that can disrupt surrounding components, not to mention adversely impacting their own controls to such a degree that failures can be induced.

description: In this article we study an optimal stopping/optimal control problem which models the decision facing a risk-averse agent over when to sell an asset. The market is incomplete so that the asset exposure cannot be hedged. In addition to the decision over when to sell, the agent has to choose a control strategy which corresponds to a feasible wealth process. We formulate this problem as one involving the choice of a stopping time and a martingale. We conjecture the form of the solution and verify that the candidate solution is equal to the value function. The interesting features of the solution are that it is available in a very explicit form, that for some parameter values the optimal strategy is more sophisticated than might originally be expected, and that although the setup is based on continuous diffusions, the optimal martingale may involve a jump process. One interpretation of the solution is that it is optimal for the risk-averse agent to gamble.

description: The bound state extension of Skyrme's topological soliton model for the heavy baryons is quantized canonically in arbitrary reducible representations of the SU(3) flavor group. The canonical quantization leads to an additional negative mass term, which stabilizes the quantized soliton solution. The heavy flavor meson in the field of the soliton is treated with semiclassical quantization. The representation dependence of the calculated spectra for the strange, charm and bottom baryons is explored and compared to the extant empirical spectra.

description: The problem of vortex pair motion in two-dimensional plane radial flow is solved. Under certain conditions for flow parameters, the vortex pair can reverse its motion within a bounded region. The vortex-pair translational velocity decreases or increases after passing through the source/sink region, depending on whether the flow is diverging or converging, respectively. The rotational motion of two corotating vortexes in a quiescent environment transforms into motion along a logarithmic spiral in the presence of radial flow. The problem may have applications in astrophysics and geophysics.

description: Hot Jupiters are very good targets for transmission spectroscopy analysis. Their atmospheres have a large scale height implying a high signal to noise ratio. As these planets orbit close to their stars, they often present strong thermal and chemical hetereogeneities between the day and the night side of their atmosphere. For the hottest ones, the thermal dissociation of several species occurs in their atmospheres which leads to a stronger chemical dichotomy between the two hemispheres. It has already been shown that the current retrieval algorithms, which are using 1D forward models, find biased molecular abundances in ultra hot Jupiters. Here, we quantify the effective temperature domain over which these biases are present. We use a set of 12 simulations of typical Hot Jupiters from Teq = 1000 K to Teq = 2100 K performed with the Substellar and Planetary Atmospheric Radiation and Circulation global climate model and generate transmission spectra that fully account for the 3D structure of the atmosphere with Pytmosph3R. These spectra are then analyzed using the 1D TauREx retrieval code. We find that for JWST-like data, accounting for non-isothermal vertical temperature profiles is required over the whole temperature range. We further find that 1D retrieval codes start to estimate wrong parameter values for planets with equilibrium temperatures greater than 1400 K if there are absorbers in the visible able to create a hot stratosphere. The high temperatures at low pressures indeed entail a thermal dissociation of species which creates a strong chemical day-night dichotomy. As a by-product, we demonstrate that when using synthetic observations to assess the detectability of a given feature or process using a Bayesian framework, it is valid to use non-randomized input data, as long as the anticipated observational uncertainties are correctly taken into account.

They affect the tracks in the HR diagram, the lifetimes, the surface abundances, the hardness of the radiation field, the chemical yields, the presupernova status, the nature of the remnant, the mechanical energy released in the interstellar medium, etc... In this paper, after recalling a few characteristics of mass loss and rotation, we review the effects of these two processes at different metallicities. Rotation probably has its most important effects at low metallicities, while mass loss and rotation deeply affect the evolution of massive stars at solar and higher than solar metallicities.

Abstract � Gallium Nitride and Silicon Carbide are two representative materials for the third generation wide bandgap semiconductor. Gallium Nitride power transistors have higher electron mobility than SiC, making them superior devices for high frequency and efficient switching. The lateral HEMT device structure is also a more suitable topology for power integration together with driver and control blocks to achieve a ultra-high power density module and system. This presentation will discuss an accurate and comprehensive evaluation of GaN switching characteristics. The effects of gate driver topologies, gate resistors and deadtime will be explored. Several different applications of high frequency GaN based power conversion will be illustrated.

A Generative Node-attribute Network Model for Detecting Generalized Structure

description: Exploring meaningful structural regularities embedded in networks is a key to understanding and analyzing the structure and function of a network. The node-attribute information can help improve such understanding and analysis. However, most of the existing methods focus on detecting traditional communities, i.e., groupings of nodes with dense internal connections and sparse external ones. In this paper, based on the connectivity behavior of nodes and homogeneity of attributes, we propose a principle model (named GNAN), which can generate both topology information and attribute information. The new model can detect not only community structure, but also a range of other types of structure in networks, such as bipartite structure, core-periphery structure, and their mixture structure, which are collectively referred to as generalized structure. The proposed model that combines topological information and node-attribute information can detect communities more accurately than the model that only uses topology information. The dependency between attributes and communities can be automatically learned by our model and thus we can ignore the attributes that do not contain useful information. The model parameters are inferred by using the expectation-maximization algorithm. And a case study is provided to show the ability of our model in the semantic interpretability of communities. Experiments on both synthetic and real-world networks show that the new model is competitive with other state-of-the-art models.

Abstract: Gate drive is the key to maximize the switching performance of power devices, in the meantime, it could be utilized to monitor and protect devices for efficient and reliable converter operation. For emerging SiC devices, a good gate drive design could be a critical differentiator to fully utilize its value in actual converters. This webinar focuses on SiC based gate drive technology. It starts with the introduction of gate drive basics along with design challenges and opportunities for SiC devices. Then advanced gate drive techniques will be highlighted for smartly driving, online monitoring, and fast response protection of highspeed switching SiC devices. Several examples will be illustrated to demonstrate the effectiveness of the intelligent gate drive on the performance improvement at both device level and converter level.
The Effectiveness of three preoperative learning programs on patient recovery and learning
Creators: name: Cranstoun, Catherine Jean
Publisher: name: University of British Columbia
Year: 2010

description: The study reported here was a controlled experiment in which three groups of eleven randomly assigned female patients undergoing cholecystectomy were studied for the effectiveness of three different types of preoperative learning programs: 1. a systematic, planned learning program in which learning objectives, strategies and tests were designed to meet individual patient preoperative learning needs; 2. a planned group learning program which involved a class of patients and discussion of a slide-sound presentation and demonstration of exercises; and 3. an unplanned learning program in which patients experienced only incidental learning objectives. Since previous research had not controlled for type of surgery, the major question in this study was whether or not the effectiveness of preoperative learning programs as measured by postoperative recovery measures would be a persistent finding in a more rigidly controlled study. In addition to testing for cognitive achievement in all three learning groups, a variety of physiological measurements of postoperative recovery were made and studied in relation to cognitive achievement. The study also asked patients to validate a series of 50 preoperative learning needs and collected data about their cognitive learning styles in a postoperative patient questionnaire. Contrary to previous research, it was found that the traditional physiological measurements of postoperative recovery used to measure the effectiveness of preoperative learning programs could not be construed as valid, direct measurements of learning. When studied in relation to cognitive achievement scores, these measures did not correlate significantly. Thus, it was concluded that the measures are not valid, indirect measures of effective preoperative learning. There was however, a suggestive finding that the use of analgesic drugs may be a useful indirect measure of effective preoperative learning. There were no significant differences in cognitive achievement among the three groups, but there was a significant difference between the Individualized and the Incidental Learning Group in relation to the number of doses of parenteral drugs administered. Anaesthetic time also correlated negatively and significantly with the cognitive achievement score and there were significant differences between all three learning groups in relation to anaesthetic time. This latter finding is of value in providing appropriate reinforcement of learning postoperatively. It may be that patients that have a long anaesthetic time will need more reinforcement of learning postoperatively.

description: Throughout a typical Earth orbit a satellite is constantly bombarded by radiation with trapped and solar protons being of particular concern as they gradually damage the focal plane devices throughout the mission and degrade their performance. To understand the impact the damage has on CCDs and how it varies with their thermal history a proton radiation campaign has been carried out using a CCD280. The CCD is irradiated at 153 K and gradually warmed to 188 K in 5 K increments with Fe55 X-ray, dark current and trap pumping images taken at 153 K after each anneal step. The results show that despite the trap landscape changing throughout the anneal it has little impact on parallel charge transfer inefficiency. This is thought to be because most traps are unaffected and a lot of those that do anneal only move from the continuum between distinct trap species and into a nearby divacancy trap 'peak' whose emission time constant is similar enough to still impact the CTI. In terms of using a CCD280 or similar devices in a mission the CTI being unaffected by thermal annealing up to 188 K means that any CTI correction needed as the radiation damage builds up does not have to take into account the thermal history of the focal plane. However, it is possible that a significant amount of annealing will occur at temperatures greater than 188 K and care should be taken when a mission is operating in this range to gather accurate pre-flight data.

To inspect and calibrate residual systematic errors in recovered temperature maps is important as most previous studies of cosmology are based on these maps. By analyzing pixel-ring couping and latitude dependence of CMB temperatures, we find notable systematic deviation from CMB Gaussianity in released Wilkinson Microwave Anisotropy Probe (WMAP) maps. The detected deviation is hard to explain by any process in the early universe and can not be ignored for a precision cosmology study.

description: Report Executive Summary: Until recently, local and regional food system development efforts have emphasized small scale direct marketing activities, while food freight transportation policy and planning have primarily focused on distribution infrastructure for large-scale commodity products. As the demand for local food continues to increase, innovative and scale-appropriate infrastructure and expertise are needed to respond to the market pull. The U.S. Department of Agriculture (USDA) identified a need to direct applied research resources to focus on transportation and distribution issues in order to facilitate effective growth in local and regional food systems. Through collaboration between USDA’s Agricultural Marketing Service (AMS) and the University of Wisconsin-Madison Center for Integrated Agricultural Systems (CIAS) a new approach emerged. The USDA and CIAS researchers saw a great need for providing an opportunity for networking and sharing of perspectives among the diverse groups of regional food suppliers and the established freight transportation providers. The collaboration led to the Networking Across the Supply Chain (NASC) conference that served as the venue to accomplish the objectives of fostering information exchange, networking, and collaboration between the participants of the food supply chain. This report presents the conference overview with its key themes and findings as well as emergent strategies and innovative solutions to help bring regional food to regional markets.

description: We consider cosmological perturbations caused by modulated inflaton velocity. During inflation, the inflaton motion is damped and the velocity is determined by the parameters such as couplings or masses that may depend on light fields(moduli). The number of e-foldings is different in different patches if there are spatial fluctuations of such parameters. Based on this simple idea, we consider ``modulated inflation'' in which the curvature perturbation is generated by the fluctuation of the inflaton velocity. This talk is based on our recent papers.

description: This paper extends the monadic electron framework to incorporate the Higgs mechanism, reinterpreting mass generation as a topological interaction between a single cosmic worldline and the Higgs field. We propose that particle masses arise from knot invariants (crossing number, Jones polynomial) of the worldline's configuration. The Higgs vacuum expectation value (VEV) stabilizes these knots via spontaneous symmetry breaking (SSB), explaining the lepton/quark mass hierarchy. Experimental signatures include fixed mass-ratio resonances, topological phase transitions at ~10 TeV, and Higgs decay anomalies.

By embedding the Standard Model's Higgs mechanism within a topological quantum field theory (TQFT), this work bridges geometric intuition with quantum field theory, transforming abstract quantum numbers into spacetime-resilient structures.

In recent years, the automotive and aerospace industries have brought stringent reliability constraints on power electronic converters because of safety requirements. Today customers of many power electronic products expect up to 20 years of lifetime and they also want to have a failure free period and all with focus on the financials. The renewable energy sectors are also following the same trend, and more and more efforts are being devoted to improving power electronic converters to account for reliability with cost effective and sustainable solutions. This presentation will introduce the recent progress in the reliability aspect study of power electronic converters for power electronic applications with special focus on renewables. It will cover the following contents: the motivations for highly reliable electric energy conversion in renewable energy systems, the reliability requirements of typical renewable energy systems and its implication on the power electronic converters, failure mechanisms and lifetime models of key power electronic components (e.g., power semiconductor switches, capacitors, and fans), long-term mission profiles in Photovoltaic (PV) and wind power applications and the component level stress analysis, reliability analysis methods, tools, and improvement strategies of power electronic converters for renewable energy systems. A few case studies on PV and wind power based renewable energy systems will also be discussed.

description: The systematics of the giant dipole resonance (GDR) widths in hot and rotating nuclei are studied in terms of temperature T, angular momentum J and mass A. The different experimental data in the temperature range of 1 - 2 MeV have been compared with the thermal shape fluctuation model (TSFM) in the liquid drop formalism using a modified approach to estimate the average values of T, J and A in the decay of the compound nucleus. The values of the ground state GDR widths have been extracted from the TSFM parametrization in the liquid drop limit for the corrected T, J and A for a given system and compared with the corresponding available systematics of the experimentally measured ground state GDR widths for a range of nuclei from A = 45 to 194. Amazingly, the nature of the theoretically extracted ground state GDR widths matches remarkably well, though 1.5 times smaller, with the experimentally measured ground state GDR widths consistently over a wide range of nuclei.

2018 PES GM Panel Presentation
Most professional societies, including the IEEE and societies within the IEEE, have student programs. These programs often include discounted student membership fees, student chapters and organizations, and specific activities tailored toward student members. This panel session brings together leaders of student programs from various societies. Specifically, the panelists will discuss their current efforts, lessons learned from past experiences, successes and challenges regarding their student programs. The objective of this panel session is to educate the IEEE PES community on student programs and for the panelists to learn from each other and improve student programs within their respective societies.

description: Atomic scale computer simulations on structures and photo induced volume changes of flatly and obliquely deposited amorphous selenium films have been carried out in order to understand how the properties of chalcogenide glasses are influenced by their preparation method. Obliquely deposited a-Se thin films contain more coordination defects, larger voids than the flatly deposited ones. To model the photo induced volume changes the electron excitation and hole creation were treated independently within the framework of tight-binding formalism. Covalent and interchain bond breakings and formations were found. The obliquely deposited samples containing voids showed a wide spectrum of photo induced structural changes in microscopic and volume changes in macroscopic levels.

description: The electronic shell structure of triangular, hexagonal and round graphene quantum dots (flakes) near the Fermi level has been studied using a tight-binding method. The results show that close to the Fermi level the shell structure of a triangular flake is that of free massless particles, and that triangles with an armchair edge show an additional sequence of levels ("ghost states"). These levels result from the graphene band structure and the plane wave solution of the wave equation, and they are absent for triangles with an zigzag edge. All zigzag triangles exhibit a prominent edge state at the Fermi level, and few low-energy conduction electron states occur both in triangular and hexagonal flakes due to symmetry reasons. Armchair triangles can be used as building blocks for other types of flakes that support the ghost states. Edge roughness has only a small effect on the level structure of the triangular flakes, but the effect is considerably enhanced in the other types of flakes. In round flakes, the states near the Fermi level depend strongly on the flake radius, and they are always localized on the zigzag parts of the edge.
Heat conduction in the disordered Fermi-Pasta-Ulam chain

description: We address the question of the effect of disorder on heat conduction in an anharmonic chain with interactions given by the Fermi-Pasta-Ulam (FPU) potential. In contrast to the conclusions of an earlier paper [Phys. Rev. Lett. 86, 63 (2001)] which found that disorder could induce a finite thermal conductivity at low temperatures, we find no evidence of a finite temperature transition in conducting properties. Instead, we find that at low temperatures, small system size transport properties are dominated by disorder but the asymptotic system size dependence of current is given by the usual FPU result J ~ 1/N^{2/3}. We also present new interesting results on the binary-mass ordered FPU chain.

Correlated diffusion of membrane proteins and their effect on membrane viscosity

description: We extend the Saffman theory of membrane hydrodynamics to account for the correlated motion of membrane proteins, along with the effect of protein concentration on that correlation and on the response of the membrane to stresses. Expressions for the coupling diffusion coefficients of protein pairs and their concentration dependence are derived in the limit of small protein size relative to the inter-protein separation. The additional role of membrane viscosity as determining the characteristic length scale for membrane response leads to unusual concentration effects at large separation -- the transverse coupling increases with protein concentration, whereas the longitudinal one becomes concentration-independent.

A Non-Supersymmetric Large-N 3D CFT And Its Gravity Dual

description: We propose a three dimensional non-supersymmetric theory that is conformal in the large N limit. In a certain well defined bosonic sub-sector of gauge invariant operators, this theory is planar equivalent to the theory recently proposed by Aharony, Bergman, Jafferis and Maldacena as the theory on multiple M2 branes at an orbifold singularity. We discuss the realization of the theory on a brane configuration of type 0B string theory. Moreover, we propose an 11D gravity dual, obtained by a projection of M-theory on AdS4 x S7 / Z_k.

description: Résumé. Musiciennes de terre cuite du sanctuaire de Fontana Calda (Sicile). Dans les années 50 on a mis au jour dans le sanctuaire de Fontana Calda (Sicile centrale) un dépôt constitué de centaines de figurines de joueurs d’aulos, de tympanon, de cymbales, de harpe, ainsi que des groupes de joueurs d’aulos et de tympanon ; elles datent d’entre la fin du VIe s. et le début du IIIe s. Des figurines comparables ont été retrouvées sur de nombreux autres sites de Sicile et en particulier dans des sanctuaires qui étaient comme celui de Fontana Calda consacrés à des divinités chthoniennes. Ces figurines semblent renvoyer à des cérémonies dont les protagonistes étaient exclusivement des femmes : les instruments de musique pourraient évoquer des moments précis du mythe et de la quête de Déméter à la recherche de sa fille Korè enlevée par Hadès. Les musiciennes de Fontana Calda donnent une image variée de la musique qui accompagnait tous les instants du rituel.

Abstract. In the Sanctuary of the Fontana Calda in Butera (central-south Sicily) was brought to light a sacred deposit. The discovery, made in the 1950s, revealed, among many other things, hundreds of single statuettes of aulos, tympanon, kymbala, and harp players, and groups of aulos and tympanon players. They can be dated between the end of the 6th c. and the beginning of the 3rd c. B.C. Many other places in Sicily have yielded these particular types, especially sanctuaries like Fontana Calda that were dedicated to “chthonic” divinities. The representations seem to refer to ceremonies where the protagonists were exclusively women, with the musical instruments perhaps evoking exact episodes of myth and the sorrowful search by the mother of Kore, who had been abducted by Hades. Music was the background in every moment of the sacred ritual of which the female musicians of Fontana Calda offer a rich and singular repertory.

Signal-to-noise ratio of Gaussian-state ghost imaging

description: The signal-to-noise ratios (SNRs) of three Gaussian-state ghost imaging configurations--distinguished by the nature of their light sources--are derived. Two use classical-state light, specifically a joint signal-reference field state that has either the maximum phase-insensitive or the maximum phase-sensitive cross correlation consistent with having a proper $P$ representation. The third uses nonclassical light, in particular an entangled signal-reference field state with the maximum phase-sensitive cross correlation permitted by quantum mechanics. Analytic SNR expressions are developed for the near-field and far-field regimes, within which simple asymptotic approximations are presented for low-brightness and high-brightness sources. A high-brightness thermal-state (classical phase-insensitive state) source will typically achieve a higher SNR than a biphoton-state (low-brightness, low-flux limit of the entangled-state) source, when all other system parameters are equal for the two systems. With high efficiency photon-number resolving detectors, a low-brightness, high-flux entangled-state source may achieve a higher SNR than that obtained with a high-brightness thermal-state source.

2018 PES GM Panel Presentation
The physical power system increasingly relies on the cyber system for monitoring, control and optimal operation.  Therefore, the reliable operation of the power system is highly dependent on the reliability of the associated cyber system.  Risk analysis, reliability evaluation, and stability control of power systems should therefore incorporate the impact of the cyber system.  How to model the cyber-physical power system (CPPS) becomes the first and the most critical step in studying this system.  The integrated cyber-physical power system is complex, featuring a mixture of discrete events and continuous processes.  Currently, there is no comprehensive methodological basis for the modeling of CPPS, but novel approaches are emerging.  This panel will discuss the challenges involved in modelling of CPPS and the latest research achievements in this area.  The panelists will share their experiences in modelling various cyber-physical sub-systems in power grid and how they apply the models for various analysis.
