An integrated-optic current sensor for relaying and metering in high-voltage power systems
Creators: name: Bull, Jeffrey David
Publisher: name: University of British Columbia
Year: 2009

description: Optical instrumentation has attracted considerable interest over the years for high-voltage applications. Optical fibers, by virtue of their all dielectric construction, are highly resistant to electrical breakdown and electro-magnetic interference, making them ideally suited for signal transmission in substation environments. A novel hybrid current sensor for high-voltage instrumentation is developed, constructed, and tested here using a Rogowski coil and an integrated-optic Pockels cell (IOPC). The Rogowski coil generates a low-level voltage signal in proportion to the derivative of the primary current. A fully passive integrator is constructed from ultrastable components, permitting integration in the high-voltage environment without the compromised reliability associated with active components and their power supplies. A key aspect of this work is placing the integrator before the optical path to avoid amplification of low-frequency noise and drift. The penalty for using the passive integrator is high attenuation, necessitating a high sensitivity IOPC. High sensitivity IOPCs with integrated electrodes are fabricated on both Xcut and Y-cut lithium niobate substrates using titanium indiffusion. Only the X-cut configurations are able to provide the needed phase and magnitude stability because they can be fabricated without an optical buffer layer. The buffer layer is shown to be problematic due to mobile charge. IOPCs are pigtailed and packaged in an ultralow stress configuration to provide thermal stability. High current testing shows the hybrid sensor to exceed IEEE and IEC linearity standards for 0.3 and 0.2 % metering accuracy at a nominal current of 3 kA. The same sensor is also shown to achieve better than 0.5 % instantaneous accuracy when measuring transient over-currents up to 30 kA. The thermal stability of the sensor is shown to be capable of achieving 0.3 % accuracy over a temperature range from —30 to +70° C. Some of the IOPCs tested in this work exhibit a significant degree of mode conversion. The mode conversion is not intentional and results in distortion of the IOPC transfer function from its ideal sinusoidal shape. The mechanisms responsible for the mode conversion are explained by a coupled-mode formulation of the IOPC that takes into account the anisotropy caused by the electro-optic effect as well as the intrinsic anisotropy of lithium niobate. It is shown that deviations on the order of 0.5° of the propagation direction with respect to the crystallographic axes can induce 100 % mode conversion with waveguide lengths of a few centimeters. The importance of crystallographic alignment is identified and a solution to suppress mode conversion by maintaining a minimum amount of modal birefringence is proposed. Lastly, a new method for measuring birefringence is described based on mode conversion analysis. The method takes advantage of parasitic mode conversion and is non-destructive and unambiguous.

description: Due to the complexity of general and partial equilibrium models, conventional sensitivity analysis, qualitative reviews or literature-based meta-analyses do not allow for detailed assessments of the role of individual parameters and policy shocks across different models. Therefore, the partial equilibrium model “GSIM” and a single country CGE are employed to generate synthetic scenarios based on randomly specified combinations of base data, elasticities and tariff changes selected from previously specified, plausible ranges. The synthetic meta-data has the advantage that the values of explanatory variables are measured exactly. This makes it possible to explore complex issues of functional form and interaction between variables in the estimation of the response surface of each model as well as for a joint response surface of both models. The results indicate that firstand second-order polynomials provide sufficient approximations of the model responses, and especially for the CGE model, interaction terms of elasticities with policy variables play an important role. Furthermore, simultaneous estimation of a response surface of scenarios from both models proves to be feasible and enables quantitative comparisons of different model output, e.g. welfare measures.

description: The paper looks at a hypothetical area yield insurance at the level of Farm Accountancy Data Network (FADN) regions: Regional Yield Insurance (RYI). Total premium cost is evaluated for each MS and EU-27 assuming that the whole crop surface for each single arable crop is insured. In order to check the efficiency of RYI for smoothing the farmers’ income, we calculate the farmers’ yield variability from a sample of individual farm FADN income data for two scenarios. The first scenario is the current one without RYI, and the second one is with RYI under the hypothesis of 100% market penetration. These analyses enable us to evaluate the potential of RYI as a farmers’ income stabilizer. Moreover, they provide an insight of the potential of other kinds of index products in the heterogeneous European landscape. Results show that the risk reduction capacity of RYI is not very high for the case analyzed (wheat). However, there are some exceptions where the risk can be significantly reduced.

description: Linear quadratic graphon field games (LQ-GFGs) are defined to be LQ games which involve a large number of agents that are weakly coupled via a weighted undirected graph on which each node represents an agent. The links of the graph correspond to couplings between the agents' dynamics, as well as between the individual cost functions, which each agent attempts to minimize. We formulate limit LQ-GFG problems based on the assumption that these graphs lie in a sequence which converges to a limit graphon. First, under a finite-rank assumption on the limit graphon, the existence and uniqueness of solutions to the formulated limit LQ-GFG problem is established. Second, based upon the solutions to the limit LQ-GFG problem, epsilon-Nash equilibria are constructed for the corresponding game problems with a very large but finite number of players. This result is then generalized to the case with random initial conditions. It is to be noted that LQ-GFG problems are distinct from the class of graphon mean field game (GMFG) problems where a population is hypothesized to be associated with each node of the graph [Caines and Huang CDC 2018, 2019].

The cephalic part of the prosoma is elevated and rounded on all sides. The thoracic part is lower than the cephalic, the highest point being the centre (Figure 2A–D). Opisthosoma oval, slightly longer than wide, with no clear constriction (Figure 2A–D). Opisthosoma dorsally sclerotized, venter softer. Chelicerae are almost the length of the carapace, lateral sides almost parallel; distal half is a bit wider than the proximal half (Figure 2A–D). Chelicerae dentition not examined. Leg formula 4132. Leg spination not examined. Palps as in Figure 3A–D. Female remains unknown.   Distribution

description: The correlation between charge and spin orderings in hole-doped antiferromagnets is studied within an effective model of quantum strings fluctuating in an antiferromagnetic background. In particular, we perform the direct estimation of the charge and spin long-range-order parameters by means of the quantum Monte Carlo simulation. A hidden spin long-range order is found to be governed by a competition between the two trends caused by increasing hole mobility: the enhancement of the two-dimensional spin-spin correlation mediated by hole motions and the reformation of a strong stripe order.

Impact of Microlensing on Observational Strategies for Gravitational Time Delay Measurements

description: Microlensing not only brings extra magnification lightcurves on top of the intrinsic ones but also shifts them in time domain, making the actual time-delays between images of strongly lensed active galactic nucleus change on the $\sim$ day(s) light-crossing time scale of the emission region. The microlensing-induced time-delays would bias strong lens time-delay cosmography if uncounted. However, due to the uncertainties of the disk size and the disk model, the impact is hard to accurately estimate. In this work, we study how to reduce the bias with designed observation strategy based on a standard disk model. We find long time monitoring of the images could alleviate the impact since it averages the microlensing time-lag maps due to the peculia motion of the source relative to the lens galaxy. In addition, images in bluer bands correspond to smaller disk sizes and therefore benefit time-delay measurements as well. We conduct a simulation based on a PG 1115+080-like lensed quasar. The results show the time-delay dispersions caused by microlensing can be reduced by $\sim40\%$ with 20-year lightcurves while u band relative to r band reduces $\sim75\%$ of the dispersions. Nevertheless, such an effect can not be totally eliminated in any cases. Further studies are still needed to appropriately incorporate it in inferring an accurate Hubble constant.

description: We consider the role of magnetic fields on the broken inversion superconductor CePt_3Si. We show that upper critical field for a field along the c-axis exhibits a much weaker paramagnetic effect than for a field applied perpendicular to the c-axis. The in-plane paramagnetic effect is strongly reduced by the appearance of helical structure in the order parameter. We find that to get good agreement between theory and recent experimental measurements of H_{c2}, this helical structure is required. We propose a Josephson junction experiment that can be used to detect this helical order. In particular, we predict that Josephson current will exhibit a magnetic interference pattern for a magnetic field applied perpendicular to the junction normal. We also discuss unusual magnetic effects associated with the helical order.

The organization researched was the IAPAR - Agronomic Institute of Paraná, the entity responsible for generating and adopting new technologies seeking improvement in the state's agro-production process. The results obtained enable for reflections which may come to contribute to the discussions over the theme: a large part of the women-researchers do not believe that the gender question is relevant in the scientific environment; however, they do sense the prejudice from their counterparts during the performance of their daily activities besides realizing that men-scientists occupy the key-positions in the world of science. The collected data also show that the switch from this scenario to a more democratic one, contemplating both men and women in a more equal manner, is gradually taking place.

description: Structural degeneracies underpin the ferroic behavior of next-generation two-dimensional materials, and lead to peculiar two-dimensional structural transformations under external fields, charge doping and/or temperature. The most direct indicator of the ease of these transformations is an {\em elastic energy barrier}, defined as the energy difference between the (degenerate) structural ground state unit cell, and a unit cell with an increased structural symmetry. Proximity of a two-dimensional material to a bulk substrate can affect the magnitude of the critical fields and/or temperature at which these transformations occur, with the first effect being a relative charge transfer, which could trigger a structural quantum phase transition. With this physical picture in mind, we report the effect of modest charge doping (within $-0.2$ and $+0.2$ electrons per unit cell) on the elastic energy barrier of ferroelastic black phosphorene and nine ferroelectric monochalcogenide monolayers. The elastic energy barrier $J_s$ is the energy needed to create a $Pnm2_1\to P4/nmm$ two-dimensional structural transformation. Similar to the effect on the elastic energy barrier of ferroelastic SnO monolayers, group-IV monochalcogenide monolayers show a tunable elastic energy barrier for similar amounts of doping: a decrease (increase) of $J_s$ can be engineered under a modest hole (electron) doping of no more than one tenth of an electron or a hole per atom.

description: We report a numerical simulation for the phase diagram of a simple two dimensional model, similar to one proposed by Noro and Frenkel [J. Chem. Phys. \textbf{114}, 2477 (2001)] for membrane proteins, but one that includes the role of the solvent. We first use Gibbs ensemble Monte Caro simulations to determine the phase behavior of particles interacting via a square-well potential in two dimensions for various values of the interaction range. A phenomenological model for the solute-solvent interactions is then studied to understand how the fluid-fluid coexistence curve is modified by solute-solvent interactions. It is shown that such a model can yield systems with liquid-liquid phase separation curves that have both upper and lower critical points, as well as closed loop phase diagrams, as is the case with the corresponding three dimensional model.

description: Purpose: Pain is a common symptom following proximal femoral fractures (PFF), however, information on its treatment in terms of agents and type of use (scheduled vs. pro re nata [PRN]) is scarce. The main objective of this study was to examine pain medication regimens according to pain intensity following PFF. Furthermore, we explored the utilization of medication plans. Methods: The “ProFem”-study on healthcare provision, functional ability, and quality of life after PFF is a German population-based prospective cohort study based on statutory health insurance data and individually linked survey data from different time points including information on the currently used medication. This present analysis refers to the participants' baseline interviews (about 3 months following PFF) conducted from 2018 to 2019 in the participants' private surroundings. Results: The study population comprised 444 participants (mean age: 81.2 years, 71.0% female). Half of them reported high intensity pain, and the mean value for the EuroQol visual analogue scale was 50.8. Most commonly used analgesics were metamizole and tilidine/naloxone. Among participants with high intensity pain, 21.9% received only PRN pain medication and 17.2% no pain medication at all. Overall, 61.5% of participants presented any (printed) medication plan and only 25.2% a “federal standardized medication plan” (BMP). Conclusion: As a substantial number of patients reports high intensity pain about 3 months following a PFF, the large proportion of those receiving no or only PRN pain medication raises questions regarding the appropriateness of the therapy. The overall low utilization of the BMP indicates potential for improvement.

description: Facing the growing competition in the European food market, the purpose of this paper is to assess European country competitiveness at the sector level in the intra-EU market over the last fifteen years, comparing the evolution of the food industry, where firms have had to reshape strategies to maintain market position, and agricultural sector, where changes in Common agricultural policy have forced farms to face market trends. The analysis of competitiveness was carried out by assessing trade indices (EMS, RCA, RXA, RMA, NEI). Cluster analysis was also run to classify groups of countries with similar features in terms of competitive performance over the 1991-2006 period. The country that profited most from market integration in both sectors, reaching a high level of competitiveness was Spain, followed by Germany and Italy which gained competitiveness especially in the food industry. The United Kingdom had the worst performance, with a big decrease in indices, followed by France and Netherlands, still among the first but with lower indices.

description: In the last years the expression environment and the concern in relation to it became common. However, the environmental question, nowadays a social and sociological problem, has been constructed along human history, gaining new and different aspects and leading to different types of conflicts. Under an apparent “consensus” about the importance of the environment there are power conflicts to define, among others, the meaning of environment, the origin and solutions of the environmental problems and the forms of relations between society and nature, which influence the entire functioning of the society. A first step to advance in the discussion about this theme may be understanding that environment or nature is not so “natural”. Therefore, we propose to discuss how the predominant conceptions about solid scope we point out the environmental conflicts in public policies that have been reinforcing the importance of changes in power relations so that a serious an consistent environmental policy can be developed. The elaboration of this discussion was supported by the thoughts of Pierre Bourdieu, Andrew Vincent, Karl Polanyi, Boaventura de Sousa Santos, among others.

description: The objective of the work was to identify and characterize the agribusiness companies concerning the use of the theory of capital structure for its financial activity. The capital structure is one of great importance, involving both investments and financings (both the capital of external parties' and their own). Methodologically, the research was characterized as descriptive conclusive, through an intentional sample of 69 agribusiness companies in the south of Minas Gerais. The objective was to know the characteristics as to the constitution of their own capital and that of external parties, in function of its investments and financing operations. The results showed that, in general, the action of the capital structure in generating values for the company has not been applied. Its use by most of the companies is related to the change of the capital structure through the medium rate of return. Therefore, the companies will rather work with their own capital in relation to the external capital, because they consider that the cost of capital of the existing loan policies in the market is high. Thus, the financial decisions are more related to investment opportunities than to the optimum combination of their own capital or the external capital.

description: Canonical forms of two-qubits under the action of stochastic local operations and classical communications (SLOCC) offer great insight for understanding non-locality and entanglement shared by them. They also enable geometric picture of two-qubit states within the Bloch ball. It has been shown (Verstraete et.al. {Phys. Rev. A, 64, 010101(R) (2001)) that an arbitrary two-qubit state gets transformed under SLOCC into one of the {\em two} different canonical forms. One of these happens to be the Bell diagonal form of two-qubit states and the other non-diagonal canonical form is obtained for a family of rank deficient two-qubit states. The method employed by Verstraete et.al. required highly non-trivial results on matrix decompositions in $n$ dimensional spaces with indefinite metric. Here we employ an entirely different approach -- inspired by the methods developed by Rao et. al., (J. Mod. Opt. 45, 955 (1998)) in classical polarization optics -- which leads naturally towards the identification of two inequivalent SLOCC invariant canonical forms for two-qubit states. In addition, our approach results in a simple geometric visualization of two-qubit states in terms of their SLOCC canonical forms.

description: At supranuclear densities, explored in the core of neutron stars, a strong phase transition from hadronic matter to more exotic forms of matter might be present. To test this hypothesis, binary neutron-star mergers offer a unique possibility to probe matter at densities that we can not create in any existing terrestrial experiment. In this work, we show that, if present, strong phase transitions can have a measurable imprint on the binary neutron-star coalescence and the emitted gravitational-wave signal. We construct a new parameterization of the supranuclear equation of state that allows us to test for the existence of a strong phase transition and extract its characteristic properties purely from the gravitational-wave signal of the inspiraling neutron stars. We test our approach using a Bayesian inference study simulating 600 signals with three different equations of state and find that for current gravitational-wave detector networks already twelve events might be sufficient to verify the presence of a strong phase transition. Finally, we use our methodology to analyze GW170817 and GW190425, but do not find any indication that a strong phase transition is present at densities probed during the inspiral.

description: Considering that the concepts of dynamic production system and traditional system are placed in opposite sides of a continuum, the critical factor for the companies is in finding the break-even point desired to maximize the results and to reduce costs. The aim of this paper is to verify the situation of the manufacturing company when using characteristics of both flexible production system and static system to keep a good level of service and to reduce operational costs. The qualitative research was based on a case study of a great nourishing branch company. The results shows that the company is located inside of continuum considered, thus getting a satisfactory balance between the corresponding level of service to the customer and operational costs. It was concluded that the traditional production system and the flexible system are not excluding between itself. The real situation of the companies has shown that is necessary to use both advantages of one and another system to adjust it of the market demands and to brighten up possible negative impacts of this adjustment in the organization, as the increase of the operational costs.

The first has a pattern speed of Omega_P,Carina,1=16.5^{+1.2}_{-1.4sys}+/-1.1_{stat} (km/s)/kpc, while the second has Omega_P,Carina,2=29.8^{+0.6}_{-1.3sys}+/-1.3_{stat} (km/s)/kpc. The Perseus arm located at larger galactic radii exhibits only one clear set with Omega_P,Perseus=20.0^{+1.7}_{-1.2sys}+/-1.6_{stat} (km/s)/kpc. The Perseus and "slower" Carina arms are most probably part of an m=4 set. The Orion "armlet" appears to have a pattern speed of Omega_P,Orion=28.9 ^{+1.3}_{-1.2sys}+/-0.8_{stat} (km/s)/kpc. In other words, both the "faster" Carina arm and the Orion arm are nearly corotating with the solar system.

description: Necrotizing pancreatitis with superinfection of necrotic tissue is associated with a high rate of complications and mortality. The step-up approach is a well-established treatment strategy for necrotizing pancreatitis, emphasizing minimally invasive and endoscopic interventions before considering surgical options. Minimally invasive strategies often involve percutaneous drainage of collections, which carries the risk of persisting cutaneous pancreatic fistulas. Since there is currently no guidance for managing this scenario, we present a novel treatment approach that utilized tissue glue to occlude a persisting and clinically compromising percutaneous fistula. In addition, we summarize the current knowledge in the treatment of percutaneous pancreatic fistulas and provide a potential therapeutic algorithm for further evaluation.

description: The real-space RG approach is applied to study critical temperatures of system consisting of interacting spin chains of spin S=1 with an inner antiferromagnetic exchange which form a honeycomb crystal lattice. Using anisotropic Heisenberg model we calculate critical temperature as a function of anisotropic parameter and the ratio of interchain and intrachain interactions. A comparison our results with those obtained from RGRS calculations for the same model of spin-1/2 on a square lattice is given.
New Predictions for generalized spin polarizabilities from heavy baryon chiral perturbation theory

description: We extract the next-to-next-to-leading order results for spin-flip generalized polarizabilities (GPs) of the nucleon from the spin-dependent amplitudes for virtual Compton scattering (VCS) at ${\cal O}(p^4)$ in heavy baryon chiral perturbation theory. At this order, no unknown low energy constants enter the theory, allowing us to make absolute predictions for all spin-flip GPs. Furthermore, by using constraint equations between the GPs due to nucleon crossing combined with charge conjugation symmetry of the VCS amplitudes, we get a next-to-next-to-next-to-leading order prediction for one of the GPs. We provide estimates for forthcoming double polarization experiments which allow to access these spin-flip GPs of the nucleon.

description: The present article aimed at to characterize the pig farmers associated to the Regional Cooperative of Passos’ pig farmers, MG, according to the perception of the information value to the cost-benefit use of Information Technology (IT). This research has mixed the use of qualitative and quantitative collection of data techniques. In a first exploratory phase, semi-structured interviews were accomplished with 4 pig farmers and later 14 closed questionnaires were applied among the pig farmers associated to the cooperative. It was observed that the decision of adoption of IT is linked to the perception of the information value and to the benefit of control tools for the rural entrepreneurs in relation to the activity. The results allow a classification of the pig farmers in agreement with the value sensed by the information and to the benefits of the technological tools for administration as facilitator of the diffusion of tools of technology of information and the size of the activity in relation to the value of the cost-benefit attributed do IT.

description: Signal transmission between neurons requires exocytosis of neurotransmitters from the lumen of synaptic vesicles into the synaptic cleft. Following an influx of Ca2+, this process is facilitated by the Ca2+ sensor synaptotagmin-1. The underlying mechanisms involve electrostatic and hydrophobic interactions tuning the lipid preferences of the two C2 domains of synaptotagmin-1; however, the details are still controversially discussed. We, therefore, follow a multidisciplinary approach and characterize lipid and membrane binding of the isolated C2A and C2B domains. We first target interactions with individual lipid species, and then study interactions with model membranes of liposomes. Finally, we perform molecular dynamics simulations to unravel differences in membrane binding. We found that both C2 domains, as a response to Ca2+, insert into the lipid membrane; however, C2A adopts a more perpendicular orientation while C2B remains parallel. These findings allow us to propose a mechanism for synaptotagmin-1 during membrane fusion.

description: The existence of massive stellar black hole binaries (MBHBs), with primary black hole (BH) masses $\ge 31 \, M_\odot$, was proven by the detection of the gravitational wave (GW) event GW150914 during the first LIGO/Virgo observing run (O1), and successively confirmed by seven additional GW signals discovered in the O1 and O2 data. By adopting the galaxy formation model \texttt{GAMESH} coupled with binary population synthesis (BPS) calculations, here we investigate the origin of these MBHBs by selecting simulated binaries compatible in mass and coalescence redshifts. We find that their cosmic birth rates peak in the redshift range $6.5 \leq z \leq 10$, regardless of the adopted BPS. These MBHBs are then old systems forming in low-metallicity ($Z \sim [0.01-0.1] \, Z_{\odot}$), low-stellar-mass galaxies, before the end of cosmic reionization, i.e. significantly beyond the peak of cosmic star formation. GW signals generated by coalescing MBHBs open up new possibilities to probe the nature of stellar populations in remote galaxies, at present too faint to be detected by available electromagnetic facilities.

description: Cooperative is an organizational form of collective property which obeys a series of universal principles for leading the administration. The incomplete separation between property and control and the difficult access to the generated residues result in specific problems and hinder managerial action. The present article, according to the Theory of the Agency, discusses relation between the performance of an organizational form that, by means of the power of the principles need to act into the social development whereas keeping itself economically viable when competing with market oriented organizations and with the expectations of their associates. A questionnaire was developed and applied to the associates of a rural credit cooperative. The answers were treated according to the factorial analysis, which identified associates interest factors. Those factors of interest were compared with the cooperative performance. It was concluded that the associate expects the return on the social capital applied in the cooperative together with a superior quality service, or at an inferior market price. It is understood that there is mixed motivation in the associates expectations, which acts under investor and user logic. The cooperative, according to the identified performance, has shown significant evolution in the indicators that allows deducing the expectations attendance.

description: In this work, the relation between muon production in extensive air showers and features of hadronic multiparticle production at low energies is studied. Using CORSIKA, we determine typical energies and phase space regions of secondary particles which are important for muon production in extensive air showers and confront the results with existing fixed target measurements. Furthermore possibilities to measure relevant quantities of hadron production in existing and planned accelerator experiments are discussed.
