Type Information Utilized Event Detection via Multi-Channel GNNs in Electrical Power Systems

Event detection in power systems aims to identify triggers and event types, which helps relevant personnel respond to emergencies promptly and facilitates the optimization of power supply strategies. However, the limited length of short electrical record texts causes severe information sparsity, and numerous domain-specific terminologies of power systems makes it difficult to transfer knowledge from language models pre-trained on general-domain texts. Traditional event detection approaches primarily focus on the general domain and ignore these two problems in the power system domain. To address the above issues, we propose a Multi-Channel graph neural network utilizing Type information for Event Detection in power systems, named MC-TED, leveraging a semantic channel and a topological channel to enrich information interaction from short texts. Concretely, the semantic channel refines textual representations with semantic similarity, building the semantic information interaction among potential event-related words. The topological channel generates a relation-type-aware graph modeling word dependencies, and a word-type-aware graph integrating part-of-speech tags. To further reduce errors worsened by professional terminologies in type analysis, a type learning mechanism is designed for updating the representations of both the word type and relation type in the topological channel. In this way, the information sparsity and professional term occurrence problems can be alleviated by enabling interaction between topological and semantic information. Furthermore, to address the lack of labeled data in power systems, we built a Chinese event detection dataset based on electrical Power Event texts, named PoE. In experiments, our model achieves compelling results not only on the PoE dataset, but on general-domain event detection datasets including ACE 2005 and MAVEN.
What's in a Picture?: Evidence of Discrimination from Prosper.com

We find evidence of significant racial disparities in a new type of credit market known as peer-to-peer lending. Loan listings with blacks in the attached picture are 25 to 35 percent less likely to receive funding than those of whites with similar credit profiles. Despite the higher average interest rates charged to blacks, lenders making such loans earn a lower net return compared to loans made to whites with similar credit profiles because blacks have higher relative default rates. These results provide insight into whether the discrimination we find is taste-based or statistical.
Being an entrepreneur in nursing : challenges to nurses in a strategic leadership position

Faculdades Integradas de Taquara, Taquara, RS, Brazil. Universidade Federal do Rio Grande do Sul, Porto Alegre, RS, Brazil. Confl icts of interest: the authors declare that there are no confl icts of interest in the conception, operationalization, or writing of the research results. Abstract Objective: To identify challenges to the development of entrepreneurial behaviors, from the perspective of nurses in a strategic position of leadership. Methods: This was a qualitative, descriptive, and exploratory study. Participants were twelve female nurses, working in a strategic leadership position in different health organizations and services of a municipality in southern Brazil. A semi-structured interview was administered between September and November of 2017. Analysis of the thematic content was conducted using the steps of pre-analysis, material exploration, treatment of results, and interpretation. Results: It was revealed that nurses in a strategic leadership position presented important challenges in the development of entrepreneurial behaviors, represented by the structures described in the thematic categories: movements of entrepreneurial actions by nurses in strategic positions of leadership; being an entrepreneur in a strategic leadership position: (im)mobilizing situations; learning to be an entrepreneur: challenges of advanced responsibility. Conclusion: In the context of the study, the position occupied by nurses represents an unparalleled opportunity for the dissemination of an entrepreneurial culture in diverse professional settings, both in terms of strategic potential for management of people and processes, as well as in stimulating the development of entrepreneurial actions in care management, and management of health and nursing services. The study awakens the need to search for means and possibilities to allow for management of the paradoxes that permeate the reality of being a female nurse in a strategic position of leadership in healthcare and teaching institutions, which is not always a favorable situation.
DIMENSION INVAB1ANCE OF SUBDIVISIONS

iV-free ordered sets are uncommonly useful in the combinatorial theory of ordered sets. Recently, Habib [1] conjectured that the computational time-complexity of the problem to determine the dimension of an N-iree ordered set is polynomial. An approach to settling Habib's conjecture in the affirmative uses the popular idea of subdividing the edges of the diagram. Spinrad [3] has shown, by a clever example, that this obvious approach cannot succeed. In fact, our paper is inspired by an effort to settle Habib's conjecture in the negative, by using the same subdivision idea, albeit in a more sophisticated context than before. To this end we show that the dimension of an ordered set is unchanged for any subdivision of its completion, a result that seems to be of independent interest.
Effects of B . infantis on the Maternal Restraint Model of Depression

Depression during pregnancy is a significant public health issue, with 18% of pregnant women suffering from depressive symptoms. Prepartum depression is correlated with health complications in the mother, and with physical and behavioral abnormalities in the child. Psychotherapy provides relief to some, but access and compliance issues limit its efficacy, and the safety of antidepressant use during pregnancy has not been conclusively demonstrated. An alternative approach is to address the health of the gut brain axis, a bidirectional signaling pathway between gut microbiota and the central nervous system. Gut dysbiosis, an imbalance in gut microbe composition, is linked to psychiatric disorders, especially anxiety and depression. The consumption of probiotics, microbes beneficial to health, could potentially provide relief to pregnant women with depression and subsequently protect the child from deleterious effects of prepartum depression. Bifidobaterium infantis 35634 (B. infantis) has been studied in the context of irritable bowel syndrome and reduces systemic inflammatory biomarkers. The present study explored the role of the gut microbiome in prenatal and early postnatal development by exploring the effects of B. infantis supplementation on the maternal restraint model of depression in rats. Maternal restraint for 45 min three times per day, for six to seven days, significantly increased dams’ depressive behavior. Maternal restraint additionally increased offspring weights and depressive behavior. B. infantis supplementation tended to rescue these deficits, although effects did not reach significance. Additional research with a larger sample size is warranted to elucidate the efficacy of this intervention in improving the physical and psychological health of mother and infant.
Analysis of aerosol scattering coefficient measurements between 2006 and 2008 at El Arenosillo station

Aerosol scattering properties have been measured over two years (January 2006 to May 2008) at the monitoring station ESAT-El Arenosillo as part of the development of the “Laboratorio de Medida de Aerosoles” in situ into the scientific collaboration between INTA National Institute of Aerospace Technique of Spain) and “Atmospheric Optics Group of the University of Valladolid (GOA-UVA). This station belonging to INTA is located in the coastal area of the province of Huelva (Southwestern of Spain). Light scattering coefficient σsp and hemispheric back-scattering coefficient σbsp were measured using a 3-wavelengths (450, 550 and 700 nm) integrating nephelometer of TSI Model 3563, under specified GAW dry conditions. Ångström exponent α has been also derived from the spectral scattering dependence and the hemispheric backscatter fraction b from the ratio σbsp/σsp. All these parameters have been carefully analyzed to investigate their general characteristics and features, as annual, seasonal and diurnal variability.
Part I : large unwrinkled axisymmetric deformations

Three theories for determination of the equilibrium states of initially flat, linearly elastic, rotationally symmetric, taut membranes are considered: Föppl-von Kármán theory, Reissner’s theory, and a new generalization of Reissner’s theory that does not restrict the strains to be small. Attention is focused on annular membranes, but circular membranes are also treated. Large deformations are allowed, and the equilibrium equations are written in terms of transverse, radial, and circumferential displacements. Problems considered include radial stretching, transverse displacement of the inner edge, an adhesive punch pull-off test on a circular blister, transverse pressure, ponding of annular and circular membranes, a vertical distributed load with a vertically sliding outer membrane edge, pull-in (snap-down, jump-to-contact) instability of a MEMS device, torsion of the inner or outer edge of a stretched membrane, and a combination of radial stretching, vertical displacement, and torsion. Results for the three theories are compared. Closed-form solutions are available in a few cases, but usually a shooting method is utilized to obtain numerical solutions for displacements, strains, and stresses. Conditions for the onset of wrinkling are determined. In the second part of this two-part study, small vibrations about equilibrium configurations are analyzed.
The Impact of red heartwood on drying characteristics and mass transfer coefficients in beech wood

The effects of red heartwood on mass transfer coefficients and drying characteristics in beech wood (Fagus orientalis L.) were studied here. In this regard, some properties were measured within the dried boards containing red heartwood; then they were compared with those of the normal wood. The properties included longitudinal diffusion and specific air permeability coefficients, drying rate, radial and tangential shrinkage, crack occurrence, residual stresses (casehardening), and warp. Specimens were dried in a laboratory convective kiln under a constant temperature of 60 oC and a relative humidity (RH) of 40% until the final moisture content (MC) of 8%. For evaluation of the permeability and diffusion coefficients, other selected specimens were dried under milder condition. The results revealed that red heartwood decreased drying rate, but it increased the shrinkage, casehardening, and consequently drying defects. In this connection, the existence of tyloses in the vessel elements of red heartwood resulted in a considerably significant decrease in the longitudinal permeability; however, tyloses seemed to have no significant decreasing effect on the longitudinal diffusion coefficient. 1 Department of Wood and Paper Science & Technology, Karaj Branch, Islamic Azad University, Karaj, Iran. 2 Department of Wood Science & Technology, Faculty of Civil Engineering, Shahid Rajaee Teacher Training University, Tehran, Iran. 3 Department of Wood and Paper Science & Technology, Faculty of Natural Resources, University of Tehran, Karaj, Iran. * Corresponding author: Hamid Reza Taghiyari (Ph.D.); htaghiyari@srttu.edu & htaghiyari@yahoo.com; Wood Science & Technology Dept., Faculty of Civil Engineering, Shahid Rajaee Teacher Training University (SRTTU), Lavizan, Shabanloo St., Tehran, Iran; Cellphone: (+ 98) 0930-2005235; Fax: (+ 98-21) 22970021.

Ultimate Bearing Capacity of Composite Shell Annular Foundations in Cohesionless Soil

The foundation shape effects on the stress distribution induced in the soil. Moreover, it has influence on the failure mechanism of the soil. For these reasons, it plays an important role in the ultimate bearing capacity of the foundation. Due to lack of materials, the new design methods attempt to utilize the least amount of material and achieve the maximum efficiency. If shell elements are employed in composite foundations, and the interaction effects are considered, the cost can be reduced. This paper aims to compare the geotechnical performance of the composite annular shell foundation with that of the annular one. For this purpose, the ultimate bearing capacity and the settlement of these foundations are experimentally modeled for various shell angles. The findings prove that the ultimate bearing capacity of the composite foundations is more than that of the annular one. Furthermore, it is observed that increasing the shell angle reduces the ultimate bearing capacity. Moreover, the shell efficiency factor is decreased by increasing the soil relative density. This phenomenon shows that the shells perform more appropriately in low-density soils. Additionally, a novel relation is proposed for predicting the ultimate bearing capacity of the composite shell. It is worth emphasizing that adding the edge beam to composite foundations improves its performance in settlements during failure. Moreover, the efficiency of foundations with edge beams is more than the ones without beam in soils with any density. Hence, using of shells in annular foundation enhances its ultimate bearing capacity. Review History: Received: 7 March 2017 Revised: 23 April 2017 Accepted: 6 June 2017 Available Online: 13 June 2017
Stiffness and Damping Aspects of Fiber Reinforced Elastomeric Bearings as Anti-Seismic Devices

The use of fiber reinforced elastomeric bearings as simple and cheap anti-seismic devices for high-rising structures was discussed in numerous publications. In this paper the influence of the exact tuning of horizontal stiffness and damping on the efficiency of horizontal elastic joints in shear walls is presented. It is shown that an exact determination of the bearing properties is necessary to improve the results. The lack of adequate formulas in the current design codes is pointed out 1 Research Associate, email: ulrich.gerhaher@boku.ac. at 2 Adj.

Surface and Interface Relaxation of Current Carrier Spins in Graphite and its Intercalation Compounds

The method of conduction ESR (CESR) has been actively used in studies of graphite and graphite intercalation compounds (GICs) for determining the kinetic parameters of the spin carriers from an analysis of the Conduction ESR (CESR) line shape [1-11]. For a long time the analysis of the CESR line shape for the graphite itself [1,2,11-14] and its intercalation compounds [3-10] was carried out using the well-known theory of Dyson [15] and Kaplan [16] not including the surface spin relaxation of current carriers by the standard procedures of Feher and Kip [17], Kodera [18], and Pifer and Magno [19]. However, in a strict sense, Dyson’s theory [15] of the CESR is applicable only for infinite metal plates of arbitrary thickness with isotropic conductivity and a single carrier type. Although experiments have shown the validity of using this theory for analyzing the CESR line shape in metal plates with finite dimensions, its applicability to the case of graphite and GICs with large anisotropy of skin depths, as well as anisotropy of carrier diffusion, is not obvious. First, it was pointed out by Müller et al. [20]. Saint Jean et al. [8] and Blinowski et al. [21] have studied this problem mathematically strictly using the Maxwell equations. To obtain the correct CESR line shape analysis in the case of anisotropic conductors, they have extended the Dyson theory [15] by taking into account the anisotropy of conductivity and diffusion. Herewith, authors, as well as all preceding researchers, implied that in GICs it is possible to neglect the surface spin relaxation effects.
Optimal Inventory Model with Two Level Storage Under Ramp Type Demand

This paper presents an EOQ model for the two level of Inventory for deteriorating items with demand rate as a ramp type function of time and a two parameter Weibull distribution is used to represent the distribution of the time for deterioration both in OW (Own Warehouse) and RW (Rented Warehouse). As the holding cost is higher in RW than OW, ’k’ units of RW is transferred in bulk from RW to OW at a time and the total amount is transferred in n shipments. A fixed cycle is considered and the shortages are partially backlogged. The objective of the paper is to find the optimal replenishment policyfor the problem.
DTC, DPC and Nonlinear Vector Control Strategies Applied to the DFIG Operated at Variable Speed

In this paper we present the modeling and control designs for a variable-speed constantfrequency wind energy conversion system using double fed induction generator (DFIG). The aim of this paper is to design and compare two distinct control strategies to control the rotor side power converter and two control strategies to control the grid side power converter. For the rotor side converter (RSC), a nonlinear vector control strategy using the second Lyapunov approach is firstly developed. Secondly, a direct torque control strategy, constructed around two hysteresis controllers that allow flux and torque regulation, is presented. For the grid side converter (GSC), the network voltage vector oriented control based on PI controllers and a direct power control strategy constructed around two hysteresis controllers that allow grid injected power regulation, are presented, respectively. Simulation results have shown good performances of the wind energy converter system operate under typical wind variations and every propose control strategies. Key-Words: Double fed induction generator Direct torque control Nonlinear vector control -Lyapunov approach Network voltage oriented control Direct power control.
INFLUENCE OF AGE-0 YELLOW PERCH ABUNDANCE ON WALLEYE POPULATIONS IN TWO EASTERN SOUTH DAKOTA LAKES

Eastern South Dakota lakes typically range from mesotrophic to hypereutrophic based on the trophic state index, and prey supplies, whether they be macroinvertebrates or fishes, tend to be abundant. Thus, biologists often believe that quality of sport fishing is more closely linked to interannual variation in recruitment (i.e., year-class strength) than to prey availability for sport fishes. Here, we document two case histories that challenge this premise. We noted significant (P ≤ 0.002) increases in age-0 yellow perch (Perca flavescens), a common prey for walleye (Stizostedion vitreum), abundance between 2000 and 2001 in Sinai and Waubay lakes. For example, larval yellow perch abundance (number/100 m) was 723 times higher in 2001 than 2000 in Lake Sinai and 46 times higher in Lake Waubay. Similarly, juvenile yellow perch abundance as indexed by seine hauls increased by a factor of 251 in Waubay Lake and a factor of 385 in Lake Sinai between 2000 and 2001. In conjunction with these increases in age-0 yellow perch as available prey, walleye condition factors significantly (P ≤ 0.004) increased in 2001 compared to 2000 for walleyes ≤51 cm in both lakes. In addition, age-0 walleye growth rates increased, but not always significantly. Based on these two examples, we suggest that prey availability may be more important to sport fish population structure and dynamics in eastern South Dakota lakes than previously believed.
Working Paper n o 1081 Identifying and Estimating the Effects of Unconventional Monetary Policy in the Data : How to Do It and What Have We Learned ?

How should one identify monetary policy shocks in unconventional times? Are unconventional monetary policies as e¤ective as conventional ones? And has the transmission mechanism of monetary policy changed in the zerolower bound era? The recent nancial crisis led Central banks to lower their interest rates in order to stimulate the economy, and interest rates in many advanced economies hit the zero lower bound. As a consequence, the traditional approach to the identi cation and the estimation of monetary policy faces new econometric challenges in unconventional times. This article aims at providing a broad overview of the recent literature on the identi cation of unconventional monetary policy shocks and the estimation of their e¤ects on both nancial as well as macroeconomic variables. Given that the prospects of slow recoveries and long periods of very low interest rates are becoming the norm, many economists believe that we are likely to face unconventional monetary policy measures often in the future. Hence, these are potentially very important issues in practice. *Corresponding author: Barbara Rossi, CREI, Univ. Pompeu Fabra, c. Ramon Trias Fargas 25-27, 08005 Barcelona, Spain.

Sorption and Desorption of Nutrients in Seawater By Zeolite

Seawater contains large amounts of cations. Since this resource is abundant and cheap, it can be a laudable source of plant nutrients. The objective of this study was to investigate the extent to which zeolite could sorb and desorb nutrients in different concentrations of seawater. Results indicated that Zeolite sorbed Na and Mg. The highest percentage of Na and Mg sorbed was 76.19 and 36.69%, respectively obtained for 10% seawater. The desorption study indicated that the higher the seawater concentration used during the sorption, the higher the Na and Mg desorbed. Passing diluted seawater through zeolite leached out K and Ca to the extent that the effluent was concentrated with the cations. This by-product solution can be used as a source of plant nutrients. However, high concentration of such cations in the solution caused high pH and EC, which means that the solution has to be diluted to meet the requirements of plants.
