Geometric analysis of radiation damage connectivity in zircon, and its implications for helium diffusion

Abstract Geometrical modeling of radiation damages zones from α recoil and fission that accounts for their elongate nature provides new estimates of the doses required to reach percolation and full connectivity in zircon. Alpha recoil track damage percolates at doses from 2.5-3.1 × 1016 α/g based on our calculations, about two orders of magnitude lower than previous estimates, with the difference partially due to elongation and partially due to decay chains creating pre-made networks of connected tracks. This dose level is far below that required for metamictization, and suggests that α recoil track percolation has no effect on macroscopic or unit-cell properties, at least as measured to date. However, fission tracks percolate at a dose of approximately 1.9 × 1018 α/g, the approximate level formerly ascribed to α recoil damage percolation and correlating with various transitions in material properties, such as an inflection in the relationship between dose and macroscopic swelling. Consideration of the undamaged regions between damage zones indicates that c-axis-parallel channels are frequently interrupted, at the micrometer scale at very low doses and tens of nanometers at usual doses in natural zircon, with the probable effect of decreasing diffusivity anisotropy. The percolation and further interconnectivity of α recoil damage corresponds with a general minimum in diffusivity and maximum in closure temperature in zircon, indicating that α recoil damage percolation does not make a grain “leaky”, but instead quite the opposite. Instead, the onset of poor He retentivity at high damage levels correlates with fission-track percolation. Some of these results are non-intuitive with respect to the trapping model of He diffusivity reduction, and the alternative mechanism of tortuosity is discussed.
The first Slovene automatically compiled dictionary of abbreviations

Abbreviations are difficult to deal with (Gabrovsek, 1994) and represent a growing phenomena present in all languages. The scope of this article is to present the first Slovene automatically compiled dictionary of abbreviations. In the paper we present how we automatically extract abbreviation-expansion pairs out of newspaper texts and obtain genuine pairs, how we cope with the automatic editing phase and add language qualifiers to expansions and transform non-nominative expansions into nominative. The first Slovene automatically compiled dictionary of abbreviations is available online, free of charge, on the web site of Termania. It is the first dictionary produced automatically from newspaper articles with the help of algorithms. Algorithms represent a link between the text and the semi automatic production of a dictionary of abbreviations. That is why the production and further development of algorithms is essential and useful for lexicographers.
The Effect of Spots on the Luminosity Spread of the Pleiades

Cool spots on the surface of magnetically active stars modulate their observed brightnesses and temperatures, thereby affecting the stellar locus on the H-R diagram. Recent high-precision space-based photometric surveys reveal the rotational modulation from spots on stars in young clusters, including K2 monitoring of the 125 Myr old Pleiades cluster. However, light curves reveal only the asymmetries in the visible spot distributions rather than the total sizes of spots on stellar surfaces, which causes a discrepancy between the spot coverage measured by photometric and spectroscopic observations. In this paper, we simulate photometric variability introduced by randomly distributed starspots on a 125 Myr old coeval cluster. Our simulation results show that randomly distributed small spots on the stellar surface would explain the discrepancy that the photometric observations only reveal 10%–40% of the spot coverage measured by spectra. The colors and luminosities of photospheres are modeled for a range of photospheric temperature, spot coverage, and spot temperature. The colors and luminosities of a simulated population are then compared to the luminosity spread of Pleiades members, excluding the 25% of candidates that are identified as non-members with Gaia DR2 astrometry. The observed luminosities of Pleiades members have a standard deviation of 0.05 dex, which could be entirely explained by spots with a star-to-star standard deviation of spot coverage of 10%, but with an average coverage area that is not well constrained.
A Lower Bound for the End-to-End Distance of the Self-Avoiding Walk

Abstract For an $N$ -step self-avoiding walk on the hypercubic lattice ${{Z}^{d}}$ , we prove that the meansquare end-to-end distance is at least ${{N}^{4/(3d)}}$ times a constant. This implies that the associated critical exponent $v$ is at least $2/(3d)$ , assuming that $v$ exists.
Fiber level for laying hens during the growing phase

Feeding management of laying hens has been focused on the direct influence of nutrient intake on weight gain, especially at growing phase. This study evaluates nutrient digestibility, performance, development of the digestive tract, body composition, and bone quality of two strains of laying hens fed with different levels of neutral detergent fiber (NDF) during the growing phase from the 7th to the 12th week of age. A total of 1,296 birds were distributed in a completely randomized design in a 2 x 3 factorial arrangement (two strains x three levels of NDF) with four replicates of 54 birds per treatment. Semi-heavy (Hy Line Brown) and light-strain (Lohman LSL) pullets were allotted to dietary treatments consisting of 14.50, 16.50, and 18.50% NDF. An interaction between strains and NDF levels was observed only for feed/gain ratio and light-strain pullets had lower performance with 18.50% NDF. The increasing levels of NDF in the diet reduced the coefficients of digestibility of dry matter, nitrogen and gross energy, and the values of metabolizable energy. Higher levels of NDF in the diet increased the relative weight of liver and intestines and reduced gizzard weight. It was also observed differences between bone quality and composition of the femur and tibia of light and semi-heavy hens. The increase in NDF level in ration for growing phase laying hens above 14.50% decreases the nutrient digestibility and the metabolizable energy of the diet; however, it does not affect the carcass composition, bone quality, feed intake, and weight gain, although it may impair feed conversion of light-strain pullets.
The subdivision and zonation of interglacial periods

Abstract. Es wird immer schwieriger, vergleichende Studien uber die zahlreichen Pollendiagramme eines Interglazials innerhalb Nordwesteuropas oder aber verschiedener Interglaziale dieses Raumes zu machen, und zwar wegen der Mannigfaltigkeit der Zonierungssysteme, die die einzelnen Autoren anwenden. Dennoch haben aber Iversen (1958) und Andersen (1966) gezeigt, das in jedem der bisher untersuchten Interglaziale ahnliche Zyklen der Vegetationsentwicklung und der Bodenbildung abgelaufen sind. Die Verfasser legen dar, das in jeder Interglazialzeit 4 Perioden der Vegetationsentwicklung festgestellt werden konnen und das diese als naturliche biostratigraphische Zonen angesehen werden konnen, basierend auf dem Charakter der Pollengemeinschaften. Diese Perioden sind: Zone I, die Pre-temperate Zone, Betula und Pinus dominieren; Zone II, die Early-temperate Zone, Vorherrschaft der Baume des Eichenmischwaldes; Zone III, die Late-temperate Zone, in zunehmendem Mase beherrscht durch spat einwandernde warmeliebende Baume, wie Carpinus und Abies; Zone IV, die Post-temperate Zone, wiederum beherrscht durch boreale Baume, wie Pinus und Betula. Diese Zonierung kann fur fast alle interglazialen Pollendiagramme Nordwesteuropas verwandt werden. Geringe Veranderungen der Vegetation, und zwar regional, lokal oder seral, konnen als Unterzonen beschrieben werden, ohne die Hauptzuge und den Zweck dieses Zonierungssystems zu storen.
Comparison of Traditional, Flipped, and Hybrid Teaching Methods in an Electrical Engineering Circuit Analysis Course

This research builds on recent studies which have assessed advantages and disadvantages of a flipped classroom as compared to a traditional face-to-face classroom in Electrical Engineering Circuit Analysis courses. Flipped classrooms afford more opportunity for problem solving activities with students reading and viewing pre-recorded lectures prior to each in-class session. A hybrid classroom incorporates components of both traditional face-to-face and online learning allowing for greater flexibility in enhancing the learning and improving the understanding of course material. We applied all three teaching pedagogies in a Circuit Analysis class in a recent semester at a first-tier public research university. Students were surveyed at the end of the semester to assess their perceptions of the course, confidence in performing tasks, and interest in a fully on-line course. Task competencies surveyed included: Knowing the basics of instruments used in electrical engineering; Measuring voltages and currents using instruments; Building a variety of AC/DC circuits; Analyzing and modeling circuit performance using simulation tools; Understanding the purpose or function of a presented circuit; Building a circuit based upon results of a design calculation. We elaborate further on the pros and cons of all three teaching methods, summarize students’ perceptions and make suggestions based on the survey results and student comments.
Real‐time, reliable magnitudes for large earthquakes from 1 Hz GPS precise point positioning: The 2011 Tohoku‐Oki (Japan) earthquake

The early warning issued after the onset of the Mw9.0 Tohoku‐Oki earthquake significantly underestimated its magnitude, saturating, 120 seconds after the earthquake began, at Mw8.1. Here we investigate whether real‐time deformation data from Japan's dense network of continuously‐recording Global Positioning System (GPS) stations could have been used to provide a more reliable rapid estimate of the earthquake's magnitude, and ultimately a more robust tsunami forecast. We use precise point positioning in real‐time mode with broadcast clock and orbital corrections to give station positions every 1 s. We then carry out a simple static inversion on a subset of stations to determine the portion of the fault that slipped and the earthquake magnitude. Unlike most previous methods, our method produces estimates of seismic moment before the earthquake rupture has completed. We find that the deformation data allow a robust magnitude estimate just ∼100 s after the earthquake onset. We also investigated the density of stations required for a robust moment magnitude estimate. Fewer than 1 station every 100 km are needed. We recommend that GPS data be incorporated into earthquake early warning systems for regions at threat from large magnitude earthquakes and tsunamis.
An In-Depth Look at Prior Art in Fast Round-Robin Arbiter Circuits

Arbiters are found where shared resources exist such as busses, switching fabrics, processing elements. Round-robin is a fair arbitration method, where requestors get near-equal shares of a common resource or service. Round-robin arbitration (RRA) finds use in network switches/routers and processor boards/systems as well as many other applications that have concurrency. Today's electronic systems require arbiters with hundreds of ports (e.g., switching fabrics with virtual I/O queues) and clock speeds near the limits of even the latest microelectronics fabrication processes/libraries. Achieving high clock speeds in the presence of large number of ports is only possible with highly parallel arbiter architectures. This paper presents an in-depth literature survey of previous work on this problem. It looks at RRA work in the literature in a bigger context, then defines the typical RRA problem (RRA_typical), and specifically investigates work on fast architectures that solve the RRA_typical problem. There are five such works that are really competitive. This report takes a very in-depth look at these works. It explains each architecture and how/why it works from a unique perspective that cannot be found in the original publication of that architecture. It also proposes improvements to these architectures. We wrote generators for the improved versions of these architectures. We will share a summary of synthesis results in this report – although a detailed account of how these results were obtained and their analysis is the subject of another (upcoming) publication.
Effect of nitrogen and sulphur nutrition on storage protein quality in soybean [Glycine max (L.) Merrill]

The relative availabilities of nitrogen and sulphur can modulate seed storage protein composition in grain legumes and cereals. Soybean contains two major seed storage proteins, glycinins and I²-conglycinins that account for approximately 70% of total protein and their composition is affected by nitrogen and sulphur supplies. The present study demonstrated the effect of sulphur (Gypsum @ 20 kg S ha-1 ) and recommended a dose of nitrogen (Urea @ 31.25 kg N ha-1 ) alone or in combination on accumulation patterns of various protein fractions and protein quality in soybean seeds under agro-climatic conditions of Punjab. Application of nitrogen or sulphur alone decreased the relative proportion of I²-subunit of purified I²-conglycinin fraction than control. The acidic polypeptides of glycinin fraction of globulin and 11S/7S ratio were increased in all the treatments in comparison to control, and the maximum increase was reported in the combined application of gypsum with the recommended dose of urea. The lower proportion of total 7S, increased acidic polypeptides and improved 11S:7S ratio by combined treatment of nitrogen and sulphur suggests that gypsum @ 20 kg S ha-1 can be beneficial when applied along the recommended nitrogen dose to improve soybean protein quality.
English Language Teaching in Indonesia: A Continuous Challenge in Education and Cultural Diversity

The linguistic situations and conditions in Indonesia are quite complex by their own natures as more than seven hundred vernaculars with their various dialects from a great number of ethnic groups have been used as media of communication in the country. Accordingly, the success of English teaching in Indonesia cannot be freed from the students' cultural backgrounds, values, customs, and beliefs as well as the political standpoint of the government regarding this foreign language. English language teaching has then undergone more than four changes in its curriculum since the country's independence and brought no significant impact upon the learning outcomes. This study reveals the substantial unconstructive influence of the students' cultures and the non-conducive language environment affecting their language acquisition. Other aspects related to the teachers' performance and class preparations equally contribute to the ineffective classroom interactions. This study offers some practical suggestions to cope with those problems.
System Trust and Cooperation: The Case of Recycling Behavior

Abstract: In this paper, I develop and test the hypothesis that system trust – trust in the reliability, ef-fectiveness, and legitimacy of social institutions – promotes cooperation in social dilemmas and the provision of public goods, focusing then on the example of recycling. I discuss three models that can explain recycling behavior (rational choice, low-cost hypothesis, dual-process theory) and show how they link incentives and attitudes. All three models claim that incentives are an important factor mediating the attitude-behavior link, but they develop con-tradicting hypotheses about the direction of this effect. I use survey data collected by Sonderskov and Daugbjerg (2011) to advance an empirical test. I find a positive and significant interaction between the attitude of system trust and recycling costs, as well as a negative and significant interaction between system trust and recycling benefits. The data rule out the rational choice and low-cost hypothesis explanation of recycling behavior. Instead, they indicate that attitudes moderate the impact of the incentive structure, increasing cooperation in collective action dilemmas irrespective of the costs associated with compliance.
Main Line Fault Localization Methodology in Smart Grid – Part 1: Extended TM2 Method for the Overhead Medium-Voltage Broadband over Power Lines Networks Case

These three papers cover the overall methodology for the identification and localization of faults that occur in main transmission and distribution lines when broadband over power lines (BPL) networks are deployed across the transmission and distribution power grids, respectively. In fact, this fault case is the only one that cannot be handled by the combined operation of Topology Identification Methodology (TIM) and Instability Identification Methodology (FIIM). After the phase of identification of main distribution line faults, which is presented in this paper, the main line fault localization methodology (MLFLM) is applied in order to localize the faults in overhead medium-voltage BPL (OV MV BPL) networks. The main contribution of this paper, which is focused on the identification of the main distribution line faults, is the presentation of TM2 method extension through the adoption of coupling reflection coefficients. Extended TM2 method is analyzed in order to identify a main distribution line fault regardless of its nature (i.e., short- or open-circuit termination). The behavior of the extended TM2 method is assessed in terms of the main line fault nature and, then, its results are compared against the respective ones during the normal operation, which are given by the original TM2 method, when different main distribution line fault scenarios occur. Extended TM2 method acts as the introductory phase (fault identification) of MLFLM.
Squeezing quadrature rotation in the acoustic band via optomechanics

We examine the use of optomechanically generated squeezing to obtain a sensitivity enhancement for interferometers in the gravitational-wave band. The intrinsic dispersion characteristics of optomechanical squeezing around the mechanical frequency are able to produce squeezing at different quadratures over the spectrum, a feature required by gravitational-wave interferometers to beat the standard quantum limit over an extended frequency range. Under realistic assumptions we show that the amount of available squeezing and the intrinsic quadrature rotation may provide, compared to similar amounts of fixed-quadrature squeezing, a detection advantage. A significant challenge for this scheme, however, is the amount of excess noise that is generated in the unsqueezed quadrature at frequencies near the mechanical resonance.
Ricardian Equivalence Hypothesis in the Sub-Sahara African Countries

The validity of the Ricardian equivalence proposition remains disputed in spite of the numerous empirical work. This study utilized panel ARDL estimation approach to investigate the evidence of Ricardian Equivalence Hypothesis in five Sub-Sahara African countries, namely Botswana, Ghana, Gambia, Nigeria, and Kenya over the period of 1981~2014. Our results show that GDP per capita and interest rate have significant positive impacts on private consumption, whereas government debt, government spending, government interest payment on the outstanding debt have negative impacts on private consumption. Ricardian equivalence hypothesis, which states that private consumption remains unchanged regardless of government’s spending, does not hold in Sub-Sahara African countries.

Granger causality in volatility between Australian equity and debt markets: A Bayesian analysis

This paper is concerned with identifying Granger causality in the volatilities of returns between the Australian equity and debt markets. Using a bivariate stochastic volatility model previously described by Yu and Renate (2006), we estimate and compare four causal models between equity market volatility, and the short term and long term debt market volatilities. The causal models are compared with two non-causal, bivariate stochastic volatility models. Models comparisons are performed using the Deviance Information Criteria (DIC). Modelling results suggest that bond market volatility Granger causes equity market volatility. Equity volatility and money market volatility show evidence of Granger causality between the two, but no dominate causal direction is identified suggesting causal feedback between the two market volatilities.
Correction of seafloor magnetotelluric data for topographic effects during inversion

[1] The large contrast in electrical conductivity between seawater and the underlying seafloor accumulates boundary electric charges which can severely distort observed electric and magnetic fields. For marine magnetotelluric (MT) studies, correcting this topographic effect is critical to obtaining accurate conductivity models for the mantle. Previously, correction for topography was based on the thin sheet approximation which breaks down at periods under ∼1000 s in the deep ocean. This paper introduces an analysis method for seafloor MT data which combines removal of three-dimensional (3-D) topographic effects with inversion of the data for 2-D structure. The observed MT impedance is first corrected to a flat-lying seafloor datum using the observed bathymetry without invoking the thin sheet approximation. The corrected MT response is then inverted in a flat seafloor model space. Because of coupling between topographic effects and deeper structure, the correction and inversion steps are iterated until changes in each become small. The procedure is verified using synthetic and real data. Tests for synthetic 3-D topography over a half-space show that the method closely recovers the true half-space model after a few iterations. The procedure is also applied to real data collected in the Mantle Electromagnetic and Tomography (MELT) experiment on the East Pacific Rise at 17°S.
Fair Allocation through Social Norm

In this research, fair allocation problem has been investigated in terms of efficiency and envy-freeness. The simplest allocation scenario has been chosen for this study. Ordinary Allocation Procedure and Social Norm Allocation Procedure have been proposed, implemented and tested. Three cascaded degrees of compromise values among three different-sized of agents have been set to test. The experimental results show that the Social Norm Allocation Procedure is able to reach more effectively and fairly allocated the resources among agents than the Ordinary Allocation Procedure in every agreement constant. Additionally, the smaller size of agents tends to give a better achievement when comparing with the larger size under the same agreement value.
