description: Most of Melbourne’s drinking water comes from forested catchments which are largely closed to the public to minimise water quality risks. Potential disruptions to maintaining high quality and low cost drinking water include a growing population and a changing and variable climate. The expected introduction of Health Based Targets (HBTs) in the Australian Drinking Water Guidelines provides an important driver to deliver public health outcomes and provides a consistent framework to show best practice is being used to manage microbial risks at the source. Melbourne’s most important and protected water catchments feed into Silvan Reservoir. This study investigated the benefits and costs of integrated catchment management as a treatment process for drinking water supplied by the Silvan system. A facilitated participatory approach combined with benefit cost analysis (BCA) using the Investment Framework for Environmental Resources (INFFER) was used. This included an innovative approach to quantifying the risk of bushfire to Melbourne’s water supply within a BCA framework. Benefits and costs were assessed for nine options, two focussing on managing microbial risk to meet HBTs and seven to address bushfire risks. Protecting the Silvan Reservoir had the highest adjusted benefit cost ratio (BCR = 2.14) over 30 years. Protecting the whole system (including Upper Yarra and Thomson catchments) was marginally uneconomic (adjusted BCR = 0.93), but would be economically viable with some minor efforts to reduce project-based risks. Enhanced catchment management to protect against bushfire impacts was also close to being economically viable (BCR = 0.96). Innovative measures to reduce debris flow impacts was also promising (BCR = 1.30) whereas investment in filtration plants was poor (BCRs range 0.06 to 0.45).

description: Online antisemitism is hard to quantify. How can it be measured in rapidly growing and diversifying platforms? Are the numbers of antisemitic messages rising proportionally to other content or is it the case that the share of antisemitic content is increasing? How does such content travel and what are reactions to it? How widespread is online Jew-hatred beyond infamous websites and fora, and closed social media groups? However, at the root of many methodological questions is the challenge of finding a consistent way to identify diverse manifestations of antisemitism in large datasets. What is more, a clear definition is essential for building an annotated corpus that can be used as a gold standard for machine learning programs to detect antisemitic online content. We argue that antisemitic content has distinct features that are not captured adequately in generic approaches of annotation, such as hate speech, abusive language, or toxic language. We discuss our experiences with annotating samples from our dataset that draw on a ten percent random sample of public tweets from Twitter. We show that the widely used definition of antisemitism by the International Holocaust Remembrance Alliance can be applied successfully to online messages if inferences are spelled out in detail and if the focus is not on intent of the disseminator but on the message in its context. However, annotators have to be highly trained and knowledgeable about current events to understand each tweet's underlying message within its context. The tentative results of the annotation of two of our small but randomly chosen samples suggest that more than ten percent of conversations on Twitter about Jews and Israel are antisemitic or probably antisemitic. They also show that at least in conversations about Jews, an equally high number of tweets denounce antisemitism, although these conversations do not necessarily coincide.

description: The interaction of magnetic fields with astrophysical plasmas drives many impressive displays of particle acceleration and impulsive energy release. Within the following work we present a brief overview of magnetic reconnection and energy release mechanisms. We then explore these impulsive energy releases in the form of solar flares (Chapter 2), flaring in the X-ray and optical on other stellar types (Chapter 4), and finally we explore the nature of what could be the brightest microquasar known. The RHESSI spectroscopy of flares in the hard X-ray regime confirms the presence of a deviation from the power law nature of the non-thermal flare spectra. These “knees” allow us to test our current knowledge of particle interactions during a flare. The results of this show that the high resolution spectra do not produce an unphysical result in the underlying accelerated electron spectrum. This gives us greater confindence in our current theoretical understanding of energetic particle interaction. Our observations in both the X-ray (Section 4.1) and the optical (Section 4.2) reveal, as expected, that the flare stars observed were mid M-dwarf stars and cool red dwarfs. Finally we come to the case of 1RXS J 162848.1-415241, possibly the brightest microquasar known to date. As it turns out it is probably not a microquasar at all but more likely is another example of magnetic field interaction, a many spotted RS CVn System. Overall we see magnetically driven events producing some of the most violent energy outburst in the galaxy, and have taken a few steps forward towards a better understanding of the underlying nature of both the events themselves and the objects on which they play out.

description: The high dimensionality of hyperspectral images consisting of several bands often imposes a big computational challenge for image processing. Therefore, spectral band selection is an essential step for removing the irrelevant, noisy and redundant bands. Consequently increasing the classification accuracy. However, identification of useful bands from hundreds or even thousands of related bands is a nontrivial task. This paper aims at identifying a small set of highly discriminative bands, for improving computational speed and prediction accuracy. Hence, we proposed a new strategy based on joint mutual information to measure the statistical dependence and correlation between the selected bands and evaluate the relative utility of each one to classification. The proposed filter approach is compared to an effective reproduced filters based on mutual information. Simulations results on the hyperpectral image HSI AVIRIS 92AV3C using the SVM classifier have shown that the effective proposed algorithm outperforms the reproduced filters strategy performance.

description: Knowledge graph embeddings are now a widely adopted approach to knowledge representation in which entities and relationships are embedded in vector spaces. In this chapter, we introduce the reader to the concept of knowledge graph embeddings by explaining what they are, how they can be generated and how they can be evaluated. We summarize the state-of-the-art in this field by describing the approaches that have been introduced to represent knowledge in the vector space. In relation to knowledge representation, we consider the problem of explainability, and discuss models and methods for explaining predictions obtained via knowledge graph embeddings.

description: We study the evolution of the cosmic-mass-density contrast beyond the Robertson-Walker geometry including the small contribution of acceleration. We derive a second-order evolution equation for the density contrast within the spherical model for CDM collisionless fluid including the cosmological constant, the expansion and the non-vanishing vector of acceleration. While the mass-density is not seriously affected by acceleration, the mass-density contrast changes its shape at smaller redshifts even for a small amount of the acceleration parameter. This could help to resolve current controversial results in cosmology from measurements of WMAP, gravitational lensing, XMM X-ray cluster or type Ia supernovae data, etc.

description: Impact craters, as "lunar fossils", are the most dominant lunar surface features and occupy most of the Moon's surface. Their formation and evolution record the history of the Solar System. Sixty years of triumphs in the lunar exploration projects accumulated a large amount of lunar data. Currently, there are 9137 existing recognized craters. However, only 1675 of them have been determined age, which is obviously not satisfactory to reveal the evolution of the Moon. Identifying craters is a challenging task due to their enormous difference in size, large variations in shape and vast presence. Furthermore, estimating the age of craters is extraordinarily difficult due to their complex and different morphologies. Here, in order to effectively identify craters and estimate their age, we convert the crater identification problem into a target detection task and crater age estimation into a taxonomy structure. From an initial small number of available craters, we progressively identify craters and estimate their age from Chang'E data by transfer learning (TL) using deep neural networks. For comprehensive identification of multi-scale craters, a two-stage craters detection approach is developed. Thus 117240 unrecognized lunar craters that range in diameter from 532 km to 1 km are identified. Then, a two-stage classification approach is developed to estimate the age of craters by simultaneously extracting their morphological features and stratigraphic information. The age of 79243 craters larger than 3 km in diameter is estimated. These identified and aged craters throughout the mid and low-latitude regions of the Moon are crucial for reconstructing the dynamic evolution process of the Solar System.

description: Chaotic diffusion on periodic orbits (POs) is studied for the perturbed Arnol'd cat map on a cylinder, in a range of perturbation parameters corresponding to an extended structural-stability regime of the system on the torus. The diffusion coefficient is calculated using the following PO formulas: (a) The curvature expansion of the Ruelle zeta function. (b) The average of the PO winding-number squared, $w^{2}$, weighted by a stability factor. (c) The uniform (nonweighted) average of $w^{2}$. The results from formulas (a) and (b) agree very well with those obtained by standard methods, for all the perturbation parameters considered. Formula (c) gives reasonably accurate results for sufficiently small parameters corresponding also to cases of a considerably nonuniform hyperbolicity. This is due to {\em uniformity sum rules} satisfied by the PO Lyapunov eigenvalues at {\em fixed} $w$. These sum rules follow from general arguments and are supported by much numerical evidence.

description: We present some results of numerical simulations of a globular cluster orbiting in the central region of a triaxial galaxy on a set of 'loop' orbits. Tails start forming after about a quarter of the globular cluster orbital period and develop, in most cases, along the cluster orbit, showing clumpy substructures as observed, for example, in Palomar 5. If completely detectable, clumps can contain about 7,000 solar masses each, i.e. about 10% of the cluster mass at that epoch. The morphology of tails and clumps and the kinematical properties of stars in the tails are studied and compared with available observational data. Our finding is that the stellar velocity dispersion tends to level off at large radii, in agreement to that found for M15 and Omega Centauri.

description: In the remote sensing community, Land Use Land Cover (LULC) classification with satellite imagery is a main focus of current research activities. Accurate and appropriate LULC classification, however, continues to be a challenging task. In this paper, we evaluate the performance of multi-temporal (monthly time series) compared to mono-temporal (single time step) satellite images for multi-label classification using supervised learning on the RapidAI4EO dataset. As a first step, we trained our CNN model on images at a single time step for multi-label classification, i.e. mono-temporal. We incorporated time-series images using a LSTM model to assess whether or not multi-temporal signals from satellites improves CLC classification. The results demonstrate an improvement of approximately 0.89% in classifying satellite imagery on 15 classes using a multi-temporal approach on monthly time series images compared to the mono-temporal approach. Using features from multi-temporal or mono-temporal images, this work is a step towards an efficient change detection and land monitoring approach.

description: Many questions are still open regarding the physical mechanisms behind the magnetic switching in GdFeCo alloys by single optical pulses. Phenomenological models suggest a femtosecond scale exchange relaxation between sublattice magnetization as the driving mechanism for switching. The recent observation of thermally induced switching in GdFeCo by using both several picosecond optical laser pulse as well as electric current pulses has questioned this previous understanding. This has raised the question of whether or not the same switching mechanics are acting at the femo- and picosecond scales. In this work, we aim at filling this gap in the understanding of the switching mechanisms behind thermal single-pulse switching. To that end, we have studied experimentally thermal single-pulse switching in GdFeCo alloys, for a wide range of system parameters, such as composition, laser power and pulse duration. We provide a quantitative description of the switching dynamics using atomistic spin dynamics methods with excellent agreement between the model and our experiments across a wide range of parameters and timescales, ranging from femtoseconds to picoseconds. Furthermore, we find distinct element-specific damping parameters as a key ingredient for switching with long picosecond pulses and argue, that switching with pulse durations as long as 15 picoseconds is possible due to a low damping constant of Gd. Our findings can be easily extended to speed up dynamics in other contexts where ferrimagnetic GdFeCo alloys have been already demonstrated to show fast and energy-efficient processes, e.g. domain-wall motion in a track and spin-orbit torque switching in spintronics devices.

A universal nonlinear relation among boundary states in closed string field theory

description: We show that the boundary states satisfy a nonlinear relation (the idempotency equation) with respect to the star product of closed string field theory. This relation is universal in the sense that various D-branes, including the infinitesimally deformed ones, satisfy the same equation, including the coefficient. This paper generalizes our analysis (hep-th/0306189) in the following senses. (1) We present a background-independent formulation based on conformal field theory. It illuminates the geometric nature of the relation and allows us to more systematically analyze the variations around the D-brane background. (2) We show that the Witten-type star product satisfies a similar relation but with a more divergent coefficient. (3) We determine the coefficient of the relation analytically. The result shows that the alpha parameter can be formally factored out, and the relation becomes universal. We present a conjecture on vacuum theory based on this computation.

description: Saturn's largest satellite, Titan, transited the Crab Nebula on 5 January 2003. We observed this astronomical event with the {\it Chandra} X-ray Observatory. An ``occultation shadow'' has clearly been detected and is found to be larger than the diameter of Titan's solid surface. The difference gives a thickness for Titan's atmosphere of 880 $\pm$ 60 km. This is the first measurement of Titan's atmospheric extent at X-ray wavelengths. The value measured is consistent with or slightly larger than those estimated from earlier Voyager observations at other wavelengths. We discuss the possibility of temporal variations in the thickness of Titan's atmosphere.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We report the implementation of a cost-effective approximation method within the framework of time-dependent optimized coupled-cluster (TD-OCC) method [J. Chem. Phys. 148, 051101 (2018)] for real-time simulations of intense laser-driven multielectron dynamics. The method, designated as TD-OCEPA0, is a time-dependent extension of the simplest version of the coupled-electron pair approximation with optimized orbitals [J. Chem. Phys. 139, 054104 (2013)]. It is size extensive, gauge invariant, and computationally much more efficient than the TD-OCC with double excitations (TD-OCCD). We employed this method to simulate the electron dynamics in Ne and Ar atoms exposed to intense near infrared laser pulses with various intensities. The computed results, including high-harmonic generation spectra and ionization yields, are compared with those of various other methods ranging from uncorrelated time-dependent Hartree-Fock (TDHF) to fully-correlated (within the active orbital space) time-dependent complete-active-space self-consistent-field (TD-CASSCF). The TD-OCEPA0 results show a good agreement with TD-CASSCF ones for moderate laser intensities. For higher intensities, however, TD-OCEPA0 tends to overestimate the correlation effect, as occasionally observed for CEPA0 in the ground-state correlation energy calculations.

description: According to the subjective Bayesian interpretation of quantum mechanics (QBism), the instruments used to measure quantum systems are to be regarded as an extension of the senses of the agent who is using them, and quantum states describe the agent's expectations for what they will experience through these extended senses. How can QBism then account for the fact that (i) instruments must be calibrated before they can be used to `sense' anything; (ii) some instruments are more precise than others; (iii) more precise instruments can lead to discovery of new systems? Furthermore, is the agent `incoherent' if they prefer to use a less precise instrument? Here we provide answers to these questions.

description: A 3 dimensional analogue of Sakai's theory concerning the relation between rational surfaces and discrete Painlevé equations is studied. For a family of rational varieties obtained by blow-ups at 8 points in general position in ${\mathbb P}^3$, we define its symmetry group using the inner product that is associated with the intersection numbers and show that the group is isomorphic to the Weyl group of type $E_7^{(1)}$. By normalizing the configuration space by means of elliptic curves, the action of the Weyl group and the dynamical system associated with a translation are explicitly described. As a result, it is found that the action of the Weyl group on ${\mathbb P}^3$ preserves a one parameter family of quadratic surfaces and that it can therefore be reduced to the action on ${\mathbb P}^1\times {\mathbb P}^1$.

Risk and Uncertainty

description: This paper provides new insight into the meaning of several risk concepts (e.g., "lottery space," "measurable utility function," "risk aversion") of use in agricultural economics. Some surprising consequences of a mathematically rigorous approach, such as risk aversion with "convex data," are discussed. Applications to the agricultural economics literature are described.

description: A new, highly sensitive and selective chemosensing method has been developed for the detection of cyanide ion using benzamide hydrazone receptors (R1-R4). The sensing ability of these compounds towards CN− in the presence of Br −, HSO4−, Cl−, OH−, I−, F−, AcO−, NO2− and NO3− in DMF and DMF-Aqueous mixture (DMF:H2O, 9:1 v/v) was investigated. The binding characteristics of the probe with cyanide ions carried out by 1 H NMR titrations indicated the deprotonation of N-H group through H-bond interactions between benzamide hydrazones and cyanide ions; it has been theoretically supported by DFT. The binding constant (Ka) and stoichiometry of the host–guest complex formed was calculated by the Benesi–Hildebrand (B–H) plot, and strong interaction of the probe with CN- ions forming a 1:2 binding stoichiometry has been noted in this study. In a DMF and aqueous medium for CN− ion, the lower limit of detection (LOD in ppm) is compared to the limit of quantification (LOQ in ppm), which is quite better in terms of sensitivity.

description: The purpose of this paper is to present preliminary estimates of economies of size and optimal cropping patterns for vegetable production in the Connecticut River Valley. Linear programming results indicate substantial economies of size from farms up to $100,000 of gross returns and only marginal average cost savings thereafter. For the five farms analyzed, crop diversification is observed at optimal levels of output. With the exception of the two smallest farms, once output dropped to 90 percent of the optimal levels, farms specialized in one vegetable crop.

Robustagramma crassisaccus

description: Robustagramma crassisaccus Cui and Marshall, new species
(Figs. 192–199)
 As described for Robustagramma biangulatum except as follows.
 Body length 1.6–2.0 mm. Facial ridge of male with width between antennae similar to width of scape; facial ridge of female distinctly broader between antennae than width of scape. Eye height ca. 2.7 times genal height. Mid femur of male with a row of strong anteroventral setulae in addition of over 10 ventral proximal bristles.
 Male terminalia: Sternite 5 with 3–4 pairs of stout bristles. In lateral view, posteroventral margin of surstylus rounded. Ejaculatory apodeme ca. 1/3 as long as aedeagal apodeme. In anteroventral view, distiphallus with distal dorsal sclerites conspicuously extended outwardly.
Female terminalia: Spermathecae distinctly short and thick; single spermatheca with distal portion similar in length to basal portion; paired spermathecae with ducts nearly twice length of spermatheca.
Holotype (♂, DEBU) and paratypes (3 ♀, DEBU): VENEZUELA: Bolívar. Evergreen Dry Forest, FIT, vi– 12.vii.1987, S. & J. Peck.
Other paratypes: GUYANA: Rupununi Dist., Kurupukari, Essequibo R., 200ft, primary rainforest, dung traps, 9.x.1990, B. Hubley (6 ♂, 3 ♀, DEBU); Kurupukari, E. side Essequibo R., primary rainforest edge/field, malaise trap, 7–11.x.1990, B. Hubley and L. D. Coote (1 ♀, DEBU). VENEZUELA: Bolívar. 8 km N Guri, 200m, 16.vii–11.viii.1986, B. Gill (1 ♂, DEBU).
Etymology: The specific epithet refers to the short, thick spermathecae of this species.
 Comments: Robustagramma crassisaccus is identical to Robustagamma ovipennis (Duda) in many details, even in shapes of surstylus and cercus. Robustagramma crassisaccus, however, differs in the form of male sternite 5, having 3–4 pairs of short, stout bristles. Furthermore, the distal sclerite of the distiphallus of R. crassisaccus lacks medial spicules.

description: The objective of the paper is to derive a tax policy which yields an imputed value of an investment, in real terms, which is invariant with the rate of inflation. The approach explicitly introduces inflation into Samuelson's "fundamental theorem of tax-rate invariance." The results indicate that only real interest should be taxed and depreciation allowances should be equal to economic depreciation indexed for inflation.

description: Metallo-helicates are a commonly encountered assembly within supramolecular chemistry. Interest in these architectures stems from their inherent helical chirality which positions them for a diverse range of applications such as catalysis and non-linear optics (NLO). The current study uses Co(II) dinuclear double helicates as versatile supramolecular synthons. The ditopic ligand, L, features two tridentate quinolinyl-hydrazone binding sites imparting it with hydrogen bond donors and π-faces for secondary supramolecular interactions. Incorporation of L into [Co2(L)2]4+ helical assemblies results in a helical cationic supramolecular synthon with moieties predisposed to forming π-π stacking and hydrogen bond interactions. The single-crystal X-ray structures of [Co2(L)2]X4 (X = ClO4 −, BF4 − and CF3SO3 −) revealed a variety of anion dependent hydrogen bond networks arising through the interaction of the hydrazide hydrogen with the anion. These interactions in turn strongly influence the nature of the π-π stacking interactions of the quinoline moieties which can be analysed via the Hirshfield surface.

description: The correlation functions near higher-order glass-transition singularities are discussed for a schematic two-component model within the mode-coupling theory for ideal glass-transitions. The correlators decay in leading order like $-\ln(t/τ)$ and the leading correction introduces characteristic convex and concave patterns in the decay curves. The time scale $τ$ follows a Vogel-Fulcher type law close to the higher-order singularities.

description: We prove the first mathematical result relating the Yang-Mills measure on a compact surface and the Yang-Mills energy. We show that, at the small volume limit, the Yang-Mills measures satisfy a large deviation principle with a rate function which is expressed in a simple and natural way in terms of the Yang-Mills energy.
Sensitive dependence on initial conditions in transition to turbulence in pipe flow

description: The experiments by Darbyshire and Mullin (J. Fluid Mech. 289, 83 (1995)) on the transition to turbulence in pipe flow show that there is no sharp border between initial conditions that trigger turbulence and those that do not. We here relate this behaviour to the possibility that the transition to turbulence is connected with the formation of a chaotic saddle in the phase space of the system. We quantify a sensitive dependence on initial conditions and find in a statistical analysis that in the transition region the distribution of turbulent lifetimes follows an exponential law. The characteristic mean lifetime of the distribution increases rapidly with Reynolds number and becomes inaccessibly large for Reynolds numbers exceeding about 2200. Suitable experiments to further probe this concept are proposed.
