description: Passive multi-target tracking applications require the integration of multiple spatially distributed sensor measurements to distinguish true tracks from ghost tracks. A popular multi-target tracking approach for these applications is the particle filter implementation of Mahler's probability hypothesis density (PHD) filter, which jointly updates the union of all target state space estimates without requiring computationally complex measurement-to-track data association. Although this technique is attractive for implementation in computationally limited platforms, the performance benefits can be significantly overshadowed by inefficient sampling of the target birth particles over the region of interest. We propose a multi-sensor extension of the adaptive birth intensity PHD filter described in (Ristic, 2012) to achieve efficient birth particle sampling driven by online sensor measurements from multiple sensors. The proposed approach is demonstrated using distributed time-difference-of-arrival (TDOA) and frequency-difference-of-arrival (FDOA) measurements, in which we describe exact techniques for sampling from the target state space conditioned on the observations. Numerical results are presented that demonstrate the increased particle density efficiency of the proposed approach over a uniform birth particle sampler.

description: A series of 4-arylamido 5-methylisoxazole derivatives incorporating benzimidazole was designed and synthesised by conformational restriction of an in-house type II FMS inhibitor. Kinase profiling of one compound revealed interesting features, with increased inhibitory potency towards FLT3 and concomitant loss of potency towards FMS. Several benzimidazole derivatives 5a–5g and 6a–6c containing various hydrophobic moieties were synthesised, and their inhibitory activity against FLT3 was evaluated. Specifically, 5a, 5-methyl-N-(2-(3-(4-methylpiperazin-1-yl)-5-(trifluoromethyl)phenyl)-1H-benzo[d]imidazole-5-yl) isoxazole-4-carboxamide, exhibited the most potent inhibitory activity against FLT3 (IC50 = 495 nM), with excellent selectivity profiles.

description: We study the impact of loss-aversion and the threat of catastrophic damages, which we jointly call threshold concerns, on international environmental agreements. We aim to understand whether a threshold for dangerous climate change is as an effective coordination device for countries to overcome the global free-riding problem and abate sufficiently to avoid disaster. We focus on loss-averse countries negotiating either under the threat of either high environmental damages (loss domain), or low damages (gain domain). Under symmetry, that is when countries display identical degrees of threshold concern, we show that such beliefs have a positive effect on reducing the emission levels of both signatories to the treaty and non-signatories, leading to higher global welfare and weakly larger coalitions of signatories. We then introduce asymmetry, by allowing countries to differ in the degree of concern about the threat of disaster. We show that stable coalitions are mostly formed by the countries with higher threshold concern. When enough countries having no threshold concern could cause the coalition size to diminish, regardless of the other countries have strong or mild threshold concerns.

description: We investigate the inflation of Universe in a model of four dimensional dilatonic gravity with a massive dilaton field $Φ$. The dilaton plays simultaneously the roles of an inflation field and a quintessence field. It yields a sequential {\em hyper}-inflation with a graceful exit to asymptotic de Sitter space-time, which is an attractor, and is approached as $\exp(-\sqrt{3Λ^{obs}} ct/2)$. The time duration of the inflation is reciprocal to the the mass of the dilaton: $Δt_{infl}\sim m_{{}_Φ}^{-1}$. The typical number of e-folds in the simplest model of this type is shown to be realistic without fine tuning.

description: Concentration levels in U.S. agriculture are high and rising. As downstream competition declines, marketing opportunities for producers are constrained to—in some cases—a single buyer. Processors in thin markets (those with few purchasers, low trading volume, and low liquidity) could use informational advantages to depress farm-level prices for commodities (compared to a competitive market). Moreover, the low volume of trading in thin markets makes it difficult for participants and observers to gather market information and assess market performance. At the same time, many markets are moving away from traditional cash markets to bilateral contracts and vertical integration, which offer more opportunities for coordination and may foster efficiency gains that ultimately benefit producers. Both methods resolve information problems not addressed by the cash market, and forward-looking processors in many thin markets pay producers high enough prices to ensure a stable input supply. Thin market producers who can successfully enter and maintain contracts with these processors can achieve returns that meet or exceed their longrun costs. Attempting to impose greater competition on naturally thin markets can have adverse consequences for producers, processors, and consumers. However, small producers face new challenges in a thin market environment.

The results are interpreted in comparison with calculated emission patterns of an emission dipole placed near a solid surface, which establish a basic model for high-collection efficiency in solid-immersion fluorescence microscopy.

Schuverdt, On Augmented Lagrangian methods with general lower-level constraints, SIAM Journal on Optimization 18, pp. 1286-1309, 2008]. Complexity results that report its worst-case behavior in terms of iterations and evaluations of functions and derivatives that are necessary to obtain suitable stopping criteria are presented in this work. In addition, the computational performance of a new version of the method is presented, which shows that the updated software is a useful tool for solving large-scale constrained optimization problems.

 Type species. Paranecrocarcinus hexagonalis Van Straelen, 1936, by monotypy. The type species of Pseudonecrocarcinus is Necrocarcinus quadriscissus Noetling, 1881, by original designation.
 Remarks. The postfrontal slits, held to be diagnostic for the subfamily Paranecrocarcininae by Fraaije et al. (2008b: 201), may be present, albeit weak, in some other palaeocorystoids (Camarocarcinus, Cenomanocarcinus, Ferroranina n. gen.). These enigmatic slits may be interpreted as muscle scars for the ocular system. Additional observations are needed to determine their exact origin and taxonomic significance.

Self-shielding Effects on the Column Density Distribution of Damped Lyman Alpha Systems
Creators: name: Zheng, Zheng

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We calculate the column density distribution of damped Lyman alpha systems, modeled as spherical isothermal gaseous halos ionized by the external cosmic background. The effects of self-shielding introduce a hump in this distribution, at a column density N_{HI} \sim 1.6x10^{17} X^{-1} cm^{-2}, where X is the neutral fraction at the radius where self-shielding starts being important. The most recent compilation of the column density distribution by Storrie-Lombardi & Wolfe shows marginal evidence for the detection of this feature due to self-shielding, suggesting a value X \sim 10^{-3}. Assuming a photoionization rate Γ\sim 10^{-12} s^{-1} from the external ionizing background, the radius where self-shielding occurs is inferred to be about 3.8kpc. If damped Lyman alpha systems consist of a clumpy medium, this should be interpreted as the typical size of the gas clumps in the region where they become self-shielding. Clumps of this size with typical column densities N_H \sim 3x10^{20} cm^{-2} would be in hydrostatic equilibrium at the characteristic photoionization temperature \sim 10^4 K if they do not contain dark matter. Since this size is similar to the overall radius of damped \lya systems in Cold Dark Matter models, where all halos are assumed to contain similar gas clouds producing damped absorbers, this suggests that the gas in damped absorbers is in fact not highly clumped.

description: This article develops and tests a model that explains election outcomes on the basis of party strategy. It employs a new comparative dataset linking representative mass surveys from six European countries with Twitter analysis of campaign activity. The expectation is that parties whose issue agendas exploit electoral opportunities while avoiding risks will be rewarded at the polls. These risks and opportunities are modelled using issue yield, a general framework summarising public support, electoral alignments, and party credibility. Empirically, the article traces a three-step process: (1) the configuration of electoral risks and opportunities (which is captured through public opinion surveys) guides party communication (measured with Twitter data), and to the degree that (2) parties design their campaigns strategically (identified through issue yield), this in turn (3) improves their electoral performance (measured using official statistics). The analysis explains some of the most salient election outcomes of recent years.

description: Two decades after the first genetically engineered (GE) seeds became commercially available for major field crops, GE varieties have been widely adopted for U.S. corn, soybean, cotton, canola, and sugar beet production. The small, longstanding market for organically grown food (which excludes GE seed and material) continues to expand and a market for conventionally grown foods produced without GE seed has also emerged. In order to maintain the integrity of GE-differentiated markets, organic farmers—and other farmers using non-GE seeds—employ a variety of practices to avoid the accidental mixing of GE material in their crops. This report examines organic and conventional product markets in the United States. It describes commonly used coexistence practices and discusses the economic impacts when GE material is detected in organic crops.

Capture and Critical Scattering of a Long Cosmic String by a Rotating Black Hole

Year: 2002
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The capture of a straight, infinitely long cosmic string by a rotating black hole with rotation parameter $a$ is considered. We assume that a string is moving with velocity $v$ and that initially the string is parallel to the axis of rotation of the black hole and has the impact parameter $b$. The string can be either scattered or captured by the black hole. We demonstrate that there exists a critical value of the impact parameter $b_c(v,a)$ which separates these two regimes. Using numerical simulations we obtain the critical impact parameter curve for different values of the rotation parameter $a$. We show that for the prograde motion of the string this curve lies below the curve for the retrograde motion. Moreover, for ultrarelativistic strings moving in the prograde direction and nearly extremal black holes the critical impact parameter curve is found to be a multiply valued function of $v$. We obtain real time profiles of the scattered strings in the regime close to the critical. We also study critical scattering and capture of strings by the rotating black hole in the relativistic and ultrarelativistic regime and especially such relativistic effects as coil formation and wrapping effect.

description: The gases of the interstellar medium (ISM) possess orders of magnitude more mass than those of all the stars combined and are thus the prime component of the baryonic universe. With L-band surface sensitivity even better than the planned phase one Square-Kilometer-Array (SKA1), the Five-hundred-meter Aperture Spherical radio Telescope (FAST) promises unprecedented insights into two of the primary components of ISM, namely, the atomic hydrogen (HI) and the hydroxyl molecule (OH). We discuss here the evolving landscape of our understanding of ISM, particularly, its complex phases, the magnetic fields within, the so-called dark molecular gas (DMG), high velocity clouds, and the connection between local and distant ISM. We lay out, in broad strokes, several expected FAST projects, including an all northern-sky high-resolution HI survey (22,000 deg$^2$, 3\arcmin\ FWHM beam, 0.2 km/s), targeted OH mapping, searching for absorption or masing signals, and etc. Currently under commissioning, the commensal observing mode of FAST will be capable of simultaneously obtaining HI and pulsar data streams, making large-scale surveys in both science areas more efficient.

description: Atmospheric methane (CH4) concentrations have shown a puzzling resumption in growth since 2007 following a period of stabilization from 2000 to 2006. Multiple hypotheses have been proposed to explain the temporal variations in CH4 growth, and attribute the rise of atmospheric CH4 either to increases in emissions from fossil fuel activities, agriculture and natural wetlands, or to a decrease in the atmospheric chemical sink. Here, we use a comprehensive ensemble of CH4 source estimates and isotopic δ13C-CH4 source signature data to show that the resumption of CH4 growth is most likely due to increased anthropogenic emissions. Our emission scenarios that have the fewest biases with respect to isotopic composition suggest that the agriculture, landfill and waste sectors were responsible for 53 ± 13% of the renewed growth over the period 2007-2017 compared to 2000-2006; industrial fossil fuel sources explained an additional 34 ± 24%, and wetland sources contributed the least at 13 ± 9%. The hypothesis that a large increase in emissions from natural wetlands drove the decrease in atmospheric δ13C-CH4 values cannot be reconciled with current process-based wetland CH4 models. This finding suggests the need for increased wetland measurements to better understand the contemporary and future role of wetlands in the rise of atmospheric methane and climate feedback. Our findings highlight the predominant role of anthropogenic activities in driving the growth of atmospheric CH4 concentrations.

Disorder introduces localized transverse-magnetic (TM) modes into the band gap of the ideal crystal. The level spacing statistics is found to approach the Poisson distribution for these modes. In contrast, for TM modes outside the band gap and for transverse-electric (TE) modes at all frequencies, the level spacing statistics follows the Wigner-Dyson distribution.

description: A dynamic operations and investment simulation model was applied to catfish farming. The purpose was to identify some important aspects that should influence investment decisions in channel catfish farming enterprises. These results exhibited a number of economic relations of which the following were most important: (1) When initial average profits were $0.20 per pound and the initial price of land, buildings, and equipment was close to $800 per acre, the initial investment policy of the firm was one of continuous purchase of new capacity. (2) Higher initial average profits resulted in larger maximum capactities up to a limiting size, beyond further increases in profits resulted in increases in net worth, but not in capacity. (3) The investment policy of the firm was found to be very sensitive to initial prices of capacity higher than $800 per unit, and no new capacity was added if prices of capacity reached $1,500 per acre. (4) Profit accumulation and, thus, investment decisions were found to be sensitive to changes in the interest rate paid for financing new capacity.

description: There has been much interest in the blowout regime of plasma wakefield acceleration (PWFA), which features ultra-high fields and nonlinear plasma motion. Using an exact analysis, we examine here a fundamental limit of nonlinear PWFA excitation, by an infinitesimally short, relativistic electron beam. The beam energy loss in this case is shown to be linear in charge even for nonlinear plasma response, where a normalized, unitless charge exceeds unity. The physical basis for this effect is discussed, as are deviations from linear behavior observed in simulations with finite length beams.

description: Parties may rely on different issue agendas when tailoring their electoral campaigns in an attempt to win elections. This paper compares two key party issue strategies to examine which one the victorious Austrian Peoples’ Party (ÖVP) relied on the most during the 2017 Austrian election campaign vis-à-vis its main competitors. These two key party strategies are the ‘riding-the-wave’ model, which posits that parties focus on issues that currently concern voters the most and the recent ‘issue-yield model’, which instead suggests that parties adopt strategic behaviour targeting all those issues with genuine opportunities for electoral expansion. It is found that, compared to the other main parties in the 2017 Austrian election campaign, the ÖVP was the one most clearly relying on the issue-yield approach. These results have important implications for our understanding of electoral campaigns, party’s exploitation of issue strategies, and voter representation beyond the Austrian case.

Livestock Production/Industries

description: The catfish farming industry during the next few decades will face some crucial challenges. First, in order to adapt to the apparent increased production, well-organized efficient markets must be developed. The success of this industry during the next 10 years will primarily depend on the adequacy of this marketing strucutre. In addition, it will be necessary for the catfish industry to improve productivity and lower production costs to make catfish products competitive. These challenges notwithstanding, it is clear that the catfish industry will expand significantly during the next 15 to 20 years. The strucutre of the expanded catfish industry by that time will differ markedly from the current industry. Production techniques will be changed; the market will be more organized and progessive; and it is also likely that the fish will represent an improved genetic species, more adaptable to fish farming. At the present, pond reared catfish are marketed either live for fee pond fishing or as a fresh (unfrozen) product. Although the market for fresh catfish can be expanded, the analysis in this study shows clearly the need to develop new products to absorb the increased output of catfish. Radiation-pasteurization processing, it was found will undoubtedly pay substantial dividends in terms of direct public benefits. If the entire farm output were marketed in the fresh-irradiated form, then depending upon the discount rate, benefits would range between $31 and $45 million discounted value over an 11 year period. Likewise, the development of irradiation processed catfish products will increase net returns over and above all costs, including irradiation costs, to the industry. It would be expected that during the period 1975-1985, an irradiated product, selling in an unfrozen form, would generate 5 percent greater net revenue for the industry than would be generated by the sales of fresh catfish. This increase in net revenue will primarily be due to : (1) reduced spoilage loss (2) increased sales because of the elimination of the practice of short-buying, i.e., buying less than expected sales as a hedge against spoilage loss. Although there is little doubt that radiation processing can pay for itself in both the public and private sector, frozen catfish products represent a feasible alternative. If it were possible to market the same amount of catfish in the frozen form as in the fresh form, net revenues from irratdiated catfish. Marketing in the frozen form, in any case, adds less to the national income stream than irradiated. What is likely is that some combination of fresh and frozen catfish will make up the marketed forms. In this case, it is fully expected that irradiation-pasteurization will provide substantial public and private benefits.

description: This work explores the detailed chemistry of the Milky Way bulge using the HERMES spectrograph on the Anglo-Australian Telescope. Here we present the abundance ratios of 13 elements for 832 red giant branch and clump stars along the minor bulge axis at latitudes $b=-10^{\circ}, -7.5$ and $-5^{\circ}$. Our results show that none of the abundance ratios vary significantly with latitude. We also observe {\color{red}disk-like} [Na/Fe] abundance ratios, which indicates the bulge does not contain helium-enhanced populations as observed in some globular clusters. Helium enhancement is therefore not the likely explanation for the double red-clump observed in the bulge. We confirm that bulge stars mostly follow abundance trends observed in the disk. However, this similarity is not confirmed across for all elements and metallicity regimes. The more metal-poor bulge population at [Fe/H] $\lesssim -0.8$ is enhanced in the elements associated with core collapse supernovae (SNeII). In addition, the [La/Eu] abundance ratio suggests higher $r$-process contribution, and likely higher star formation in the bulge compared to the disk. This highlights the complex evolution in the bulge, which should be investigated further, both in terms of modelling; and with additional observations of the inner Galaxy.

description: We introduce a model of computation based on read only memory (ROM), which allows us to compare the space-efficiency of reversible, error-free classical computation with reversible, error-free quantum computation. We show that a ROM-based quantum computer with one writable qubit is universal, whilst two writable bits are required for a universal classical ROM-based computer. We also comment on the time-efficiency advantages of quantum computation within this model.

description: We propose and demonstrate a polarization-insensitive and high speed optical switch unit based on a silicon and lithium niobate hybrid integration platform. The presented device exhibits a sub nano-second switching time, low drive voltages of 4.97 V, and low power dissipation due to electrostatic operation. The measured polarization dependence loss was lower than 0.8 dB. The demonstrated optical switch could provide as a building block for polarization-insensitive and high-speed optical matrix switches.

H alpha rotation curves of Low Surface Brightness galaxies

description: We present high-resolution rotation curves of a sample of 26 low surface brightness galaxies. From these curves we derive mass distributions using a variety of assumptions for the stellar mass-to-light ratio. We show that the predictions of current Cold Dark Matter models for the density profiles of dark matter halos are inconsistent with the observed curves. The latter indicate a core-dominated structure, rather than the theoretically preferred cuspy structure.

description: Bournelyreidus carlilensis (Feldmann & Maxey, 1980) n. comb.
 Raninella carlilensis Feldmann & Maxey, 1980: 858.
 Remarks. Raninella carlilensis (see Feldmann & Maxey 1980: 858, text-figs. 1–3), as based on four specimens from the middle Turonian of Kansas (U.S.A.), is here reassigned to Bournelyreidus n. gen. The ventral sides of all specimens is poorly preserved, but the large mxp3 coxae, intercalated between the thoracic sternum and pterygostome, are well visible (Feldmann & Maxey 1980: 859, text-fig. 1A). There is a narrow junction between sternite 4 and the pterygostome, despite the fact that this is not sufficiently well-preserved in the type series. The rostrum is excavated; its tip and the outer orbital corners may be incompletely preserved in the type series. The pterygostome is tumid, ‘possessing two fairly deep sulci’ (Feldmann & Maxey 1980: 859; see also their text-fig. 1C), and the carapace bears two slender anterolateral spines. Raninella carlilensis, R. tridens and R. oaheensis appear to have a similar rostral region (Feldmann & Maxey 1980: 860, 861).

Publisher: name: Monash University
Year: 2019
Subjects: Clinical Psychology

description: This thesis reports on the development of a screening measure of distorted maternal representations (i.e., disturbed thoughts and feelings that a mother holds about the infant and self-as-parent) which could be used 1) clinically in order to identify dyads at risk of relational disturbance and offer early assessment and intervention when required, and 2) in research with high-risk populations. Mechanisms underlying early relational disturbance in high-risk populations and their impact on maternal and infant mental health are discussed.

description: We report small angle X-ray scattering (SAXS) measurements of the skyrmion lattice in two 200~nm thick Cu$_2$OSeO$_3$ lamellae aligned with the applied magnetic field parallel to the out of plane [110] or [100] crystallographic directions. Our measurements show that the equilibrium skyrmion phase in both samples is expanded significantly compared to bulk crystals, existing between approximately 30 and 50~K over a wide region of magnetic field. This skyrmion state is elliptically distorted at low fields for the [110] sample, and symmetric for the [100] sample, possibly due to crystalline anisotropy becoming more important at this sample thickness than it is in bulk samples. Furthermore, we find that a metastable skyrmion state can be observed at low temperature by field cooling through the equilibrium skyrmion pocket in both samples. In contrast to the behavior in bulk samples, the volume fraction of metastable skyrmions does not significantly depend on cooling rate. We show that a possible explanation for this is the change in the lowest temperature of the skyrmion state in this lamellae compared to bulk, without requiring different energetics of the skyrmion state.
