description: Group dynamic movement is a fundamental aspect of many species' movements. The need to adequately model individuals' interactions with other group members has been recognised, particularly in order to differentiate the role of social forces in individual movement from environmental factors. However, to date, practical statistical methods which can include group dynamics in animal movement models have been lacking. We consider a flexible modelling framework that distinguishes a group-level model, describing the movement of the group's centre, and an individual-level model, such that each individual makes its movement decisions relative to the group centroid. The basic idea is framed within the flexible class of hidden Markov models, extending previous work on modelling animal movement by means of multi-state random walks. While in simulation experiments parameter estimators exhibit some bias in non-ideal scenarios, we show that generally the estimation of models of this type is both feasible and ecologically informative. We illustrate the approach using real movement data from 11 reindeer (Rangifer tarandus). Results indicate a directional bias towards a group centroid for reindeer in an encamped state. Though the attraction to the group centroid is relatively weak, our model successfully captures group-influenced movement dynamics. Specifically, as compared to a regular mixture of correlated random walks, the group dynamic model more accurately predicts the non-diffusive behaviour of a cohesive mobile group.

description: We develop Coulomb gas pictures of strong and weak coupling regimes of supersymmetric Yang-Mills theory in five and four dimensions. By relating them to the matrix models that arise in Chern-Simons theory, we compute their free energies in the large N limit and establish relationships between the respective gauge theories. We use these correspondences to rederive the N^3 behaviour of the perturbative free energy of supersymmetric gauge theory on certain toric Sasaki-Einstein five-manifolds, and the one-loop thermal free energy of N=4 supersymmetric Yang-Mills theory on a spatial three-sphere.

description: Copper (Cu) is a resource that is essential in the successful transition towards a low-carbon, clean energy future. Currently, New Zealand imports 100% of its Cu inventory, despite known Cu deposits in New Zealand. Given the predicted future demand for Cu, and its certainty to become scarce due to dwindling reserves, supply-chain issues, and global political instability, understanding New Zealand’s potential for a domestic supply of socially and environmentally sustainable Cu is appropriate. In this report we present an overview of the current understanding of New Zealand’s potential Cu resources, with a focus on the Coromandel Peninsula where historic mining for Cu associated with porphyry systems has occurred. An up-to-date inventory of Cu resources throughout New Zealand and the Coromandel Peninsula is provided, as well as the first resource assessment ever completed for Cu in New Zealand. Based on known and undiscovered occurrences, porphyry Cu deposits are likely to yield the largest resources of Cu in New Zealand, with a potential resource of 1,965,600 t of Cu (>90% of all estimated Cu resources). Focusing on porphyry Cu systems in the Coromandel Peninsula, geochemical data from several sources, as well as new analyses undertaken for this study, were compiled to identify Cu ‘fertility’ signatures in Coromandel Peninsula plutonic rocks. Based on the limited dataset, some plutonic rocks show that they are prospective with respect to Cu ‘fertility’; however, given the limited dataset and significant advances in the understanding of porphyry Cu deposits globally, additional sampling and acquisition of a high-quality, comprehensive geochemical dataset across the Coromandel Peninsula is recommended to better understand New Zealand’s porphyry Cu resource potential

description: Chronic arsenic exposure results in higher risk of skin, lung, and bladder cancer, as well as cardiovascular disease and diabetes. The purpose of this study was to investigate the effects on expression of selected genes in the blood lymphocytes from 159 people exposed chronically to arsenic in their drinking water using a novel RT-PCR TaqMan low-density array (TLDA). We found that expression of tumor necrosis factor-α (TNF-α), which activates both inflammation and NF-κB-dependent survival pathways, was strongly associated with water and urinary arsenic levels. Expression of KCNA5, which encodes a potassium ion channel protein, was positively associated with water and toe nail arsenic levels. Expression of 2 and 11 genes were positively associated with nail and urinary arsenic, respectively. Because arsenic exposure has been reported to be associated with long QT intervals and vascular disease in humans, we also used this TLDA for analysis of gene expression in human cardiomyocytes exposed to arsenic in vitro. Expression of the ion-channel genes CACNA1, KCNH2, KCNQ1 and KCNE1 were down-regulated by 1-mM arsenic. Alteration of some common pathways, including those involved in oxidative stress, inflammatory signaling, and ion-channel function, may underlay the seemingly disparate array of arsenic-associated diseases, such as cancer, cardiovascular disease, and diabetes.

description: Oscillator phase noise has been shown to be one of the main performance limiting factors in full-duplex systems. In this paper, we consider the problem of self-interference cancellation with phase noise suppression in full-duplex systems. The feasibility of performing phase noise suppression in full-duplex systems in terms of both complexity and achieved gain is analytically and experimentally investigated. First, the effect of phase noise on full-duplex systems and the possibility of performing phase noise suppression are studied. Two different phase noise suppression techniques with a detailed complexity analysis are then proposed. For each suppression technique, both free-running and phase locked loop based oscillators are considered. Due to the fact that full-duplex system performance highly depends on hardware impairments, experimental analysis is essential for reliable results. In this paper, the performance of the proposed techniques is experimentally investigated in a typical indoor environment. The experimental results are shown to confirm the results obtained from numerical simulations on two different experimental research platforms. At the end, the tradeoff between the required complexity and the gain achieved using phase noise suppression is discussed.

description: The incidence of intra-night optical variability (INOV) is known to to differ significantly among different classes of powerful active galactic nuclei (AGN). A number of statistical methods have been employed in the literature for testing the presence of INOV in the light curves, sometimes leading to discordant results. In this paper we compare the INOV characteristics of six prominent classes of AGN, as evaluated using three commonly used statistical tests, namely the $χ^2-$test, the modified $C-$test and the $F-$test, which has recently begun to gain popularity. The AGN classes considered are: radio-quiet quasars (RQQs), radio-intermediate quasars (RIQs), lobe-dominated quasars (LDQs), low optical polarization core-dominated quasars (LPCDQs), high optical polarization core-dominated quasars (HPCDQs), and TeV blazars. Our analysis is based on a large body of AGN monitoring data, involving 262 sessions of intra-night monitoring of a total 77 AGN, using 1-2 metre class optical telescopes located in India. In order to compare the usefulness of the statistical tests, we have also subjected them to a `sanity check' by comparing the number of false positives yielded by each test with the corresponding statistical prediction. The present analysis is intended to serve as a benchmark for future INOV studies of AGN of different classes.

description: In this book chapter, we carefully examine how Vygotsky's cultural-historical perspective can be a valuable theoretical framework to elucidate ChatGPT's facilitation of second / foreign language acquisition. Core theoretical concepts from Vygotsky's works include perezhivanie, speech development, and the zone of proximal development (ZPD). Three foundational principles for understanding second language acquisition within this framework encompass: (1) considering the environment as a wellspring of the ideal forms of the target language, (2) emphasizing internalization through active and meaningful social interactions, and (3) acknowledging optimal second language acquisition when effectively scaffolded in the zone of proximal development of the individual. Furthermore, we underscore the significance of ChatGPT's capabilities, including providing input in the target language, simulating genuine conversations, responding to queries on various subjects, and furnishing feedback—essential functions for cultivating the process of learning a second or foreign language.

A steady diet of images. The European migrant crisis, border policy and political aesthetics
Creators: name: Vogt, Richard A.
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis sits at the ever-expanding margins of borders studies, focusing on the cultural and aesthetic significance of border constructions and regimes. Whilst building upon a base of key modern geopolitical literature, it engages with a reflection on whether the ongoing European Crisis is one of migrants, of borders, or of European identity itself. Events since 2015,and the European Union’s (EU)flawed response, challenge its vision of being a normative power in global politics. Through a lack of Union solidarity and ongoing evidence of hypocrisy, it is clear that the (re)fencing of Europe has become a Rorschach test for the continent as much as it has for the individual member states. From this flows a discussion around counter-hegemonic method, employing the concepts of political aesthetics, especially through visual regimes of news media and photojournalism. If political writings traditionally deal with the state and aesthetical writings with art and drama, the blending of the two enable to present new perspectives of the concept of Europe’s crisis. The necroaesthetics discussed deal with both the bodies of migrants, and the teichopolitical spaces of camps and (re)fenced borders. By concentrating on the violence of borders as racialised contact zones in their multiple and expanding manifestations , this approach helps to challenge and critique governmental narratives related to migration and its perceived threat to the political class. This can be seen through the European memento mori of a century of camps and barbed wire which provoke the hallucinatory presence of previous war images, and border barriers of the last century.

description: The radio source at the center of the cool core galaxy cluster RBS 797 (z=0.35) is known to exhibit a misalignment of its radio jets and lobes observed at different VLA-scale, with the innermost kpc-scale jets being almost orthogonal to the radio emission which extends for tens of kpc filling the X-ray cavities. Gitti et al. suggested that this peculiar radio morphology may indicate a recurrent activity of the central radio source, where the jet orientation is changing between the different outbursts due to the effects of supermassive binary black holes (SMBBHs). We aim at unveiling the nuclear radio properties of the brightest cluster galaxy (BCG) in RBS 797 and at investigating the presence of a SMBBH system in its center. We have performed new high-resolution observations at 5 GHz with the European VLBI Network (EVN), reaching an angular resolution of 9x5 mas^2 and a sensitivity of 36 microJy/beam. We report the EVN detection of two compact components in the BCG of RBS 797, with a projected separation of ~77 pc. We can envisage two possible scenarios: the two components are two different nuclei in a close binary system, or they are the core and a knot of its jet. Both interpretations are consistent with the presence of SMBBHs. Our re-analysis of VLA archival data seems to favor the first scenario, as we detect two pairs of radio jets misaligned by ~90 degrees on the same kpc scale emanating from the central radio core. If the two outbursts are almost contemporaneous, this is clear evidence of the presence of two active SMBHs, whose radio nuclei are unresolved at VLA resolution. The nature of the double source detected by our EVN observations in the BCG of RBS 797 can be established only by future sensitive, multi-frequency VLBI observations. If confirmed, RBS 797 would be the first SMBBH system observed at medium-high redshift at VLBI resolution. (abridged)

description: The article focuses on the problems of constructing mathematical models of mechanical oscillatory systems containing elastic and mass-and-inertia elements. It shows the possibilities of combining typical elementary links in some structural formations, called quasi-springs. Such constituent links have the same properties as conventional springs in commutation and transformation circuits. Features of dynamic stiffness of system in general and quasi-springs, in particular, are that dynamic stiffnesses take zero values and infinitely large ones. The authors propose a method for determining the frequencies of natural oscillations on the basis of using the concepts of the dynamic stiffness of a system. The work considers features of the formation of dynamic responses in systems whose elements make joint motions.

description: The positive effects of various perturbations introduced in a bidimensional photonic-crystal patterned membrane on its integrated absorption are investigated numerically and theoretically. Two phenomena responsible for the enhanced absorption observed are identified: an increase of the spectral density of modes, obtained thanks to folding mechanisms in the reciprocal lattice, and a better coupling of the modes with the incident light. By introducing a proper pseudodisordered pattern, we show that those two effects can be exploited so as to overcome the integrated absorption obtained for an optimized and single pattern unit cell photonic crystal.

description: Timing techniques offer powerful tools to study dynamical astrophysical phenomena. In the X-ray band, they offer the potential of probing accretion physics down to the event horizon. Recent work has used frequency and energy-dependent time lags as a tool for studying relativistic reverberation around the black holes in several Seyfert galaxies. This was achieved thanks to the evenly-sampled light curves obtained using XMM-Newton. Continuous-sampled data is however not always available and standard Fourier techniques are not applicable. Here, building on the work of Miller et al. (2010), we discuss and use a maximum likelihood method to obtain frequency-dependent lags that takes into account light curve gaps. Instead of calculating the lag directly, the method estimates the most likely lag values at a particular frequency given two observed light curves. We use Monte Carlo simulations to assess the method's applicability, and use it to obtain lag-energy spectra from Suzaku data for two objects, NGC 4151 and MCG-5-23-16, that had previously shown signatures of iron K reverberation. The lags obtained are consistent with those calculated using standard methods using XMM-Newton data.

description: The national truth© campaign has exposed U.S. youth to antismoking messages since 2000. Tobacco industry–sponsored campaigns, such as “Think. Don’t Smoke” (TDS), have also aired nationally. We examine the effects of recall of the truth© and TDS campaigns on changes in tobacco-related beliefs, intentions, and smoking initiation in a longitudinal survey of U.S. youth. Recall of truth© was associated with increased agreement with antismoking beliefs, decreased smoking intentions, and lower rates of smoking initiation. Recall of TDS was associated with increased intentions to smoke soon but was not significantly associated with tobacco beliefs or smoking initiation among youth overall.

description: We consider factor-graph-based soft self-iterative equalization in wireless multipath channels. Since factor graphs are able to characterize multipath channels to per-path level, the corresponding soft self-iterative equalizer possesses reduced computational complexity in sparse multipath channels. The performance of the considered self-iterative equalizer is analyzed in both single-antenna and multiple-antenna multipath channels. When factor graphs of multipath channels have no cycles or mild cycle conditions, the considered self-iterative equalizer can converge to optimum performance after a few iterations; but it may suffer local convergence in channels with severe cycle conditions.

description: Hurricane Leslie (2018) was a non-tropical system that lasted for a long time undergoing several transitions between tropical and extratropical states. Its trajectory was highly uncertain and difficult to predict. Here the extratropical transition of Leslie is simulated using the Model for Prediction Across Scales (MPAS) with two different sets of initial conditions (IC): the operational analysis of the Integrate Forecast System (IFS) and the Global Forecast System (GFS).
 Discrepancies in Leslie position are found in the IC patterns, and in the intensity and amplitude of the dorsal-trough system in which Leslie is found. Differences are identified both in the geopotential height at 300 hPa and the geopotential thickness. Potential temperature in the dynamic tropopause shows a broader, more intense trough displaced western when using the IC-IFS. The IC-IFS simulation shows lesser trajectory errors but wind speed overestimation than the IC-GFS one. The complex situation of the extratropical transition, where Leslie interacts with a trough, increases the uncertainty associated with the intensification process.
 The disparities observed in the simulations are attributed to inaccuracies in generating the ICs. Both ICs generate different atmospheric configurations when propagated in time. Results suggest that during an extratropical transition in a highly baroclinic atmosphere, the IFS model's data assimilation method produced a more precise analysis than GFS due to the greater number of observations assimilated by the IFS, the greater spatial resolution of the model and the continuous adjustment of the simulations with the field of observations.

description: Background: Usutu virus (USUV), a flavivirus belonging to the Japanese encephalitis serocomplex, was identified in South Africa in 1959 and reported for the first time in Europe in 2001. To date, full length genome sequences have been available only for the reference strain from South Africa and a single isolate from each of Austria, Hungary, and Italy.

Methods: We sequenced four USUV isolates from Senegal and the Central African Republic (CAR) between 1974 and 2007 and compared the sequence data to USUV strains from Austria, Hungary, Italy, and South Africa using a Bayesian Markov chain Monte Carlo method. We further clarified the taxonomic status of a USUV strain isolated in CAR in 1969 and proposed earlier as a subtype of USUV due to an asymetric serological cross-reactivity with USUV reference strain.

Results: A comparison of the four newly obtained USUV sequences with those from SouthAfrica_1959, Vienna_2001, Budapest_2005, and Italy_2009 revealed that they are all 96-99% and 99% similar at the nucleotide and amino acid levels, respectively. The phylogenetic relationships between these sequences indicated that a strain isolated in Senegal in 1993 is most closely related to the USUV strains detected in Europe. Analysis of a strain isolated from a human in CAR in 1981 (CAR_1981) revealed the presence of specific amino acid substitutions and a deletion in the 3′ noncoding region. This is the first fully sequenced human USUV isolate.
The putative USUV subtype, CAR_1969, was 81% and 94% identical at the nucleotide and amino acid levels, respectively, compared to the other USUV strains. Our phylogenetic analyses support the serological identification of CAR_1969 as a subtype of USUV.

Conclusions: In this study, we investigate the genetic diversity of USUV in Africa and the phylogenetic relationship of isolates from Africa and Europe for the first time. The results suggest a low genetic diversity within USUV, the existence of a distinct USUV subtype strain, and support the hypothesis that USUV was introduced to Europe from Africa. Further sequencing and analysis of USUV isolates from other African countries would contribute to a better understanding of its genetic diversity and geographic distribution.

description: We propose a new probabilistic numerical scheme for fully nonlinear equation of Hamilton-Jacobi-Bellman (HJB) type associated to stochastic control problem, which is based on the Feynman-Kac representation in [12] by means of control randomization and backward stochastic differential equation with nonpositive jumps. We study a discrete time approximation for the minimal solution to this class of BSDE when the time step goes to zero, which provides both an approximation for the value function and for an optimal control in feedback form. We obtained a convergence rate without any ellipticity condition on the controlled diffusion coefficient. Explicit implementable scheme based on Monte-Carlo simulations and empirical regressions, associated error analysis, and numerical experiments are performed in the companion paper [13].

description: Hot-isostatic pressing (HIPing) of powders is achieved by placing them inside a canister, which is then evacuated and sealed. Canister filling is a critical step. Consistency in powder packing in the canister and increases in packing density will improve process efficiency and the predictability of HIP canister collapse, leading to less wastage. Understanding the effect of powder morphology, properties and characteristics on the can filling process and subsequent compaction is vital to optimizing canister design and the filling system. Conventionally, this has involved conducting numerous costly and time-consuming trial-and-error experiments. Computational modelling offers an alternative optimization path. Discrete element method (DEM) simulation of a powder filling process has been developed by GRI Inc. and its application to the US Department of Energy’s radioactive Idaho calcine powders has been investigated. A comprehensive analysis of a non-radioactive simulant powder has been conducted. A DEM model was developed with validation of the model using experimental data obtained from the filling system development program.

description: Schwinger-Dyson equations are used to study the phase diagram of QED in three dimensions. This computation is made with full frequency-dependence in the two-point function gap equations for the first time. We also demonstrate that reliable results are attainable in spite of an infrared divergence that is endemic to the theory. A theoretically sound method for dealing with cutoff ultraviolet regulators is presented. Finally, it is shown that the quenched and instantaneous approximations often used in the literature are inaccurate.

description: Spontaneous transport barrier generation at the edge of a magnetically confined plasma is investigated. To this end, a model of electrostatic turbulence in three-dimensional geometry is extended to account for the impact of friction between trapped and passing particles on the radial electric field. Non-linear flux-driven simulations are carried out, and it is shown that considering the radial and temporal variations of the neoclassical friction coefficients allows for a transport barrier to be generated above a threshold of the input power.

description: On December 3 1984, more than 40 tons of methyl isocyanate gas leaked from a pesticide plant in Bhopal, India, immediately killing at least 3,800 people and causing significant morbidity and premature death for many thousands more. The company involved in what became the worst industrial accident in history immediately tried to dissociate itself from legal responsibility. Eventually it reached a settlement with the Indian Government through mediation of that country's Supreme Court and accepted moral responsibility. It paid $470 million in compensation, a relatively small amount of based on significant underestimations of the long-term health consequences of exposure and the number of people exposed. The disaster indicated a need for enforceable international standards for environmental safety, preventative strategies to avoid similar accidents and industrial disaster preparedness. Since the disaster, India has experienced rapid industrialization. While some positive changes in government policy and behavior of a few industries have taken place, major threats to the environment from rapid and poorly regulated industrial growth remain. Widespread environmental degradation with significant adverse human health consequences continues to occur throughout India.
