description: We present simultaneous $g'$, $R_{\rm c}$, and $I_{\rm c}$ photometry of the notable dwarf nova ER UMa during the 2011 season. Our photometry revealed that the brightness maxima of negative superhumps coincide with the bluest peaks in $g' - I_{\rm c}$ colour variations. We also found that the amplitudes of negative superhumps are the largest in the $g'$ band. These observed properties are significantly different from those observed in early and positive superhumps. Our findings are consistent with a tilted disk model as the light source of negative superhumps.

description: Point-vortex dynamics describe idealized, non-smooth solutions to the incompressible Euler equations on 2-dimensional manifolds. Integrability results for few point-vortices on various domains is a vivid topic, with many results and techniques scattered in the literature. Here we give a unified framework for proving integrability results for $N=2$, $3$, or $4$ point-vortices (and also more general Hamiltonian systems), based on symplectic reduction theory. The approach works on any 2-dimensional manifold; we illustrate it on the sphere, the plane, the hyperbolic plane, and the flat torus. A systematic study of integrability is prompted by advances in 2-dimensional turbulence, bridging the long-time behaviour of 2D Euler equations with questions of point-vortex integrability. A gallery of solutions is given in the appendix.

description: The effects of transmitter-side multidimensional signal rotations on the performance of multichannel optical transmission are studied in the presence of laser phase noise. In particular, the laser phase noise is assumed to be uncorrelated between channels. To carry out this study, a simple multichannel laser-phase-noise model that has been experimentally validated for weakly-coupled multicore-fiber transmission is considered. As the considered rotation scheme is intended to work in conjunction with receiver-side carrier phase estimation (CPE), the model is modified to further assume that imperfect CPE has taken place, leaving residual phase noise in the processed signal. Based on this model, two receiver structures are derived and used to numerically optimize transmitter-side signal rotations through Monte Carlo simulations. For reasonable amounts of residual phase noise, rotations based on Hadamard matrices are found to be near-optimal for transmission of four-dimensional signals. Furthermore, Hadamard rotations can be performed for any dimension that is a power of two. By exploiting this property, an increase of up to 0.25 bit per complex symbol in an achievable information rate is observed for transmission of higher-order constellations.

description: We present a high-quality X-ray spectrum in the 3--53 keV rest-frame band of the radio-loud quasar 1508+5714, by far the brightest known X-ray source at z > 4. A simple power-law model with an absorption column density equal to the Galactic value in the direction of the source provides an excellent and fully adequate fit to the data; the measured power-law photon index Gamma = 1.42 (+0.13,-0.10). Upper limits to Fe K alpha line emission and Compton-reflection components are derived. We offer evidence for both X-ray and radio variability in this object and provide the first contemporaneous radio spectrum (alpha = -0.25). The data are all consistent with a picture in which the emission from this source is dominated by a relativistically beamed component in both the X-ray and radio bands.

description: Joint-channel carrier-phase estimation can improve the performance of multichannel optical communication systems. In the case of pilot-aided estimation, the pilots are distributed over a two-dimensional channel--time symbol block that is transmitted through multiple channels. However, suboptimal pilot distributions reduce the effectiveness of the carrier-phase estimation and thus result in unnecessary pilot overhead, which reduces the overall information rate of the system. It is shown that placing pilots identically in all channels is suboptimal in general. By instead optimizing the pilot distribution, the mean squared error of the phase-noise estimates can be decreased by over 90% in some cases. Moreover, it is shown that the achievable information rate can be increased by up to 0.05, 0.16, and 0.41 bits per complex symbol for dual-polarization 20 GBd transmission of 64-ary, 256-ary, and 1024-ary quadrature amplitude modulation over 20 four-dimensional channels, respectively, assuming a total laser linewidth of 200 kHz.

description: Given a smooth projective toric variety $X$ of Picard rank 2, we resolve the diagonal sheaf on $X \times X$ by a linear complex of length $\dim{X}$ consisting of finite direct sums of line bundles. As applications, we prove a new case of a conjecture of Berkesch-Erman-Smith that predicts a version of Hilbert's Syzygy Theorem for virtual resolutions, and we obtain a Horrocks-type splitting criterion for vector bundles over smooth projective toric varieties of Picard rank 2, extending a result of Eisenbud-Erman-Schreyer. We also apply our results to give a new proof, in the case of smooth projective toric varieties of Picard rank 2, of a conjecture of Orlov concerning the Rouquier dimension of derived categories.

description: Electromagnetic response is studied for clusters of subwavelength graphene-coated nanowires illuminated by a linearly polarized plane wave in the terahertz frequency range. The solution of the scattering problem is obtained with the Lorenz-Mie theory and the multiple cylinder scattering formalism. The results show that normalized scattering cross-sections of nanowire clusters can be drastically changed by the symmetry breaking introduced into the cluster's design. This effect is due to excitation of dark modes and is observed only for the incident wave of TE-polarization.

description: The correspondence between the four-dimensional SU(N), $\cN = 4$ SYM taken at large $N$ and the type II B SUGRA on the $AdS_5\times S_5$ background is considered. We argue that the classical equations of motion in the SUGRA picture can be interpreted as that of the renormalization group on the SYM side. In fact, when the D3-brane is slightly excited higher derivative terms in the field theory on its world-volume deform it form the conformal $\cN = 4$ SYM limit. We give arguments in favor of that the deformation goes in the way set by the SUGRA equations of motion. Concrete example of the s-wave dilaton is considered.

title: Trends in Civic Engagement in Australia
Creators: name: Cameron, Sarah
Publisher: name: The Australian National University
Year: 2025

description: A longstanding debate concerns whether civic engagement is in decline in the advanced democracies and whether this forms part of a crisis of democracy. This paper situates Australia within this debate by providing a broad overview of the state of civic engagement in Australia. To do so, this paper analyses data from the World Values Survey with a focus on voluntary association memberships. The results show that civic engagement in Australia is high in comparison to other democracies around the world. Although civic engagement is relatively high, it has declined to some degree over the past few decades. There is considerable variation in who participates in civic life, with the university-educated and those on higher incomes more likely to be members of associations. This suggests that the benefits of civic engagement are not distributed evenly across the population. Ongoing data collection is needed to continue to track Australia’s civic engagement over time, in comparison to other countries, and across different indicators of engagement.

description: The Millennium Project, an international participatory think tank that uses futures research to systematically explore, create and test both possible and desirable futures in order to improve decisions in the present, presents unprecedented challenges for Australian education. Their publication, 2015-16 State of the Future, outlines 15 global challenges that represent an unparalleled invitation for educators to think creatively and imaginatively to design experiences whereby students successfully engage in ‘border crossing’ (Giroux, 1992). The act of border crossing provides unprecedented opportunities for children, young people and adults to develop intercultural competencies and skills that better enable them to live together mindfully. We present a new border pedagogy based on the concept of hybridity that works to build students’ and citizens’ intercultural competence by encouraging them to embrace potential miscommunication and intercultural conflict. By learning how to embracing hybridity, students can work productively to put what is known into crisis by constantly blurring and problematising boundaries, binaries and identities. Our new border pedagogy promotes living ‘together-in-difference’ (Ang, 2001) by encouraging students to critically interrogate issues of difference they face as they border cross. The border pedagogy for living together-in-difference encourages students to embrace intercultural conflict and potential miscommunication because of the questions and wonderings it kindles and inspires. Importantly, it presents a pedagogy that assists educators in building on the educational goals of the Melbourne Declaration and engaging effectively with the Australian Curriculum’s cross-curriculum priorities so students can prosper individually, collectively and communally in a globalised world.

description: Approaching Shannon's capacity via geometric shaping has usually been regarded as challenging due to modulation and demodulation complexity, requiring look-up tables to store the constellation points and constellation bit labeling. To overcome these challenges, in this paper, we study lattice-based geometrically shaped modulation formats in multidimensional Euclidean space. We describe and evaluate fast and low complexity modulation and demodulation algorithms that make these modulation formats practical, even with extremely high constellation sizes with more than $10^{28}$ points. The uncoded bit error rate performance of these constellations is compared with the conventional QAM formats in the additive white Gaussian noise and nonlinear fiber channels. At a spectral efficiency of 2 bits/sym/polarization, compared with 4-QAM format, transmission reach improvement of more than 38% is shown at the hard-decision forward error correction threshold of $2.26\times 10^{-4}$.

The associated dissipative effects may explain orders of magnitude differences between the predictions of the ordinary RWA model and results from recent superconducting circuits experiments on the Kerr-cat qubit. The higher-order dissipators found in our calculations have important consequences for quantum error-correction protocols and parametric processses.

description: The study region of Izmir and its surroundings is known for the unique and rich physical geography and environmental settings. The physical geography of the region combines diverse landforms, various geomorphological and natural landscapes, species and vegetation richness. The geomorphological settings of the area include wide variety of landforms, including mountains landscapes, caves, islands in the coastal area, waterfalls, lakes, etc. The geology of the area of Western Anatolia is characterized by the neotectonic active faulting and high seismicity, which leads to geomorphological instabilities and landslide formation in the research area. At the same time, the region is being intensively visited by the tourists, due to its natural attractiveness, favorable climatic conditions, scenic landscapes and cultural richness. The development of the tourism covers both traditional coastal areas and geothermal hot water springs. Besides recreation activities, the region is known for its intensive agricultural cultivation, such as producing olive trees, cultivating fruits. Finally, being a large metropolis of Turkey, Izmir is an important industrial city, a key seaport in the transportation network in the Mediterranean, and a country’s business center. All these factors cause strong anthropogenic pressure on the environment in the study region of Izmir. Therefore, the purpose of this research is to analyze, how the environmental settings and landscapes in Izmir province changed over the past decades.
A MASTER FORMULA FOR CHIRAL SYMMETRY BREAKING

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We derive a master formula for chiral $SU(2)\times SU(2)$ breaking, based on the Veltman-Bell equations and the Peierls-Dyson relation. Our approach does not rely on the use of the soft pion limit or an expansion around the chiral limit, and yields exact results for on-shell pions. Threshold theorems for $πN\rightarrow πN$, $γN\rightarrow πN$, $πN\rightarrowππN$, $γN\rightarrow γπN$, $γN\rightarrow ππN$ and $πN\rightarrow πγN$ are recovered, and corrections to them are given. The reactions $π\rightarrow eνγ$, $π\rightarrow eνe^+e^-$, $γπ\rightarrow γπ$ and $γγ\rightarrow ππ$ are also discussed. A general formula for $ππ$ scattering and a new one loop effective action are obtained. The new effective action reproduces the KSFR relation, and yields specific estimates for the pion polarisabilities. A detailed comparison with baryon-free chiral perturbation theory to one loop is made. An extension of our effective action to two loops is outlined.

description: A fast charged particle crossing the boundary between the chiral matter and vacuum radiates the transition radiation. Its most remarkable features --- the resonant behavior at a certain emission angle and the circular polarization of the spectrum --- depend on the parameters of the chiral anomaly in a particular material/matter. The chiral transition radiation can be used to investigate the chiral anomaly in such diverse media as the quark-gluon plasma, the Weyl semimetals, and the axionic dark matter.

description: In this paper, we present two constructions of quantum locally testable codes (QLTC) with constant soundness. In the first approach, we introduce an operation called check product, and show how this operation gives rise to QLTCs of constant soundness, constant rate, and distance scaling with locality. In the second approach, we consider hypergraph product of a quantum code and a classical repetition code, and observe a special case in which the soundness of component codes is preserved. This insight leads us to construct QLTCs of constant soundness, scalable rate and distance, and constant average locality. Our work marks a step towards constructing QLTCs of high soundness and distance, which would give a different construction to the No Low-Energy Trivial States (NLTS) theorem.

description: Coherent optical transmission systems naturally lead to a four dimensional (4D) signal space, i.e., two polarizations each with two quadratures. In this paper we derive an analytical model to quantify the impact of Kerr nonlinearity on such 4Dspaces, taking the interpolarization dependency into account. This is in contrast to previous models such as the GN and EGN models, which are valid for polarization multiplexed (PM)formats, where the two polarizations are seen as independent channels on which data is multiplexed. The proposed model agrees with the EGN model in the special case of independent two-dimensional modulation in each polarization. The model accounts for the predominant nonlinear terms in a WDM system, namely self-phase modulation and and cross-phase modulation. Numerical results show that the EGN model may inaccurately estimate the nonlinear interference of 4D formats. This nonlinear interference discrepancy between the results of the proposed model and the EGN model could be up to 2.8 dB for a system with 80 WDM channels. The derived model is validated by split-step Fourier simulations, and it is shown to follow simulations very closely.

description: This paper studies the endemic behavior of a multi-competitive networked susceptible-infected-susceptible (SIS) model. In particular, we focus on the case where there are three competing viruses (i.e., the tri-virus system). First, we show that the tri-virus system is not a monotone system. Thereafter, we provide a condition that guarantees local exponential convergence to a boundary equilibrium (exactly one virus is endemic, the other two are dead), and identify a special case that admits the existence and local exponential attractivity of a line of coexistence equilibria (at least two viruses are active). Finally, we identify a particular case (subsumed by the aforementioned special case) such that, for all nonzero initial infection levels, the dynamics of the tri-virus system converge to a plane of coexistence equilibria.

Conservation of asymptotic charges from past to future null infinity: Maxwell fields

description: On any asymptotically-flat spacetime, we show that the asymptotic symmetries and charges of Maxwell fields on past null infinity can be related to those on future null infinity as recently proposed by Strominger. We extend the covariant formalism of Ashtekar and Hansen by constructing a 3-manifold of both null and spatial directions of approach to spatial infinity. This allows us to systematically impose appropriate regularity conditions on the Maxwell fields near spatial infinity along null directions. The Maxwell equations on this 3-manifold and the regularity conditions imply that the relevant field quantities on past null infinity are antipodally matched to those on future null infinity. Imposing the condition that in a scattering process the total flux of charges through spatial infinity vanishes, we isolate the subalgebra of totally fluxless symmetries near spatial infinity. This subalgebra provides a natural isomorphism between the asymptotic symmetry algebras on past and future null infinity, such that the corresponding charges are equal near spatial infinity. This proves that the flux of charges is conserved from past to future null infinity in a classical scattering process of Maxwell fields. We also comment on possible extensions of our method to scattering in general relativity.

Canonical scale separation in two-dimensional incompressible hydrodynamics

description: A two-dimensional inviscid incompressible fluid is governed by simple rules. Yet, to characterise its long-time behaviour is a knotty problem. The fluid evolves according to Euler's equations: a non-linear Hamiltonian system with infinitely many conservation laws. In both experiments and numerical simulations, coherent vortex structures, or blobs, emerge after an initial stage. These formations dominate the large-scale dynamics, but small scales also persist. Kraichnan describes in his classical work a forward cascade of enstrophy into smaller scales, and a backward cascade of energy into larger scales. Previous attempts to model Kraichnan's double cascade use filtering techniques that enforce separation from the outset. Here we show that Euler's equations posses an intrinsic, canonical splitting of the vorticity function. The splitting is remarkable in four ways: (i) it is defined solely via the Poisson bracket and the Hamiltonian, (ii) it characterises steady flows, (iii) without imposition it yields a separation of scales, enabling the dynamics behind Kraichnan's qualitative description, and (iv) it accounts for the "broken line" in the power law for the energy spectrum, observed in both experiments and numerical simulations. The splitting originates from Zeitlin's truncated model of Euler's equations in combination with a standard quantum-tool: the spectral decomposition of Hermitian matrices. In addition to theoretical insight, the scale separation dynamics could be used for stochastic model reduction, where small scales are modelled by multiplicative noise.

Density decay and growth of correlations in the Game of Life

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We study the Game of Life as a statistical system on an $L\times L$ square lattice with periodic boundary conditions. Starting from a random initial configuration of density $ρ_{\rm in}=0.3$ we investigate the relaxation of the density as well as the growth with time of spatial correlations. The asymptotic density relaxation is exponential with a characteristic time $τ_L$ whose system size dependence follows a power law $τ_L\propto L^z$ with $z=1.66\pm 0.05$ before saturating at large system sizes to a constant $τ_\infty$. The correlation growth is characterized by a time dependent correlation length $ξ_t$ that follows a power law $ξ_t\propto t^{1/z^\prime}$ with $z^\prime$ close to $z$ before saturating at large times to a constant $ξ_\infty$. We discuss the difficulty of determining the correlation length $ξ_\infty$ in the final "quiescent" state of the system. The decay time $t_{\rm q}$ towards the quiescent state is a random variable, we present simulational evidence as well as a heuristic argument indicating that for large $L$ its distribution peaks at a value $t_{\rm q}^*(L) \simeq 2τ_\infty\log L$.

A New Border Pedagogy: Rethinking Outbound Mobility Programs in the Asian Century

description: Australian universities have implemented outbound student mobility programs focused on the Asian region and hyped them as a ‘powerful' educational strategy with the potential to positively transform students through opportunities to acquire intercultural competence. It is assumed students' intercultural competence will give them ‘the edge' they need to be successful when working with cultural others across diverse contexts. While outbound mobility programs can build students' intercultural competence, this does not happen just because they study abroad. This chapter presents a new border pedagogy based on the concept of hybridity that is being used to transform an Australian outbound mobility program. The new border pedagogy works by intentionally putting what is ‘known' into crisis by constantly blurring and problematising boundaries, binaries and identities. Outbound mobility programs that leverage a new border pedagogy underpinned by hybridity can build students' intercultural competence by encouraging them to embrace potential miscommunication and intercultural conflict.

description: Probabilistic shaping (PS) has been widely studied and applied to optical fiber communications. The encoder of PS expends the number of bit slots and controls the probability distribution of channel input symbols. Not only studies focused on PS but also most works on optical fiber communications have assumed source uniformity (i.e. equal probability of marks and spaces) so far. On the other hand, the source information is in general nonuniform, unless bit-scrambling or other source coding techniques to balance the bit probability is performed. Interestingly, one can exploit the source nonuniformity to reduce the entropy of the channel input symbols with the PS encoder, which leads to smaller required signal-to-noise ratio at a given input logic rate. This benefit is equivalent to a combination of data compression and PS, and thus we call this technique compressed shaping. In this work, we explain its theoretical background in detail, and verify the concept by both numerical simulation and a field programmable gate array (FPGA) implementation of such a system. In particular, we find that compressed shaping can reduce power consumption in forward error correction decoding by up to 90% in nonuniform source cases. The additional hardware resources required for compressed shaping are not significant compared with forward error correction coding, and an error insertion test is successfully demonstrated with the FPGA.

Towards Maximising Intercultural Learning for Australian University Students in an English-Speaking Study Abroad Program in Malaysia

description: The current political, institutional and global influences impacting on Australian university students' participation in study abroad is largely under researched. In distinguishing between study abroad for linguistic gain and for non-language learning purposes, I highlight that the linguistic context in study abroad research is generally unexplored, yet timely and relevant. I report on exploratory research conducted with Australian undergraduate Commerce students embarking on a compulsory study abroad experience to Malaysia. Data collected were analysed from a theoretical framework that includes both identity orientations and the Process Model of Intercultural Competence. With Australia's closest regional neighbours embracing internationalisation of education, and thus the English language, I argue that further knowledge of students and their study abroad experiences in such destinations has implications for the design and implementation of study abroad programs. Without this knowledge, universities may not be able to provide sufficient support, through student mobility, for students to become truly interculturally competent.
