description: We identify velocity channel map intensities as a new way to trace magnetic fields in turbulent media. This work makes use of both of the modern theory of MHD turbulence predicting that the magnetic eddies are aligned with the local direction of magnetic field, and also the theory of the spectral line Position-Position-Velocity (PPV) statistics describing how the velocity and density fluctuations are mapped into the PPV space. In particular, we use the fact that, the fluctuations of intensity of thin channel maps are mostly affected by the turbulent velocity, while the thick maps are dominated by density variations. We study how contributions of the fundamental MHD modes affect the Velocity Channel Gradients (VChGs) and demonstrate that the VChGs arising from Alfven and slow modes are aligned perpendicular to the local direction of magnetic field, while the VChGs produced by the fast mode are aligned parallel to the magnetic field. The dominance of the Alfven and slow modes in the interstellar media will therefore allow a reliable magnetic field tracing using the VChGs. We explore ways of identifying self-gravitating regions that do not require polarimetric information. In addition, we also introduce a new measure termed "Reduced Velocity Centroids" (RVCGs) and compare its abilities with the VChGs. We employed both measures to the GALFA 21cm data and successfully compared thus magnetic field directions with the {\it PLANCK} polarization. The applications of the suggested techniques include both tracing magnetic field in diffuse interstellar media and star forming regions, as well as removing the galactic foreground in the framework of cosmological polarization studies.

description: We study the ellipticity of galaxy cluster halos as characterized by the distribution of cluster galaxies and as measured with weak lensing. We use monte-carlo simulations of elliptical cluster density profiles to estimate and correct for Poisson noise bias, edge bias and projection effects. We apply our methodology to 10,428 SDSS clusters identified by the redMaPPer algorithm with richness above 20. We find a mean ellipticity $= 0.271 \pm 0.002$ (stat) $\pm 0.031$ (sys) corresponding to an axis ratio $= 0.573 \pm 0.002$ (stat) $\pm 0.039$ (sys). We compare this ellipticity of the satellites to the halo shape, through a stacked lensing measurement using optimal estimators of the lensing quadrupole based on Clampitt and Jain (2016). We find a best-fit axis ratio of $0.56 \pm 0.09$ (stat) $\pm 0.03$ (sys), consistent with the ellipticity of the satellite distribution. Thus cluster galaxies trace the shape of the dark matter halo to within our estimated uncertainties. Finally, we restack the satellite and lensing ellipticity measurements along the major axis of the cluster central galaxy's light distribution. From the lensing measurements we infer a misalignment angle with an RMS of ${30^\circ \pm 10}^\circ$ when stacking on the central galaxy. We discuss applications of halo shape measurements to test the effects of the baryonic gas and AGN feedback, as well as dark matter and gravity. The major improvements in signal-to-noise expected with the ongoing Dark Energy Survey and future surveys from LSST, Euclid and WFIRST will make halo shapes a useful probe of these effects.

description: We would like to put the area law -- believed to by obeyed by entanglement entropies in the ground state of a local field theory -- to scrutiny in the presence of non-perturbative effects. We study instanton corrections to entanglement entropy in various models whose instanton effects are well understood, including $U(1)$ gauge theory in 2+1 dimensions and false vacuum decay in $ϕ^4$ theory, and we demonstrate that the area law is indeed obeyed in these models. We also perform numerical computations for toy wavefunctions mimicking the theta vacuum of the (1+1)-dimensional Schwinger model. Our results indicate that such superpositions exhibit no more violation of the area law than the logarithmic behavior of a single Fermi surface.

description: We study mass and population imbalance effect on density (in-phase) and spin (out-of-phase) collective modes in a two-component normal Fermi gas. By calculating eigenmodes of the linearized Boltzmann equation as well as the density/spin dynamic structure factor, we show that mass and population imbalance effects offer a variety of collective mode crossover behaviors from collisionless to hydrodynamic regimes. The mass imbalance effect shifts the crossover regime to the higher-temperature, and a significant peak of the spin dynamic structure factor emerges only in the collisionless regime. This is in contrast to the case of mass and population balanced normal Fermi gases, where the spin dynamic response is always absent. Although the population imbalance effect does not shift the crossover regime, the spin dynamic structure factor survives both in the collisionless and hydrodynamic regimes.

A New Bayesian Approach to Robustness Against Outliers in Linear Regression

description: Linear regression is ubiquitous in statistical analysis. It is well understood that conflicting sources of information may contaminate the inference when the classical normality of errors is assumed. The contamination caused by the light normal tails follows from an undesirable effect: the posterior concentrates in an area in between the different sources with a large enough scaling to incorporate them all. The theory of conflict resolution in Bayesian statistics (O'Hagan and Pericchi (2012)) recommends to address this problem by limiting the impact of outliers to obtain conclusions consistent with the bulk of the data. In this paper, we propose a model with super heavy-tailed errors to achieve this. We prove that it is wholly robust, meaning that the impact of outliers gradually vanishes as they move further and further away form the general trend. The super heavy-tailed density is similar to the normal outside of the tails, which gives rise to an efficient estimation procedure. In addition, estimates are easily computed. This is highlighted via a detailed user guide, where all steps are explained through a simulated case study. The performance is shown using simulation. All required code is given.

description: We study degenerations of Bethe subalgebras $B(C)$ in the Yangian $Y(\mathfrak{gl}_n)$, where $C$ is a regular diagonal matrix. We show that closure of the parameter space of the family of Bethe subalgebras, which parametrizes all possible degenerations, is the Deligne-Mumford moduli space of stable rational curves $\overline{M_{0,n+2}}$. All subalgebras corresponding to the points of $\overline{M_{0,n+2}}$ are free and maximal commutative. We describe explicitly the "simplest" degenerations and show that every degeneration is the composition of the simplest ones. The Deligne-Mumford space $\overline{M_{0,n+2}}$ generalizes to other root systems as some De Concini-Procesi resolution of some toric variety. We state a conjecture generalizing our results to Bethe subalgebras in the Yangian of arbitrary simple Lie algebra in terms of this De Concini-Procesi resolution.

Uniform Transition Tree-Structured Critically Sampled Filterbanks

Subjects: subject: Electrical engineering
subject: Signal processing

subject: Audio coding

description: Critically sampled filterbanks are useful in applications like audio coding that involve processing the time-varying spectral characteristics of signals. Critically sampled filterbanks can be implemented with a tree-structure. The odd-numbered subbands of a critically sampled filterbank exhibit frequency inversion, causing subbands to be unordered in frequency past the first layer. We show how subbands can be swapped at each layer to maintain their ordering. Self-similar filterbanks, using the same filters at each layer of the tree, have nonuniform transition widths and long impulse responses. We explore using filters with wider transition widths at deeper layers, and we demonstrate that this technique can be used to implement an efficient uniform transition filterbank. We compare this uniform transition filterbank with a self-similar filterbank in an audio codec, showing that the uniform transition filterbank achieves a smaller maximum transition width at a lower impulse response length.

description: We present a systematic introduction to the diagrammatic method for practical calculations in inflationary cosmology, based on Schwinger-Keldysh path integral formalism. We show in particular that the diagrammatic rules can be derived directly from a classical Lagrangian even in the presence of derivative couplings. Furthermore, we use quasi-single-field inflation as an example to show how this formalism, combined with the trick of mixed propagator, can significantly simplify the calculation of some in-in correlation functions. The resulting bispectrum includes the lighter scalar case ($m<3H/2$) that has been previously studied, and the heavier scalar case ($m>3H/2$) that has not been explicitly computed for this model. The latter provides a concrete example of quantum primordial standard clocks, in which the clock signals can be observably large.

title: Communication and reproductive behaviour of the Bermuda White-eyed Vireo (Vireo griseus bermudianus) and other vireonids
Creators: name: Mejias, Miguel Alberto
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: Vocal displays are one of the primary ways songbirds communicate. The drivers of bird song diversity, how it might promote speciation through reproductive isolation, and their role in mate attraction and territory defence, can be better understood by studying variation within avian families. I studied the structure and function of songs in Vireonidae, and the nesting and singing behaviour of the Bermuda White-eyed Vireo (Vireo griseus bermudianus). I found that Vireonidae song traits have phylogenetic signal, with song traits being more similar among closer relatives than among distant relatives. I also found that species with smaller bodies and bills produced higher peak frequencies than bigger species. Using song playback, I tested whether male Bermuda Vireos, which are allopatric to all other vireonids, perceive this song diversity and adjust their response strength according to acoustic similarity that is related to phylogenetic history. Bermuda Vireos exhibited more vocalizations and speaker interactions during playbacks of closer relatives versus distant relatives, and to songs with more acoustic similarity to Bermuda Vireos. After studying their nesting cycle, I learned that breeding pairs in this subspecies sometimes remain paired for at least four years, and that they build small, cup-shaped nests in native and introduced trees. During February – September, both sexes performed nest building (N = 13, 5 ± 3 days; mean ± SD), incubation (11, 14 ± 2 days), nestling care (6, 11 ± 2 days), and fledgling care (5, 41 ± 12 days). Nest predation from introduced predators caused most nest failures. I then quantified their song rates during these nesting stages to understand how song functions in mate attraction, territory defence, and nest predator avoidance. Despite singing year-round, males during the breeding season without nesting duties sang more than males with nesting duties. Males sang less during the nestling stage, when predation was highest. Song perch height was higher during the breeding season than the non-breeding season, among males without nesting duties compared to males with nesting duties, and when males produced discrete songs rather than rambling songs. My doctoral thesis sheds light on factors shaping bird song structure, how receivers perceive these signals, and how males use them to communicate their breeding status and territory ownership.

description: In this paper we study some conditional probabilities for the totally asymmetric simple exclusion processes (TASEP) with second class particles. To be more specific, we consider a finite system with one first class particle and $N-1$ second class particles, and we assume that the first class particle is initially at the leftmost position. In this case, we find the probability that the first class particle is at $x$ and it is still the leftmost particle at time $t$. In particular, we show that this probability is expressed by the determinant of an $N\times N$ matrix of contour integrals if the initial positions of particles satisfy the step initial condition. The resulting formula is very similar to a known formula in the (usual) TASEP with the step initial condition which was used for asymptotics by Nagao and Sasamoto [Nuclear Phys. B 699 (2004), 487-502].

description: We present a method for detecting electromagnetic (EM) modes that couple to a superconducting qubit in a circuit-QED architecture. Based on measurement-induced dephasing, this technique allows the measurement of modes that have a high quality factor (Q) and may be difficult to detect through standard transmission and reflection measurements at the device ports. In this scheme the qubit itself acts as a sensitive phase meter, revealing modes that couple to it through measurements of its coherence time. Such modes are indistinguishable from EM modes that do not couple to the qubit using a vector network analyzer. Moreover, this technique provides useful characterization parameters including the quality factor and the coupling strength of the unwanted resonances. We demonstrate the method for detecting both high-Q coupling resonators in planar devices as well as spurious modes produced by a 3D cavity.

title: Interprofessional learning and rural paramedic practice
Creators: name: Mulholland, PF
Publisher: name: University of Tasmania
Year: 2020

description: There is a long history of collaboration between paramedics and other health care workers; yet little is known about the various ways in which paramedics and different health care professionals interact and convey meaning about an interprofessional approach. Accordingly, this study investigates interprofessional learning involving rural paramedic practice. Interprofessional learning is a process of integration and synthesis of knowledge between two or more professions, in order to solve problems or explore issues around patient care. Set across eight rural locations in the state of Tasmania, Australia, this study is an in-depth investigation of interprofessional learning amongst rural paramedics. A constructivist grounded theory (Charmaz, 2006) methodology was employed. Semi-structured interviews based on Critical Incident technique (CIT) were conducted with twenty-six participants, including paramedics, ambulance volunteers and other qualified health professionals. Data were analysed concurrently with, and informed, data generation, progressing through the cycles of initial, focused and theoretical coding based on emerging concepts. Three main concepts around interprofessional learning and rural paramedic practice were identified: relationships, cooperation and operational barriers. These findings led to the development of A theory of interprofessional learning and rural paramedic practice, that provides insight to the contexts and processes of interprofessional learning and paramedic practice in a rural setting. Implications for practice stem from the recognition that in rural health care settings, informal collaboration between paramedics and other health care workers enhances interprofessional learning and contributes to improved patient care. By adopting a proactive and strategic approach, which recognises the importance of these relationships, education providers can introduce programs that support the interprofessional nature of rural practice for paramedics, at both undergraduate and postgraduate level. Ambulance services can identify operational barriers to interprofessional practice and develop ways to eliminate these or minimise their impact. A limitation of the study was that data were specific to paramedic practice in selected rural settings of Tasmania. Opportunities exist for further investigation outside of Tasmania with larger samples and in other settings, including urban locations and using different methodologies. Further research should be conducted into the policy framework required to enable collaborative practice between different professionals; the processes involved in establishing relationships and cooperation among healthcare providers; and interprofessional differences between models of paramedic practice.

description: In deep tissue photoacoustic imaging the spatial resolution is inherently limited by the acoustic wavelength. Recently, it was demonstrated that it is possible to surpass the acoustic diffraction limit by analyzing fluctuations in a set of photoacoustic images obtained under unknown speckle illumination patterns. Here, we purpose an approach to boost reconstruction fidelity and resolution, while reducing the number of acquired images by utilizing a compressed sensing computational reconstruction framework. The approach takes into account prior knowledge of the system response and sparsity of the target structure. We provide proof of principle experiments of the approach and demonstrate that improved performance is obtained when both speckle fluctuations and object priors are used. We numerically study the expected performance as a function of the measurements signal to noise ratio and sample spatial-sparsity. The presented reconstruction framework can be applied to analyze existing photoacoustic experimental datasets containing dynamic fluctuations.

Charge versus energy transfer in atomically-thin graphene-transition metal dichalcogenide van der Waals heterostructures

description: Van der Waals heterostuctures, made from stacks of two-dimensional materials, exhibit unique light-matter interactions and are promising for novel optoelectronic devices. The performance of such devices is governed by near-field coupling through, e.g., interlayer charge and/or energy transfer. New concepts and experimental methodologies are needed to properly describe two-dimensional heterointerfaces. Here, we report on interlayer charge and energy transfer in atomically thin metal (graphene)/semiconductor (transition metal dichalcogenide (TMD, here MoSe$_2$)) heterostructures using a combination of photoluminescence and Raman scattering spectroscopies. The photoluminescence intensity in graphene/MoSe$_2$ is quenched by more than two orders of magnitude and rises linearly with the photon flux, demonstrating a drastically shortened ($\sim 1~\tr{ps}$) room temperature MoSe$_2$ exciton lifetime. Key complementary insights are provided from analysis of the graphene and MoSe$_2$ Raman modes, which reveals net photoinduced electron transfer from MoSe$_2$ to graphene and hole accumulation in MoSe$_2$. Remarkably, the steady state Fermi energy of graphene saturates at $290\pm 15~\tr{meV}$ above the Dirac point. This behavior is observed both in ambient air and in vacuum and is discussed in terms of band offsets and environmental effects. In this saturation regime, balanced photoinduced flows of electrons and holes may transfer to graphene, a mechanism that effectively leads to energy transfer. Using a broad range of photon fluxes and diverse environmental conditions, we find that the presence of net photoinduced charge transfer has no measurable impact on the near-unity photoluminescence quenching efficiency in graphene/MoSe$_2$. This absence of correlation strongly suggests that energy transfer to graphene is the dominant interlayer coupling mechanism between atomically-thin TMDs and graphene.

title: Parties and the comic novel in interwar Britain
Creators: name: Murphy, E
Publisher: name: University of Tasmania
Year: 2020

description: Parties feature centrally in British interwar novels. Frequent references to and accounts of parties are used by writers in these works to express concerns about the self and its relationship with society in the early twentieth century. Shifting social and economic relations, combined with the aftermath of the First World War and the growth of leisure, gave rise to a body of literature that examined parties in detail. In particular, this thesis argues, the comic mode’s inherent concern with the social—through its observation and policing of human behaviour through laughter—made it an ideal vehicle for interwar writers to consider the party.While Mikhail Bakhtin’s theory of carnival is the most influential theory used in scholarly examinations of festivity in literature, this thesis contends that Bakhtin’s account cannot fully characterise the divergent representations of the party between the wars. The thesis instead offers a study of the modern party that identifies and examines its people, places, and things. By analysing the elements that constitute parties and their interrelation—such as hosts and guests, clothing and appearance, food and drink, location and décor—this thesis yields new knowledge about how writers perceived the evolution of sociability during a period of increased mobility and change.In order to situate the deployment and representation of parties, the thesis reads exemplary fictional texts in tandem with a collection of interwar nonfiction texts, including fashion periodicals, newspapers, cookbooks, and etiquette guides. This approach, grounded in cultural history, explores the socially and culturally loaded meanings of the structuring components of interwar festivity, locating the novels within the contexts in which they were first written, published, and read.The thesis examines a selection of novels by four British writers of comedy: Evelyn Waugh, Stella Gibbons, Nancy Mitford, and E. F. Benson. It offers close readings of how each writer responded to the party in their work. In Waugh’s novels, he positions the relationship between host and guest as the central logic that governs a party’s coherency: without it, sociability descends into chaos. For Gibbons, parties contain transformative and aspirational potential, operating as sites of social mobility for both her heroines and middlebrow readers alike. Mitford’s focus on specialty festive occasions such as Christmas reveals how the aristocracy use parties to reaffirm ideas of tradition, Englishness, and nationalism—a type of nostalgia that Mitford comically deflates as bathetic. Benson’s Mapp and Lucia series, meanwhile, critiques the rigidity of performances at parties through the repetitive narrative structures inherent to the novel series as a form. When taken together, the texts analysed in this thesis reveal the live tensions in interwar British sociability between tradition and modernity.

description: Poisson Voronoi tessellations have been used in modeling many types of systems across different sciences, from geography and astronomy to telecommunications. The existing literature on the statistical properties of Poisson Voronoi cells is vast, however, little is known about the properties of Voronoi cells located close to the boundaries of a compact domain. In a domain with boundaries, some Voronoi cells would be naturally clipped by the boundary, and the cell area falling inside the deployment domain would have different statistical properties as compared to those of non-clipped Voronoi cells located in the bulk of the domain. In this paper, we consider the planar Voronoi tessellation induced by a homogeneous Poisson point process of intensity $λ\!>\!0$ in a quadrant, where the two half-axes represent boundaries. We show that the mean cell area is less than $λ^{-1}$ when the seed is located exactly at the boundary, and it can be larger than $λ^{-1}$ when the seed lies close to the boundary. In addition, we calculate the second moment of cell area at two locations for the seed: (i) at the corner of a quadrant, and (ii) at the boundary of the half-plane. We illustrate that the two-parameter Gamma distribution, with location-dependent parameters calculated using the method of moments, can be of use in approximating the distribution of cell area. As a potential application, we use the Gamma approximations to study the degree distribution for secure connectivity in wireless sensor networks deployed over a domain with boundaries.

description: Hot, Dust-Obscured Galaxies, or "Hot DOGs", are a rare, dusty, hyperluminous galaxy population discovered by the WISE mission. Predominantly at redshifts 2-3, they include the most luminous known galaxies in the universe. Their high luminosities likely come from accretion onto highly obscured super massive black holes (SMBHs). We have conducted a pilot survey to measure the SMBH masses of five z~2 Hot DOGs via broad H_alpha emission lines, using Keck/MOSFIRE and Gemini/FLAMINGOS-2. We detect broad H_alpha emission in all five Hot DOGs. We find substantial corresponding SMBH masses for these Hot DOGs (~ 10^{9} M_sun), and their derived Eddington ratios are close to unity. These z~2 Hot DOGs are the most luminous AGNs at given BH masses, suggesting they are accreting at the maximum rates for their BHs. A similar property is found for known z~6 quasars. Our results are consistent with scenarios in which Hot DOGs represent a transitional, high-accretion phase between obscured and unobscured quasars. Hot DOGs may mark a special evolutionary stage before the red quasar and optical quasar phases, and they may be present at other cosmic epochs.

Hölder regularity of the 2D dual semigeostrophic equations via analysis of linearized Monge-Ampère equations

description: We obtain the Hölder regularity of time derivative of solutions to the dual semigeostrophic equations in two dimensions when the initial potential density is bounded away from zero and infinity. Our main tool is an interior Hölder estimate in two dimensions for an inhomogeneous linearized Monge-Ampère equation with right hand side being the divergence of a bounded vector field. As a further application of our Hölder estimate, we prove the Hölder regularity of the polar factorization for time-dependent maps in two dimensions with densities bounded away from zero and infinity. Our applications improve previous work by G. Loeper who considered the cases of densities sufficiently close to a positive constant.

title: Nanoparticle and cell modifications using capillary electrophoresis
Creators: name: Alves, MN
Publisher: name: University of Tasmania

description: Particle separation and manipulation is a strength of electrophoresis. In this dissertation, firstly, the power of electrophoresis as a microanalytical technique is demonstrated by separations of bare magnetic nanoparticles provided for the first time electropherograms exhibiting symmetrical and highly reproducible peaks, free of spurious spikes characteristic of nanoparticle clusters. This was achieved using non-complexing (nitrate) and complexing (chloride, citrate and phosphate) electrolyte ions with additions of tetramethylammonium hydroxide. This enabled the separation of bare and functionalised magnetic nanoparticles. Secondly, CE was coupled to a magnetic field and trapping of magnetic nanoparticles was demonstrated using purposely selected electrolyte compositions. Just like nanoparticles, cells exhibit an electric surface charge due to exposed charged or chargeable functional groups. Therefore, they migrate under the influence of an electric field. Through isotachophoretic focusing, the electrostatic adsorption of functionalised magnetic nanoparticles to the cell wall of Escherichia coli TOP10 and their cellular uptake was studied. The same strategy was applied for the ITP transformation of E. coli TOP10 with plasmid DNA. Counter pressure-assisted isotachophoresis brought a large excess of plasmid DNA in contact with the cell surface allowing for a transformation rate 1,000-fold higher compared to electroporation and chemical transfection at survival rates greater than 60%. Based on the findings, the ITP method was adjusted for effective transfection of mammalian cells (Jurkat T) showing similar robustness to electroporation. This opens possibilities of using the developed method for the delivery of many other membrane impermeable solutes for screening of genes and drugs.

Rigidity for von Neumann algebras given by locally compact groups and their crossed products

description: We prove the first rigidity and classification theorems for crossed product von Neumann algebras given by actions of non-discrete, locally compact groups. We prove that for arbitrary free probability measure preserving actions of connected simple Lie groups of real rank one, the crossed product has a unique Cartan subalgebra up to unitary conjugacy. We then deduce a W* strong rigidity theorem for irreducible actions of products of such groups. More generally, our results hold for products of locally compact groups that are nonamenable, weakly amenable and that belong to Ozawa's class S.

Self-consistent semi-analytic models of the first stars

description: We have developed a semi-analytic framework to model the large-scale evolution of the first Population III (Pop III) stars and the transition to metal-enriched star formation. Our model follows dark matter halos from cosmological N-body simulations, utilizing their individual merger histories and three-dimensional positions, and applies physically motivated prescriptions for star formation and feedback from Lyman-Werner (LW) radiation, hydrogen ionizing radiation, and external metal enrichment due to supernovae winds. This method is intended to complement analytic studies, which do not include clustering or individual merger histories, and hydrodynamical cosmological simulations, which include detailed physics, but are computationally expensive and have limited dynamic range. Utilizing this technique, we compute the cumulative Pop III and metal-enriched star formation rate density (SFRD) as a function of redshift at $z \geq 20$. We find that varying the model parameters leads to significant qualitative changes in the global star formation history. The Pop III star formation efficiency and the delay time between Pop III and subsequent metal-enriched star formation are found to have the largest impact. The effect of clustering (i.e. including the three-dimensional positions of individual halos) on various feedback mechanisms is also investigated. The impact of clustering on LW and ionization feedback is found to be relatively mild in our fiducial model, but can be larger if external metal enrichment can promote metal-enriched star formation over large distances.

Construction of a blow-up solution for the Complex Ginzburg-Landau equation in some critical case

description: We construct a solution for the Complex Ginzburg-Landau equation in some critical case, which blows up in finite time $T$ only at one blow-up point. We also give a sharp description of its profile. The proof relies on the reduction of the problem to a finite dimensional one, and the use of index theory to conclude. The interpretation of the parameters of the finite dimension problem in terms of the blow-up point and time allows to prove the stability of the constructed solution.
