description: We computed the leading order Wilson coefficients relevant to all the exclusive $b\to s\ell^+\ell^-$ decays in the framework of Two Higgs Doublet Model (2HDM) with a softly broken $\mathbb{Z}_2$ symmetry by including the $\mathcal{O}(m_b)$ corrections. We elucidate the issue of appropriate matching between the full and the effective theory when dealing with the (pseudo-)scalar operators for which keeping the external momenta different from zero is necessary. We then make a phenomenological analysis by using the measured $\mathcal{B}(B_s\to μ^+μ^-)$ and $\mathcal{B}(B\to K μ^+μ^-)_{\mathrm{high}-q^2}$, for which the hadronic uncertainties are well controlled, and discussed their impact on various types of 2HDM. A brief discussion of the decays with $τ$-leptons in the final state is also made.

description: Symmetric Space Sine-Gordon theories are two-dimensional massive integrable field theories, generalising the Sine-Gordon and Complex Sine-Gordon theories. To study their integrability properties on the real line, it is necessary to introduce a subtracted monodromy matrix. Moreover, since the theories are not ultralocal, a regularisation is required to compute the Poisson algebra for the subtracted monodromy. In this article, we regularise and compute this Poisson algebra for certain configurations, and show that it can both satisfy the Jacobi identity and imply the existence of an infinite number of conserved quantities in involution.

Data-adaptive Active Sampling for Efficient Graph-Cognizant Classification

Year: 2017
Subjects: subject: Machine Learning (stat.ML)
subject: FOS: Computer and information sciences

description: The present work deals with active sampling of graph nodes representing training data for binary classification. The graph may be given or constructed using similarity measures among nodal features. Leveraging the graph for classification builds on the premise that labels across neighboring nodes are correlated according to a categorical Markov random field (MRF). This model is further relaxed to a Gaussian (G)MRF with labels taking continuous values - an approximation that not only mitigates the combinatorial complexity of the categorical model, but also offers optimal unbiased soft predictors of the unlabeled nodes. The proposed sampling strategy is based on querying the node whose label disclosure is expected to inflict the largest change on the GMRF, and in this sense it is the most informative on average. Such a strategy subsumes several measures of expected model change, including uncertainty sampling, variance minimization, and sampling based on the $Σ-$optimality criterion. A simple yet effective heuristic is also introduced for increasing the exploration capabilities of the sampler, and reducing bias of the resultant classifier, by taking into account the confidence on the model label predictions. The novel sampling strategies are based on quantities that are readily available without the need for model retraining, rendering them computationally efficient and scalable to large graphs. Numerical tests using synthetic and real data demonstrate that the proposed methods achieve accuracy that is comparable or superior to the state-of-the-art even at reduced runtime.
title: The reform treatises and discourse of early Tudor Ireland, c. 1515-1541
Creators: name: Marshall, CT
Publisher: name: University of Tasmania
Year: 2019

description: The aim of this thesis is to offer a detailed examination and analysis of reform literature concerning the Lordship of Ireland between 1515 and 1541. It addresses questions relating to the dating, authorship, and content of reform discourse, and explores its implications in order to provide a nuanced assessment of the roles English and Anglo‐Irish officials, as well as the crown, played in influencing and advancing a practical reform agenda for Ireland. Many of the complaints of the authors of the reform discourse revolved around cultural tensions and attempts to dislodge ‘overmighty’ earls who had become de facto governors of the lordship. Their concerns also reflected broader fears about the power wielded by the other great magnates, as well as notable lords and churchmen of Ireland. The rise of Kildare power in particular presented enduring problems, bringing into relief the most significant impetus for reform described in the discourse. This thesis also recognises the significance of intellectual currents that came to bear on aspirations for reform. Accordingly, from the fifteenth century, it investigates the ideological roots of reform, focussing on the influence of humanism and concomitant ideas of the ‘commonweal’. How those intellectual currents influenced reform writers, how their opinions were further moulded by contemporary events and circumstances, and how these came to bear on the crown and manifested in official policy is also explored. The 1515 treatise, the ‘State of Ireland’, in particular, is examined in depth, providing as it does an important intellectual bridge across the traditional medieval and early modern boundary, defining a standard that would be both complemented and challenged in future treatises and correspondence. The cumulative influence of the discourse on the crown and how it affected Henry VIII’s disposition towards reform in the lordship – intellectually and practically – is also considered in light of his correspondence with those involved in the Dublin administration. Accordingly, this thesis attempts to reconcile Henry VIII’s evolving views of governance in Ireland with some historians’ contention of a humanist‐inspired ‘reforming milieu’ based in the Pale. It will consider whether some Palesmen shrewdly leveraged the language of humanism to ingratiate themselves with the king so that their concerns were more favourably received. The study of early Tudor reform discourse provides important insights into the militaristic and colonialist events of subsequent decades. Indeed, Henry’s moderate approach to governance in Ireland, which gradually took shape after 1515 and culminated in the parliamentary act that made him King of Ireland in 1541 and the conciliatory programme of surrender and regrant, died with him in 1547, having catastrophic repercussions for centuries to come.

Search for associated production of dark matter with a Higgs boson decaying to b b-bar or gamma-gamma at sqrt(s) = 13 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2017
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for dark matter is performed using events with large missing transverse momentum and a Higgs boson decaying either to a pair of bottom quarks or to a pair of photons. The data from proton-proton collisions at a center-of-mass energy of 13 TeV, collected in 2015 with the CMS detector at the LHC, correspond to an integrated luminosity of 2.3 inverse femtobarns. Results are interpreted in the context of a Z'-two-Higgs-doublet model, where the gauge symmetry of the standard model is extended to a U(1)[Z'] group, with a new massive Z' gauge boson, and the Higgs sector is extended with four additional Higgs bosons. In this model, a high-mass resonance Z' decays into a pseudoscalar boson A and a light SM-like Higgs boson, and the A decays to a pair of dark matter particles. No significant excesses are observed over the background prediction. Combining results from the two decay channels yields exclusion limits in the signal cross section in the m[Z']-m[A] phase space. For example, the observed data exclude the Z' mass range from 600 to 1860 GeV, for Z' coupling strength g[Z'] = 0.8, the coupling of A with dark matter particles g[chi] = 1, the ratio of the vacuum expectation values tan[beta] = 1, and m[A] = 300 GeV. The results of this analysis are valid for any dark matter particle mass below 100 GeV.

description: Spatiotemporal vortex pulses are wave packets that carry transverse orbital angular momentum, exhibiting exotic structured wavefronts that can twist through space and time. Existing methods to generate these pulses require complex setups like spatial light modulators or computer-optimized structures. Here, we demonstrate a new approach to generate spatiotemporal vortex pulses using just a simple diffractive grating. The key is constructing a phase vortex in frequency-momentum space by leveraging symmetry, resonance, and diffraction. Our approach is applicable to any wave system. We use a liquid surface wave platform to directly demonstrate and observe the real-time generation and evolution of spatiotemporal vortex pulses. This straightforward technique provides opportunities to explore pulse dynamics and potential applications across different disciplines.

title: The facilitation of self-directed learning in teachers through person-centred coaching
Creators: name: Schmitz, JA
Publisher: name: University of Tasmania
Year: 2019

description: Research on the efficacy of non-directive person-centred approaches as professional development in the education sector is scarce in comparison to other contexts, such as corporate settings. Even within corporate contexts where coaching has been studied and lauded, some conclusions have been derived purely from self-reported data that lack an empirical and theoretical foundation. This dissertation reports on a multiplecase study which explored the use of non-directive coaching to facilitate self-directed learning in teachers employed in an international through-train school. An interpretivist paradigm was used to interpret the situation, events, and perspectives of the teachers in the study. The study was deliberately bound by identifying the time and place, the specific coaching framework (GROW – Goal, Reality, Options, and Will) and approach (person-centred coaching), and context of the study to keep it achievable in terms of scope. A multiple-case study involving semi-structured interviews and online surveys provided rich descriptions of, and drew analytic generalisations from, the coaching interactions in the context of the non-directive coaching pathway in the primary school. The findings revealed that client-centered theory provides a theoretical foundation for non-directive coaching that encompasses the attitudes of authenticity, non-judgmental respect, and empathic accuracy. The expression of these person-centred attitudes by coaches, as experienced by the learners in this study, was connected with the formation of trustful relationships, learner agency, focused and meaningful goal setting, effective action, and useful feedback through non-directive reflection. The findings from this study suggest that non-directive coaching is an effective intervention for facilitating self-directed learning in teachers and provides further opportunities for research, such as exploring the use of coaching to facilitate self-directed learning in students. As this study used internally trained coaches that had pre-existing relationships with the learners, another possible inquiry is an investigation into the effect of established relationships on the formation of trustful coaching partnerships.

description: Dissipation is ubiquitous in nature and plays a crucial role in quantum systems such as causing decoherence of quantum states. Recently, much attention has been paid to an intriguing possibility of dissipation as an efficient tool for preparation and manipulation of quantum states. Here we report the realization of successful demonstration of a novel role of dissipation in a quantum phase transition using cold atoms. We realize an engineered dissipative Bose-Hubbard system by introducing a controllable strength of two-body inelastic collision via photo-association for ultracold bosons in a three-dimensional optical lattice. In the dynamics subjected to a slow ramp-down of the optical lattice, we find that strong on-site dissipation favors the Mott insulating state: the melting of the Mott insulator is delayed and the growth of the phase coherence is suppressed. The controllability of the dissipation is highlighted by quenching the dissipation, providing a novel method for investigating a quantum many-body state and its non-equilibrium dynamics.

description: TThe Toda-Brumer-Duff (TBD) is an analytical criterion for estimating the local exponential rate of divergence between nearby trajectories in dynamical systems, and it is employed as a test for assessing the existence of chaos therein. It is fairly simple, intuitive, and works well in several situations, hence gained quite a wide popularity, yet it is known to be not rigorous since predicts ``false positives'', i.e., flags as chaotic systems that are instead regular. We revisit here the TBD criterion in order to understand the causes of its failures, and pinpoint that the problem with it is due to two reasons: (a) the TBD criterion does not constrain the trajectories to lie on the same energy hypersurface; (b) it does not distinguish between the divergence of trajectories along or perpendicularly to the direction of the flow, the former being irrelevant for assessing the presence of chaos. We show how both points can be incorporated within the TBD framework, yielding an amended criterion which, when applied to some reference cases, interprets correctly the kind of dynamics observed.

title: Polymer-inorganic hybrid nanoparticles via polymerization-induced self-assembly
Creators: name: Teo, GH
Publisher: name: University of Tasmania
Year: 2019

description: Silica nanoparticles are commonly integrated within polymeric matrices to form composite materials, due to their non-toxic nature, chemical resistance and physical properties. Polymer-silica colloidal nanocomposites are the most studied class of hybrid nanoparticles and their applications can be tailored based on synthetic approaches. The aims of this work were to prepare polymer-silica colloidal nanocomposites via a combination of reversible deactivation radical polymerization, self-assembly and sol-gel chemistry. This approach enabled the preparation of hybrid nanoparticles with controllable shape and size. The influences of compositional design (e.g. block copolymer architecture), solvent and initiating systems were also studied. Firstly, polymer nanoparticles were prepared by Polymerization-Induced Self-Assembly (PISA) in ethanol where the solvophilic block was an alkoxysilane-functional methacrylate. Spherical nanoparticles and polymeric vesicles were successfully prepared. A solid silica shell was successfully grown from the particle surface via subsequent hydrolysis and condensation of tetraethyl orthosilicate. Secondly, block copolymer self-assembly was studied where the alkoxysilane functionality was present in the core-forming block. This approach was not viable by aqueous PISA emulsion polymerization. A solvent-mediated self-assembly approach was thus adopted, yielding spherical nanoparticles in water, and a mixture of spheres and vesicles in n-hexane. Finally, the reactivity of alkoxysilane-functional methacrylates was exploited to prepare triblock copolymers as surfactants where the interfacial block could be crosslinked via hydrolysis and condensation. Triblock copolymers were either formed separately (and used to stabilize oil-in-water miniemulsions) or in-situ via the PISA method. The encapsulation of Nile Red in the particle core was achieved in parallel with self-assembly and the retention rate was improved through interfacial crosslinking.

description: Sensemaking in unfamiliar domains can be challenging, demanding considerable user effort to compare different options with respect to various criteria. Prior research and our formative study found that people would benefit from reading an overview of an information space upfront, including the criteria others previously found useful. However, existing sensemaking tools struggle with the "cold-start" problem -- it not only requires significant input from previous users to generate and share these overviews, but such overviews may also turn out to be biased and incomplete. In this work, we introduce a novel system, Selenite, which leverages Large Language Models (LLMs) as reasoning machines and knowledge retrievers to automatically produce a comprehensive overview of options and criteria to jumpstart users' sensemaking processes. Subsequently, Selenite also adapts as people use it, helping users find, read, and navigate unfamiliar information in a systematic yet personalized manner. Through three studies, we found that Selenite produced accurate and high-quality overviews reliably, significantly accelerated users' information processing, and effectively improved their overall comprehension and sensemaking experience.

description: A previous work found that a nonminimally coupled theory of gravity can, under appropriate conditions, give rise to an additional contribution to the field equations interpreted as dark matter [1]: in particular, the density of this dark matter component was found to scale as a power of the density of visible matter. However, no explicit solution for the modified field equations was provided, so that a direct computation of the specific density profile followed by visible matter is missing. This question is now addressed: analytical solutions to the modified field equations are derived in the appropriate perturbative regime and characterised, with an emphasis on directly obtaining the visible matter profile in a self-consistent way. We compare with known profiles for visible and dark matter and obtain constraints on the parameters of the model.

description: From the formation mechanisms of stars and compact objects to nuclear physics, modern astronomy frequently leverages surveys to understand populations of objects to answer fundamental questions. The population of dark and isolated compact objects in the Galaxy contains critical information related to many of these topics, but is only practically accessible via gravitational microlensing. However, photometric microlensing observables are degenerate for different types of lenses, and one can seldom classify an event as involving either a compact object or stellar lens on its own. To address this difficulty, we apply a Bayesian framework that treats lens type probabilistically and jointly with a lens population model. This method allows lens population characteristics to be inferred despite intrinsic uncertainty in the lens-class of any single event. We investigate this method's effectiveness on a simulated ground-based photometric survey in the context of characterizing a hypothetical population of primordial black holes (PBHs) with an average mass of $30 M_{\odot}$. On simulated data, our method outperforms current black hole (BH) lens identification pipelines and characterizes different subpopulations of lenses while jointly constraining the PBH contribution to dark matter to ${\approx}25$\%. Key to robust inference, our method can marginalize over population model uncertainty. We find the lower mass cutoff for stellar origin BHs, a key observable in understanding the BH mass gap, particularly difficult to infer in our simulations. This work lays the foundation for cutting-edge PBH abundance constraints to be extracted from current photometric microlensing surveys.

description: A Bloom filter is a simple data structure supporting membership queries on a set. The standard Bloom filter does not support the delete operation, therefore, many applications use a counting Bloom filter to enable deletion. This paper proposes a generalization of the counting Bloom filter approach, called "autoscaling Bloom filters", which allows adjustment of its capacity with probabilistic bounds on false positives and true positives. In essence, the autoscaling Bloom filter is a binarized counting Bloom filter with an adjustable binarization threshold. We present the mathematical analysis of the performance as well as give a procedure for minimization of the false positive rate.

title: Ethical considerations for deep brain stimulation and other invasive neurotechnological trials in people with Alzheimer's disease
Creators: name: Viaña, JNM
Publisher: name: University of Tasmania
Year: 2019

description: Alzheimer’s disease is the leading cause of dementia worldwide, affecting more than 30 million people. FDA-approved drugs only provide temporary relief to memory problems, and no disease-modifying therapies are currently available. As such, different therapeutic modalities are being investigated to address the biological and/or cognitive manifestations of the disease. A number of these therapies are highly invasive and require stereotactic surgery, potentially posing a greater risk of harms to a vulnerable population with cognitive deficits that limit their ability to provide fully informed consent. Using an interdisciplinary and pragmatic approach to bioethical inquiry, this dissertation examines studies on deep brain stimulation in people with Alzheimer’s disease, reviewing clinical trials and relevant animal studies to highlight pressing ethical concerns that ongoing and forthcoming trials need to address. By having three major publications during the course of the PhD as the main chapters, This thesis aims to enumerate ethical issues that encompass the genetic, neurobiological, cognitive, individual, and societal dimensions of deep brain stimulation for Alzheimer’s disease. These ethical considerations can then be extended into other forms of novel neurosurgical trials such as cell implantation and gene therapy. Finally, this thesis incorporates other publications during the PhD to illustrate further conundrums on the use of deep brain stimulation and highlight directions for future bioethics research on the use of invasive neurotechnologies for dementia in terms of the importance of genetic underpinnings, clinical translation issues, communication of research objectives, media portrayal, and implications on criminal responsibility.
title: Transient suppression in hybrid electric ship power systems
Creators: name: Shagar, V
Publisher: name: University of Tasmania
Year: 2019

description: The requirements for power quality in ship power systems have been increasing over the years. This is an essential consequence of improving the efficiency of the onboard power network and reduce emissions in the long term. The connection of sophisticated navigation and measuring instruments into the grid has also necessitated a higher quality of power to ensure optimal operating conditions for all the loads and avoid malfunction of equipment onboard a ship. The most significant challenge to maintain power quality for the shipboard power system is to mitigate the transient conditions that arise due to the widely varying load conditions imposed by varying sea conditions as well as fluctuating onboard power demands. This work has attempted to illustrate the extent of the transient phenomena due to load changes in the case of vessels with hybrid mechanical and electrical propulsion. Subsequently, control solutions to limit and reduce such transient conditions and their propagation that include energy storage devices such as the capacitor and battery have been developed. A shipboard power system with hybrid propulsion has been modeled and the transient responses to various types of load changes during the course of different modes of operation possible for the hybrid system have been analyzed. An active damping strategy has been developed to reduce the torsional vibrations at the drive shaft of the thruster due to extreme load conditions while avoiding overdesign of the shaft itself. The strategy has been extended further to incorporate a capacitor clamped inverter to reduce the electrical transients that are caused by propagation of these transients from the mechanical portion of the hybrid propulsion system into the electrical system. A Model Predictive Control (MPC) strategy has also been developed for a Battery Energy Storage System (BESS) to mitigate the electrical transients arising as a result of propulsion and service load transients while keeping the main engine in the optimum operating range. The MPC power converter control allows for the battery to smoothen the electrical frequency profile during different types of extreme load change conditions and allows for charging and discharging the battery repeatedly. The findings of this research work have significant implications in defining the extent of transient conditions in hybrid power systems. In addition, the efficacy of integrating an energy storage system into the hybrid electric propulsion power network in order to reduce the transients has also been proven.

description: A photonic circuit is generally described as a structure in which light propagates by unitary exchange and transfers reversibly between channels. In contrast, the term `diffusive' is more akin to a chaotic propagation in scattering media, where light is driven out of coherence towards a thermal mixture. Based on the dynamics of open quantum systems, the combination of these two opposites can result in novel techniques for coherent light control. The crucial feature of these photonic structures is dissipative coupling between modes, via an interaction with a common reservoir. Here, we demonstrate experimentally that such systems can perform optical equalisation to smooth multimode light, or act as a distributor, guiding it into selected channels. Quantum thermodynamically, these systems can act as catalytic coherent reservoirs by performing perfect non-Landauer erasure. For lattice structures, localised stationary states can be supported in the continuum, similar to compacton-like states in conventional flat band lattices.

description: Luminous high-redshift quasars can be used to probe of the intergalactic medium (IGM) in the early universe because their UV light is absorbed by the neutral hydrogen along the line of sight. They help us to measure the neutral hydrogen fraction of the high-z universe, shedding light on the end of reionization epoch. In this paper, we present a discovery of a new quasar (PSO J006.1240+39.2219) at redshift $z=6.61\pm0.02$ from Panoramic Survey Telescope & Rapid Response System 1. Including this quasar, there are nine quasars above $z>6.5$ up to date. The estimated continuum brightness is $M_\text{1450}$=$-25.96\pm0.08$. PSO J006.1240+39.2219 has a strong Ly~$α$ emission compared with typical low-redshift quasars, but the measured near-zone region size is $R_\text{NZ}=3.2\pm1.1$ proper megaparsecs, which is consistent with other quasars at z$\sim$6.

description: We present a novel approach to hybrid RANS/LES wall modeling based on function enrichment, which overcomes the common problem of the RANS-LES transition and enables coarse meshes near the boundary. While the concept of function enrichment as an efficient discretization technique for turbulent boundary layers has been proposed in an earlier article by Krank & Wall (J. Comput. Phys. 316 (2016) 94-116), the contribution of this work is a rigorous derivation of a new multiscale turbulence modeling approach and a corresponding discontinuous Galerkin discretization scheme. In the near-wall area, the Navier-Stokes equations are explicitly solved for an LES and a RANS component in one single equation. This is done by providing the Galerkin method with an independent set of shape functions for each of these two methods; the standard high-order polynomial basis resolves turbulent eddies where the mesh is sufficiently fine and the enrichment automatically computes the ensemble-averaged flow if the LES mesh is too coarse. As a result of the derivation, the RANS model is consistently applied solely to the RANS degrees of freedom, which effectively prevents the typical issue of a log-layer mismatch in attached boundary layers. As the full Navier-Stokes equations are solved in the boundary layer, spatial refinement gradually yields wall-resolved LES with exact boundary conditions. Numerical tests show the outstanding characteristics of the wall model regarding grid independence, superiority compared to equilibrium wall models in separated flows, and achieve a speed-up by two orders of magnitude compared to wall-resolved LES.

description: We investigate the connection between the classical Larmor formula and the quantum Unruh effect by computing the emitted power by a uniformly accelerated charged particle and its angular distribution in the coaccelerated frame. We consider a classical particle accelerated with nonzero charge only for a finite period and then take the infinite-time limit after removing the effects due to the initial charging and final discharging processes. We show that the result found for the interaction rates agrees with previous studies in which the period of acceleration with nonzero charge was taken to be infinite from the beginning. We also show that the power and angular distribution of emission, which is attributed either to the emission or absorption of a Rindler photon in the coaccelerated frame, is given by the Larmor formula, confirming that, at tree level, it is necessary to take into account the Unruh effect in order to reproduce the classical Larmor radiation formula in the coaccelerated frame.

description: Optical refrigeration of solids holds tremendous promise for applications in thermal management. It can be achieved through multiple mechanisms including inelastic anti-Stokes Brillouin and Raman scattering. However, engineering of these mechanisms remains relatively unexplored. The major challenge lies in the natural unfavorable imbalance in transition rates for Stokes and anti-Stokes scattering. We consider the influence of anisotropic photonic density of states on Raman scattering and derive expressions for cooling in such systems. We demonstrate optimization of the Raman cooling figure of merit considering all possible orientations for the material crystal and two example photonic crystals. We find that the anisotropic description of the photonic DoS and the optimization process is necessary to obtain the best Raman cooling efficiency for systems having lower symmetry. This general result applies to a wide array of other laser cooling methods in the presence of anisotropy.
