description: Edge-device collaboration has the potential to facilitate compute-intensive device pose tracking for resource-constrained mobile augmented reality (MAR) devices. In this paper, we devise a 3D map management scheme for edge-assisted MAR, wherein an edge server constructs and updates a 3D map of the physical environment by using the camera frames uploaded from an MAR device, to support local device pose tracking. Our objective is to minimize the uncertainty of device pose tracking by periodically selecting a proper set of uploaded camera frames and updating the 3D map. To cope with the dynamics of the uplink data rate and the user's pose, we formulate a Bayes-adaptive Markov decision process problem and propose a digital twin (DT)-based approach to solve the problem. First, a DT is designed as a data model to capture the time-varying uplink data rate, thereby supporting 3D map management. Second, utilizing extensive generated data provided by the DT, a model-based reinforcement learning algorithm is developed to manage the 3D map while adapting to these dynamics. Numerical results demonstrate that the designed DT outperforms Markov models in accurately capturing the time-varying uplink data rate, and our devised DT-based 3D map management scheme surpasses benchmark schemes in reducing device pose tracking uncertainty.

description: The Simons Observatory (SO) is a cosmic microwave background instrumentation suite being deployed in the Atacama Desert in northern Chile. The telescopes within SO use three types of dichroic transition-edge sensor (TES) detector arrays, with the 90 and 150 GHz Mid-Frequency (MF) arrays containing 65% of the approximately 68,000 detectors in the first phase of SO. All of the 26 required MF detector arrays have now been fabricated, packaged into detector modules, and tested in laboratory cryostats. Across all modules, we find an average operable detector yield of 84% and median saturation powers of (2.8, 8.0) pW with interquartile ranges of (1, 2) pW at (90, 150) GHz, respectively, falling within their targeted ranges. We measure TES normal resistances and superconducting transition temperatures on each detector wafer to be uniform within 3%, with overall central values of 7.5 mohm and 165 mK, respectively. Results on time constants, optical efficiency, and noise performance are also presented and are consistent with achieving instrument sensitivity forecasts.

description: Empathy, as defined in behavioral sciences, expresses the ability of human beings to recognize, understand and react to emotions, attitudes and beliefs of others. The lack of an operational definition of empathy makes it difficult to measure it. In this paper, we address two related problems in automatic affective behavior analysis: the design of the annotation protocol and the automatic recognition of empathy from spoken conversations. We propose and evaluate an annotation scheme for empathy inspired by the modal model of emotions. The annotation scheme was evaluated on a corpus of real-life, dyadic spoken conversations. In the context of behavioral analysis, we designed an automatic segmentation and classification system for empathy. Given the different speech and language levels of representation where empathy may be communicated, we investigated features derived from the lexical and acoustic spaces. The feature development process was designed to support both the fusion and automatic selection of relevant features from high dimensional space. The automatic classification system was evaluated on call center conversations where it showed significantly better performance than the baseline.

We develop several machine learning methods for the reconstruction of energy spectra of separate primary nuclei at energies 1-100 PeV, using the public data and Monte-Carlo simulations of the KASCADE experiment from the KCDC platform. We estimate the uncertainties of our methods, including the unfolding procedure, and show that the overall accuracy exceeds that of the method used in the original studies of the KASCADE experiment.

description: The Pan-STARRS1 Science Consortium have carried out a set of imaging surveys using the 1.4 giga-pixel GPC1 camera on the PS1 telescope. As this camera is composed of many individual electronic readouts, and covers a very large field of view, great care was taken to ensure that the many instrumental effects were corrected to produce the most uniform detector response possible. We present the image detrending steps used as part of the processing of the data contained within the public release of the Pan-STARRS1 Data Release 1 (DR1). In addition to the single image processing, the methods used to transform the 375,573 individual exposures into a common sky-oriented grid are discussed, as well as those used to produce both the image stack and difference combination products.

description: We study the classification performance of Kronecker-structured models in two asymptotic regimes and developed an algorithm for separable, fast and compact K-S dictionary learning for better classification and representation of multidimensional signals by exploiting the structure in the signal. First, we study the classification performance in terms of diversity order and pairwise geometry of the subspaces. We derive an exact expression for the diversity order as a function of the signal and subspace dimensions of a K-S model. Next, we study the classification capacity, the maximum rate at which the number of classes can grow as the signal dimension goes to infinity. Then we describe a fast algorithm for Kronecker-Structured Learning of Discriminative Dictionaries (K-SLD2). Finally, we evaluate the empirical classification performance of K-S models for the synthetic data, showing that they agree with the diversity order analysis. We also evaluate the performance of K-SLD2 on synthetic and real-world datasets showing that the K-SLD2 balances compact signal representation and good classification performance.

We provide with a closed solution as to the variation-derivative motion equations in the general case of a normal form (symbol) chosen. We show that the action in the path integral does depend actually on a particular choice of a normal symbol. We have determined both the aspects of the latter dependence: the specific boundary conditions for virtual trajectories, and the specific boundary terms in the action.

description: We develop a multi-patch and multi-group model that captures the dynamics of an infectious disease when the host is structured into an arbitrary number of groups and interacts into an arbitrary number of patches where the infection takes place. In this framework, we model host mobility that depends on its epidemiological status, by a Lagrangian approach. This framework is applied to a general SEIRS model and the basic reproduction number $\mathcal{R_0}$ is derived. The effects of heterogeneity in groups, patches and mobility patterns on $\mathcal{R_0}$ and disease prevalence are explored. Our results show that for a fixed number of groups, the basic reproduction number increases with respect to the number of patches and the host mobility patterns. Moreover, when the mobility matrix of susceptible individuals is of rank one, the basic reproduction number is explicitly determined and was found to be independent of the latter. The cases where mobility matrices are of rank one capture important modeling scenarios. Additionally, we study the global analysis of equilibria for some special cases. Numerical simulations are carried out to showcase the ramifications of mobility pattern matrices on disease prevalence and basic reproduction number.

description: We propose a novel inverse rendering method that enables the transformation of existing indoor panoramas with new indoor furniture layouts under natural illumination. To achieve this, we captured indoor HDR panoramas along with real-time outdoor hemispherical HDR photographs. Indoor and outdoor HDR images were linearly calibrated with measured absolute luminance values for accurate scene relighting. Our method consists of three key components: (1) panoramic furniture detection and removal, (2) automatic floor layout design, and (3) global rendering with scene geometry, new furniture objects, and a real-time outdoor photograph. We demonstrate the effectiveness of our workflow in rendering indoor scenes under different outdoor illumination conditions. Additionally, we contribute a new calibrated HDR (Cali-HDR) dataset that consists of 137 calibrated indoor panoramas and their associated outdoor photographs.

description: A novel method combining the ensemble refinement by maximum entropy principle and the force field fitting approach is presented. Its formulation allows to continuously interpolate in between these two methods, which can thus be interpreted as two limiting cases. A cross-validation procedure enables to correctly assess the relative weight of both of them, distinguishing scenarios where the combined approach is meaningful from those in which either ensemble refinement or force field fitting separately prevails. The efficacy of their combination is examined for a realistic case study of RNA oligomers. Within the new scheme, molecular dynamics simulations are integrated with experimental data provided by nuclear-magnetic-resonance measures. We show that force field corrections are in general superior when applied to the appropriate force field terms, but are automatically discarded by the method when applied to inappropriate force field terms.

description: Analytic consideration of the Bohr-Oppenheimer (BO) approximation for diatomic molecules is proposed: accurate analytic interpolation for potential curve consistent with its rovibrational spectra is found. It is shown that in the Bohr-Oppenheimer approximation for four lowest electronic states $1sσ_g$ and $2pσ_u$, $2p π_u$ and $3d π_g$ of H$_2^+$, the ground state X$^2Σ^+$ of HeH and the two lowest states $^1Σ^+_g$ and $^3Σ^+_u$ of H$_2$, the potential curves can be analytically interpolated in full range of internuclear distances $R$ with not less than {4-5-6} figures. Approximation based on matching the Taylor-type expansion at small $R$ and a combination of the multipole expansion with one-instanton type contribution at large distances $R$ is given by two-point Padé approximant. The position of minimum, when exists, is predicted within 1$\%$ or better. For the molecular ion H$_2^+$ in the Lagrange mesh method, the spectra of vibrational, rotational and rovibrational states $(ν,L)$ associated with $1sσ_g$ and $2pσ_u$, $2p π_u$ and $3d π_g$ potential curves is calculated. In general, $1sσ_g$ electronic curve contains 420 rovibrational states, which increases up to 423 when we are beyond BO approximation. For the state $2pσ_u$ the total number of rovibrational states (all with $ν=0$) is equal to 3, within or beyond Bohr-Oppenheimer approximation. As for the state $2pπ_u$ within the Bohr-Oppenheimer approximation the total number of the rovibrational bound states is equal to 284. The state $3dπ_g$ is repulsive, no rovibrational state is found. The ground state potential curve of the heteronuclear molecule HeH does not support rovibrational states. Accurate analytical expression for the potential curves of the hydrogen molecule H$_2$ for the states $^1Σ^+_g$ and $^3Σ^+_u$ is presented.

title: State-corporate crime and ecocide : a critical study of the Carmichael Coal Mine
Creators: name: Hasler, O
Publisher: name: University of Tasmania
Year: 2019

description: This thesis provides a substantive case study of the Carmichael Coal Mine and Rail Project (‘Carmichael Project’). The study is an exegesis of Adani’s proposed mega coal mine in Queensland, including the intricacies of political decision-making, and how this case informs, critiques and develops global discourses in ecocide. It adopts an expedition in archaeological and contemporary knowledge and explores the background, politics and reasoning of the Australian governments’ multiple decisions to approve and support what will be the world’s largest-ever coal mine. It examines processes of political decision-making during a period of global economic coal down-turn, amidst an unprecedented period of coal industry bankruptcy and redundancy, and at a time when continued coal production is predicted to cause devastating green-house gas emissions and climate change. This thesis, as discussed later in Chapter Two, draws on a unique and originally constructed archive comprising diverse and multiple sources not previously compiled. This extensive dataset is an authoritative library and forms the basis underpinning the analyses of this thesis. As an exercise in green criminology, this thesis recognises that environmental degradation is often the result of crimes of the powerful; that is, it arises through their actions and inactions, justifications and denials of state and corporate actors. The thesis not only presents the story of who the stakeholders are and why they want to see the Carmichael Project approved, but it also argues for the need to establish an international law against ecocide – the term that arguably encompasses the environmental destruction which would result from the Project – to prevent the possibility of approval for similar projects in the future.
Multivariate Submodular Optimization

Year: 2016
Subjects: subject: Data Structures and Algorithms (cs.DS)

description: Submodular functions have found a wealth of new applications in data science and machine learning models in recent years. This has been coupled with many algorithmic advances in the area of submodular optimization: (SO) $\min/\max~f(S): S \in \mathcal{F}$, where $\mathcal{F}$ is a given family of feasible sets over a ground set $V$ and $f:2^V \rightarrow \mathbb{R}$ is submodular. In this work we focus on a more general class of \emph{multivariate submodular optimization} (MVSO) problems: $\min/\max~f (S_1,S_2,\ldots,S_k): S_1 \uplus S_2 \uplus \cdots \uplus S_k \in \mathcal{F}$. Here we use $\uplus$ to denote disjoint union and hence this model is attractive where resources are being allocated across $k$ agents, who share a `joint' multivariate nonnegative objective $f(S_1,S_2,\ldots,S_k)$ that captures some type of submodularity (i.e. diminishing returns) property. We provide some explicit examples and potential applications for this new framework. For maximization, we show that practical algorithms such as accelerated greedy variants and distributed algorithms achieve good approximation guarantees for very general families (such as matroids and $p$-systems). For arbitrary families, we show that monotone (resp. nonmonotone) MVSO admits an $α(1-1/e)$ (resp. $α\cdot 0.385$) approximation whenever monotone (resp. nonmonotone) SO admits an $α$-approximation over the multilinear formulation. This substantially expands the family of tractable models for submodular maximization. For minimization, we show that if SO admits a $β$-approximation over \emph{modular} functions, then MVSO admits a $\frac{β\cdot n}{1+(n-1)(1-c)}$-approximation where $c\in [0,1]$ denotes the curvature of $f$, and this is essentially tight. Finally, we prove that MVSO has an $αk$-approximation whenever SO admits an $α$-approximation over the convex formulation.

title: Optogenetic manipulation of calcineurin signalling
Creators: name: Devinish, EJ
Publisher: name: University of Tasmania
Year: 2019

description: Calcineurin (CaN) is a calcium (Ca\(^{2+}\)) dependent protein phosphatase that is crucial for mammalian development. The requirement for CaN signalling has been indicated by genetic and pharmacological experiments, and further insights into the spatial and temporal characteristics of CaN activity would be valuable in understanding its specific function in development. During development of the nervous system, axon outgrowth and pathfinding towards synaptic partners is guided by environmental cues detected by the growth cone, a navigational structure at the axon tip. Many guidance cues trigger Ca2+ influx that is asymmetric across the growth cone, and the guidance events that follow require CaN and Ca2+/calmodulin dependent protein kinase II (CaMKII). It has been hypothesised that CaN signalling occurs in spatially restricted regions of the growth cone, following the patterns of Ca2+ influx. Optogenetic techniques are uniquely positioned to probe the spatial and temporal patterns of protein signalling, because they use light to control protein activity. Modern optics can precisely control the illumination pattern in spatial and temporal dimensions. The aim of this project was to develop optogenetic tools to manipulate CaN signalling. This thesis will present approaches that can robustly inhibit CaN signalling in living cells using blue (<500 nm) or red (~650 nm) light. These approaches utilise reactive oxygen species, generated when certain chromophores are excited, to disrupt the phosphatase function of CaN. For the blue light version of the tool, the photosensitising fluorescent protein miniSOG is used, while the red light version utilises a novel photosensitising florescent dye (dibromo-JF649) that binds to the HaloTag protein domain. To target reactive oxygen species to endogenous CaN, the miniSOG or HaloTag domain is tethered to calcineurin B, an accessory subunit that incorporates into endogenous CaN complexes. Using both a live cell assay involving nuclear factor of activated T-cells (NFAT) in HEK293A cells, and biochemical measurement of CaN activity in cellular protein extracts, the data presented will show that CaN is selectively inhibited by these tools, and the extent of inhibition is dependent on the duration and intensity of the light. To activate CaN signalling using optogenetics, the protein must be modified to replace its regulatory mechanism with a light inducible module. Several approaches have been designed in this project, and the proteins that comprise each design have undergone initial screening. Data will be presented that demonstrate the potential of each approach, and where further development is required to achieve control of CaN signalling.

description: We investigate the impact of galactic outflow modelling on the formation and evolution of a disc galaxy, by performing a suite of cosmological simulations with zoomed-in initial conditions of a Milky Way-sized halo. We verify how sensitive the general properties of the simulated galaxy are to the way in which stellar feedback triggered outflows are implemented, keeping initial conditions, simulation code and star formation (SF) model all fixed. We present simulations that are based on a version of the GADGET3 code where our sub-resolution model is coupled with an advanced implementation of Smoothed Particle Hydrodynamics that ensures a more accurate fluid sampling and an improved description of gas mixing and hydrodynamical instabilities. We quantify the strong interplay between the adopted hydrodynamic scheme and the sub-resolution model describing SF and feedback. We consider four different galactic outflow models, including the one introduced by Dalla Vecchia and Schaye (2012) and a scheme that is inspired by the Springel and Hernquist (2003) model. We find that the sub-resolution prescriptions adopted to generate galactic outflows are the main shaping factor of the stellar disc component at low redshift. The key requirement that a feedback model must have to be successful in producing a disc-dominated galaxy is the ability to regulate the high-redshift SF (responsible for the formation of the bulge component), the cosmological infall of gas from the large-scale environment, and gas fall-back within the galactic radius at low redshift, in order to avoid a too high SF rate at $z=0$.

title: An applied investigation of Ian Pearce’s mature output : interpretation and reinterpretation of traditional jazz within a Tasmanian context
Creators: name: Boden, MJ
Publisher: name: University of Tasmania

description: Ian Pearce (1921 - 2012) was an iconic figure within the Australian jazz scene, and pioneer of traditional jazz performance practice in Tasmania. His development and approach to the assimilation of traditional jazz practices provide a model for solving the problems arising from artistic isolation, and underpin the development of his unique creative voice. This research project takes Ian Pearce’s contribution as a case study, analysing his development and improvisational modalities, in order to uncover a method of interpretation and reinterpretation of traditional jazz within the context of Tasmanian jazz heritage, that in turn has enhanced my own performance practice. This project documents processes of experiential learning through performance based on a folio of original work including commercial releases The Last Sheiks (2013) and Post Matinée (2016), and two live concert recordings. The accompanying exegesis contextualizes this research conducted through performance, adopting an auto-ethnographic approach for critical reflection on the work in the folio. It also includes a body of transcriptions of Pearce’s work that provides a unique contribution to the understanding of the musical language of a key figure within Australian jazz; an area of academic study that has thus far been under-represented.

description: Though the Standard Model (SM) provides a very elegant description of the interactions among fundamental particles, there are ample evidences suggesting that new physics is needed. In particular, extending the scalar sector has enough motivation from vacuum stability, electroweak phase transition and various other sectors. Among different such extensions, the two-Higgs-doublet model (THDM) is the simplest one that preserves the electroweak $ρ$ parameter. Flavour-changing neutral currents (FCNC) are usually avoided by implementing additional discrete symmetries, but this type of models are subject to severe phenomenological constraints. In the more general framework of the aligned THDM (ATHDM) tree-level FCNCs are avoided by choosing the same flavour structure for the Yukawa couplings of the two scalar doublets, which results in weaker phenomenological constraints. Here, we present a global fit of the ATHDM, using the package HEPfit that performs a bayesian analysis on the parameter-space of this model with the help of stability and perturbativity bounds, experimental data for various flavour and electroweak precision observables, and constraints from Higgs searches at the LHC. This global fit has been performed assuming that all additional scalars are heavier than the SM Higgs and that there are no extra sources of CP violation beyond the CKM phase.

description: Composition and parameterization of multicomponent predictive systems (MCPSs) consisting of chains of data transformation steps are a challenging task. Auto-WEKA is a tool to automate the combined algorithm selection and hyperparameter (CASH) optimization problem. In this paper, we extend the CASH problem and Auto-WEKA to support the MCPS, including preprocessing steps for both classification and regression tasks. We define the optimization problem in which the search space consists of suitably parameterized Petri nets forming the sought MCPS solutions. In the experimental analysis, we focus on examining the impact of considerably extending the search space (from approximately 22,000 to 812 billion possible combinations of methods and categorical hyperparameters). In a range of extensive experiments, three different optimization strategies are used to automatically compose MCPSs for 21 publicly available data sets. The diversity of the composed MCPSs found is an indication that fully and automatically exploiting different combinations of data cleaning and preprocessing techniques is possible and highly beneficial for different predictive models. We also present the results on seven data sets from real chemical production processes. Our findings can have a major impact on the development of high-quality predictive models as well as their maintenance and scalability aspects needed in modern applications and deployment scenarios.

description: Gradient compression alleviates expensive communication in distributed deep learning by sending fewer values and its corresponding indices, typically via Allgather (AG). Training with high compression ratio (CR) achieves high accuracy like DenseSGD, but has lower parallel scaling due to high communication cost (i.e., parallel efficiency). Using lower CRs improves parallel efficiency by lowering synchronization cost, but degrades model accuracy as well (statistical efficiency). Further, speedup attained with different models and CRs also varies with network latency, effective bandwidth and collective op used for aggregation. In many cases, collectives like Allreduce (AR) have lower cost than AG to exchange the same amount of data. In this paper, we propose an AR-compatible Topk compressor that is bandwidth-optimal and thus performs better than AG in certain network configurations. We develop a flexible communication strategy that switches between AG and AR based on which collective is optimal in the current settings, and model the pareto-relationship between parallel and statistical efficiency as a multi-objective optimization (MOO) problem to dynamically adjust CR and accelerate training while still converging to high accuracy.

Extending structures for associative conformal algebras

description: In this paper, we give a study of the $\mathbb{C}[\partial]$-split extending structures problem for associative conformal algebras. Using the unified product as a tool, which includes interesting products such as bicrossed product, cocycle semi-direct product and so on, a cohomological type object is constructed to characterize the $\mathbb{C}[\partial]$-split extending structures for associative conformal algebras. Moreover, using this theory, the extending structures of an associative conformal algebra $A$ which is free as a $\mathbb{C}[\partial]$-module by the $\mathbb{C}[\partial]$-module $Q=\mathbb{C}[\partial]x$ are described using flag datums of $A$. Furthermore, we give a classification of the extending structures of $A$ by $Q=\mathbb{C}[\partial]x$ in detail up to equivalence when $A$ is a free associative conformal algebra of rank 1.

description: We evaluate the entanglement entropy and entropic function of massive two dimensional QED (Schwinger model) at finite temperature, density, and $θ$-angle. In the strong coupling regime, the entropic function is dominated by the boson mass for large spatial intervals, and reduces to the CFT result for small spatial intervals. We also discuss the entanglement spectrum at finite temperature and a finite $θ$-angle.
