description: Inverse problems involve making inference about unknown parameters of a physical process using observational data. This article investigates an important class of inverse problems—the estimation of the initial condition of a spatio-temporal advection-diffusion process using spatially sparse data streams. Three spatial sampling schemes are considered, including irregular, nonuniform and shifted uniform sampling. The irregular sampling scheme is the general scenario, while computationally efficient solutions are available in the spectral domain for nonuniform and shifted uniform sampling. For each sampling scheme, the inverse problem is formulated as a regularized convex optimization problem that minimizes the distance between forward model outputs and observations. The optimization problem is solved by the Alternating Direction Method of Multipliers algorithm, which also handles the situation when a linear inequality constraint (e.g., non-negativity) is imposed on the model output. Numerical examples are presented, code is made available on GitHub, and discussions are provided to generate some useful insights of the proposed inverse modeling approaches.

RFID in perishable foods transportation : an analysis of the adoption of time-temperature monitoring technology for the transport of perishable foods
Creators: name: Thamworrawong, K
Publisher: name: University Of Tasmania
Year: 2023

description: This research provides an analysis of the adoption of time-temperature monitoring technologies (particularly RFID) for the transport of perishable foods. These technologies have been used to provide information during the transport of other commodities but there are very few studies on their adoption and use in the perishable food industry. Increasingly the perishable food industry is under pressure to provide higher quality, higher nutritional fresh foods and to address stricter standards covering food safety. There has also been real market pressure for organisations to minimise supply chain management costs, and maximise customer service and market opportunities. Therefore, the objective of this research was to examine the potential application of time-temperature monitoring in cold (refrigerated) supply chain management in Australia. This thesis presents five industry case studies that seek to understand the nature of the adoption of technology for environmental monitoring of the transport of perishable foods. These case studies explore the use of time-temperature monitoring equipment for the quality assurance of perishable food, supply chain relationship maintenance, fault diagnosis, and reduction of costs associated with reverse logistics. This research adopts a post-positivist epistemology and employs qualitative analysis of multiple case studies, using semi-structured interviews and a critical analysis approach to the derivation of effect-outcome models associated with the adoption of this technology. These approaches provide considerable insight into the logistics management of the transport of perishable foods across a range of industries, including seafood export, confectionary distribution and research into food safety. This exploratory research has identified a number of dependent variables, including Return on Investment, that characterise the outcomes of decisions relating to the adoption of time-temperature monitoring technologies. The study provides a preliminary model as the basis for further investigation into the use of time-temperature monitoring technology for surveillance of perishable foods. These findings are also relevant to industry in providing insight into the key issues that need to be considered when integrating environmental monitoring into supply chain management practices.

description: Stress-strain constitutive relations in solids with an internal angular degree of freedom can be modelled using Cosserat (also called micropolar) elasticity. In this paper, we explore the phenomenology for a natural extension of Cosserat materials that includes chiral active components and odd elasticity. We calculate static elastic properties of such a solid, where we show that static response to rotational stresses leads to strains that depend on both Cosserat and odd elasticity. We then compute the dispersion of linear solutions in these odd Cosserat materials in the overdamped regime and find the presence of \emph{exceptional points} in the dispersion relation. We discover that these exceptional points create a sharp boundary between a Cosserat-dominated regime of complete wave attenuation and an odd-elasticity-dominated regime of propagating waves. We conclude by showing the effect of Cosserat and odd elastic terms on the polarization of Rayleigh surface waves.

description: In the contracting phase with w\simeq 0, the scale invariant spectrum of curvature perturbation is given by the increasing mode of metric perturbation. In this paper, it is found that if the contracting phase with w\simeq 0 is included in each cycle of a cycle universe, since the metric perturbation is amplified on super horizon scale cycle by cycle, after each cycle the universe will be inevitably separated into many parts independent of one another, each of which corresponds to a new universe and evolves up to next cycle, and then is separated again. In this sense, a cyclic multiverse scenario is actually presented, in which the universe proliferates cycle by cycle. We estimate the number of new universes proliferated in each cycle, and discuss the implications of this result.

description: Employing unbiased sign-problem-free quantum Monte Carlo, we investigate the effects of long-range Coulomb forces on BEC of bipolarons using a model of bond phonon-modulated electron hopping. In absence of long-range repulsion, this model was recently shown to give rise to small-size, light-mass bipolarons that undergo a superfluid transition at high values of the critical transition temperature $T_\mathrm{c}$. We find that $T_\mathrm{c}$ in our model even with the long-range Coulomb repulsion remains much larger than that of Holstein bipolarons, and can be on the order of or greater than the typical upper bounds on phonon-mediated $T_\mathrm{c}$ based on the Migdal-Eliashberg and McMillan approximations. Our work points to a physically simple mechanism for superconductivity in the low-density regime that may be relevant to current experiments on dilute superconductors.

description: We revisit the modal analysis of small perturbations in Keplerian ideal gas flows leading to magneto-rotational instability (MRI) using the non-local approach. We consider the case of constant vertical background magnetic field, as well as the case of radially dependent background Alfvén velocity. In the case of constant Alfvén velocity, MRI modes are described by a Schrödinger-like differential equation with some effective potential including 'repulsive' ($1/r^2$) and 'attractive' ($-1/r^3$) terms. Taking into account the radial dependence of the background Alfvén speed leads to a qualitative change in the shape of the effective potential. It is shown that there are no stationary energy levels corresponding to unstable modes $ω^2 < 0$ in ``shallow'' potentials. In thin accretion disks, the wavelength of the disturbance $λ=2π/k_z$ is smaller than the half-thickness $h$ of the disk only in ``deep'' potentials. The limiting value of the background Alfvén speed $(c_A)_\mathrm{cr}$, above which the magnetorotational instability does not occur, is found. In thin accretion disks with low background Alfvén speed $c_A\ll (c_A)_\mathrm{cr}$, the increment of the magnetorotational instability $ω\approx -\sqrt{3}\mathrm{i}c_Ak_z$ is suppressed compared to the value obtained in the local perturbation analysis.

description: Nonlinear Optical Spectroscopy is a well-developed field with theoretical and experimental advances that have aided multiple fields including chemistry, biology and physics. However, accurate quantum dynamical simulations based on model Hamiltonians are need to interpret the corresponding multi-dimensional spectral signals properly. In this article, we present the initial release of our code, QuDPy (quantum dynamics in python) which addresses the need for a robust numerical platform for performing quantum dynamics simulations based on model systems, including open quantum systems. An important feature of our approach is that one can specify various high-order optical response pathways in the form of double-sided Feynman diagrams via a straightforward input syntax that specifies the time-ordering of ket-sided or bra-sided optical interactions acting upon the time-evolving density matrix of the system. We use the quantum dynamics capabilities of QuTip for simulating the spectral response of complex systems to compute essentially any n-th-order optical response of the model system. We provide a series of example calculations to illustrate the utility of our approach.

description: We carried out zero-field muon-spin-rotation (ZF-$μ$SR) measurements in hydrostatic pressures in impurity-doped quantum spin gap system Tl(Cu$_{0.985}$Mg$_{0.015}$)Cl$_3$ to investigate microscopic magnetic properties of the pressure-induced phase. The spontaneous muon spin precession, which indicates the existence of a long-range coherent order, is observed in pressures. With decreasing temperature in 3.1 kbar, the internal static magnetic field at the muon sites {\it H}$_{\rm int}$ tends to saturate to 280 Oe around 4 K, however, decreases to 240 Oe at 2.3 K. These results suggest a rearrangement of ordered spins, and we speculate that the oblique antiferromagnetic phase, which is observed in the pressure of 14 kbar on the pure TlCuCl$_3$, appears in the Mg-doped system in lower pressures.

description: The tree of life (TOL) is severely threatened by climate and land-cover changes. Preserving the TOL is urgent, but has not been included in the post-2020 global biodiversity framework. Protected areas (PAs) are fundamental for biological conservation. However, we know little about the effectiveness of existing PAs in preserving the TOL of plants and how to prioritize PA expansion for better TOL preservation under future climate and land-cover changes. Here, using high-resolution distribution maps of 8732 woody species in China and phylogeny-based Zonation, we find that current PAs perform poorly in preserving the TOL both at the present and in 2070s. The geographical coverage of TOL branches by current PAs is ca 9%, and less than 3% of the identified priority areas for preserving the TOL are currently protected. Interestingly, the geographical coverage of TOL branches by PAs will be improved from 9 to 52–79% by the identified priority areas for PA expansion. Human pressures in the identified priority areas are high, leading to high cost for future PA expansion. We thus suggest that besides nature reserves and national parks, other effective area-based conservation measures should be considered. Our study argues for the inclusion of preserving the TOL in the post-2020 conservation framework, and provides references for decision-makers to preserve the Earth's evolutionary history.

description: We conduct the first large-scale user study examining how users interact with an AI Code assistant to solve a variety of security related tasks across different programming languages. Overall, we find that participants who had access to an AI assistant based on OpenAI's codex-davinci-002 model wrote significantly less secure code than those without access. Additionally, participants with access to an AI assistant were more likely to believe they wrote secure code than those without access to the AI assistant. Furthermore, we find that participants who trusted the AI less and engaged more with the language and format of their prompts (e.g. re-phrasing, adjusting temperature) provided code with fewer security vulnerabilities. Finally, in order to better inform the design of future AI-based Code assistants, we provide an in-depth analysis of participants' language and interaction behavior, as well as release our user interface as an instrument to conduct similar studies in the future.

description: Unhealthy dietary habits are considered as the primary cause of various chronic diseases, including obesity and diabetes. The automatic food intake monitoring system has the potential to improve the quality of life (QoL) of people with diet-related diseases through dietary assessment. In this work, we propose a novel contactless radar-based approach for food intake monitoring. Specifically, a Frequency Modulated Continuous Wave (FMCW) radar sensor is employed to recognize fine-grained eating and drinking gestures. The fine-grained eating/drinking gesture contains a series of movements from raising the hand to the mouth until putting away the hand from the mouth. A 3D temporal convolutional network with self-attention (3D-TCN-Att) is developed to detect and segment eating and drinking gestures in meal sessions by processing the Range-Doppler Cube (RD Cube). Unlike previous radar-based research, this work collects data in continuous meal sessions (more realistic scenarios). We create a public dataset comprising 70 meal sessions (4,132 eating gestures and 893 drinking gestures) from 70 participants with a total duration of 1,155 minutes. Four eating styles (fork & knife, chopsticks, spoon, hand) are included in this dataset. To validate the performance of the proposed approach, seven-fold cross-validation method is applied. The 3D-TCN-Att model achieves a segmental F1-score of 0.896 and 0.868 for eating and drinking gestures, respectively. The results of the proposed approach indicate the feasibility of using radar for fine-grained eating and drinking gesture detection and segmentation in meal sessions.

description: In parallel to the condensed-matter realization of quantum Hall (Chern insulators), quantum spin Hall (topological insulators), and fractional quantum Hall (fractional Chern insulators) effects, we propose that bilayer flat band (FB) lattices with one FB in each layer constitute solid-state analogues of bilayer quantum Hall (BQH) system, leading to anomalous BQH (ABQH) effect, without magnetic field. By exact diagonalization of a bilayer Kagome lattice Hamiltonian, as a prototypical example, we demonstrate the stabilization of excitonic condensate Halperin's (1,1,1) state at the total filling $v_T=1$ of the two Fbs. Furthermore, by tuning the inter-layer tunneling and distance between the Kagome layers at $v_T=2/3$, we show phase transitions among Halperin's (3,3,0), spin-singlet (1,1,2), and particle-hole conjugate of Laughlin's 1/3 states, as previously observed in BQH systems. Our work opens a new research direction in the field of FB physics by demonstrating bilayer FB materials as an attractive avenue for realizing exotic ABQH states including non-Abelian anyons.

Interestingly, the geographical coverage of TOL branches by PAs will be improved from 9 to 52–79% by the identified priority areas for PA expansion. Human pressures in the identified priority areas are high, leading to high cost for future PA expansion. We thus suggest that besides nature reserves and national parks, other effective area-based conservation measures should be considered. Our study argues for the inclusion of preserving the TOL in the post-2020 conservation framework, and provides references for decision-makers to preserve the Earth's evolutionary history.

description: Neural or cortical fields are continuous assemblies of mesoscopic models, also called neural masses, of neural populations that are fundamental in the modeling of macroscopic parts of the brain. Neural fields are described by nonlinear integro-differential equations. The solutions of these equations represent the state of activity of these populations when submitted to inputs from neighbouring brain areas. Understanding the properties of these solutions is essential in advancing our understanding of the brain. In this paper we study the dependency of the stationary solutions of the neural fields equations with respect to the stiffness of the nonlinearity and the contrast of the external inputs. This is done by using degree theory and bifurcation theory in the context of functional, in particular infinite dimensional, spaces. The joint use of these two theories allows us to make new detailed predictions about the global and local behaviours of the solutions. We also provide a generic finite dimensional approximation of these equations which allows us to study in great details two models. The first model is a neural mass model of a cortical hypercolumn of orientation sensitive neurons, the ring model. The second model is a general neural field model where the spatial connectivity isdescribed by heterogeneous Gaussian-like functions.

description: Im Folgenden soll eine neue ikonografische Deutung des Gemäldes ‚Das Martyrium des Apostels Matthäus‘ erstellt werden, in der das Martyrium als Darstellungsproblem in den Blick gerät. Einer knappen Vorstellung der bisherigen Interpretationen folgt eine formale Beschreibung und Bestimmung des Mörders als der verborgenen ‚clavis interpretandi‘ des Bildes, die zu einer Neubewertung der sich ereignenden Handlung führt. Der Aspekt des Beitrags betrifft dabei weniger die Vorbilder des Malers als vielmehr seine implizite Kritik des katholischen Bilderkults und dessen Behandlung der Martyriums-Idee.

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.
A visual investigation of fetish in contemporary society
Creators: name: McGowan, SM
Publisher: name: University Of Tasmania
Year: 2023

description: This project is a visual investigation of fetish in contemporary society, developed through the selection and representation of collected objects, with a particular focus on toys. Various definitions of fetish are explored through its development in the modem world, from its first use to describe a religious object in the fifteenth century, to the use of the term fetish in an economic sense by Karl Marx, and to the use of fetish in a psychological sense by Sigmund Freud. Contemporary understanding of the term fetish is further developed to explore the role that the readymade object plays in society as described by cultural theorist William Pietz. A context in Fine Art is offered historically through Andy Warhol and his repetitions of popular culture iconography, and in a more contemporaneous sense by the work of Zoe Leonard, Wolfgang Laib and the Chapman Brothers. This investigation is carried out through the production and presentation of sculpture. Objects are sourced from the everyday world; manipulated, and represented to explore and develop ideas about the role that fetish plays in the contemporary world. Objects that are sourced for this project are chosen to explore the changing and varied definition of fetish. These include objects of mass consumption and advertising such as commercial toys, spiritual or religious objects such as icons or statues, and objects that are regarded as having a more contemporary and personal sense of fetish. Fetish is shown through the project to be a valid descriptor of certain relationships to objects in the world. Toys were used to drive an investigation of fetish throughout the project, and fulfil the definitions of what fetish might be. The project has shown that fetish is a term that can be widely used in culture to describe relationships to objects.
A study of dramatic structure in Harold Pinter's stage plays
Creators: name: Parkin, Christine Patricia
Publisher: name: University of British Columbia
Year: 2012

description: Pinter has said that his main concern when writing a play is with structure, yet published criticism has so far paid little attention to this aspect of his craft. This study, therefore, examines the structures of Pinter's stage plays. The method followed is a chronological structural analysis moving from The Room through The Birthday Party, The Dumb Waiter, The Caretaker, The Homecoming, Landscape and Silence to his latest play, Old Times, first produced in London on June 1, 1971- The opening chapter discusses the terms which form a background to the subsequent description of the dramatic structures. The analyses demonstrate that there are at least three major features of his craftsmanship to emerge at this point in his career. The first is that where as the stage plays up to the writing of Landscape share a common, almost traditionally sequential narrative structure, the three latest plays, Landscape, Silence and Old Times, have differently shaped structures relying heavily on the exploration of memory and abandoning a normal sequential ordering of incident. This marked change implies a different use of time which is the second major feature, and is a consequence of the exploration of the past. It is accompanied in Landscape and Silence by a shift from dialogue in the previous plays to an almost exclusive reliance on monologue. Pinter also moves from his earlier comic-grotesque manner to a cooler, more subdued mode which uses lyrical and elegiac language. The third major feature of his craftsmanship is a certain rhythm of structure. This is a tendency to elaborate a one-act form into a larger structure, and then to take some feature or concern from previous work, paring down and compressing to make another one-act play, before building up and elaborating once more. Thus The Room is followed by the larger, three act structure of The Birthday Party to accommodate additional concerns. The Dumb Waiter shows the paring down process before the structural expansion in The Caretaker. The Homecoming, with its tighter two-act structure, is centrally placed, looking back to previously explored themes and anticipating the concern with memory in the three latest works. In the one-act Landscape Pinter abandons horizontal for vertical structure, explores cyclic rather than sequential time and uses monologue rather than dialogue. Silence illustrates a further paring down process in its even more austere denial of theatricality before the renewed building up process discernible in the two-act play, Old Times.
Microscopic description of heavy ion collisions around the barrier

description: A microscopic mean-field description of heavy ion collisions is performed in the framework of the time dependent Hartree-Fock theory using a Skyrme energy density functional. A good agreement with experiments is obtained on the position of the fusion barriers for various total masses and mass asymmetries. The excitation function of the 16O+208Pb is overestimated by about 16% above the barrier. Transfer below the barrier is studied in 16O+208Pb central collisions. Heavier systems are considered to study their fusion hindrance. We also compute collision times of the 238U+238U system. The latter has been used to produce super strong electric fields and to test non perturbative quantum electrodynamics theory. Indeed, if the life time of such giant system is of the order of few 10^-21 s, its electric field should induce spontaneous electron-positron pair emissions from vacuum. In our calculations, highest collision times are reached in the 238U+238U reaction for center of mass energies between 1000 and 1300 MeV.

description: Der Begriff ‚Krise‘ ist allgegenwärtig im zeitgenössischen Diskurs. Mit der Interpretation von Geschehnissen als krisenhaft ist es möglich, dass bestimmte Bezugspunkte und Handlungsoptionen verschlossen werden, da die Krise zum Platzhalter für heterogene Prozesse wird. Inmitten der Interkonnektivität des ubiquitären Krisengeschehens können künstlerische Ansätze eine erkenntnisbereichernde Funktion einnehmen, da sie Verbindungslinien ziehen, die sonst in voneinander getrennten Krisen verbleiben würden. In diesem Aufsatz wird zur Untersuchung dessen eine recherchebasierte Arbeit des britischen Kollektivs Forensic Architecture herangezogen, die eine Vielzahl von Krisen und ihre Vernetzungen in der neuen Erdepoche des Anthropozäns offenlegt.
