Food for thought : a visual investigation of the nature-culture dichotomy as manifested in 'farm' animals
Creators: name: Watt, Yvette
Publisher: name: University Of Tasmania
Year: 2023

description: The project has involved the production of artworks that explore our relationship to 'farm' animals within increasingly urban Western societies. The investigation proposes that farm animals, whose form is continuously changed by human intervention, bridge the nature-culture dichotomy, as they are seen simultaneously as natural and 'man-made'. The issues were approached through analysis and quotation of popular forms of representation of farm animals such as plastic models and photographs. These objects and images, which inform our understanding of and relationship to these animals from an early age, manifest the transformation of the animal from nature to culture. The use of secondary sources of imagery also allowed for explorations of the relationship between depiction and understanding, whereby the manner in which the animal is represented might be seen to reflect a society's attitudes towards the animal. The objective resulted in a suite of works that reflect the complexity of this dichotomy and the conventions on which it is based. This research has as its background an abiding interest in human-animal relationships and the representation of animals in art and popular culture; and reflects a specific concern about urban societies' growing distance from, and attendant ignorance of, the lives of farmed 'food' animals. The research also acknowledges the long tradition of animal painting; a tradition that has for some time been relegated to a lowly position within the hierarchy of important subject matter for artists. It is argued in the exegesis that, although there has been something of a resurgence of interest in animals as subject matter within contemporary art, this interest rarely extends to farm animals. The project seeks to redress this imbalance through art works that encourage the viewer to question their understanding of these animals and their relationship to them. The final body of work is in the form of oil paintings based on photographs of crude, mass-produced plastic models of farm animals. The layered artificiality of these paintings of mutant-looking models reflects the described, detached, objectified human/farm-animal relationship while also alluding to the continual modification of the form of these animals through selective breeding and genetic engineering.

description: First Rosenblatt's theorem about omnipotence of shallow networks states that elementary perceptrons can solve any classification problem if there are no discrepancies in the training set. Minsky and Papert considered elementary perceptrons with restrictions on the neural inputs: a bounded number of connections or a relatively small diameter of the receptive field for each neuron at the hidden layer. They proved that under these constraints, an elementary perceptron cannot solve some problems, such as the connectivity of input images or the parity of pixels in them. In this note, we demonstrated first Rosenblatt's theorem at work, showed how an elementary perceptron can solve a version of the travel maze problem, and analysed the complexity of that solution. We constructed also a deep network algorithm for the same problem. It is much more efficient. The shallow network uses an exponentially large number of neurons on the hidden layer (Rosenblatt's $A$-elements), whereas for the deep network the second order polynomial complexity is sufficient. We demonstrated that for the same complex problem deep network can be much smaller and reveal a heuristic behind this effect.

description: In the field of public health, treatment of multidrug-resistant (MDR) bacterial infection is a great challenge. Herein, we provide a solution to this problem with the use of graphene oxide-silver (GO-Ag) nanocomposites as antibacterial agent. Following established protocols, silver nanoparticles were grown on graphene oxide sheets. Then, a series of in vitro studies were conducted to validate the antibacterial efficiency of the GO-Ag nanocomposites against clinical MDR Escherichia coli (E. coli) strains. GO-Ag nanocomposites showed the highest antibacterial efficiency among tested antimicrobials (graphene oxide, silver nanoparticles, GO-Ag), and synergetic antibacterial effect was observed in GO-Ag nanocomposites treated group. Treatment with 14.0 µg ml−1 GO-Ag treatment could greatly inhibit bacteria growth; remaining bacteria viabilities were 4.4% and 4.1% for MDR-1 and MDR-2 E. coli bacteria, respectively. In addition, with assistance of photothermal effect, effective sterilization could be achieved using GO-Ag nanocomposites as low as 7.0 µg ml−1. Fluorescence imaging and morphology characterization uncovered that bacteria integrity was disrupted after GO-Ag nanocomposites treatment. Cytotoxicity results of GO-Ag using human-derived cell lines (HEK 293T, Hep G2) suggested more than 80% viability remained at 7.0 µg ml−1. All the results proved that GO-Ag nanocomposites are efficient antibacterial agent against multidrug-resistant E. coli.
Search for displaced photons produced in exotic decays of the Higgs boson using 13 TeV $pp$ collisions with the ATLAS detector

Year: 2022
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A search is performed for delayed and nonpointing photons originating from the displaced decay of a neutral long-lived particle (LLP). The analysis uses the full Run 2 data set of proton-proton collisions delivered by the LHC at a center-of-mass energy of $\sqrt{s}=13$ TeV between 2015 and 2018 and recorded by the ATLAS detector, corresponding to an integrated luminosity of 139 fb$^{-1}$. The capabilities of the ATLAS electromagnetic calorimeter are exploited to precisely measure the arrival times and trajectories of photons. The results are interpreted in a scenario where the LLPs are pair-produced in exotic decays of the 125 GeV Higgs boson, and each LLP subsequently decays into a photon and a particle that escapes direct detection, giving rise to missing transverse momentum. No significant excess is observed above the expectation due to Standard Model background processes. The results are used to set upper limits on the branching ratio of the exotic decay of the Higgs boson. A model-independent limit is also set on the production of photons with large values of displacement and time delay.

description: Combining the construction of integrable systems of hydrodynamic type starting from the Frölicher-Nijenhuis bicomplex $(d,d_L)$ associated with a (1,1)-tensor field $L$ with vanishing Nijenhuis torsion with the construction of flat structures starting from integrable systems of hydrodynamic type we define multi-parameter families of bi-flat structures $(\nabla,e,\circ,\nabla^*,*,E)$ associated with Frölicher-Nijenhuis bicomplexes. We call these structures Lauricella bi-flat structures since in the n-dimensional semisimple case (n-1) flat coordinates of r are Lauricella functions.

description: We present infrared JHK photometry of the cataclysmic variable SDSS J123813.73-033933.0 (SDSS1238)and analyze it along with optical spectroscopy, demonstrating that the binary system is most probably comprised of a massive white dwarf with Teff=12000+/-1000 K and a brown dwarf of spectral type L4. The inferred system parameters suggest that this system may have evolved beyond the orbital period minimum and is a bounce-back system. SDSS1238 stands out among CVs by exhibiting the cyclical variability (brightenings). These are not related to specific orbital phases of the binary system and are fainter than dwarf novae outbursts, that usually occur on longer timescales. This phenomenon has not been observed extensively and, thus, is poor understood. The new time-resolved, multi-longitude photometric observations of SDSS1238 allowed us to observe two consecutive brightenings and to determine their recurrence time. The period analysis of all observed brightenings during 2007 suggests a typical timescale that is close to a period of ~9.3 hours. However, the brightenings modulation is not strictly periodic, possibly maintaining coherence only on timescales of several weeks. The characteristic variability with double orbital frequency that clearly shows up during brightenings is also analyzed. The Doppler mapping of the system shows the permanent presence of a spiral arm pattern in the accretion disk. A simple model is presented to demonstrate that spiral arms in the velocity map appear at the location and phase corresponding to the 2:1 resonance radius and constitute themselves as a double-humped light curves. The long-term and short-term variability of this CV is discussed together with the spiral arm structure of an accretion disk in the context of observational effects taking place in bounce-back systems.

The formation of cliques in collectivities as a consequence of initial distributions of dimensions of wealth
Creators: name: Foddy, William Henry
Publisher: name: University of British Columbia
Year: 2012

description: Past approaches to the understanding of the occurrence of exchange Interactions and the generation of sentiments of social approval and social disapproval within collectivities are reviewed and a new theory is formulated. The new theory focuses on initial, unequal distributions of dimensions of wealth within the collectivities . On the basis of knowledge about the differences between the members' net wealth levels, four hypotheses regarding the patterns of exchange interactions in the collectivities are derived for testing. These hypotheses concern: ( i ) the emergence, and order of emergence, of cliques within the collectivities, and ( i i ) the generation of sentiments of approval between fellow clique members and sentiments of disapproval between the members of the different cliques in each collectivity. An experimental paradigm is then described and the results of actual, laboratory experiments presented. It is concluded that all four hypotheses are supported by the data. Finally, the theory is placed within the wider context of the sociology of social stratification in general.

description: The equations of motion for a conformal field theory in the presence of defect lines can be derived from an action that includes contributions from bibranes. For T-dual toroidal compactifications, they imply a direct relation between Poincare line bundles and the action of T-duality on boundary conditions. We also exhibit a class of diagonal defects that induce a shift of the B-field. We finally study T-dualities for S^1-fibrations in the example of the Wess-Zumino-Witten model on SU(2) and lens spaces. Using standard techniques from D-branes, we derive from algebraic data in rational conformal field theories geometric structures familiar from Fourier-Mukai transformations.

description: We extend the result of Lisini (Calc Var Partial Differ Equ 28:85-120, 2007) on the superposition principle for absolutely continuous curves in $p$-Wasserstein spaces to the special case of $p=1$. In contrast to the case of $p>1$, it is not always possible to have lifts on absolutely continuous curves. Therefore, one needs to relax the notion of a lift by considering curves of bounded variation, or shortly BV-curves, and replace the metric speed by the total variation measure. We prove that any BV-curve in a 1-Wasserstein space can be represented by a probability measure on the space of BV-curves which encodes the total variation measure of the Wasserstein curve. In particular, when the curve is absolutely continuous, the result gives a lift concentrated on BV-curves which also characterizes the metric speed. The main theorem is then applied for the characterization of geodesics and the study of the continuity equation in a discrete setting.

title: Pipeline-backfill-trench interaction during large lateral displacements
Creators: name: Kianian, Morteza
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Subsea pipelines, particularly in shallow areas, are usually buried inside trenches backfilled with pre-excavated material as cost-effective protection against the environmental, constructional, and operational loads. The design of buried pipelines against potential lateral displacements is a challenging task that is usually simplified by assuming a uniform soil surrounding the pipeline. However, the remolded backfill and its lower stiffness compared with the native ground can significantly affect the failure mechanisms around the moving pipe and the mobilized lateral soil resistance. Having a trench backfilled with a material softer than the native seabed soil will lead to a complicated pipe-soil interaction problem which has not been entirely explored in the literature. In this study, the lateral pipeline-backfill-trench interaction and the resultant soil failure mechanisms were investigated by centrifuge models (in partially drained conditions) and also numerical simulations (in undrained conditions). Particle image velocimetry (PIV) analysis was conducted to capture the interactive soil displacements and failure mechanisms during centrifuge tests. It was observed that the interactive effects of pipeline, backfill, and trench precede their individual shear strengths. The advanced numerical simulations were developed by using the Coupled Eulerian-Lagrangian (CEL) approach with two different Eulerian materials behaving in undrained conditions. The numerical simulations in undrained conditions show a good agreement with the previously conducted centrifuge tests in terms of lateral load-displacement response and failure mechanisms. The investigated parameters are pipe roughness, pipe weight, pipe initial embedment into the trench-bed, backfill strength properties, soil strain-softening, native soil tension cut-off, and burial depth. The effects of influential parameters are comprehensively examined using the developed numerical model, and the results show good agreement with some previously conducted centrifuge tests. The study revealed the significance of the pipeline-trenchbed interaction in the mobilization of the lateral soil resistance and several other mechanisms not yet addressed in the literature. As a result, several new research avenues were identified, and the ground was prepared for proposing solutions to improve the prediction of the lateral response of buried pipelines in the near future.

description: Recently, Gorban (2021) analysed some kinetic paradoxes of the transition state theory and proposed its revision that gave the "entangled mass action law", in which new reactions were generated as an addition to the reaction mechanism under consideration. These paradoxes arose due to the assumption of quasiequilibrium between reactants and transition states. In this paper, we provided a brief introduction to this theory, demonstrating how the entangled mass action law equations can be derived in the framework of the standard quasi steady state approximation in combination with the quasiequilibrium generalized mass action law for an auxiliary reaction network including reactants and intermediates. We also proved the basic physical property (positivity) for these new equations, which was not obvious in the original approach.

description: This research project explores themes of remembrance, place and identity from ideas established by philosophers such as Cicero, Quintilian and Proust, and scholars including Susan Stewart, Michael Perlman and Francis Yates. These perspectives are developed into a body of artwork created from miniatures and video that reference autobiographical memories of my father's stay and passing in a palliative care hospice. Particular narratives are translated through still and moving images by constructing a Memory Palace through a video installation. The display of artwork creates a mnemonic relationship that is supported by the philosophical perspectives and contentions established throughout the investigation. The contributions of contemporary artists Ricky Swallow, Janet Cardiff, Jake and Dinos Chapman, John Timberlake, Thomas Hirschorn and Michael Ashkins are examined in relation to the nature of the project and its contribution to contemporary art. The outcomes of the project are two-fold. Firstly, the body of artwork will demonstrate a link between scale and memory. Secondly, the written exegesis informs the artwork by establishing historical and philosophical perspectives relevant to the project.

description: We study the transport properties of disordered two-dimensional electron systems with a perfectly conducting channel. We introduce an asymmetric Chalker-Coddington network model and numerically investigate the point-contact conductance. We find that the behavior of the conductance in this model is completely different from that in the symmetric model. Even in the limit of a large distance between the contacts, we find a broad distribution of conductance and a non-trivial power law dependence of the averaged conductance on the system width. Our results are applicable to systems such as zigzag graphene nano-ribbons where the numbers of left-going and right-going channels are different.

Why become an Archaeologist?
Creators: name: Bowen, Helen
Publisher: name: Archaeology Data Service
Year: 2014

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.
Discerning goods : an exposition of the ethical theory of John Anderson
Creators: name: Volpato, Ros
Publisher: name: University Of Tasmania
Year: 2023

description: This essay explores the possibility of a scientific theory of ethics by an examination of the writings of John Anderson. Anderson holds the view that the diversity of theories in ethics is not because there are a large number of subject matters in ethics, but rather that there are a large number of theories attempting to explain one set of ethical phenomena.I The ethical field is confused, for the very nature of this field is not adequately grasped. The partiality of the resulting views leads to a search for 'foundations' that aim to prop up what was never properly constructed or realised. Thus Anderson's approach here, as elsewhere, is polemical and critical.

description: Recommender systems are expected to be assistants that help human users find relevant information automatically without explicit queries. As recommender systems evolve, increasingly sophisticated learning techniques are applied and have achieved better performance in terms of user engagement metrics such as clicks and browsing time. The increase in the measured performance, however, can have two possible attributions: a better understanding of user preferences, and a more proactive ability to utilize human bounded rationality to seduce user over-consumption. A natural following question is whether current recommendation algorithms are manipulating user preferences. If so, can we measure the manipulation level? In this paper, we present a general framework for benchmarking the degree of manipulations of recommendation algorithms, in both slate recommendation and sequential recommendation scenarios. The framework consists of four stages, initial preference calculation, training data collection, algorithm training and interaction, and metrics calculation that involves two proposed metrics. We benchmark some representative recommendation algorithms in both synthetic and real-world datasets under the proposed framework. We have observed that a high online click-through rate does not necessarily mean a better understanding of user initial preference, but ends in prompting users to choose more documents they initially did not favor. Moreover, we find that the training data have notable impacts on the manipulation degrees, and algorithms with more powerful modeling abilities are more sensitive to such impacts. The experiments also verified the usefulness of the proposed metrics for measuring the degree of manipulations. We advocate that future recommendation algorithm studies should be treated as an optimization problem with constrained user preference manipulations.

description: Reheating is an important part of inflationary cosmology. It describes the production of Standard Matter particles after the phase of accelerated expansion. We give a review of the reheating process, focusing on an in-depth discussion of the preheating stage which is characterized by exponential particle production due to a parametric resonance or tachyonic instability. We give a brief overview of the thermalization process after preheating and end with a survey of some applications to supersymmetric theories and to other issues in cosmology such as baryogenesis, dark matter and metric preheating.

description: Feedback is a powerful and ubiquitous technique both in classical and quantum system control. Its standard implementation relies on measuring the state of a system, processing the classical signal, and feeding it back to the system. In quantum physics, however, measurements not only read out the state of the system but also modify it irreversibly. Coherent feedback is a different kind of feedback that coherently processes and feeds back quantum signals without actually measuring the system. Here, we report on the experimental realization and the theoretical analysis of an optical coherent feedback platform to control the motional state of a nanomechanical membrane in an optical cavity. The coherent feedback loop consists of a light field interacting twice with the same mechanical mode through different cavity modes, without {performing any} measurement. Tuning the optical phase and delay of the feedback loop allows us to control the motional state of the mechanical oscillator, its resonance frequency and also its damping rate, which we use to cool the membrane close to the quantum ground state. Our theoretical analysis provides the optimal cooling conditions, showing that this new technique enables ground-state cooling. Experimentally, we show that we can cool the membrane to a state with $\bar{n}_m = 4.89 \pm 0.14 $ phonons (${480}\,{μ\mathrm{K}}$) in a ${20}\,\mathrm{K}$ environment. This lies below the theoretical limit of cavity dynamical backaction cooling in the unresolved sideband regime and is achieved with only 1$\%$ of the optical power required for cavity cooling. Our feedback scheme is very versatile, offering new opportunities for quantum control in a variety of optomechanical systems.
