description: Creating single photons in the telecommunication wavelength range from semiconductor quantum dots (QDs) and interfacing them with spins of electrons or holes has been of high interest in recent years, with research mainly focusing on indium based QDs. However, there is not much data on the optical and spin properties of galliumantimonide (GaSb) QDs, despite it being a physically rich system with an indirect to direct bandgap crossover in the telecom wavelength range. Here, we investigate the (quantum-) optical properties of GaSb quantum dots, which are fabricated by filling droplet-etched nanoholes in an aluminum-galliumantimonide (AlGaSb) matrix. We observe photoluminescence (PL) features from isolated and highly symmetric QDs that exhibit narrow linewidth in the telecom S-band and show an excitonic fine structure splitting of $ΔE=(12.0\pm0.5)μeV$. Moreover, we perform time-resolved measurements of the decay characteristics of an exciton and measure the second-order photon autocorrelation function of the charge complex to $g^{(2)}(0)=0.16\pm0.02$, revealing clear antibunching and thus proving the capability of this material platform to generate non-classical light.

description: Brown dwarf formation and star formation efficiency are studied using a nested grid simulation that covers five orders of magnitude in spatial scale (10^4 - 0.1AU). Starting with a rotating magnetized compact cloud with a mass of 0.22 M_sun, we follow the cloud evolution until the end of main accretion phase. Outflow of about 5 km/s emerges about 100 yr before the protostar formation and does not disappear until the end of the calculation. The mass accretion rate declines from 10^-6 M_sun/yr to 10^-8 - 10^-12 M_sun/yr in a short time (about 10^4 yr) after the protostar formation. This is because (1) a large fraction of mass is ejected from the host cloud by the protostellar outflow and (2) the gas escapes from the host cloud by the thermal pressure. At the end of the calculation, 74% (167 M_Jup) of the total mass (225 M_Jup) is outflowing from the protostar, in which 34% (77 M_Jup) of the total mass is ejected by the protostellar outflow with supersonic velocity and 40% (90 M_Jup) escapes with subsonic velocity. On the other hand, 20% (45 M_Jup) is converted into the protostar and 6% (13 M_Jup) remains as the circumstellar disk. Thus, the star formation efficiency is epsilon = 0.2. The resultant protostellar mass is in the mass range of brown dwarfs. Our results indicate that brown dwarfs can be formed in compact cores in the same manner as hydrogen-burning stars, and the magnetic field and protostellar outflow are essential in determining the star formation efficiency and stellar mass.

description: Scattering by atmospheric turbulence is one of the main challenges in creating long free-space optical links, and specifically links of entangled photons. Classical compensation methods are hard to apply to entangled photons, due to inherently low signal to noise ratios and the fragility of entanglement. We have recently shown that we can use the bright laser beam that pumps spontaneous parametric down conversion to control the spatial correlations between entangled photons for compensating their scattering. In this work, we apply the pump-shaping technique to compensate for scrambling of correlations between entangled photons that scatter by emulated atmospheric turbulence. We use a spatial light modulator and Kolmogorov's turbulence model to emulate atmospheric turbulence in the lab, and enhance the entangled photons' signal by a factor of fifteen using pump optimization. We show this for both static and dynamic emulated atmosphere, and demonstrate also the compensation of the scattering of a higher-order mode. Our results can open the door towards realizing free-space quantum links with entangled photons, used in applications such as quantum key distribution.
Accounting for SGARAs : has comparability and consistency been achieved?
Creators: name: Williams, Belinda
Publisher: name: University Of Tasmania
Year: 2023

description: The accounting standard, AASB 1037 'Accounting for self-generating and regenerating assets' (SGARAs) was introduced into the Australian financial reporting arena for the financial year ending 30 June 2001. Prior to the introduction of this standard, there was no regulatory guidance provided by the standard setters. With the adoption of international standards into Australia from 01 January 2005, AASB 1037 has effectively been replaced by its international equivalent, AASB 141 'Agriculture'. This study examines whether the objectives of consistency and comparability have been achieved through the implementation of AASB 103 7 and the subsequent adoption of AASB 141. A triangulated approach is adopted utilising mail survey and interview techniques to collect data. The results indicate that consistency in measurement methods has not been achieved by the introduction of a prescribed accounting method under AASB 1037 with firms utilising a variety of measurement methods. By not applying the same accounting methods, this has also impaired comparability between firms and across industries. Consistency was found to have been achieved through measurement methods having been applied consistently over time and the type of measurement methods being applied to three SGARAs, being grapes, native forests and plantation timber. In the case of AASB 141, conflicting results were received from the mail survey and interviews respectively. In terms of the application of AASB 141, it is too early to tell if consistency has been achieved.

description: In several large-scale replication projects, statistically non-significant results in both the original and the replication study have been interpreted as a "replication success". Here we discuss the logical problems with this approach: Non-significance in both studies does not ensure that the studies provide evidence for the absence of an effect and "replication success" can virtually always be achieved if the sample sizes are small enough. In addition, the relevant error rates are not controlled. We show how methods, such as equivalence testing and Bayes factors, can be used to adequately quantify the evidence for the absence of an effect and how they can be applied in the replication setting. Using data from the Reproducibility Project: Cancer Biology, the Experimental Philosophy Replicability Project, and the Reproducibility Project: Psychology we illustrate that many original and replication studies with "null results" are in fact inconclusive. We conclude that it is important to also replicate studies with statistically non-significant results, but that they should be designed, analyzed, and interpreted appropriately.

description: This paper suggests that philosophy tells us something about and of the world, mostly of our contemporary world, if we see it as a metamorphic world. Thus, in order to understand our world, I claim that philosophy needs to pose as an explicit question the problem of transformations, or of processes: in this way, transformation can be properly conceived. Then, my contribution aims to present a first “transformative” definition of five concepts or actions, as of some of their main implications or elements: to have an idea (Objective Idea, Subjective Idea, Invention-Idea); to express (to effectuate, to translate); to make experience (to sense, to feel, to imagine); to endeavor (to reorient, to persist); to conceive (to envision, to share). As an appendix, I give also a graphic representation of these five concepts.

description: We analyze the feasibility to estimate the stellar mass of galaxies by mid-infrared luminosities based on a large sample of galaxies cross-identified from $Spitzer$ SWIRE fields and SDSS spectrographic survey. We derived the formulae to calculate the stellar mass by using IRAC 3.6$μ$m and 4.5$μ$m luminosities. The mass-to-luminosity ratios of IRAC 3.6$μ$m and 4.5$μ$m luminosities are more sensitive to star formation history of galaxies than other factors, such as the intrinsic extinction, metallicity and star formation rate. To remove the affection from star formation history, we used g-r color to recalibrate the formulae and obtain a better result. It must be more careful to estimate the stellar mass of low metallicity galaxies using our formulae. Due to the emission from dust heated by hottest young stars, luminous infrared galaxies present higher IRAC 4.5 $μ$m luminosity compared to IRAC 3.6 $μ$m luminosity. For most of type-II AGNs, the nuclear activity can not enhance 3.6$μ$m and 4.5$μ$m luminosities compared with normal galaxies. The star formation in our AGN-hosting galaxies is also very weak, almost all of which are early-type galaxies.

The ecosystem : A conceptual framework for identifying the ecological implications of planning options
Creators: name: Powers, Michael Gerard
Publisher: name: University of British Columbia
Year: 2011

description: The current problem of environmental deterioration is the result of society's perceived independence from nature. Through adoption of a systems perspective, however, one recognizes the need to relate man to his natural environment. In particular the concept of the ecosystem provides a theoretical model that recognizes the complex interdependence of man, land, and living systems. The development and application of the ecosystem concept suggests a variety of necessary changes regarding the traditional view of man/environment relationships and their incorporation into the planning process. These changes include: (1) the necessity of recognizing the symbiotic relationship between man and land; (2) the development of a boundary-oriented view of ecosystem stability; and (3) the need to adopt a planning strategy involving small yet diverse interventions to provide alternatives of action, maximum diversity of public choice, and systems stability. In the present study the theoretical and practical aspects of the ecosystem concept are applied to a specific land-use planning problem study to determine: (1) man-other organisms-physical environment interrelations; (2) the ecological implications of alternative development proposals upon those relationships; and (3) proposals for a comprehensive land-use plan recognizing the integrity of the ecosystem.

Sequantial large momentum transfer exploiting rectangular Raman pulses

Publisher: name: arXiv
Year: 2023
Subjects: subject: Atomic Physics (physics.atom-ph)

description: It is proposed to use rectangular Raman pulses for the technique of sequantial large momentum transfer. It is shown that the small parameters that make it possible to use this technology for precision atom interferometry can be 40--200 times smaller than in the case of the Bragg regime. It is predicted that in the case of a non-equidistant timing of auxiliary pulses, one can observe oscillations in time of the interference picture with a period inversely proportional to the recoil frequency. Such an observation would be the first confirmation that Mach-Zehnder atom interference is a phenomenon caused by the quantization of the atomic center-of-mass motion. This effect is calculated for any shape of pulses. One can observe it in the Bragg regime as well. It is proposed to use non-continuous composite Raman pulses as auxiliary beam splitters so that the effective Rabi frequency remains unchanged for the entire process. The gravity phase of an atomic interferometer is calculated for any shape, duration, and timing of Raman pulses, including the Bragg regime. The phase corrections caused by the finite pulses' durations are also calculated for rectangular Raman pulses shape.

description: Cuspidal robots can travel from one inverse kinematic solution to another without meeting a singularity. The name cuspidal was coined based on the existence of a cusp point in the workspace of 3R serial robots. The existence of a cusp point was proved to be a necessary and sufficient condition for orthogonal robots to be cuspidal, but it was not possible to extend this condition to non-orthogonal robots. The goal of this paper is to prove that this condition stands for any generic 3R robot. This result would give the designer more flexibility. In the presented work, the geometrical interpretation of the inverse kinematics of 3R robots is revisited and important observations on the nonsingular change of posture are noted. The paper presents a theorem regarding the existence of reduced aspects in any generic 3R serial robot. Based on these observations and on this theorem, we prove that the existence of a cusp point is a necessary and sufficient condition for any 3R generic robot to be cuspidal.

description: Modular quantum computing architectures are a promising alternative to monolithic QPU (Quantum Processing Unit) designs for scaling up quantum devices. They refer to a set of interconnected QPUs or cores consisting of tightly coupled quantum bits that can communicate via quantum-coherent and classical links. In multi-core architectures, it is crucial to minimize the amount of communication between cores when executing an algorithm. Therefore, mapping a quantum circuit onto a modular architecture involves finding an optimal assignment of logical qubits (qubits in the quantum circuit) to different cores with the aim to minimize the number of expensive inter-core operations while adhering to given hardware constraints. In this paper, we propose for the first time a Quadratic Unconstrained Binary Optimization (QUBO) technique to encode the problem and the solution for both qubit allocation and inter-core communication costs in binary decision variables. To this end, the quantum circuit is split into slices, and qubit assignment is formulated as a graph partitioning problem for each circuit slice. The costly inter-core communication is reduced by penalizing inter-core qubit communications. The final solution is obtained by minimizing the overall cost across all circuit slices. To evaluate the effectiveness of our approach, we conduct a detailed analysis using a representative set of benchmarks having a high number of qubits on two different multi-core architectures. Our method showed promising results and performed exceptionally well with very dense and highly-parallelized circuits that require on average 0.78 inter-core communications per two-qubit gate.

The ontological trait of the plasticity of the subject shows us that the Self is a continuous metamorphic activity, which is properly an activity of individualization of the identity of the Self. Following its natural metamorphic way of being and searching for its identity, the Self is revealed to be a transindividual form of life, constituting in the relationship with other transindividual forms of life and their counter-intentionality.

description: The entropy of a Schwarzschild black hole, as computed via the semiclassical Euclidean path integral in a stationary phase approximation, is determined not by the on-shell value of the action (which vanishes), but by the Gibbons--Hawking--York boundary term evaluated on a suitable hypersurface, which can be chosen arbitrarily far away from the horizon. For this reason, the black hole singularity seemingly has no influence on the Bekenstein--Hawking area law. In this Essay we estimate how a regular black hole core, deep inside a Euclidean black hole of mass $M$ and generated via a UV regulator length scale $\ell > 0$, affects the black hole entropy. The contributions are suppressed by factors of $\ell/(2GM)$; demanding exact agreement with the area law as well as a self-consistent first law of black hole thermodynamics at all orders, however, demands that these contributions vanish identically via uniformly bounded curvature. This links the limiting curvature hypothesis to black hole thermodynamics.

The nature of Tasmanian residence
Creators: name: White, Anthony Daryl
Publisher: name: University Of Tasmania

description: Since their original settlement, European Tasmanians have dramatically transformed the landscape. The British found, in an ancient environment largely unaltered since the division of Gondwana Land, the southernmost indigenous culture of the world. No man, plant or animal on the land was unaffected by the colonial project. Sadly, this has meant the demise of many endemic species of flora and fauna and, most regrettably, the demise of the full-blooded Tasmanian Aboriginal. Alongside the Europeans' perceived entitlement to claim the discovered land was a conviction that European Tasmanians also had the right to exploit the natural environment for individual purposes. My work contends that some of the colonial attitudes that validated the squander of natural resources and disrespect for human existence are still evident. There is an antagonistic social relationship between Tasmanians who believe in the value of the conserved natural environment and those whose livelihood relies on the resource-based extractive industries in the State. To illustrate how modern social attitudes are connected to the early colonisation process these relationships will be investigated within the visual work. In Tasmania, the environment is deeply associated with all aspects of the modern identity and the way of life. For this reason, the environment remains the paramount Tasmanian icon. My research project examines the Tasmanian environment as a subject with which to analyse, address and project a Tasmanian identity.

The exact relationship of the quasi-classical approximation to NEGF is demonstrated using Feynman diagrams of the nonlinear self energies. To leading order, the retarded self energies agree, but QMD and NEGF differ in lesser/greater self energies. An implementation for general systems using Cholesky decomposition of the correlated noises is discussed. Some means of stabilizing the dynamics are given. Thermal conductance results for graphene strips under strain and temperature dependence of carbon nanotubes are presented. The "quantum correction" method is critically examined.

description: Fluids confined within narrow channels exhibit a variety of phases and phase transitions associated with their reduced dimensionality. In this review paper, we illustrate the crossover from quasi-one dimensional to higher effective dimensionality behavior of fluids adsorbed within different carbon nanotubes geometries. In the single nanotube geometry, no phase transitions can occur at finite temperature. Instead, we identify a crossover from a quasi-one dimensional to a two dimensional behavior of the adsorbate. In bundles of nanotubes, phase transitions at finite temperature arise from the transverse coupling of interactions between channels.

Personal safety and security in regards to international students at University of Tasmania, Hobart
Creators: name: Yeh, J
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of this study was to see whether international students felt safe to live in Hobart, Tasmania. The hypothesis of this study was that some of the international students have obtained a bad impression about their safety and security while they live in Hobart, Tasmania. In order to research this, the study used a survey questionnaire. The survey questionnaire allowed international students to make any comments or give any impressions about their safety and security. The survey questionnaire has been put up on the Survey Monkey website. It does not identify who answered the survey questions. The survey questionnaire was divided into four parts. The four parts of this study were general information, personal safety and security issues, perceptions of safety, and making things safer. The purpose of the survey questionnaire was given broad ideas about how safe the international students. This dissertation provides a review on background literature about the problem and reports the research on the survey. This showed that international students in Hobart are concerned about the issue. The last chapter makes some recommendations.

description: We derive ground state eigenfunctions and eigenvalues of various relativistic elliptic integrable models. The models we discuss appear in computations of superconformal indices of four-dimensional theories obtained by compactifying six-dimensional models on Riemann surfaces. These include, among others, the Ruijsenaars-Schneider model and the van Diejen model. The derivation of the eigenfunctions builds on physical inputs, such as conjectured Lagrangian across dimensions IR dualities and assumptions about the behavior of the indices in the limit of compactifications on surfaces with large genus/number of punctures/flux.

The signature of galaxy formation models in the power spectrum of the hydrogen 21cm line during reionization

description: Observations of the 21cm line of neutral hydrogen are poised to revolutionize our knowledge of cosmic reionization and the high-redshift population of galaxies. However, harnessing such information requires robust and comprehensive theoretical modeling. We study the non-linear effects of hydrodynamics and astrophysical feedback processes, including stellar and AGN feedback, on the 21cm signal by post-processing three existing cosmological hydrodynamical simulations of galaxy formation: Illustris, IllustrisTNG, and Eagle. Overall and despite their different underlying galaxy-formation models, the three simulations return similar predictions for the global 21cm rightness temperature and its power spectrum. At fixed redshift, most differences are attributable to differences in the history of reionization, in turn driven by differences in the build-up of stellar sources of radiation. However, the impact of astrophysics is imprinted in the 21cm power spectrum through several unique signatures. First, we find significant small scale ($k \geq 10\, \rm {Mpc}^{-1}$) differences between Illustris and IllustrisTNG, where higher velocity winds generated by supernova feedback soften density peaks and lead to lower 21cm power in TNG. Second, we find more 21cm power at intermediate scales ($k \approx 0.8\, \rm {Mpc}^{-1}$) in Eagle, due to differences in ionization driven by highly effective stellar feedback, leading to lower star formation, older and redder stellar populations, and thus lower ionizing luminosities. Though subtle, these features could allow future observations of the 21cm signal, in conjunction with other reionization observables, to constrain theoretical models for galactic feedback at high redshift.

Complementary Classifier Induced Partial Label Learning

description: In partial label learning (PLL), each training sample is associated with a set of candidate labels, among which only one is valid. The core of PLL is to disambiguate the candidate labels to get the ground-truth one. In disambiguation, the existing works usually do not fully investigate the effectiveness of the non-candidate label set (a.k.a. complementary labels), which accurately indicates a set of labels that do not belong to a sample. In this paper, we use the non-candidate labels to induce a complementary classifier, which naturally forms an adversarial relationship against the traditional PLL classifier, to eliminate the false-positive labels in the candidate label set. Besides, we assume the feature space and the label space share the same local topological structure captured by a dynamic graph, and use it to assist disambiguation. Extensive experimental results validate the superiority of the proposed approach against state-of-the-art PLL methods on 4 controlled UCI data sets and 6 real-world data sets, and reveal the usefulness of complementary learning in PLL.

DALLA PERSONA AL SUBPERSONALE E RITORNO

description: The paper aims at elaborating a concept of a person in the light of recent developments in philosophy of mind and psychology, moving from an awareness of the current misfortune of this concept. Firstly, the distinction between personal and subpersonal levels of escription and explanation is examined, also in connection with the discoveries concerning the so-called ‘cognitive unconscious’. Then, the thesis according to which the personal level of explanation is not trustworthy at all (or may be reduced to subpersonal levels) is refuted and the need for an interaction between the two levels defended. This conclusion, however, leaves us with the problem of interfacing the two levels. I argue that a necessary premise for dealing successfully with this ‘interface problem’ is to restate a conception of ourselves as persons, while ‘person’ is conceived as a sortal concept. Thus ‘person’ is to be considered not a concept belonging to the personal level of analysis, but the concept of a basic particular to which both personal-level and sub-personal level properties can be attributed. For this very reason, a person is also the real and logical space of possibility and intelligibility of the phenomena belonging to the personal level, as well as of those belonging to the sub-personal levels, namely their coexistence, conflict, integration, etc. It is also for this reason that the concept of a person is more useful and valuable today than those of ‘I’, ‘subject’, and so on. The proposal defended in this paper does not have a metaphysical character; nevertheless this way of conceiving persons (and personal identity) implies a break with the tradition opened by Locke: but this line of thought was, in any case, at a dead end.
