description: While pyrochlore iridate thin films are theoretically predicted to possess a variety of emergent topological properties, experimental verification of these predictions can be obstructed by the challenge in thin film growth. Here we report on the pulsed laser deposition and characterization of thin films of a representative pyrochlore compound Bi2Ir2O7. The films were epitaxially grown on yttria-stabilized zirconia substrates and have lattice constants that are a few percent larger than that of the bulk single crystals. The film composition shows a strong dependence on the oxygen partial pressure. Density-functional-theory calculations indicate the existence of Bi_Ir antisite defects, qualitatively consistent with the high Bi: Ir ratio found in the films. Both Ir and Bi have oxidation states that are lower than their nominal values, suggesting the existence of oxygen deficiency. The iridate thin films show a variety of intriguing transport characteristics, including multiple charge carriers, logarithmic dependence of resistance on temperature, antilocalization corrections to conductance due to spin-orbit interactions, and linear positive magnetoresistance.

description: Annealing machines specialized for combinatorial optimization problems have been developed, and some companies offer services to use those machines. Such specialized machines can only handle binary variables, and their input format is the quadratic unconstrained binary optimization (QUBO) formulation. Therefore, discretization is necessary to solve problems with continuous variables. However, there is a severe constraint on the number of binary variables with such machines. Although the simple binary expansion in the previous research requires many binary variables, we need to reduce the number of such variables in the QUBO formulation due to the constraint. We propose a discretization method that involves using correlations of continuous variables. We numerically show that the proposed method reduces the number of necessary binary variables in the QUBO formulation without a significant loss in prediction accuracy.

The role of the food processing industry in the industrialisation strategy and development of Vietnam

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the Department of Economics and Finance, La Trobe Business School, College of Arts, Social Sciences and Commerce, La Trobe University, Bundoora.

This thesis is centred on an examination of the manufacturing sector in Vietnam against the backdrop of a reform and industrialisation process aimed at transforming the country’s export activities and wealth and strengthening integration into the world economy. Specific focus is placed on the potential contribution of the food processing industry in this regard, relative to traditional labour-intensive manufacturing industries, such as apparel, footwear and furniture, which have historically formed the backbone of employment and manufacturing activity in Vietnam. The thesis undertakes a detailed descriptive and analytical comparative analysis of the two industry categories using multiple sources of firm, industry and trade information, and examining indicators and variables including export share, comparative advantage, employment generation, output and value-added creation, and domestic input content. The thesis presents a compelling case supporting an important current and future role for the food processing industry in the development and transition of the Vietnam manufacturing sector, based on evidence of positive employment per enterprise growth, greater output generation and value added creation, more domestic input content, and a comparable share of total exports relative to the traditional labour-intensive industries. The analysis identifies the fish products industry as a particular leading light in terms of domestic input content, output generation and degree of comparative advantage, suggesting a significant potential contribution of this industry to the achievement of Vietnam’s industrial objectives. In total, these outcomes debunk the proposition that Vietnam should focus only on its labour abundance as its primary competitive advantage. Instead, they are more supportive of the food processing industry, and particularly the processing of fish and fish products, being a means for Vietnam to enhance the value chain of its manufacturing sector, embrace technology and intellectual capital and maximise the development and wealth creation within the Vietnam economy.

description: The frustrated pyrochlore iridate Pr$_2$Ir$_2$O$_7$ was proposed as a metallic quantum spin liquid located at a zero-field quantum critical point. Here we present the ultralow-temperature thermal conductivity measurements on the Pr$_2$Ir$_2$O$_7$ single crystals to detect possible exotic excitations. In zero field, the thermal conductivity shows a dramatic suppression above a characteristic temperature $T_s \approx$ 0.12 K. With increasing field, $T_s$ increases and the thermal conductivity tends to saturate above $H$ = 5 T. The Wiedemann-Franz law is verified at high fields and inferred at zero field. It suggests the normal behavior of electrons at the quantum critical point, and the absence of mobile fermionic magnetic excitations. The strong suppression of thermal conductivity is attributed to the scattering of phonons by the spin system, likely the fluctuating spins. These results shed new light on the microscopic description on this novel compound.

description: A light stop with mass almost degenerate with the lightest neutralino has important connections with both naturalness and dark matter relic abundance. This region is also very hard to probe at colliders. In this paper, we demonstrate the potential of searching for such stop particles at the LHC from sbottom decays, focusing on two channels with final states $2\ell+E^{\rm miss}_{\rm T}$ and $1b1\ell+E^{\rm miss}_{\rm T}$. We found that, if the lightest sbottom has mass around or below 1 TeV and has a significant branching ratio to decay to stop and $W$ ($\tilde{b} \to \tilde{t}\,W$), a stop almost degenerate with neutralino can be excluded up to about 500-600 GeV at the 13 TeV LHC with $300\,{\rm fb}^{-1}$ data. The searches we propose are complementary to other SUSY searches at the LHC and could have the best sensitivity to the stop-bino coannihilation region. Since they involve final states which have already been used in LHC searches, a reinterpretation of the search results already has sensitivity. Further optimization could deliver the full potential of these channels.

description: We study the eigenvalue problem for a one-dimensional Dirac operator with a spatially varying ``mass'' term. It is well-known that when the mass function has the form of a kink, or \emph{domain wall}, transitioning between strictly positive and strictly negative asymptotic mass, $\pmκ_\infty$, at $\pm\infty$, the Dirac operator has a simple eigenvalue of zero energy (geometric multiplicity equal to one) within a gap in the continuous spectrum, with corresponding \emph{zero mode}, an exponentially localized eigenfunction. We prove that when the mass function has the form of \emph{two} domain walls separated by a sufficiently large distance $2 δ$, the Dirac operator has two real simple eigenvalues of opposite sign and of order $e^{- 2 |κ_\infty| δ}$. The associated eigenfunctions are, up to $L^2$ error of order $e^{- 2 |κ_\infty| δ}$, linear combinations of shifted copies of the single domain wall zero mode. For the case of three domain walls, there are two non-zero simple eigenvalues as above and a simple eigenvalue at energy zero. Our methods are based on a Lyapunov-Schmidt reduction strategy and we outline their natural extension to the case of $n$ domain walls for which the minimal distance between domain walls is sufficiently large. The class of Dirac operators we consider controls the bifurcation of topologically protected ``edge states'' from Dirac points (linear band crossings) for classes of Schrödinger operators with domain-wall modulated periodic potentials in one and two space dimensions. The present results may be used to construct a rich class of defect modes in periodic structures modulated by multiple domain walls.

Efficient methods for one-shot quantum communication

Year: 2018
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We address the question of efficient implementation of quantum protocols, with small communication and entanglement, and short depth circuit for encoding or decoding. We introduce two new methods to achieve this, the first method involving two new versions of convex-split lemma that use small amount of additional resource (in comparison to prior version) and the second method being inspired by the technique of classical correlated sampling in computer science. These lead to a series of new consequences, as follows. First, we consider the task of quantum decoupling, where the aim is to apply an operation on a n-qubit register so as to make it independent of an inaccessible quantum system. Many previous works achieve decoupling with the aid of a random unitary. It is known that random unitaries can be replaced by random circuits of size O(n\log n) and depth poly(\log n), or unitary 2-designs based on Clifford circuits of similar size and depth. We show that given any choice of basis such as the computational basis, decoupling can be achieved by a unitary that takes basis vectors to basis vectors. Thus, the circuit acts in a `classical' manner and additionally uses O(n) catalytic qubits in maximally mixed quantum state. Our unitary performs addition and multiplication modulo a prime and hence achieves a circuit size of O(n\log n) and logarithmic depth. This shows that the circuit complexity of integer multiplication (modulo a prime) is lower bounded by the optimal circuit complexity of decoupling. Next, we construct a new one-shot entanglement-assisted protocol for quantum channel coding that achieves near-optimal communication through a given channel. The number of qubits of pre-shared entanglement is exponentially smaller than that in the previous protocol near-optimal in communication. We also achieve similar results for one-shot quantum state redistribution.

description: Cardiac motion estimation is an important diagnostic tool to detect heart diseases and it has been explored with modalities such as MRI and conventional ultrasound (US) sequences. US cardiac motion estimation still presents challenges because of the complex motion patterns and the presence of noise. In this work, we propose a novel approach to estimate the cardiac motion using ultrafast ultrasound data. -- Our solution is based on a variational formulation characterized by the L2-regularized class. The displacement is represented by a lattice of b-splines and we ensure robustness by applying a maximum likelihood type estimator. While this is an important part of our solution, the main highlight of this paper is to combine a low-rank data representation with topology preservation. Low-rank data representation (achieved by finding the k-dominant singular values of a Casorati Matrix arranged from the data sequence) speeds up the global solution and achieves noise reduction. On the other hand, topology preservation (achieved by monitoring the Jacobian determinant) allows to radically rule out distortions while carefully controlling the size of allowed expansions and contractions. Our variational approach is carried out on a realistic dataset as well as on a simulated one. We demonstrate how our proposed variational solution deals with complex deformations through careful numerical experiments. While maintaining the accuracy of the solution, the low-rank preprocessing is shown to speed up the convergence of the variational problem. Beyond cardiac motion estimation, our approach is promising for the analysis of other organs that experience motion.

Enzyme-linked immunosorbent assays (ELISAs) utilize immobilized capture antibodies at solid-phase interfaces with enzymatic reporter molecules for antigen detection. ELISAs are employed globally for the detection and quantification of economically, medically, environmentally and industrially important antigens. In this work, a chromium complex containing the hexahydroxychromium (III) anion ([Cr(OH)6] 3- ) was used as a post-production, wet chemical modification to treat commercially available microtitre plates, for improved antibody immobilization and subsequent use in ELISA. The chromium modified plates improve the density and orientation of the capture antibody by binding its Fc portion, resulting in increased signal intensity, lower antigen detection limits, and increased speed of ELISAs. Production of the metal complex via various routes was explored using high-throughput methodology. The metal complex modification was then exemplified using a range of microtitre plates and sandwich ELISA systems. A diethylene glycol dimethyl ether plasma polymer thin film (DGpp) was then developed as a coating for microtitre well plates that provided a substrate for chromium binding. The resultant film, DGpp+Cr, offered a further ELISA improvement over previous methods with the enhanced signal due to correct orientation of captured antibody rather than a higher density of antibody binding. Time-of-flight secondary-ion mass spectrometry (ToF-SIMS) methods and multivariate analysis techniques, principal component analysis (PCA) and artificial neural networks (ANNs), were developed to probe antibody orientation on solid surfaces. These were use to directly demonstrate improved antibody orientation on DGpp+Cr over DGpp alone. ToF-SIMS, PCA and ANN were also employed to investigate classification of an antibody from its proteolytic fragments immobilized on silicon substrates. These methods were utilized to investigate antibody denaturation at the interface after ultrahigh vacuum storage, resulting in a "denaturation ratio" that is substrate and primary-ion independent. This research will be instrumental in improving not only immunoassay capabilities, but also mass spectral and multivariate analysis techniques employed to investigate complex biological systems.

description: Integer-forcing (IF) precoding, also known as downlink IF, is a promising new approach for communication over multiple-input multiple-output (MIMO) broadcast channels. Inspired by the integer-forcing linear receiver for multiple-access channels, it generalizes linear precoding by inducing an effective channel matrix that is approximately integer, rather than approximately identity. Combined with lattice encoding and a pre-inversion of the channel matrix at the transmitter, the scheme has the potential to outperform any linear precoding scheme, despite enjoying similar low complexity. In this paper, a specific IF precoding scheme, called diagonally-scaled exact IF (DIF), is proposed and shown to achieve maximum spatial multiplexing gain. For the special case of two receivers, in the high SNR regime, an optimal choice of parameters is derived analytically, leading to an almost closed-form expression for the achievable sum rate. In particular, it is shown that the gap to the sum capacity is upper bounded by 0.27 bits for any channel realization. For general SNR, a regularized version of DIF (RDIF) is proposed. Numerical results for two receivers under Rayleigh fading show that RDIF can achieve performance superior to optimal linear precoding and very close to the sum capacity.

Which way to work? Factors influencing participation in the workforce: perspectives of people with upper limb amputations and limb deficiencies

description: Submission note: A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Clinical Science (Occupational Therapy) to the Department of Occupational Therapy, School of Allied Health, Faculty of Science, Health & Engineering, La Trobe University, Victoria.

Participation in paid work is an important aspect of daily life and a key life role for Australian adults. People with upper limb loss (ULL) resulting from amputation or limb deficiency may face particular challenges in initiating or maintaining their work activities and roles, however this has received limited attention in the amputee-related literature to date. This study aimed to (a) describe the demographic, limb loss and employment-related characteristics of people attending one Victorian Upper Limb Amputee Clinic and (b) to explore what people living with ULL perceive as the factors influencing their work participation. A mixed methods approach was employed within a grounded theory framework. Fifty-five adults with ULL responded to a questionnaire about work participation. A subset of 13 questionnaire respondents participated in in-depth interviews to further explore their work experiences. Analysis of survey findings revealed that the study sample had similar characteristics to other groups of people with ULL described in international amputee literature. The majority of those who were less than working age at the time of ULL experienced paid work in adulthood, and 62% of those who were of working age at the time of ULL returned to work. A journeying metaphor was used to describe the experience of initiating participation in work with ULL and a range of factors were identified that influenced an individual’s experience. These included the impact of ongoing physical and psychological issues, perceived negative employer attitude, appropriate matching between job demands and capacity, use of strategies to minimise difference in appearance, and the support available through peers and informal networks. These findings highlight the complexity faced by people with ULL when attempting to initiate participation in paid work. Findings have applicability for people with ULL and health and vocational professionals, as well as funders, policy developers and service planners.

We show that for an explicit $d_{\mathrm{crit}}\in(1/3,1/2)$, for densities $d\in(1/3,d_{\mathrm{crit}})$ and for $n$ large enough, the model produces \emph{infinite} $n$-periodic groups. As an application, we obtain, for every fixed large enough $n$, for every $p\in (1,\infty)$ an infinite $n$-periodic group with fixed points for all isometric actions on $L^p$-spaces. Our main contribution is to show that certain random triangular groups are uniformly acylindrically hyperbolic.

description: The large class of inflationary models known as $α$- and $ξ$-attractors gives identical cosmological predictions at tree level (at leading order in inverse power of the number of efolds). Working with the renormalization group improved action, we show that these predictions are robust under quantum corrections. This means that for all the models considered the inflationary parameters $(n_s,r)$ are (nearly) independent on the Renormalization Group flow. The result follows once the field dependence of the renormalization scale, fixed by demanding the leading log correction to vanish, satisfies a quite generic condition. In Higgs inflation (which is a particular $ξ$-attractor) this is indeed the case; in the more general attractor models this is still ensured by the renormalizability of the theory in the effective field theory sense.

description: We describe the effect of ramified morphisms on Harbourne constants of reduced effective divisors. With this goal, we introduce the pullback of a weighted cluster of infinitely near points under a dominant morphism between surfaces, and describe some of its basic properties. As an application, we describe configurations of curves with transversal intersections and $H$-index arbitarily close to $-25/7\simeq -3.571$, smaller than any previously known result.

description: Este proyecto parte de las narraciones de la población de estudio que permitió identificar los hechos y vivencias del pasado, que son recordados con emoción, y alegría, asimismo los eventos pasados que están afectando la salud mental y psicológica de los adultos mayores institucionalizados en el Hogar San Pedro Claver de Bayunca. Observamos, que los estados de ánimo de los/as adultos mayores están relacionados con cambios psico afectivos marcados por diversos factores, como: la Institucionalización en hogares geriátricos, la jubilación, la pérdida del status económico, el duelo por perdida de hijos esposo(a), hermanos, la consciencia sobre su muerte en esta etapa de la vida es mayor y se observa magnificada. Muchos de estos cambios provocan que la población se cuestione sobre su propia identidad y valía, así, requieren de importantes esfuerzos de adaptación, en particular si son víctimas de abandono o excluidos de su núcleo familiar. Es por ello que la terapia de reminiscencia fue un buen argumento para mejorar la autoestima y el reconocimiento de las etapas de la historia de vida de los/as adultos mayores en el Hogar San Pedro Claver.

A Modified Stern-Gerlach Experiment Using a Quantum Two-State Magnetic Field

description: The Stern-Gerlach experiment has played an important role in our understanding of quantum behavior. We propose and analyze a modified version of this experiment where the magnetic field of the detector is in a quantum superposition, which may be experimentally realized using a superconducting flux qubit. We show that if incident spin-$1/2$ particles couple with the two-state magnetic field, a discrete target distribution results that resembles the distribution in the classical Stern-Gerlach experiment. As an application of the general result, we compute the distribution for a square waveform of the incident fermion. This experimental setup allows us to establish: (1) the quantization of the intrinsic angular momentum of a spin-$1/2$ particle, and (2) a correlation between EPR pairs leading to nonlocality, without necessarily collapsing the particle's spin wavefunction.

description: Banana plants do not only give delicious fruit but it can also provide banana fiber. Production of natural fiber is expected to increase because their production mostly centered on environmental friendly process and renewable. As a result production of natural fiber to satisfy the needs could take advantage over the synthetic fiber production in this regard. This study aimed at production, characterization and optimization of further process ability and mechanical property performance improvement of mechanically extracted banana fiber. So the final outcome of the research is to produce high quality banana trunk fiber which can be used in different sectors. The fiber is extracted manually by mechanical process. This is because of the fiber extracted mechanically was found to be appropriate for yarn spinning and knitting, have better color and tensile properties as well as the process is time conserving. The fiber obtained was treated with 0.1M, 0.3M and 0.5M of NaOH for different treatment time duration of 30min, 45min and 60min at the temperature of 300c, 600c and 900c. The fiber is treated with different concentration of chemical such bleaching agent hydrogen peroxide(5%) and lubricants such as castor oil (10%), sodium silicate(10%), soap(10%) and acetic acid(10%). Three parameters of treatment which are temperature, time and concentration was investigated. The effect of each parameter on the mechanical properties of the fiber was studied carefully by keeping the two other constant during treatment. In this study the obtained fiber is standardized (conditioned) at 200c and relative humidity of 60% for 24hr according to the standard method before the tensile test for textile fiber to ensure environmental equilibrium moisture content. The linear density of the banana fiber is determined for treated and non-treated using ASTM-D-6612 by putting 200mm of or both treated and untreated banana fiber in linear density measuring device. The linear density of untreated banana fiber is found to be 9.00Ne while for treated bleached and lubricated banana fiber is found as 26.80Ne. Finally the fiber was tested for its strength and other properties using yarn testing machine TEXTECHNO STATIMAT ME+ BY using ASTM: D -3822-07(ISO2062-500). It is found that treated banana fiber at a temperature of 900c with 0.3M of NaOH for 60minute produced the best quality and superior property in terms of tensile properties such as elongation, maximum force, work to break tenacity and time to break.

description: We present a numerical method which accurately computes the discrete spectrum and associated bound states of Hamiltonians which model electronic "edge" states localized at boundaries of one and two-dimensional crystalline materials. The problem is non-trivial since arbitrarily large finite "hard" truncations of the Hamiltonian in the infinite bulk direction tend to produce spurious bound states partially supported at the truncation. Our method, which overcomes this difficulty, is to compute the Green's function of the Hamiltonian by imposing an appropriate boundary condition in the bulk direction; then, the spectral data is recovered via Riesz projection. We demonstrate our method's effectiveness by studies of edge states at a graphene zig-zag edge in the presence of defects modeled both by a discrete tight-binding model and a continuum PDE model under finite difference discretization. Our method may also be used to study states localized at domain wall-type edges in one and two-dimensional materials where the edge Hamiltonian is infinite in both directions; we demonstrate this for the case of a tight-binding model of distinct honeycomb structures joined along a zig-zag edge.
