description: We investigate the energy spectrum of single layer black phosphorene nanoribbons (BPN) by means of a low-energy expansion of a recently proposed tight-binding model that describes electron and hole bands close to the Fermi energy level. Using the continuum approach, we propose boundary conditions based on sublattice symmetries for BPN with zigzag and armchair edges and show that our results for the energy spectra exhibit good agreement with those obtained by using the five-parameter tight-binding model. We also explore the behaviour of the energy gap versus the nanoribbon width $W$. Our findings demonstrate that band gap of armchair BPNs scale as $1/W^2$, while zigzag BPNs exhibit a $1/W$ tendency. We analyse the different possible combinations of the zigzag edges that result two-fold degenerate and non-degenerate edge states. Furthermore, we obtain expressions for the wave functions and discuss the limit of validity of such analytical model.

description: We develop a model that establishes a quantitative link between the physical properties of molecular aggregates and their constituent building blocks. The relation is built on the coherent potential approximation, calibrated against exact results, and proven reliable for a wide range of parameters. It provides a practical method to compute spectra and transfer rates in multi-chromophoric systems from experimentally accessible monomer data. Applications to Förster energy transfer reveal optimal transfer rates as functions of both the system-bath coupling and intra-aggregate coherence.

description: We present the experimental characterization of two distant double-slit masks illuminated by chaotic light, in the absence of first-order imaging and interference. The scheme exploits second-order interference of light propagating through two indistinguishable pairs of {\it disjoint} optical paths passing through the masks of interest. The proposed technique leads to a deeper understanding of biphoton interference and coherence, and opens the way to the development of novel schemes for retrieving information on the relative position and the spatial structure of distant objects, which is of interest in remote sensing, biomedical imaging, as well as monitoring of laser ablation, when first-order imaging and interference are not feasible.

Challenges and Prospects of Scaffolding: Humanization and Individualization of Education in the Context of Industry 5.0
Creators: name: Bobro, Natalia
Publisher: name: Zenodo
Year: 2024
Subjects: educational environment, digitalization, digitalization, educational process, education, pedagogical competencies

description: The article explores the current challenges of the modern educational process and the possibilities of using the subtechnology of scaffolding to overcome them. The main attention is paid to the humanization of education, which implies a reorientation of pedagogical activity from the social and applied sphere to the sphere of personal development. This requires the creation of an educational environment that stimulates the disclosure of the human essence of an individual in its entirety, not just as a social tool. The formalization of the gap between students and teachers, in particular in the context of digitalization, is another significant problem, as the digital divide changes the relationship between them. The problem of individualization of the personality in the context of the globalization of the educational process is studied. Individualization is carried out through self-development within the framework of self-education, self-study, and self-education, which allows a person to acquire specific knowledge, skills, and attitudes, overcoming socio-psychological forms of similarity. In the information society, this also includes information individualization as a mechanism for transferring and assimilating social experience. A significant decline in student motivation to learn is seen as a critical problem. Traditional teaching methods often do not meet the modern needs of students who are accustomed to fast and interactive information. Lack of practical application of knowledge, as well as changes in social values, cause a loss of interest in learning. Social networks and media create the illusion of quick success without significant effort, which also affects academic performance. The traditional approach to education does not take into account the individual needs of students and limits the opportunities to develop critical thinking, creativity, problem-solving, and teamwork skills. Scaffolding, which involves providing support to the student in the right amount and at the right time, can contribute to individualization and increase the efficiency of the educational process. The article emphasizes the potential of scaffolding in solving problems of interaction between student and teacher, optimizing the educational process, and providing an individualized approach. However, due to the limited number of studies, the full use of this subtechnology is still problematic. Further research may reveal the potential of scaffolding as a key way to integrate humanistic values into artificial intelligence technologies in education.

The acculturation and adaptation of refugee youth in Australia: the role of family and peer factors
Creators: name: Buchanan, Zachary
Publisher: name: La Trobe
Year: 2023

description: Submission note: A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of clinical psychology to the School of Psychology and Public Health, College of Science, Health and Engineering, La Trobe University, Bundoora.

Children and adolescents form half the 16 million refugees who have fled their home countries due to war, persecution, famine, and other natural and human-made disasters. They are among the world’s most vulnerable people and are at risk of poor mental health and disrupted developmental trajectories. In Australia, the number of refugees increased by almost 50% from 13,500 to 20,000 in the last 5 years. With increasing numbers of refugees moving to Australia every year, it is important to better understand how this group might successfully cope with this major life transition. To this end, using Berry’s framework of bidimensional acculturation, predictors of acculturation and sociocultural and psychological adaptation among refugee youth in Australia (N = 106) were examined in this cross-sectional study. Specifically, the current thesis sought to address the following three questions: 1) what acculturation strategies do refugee youth most commonly use?; 2) to what extent do peer, language and family factors influence refugee youths’ acculturation and adaptation outcomes?; and 3) should refugee youth be treated separately to their non-refugee immigrant peers in acculturative research? Data derived from questionnaires were analysed using a series of correlation, ANOVA and regression analyses. Results revealed 1) refugee youth primarily show patterns of integration and marginalisation acculturation strategies, 2) a significant interplay of peer, language and family factors, particularly that of peer support, perceived discrimination, language proficiency and parental positive reinforcement, on refugee youths’ acculturation and adaptation outcomes, 3) refugee youth report overall poorer adaptation compared to non-refugee immigrant youth, however these differences seem also due in part to ethnic group membership, and 4) refugee youths’ pathways to adaptation are more different than similar compared to non-refugee immigrant youth. Taken together, the results of this thesis may help to increase support workers’ awareness of how aspects of refugee youths’ cultural identity and peer and family environments could influence their adjustment to Australia. It is hoped that this in turn will help inform the structure and focus of prevention and intervention programs specific to refugee youth.
Near-Optimal Approximate Shortest Paths and Transshipment in Distributed and Streaming Models

description: We present a method for solving the transshipment problem - also known as uncapacitated minimum cost flow - up to a multiplicative error of $1 + \varepsilon$ in undirected graphs with non-negative edge weights using a tailored gradient descent algorithm. Using $\tilde{O}(\cdot)$ to hide polylogarithmic factors in $n$ (the number of nodes in the graph), our gradient descent algorithm takes $\tilde O(\varepsilon^{-2})$ iterations, and in each iteration it solves an instance of the transshipment problem up to a multiplicative error of $\operatorname{polylog} n$. In particular, this allows us to perform a single iteration by computing a solution on a sparse spanner of logarithmic stretch. Using a randomized rounding scheme, we can further extend the method to finding approximate solutions for the single-source shortest paths (SSSP) problem. As a consequence, we improve upon prior work by obtaining the following results: (1) Broadcast CONGEST model: $(1 + \varepsilon)$-approximate SSSP using $\tilde{O}((\sqrt{n} + D)\varepsilon^{-3})$ rounds, where $ D $ is the (hop) diameter of the network. (2) Broadcast congested clique model: $(1 + \varepsilon)$-approximate transshipment and SSSP using $\tilde{O}(\varepsilon^{-2})$ rounds. (3) Multipass streaming model: $(1 + \varepsilon)$-approximate transshipment and SSSP using $\tilde{O}(n)$ space and $\tilde{O}(\varepsilon^{-2})$ passes. The previously fastest SSSP algorithms for these models leverage sparse hop sets. We bypass the hop set construction; computing a spanner is sufficient with our method. The above bounds assume non-negative edge weights that are polynomially bounded in $n$; for general non-negative weights, running times scale with the logarithm of the maximum ratio between non-zero weights.

Criminal courts and mental illness:an analysis of the efficacy of the assessment and referral court list of the magistrates’ court of Victoria
Creators: name: Chesser, Brianna
Publisher: name: La Trobe
Year: 2023

description: Submission note: A dissertation submitted in fulfilment of the degree of Doctor of Philosophy (law) to the La Trobe law School, the college of arts, social sciences and commerce, La Trobe University, Bundoora.

The criminal law has traditionally had difficulty in dealing with mentally ill offenders. This dissertation examines the ways in which the criminal justice system has evolved to accommodate mental illness. M’Naghten and traditional sentencing mechanisms deal with mental illness as mitigating factors. However, mental health courts go one step further, actively seeking rehabilitative and therapeutic outcomes for participants. Mental health court programs have been steadily increasing in number since the early 1990s. There is, however, little Australian research into the efficacy or otherwise of such programs; claims as to their effectiveness have largely been based on a handful of impressionistic studies. The aim of the current inquiry was to determine the degree to which participation in the Assessment and Referral Court (ARC) List in the Magistrates’ Court of Victoria reduced re‐offending rates by providing a comparative analysis of pre, peri, and post program offending and the time taken to re‐offend. The results of a two‐year recidivism study suggest that successful completion of the ARC List reduces recidivism. Furthermore, ARC is also effective at reducing the severity of offending behaviour post program completion. Several factors that ought to inform the ongoing development of Mental Health Diversionary Courts in Australia are also examined.
Automatism and art practice

description: The research project is to develop an understanding of the use of automatism in the practice of art derived from an interrelationship between the material process of art and critical text. As these practices converge in their vocabularies of the psychic and the somatic, they formulate a discourse of interpretation. The critical textual inquiry has identified an expanded language of interpretation for automatism within the vocabularies of three particular areas of investigation in, I. Psychoanalysis, 2. Phenomenology and certain currents of thought in Existentialism, and in 3. The theory and criticism of art. I have laid down an account of the field of research and my reading of it through six constituent writers: Freud, Ehrenzweig, Merleau-Ponty, Breton, Bataille and Rosenberg, determined from the artist-practitioner's perspective to be central contributors to an understanding of automatism. Four key terms have recurred in the material which I have identified in the research process as phenomena of automatist art practice; trauma, repetition, excess and gesture. As thinking continues in a contextualisation of art and critical theory they have provided further links to the theoretical language of current psychoanalysis and criticism by writers including: Agamben, Barthes, Foster, Krauss, Lacan and Lyotard. The focus of the practical inquiry rests upon an exploration of the communion between the unconscious mind and the body in automatism, derived from a studio practice with emphasis on a modelling and casting process. It is developed through the four key terms used as bridges in a critical exchange between the material practice and textual theory including original automatic writing. The theorising function of the art practice has been to initiate the four phases of the process of automatism as phenomena to be re-theorised through the four key terms as they are exemplified by a reflexive studio practice of automatist methodology in action. The body of art presented for examination selects works in series completed from 1996 -2006, in the following materials: bronze, paint, plaster, laser print and wax.

description: In this study, we evaluated the performance of the flow cytometer-based Sysmex UF-5000 automated urine analyzer as a screening tool for ruling out urinary tract infections in elderly patients presenting at the emergency department. A total of 1119 unselected patient samples (including 544 samples from elderly patients) submitted for urine culture were included in this study. Samples were measured on UF-5000 and dipsticks and the results were compared with interpretation of culture results, which is the gold standard. We obtained a diagnostic sensitivity of 99% and specificity of 51% with a low rate of false negatives (0.2%) and a negative predictive value of 99% at 108 colony forming bacteria/L (CFB/L). A bacterial count ≥ 50x106/L or yeast like cells ≥ 25x106/L was used as the cutoff value. At this cutoff value, 30% of the urine cultures would have been redundant. This resulted in 35% false positive samples, mainly due to particle contamination or nongrowing bacteria. In comparison, at best, the dipsticks have a diagnostic sensitivity of 89%, a specificity of 52% and a negative predictive value of 92% at 108 CFB/L.

description: We reconsider the possibility that the tension in the $|V_{cb}|$ determinations from inclusive and exclusive $B$ decay modes is due to a new physics effect. We modify the Standard Model effective Hamiltonian for semileptonic $b \to c$ transitions including a tensor operator with a lepton flavour dependent coupling $ε_T^\ell$, and investigate separately the muon and electron modes. The interference term between SM and NP, proportional to the lepton mass, has different impact in the inclusive and exclusive $B$ modes to muon. Moreover, even when the lepton mass is small as for the electron, the NP effect is different in inclusive and exclusive $B$ channels. For both $μ$ and $e$ we find a region of $ε_T^{μ,\,e}$ where the constraints from $B^- \to D^{(*)0} \ell^- {\bar ν}_\ell$ and $B \to X_c \, \ell \, \bar ν_\ell$ are satisfied for the same $|V_{cb}|$.

description: This volume goes beyond its initial goal of transferring the findings of the research project on "Cohesion building of multiethnic societies in Europe in the 11th-21st c" into school practice. It is based on the concept of "reading like a historian" developed by Sam Wineburg at Stanford University. "Reading" includes not only traditional written sources, but also iconographic material, such as medieval miniatures, coats of arms, photographs, as well as family trees and maps. It provides easy-to-adapt ideas, questions and tools to move from superficial browsing to an in-depth critical analysis, taking into account the origin of the material, its historical context and confrontation with other documents and data.

On the Development of a Generic Multi-Sensor Fusion Framework for Robust Odometry Estimation

Year: 2014

description: In this work we review the design choices, the mathematical and software engineering techniques employed in the development of the ROAMFREE sensor fusion library, a general, open-source framework for pose tracking and sensor parameter self-calibration in mobile robotics. In ROAMFREE, a comprehensive logical sensor library allows to abstract from the actual sensor hardware and processing while preserving model accuracy thanks to a rich set of calibration parameters, such as biases, gains, distortion matrices and geometric placement dimensions. The modular formulation of the sensor fusion problem, which is based on state-of-the-art factor graph inference techniques, allows to handle arbitrary number of multi-rate sensors and to adapt to virtually any kind of mobile robot platform, such as Ackerman steering vehicles, quadrotor unmanned aerial vehicles, omni-directional mobile robots. Different solvers are available to target high-rate online pose tracking tasks and offline accurate trajectory smoothing and parameter calibration. The modularity, versatility and out-of-the-box functioning of the resulting framework came at the cost of an increased complexity of the software architecture, with respect to an ad-hoc implementation of a platform dependent sensor fusion algorithm, and required careful design of abstraction layers and decoupling interfaces between solvers, state variables representations and sensor error models. However, we review how a high level, clean, C++/Python API, as long as ROS interface nodes, hide the complexity of sensor fusion tasks to the end user, making ROAMFREE an ideal choice for new, and existing, mobile robot projects.

description: We explored glucometabolic and renal function after engraftment in all 159 consecutive patients with type 1 diabetes who received pancreas transplantation alone (PTA, n = 80) or simultaneous pancreas and kidney transplantation (SPK, n = 79) in Norway from 2012 until 2017. We report fasting levels of plasma glucose (FPG), C-peptide, eGFR and the homeostasis model assessment of insulin sensitivity (HOMA2(%S)) and beta-cell function (HOMA2(%B)) measured one to three times weekly during the first 8 and at 52 weeks after transplantation. One year after engraftment, in the PTA and SPK groups 52 and 64 were normoglycaemic without exogenous insulin, and two and zero patients were dead. Data at the 52-week visit were missing for 5 and 6 patients in the respective groups. During the first 8 weeks, FPG was lower, C-peptide and HOMA2(%S) were higher and eGFR was lower in the SPK group as compared with the PTA group (all p < .05). 30 out of 157 living patients needed insulin treatment 52 weeks after transplantation, 9/79 in the SPK group and 21/78 in the PTA group (p = .02). In conclusion, patients who underwent SPK showed lower insulin sensitivity, but higher insulin secretory capacity and lower mean blood glucose levels the first 8 weeks after transplantation. Also, a higher proportion of patients in the SPK group were insulin-free after 1 year, compared with the PTA group.

description: This paper sets out to assess the state of capital mobility in Nigeria through the inter-temporal solvency approach. It is an attempt to identify the extent to which actual current account movements have deviated from what is considered optimal for international competitiveness. From this, one can infer a balance between export and import flows and the need to adopt macroeconomic policies necessary to ensure a sustainable external position. The results indicate the existence of a long-run equilibrium relationship between imports (including net investment income and transfers) and exports. However, in terms of current account sustainability, the results indicate otherwise. The presence of a structural break in the relationship between imports and exports is observed.

description: We study ODE models of epidemic spreading with a preventive behavioral response that is triggered by awareness of the infection. Previous studies of such models have mostly focused on the impact of the response on the initial growth of an outbreak and the existence and location of endemic equilibria. Here we study the question whether this type of response is sufficient to prevent future flare-ups from low endemic levels if awareness is assumed to decay over time. In the ODE context, such flare-ups would translate into sustained oscillations with significant amplitudes. Our results show that such oscillations are ruled out in Susceptible-Aware-Infectious-Susceptible models with a single compartment of aware hosts, but can occur if we consider two distinct compartments of aware hosts who differ in their willingness to alert other susceptible hosts.

description: Observations of pulsars across the radio spectrum are revealing a dependence of the characteristic scattering time ($τ$) on frequency, which is more complex than the simple power law with a theoretically predicted power law index. In this paper we investigate these effects using simulated pulsar data at frequencies below 300 MHz. We investigate different scattering mechanisms, namely isotropic and anisotropic scattering, by thin screens along the line of sight, and the particular frequency dependent impact on pulsar profiles and scattering time scales of each. We also consider how the screen shape, location and offset along the line of sight lead to specific observable effects. We evaluate how well forward fitting techniques perform in determining $τ$. We investigate the systematic errors in $τ$ associated with the use of an incorrect fitting method and with the determination of an off-pulse baseline. Our simulations provide examples of average pulse profiles at various frequencies. Using these we compute spectra of $τ$ and mean flux for different scattering setups. We identify setups that lead to deviations from the simple theoretical picture. This work provides a framework for interpretation of upcoming low frequency data, both in terms of modelling the interstellar medium and understanding intrinsic emission properties of pulsars.

description: Mycobacterium tuberculosis's (Mtb) autarkic lifestyle within the host involves rewiring its transcriptional networks to combat host-induced stresses. With the help of RNA sequencing performed under various stress conditions, we identified that genes belonging to Mtb sulfur metabolism pathways are significantly upregulated during oxidative stress. Using an integrated approach of microbial genetics, transcriptomics, metabolomics, animal experiments, chemical inhibition, and rescue studies, we investigated the biological role of non-canonical L-cysteine synthases, CysM and CysK2. While transcriptome signatures of RvΔcysM and RvΔcysK2 appear similar under regular growth conditions, we observed unique transcriptional signatures when subjected to oxidative stress. We followed pool size and labelling (34S) of key downstream metabolites, viz. mycothiol and ergothioneine, to monitor L-cysteine biosynthesis and utilization. This revealed the significant role of distinct L-cysteine biosynthetic routes on redox stress and homeostasis. CysM and CysK2 independently facilitate Mtb survival by alleviating host-induced redox stress, suggesting they are not fully redundant during infection. With the help of genetic mutants and chemical inhibitors, we show that CysM and CysK2 serve as unique, attractive targets for adjunct therapy to combat mycobacterial infection.

description: A few studies have examined biomarkers in patients with myocardial infarction (MI) and peripheral artery disease (PAD), i.e. multisite artery disease (MSAD). The aim of the study was firstly, to associate biomarkers with the occurrence of PAD/MSAD and secondly, if those can, in addition to clinical characteristics, identify MI patients with MSAD.In two prospectively observational studies including unselected patients with recent MI, PAD was defined as an abnormal ankle–brachial index (ABI) score (<0.9 or >1.4). The proximity extension assay (PEA) technique was used, simultaneously analyzing 92 biomarkers with association to cardiovascular disease. Biomarkers were tested for univariate associations with PAD. Random forest was used to identify biomarkers with a higher association to PAD. The additional discriminatory accuracy of adding biomarkers to clinical characteristics was analyzed by the c-statistics. Nine biomarkers were identified as significantly associated with MSAD/PAD in the primary patient cohort, analyzed early after the MI. In the prediction analysis, six biomarkers were identified associated with PAD. Three of these; Tumor necrosis factor receptor (TNFR-1), Tumor necrosis factor receptor 2 (TNFR-2) and Growth Differentiation Factor 15 (GDF-15) improved c-statistics when added to clinical characteristics from 0.683 (95% CI 0.610–0.756) to 0.715 (95% CI 0.645–0.784) in the primary patient cohort with a similar result, 0.729 (95% CI 0.687–0.770) to 0.752 (95% CI 0.771–0.792) in the secondary patient cohort. Biomarkers associated with inflammatory pathways are associated with MSAD in MI patients. Three biomarkers of 92; TNFR-1, TNFR-2 and GDF-15, in this exploratory added information in the prediction of MSAD and emphasis the importance of further studies.

description: Squeezed-state interferometry plays an important role in quantum-enhanced optical phase estimation, as it allows the estimation precision to be improved up to the Heisenberg limit by using ideal photon-number-resolving detectors at the output ports. Here we show that for each individual $N$-photon component of the phase-matched coherent $\otimes$ squeezed vacuum input state, the classical Fisher information always saturates the quantum Fisher information. Moreover, the total Fisher information is the sum of the contributions from each individual $N$-photon components, where the largest $N$ is limited by the finite number resolution of available photon counters. Based on this observation, we provide an approximate analytical formula that quantifies the amount of lost information due to the finite photon number resolution, e.g., given the mean photon number $\bar{n}$ in the input state, over $96$ percent of the Heisenberg limit can be achieved with the number resolution larger than $5\bar{n}$.
description: A new analytical result of the Fisher information (Eq.(18), or more generally, Eq.(B9)) has been derived to quantify how much the phase information is kept (or lost) due to finite number resolution of the photon-counting detectors

description: Developing reusable software is hard; systematically developing high quality reusable software components is even harder. With reusability in mind, there is pressure to be as generic as possible. Separating computational components from application--dependent functionalities is a key principle for building reusable robotic systems. This work introduces an approach where coordinating logic can be transparently inserted into a reusable component, along with data transforms unanticipated by the component author. Firstly, it proposes the Port Monitor Object which extends a component port's functionality with monitoring and event generation using runtime scripting languages. Secondly, the Port Arbitrator and its application to robotics is presented which enhances a port's capability to arbitrate input data from multiple sources. Lastly, it represents some applications of these approaches to further improve the reusability and robustness of robotics system.

description: The increasing significance of lightweight construction concepts requires innovative and adapted production technologies and process chains for the manufacturing of complex parts made of typical lightweight materials. The feasibility and potential of such a process chain consisting of the steps Bending - Electromagnetic compression (EMC) Hydroforming is shown in the present paper on the basis of a demonstrator part similar to a structural component from the automotive industry. Here, special focus is put on the requirements on the production steps and the workpiece properties. Furthermore, the development and testing of EMC-equipment that is optimally adapted to the special forming task is described.

This study investigated teachers’ emergent practices as they attempt to provide twenty-first century learning experiences in open-plan learning environments. The broad challenges to the industrial era model of education are coupled with the compelling need to provide contemporary learning processes. The focus on constructivist, student-oriented, collaborative, and personalised learning that is ICT-rich further establishes altered conditions requiring a new set of skills for teachers. This study examines the question, “What are the sustainable or generative skill sets in teaching and learning within open plan learning environments?”. Drawing on a multi-theoretical framework, including structuration theory (Giddens, 1984), relational agency (A. Edwards, 2005, 2009) and affordance theory (Gibson, 1977), this study focused on the heightened agency of teachers and students as expressed through both educational developments in constructivist pedagogies and architectural principles of openness, flexibility, humanism and democracy (Boddington and Boys, 2011; McGregor, 2004c; Melhuish, 2011; Upitis, 2004). In a multiple case study approach over two years I examined three school sites with open-plan design in regional Victoria. Field data included interviews with teachers and principals as well as a group interview with students. Observations of teaching were also conducted across the sites. The fine grain examination of teacher practice provides an opportunity to establish emergent patterns ground in lived experiences of altered school settings. The study found that open plan settings functioned as complex and intensified environments affording a range of practices and system responses. School level responses to the affordances of the space have made collaboration, adaptability and team orientation necessary features of the ongoing practice. The study explores the enablers and constraints in these settings on existing and desirable teacher skills. Metaphors and language to describe teaching practice are also considered in light of the altered conditions. The sustainable or generative skills require an ongoing and reflexive relationship with the brute physical space and the curriculum overlays established at school level.

description: We calculate the large deviation functions characterizing the long-time fluctuations of the occupation of drifted Brownian motion and show that these functions have non-analytic points. This provides the first example of dynamical phase transition that appears in a simple, homogeneous Markov process without an additional low-noise, large-volume or hydrodynamic scaling limit.
