description: In 1998, early childhood teachers throughout Queensland were required to attend a professional development program to familiarise them with the new Preschool Curriculum Guidelines. While this 'top down' or mandated professional development activity was characteristic of the type of professional development usually accessed by early childhood teachers, it provided no guarantees that any changes to teaching or learning would be subsequently incorporated into early childhood classrooms. The professional development activity also demonstrated the continued use of the 'expert' model as a means of bringing about changes to teaching practices. This report explores the shortcomings of this 'expert' model. Using the outcomes from a teacher initiated professional development activity that used action research strategies as its' framework, the report demonstrates the explicit links between professional development and change, and highlights the advantages of using action research as a framework for effective professional development activities. The report concludes with a series of recommendations for future professional development activities in the field of early childhood.

description: One major objective of controlling classical chaotic dynamical systems is exploiting the system’s extreme sensitivity to initial conditions in order to arrive at a predetermined target state. In a recent Letter [Phys. Rev. Lett. 130, 020201 (2023)], a generalization of this targeting method to quantum systems was demonstrated using successive unitary transformations that counter the natural spreading of a quantum state. In this paper further details are given and an important quite general extension is established. In particular, an alternate approach to constructing the coherent control dynamics is given, which introduces a time-dependent, locally stable control Hamiltonian that continues to use the chaotic heteroclinic orbits previously introduced, but without the need of countering quantum state spreading. Implementing that extension for the quantum kicked rotor generates a much simpler approximate control technique than discussed in the Letter, which is a little less accurate, but far more easily realizable in experiments. The simpler method’s error can still be made to vanish as ℏ→0.

description: ZnO-ZnWO4 is a self-organised eutectic composite consisting of parallel ZnO thin layers (lamellae) embedded in a dielectric ZnWO4 matrix. Electromagnetic behavior of composite materials is affected not only by the properties of single constituent materials, but also by their reciprocal geometrical micro-/nano-structurization, as in the case of ZnO-ZnWO4. The light interacting with microscopic structural features in the composite material provides new optical properties, which overcome the possibilities offered by the constituent materials. Here we show remarkable active and passive polarization control of this composite over various wavelength ranges; these properties are based on the crystal orientation of ZnO with respect to biaxiality of ZnWO4 matrix. In the visible range, polarization dependent polarized luminescence occurs for blue light emitted by ZnO. Moreover, we report on the enhancement of second harmonic generation of the composite with respect to its constituents, due to the phase matching condition. Finally, in the medium infrared spectral region (MIR), the composite behaves as a metamaterial with strong polarization dependence.

description: Project Tittle: Test-Retest Reliability of a Physical Activity Behavior, Health and Wellbeing Questionnaire in Adolescents
The data was collected as part of a test-retest reliability study on a physical activity behavior, health and wellbeing questionnaire in adolescents and was conducted via the Physical Education and Sport Sciences Department and Health Research Institute in the University of Limerick. Research ethics approval for this study and the associated protocols was granted by the research ethics committee of the Faculty of Education and Health Sciences, University of Limerick. The study aimed to examine the test-retest reliability of the physical activity behavior, health and wellbeing questionnaire in adolescent populations, administered by teachers in school settings, in the Republic of Ireland. A cross-sectional included 55 participants (45.5% males: Age,13.94 (±.40) were included. The participants completed the questionnaire on two occasions (T1 and T2), on the same day and time, one week apart following identical proceduresThe physical activity behaviour, health and wellbeing survey was assembled using tools with previously established validity. Although some research exists to support the reliability of questionnaires to measure physical activity behavior, health and wellbeing, there is a scarcity of research examining the reliability of tools to estimate all components as part of one questionnaire, utilizing a range of relative and absolute reliability indices.The questionnaire consists of variety of physical activity behaviour (n=13), health (n=11) and wellbeing (n=2) variables. The data was collected between January and March 2023. The current survey is supporting information for publication.
Intrinsic Brightness Temperatures of Compact Radio Jets as a Function of Frequency

description: We present results of our investigation of the radio intrinsic brightness temperatures of compact radio jets. The intrinsic brightness temperatures of about 100 compact radio jets at 2, 5, 8, 15, and 86 GHz are estimated based on large VLBI surveys conducted in 2001-2003 (or in 1996 for the 5 GHz sample). The multi-frequency intrinsic brightness temperatures of the sample of jets are determined by a statistical method relating the observed brightness temperatures with the maximal apparent jet speeds, assuming one representative intrinsic brightness temperature for a sample of jets at each observing frequency. By investigating the observed brightness temperatures at 15 GHz in multiple epochs, we found that the determination of the intrinsic brightness temperature for our sample is affected by the flux density variability of individual jets at time scales of a few years. This implies that it is important to use contemporaneous VLBI observations for the multi-frequency analysis of intrinsic brightness temperatures. Since our analysis is based on the VLBI observations conducted in 2001-2003, the results are not strongly affected by the flux density variability. We found that the intrinsic brightness temperature $T_{\rm 0}$ increases as $T_{\rm 0}\proptoν_{\rm obs}^ξ$ with $ξ=0.7$ below a critical frequency $ν_{\rm c}\approx9 {\rm GHz}$ where energy losses begin to dominate the emission. Above $ν_{\rm c}$, $T_{\rm 0}$ decreases with $ξ=-1.2$, supporting for the decelerating jet model or particle cascade model. We also found that the peak value of $T_{\rm 0}\approx3.4\times10^{10}$ K is close to the equipartition temperature, implying that the VLBI cores observable at 2-86 GHz may be representing jet regions where the magnetic field energy dominates the total energy in jets.

description: We present an ab initio calculation of the shear viscosity as a function of interaction strength in a two-component unpolarized Fermi gas near the unitary limit, within a finite temperature quantum Monte Carlo (QMC) framework and using the Kubo linear-response formalism. The shear viscosity decreases as we tune the interaction strength 1/ak_F from the Bardeen-Cooper-Schrieffer side of the Feshbach resonance towards Bose-Einstein condensation limit and it acquires the smallest value for 1/ak_F approx 0.4, with a minimum value of (eta/s)_min approx 0.2 hbar/k_B, which is about twice as small as the value reported for experiments in quark-gluon plasma (eta/s)_QGP lesssim 0.4 hbar/k_B. The Fermi gas near unitarity thus emerges as the most "perfect fluid" observed so far in nature. The clouds of dilute Fermi gas near unitarity exhibit the unusual attribute that, for the sizes realized so far in the laboratory or larger (less than 10^9 atoms), can sustain quantum turbulence below the critical temperature, but at the same time the classical turbulence is suppressed in the normal phase.

description: The continuum mechanics of line defects representing singularities due to terminating discontinuities of the elastic displacement and its gradient field is developed. The development is intended for application to coupled phase transformation, grain boundary, and plasticity-related phenomena at the level of individual line defects and domain walls. The continuously distributed defect approach is developed as a generalization of the discrete, isolated defect case. Constitutive guidance for equilibrium response and dissipative driving forces respecting frame-indifference and non-negative mechanical dissipation is derived. A differential geometric interpretation of the defect kinematics is developed, and the relative simplicity of the actual adopted kinematics is pointed out. The kinematic structure of the theory strongly points to the incompatibility of dissipation with strict deformation compatibility.

description: A forced degradation study on novel glaucoma drug netarsudil was performed as per ICH and WHO guidelines. All the degradation products were separated from the drug on a C-18 column utilizing ammonium acetate buffer (10 mM, pH 4.90) as a mobile phase-A and acetonitrile: methanol (70:30) v/v as mobile phase-B, by employing gradient elution mode. The injection volume was 10 µL with a 0.8 mL/min flow rate. The detection wavelength was 245 nm and the study was executed at a constant column temperature of 40 °C. Initially, the mass fragmentation pathway of the drug was postulated followed by characterization of degradation products from LC-MS-TOF/MS data. This was followed by LC-MS/TOF studies on the degradation products. Significant degradation was witnessed in alkaline and acidic conditions whereas no signification decline in the drug was observed in other decomposition environments. A total of four degradation products were formed and characterized with the aid of high-resolution mass spectrometry. The mechanistic pathway of formation of all DPs from netarsudil is established. In addition, comparative toxicity properties of the drug and degradation products were established using the online web server Pro Tox II.

description: The generation and distribution of electricity comprises nearly 40% of U.S. CO(2), emissions, as well as large shares of SO(2), NO(x), small particulates, and other toxins. Thus, correctly accounting for these electricity-related environmental releases is of great importance in life cycle assessment of products and processes. Unfortunately, there is no agreed-upon protocol for accounting for the environmental emissions associated with electricity, as well as significant uncertainty in the estimates. Here, we explore the limits of current knowledge about grid electricity in LCA and carbon footprinting for the U.S. electrical grid, and show that differences in standards, protocols, and reporting organizations can lead to important differences in estimates of CO(2) SO(2), and NO(x) emissions factors. We find a considerable divergence in published values for grid emissions factor in the U.S. We discuss the implications of this divergence and list recommendations for a standardized approach to accounting for air pollution emissions in life cycle assessment and policy analyses in a world with incomplete and uncertain information.

description: This thesis explores the relationship between surface and depth in photography and their influence on identity formation from the perspective of an Asperger’s personality. I saw in my prior work a sense of duality, a conceptual in-between space and the need to construct photographs as a metaphor for my confused sense of self. The present work is an exploration of how my perspective on identity expresses itself in my photographic work, which I have contextualized in relation to the apparent dialectic of internal/individual (being) versus external/social (constructedness). I have further contextualized my work relative to four artists I have identified as representing the use of portrait photography as a means of exploring what lies beneath the surface: Guillaume‐Benjamin‐Amand Duchenne de Boulogne’s direct, literal approach, Florence Henri’s connection between literal and metaphorical, Nancy Burson’s consideration of the relationship between “believing” and “seeing”, and Elisabeth King’s exploration of the relationship between mind and body through “attention’s loop”. My projects, “emotional me”, “mirror/mask”, “collaborative self‐portrait”, and “the emotions project” individually and collectively play on key elements of each of these four approaches to identity. There is a way to balance between internal needs and external pressures when forming a sense of self. For me that balance is found not in words but in a non‐linguistic, non‐linear form of photographic narrative. I have come to believe that photography – which I see as a medium that both transmits and reflects, that retains some of the pre‐modern assumption of transparency – is the medium that will allow me to explore the incomprehensible.

description: Speculative multi-threading (SpMT) has been proposed as a perspective method to exploit Chip Multiprocessors (CMP) hardware potential. It is a thread level speculation (TLS) model mainly depending on software and hardware co-design. This paper researches speculative thread-level parallelism of general purpose programs and a speculative multi-threading execution model called Prophet is presented. The architectural support for Prophet execution model is designed based on CMP. In Prophet the inter-thread data dependency are predicted by pre-computation slice (p-slice) to reduce RAW violation. Prophet multi-versioning Cache system along with thread state control mechanism in architectural support are utilized for buffering the speculative data, and a snooping bus based cache coherence protocol is used to detect data dependence violation. The simulation-based evaluation shows that the Prophet system could achieve significant speedup for general-purpose programs.

description: This paper introduces a damage diagnosis algorithm for civil structures that uses a sequential change point detection method. The general change point detection method uses the known pre- and post-damage feature distributions to perform a sequential hypothesis test. In practice, however, the post-damage distribution is unlikely to be known a priori, unless we are looking for a known specific type of damage. Therefore, we introduce an additional algorithm that estimates and updates this distribution as data are collected using the maximum likelihood and the Bayesian methods. We also applied an approximate method to reduce the computation load and memory requirement associated with the estimation. The algorithm is validated using a set of experimental data collected from a four-story steel special moment-resisting frame and multiple sets of simulated data. Various features of different dimensions have been explored, and the algorithm was able to identify damage, particularly when it uses multidimensional damage sensitive features and lower false alarm rates, with a known post-damage feature distribution. For unknown feature distribution cases, the post-damage distribution was consistently estimated and the detection delays were only a few time steps longer than the delays from the general method that assumes we know the post-damage feature distribution. We confirmed that the Bayesian method is particularly efficient in declaring damage with minimal memory requirement, but the maximum likelihood method provides an insightful heuristic approach.

description: Abstract: "This paper presents a systematic procedure for the retrofit design of heat exchanger networks. The approach is divided into a prescreening stage and an optimization stage. In the prescreening stage, the economic feasibility of the project is analyzed with lower bounds on cost for utility, additional area, and structural modifications. The bounds are used to construct a prescreening cost plot which shows the best possible savings that can be derived from a retrofit project. In the optimization stage, information from the prescreening stage is used to construct a novel superstructure which has embedded alternative retrofit designs for reassigning existing exchangers to different streams, introducing new exchangers to the network, and adding piping and area modifications.The superstructure is optimized with a mixed integer nonlinear programming (MINLP) formulation to determine the retrofit network requiring least total annual cost. Heat loads, minimum approach temperature (EMAT), and hot stream/cold stream matches are not fixed but are optimized in order to accurately account for the tradeoffs between capital and energy cost. Several examples are presented to illustrate this method."
Analytical solutions for the flow of Carreau and Cross fluids in circular pipes and thin slits

description: In this paper, analytical expressions correlating the volumetric flow rate to the pressure drop are derived for the flow of Carreau and Cross fluids through straight rigid circular uniform pipes and long thin slits. The derivation is based on the application of Weissenberg-Rabinowitsch-Mooney-Schofield method to obtain flow solutions for generalized Newtonian fluids through pipes and our adaptation of this method to the flow through slits. The derived expressions are validated by comparing their solutions to the solutions obtained from direct numerical integration. They are also validated by comparison to the solutions obtained from the variational method which we proposed previously. In all the investigated cases, the three methods agree very well. The agreement with the variational method also lends more support to this method and to the variational principle which the method is based upon.

description: Even though offline evaluation is just an imperfect proxy of online performance -- due to the interactive nature of recommenders -- it will probably remain the primary way of evaluation in recommender systems research for the foreseeable future, since the proprietary nature of production recommenders prevents independent validation of A/B test setups and verification of online results. Therefore, it is imperative that offline evaluation setups are as realistic and as flawless as they can be. Unfortunately, evaluation flaws are quite common in recommender systems research nowadays, due to later works copying flawed evaluation setups from their predecessors without questioning their validity. In the hope of improving the quality of offline evaluation of recommender systems, we discuss four of these widespread flaws and why researchers should avoid them.

description: We demonstrate theory and computations for finite-energy line defect solutions in an improvement of Ericksen-Leslie liquid crystal theory. Planar director fields are considered in two and three space dimensions, and we demonstrate straight as well as loop disclination solutions. The possibility of static balance of forces in the presence of a disclination and in the absence of flow and body forces is discussed. The work exploits an implicit conceptual connection between the Weingarten-Volterra characterization of possible jumps in certain potential fields and the Stokes-Helmholtz resolution of vector fields. The theoretical basis of our work is compared and contrasted with the theory of Volterra disclinations in elasticity. Physical reasoning precluding a gauge-invariant structure for the model is also presented

description: In type-II superconductors, the dynamics of superconducting vortices determine their transport properties. In the Ginzburg-Landau theory, vortices correspond to topological defects in the complex order parameter. Extracting their precise positions and motion from discretized numerical simulation data is an important, but challenging task. In the past, vortices have mostly been detected by analyzing the magnitude of the complex scalar field representing the order parameter and visualized by corresponding contour plots and isosurfaces. However, these methods, primarily used for small-scale simulations, blur the fine details of the vortices, scale poorly to large-scale simulations, and do not easily enable isolating and tracking individual vortices. Here we present a method for exactly finding the vortex core lines from a complex order parameter field. With this method, vortices can be easily described at a resolution even finer than the mesh itself. The precise determination of the vortex cores allows the interplay of the vortices inside a model superconductor to be visualized in higher resolution than has previously been possible. By representing the field as the set of vortices, this method also massively reduces the data footprint of the simulations and provides the data structures for further analysis and feature tracking.

The phenomenon of questioning as perceived by visual arts students: A case study

description: The process of questioning and its relationship to researching, problem solving and experimentation are central to visual arts education policy in Queensland, Australia. The aim of the study was to consider diverse forms of questioning within the context of quality education. This study focuses on the notion that questioning is a cyclic process as opposed to a singular action. The issues related to questioning that are discussed by this study were primarily generated by the students during the course of the practicum. How questioning is perceived by the student is therefore of specific interest to this study. Using as a framework the concept that questioning is an all encompassing concept which may be investigative rather than outcome based, a qualitative rather than quantitative approach has been used to achieve the objectives of the study. The research presented here is a critical interpretation based upon case study information with a participant- researcher focus. The case study focuses on secondary school students who have some connection with Asian cultures, and are being educated within the context of the Australian classroom. Significantly the constant review of Australia's position and identity within the Asia -Pacific region has major social and cultural implications for teachers and students in Australian classrooms as reflection upon others and self is considered to be both educationally enriching and necessary. This study proposes that some of the issues related to questioning for Taiwanese and other Asian students may reveal useful information that in various forms becomes relevant to all students. The subsequent outcomes may, over a period of time, contribute to reviewed pedagogy and a renewed interest in the phenomenology of questioning.
Joint inverse cascade of magnetic energy and magnetic helicity in MHD turbulence

description: We show that oppositely directed fluxes of energy and magnetic helicity coexist in the inertial range in fully developed magnetohydrodynamic (MHD) turbulence with small-scale sources of magnetic helicity. Using a helical shell model of MHD turbulence, we study the high Reynolds number magnetohydrodynamic turbulence for helicity injection at a scale that is much smaller than the scale of energy injection. In a short range of scales larger than the forcing scale of magnetic helicity, a bottleneck-like effect appears, which results in a local reduction of the spectral slope. The slope changes in a domain with a high level of relative magnetic helicity, which determines that part of the magnetic energy related to the helical modes at a given scale. If the relative helicity approaches unity, the spectral slope tends to $-3/2$. We show that this energy pileup is caused by an inverse cascade of magnetic energy associated with the magnetic helicity. This negative energy flux is the contribution of the pure magnetic-to-magnetic energy transfer, which vanishes in the non-helical limit. In the context of astrophysical dynamos, our results indicate that a large-scale dynamo can be affected by the magnetic helicity generated at small scales. The kinetic helicity, in particular, is not involved in the process at all. An interesting finding is that an inverse cascade of magnetic energy can be provided by a small-scale source of magnetic helicity fluctuations without a mean injection of magnetic helicity.

description: This is the artifact accompanying the paper "PerSeVerE: Persistency Semantics for Verification under Ext4" which is conditionally accepted in POPL'21.
 We consider our paper's artifact to be the set of benchmarks we used in the paper, as well as the results we got by running a particular version of Persevere (and its naive counterparts) on the benchmarks set. We do not consider the artifact of the paper to be Persevere itself, as it will evolve over time, and the results obtained by running the same benchmarks may differ in the future. We have made Persevere publicly available on \href{https://github.com/MPI-SWS/genmc}{GitHub}, as part of the GenMC tool. For any bugs, comments, or feedback regarding Persevere, please do not hesitate to contact us.

description: This paper explores creative practice as a form of embodied, situated, and material research that generates the potential for change. It examines the work of philosophers Gilles Deleuze and Felix Guattari as well as contemporary feminist theorists Moira Gatens, Genevieve Lloyd and Rosi Braidotti. Their philosophical position on bodies, compositions and emergence counters the dystopian views of catastrophe and death that are so pervasive in posthumanist discourses. Holly Schmidt articulates an engagement with ethological practices that seek to deterritorialize the disciplinary boundaries of art and science. These practices take up the composition of bodies, their speed and slowness, and ability to affect and be affected. Ethology involves creative actions that recompose relations. In meeting that complexity, Schmidt suggests there is potential to recompose contemporary technoculture while developing new ways of making and being in the world that meet the complexity of global issues. Schmidt looks to the figuration of fungi as a form of expression for its rich potential to create other possible worlds. Being neither plant nor animal fungus has created much debate and confusion in the history of taxonomic classification. It is the many ways in which fungi evade the logic of Western classification and organization that suggests it is a figuration worth exploring. Fungi are explored through Schmidt’s creative engagement with a variety of communities. Schmidt’s work varies, as does her medium of expression, which includes the spatial practice of walking, with the relational practices of coordinating social events, and the architecturally influenced practices of building forms for interaction.

Multi-Material Coatings with Reduced Thermal Noise

description: The most sensitive measurements of time and space are made with resonant optical cavities, and these measurements are limited by coating thermal noise. The mechanical and optical performance requirements placed on coating materials, especially for interferometric gravitational wave detectors, have proven extremely difficult to meet despite a lengthy search. In this paper we propose a new approach to high performance coatings; the use of multiple materials at different depths in the coating. To support this we generalize previous work on thermal noise in two-material coatings to an arbitrary multi-material stack, and develop a means of estimating absorption in these multi- material coatings. This new approach will allow for a broadening of the search for high performance coating materials.

description: Fuel cell and hydrogen applications will be key to enable the transition towards decarbonization and achieving the EU's targets of zero net greenhouse gas emissions by 2050. In the next years, priority will be set on the expansion of suitable hydrogen electrolyzers, such as solid oxide electrolysis cells (SOECs). Compared to other types of electrolyzers, the SOEC has a moderate technology readiness level (TRL 5-7). In order to facilitate the market entry and at the same time recover valuable raw materials, recycling concepts have to be developed and implemented at an early stage.The task of reusing or recovering high-temperature electrolyzer components is being addressed and focusses on the reprocessing of ceramic components of End-of-Life SOECs. Recycling in a closed-loop is particularly desirable, while the process is designed to be as scalable as possible. The biggest challenge for SOC recycling arises from the fact that no standardized manufacturing process for hydrogen electrolysis stacks/cells is currently existing. As a result, several cell types are available, sometimes differing significantly in their structures, materials and materials shares used. The cell designs can be divided into metal-supported cells (MSCs), electrolyte-supported cells (ESCs), and fuel electrode-supported cells (FESCs). Even within one cell type, differences can occur depending on the manufacturer. Therefore, it is likely that a classification and separation according to comparable cell types will be needed in the future.We focus mainly on the recycling of FESC-type cells. After separation from the stack, the cell will undergo different stages within the recycling process, illustrated in Figure 1. After re-oxidizing the whole cell, the air electrode and contact layer (~15 wt%) are removed by acid treatment, however most parts of the cell remain stable (~85 wt%). This solid fraction is further milled down and reprocessed to substrate slurry. Defined portions of the recycled slurry are admixed with standard slurry. The resulting green tapes and sintered bodies are investigated in terms of microstructure and mechanical stability.Parts of the liquid fraction of the cell, according to ~15 wt% of the cell, are recovered by oxalate precipitation of lanthanum. It was possible to recover ~95% of the lanthanum contained, which corresponds to about 60 wt% of the total dissolved load.

description: Reproducibility of recommender systems research has come under scrutiny during recent years. Along with works focusing on repeating experiments with certain algorithms, the research community has also started discussing various aspects of evaluation and how these affect reproducibility. We add a novel angle to this discussion by examining how unofficial third-party implementations could benefit or hinder reproducibility. Besides giving a general overview, we thoroughly examine six third-party implementations of a popular recommender algorithm and compare them to the official version on five public datasets. In the light of our alarming findings we aim to draw the attention of the research community to this neglected aspect of reproducibility.

description: We assess the economic value of life-cycle air emissions and oil consumption from conventional vehicles, hybrid-electric vehicles (HEVs), plug-in hybrid-electric vehicles (PHEVs), and battery electric vehicles in the US. We find that plug-in vehicles may reduce or increase externality costs relative to grid-independent HEVs, depending largely on greenhouse gas and SO(2) emissions produced during vehicle charging and battery manufacturing. However, even if future marginal damages from emissions of battery and electricity production drop dramatically, the damage reduction potential of plug-in vehicles remains small compared to ownership cost. As such, to offer a socially efficient approach to emissions and oil consumption reduction, lifetime cost of plug-in vehicles must be competitive with HEVs. Current subsidies intended to encourage sales of plug-in vehicles with large capacity battery packs exceed our externality estimates considerably, and taxes that optimally correct for externality damages would not close the gap in ownership cost. In contrast, HEVs and PHEVs with small battery packs reduce externality damages at low (or no) additional cost over their lifetime. Although large battery packs allow vehicles to travel longer distances using electricity instead of gasoline, large packs are more expensive, heavier, and more emissions intensive to produce, with lower utilization factors, greater charging infrastructure requirements, and life-cycle implications that are more sensitive to uncertain, time-sensitive, and location-specific factors. To reduce air emission and oil dependency impacts from passenger vehicles, strategies to promote adoption of HEVs and PHEVs with small battery packs offer more social benefits per dollar spent.
