description: Gallium Nitride Enhancement-Mode High ElectronMobility Transistors (GaN HEMTs) help to achieve high power density converter circuits thanks to their superior efficiency, higher switching speed and small package size. However, increased switching speed results in a sharp increase in short circuit (SC) current under a shoot-through fault with respect to other type of devices. GaN HEMTs can withstand the SC current only for several hundred nanoseconds. Therefore, fast SC protection solutions are critical for protecting power circuits. In this paper, the voltage induced by high slew rate of SC current on the high frequency power loop inductance resulting from the printed circuit board (PCB) layout is sensed to implement an ultra-fast short-circuit protection technique. The proposed technique does not increase circuit parasitics and providesflexibility in layout design that makes it suitable for parallelconnected GaN HEMTs, which require symmetric layout design for equal current sharing. A multi-pulse test is conducted under 1.56 MHz switching frequency, 400 VDC bus voltage and 40 A load current by using parallel connected GaN HEMTs in a halfbridge configuration to verify the robustness and reliability of the proposed protection technique. Experimental results show that the proposed protection technique is able to detect SC fault within 40 ns and fault is completely cleared with a soft turn-off in 250 ns.

description: Gallium Nitride Enhancement-Mode High Electron Mobility Transistors (GaN HEMTs) help to achieve high power density converter circuits thanks to their superior efficiency, higher switching speed and small package size. However, increased switching speed results in a dramatic increase in short circuit (SC) current under a shoot-through fault. GaN HEMTs can withstand the SC current only for several hundred nanoseconds.Therefore, fast SC protection solutions are critical for protecting power circuits. In this paper, an ultra-fast short-circuit protection technique based on sensing the voltage induced by high slew rate of SC current on the parasitic inductance of printed circuit board (PCB) layout is proposed. In the proposed design, an industrial prototype for parallel connected GaN HEMTs in a half-bridge configuration is implemented. In order to inhibit any over-voltage breakdown risk, a soft turn-off mechanism is utilized upon SC detection which discharges the gate-source voltage slowly instead of a fast turn-off. Experimental results show that the proposed protection technique is able to detect SC fault within 40 ns and fault is completely cleared in 250 ns. In addition to SC results, performance results of normal switching operation are provided to show the proposed technique does not affect the switching performance of GaN HEMTs.

description: Introduction: Contrary to stereotypes, Aboriginal and Torres Strait Islander Australians are more likely to abstain from drinking than other Australians. We explored characteristics and experiences of Aboriginal and Torres Strait Islander Australians who do not drink alcohol. Method: We conducted a cross-sectional, representative survey of 775 Aboriginal and Torres Strait Islander Australians (16+ years) in remote and urban South Australia. We explore correlates of not drinking alcohol using multi-level logistic regression. We describe reasons for non-drinking and harms participants experienced in past 12 months from others' drinking. Results: Non-drinking participants were more likely to be older (OR 1.35 [95% CI 1.21, 1.50] per decade) and unemployed (OR 2.72 [95% CI 1.77, 4.20]). Participants who spoke Aboriginal Australian languages at home were three times more likely to be lifetime abstainers from drinking (OR 3.07 [95% CI 1.52, 6.21]). Common reasons for not drinking alcohol were health and family. Most did not report harms from others' alcohol consumption (79.6%, 76.9%, urban and remote respectively). Stress from others' alcohol consumption was the most reported harm by non-drinkers (14.5% and 23.1%, urban and remote, respectively). Discussion and Conclusions: Culture such as speaking Aboriginal Australian languages might have protective effects that promote abstaining but was rarely explicitly cited as a reason for not drinking. A greater understanding of local values held by people who do not drink alcohol could help inform health messaging and other interventions to reduce alcohol-related harms. Understanding local reasons for abstaining can help tailor health messaging to suit local contexts.

description: Data Mining refers to the process of digging into the data so that one can find out patterns and gain knowledge about the patterns. Data is everywhere and it is generated in a sheer volume every day, resulting in the need to mine the data effectively. Classification is one of the techniques of data mining in which one finds a model that elucidates and distinguishes data classes and concepts. In this thesis, comparison of the different data mining techniques used in classification was done in Iris, Heart Disease, Wine, Car Evaluation, Adult, and Breast Cancer Wisconsin (Diagnostic) data sets. These data sets were unique and possessed a combination of varying characteristics like missing values, uni-variate/multivariate, having different nature/number of attribute etc. The natures of the aforementioned data sets were explored before their unique qualities were uncovered. Different data mining techniques for classification namely Decision Trees, K-Nearest Neighbor, Naive Bayes, Support Vector Machine and Artificial Neural Network were applied to each of these data set. Several performance analysis metrics like accuracy, precision, recall, F1 score, confusion matrix and MCC were used to analyze the aforementioned data mining techniques and the runtime and space consumption was analyzed as well.

description: Experiments using laser cooled atoms and ions show real promise for practical applications in quantum- enhanced metrology, timing, navigation, and sensing as well as exotic roles in quantum computing, networking and simulation. The heart of many of these experiments has been translated to microfabricated platforms known as atom chips whose construction readily lend themselves to integration with larger systems and future mass production. To truly make the jump from laboratory demonstrations to practical, rugged devices, the complex surrounding infrastructure (including vacuum systems, optics, and lasers) also needs to be miniatur- ized and integrated. In this paper we explore the feasibility of applying this approach to the Magneto-Optical Trap; incorporating the vacuum system, atom source and optical geometry into a permanently sealed micro- litre system capable of maintaining $10^{-10}$ mbar for more than 1000 days of operation with passive pumping alone. We demonstrate such an engineering challenge is achievable using recent advances in semiconductor microfabrication techniques and materials

description: Over the past decade, rapid advances in web technologies, coupled with innovative models of spatial data collection and consumption, have generated a robust growth in geo-referenced information, resulting in spatial information overload. Increasing 'geographic intelligence' in traditional text-based information retrieval has become a prominent approach to respond to this issue and to fulfill users' spatial information needs. Numerous efforts in the Semantic Geospatial Web, Volunteered Geographic Information (VGI), and the Linking Open Data initiative have converged in a constellation of open knowledge bases, freely available online. In this article, we survey these open knowledge bases, focusing on their geospatial dimension. Particular attention is devoted to the crucial issue of the quality of geo-knowledge bases, as well as of crowdsourced data. A new knowledge base, the OpenStreetMap Semantic Network, is outlined as our contribution to this area. Research directions in information integration and Geographic Information Retrieval (GIR) are then reviewed, with a critical discussion of their current limitations and future prospects.

description: In this note, we investigate the behaviour of suprema for band-limited spherical random fields. We prove upper and lower bound for the expected values of these suprema, by means of metric entropy arguments and discrete approximations; we then exploit the Borell-TIS inequality to establish almost sure upper and lower bounds for their fluctuations. Band limited functions can be viewed as restrictions on the sphere of random polynomials with increasing degrees, and our results show that fluctuations scale as the square root of the logarithm of these degrees.

description: For a double quantum dot (DQD) system, here we propose alternative ultrafast manipulate approach: Lyapunov control method, to transfer the state from R to L on the picosecond scale, orders of magnitude faster and transfer probability higher than the previously measured electrically controlled charge- or spin-based quits. The control laws are composed of two-direction components, one is used to eliminate the dissipation in the system, another is used to transfer the state. The control theory's stability ensures the system can be transferred to the target state in high probability, and the coefficients in control laws leads very fast convergence. The role of eliminating the dissipation plays the suppression of decoherence effect. Numerical simulation results show that under the realistic implementation conditions, the transfer probability and fidelity can be increased up to 98.79% and 98.97%, respectively. This is the first result directly applicable to a DQD system's state transferring using the Lyapunov control method. We also give specific experimental realization scheme.

description: Legendre orthogonal moments have been widely used in the field of image analysis. Because their computation by a direct method is very time expensive, recent efforts have been devoted to the reduction of computational complexity. Nevertheless, the existing algorithms are mainly focused on binary images. We propose here a new fast method for computing the Legendre moments, which is not only suitable for binary images but also for grey levels. We first set up the recurrence formula of one-dimensional (1D) Legendre moments by using the recursive property of Legendre polynomials. As a result, the 1D Legendre moments of order p, Lp = Lp(0), can be expressed as a linear combination of Lp-1(1) and Lp-2(0). Based on this relationship, the 1D Legendre moments Lp(0) is thus obtained from the array of L1(a) and L0(a) where a is an integer number less than p. To further decrease the computation complexity, an algorithm, in which no multiplication is required, is used to compute these quantities. The method is then extended to the calculation of the two-dimensional Legendre moments Lpq. We show that the proposed method is more efficient than the direct method.

description: In this paper, we focus on model reduction of large-scale bilinear systems. The main contributions are threefold. First, we introduce a new framework for interpolatory model reduction of bilinear systems. In contrast to the existing methods where interpolation is forced on some of the leading subsystem transfer functions, the new framework shows how to enforce multipoint interpolation of the underlying Volterra series. Then, we show that the first-order conditions for optimal H2 model reduction of bilinear systems require multivariate Hermite interpolation in terms of the new Volterra series interpolation framework; and thus we extend the interpolation-based first-order necessary conditions for H2 optimality of LTI systems to the bilinear case. Finally, we show that multipoint interpolation on the truncated Volterra series representation of a bilinear system leads to an asymptotically optimal approach to H2 optimal model reduction, leading to an efficient model reduction algorithm. Several numerical examples illustrate the effectiveness of the proposed approach.

description: The possible application of the barocaloric effect to produce solid state refrigerators is a topic of interest in the field of applied physics. In this work, we present experimental data about the influence of external pressure on the magnetic properties of a manganite with phase separation. Using the Jahn Teller effect associated with the presence of the charge ordering we were able to follow the transition to the ferromagnetic state induced by pressure. We also demonstrated that external pressure can assist the ferromagnetic state, decreasing the magnetic field necessary to generate the magnetic transition.

description: We test 16 bibliometric indicators with respect to their validity at the level of the individual researcher by estimating their power to predict later successful researchers. We compare the indicators of a sample of astrophysics researchers who later co-authored highly cited papers before their first landmark paper with the distributions of these indicators over a random control group of young authors in astronomy and astrophysics. We find that field and citation-window normalisation substantially improves the predicting power of citation indicators. The two indicators of total influence based on citation numbers normalised with expected citation numbers are the only indicators which show differences between later stars and random authors significant on a 1% level. Indicators of paper output are not very useful to predict later stars. The famous $h$-index makes no difference at all between later stars and the random control group.

description: We construct numerical integrators for Hamiltonian problems that may advantageously replace the standard Verlet time-stepper within Hybrid Monte Carlo and related simulations. Past attempts have often aimed at boosting the order of accuracy of the integrator and/or reducing the size of its error constants; order and error constant are relevant concepts in the limit of vanishing step-length. We propose an alternative methodology based on the performance of the integrator when sampling from Gaussian distributions with not necessarily small step-lengths. We construct new splitting formulae that require two, three or four force evaluations per time-step. Limited, proof-of-concept numerical experiments suggest that the new integrators may provide an improvement on the efficiency of the standard Verlet method, especially in problems with high dimensionality.

description: Farm assurance systems provide an infrastructure (standards and certification services) to ensure food safety, animal welfare and environmentally responsible practices at farms. Yet, farm assurance systems face challenges that threaten their legitimacy and social licence to operate (SLO) - especially when public shows increased concerns about the social and environmental impact of farming. Drawing from the SLO literature, we explore the relationship between key SLO constructs (distributional fairness, procedural fairness and confidence in governance) and trust in farm assurance in two independent studies: a qualitative study with farmers and assurance providers (N=37) and a survey of general public (N=500). The results suggest that (from a perspective of farmers and assurance providers), gaps in accountability for impact of assurance, gaps in inclusiveness of farmers and inconsistencies in governance impact trust in farm assurance. Distributional fairness, procedural fairness, and confidence in governance have positive effects on consumers' trust in the farms' assurance system, however consumers' engagement with food systems has unique influence against the three constructs. Combined, the two studies serve as a platform for a conceptual model of trust building for farm assurance.

description: Metal/semiconductor interfaces govern the operation of semiconductor devices through the formation of charge injection barriers that can be controlled by tuning the metal work function. However, the controlling ability is typically limited to being static. We show that a dynamic nature can be imparted to the interfaces using electrode surface modification with a structurally disordered molecular monolayer. The barrier height at the interfaces is altered significantly in a reversible way by an external electric field. As a result, a dramatic change in the carrier transport properties through the interfaces is observed, such as a reversible polarity reversion of metal/organic-semiconductor/metal diodes.

description: We formulate a theory of low-temperature, stationary photoluminescence from a quantum-dot molecule composed of two spherical quantum dots whose electronic subsystems are resonantly coupled via the Coulomb interaction. We show that the coupling leads to the hybridization of the first excited states of the quantum dots, manifesting itself as a pair of photoluminescence peaks with intensities and spectral positions strongly dependent on the geometric, material, and relaxation parameters of the quantum-dot molecule. These parameters are explicitly contained in the analytical expression for the photoluminescence differential cross section derived in the paper. The developed theory and expression obtained are essential in interpreting and analyzing spectroscopic data on the secondary emission of coherently coupled quantum systems.

description: The behavior of the second-order Lagrangian structure functions on state-of-the-art numerical data both in two and three dimensions is studied. On the basis of a phenomenological connection between Eulerian space-fluctuations and the Lagrangian time-fluctuations, it is possible to rephrase the Kolmogorov $4/5$-law into a relation predicting the linear (in time) scaling for the second order Lagrangian structure function. When such a function is directly observed on current experimental or numerical data, it does not clearly display a scaling regime. A parameterization of the Lagrangian structure functions based on Batchelor model is introduced and tested on data for $3d$ turbulence, and for $2d$ turbulence in the inverse cascade regime. Such parameterization supports the idea, previously suggested, that both Eulerian and Lagrangian data are consistent with a linear scaling plus finite-Reynolds number effects affecting the small- and large-time scales. When large-time saturation effects are properly accounted for, compensated plots show a detectable plateau already at the available Reynolds number. Furthermore, this parameterization allows us to make quantitative predictions on the Reynolds number value for which Lagrangian structure functions are expected to display a scaling region. Finally, we show that this is also sufficient to predict the anomalous dependency of the normalized root mean squared acceleration as a function of the Reynolds number, without fitting parameters.
Why firms offer new-issue direct stock purchase plans

Publisher: name: American University
Year: 2023

description: We investigate why firms choose to issue new shares to fund their direct stock purchase plans (DSPPs). The evidence supports our hypothesis that such firms are high growth firms facing shortages of internal capital along with a high marginal cost of external capital. We also hypothesize that firms use new-issue DSPPs to raise equity in smaller installments before making full-scale seasoned equity offerings (SEOs). The majority of firms in our sample offer SEOs within five years after initiating new-issue DSPPs. The market appears to perceive new-issue DSPPs as small-scale SEOs given that the reaction to SEO announcements is significantly higher for these firms than for matching firms without DSPPs.

This emphasizes the necessity for multiple responding units to work collaboratively during the response phase, making the exercise both multi-agency and cross-border in its orientation.
This deliverable describes the results from the harmonisation opportunities identified in the WP4 that have been tested in the UC4. In particular, the UC4 demonstrated the integration of advanced technologies such as drones and body cameras within the VALKYRIES platform.
Based on feedback from the participants involved in the exercise, UC4 was considered highly successful, and the VALKYRIES solutions introduced were well-received. This success emphasizes the ability of project to effectively address cross-border emergency response scenarios and leverage advanced technologies to improve emergency response capabilities in maritime environments.

description: The pnictide superconductor SrPtAs has a hexagonal layered structure containing inversion symmetry. It is formed by stacking two inequivalent PtAs layers separated by Sr layers. The former have no local (in-plane) inversion symmetry and therefore a (layer-) staggered Rashba spin orbit coupling appears which splits the three Kramers degenerate bands into six quasi-2D bands. The symmetry of the superconducting state of SrPtAs is unknown. Three candidates, spin-singlet $A_{1g}$ and $E_g$ as well as triplet $A_{2u}$ states have been proposed. We predict the quasiparticle interference (QPI) spectrum for these gap functions in t-matrix Born approximation. We show that distinct differences in the pattern of characteristic QPI wave vectors appear. These results may be important to determine the gap symmetry of SrPtAs by STM-QPI method.

description: At computer modeling of process of training it is usually supposed that all elements of a training material are forgotten with an identical speed. But in practice that knowledge which are included in educational activity of the pupil are remembered much more strongly and forgotten more slowly then knowledge which he doesn't use. For the purpose of more exact research of didactic systems is offered the model of training, in which consider that in case increasing the number of applications of this element of a learning material: 1) duration of its use by the pupil decreases; 2) the coefficient of forgetting decreases. The computer model is considered, programs in the Pascal language are submitted, results of modeling are given and analyzed. Keywords: didactics, information and cybernetic approach, computer modeling of process of training.

Deep VISTA observations of the Magellanic Clouds
Creators: name: Cioni, Maria-Rosa Lucia
Publisher: name: Zenodo
Year: 2023

description: The central regions of galaxies challenge observers with a high density of stars, gas and dust. The Large Magellanic Cloud hosts a dense stellar bar whereas the Small Magellanic Cloud hosts a dense core which have eluded even the most sensitive large-scale wide-field surveys of individual stars from the ground and from space. I will present first results from new observations with the wide-field near-infrared instrument VIRCam obtained under high-quality sky conditions. The aims of this project are to resolve stars fainter than the red clump and quantify features associated with the star formation, kinematics and structure of the inner regions of the galaxies. Furthermore, to establish how mutual interactions and with the Milky Way have influenced the most gravitationally bound regions. These data will provide valuable complementary information to Gaia, eROSITA, Euclid and Rubin observatory sources as well as targets for spectroscopic studies using multi-fibre and integral field spectrographs.
Implementing a palliative care screening tool in the emergency department
Creators: name: Ciani, Amanda
Publisher: name: No Publisher Supplied
Year: 2023

description: Purpose: Palliative care (PC) is a service that is often underutilized for patients with advanced chronic illnesses. Currently there is no specific policy for referrals for PC from the emergency department (ED). By implementing a screening tool for PC in the ED, these patients can be identified and referred. Implementation of an evidence-based PC screening tool will improve identification and referral of services to these patients. The purpose of this quality improvement project is to accurately screen for patients in the ED who may benefit from PC services. Methodology: The P-CaRES screening tool was implemented in a 46- bed ED in an urban area of central New Jersey. All ED providers were educated on use of the screening tool. Patients over the age of 65 that were admitted to the ED were screened for unmet PC needs using the P-CaRES screening tool. Chart reviews were conducted to determine if screening, referrals, and consults for PC were affected by the implementation of the P-CaRES screening tool in the ED. Results: In total 1208 patients over the age of 65 were seen in the ED over a two- month period and 33.4% were screened using the P-CaRES screening tool. During this time 22.1% screened positive for unmet PC needs and 27% of those screening positive were admitted to the hospital. Referrals for PC consultation were made for 92.3% of patients admitted to the hospital that screened positive for unmet PC needs. A total of 7.4% of patients admitted to the ED during the two-month period received a PC consult. A chi-squared statistical test for analysis was run to compare referral and consultation rates in the pre and post implementation periods. Results of the chi-squared test for referral rates showed a p value of 0.004 concluding there is a statistically significant difference in referral rates before and after the implementation of the P-CaRES screening tool with an increase in referrals after implementation. The chi- squared test for consult rates showed a p value of 0.592 concluding there was not a statistically significant difference in consultations before and after implementation. Implications for Practice: Screening for PC in the ED can increase referral rates for PC in a timely manner. Screening patients for PC in the ED can reduce symptoms, improve outcomes for patients and their families, improve quality of life and decrease resource utilization.

description: We study vacuum masses of charmonia and the charm-quark diffusion coefficient in the quark-gluon plasma based on the spectral representation for meson correlators. To calculate the correlators, we solve the quark gap equation and the inhomogeneous Bethe-Salpeter equation in the rainbow-ladder approximation. It is found that the ground-state masses of charmonia in the pseudoscalar, scalar, and vector channels can be well described. For $1.5\,T_c

description: The National Principles for Child Safe Organisations provide a national approach to embedding a child-safe culture across all sectors of Australian society in which children are involved. The national principles were developed in response to recommendations by the Royal Commission into Institutional Responses to Child Sexual Abuse. The Royal Commission uncovered shocking abuse of children. In response to practices that harmed children, the national principles aim for an outcome that is universally desired - safe happy and engaged children. Psychologists are in a fortunate position of working with children and young people in a variety of work places - clinical practice, schools, hospitals, community organisations. In your practice, you can contribute to the treatment and management of the impact of child sexual abuse, and you can also draw on your understanding of the conditions that prevent abuse from occurring. A nationally consistent approach to embedding child safe cultures within organisations that engage with children ensures better protection for Australia’s children.
Meta-work and the analogous Jarzynski relation in ensembles of dynamical trajectories

description: Recently there has been growing interest in extending the thermodynamic method from static configurations to dynamical trajectories. In this approach, ensembles of trajectories are treated in an analogous manner to ensembles of configurations in equilibrium statistical mechanics: generating functions of dynamical observables are interpreted as partition sums, and the statistical properties of trajectory ensembles are encoded in free-energy functions that can be obtained through large-deviation methods in a suitable large time limit. This establishes what one can call a 'thermodynamics of trajectories'. In this paper we go a step further, and make a first connection to fluctuation theorems by generalising them to this dynamical context. We show that an effective 'meta-dynamics' in the space of trajectories gives rise to the celebrated Jarzynski relation connecting an appropriately defined 'meta-work' with changes in dynamical generating functions. We demonstrate the potential applicability of this result to computer simulations for two open quantum systems, a two-level system and the micromaser. We finally discuss the behavior of the Jarzynski relation across a first-order trajectory phase transition.

description: We consider a Boltzmann model introduced by Bertin, Droz and Greegoire as a binary interaction model of the Vicsek alignment interaction. This model considers particles lying on the circle. Pairs of particles interact by trying to reach their mid-point (on the circle) up to some noise. We study the equilibria of this Boltzmann model and we rigorously show the existence of a pitchfork bifurcation when a parameter measuring the inverse of the noise intensity crosses a critical threshold. The analysis is carried over rigorously when there are only finitely many non-zero Fourier modes of the noise distribution. In this case, we can show that the critical exponent of the bifurcation is exactly 1/2. In the case of an infinite number of non-zero Fourier modes, a similar behavior can be formally obtained thanks to a method relying on integer partitions first proposed by Ben-Naim and Krapivsky.

description: We show global well-posedness in energy norm of the semi-relativistic Schrödinger-Poisson system of equations with attractive Coulomb interaction in ${\mathbb R}^3$ in the presence of pseudo-relativistic diffusion. We also discuss sufficient conditions to have well-posedness in ${\mathcal L}^2$. In the absence of dissipation, we show that the solution corresponding to an initial condition with negative energy blows up in finite time, which is as expected, since the nonlinearity is critical.
