description: We present the analysis of high-resolution images of MOA-2013-BLG-220, taken with the Keck adaptive optics system 6 years after the initial observation, identifying the lens as a solar-type star hosting a super-Jupiter mass planet. The masses of planets and host-stars discovered by microlensing are often not determined from light curve data, while the star-planet mass-ratio and projected separation in units of Einstein ring radius are well measured. High-resolution follow-up observations after the lensing event is complete can resolve the source and lens. This allows direct measurements of flux, and the amplitude and direction of proper motion, giving strong constraints on the system parameters. Due to the high relative proper motion, $μ_{\rm rel,Geo} = 12.62\pm0.11$ mas/yr, the source and lens were resolved in 2019, with a separation of $77.1\pm0.5$ mas. Thus, we constrain the lens flux to $K_{\rm Keck,lens}= 17.92\pm0.02$. By combining constraints from the model and Keck flux, we find the lens mass to be $M_L = 0.88\pm0.05\ M_\odot$ at $D_L = 6.72\pm0.59$ kpc. With a mass-ratio of $q=(3.00\pm0.03)\times10^{-3}$ the planet's mass is determined to be $M_P = 2.74\pm0.17\ M_{J}$ at a separation of $r_\perp = 3.03\pm0.27$ AU. The lens mass is much higher than the prediction made by the Bayesian analysis that assumes all stars have an equal probability to host a planet of the measured mass ratio, and suggests that planets with mass ratios of a few 10$^{-3}$ are more common orbiting massive stars. This demonstrates the importance of high-resolution follow-up observations for testing theories like these.

description: Using a reference molecular atlas to ensure self-consistency of wavelength calibration is widespread practice. Boesch \& Reiners (Astronomy \& Astrophysics 582 A43 (2015)) reported a line list from a discharge of molecular nitrogen from 4500 to 11000 cm$^{-1}$ for this purpose. With a hollow-cathode discharge source, we have extended the experimental spectrum up to 15700 cm$^{-1}$, to include the range of Ti:sapphire lasers, since the density of N 2 lines is greater than atomic atlases in common use. Recognizing that experimental conditions can vary, we have also analysed the spectra (comprising several B ${}^3Π_g-A\ {}^3Σ_u^+$ , B' ${}^3Σ_u - B\ {}^3Π_g$, and W ${}^3Δ_u-B\ {}^3Π_g N_2$ bands) with standard Hamiltonians, so that any part of the discharge spectrum 4500-15700 cm$^{-1}$ can be simulated. Parameters are given to do this with the spectral simulation and analysis package PGOPHER. (C. Western, J. Quant. Spectrosc. Rad. Transf., 186, 221 (2016)). The analysis also included high-level ab initio calculations of potential energy curves, transition moments and spin-orbit coupling constants and these were used in preparing the model, extending the potential range of applicability. The results are available in a variety of formats to suit possible applications, including the experimental spectrum in ASCII, a detailed line list with positions and Einstein A coefficients, and a PGOPHER input file to synthesize the spectrum at selectable temperature and resolution. 2

description: As college and university archives grapple with donations of born-digital materials, they have yet to establish best practices and workflows for personally collected data such as that collected by lifeloggers or smartphones. Future acquisitions and accessions may see a shift in selection from what a donor created or collected, to data created about the donor. This article will explore existing practices for collecting and archiving personal digital data, as well as envision future collections and the roles college and university archives will play in preserving personal data.

description: We model the potential efficiency and distributional consequences of a government beverage-size restriction that is designed to curb or reduce consumption of sugar-sweetened beverages. Unsurprisingly, we find that a credibly implemented restriction can curb consumption, particularly by “high-type” consumers who consume large amounts of sweetened beverages. Surprisingly, we find that for small to moderate restrictions that might be consistent with the magnitude of the NYC soda-ban, consumer welfare will be unaffected by the regulation. Instead, most consumption inefficiency induced welfare losses will be borne by sellers. Thus, policy debates concerning welfare losses from soft-drink sales should focus on business losses rather than consumer welfare losses.

title: Composing for Openness: Investigating the relations between improvisation, composition, and performance

description: Creative performances may be seen as a dynamic contact point between the preconceived expectations from the performers, musicians, and audience. There exists a potential tension between composer control and trust in the performers, particularly when improvised musical elements occur alongside pre-composed material. Undetermined elements within the score can have significant impact on the performance of a composition through the interpretation of the musicians. As an active composer and performer, I find this tension between control, trust, and interpretation fascinating. This thesis investigates the relationship between composition, improvisation, and performance within my own artistic practice. It traces the process of composing, performing, and recording new music for four ensemble projects, each of which opens different modes of practice and ways of weaving together fixed and open-ended aspects of music. These new compositions were designed to explore the interaction between the score and the performer through integrating improvisation to varying degrees, using what I call unfixed elements. At play throughout the dissertation are theoretical concepts of ecological systems and the process of making to provide context and terminology and to help tease out the sonic and temporal interplay of composition and improvisation. The central research question is: In what ways are improvisation, composition, and performance related and realised within my artistic practice? This question is addressed through the three sub-questions. First, what are the roles of unfixed elements within my new compositions? Second, how is compositional intention conveyed? Third, what can be learnt about the tension between control and trust in composition if we view performance as an ecological system and a process of making? There are three key contributions to new knowledge from this research study. First, a body of original compositions and recordings has been created and presents the artistic representation of the research. Second, placing this output, along with the accompanying reflection on the process, within a conceptual framework of making and ecological systems offers a perspective on how improvisation, composition, and performance can relate. And third, the study offers practical insight and tools for effectively integrating unfixed elements within ensembles featuring western classical and improvising musicians. A core feature across all three contributions is the emphasis that they place on the interaction and process of performance. As this research is multidimensional, the new knowledge that has been generated is applicable to a diversity of fields, including composition, improvisation, and performance.

description: Efficient and faithful parallel simulation of large asynchronous systems is a challenging computational problem. It requires using the concept of local simulated times and a synchronization scheme. We study the scalability of massively parallel algorithms for discrete-event simulations which employ conservative synchronization to enforce causality. We do this by looking at the simulated time horizon as a complex evolving system, and we identify its universal characteristics. We find that the time horizon for the conservative parallel discrete-event simulation scheme exhibits Kardar-Parisi-Zhang-like kinetic roughening. This implies that the algorithm is asymptotically scalable in the sense that the average progress rate of the simulation approaches a non-zero constant. It also implies, however, that there are diverging memory requirements associated with such schemes.

description: This paper presents a set of long-term productivity growth scenarios for the rice sector of the the Economic Community of West African States ECOWAS), a union of 15 West African countries. The region aims to be self-sufficient in rice by 2020 and in undertaking considerable investments aimed at improving yields. This research used the USDA Baseline Model for ECOWAS to analyze the impacts of an expansion of irrigation and increased use of fertilizer. Results suggest a boost in domestic production at lower prices, but continuing dependence on imports to satisfy consumer demand.

Using N=1 superfields, massive hyper-Kahler quotient is introduced to obtain massive N=2 (8 SUSY) nonlinear sigma models in four dimensions with T*CP(n) target manifold, which yield BPS wall solutions for the n=1 case. We also describe massive hyper-Kahler quotient of T*CP(n) by using the harmonic superspace formalism which preserves all SUSY manifestly, and BPS equations and wall solutions are obtained in the n=1 case.

description: Asteroids and other Small Solar System Bodies (SSSBs) are of high general and scientific interest in many aspects. The origin, formation, and evolution of our Solar System (and other planetary systems) can be better understood by analysing the constitution and physical properties of small bodies in the Solar System. Currently, two space missions (Hayabusa2, OSIRIS-REx) have recently arrived at their respective targets and will bring a sample of the asteroids back to Earth. Other small body missions have also been selected by, or proposed to, space agencies. The threat posed to our planet by near-Earth objects (NEOs) is also considered at the international level, and this has prompted dedicated research on possible mitigation techniques. The DART mission, for example, will test the kinetic impact technique. Even ideas for industrial exploitation have risen during the last years. Lastly, the origin of water and life on Earth appears to be connected to asteroids. Hence, future space mission projects will undoubtedly target some asteroids or other SSSBs. In all these cases and research topics, specific knowledge of the structure and mechanical behaviour of the surface as well as the bulk of those celestial bodies is crucial. In contrast to large telluric planets and dwarf planets, a large proportion of such small bodies is believed to consist of gravitational aggregates ('rubble piles') with no -- or low -- internal cohesion, with varying macro-porosity and surface properties (from smooth regolith covered terrain, to very rough collection of boulders), and varying topography (craters, depressions, ridges) [...].

description: The problem of calculating the frequencies of network motifs on three and four nodes in large networks is considered. Telecommunications networks, cell molecular networks are investigated. The sizes of the investigated networks are hundreds of thousands of nodes and connections. These networks are represented in the form of directed and undirected simple graphs. Exact calculating requires huge computational resources for such large graphs. A method for calculating the frequencies of network motifs using the Monte Carlo method with control of the accuracy of calculations is proposed. The proposed effective method minimizes the value of the coefficient of variation.

Limits of fractality: Zeno boxes and relativistic particles

Publisher: name: arXiv
Year: 2001
Subjects: subject: Quantum Physics (quant-ph)

description: Physical fractals invariably have upper and lower limits for their fractal structure. Berry has shown that a particle sharply confined to a box has a wave function that is fractal both in time and space, with no lower limit. In this article, two idealizations of this picture are softened and a corresponding lower bound for fractality obtained. For a box created by repeated measurements (à la the quantum Zeno effect), the lower bound is $Δx\sim Δt (\hbar/{mL})$ with $\Dt$ the interval between measurements and $L$ is the size of the box. For a relativistic particle, the lower bound is the Compton wavelength, $\hbar/mc$. The key step in deriving both results is to write the propagator as a sum over classical paths.
Transmission of charged nanoparticles through the DMA adverse axial electric field and its improvement

description: Charged particles can be classified according to their electrical mobility using electrical methods. These particles are often transported against an adverse electric field from a region of high electric potential to a grounded region, e.g., in the aerosol sample outlet of a differential mobility analyzer (DMA). Electrostatic losses due to the adverse electric field can be reduced using a tube made of electrostatic dissipative (ESD) materials. The transmission of charged particles through an adverse axial electric field inside the ESD tube is studied considering particle losses due to electrostatic migration and Brownian motion. The electric field inside the ESD tube is solved analytically. Assuming Hagen-Poiseuille flow, plug flow, or turbulent flow, the transmission efficiency of the charged particles is evaluated using both a simplified analytical model and Monte-Carlo simulation. Transmission efficiencies of 1.48-nm ions are measured at various flow rates and for various tube lengths. The measured transmission efficiencies agree with the results from both the analytical model and Monte-Carlo simulation. The ideal tube length for relatively high transmission efficiencies is discussed. Both the analytical model and Monte-Carlo simulation show that the recommended tube length for the test DMA is longer than a threshold value corresponding to an adverse particle electrostatic migration velocity of less than ∼20% of the average air flow velocity. Based on these findings, the sample outlet of a miniature cylindrical DMA is improved using an ESD tube. The measured penetration efficiency of 1.48-nm ions at a sheath flow rate of 25 L min−1 and an aerosol flow rate of 1.5 L min−1 is improved by 50%.

description: Dense ceramics are irreplaceable in applications requiring high mechanical stiffness, chemical and temperature resistance and low weight. To improve their toughness, ceramics can be reinforced with elongated inclusions. Recent manufacturing strategies have been developed to control the orientations of disc-like micro-particles in polymeric and ceramic matrices and to build periodic microstructures. Given the infinite number of possible microstructures available, modeling tools are required to select the potentially best design. Periodic microstructures can be involved in elastic wave scattering to dissipate mechanical energy from vibrations. In this paper, a model is proposed to determine the frequency bandgaps associated to periodic architectures in composites and ceramics and the influence of microstructural parameters are investigated. The results are used to define guidelines for the future fabrication of hard bulk ceramic materials that combine traditional ceramic properties with high vibration resistance.

description: Differentiated instruction (DI) is a teaching practice implemented in multi-ability classrooms to meet the diverse learning needs of all students. National polices such as The Disability Discrimination Act and Disability Standards for Education, together with state policies such as Queensland's P-12 Curriculum Assessment and Reporting Framework, encourage teachers to foster a classroom environment that is supported through DI-led teaching and learning practices. Due to the scarcity of research conducted in Australian secondary schools, this research study will explore how early career teachers use DI in their multi-ability classrooms. A qualitative study was conducted with six early career teachers from a secondary state school situated on the Gold Coast, Queensland. Individual semi-structured interviews were used to ask participants about their use of DI in their classrooms. Data were analysed using thematic analysis which uncovered two major themes: differentiated instruction from a preservice teacher perspective and differentiated instruction from an early career teacher perspective. Findings revealed that teachers followed the curriculum-related elements of Tomlinson's model of differentiation when using DI, both as pre-service and in-service teachers. The teachers discussed the impact of this teaching strategy on their learners' engagement, achievement, and self-efficacy, and acknowledged the teacher colleagues and school leaders in the school environment who supported them to adopt this comprehensive instructional pedagogy. However, teachers were not convinced that their teacher education courses had prepared them well enough to use DI during their professional experience placements, and they were confused between the terms "differentiated instruction" and "reasonable adjustments". Teachers discussed class sizes, inadequate planning time and duration of lessons, learner behaviour, lack of resources and professional development, and skill weakness as barriers that hindered their effective implementation of DI in their classrooms. Further research into the experiences of early career teachers and their use of this teaching pedagogy is needed to ensure that they are adequately prepared and supported to overcome possible challenges, to rectify misconceptions, and to effectively utilise DI to support and enhance the learning of all students in their classrooms.

description: Purpose: To develop a single-shot multi-slice T1 mapping method by combing simultaneous multi-slice (SMS) excitations, single-shot inversion-recovery (IR) radial fast low-angle shot (FLASH) and a nonlinear model-based reconstruction method. Methods: SMS excitations are combined with a single-shot IR radial FLASH sequence for data acquisition. A previously developed single-slice calibrationless model-based reconstruction is extended to SMS, formulating the estimation of parameter maps and coil sensitivities from all slices as a single nonlinear inverse problem. Joint-sparsity constraints are further applied to the parameter maps to improve T1 precision. Validations of the proposed method are performed for a phantom and for the human brain and liver in six healthy adult subjects. Results: Phantom results confirm good T1 accuracy and precision of the simultaneously acquired multi-slice T1 maps in comparison to single-slice references. In-vivo human brain studies demonstrate the better performance of SMS acquisitions compared to the conventional spoke-interleaved multi-slice acquisition using model-based reconstruction. Apart from good accuracy and precision, the results of six healthy subjects in both brain and abdominal studies confirm good repeatability between scan and re-scans. The proposed method can simultaneously acquire T1 maps for five slices of a human brain ($0.75 \times 0.75 \times 5$ mm$^3$) or three slices of the abdomen ($1.25 \times 1.25 \times 6$ mm$^3$) within four seconds. Conclusion: The IR SMS radial FLASH acquisition together with a non-linear model-based reconstruction enable rapid high-resolution multi-slice T1 mapping with good accuracy, precision, and repeatability.

description: We model and interpret the Kilohertz QPOs from the hydrodynamical description of accretion disk around a rapidly rotating compact strange star. The higher QPO frequency is described by the viscous effects of accretion disk leading to shocks, while the lower one is taken to be the Keplerian motion of the accreting matter. Comparing our results with the observations for two of the fastest rotating compact stellar candidates namely, 4U~1636-53 and KS 1731-260, we find that they match to a very good approximation, thus interpreting them as strange stars.

description: The localization of the contact patch by cylindrical gears is realized usually through the
flank grinding operation. This is achieved due by the continuous modification of the tooth
thickness on the pitch circle. The tooth contact by external gears, as it knows by previous
studies, will be produced between convex tooth flanks. Máté and Hollanda in [5]
proposes a new procedure of cutting cylindrical gears using a milling head whose cutting
edges are aligned on an Archimedic spiral. The meshing tooth results with a convex and a
concave flank. As a consequence the localization of the contact patch will be achieved by
modifying the surface curvature through variation of the parameters of the generating
surface. The present paper, presents a quick CAD study solution to check, if the proposed
aims in [5] is achieved. Based on the mathematical equations deduced by Máté e. a.,
using the meshing points calculated numerically, will be build the solid CAD model of the
cylindrical gears with Archimedic spiral shaped teeth, will be made a proper visual
reproduction of the contact patch during the gearing process. The presented CADanalysis
is the first step in a larger implementation of the CAD solutions, to check and
study in virtual environment future gearing solutions.

description: We screened six cobalt-based 18-VEC systems CoVSi, CoNbSi, CoTaSi (Si-group) and CoVGe, CoNbGe, CoTaGe (Ge-group) by the first-principles approach, with the motivation of stabilizing these orthorhombic phases into the cubic symmetry -- favorable for thermoelectrics. Remarkably, it was found that the Ge-group is energetically more favorable in the cubic symmetry than the hitherto orthorhombic phase. We account the cubic ground state of the Si-group to the interplay of internal pressure and covalent interactions. The principle of covalent interactions will provide an insight and could be vital in speeding the search of missing cubic half-Heusler alloys. Meanwhile, the calculated transport properties of all the systems on \textit{p}-type doping, except CoVSi, are more promising than the well-known CoTiSb. We also provide conservative estimates of the figure of merit, exceeding the CoTiSb. Based on our findings, we suggest possible new phases of ternary compounds for thermoelectric applications.

description: In this paper we continue our study of local rigidity for maps of CR submanifolds of the complex space. We provide a linear sufficient condition for local rigidity of finitely nondegenerate maps between minimal CR manifolds. Furthermore, we show higher order infinitesimal conditions can be used to give a characterization of local rigidity.

description: The linearization of structural models of random price production may be carried out by exploiting the mean-standard deviation approach under a location and scale parameter condition. As shown here, the linearization problem may be solved under widely employed assumptions on production technology (i.e., a homogeneous production function) and on the type of risk aversion (i.e., constant absolute risk aversion or constant relative risk aversion). The linear structural models proposed in this study are more practical than those developed using the expected utility approach, for several reasons. First, they remarkably reduce the cost of estimating agent risk parameters. Second, they facilitate the calculation of various analytic measures that are useful for understanding production behavior, such as the risk premium and the elasticity of supply. Third, they allow for geometric explanations of agent attitudes toward price uncertainty. These practical attributes would facilitate a structural examination of farmer production behavior in the face of price risk. Furthermore, since the location and scale parameter condition under which all the arguments in this study are made is satisfied in a large number of economic models, the structural model simplification procedure considered here would be effective for developing tractable structural models involving alternative types of randomness, such as yield and financial uncertainties.

description: Previous nonlinear fundamental pulsation models for classical Cepheids with metal content Z <= 0.02 are implemented with new computations at super-solar metallicity (Z=0.03, 0.04) and selected choices of the helium-to-metal enrichment ratio DeltaY/Delta Z. On this basis, we show that the location into the HR diagram of the Cepheid instability strip is dependent on both metal and helium abundance, moving towards higher effective temperatures with decreasing the metal content (at fixed Y) or with increasing the helium content (at fixed Z). The contributions of helium and metals to the predicted Period-Luminosity and Period-Luminosity-Color relations are discussed, as well as the implications on the Cepheid distance scale. Based on these new results, we finally show that the empirical metallicity correction suggested by Cepheid observations in two fields of the galaxy M101 may be accounted for, provided that the adopted helium-to-metal enrichment ratio is reasonably high (Delta Y/Delta Z ~ 3.5).

title: Transversus abdominis with rectus sheath plane block versus port site infiltration of local anaesthesia in emergency laparoscopic cholecystectomy. Does it reduce postoperative pain and opiate requirement?
Creators: name: Cooper, Michelle L
Publisher: name: Griffith University

Subjects: subject: laparoscopic cholecystectomy
subject: TAP/RS blocks
subject: post-operative opioid use

description: Background Laparoscopic cholecystectomy (LC) is a common procedure for symptomatic gallstone disease, however postoperative pain, nausea, and vomiting remains a significant concern1. Local anaesthetic (LA) is commonly used to infiltrate the wounds created to assist with reduction of postoperative pain. Opioid analgesia is used as a common adjunct for post operative pain. This study considers whether Transversus abdominis pain (TAP) block in conjunction with rectus sheath (RS) blocks reduce the need for opioids post LC when compared to the infiltration of LA directly to the surgical incisions. Methods A prospective block randomised controlled trial was performed on all patients who underwent emergency LC at the Gold Coast University Hospital (GCUH) between April 2022 and February 2023. Patients were allocated to receive either TAP and RS block or LA to laparoscopic port sites. Allocation was performed according to the patient's week of operation, weeks one and three TAP/RS blocks and week two and four port site LA. 40ml of ropivacaine 0.375% was used for port site infiltration and used for TAP and RS blocks. Post-operative opioid use, antiemetic use, and operative entry technique, duration of operation and length of stay (LOS) were recorded and analysed. Ethics approval was granted through the GCHHS Human Research Ethics Committee. [...]

description: Machine learning algorithms using deep architectures have been able to implement increasingly powerful and successful models. However, they also become increasingly more complex, more difficult to comprehend and easier to fool. So far, most methods in the literature investigate the decision of the model for a single given input datum. In this paper, we propose to visualize a part of the decision function of a deep neural network together with a part of the data set in two dimensions with discriminative dimensionality reduction. This enables us to inspect how different properties of the data are treated by the model, such as outliers, adversaries or poisoned data. Further, the presented approach is complementary to the mentioned interpretation methods from the literature and hence might be even more useful in combination with those.

description: This study used 38 years of annual time series data (1986-2023) to examine how Nigeria's economic growth was affected by the development of its capital market. The main focus of the investigation was the association between market capitalization (MCAP), all-share index (ASI), and GDP growth rate. The study used the Ordinary Least Squares (OLS) method and discovered that MCAP significantly boosted the GDP growth rate whereas ASI significantly lowered it. These results implied that the Nigerian stock market might not have been effectively channeling investment towards productive sectors. The study urged market participants to diversify their investment portfolios and suggested more investigation into the elements behind the ASI's detrimental effects. This study offered a modern viewpoint on the connection between the stock market and economic growth in Nigeria by using recent data
The stellar population of NGC5634. A globular cluster in the Sagittarius dSph Stream?

description: We present the first (V,V-I) Color -- Magnitude Diagram (CMD) for the poorly studied globular cluster NGC 5634. The CMD shows a steep Red Giant Branch (RGB) and a predominantly blue Horizontal Branch (HB): both these characteristics suggest a low metal content for this cluster. From the position of the RGB in the CMD we estimate [Fe/H] = -1.94 +/- 0.10 and E(B-V)=0.06 +/- 0.01. The CMD presented here reaches V\simeq 23, allowing us to obtain the first measure of the Main Sequence Turn-Off (TO) V_{TO}= 21.22 +/- 0.15 for this cluster. By combining this figure with the apparent luminosity of the Zero Age HB (ZAHB), V_{ZAHB}=17.90 +/- 0.10 we obtain Delta V^{HB}_{TO}=3.32 +/- 0.16, a value which is fully compatible with that derived for the bulk of Galactic globulars. We also derive a true distance modulus of (m-M)_0 = 17.17 +/- 0.12 corresponding to a distance of ~ 27.2 kpc. Most interestingly, the cluster is shown to have position and radial velocity fully compatible with the orbit of the Sgr dwarf spheroidal (dSph) galaxy. The similarity between the stellar populations of the cluster and the Sgr globular Ter 8 and the metal poor population of the Sgr dSph, also suggest that NGC 5634 was a former member of this disrupting galaxy, torn off by the Galactic tidal field and now lost in the Sgr Stream.
