The First Spatially Resolved Mid-IR Spectra of NGC 1068 Obtained at Diffraction-limited Resolution with LWS at Keck I Telescope

description: We present spatially resolved mid-IR spectra of NGC 1068 with a diffraction-limited resolution of 0.25\arcsec using the Long Wavelength Spectrometer (LWS) at the Keck I telescope. The mid-infrared image of NGC 1068 is extended along the N-S direction. Previous imaging studies have shown the extended regions are located inside the ionization cones indicating that the mid-infrared emission arises perhaps from the inner regions of the narrow-line clouds instead of the proposed dusty torus itself. The spatially resolved mid-IR spectra were obtained at two different slit position angles, +8.0 and -13.0 degrees across the elongated regions in the mid-IR. From these spectra, we found only weak silicate absorption toward the northern extended regions but strong in the nucleus and the southern extended regions. This is consistent with a model of a slightly inclined cold obscuring torus which covers much of the southern regions but is behind the northern extension. While a detailed analysis of the spectra requires a radiative transfer model, the lack of silicate emission from the northern extended regions prompts us to consider a dual dust population model as one of the possible explanations in which a different dust population exists in the ionization cones compared to that in the dusty torus. Dust inside the ionization cones may lack small silicate grains giving rise to only a featureless continuum in the northern extended regions while dust in the dusty torus has plenty of small silicate grains to produce the strong silicate absorption lines towards the nucleus and the southern extended regions.

description: We investigated the dynamics of a series of room temperature ionic liquids based on the same 1-butyl-3-methyl imidazolium cation and different anions by means of broadband dielectric spectroscopy covering 15 decades in frequency (10^(-6)-10^9 Hz), and in the temperature range from 400 K down to 35 K. An ionic conductivity is observed above the glass transition temperature T_{g} with a relaxation in the electric modulus representation. Below T_{g}, two relaxation processes appear, with the same features as the secondary relaxations typically observed in molecular glasses. The activation energy of the secondary processes and their dependence on the anion are different. The slower process shows the characteristics of an intrinsic Johari-Goldstein relaxation, in particular an activation energy E_{beta}=24k_{B}T_{g} is found, as observed in molecular glasses.

description: Mark's talk focused on three specific areas as to how you can digitise your data and workflows to improve your productivity, increase discovery of your data and make your research more reproducible. These tips were broken down into smaller areas in which you could implement them, with examples taken from the chemistry and life sciences domains. The three main areas which Mark included in his tips were: binning the old fashioned write up, collecting data throughout the whole experiment and sharing your data in accessible and transferable formats. The talk gave examples using the Digital GlasswareTM products offered by DeepMatter, in addition to ways to incorporate the tips in different systems. Mark concludes his talk by commenting on the large proportion of science that is currently irreproducible and the ways in which human interaction introduces opportunities for error. These tips aim to resolve these issues, increasing the reproducibility of science and reducing the errors.

description: Radiation damage in lead tungstate crystals reduces their transparency. The calibration that relates the amount of light detected in such crystals to incident energy of photons or electrons is of paramount importance to maintaining the energy resolution the detection system. We report on tests of lead tungstate crystals, read out by photomultiplier tubes, exposed to irradiation by monoenergetic electron or pion beams. The beam electrons themselves were used to measure the scintillation light output, and a blue light emitting diode (LED) was used to track variations of crystals transparency. We report on the correlation of the LED measurement with radiation damage by the beams and also show that it can accurately monitor the crystals recovery from such damage.

Addressing issues of competency in older adults when discharge planning : a social work perspective
Creators: name: Torontali, Sarah Ann
Publisher: name: University of British Columbia
Year: 2009

description: An aging Canadian population suggests that social workers in hospital settings will increasingly encounter older adults whose capacity to make decisions regarding place of residence may be impaired. There is a lack of discussion in the social work literature around the issue of competency to make this decision, specifically, how competency is determined, and how the assessment process unfolds. Qualitative research was conducted in order to explore the process of discharge planning with elderly, hospitalized patients, when there are concerns about their competency to make decisions regarding place of residence. The results of this research highlight the key role social workers play in both informal and formal assessments of competency in elderly patients. The findings suggest that competency to decide place of residence was based on the patient's mental capacity, as well as his/her ability to function in the chosen environment. As a result, an assessment of risk was integral to the assessment of competency and discharge planning. The assessment of risk, and thus the assessment of competency, are highly subjective processes, influenced by the values of the assessor, the organizational context, and the societal and legislative context. The research also emphasized that formal competency assessments were used as a last resort, due in part to the gaps in the current legislative context. This research provides an emerging social work perspective which was previously untold, and establishes a basis from which to further develop knowledge in this intriguing and important area for social work practice.

description: A homogeneous sample of ~2200 low redshift disk galaxies with both high sensitivity long-slit optical spectroscopy and detailed I-band photometry is used to construct average, or template, rotation curves in separate luminosity classes, spanning 6 magnitudes in I-band luminosity. The template rotation curves are expressed as functions both of exponential disk scale lengths r_d and of optical radii Ropt, and extend out to 4.5-6.5 r_d, depending on the luminosity bin. The two parameterizations yield slightly different results beyond Ropt because galaxies whose Halpha emission can be traced to larger extents in the disks are typically of higher optical surface brightness and are characterized by larger values of Ropt/r_d. By either parameterization, these template rotation curves show no convincing evidence of velocity decline within the spatial scales over which they are sampled, even in the case of the most luminous systems. In contrast to some previous expectations, the fastest rotators (most luminous galaxies) have, on average, rotation curves that are flat or mildly rising beyond the optical radius, implying that the dark matter halo makes an important contribution to the kinematics also in these systems. The template rotation curves and the derived functional fits provide quantitative constraints for studies of the structure and evolution of disk galaxies, which aim at reproducing the internal kinematics properties of disks at the present cosmological epoch.

Thermodynamics of five-dimensional Schwarzschild black holes in the canonical ensemble

description: We study the thermodynamics of a five-dimensional Schwarzschild black hole in the canonical ensemble using York's formalism. Inside a cavity of fixed size $r$ and fixed temperature $T$, there is a threshold at $πr T = 1$ above which a black hole can be in thermal equilibrium. This thermal equilibrium can be achieved for two specific black holes, a small black hole of horizon radius $r_{+1}$, and a large black hole of radius $r_{+2}$. In five dimensions, the radii $r_{+1}$ and $r_{+2}$ have an exact expression. Through the path integral formalism and the partition function, one obtains the action and the free energy. This leads to the thermal energy and entropy of the system, the latter turning out to be given by the Bekenstein-Hawking area law $S = \frac{A_{+}}{4}$, where $A_+$ is the black hole's surface area. The heat capacity is positive when the heat bath is placed at a radius $r$ that is equal or less than the photonic orbit, implying thermodynamic stability. This means that the small black hole is unstable and the large one is stable. A generalized free energy is used to show that it is feasible that classical hot flat space transits through $r_{+1}$ to settle at the stable $r_{+2}$. Remarkably, the free energy of the larger $r_{+2}$ black hole is zero when the cavity radius is equal to the Buchdahl radius. The relation to the instabilities that arise due to perturbations in the path integral in the instanton solution is mentioned. Quantum hot flat space has negative free energy and we find the conditions for which the large black hole, quantum hot flat space, or both are the ground state. The corresponding phase diagram is displayed. Using the density of states $ν$ at a given energy $E$ we also find that the entropy of the large black hole $r_{+2}$. In addition, we make the connection between the five-dimensional thermodynamics and York's four-dimensional results.

description: We show that any unitary transformation performed on the quantum state of a closed quantum system, describes an inner, reversible, generalized quantum measurement. We also show that under some specific conditions it is possible to perform a unitary transformation on the state of the closed quantum system by means of a collection of generalized measurement operators. In particular, given a complete set of orthogonal projectors, it is possible to implement a reversible quantum measurement that preserves the probabilities. In this context, we introduce the concept of "Truth-Observable", which is the physical counterpart of an inner logical truth.

description: Recent work found an enhanced correction to the entanglement entropy of a subsystem in a chaotic energy eigenstate. The enhanced correction appears near a phase transition in the entanglement entropy that happens when the subsystem size is half of the entire system size. Here we study the appearance of such enhanced corrections holographically. We show explicitly how to find these corrections in the example of chaotic eigenstates by summing over contributions of all bulk saddle point solutions, including those that break the replica symmetry. With the help of an emergent rotational symmetry, the sum over all saddle points is written in terms of an effective action for cosmic branes. The resulting Renyi and entanglement entropies are then naturally organized in a basis of fixed-area states and can be evaluated directly, showing an enhanced correction near holographic entanglement transitions. We comment on several intriguing features of our tractable example and discuss the implications for finding a convincing derivation of the enhanced corrections in other, more general holographic examples.

description: We investigate the effects of the addition of pre-main sequence evolution to star cluster simulations. We allowed stars to follow pre-main sequence tracks that begin at the deuterium burning birthline and end at the zero age main sequence. We compared our simulations to ones in which the stars began their lives at the zero age main sequence, and also investigated the effects of particular choices for initial binary orbital parameters. We find that the inclusion of the pre-main sequence phase results in a slightly higher core concentration, lower binary fraction, and fewer hard binary systems. In general, the global properties of star clusters remain almost unchanged, but the properties of the binary star population in the cluster can be dramatically modified by the correct treatment of the pre-main sequence stage.

description: Although extensive behavioral changes often exist between closely related animal species, our understanding of the genetic basis underlying the evolution of behavior has remained limited. Here, we propose a new framework to study behavioral evolution by computational estimation of ancestral behavioral repertoires. We measured the behaviors of individuals from six species of fruit flies using unsupervised techniques and identified suites of stereotyped movements exhibited by each species. We then fit a Generalized Linear Mixed Model to estimate the suites of behaviors exhibited by ancestral species, as well as the intra- and inter-species behavioral covariances. We found that much of intraspecific behavioral variation is explained by differences between individuals in the status of their behavioral hidden states, what might be called their "mood." Lastly, we propose a method to identify groups of behaviors that appear to have evolved together, illustrating how sets of behaviors, rather than individual behaviors, likely evolved. Our approach provides a new framework for identifying co-evolving behaviors and may provide new opportunities to study the genetic basis of behavioral evolution.

description: We study the heating dynamics of a generic one dimensional critical system when driven quasiperiodically. Specifically, we consider a Fibonacci drive sequence comprising the Hamiltonian of uniform conformal field theory (CFT) describing such critical systems and its sine-square deformed counterpart. The asymptotic dynamics is dictated by the Lyapunov exponent which has a fractal structure embedding Cantor lines where the exponent is exactly zero. Away from these Cantor lines, the system typically heats up fast to infinite energy in a non-ergodic manner where the quasiparticle excitations congregate at a small number of select spatial locations resulting in a build up of energy at these points. Periodic dynamics with no heating for physically relevant timescales is seen in the high frequency regime. As we traverse the fractal region and approach the Cantor lines, the heating slows enormously and the quasiparticles completely delocalise at stroboscopic times. Our setup allows us to tune between fast and ultra-slow heating regimes in integrable systems.

The internal rate of return to research was estimated to be in the range of 15 to 40 percent which does not provide strong evidence that Australia is either under- or over-investing in public research.

We detect $^{12}$CO~$J$=4--3 toward the northern part of NGC 6052, but [\ion{C}{1}]~$^3P_1$--$^3P_0$ is not detected with a [\ion{C}{1}]~$^3P_1$--$^3P_0$ to $^{12}$CO~$J$=4--3 line luminosity ratio of$~\lesssim0.07$. According to models of photodissociation regions, the unusual weakness of [\ion{C}{1}]~$^3P_1$--$^3P_0$ relative to $^{12}$CO~$J$=4--3 can be explained if the interstellar medium has a hydrogen density larger than $10^5\,{\rm cm}^{-3}$, conditions that might arise naturally in the ongoing merging process in NGC 6052. Its [\ion{C}{1}]~$^3P_1$--$^3P_0$ emission is also weaker than expected given the molecular gas mass inferred from previous measurements of $^{12}$CO~$J$=1--0 and $^{12}$CO~$J$=2--1. This suggests that [\ion{C}{1}]~$^3P_1$--$^3P_0$ may not be a reliable tracer of molecular gas mass in this galaxy. NGC 6052 is a unique laboratory to investigate how the merger process impacts the molecular gas distribution.

description: Structure formation shocks are believed to be the largest accelerators of cosmic rays in the Universe. However, little is still known about their efficiency in accelerating relativistic electrons and protons as a function of their magnetization properties, i.e. of their magnetic field strength and topology. In this work, we analyzed both uniform and adaptive mesh resolution simulations of large-scale structures with the magnetohydrodynamical grid code Enzo, studying the dependence of shock obliquity with different realistic scenarios of cosmic magnetism. We found that shock obliquities are more often perpendicular than what would be expected from a random three-dimensional distribution of vectors, and that this effect is particularly prominent in the proximity of filaments, due to the action of local shear motions. By coupling these results to recent works from particle-in-cell simulations, we estimated the flux of cosmic-ray protons in galaxy clusters, and showed that in principle the riddle of the missed detection of hadronic gamma-ray emission by the Fermi-LAT can be explained if only quasi-parallel shocks accelerate protons. On the other hand, for most of the cosmic web the acceleration of cosmic-ray electrons is still allowed, due to the abundance of quasi-perpendicular shocks. We discuss quantitative differences between the analyzed models of magnetization of cosmic structures, which become more significant at low cosmic overdensities.

description: The high costs and effectiveness of Indonesia's current mix of policies aimed at maintaining rice self-sufficiency, for example fertiliser and other subsidies, has been questioned. Consequently, attention has turned to developing policies to increase farmers yields through efficiencies, for example as a result of better extension. The main issue investigated in this article is whether existing yields can be significantly improved through increasing the efficiency of individual farmers. Production frontiers are estimated and technical efficiencies/inefficiencies predicted from panel data and for one year at a time. Different results are explained in relation to a number of aspects, especially the rate of adoption of new technologies, and policy actions are recommended. The robustness of the analysis is examined as conclusions obtained from past analyses have often been inconsistent.

description: Occupational noise exposure is a significant concern for fish harvesters because it can cause severe health problems such as hearing loss, hypertension, stress, anxiety, and sleep disorders. The study investigates the perceptions of noise and self-reported hearing loss among fish harvesters in Newfoundland and Labrador. A mixed-methods research was conducted. A pre-validated survey tool was adopted to assess perceived noise risks and self-reported hearing loss. Semi-structured telephone interviews were conducted to explore noise exposure and associated health problems as well as obstacles and challenges for fishing workers to take noise reduction measures. Data were collected through 76 survey responses and twelve interviews. Through measuring the perceived benefits, barriers, and self-efficacy score (2.3 to 2.9 out of 5), this research finds a moderately positive attitude of harvesters toward noise reduction and hearing loss prevention. A high perceived attitude and susceptibility score (3.9 to 4.5) suggests that fish harvesters disliked the loud noise and were susceptible to hearing loss. Most interviewees agreed that their workplace is noisy. A conflict between vessel safety and individual health was observed, as participants reported that the reason to avoid wearing hearing protectors is due to various other safety concerns. Participants believe that increasing education, awareness, and training can reduce noise exposure and prevent hearing loss.

description: Planetary systems with sufficiently small orbital spacings can experience planetary mergers and ejections. The branching ratio of mergers vs ejections depends sensitively on the treatment of planetary close encounters. Previous works have adopted a simple "sticky-sphere" prescription, whose validity is questionable. We apply both smoothed particle hydrodynamics and $N$-body integrations to investigate the fluid effects in close encounters between gas giants and the long-term evolution of closely-packed planetary systems. Focusing on parabolic encounters between Jupiter-like planets with $M_J$ and $2M_J$, we find that quick mergers occur when the impact parameter $r_p$ (the pericenter separation between the planets) is less than $2R_J$, and the merger conserved 97% of the initial mass. Strong tidal effects can affect the "binary-planet" orbit when $r_p$ is between $2R_J$ and $4R_J$. We quantify these effects using a set of fitting formulae that can be implemented in $N$-body codes. We run a suite of $N$-body simulations with and without the formulae for systems of two giant planets initially in unstable, nearly circular coplanar orbits. The fluid (tidal) effects significantly increase the branching ratio of planetary mergers relative to ejections by doubling the effective collision radius. While the fluid effects do not change the distributions of semi-major axis and eccentricity of each type of remnant planets (mergers vs surviving planets in ejections), the overall orbital properties of planet scattering remnants are strongly affected due to the change in the branching ratio. We also find that the merger products have broad distributions of spin magnitudes and obliquities.

description: Purpose of Project: The purpose of this project was to evaluate the effectiveness of an evidence-based intervention in reducing 30-day readmission rates among post hospital discharge heart failure patients in a Medical Group. Methodology: This project utilized a retrospective exploratory design to evaluate the effectiveness of an evidence-based intervention to reduce 30-day readmission rates among post hospital discharge HF patients in the Medical Group. A descriptive comparative analysis was conducted on outcomes data from pre-implementation, June 2017-June 2018 and post-implementation, July 2018-December 2019, in order to evaluate the intervention.Results: During the pre-implementation period (June 2017-June 2018) the twelve patients who qualified for the study had been re-admitted on several occasions. Of the twelve, six had never been hospitalized, four patients were readmitted within 30 days of discharge, but one patient had multiple visits to the emergency room (ER). After the implementation of the transition care intervention, readmission rates, including hospitalization and visits to the ER, were reduced to zero. In addition, the patient who had multiple visits to the ER, was not readmitted to the hospital or had to visit the ER within 30 days after the intervention. With four patients, who were readmitted within 30 days during the pre-implementation period, the readmission rate was 33%. There were no readmissions within 30 days post implementation. Overall, there was an improvement in reducing readmission rates within 30 days after the implementation of the transition care intervention in the Medical Group.Implications for Practice: By implementing the TCI, it can potentially utilize by the hospitals, medical groups, and homecare agencies to reduce readmission rates of patients with HF. The TCI will be beneficial to improve quality of care, increase patient outcomes and increase patients’ satisfaction. Lastly, the TCI will be beneficial for the organization in reducing healthcare costs due to readmission rates posthospital discharge.
DEREGULATION AND EFFICIENCY IN GRAIN TRANSPORT

description: In this paper, it is argued that removing restrictions on road transport will not be sufficient to encourage efficiency improvements in grain freight industry while rail authorities continue to operate as public monopolies. This is because of the structure of costs in the grain freight industry, which imply that road transport cannot compete with rail transport in areas where road is the more efficient mode. While the tendency for a regulated monopoly to cross-subsidise inefficient operations is common place, the focus in this analysis is on the nature of the cross-subsidy in the grain freight industry, and shows that it is a type of cross-subsidy that is well hidden by aggregation. A model of investment in a rail network is presented where the monopoly power afforded to the rail industry is shown to be due to economies of traffic density. A case study of the grain rail network in Western Australia is presented where it is shown that the rail authority has been able to maintain very uneconomic sections of rail line, despite the introduction of road competition and apparently competitive pricing practices.

description: The role of ion-ion correlations in suppressing neutrino-nucleus elastic scattering during stellar core collapse is reinvestigated, using two different equations of state. We test the improved description by Itoh et al. against the treatment suggested by Horowitz and find that the stronger cross section reduction for small momentum transfer in the former case does not lead to noticeable changes of the core deleptonization and entropy increase during collapse, because the improvements are relevant below neutrino trapping conditions only for very low neutrino energies, corresponding to a very small phase space volume. Treating screening effects for ionic mixtures by the linear mixing rule, applied to the collection of representative heavy nucleus, alpha particles, and free nucleons, which is assumed to characterize the composition in nuclear statistical equilibrium, we cannot determine mentionable differences during stellar collapse, because alpha particles are not sufficiently abundant and their coherent scattering opacity is too small.

description: The literature shows that the influence of yield uncertainty on production relative to quota is ambiguous in the case of a single market. This paper uses a two-market framework (quota market and secondary market) with multiplicative yield uncertainty to show that if over-quota production in the absence of yield uncertainty is profitable, then the presence of yield uncertainty is unambiguously a further stimulus to over-quota production. The analysis is discussed in the context of recent changes to the marketing arrangements for Western Australian potatoes.

description: The detection of ultralight dark matter through interactions with nucleons, electrons, and photons has been explored in depth. In this work we propose to use precision muon experiments, specifically muon g-2 and electric dipole moment measurements, to detect ultralight dark matter that couples predominantly to muons. We set direct, terrestrial limits on DM-muon interactions using existing g-2 data, and show that a time-resolved reanalysis of ongoing and upcoming precession experiments will be sensitive to dark matter signals. Intriguingly, we also find that the current muon g-2 anomaly can be explained by a spin torque applied to muons from a pseudoscalar dark matter background that induces an oscillating electric dipole moment for the muon. This explanation may be verified by a time-resolved reanalysis.

description: A number of current policy issues are discussed which illustrate serious confusion and economic illiteracy in the minds of many influential farm leaders. The issues discussed are: the cost-price squeeze in agriculture; the embargo on the export of merino rams; promotion of farm products; land policy; and tax concessions for agriculture. In some cases policies are followed which run counter to both farmer and national interests. Along with farm management extension, there is a growing need for agricultural policy extension.

description: Origin of hydrodynamical instability and turbulence in the Keplerian accretion disc as well as similar laboratory shear flows, e.g. plane Couette flow, is a long standing puzzle. These flows are linearly stable. Here we explore the evolution of perturbation in such flows in the presence of an additional force. Such a force, which is expected to be stochastic in nature hence behaving as noise, could be result of thermal fluctuations (however small be), Brownian ratchet, grain-fluid interactions and feedback from outflows in astrophysical discs etc. We essentially establish the evolution of nonlinear perturbation in the presence of Coriolis and external forces, which is modified Landau equation. We show that even in the linear regime, under suitable forcing and Reynolds number, the otherwise least stable perturbation evolves to a very large saturated amplitude, leading to nonlinearity and plausible turbulence. Hence, forcing essentially leads a linear stable mode to unstable. We further show that nonlinear perturbation diverges at a shorter timescale in the presence of force, leading to a fast transition to turbulence. Interestingly, emergence of nonlinearity depends only on the force but not on the initial amplitude of perturbation, unlike original Landau equation based solution.

description: We present theoretical results on the interplay of magnetic and superconducting orders in diffusive ferromagnet-superconductor-ferromagnet trilayers. The induced triplet superconducting correlations throughout the trilayer lead to an induced spin magnetization. We include self-consistency of the order parameter in the superconducting layer at arbitrary temperatures, arbitrary interface transparency, and any relative orientation of the exchange fields in the two ferromagnets. We propose to use the torque on the trilayer in an external magnetic field as a probe of the presence of triplet correlations in the superconducting phase.

FUTURE AUSTRALIA-JAPAN TRADE RELATIONS

description: The leitmotif of this paper is the strong, rising and alarming trend of deficits in Australia's balance of payments current account, which makes it overwhelmingly important to increase exports. Market promotion, substantially the existing method, will not do the job in a world with politically set up trade barriers. Multilateral political negotiations about the removal of the trade barriers within the G.A.T.T. system are unlikely to help for Australia's range of exports. Therefore Australia must enter into bilateral negotiations with any likely important customer, the most obvious one being Japan, to lower trade barriers on a bilateral basis, and this under the existing international agreements can be done only under the guise of a partial free trade area.
