description: The quantum stress tensor $$ is calculated in the 2+1 dimensional black hole found by Banados, Teitelboim, and Zanelli. The Greens function, from which $ $ is derived, is obtained by the method of images. For the non-rotating black hole, it is shown that $$ is finite on the event horizon, but diverges at the singularity. For the rotating solution, the stress tensor is finite at the outer horizon, but diverges near the inner horizon. This suggests that the inner horizon is quantum mechanically unstable against the formation of a singularity.

description: We show on in-plane magnetized thin films that magnetization can be switched efficiently by 180 degrees using large amplitude Rayleigh waves travelling along the hard or easy magnetic axis. Large characteristic filament-like domains are formed in the latter case. Micromagnetic simulations clearly confirm that this multi-domain configuration is compatible with a resonant precessional mechanism. The reversed domains are in both geometries several hundreds of μm^2, much larger than has been shown using spin transfer torque- or field-driven precessional switching. We show that surface acoustic waves can travel at least 1mm before addressing a given area, and can interfere to create magnetic stripes that can be positionned with a sub-micronic precision.

description: A highly selective and efficient cyclocondensation reaction for construction of various 3-substituted-2H-pyrido[1,2-a]pyrimidin-2-ones and related fused pyrimidones from allylic carbonates and 2-heteroaryl amines has been developed. The transformation involves one-pot sequential aza-Michael addition, intramolecular acyl substitution, and [1,3]-H shift. The method is catalyst free, eco-friendly, scalable, and completes within a short reaction time, with no work-up, no column purification, and demonstrate a broad functional group tolerance.

description: Near--infrared, optical and ultraviolet quasi--simultaneous observations of 11 BL Lacertae objects are reported. For all but one source the dereddened spectral flux distribution in the $8\cdot10^{13}-2\cdot10^{15}$ Hz frequency range can be described by a single power law f$_ν\propto ν^{-α}$ with average spectral index $$ = 0.88 $\pm$ 0.42 (standard deviation) plus, where relevant, the contribution of the host galaxy. In most cases the non simultaneous soft X--ray fluxes obtained by the {\it Einstein Observatory} lie on or below the extrapolation of the power law. The results are compared with the average spectral properties of other samples of BL Lacs studied separately in the IR--optical and in the UV bands. The implications for existing models of the objects are shortly discussed.

A National Study of Wellbeing of Hospital Doctors in Ireland
Creators: name: Blanaid Hayes
Publisher: name: Royal College of Surgeons in Ireland
Year: 2019
Subjects: Uncategorized

description: The working environment for hospital doctors in Ireland has undergone radical change in recent years with hospital posts becoming unattractive to doctors in training and to consultants. For young medical graduates, the tensions between training requirements and service demands have contributed to a ‘brain drain’ with over half leaving to work abroad after graduation. Many consultant posts are vacant or are filled on a temporary basis, impacting on the quality of patient care. This study sets out to fill a gap in the Irish literature by exploring the topic of wellbeing in hospital doctors. It is a mixed method study using both qualitative and quantitative techniques. The first research question (what are the most significant workplace stressors to which hospital doctors in the Irish public hospital setting are exposed?) was explored using the Delphi methodology. This allowed individual opinion from a geographically dispersed population to be gathered efficiently and transformed into consensus. This study found that senior doctors and doctors in training are concerned about issues impacting on the quality of patient care and both feel undervalued in the work that they do. Consultants also express concern about the quality of healthcare management while trainees struggle with the impact of training and service delivery on their personal lives. The second research question (what is the level of wellbeing in hospital doctors in Ireland?) used a standard quantitative methodology to determine levels of personal wellbeing, workplace wellbeing and lifestyle behaviours. The survey had a national scope and a response rate of 55%. Respondents had a high prevalence of psychological distress and low levels of wellbeing as measured by standard instruments, as well as evidence of poor workplace wellbeing. Cluster analysis identified that both consultants and trainees with a negative experience of work had high levels of emotional exhaustion, overcommitment and effort–reward imbalance. They rated their workability levels as insufficient and had poor work-life balance. They were more likely to be physically inactive then their more contented colleagues.
xDH double hybrid functionals can be qualitatively incorrect for non-equilibrium geometries: Dipole moment inversion and barriers to radical-radical association using XYG3 and XYGJ-OS

description: Double hybrid (DH) density functionals are amongst the most accurate density functional approximations developed so far, largely due to incorporation of correlation effects from unoccupied orbitals via second order perturbation theory (PT2). The xDH family of DH functionals calculate energy directly from orbitals optimized by a lower level approach like B3LYP, without self-consistent optimization. XYG3 and XYGJ-OS are two widely used xDH functionals that are known to be quite accurate at equilibrium geometries. Here, we show that the XYG3 and XYGJ-OS functionals can be ill behaved for stretched bonds well beyond the Coulson-Fischer point, predicting unphysical dipole moments and humps in potential energy curves for some simple systems like the HF molecule. Numerical experiments and analysis show these failures are not due to PT2. Instead, a large mismatch at stretched bond-lengths between the reference B3LYP orbitals and the optimized orbitals associated with the non-PT2 part of XYG3 lead to an unphysically large non-Hellman-Feynman contribution to first order properties like forces and electron densities.

description: The variability in width, height, and spatial orientation of a spinal pedicle makes pedicle screw insertion a delicate operation. The aim of the current paper is to describe a computer-assisted surgical navigation system based on fluoroscopic X-ray image calibration and three-dimensional optical localizers in order to reduce radiation exposure while increasing accuracy and reliability of the surgical procedure for pedicle screw insertion. Instrumentation using transpedicular screw fixation was performed: in a first group, a conventional surgical procedure was carried out with 26 patients (138 screws); in a second group, a navigated surgical procedure (virtual fluoroscopy) was performed with 26 patients (140 screws). Evaluation of screw placement in every case was done by using plain X-rays and post-operative computer tomography scan. A 5 per cent cortex penetration (7 of 140 pedicle screws) occurred for the computer-assisted group. A 13 per cent penetration (18 of 138 pedicle screws) occurred for the non computer-assisted group. The radiation running time for each vertebra level (two screws) reached 3.5 s on average in the computer-assisted group and 11.5 s on average in the non computer-assisted group. The operative time for two screws on the same vertebra level reaches 10 min on average in the non computer-assisted group and 11.9 min on average in the computer-assisted group. The fluoroscopy-based (two-dimensional) navigation system for pedicle screw insertion is a safe and reliable procedure for surgery in the lower thoracic and lumbar spine.

description: In clinical endpoint bioequivalence (BE) studies, the primary analysis for assessing equivalence between a generic and an innovator product is based on the observed per-protocol (PP) population (usually completers and compliers). However, missing data and noncompliance are post-randomization intercurrent events and may introduce selection bias. Therefore, PP analysis is generally not causal. The FDA Missing Data Working Group recommended using “causal estimands of primary interest.” In this paper, we propose a principal stratification causal framework and co-primary causal estimands to test equivalence, which was also recommended by the recently published ICH E9 (R1) addendum to address intercurrent events. We identify three conditions under which the current PP estimator is unbiased for one of the proposed co-primary causal estimands – the “Survivor Average Causal Effect” (SACE) estimand. Simulation shows that when these three conditions are not met, the PP estimator is biased and may inflate Type 1 error and/or change power. We also propose a tipping point sensitivity analysis to evaluate the robustness of the current PP estimator in testing equivalence when the sensitivity parameters deviate from the three identified conditions, but stay within a clinically meaningful range. Our work is the first causal equivalence assessment in equivalence studies with intercurrent events.
Amplitudes of Stellar Oscillations: The Implications for Asteroseismology

description: There are no good predictions for the amplitudes expected from solar-like oscillations in other stars. In the absence of a definitive model for convection, which is thought to be the mechanism that excites these oscillations, the amplitudes for both velocity and luminosity measurements must be estimated by scaling from the Sun. In the case of luminosity measurements, even this is difficult because of disagreement over the solar amplitude. This last point has lead us to investigate whether the luminosity amplitude of oscillations (dL/L) can be derived from the velocity amplitude v_osc. Using linear theory and observational data, we show that p-mode oscillations in a large sample of pulsating stars satisfy (dL/L)_bol proportional to v_osc/T_eff. Using this relationship, together with the best estimate of v_osc(Sun) = (23.4 +/- 1.4) cm/s, we estimate the luminosity amplitude of solar oscillations at 550 nm to be dL/L = (4.7 +/- 0.3) ppm. Next we discuss how to scale the amplitude of solar-like (i.e., convectively-powered) oscillations from the Sun to other stars. The only predictions come from model calculations by (Christensen-Dalsgaard & Frandsen, Sol. Phys. 82, 469). However, their grid of stellar models is not dense enough to allow amplitude predictions for an arbitrary star. Nevertheless, although convective theory is complicated, we might expect that the general properties of convection -- including oscillation amplitudes -- should change smoothly through the colour-magnitude diagram. Indeed, we find that the velocity amplitudes predicted by the model

description: Previously we calculated the binding energies of the triton and hypertriton, using an SU_6 quark-model interaction derived from a resonating-group method of two baryon clusters. In contrast to the previous calculations employing the energy-dependent interaction kernel, we present new results using a renormalized interaction, which is now energy independent and reserves all the two-baryon data. The new binding energies are slightly smaller than the previous values. In particular the triton binding energy turns out to be 8.14 MeV with a charge-dependence correction of the two-nucleon force, 190 keV, being included. This indicates that about 350 keV is left for the energy which is to be accounted for by three-body forces.

description: In the standard scenario, the electroweak phase transition is a first order phase transition which completes by the nucleation of critical bubbles. Recently, there has been speculation that the standard picture of the electroweak phase transition is incorrect. Instead, it has been proposed that throughout the phase transition appreciable amounts of both broken and unbroken phases of $SU(2)$ coexist in equilibrium. I argue that this can not be the case. General principles insure that the universe will remain in a homogenous state of unbroken $SU(2)$ until the onset of critical bubble production.

description: The analysis in the paper focuses on global trends in total factor productivity (TFP) growth and some of its key components and drivers. The relative performance of the UK in relation to many key countries with globally important agri-food sectors, either or both as exporters and or importers of agricultural products, and as potential targets of its future UK post-Brexit strategy are examined. Two approaches are explored in order to gain some insights into productivity growth and its measurement: the decomposition output growth through the contributions of growth in land, labour, capital, material inputs and TFP, and modelling output growth to identify the significant contributing variables. Finally, the challenges that the agricultural sector of the might face as a consequence of its proposed UK post Brexit agricultural policy (if and when it might happen) for its productivity are considered and some conclusions regarding the relevance to future agri-technology developments are outlined.
A Hardware-Efficient Analog Network Structure for Hybrid Precoding in Millimeter Wave Systems

description: Hybrid precoding has been recently proposed as a cost-effective transceiver solution for millimeter wave (mm-wave) systems. While the number of radio frequency (RF) chains has been effectively reduced in existing works, a large number of high-precision phase shifters are still needed. Practical phase shifters are with coarsely quantized phases, and their number should be reduced to a minimum due to cost and power consideration. In this paper, we propose a novel hardware-efficient implementation for hybrid precoding, called the fixed phase shifter (FPS) implementation. It only requires a small number of phase shifters with quantized and fixed phases. To enhance the spectral efficiency, a switch network is put forward to provide dynamic connections from phase shifters to antennas, which is adaptive to the channel states. An effective alternating minimization (AltMin) algorithm is developed with closed-form solutions in each iteration to determine the hybrid precoder and the states of switches. Moreover, to further reduce the hardware complexity, a group-connected mapping strategy is proposed to reduce the number of switches. Simulation results show that the FPS fully-connected hybrid precoder achieves higher hardware efficiency with much fewer phase shifters than existing proposals. Furthermore, the group-connected mapping achieves a good balance between spectral efficiency and hardware complexity.

description: If string theory controls physics at the string scale, the dynamics of the early universe before the GUT era will be governed by the low-energy string equations of motion. Studying these equations for FRW spacetimes, we find that depending on the initial conditions when the stringy era starts, and on the time when it ends, there are a wide variety of qualitatively distinct types of evolution. We classify these, and present the general solution to the equations of motion.

description: A simple and general method for the synthesis of new imidazopyridines bearing an aminopyridinyl, chromenyl, or quinolinyl moiety in the C2 position was developed. The Knoevenagel reaction between imidazo[1,2-a]pyridine-2-carbaldehyde 1 and malononitrile resulted in the formation of starting material 2. Subsequently, intramolecular cyclization between the cyano group of 2 and acetophenones, naphtols, hydroxyquinolines, or phenols, gave 3, 4, 5, and 6 compounds, respectively. This is a simple, reproducible, and environmentally friendly method of synthesizing substituted imidazopyridines using water as a solvent or under solvent-free conditions.

description: We discuss flavor-mixing probabilities and flavor ratios of high energy astrophysical neutrinos. In the first part of this paper, we expand the neutrino flavor-fluxes in terms of the small parameters U_{e3} and pi/4 - theta_{23}, and show that there are universal first and second order corrections. The second order term can exceed the first order term, and so should be included in any analytic study. We also investigate the probabilities and ratios after a further expansion around the tribimaximal value of sin^2 theta_{12} = 1/3. In the second part of the paper, we discuss implications of deviations of initial flavor ratios from the usually assumed, idealized flavor compositions for pion, muon-damped, and neutron beam sources, viz., (1 : 2 : 0), (0 : 1 : 0), and (1 : 0 : 0), respectively. We show that even small deviations have significant consequences for the observed flavor ratios at Earth. If initial flavor deviations are not taken into account in analyses, then false inferences for the values in the PMNS matrix elements (angles and phase) may result.

description: Chemical equilibrium is fully characterized at thermodynamic level by the free energy: the equilibrium is written in terms of equality of chemical potentials. Rate of chemical reactions can be calculated for ideal solutions by using mass-action equations, with reaction rate constants related to energy barriers through the transition state theory. The two approaches merge in the case of equilibrium and ideal solutions. Here, we discuss how to extend the transition state theory in the case of non-ideal solutions, i.e. of interacting particles, at equilibrium. We find bounds of the exchange reaction rate. However, we show that the value of the exchange reaction rate cannot be calculated from equilibrium thermodynamic parameters (i.e. from the free energy), i.e. it is possible to find different Hamiltonians giving the same free energy but different exchange reaction rate.

description: Using conventional refraction-based optical lens, it is challenging to achieve both high-resolution imaging and long-working-distance condition. To increase the numerical aperture of a lens, the working distance should be compensated, and vice versa. Here we propose and demonstrate a new concept in optical microscopy that can achieve both high-resolution imaging and long-working-distance conditions by utilising a scattering layer instead of refractive optics. When light passes through a scattering layer, it creates a unique interference pattern. To retrieve the complex amplitude image from the interference pattern without introducing a reference beam, we utilised a speckle-correlation scattering matrix method. This property enables holographic microscopy without any lens or external reference beam. Importantly, the proposed method allows high-resolution imaging with a long working distance beyond what a conventional objective lens can achieve. As an experimental verification, we imaged various microscopic samples and compared their performance with off-axis digital holographic microscopy.

description: The low column density gas at the outskirts of galaxies as traced by the 21 cm hydrogen line emission (HI) represents the interface between galaxies and the intergalactic medium, i.e., where galaxies are believed to get their supply of gas to fuel future episodes of star formation. Photoionization models predict a break in the radial profiles of HI at a column density of 5x10E+19 cm^-2 due to the lack of self-shielding against extragalactic ionizing photons. To investigate the prevalence of such breaks in galactic disks and to characterize what determines the potential "edge" of the HI disks, we study the azimuthally-averaged HI column density profiles of 17 nearby galaxies from The HI Nearby Galaxy Survey (THINGS) and supplemented in two cases with published Hydrogen Accretion in LOcal GAlaxieS (HALOGAS) data. To detect potential faint HI emission that would otherwise be undetected using conventional moment map analysis, we line up individual profiles to the same reference velocity and average them azimuthally to derive stacked radial profiles. To do so, we use model velocity fields created from a simple extrapolation of the rotation curves to align the profiles in velocity at radii beyond the extent probed with the sensitivity of traditional integrated HI maps. With this method, we improve our sensitivity to outer-disk HI emission by up to an order of magnitude. Except for a few disturbed galaxies, none show evidence for a sudden change in the slope of the HI radial profiles, the alleged signature of ionization by the extragalactic background.

description: Background: To address a lack of systematic epidemiological research on youth mental health in Ireland, the first large-scale cross-sectional school-based study (The Challenging Times Study) was carried out eight years ago to determine the prevalence rates of psychiatric disorders in a population of 212 urban Irish adolescents aged 12-15 years. Baseline results showed that 15.6% of the study population met criteria for a current psychiatric disorder. Eight years later the present study identified 169 of the 212 (80%) young people now aged 19-23 years. The aims of the study were to examine: 1) the mental health outcomes and social and occupational functioning of a cohort of young people (now aged 19-23 years), 2) the association between life stresses such as poor family functioning, parental separation / divorce and peer relations, substance use and anti-social behaviour and mental health outcomes in young adulthood. Method: Two hundred and twelve young people, who participated in the original Challenging Times Study, were invited to participate in an assessment interview. Mental health outcomes and social and occupational functioning were assessed using the Structured Clinical Interview for DSM-IV psychiatric diagnoses (SCID I), the Achenbach Adult Self Report and Achenbach Adult Behaviour Checklist (parental questionnaire).The Me Master Family Assessment Device was used as a measure of family functioning whilst the Global Assessment of Functioning (GAF) scale measured quality of life and general functioning. The Stressful Life Events Schedule for Children and Adolescents a semi-structured interview was used to identify factors associated with mental ill-health. Results: Using a weighted population prevalence analysis, 24.3% (22.4 - 28.9) of the young people met the criteria for a psychiatric disorder at follow-up, including 5.4% (4.1 - 7.6) with a mood disorder, 11.2% (9.5 -14.3) with an anxiety disorder, 8.2% (6.7 -11.0) with a substance use disorder and 7.7% (6.2 -10.4) with alcohol disorders. Logistic regression revealed that an adolescent diagnosis of being “at risk” of a psychiatric disorder at the Challenging Times original study was not predictive of poor mental health outcomes at follow-up. Specific stressful life events were identified as factors associated with poor mental health outcomes. Conclusion: This study offers an understanding of the prevalence rates and psychosocial factors associated with psychiatric disorders in young adulthood in an Irish context. It emphasises the need for youth mental health Intervention and prevention programmes that equip young people with the necessary coping skills to deal with life’s many challenges.

description: Cross-linked poly(methacrylic acid) (PMAA) nanoparticles synthesized by distillation precipitation polymerization (DPP) were used as polyelectrolyte seeds in seeded emulsion polymerization of 2-(dimethylamino)ethyl methacrylate (DMAEMA) and 2-hydroxyethyl methacrylate (HEMA). The use of DMAEMA and HEMA hydrophilic monomers as shell monomer fabricated a polyelectrolyte and a non-polyelectrolyte polymer in the presence of polyelectrolyte seed particles respectively. The effects of feeding approach and polymerization media on the morphology of the resulted particles were investigated. Production of polyelectrolyte and non-polyelectrolyte components in the presence of polyelectrolyte seed particles led to formation of composite particles with different morphologies including polyelectrolyte@polyelectrolyte core-shell and polyelectrolyte/non-polyelectrolyte Janus particles. Subsequently, to determine the behavior of the poly-electrolyte and non-polyelectrolyte shells, an acidic drug with the least tendency to the acidic polyelectrolyte core (vitamin C) was loaded onto synthesized PMAA seed particles and smart composite nanoparticles and its release behavior was studied in different conditions. Results showed that amount of loaded drug and release behavior depend significantly on the structure of utilized nanocarrier.
On the spin parameter of dark-matter haloes

description: The study by White (1984) on the growth of angular momentum in dark haloes is extended towards a more detailed investigation of the spin parameter $λ\equiv L\sqrt{E}/{G M^{2.5}}$. Starting from the Zel'dovich approximation to structure formation, a dark halo is approximated by a homogeneous ellipsoid with the inertial tensor of the (highly irregular) Lagrangian region $Υ$ from which the dark halo forms. Within this approximation, an expression for the spin parameter can be derived, which depends on the geometry of $Υ$, the cosmological density parameter $Ω_0$, the overdensity of the dark halo, and the tidal torque exerted on it. For Gaussian random fields, this expression can be evaluated statistically. As a result, we derive a probability distribution of the spin parameter which gives $λ\simeq0.07^{+0.04}_{-0.05}$, consistent with numerical investigations. This probability distribution steeply rises with increasing spin parameter, reaching its maximum at $λ\simeq0.025$. The 10 (50,90) percentile values are $λ=0.02$ (0.05,0.11, respectively). There is a weak anticorrelation of the spin parameter with the peak height $ν$ of the density fluctuation field $λ\propto ν^{-0.29}$. The dependence on $Ω_0$ and the variance $σ$ of the density-contrast field is very weak; there is only a marginal tendency for the spin parameter to be slightly larger for late-forming objects in an open universe. Due to the weak dependence on $σ$, our results should be quite generally applicable and independent on
