description: Pulsar timing arrays aim to detect nanohertz-frequency gravitational waves (GWs). A background of GWs modulates pulsar arrival times and manifests as a stochastic process, common to all pulsars, with a signature spatial correlation. Here we describe a search for an isotropic stochastic gravitational-wave background (GWB) using observations of 30 millisecond pulsars from the third data release of the Parkes Pulsar Timing Array (PPTA), which spans 18 years. Using current Bayesian inference techniques we recover and characterize a common-spectrum noise process. Represented as a strain spectrum $h_c = A(f/1 {\rm yr}^{-1})^α$, we measure $A=3.1^{+1.3}_{-0.9} \times 10^{-15}$ and $α=-0.45 \pm 0.20$ respectively (median and 68% credible interval). For a spectral index of $α=-2/3$, corresponding to an isotropic background of GWs radiated by inspiraling supermassive black hole binaries, we recover an amplitude of $A=2.04^{+0.25}_{-0.22} \times 10^{-15}$. However, we demonstrate that the apparent signal strength is time-dependent, as the first half of our data set can be used to place an upper limit on $A$ that is in tension with the inferred common-spectrum amplitude using the complete data set. We search for spatial correlations in the observations by hierarchically analyzing individual pulsar pairs, which also allows for significance validation through randomizing pulsar positions on the sky. For a process with $α=-2/3$, we measure spatial correlations consistent with a GWB, with an estimated false-alarm probability of $p \lesssim 0.02$ (approx. $2σ$). The long timing baselines of the PPTA and the access to southern pulsars will continue to play an important role in the International Pulsar Timing Array.

description: Waves and oscillations can provide vital information about the internal structure of waveguides they propagate in. Here, we analytically investigate the effects of density and magnetic stratification on linear longitudinal magnetohydrodynamic (MHD) waves. The focus of this paper is to study the eigenmodes of these oscillations. It is our specific aim is to understand what happens to these MHD waves generated in flux tubes with non-constant (e.g., expanding or magnetic bottle) cross-sectional area and density variations. The governing equation of the longitudinal mode is derived and solved analytically and numerically. In particular, the limit of the thin flux tube approximation is examined. The general solution describing the slow longitudinal MHD waves in an expanding magnetic flux tube with constant density is found. Longitudinal MHD waves in density stratified loops with constant magnetic field are also analyzed. From analytical solutions, the frequency ratio of the first overtone and fundamental mode is investigated in stratified waveguides. For small expansion, a linear dependence between the frequency ratio and the expansion factor is found. From numerical calculations it was found that the frequency ratio strongly depends on the density profile chosen and, in general, the numerical results are in agreement with the analytical results. The relevance of these results for solar magneto-seismology is discussed.

description: We investigate (local) Minkowski measurability of $\mathcal C^{1+α}$ images of self-similar sets. We show that (local) Minkowski measurability of a self-similar set $K$ implies (local) Minkowski measurability of its image $F$ and provide an explicit formula for the (local) Minkowski content of $F$ in this case. A counterexample is presented which shows that the converse is not necessarily true. That is, $F$ can be Minkowski measurable although $K$ is not. However, we obtain that an average version of the (local) Minkowski content of both $K$ and $F$ always exists and also provide an explicit formula for the relation between the (local) average Minkowski contents of $K$ and $F$.

description: Observing and timing a group of millisecond pulsars (MSPs) with high rotational stability enables the direct detection of gravitational waves (GWs). The GW signals can be identified from the spatial correlations encoded in the times-of-arrival of widely spaced pulsar-pairs. The Chinese Pulsar Timing Array (CPTA) is a collaboration aiming at the direct GW detection with observations carried out using Chinese radio telescopes. This short article serves as a `table of contents' for a forthcoming series of papers related to the CPTA Data Release 1 (CPTA DR1) which uses observations from the Five-hundred-meter Aperture Spherical radio Telescope (FAST). Here, after summarizing the time span and accuracy of CPTA DR1, we report the key results of our statistical inference finding a correlated signal with amplitude $\log A_{\rm c}= -14.4 \,^{+1.0}_{-2.8}$ for spectral index in the range of $α\in [-1.8, 1.5]$ assuming a GW background (GWB) induced quadrupolar correlation. The search for the Hellings-Downs (HD) correlation curve is also presented, where some evidence for the HD correlation has been found that a 4.6-$σ$ statistical significance is achieved using the discrete frequency method around the frequency of 14 nHz. We expect that the future International Pulsar Timing Array data analysis and the next CPTA data release will be more sensitive to the nHz GWB, which could verify the current results.

Graduate Record Examination Scores as Predictors of First Time Success on the National Certification Examination in a Midwest Nurse Anesthesia Program

subject: higher education

description: Purpose: The purpose of this scholarly project was to determine if GRE scores (verbal reasoning, quantitative reasoning, and analytical writing) predict first-time pass rate on the NCE. This project also investigated the correlation between first-time pass rate on the NCE and the individual covariates of age at program matriculation, sex, race, number of years as an RN, number of years as an ICU RN, entry-to-practice nursing GPA, and nurse anesthesia program GPA. Methods: A retrospective compilation of secondary data was assembled for 114 master’s degree students. Using SPSS® software, bivariate data analysis was performed using 10 independent variables and the dependent variable NCE result (pass/fail). Due to the high first attempt pass rate among the study population (87.7%), a second dependent variable, NCE total score, was also utilized. Multivariate analysis using nine of the 10 independent variables was completed for both NCE result (pass/fail) and NCE total score. Results: No statistically significant relationship between GRE scores and first attempt NCE pass rate was found. A positive but weak correlation existed between GRE scores and NCE total score, and a slight significance was noted with both GRE quantitative score (positive correlation) and GRE analytical score (negative correlation) in the multivariate linear regression model. Age at program matriculation, number of years as an ICU RN, and nurse anesthesia program GPA were statistically significant using both first attempt NCE result and NCE total score. Younger students with less ICU experience were more likely to pass the NCE on first attempt and scored higher on the NCE. Nurse anesthesia program GPA was positively correlated with both NCE result and NCE total score. Conclusion: This scholarly project supports removal of the GRE as an admission requirement in the investigator’s nurse anesthesia program, thus removing possible financial and motivational admission barriers which may allow for a more diverse, holistic admission process. Removal will likely expand the applicant pool since many other nurse anesthesia programs no longer require the GRE. Future studies may consider use of cumulative science GPA and the type of ICU in which the student has worked prior to matriculation as predictor variables.

description: Robust heteroclinic cycles are known to change stability in resonance bifurcations, which occur when an algebraic condition on the eigenvalues of the system is satisfied and which typically result in the creation or destruction of a long-period periodic orbit. Resonance bifurcations for heteroclinic networks are more complicated because different subcycles in the network can undergo resonance at different parameter values, but have, until now, not been systematically studied. In this article we present the first investigation of resonance bifurcations in heteroclinic networks. Specifically, we study two heteroclinic networks in $\R^4$ and consider the dynamics that occurs as various subcycles in each network change stability. The two cases are distinguished by whether or not one of the equilibria in the network has real or complex contracting eigenvalues. We construct two-dimensional Poincare return maps and use these to investigate the dynamics of trajectories near the network. At least one equilibrium solution in each network has a two-dimensional unstable manifold, and we use the technique developed in [18] to keep track of all trajectories within these manifolds. In the case with real eigenvalues, we show that the asymptotically stable network loses stability first when one of two distinguished cycles in the network goes through resonance and two or six periodic orbits appear. In the complex case, we show that an infinite number of stable and unstable periodic orbits are created at resonance, and these may coexist with a chaotic attractor. There is a further resonance, for which the eigenvalue combination is a property of the entire network, after which the periodic orbits which originated from the individual resonances may interact. We illustrate some of our results with a numerical example.

description: We present a multi-facility study of the optical spectrum of the extragalactic globular cluster RZ2109, which hosts a bright black hole X-ray source. The optical spectrum of RZ2109 shows strong and very broad [O III]λλ4959,5007 emission in addition to the stellar absorption lines typical of a globular cluster. We use observations over an extended period of time to constrain the variability of these [O III] emission lines. We find that the equivalent width of the lines is similar in all of the datasets; the change in L[O III]λ5007 is \ltsim 10% between the first and last observations, which were separated by 467 days. The velocity profile of the line also shows no significant variability over this interval. Using a simple geometric model we demonstrate that the observed [O III]λ5007 line velocity structure can be described by a two component model with most of the flux contributed by a bipolar conical outflow of about 1,600 km/s, and the remainder from a Gaussian component with a FWHM of several hundred km/s.

Publisher: name: International Journal of Dream Research
Year: 2020

description: The goal of this research is to investigate whether imagining that the space of lucid dreams is the actual physical leads to better perception vividness. We had 152 volunteers complete a task during a lucid dream in which they needed to imagine that the space around them was real. Then they needed to check how the quality of perceptions changed. Of the participants, 51% achieved increased vividness; for 23% of them, their perceptions exceeded the vividness of wakefulness. The results of this research might lead to a better understanding of the nature of subjective perceptions in lucid dreams, which, in turn, might help in researching this phenomenon and its application.

description: We have detected the CO(6-5), CO(7-6), and [CI] 370 micron lines from the nuclear region of NGC 891 with our submillimeter grating spectrometer ZEUS on the CSO. These lines provide constraints on photodissociation region (PDR) and shock models that have been invoked to explain the H_2 S(0), S(1), and S(2) lines observed with Spitzer. We analyze our data together with the H_2 lines, CO(3-2), and IR continuum from the literature using a combined PDR/shock model. We find that the mid-J CO originates almost entirely from shock-excited warm molecular gas; contributions from PDRs are negligible. Also, almost all the H_2 S(2) and half of the S(1) line is predicted to emerge from shocks. Shocks with a pre-shock density of 2x10^4 cm^-3 and velocities of 10 km/s and 20 km/s for C-shocks and J-shocks, respectively, provide the best fit. In contrast, the [CI] line emission arises exclusively from the PDR component, which is best parameterized by a density of 3.2x10^3 cm^-3 and a FUV field of G_o = 100 for both PDR/shock-type combinations. Our mid-J CO observations show that turbulence is a very important heating source in molecular clouds, even in normal quiescent galaxies. The most likely energy sources for the shocks are supernovae or outflows from YSOs. The energetics of these shock sources favor C-shock excitation of the lines.

This paper presents results from an investigation into using a fuzzy DGP representation within the XCSF Learning Classifier System. In particular, asynchronous Fuzzy Logic Networks are used to represent the traditional condition-action production system rules. It is shown possible to use self-adaptive, open-ended evolution to design an ensemble of such fuzzy dynamical systems within XCSF to solve several well-known continuous-valued test problems.

description: Social interactions, especially with the romantic partner, are a very important part of waking life and – in line with the continuity hypothesis of dreaming – also play an important role in dreams. In total, 1695 persons (960 women, 735 men; mean age: 53.84 ± 13.99 yrs.) completed an online survey that included questions about estimating retrospectively the frequency of partner and ex-partner(s) dreams and questions about their relationship status. These estimates indicate that partner dreams are not only common in persons with stable partnership (24%) but also in singles (16%). Partnership quality was the strongest predictor of the emotional tone of partner dreams. Ex-partner dreams were less positive than partner dreams and quite frequent – even years after separation. The next step would be to collect partner and ex-partner dream reports and study the interaction between partnership and partner dreams in a longitudinal design.

description: Background: In Australia, there is a lack of accurate data on midwifery workforce staffing and skill mix, which in turn hinders workforce policy and planning. Aim: To describe the current staffing levels of the midwifery workforce in Victoria, Australia, explore workforce challenges and assess the impact of COVID-19 pandemic on staffing. Design: Cross-sectional. Methods: Midwifery managers in all public and private maternity services in Victoria, Australia were invited to complete a survey exploring midwifery staffing numbers and adequacy. Topics explored included midwifery turnover, recruitment, and skill mix. Descriptive statistics were used. Findings: The survey was open March to October 2021, and 56 % (38/68) of managers responded. Of these, 76 % reported inadequate midwifery staff levels, with deficits ranging from one to 19 estimated Full-Time Equivalent (EFT) midwives, with a combined total deficit of 135 EFT. In the 12 months prior to the survey, 73 % of services had found it difficult to recruit midwives, with increased difficulty during the COVID-19 pandemic. Managers were concerned about retaining and recruiting ‘experienced’ midwives due to an ageing workforce and high turnover due to work/life imbalance and job dissatisfaction. These issues have led to a predominantly early career midwifery workforce and created concern about skill mix. Conclusion: Victorian maternity services have a midwifery workforce shortage and are experiencing significant skill mix issues. The pandemic has exacerbated these considerable gaps in the workforce. Urgent implementation of retention and recruitment schemes are needed, along with strategies to improve the working conditions for the current workforce.

description: The present work deals with an improved back-propagation algorithm based on Gauss-Newton numerical optimization method for fast convergence. The steepest descent method is used for the back-propagation. The algorithm is tested using various datasets and compared with the steepest descent back-propagation algorithm. In the system, optimization is carried out using multilayer neural network. The efficacy of the proposed method is observed during the training period as it converges quickly for the dataset used in test. The requirement of memory for computing the steps of algorithm is also analyzed.

description: The autocorrelation function of pattern fluctuation is used to study soft-mode turbulence (SMT), a spatiotemporal chaos observed in homeotropic nematics. We show that relaxation near the electroconvection threshold deviates from the exponential. To describe this relaxation, we propose a compressed exponential appearing in dynamics of glass forming liquids. Our findings suggest that coherent motion contributes to SMT dynamics. We also confirmed that characteristic time is inversely proportional to electroconvection's control parameter.

description: The noise in millisecond pulsar (MSP) timing data can include contributions from observing instruments, the interstellar medium, the solar wind, solar system ephemeris errors, and the pulsars themselves. The noise environment must be accurately characterized in order to form the null hypothesis from which signal models can be compared, including the signature induced by nanohertz-frequency gravitational waves (GWs). Here we describe the noise models developed for each of the MSPs in the Parkes Pulsar Timing Array (PPTA) third data release, which have been used as the basis of a search for the isotropic stochastic GW background. We model pulsar spin noise, dispersion measure variations, scattering variations, events in the pulsar magnetospheres, solar wind variability, and instrumental effects. We also search for new timing model parameters and detected Shapiro delays in PSR~J0614$-$3329 and PSR~J1902$-$5105. The noise and timing models are validated by testing the normalized and whitened timing residuals for Gaussianity and residual correlations with time. We demonstrate that the choice of noise models significantly affects the inferred properties of a common-spectrum process. Using our detailed models, the recovered common-spectrum noise in the PPTA is consistent with a power law with a spectral index of $γ=13/3$, the value predicted for a stochastic GW background from a population of supermassive black hole binaries driven solely by GW emission.

description: A subset of 51 Hipparcos astrometric binaries among FG dwarfs within 67pc has been surveyed with the NICI adaptive optics system at Gemini-S, directly resolving for the first time 17 sub-arcsecond companions and 7 wider ones. Using these data together with published speckle interferometry of 57 stars, we compare the statistics of resolved astrometric companions with those of a simulated binary population. The fraction of resolved companions is slightly lower than expected from binary statistics. About 10% of astrometric companions could be "dark" (white dwarfs and close pairs of late M-dwarfs). To our surprise, several binaries are found with companions too wide to explain the acceleration. Re-analysis of selected intermediate astrometric data shows that some acceleration solutions in the original Hipparcos catalog are spurious.

Der Stuttgarter Psalter - (K)eine Quelle für die Archäologie des Frühmittelalters?

description: Der Stuttgarter Psalter – (k)eine Quelle für die Archäologie des Frühmittelalters? Die zahlreichen Illustrationen des angeblich zwischen 820 und 830 im Skriptorium des Klosters Saint-Germain-des-Prés entstandenen sogenannten Stuttgarter Psalters werden in der deutschsprachigen Literatur zur Archäologie der Merowinger- und Karolingerzeit gerne für historische Interpretationen, z. B. für die Bekleidung, genutzt. Die Darstellungen wirken sehr realistisch, sodass oft der Eindruck entsteht, ein Gegenstand, Kleidungsstück oder die Tragweise eines Schwertes ließe sich im archäologischen Fundgut identifizieren. In einigen Fällen, wie bei Schildbuckeln oder Scheibenfibeln, ist dies der Fall – allerdings sind vergleichbare Formen oft schon vor der Entstehungszeit des Buches durch Funde nachgewiesen und können deshalb nicht als Abbild der Sachkultur der ersten Hälfte des 9. Jahrhunderts angesehen werden. Dieser Quellenwert für die Karolingerzeit wird von der kunsthistorischen Forschung zum Psalter nicht aufgegriffen; stattdessen werden die mediterranen Vorbilder, die bis in die Spätantike zurückreichen, betont. Die Auswertung von verschiedenen Illustrationen ergab, dass nur in seltenen Fällen die abgebildeten Dinge tatsächlich als typisch für die Karolingerzeit gelten können. Da diese Datierung auf Bodenfunden beruht, bedeutet dies, dass man mit der Archäologie den Wahrheitsgehalt einer Darstellung nachweisen kann, aber nicht umgekehrt.

The angular momentum transport by standard MRI in quasi-Kepler cylindric Taylor-Couette flows

description: The instability of a quasi-Kepler flow in dissipative Taylor-Couette systems under the presence of an homogeneous axial magnetic field is considered with focus to the excitation of nonaxisymmetric modes and the resulting angular momentum transport. The excitation of nonaxisymmetric modes requires higher rotation rates than the excitation of the axisymmetric mode and this the more the higher the azimuthal mode number m. We find that the weak-field branch in the instability map of the nonaxisymmetric modes has always a positive slope (in opposition to the axisymmetric modes) so that for given magnetic field the modes with m>0 always have an upper limit of the supercritical Reynolds number. In order to excite a nonaxisymmetric mode at 1 AU in a Kepler disk a minimum field strength of about 1 Gauss is necessary. For weaker magnetic field the nonaxisymmetric modes decay. The angular momentum transport of the nonaxisymmetric modes is always positive and depends linearly on the Lundquist number of the background field. The molecular viscosity and the basic rotation rate do not influence the related α-parameter. We did not find any indication that the MRI decays for small magnetic Prandtl number as found by use of shearing-box codes. At 1 AU in a Kepler disk and a field strength of about 1 Gauss the α proves to be (only) of order 0.005.
Hyperbolic metamaterial interfaces: Hawking radiation from Rindler horizons and the "end of time"

description: Extraordinary rays in a hyperbolic metamaterial behave as particle world lines in a three dimensional (2+1) Minkowski spacetime. We analyze electromagnetic field behavior at the boundaries of this effective spacetime depending on the boundary orientation. If the boundary is perpendicular to the space-like direction in the metamaterial, an effective Rindler horizon may be observed which produces Hawking radiation. On the other hand, if the boundary is perpendicular to the time-like direction an unusual physics situation is created, which can be called "the end of time". It appears that in the lossless approximation electromagnetic field diverges at the interface in both situations. Experimental observations of the "end of time" using plasmonic metamaterials confirm this conclusion.

On the collective curvature radiation

description: The paper deals with the one possible mechanism of the pulsar radio emission, i.e., with the collective curvature radiation of the relativistic particle stream moving along the curved magnetospheric magnetic field lines. It is shown that the electromagnetic wave containing one cylindrical harmonic exp{isϕ} can not be radiated by the curvature radiation mechanism, that corresponds to radiation of a charged particle moving along curved magnetic field lines. The point is that the particle in vacuum radiates the triplex of harmonics (s, s \pm 1), so for the collective curvature radiation the wave polarization is very important and cannot be fixed a priori. For this reason the polarization of real unstable waves must be determined directly from the solution of wave equations for the media. Its electromagnetic properties should be described by the dielectric permittivity tensor \^ε(ω,k,r), that contains the information on the reaction on all possible types of radiation.
