description: We investigate dynamical and radiative properties of arc-shaped gas clouds falling onto a stellar mass black hole based on the three-dimensional general relativistic radiation-magnetohydrodynamics (3D-GRRMHD) simulation data. Assuming that the gas clouds radiate due mainly to the free-free emission and/or optically thick, inverse Compton scattering, we calculate how the emissivity distributions develop with time. We find that (1) gas clouds, each of which has a ring-like or arc shape, are intermittently formed, and that (2) they slowly fall to the black hole, keeping nearly the Keplerian orbital velocity. These features support the dynamical properties of the gas clouds assumed in the spin measurement method proposed by Moriyama & Mineshige 2015, but the radius of the inner edge of the accretion disk is larger than that of the marginally stable orbit (ISCO). Next, we examine how each gas cloud is observed by a distant observer by calculating the photon trajectories in the black hole space-time. The luminosity of the accretion flow exhibits significant time variations on different timescales, reflecting the time evolution of the gas density distributions. The relatively slow variations on the time durations of 0.08-0.10 sec is due to the formation and fall of gas clouds, while quasi-periodic flux peaks with short time intervals (0.01 sec) are due to the quasi-periodic enhancement of light from the non-axisymmetric arc-shaped clouds through the beaming effect. This may account for the high-frequency quasi-periodic oscillations (HF QPOs) observed in black hole binaries. The observational implications and future issues are briefly discussed.

description: Clathrate hydrates have characteristic properties that render them attractive for a number of industrial applications. Of particular interest are the following two cases: (i) the incorporation of large amounts of gas molecules into the solid structure has resulted in considering hydrates as possible material for the storage/transportation of energy or environmental gases, and (ii) the selective incorporation of guest molecules into the solid structure has resulted in considering hydrates for gas-mixture separations. For the proper design of such industrial applications, it is essential to know accurately a number of thermodynamic, structural and transport properties. Such properties can either be measured experimentally or calculated at different scales that span the molecular scale-up to the continuum scale. By using clathrate hydrates as a particular case study, we demonstrate that performing studies at multiple length scales can be utilised in order to obtain properties that are essential to process design.

description: We describe the discovery circumstances and photometric properties of 2000 EB173, now one of the brightest trans-Neptunian objects (TNOs) with opposition magnitude m_R=18.9 and also one of the largest Plutinos, found with the drift-scanning camera of the QUEST Collaboration, attached to the 1-m Schmidt telescope of the National Observatory of Venezuela. We measure B-V = 0.99 +/- 0.14 and V-R = 0.57 +/- 0.05, a red color observed for many fainter TNOs. At our magnitude limit m_R = 20.1 +/- 0.20, our single detection reveals a sky density of 0.015 (+0.034, -0.012) TNOs per deg^2 (the error bars are 68% confidence limits), consistent with fainter surveys showing a cumulative number proportional to 10^0.5m_R. Assuming an inclination distribution of TNOs with FWHM exceeding 30 deg, it is likely that one hundred to several hundred objects brighter than m_R=20.1 remain to be discovered.

description: Microneedles (MNs) enhance drug delivery by painlessly penetrating the stratum corneum, with hardness being crucial for safe insertion. While human/animal skins and synthetic materials are used to test MNs, their variability affects results. Finite element methods (FEM) simulate insertion, but skin model complexity and software limitations cause inconsistencies. This study employs FEM to compare MN performance across skun models under uniform conditions. Results reveal small volume change differences during insertion and rank penetration ease for human/animal models, aiding skin model selection and species-specific MN design optimization.

description: Out of equilibrium phases of matter exhibiting order in individual eigenstates, such as many-body localised spin glasses and discrete time crystals, can be characterised by inherently dynamical quantities such as spatiotemporal correlation functions. In this work, we introduce dynamical potentials which act as generating functions for such correlations and capture eigenstate phases and order. These potentials show formal similarities to their equilibrium counterparts, namely thermodynamic potentials. We provide three representative examples: a disordered, many-body localised XXZ chain showing many-body localisation, a disordered Ising chain exhibiting spin-glass order and its periodically-driven cousin exhibiting time-crystalline order.

description: Virtual reality (VR) has been repeatedly applied for personal development purposes, ranging from learning and training (cognitive outcomes), to psychological therapies (emotional outcomes), to physical rehabilitation (physical outcomes). Several factors lead to a successful VR intervention, most notably the hardware and software. In the current article, a meta-analysis is performed to test the effect of specialized input hardware (e.g motion sensors, floor pads, etc.), advanced output hardware (i.e., head-mounted displays, surround-screen displays, etc.), and game elements (i.e., score, competition, etc.) across and within the three noted applications of VR intervention. When analyzing the overall effects, only game elements had a significant impact on outcomes. When analyzing specific applications, input hardware did not have a notable impact on outcomes for any application; output hardware had a notable impact on cognitive and emotional outcomes but not physical; and game elements had a notable impact on cognitive outcomes but not emotional or physical. From these results, the current article provides direct suggestions for future research and practice. Particularly, certain mediating mechanisms are suggested to explain the impact of output hardware and game elements on VR intervention outcomes, sparking possible new directions for research and practice.
Time dependent local potential in a Tomonaga-Luttinger liquid

description: We study the energy deposition in a one dimensional interacting quantum system with a point like potential modulated in amplitude. The point like potential at position $x=0$ has a constant part and a small oscillation in time with a frequency $ω$. We use bosonization, renormalization group and linear response theory to calculate the corresponding energy deposition. It exhibits a power law behavior as a function of the frequency that reflects the Tomonaga-Luttinger liquid (TLL) nature of the system. Depending on the interactions in the system, characterized by the TLL parameter $K$ of the system, a crossover between week and strong coupling for the backscattering due to the potential is possible. We compute the frequency scale $ω_\ast$, at which such crossover exists. We find that the energy deposition due to the backscattering shows different exponent for $K>1$ and $K<1$. We discuss possible experimental consequences, in the context of cold atomic gases, of our theoretical results.

description: In this paper, we investigate 2727 galaxies observed by MaNGA as of June 2016 to develop spatially resolved techniques for identifying signatures of active galactic nuclei (AGN). We identify 303 AGN candidates. The additional spatial dimension imposes challenges in identifying AGN due to contamination from diffuse ionized gas, extra-planar gas and photoionization by hot stars. We show that the combination of spatially-resolved line diagnostic diagrams and additional cuts on H$α$ surface brighness and H$α$ equivalent width can distinguish between AGN-like signatures and high-metallicity galaxies with LINER-like spectra. Low mass galaxies with high specific star formation rates are particularly difficult to diagnose and routinely show diagnostic line ratios outside of the standard star-formation locus. We develop a new diagnostic -- the distance from the standard diagnostic line in the line-ratios space -- to evaluate the significance of the deviation from the star-formation locus. We find 173 galaxies that would not have been selected as AGN candidates based on single-fibre spectral measurements but exhibit photoionization signatures suggestive of AGN activity in the MaNGA resolved observations, underscoring the power of large integral field unit (IFU) surveys. A complete census of these new AGN candidates is necessary to understand their nature and probe the complex co-evolution of supermassive black holes and their hosts.

NURSING AND MIDWIFERY STUDENTS’ LENS: CONNECTING THEORETICAL KNOWLEDGE WITH CLINICAL PRACTICE: AN INTERPRETATIVE PHENOMENOLOGICAL STUDY
Creators: name: Sankar, Mynesha
Publisher: name: London South Bank University
Year: 2024

description: Aim: To explore and critically analyse the strategies employed by final-year BSc pre-registration nursing and midwifery students at an inner London university to connect theoretical knowledge with clinical practice, to promote their learning and professional development. Background: Navigating the theory-practice gap has been a significant challenge for nursing and midwifery students. While there are many perspectives from academics and clinicians, how theoretical knowledge is connected with clinical practice is rarely discussed and studied from the students’ perspectives. Design: Interpretative phenomenological analysis was used to understand nursing and midwifery students' experiences in connecting theoretical knowledge with clinical practice. Rather than attempting to establish objective truth, this thesis focused on participants’ subjective experiences. Method: This study employed a qualitative research design. The data was obtained using semi-structured interviews and analysed using an inductive approach. The study population included (n=12) pre-registration nursing and midwifery students enrolled on a Bachelor of Science programs. Findings: Four themes emerged (1) Complexity of embodied knowledge; (2) Sensing the meaning of personal and professional learning; (3) Demographic attributes and self-understanding; (4) Sense-making of COVID-19. Conclusion: The process by which pre-registration nursing and midwifery students connect theoretical knowledge with clinical practice is complex and multifaceted. It intersects with other factors and cannot be understood in isolation. This interconnectedness necessitates a thorough examination of all the variables involved.
Is there another coincidence problem at the reionization epoch?

description: The cosmological coincidences between the matter and radiation energy densities at recombination as well as between the densities of matter and the cosmological constant at present time are well known. We point out that moreover the third intersection between the energy densities of radiation and the cosmological constant coincides with the reionization epoch. To quantify the statistical relevance of this concurrence, we compute the Bayes factor between the concordance cosmology with free Thomson scattering optical depth and a model for which this parameter is inferred from imposing a match between the time of density equality and the epoch of reionization. This is to characterize the potential explanatory gain if one were to find a parameter-free physical connection. We find a very strong preference for such a concurrence on the Jeffreys scale from current cosmological observations. We furthermore discuss the effect of choice of priors, changes in reionization history, and free sum of neutrino masses. We also estimate the impact of adding intermediate polarization data from the Planck High Frequency Instrument and prospects for future 21 cm surveys. In the first case, preference for the correlation remains substantial, whereas future data may give results more decisive in pro or substantial in contra. Finally, we provide a discussion on different interpretations of these findings. In particular, we show how a connection between the star-formation history and the cosmological background dynamics can give rise to this concurrence.

description: ‘BRCAness’ is a term used to describe cancer cells that behave similarly to tumors with BRCA1 or BRCA2 mutations. The BRCAness phenotype is associated with hypersensitivity to chemotherapy agents including PARP inhibitors, which are a promising class of recently-licensed anti-cancer treatments. This hypersensitivity arises because of a deficiency in the homologous recombination (HR) pathway for DNA double-strand break repair. To gain further insight into how genetic modifiers of HR contribute to the BRCAness phenotype, we created a new mouse model of BRCAness by generating mice that are deficient in BLM helicase and the Exo1 exonuclease, which are involved in the early stages of HR. We find that cells lacking BLM and Exo1 exhibit a BRCAness phenotype, with diminished HR, and hypersensitivity to PARP inhibitors. We further tested how 53BP1, an important regulator of HR, affects repair efficiency in our BRCAness model. We find that deletion of 53BP1 can relieve several of the repair deficiencies observed in cells lacking BLM and Exo1, just as it does in cells lacking BRCA1. These results substantiate the importance of BRCAness as a concept for classification of cancer cases, and further clarify the role of 53BP1 in regulation of DNA repair pathway choice in mammalian cells.

description: Markov Chain Monte Carlo based Bayesian data analysis has now become the method of choice for analyzing and interpreting data in almost all disciplines of science. In astronomy, over the last decade, we have also seen a steady increase in the number of papers that employ Monte Carlo based Bayesian analysis. New, efficient Monte Carlo based methods are continuously being developed and explored. In this review, we first explain the basics of Bayesian theory and discuss how to set up data analysis problems within this framework. Next, we provide an overview of various Monte Carlo based methods for performing Bayesian data analysis. Finally, we discuss advanced ideas that enable us to tackle complex problems and thus hold great promise for the future. We also distribute downloadable computer software (available at https://github.com/sanjibs/bmcmc/ ) that implements some of the algorithms and examples discussed here.

description: The short-spacing problem describes the inherent inability of radio-interferometric arrays to measure the integrated flux and structure of diffuse emission associated with extended sources. New interferometric arrays, such as SKA, require solutions to efficiently combine interferometer and single-dish data. We present a new and open source approach for merging single-dish and cleaned interferometric data sets requiring a minimum of data manipulation while offering a rigid flux determination and full high angular resolution. Our approach combines single-dish and cleaned interferometric data in the image domain. This approach is tested for both Galactic and extragalactic HI data sets. Furthermore, a quantitative comparison of our results to commonly used methods is provided. Additionally, for the interferometric data sets of NGC4214 and NGC5055, we study the impact of different imaging parameters as well as their influence on the combination for NGC4214. The approach does not require the raw data (visibilities) or any additional special information such as antenna patterns. This is advantageous especially in the light of upcoming radio surveys with heterogeneous antenna designs.

description: We report on the first multi-color precision light curve of the bright Wolf-Rayet binary $γ^2$ Velorum, obtained over six months with the nanosatellites in the BRITE- Constellation fleet. In parallel, we obtained 488 high-resolution optical spectra of the system. In this first report on the datasets, we revise the spectroscopic orbit and report on the bulk properties of the colliding winds. We find a dependence of both the light curve and excess emission properties that scales with the inverse of the binary separation. When analyzing the spectroscopic properties in combination with the photometry, we find that the phase dependence is caused only by excess emission in the lines, and not from a changing continuum. We also detect a narrow, high-velocity absorption component from the He I $λ$5876 transition, which appears twice in the orbit. We calculate smoothed-particle hydrodynamical simulations of the colliding winds and can accurately associate the absorption from He I to the leading and trailing arms of the wind shock cone passing tangentially through our line of sight. The simulations also explain the general strength and kinematics of the emission excess observed in wind lines such as C III $λ$5696 of the system. These results represent the first in a series of investigations into the winds and properties of $γ^2$ Velorum through multi-technique and multi-wavelength observational campaigns.

description: We presents results from a spectroscopic survey of $z\sim5$ quasars in the CFHT Legacy Survey (CFHTLS). Using both optical color selection and a likelihood method we select 97 candidates over an area of 105 deg$^2$ to a limit of $i_{\rm AB} < 23.2$, and 7 candidates in the range $23.2 < i_{\rm AB} < 23.7$ over an area of 18.5 deg$^2$. Spectroscopic observations for 43 candidates were obtained with Gemini, MMT, and LBT, of which 37 are $z>4$ quasars. This sample extends measurements of the quasar luminosity function $\sim$1.5 mag fainter than our previous work in SDSS Stripe 82. The resulting luminosity function is in good agreement with our previous results, and suggests that the faint end slope is not steep. We perform a detailed examination of our survey completeness, particularly the impact of the Ly$α$ emission assumed in our quasar spectral models, and find hints that the observed Ly$α$ emission from faint $z\sim5$ quasars is weaker than for $z\sim3$ quasars at a similar luminosity. Our results strongly disfavor a significant contribution of faint quasars to the hydrogen-ionizing background at $z=5$.

description: Our local environment at $r<10$ Mpc expands linearly and smoothly, as if ruled by a uniform matter distribution, while observations show the very clumpy local universe. This is a long standing enigma in cosmology. We argue that the recently discovered vacuum or quintessence (dark energy (DE) component with the equation of state $p_Q = w ρ_Q c^2$, $w \in [-1,0)$) from observations of the high-redshift universe may also manifest itself in the properties of the very local Hubble flow. We introduce the concept of the critical distance $r_Q$ where the repulsive force of dark energy starts to dominate over the gravity of a mass concentration. For the Local Group $r_Q$ is about 1.5 Mpc. Intriguingly, at the same distance 1.5 Mpc the linear and very "cold" Hubble flow emerges, with about the global Hubble constant. We also consider the critical epoch $t_Q$, when the DE antigravity began to dominate over the local matter gravity for a galaxy which at the present epoch is in the local DE dominated region. Our main result is that the homogeneous dark energy component, revealed by SNIa observations, resolves the old confrontation between the local Hubble flow and local highly non-uniform, fractal matter distribution. It explains why the Hubble law starts on the outskirts of the Local Group, with the same Hubble constant as globally and with a remarkably small velocity dispersion.

description: Fin dalle origini della letteratura italiana l’arte del racconto si nutre di forme narrative eterogenee che hanno in comune la brevitascome criterio organizzativo dei contenuti. Il saggio affronta la tradizione della narratio brevis medievale e rinascimentale a partire dalle suggestioni narrative contemporanee e dal dibattito critico novecentesco sulle forme brevi. Nell’era dello storytelling è, forse, utile fare il punto sulla ricchezza e sull’attualità della più antica tradizione novellistica e delle sue molteplici trasformazioni. Since the origins of Italian literature, the art of storytelling puts together heterogeneous narrative forms that have in common the brevitasas an organizational criterion of the contents. The essay deals with the tradition of medieval and Renaissance narratio brevis starting from contemporary narrative suggestions and the twentieth-century critical debate on short forms. In the era of storytelling it is perhaps useful to remember the richness and topicality of the most ancient short story tradition and its many transformations.

description: It is shown that an alternative supersymmetric version of the Liouville equation extracted from D=3 Green-Schwarz superstring equations naturally arises as a super-Toda model obtained from a properly constrained supersymmetric WZNW theory based on the $sl(2, R)$ algebra. Hamiltonian reduction is performed by imposing a nonlinear superfield constraint which turns out to be a mixture of a first- and second-class constraint on supercurrent components. Supersymmetry of the model is realized nonlinearly and is spontaneously broken. The set of independent current fields which survive the Hamiltonian reduction contains (in the holomorphic sector) one bosonic current of spin 2 (the stress--tensor of the spin 0 Liouville mode) and two fermionic fields of spin ${3/2}$ and $-1/2$. The $n=1$ superconformal system thus obtained is of the same kind as one describing noncritical fermionic strings in a universal string theory. The generalization of this procedure allows one to produce from any bosonic Lie algebra super--Toda models and associated super-W algebras together with their nonstandard realizations.

description: It is proposed to use four atomic optical energy levels as a two qubit quantum register. A single Pr3+ atom in a monocrystal LaF3 subjected to resonant laser irradiation is used as an example to illustrate the implementation of the universal set of quantum gates. The equilibrium state of this physical system is a desirable input state for quantum computation and therefore there is no need for its special preparation procedure.

description: Mutations in the splicing factor pre-messenger RNA processing factor 31 (PRPF31) gene cause autosomal dominant retinitis pigmentosa 11 (RP11) through a haplo-insufficiency mechanism. We describe the phenotype and progression of microperimetry and autofluorescence endpoints in an Indigenous Australian RP11 family. Ophthalmic examination, optical coherence tomography, fundus autofluorescence and microperimetry were performed at baseline and every 6–12 months. Baseline and annual change in best-corrected visual acuity (BCVA), microperimetry mean sensitivity (MS) and number of scotoma loci, residual ellipsoid zone (EZ) span and hyperautofluorescent ring (HAR) area were reported. Next-generation and Sanger sequencing were performed in available members. 12 affected members from three generations were examined. Mean (SD, range) age at onset of symptoms was 11 (4.5, 4–19) years. MS declined steadily from the third decade and EZ span and HAR area declined rapidly during the second decade. Serial microperimetry showed negligible change in MS over 2–3 years. However, mean EZ span, near-infrared and short-wavelength HAR area reduction was 203 (6.4%) µm/year, 1.8 (8.7%) mm2/year and 1.1 (8.6%) mm2/year, respectively. Genetic testing was performed on 11 affected and 10 asymptomatic members and PRPF31 c.1205 C > A (p.Ser402Ter) mutation was detected in all affected and two asymptomatic members (non-penetrant carriers). Our findings suggest that in the studied cohort, the optimal window for therapeutic intervention is the second decade of life and residual EZ span and HAR area can be considered as efficacy outcome measures. Further studies on larger samples with different PRPF31 mutations and longer follow-up duration are recommended.
What is the Highest Plausible Redshift of Luminous Quasars?

description: The recent discoveries of luminous quasars at high redshifts imply that black holes more massive than a few billion solar masses have been assembled already when the universe was less than a billion years old. We show that the existence of these black holes is not surprising in popular hierarchical models of structure formation. For example, the black hole needed to power the quasar SDSS 1044-0125 at redshift z=5.8 can arise naturally from the growth of stellar mass seeds forming at z>10, when typical values are assumed for the radiative accretion efficiency and the bolometric accretion luminosity in Eddington units. Nevertheless, SDSS 1044-0125 yields a non-trivial constraint on a combination of these parameters. Extrapolating our model to future surveys, we derive the highest plausible redshift for quasars which are not lensed or beamed, as a function of their apparent magnitude. We find that at a limiting magnitude of K(AB)=20, quasar surveys can yield strong constraints on the growth of supermassive black holes out to z=10.

description: Wide-range C-reactive protein (wr-CRP) has been proposed as an economical alternative to high-sensitivity C-reactive protein (hs-CRP) for the evaluation of low-grade inflammation-associated cardiovascular risk (LGI-CVR). Concomitant values of serum hs-CRP and plasma wr-CRP ≤5 mg/L, and high-sensitivity cardiac troponin T (hs-cTnT), all assayed on Roche Diagnostics analyzers over a 1.8-year period, were extracted from a hospital laboratory database. Hs-CRP and wr-CRP values were compared (Bland–Altman method; Deming’s correlation), then separately classified into low (<1 mg/L), moderate (1–3 mg/L) and high (>3 mg/L) LGI-CVR ranges for agreement test (κ), assessed before and after Deming’s regression-based adjustment of wr-CRP (Adj-wr-CRP). Wr-CRP and hs-CRP values were strongly correlated, with linearity, whether below 5 mg/L (n = 744; τ = 0.933; p n = 283; τ = 0.823; p p
Rudiments of Dual Feynman Rules for Yang-Mills Monopoles in Loop Space

description: Dual Feynman rules for Dirac monopoles in Yang-Mills fields are obtained by the Wu-Yang (1976) criterion in which dynamics result as a consequence of the constraint defining the monopole as a topological obstruction in the field. The usual path-integral approach is adopted, but using loop space variables of the type introduced by Polyakov (1980). An anti-symmetric tensor potential $L_{μν}[ξ|s]$ appears as the Lagrange multiplier for the Wu-Yang constraint which has to be gauge-fixed because of the ``magnetic'' $\widetilde{U}$-symmetry of the theory. Two sets of ghosts are thus introduced, which subsequently integrate out and decouple. The generating functional is then calculated to order $g^0$ and expanded in a series in $\widetilde{g}$. It is shown to be expressible in terms of a local ``dual potential'' $\widetilde{A}_μ(x)$ found earlier, which has the same progagator and the same interaction vertex with the monopole field as those of the ordinary Yang-Mills potential $A_μ$ with a colour charge, indicating thus a certain degree of dual symmetry in the theory. For the abelian case the Feynman rules obtained here are the same as in QED to all orders in $g$, as expected by dual symmetry.

description: We study theoretically the concept of homogenization in optics using an ensemble of randomly distributed resonant stationary atoms with density $ρ$. The ensemble is dense enough for the usual condition for homogenization, viz. $ρλ^3 \gg 1$, to be reached. Introducing the coherent and incoherent scattered powers, we define two criteria to define the homogenization regime. We find that when the excitation field is tuned in a broad frequency range around the resonance, none of the criteria for homogenization is fulfilled, meaning that the condition $ρλ^3\gg 1$ is not sufficient to characterize the homogenized regime around the atomic resonance. We interpret these results as a consequence of the light-induced dipole-dipole interactions between the atoms, which implies a description of scattering in terms of collective modes rather than as a sequence of individual scattering events. Finally, we show that, although homogenization can never be reached for a dense ensemble of randomly positioned laser-cooled atoms around resonance, it becomes possible if one introduces spatial correlations in the positions of the atoms or non-radiative losses, such as would be the case for organic molecules or quantum dots coupled to a phonon bath.
