description: Repeat induced abortion is a significant public health problem in China. International knowledge about repeat induced abortion and its associated risk factors in Chinese women is scarce, and existing studies are hard to access for international scholars because most are published in Chinese. A systematic review was conducted to analyse the prevalence of repeat induced abortion among Chinese women and determine correlated risk factors. Seven electronic databases were systematically searched. Data on the prevalence of repeat induced abortion and related factors were extracted and pooled using a meta-analysis and narrative approach. Of 2458 articles retrieved from seven databases, 21 were included in the study. The overall pooled prevalence of repeat induced abortion was 43.1% (95% confidence interval 36.7%, 49.5%). Of 25 exposures extracted, 15 factors were significantly correlated with repeat induced abortion, comprising seven individual demographic factors (i.e., age, education, employment, migrant status, parity, unhealthy lifestyle habits and region of residence), four reproductive health- and contraception-related factors (i.e., age at sexual debut, history of sexual activity, contraceptive knowledge and having a regular sexual life) and four sexual partner-related factors (i.e., multiple sexual partners, age of sexual partner, educational level of sexual partner and cohabitation with sexual partner). The study findings highlight the problem of repeat induced abortion in China and suggest the need for government and civil society to increase efforts to reduce the alarming risks of repeat induced abortion in Chinese women and make them and their sexual partners more aware and protective of their sexual and reproductive health.

description: Purpose: Steroid hormones in hormonal contraceptives influence a variety of metabolic parameters. Mainly, ethinyloestradiol (EE) in combined hormonal contraceptives (CHC) is a potent inducer of hepatic coagulation factors, has an impact on cholesterol and triglyceride levels and glucose tolerance. Progestins in CHC modify the oestrogen effects in different ways, depending on their pharmacologic properties. The metabolic impact of progestin-only contraceptives is generally considered low. Methods: The influence of novel drospirenone (DRSP)-only pill (4 mg DRSP in 24/4 intake) on a variety of lipid-, carbohydrate- and bone metabolic parameters and on haemostatic variables including clotting factors and D-Dimer level was evaluated in comparison to 0.075 mg desogestrel (DSG) during a multicentric, prospective, double-blind, double-dummy clinical trial with 1190 participants over nine treatment cycles. Results: For both DRSP and DSG, there was a decrease in cholesterol (total, HDL, and LDL) and triglyceride levels. No relevant influence on glucose, insulin, and c-peptide levels or bone remodelling markers were detected in both treatment groups. Considering the coagulatory parameters, there was no impact on hemostasis. Conclusions: The results confirm the beneficial properties of the drospirenone-only pill. EudraCT Number: 2011-002396-42
Continuum reverberation mapping and a new lag-luminosity relationship for AGN
Creators: name: Netzer, Hagai
Publisher: name: arXiv
Year: 2021
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: High cadence, high quality observations of active galactic nuclei (AGN) clearly show continuum variations with lags, relative to the shortest observed variable UV continuum, that increase with wavelength ("lag spectra"). These have been attributed to the irradiation and heating of the central accretion disk by the central X-ray emitting corona. An alternative explanation, connecting the observed lag-spectra to line and continuum emission from gas in the broad line region (BLR), has also been proposed. In this paper I show the clear spectral signature of the time-dependent diffuse gas emission in the lag-spectrum of 6 AGN. I also show a new lag-luminosity relationship for 9 objects which is a scaled down version of the well known lag(H-beta)-L(5100A) relationship in AGN. The shape of the lag-spectrum, and its normalization, are entirely consisted with diffuse emission from radiation pressure supported clouds in a BLR with a covering factor of about 0.2. While some contributions to the continuum lag from the irradiated disk cannot be excluded, there is no need for this explanation.

description: The equilibrium points and their linear stability has been discussed in the generalized photogravitational Chermnykh's problem. The bigger primary is being considered as a source of radiation and small primary as an oblate spheroid. The effect of radiation pressure has been discussed numerically. The collinear points are linearly unstable and triangular points are stable in the sense of Lyapunov stability provided $μ< μ_{Routh}=0.0385201$. The effect of gravitational potential from the belt is also examined. The mathematical properties of this system are different from the classical restricted three body problem.

description: We consider a family of random walks killed at the boundary of the Weyl chamber of the dual of $\rm{Sp}(4)$, which in addition satisfies the following property: for any $n\geq 3$, there is in this family a walk associated with a reflection group of order $2n$. Moreover, the case $n=4$ corresponds to a process which appears naturally by studying quantum random walks on the dual of $\rm{Sp}(4)$. For all the processes belonging to this family, we find the exact asymptotic of the Green functions along all infinite paths of states as well as that of the absorption probabilities along the boundaries.

description: Similarity analysis is used to identify the control parameter $R_A$ for the subset of avalanching systems that can exhibit Self- Organized Criticality (SOC). This parameter expresses the ratio of driving to dissipation. The transition to SOC, when the number of excited degrees of freedom is maximal, is found to occur when $R_A \to 0$. This is in the opposite sense to (Kolmogorov) turbulence, thus identifying a deep distinction between turbulence and SOC and suggesting an observable property that could distinguish them. A corollary of this similarity analysis is that SOC phenomenology, that is, power law scaling of avalanches, can persist for finite $R_A$, with the same $R_A \to 0$ exponent, if the system supports a sufficiently large range of lengthscales; necessary for SOC to be a candidate for physical ($R_A$ finite) systems.

description: To assess and compare the risk of venous thromboembolism (VTE) and arterial thromboembolism (ATE) in NOMAC-E2 users with levonorgestrel-containing combined oral contraceptive (COCLNG) users. This large, prospective, observational active surveillance study used a non-inferiority design. New users of NOMAC-E2 and COCLNG were recruited in 12 countries in Australia, Europe, and Latin America. Women were followed up directly and self-reported outcomes of interest were validated via treating physicians. The main outcome of interest was VTE, specifically deep venous thrombosis of the lower extremities (DVT) and pulmonary embolism (PE). Secondary outcomes included all VTE and ATE. Data on confounders were captured and independent blinded adjudication assessed the classification of events. Incidence rates, crude (HRcrude), and adjusted (HRadj) hazard ratios were calculated. A total of 101,498 women (49,598 NOMAC-E2 users and 51,900 COCLNG users) were enrolled and followed for up to 2 years (144,901 WY of observation). NOMAC-E2 users had a higher mean age (31.0 ± 8.63 years) than COCLNG users (29.3 ± 8.53 years) but other baseline characteristics were similar between the cohorts. The main analysis comparing the risk of DVT of the lower extremities and PE in NOMAC-E2 users versus COCLNG users yielded an HRadj of 0.59 (95% CI, 0.25–1.35) (adjusted for age, BMI, family history of VTE, and current duration of use). The risk of all VTE and ATE was not higher in NOMAC-E2 users compared with COCLNG users. NOMAC-E2 use was not associated with a higher risk of VTE or ATE compared with COCLNG.

description: We consider nonlinear-mediating-field generalizations of the Wick-Cutkosky model. Using an iterative approach and eliminating the mediating field by means of the covariant Green function we arrive at a Lagrangian density containing many-point time-nonlocal interaction terms. In low-order approximations of $ϕ^3{+}ϕ^4$ theory we obtain the usual two-current interaction as well as a three-current interaction of a confining type. The same result is obtained without approximation for a version of the dipole model. The transition to the Hamiltonian formalism and subsequent canonical quantization is performed with time non-locality taken into account approximately. A relativistic three-particle wave equation is derived variationally by using a three-particle Fock space trial state. The non-relativistic limit of this equation is obtained and its properties are analyzed and discussed.

description: We study the second-moment correlation length and the reduced susceptibility of two ferromagnetic Ising models with zero-temperature ordering. By introducing a scaling variable motivated by high-temperature series expansions, we are able to scale data for the one-dimensional Ising ferromagnet rigorously over the entire temperature range. Analogous scaling expressions are then applied to the two-dimensional fully frustrated Villain model where excellent finite-size scaling over the entire temperature range is achieved. Thus we broaden the applicability of the extended scaling method to Ising systems having a zero-temperature critical point.

description: We discuss the treatment of intrinsic transverse momenta in high energy scattering processes. Within the field theoretical framework of QCD the process is described in terms of correlators containing quark and gluon fields. The correlators, parameterized in terms of distribution and fragmentation functions, contain matrix elements of nonlocal field configurations requiring a careful treatment to assure color gauge invariance. It leads to nontrivial gauge links connecting the parton fields. For the transverse momentum dependent correlators the gauge links give rise to time reversal odd phenomena, showing up as single spin and azimuthal asymmetries. The gauge links, arising from multi-gluon initial and final state interactions, depend on the color flow in the process, challenging universality.

description: Present day quantum field theory (QFT) is founded on canonical quantization, which has served quite well, but also has led to several issues. The free field describing a free particle (with no interaction term) can suddenly become nonrenormalizable the instant a suitable interaction term appears. For example, using canonical quantization, $φ^4_4$, has been deemed a ``free" theory with no difference from a truly free field [1], [2], [3]. Using the same model, affine quantization has led to a truly interacting theory [4]. This fact alone asserts that canonical and affine tools of quantization deserve to be open to their procedures together as a significant enlargement of QFT.

description: It is widely assumed that the dominant source of scattering in graphene is charged impurities in a substrate. We have tested this conjecture by studying graphene placed on various substrates and in high-k media. Unexpectedly, we have found no significant changes in carrier mobility either for different substrates or by using glycerol, ethanol and water as a top dielectric layer. This suggests that Coulomb impurities are not the scattering mechanism that limits the mean free path currently attainable for graphene on a substrate.

description: The laser ion source project at the IGISOL facility, Jyvaskyla, has motivated the development and construction of an rf sextupole ion beam guide (SPIG) to replace the original skimmer electrode. The SPIG has been tested both off-line and on-line in proton-induced fission, light-ion and heavy-ion induced fusion-evaporation reactions and, in each case, has been directly compared to the skimmer system. For both fission and light-ion induced fusion, the SPIG has improved the mass-separated ion yields by a factor of typically 4 to 8. Correspondingly, the transmission efficiency of both systems has been studied in simulations with and without space charge effects. The transport capacity of the SPIG has been experimentally determined to be 10^12 ions/s before space charge effects start to take effect. A direct comparison with the simulation has been made using data obtained via light-ion fusion evaporation. Both experiment and simulation show an encouraging agreement as a function of current extracted from the ion guide.

description: Public health nursing is the oldest branch of nursing in the world. The word nursing itself is derived from the Latin “nutrio,” meaning to nourish. Since the infant, child, young adolescent must have a nourishing diet, adequate care and supervision to reach strong, healthy, happy adulthood, we find that mothers were the first public health nurses. From this we might expect to find maternity or child welfare as the basis of preventative nursing. Instead, we find the old law of mutual aid asserting, and the foundation is laid on the visiting of the poor and sick poor. We are able now to trace the slow progress of public health nursing through the years, oftentimes almost completely submerged by ignorance and superstition up to the present-day programs.

description: Context. While most (if not all) Type I Galactic globular clusters (GGCs) are characterised by spreads in the abundances of light chemical elements (e.g. Li, N, O, Na, Mg, Al), it is not yet well established whether similar spreads may exist in s-process elements as well. Aims. We investigated the possible difference in Ba abundance between the primordial (1P) and polluted (2P) stars in the Galactic globular cluster (GGC) 47 Tuc (NGC 104). For this, we obtained homogeneous abundances of Fe, Na, and Ba in a sample of 261 red giant branch (RGB) stars which is the largest sample used for Na and Ba abundance analysis in any GGC so far. Methods. Abundances of Na and Ba were determined using archival GIRAFFE/VLT spectra and 1D non-local thermodynamic equilibrium (NLTE) abundance analysis methodology. Results. Contrary to the finding of Gratton et al. (2013), we did not detect any significant Ba-Na correlation or 2P-1P Ba abundance difference in the sample of 261 RGB stars in 47 Tuc. This corroborates the result of D'Orazi et al. (2010) who found no statistically significant Ba-Na correlation in 110 RGB stars in this GGC. The average barium-to-iron ratio obtained in the sample of 261 RGB stars, $\langle{\rm Ba/Fe}_{\rm 1D~NLTE}\rangle = -0.01\pm0.06$, agrees well with those determined in Galactic field stars at this metallicity and may therefore represent the abundance of primordial proto-cluster gas that has not been altered during the subsequent chemical evolution of the cluster.

description: In this article, the general solution of the tachyonic Klein-Gordon equation is obtained as a Fourier integral performed on a suitable path in the complex ω-plane. In particular, it is proved that under given boundary conditions this solution does not contain any superluminal components. On the basis of this result, we infer that all possible spacelike wave equations describe the dynamics of subluminal particles endowed with imaginary mass. This result is validated for the Chodos equation, used to describe the hypothetical superluminal behaviour of neutrino. In this specific framework it is proved that the wave packet propagates in spacetime with subluminal group velocities and that for enough small energies it behaves as a localized wave.

description: Electrical conductance through various nanocontacts between gold electrodes is studied by using the density functional theory, scalar-relativistic pseudopotentials, generalized gradient approximation for the exchange-correlation energy and the recursion-transfer-matrix method along with channel decomposition. The nanocontact is modeled with pyramidal fcc(100) tips and 1 to 5 gold atoms between the tips. Upon elongation of the contact by adding gold atoms between the tips, the conductance at Fermi energy E_F evolves from G ~ 3 G_0 to G ~ 1 G_0 (G_0 = 2e/h^2). Formation of a true one-atom point contact, with G ~ 1 G_0 and only one open channel, requires at least one atom with coordination number 2 in the wire. Tips that share a common vertex atom or tips with touching vertex atoms have three partially open conductance channels at E_F, and the symmetries of the channels are governed by the wave functions of the tips. The long 5-atom contact develops conductance oscillations and conductance gaps in the studied energy range -3 < E-E_F < 5 eV, which reflects oscillations in the local density of electron states in the 5-atom linear "gold molecule" between the electrodes, and a weak coupling of this "molecule" to the tips.

The fetal hydantoin syndrome : a mouse model
Creators: name: Finnell, Richard H.
Publisher: name: University of British Columbia
Year: 2010

description: The suspected teratogenicity of Diphenylhydantoin (DPH) in man is important, especially to the 0.3 to 0.5% of pregnant women who are epileptic and, therefore, candidates for anticonvulsant drug therapy. To separate the teratogenic effect of epilepsy from DPH treatment, an animal model closely approximating the human condition was developed to meet the following criteria: (i) the test animal must have spontaneous seizures (ii) the seizures must be controlled or eliminated by DPH treatment (iii) the drug must be administered orally (iv) serum DPH levels must fall within the optimal human therapeutic range between 5 and 20 micrograms per ml serum (v) treatment must begin prior to mating and continue throughout gestation (vi) the offspring of treated animals must exhibit the spectrum of malformations observed in the offspring of epileptic women The first criterion was met by mutant quaking (qk) mice. The seizure activity of these animals was reduced (from 2.1 to .34 seizures per mouse day) by DPH treatment. To separate the effect of this gene from that of the DPH in the etiology of the malformations, heterozygous (+/qk) and homozygous non- quaking (+/+) mice were also studied. Monitoring of DPH levels with the SYVA Emit spectrophotometry assay technique indicated serum concentrations within the human therapeutic range at 40 and 60 mg/kg body weight dosages. The incidence of fetuses born with skeletal or soft-tissue abnormalities increased with increasing DPH dosages. This was observed in all three genotypes. The ability of the untreated quaking (qk/qk) dams to -produce normal offspring implicates the drug rather than the mutant gene as the cause of malformations. A preliminary application of this animal model produced what can be considered the mouse equivalent of the fetal hydantion syndrome. The similarities between the human and mouse syndromes include prenatal growth deficiency, neural, cardiac, orofacial, ocular and genitourinary anomalies. Further large-scale application of the model should provide insight into the role of DPH in the etiology of the malformations observed amongst the offspring of epileptic women on hydantoin anticonvulsant drug therapy.

description: The description of spacetime is an fundamental problem of cosmology. We explain why the current assignments of spacetime geometries for $Ω_k$ of the Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) model are probably incorrect and suggest more useful descriptions. We show that $Ω_k$ represents not only curvature but the influence of matter density on the extent of spacetime between massive objects. Recent analyses of supernovae type Ia (SNe Ia) and HII/GEHR data with the FLRW model present the best fits with a small value for $Ω_m$ and a large $Ω_k$. These results are consistent with our Universe exhibiting sparse matter density and quasi-Euclidean geometry and the small $Ω_m$ value agrees with Big Bang nucleosynthesis calculations. We suggest the geometry of our current Universe is better described by a value for $Ω_k\approx$1 rather than 0. As an example we extend the FLRW model towards the Big Bang and discover a simple explanation of how matter creation developed into the currently geometrically flat Universe with sparse, homogeneous, isotropic matter and energy distributions. Assigning $Ω_k\approx1$ to describe quasi-Euclidean spacetime geometry is also useful for estimating $H_0$ and should help resolve the tension surrounding current estimates by different investigators.

description: We show how to simulate the equatorial section of the Schwarzschild metric through a flowing liquid crystal in its nematic phase. Inside a liquid crystal in the nematic phase, a traveling light ray feels an effective metric, whose properties are linked to perpendicular and parallel refractive indexes, $n_o$ e $n_e$ respectively, of the rod-like molecule of the liquid crystal. As these indexes depend on the scalar order parameter of the liquid crystal, the Beris-Edwards hydrodynamic theory is used to connect the order parameter with the velocity of a liquid crystal flow at each point. This way we calculate a radial velocity profile that simulates the equatorial section of the Schwarzschild metric, in the region outside of Schwarzschild's radius, in the nematic phase of the liquid crystal. In our model, the higher flow velocity can be of the order of some meters per second.

Cation-size mismatch as a predictive descriptor for structural distortion, configurational disorder, and valence-band splitting in II-IV-N$_2$ semiconductors

description: The II-IV-N$_2$ class of heterovalent ternary nitrides have gained significant interest as alternatives to the III-nitrides for electronic and optoelectronic applications. In this study, we apply first-principles calculations based on density functional theory to systematically investigate the effects of structural distortions due to cation size mismatch on the configurational disorder of the cation sublattice and the valence band structure in this class of materials. We find that larger size mismatch between the group-II and the group-IV cations results in stronger lattice distortions from the ideal hexagonal ratio, which in turn inhibits the propensity of these materials towards octet-rule violating cation disorder. We also demonstrate that the formation energy of a single cation antisite pair, which is fast and simple to calculate, is a strong indicator of a material's propensity towards disorder. Furthermore, the breaking of in-plane symmetry leads to a splitting of the top three valence bands at $Γ$, which is also directly related to the magnitude of structural distortions. Our work demonstrates that the structural and functional properties of the II-IV-N$_2$ materials can be finely tuned through controllable structural distortions that stem from the choice of cations.
Stability of converging shock wave
Creators: name: Fong, Kenneth Sau-Kin
Publisher: name: University of British Columbia
Year: 2010

description: The stability of converging waves was analysed with theory and by experiment. A computer code was written in FORTRAN language for the calculation of wavefront positions of plane shock waves and cylindrical converging shock waves in ideal gas. The criteria for stability were defined and the limit of stability of imploding shock waves was obtained using the code. In order to test the model, an experiment was set up to generate shock waves in an electrothermal shock tube. These shock waves were made to propagate into a wedged channel, and the variations of the shapes of the waves front were measured from high speed framing camera pictures. Good agreement was found between the experimentally observed velocity and the model calculation, indicating that the computer procedure is a valid method to analyse the stability of converging waves.

description: We may be well pleased to find ourselves living in a period of conscientious effort toward advancement, rather than in the age of decline a few centuries ago. At the present time, we are slowly mounting another curve. We are becoming aware that much must be done to give our mothers and babies the peace, comfort, and safety, science affords. In order to change such a low standing, we must turn to our state and inquire as to what she is doing.
Turbulent Flow in Pipes and Channels as Cross-Stream "Inverse Cascades" of Vorticity

description: A commonplace view of pressure-driven turbulence in pipes and channels is as "cascades" of streamwise momentum toward the viscous layer at the wall. We present in this paper an alternative picture of these flows as "inverse cascades" of spanwise vorticity, in the cross-stream direction but away from the viscous sublayer. We show that there is a constant spatial flux of spanwise vorticity, due to vorticity conservation, and that this flux is necessary to produce pressure-drop and energy dissipation. The vorticity transport is shown to be dominated by viscous diffusion at distances closer to the wall than the peak Reynolds stress, well into the classical log-layer. The Perry-Chong model based on "representative" hairpin/horsehoe vortices predicts a single sign of the turbulent vorticity flux over the whole log-layer, whereas the actual flux must change sign at the location of the Reynolds-stress maximum. Sign-reversal may be achieved by assuming a slow power-law decay of the Townsend "eddy intensity function" for wall-normal distances greater than the hairpin length-scale. The vortex-cascade picture presented here has a close analogue in the theory of quantum superfluids and superconductors, the "phase slippage" of quantized vortex lines. Most of our results should therefore apply as well to superfluid turbulence in pipes and channels. We also discuss issues about drag-reduction from this perspective.

Enhanced Diffusion of a Needle in a Planar Course of Point Obstacles

description: The transport of an infinitely thin, hard rod in a random, dense array of point obstacles is investigated by molecular dynamics simulations. Our model mimics the sterically hindered dynamics in dense needle liquids. The center-of-mass diffusion exhibits a minimum, and transport becomes increasingly fast at higher densities. The diffusion coefficient diverges according to a power law in the density with an approximate exponent of 0.8. This observation is connected with a new divergent time scale, reflected in a zig-zag motion of the needle, a two-step decay of the velocity-autocorrelation function, and a negative plateau in the non-Gaussian parameter.

description: Using the square-root map p-->\sqrt{p} a probability density function p can be represented as a point of the unit sphere S in the Hilbert space of square-integrable functions. If the density function depends smoothly on a set of parameters, the image of the map forms a Riemannian submanifold M in S. The metric on M induced by the ambient spherical geometry of S is the Fisher information matrix. Statistical properties of the system modelled by a parametric density function p can then be expressed in terms of information geometry. An elementary introduction to information geometry is presented, followed by a precise geometric characterisation of the family of Gaussian density functions. When the parametric density function describes the equilibrium state of a physical system, certain physical characteristics can be identified with geometric features of the associated information manifold M. Applying this idea, the properties of vapour-liquid phase transitions are elucidated in geometrical terms. For an ideal gas, phase transitions are absent and the geometry of M is flat. In this case, the solutions to the geodesic equations yield the adiabatic equations of state. For a van der Waals gas, the associated geometry of M is highly nontrivial. The scalar curvature of M diverges along the spinodal boundary which envelopes the unphysical region in the phase diagram. The curvature is thus closely related to the stability of the system.

description: Fast and reliable monitoring of volumetric heat distribution during MRI-guided tumor ablation is an urgent clinical need. In this work, we introduce a method for generating 2.5D thermometry maps from uniformly distributed 2D MRI phase images rotated around the applicator's main axis. The images can be fetched directly from the MR device, reducing the delay between image acquisition and visualization. For reconstruction, we use a weighted interpolation on a cylindric coordinate representation to calculate the heat value of voxels in a region of interest. A pilot study on 13 ex vivo bio protein phantoms with flexible tubes to simulate a heat sink effect was conducted to evaluate our method. After thermal ablation, we compared the measured coagulation zone extracted from the post-treatment MR data set with the output of the 2.5D thermometry map. The results show a mean Dice score of 0.75+-0.07, a sensitivity of 0.77+-0.03, and a reconstruction time within 18.02ms+-5.91ms. Future steps should address improving temporal resolution and accuracy, e.g., incorporating advanced bioheat transfer simulations.
