A prospective comparative study to evaluate the efficacy and safety of mifepristone with misoprostol over misoprostol alone in induction of labour

Background: The clinical requirement for induction of labour arises from circumstances in which it is predicted that the outcome of the pregnancy will be better if it is artificially interrupted rather than being left to follow its natural course. The combination of Mifepristone and Misoprostol is now an established and highly effective and safe method for second and third trimester termination of pregnancy and also significantly reduces the induction delivery interval, has fewer side effects and complications and also reduces the dose of Misoprostol. Hence, an attempt is made in the present study to assess the efficacy of combination of Mifepristone and Misoprostol versus single drug Misoprostol alone for induction of labor.Methods: A prospective comparative study of 50 cases in each study group, one under Misoprostol induction (group 1) and one under Mifepristone plus Misoprostol induction (group 2) were done and observations made in terms of improvement in Bishop’s score, induction-delivery interval and requirement of subsequent doses of Misoprostol.Results: 64% of the patients were observed with improved Bishop’s score. Induction delivery interval was shorter in the group 2 and noteworthy feature is 46% patients did not require even a single dose of Misoprostol after cervical ripening with Mifepristone suggesting that only Mifepristone may be only drug required in future for induction.Conclusions: Mifepristone with Misoprostol is efficient combination for induction of labour as compared to Misoprostol alone

A study of tropical tropopause using MST radar

International audienceUsing the MST radar data of vertical wind, the characteristics of the tropical tropopause, following four different definitions, depending on 1) temperature lapse rate, 2) cold point, 3) convective outflow and 4) potential temperature lapse rate minimum, are studied. From the vertical wind data of the radar, the altitude profiles of temperature and horizontal divergence are derived, from which the tropopause levels corresponding to i) the lapse rate ii) cold point iii) convective outflow level and iv) potential temperature lapse rate minimum are determined. The convective outflow level and hence the convective tropopause altitude is determined, for the first time using the MST radar data. The tropopause altitudes and temperatures obtained following the four definitions are compared on a day-to-day basis for the summer and winter seasons. Winter and summer differences in the tropopause altitude and temperature are also studied. Keywords. Meteorology and atmospheric dynamics (convective process; middle atmosphere dynamics; tropical meteorology

Gravity waves observed from the Equatorial Wave Studies (EWS) campaign during 1999 and 2000 and their role in the generation of stratospheric semiannual oscillations

International audienceThe altitude profiles of temperature fluctuations in the stratosphere and mesosphere observed with the Rayleigh Lidar at Gadanki (13.5° N, 79.2° E) on 30 nights during January to March 1999 and 21 nights during February to April 2000 were analysed to bring out the temporal and vertical propagation characteristics of gravity wave perturbations. The gravity wave perturbations showed periodicities in the 0.5?3-h range and attained large amplitudes (4?5 K) in the mesosphere. The phase propagation characteristics of gravity waves with different periods showed upward wave propagation with a vertical wavelength of 5?7 km. The mean flow acceleration computed from the divergence of momentum flux of gravity waves is compared with that calculated from monthly values of zonal wind obtained from RH-200 rockets flights. Thus, the contribution of gravity waves towards the generation of Stratospheric Semi Annual Oscillation (SSAO) is estimated

Feature Selection for Gabor Filter Based on Level Measurement using Non-Interacting Tanks Level Images

Level measurement models using image-based classifiers (pixel-based datasets) are used for estimation purposes. Pre-processing is thought-provoking in proceeding out the image filter technique and classifying the level. The level scenario of a two non-interacting tank system plays a vital role in predicting the level. Level monitoring is done using the supervised learning method using instance-based filters (Gabor Filter) and selected base classifiers for level measurements. The main scope of this case study is to improve the level measurements from the two non-interacting tank scenarios using Artificial Intelligent algorithms. The suggested article includes the finest feature selection process to increase the accuracy performance attained by the designated classifiers like IBK Instance base classifier for different neighbourhood values and Tree category algorithm like Random Forest. The performance accuracy in level prediction obtained is 81.356%, the weighted Average of Receiver operator characteristics of (ROC) 0.931 are obtained by Random Forest Tree Category Classifie

Observational constrained F(R,G)F(R, \mathcal{G}) gravity cosmological model and the dynamical system analysis

In this paper, we have analyzed the geometrical and dynamical parameters of $\mathcal{F}(R, \mathcal{G})=\alpha R^2 \mathcal{G}^\beta$ cosmological model, ($R$, $\mathcal{G}$ being the Ricci scalar and Gauss-Bonnet invariant respectively), constraining the parameters through the cosmological data sets. It is exhibited that the model admits a viable radiation era, and early deceleration followed by late-time acceleration in the matter-dominated era. From the phase-space, portrait stability criterion has been analysed, restricting the parameter $\beta$, different from $\beta=-1$. Additionally, we have explored the stability of the model from the behavior of critical points and obtained the present value of the density parameter for matter-dominated and dark energy components, which are identical to those obtained through cosmological data sets.Comment: 22 pages, 6 figure

Stability in Non-Normal Periodic Jacobi Operators: Advancing B\"org's Theorem

Periodic Jacobi operators naturally arise in numerous applications, forming a cornerstone in various fields. The spectral theory associated with these operators boasts an extensive body of literature. Considered as discretized counterparts of Schr\"odinger operators, widely employed in quantum mechanics, Jacobi operators play a crucial role in mathematical formulations. The classical uniqueness result by G. B\"org in $1946$ occupies a significant place in the literature of inverse spectral theory and its applications. This result is closely intertwined with M. Kac's renowned article, 'Can one hear the shape of a drum?' published in $1966$. Since $1975,$ discrete versions of B\"org's theorem have been available in the literature. In this article, we concentrate on the non-normal periodic Jacobi operator and the discrete versions of B\"org's Theorem. We extend recently obtained stability results to encompass non-normal cases. The existing stability findings establish a correlation between the oscillations of the matrix entries and the size of the spectral gap. Our result encompasses the current self-adjoint versions of B\"org's theorem, including recent quantitative variations. Here, the oscillations of the matrix entries are linked to the path-connectedness of the pseudospectrum. Additionally, we explore finite difference approximations of various linear differential equations as specific applications

The Origin of X-shaped Radio Galaxies: Clues from the Z-symmetric Secondary Lobes

Existing radio images of a few X-shaped radio galaxies reveal Z-symmetric morphologies in their weaker secondary lobes which cannot be naturally explained by either the galactic merger or radio-lobe backflow scenarios, the two dominant models for these X-shaped radio sources. We show that the merger picture can explain these morphologies provided one takes into account that, prior to the coalescence of their supermassive black holes, the smaller galaxy releases significant amounts of gas into the ISM of the dominant active galaxy. This rotating gas, whose angular momentum axis will typically not be aligned with the original jets, is likely to provide sufficient ram pressure at a distance ~10 kpc from the nucleus to bend the extant jets emerging from the central engine, thus producing a Z-symmetry in the pair of radio lobes. Once the two black holes have coalesced some 10^7 yr later, a rapid reorientation of the jets along a direction close to that of the orbital angular momentum of the swallowed galaxy relative to the primary galaxy would create the younger primary lobes of the X-shaped radio galaxy. This picture naturally explains why such sources typically have powers close to the FR I/II break. We suggest that purely Z-symmetric radio sources are often en route to coalescence and the concomitant emission of substantial gravitational radiation, while X-shaped ones have already merged and radiated.Comment: 12 pages, 1 compressed figure; accepted for publication in ApJ Letter
