Testing the multipole structure and conservative dynamics of compact binaries using gravitational wave observations: The spinning case

In an earlier work [S. Kastha et al., PRD {\bf 98}, 124033 (2018)], we developed the {\it parametrized multipolar gravitational wave phasing formula} to test general relativity, for the non-spinning compact binaries in quasi-circular orbit. In this paper, we extend the method and include the important effect of spins in the inspiral dynamics. Furthermore, we consider parametric scaling of PN coefficients of the conserved energy for the compact binary, resulting in the parametrized phasing formula for non-precessing spinning compact binaries in quasi-circular orbit. We also compute the projected accuracies with which the second and third generation ground-based gravitational wave detector networks as well as the planned space-based detector LISA will be able to measure the multipole deformation parameters and the binding energy parameters. Based on different source configurations, we find that a network of third-generation detectors would have comparable ability to that of LISA in constraining the conservative and dissipative dynamics of the compact binary systems. This parametrized multipolar waveform would be extremely useful not only in deriving the first upper limits on any deviations of the multipole and the binding energy coefficients from general relativity using the gravitational wave detections, but also for science case studies of next generation gravitational wave detectors.Comment: 16 pages, 8 figures, Mathematica readable supplemental material file for all the inputs to calculate the parametrized waveform is with the sourc

Multiparameter tests of general relativity using multiband gravitational-wave observations

In this Letter we show that multiband observations of stellar-mass binary black holes by the next generation of ground-based observatories (3G) and the space-based Laser Interferometer Space Antenna (LISA) would facilitate a comprehensive test of general relativity by simultaneously measuring all the post-Newtonian (PN) coefficients. Multiband observations would measure most of the known PN phasing coefficients to an accuracy below a few percent---two orders-of-magnitude better than the best bounds achievable from even `golden' binaries in the 3G or LISA bands. Such multiparameter bounds would play a pivotal role in constraining the parameter space of modified theories of gravity beyond general relativity.Comment: 7 pages, 4 figures. v3: version published in PR

Spontaneous closure of the hymen during term pregnancy

The hymen is a thin fold of mucous membrane; partially closing the external vaginal opening.1It is composed mainly of elastic, collagenous connective tissue and covered on its both surfaces by stratified squamous epithelium. At pregnancy, the epithelium of hymen becomes very thick and rich in glycogen, which may lead to spontaneous closure. We aim to report a rare case of spontaneous closure of hymen in a 23-year old primigravida in labour with no prior history of menstrual problems or problems during intercourse. Two conditions can cause the secondary closure of the hymen: following previous scarring and in pregnancy. In pregnancy, it could be spontaneous closure due to increase glycogen content of the hymen or due to extensive scarring as seen in previous hymenal surgeries. Spontaneous closure of hymen during pregnancy though very rare can occur. Along with extensive scarring, prolonged abstinence and oestrogenic effect on hymen, gonococcal infection can also cause sponatenous closure of hymen during pregnancy.

Griffiths phase-like behaviour and spin-phonon coupling in double perovskite Tb2_{2}NiMnO6_{6}

The Griffiths phase-like features and the spin-phonon coupling effects observed in Tb$_2$NiMnO$_6$ are reported. The double perovskite compound crystallizes in monoclinic $P2_1/n$ space group and exhibits a magnetic phase transition at $T_c \sim$ 111 K as an abrupt change in magnetization. A negative deviation from ideal Curie-Weiss law exhibited by 1/$\chi(T)$ curves and less-than-unity susceptibility exponents from the power-law analysis of inverse susceptibility are reminiscent of Griffiths phase-like features. Arrott plots derived from magnetization isotherms support the inhomogeneous nature of magnetism in this material. The observed effects originate from antiferromagnetic interactions which arise from inherent disorder in the system. Raman scattering experiments display no magnetic-order-induced phonon renormalization below $T_c$ in Tb$_2$NiMnO$_6$ which is different from the results observed in other double perovskites and is correlated to the smaller size of the rare earth. The temperature evolution of full-width-at-half-maximum for the {\it stretching} mode at 645 cm$^{-1}$ presents an anomaly which coincides with the magnetic transition temperature and signals a close connection between magnetism and lattice in this material.Comment: 17 pages, 8 figures; accepted in J.

Cellular Correlates of Enhanced Anxiety Caused by Acute Treatment with the Selective Serotonin Reuptake Inhibitor Fluoxetine in Rats

Selective serotonin reuptake inhibitors (SSRIs) are used extensively in the treatment of depression and anxiety disorders. The therapeutic benefits of SSRIs typically require several weeks of continuous treatment. Intriguingly, according to clinical reports, symptoms of anxiety may actually increase during the early stages of treatment although more prolonged treatment alleviates affective symptoms. Consistent with earlier studies that have used animal models to capture this paradoxical effect of SSRIs, we find that rats exhibit enhanced anxiety-like behavior on the elevated plus-maze 1 h after a single injection of the SSRI fluoxetine. Next we investigated the potential neural substrates underlying the acute anxiogenic effects by analyzing the morphological and physiological impact of acute fluoxetine treatment on principal neurons of the basolateral amygdala (BLA), a brain area that plays a pivotal role in fear and anxiety. Although earlier studies have shown that behavioral or genetic perturbations that are anxiogenic for rodents also increase dendritic spine density in the BLA, we find that a single injection of fluoxetine does not cause spinogenesis on proximal apical dendritic segments on BLA principal neurons an hour later. However, at the same time point when a single dose of fluoxetine caused enhanced anxiety, it also enhanced action potential firing in BLA neurons in ex vivo slices. Consistent with this finding, in vitro bath application of fluoxetine caused higher spiking frequency and this increase in excitability was correlated with an increase in the input resistance of these neurons. Our results suggest that enhanced excitability of amygdala neurons may contribute to the increase in anxiety-like behavior observed following acute fluoxetine treatment

Anaemia in pregnancy: prevalence and treatment response to various modalities: a prospective study

Background: Anaemia seen in pregnancy are largely preventable and easily treatable if detected in time, despite this, anaemia still continues to be a common cause of maternal and perinatal morbidity and mortality in India.Methods: A prospective observational study of 200 pregnant women with anaemia was carried out from Jun 2017 to December 2018 at a Tertiary care hospital with pan India population. Patients underwent clinical examination and laboratory tests to find out the severity and type of anaemia and were treated accordingly. Iron deficiency anaemia was treated with oral or intravenous iron therapy depending upon the hemoglobin concentration. Patients were followed up after 28 days of treatment and hemoglobin estimation was done to monitor the treatment response.Results: A total 36.49% pregnant women had hemoglobin less than 10 gm%. 151 out of 200 women had serum ferritin <12 ng/ml which indicates that iron deficiency anaemia is the commonest type of anaemia in pregnancy. Overall, out of 200 patients 5.5% patients were found to have hemoglobinopathies (β thalassemia trait). After 28 days of treatment mean increase in hemoglobin was 2.40 gm% and 4.24 gm% in patients receiving oral and intravenous iron therapy respectively.Conclusions: A total 36.49% pregnant women were found to have anaemia during pregnancy and iron deficiency anaemia is the commonest type of anaemia. Therefore, there is still a need for dietary counselling and health education in the community. 5.5% patients were found to have beta thalassemia trait which was detected only after conducting hemoglobin electrophoresis. Both oral and intravenous iron therapy are effective in treatment of iron deficiency anaemia but intravenous iron therapy results in a more rapid resolution of anaemia
