Intrinsic selection biases of ground-based gravitational wave searches for high-mass BH-BH mergers

The next generation of ground-based gravitational wave detectors may detect a few mergers of comparable-mass M\simeq 100-1000 Msun ("intermediate-mass'', or IMBH) spinning black holes. Black hole spin is known to have a significant impact on the orbit, merger signal, and post-merger ringdown of any binary with non-negligible spin. In particular, the detection volume for spinning binaries depends significantly on the component black hole spins. We provide a fit to the single-detector and isotropic-network detection volume versus (total) mass and arbitrary spin for equal-mass binaries. Our analysis assumes matched filtering to all significant available waveform power (up to l=6 available for fitting, but only l<= 4 significant) estimated by an array of 64 numerical simulations with component spins as large as S_{1,2}/M^2 <= 0.8. We provide a spin-dependent estimate of our uncertainty, up to S_{1,2}/M^2 <= 1. For the initial (advanced) LIGO detector, our fits are reliable for $M\in[100,500]M_\odot$ ($M\in[100,1600]M_\odot$). In the online version of this article, we also provide fits assuming incomplete information, such as the neglect of higher-order harmonics. We briefly discuss how a strong selection bias towards aligned spins influences the interpretation of future gravitational wave detections of IMBH-IMBH mergers.Comment: 18 pages, 15 figures, accepted by PRD. v2 is version accepted for publication, including minor changes in response to referee feedback and updated citation

A study of pulmonary function abnormalities in obese individuals

Background: Previous studies suggest that obese individuals are prone to pulmonary function abnormalities. The aim of this study was to evaluate pulmonary function tests in obese individuals and to relate pulmonary abnormalities if any found to lipid abnormalities and to the extent and duration of obesity.Methods: This prospective study was done on 40 obese patients attending to Dr. D. Y. Patil Hospital, Mumbai with complaints of pulmonary functions during the period from January to December 2012. Pulmonary function test was done with the help of Jaegers pneumoscreen. The percentage of body fat was determined by using triceps skin fold thickness technique by using Vernier callipers. Fasting serum samples was collected to analyses cholesterol and triglycerides.Results: Female preponderance was seen in the study (57.5%). Forced expiratory volume, forced vital capacity, maximum mid expiratory flow rate was significantly reduced and the ratio of forced expiratory volume in one second to forced vital capacity was significantly increased in individuals who had abnormal pulmonary function. Decrease in pulmonary function was noted with increased levels of cholesterol and triglyceride but the correlation was not significant.Conclusions: Obese individuals although asymptomatic have significant lung function abnormality in the form of restrictive as well as obstructive pattern. Hence, reduction in the body weight may help in reversal of the pulmonary function indices

Efficient Security Solution for Privacy Cloud Services

In this paper, we exhibit a novel protection protecting security answer for cloud services. We manage client nameless access to cloud benefits and imparted stockpiling servers. Our answer furnishes enlisted clients with unacknowledged access to cloud services. Our answer offers unacknowledged verification. This implies that clients' close to home qualities (age, legitimate enrollment, fruitful installment) can be demonstrated without uncovering clients' character. Accordingly, clients can utilize services without any risk of profiling their conduct. Then again, if clients break supplier's tenets, their right to gain entrance rights are renounced. We dissect current security safeguarding answers for cloud services and layout our answer in light of cutting edge cryptographic segments. Our answer offers nameless access, unlinkability and the privacy of transmitted information. Also, we execute our answer and we yield the trial comes about and look at the execution with related arrangements

Matter Wave Scattering and Guiding by Atomic Arrays

We investigate the possibility that linear arrays of atoms can guide matter waves, much as fiber optics guide light. We model the atomic line as a quasi-1D array of s wave point scatterers embedded in 2D. Our theoretical study reveals how matter wave guiding arises from the interplay of scattering phenomena with bands and conduction along the array. We discuss the conditions under which a straight or curved array of atoms can guide a beam focused at one end of the array.Comment: Submitted to Phys. Rev.

Experiences of racial microaggressions, relational mentoring, and social connectedness among doctoral students of color within counselor education programs

In educational systems, students of color experience oppression and subtle forms of racism (i.e., microaggressions), often directed towards them by their peers and faculty in the program (Gildersleeve, Croom, &amp; Vasquez, 2011; Kohli &amp; Solorzano, 2012; McCabe, 2009; Sue, Lin, Capodilupo, Torino, &amp; Rivera, 2009). As a result, students of color experience discomfort, self-doubt, exhaustion, and isolation (Gildersleeve et al., 2011; McCabe, 2009). Further, race related experiences (such as microaggressions) in academia have been noted to impact an individual’s social connectedness (or sense of belonging) with peers, faculty, and the academic program (Clark, Mercer, Zeigler-Hill, &amp; Dufrene, 2012; Solorzano, 1998; Suarez-Orozco et al., 2015). There is a need to quantify the impact of racial microaggressions on social connectedness in a heterogeneous sample that can be generalized to students of color in higher education, and more specifically to doctoral students of color in Counselor Education (CE). As doctoral programs recruit more students of color, we must strive to examine the dominant discourse that inadvertently oppresses students of color in academia, specifically the important role of mentoring in fostering social connectedness in CE programs. The purpose of this study was to address the gap in literature on the prevalence of racial microaggressions in CE programs and to examine how racial microaggressions and the moderating role of mentoring by one’s advisor/dissertation chair could impact doctoral students of color’s social connectedness within their academic program. A descriptive, correlational design was utilized to examine this impact of racial microaggressions and the buffering relationship of relational mentoring on social connectedness. Relational Cultural Theory (RCT; Miller, 1976, 1986) was the theoretical framework used to boundary the relationship between racial microaggressions and social connectedness because it explained the overall negative impact of racial microaggressions on social connectedness. Results from this study indicated that racial microaggressions do exist in CE programs and negatively impact the social connectedness of doctoral students of color within their academic department. Further, relational mentoring by a dissertation chair/academic advisor did buffer this impact of racial microaggressions on social connectedness. The results provide important outcomes for counselor educators and CE programs as we strive to promote diversity, equity, recruitment, and retention of doctoral students of color. Implications for counselor educators, doctoral students, and researchers are discussed based on the results of the study

Room Temperature Detection of Benzene Vapours by Tin Oxide Nano Clusters

Abstract: Thin films of tin oxide with nano clusters were deposited using Chemical Vapour Transport technique. The annealed films were used as sensor to detect benzene vapours at room temperature. The response was studied for the concentration range 300-1000 ppm. A comparative study of the response of the nano clustered films to benzene vapours in this range with the response of thin films of Indium tin oxide and tin oxide deposited by the physical vapour deposition method was taken up

Isolation and partial purification of erythromycin from alkaliphilic Streptomyces werraensis isolated from Rajkot, India

AbstractAn alkaliphilic actinomycete, BCI-1, was isolated from soil samples collected from Saurashtra University campus, Gujarat. Isolated strain was identified as Streptomyces werraensis based on morphological, biochemical and phylogenetic analysis. Maximum antibiotic production was obtained in media containing sucrose 2%, Yeast extract 1.5%, and NaCl 2.5% at pH 9.0 for 7 days at 30 °C. Maximum inhibitory compound was produced at pH 9 and at 30 °C. FTIR revealed imine, amine, alkane (CC) of aromatic ring and p-di substituted benzene, whereas HPLC analysis of partially purified compound and library search confirmed 95% peaks matches with erythromycin. Chloroform extracted isolated compound showed MIC values 1 μg/ml against Bacillus subtilis, ≤0.5 μg/ml against Staphylococcus aureus, ≤0.5 μg/ml against Escherichia coli and 2.0 μg/ml against Serretia GSD2 sp., which is more effective in comparison to ehtylacetate and methanol extracted compounds. The study holds significance as only few alkaliphilic actinomycetes have been explored for their antimicrobial potential

Quantum circuits for spin and flavor degrees of freedom of quarks forming nucleons

We discuss the quantum-circuit realization of the state of a nucleon in the scope of simple symmetry groups. Explicit algorithms are presented for the preparation of the state of a neutron or a proton as resulting from the composition of their quark constituents. We estimate the computational resources required for such a simulation and design a photonic network for its implementation. Moreover, we highlight that current work on three-body interactions in lattices of interacting qubits, combined with the measurement-based paradigm for quantum information processing, may also be suitable for the implementation of these nucleonic spin states.Comment: 5 pages, 2 figures, RevTeX4; Accepted for publication in Quantum Information Processin
