    Background: Assisted reproductive technology (ART) cycles include in vitro fertilization of the sperm and ovum and transferring the embryo formed into the uterus of the patients. In ART cycles, there is still a shroud of doubt regarding the pregnancy outcomes of embryo transfer on day 3 versus the embryo transfers on day 5 as well the better pregnancy outcome with fresh versus frozen embryo transfer and the number of embryos transferred. This study is aimed to evaluate these factors and study the way to optimize methods to obtain highest pregnancy outcomes.Methods: A retrospective study was performed of 87 patients who had undergone embryo transfers during the duration of the study from an IVF centre in Ahmedabad. Multiple factors were studied and the clinical outcome was tabulated. The pregnancy outcomes were compared using the values of beta- hcg (human chorionic gonadotropin). The data was compiled and analyzed using Google spreadsheets. To find the statistical difference between different factors- the statistical method of Fischer’s exact test and p-value was used.Results: No statistical difference between day 3 and day 5 embryo transfer as well as between frozen and fresh embryo transfer were both. All of them were found equally efficacious, although 3 and 5 number of embryo transfers were found efficacious.Conclusions: In conclusion authors recommend a day 5 embryo transfer with 3 or 5 embryos which are best-quality frozen or fresh embryos to achieve maximum pregnancy outcomes

    Churn Prediction using MapReduce and HBase.

    The mobile telecommunication market is rapidly increasing with numerous service providers stepping in the market. This makes the customer think to leave the service provided by one service provider and move to another service provider for some better offers. This project is an attempt to design and implement an application that can take Customer Records as input and give Customer churn prediction details as output. It will enable service provider to know in advance about the valuable customer who are about to churn. By merely giving customer data records as input, user can get the desired customer behaviour pattern, which is the churn output. The output obtained will basically distinguish the churners and the non-churners. The system is built using Apache Hadoop, Apache HBase and a Data Mining Algorithm under MapReduce code. The use of Hadoop framework makes it easy to process the large datasets containing the information of customers. DOI: 10.17762/ijritcc2321-8169.150317

    LASAGNA PLOTS: A SAUCY ALTERNATIVE TO SPAGHETTI PLOTS

    Longitudinal repeated measures data has often been visualized with spaghetti plots for continuous out- comes. For large datasets, this often leads to over-plotting and consequential obscuring of trends in the data. This is primarily due to overlapping of trajectories. Here, we suggest a framework called lasagna plot ting that constrains the subject-specific trajectories to prevent overlapping and utilizes gradients of color to depict the outcome. Dynamic sorting and visualization is demonstrated as an exploratory data analysis tool. Supplemental material in the form of sample R code additional illustrated examples are available online

    Determination of two-photon exchange amplitudes from elastic electron-proton scattering data

    Full text link
    Using the available cross section and polarization data for elastic electron-proton scattering, we provide an extraction of the two-photon exchange amplitudes at a common value of four-momentum transfer, around Q^2 = 2.5 GeV^2. This analysis also predicts the e^+ p / e^- p elastic scattering cross section ratio, which will be measured by forthcoming experiments.Comment: 4 pages, 5 figures, updated error analysi

    A Comparison of Polarization Observables in Electron Scattering from the Proton and Deuteron

    Recoil proton polarization observables were measured for both the p(e\vec {\rm e},ep^\prime\vec{\rm p}\,) and d(e\vec {\rm e},ep)^\prime\vec{\rm p}\,)n reactions at two values of Q2^2 using a newly commissioned proton Focal Plane Polarimeter at the M.I.T.-Bates Linear Accelerator Center. The hydrogen and deuterium spin-dependent observables DD_{\ell\ell} and DtD_{{\ell}t}, the induced polarization PnP_n and the form factor ratio GEp/GMpG^p_E/G^p_M were measured under identical kinematics. The deuterium and hydrogen results are in good agreement with each other and with the plane-wave impulse approximation (PWIA).Comment: 9 pages, 1 figure; accepted by Phys. Rev. Let

    Implication of the overlap representation for modelling generalized parton distributions

    Get PDF
    Based on a field theoretically inspired model of light-cone wave functions, we derive valence-like generalized parton distributions and their double distributions from the wave function overlap in the parton number conserved s-channel. The parton number changing contributions in the t-channel are restored from duality. In our construction constraints of positivity and polynomiality are simultaneously satisfied and it also implies a model dependent relation between generalized parton distributions and transverse momentum dependent parton distribution functions. The model predicts that the t-behavior of resulting hadronic amplitudes depends on the Bjorken variable x_Bj. We also propose an improved ansatz for double distributions that embeds this property.Comment: 15 pages, 8 eps figure

    20 Years of Progress in Typhoid Research

    In 1981, the reported number of cases of typhoid fever in Indonesia was 19,596, increasing to 26,606 m 1986, most of the increase was due to improved detection and recognition of the pathogen. A more realistic estimate of incidence for this underreported and underdiagnosed disease would be from 540,000 to 1,210,000 cases per year. This was based on results of a household survey done by Budiarso R. et al. in 1980 and 1986, and on result of a community surveillance done by Ruwido and Simanjuntak et al. from 1983-1988. These studies were done in Plaju, South Sumatera, representing an urban area and Paseh, West Java, representing a semi-rural area. The results showed that the incidence rate of typhoid fever in the semi rural area was 358/100,000 population/year, and between 760-810/100,000 population/year in the urban area. These studies also indicated that the high risk group in the population was school age children between ages of 3-19 years. From other observations, it is also noted that the case fatality in urbanized and growing areas of Indonesia, may be higher than it is reported in other areas of the worl

    Study objectivesCurrent evidence in adults suggests that, independent of obesity, obstructive sleep apnea (OSA) can lead to autonomic dysfunction and impaired glucose metabolism, but these relationships are less clear in children. The purpose of this study was to investigate the associations among OSA, glucose metabolism, and daytime autonomic function in obese pediatric subjects.MethodsTwenty-three obese boys participated in: overnight polysomnography; a frequently sampled intravenous glucose tolerance test; and recordings of spontaneous cardiorespiratory data in both the supine (baseline) and standing (sympathetic stimulus) postures.ResultsBaseline systolic blood pressure and reactivity of low-frequency heart rate variability to postural stress correlated with insulin resistance, increased fasting glucose, and reduced beta-cell function, but not OSA severity. Baroreflex sensitivity reactivity was reduced with sleep fragmentation, but only for subjects with low insulin sensitivity and/or low first-phase insulin response to glucose.ConclusionsThese findings suggest that vascular sympathetic activity impairment is more strongly affected by metabolic dysfunction than by OSA severity, while blunted vagal autonomic function associated with sleep fragmentation in OSA is enhanced when metabolic dysfunction is also present
