We present a constraint on the tensor-to-scalar ratio, r, derived from measurements of cosmic microwave background (CMB) polarization B-modes with "delensing," whereby the uncertainty on r contributed by the sample variance of the gravitational lensing B-modes is reduced by cross-correlating against a lensing B-mode template. This template is constructed by combining an estimate of the polarized CMB with a tracer of the projected large-scale structure. The large-scale-structure tracer used is a map of the cosmic infrared background derived from Planck satellite data, while the polarized CMB map comes from a combination of south Pole Telescope, Bicep/Keck, and Planck data. We expand the Bicep/Keck likelihood analysis framework to accept a lensing template and apply it to the Bicep/Keck data set collected through 2014 using the same parametric foreground modelling as in the previous analysis. From simulations, we find that the uncertainty on r is reduced by ∼ 10%, from σ(r)= 0.024 to 0.022, which can be compared with a ∼ 26% reduction obtained when using a perfect lensing template or if there were zero lensing B-modes. Applying the technique to the real data, the constraint on r is improved from r0.05 Copyright © 2020, The Authors. All rights reserved.

specialized computational chemistry packages have permanently reshaped the landscape of chemical and materials science by providing tools to support and guide experimental efforts and for the prediction of atomistic and electronic properties. In this regard, electronic structure packages have played a special role by using first-principle-driven methodologies to model complex chemical and materials processes. Over the last few decades, the rapid development of computing technologies and the tremendous increase in computational power have offered a unique chance to study complex transformations using sophisticated and predictive many-body techniques that describe correlated behavior of electrons in molecular and condensed phase systems at different levels of theory. In enabling these simulations, novel parallel algorithms have been able to take advantage of computational resources to address the polynomial scaling of electronic structure methods. In this paper, we briefly review the NWChem computational chemistry suite, including its history, design principles, parallel tools, current capabilities, outreach and outlook.

In this paper, we present an experiment conducted for comparing how experts and students assess the quality of class diagrams. six quality attributes were addressed: Understandability, Layout, Extensibility, Modifiability, Completeness and Correctness. From this study, we aim to find out how well students are capable of evaluating the quality of UML designs. Moreover, we aim to learn which features experts and students use for assessing the quality attrib-utes of class diagrams. The study reveals that experts and students' assessment of the six quality attributes differ significantly. However, a qualitative analysis of experts and students' feedback suggests that students use similar features as experts use for assessing the quality of diagrams. Hence peer-feedback from stu-dents can be useful in educational settings. © Copyright 2015 for the individual papers by the papers' authors.

In Data structures, sorting is a technique which is used for arranging data in a particular order either ascending or descending. sorting techniques like Bubble sort, Insertion sort and selection sort are comparison based. Our proposed technique is a combination of both comparison and counting based techniques. We are finding the exact position of an element and placing it in its corresponding position. A sorting technique is said to be optimal based on its time & space complexity. The algorithm we designed is said to be optimal, based on the number of swap's compared to existing techniques like bubble sort, insertion sort.

International Conference on (IsCO) Intelligent systems and Control

作者： T. Maruthi Padmaja P. Jhansi Lakshmi Dept. of Computer Science and Engineering Vignan's University Guntur A.P India

One-Class support Vector Machines (OCsVM) is widely applied for those classification problems where one of the classes of data is completely not present or not properly sampled. However, the knowledge presented by OCsVM is not interpretable by the human analyst. To ameliorate this problem there is a need for providing explanation aids to OCsVM classification decisions. Recently, several rule extraction methods were evolved to provide explanation ability to support Vector Machines (sVM) and Artificial Neural Networks (ANN). Motivated from these methods this paper proposes a new hybrid rule extraction method for OCsVM, which is not widely studied yet. Proposed hybrid is composed with support Vector Data Description (sVDD) and RIPPER rule learning. The viability of the proposed hybrid is tested over three benchmark datasets. Obtained results have shown that sVDD+RIPPER hybrid outperformed sVDD and RIPPER alone in terms of classification performance and explanation ability.

We present new arcminute-resolution maps of the Cosmic Microwave Background temperature and polarization anisotropy from the Atacama Cosmology Telescope, using data taken from 2013-2016 at 98 and 150 GHz. The maps cover more than 17,000 deg2, the deepest 600 deg2 with noise levels below 10µK-arcmin. We use the power spectrum derived from almost 6,000 deg2 of these maps to constrain cosmology. The ACT data enable a measurement of the angular scale of features in both the divergence-like polarization and the temperature anisotropy, tracing both the velocity and density at last-scattering. From these one can derive the distance to the last-scattering surface and thus infer the local expansion rate, H0. By combining ACT data with large-scale information from WMAP we measure H0 = 67.6±1.1 km/s/Mpc, at 68% confidence, in excellent agreement with the independently-measured Planck satellite estimate (from ACT alone we find H0 = 67.9 ±1.5 km/s/Mpc). The ΛCDM model provides a good fit to the ACT data, and we find no evidence for deviations: both the spatial curvature, and the departure from the standard lensing signal in the spectrum, are zero to within 1σ;the number of relativistic species, the primordial Helium fraction, and the running of the spectral index are consistent with ΛCDM predictions to within 1.5-2.2σ. We compare ACT, WMAP, and Planck at the parameter level and find good consistency;we investigate how the constraints on the correlated spectral index and baryon density parameters readjust when adding CMB large-scale information that ACT does not measure. The DR4 products presented here will be publicly released on the NAsA Legacy Archive for Microwave Background Data Analysis. Copyright © 2020, The Authors. All rights reserved.

We present the temperature and polarization angular power spectra of the CMB measured by the Atacama Cosmology Telescope (ACT) from 5400 deg2 of the 2013-2016 survey, which covers >15000 deg2 at 98 and 150 GHz. For this analysis we adopt a blinding strategy to help avoid confirmation bias and, related to this, show numerous checks for systematic error done before unblinding. Using the likelihood for the cosmological analysis we constrain secondary sources of anisotropy and foreground emission, and derive a "CMB-only" spectrum that extends to = 4000. At large angular scales, foreground emission at 150 GHz is ∼1% of TT and EE within our selected regions and consistent with that found by Planck. Using the same likelihood, we obtain the cosmological parameters for ΛCDM for the ACT data alone with a prior on the optical dept. of τ = 0.065 ± 0.015. ΛCDM is a good fit. The best-fit model has a reduced χ2 of 1.07 (PTE = 0.07) with H0 = 67.9 ± 1.5 km/s/Mpc. We show that the lensing BB signal is consistent with ΛCDM and limit the celestial EB polarization angle to ψP = −0.07◦ ± 0.09◦. We directly cross correlate ACT with Planck and observe generally good agreement but with some discrepancies in TE. All data on which this analysis is based will be publicly released.
