In-beam γ-ray spectroscopy of Cu79 is performed at the Radioactive Isotope Beam Factory of RIKEN. The nucleus of interest is produced through proton knockout from a Zn80 beam at 270 MeV/nucleon. The level scheme up to 4.6 MeV is established for the first time and the results are compared to Monte Carlo shell-model calculations. We do not observe significant knockout feeding to the excited states below 2.2 MeV, which indicates that the Z=28 gap at N=50 remains large. The results show that the Cu79 nucleus can be described in terms of a valence proton outside a Ni78 core, implying the magic character of the latter.

We calculate the leptonic decay constants of heavy-light pseudoscalar mesons with charm and bottom quarks in lattice quantum chromodynamics on four-flavor QCD gauge-field configurations with dynamical u, d, s, and c quarks. We analyze over twenty isospin-symmetric ensembles with six lattice spacings down to a ≈ 0.03 fm and several values of the light-quark mass down to the physical value21(mu + md). We employ the highly-improved staggered-quark (HISQ) action for the sea and valence quarks;on the finest lattice spacings, discretization errors are sufficiently small that we can calculate the B-meson decay constants with the HISQ action for the first time directly at the physical b-quark mass. We obtain the most precise determinations to-date of the D- and B-meson decay constants and their ratios, fD+ = 212.7(0.6) MeV, fDs = 249.9(0.4) MeV, fDs/fD+ = 1.1749(16), fB+ = 189.4(1.4) MeV, fBs = 230.7(1.3) MeV, fBs/fB+ = 1.2180(47), where the errors include statistical and all systematic uncertainties. Our results for the B-meson decay constants are three times more precise than the previous best lattice-QCD calculations, and bring the QCD errors in the Standard-Model predictions for the rare leptonic decays B(Bs → µ+µ−) = 3.64(11) × 10−9, B(B0 → µ+µ−) = 1.00(3) × 10−10, and B(B0 → µ+µ−)/B(Bs → µ+µ−) = 0.0273(9) to well below other sources of uncertainty. As a byproduct of our analysis, we also update our previously published results for the light-quark-mass ratios and the scale-setting quantities fp4s, Mp4s, and Rp4s. We obtain the most precise lattice-QCD determination to date of the ratio fK+/fπ+ = 1.1950(+16−23) MeV. Copyright © 2017, The Authors. All rights reserved.

A Two-Level Multithreaded Delaunay Kernel

This paper presents a fine grain parallel version of the 3D Delaunay Kernel procedure using the OpenMP (Open Multi-Processing) API. A set S = { p 1 ,. . ., p n } of n points is taken as input. S is initially sorted along a space-filling curve so that two points that are close in the insertion order are also close geometrically. The sorted set of point is then divided into M subsets S i , 1 ≤ i ≤ M of equal size n/M . The multithreaded version of the Delaunay kernel inserts M points at a time in the triangulation. OpenMP barriers provide the required synchronization that is needed after each multiple insertion in order to avoid data races. This simple approach exhibits two standard problems of parallel computing: load imbalance and parallel overheads. Those two issues are addressed using a two-level version of the multithreaded Delaunay kernel. Tests show that triangulations of about a billion tetrahedra can be generated on a 32 core machine (Intel Xeon E5-4610 v2 @ 2.30 GHz with with 128 GB of memory) in less that 3 minutes of wall clock time, with a speedup of 18 compared to the single-threaded implementation.

This paper proposes a robot interface design method by which we can control humanoid end-effector movements with such a low-dimensional input device as a gamepad. In our proposed method, first, the numbers of movement trajectories to accomplish different tasks are generated using a simulated robot model and stored in a database. Second, a human user demonstrates the current task-related behavior. Third, the corresponding stored movements for the demonstrated human behavior are sparsely extracted by a sparse coding method. Finally, the sparsely extracted movement bases are linearly combined to generate a novel movement to accomplish a new target task where the linear weight parameters are modulated by the gamepad. We easily generated such complicated hand movements as spiral motions on a small humanoid robot with our proposed interface.

The Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) is a three-layered imaging survey aimed at addressing some of the most outstanding questions in astronomy today, including the nature of dark matter and dark energy. The survey has been awarded 300 nights of observing time at the Subaru Telescope and it started in March 2014. This paper presents the first public data release of HSC-SSP. This release includes data taken in the first 1.7 years of observations (61.5 nights) and each of the Wide, Deep, and UltraDeep layers covers about 108, 26, and 4 square degrees down to depths of i ∼ 26.4, ∼ 26.5, and ∼ 27.0 mag, respectively (5σ for point sources). All the layers are observed in five broad bands (grizy), and the Deep and UltraDeep layers are observed in narrow bands as well. We achieve an impressive image quality of 0.6 arcsec in the i-band in the Wide layer. We show that we achieve 1 − 2 per cent PSF photometry (rms) both internally and externally (against Pan-STARRS1), and ∼ 10 mas and 40 mas internal and external astrometric accuracy, respectively. Both the calibrated images and catalogs are made available to the community through dedicated user interfaces and database servers. In addition to the pipeline products, we also provide value-added products such as photometric redshifts and a collection of public spectroscopic redshifts. Detailed descriptions of all the data can be found online. The data release website is https://***. Copyright © 2017, The Authors. All rights reserved.

We present a calculation of the form factors of the D→Klν and D→πlν semileptonic decays at zero momentum transfer, ultimately for the purpose of determining the Cabibbo-Kobayashi- Maskawa (CKM) matrix elements |Vcs| and |Vcd |. This work uses MILC Nf = 2+1+1 configurations with the HISQ action for both sea quarks and valence quarks, including several physical mass ensembles and lattice spacings down to 0.042 fm. The calculation is done directly at q2 = 0 by employing twisted boundary conditions to tune the child particle momenta. Results at the physical point and in the continuum limit will be achieved in the final analysis through the use of Heavy-Meson Staggered cPT. Here we present our expected error budget and compare with the error of prior calculations. © Copyright owned by the author(s).

Due to unique physiochemical properties of carbon nanotubes (CNTs), they are utilized in biomedicine applications including biomedical engineering, tissue engineering, drug delivery, gene therapy and biosensor engineering. Studies have been shown that carbon nanotube have a large propensity to interact with biomembranes; therefore, the toxicity of these nanomaterials and understanding the way CNTs interact with cell become more important. Recently, enormous efforts have been made to understand the molecular mechanism of CNTs and lipid bilayer interaction. Because of the relative large scale of lipid bilayer, quantum ab-initio methods are not common for such systems; consequently, both all atom and coarse grained molecular dynamic simulation (MD) are widely performed. For simulation of such system it is important to apply the correct physical and structural properties of carbon nanotube in the simulation, for instance with density functional theory (DFT) modeling it has been clear that, for open-ended CNTs not only is there unsaturated bonds at the end of tube, but also has a significant dipole moment which should not neglected and their quantity correspond to nanotube chirality and diameter. The aim of this work is to discuss the partial charges distribution along the carbon nanotubes and describe how they affect in CNTs -lipid bilayer interaction by free energy calculation. Our Simulation consist of two stage, first partial charges for pristine and functional carbon nanotube were determined by DFT calculation then results were applied to molecular dynamic force field. The DFT simulation computes partial charges quantity at the ends of nanotube and its results indicate that partial charges for functional nanotubes are higher than pristine nanotubes. The MD simulation determines that nanotubes interaction energy with biomembrane is highly strong, about 120 kcal/mol.

This paper deals with the large deflection of rigid-plastic structural members subjected to intense dynamic loads, such as explosive pressure and impact loadings. From the viewpoint of energy equilibrium, a theoretical procedure called the Membrane Factor Method was proposed by the authors in analyzing the dynamic plastic response of beams and plates with deflections in the range where both bending moments and membrane forces are of significance. The Membrane Factor Method is generalized and elaborated and its applications to various cases of dynamically loaded beams and plates are surveyed, with the expressions of the modifying membrane factors in each case being summarized and discussed. It is seen from comparison that the predictions by this method on the final deflections of beams and plates agree well with the corresponding experimental results for deflections up to 5-10 times of thickness. This procedure greatly improves the estimates from the bending-only theory and provides feasible complete response analyses, whose predictions are much more reliable than modal approximations. © 2014 WIT Press.

In the framework of quantum chromodynamics (QCD), parton distribution functions (PDFs) quantify how the momentum and spin of a hadron are divided among its quark and gluon constituents. Two main approaches exist to determine PDFs. The first approach, based on QCD factorization theorems, realizes a QCD analysis of a suitable set of hard-scattering measurements, often using a variety of hadronic observables. The second approach, based on first-principle operator definitions of PDFs, uses lattice QCD to compute directly some PDF-related quantities, such as their moments. Motivated by recent progress in both approaches, in this document we present an overview of lattice-QCD and globalanalysis techniques used to determine unpolarized and polarized proton PDFs and their moments. We provide benchmark numbers to validate present and future lattice-QCD calculations and we illustrate how they could be used to reduce the PDF uncertainties in current unpolarized and polarized global analyses. This document represents a first step towards establishing a common language between the two communities, to foster dialogue and to further improve our knowledge of PDFs.
