Search for inelastic dark matter with the CDMS II experiment
CDMS Collaboration, Z. Ahmed, D. S. Akerib +63
Results are presented from a reanalysis of the entire five-tower data set acquired with the Cryogenic Dark Matter Search (CDMS II) experiment at the Soudan Underground Laboratory,…
Insights Into the High-Energy Gamma-ray Emission of Markarian 501 from Extensive Multifrequency Observations in the Fermi Era
LAT collaboration, A. A. Abdo et al., the MAGIC collaboration +6
We report on the gamma-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average LAT gamma-ray spectrum of Mrk 501 can be well descr…
Multi-wavelength Observations of the Flaring Gamma-ray Blazar 3C 66A in 2008 October
LAT collaboration, A. A. Abdo et al., the VERITAS collaboration +4
The BL Lacertae object 3C 66A was detected in a flaring state by the Fermi Large Area Telescope (LAT) and VERITAS in 2008 October. In addition to these gamma-ray observations, F-GA…
Results from a Low-Energy Analysis of the CDMS II Germanium Data
CDMS Collaboration, Z. Ahmed, D. S. Akerib +62
We report results from a reanalysis of data from the Cryogenic Dark Matter Search (CDMS II) experiment at the Soudan Underground Laboratory. Data taken between October 2006 and Sep…
Controlling the quantum stereodynamics of ultracold bimolecular reactions
M. H. G. de Miranda, A. Chotia, B. Neyenhuis +6
Chemical reaction rates often depend strongly on stereodynamics, namely the orientation and movement of molecules in three-dimensional space. An ultracold molecular gas, with a tem…
A Critical Path Approach to Analyzing Parallelism of Algorithmic Variants. Application to Cholesky Inversion
Henricus Bouwmeester, Julien Langou
Algorithms come with multiple variants which are obtained by changing the mathematical approach from which the algorithm is derived. These variants offer a wide spectrum of perform…
Low-threshold analysis of CDMS shallow-site data
CDMS Collaboration, D. S. Akerib, M. J. Attisha +45
Data taken during the final shallow-site run of the first tower of the Cryogenic Dark Matter Search (CDMS II) detectors have been reanalyzed with improved sensitivity to small ener…
Another look at the BL Lacertae flux and spectral variability
C. M. Raiteri, M. Villata, L. Bruschini +52
The GLAST-AGILE Support Program (GASP) of the Whole Earth Blazar Telescope (WEBT) monitored BL Lacertae in 2008-2009 at radio, near-IR, and optical frequencies. During this period,…
WRF-Fire Applied in Bulgaria
Nina Dobrinkova, Georgi Jordanov, Jan Mandel
WRF-Fire consists of the WRF (Weather Research and Forecasting Model) coupled with a fire spread model, based on the level-set method. We describe a preliminary application of WRF-…
The December 2009 gamma-ray flare of 3C 454.3: the multifrequency campaign
L. Pacciani, V. Vittorini, M. Tavani +81
During the month of December, 2009 the blazar 3C 454.3 became the brightest gamma-ray source in the sky, reaching a peak flux F ~2000E-8 ph/cm2/s for E > 100 MeV. Starting in Novem…
Limits on Superconductivity-Related Magnetization in SrRuO and PrOsSb from Scanning SQUID Microscopy
Clifford W. Hicks, John R. Kirtley, Thomas M. Lippman +6
We present scanning SQUID microscopy data on the superconductors Sr2RuO4 (Tc = 1.5 K) and PrOsSb (Tc = 1.8 K). In both of these materials, superconductivity-related time…
Data Driven Computing by the Morphing Fast Fourier Transform Ensemble Kalman Filter in Epidemic Spread Simulations
Jan Mandel, Jonathan D. Beezley, Loren Cobb +1
The FFT EnKF data assimilation method is proposed and applied to a stochastic cell simulation of an epidemic, based on the S-I-R spread model. The FFT EnKF combines spatial statist…
Computing the R of the QR factorization of tall and skinny matrices using MPI_Reduce
Julien Langou
A QR factorization of a tall and skinny matrix with n columns can be represented as a reduction. The operation used along the reduction tree has in input two n-by-n upper triangula…
Towards an Efficient Tile Matrix Inversion of Symmetric Positive Definite Matrices on Multicore Architectures
Emmanuel Agullo, Henricus Bouwmeester, Jack Dongarra +3
The algorithms in the current sequential numerical linear algebra libraries (e.g. LAPACK) do not parallelize well on multicore architectures. A new family of algorithms, the tile a…
Self-aligned nanoscale SQUID on a tip
Amit Finkler, Yehonathan Segev, Yuri Myasoedov +7
A nanometer-sized superconducting quantum interference device (nanoSQUID) is fabricated on the apex of a sharp quartz tip and integrated into a scanning SQUID microscope. A simple…
The solar photospheric abundance of carbon.Analysis of atomic carbon lines with the CO5BOLD solar model
E. Caffau, H. -G. Ludwig, P. Bonifacio +5
The use of hydrodynamical simulations, the selection of atomic data, and the computation of deviations from local thermodynamical equilibrium for the analysis of the solar spectra…
