Kavli Affiliate: Mark Hartz | Summary:The T2K collaboration: reports evidence for electron neutrino appearance at the atmospheric mass splitting, |Δm_32^2|=2.4×10^-3 eV^2. An excess of electron neutrino interactions over background is observed from a muon neutrino beam with a peak energy of 0.6 GeV at the Super-Kamiokande (SK) detector 295 km from the beam’s origin. Signal […]
Kavli Affiliate: Daniel Ralph| First 5 Authors: Paul Ralph, Paul Ralph, , , | Summary:It is widely accepted that understanding system requirements is important for software development project success. However, this paper presents two novel challenges to the requirements concept. First, where many plausible approaches to achieving a goal are evident, there may be insufficient […]
Kavli Affiliate: Erotokritos Katsavounidis | Summary:The sensitivity of searches for astrophysical transients in data from the LIGO is generally limited by the presence of transient, non-Gaussian noise artifacts, which occur at a high-enough rate such that accidental coincidence across multiple detectors is non-negligible. Furthermore, non-Gaussian noise artifacts typically dominate over the background contributed from stationary […]
Kavli Affiliate: Richard D. Robinson | Summary:In order to fully understand nanoscale heat transport it is necessary to spectrally characterize phonon transmission in nanostructures. Towards this goal we have developed a microfabricated phonon spectrometer. We utilize microfabricated superconducting tunnel junction-based (STJ) phonon transducers for the emission and detection of tunable, non-thermal, and spectrally resolved acoustic […]
Kavli Affiliate: Daniel Ralph| First 5 Authors: Paul Ralph, Paul Ralph, , , | Summary:The dominant view of design in information systems and software engineering, the Rational Design Paradigm, views software development as a methodical, plan-centered, approximately rational process of optimizing a design candidate for known constraints and objectives. This paper synthesizes an Alternative Design […]
Kavli Affiliate: E. P. S. Shellard | Summary:We describe the detection, interpretation, and removal of the signal resulting from interactions of high energy particles with the Planck High Frequency Instrument (HFI). There are two types of interactions: heating of the 0.1,K bolometer plate; and glitches in each detector time stream. The transient responses to detector […]
Kavli Affiliate: Toshitake Kohno | Summary:Let X be a finite CW-complex, denote its fundamental group by G. Let R be an n-dimensional complex repesentation of G. Any element A of the first cohomology group of X with complex coefficients gives rise to the exponential deformation of the representation R, which can be considered as a […]
Kavli Affiliate: Peter Michelson | Summary:We report on spectroscopic observations covering most of the 475 BL Lacs in the 2nd Fermi LAT catalog of AGN. Including archival measurements (correcting several erroneous literature values) we now have spectroscopic redshifts for 44% of the BL Lacs. We establish firm lower redshift limits via intervening absorption systems and […]
Kavli Affiliate: Jacqueline Barton| First 5 Authors: Judd D. Bowman, Judd D. Bowman, , , | Summary:Significant new opportunities for astrophysics and cosmology have been identified at low radio frequencies. The Murchison Widefield Array is the first telescope in the Southern Hemisphere designed specifically to explore the low-frequency astronomical sky between 80 and 300 MHz […]
Kavli Affiliate: John Belcher | Summary:We compare the nature of electromagnetic fields and of gravitational fields in linearized general relativity. We carry out this comparison both mathematically and visually. In particular the "lines of force" visualizations of electromagnetism are contrasted with the recently introduced tendex/vortex eigenline technique for visualizing gravitational fields. Specific solutions, visualizations, and […]
