Abstract We present JWST near-infrared (NIR) and mid-infrared (MIR) spectroscopic observations of the nearby normal Type Ia supernova (SN) SN 2021aefx in nebular phase at +255 days past maximum light. Our Near Infrared Spectrograph (NIRSpec) Mid Instrument observations, combined with ground-based optical data from South African Large Telescope, constitute first complete optical+NIR+MIR spectrum covering 0.3–14 μ m. This unveils previously unobserved 2.5−5 m region, revealing strong iron...
Thermodynamical explosions of White Dwarfs (WD)are one the keys to high precision cosmology. Nebular spectra, namely mid-infrared (MIR) with JWST are an effective tool probe for multi-dimensional imprints explosion physics WDs and their progenitor systems but also pose a challenge simulations. What we observe as SNe Ia low-energy photons, light curves, spectra detected some days years after explosion. The is emitted from rapidly expanding envelope consisting low-density low-temperature...
Abstract We present and analyze a near-infrared (NIR) spectrum of the underluminous Type Ia supernova SN 2020qxp/ASASSN-20jq obtained with NIRES at Keck Observatory, 191 days after B -band maximum. The is dominated by number broad emission features, including [Fe ii ] 1.644 μ m, which highly asymmetric tilted top peak redshifted ≈2000 km s −1 . In comparison 2D non-LTE synthetic spectra computed from 3D simulations off-center delayed-detonation Chandrasekhar-mass ( M ch ) white dwarf (WD)...
Pedestrian accident data, recorded in general police procedure N.S.W., have been analysed for the one year, 1968. Whilst pedestrians were involved only 5.5% of all reported accidents, they contributed 13.5% those injured and 24% fatalities. An analysis some factors has shown that when a pedestrian is struck by car, he or she will receive on average two injuries. These injuries most likely be to limbs, especially legs, head: 1 out 20 cases these prove fatal. It also incidence fatality rises...
I take 'informal logic' to be the (descriptive and normative) study of 'real arguments'-arguments which are or have been used with aim convincing others a point view. argue that informal logic tradition thus conceived (i) lends strong support something like Quine's view our beliefs really one another filaments in spider's web--and traditional implication is an asymmetric relation false; (ii) suggests classic division arguments into deductive inductive has distorted thinking about evaluation...
Although methods of evaluating the effect glare on ability an observer to detect objects in terms equivalent veiling luminance (e.v.l.) were developed by Holladay and Stiles prior 1930 their results have usually been interpreted Britain as indicating that disability is negligible lighted streets. A re-examination this question indicates important erroneous conclusions may be reached if neglected when calculating revealing power. For example power non-cut-off lighting installations rated...

Previous studies suggest that the use of dipped headlights on urban traffio routes lit by street lighting is undesirable because glare, yet it often contended present marker lights are not adequately conspicuous. An investigation was therefore carried out, using appraisal techniques, to determine intensity vehicle front which will be conspicuous without being too bright. It found requirements were largely independent observer attributes, luminance road surface and its surrounds number...
COMPANION papers present some of the inherent possibilities and useful applications for dynamoelectric amplifiers. <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1,2</sup> They have also clearly pointed out that value such an amplifier is determined by three characteristics: (1) ratio response or sensitivity; (2) speed response; (3) stability.
