The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe

Kavli Affiliate: Mark Vagins | Summary:The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay — these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our Universe, […]

Software Engineering Process Theory: A Multi-Method Comparison of Sensemaking-CoevoIution-Implementation Theory and Function-Behavior-Structure Theory

Kavli Affiliate: Daniel Ralph| First 5 Authors: Paul Ralph, Paul Ralph, , , | Summary:Many academics have called for increasing attention to theory in software engineering. Consequently, this paper empirically evaluates two dissimilar software development process theories – one expressing a more traditional, methodical view (FBS) and one expressing an alternative, more improvisational view (SCI). […]

Physical Principles for Scalable Neural Recording

Kavli Affiliate: Mikhail Shapiro | Summary:Simultaneously measuring the activities of all neurons in a mammalian brain at millisecond resolution is a challenge beyond the limits of existing techniques in neuroscience. Entirely new approaches may be required, motivating an analysis of the fundamental physical constraints on the problem. We outline the physical principles governing brain activity […]

Observing the Next Galactic Supernova

Kavli Affiliate: Mark Vagins | Summary:We model the distance, extinction, and magnitude probability distributions of a successful Galactic core-collapse supernova (ccSN), its shock breakout radiation, and its massive star progenitor. We find, at very high probability (~100%), that the next Galactic SN will easily be detectable in the near-IR and that near-IR photometry of the […]

A Decade-Baseline Study of the Plasma States of Ejecta Knots in Cassiopeia A

Kavli Affiliate: Sarah N. T. Heine | Summary:We present the analysis of 21 bright X-ray knots in the Cassiopeia A supernova remnant from observations spanning 10 yr. We performed a comprehensive set of measurements to reveal the kinematic and thermal state of the plasma in each knot, using a combined analysis of two high energy […]

Elliptic genera of two-dimensional N=2 gauge theories with rank-one gauge groups

Kavli Affiliate: Kentaro Hori | Summary:We compute the elliptic genera of two-dimensional N=(2,2) and N=(0,2) gauged linear sigma models via supersymmetric localization, for rank-one gauge groups. The elliptic genus is expressed as a sum over residues of a meromorphic function whose argument is the holonomy of the gauge field along both the spatial and the […]

The Expected Linkage Disequilibrium in Finite Populations Revisited

Kavli Affiliate: Christopher Ober| First 5 Authors: Ulrike Ober, Ulrike Ober, , , | Summary:The expected level of linkage disequilibrium (LD) in a finite ideal population at equilibrium is of relevance for many applications in population and quantitative genetics. Several recursion formulae have been proposed during the last decades, whose derivations mostly contain heuristic parts […]

Evidence of Electron Neutrino Appearance in a Muon Neutrino Beam

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 […]

The Illusion of Requirements in Software Development

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 […]

Application of machine learning algorithms to the study of noise artifacts in gravitational-wave data

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 […]
