TL;DR: In this article, an elastic modulus decrease of 49 and 64 GPa upon C- and Al-vacancy formation, respectively, was predicted and experimentally verified and is caused by concomitant weakening in average bond energy.

Abstract: The distribution of galaxies within the local universe is characterized by anisotropic features. Observatories searching for the production sites of astrophysical neutrinos can take advantage of these features to establish directional correlations between a neutrino dataset and overdensities in the galaxy distribution in the sky. The results of two correlation searches between a seven-year time-integrated neutrino dataset from the IceCube Neutrino Observatory, and the 2MASS Redshift Survey (2MRS) catalog are presented here. The first analysis searches for neutrinos produced via interactions between diffuse intergalactic Ultra-High Energy Cosmic Rays (UHECRs) and the matter contained within galaxies. The second analysis searches for low-luminosity sources within the local universe, which would produce subthreshold multiplets in the IceCube dataset that directionally correlate with galaxy distribution. No significant correlations were observed in either analyses. Constraints are presented on the flux of neutrinos originating within the local universe through diffuse intergalactic UHECR interactions, as well as on the density of standard candle sources of neutrinos at low luminosities.

TL;DR: In this article , the authors used a segmented TiB2-AlB2 target using Ar and Kr as sputtering gas to deposit understoichiometric diboride coatings.

TL;DR: In this paper, thin BCN films were deposited by plasma enhanced chemical vapor deposition (PECVD) using chloridic precursors, and a correlation between film composition and precursor species concentration in the plasma was established.

TL;DR: In this article, the authors proposed principles for the design of tough and stiff metallic glasses based on an ab initio model for metallic glasses in conjunction with an experimental high-throughput methodology geared towards revealing the relationship between chemistry, topology and mechanical properties.
