Margin Failures in Crown-Like Brittle Structures: Off-Axis Loading

June 11, 2007
Author(s)
Chris Ford, T Qasim, M T. Bush, X Z. Hu, Mahek Shah, Vibhu Saxena, Brian R. Lawn
The effect of off-axis loading of compliant indenters on the initiation of cracks at the margins of dental crown-like dome structures consisting of glass shells back-filled with an epoxy resin is examined. As in previous studies on similar structures but

Three-dimensional nature 1 of anomalous Hall conductivity in YMn6Sn6-xGax, x ? 0.55

November 19, 2024
Author(s)
Albert Davydov, Hari "Bhandari ", Zhenhua Ning, Po-Hao Chang, Peter Siegfried, Resham Regmi, Mohamed El Gazzah, Allen Oliver, Liqin Ke, Igor Mazin, Nirmal Ghimire
The unique connectivity of kagome lattices gives rise to topological properties such as flat bands and Dirac cones. When combined with ferromagnetism and with the chemical potential near the 2D Dirac points, this structure offers potential for realizing

The complete sequence of a human Y chromosome

August 23, 2023
Author(s)
Arang Rhie, Sergey Nurk, Monika Cechova, Savannah Hoyt, Dylan Taylor, Nathanael David Olson, Justin Zook, Adam Phillippy
The human Y chromosome has been notoriously difficult to sequence and assemble because of its complex repeat structure that includes long palindromes, tandem repeats and segmental duplications1,2,3. As a result, more than half of the Y chromosome is

Spectrum and Energy Levels of Five-Times Ionized Zirconium (Zr VI)

January 5, 2016
Author(s)
Joseph Reader, Mark D. Lindsay
The spectrum of five-times-ionized zirconium Zr VI was observed from 160 Å to 2000 Å with sliding spark discharges on 10.7-m normal- and grazing-incidence spectrographs. The existing analysis of this spectrum [Khan Z. A. et al. 1985 Phys. Scr. 31 837] was
