Experiments have been conducted with 6.25 mm diameter tungsten rods striking concrete at 2.2 km/s. Three concretes were used—one was 2.35 g/cm 3 and the other two were 2.27 g/cm 3 . The erosion rates were measured to be T /Δ L = 2.4–3.1 dependin

Recently, an efficient, numerically robust algorithm for calculating acoustic normal modes called MODELAB was implemented [J. Acoust. Soc. Am. 97, 1576–1585 (1995)]. In this paper, a new approach is introduced and shown to significantly reduce the

An efficient, numerically robust algorithm for calculating acoustic normal modes in a fluid, layered ocean environment is described. Each layer is assumed to have a sound‐speed profile for which the mode functions may be expressed analytically in t

Behind-armor debris that results from tungsten rods penetrating armor steel at 2 km/s was studied by analysis of recovered fragments. Fragment recovery was by means of particle board. Individual fragments were analyzed by x-ray tomography, which prov

BACKGROUND/OBJECTIVE: Variants in the interleukin-23 receptor (IL23R) and the autophagy-related 16-like 1 (ATG16L1) genes have been associated with an increased risk of Crohn’s disease (CD). Both genes were identified through genome-wide associatio
