Decay of the Kolmogorov N-width for wave problems [PDF]

open access: yesApplied Mathematics Letters, 2019
The Kolmogorov N -width d N ( M ) describes the rate of the worst-case error (w.r.t. a subset M ⊂ H of a normed space H ) arising from a projection onto the best-possible linear subspace of H of dimension N ∈ N .

Subsonic and intersonic shear rupture of weak planes with a velocity weakening cohesive zone [PDF]

open access: yes, 2002
A substantial effort has been devoted in the past toward modeling earthquake source mechanisms as dynamically extending shear cracks. Most of the attention was focused on the subsonic crack speed regime. Recently, a number of reports have appeared in the

Half-plane partial slip contact problems with a constant normal load subject to a shear force and differential bulk tension [PDF]

open access: yes, 2018
This article provides a new form of solution to half-plane contact problems in partial slip where a normal load has been applied, held constant and is subsequently loaded with both a shear force and differential bulk tension.

What sets river width?

open access: yesScience Advances, 2020
The width of river channels is controlled by the resistance to erosion of the most difficult to erode material lining the channel. One of the simplest questions in riverine science remains unanswered: “What determines the width of rivers?” While myriad ...
