Size scaling of strength in thin film delamination
, 2011 We investigate by numerical simulation the system size dependence of the shear delamination strength of thin elastic films. The films are connected to a rigid substrate by a disordered interface containing a pre-existing crack. The size dependence of the

Concentrations and snow-atmosphere fluxes of reactive nitrogen at Summit, Greenland [PDF]
, 1999 Concentrations and fluxes of NOy (total reactive nitrogen), ozone concentrations and fluxes of sensible heat, water vapor, and momentum were measured from May 1 to July 20, 1995 at Summit, Greenland. Median NOy concentrations declined from 947 ppt in May

Influence of Microstructure on Mechanical Properties of Snow
Defence Science Journal, 1995 Snow, being composed of ice grains of varying shapes, sizes, orientations, etc., has been treated as a particulate material. The mechanical properties of snow have been described in terms of microstructural parameters. A set of variables, which characterise the microstructure of snow at the granular level, has been chosen and quantified following ...

Testing the Strength of Buried Surface Hoar Weak Layers Under Combined Compression and Shear Loading
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract We experimentally determined the multiaxial strength of weak layers of buried surface hoar using displacement‐controlled tests under combined normal and shear loading on a custom testing machine. We tested 63 samples from three different weak layers, with strengths ranging from 1 to 10 kPa with considerable scattering. While shear strength was

On the Influence of Mineral Dust on Glacial Albedo at Nevado Huascarán (Cordillera Blanca, Peru)
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.Abstract In addition to warming and hydrological changes, glacier retreat is influenced by mineral dust and other light absorbing impurities. However, very little is known about the presence of mineral dust in the tropical Andes, making it difficult to model the radiative impact of dust on glacial surfaces.

Simulation of current transients through ultrathin gate oxides during plasma etching [PDF]
, 1997 Monte Carlo simulations of electron tunneling through a 3 nm gate oxide during etching of dense patterns of gate electrodes in uniform high-density plasmas reveal two current transients, which occur: (a) when the open area clears, and (b) when the ...
