The Coulomb dissociation (CD) of 8B has emerged as a landmark testing ground of the very method of CD for measuring the cross section of the low-energy 7Be(p, γ )8B direct capture (DC) reaction. Recent claims of evidence of slope difference between CD and DC results are critically examined. We include all relevant RIKEN2 data and all previously published DC data, and we examine the extracted so...

The change of physical and mechanical properties slope rock mass in open-pit mines seasonally frozen area under the action freeze–thaw cycles is one main reasons for instability. In this paper, taking parameters coal seam sandstone layer Beitashan Pasture Open-Pit Mine Xinjiang as research object, considering combined effect frost-heave tensile stress crack perpendicular to surface three-dimens...

The slope instability brought on by earthquakes frequently results in significant property damage and casualties. At present, the research displacement response of a under earthquake has mainly emphasized action mainshock, without accounting for impact an aftershock, spatial variability material parameters is often neglected. fully accounted this paper, dynamic reliability permanent (DP) produc...

This paper aims to propose a bootstrap method for characterizing the effect of uncertainty in shear strength parameters on slope reliability. The procedure for a traditional slope reliability analysis with fixed distributions of shear strength parameters is presented first. Then, the variations of the mean and standard deviation of shear strength parameters and the Akaike Information Criterion ...

This work considers the effects of the Hurst exponent (H) on the local electric field distribution and the slope of the Fowler-Nordheim (FN) plot when considering the cold field electron emission properties of rough Large-Area Conducting Field Emitter Surfaces (LACFESs). A LACFES is represented by a self-affine Weierstrass-Mandelbrot function in a given spatial direction. For 0.1 ≤ H < 0.5, the...

1. Principle and computation of Sacin and Scond from phaseIII slope analysis : The MBW normalized slope analysis technique identifies the various mechanisms of ventilation heterogeneity generating a phaseIII slope, attributing these to either the conductive airways (where convection predominates) or the acinar air spaces (where diffusion and convection interact). In the conductive lung zone, a ...
