An analytic calculation of the surface current and selected mound angle is presented for the case of irreversible epitaxial growth on an fcc 111 surface with a finite Ehrlich-Schwoebel ES barrier. The special cases of short terraces and combinations of short terraces with facets which lead to large mound slopes are also discussed. We find that for both A and B steps the surface current and sele...

today's, adverse effects of off-site erosion, namely damages received from sediment, is a serious bioenvironmental problem. one of the methods for temporary soil stabilization before permanent rehabilitation of vegetation cover, especially on slopes, for mitigating of bioenvironmental contaminants, is using materials having property to cementate the dispersed particles on the soil surface....

Abstract Rock slopes with intermittent joints in open-pit mines are complex geological bodies composed of intact rock and discontinuous structural planes, their stability analysis necessary for mine disaster prevention. In this study, a series base friction tests were performed to determine the failure process displacement field evolution using speckle technique noncontact measurement system. N...

Using the Hatcher–Oertel algorithm for finding boundary slopes of Montesinos knots, we prove the Slope Conjecture and the Strong Slope Conjecture for a family of 3-tangle pretzel knots. More precisely, we prove that the maximal degrees of the colored Jones polynomial of such a knot determine a boundary slope as predicted by the Slope Conjecture, and that the linear terms in the degrees correspo...

Motivation: it would be great if we could understand the p-adic variation of the Up-eigenvalues of modular forms as the weights and/or levels varied. (More generally, it would be really great if we could understand how the local p-adic Galois representations attached to automorphic forms behave – for example, even very weak “equidistribution” results here would presumably imply very strong auto...

We show that for certain hyperbolic manifolds all boundary slopes are slopes of π1-injective immersed surfaces, covered by incompressible embeddings in some finite cover. The manifolds include hyperbolic punctured torus bundles and hyperbolic two-bridge knots.

Introduction The field of cell-death research has matured since pioneering discoveries showed that apoptosis is regulated genetically. Although many of the core caspase-signalling pathways are known, some of the most basic aspects of the biochemistry of mitochondrial apoptosis induction have remained elusive and are, in certain cases, controversial. Research on the metabolic dysfunction that oc...

Although water vapor is the most important greenhouse gas, it is not even agreed whether an increase in its concentration due to global warming will cause more warming or cooling. Warming (a positive feedback) will occur if the biggest effect is to absorb more outgoing long-wave radiation. Cooling (a negative feedback) will occur if the major result is to form more clouds, which would reflect m...

this paper addresses the validity of two hypotheses concerning changes of vowel quality in persian. the theory of centralization claims that there is a strong correlation between vowel duration and vowel quality. as vowel duration is shortened in unstressed contexts, the size of the vowel inventory reduces toward the center, leading to considerable overlap between different categories and a red...

Abstract. The warming and subsequent degradation of mountain permafrost within alpine areas represent an important process influencing the stability steep slopes rock faces. unstable monitored Mannen (Møre Romsdal county, southern Norway) Gámanjunni-3 (Troms Finnmark northern were classified as high-risk sites by Norwegian Geological Survey (NGU). Failure initiation has been suggested to be lin...
