The influence of root reinforcement on shallow landsliding has been well established through mechanistic and empirical studies, yet few studies have examined how local vegetative patterns influence slope stability. Because root networks spread outward from trees, the species, size, and spacing of trees should influence the spatial distribution of root strength. We documented the distribution an...

In many countries, slope failure is a complex natural issue that can result in serious hazards, such as landslide dams. It associated with the challenge of stability evaluation, which involves classification problem slopes and regression predicting factor safety (FOS) value. This study explored implementation machine learning to analyze using comprehensive database 880 homogenous (266 unstable ...

Let X be a norm curve in the SL(2,C)-character variety of a knot exterior M . Let t = ‖β‖/‖α‖ be the ratio of the Culler-Shalen norms of two distinct non-zero classes α, β ∈ H1(∂M,Z). We demonstrate that either X has exactly two associated strict boundary slopes ±t, or else there are strict boundary slopes r1 and r2 with |r1| > t and |r2| < t. As a consequence, we show that there are strict bou...

Prospective control of walking and running requires perceiving sloping surfaces that can and cannot support these activities. Two experiments on slant perception were conducted, motivated by the notion of geographical slant rather than optical slant, and by an affordance based description of surface layout. In Experiment 1, participants standing on a horizontal surface (the ground) adjusted the...

Among hemodialysis patients, the assessment of dry weight remains a matter of clinical judgment because tests to assess dry weight have not been validated. The objective of this study was to evaluate and validate relative plasma volume (RPV) monitoring as a marker of dry weight. We performed RPV monitoring using the Crit-Line monitor at baseline and at 8 weeks in 150 patients participating in t...

Three experiments investigated whether 14- and 15-month-old infants use information for both friction and slant for prospective control of locomotion down slopes. In Experiment 1, high- and low-friction conditions were interleaved on a range of shallow and steep slopes. In Experiment 2, friction conditions were blocked. In Experiment 3, the low-friction surface was visually distinct from the su...

unstable angina has progressive process and even in rest time, it happens frequently. it is a serious situation and 15-20 percent of patients are dying in duration of one year. treatment: patients often hospitalized because observation of their reactions to treatment is easier in hospital. treatment plan must be explain for them carefully. when patient’s situation due to anxiety is critical, be...

Helga Kuhse and Peter Singer recently examined the view expressed by John Lorber that whereas at times it is permissible to allow severely handicapped infants to die, killing them must never be allowed. In attempting to demonstrate the mistaken nature of Lorber's fear that allowing active infanticide would lead us onto a slippery slope Kuhse and Singer make much use of John Harris's paper in th...

How to construct a digitization of a straight line and be able to recognize a straight line in a set of pixels are very important topics in computer graphics. The aim of the present paper is to give a mathematically exact and consistent description of digital straight lines according to Rosenfeld’s definition. The digitizations of the lines with slopes 0 < a < 1, where a is irrational, are cons...

The slope-number of a graph G is the minimum number of distinct edge slopes in a straight-line drawing of G in the plane. We prove that for ∆ ≥ 5 and all large n, there is a ∆-regular n-vertex graph with slope-number at least n1− 8+ε ∆+4 . This is the best known lower bound on the slope-number of a graph with bounded degree. We prove upper and lower bounds on the slope-number of complete bipart...
