[1] We use limb profiles to quantify the long‐wavelength topography of the Saturnian satellites. The degree 2 shapes of Mimas, Enceladus, and Tethys are not consistent with hydrostatic equilibrium. We derive 2‐D topographic maps out to spherical harmonic degree 8. There is a good correlation with topography derived from stereo techniques. If uncompensated, topography at degree 3 and higher is l...

OBJECTIVES This study was designed to identify common HIV-1 mutation complexes affecting the slope of inhibition curve, and to propose a new parameter incorporating both the IC50 and the slope to evaluate phenotypic resistance. METHODS Utilizing site-directed mutagenesis, we constructed 22 HIV-1 common mutation complexes. IC50 and slope of 10 representative approved drugs and a novel agent ag...

Anterior cruciate ligament (ACL) is the primary stabilizer of the knee. An impairment of any of the dynamic or static stability providing factors can lead to overload on the other factors and ultimately to deterioration of knee stability. This can result in anterior tibial translation and rupture of the ACL. The purpose of this study was to examine the influence of tibial slope on ACL injury ri...

The habitat characteristics of Torreya were investigated based on high resolution DEM and remote sensing image. The distribution of Torreya was mapped by visual interpretation of IKONOS image. The landform and PCA analysis results showed that curvature, altitude, aspect and slope were found to be the dominant features controlling spatial distribution pattern of Torreya. A certain degree moistur...

Let X/Fp be an Artin-Schreier curve defined by the affine equation yp−y = f̃(x) where f̃(x) ∈ Fp[x] is monic of degree d. In this paper we develop a method for estimating the first slope of the Newton polygon of X. Denote this first slope by NP1(X/Fp)). We use our method to prove that if p > d ≥ 2 then NP1(X/Fp) ≥ d p−1 d e p−1 . If p > 2d ≥ 4, we give a sufficient condition for the equality to h...

This article studied the effects of resolution on elevation and slope using Statistical and Geostatistical methods. Xian' Nan watershed in Loess Plateau was taking as the study area. The base data was a 1:10000 topographic map and the resolutions studied in this paper included 5 m, 25 m and 50 m. The results showed that: (1) for elevation and slope data, the mean value, STD value, histogram and...

Rainfall infiltration exerts great effect on the stability of soil slopes. Based on the actual rainfall data, saturated-unsaturated seepage theory and the mechanical theory of unsaturated porous media, numerical simulations were conducted to examine the seepage field of saturatedunsaturated slope during rainfall infiltration in this paper. The influence of the coefficient with rainfall duration...

The problem for assessment of dose proportionality (or linearity) is studied. Various methods for assessment of dose proportionality (or linearity) such as ANOVA type F-test have been proposed. Cheng et al. (2006) proposed an alternative approach based on the slopes of adjacent dose levels under a crossover design. They showed that when dose proportionality (or linearity) cannot be established,...

The two-branched inflow of warm and saline Atlantic Water to the Arctic is the major contributor of oceanic heat to the Arctic climate system. However, while the Atlantic Water entering the Arctic through the Fram Strait retains a large part of its heat as it flows along the Arctic continental slope, the branch flowing through the shallow Barents Sea releases a substantial amount of heat to the...

The evaluation of seismic slope performance during earthquakes is important, because the failure of slope (such as an earth dam, natural slope, or constructed earth embankment) can result in significant financial losses and human. It is important, therefore, to be able to forecast such displacements induced by earthquake. However, the traditional forecasting methods, such as empirical formulae,...
