abstract the prediction of active earth pressures is essential to the design of retaining walls in case of reinforced and unreinforced soils. in this study, a new analytical method is presented to determine the coefficient of earth pressure. the horizontal slice method is used to compute the active earth pressure behind a rigid retaining wall in consideration of the granular soils. to verify th...

Research on synaptically-released zinc is frequently done in vitro with acute brain slice preparations. We show here the in vitro hippocampal slice preparation has two major pitfalls for zinc research. First, up to 50% of the synaptic zinc is lost during slice cutting and/or the first 10 min of slice incubation, with the losses being most pronounced on the edges of the slice. Second, the releas...

Introduction Subject motion in functional magnetic resonance imaging (fMRI) is highly problematic for the detection of responses showing small effect size and/or spatially extent. To mitigate this problem, various methods have been proposed to correct this type of motion a posteriori. These methods correct each volume using a 3D rigid-body matrix having six parameters for translation and rotati...

This paper outlines the basic steps in the design and implementation of a feature based Transmission Electron Microscopy (TEM) image registration application and highlights some of the implementation details, such as the detection of features, feature descriptor design, robust filtering of mismatched descriptors, and transform estimation. Although the approach chosen is based on the Scale Invar...

AIM To observe the effect of targeted therapy with 64-slice spiral computed tomography (CT) combined with cryoablation for liver cancer. METHODS A total of 124 patients (142 tumors) were enrolled into this study. According to the use of dual-slice spiral CT or 64-slice spiral CT as a guide technology, patients were divided into two groups: dual-slice group (n = 56, 65 tumors) and 64-slice gro...

This paper presents a method based on shape-context and statistical measures to match interventional 2D Trans Rectal Ultrasound (TRUS) slice during prostate biopsy to a 2D Magnetic Resonance (MR) slice of a pre-acquired prostate volume. Accurate biopsy tissue sampling requires translation of the MR slice information on the TRUS guided biopsy slice. However, this translation or fusion requires t...

Based on the bending deformation theory of cantilever beam, mathematical model single valve slice under uniform load is proposed and deduced by using microbeam element method (MEM). The accuracy reliability established MEM small deflection (SDM) are verified through finite simulation comparison. results show that suitable not only for (SDD) but also large (LDD) slice, can reflect dynamic charac...

We give a new geometric obstruction to the iterated Bing double of a knot being a slice link: for n > 1 the (n + 1)st iterated Bing double of a knot is rationally slice if and only if the nth iterated Bing double of the knot is rationally slice. The main technique of the proof is a covering link construction simplifying a given link. We prove certain similar geometric obstructions for n ≤ 1 as ...

A major advantage of hippocampal slice preparations is that the cytoarchitecture and synaptic circuits of the hippocampus are largely retained. In neurotoxicology research, organotypic hippocampal slices have mostly been used as acute ex vivo preparations for investigating the effects of neurotoxic chemicals on synaptic function. More recently, hippocampal slice cultures, which can be maintaine...
