In this paper we describe a new algorithm for nonrigid registration of brain images based on an elastically deformable model. The use of registration methods has become an important tool for computer-assisted diagnosis and surgery. Our goal was to improve analysis in various applications of neurology and neurosurgery by improving nonrigid registration. A local gray level similarity measure is u...

We show that, for a utility function U : R→ R having reasonable asymptotic elasticity, the optimal investment process Ĥ ·S is a super-martingale under each equivalent martingale measure Q, such that E[V ( dP )] < ∞, where V is the conjugate function of U . Similar results for the special case of the exponential utility were recently obtained by Delbaen, Grandits, Rheinländer, Samperi, Schweizer...

This study uses a new data set which merges the Social Security earnings histories of parents and children in the 1984 Survey of Income and Program Participation to measure the intergenerational elasticity in earnings in the United States. Earlier studies that found an intergenerational elasticity of 0.4 have typically used only five year averages of fathers’ earnings to measure fathers’ perman...

A weak formulation of the stress boundary conditions in Continuum Mechanics is proposed. This condition has the form of a balance law, allows also singular measure data and is consistent with the regular case. An application to the Flamant solution in linear elasticity is shown.

In this talk I assert that the usual interpretation of what one means by “elasticity” is much too insular and illustrate my thesis by introducing implicit constitutive theories that can describe the nondissipative response of solids. I show that response which was hitherto untenable within the context of Cauchy or Green Elasticity are not only possible, they can explain phenomena that have thus...

Building a new power system with renewable energy as its main component is key measure proposed by China to address the climate change problem. Strengthening demand-side management (DSM) an important way promote development of system. As economic incentive in DSM, current TOU tariff faced problem weak effect due small difference between peak and valley periods. Against this background, novel hy...

BACKGROUND Achilles tendon injuries are one of the most common tendon injuries. Surgical treatment is preferred in young and active patients. Although there are studies which evaluate the repair area with magnetic resonance imaging and ultrasonography after surgical treatment, there are very few studies which analyzes the elasticity of the tendon by quantitative methods. ARFI (acoustic radiatio...

AIMS/INTRODUCTION To measure the elasticity of the tibial nerve using sonoelastography, and to associate it with diabetic neuropathy severity, the cross-sectional area of the tibial nerve and neurophysiological findings in type 2 diabetic patients. MATERIALS AND METHODS The elasticity of the tibial nerve was measured as the tibial nerve:acoustic coupler strain ratio using high-resolution ultr...
