conclusions the x-intercepts (point at which the fdc crosses the x-axis) were on average more in the base-in direction, y-intercepts (point at which the fdc crosses the y-axis) were shifted in the exo direction, and slopes were steeper in the symptomatic group. results there were more subjects with exo fixation disparity than eso fixation disparity in the study sample. the means for fixation di...

Several indices based on the receiver operating characteristic curve (ROC curve) have previously been found to possess probabilistic interpretations. However, these interpretations are based on some unrealistic diagnostic scenarios. In this paper, the author presents a new approach using the Lorenz curve. The author found that the summary indices of the Lorenz curve, that is, the Pietra index a...

Some important areas use more and more piezoelectric force test systems, due to their high sensitivity and natural frequency. To study the dynamic testing performance of the system in the conditions of high natural frequency, one of the effective methods is establishing the mathematical model of dynamic response of test system. By improving specific algorithm of the conventional nonlinear modal...

BACKGROUND The minimally invasive Oxford unicompartmental knee arthroplasty (UKA) is a demanding procedure but has many advantages compared with total knee arthroplasty (TKA). The aim of this observational study was to investigate the learning curve of one experienced surgeon introducing minimally invasive Oxford phase 3 UKA into his routine clinical practice. METHODS The first 50 consecutive...

v. dannon showed that spherical curves in e4 can be given by frenet-like equations, and he thengave an integral characterization for spherical curves in e4 . in this paper, lorentzian spherical timelike andspacelike curves in the space time 41 r are shown to be given by frenet-like equations of timelike andspacelike curves in the euclidean space e3 and the minkowski 3-space 31 r . thus, finding...
