Background: Evaluating the landmarks for rotation of the distal femur is a challenge for orthopedic surgeons. Although the posterior femoral condyle axis is a good landmark for surgeons, the surgical transepicondylar axis may be a better option with the help of preoperative CT scanning. The purpose of this study was to ascertain relationships among the axes’ guiding distal femur rotational ...

introduction : comorbidity is a new term in psychiatric nosology which despite its expansive use is not clearly defined. overlapping of axis i and axis ii disorders in multiaxial system of dsm and controversy over which disorders belong to which axis, have also complicated the issue. a number of studies investigating patterns of comorbidity for axis i and axis ii disorders could not find a one ...

Deligeorgis, D., Yannakos, D., and Doxiadis, S. (1973). Archives of Disease in Childhood, 48, 790. Normal size ofliver in infancy and childhood: x-ray study. The longest vertical distance between the upper and lower borders of the liver measured radiologically is suggested for estimating the size of the liver. This parameter, called vertical axis of the liver, was measured in 350 healthy infant...

Recent reports have shown that saccades can deviate either toward or away from distractors. However, the specific conditions responsible for the change in initial saccade direction are not known. One possibility, examined here, is that the direction of curvature (toward or away from distractors) reflects preparatory tuning of the oculomotor system when the location of the target and distractor ...

The vertebrate A-P axis is a time axis. The head is made first and more and more posterior levels are made at later and later stages. This is different to the situation in most other animals, for example, in Drosophila. Central to this timing is Hox temporal collinearity (see below). This occurs rarely in the animal kingdom but is characteristic of vertebrates and is used to generate the primar...

time axis could be detected. Hence, one concludes that if the deformation introduced changes in the elastic constants C33 or C44 these changes must be less than one or two percent for strains up to 10—' radian. Such a result is to be expected since the appearance of slip bands on the surface indicates that the deformation was confined to numerous very narrow bands. Within these bands one might ...

Graph drawing algorithms based on minimizing the so-called stress energy strive to place nodes in accordance with target distances. They were first introduced to the graph drawing field by Kamada and Kawai [11], and they had previously been used to visualize general kinds of data by multidimensional scaling. In this paper we suggest a novel algorithm for the minimization of the Stress energy. U...
