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 ...

We present electron temperature (Te) maps for the edge-on system Mrk 1486, affording "direct-method" gas-phase metallicity measurements across 58 (4.1 kpc) along minor axis and 99 (6.9 major axis. These maps, enabled by strong detections of [O iii] λ4363 auroral emission line a large spatial extent reveal clear negative minor-axis Te gradient in which decreases with increasing distance from dis...

Altered functioning of the hypothalamic-pituitary-adrenal (HPA) axis is a robust correlate of major depression in adults, and to a lesser extent, in adolescents. Premorbid differences in HPA axis function have been found to prospectively predict the onset of adolescent depression. To what extent might our knowledge of HPA axis function in adolescents with, or at risk for, depression, help guide...

mulated concerning the study of left ventricular (LV) long axis function with different echocardiographic and Doppler techniques. The data pertain to LV systolic and diastolic function, valvular heart disease, detection of ischemia or myocardial viability, and prognosis and outcome of cardiac diseases. More recently, the study of LV long axis function with new echocardiographic and Doppler tech...

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...

If a billiard ball is fired from one focus of an elliptical table, its trajectory will pass alternately through the two foci of the table and will quickly become indistinguishable from a repeated tracing of the major axis of the table. In 3-dimensions, an ellipsoid of revolution has focusing properties similar to those of an ellipse. Frantz [1] has used this fact, together with geometrical opti...
