An axis parallel d-dimensional box is the cartesian product R1 × R2 × · · · × Rd where each Ri is a closed interval on the real line. The boxicity of a graph G, denoted as box(G), is the minimum integer d such that G can be represented as the intersection graph of a collection of d-dimensional boxes: that is two vertices are adjacent if and only if their corresponding boxes intersect. Permutati...

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 ...

Abstract If G is a group acting geometrically on CAT(0) cube complex X and if g ? has infinite order, we show that exactly one of the following situations occurs: (i) defines rank-one isometry ; (ii) stable centraliser SC ( ) = { h ? ? n ? 1, [ , ] 1} not virtually cyclic; (iii) Fix Y finite for every 1 sequence (Fix )) takes infinitely many values, where cubical component Roller boundary which...

Viscoelastic material behavior is often characterized using one of the three measurements: creep, stress-relaxation or dynamic sinusoidal tests. A two-stage numerical method was developed to allow representation of data from creep and stress-relaxation tests on the Fourier axis in the Laplace domain. The method assumes linear behavior and is theoretically applicable to any transient test which ...
