We consider the problem of characterizing the sets of externally and internally active elements in a matroid. The main result is a canonical decomposition of the set of elements of a matroid on a linearly ordered set into external and i...

Drosophila genetics has provided the Hedgehog signaling pathway with roughly ordered components, but few mechanistic connections. Several studies now show that the kinesin-related protein Costal-2 provides a physical link between the tr...

Based on reported animal studies, the case report presented demonstrates the use of tooth-borne distraction osteogenesis for mandibular widening of 1 cm in order to avoid extraoral distraction devices. Detrimental side effects on health...

Input systems have been developed that enables severely disabled persons to control the patient-operated selector mechanism which will increase their independence. The dentist can play an important role in the team approach to this mult...

An explicit formula for the solution of the discrete version of the Fisher-Wright Nike Air Max 2014 Canada selection model is given. Mathematically, the equations of this model form a system of non-linear difference equations of first o...

1.1. Western Grey Kangaroos generally inhabit more arid and hotter regions than Eastern Greys.2.2. Ears from Western Greys are significantly thinner, less furred and have smaller, thinner hairs than those from Eastern Grays.3.3. Ears ma...

Indomethacin at a concentration (1O−4 M) Nike Air Max 90 which depressed the effect on O2− generation by fMet-Leu-Phe, markedly enhanced O2−, generation by both 1-oleoyl-2-acetylglycerol and the calcium ionophore, A23187. These re...

This paper develops a three-country extension to the Ricardian model with a continuum of goods. In contrast to the standard two country version, uniform technical progress in one country is shown to make the country which is a close sub...

The preparations of the racemic [Cr(ox)(AA)2]ClO4 salts (AA = en, RS-pn and tn) are described. These have been resolved by the method of racemic modifications using the monohydrogen dibenzoyl-(+)-tartrate anion and the less soluble dias...

Fish form social aggregations called shoals which often consist of fish with similar morphologies. Experiments using zebrafish pigment variants demonstrate that fish can select shoal mates solely on the basis of their color patterns, an...
