on it throughout the operation, and when it was over bamboo poles were slid into the hem on each side and two looped iron rods passed over the ends of the poles to keep the stretcher from sagging. The patient was then lifted on to a wheeled carriage and taken to his bed side. Here the difficulty of lifting the patient off the stretcher into bed without any exertion on his part was often very ap...

We obtain a chain condition for dividing in an arbitrary theory and a new and shorter proof of a chain condition result of Shelah for simple theories.

We suggest that the components of the well known divide-and-conquer paradigm can be prootably presented as independent constructs in a skeletal parallel programming model. We investigate this proposal in the context of a rendition of Batcher's bitonic sorting algorithm in which the nested parallel structure of the program is neatly abstracted from the low level detail of a at presentation. We s...

than inhibiting cell division? The quest to identify means to stop cells from proliferating has driven generations of researchers to investigate the mechanisms regulating the cell division cycle. The cell cycle consists of several phases. Progression from one phase to the next depends on the activity of specific proteins. In order to pass the checkpoints between two phases, several classes of p...
