Two natural kinds of problems about “structured collections of symbols” can be generally referred to as the LARGEST COMMON SUBOBJECT and the SMALLEST COMMON SUPEROBJECT problems, which we consider here as the dual problems of interest. For the case of rooted binary trees where the symbols occur as leaf-labels and a subobject is defined by label-respecting hereditary topological containment, bot...

Plant species present a complex array of biochemicals to herbivores that in conjunction with a plant’s physical structure influence intake. Our objective was to determine the role of postingesŽ . tive feedback from macronutrients on the ingestion of a low-quality forage by sheep OÕis aries . We compared the ingestive behaviour of two groups of lambs conditioned with intraruminal Ž . Ž . infusio...

If a and b are degrees of unsolvability, a is called a minimal cover of b if b<a and no degree c satisfies b<c<a. The degree a is called a minimal cover if it is a minimal cover of some degree b. We prove by a very simple argument that 0" is not a minimal cover for any n. From this result and the axiom of Borel determinateness (BD) we show that the degrees of arithmetical sets (with their usual...

A new research multiprocessor named ZMOB is described, and its significance to AI research is surveyed and characterized. ZMOB, under current construction and scheduled for completion late Fall 1981. is a 256 processor machine with a high speed ,interprocessor communications system called the "conveyor belt", a non-blocking, 20 megabyte/second message switcher. Because of its large number of pr...

Sediment chronologies based on radioisotope depth profiles were developed at two sites in the San Francisco Bay estuary to provide a framework for interpreting historical trends in organic compound and metal contaminant inputs. At Richardson Bay near the estuary mouth, sediments are highly mixed by biological andror physical processes. Excess Th penetration ranged from 2 to more than 10 cm at e...
