We investigate the use of automata theory to model strategies for nonzero-sum two-person games such as the Prisoner's Dilemma. We are particularly interested in infinite tournaments of such games. In the case of finite-state strategies (such as ALL D or TIT FOR TAT) we use graph traversal techniques to show...
The frequency of exchanges was measured in a reversed
acrocentric compound X chromosome that is deficient for interstitial
heterochromatin. Previous studies on similar chromosomes
containing interstitial heterochromatin have demonstrated a very
low frequency of single exchanges, and high frequencies of the
double and no exchange classes. It has been postulated...
In three separate trials rats were fed either a basal diet deficient
in selenium and vitamin E or the same diet supplemented with
one or both of these factors. In addition to these treatments in two
of the trials, ethoxyquin was included to provide adequate lipid antioxidant
protection and to...
PART I. A chemical examination of the materials toxic to fish in
kraft pulp mill wastes has been made as part of a water pollution
study. Thirty gallons of "foul condensate" from a typical kraft mill
gave 14 g of organic material when extracted with methylene chloride,
and an additional...
A new photosystem-II mutant of the green alga Scenedesmus
obliquus D₃, strain PS-28, has been shown to lack a-tocopherol
(vitamin E). The photosynthetic activity of dark grown samples of
PS-28 is about 20% of the wild-type control. Culturing the mutant
at low light intentisites (10⁴ ergs/sec-cm ²) stimulates photosynthetic
activity...
