A recently developed statistical model for first-order scattered fields is used to predict
the normalized covariance function of an underwater acoustic signal backscattered by a
hypothetical school of fish. The fish school is configured as an oblate spheroid with the
individual fish Poisson distributed within the school.
Empirical covariance functions...
Crossmatings were accomplished among three semi-closed lines within a population of pigs, for the purpose of investigating effects of crossbreeding on reproductive traits. Two of the lines were purebred (Berkshire and Yorkshire); the third line ("Composite") consisted of descendants from inter se matings among offspring of crosses of the Berkshire...
