Anatomy and Embryology, 1986
The emphasis of this review is on the primitive streak of the chick embryo, collated with such information as is available on the mouse embryo. Little modern work has been published on any reptile primitive streak. The following topics are considered: evolutionary significance; formation of the primitive streak; ingression and de-epithelialisation; the

ACM SIGGRAPH Computer Graphics, 1972
In developing the graphics computer system BIOMOD, we were concerned primarily with the user-system interface. Rather than developing a formal higher-level language specific to modeling in biology, it appeared more fruitful to examine empirically the activities of the modeling process, and to attempt to design so that these activities would be simple ...

M AGIC, SORCERY, FATE-these are thought to be the causes of sickness by the Ha tribe of Tanganyika, East Africa. Cures are arrived at through the rituals of the witch doctor. As for preventive medicine, you try not to let yourself be poisoned, and you take what steps you can to keep the spirits contented. But, in spite of witch doctor and propitiation,

Journal of Molecular Evolution, 1977
The sequences of Petromyzon and Aplysia globins are compared with the postulated vertebrate and mollusc-vertebrate ancestors to see if differences exist in the rates of evolution of different types of residue positions. Between the mollusc-vertebrate ancestor and Aplysia globin there is no very striking pattern of changes except that the interior ...

Summary: The primitive words, those which cannot be written as the power of another word, appear in many places in formal language theory, coding theory, combinatorics on words, etc. An intriguing problem in this area concerns the language \(Q\), of all primitive words over the alphabet \(\{a,b\}\). Up to now, it has resisted to all attempts of proving

Journal of the American Psychoanalytic Association, 2017
Traditional psychoanalytic theories of development hold that the adult neurotic can regress, or has already regressed, to the childhood arrests and/or fixations in which his pathology originated. More recent critiques have called this possibility into question.
