Factors and factorizations of graphs—a survey
Journal of Graph Theory, 1985AbstractA degree factor of a graph is either an r‐factor (regular of degree r) or an [m, n]‐factor (with each degree between m and n). In a component factor, each component is a prescribed graph. Both kinds of factors are surveyed, and also corresponding factorizations.

Journal of the London Mathematical Society, 1998
A noninjective bounded-to-one factor map from an irreducible shift of finite type onto a sofic system can be factored as a composition of other such maps in only finitely many ways (up to isomorphism). This generalizes to factor maps from systems with canonical coordinates to finitely presented dynamical systems. The proofs are constructive and rest on

Scientific American, 2014
The article focuses on the physiological and cognitive differences between humans and chimpanzees. Topics include how Homo sapiens became the dominant species, how human behavior differs from the behavior of apes, and the link between language and human evolution. Information is provided on the brain size differences between humans and chimpanzees.

Antihemophilic Factor (Factor VIII)
Annals of Internal Medicine, 1978Antihemophilic factor (Factor VIII) is an agent in normal plasma that corrects the coagulative defect of classic hemophillia. The plasma of hemophiliacs contains normal amounts of a variant of antihemophilic factor deficient in clot-promoting properties. In contrast, von Willebrand's disease is usually associated with a true deficiency of this protein.

Factoring Effectiveness Factors!
Journal of the Operational Research Society, 1990It has previously been suggested that the effectiveness of strategic planning systems may be characterized in terms of a multi-attribute framework. This paper explores the possibility of reducing the postulated set of attributes to an ‘irreducible core’ by means of a factor analysis.

Growth Factors: A scattering of factors
Current Biology, 1994Hepatocyte growth factor/scatter factor is a multifunctional growth factor with varied properties: more and more polypeptide factors are being discovered that share these characteristics.

CRC Critical Reviews in Clinical Laboratory Sciences, 1980
It has been more than 30 years since Dr. H. S. Lawrence first reported that it was possible to transfer delayed-type hypersensitivity from sensitized donors to unsensitized recipients with lysates of blood leukocytes. During recent years, research from several laboratories has demonstrated that this effect is immunologically specific.
