Divergencies were attributed to certain insufficiencies in factor analysis and to the fundamental views of analysts with regard to emphasis upon ...

On the Stability of Factorization Factors
1987The present chapter is devoted to the study of the behaviour of the factorization factors under small perturbations of the matrix function G. Here we encounter another qualitative difference between the matrix case (n > 1) and the scalar one (n = 1). It appears that the partial indices of a matrix function and the factorization factors G± are unstable,

Spinal and supraspinal factors in human muscle fatigue.
Physiological Reviews, 2001Muscle fatigue is an exercise-induced reduction in maximal voluntary muscle force. It may arise not only because of peripheral changes at the level of the muscle, but also because the central nervous system fails to drive the motoneurons adequately ...

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.

It is common practice to refer to a factor premium’s current valuation when assessing its attractiveness—in effect using a single-value-factor model to gauge whether the factor is rich, fairly valued, or cheap. Meanwhile, studies have investigated how some factor premia are exposed to other factor premia in order to characterize their behavior over ...
