Factors involved in the paradox of reverse epidemiology
Clinical Nutrition, 2010The hypothesis of reverse epidemiology holds that some cardiovascular risk factors, such as obesity, hypercholesterolemia and hypertension, in the elderly or in some chronic diseases are not harmful but permit better survival. However, this phenomenon is controversial and the underlying reasons are poorly understood.To search for factors simultaneously

On factors affecting the reversible superrrecipitation of actomyosin
Biochimica et Biophysica Acta, 1950Abstract 1. 1. The reaction between actomyosin and ATP was studied by measuring light transmission within various angles. 2. 2. The effects of PH and temperature on superprecipitation as measured by light transmission is described. 3. 3. The temperature effect is reversible within the PH range 8.0–9.5. 4. 4.

On the factors controlling the reversibility of DNA denaturation
Journal of Molecular Biology, 1962The experiments described in this paper distinguish two processes which lead to a reversal of DNA denaturation and to the re-formation of long-stacked arrays of nucleotide pairs. Type I reversibility is a very rapid intramolecular process which occurs in DNA preparations from viral, bacterial and animal sources, in solvents varying greatly in ionic ...

Reversible component transforms by the LU factorization
28th Picture Coding Symposium, 2010A scaled transform is defined for a given irreversible linear transformation based on the LU factorization of a nonsingular matrix so that the transformation may be computed in a lifting form and hence may be reversible. Round-off errors in the lifting computation and the computational complexity are analyzed.

The Effects of Temporal Factors on Reversal and Half-Reversal Shifts
The American Journal of Psychology, 1974The stimuli were nonsense figures, and the design varied type of shift (reversal, half-reversal), amount of preshift training (undertraining, fixed-trial overtraining, behaviorally defined overtraining), and temporal factors (group 20-.6, group 3-3, group .6-.6; the first digits show intertrial interval in seconds, and the second digits show ...

Factor Allocation as Reverse Attribution
The Journal of Portfolio Management, 2021Multifactor models and the construction of factor portfolios are by now pervasive in investment management. Active factor allocation can be challenging, however, given the difficulty in generating accurate point estimates for ex ante factor alphas. To overcome this challenge, the present article describes a technique that gives managers the ability to ...

Reverse mathematics of prime factorization of ordinals
Archive for Mathematical Logic, 1999One of the earliest applications of Cantor's Normal Form Theorem is Jacobstahl's proof of the existence of prime factorizations of ordinals. An ordinal \(\alpha\) is prime if whenever \(\alpha = \lambda \rho\), either \(\rho = 1\) or \(\rho = \alpha\).

Towards an Ontology of Factors Influencing Reverse Engineering
13th IEEE International Workshop on Software Technology and Engineering Practice (STEP'05), 2005In the context of the workshop's discussion on a general framework for empirical studies on reverse engineering, this paper stresses the need for an ontology of factors influencing the application of reverse engineering techniques. Through an integration of existing work, this paper proposes a tentative ontology.
