The axonal transport of the diverse group of polypeptides characteristic of slow component b (SCb), or Group IV, may be accomplished either by a bulk flow mechanism acting on each of the individual polypeptides or by their movement through the axoplasm as part of a physical complex or structural assembly. In order to determine if the SCb polypeptides travel as a cohesive unit (which would be co...

Assessing pain in neonates is a challenging problem. Neonates cannot describe their pain experiences but must rely exclusively on the judgments of others. Studies demonstrate, however, that proper diagnosis of pain is impeded by observer bias. It has therefore been recommended that neonatal pain assessment instruments include evaluations that have bypassed an observer. In this chapter, we descr...

In the U.S., there is evidence of a Trivers–Willard (T–W) effect in educational attainment, such that the sons of high status fathers attain more education than the daughters, and the daughters of low status fathers attain more education than the sons. This paper seeks to uncover the mechanisms by which this T–W effect occurs. Data are from the High School and Beyond Study by the U.S. National ...

This paper investigates the effects of mother’s age and parity on the prenatal allocation of resources in sons and daughters using a sample of 6994 in 20to 34-year-old mothers from Granada (Spain). This study tests the Trivers– Willard allocation model, which predicts that, depending on the mother’s condition, there can be a bias from 50/50 expected investment in the sexes. The results show tha...

this paper studies the perturbed klein-gordon equation by the aid of several methods of integrability. there are six forms of nonlinearity that are considered in this paper. the parameter domains are thus identified.
