Introduction: Pregnancy, especially the first pregnancy and childbirth, affects the women’s quality of life. Improving information-seeking behavior facilitates the decision-making process of women during pregnancy and postpartum. The aim of this study was to investigate the health information-seeking behavior of Iranian first-time mothers and first-time pregnant women. Methods: This research...

The problem of computing the moment generating function of the first passage time T to a > 0 or −b < 0 for a one-dimensional Wiener process {X(t), t ≥ 0} is generalized by assuming that the infinitesimal parameters of the process may depend on the sign of X(t). The probability that the process is absorbed at a is also computed explicitly, as is the expected value of T .

We use only the classic basic ballot result and simple combinatorial arguments to derive the distributions of the first passage time and the number of visits in the usual random walk model. © 2011 Elsevier B.V. All rights reserved.

In this paper, we study the concept of generalized differentiability for fuzzy-valued functions on time scales. Usingthe derivative of the product of two functions, we provide solutions to first order linear fuzzy dynamic equations. Wepresent some examples to illustrate our results.
