Mastigophorenes A—D (1—4) are dimeric herbertenetype sesquiterpenoids found only in the liverwort Mastigophora diclados (BRID.) NEES. They have usually been isolated with their precursor herbertenediol (5). Our recent investigation of a liverwort sample collected from Madagascar, however, did not show any trace of mastigophorenes A and B but revealed the presence of 3—5. The remarkable neurotro...

where we have assumed for this problem that X[n] is a discrete random variable that takes on the values {xi}, for i = 1, . . . ,m. From the problem statement we observe that the mean function μX [n] can be written as the sum of two periodic functions (i.e., one defined for n ≥ 1, another for n < 0, and a unique value at the origin n = 0). This observation will be made more concrete shortly; fir...

The Lucas-Lehmer (LL) test is the most efficient known for deterministically testing the primality of Mersenne numbers, i.e., the integers Ml = 2 l − 1, for l ≥ 1. The Mersenne numbers are so-called in honour of the French scholar Marin Mersenne (1588-1648), who in 1644 published a list of exponents l ≤ 257 which he conjectured produced all and only those Ml which are prime, for l in this range...

Introduction Sexual life and sexual satisfaction are associated with psychological well-being. It has already been shown that is related to myths or stereotypes, somesociodemographic sociosultural variables, gender. However, we have not met any study in which socioeconomic status, gender roles were taken together. Objectives The aim of this was investigate whether status predicts through roles....

--Study Objective: To demonstrate the safety of minimally invasive surgical treatment of 8 – 13 cm adnexal masses felt to be benign, to confirm the negative predictive value of ACOG Committee Opinion 280 for selecting women whose adnexal masses are unlikely to be malignant and, based on these data, to advocate for acceptance of a new treatment algorithm featuring Minimally Invasive Surgery in t...

Let W [n] be an independent random sequence with constant mean µ W = 0 and variance σ 2 W. Define a new random sequence X[n] as follows: X[0] = 0 X[n] = ρX[n − 1] + W [n] for n ≥ 1. (a) Find the mean value of X[n] for n ≥ 0. (b) Find the autocovariance of X[n], denoted as K XX [m, n]. (c) For what values of ρ does K XX [m, n] tend to G[m − n], for some finite-valued function G, as m and n becom...
