Chung, Diaconis, and Graham considered random processes of the form Xn+1 = 2Xn + bn (mod p) where X0 = 0, p is odd, and bn for n = 0, 1, 2, . . . are i.i.d. random variables on {−1, 0, 1}. If Pr(bn = −1) = Pr(bn = 1) = β and Pr(bn = 0) = 1 − 2β, they asked which value of β makes Xn get close to uniformly distributed on the integers mod p the slowest. In this paper, we extend the results of Chun...

OBJECTIVE Bombesin (BN) and the mammalian homologue gastrin-releasing peptide (GRP) are known trophic factors, neurotransmitters and paracrine hormones. BN/GRP has not previously been demonstrated in synovial fluid. In this study, the amounts of BN/GRP and substance P (SP) present in synovial fluid from the knee joints of patients with rheumatoid arthritis (RA) and of healthy controls were meas...

BACKGROUND Bulimia Nervosa (BN) is believed to be caused by an interaction of genetic and environmental factors. Previous studies support the existence of a bulimia-related endophenotype as well as disturbances in serotonin (5-HT) transmission. We studied serotonin transporter (SERT) binding in BN, and to investigate the possibility of a SERT-related endophenotype for BN, did this in a sample o...

BACKGROUND The aim of this study was to examine whether there is a difference in the dimensions of attachment and difference in emotional regulation between the group of female patients suffering from bulimia nervosa (BN) and the control group. We also wanted to examine whether emotional regulation has a mediating role in the relationship between dimensions of attachment and severity of BN symp...
