    Prolactin response to thyrotropin-releasing hormone in children with Turner's syndrome and hyperthyroidism (1982)
    Springer
    European journal of pediatrics 138 (1982), S. 176-178 
    Details
    ISSN: 1432-1076
    Keywords: TRH ; Prolactin ; Hyperthyroidism ; Turner syndrome

    Topics: Medicine
    Notes: Abstract Plasma prolactin (PRL) response to synthetic thyrotropin-releasing hormone (TRH) was studied in 26 prepubertal and 19 pubertal children with constitutional short stature, 7 patients with Turner's syndrome and 10 patients with hyperthyroidism. The mean basal concentrations of plasma PRL did not differ among groups. In prepubertal children PRL responses to TRH were comparable in both sexes, while pubertal children plasma PRL levels after TRH in females were significantly higher (P〈0.05) than those in age-matched males. Plasma PRL levels after TRH in patients with Turner's syndrome were significantly higher (P〈0.05) than those in age-matched males, but were not significantly different from those in age-matched females. Plasma PRL response to TRH was markedly suppressed in patients with hyperthyroidism before treatment, but it returned to normal after treatment when patients became euthyroid. A significant correlation (P〈0.05) between peak concentrations of plasma PRL after TRH stimulation and plasma T3 but not T4 levels was observed. These data suggest that a sex difference in TRH-stimulated PRL secretion appears around puberty and that plasma PRL response to TRH is suppressed in children with hyperthyroidism. The magnitude of plasma PRL response to TRH is closely correlated with the severity of hyperthyroidism when judged by plasma T3 but not T4 concentrations.

    Prolactin response to arginine in children with hyperthyroidism and primary hypothyroidism (1982)
    Springer
    European journal of pediatrics 139 (1982), S. 118-120 
    Details
    ISSN: 1432-1076
    Keywords: Prolactin ; Arginine ; Hyperthyroidism ; Primary hypothyroidism
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Plasma prolactin (PRL) response to arginine was examined in 16 prepubertal and 18 pubertal children with constitutional short stature, 5 patients with hyperthyroidism and 4 patients with primary hypothyroidism. The mean basal concentration of plasma PRL was significantly higher (P〈0.01) in primary hypothyroidism than in other groups. Arginine infusion elicited significant (P〈0.05) rises in plasma PRL in all groups. The maximal increment of plasma PRL above the baseline level after arginine stimulation was significantly larger (P〈0.05) in pubertal than in prepubertal females and was significantly smaller (P〈0.05) in patients with hyperthyroidism than in age- and sex-matched controls. There was no sex difference in arginine-stimulated PRL secretion. These data suggest that arginine produces a significant increase in plasma PRL and the PRL response to arginine was greater in pubertal than in prepubertal children. Plasma PRL response to arginine is suppressed in children with hyperthyroidism and the basal plasma PRL is markedly elevated in primary hypothyroidism.

    Cooperative behavior of interacting robots (1998)
    Springer
    Artificial life and robotics 2 (1998), S. 62-67 
    Details
    ISSN: 1614-7456
    Keywords: Cooperative behavior ; Multi-robots ; Foraging behavior ; State transition diagram
    Source: Springer Online Journal Archives 1860-2000
    Topics: Computer Science
    Notes: Abstract We have researched the efficiency of cooperative behavior of interacting multirobots. In this paper, we generalize the definition of swarm intelligence and examine the emergence of the generalized swarm intelligence (here we call it “swarm function”) through the task of gathering pucks in a field by interacting simple robots. This robot has a drive system and the simplest means of interaction. The effectiveness of group behavior was studied for various (homogeneous, localized) puck distributions. To evaluate the efficiency of group behavior, we proposed a scaling relation between the task completion time and the number of robots, and examined the relation between the interaction duration and the efficiency of the group. We also proposed a simplified state transition diagram of the group and analysed their characteristics using it.

    A scaling law between the number of multirobots and their task performance (1999)
    Springer
    Artificial life and robotics 3 (1999), S. 122-126

    Topics: Computer Science
    Notes: Abstract We researched the efficiency of cooperative behavior using interacting multirobots. In this paper, we assume simple robots with a drive system and the simplest means of interaction, and examine the collective behavior through the task of gathering pucks in a field. The efficiency of group behavior is evaluated by the relation between the number of robots and the task completion time. To evaluate the efficiency of group behavior, we measure the exponent β, which is obtained from the scaling relation between the task completion time and the number of robots. The effectiveness of group behavior is investigated for fractal distributions of pucks. We research their behavior for fractal distributions of pucks and find out that the optimum value of β depends on the dimension of the puck distributions. We also propose a simplified state transition diagram of the group to analyse their characteristics. These results enable us to describe the condition of the field by a variable in the state transition diagram.
