We propose a novel approach called adaptive fuzzy ant-based routing (AFAR), where a group of intelligent agents (or ants) builds paths between a pair of nodes, exploring the network concurrently and exchanging obtained information to up-date the routing tables. Routing decisions can be made by the fuzzy logic technique based on local information about the current network state and the knowledge constructed by a previous set of behaviors of other agents. The fuzzy logic technique allows multiple constraints such as path delay and path utilization to be considered in a simple and intuitive way. Simulation tests show that AFAR outperforms OSPF, AntNet and ASR, three of the currently most important state-of-the-art algorithms, in terms of end-to-end delay, packet delivery, and packet drop ratio. AFAR is a promising alternative for routing of data in next generation networks.

Objective: To assess the efficacy of a curcumin supplementation on cognitive abilities in women suffering from premenstrual syndrome(PMS) and dysmenorrhea. Methods: A randomized, triple-blind, placebocontrolled trial was conducted from December 2019 to March 2020. A total of 124 women who had both PMS and dysmenorrhea were enrolled, and were equally and randomly assigned to the curcumin group or placebo group, 62 cases in each. Each subject received either a capsule containing 500 mg of curcuminoid, or a placebo daily, for 10 days(7 days before and until 3 days after the onset of menstrual bleeding) over 3 menstrual cycles. The cognitive abilities questionnaire was used to measures cognitive functions in 7 specific areas. Adverse reactions were monitored during and after the trial in both groups. Results: Administration of curcumin was associated with a significant increase in memory score(P=0.002), inhibitory control and selective attention(P=0.020), and total cognitive ability task(P=0.024). In addition, significant increments were found in scores of memory(3.5±3.1 vs. 0.4±3.8 in the curcumin and placebo groups, respectively;P=0.035), inhibitory control and selective attention(3.0±3.7 vs. 0.4±3.7;P=0.027) and total cognitive abilities(8.3±12.3 vs. 2.2±12.4;P=0.025) in the curcumin group versus placebo groups. Curcumin was safe and well-tolerable in current clinical trial. Conclusion: Curcumin has a beneficial efficacy on cognitive function scores in women with PMS and dysmenorrhea, with improvements in memory, inhibitory control and selective attention.(Registration No. IRCT20191112045424N1, available at: https://***)
