Direct and Indirect Methods for Studying Human Gut Microbiota

Molecular biological methods for studying the gut microbiota: the EU human gut flora project.

Seven European laboratories co-operated in a joint project (FAIR CT97-3035) to develop, refine and apply molecular methods towards facilitating elucidation of the complex composition of the human intestinal microflora and to devise robust methodologies for monitoring the gut flora in response to diet. An extensive database of 16S rRNA sequences for tracking intestinal bacteria was generated by ...

Studying Direct and Indirect Human Influence on Consensus in Swarms

Many cooperative control problems ranging from formation following, to rendezvous to flocking can be expressed as consensus problems. The ability of an operator to influence the development of consensus within a swarm therefore provides a basic test of the quality of human-swarm interaction (HSI). Two plausible approaches are : Directdictate a desired value to swarm members or Indirectcontrol o...

Psychobiotics and Brain-Gut Microbiota Axis

Fermented foods containing probiotic bacteria have been used for many years to improve the health or treatment of some diseases. Nowadays, the Therapeutic properties of probiotics are becoming more and more obvious to everyone, insofar as in recent years, more attention has been paid to the potential relation between gut microbiota and mental health. Several studies have shown that intestinal m...

Direct and indirect methods for trajectory optimization

This paper gives a brief list of commonly used direct and indirect efficient methods for the numerical solution of optimal control problems. To improve the low accuracy of the direct methods and to increase the convergence areas of the indirect methods we suggest a hybrid approach. For this a special direct collocation method is presented. In a hybrid approach this direct method can be used in ...
