In this paper, a practical limit cycle predicting method is proposed for analyzing stability of nonlinear multivariable feedback control systems. The stable limit cycle of the considered system is found first by six criteria for unity loop gains, and then the stability is evaluated for variable loop gains. It needs only to check maximal or minimal frequency points of root-loci of equivalent gai...

BACKGROUND/AIM To investigate differences in state anxiety, spinal posture and mobility, postural competency, and stability across the menstrual cycle in active women. MATERIALS AND METHODS Thirteen physically active women (18-25 years) with a regular menstrual cycle were recruited. Anxiety with the Spielberger State Trait Anxiety Inventory; spinal posture, mobility, and competency with a Spi...

Within the standard RBC model, we examine issues of expectational coordination on the unique rational expectations equilibrium. Our study …rst provides a comprehensive assessment of the sensitivity of agents’plans and decisions to their short-run and long-run expectations. We show this sensitivity is much too great to trigger eductive coordination in a world of hyper-rational agents, who are en...

DNA DSBs (double-strand breaks) are a significant threat to the viability of a normal cell, since they can result in loss of genetic material if mitosis or replication is attempted in their presence. Consequently, evolutionary pressure has resulted in multiple pathways and responses to enable DSBs to be repaired efficiently and faithfully. Cancer cells, which are under pressure to gain genomic ...
