We formulate and analyze a two-group, selective-mixing, susceptible-infective-susceptible (SIS), sexually transmitted disease (STD) model where the infection-dependent desirability and acceptability in partnership formations are zero at high infection levels. We analyze two strategies to limit the spread of the epidemic by avoiding forming partnerships with people in a highly infected group. In...

this paper proposes a discrete-time repetitive optimal control of electrically driven robotic manipulators using an uncertainty estimator. the proposed control method can be used for performing repetitive motion, which covers many industrial applications of robotic manipulators. this kind of control law is in the class of torque-based control in which the joint torques are generated by permanen...

Epidemiological data suggest that postprandial hyperglycaemia and hypoglycaemia are potential risk factors for cardiovascular disease. However, the effects of repetitive postprandial glucose spikes, repetitive hypoglycaemia, and their combination on the progression of atherosclerosis remain largely unknown. The present study investigated the effects of rapid rises and falls in glucose, and thei...

REPETITIVE MECHANICAL STIMULATION CAUSES DEPRESSION OF EXCITABILITY IN ISOLATED PACINIAN CORPUSCLES: the mechanical threshold of the sense organ for producing nerve impulses increases progressively with time of repetitive stimulation. The effect is completely reversible; it can be elicited with repetitive stimuli of less than threshold strength. Within certain limits, the depression increases a...

In this paper, we investigate the parameterization of all robust stabilizing repetitive controllers for single-input/single-output continuous time non-minimum phase systems. The repetitive control system is a type of servo mechanism designed for a periodic reference input. When repetitive control design methods are applied to real systems, the influence of uncertainties in the plant must be con...

Restricted, repetitive behavior is one of the three diagnostic domains for autism spectrum disorders, and commonly observed in a number of other neurodevelopmental disorders. Despite its clinical significance, effective treatments for restricted, repetitive behavior are limited including few, if any, pharmacological interventions with demonstrated efficacy. This is in large measure due to the l...

background traumatic brain injury (tbi) is a worldwide problem, especially in countries with high incidences of road traffic accidents such as iran. patients with a single occurrence of tbi have been shown to be at increased risk to future tbi. this study presents incidences and characteristics of repeated traumatic brain injury (rtbi) in iran. materials and methods during one year, all admitte...

Repetitive genomic sequences might have various structural features and properties distinct from those of the known transposable elements (TE). Here, the content and properties of the repetitive sequences present in a 200-kb region around the rice waxy locus were analyzed using the available rice genomic database. In our previous Southern blotting analysis, 70% of the segments in this region sh...
