Abstract: This paper presents two versions of adaptive controllers for nonlinear bilateral teleoperators, each providing asymptotic convergence of velocity and position errors to zero, independent of constant time-delays. Moreover, the proposed schemes do not rely on the use of the scattering transformation. The paper also proves that the teleoperator is Input-to-State Stable from human operator and environment inputs to some synchronization signals. Simulations show the effectiveness of the proposed controllers.

By means of electrocorticographic recordings, we have examined the sleep-wake cycle as a functional maturity index, and its circadian and homeostatic mechanisms in prenatal (PM) and chronically (CM) protein malnourished young male rats. The effects of rapid eye movements sleep-deprivation (REMS-D), by the platform technique in a "conflict experiment" (i.e. recovery from REMS-D begun during the circadian phase of activity), revealed that in PM animals, wake (WAK) was increased significantly during recovery days 1 and 2 (RD1, RD2); and slow wave sleep (SWS) was reduced significantly during these days. Prenatal protein-malnutrition altered the phase of WAK and REMS rhythms, and the amplitude of SWS rhythm was decreased. The REMS compensatory increase after REMS-D (REMS rebound) was confined to the first 4-h block of the activity phase in all experimental groups and 24 h later another REMS rebound was displayed in PM animals. The paradoxical sleep-rebound in CM animals was significantly higher than control and PM rats and it was only shown at the first 4-h block after REMS-D. Before and after REMS-D the circadian distribution of both sleep states, and the electrocortical frequency bands showed different circadian phases at the same day-time in control, PM and CM rats. The aforementioned indicates that protein malnutrition exerts important effects on the circadian and homeostatic mechanisms driving sleep. Therefore, the temporal structure of the malnourished rats may not allow proper synchronization of some sleep parameters, particularly REMS, to the environmental time cues.",,,,,,"10.1080/10284150290018964",,,"http://hdl.handle.net/20.500.12104/43785","http://www.scopus.com/inward/record.url?eid=2-s2.0-0036213789&partnerID=40&md5=836b538d8ea565781cc0e4d3392fb2cc",,,,,,"2",,"Nutritional Neuroscience",,"91

Mellink, E.",,"2005",,"The Llanos de Ojuelos, a semiarid zone of northeastern Jalisco, Mexico, is formed mostly by natural grasslands and nopaleras (communities dominated by platyopuntias or flat-stemmed Opuntia cacti; both natural and cultivated), dotted with small reservoirs. This area is representative of many regions in the semiarid portion of Mexico's Mesa del Centro. With over 450 years since Spanish settlers occupied the area, human activities have modified native habitats and transformed the landscape. The ecological consequences of this transformation have not been recorded, but are likely to include negative impacts to many species of the native flora and fauna. Since there are no protected natural areas nor other efforts to conserve the semiarid biological communities of this region, and most of it has been modified, environmental conservation and management actions must rest on the tapestry of man-modified, or created, habitats. Although the three most characteristic habitats in the Llanos de Ojuelos are affected by human activities, they support a large part of the local vertebrate fauna. Sixteen of the vertebrate species in them are currently considered as being of conservation concern or requiring some type of protection or restoration. Overall, conserving and increasing herbaceous communities in the three habitats, as well as creating habitats through cultivated nopaleras, would contribute to increase faunal diversity and enhance some animal populations. Management schemes should focus on including different habitats within areas whenever possible, rather than attempting to manage tracks of single habitat isolated from each other. To allow for such adaptive management, any conservation actions should be followed by monitoring and management shifts. Also, if conservation projects are to be effective, they must consider the interests of the landholders. " Springer 2005.
