16. Effects of physical activity and gravitational stress on cardiovascular control
Abstract : The long-term goal of the present work was to characterize the responses to gravitational challenges in exercising humans after long-term head-down-tilt bedrest (HDT). HDT is a simulation of weightlessness with respect to effects on the systemic circulation, and previous studies in resting men have suggested that impairments of arterial baroreflexes contribute to the orthostatic intolerance seen after HDT and spaceflight.

17. Neural mechanisms for the visual control of spatial orientation and locomotion : electrophysiological and behavioural studies of the supraspinal control of posture and steering in the lamprey central nervous system, with reference to visuo-motor mechanisms
Abstract : Neural mechanisms for the supraspinal control of posture and steering, in particular visuo-motor control and visuo-vestibular interaction in postural control, were investigated, using the lamprey as a model system. Behavioural experiments on intact and chronically lesioned animals, intra- and extracellular recordings in vitro and retrograde staining of neurons with horseradish peroxidase were utilized.

18. Apnea, small for date and autonomic imbalance : risk factors in relation to SIDS
Abstract : SIDS (Sudden Infant Death Syndrome) is defined as an infant who has died suddenly and its cause "remains unexplained after a thorough case investigation, including performance of a complete autopsy, examination of the death scene, and review of the clinical history". An infant who during sleep has been found apneic, pale or cyanotic and limp, and has required either vigorous stimulation or cardiopulmonary resuscitation is defined to have been affected of an Apparent Life Threatening Event (ALTE).

19. Bandit Methods for Network Optimization : Safety, Exploration, and Coordination
Abstract : The increasing complexity of modern mobile networks poses unprecedented challenges to their optimization. Mobile Network Operators (MNOs) need to control a large number of network parameters to satisfy the users’ demands. READ MORE

20. Functional Interfaces in Epitaxial YBa2Cu3O7-δ with Artificial Grain Boundary Junctions
Abstract : The properties of superconducting devices based on grain boundaries in YBa2Cu3O7-δ (YBCO) thin films are determined by the atomic structure of the grain boundary plane. To obtain these devices based on single grain boundaries, biepitaxial fabrication techniques has been used. READ MORE
