In this paper, a novel adaptive dynamic programming (ADP)-based event-triggered safe control method is proposed to solve the zero-sum game problem of nonlinear safety-critical systems with safety constraints and input saturation. First, barrier function-based system transformation, saturation transformed into an equivalent problem, so as guarantee that does not violate constraints. Furthermore,...

BACKGROUND Individuals with infantile cerebral palsy have multiple disabilities. The most conspicuous syndrome being investigated from many aspects is motor movement disorder with a spastic gait pattern. The lung function of adults with spasticity attracts less attention in the literature. This is surprising because decreased thoracic mobility and longstanding scoliosis should have an impact on...

The paper derived a critical condition for matter equilibration in heavy ion collisions using a holographic approach. A gravitational shock waves with infinite transverse extension is used to model infinite nucleus with an intrinsic saturation scale. We constructed the trapped surface in the collision of two asymmetric shock waves and formulated a critical condition for matter equilibration in ...

The saturation of excitonic absorption in strained InGaAs/AlGaAs quantum wells is systematically measured as a function of strain. By comparison with an unstrained GaAs/AlGaAs quantum well sample a reduction by a factor of up to 9 in the saturation carrier density is observed in strained samples with indium concentrations of 10% ‘and 15%. Very low saturation densities, as low as 0.82X 1017 cmm3...

A combined stopped flow-laser photolysis apparatus was used to measure the quantum efficiency for removal of carbon monoxide bound to human hemoglobin as a function of fractional CO saturation. This flow-flash technique allows the properties of partially liganded hemoglobin molecules, which are sparsely populated under equilibrium conditions, to be conveniently studied. Experiments performed at...

BACKGROUND In the UK approximately 1 in 140 people are homozygous for the C282Y mutation of the HFE gene and are at risk from iron overload caused by genetic haemochromatosis (GH). Early detection can prevent organ damage secondary to iron deposition and increase life expectancy. AIM To screen for GH in all blood samples sent to the laboratory for routine liver function tests in which raised ...
