This paper presents a policy-supported architecture for adaptable service systems based on the combination of Reasoning Machines and Extended Finite State Machines. Policies are introduced to obtain flexibility with respect to specification and execution of adaptation mechanisms. The presented architecture covers two aspects: service system framework and adaptation mechanisms. The service syste...

Adaptation capabilities are becoming more and more popular in applications due to several facts, including heterogeneity of users, devices and physical contexts of use where applications are currently used. Adaptation is not per se good, and poor adaptations usually lead to disappointed users that reject or disable adaptation mechanisms. Therefore, in order for adaptation to reach the mainstrea...

phosphate (p) is one of the key substrates in energy metabolism and biosynthesis of nucleic acids and membranes. in order to identify molecular mechanisms involved in rice adaptation to p deficiency, we applied a proteomic approach to compare a rice parental line, nipponbare (sensitive), and its near isogenic line (nil6-4) (resistant). the experiment was conducted using a completely randomized ...

Prolonged exposure to visual stimuli, or adaptation, often results in an adaptation "aftereffect" which can profoundly distort our perception of subsequent visual stimuli. This technique has been commonly used to investigate mechanisms underlying our perception of simple visual stimuli, and more recently, of static faces. We tested whether humans would adapt to movies of hands grasping and plac...
