When sensors and actuators communicate with a remote controller over a multipurpose network, improved techniques are needed for state estimation, determination of closed-loop stability and controller synthesis. ABSTRACT | Networked control systems (NCSs) are spatially distributed systems for which the communication between sensors, actuators, and(More)
It is still not clear which group of ammonia-oxidizing microorganisms plays the most important roles in nitrification in soils. Change in abundances and community compositions of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) under long-term different nitrogen (N) fertilization rates were investigated in an acidic luvisols soil using(More)
iv Acknowledgements For the completion of this work I am grateful to my adviser Professor João Pedro Hespanha for his support and guidance. João has much for me to learn from, professionalism and dedication, among many others. The knowledge and skills I learned from him will be my great assets for all the years to come. Never would I forget of his warmth(More)
— An LTI estimation framework is proposed for networked control systems (NCS), in which local Kalman filter estimates are sent to the remote estimator. Both controlled and uncontrolled data communications are considered. For uncontrolled communication, minimum rate requirements are given for stochastic moment stability, which depend only on the least stable(More)
Because of the widespread use of antibiotics in animal breeding, the agricultural application of animal manure can lead to the introduction of antibiotics, antibiotic-resistant bacteria and antibiotic resistance genes to the soil and surrounding environment, which may pose a threat to public health. In this study, we investigated the status of(More)
Trehalose, a nonreducing disaccharide which accumulates dramatically during stationary phase or under oxidative stress, is well known as a stress protectant in several organisms. Here we investigated the putative correlation of trehalose with Cap1p, which is a basic region-leucine zipper (bZip) transcription factor participating in oxidative stress(More)
AIM To test the role of the Beclin 1-dependent autophagy pathway in brain damage during cerebral ischemia. METHODS Focal cerebral ischemia was established in rats using a middle cerebral artery occlusion (MCAO) model. A lentiviral vector-associated RNA interference (RNAi) system was stereotaxically injected into the ipsilateral lateral ventricle to reduce(More)
OBJECTIVES To study the cytotoxicity induced by haematoporphyrin monomethyl ether (HMME)-mediated sonodynamic therapy (SDT) on C6 glioma cells. METHODS The potent photosensitizer HMME was used as the sensitizer. Rat C6 glioma cells were incubated with HMME (10 microg/mL) in the dark for 2 h and then subjected to ultrasound treatment at 1.0 MHz and 0.5(More)
