The synthesis, absorption and emission spectra, fluorescence quantum yields, and fluorescence lifetimes of three compound series of trans-4,4'-disubstituted aminostilbenes (1-3) are reported. The chromo-/fluoroionophoric behavior of the monoaza-15-crown-5- (A15C5) and monoaza-18-crown-6 (A18C6)-derived species (1A(5)()-3A(5)() and 1A(6)()-3A(6)()) in(More)
This study used the complex dynamic characteristics of chaotic systems and Bluetooth to explore the topic of wireless chaotic communication secrecy and develop a communication security system. The PID controller for chaos synchronization control was applied, and the optimum parameters of this PID controller were obtained using a Particle Swarm Optimization(More)
Photocatalysts produce free radicals upon receiving light energy; thus, they possess antibacterial properties. Silver (Ag) is an antibacterial material that disrupts bacterial physiology. Our previous study reported that the high antibacterial property of silver nanoparticles on the surfaces of visible light-responsive nitrogen-doped TiO2 photocatalysts(More)
Mast cells play an important role in allergic responses. During activation, these cells undergo degranulation, a process by which various kinds of mediators stored in the granules are released. Granule homeostasis in mast cells has mainly been studied by electron microscopy (EM), where the fine structures of subcellular organelles are partially destroyed(More)
This study reports a new microfluidic cell culture platform for real-time, in vitro microscopic observation and evaluation of cellular functions. Microheaters, a micro temperature sensor, and micropumps are integrated into the system to achieve a self-contained, perfusion-based, cell culture microenvironment. The key feature of the platform includes a(More)

We investigate the effect of caution in real operating and investment decisions — which can be thought of as real conservatism — on the firm's profitability and accounting conservatism. We document that firms exhibiting caution in their real decisions are characterized by higher profitability in the long run, lower probability of business failure, and lower(More)
