Photo-induced reversible sorption of azo dyes on titania xerogels is observed, which is based on the photo-switchable change of the acetylacetonato anchors in the xerogels. The photoisomerization of azo compounds that regulates many gate-keeper-like host-guest interaction systems is excluded as the determinant.

There are several techniques that reduce leakage power in efficient way but the disadvantage of each technique limits the application of each technique. In this paper sleepy keeper approach is introduced to reduce the power dissipation of the circuit in idle state when its logic is not needed. The sleepy keeper approach uses traditional sleep transistors and two additional transistors which are...

Artificial Intelligence based foodstuff monitoring system is used for inventory management in industrial kitchens, restaurants, canteens, vegetable stores and so on. If the store keeper not available to monitor grocery orders, process will be risky. The proposed method considers level estimation detection using ultrasonic sensor if container empty then information sent keeper. By this method, i...

We report acute tetraplegia caused by rat bite fever in a 59-year old man (snake keeper) and transmission of Streptobacillus moniliformis. We found an identical characteristic bacterial pattern in rat and human samples, which validated genotyping-based evidence for infection with the same strain, and identified diagnostic difficulties concerning infection with this microorganism.

A highly efficient nanoreactor that contains silver nanoparticles in hollow silica spheres and an interpolymer network as a gate-keeper has been developed following a facile procedure. The fast "signal-triggered" switch of the smart network results in a high reactivity and a high response rate, yielding improved potential for many practical applications.
