Recently, more and more attention is paid to reversible data hiding (RDH) in encrypted images, since it maintains the excellent property that the original cover can be losslessly recovered after embedded data is extracted while protecting the image content’s confidentiality. All previous methods embed data by reversibly vacating room from the encrypted images, which may be subject to some error...

Today’s computers are based on irreversible logic devices, which have been known to be fundamentally energy-inefficient for several decades. Recently, alternative reversible logic technologies have improved rapidly, and are now becoming practical. In traditional models of computation, pure reversibility seems to decrease overall computational efficiency; I provide a proof to this effect. Howeve...

The discussion considers the current status of reversibility of sterilization in the US and describes clinical and experimental efforts for developing techniques designed for reversibility. It focuses on regret following sterilization, reversal potential of current sterilization techniques, patient selection, current reversal techniques, results of sterilization procedures, experimental approa...

Acylhydrazone-based (macro)molecules display an increasingly broad spectrum of applications, from small therapeutic molecules and metal-ions probes to self-healing films biorelevant dynamic polymers. The acylhydrazone function is indeed prime interest since its unique design combines hydrogen bonds, pH-dependent reversibility, ability undergo molecular exchanges, a possible polyvalency. However...
