Abstract Security enhancement is important in terms of both classical and quantum information.The recent development of a quantum storage device is noteworthy, and a coherence time of one second or longer has been demonstrated.On the other hand, although the encryption of a quantum bit or quantum memory has been proposed theoretically, no experimen
Externalities of transport do not only depend on the number of kilometres driven, but also on factors such as road type, time of day, car type and on driving behaviour such as speed and acceleration.The present pricing system of car use and ownership in the Netherlands is such that the degree of differentiation is small, except for the car type asp
Fire has historically played an important role in shaping the structure and composition of Sonoran semi-desert grassland vegetation.Yet, human use and land management activities have significantly altered arid grassland ecosystems over the last century, often producing Bermuda novel fuel conditions.The variety of continuously updated satellite remo
OBJECTIVE: The aim of this study was to assess whether repetitive opening and closure of self-ligating bracket clips can cause plastic deformation of the clip.METHODS: Three types of active/interactive ceramic self-ligating brackets (n = 20) were tested: In-Ovation C, Quicklear and WOW.A standardized controlled device performed 500 cycles of openin
