The regenerative potential of dental pulp is very limited in mature teeth. However, our improved understanding of pulpal inflammation and repair and improved dental materials and technologies make vital pulp therapy a viable alternative to root canal treatment. This article explores our knowledge in this regard and the future potential of saving or even regenerating the pulp as a routine dental

Broadcasting live digital TV to a small battery-powered handheld device is very challenging. One of the most promising technologies to provide such services is DVB-H (Digital Video Broadcasting over Handheld). Power consumption has always been one of the most crucial challenges for handheld devices. In this paper, a novel Adaptive Modulation and Coding (AMC) framework is proposed for DVB-H syst...

Automatic identification technologies, such as bar coding and radio frequency identification, are ubiquitous in everyday life but virtually nonexistent in the operating room. User expectations, based on everyday experience with automatic identification technologies, have generated much anticipation that these systems will improve readiness, workflow, and safety in the operating room, with minim...

Using panel data on investment of firms in energy saving technology, we measure the impact of the payback period of the technology on the probability to adopt the technology in the absence of tax and subsidy incentives. We find that the decision rules to adopt energy saving technology differs substantially between different types of firms, i.e. for-profit/notfor-profit as the decision to adopt ...
