nerve regeneration. T main body of research involving bioactive glasses (BGs) has been devoted to applications in orthopedics and dentistry, given that the original composition 45S5 BioglassTM was developed to treat non-self-healing bone defects, such as bullet trauma or cancer. Because of their high bioactivity, BGs directly bond to bone. That bioactivity recently has been appreciated to exten...

An increasingly important requirement for software systems is the capability to adapt at run time in order to accommodate varying resources, system errors, and changing requirements. For such self-repairing systems, one of the hard problems is determining when a change is needed, and knowing what kind of adaptation is required. In this paper we describe a partial solution in which stylized arch...

Previous correlational research shows that childhood adversity is associated with earlier age of reproduction in humans and other species. Such studies, however, cannot show that stressful conditions cause earlier reproduction. Using the cold-pressor task, we built on previous work to test the idea that acute stress influences human reproductive and marital ideals, and that individual stress re...

In this paper we describe a new approach to repairing violations of integrity constraints in databases with null values. By adopting basic concepts from model-based diagnosis, we show how simultaneous reasons for violations of (di erent) constraints can be determined. These reasons, represented as sets of facts, directly indicate possible repair actions that guarantee to remove the observed vio...
