INTRODUCTION: Vertebral fractures are often the result of a progressive deformation process. Structural brittleness parameters should be considered relevant for such failure processes. Much of the previous work has been concerned with vertebral stiffness and strength but measures of brittleness such as work to fracture and failure displacement largely remained unexplored. In a previous study ex...

Using Analogy to Overcome Brittleness in AI Systems Matthew Evans Klenk One of the most important aspects of human reasoning is our ability to robustly adapt to new situations, tasks, and domains. Current AI systems exhibit brittleness when faced with new situations and domains. This work explores how structure mapping models of analogical processing allow for the robust reuse of domain knowled...

BACKGROUND This study compared two well-known computer-aided-design/computer-aided-manufactured (CAD/CAM) blocks (Paradigm MZ100 [3M ESPE] and Vitablocs Mark II [Vita] in terms of fracture toughness (Kic), index of brittleness (BI) and stress/strain distributions. MATERIAL AND METHODS Three-point bending test was used to calculate the fracture toughness, and the relationship between the Kic a...

In this work, poly(lactic acid) (PLA) a fully biodegradable thermoplastic polymer matrix was melt blended with three different epoxidized palm oil (EPO). The aim of this research was to enhance the flexibility, mechanical and thermal properties of PLA. The blends were prepared at various EPO contents of 1, 2, 3, 4 and 5 wt% and characterized. The SEM analysis evidenced successful modification o...
