However, the use of cadaveric biologic mesh has been(More)
The forest canopy is important in maintaining the diversity, resilience, and functioning of forest ecosystems. As new access techniques, such as the use of giant construction cranes, increase the interest and information about forest canopies, new tools and analytical approaches will be needed to manage, analyze and compare data from various studies. Canopy(More)
The concept of Adaptive Memory coupled with advances in neighborhood structures derived from dynamic and adaptive search constructions have been the source of numerous important developments in metaheuristic optimization throughout the last decade. These innovations have been the key to the most successful results in a wide range of applications in(More)
BACKGROUND Amniotic membrane is tissue obtained from human placenta rich in cytokines, growth factors, and stem cells that possess the ability to inhibit infection, improve healing, and stimulate regeneration.
