Recognition of Uni-Stroke Characters with Hand Movements in 3D Space Using Convolutional Neural Networks.

Hand gestures are a common means of communication in daily life, and many attempts have been made to recognize them automatically. Developing systems and algorithms to recognize hand gestures is expected to enhance the experience of human-computer interfaces, especially when there are difficulties in communicating vocally. A popular system for recognizing hand gestures is the air-writing method, where people write letters in the air by hand.

In vivo comparative investigation of three synthetic graft materials with varying compositions processed using different methods.

Purpose: The aim of this study was to compare the osteoconductive potential and bone-healing pattern of biphasic calcium phosphates (BCPs) with varying compositions produced using different processing methods.

Materials And Methods: Ten male New Zealand white rabbits were used. Four circular defects with a diameter of 8 mm were made in the rabbit calvarium.

The Role of Two Different Collagen Membranes for Dehiscence Defect Around Implants in Humans.

The aim of this study was to elucidate the role of 2 types of collagen membranes (cross-linked vs noncross-linked) used in conjunction with autogenous or allogenic bone followed by xenogeneic bone particles for dehiscence defect around implants in humans. Experimental groups were divided into 2 groups: Group CL (cross-linked, Ossix Plus, n = 24 implants, 16 patients) and Group NCL (noncross-linked, Bio-Gide, n = 25 implants, 18 patients). At the time of implant insertion and uncovery surgery, measurements of the dehiscence bony height, width, and surface area were made.
