The study focuses on problems related to the application of Artificial Intelligence (AI) in HumanComputer Interaction (HCI) for Educational Adaptive Hypermedia (EAH). It analyses how to apply Machine Learning (ML) techniques to support teachers in authoring teaching materials. AI principles and techniques are applied to the generation, testing and recommendation of teaching materials (computer ...

When non-surgical attempts prove unsuccessful or are contraindicated, surgical endodontic therapy is needed to save the tooth. The procedure usually consists of exposure of the involved area, root end resection, root end preparation and insertion of a root end filling material. Numerous materials have been suggested as root end filling materials. This article is a review of the literature on th...

An in vitro study was conducted to determine the adaptation of composite resin restorative material to rounded and acute-angled retention grooves of Class I cavity preparations on 24 extracted premolars. Two chemically cured (P-IO ® and Miradapt ®) and 2 light-cured (Prisma-Fil ® and FulFil ®) composite resin materials, after being coded to create a blind study, were injected into cavity prepar...

introduction: the aim of this study was to compare the marginal adaptation of mineral trioxide aggregate (mta) and calcium-enriched mixture(cem) cement apical plugs in open apex teeth in dry, blood- and saliva-contaminated canals. methods and materials: a total of 120 human extracted single-rooted teeth were used. the teeth were decoronated and canals were cleaned and shaped up to #80 k-files. ...

this study compared the marginal adaptation of mineral trioxide aggregate (mta) and mta-like materials as root-end fillings after incubation in phosphate buffer saline (pbs), a synthetic tissue fluid, for either 1 week or 2 months.in this experimental study, seventy-two extracted human single-rooted teeth were prepared and obturated with gutta-percha and ah26 sealer. the apical 3 mm of the root...

To respond to the need for new HIV prevention services for men who have sex with men (MSM) in the United States, and to respond to new data on the key role of main partnerships in US MSM epidemics, we sought to develop a new service for joint HIV testing of male couples. We used the ADAPT-ITT framework to guide our work. From May 2009 to July 2013, a multiphase process was undertaken to identif...

Using textures mapped onto virtual nonsense objects, it has recently been shown that early visual cortex plays an important role in processing material properties. Here, we examined brain activation to photographs of materials, consisting of wood, stone, metal and fabric surfaces. These photographs were close-ups in the sense that the materials filled the image. In the first experiment, observe...

This Supplement contains additional materials related to the paper PUnDA: Probabilistic Unsupervised Domain Adaptation for Knowledge Transfer Across Visual Categories. In particular, in Sec. 2 we present additional results that qualitatively demonstrate the advantages of our adaptation framework over competing approaches such as the ILS [2]. We contrast 2D embeddings of the features adapted by ...
