We prove a theorem in 3-dimensional topological field theory: Reshetikhin–Turaev theory admits nonzero boundary iff it is Turaev–Viro theory. The proof immediately implies characterization of fusion categories terms dualizability. Our results rely on (special case of) the cobordism hypothesis with singularities. main applies to physics, where an obstruction gapped quantum system admitting Appen...

background and purpose: medical education programs' success depends on the efficiency and adequacy of clinical experiences, one of the most important factors recognized in this field is learning atmosphere and environment. professor’s features, students' learning experiences and characteristics of the program implementation environment are of those cases that vary in different universities. one...

Virtual worlds are receiving increasing attention as a promising technology to engage students in learning. However, the use of these technologies for educational purposes is currently hampered by a lack of understanding of how better learning can be achieved in such environments. Thus motivated, this study uses the lenses of flow and social translucence of technology theories to model the indi...
