Abstract: Bayesian knowledge tracing (BKT) is a knowledge inference model that underlies many modern adaptive learning systems. The primary goal of BKT is to predict the point at which a student has reached mastery of a… read more here.

Abstract: We report the manifestation of field-induced Berezinskii-Kosterlitz-Thouless (BKT) correlations in the weakly coupled spin-1/2 Heisenberg layers of the molecular-based bulk material [Cu(pz)_{2}(2-HOpy)_{2}](PF_{6})_{2}. At zero field, a transition to long-range order occurs at 1.38 K, caused by… read more here.
